The term "first/second" merely distinguishes between different objects and does not denote that there is the same or a relationship between the two.
In one aspect, referring to fig. 1, an electromagnetic locking mechanism is provided, where the electromagnetic locking mechanism includes a moving member 1, a housing 2, an electromagnet assembly 3, a clamping assembly 4, and an engaging assembly 5. The housing 2 is formed with a receiving chamber 2a and a holding opening 2b, the holding opening 2b being for penetrating the mover 1. The electromagnet assembly 3 is positioned in the accommodating cavity 2a, and the electromagnet assembly 3 is fixedly connected to the shell 2. Specifically, the electromagnet assembly 3 includes a yoke and a coil, the coil is wound on the yoke, and the coil after being energized can cause the yoke to generate a certain magnetic attraction force. The clamping assembly 4 is located in the accommodating cavity 2a, the clamping assembly 4 comprises a locking piece 41, one end of the clamping assembly 4 is fixed at one end, close to the clamping opening 2b, of the shell 2, and the moving piece 1 penetrates through the clamping opening 2b and is arranged in the clamping assembly 4 in a penetrating mode. The attraction assembly 5 is located in the accommodating cavity 2a, the attraction assembly 5 is provided with a pushing part and a releasing part, and the attraction assembly 5 can be attracted to the electromagnet assembly 3, so that the pushing part abuts against the locking part 41, and the locking part 41 locks the moving part 1. After the electromagnet assembly 3 is powered off, the attraction assembly 5 can move along the direction away from the electromagnet assembly 3, so that the release part is aligned with the locking piece 41, and the locking piece 41 releases the moving piece 1. That is, the electromagnetic locking mechanism has two states, namely, an energized locking state and a de-energized releasing state.
When the electromagnetic locking mechanism is in the power-off release state, the electromagnet assembly 3 is not powered, the locking piece 41 is aligned with the release part, and the moving piece 1 and the locking piece 41 are in a separation state. When the electromagnetic locking mechanism is electrified, the electromagnet assembly 3 is electrified, the magnet yoke inside the electromagnet assembly 3 has magnetic attraction force to attract the attraction assembly 5 to attract the electromagnet assembly 3, so that the clamping assembly 4 and the attraction assembly 5 generate relative motion to separate the locking piece 41 from the release part, the pushing part is aligned with the locking piece 41, the pushing part drives the locking piece 41 to lock the moving piece 1, and at the moment, the electromagnetic locking mechanism is converted into an electrified locking state.
When the electromagnetic locking mechanism is in an electrified locking state, the electromagnet assembly 3 is electrified, the attraction assembly 5 and the electromagnet assembly 3 are in an attraction state, the pushing part is aligned with the locking piece 41, and the locking piece 41 locks the moving piece 1. When the electromagnetic locking mechanism is powered off, the electromagnet assembly 3 is powered off, the magnet yoke in the electromagnet loses magnetic attraction, and the attracting assembly 5 is separated from the electromagnet assembly 3, so that the releasing part is aligned with the locking piece 41, the locking piece 41 releases the moving piece 1, and at the moment, the electromagnetic locking mechanism is converted into a power-off releasing state.
On the one hand, in the electromagnetic locking mechanism provided by the embodiment of the application, when an accident or power failure occurs, the electromagnet assembly 3 is powered off, the attraction assembly 5 moves along the direction away from the electromagnet assembly 3, the locking piece 41 of the clamping assembly 4 retreats to the release part of the attraction assembly 5, so that the moving piece 1 is released, and the moving piece 1 can move under the dead weight or external force. When the power-on locking state is carried out, the pushing part is abutted against the locking piece 41, the locking piece 41 locks the moving piece 1, and the locking piece 41 can bear large axial pulling force. On the other hand, each element component of the electromagnetic locking mechanism is positioned in the shell 2, the structure is compact, locking or releasing control can be realized only by switching on and off the electromagnet component 3, and the control is simple and convenient. On the other hand, after the electromagnetic locking mechanism is powered off, the stroke of the clamping assembly 4 for loosening the moving piece 1 is purely mechanical operation, so that the electromagnetic locking mechanism can be widely applied to the moving equipment of the existing nuclear reactor, and has high working reliability.
The connection between the electromagnet assembly 3 and the housing 2 and the connection between the clamping assembly 4 and the housing 2 are not limited, but exemplary connection methods include, but are not limited to, bolting, screwing, welding, cementing, etc.
In one embodiment, referring to fig. 1, the actuating assembly 5 includes an outer sleeve 53, a magnetizer 54, and an outer elastic member 55. The clamping assembly 4 is sleeved in the outer sleeve 53, and a pushing part and a releasing part are formed on the inner circumferential surface of the outer sleeve 53. The magnetizer 54 is fixedly connected with the outer sleeve 53. After the electromagnet assembly 3 is electrified, the magnetizer 54 can move along the direction approaching to the electromagnet assembly 3 and is attracted to the electromagnet assembly 3. That is, the magnetizer 54 provided on the outer sleeve 53 can be attracted by the yoke of the electromagnet assembly 3 after being electrified, so as to drive the outer sleeve 53 and the outer elastic member 55 connected with the outer sleeve 53 to move together in the direction of the electromagnet assembly 3, thereby aligning the pushing portion on the inner peripheral surface of the outer sleeve 53 with the locking member 41, and locking the moving member 1.
The outer elastic member 55 is connected with the outer sleeve 53, and after the electromagnet assembly 3 is powered off, the outer elastic member 55 can drive the outer sleeve 53 and the magnetizer 54 to move along the direction away from the electromagnet assembly 3. That is, the outer elastic member 55 has elasticity, and can provide an elastic force for moving the outer sleeve 53 and the magnetizer 54 in a direction away from the electromagnet assembly 3, after the magnetizer 54 is no longer subject to the magnetic attraction of the electromagnet assembly 3, the outer elastic member 55 can drive the outer sleeve 53 and the magnetizer 54 away from the electromagnet assembly 3, so that the releasing portion on the inner circumferential surface of the outer sleeve 53 is aligned with the locking member 41, and the moving member 1 is released.
The material of the magnetizer 54 is not limited, and the magnetizer 54 includes, but is not limited to, a mixed material containing a magnetically conductive metal such as iron, nickel, cobalt, or the like. Illustratively, in one embodiment, the magnetic conductor 54 is an armature, which is inexpensive and easy to manufacture.
The attachment of the magnetizer 54 to the outer sleeve 53 is not limited and exemplary attachment means include, but are not limited to, bolting, screwing, welding, cementing, etc.
The specific structure of the outer elastic member 55 is not limited, and exemplary outer elastic members 55 include, but are not limited to, springs, bellows, and the like.
The connection position between the magnetizer 54 and the outer sleeve 53 and the connection position between the outer elastic member 55 and the outer sleeve 53 are not limited, and connection nodes may be provided at appropriate positions such as the end portion of the outer sleeve 53, the circumferential wall, and the like. In an exemplary embodiment, referring to fig. 2, the outer sleeve 53 is formed with a flange 531, the outer elastic member 55 is connected to the flange 531, and the magnetizer 54 is fixedly connected to the flange 531. By providing the flange 531, the outer elastic member 55 and the magnetizer 54 can be more stably connected with the outer sleeve 53 by the flange 531 so as to transmit elastic force and magnetic attraction force.
In an embodiment, referring to fig. 1 and 2, the inner peripheral wall of the outer sleeve 53 is formed with a first annular surface 51, a second annular surface 52, and a third annular surface 56 connecting the first annular surface 51 and the second annular surface 52, the diameter of the first annular surface 51 is smaller than that of the second annular surface 52, the pushing portion is the first annular surface 51, and the releasing portion is the second annular surface 52. That is, the locking and releasing of the moving member 1 by the holder assembly 4 are both achieved by abutment of the inner peripheral wall of the outer sleeve 53 with the locking member 41. When the locking member 41 is aligned with the first annular surface 51, the first annular surface 51 pushes the locking member to move in a direction approaching the radial direction of the moving member 1, so that the locking member 41 locks the moving member 1. When the locking member 41 is aligned with the second annular surface 52, the second annular surface 52 has a larger diameter than the first annular surface 51, so that the second annular surface 52 provides space for the locking member 41 to release the moving member 1, and then the moving member 1 can push the locking member away from the moving member 1 in a radial direction under the action of external force, so that the locking member 41 releases the moving member 1.
In one embodiment, the inner peripheral wall of the outer sleeve 53 is formed with a first annular surface 51, a second annular surface 52, and a third annular surface 56 connecting the first annular surface 51 and the second annular surface 52, the diameter of the first annular surface 51 is smaller than that of the second annular surface 52, the pushing portion is the first annular surface 51, and the releasing portion is the third annular surface 56. Since the third annular surface 56 is connected between the first annular surface 51 and the second annular surface 52, the third annular surface 56 can have a transitional effect, and can also provide space for the locking member 41 to release the moving member 1.
In one embodiment, the first annulus 51 is a cylindrical surface. Because the first annular surface 51 is used for locking the moving part 1, the normal direction of the cylindrical surface is perpendicular to the axial direction of the moving part 1, the first annular surface 51 can only receive the acting force perpendicular to the axial direction of the moving part 1, and is not subjected to the component force along the axial direction of the moving part 1, so that the attraction force generated by the electromagnet assembly 3 can maintain the locking state only by overcoming the spring force of the outer elastic part 55, and the working reliability of the electromagnetic locking mechanism is improved.
In one embodiment, the second annulus 52 is a cylindrical surface. In this way, the outer sleeve 53 can be made compact.
In one embodiment, the third annular surface 56 is a conical surface. Illustratively, the conical surface of the third annulus 56 increases in diameter in a direction away from the first annulus 51 until the third annulus 56 connects with the second annulus 52. Thus, when the cooperation between the locking member 41 and the second annular surface 52 is switched to the cooperation between the locking member 41 and the first annular surface 51, the third annular surface 56 provided as a conical surface has a transitional effect, so that the switching between the power-on locking state and the power-off releasing state of the electromagnetic locking mechanism is smoother, and the locking mechanism is not easy to be blocked.
In one embodiment, referring to fig. 1 to 4, the electromagnet assembly 3 is fixedly connected to the upper end of the housing 2, the upper end of the outer elastic member 55 is connected to the upper end of the housing 2, and the lower end of the outer elastic member 55 is connected to the outer sleeve 53, or,
The electromagnet assembly 3 is fixedly connected with the upper end of the shell 2, the upper end of the outer elastic member 55 is connected with the outer sleeve 53, the lower end of the outer elastic member 55 is connected with the lower end of the shell 2, or,
The electromagnet assembly is fixedly connected with the lower end of the shell, the upper end of the outer elastic piece is connected with the upper end of the shell, the lower end of the outer elastic piece is connected with the outer sleeve, or,
The electromagnet assembly is fixedly connected to the lower end of the shell, the upper end of the outer elastic piece is connected with the outer sleeve, and the lower end of the outer elastic piece is connected with the lower end of the shell. That is, the electromagnet assembly 3 and the outer elastic member 55 may have at least four arrangements within the housing 2.
For example, referring to fig. 1 and 2, the electromagnet assembly 3 is fixedly connected to the upper end of the housing 2. The outer elastic member 55 is, for example, a compression spring, and abuts between the upper end of the housing 2 and the outer sleeve 53. When the electromagnet assembly 3 is electrified, the locking piece 41 is aligned with the pushing part, the outer elastic piece 55 is in a pressed state, and after the electromagnet assembly 3 is powered off, the outer elastic piece 55 can provide downward thrust along the axial direction of the moving piece 1 so as to align the locking piece 41 with the releasing part.
For example, referring to fig. 4, the electromagnet assembly 3 is fixedly connected to the upper end of the housing 2. The outer elastic member 55 is, for example, a tension spring, and abuts between the lower end of the housing 2 and the outer sleeve 53. When the electromagnet assembly 3 is electrified, the locking piece 41 is aligned with the pushing part, the outer elastic piece 55 is in a tension state, and after the electromagnet assembly 3 is powered off, the outer elastic piece 55 can provide a downward pulling force along the axial direction of the moving piece 1 so as to align the locking piece 41 with the releasing part.
For example, referring to fig. 3, the electromagnet assembly 3 is fixedly connected to the lower end of the housing 2. The outer elastic member 55 is, for example, a compression spring, and abuts between the lower end of the housing 2 and the outer sleeve 53. When the electromagnet assembly 3 is electrified, the locking piece 41 is aligned with the pushing part, the outer elastic piece 55 is in a pressed state, and after the electromagnet assembly 3 is powered off, the outer elastic piece 55 can provide an upward thrust along the axial direction of the moving piece 1 so as to align the locking piece 41 with the releasing part.
Similarly, the electromagnet assembly 3 may also be fixedly connected to the lower end of the housing 2. The outer elastic member 55 is, for example, a tension spring, and abuts between the upper end of the housing 2 and the outer sleeve 53. When the electromagnet assembly 3 is electrified, the locking piece 41 is aligned with the pushing part, the outer elastic piece 55 is in a tension state, and after the electromagnet assembly 3 is powered off, the outer elastic piece 55 can provide an upward pulling force along the axial direction of the moving piece 1 so as to align the locking piece 41 with the releasing part.
In one embodiment, referring to fig. 1, the clamping assembly 4 further includes a middle sleeve 42, the lower end of the middle sleeve 42 is fixed at one end of the housing 2 near the clamping opening 2b, the moving member 1 is inserted into the middle sleeve 42 through the clamping opening 2b, at least one locking groove 42a is formed on the circumferential wall of the middle sleeve 42, and the locking member 41 can move in the locking groove 42 a. On the one hand, the middle sleeve 42 can play a certain guiding role for the movement of the moving part 1. On the other hand, the locking groove 42a can play a limiting role on the locking member 41, and can ensure that the locking member can move only in the radial direction of the moving member 1.
In an exemplary embodiment, the middle sleeve 42 is provided with three locking grooves 42a uniformly arranged along the circumference of the middle sleeve 42, and the shape of the locking grooves 42a is adapted to the shape of the locking member 41, so as to facilitate the movement of the locking member 41 in the locking grooves 42 a.
In one embodiment, referring to fig. 1 and 5, the locking member 41 is a sphere, and the moving member 1 is formed with a ring groove 1a matching with the sphere. The ring groove 1a is an arc-surface ring groove 1a recessed towards the inside of the moving part 1, the arc radius of the arc surface is slightly larger than the radius of the sphere so as to be matched and locked with the sphere, and meanwhile, the axial movement gap of the moving part 1 when being locked can be controlled by adjusting the arc radius of the arc surface.
In one embodiment, the locking member 41 is a sphere, and the moving member 1 is formed with a groove that mates with the sphere. The influence of the grooves on the structural strength of the moving part 1 is small, so that the matching of the moving part 1 and the ball body is more compact. The groove is illustratively provided as a hemispherical surface, the sphere radius of the hemispherical surface is slightly larger than the sphere radius so as to be matched with the hemispherical surface for locking, and the axial play gap of the moving part 1 when the moving part 1 is locked can be controlled by adjusting the sphere radius of the hemispherical surface.
In an embodiment, referring to fig. 1 and 2, the electromagnetic locking mechanism further includes a stop assembly 6, an upper end of the stop assembly 6 is connected to the housing 2, and after the electromagnet assembly 3 is powered off, a lower end of the stop assembly 6 can push the moving member 1 to move out of the locking position and abut against the locking member 41. That is, after the electromagnet assembly 3 is powered off, the locking member 41 releases the moving member 1, and the moving member 1 may or may not be directly moved axially downward by the external force, and the moving member 1 may be pushed axially downward by the stop assembly 6 to the locking position. Therefore, on one hand, the stop component 6 can be abutted against the locking piece 41 after the locking piece 41 releases the moving piece 1, so that the probability of releasing the locking piece 41 is reduced, and the reliability of the electromagnetic locking mechanism is improved. On the other hand, the stop assembly 6 can provide partial pushing force for pushing the moving part 1 downwards in the axial direction, so as to facilitate the release of the moving part 1 after power failure.
Specifically, in one embodiment, referring to fig. 1 and 2, the stop assembly 6 includes an inner sleeve 61 and an inner resilient member 62. The inner sleeve 61 is sleeved in the clamping assembly 4. The inner elastic member 62 is connected at both ends to the inner sleeve 61 and the housing 2, respectively. The inner elastic member 62 has an elastic force to eject the inner sleeve 61 in the direction of the holding opening 2b so that the circumferential wall of the inner sleeve 61 can abut against the lock member 41 after the electromagnet assembly 3 is deenergized.
The specific structure of the inner elastic member 62 is not limited, and exemplary inner elastic members 62 include, but are not limited to, springs, bellows, and the like.
The connection position of the inner elastic member 62 is not limited, and connection nodes may be provided at appropriate positions of the end portion of the inner sleeve 61, the circumferential wall, and the like. For example, referring to fig. 1 and 2, the inner elastic member 62 abuts between the upper end of the housing 2 and the upper end of the inner sleeve 61.
In one embodiment, referring to fig. 2, the end of the inner sleeve 61 remote from the clamping opening 2b is formed with a limiting collar 611 for preventing the inner sleeve 61 from sliding out of the clamping assembly 4. Illustratively, the middle sleeve 42 is correspondingly provided with a step surface 421, and the limiting convex ring 611 and the step surface 421 mutually stop, so as to prevent the inner sleeve 61 from moving excessively to come out of the housing 2 after the moving member 1 moves out axially.
In an embodiment, referring to fig. 1,2 and 5, the electromagnetic locking mechanism further includes a guide tube 7 connected to the clamping opening 2b, the moving member 1 is disposed through the guide tube 7 in the clamping opening 2b, and the moving member 1 is formed with a guide convex ring 11. The guide convex ring 11 is connected with the inner peripheral wall of the guide tube 7 in a sliding way. The guide collar 11 ensures the coaxiality of the moving member 1 and the guide tube 7 when the moving member 1 moves in the guide tube 7.
For example, in one embodiment, referring to fig. 5, the annular surface of the guide convex ring 11 contacting the inner peripheral wall of the guide tube 7 is an arc surface protruding to the outer side of the moving member 1, so that the moving member 1 is smoothly inserted into the clamping opening 2 b. The end of the middle sleeve 42 near the holding opening 2b and the mover 1 are provided with chamfers to facilitate insertion of the mover 1 into the middle sleeve 42.
In another aspect, the application provides a movement apparatus for a reactor, comprising an electromagnetic locking mechanism as described in any one of the preceding claims. The electromagnetic locking mechanism provided by the application has smaller volume and higher reliability, and can be used as key equipment to be applied to movement equipment of a reactor.
The foregoing is merely illustrative of embodiments of the present application, and the present application is not limited thereto, and any person skilled in the art will readily recognize that variations or substitutions are within the scope of the present application. Therefore, the protection scope of the present application shall be subject to the protection scope of the claims.
