Detailed ways

The clutch energy storage device of the present invention will be further described below in conjunction with the accompanying drawings. It should be noted here that the description of the following embodiments is used to help understand the utility model, but does not constitute a limitation to the utility model. In addition, the technical features involved in the various embodiments of the present invention described below can be combined with each other as long as they do not constitute conflicts with each other.

This embodiment discloses a clutch energy storage device, which is used to store potential energy for the energy release mechanism of a circuit breaker or switch, and it is not limited to the field of circuit breakers or switches, but can also be used in other devices that require manual and electric energy storage at the same time middle. The energy release mechanism is generally a compression spring or a torsion spring in a circuit breaker or switch. The energy release mechanism can store elastic potential energy after being applied, so that the energy release mechanism is triggered when the circuit breaker or switch needs to be closed or opened. Release the stored potential energy to achieve the purpose of automatic closing or automatic opening.

Referring to Fig. 1, the clutch energy storage device of the present embodiment includes a shaft 10 that relies on rotation to store energy for the energy release mechanism, a manual drive mechanism 20 and an electric drive mechanism 30 for driving the rotation of the shaft 10, and the manual drive mechanism The setting of 20 ensures that the circuit breaker or switch can still obtain the potential energy of automatic closing and opening when the electric drive mechanism 30 fails. Wherein, a gear set 12 is arranged in linkage on the shaft 10, and when the manual drive mechanism 20 or the electric drive mechanism 30 drives the gear set 12, the gear set 12 can drive the shaft 10 to rotate forward, and store potential energy for the energy release mechanism. It should be noted that the forward direction refers to the direction in which the shaft 10 rotates when the potential energy mechanism stores potential energy, and the reverse direction refers to the direction in which the shaft 10 rotates when the potential energy mechanism releases potential energy.

Referring to Fig. 1 and Fig. 7, it also includes the first one-way clutch mechanism 50. After the manual drive mechanism 20 or the electric drive mechanism 30 has finished storing energy, in order to enable the energy release mechanism to release energy, it will not apply a holding force to the shaft 10. Torque, in the unused state, the potential energy accumulated by the energy release mechanism will be lost along with the recovery deformation, and in this embodiment, the first one-way clutch mechanism 50 is locked by means of locking when the gear set 12 produces a reverse rotation tendency. Prevent the reverse rotation of the gear set 12, so that the energy release mechanism cannot recover from deformation, prevent the potential energy loss of the energy release mechanism, ensure the opening and closing speed of the circuit breaker or switch, and improve the opening and closing sensitivity.

The setting method of the first one-way clutch mechanism 50 in this embodiment will be described in detail below with reference to FIG. 6:

The first one-way clutch mechanism 50 includes a plurality of gear teeth arranged on the outer circumference of the gear set 12, and a non-return part 40. When the gear set 12 drives the gear teeth to rotate forward, the non-return part 40 moves intermittently in multiple Between the two gear teeth, the non-return part 40 locks the gear teeth of the gear set 12 to prevent the gear set 12 from rotating reversely when the gear set 12 has a reverse rotation tendency.

Further, the non-return part 40 includes a fixed shaft 43, a non-return pawl 41 disposed on the fixed shaft 43, and a pawl bias that provides a biasing force for the non-return pawl 41 to the gear teeth. 42, the non-return pawl 41 has an arc-shaped sliding wall matching the streamline shape of the gear teeth in the direction of forward rotation. In actual use, when the gear set 12 rotates in the forward direction, the biasing force of the biasing member 42 causes the end of the pawl 41 with the arc-shaped sliding wall to protrude between the teeth, and the pawl 41 is pushed apart during the gear rotation. , so that the pawl 41 enters between the next gear teeth; when the gear set 12 has a movement tendency of reverse rotation, since the arc-shaped sliding wall of the pawl 41 forms an acute angle with the direction of motion of the gear set 12, The pawl 41 can stop the gear set 12 from continuing to rotate.

The linkage setting method of the gear set 12 and the shaft 10 will be described in detail below in conjunction with Fig. 2 and Fig. 5:

There are many ways to set the gear set 12 and the shaft 10 in linkage, for example: the gears in the gear set 12 are centered on the shaft 10 and fixed on the shaft 10 through a fixed structure; or the gear set 12 is directly integrated with the shaft 10 The setting method of forming; or the setting method in which gear teeth are formed on the shaft 10, and the gear set 12 meshes with the gear teeth; and the gear set 12 can also be set by the third one-way clutch mechanism 70 described later The arrangement on the shaft 10; it can also be any combination of the above arrangements. The setting of the gear set 12 only needs to ensure that the shaft 10 can be driven to rotate when the gear set 12 is driven. Those skilled in the art can select the gear set 12 and the shaft according to the above description combined with common knowledge in the field under the condition of meeting the design requirements. The specific setting method of 10 linkage is used as an alternative, and will not be repeated here.

Referring to FIG. 1 , the gear set 12 includes a first gear 121 and a second gear 122 .

As a preferred implementation manner, referring to FIG. 2 , the first gear 121 is integrally formed on the shaft 10 . In the embodiment shown in FIG. 2 , the gear on the manual driving mechanism 20 meshes with the first gear 121 , which can drive the shaft 10 to rotate forward, and store energy for the energy release mechanism. Since the first gear 121 is relatively fixed to the shaft 10, the first one-way clutch mechanism 50 preferably acts on the first gear 121, thereby preventing the reverse rotation of the shaft 10 by locking the first gear 121 from reverse rotation, so as to It is guaranteed that the potential energy stored by the energy release mechanism will not be lost. Although not shown in the drawings, as a modification of the embodiment shown in FIG. 2 , the first gear 121 can also mesh with the electric driving mechanism 30 , and it rotates forwardly driven by the electric driving mechanism 30 .

As a modified embodiment of the first gear 121, the first gear 121 can also be fixedly mounted on the shaft 10 through a connection structure, for example, the connection structure can be a threaded connection or a fixed pin, etc., so that the first gear 121 and the shaft 10 remains relatively constant.

Below in conjunction with Fig. 1, Fig. 2 describe in detail the setting mode of manual drive mechanism 20 in the present embodiment:

In this embodiment, the manual drive mechanism 20 includes a gear shaft 21, and the gear end of the gear shaft 21 meshes with the gear set 12. As a preferred embodiment, the gear end of the gear shaft 21 meshes with the first gear 121, and the gear end of the gear shaft 21 meshes with the first gear 121. The shaft end of the shaft 21 is connected with the rotary handle 211 through the second one-way clutch mechanism 60 .

3 and 4, the second one-way clutch mechanism 60 includes a shaft sleeve 61 with internal teeth, the shaft sleeve 61 is sleeved on the shaft end of the gear shaft 21, and the gear shaft 21 is located at the position where the shaft sleeve 61 is mated. A housing space 64 is formed, the housing space 64 is a radial channel on the gear shaft 21, two sliding pawls 62 are arranged at both ends of the radial channel, and the elastic member 63 is arranged between the two sliding pawls 62, The elastic biasing force of the elastic member 63 drives the two sliding pawls 62 to engage with the internal teeth of the sleeve 61 . When the shaft sleeve 61 rotates counterclockwise in the state shown in Figure 4, the sliding pawl 62 will intermittently move between the internal teeth of the shaft sleeve 61; When the hour hand rotates, the sliding pawl 62 will remain relatively fixed with the shaft sleeve 61, while the sliding pawl 62 will remain relatively fixed with the gear shaft 21, so rotating the shaft sleeve 61 can drive the gear shaft 21 to rotate, and further drive the shaft 10 to rotate. able.

The setting of the above-mentioned second one-way clutch mechanism 60 makes the clutch energy storage device of this embodiment allow the rotary handle 211 to rotate when the manual drive mechanism is used to drive and store energy, and the shaft 10 will not be reversely rotated. Specifically, in actual use, when the staff pulls down the rotary handle 211, the gear shaft 21 is driven to move, and then the shaft 10 can be driven to rotate forward to store energy. After that, the staff does not continue to apply force to the rotary handle 211, Because the second one-way clutch mechanism 60 can allow the shaft sleeve to rotate in reverse with respect to the shaft end of the gear shaft 21, the rotary handle 211 does not transmit torque to the gear shaft 21 during the return process, and thus does not drive the shaft 10 to reverse.

In addition, the setting of the second one-way clutch mechanism 60 can also prevent the rotary handle 211 from rotating during the electric energy storage process, so that the electric energy storage process does not affect the manual drive mechanism. The following describes the state of the manual drive mechanism 20 when the electric drive mechanism 30 is storing energy with reference to FIGS. 2-4 :

Set the clockwise direction in Figure 2 as the positive direction, that is, the shaft 10 rotates clockwise to store energy, and rotates counterclockwise to release potential energy. In FIG. 2 , the electric drive mechanism 30 drives the second gear 122 to rotate to drive the shaft 10 to rotate forward. During the process of the shaft 10 rotating forward, it drives the first gear 121 to rotate forward. At this time, it meshes with the first gear 121. The gear end of the gear shaft 21 is driven to rotate in reverse. Referring to the schematic cross-sectional view of the second one-way clutch mechanism 60 shown in FIG. 3 and the perspective view of the second one-way clutch mechanism 60 shown in FIG. Compression and expansion, and intermittent movement between the internal teeth of the sleeve 61, so that the gear shaft 21 forms an idle rotation relative to the rotary handle 211, so the rotary handle 211 will not move, so that the electric energy storage process will not affect the manual drive mechanism 20.

Moreover, with the setting of the above-mentioned second one-way clutch mechanism 60, the sliding pawl 62 can be hidden in the accommodation space 64 in the gear shaft 21. Compared with the general one-way clutch structure, the second one-way clutch mechanism of this embodiment 60 is simpler in structure, takes up less space, and further reduces the size of the device. Since the second one-way clutch mechanism 60 has a simple structure and a small volume, it is suitable for installation in mechanisms with limited space but low precision requirements. Obviously, the second one-way clutch mechanism 60 can also use other forms of clutch mechanisms, which will not be repeated here.

As a modified implementation of the above-mentioned second one-way clutch mechanism 60, the number of sliding pawls 62 can also be set to three, four or more; and the direction of the sliding pawls 62 is not limited to that shown in FIG. As shown, it protrudes in the radial direction, and it can also protrude obliquely at a certain angle with the radial direction. It is only necessary to ensure that the sliding pawl 62 can extend into the interior of the sleeve 61 under the action of the elastic member 63. between the teeth.

With reference to Fig. 1, the free end of the rotary handle 211 in the present embodiment is connected with reset member 212 (here is extension spring), and the other end of reset member 212 is fixedly connected on the fixed position, and the staff can pull all the handles in pendulum like this. The rotary handle 211, the reset member 212 drives the rotary handle 211 to reset, and during the reset process, due to the setting of the second one-way clutch mechanism 60, the rotary handle 211 is idling relative to the gear shaft 21.

In actual use, the clutch energy storage device of this embodiment is often installed at a higher position on the utility pole. In the past, workers had to climb up the utility pole and drive the rotary handle 211 in a single direction to use the manual drive mechanism 20 . If the length of the rotary handle 211 is short, the torque that needs to be applied by the staff during the rotation will be very large; if the length of the rotary handle 211 is long, it will be difficult for the staff to complete the rotation of the entire circle. Very difficult.

Referring to Figures 1 and 2, in the clutch energy storage device of this embodiment, the staff can hang on the rotary handle 211 through a tool hook, and pull the rotary handle 211 in a pendulum manner on the ground to complete the manual energy storage action, effectively reducing the staff's effort. Labor intensity, compared with the existing manual energy storage mechanism is also safer; secondly, when the sliding pawl 62 is reset under the action of the reset member 212, because it moves intermittently between the inner teeth of the shaft sleeve 61, it will give the ground The vibration feedback of the staff enables the staff to know whether the manual energy storage is successful.

Below in conjunction with Fig. 2, Fig. 5, Fig. 6 describe in detail the arrangement mode of the electric driving mechanism 30 in this embodiment:

In a preferred embodiment shown in FIG. 5 , the electric drive mechanism 30 includes an output motor 31 and a gear transmission mechanism 32 driven by the output motor 31 to rotate, and the gear transmission mechanism 32 meshes with the second gear 122, By driving the shaft 10 to rotate, the output shaft of the output motor 31 drives the gear transmission mechanism 32 to rotate, and the gear transmission mechanism 32 meshes with the second gear 122 to drive the shaft 10 to rotate and store potential energy for the energy release mechanism. As an alternative embodiment, the output motor 31 can directly form gear teeth meshing with the second gear 122 on its output shaft, so as to drive the shaft 10 to rotate.

Further, a third one-way clutch mechanism 70 is also provided between the second gear 122 and the shaft 11, so that the second gear 122 can transmit torque to the shaft 10 when rotating in the forward direction, and drive the shaft 10 to rotate; When the second gear 122 rotates in the opposite direction, it idles relative to the shaft 10 and cannot transmit torque. Since the third one-way clutch mechanism 70 is used to connect the shaft 10 and the second gear 122, it pays more attention to the transmission of torque compared with the second one-way clutch mechanism 60, so the third one-way clutch mechanism 70 selects and second one-way clutch mechanism Clutch mechanism 60 is a different roller type one-way clutch mechanism. Specifically, referring to FIG. 2, it includes a chute 71 formed on the inner ring of the second gear 122 at intervals, a roller 72 arranged in the chute 71, and a roller acting on the roller 72. The number of sub-biasing parts 73 and rollers 72 is usually 6-8. During operation, if the second gear 122 rotates counterclockwise with respect to the shaft 10 as shown in FIG. 2 , the roller 72 will move toward the big end in the chute 71 with the cam profile and compress the spring. At this time, the one-way clutch does not lock up, and the outer ring is allowed to rotate; on the contrary, if the second gear 122 rotates clockwise relative to the shaft 10 as shown in Figure 2, the second gear 122 and the shaft 10 will Locking, that is to say, turning the second gear 122 clockwise can drive the shaft 10 to rotate to complete the electric energy storage process.

It should be noted that the gear transmission mechanism 32 preferably uses a multi-stage reduction gear set, so that the high-speed torque output by the output motor 31 can be converted into a low-speed torque, thereby making the energy storage process of the electric drive mechanism 30 more stable.

The clutch energy storage device of this embodiment also includes a casing 80, the main structure of which is a vertical mounting plate, and the manual drive mechanism 20 and the shaft 10 are arranged on the same side of the casing 80 The drive motor 31 in the electric drive mechanism 30 is arranged on the other side of the casing 50 , and the output shaft of the drive motor 31 passes through the casing 80 and is connected to the gear transmission mechanism 32 . The advantage of such arrangement is that the manual drive mechanism 20 , the electric drive mechanism 30 and the casing 80 can be installed on the same installation surface, so that the reference is unique and easy for installation and positioning. At the same time, it also ensures that the structure of the clutch energy storage device in this embodiment is relatively compact, which helps to improve the miniaturization of the equipment and reduce the installation space occupied by the equipment.

Specifically, one end of the shaft 10 is fixedly mounted on the casing 80; the non-return pawl 41 is pivotally disposed on the fixed shaft 43 formed on the casing 50, and the fixed shaft 43 is connected to the shaft 10. Extending in the same direction; the pawl biasing member 42 is a torsion spring sleeved on the fixed shaft 43 .

In addition, as shown in FIG. 2 , the clutch energy storage device of this embodiment also includes a casing covering the manual drive mechanism 20 and the electric drive mechanism 30 , which is mainly used to protect the equipment from environmental factors.

Apparently, the above-mentioned embodiments are only examples for clear description, and are not intended to limit the implementation. For those of ordinary skill in the art, other changes or changes in different forms can be made on the basis of the above description. It is not necessary and impossible to exhaustively list all the implementation manners here. And the obvious changes or variations derived therefrom are still within the scope of protection of the utility model.
