That is, the wave power unit 1 is mainly composed of a housing 10, an internal bracket 11, a suspension body 12 and an output 14, wherein the suspension body 12 is disposed in an internal cavity 100 of the housing 10, and the internal bracket 11 and a suspension support 13 are further disposed in the internal cavity 100 of the housing 10. The inner bracket 11 is further provided with a first guide rail 110 and a second guide rail 111, wherein the first guide rail 110 is disposed on the inner bracket 11 (e.g., four corners of the inner bracket) and is disposed along a height direction of the inner bracket 11, the suspension body 12 is provided with a lifting roller 120, the lifting roller 120 is matched with the first guide rail 110 and is used for guiding the suspension body 12 to move in the height direction of the inner bracket 11, so that the suspension body 12 can move in the housing 10 according to a set path, collision or friction between the suspension body 12 and the inner bracket 11 or an inner wall of the housing 10 is avoided, and it is ensured that the suspension body 12 can stably and reliably move in the housing 10 relative to the housing 10.
Further, in the present embodiment, the suspension body 12 is provided with the suspension support portion 13, the suspension support portion 13 is disposed along the width direction of the housing 10, and when the suspension body 12 moves relative to the housing 10 under the guidance of the movement of the first guide rail 110, the suspension body 12 can drive the suspension support portion 13 to move along the second guide rail 111 along the width direction of the housing 10, and can support the suspension body 12. That is, the suspension body 12 and the suspension support portion 13 are linked to each other. During the wave lifting, the suspension body 12 and the housing 10 are caused to move relative to each other due to inertia and gravity. During the relative movement of the suspension body 12 and the housing 10, under the action of the second guide rail 111, the suspension support portion 13 can not only support the suspension body 12, but also move in the width direction of the housing 10, specifically, under the action of the second guide rail 111, the suspension support portion 13 can generate an elastic acting force on the suspension body 12, and the elastic acting force can keep the suspension body 12 in stress balance at a corresponding position of the movement stroke of the suspension body 12, so that the suspension support portion 13 can form a supporting force on the suspension body 12.
When the housing 10 is jacked up by the wave rising, the suspension body 12 moves downward together with the suspension support portion 13 due to the gravity, and at the same time, the suspension support portion 13 can move in the width direction of the housing 10 under the limitation of the second guide rail 111, the suspension support portion 13 can be compressed, the kinetic energy of the suspension body 12 can be stored, and at the same time, the elastic acting force generated by the suspension support portion 13 can form a supporting force for the suspension body 12 to support the suspension body 12. When the waves descend, due to the dual functions of gravity and inertia, the suspension body 12 can drive the suspension support portion 13 and the shell 10 to move upwards relatively after moving upwards to the limit position, the suspension support portion 13 can be released, and the output portion 14 is driven to rotate continuously, so that stored kinetic energy is converted into torque output by the output portion 14, and the conversion efficiency of the suspension body 12 on the kinetic energy is improved. Meanwhile, the suspension support part 13 is arranged along the width direction of the shell 10, so that the space occupied by the suspension support part 13 in the shell 10 can be reduced, the whole device can be made smaller, and the miniaturization development of the wave power generation device 1 is facilitated.
Meanwhile, in the present embodiment, the inner cavity 100 of the housing 10 is closed, and the suspension body 12, the second guide rail 111 and the suspension support 13 are all disposed in the inner cavity 100 of the housing 10 and are not in contact with the water outside the housing 10, so that the components in the inner cavity 100 of the housing 10 can be prevented from being corroded by the water, and the service life of the whole device is prolonged. Specifically, in this embodiment, the housing 10 may be a stainless steel housing, a resin housing with high strength and high corrosion resistance, or a housing made of other types of high-strength and high corrosion resistance materials, which is not limited in this respect, and may be reasonably selected and designed according to actual needs as long as the characteristics of high strength and high corrosion resistance can be achieved.
Adopt above-mentioned technical scheme, through using inner chamber confined casing to will hang parts such as body and set up in the inner chamber, can prevent that the part in the inner chamber from being corroded by the water, the security is high, has promoted the life of whole device. Meanwhile, the first guide rail and the suspension supporting part are arranged between the inner support and the suspension body, so that the suspension body and the inner support can be prevented from being collided or rubbed, the suspension body can stably and reliably move relative to the shell in the inner support, the kinetic energy generated in the relative movement process of the suspension body and the shell can be stored in the suspension supporting part, the stored kinetic energy is continuously converted into the torque output by the output part, and the conversion efficiency of the suspension body on the kinetic energy is improved.
Further, referring to fig. 5 in combination with fig. 1 to 4, in the present embodiment, in the height direction (as shown in the Z direction in fig. 1 to 5), in the stationary state, the suspension body 12 is at the midpoint position (as shown in the C position in fig. 5) of the first guide rail 110, and in the moving state, the suspension body 12 can move up and down along the first guide rail 110 through the midpoint position. That is, in the rest state, the suspension body 12 can be brought to the midpoint position of the first rail 110 due to the action of the gravity of the suspension body 12 itself on the one hand and by adjusting the state of the suspension support portion 13 on the other hand. When the suspension body 12 is at the midpoint position of the first guide rail 110, the suspension body 12 can pass through the midpoint position regardless of whether the suspension body 12 moves upward or downward along the first guide rail 110, and the power is continuously output through the output portion 14, thereby improving the conversion efficiency of the kinetic energy of the suspension body 12.
Further, in the present embodiment, the second guide rail 111 includes a hyperbolic rail disposed along the height direction (as shown in the Z direction in fig. 1 to 5) of the inner frame 11. That is, the suspension body 12 moves relative to the housing 10 along the hyperbolic sliding track in the housing 10, so that not only the collision or friction between the suspension body 12 and the inner wall of the housing 10 can be avoided, but also the suspension body 12 can be ensured to move relative to the housing 10 stably and reliably in the housing 10. And the shell 10 is driven by the wave to move up and down, under the action of gravity and the suspension support part 13, the suspension body 12 and the shell 10 generate relative motion, the suspension body 12 can compress and release the suspension support part 13 along a hyperbolic sliding rail, so that the linear response relation between the suspension support part 13 and the suspension body 12 is changed into an arc response relation along a hyperbolic curve, the stroke of the suspension body 12 under the same inertia acceleration is increased, the gravity response sensitivity of the suspension body 12 is increased, the suspension body 12 can also generate relative motion with the shell 10 under the condition of small wave, and the conversion efficiency of the suspension body 12 to kinetic energy is improved.
In other embodiments, the second guide rail may also have other shapes, such as a parabolic slide rail, an involute slide rail, and the like, which is not limited in this respect, and may be reasonably arranged according to actual needs, as long as it can improve the gravity response sensitivity of the suspension body and increase the conversion efficiency of the suspension body to kinetic energy.
It should be noted that the specific structure of the suspension support portion is not limited in the present invention, and may be reasonably configured according to actual needs, for example, the suspension support portion may include an elastic component (such as a spring, a spring plate, etc.), or may include a compressed gas (such as an airbag, an air cushion, etc.), as long as the kinetic energy generated during the movement of the suspension body can be stored and released.
Specifically, referring to fig. 1-4, in the present embodiment, the suspension support 13 includes a pressing plate 130 and an elastic supporting member 131, the elastic supporting member 131 is disposed above the suspension body 12 through a supporting frame 132, and the pressing plate 130 is disposed at two ends of the elastic supporting member 131, and can compress or release the elastic supporting member 131 along the width direction of the housing 10 under the driving of the suspension body 12 and the action of the second guiding rail 111.
That is to say, the suspension support portion 13 mainly comprises a pressing plate 130 and an elastic supporting member 131, wherein the suspension body 12 is provided with a supporting frame 132, the elastic supporting member 131 is arranged on the supporting frame 132, the pressing plate 130 is arranged at two ends of the elastic supporting member 131, and the elastic supporting member 131 can be compressed or released along the width direction of the housing 10 under the driving of the suspension body 12 and the action of the second guide rail 111, so as to store and release the kinetic energy of the suspension body 12.
When the wave rises to jack up the housing 10, the suspension body 12 moves downward together with the suspension support 13 due to gravity, and at the same time, the pressing plate 130 can move in the width direction of the housing 10 under the restriction of the second guide rail 111, and the elastic support 131 can be compressed, storing the kinetic energy of the suspension body 12 in the elastic support 131. When waves descend, due to the dual action of gravity and inertia, the suspension body 12 can drive the suspension support portion 13 and the housing 10 to move upwards after moving upwards to the limit position, at this time, the pressing plate 130 loosens the elastic support member 131, the kinetic energy stored in the elastic support member 131 can be released, the energy released by the elastic support member 131 can continuously drive the suspension body 12 to move, and then the continuous driving output portion 14 of the suspension body 12 rotates, so that the stored kinetic energy is converted into the torque output by the output portion 14, and the conversion efficiency of the suspension body 12 to the kinetic energy is improved.
More specifically, referring to fig. 1-4, in the present embodiment, the elastic supporting element 131 is a pressure spring or a spiral spring for storing kinetic energy generated during the relative movement between the suspension body 12 and the housing 10, and the elastic supporting element 131 is sleeved on the supporting frame. When the elastic support 131 is a pressure spring, it can be selected to have a suitable elastic coefficient, and two ends of the elastic support are respectively abutted against the pressing plate 130. During the relative movement between the suspension body 12 and the housing 10, the pressure spring can be compressed by the pressure plate 130, so as to store the kinetic energy. In the process of restoring the suspension body 12 to the equilibrium position, the pressure spring can release the stored kinetic energy to drive the suspension body 12 to drive the output part 14 to rotate.

In the process that the suspension body 12 drives the transmission belt 140 to move, the transmission belt 140 can transmit power to the input shaft 142A, the input torque can enable the input shaft 142A to rotate, when the input torque is in a forward direction, that is, the input shaft 142A rotates in the forward direction, at this time, the one-way bearing 156 of the first driving gear 150 is in a locked state, that is, the input shaft 142A drives the first driving gear 150 to rotate synchronously through the one-way bearing 156, and the one-way bearing 156 of the second driving gear 152 is in a free state, that is, the second driving gear 152 idles on the input shaft 142A, the first driving gear 150 drives the output shaft 142B to rotate synchronously through engaging the driven gear 151 to output reverse torque outwards, and the output shaft 142B drives the generator 144 to work, so that the kinetic energy of the suspension body 12 is converted into electric energy of the generator 144.
