Description

Technical Field

[0001] The present invention relates to the technical field of wave power generation, and in particular to a vertical pole floating box reciprocating wave generator. Background Art

[0002] Electric energy is one of the main energy sources we need to use today. Whether it is household appliances in daily life or large engineering equipment in projects, they all need to be driven by electric energy. There are various ways to generate electric energy. The traditional power generation method is generally thermal power generation, which generates electric energy by burning materials such as coal. However, thermal power generation causes relatively serious environmental pollution. Therefore, the development of clean energy is of top priority. There are also various types of clean energy, such as wind energy, solar energy, tidal energy, etc. Among them, tidal energy utilizes the waves generated by the earth's tidal force to generate electricity through the waves. There are also various types of tidal energy generators. The vertical pole floating box reciprocating wave generator is one of them. It mainly drives the floating box to move up and down by seawater, and the floating box drives the vertical pole to reciprocate up and down to generate electricity through this movement.

[0003] In the prior art, during the working process, electricity is generated by the up-and-down reciprocation of the floating box. By using the traditional meshing method of a rack and a gear to convert the vertical movement into a rotational movement, the gear will also rotate reciprocally accordingly, so that the generator rotates reciprocally to generate alternating current. In order to store the electric energy, it is also necessary to process it, or only use the electric energy generated in one direction, resulting in the kinetic energy of the waves not being well utilized.

[0034] To make the objectives, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are some, but not all, of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0035] A vertical pole floating box reciprocating wave generator, in combination with Figures 1-8 as shown, includes: a sleeve 1 that fluctuates with the waves, a plug rod 2 fixed to the seabed, a generator 3, and a driving device that drives the generator 3 to rotate in the same direction to generate electricity; the sleeve 1 is sleeved on the plug rod 2 and moves axially along the plug rod 2, and the generator 3 and the driving device are arranged inside the sleeve 1;

[0036] The driving device includes a phase-changing component and a transmission component. The phase-changing component includes: a positioning shaft 41, a first ratchet mechanism 42, a second ratchet mechanism 43, a first rack 44, and a second rack 45. The positioning shaft 41 is rotatably arranged on the plug rod 2. The first ratchet mechanism 42 and the second ratchet mechanism 43 are coaxially arranged on the positioning shaft 41. The idling directions of the first ratchet mechanism 42 and the second ratchet mechanism 43 are set to be the same. The outer ring 421 of the first ratchet mechanism 42 and the second ratchet mechanism 43 is provided with an external gear ring. The first rack 44 and the second rack 45 are arranged on the sleeve 1. The first rack 44 meshes with the external gear ring of the first ratchet mechanism 42, and the second rack 45 meshes with the external gear ring of the second ratchet mechanism 43. The first rack 44 and the second rack 45 are located on both sides of the positioning shaft 41. The positioning shaft 41 transmits the rotational motion to the generator 3 through the transmission component.

[0037] When the first rack 44 and the second rack 45 rise, the first ratchet mechanism 42 drives the positioning shaft 41 to rotate, and the second ratchet mechanism 43 idles.

[0038] When the first rack 44 and the second rack 45 descend, the first ratchet mechanism 42 idles, and the second ratchet mechanism 43 drives the positioning shaft 41 to rotate in the same direction.

[0039] In this application, by setting the phase-changing component, and through the cooperation of the first ratchet mechanism 42 and the second ratchet mechanism 43 with the first rack 44 and the second rack 45, it is realized that no matter whether the sleeve 1 moves upward or downward, the generator 3 will rotate in the same direction to generate electricity, without the need to process the generated electric energy, making full use of the kinetic energy of the floating and sinking of the sleeve 1, and thus making more full use of the kinetic energy of the ocean waves.

[0040] Specifically, the bottom ends of the first rack 44 and the second rack 45 are fixed to the bottom of the sleeve 1 by screws, and the top ends are fixed to the top of the sleeve 1 by screws. The first rack 44 and the second rack 45 move synchronously with the lifting and lowering of the sleeve 1.

[0041] Preferably, the transmission component includes: a driving gear 51 coaxially arranged on the positioning shaft 41, a rotating shaft 52 arranged on the plug rod 2, and a driven gear 53 coaxially fixed on the rotating shaft 52. The driving gear 51 meshes with the driven gear 53, and the rotating shaft 52 drives the generator 3. The first ratchet mechanism 42 and the second ratchet mechanism 43 of the phase-changing component drive the positioning shaft 41 to rotate in the same direction. Thus, the positioning shaft 41 drives the driving gear 51 to rotate, the driving gear 51 then drives the driven gear 53 and the rotating shaft 52 to rotate synchronously, and finally the rotating shaft 52 drives the input shaft of the generator 3 to rotate through a coupling to generate electricity.

[0042] Preferably, the transmission component further includes a transition shaft 54 and a transition gear 55. The transition shaft 54 is arranged on the insertion rod 2, and the transition gear 55 is coaxially and fixedly arranged on the transition shaft 54. The driving gear 51 meshes with the transition gear 55, and the transition gear 55 meshes with the driven gear 53. By arranging the transition shaft 54 and the transition gear 55, the center distance between the rotating shaft 52 and the positioning shaft 41 can be increased, which is beneficial to the arrangement of the generator 3.

[0043] Specifically, the bottom end of the insertion rod 2 is inserted into the mud and stones on the seabed for fixation, and the top end penetrates through the sea surface. A bracket 21 is fixedly arranged at its top end through a flange structure. The bracket 21 vertically arranges the rotating shaft 52, the transition shaft 54, and the positioning shaft 41 from top to bottom.

[0044] Preferably, a flywheel 46 is further arranged on the positioning shaft 41, and the positioning shaft 41 drives the flywheel 46 to rotate. Through the mutual cooperation of the first ratchet mechanism 42, the second ratchet mechanism 43, and the flywheel 46, the smooth rotation of the positioning shaft 41 can be realized. The sea waves cause the sleeve 1 to float and sink. The first rack 44 and the second rack 45 move up and down with the sleeve 1, and then drive the positioning shaft 41 to rotate through the first ratchet mechanism 42 and the second ratchet mechanism 43, applying torque to the flywheel 46; when the sea waves cause the sleeve 1 to float and sink again, even if the speed at which the sea waves drive the positioning shaft 41 to rotate is lower than the speed at which the flywheel 46 rotates this time, the ratchet mechanism will produce idling relative to the positioning shaft 41, enabling the positioning shaft 41 to rotate under the inertia of the flywheel 46; ensuring that the rotation speed of the positioning shaft 41 is more stable, so that the generator 3 generates electricity more smoothly. Moreover, after the sea waves stop, the flywheel 46 continues to rotate for a period of time under its own inertia, thereby increasing the working duration of the generator and making more full use of the kinetic energy of the sea waves.

[0045] Specifically, both ends of the positioning shaft 41 penetrate through the bracket 21. The first ratchet mechanism 42, the second ratchet mechanism 43, and the driving gear 51 are located on one side of the bracket 21, and the flywheel 46 is located on the other side of the bracket 21 to ensure as even a weight distribution as possible and avoid the sleeve 1 generating a large lateral force impact on the insertion rod 2 under the action of the sea waves.

[0046] Specifically, an annular cavity 14 is machined from the top end to the bottom end of the sleeve 1. The annular cavity 14 is located between the inner and outer walls of the sleeve 1 and is arranged around the axis of the sleeve 1. First and second long holes 15 and 16 that penetrate the inner and outer walls of the sleeve 1 are also machined on the side wall of the sleeve 1, and the first and second long holes 15 and 16 are arranged oppositely. An inner sleeve 7 is provided in the annular cavity 14. The inner and outer diameters of the inner sleeve 7 match the large and small diameters of the annular cavity 14. A sealing ring is installed outside the inner sleeve 7 to seal with the inner wall of the annular cavity 14. The length of the inner sleeve 7 is less than the length of the annular cavity 14 and greater than the lengths of the first and second long holes 15 and 16. The length of the inner sleeve 7 ensures that within the stroke of the sleeve 1, the inner sleeve 7 blocks the first and second long holes 15 and 16. The lengths of the inner sleeve 7, the annular cavity 14, and the sleeve 1 ensure adaptation to the stroke of the movement of the sleeve 1. Oppositely arranged first and second mounting holes are formed in the inner sleeve 7. One end of the positioning shaft 41 is rotatably connected to the first mounting hole through the first long hole 15, and the other end passes through the second long hole 16 and the second mounting hole and is fixedly connected to the flywheel 46, enabling the flywheel 46 to be arranged outside the sleeve 1, and further enabling the size of the flywheel 46 to be increased. Rotating sealing structures are installed at both ends of the positioning shaft 41 at the first and second mounting holes for sealing, such as dynamic sealing rings and labyrinth seals. When the sleeve 1 floats and sinks, the inner sleeve 7 remains vertically stationary under the restriction of the positioning shaft 41, and the sleeve 1 slides relative to the inner sleeve 7. The sealing structure provided between the inner sleeve 7 and the annular cavity 14 can ensure the sealing at the positions of the first and second long holes 15 and 16, thereby realizing the movement and sealing problems of the sleeve 1 relative to the positioning shaft 41 after the positioning shaft 41 extends out of the sleeve 1. At the same time, the action of the sleeve 1 on the inner sleeve 7 can support the positioning shaft 41 and avoid forming a cantilever structure.

[0047] Specifically, the aperture of the first mounting hole is set to be smaller than that of the second mounting hole, and the positioning shaft 41 is arranged as a stepped shaft to facilitate installation and positioning.

[0048] Preferably, a floating ring 11 for floating and sinking and a sinking ring 12 for counterweight are connected below the sleeve 1. The floating ring 11 moves along the axial direction of the insertion rod 2. The floating ring 11 generates buoyancy in water to push the sleeve 1 to rise and fall. After the floating ring 11 emerges from the water surface to a certain height, the buoyancy generated is less than the gravity of the assembly of the sleeve 1, the floating ring 11, and the sinking ring 12, and thus it sinks into the water surface, thereby ensuring the smooth sinking of the sleeve 1 and further making full use of the kinetic energy of ocean waves.

[0049] Specifically, the sinking ring 12 is sleeved on the insertion rod 2, and a sliding section is arranged below it. A dynamic seal is arranged between the sliding section and the insertion rod 2 for sealing, and it is ensured to move up and down along the insertion rod 2. The floating ring 11 and the bottom end of the sleeve 1 are connected by a connecting rod 13. The connecting rod 13 is sleeved on the insertion rod 2. The lower end of the connecting rod 13 is connected to the upper surface of the floating ring 11 by welding, and the upper end is detachably connected to the connecting section of the lower surface of the floating ring 11 through a sealing joint.

[0050] Specifically, the length of the connecting rod 13 is designed such that the sleeve 1 is at a certain distance above the water surface. The sleeve 1 moves up and down driven by the floating ring 11 and the sinking ring 12, avoiding the direct impact of sea waves on the sleeve 1 and damaging the sleeve 1 and its internal structure.

[0051] Preferably, a limiting platform 22 for restricting the position of the sinking ring 12 is provided on the insertion rod 2. After the sliding section of the sinking ring 12 abuts against the upper surface of the limiting platform 22, the lowest position of the sinking ring 12 is restricted, and thus the lowest position of the sleeve 1 is also restricted. The highest position of the sleeve 1 is limited by the installation of the insertion rod 2 and the sleeve 1, determining the floating height of the sleeve 1. Further, a stepped surface is provided below the connecting flange of the insertion rod 2 to abut against the bottom of the sleeve 1 as a limiting structure for the upper travel limit, and a structure similar to the limiting platform 22 can be specifically adopted.

[0052] Specifically, the floating ring 11 and the sinking ring 12 are integrally formed, and a cavity is formed inside, in which liquid can be filled and fixed for counterweight.

[0053] Preferably, the first ratchet mechanism 42 includes: an outer ring 421, a turntable 422, a pawl 423, a sliding box 424 and a first spring 425. The outer ring 421 is sleeved outside the turntable 422. The sliding box 424 is arranged on the turntable 422. One end of the pawl 423 is rotatably connected to the sliding box 424, and the other end is supported by the first spring 425 and engages in the tooth groove of the internal gear ring of the outer ring 421. Through the cooperation of the pawl 423 and the internal gear ring of the outer ring 421, when the outer ring 421 rotates counterclockwise, the pawl 423 engages in the tooth groove, and the pawl 423 drives the turntable 422 to rotate counterclockwise; when the outer ring 421 rotates clockwise, the pawl 423 slides over the teeth of the internal gear ring of the outer ring 421, and the outer ring 421 idles relative to the turntable 422. The structure of the second ratchet mechanism 43 is the same as that of the first ratchet mechanism 42. By the installation directions of the two and the positions where the two racks are installed, it is ensured that the two idle alternately without affecting each other. And their sizes are the same, ensuring that the driving force arm lengths of the two are the same.

[0054] Preferably, a main groove 61, a connecting channel 62 and a secondary groove 63 are formed in the turntable 422. The main groove 61 is connected to the secondary groove 63 through the connecting channel 62. The main groove 61, the connecting channel 62 and the secondary groove 63 are all filled with hydraulic oil;

[0055] The sliding box 424 is hermetically and slidably arranged in the main groove 61. A second spring 64 is provided between the sliding box 424 and the bottom of the main groove 61, and the second spring 64 has a tendency to prevent the sliding box 424 from moving towards the bottom of the main groove 61.

[0056] A centrifugal block 65 is arranged in the auxiliary groove 63. The centrifugal block 65 is hermetically and slidably arranged in the auxiliary groove 63. A cover plate 66 is provided at the notch of the auxiliary groove 63. A third spring 67 is provided between the centrifugal block 65 and the cover plate 66, and the third spring 67 has a tendency to prevent the centrifugal block 65 from moving towards the cover plate 66.

[0057] During the power generation process, when the waves are large and the rising and falling speeds of the sleeve 1 are relatively fast, the rotating speed of the turntable 422 is relatively fast. The centrifugal block 65 slides outwards under the action of centrifugal force, thereby compressing the third spring 67. After the centrifugal block 65 slides, hydraulic oil is pumped into the auxiliary groove 63, driving the sliding box 424 to compress the second spring 64 and then approach the bottom of the main groove 61. Furthermore, the pawl 423 disengages from the internal gear ring of the outer ring 421 of the wheel, so that the outer ring 421 of the wheel no longer drives the turntable 422 to rotate, preventing the turntable 422 and the flywheel 46 from rotating too fast and burning out the generator 3. When the rotating speed is within the normal range, the centrifugal force received by the centrifugal block 65 is not sufficient to overcome the elastic force of the third spring 67, and the centrifugal block 65 slides a small distance or does not slide, ensuring normal operation.

[0058] Specifically, the main groove 61 is provided with a pressing plate 426 for pressing the sliding box 424 to prevent the sliding box 424 from sliding out of the main groove 61.

[0059] Preferably, the sliding box 424 is of a hollow structure, and an oil passing hole 4241 is opened at the bottom of the sliding box 424. The oil passing hole 4241 communicates with the main groove 61 to enable the hydraulic oil to drive the sliding box 424 to move better.

[0060] Preferably, the sliding box 424 is made of polytetrafluoroethylene, and the centrifugal block 65 is made of stainless steel. The weight of the centrifugal block 65 is greater than the weight of the sliding box 424, so that at the same rotating speed, the centrifugal force received by the sliding box 424 is smaller than that of the centrifugal block 65.

[0061] Specifically, a solar panel can also be arranged on the upper surface of the sleeve 1 for power generation.

[0062] The working principle of the device of the present application:

[0063] The sea waves cause the sleeve 1 to rise. The first rack 44 rises with the sleeve 1. The first rack 44 drives the outer ring 421 of the first ratchet mechanism 42 to rotate counterclockwise, thereby driving the turntable 422 to rotate. The turntable 422 drives the positioning shaft 41 and the flywheel 46 to rotate. The positioning shaft 41 drives the generator 3 to generate electricity through the transmission component. The second rack 45 rises with the sleeve 1. The second rack 45 drives the outer ring 421 of the second ratchet mechanism 43 to rotate clockwise, and the outer ring 421 idles relative to the turntable 422.

[0064] The sea waves cause the sleeve 1 to descend. The first rack 44 descends with the sleeve 1. The first rack 44 drives the outer ring 421 of the first ratchet mechanism 42 to rotate clockwise, and the outer ring 421 idles relative to the turntable 422. The second rack 45 descends with the sleeve 1. The second rack 45 drives the outer ring 421 of the second ratchet mechanism 43 to rotate counterclockwise. The outer ring 421 drives the turntable 422 to rotate. The turntable 422 drives the positioning shaft 41 and the flywheel 46 to rotate. The positioning shaft 41 drives the generator 3 to generate electricity through the transmission component.

[0065] The flywheel 46 adjusts the situation where the rotational speed of the outer ring 421 is lower than that of the flywheel 46 caused by the low sea wave energy. The centrifugal block 65 adjusts the maximum rotational speed to avoid burning out the generator 3.

[0066] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some or all of the technical features; and these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
