Detailed implementation manners

[0032] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0033] The technical solution of the utility model involves the use of one-way bearings for one-way rotation installation. For example, the second sprocket 305 is installed on the translation disk 302 through a one-way bearing, while the parts without limiting the rotation direction are connected by deep groove ball bearings. For example, the first gear 306 is installed on the gear frame 308 through a deep groove ball bearing. The one-way bearings and deep groove ball bearings are both commercially available products, and the specific models are the adaptability selection of technicians in this field, which will not be repeated here.

[0034] Embodiment 1:

[0035] This embodiment provides a power conversion transmission device based on wave energy drive, specifically as follows Figures 1 - 13 As shown, it includes a mounting frame 1, a power input assembly 2, a power conversion assembly 3, and a power output assembly 4. The mounting frame 1 includes a mounting cylinder 103 that provides an installation space for the power input assembly 2, and a plurality of legs are installed on the mounting cylinder 103. The power input assembly 2 includes a rocker mounting seat 203 installed below the mounting cylinder 103, a rocker 202 suspended in the rocker mounting seat 203, and a swing ball 201 installed at the bottom of the rocker 202.

[0036] The power conversion assembly 3 includes a translation disk 302 movably mounted in the inner cavity of the mounting cylinder 103, a gear rack 308 fixedly mounted in the inner cavity of the mounting cylinder 103, and a conversion unit; the conversion unit includes a chain 303, a second sprocket 305 unidirectionally mounted on the translation disk 302, a first sprocket 304 unidirectionally mounted on the gear rack 308, and a third gear 310; the top of the rocker 202 extends into the inner cavity of the mounting cylinder 103 and is movably connected to the translation disk 302; N second sprockets 305 distributed in an annular manner, an annular gear rack 308, and a third gear 310. The distributed N first sprockets 304 are staggered one by one and connected through a ring-shaped chain 303. The second sprockets 305 are all located on the outside of the chain 303, and the first sprockets 304 are all located on the inside of the chain 303, as shown in the power conversion component 3; the first sprocket 304 is provided with a second gear 309, and the first sprocket 304 transmits power to the second gear 309 in one direction, and the second gear 309 is connected to the third gear 310; the third gear 310 is connected to the power output component 4; N is a positive integer.

[0037] The wave energy with chaotic directions is transmitted to the power conversion component 3 through the rocker 202 suspended in the power input component 2, and is converted into power with a single direction by the power conversion component 3, and then stably output through the power output component 4.

[0038] The technical solution of the utility model involves that the one-way rotation installation is realized by using one-way bearings, specifically one-way roller bearings, because of their high load-bearing capacity and durability; for example, the second sprocket 305 is installed on the translation plate 302 through a one-way roller bearing, and the second gear 309 and the first sprocket 304 are also connected through a one-way roller bearing. Deep groove ball bearings are used for connection at places where the rotation direction is not restricted, for example, the first gear 306 is installed on the gear frame 308 through a deep groove ball bearing. The one-way roller bearings and deep groove ball bearings are both commercially available products, and the specific models are adaptively selected by those skilled in the art, and will not be repeated here.

[0039] When the pendulum ball 201 is shaken by waves, the power is transmitted to the translation plate 302 through the rocker 202. At this time, the end of the rocker 202 away from the pendulum ball 201 will slide in the reserved groove on the translation plate 302 and move the translation plate 302 to start horizontal movement. The rocker 202 is no longer vertical. Since the first sprocket 304 and the second sprocket 305 both rotate in one direction, when the translation plate 302 moves horizontally, the second sprocket 305 pulls the chain 303, and the chain 303 starts to drive part of the first sprocket 304 and all the second sprockets 305 to rotate. Among them, one of the first sprockets 304 does not rotate, and the first sprocket 304 and the second sprocket 305 rotate in opposite directions. The first sprocket 304 utilizes the locking property of the one-way roller bearing to drive the corresponding second gear 309 to rotate in one direction, and the second gear 309 drives the third gear 310 to rotate. At this time, the third gear 310 drives the output shaft 401 to rotate in one direction to output power, and on the other hand, the third gear 310 transmits the power to the second gear 309 connected to the first sprocket 304 that does not rotate. At this time, because the one-way roller bearing will not be locked, the second gear 309 will not drive the corresponding first sprocket 304; when the swing ball 201 is reset, the rocker 202 will return to the vertical state. Similarly to the above, the power is still converted and transmitted to the third gear 310, and then output.

[0040] The device can be installed vertically on a floating object on the water surface, and the waves are used to push the pendulum ball 201 to swing left and right to achieve power transmission; at the same time, the device can also be installed obliquely or horizontally on the shore, and the waves are used to push the pendulum ball 201 floating on the water surface to swing up and down to achieve power transmission.

[0041] Through the above arrangement, the power conversion component 3 can convert the irregular swinging power input by the power input component 2 into a unidirectional rotating power output, and effectively utilize the wave energy to convert into power.

[0042] Embodiment 2:

[0043] This embodiment is further expanded on the basis of embodiment 1. Figure 6As shown, a plurality of first gears 306 are rotatably connected to the gear rack 308, and the first gears 306 are respectively engaged with the third gear 310 and the second gear 309.

[0044] When the first sprocket 304 drives the second gear 309 to rotate, the second gear 309 will first drive the first gear 306, and the first gear 306 will then drive the third gear 310 to rotate. Through this setting, the distance between the first sprocket 304 and the translation disk 302 can be extended. On the one hand, it can provide a larger space for the movement of the translation disk 302, so that when the pendulum ball 201 swings with an increased amplitude due to a larger wave acting force, the translation disk 302 can move smoothly and utilize all the energy supplied by the larger waves. On the other hand, the length of the chain 303 is extended, so that when the translation disk 302 moves, the overall fluctuation amplitude of the chain 303 is reduced, improving the working stability of the chain 303.

[0045] Embodiment 3:

[0046] This embodiment is further extended on the basis of Embodiment 1, specifically as Figures 1 - 2 shown, the support feet include a first support foot unit 101 and a second support foot unit 102. The second support foot unit 102 is installed on the installation cylinder 103, and the first support foot unit 101 and the second support foot unit 102 are slidably arranged, and multiple support feet are independent of each other.

[0047] According to the specific installation position, adjust the overlapping length of the first support foot unit 101 and the second support foot unit 102, that is, change the length of the support feet, so that the installation cylinder 103 is horizontally placed, that is, the rocker 202 is perpendicular to the translation disk 302 in the initial position, to ensure the stability of the operation of the entire device.

[0048] Embodiment 4:

[0049] This embodiment is further extended on the basis of Embodiment 1, specifically as Figure 3 shown, a limit ring 301 for restricting the movement amplitude of the translation disk 302 is installed on the installation cylinder 103, and a buffer pad is covered on the inner ring of the limit ring 301.

[0050] The setting of the limit ring 301 is to limit the translation disk 302 and effectively prevent the pendulum ball 201 from hitting the support feet during the swing due to overly strong waves.

[0051] Embodiment 5:

[0052] This embodiment is further extended on the basis of Embodiment 1, specifically as Figure 8 shown, a plurality of movable balls 307 are arranged on both sides of the translation disk 302 to reduce the movement resistance of the translation disk 302.

[0053] By arranging the rolling balls 307 on the translation disk 302, the sliding friction during the movement of the translation disk 302 can be changed into rolling friction, effectively reducing the movement resistance of the translation disk 302 and improving the energy conversion efficiency of the power conversion assembly 3.

[0054] Embodiment 6:

[0055] This embodiment is further extended based on Embodiment 1, specifically as Figure 7 shown. A connecting ball 204 is fixedly installed on the rocker 202. The rocker mounting base 203 of the mounting seat is connected to the rocker 202 through the connecting ball 204. The distance from the connecting ball 204 to the end of the rocker 202 away from the pendulum ball 201 is less than the distance from the connecting ball 204 to the pendulum ball 201.

[0056] Taking the connecting ball 204 as the fulcrum and using the lever principle, the force provided by the swing at the pendulum ball 201 is amplified and transmitted to the translation disk 302, improving the output power at the output shaft 401.

[0057] Embodiment 7:

[0058] This embodiment is further extended based on Embodiment 6, specifically as Figure 10 shown. A notch is provided on the translation disk 302. The end of the rocker 202 away from the pendulum ball 201 is a ball head, and the ball head is movably inserted into the notch.

[0059] By arranging the end of the rocker 202 as a ball head, the wear degree during the swing of the rocker 202 can be effectively reduced.

[0060] Embodiment 8:

[0061] This embodiment is further extended based on Embodiment 6, specifically as Figure 11 shown. A ball head bearing 311 is installed on the translation disk 302. The end of the rocker 202 away from the pendulum ball 201 is movably connected to the inner ring of the ball head bearing 311. The ball head bearing is a commercially available product, and the specific model is adaptively selected by those skilled in the art and will not be elaborated here.

[0062] By arranging the ball head bearing 311, when the rocker 202 swings, it will relatively slide with the inner ring of the ball head bearing 311, and the wear is mainly concentrated on the ball head bearing 311, and the rocker 202 is basically not worn. The wear degree during the swing of the rocker 202 can be effectively reduced, and the ball head bearing 311 can be replaced after working for a certain period.

[0063] Embodiment 9:

[0064] This embodiment is further extended based on Embodiment 1, specifically as Figure 5 、 Figure 13As shown, the power output assembly 4 includes an output shaft 401 drivingly connected to the third gear 310, and the third gear 310 transmits power to the output shaft 401 in one direction. The output shaft 401 is provided with a flywheel 402 for maintaining the continuous output of the output shaft 401.

[0065] The third gear 310 and the output shaft 401 are also connected through a one-way roller bearing to achieve the purpose of unidirectional transmission of power from the third gear 310 to the output shaft 401. Since the swing of the swing ball 201 is mostly reciprocating, the translation disk 302 will stop moving or move slowly when the swing ball 201 swings and changes direction. After the flywheel 402 is set, when the translation disk 302 moves, the output shaft 401 will drive the flywheel 402 to rotate. After the translation disk 302 stops temporarily or moves slowly, the flywheel 402 will continue to rotate smoothly due to the inertia. At this time, the output shaft 401 rotates faster than the third gear 310, so the one-way roller bearing will not be locked at this time, so the power on the output shaft 401 will not be transmitted to the third gear 310. When the swing amplitude of the swing ball 201 suddenly increases due to waves, the third gear 310 uses the locking property of the one-way roller bearing to drive the power of the output shaft 401 to increase immediately. Since the flywheel 402 also needs to be driven to speed up at this time, part of the power needs to be transferred to the flywheel 402, so the speed change of the output shaft 401 will be relatively stable. Through the above arrangement, the output shaft 401 can continuously and stably output power when the swing ball 201 swings and changes direction and the swing amplitude suddenly changes.

[0066] Embodiment 10:

[0067] This embodiment provides a power generation device driven by wave energy, including a power conversion component and a power generation component. The power conversion component converts wave energy into stable power and transmits it to the power generation component. The power generation component uses the power to generate electricity. The power conversion component adopts a power conversion transmission device driven by wave energy as described in any one of Examples 1 to 9.

[0068] When the power generation device is installed on a ship, when the ship is on the water, the waves will cause the ship to bump, so the power generation device installed on the ship will also be affected, and the swing ball 201 will start to swing irregularly. At this time, the power is transmitted to the translation plate 302 through the rocker 202, and the translation plate 302 starts to move in the opposite direction of the swing ball 201. The power begins to be converted and finally transmitted to the output shaft 401 through the third gear 310. Then the output shaft 401 outputs the power to the power generation component, and the device starts to generate electricity. In this way, the clean energy is utilized to reduce the dependence on traditional energy and reduce the impact on the environment.

[0069] The above are only the preferred embodiments of the present utility model, and do not impose any form of limitation on the present utility model. Any simple modification or equivalent change made to the above embodiments based on the technical essence of the present utility model shall fall within the protection scope of the present utility model.
