[0002] As the world's demand for clean energy becomes increasingly urgent, the limited reserves of traditional fossil energy and environmental problems have prompted countries around the world to actively explore new paths for renewable energy. The ocean, as the largest energy treasure house on the earth, contains huge energy potential. Among them, wave energy has become one of the new energy sources with great development value due to its rich reserves, wide distribution, high energy density and renewable characteristics. The theoretical reserves of global ocean wave energy resources are as high as billions of kilowatts, and the wave movement is continuous and regular, which provides the possibility for stable power generation. Under the general trend of energy transformation, wave energy power generation technology is not only a key breakthrough in solving the problem of energy shortage, but also an important direction for promoting green and sustainable development.

[0003] At the same time, traditional cage aquaculture faces problems such as high energy costs and heavy dependence on fossil energy. In the context of increasingly stringent environmental protection policies, a green and sustainable development model is urgently needed. Cage aquaculture devices based on wave energy power generation have emerged. They can use wave energy to provide stable electricity for aquaculture equipment and reduce operating costs. At the same time, they are in line with the global green development trend, providing innovative ideas and feasible solutions for solving the energy problems of cage aquaculture and promoting the transformation of fisheries to low-carbon and environmentally friendly ones.

[0004] However, in actual applications of current wave energy power generation devices and the cage aquaculture devices that rely on them, although the wave energy power generation devices are not easily affected by the attachment of shellfish and crustaceans because they are located on the sea surface and are frequently impacted by seawater, the cages are facilities placed in specific marine aquaculture areas, and their net surfaces are extremely prone to breeding a large number of such marine organisms.

The rope body of the wave traction rope 28 passes through the center line hole of the threading tube 26 to the proximal side under the guidance of the two wire pulleys 141, and is then bound to at least one mesh scraper box 27 at the lower rope end. The mesh scraper The box 27 is divided into three parts: an upper tongue box, a middle box and a lower tongue box. The upper tongue box and the lower tongue box are provided with arc-shaped tongue buckets in contact with or close to the mesh surface of the cage body 11, and the tongue buckets are inclined to receive the surface of marine organisms such as shellfish and crustaceans for convenient collection and feeding. In addition, a wire tube 271 is integrally provided at the center of the arc-shaped tongue bucket for the pulling rope 17 to pass through. The internal rotating roller of the middle box is press-fitted with a group of crushing rollers 272, and the shaft end of one of the crushing rollers 272 extends into the gear box on one side of the middle box and is connected to the driving ratchet gear 273 in the gear box.

[0020] When the waves act on the floating plate 21, it swings with the waves and drives the rotating shaft 211 to rotate. The first toothed pulley 212 on the rotating shaft 211 drives the toothed belt ratchet gear 241 on the wheel rod 24 to rotate in one direction through the toothed belt. When the wheel rod 24 rotates, the second toothed pulley 242 at one end drives the toothed pulley of the power generation component 25 to rotate through the toothed belt, so that the power generation component 25 generates electricity, which is supplied to the cage aquaculture device after voltage stabilization → frequency stabilization → filtering → rectification / inversion → power distribution protection; at the same time, the constraint wheel shaft 243 at the other end of the wheel rod 24 rotates with it, and the first line wheel 244 continues to idle because it has not moved to the flat key connection area. In addition, when the floating plate 21 swings, the wave traction rope 242 at the rear side is 8 reciprocates under the guidance of the wire wheel 141, driving the mesh scraper box 27 to slide up and down along the mesh surface of the cage body 11.

[0021] To sum up, through the cooperation between the wave power generation structure 2 and the cage structure 1, when the floating plate 21 swings with the waves, it drives the rotating shaft 211 to rotate, and the first toothed pulley 212 on the rotating shaft 211 drives the toothed belt ratchet gear 241 on the wheel rod 24 to rotate unidirectionally through the toothed belt.

[0022] As an embodiment of the present invention, Figures 1 to 4As shown, the interior of the floating board 21 is open to the direction opposite to the wave, and a connecting piece is connected to a rotating shaft 211 that rotates with the floating board 21 at the center of the open space, and the rotating shaft 211 is rotatably fitted in the bearings of the double arm ends of the supporting arms 22 extending into the open space of the floating board 21. The rotating shaft 211 is located on the shaft between the arm ends of the supporting arms 22 and is connected to two first toothed pulleys 212 by interference fit in a symmetrical manner, and the first toothed pulleys 212 are all matched with the toothed belt and the toothed belt ratchet gear 241 connected to the wheel rod 24 with a key for transmission, and the rotation force direction of the toothed belt ratchet gear 241 is opposite, the wheel rod 24 is located between the toothed belt ratchet gears 241 and is interference fit in the lower bearing of the bearing frame 23, and the two ends of the wheel rod 24 are respectively connected with the second toothed belt pulley 242 and the threaded connection by bolts. There is a constrained wheel shaft 243, wherein the second toothed pulley 242 cooperates with the toothed belt and the toothed pulley transmission at the shaft end of the power generation component 25, and the power generation component 25 is connected to the upper surface of the pipe sleeve 14 in the same position by bolts. The rod body of the constrained wheel shaft 243 is divided into a rod body with a flat key and a smooth rod body, and initially, a first wire wheel 244 is rotatably set on the smooth rod body, and the first wire wheel 244 is connected to the flat key part of the constrained wheel shaft 243 in a key connection manner after sliding along the axial direction. The lower end of the bearing frame 23 is connected to the centrifugal side of the upper surface of the pipe sleeve 14 opposite to the branch pipe 15 with bolts, and the upper end of the bearing frame 23 is fixed to the upper cross bar of the support arm 22, and the wire groove of the first wire wheel 244 is bound to the upper end of the nearby pulling rope 17, and the number of bound pulling ropes 17 is the same as the number of floating boards 21.

[0023] After entering the aquaculture and harvesting season, the first line wheel 244 can be slid axially to the flat key area. When the waves hit the floating plate 21, it rotates synchronously with the constraint wheel shaft 243 through the key connection, and then reels and pulls the pulling rope 17, and thereby pulls the lower side net tube 111 of the cage body 11, and gradually drags the cage body 11 out of the sea, so that the catch in the cage body 11 can be collected.

[0024] To sum up, through the cooperation of the constraint wheel shaft 243, the first line wheel 244 and the pulling rope 17, during the aquaculture and harvesting season, the first line wheel 244 is slid to connect with the flat key part of the constraint wheel shaft 243, and the wave energy is used to drive the constraint wheel shaft 243 to rotate, and then the first line wheel 244 is used to reel in the pulling rope 17 to gradually drag the net cage body 11 out of the sea, which simplifies the net collection process, reduces the intensity of manual labor, and improves the efficiency of collecting fish.

[0025] Working principle: When working, first assemble the cage structure 1, fix the upper and lower mesh pipes 111 on the cage body 11, combine the ring pipe into the floating pipe 12 through the pipe set 14, connect the branch pipe 15 and the binding ring pipe 16, bind the upper side mesh pipe 111, arrange the pulling rope 17 and the pedal 13, position the floating pipe 12, and install the wire pulley 141 on the lower surface of the corresponding pipe set 14. Then install the wave power generation structure 2, assemble the floating plate 21 with counterweight and the rotating shaft 211, install the wheel rod 24, toothed belt ratchet gear 241 and other transmission parts 1. Connect the first toothed pulley 212 and the toothed ratchet gear 241, install the second toothed pulley 242, the power generation component 25, the constraint wheel shaft 243 and the first wire wheel 244, and finally install the threading tube 26 and the internal wheel tube 261, the covering gear 262, the driven gear 263, the spring rod 264, etc., bind the wave traction rope 28 and the pull rope 266, connect the second wire wheel 265, the tooth plate 267, and the mesh scraper box 27, connect the first wire wheel 244 to the pulling rope 17, and finally debug to ensure that all components are operating normally; During normal operation, when waves act on the floating plate 21, the floating plate 21 swings with the waves, driving the internal rotating shaft 211 to rotate. The first toothed pulley 212 on the rotating shaft 211 drives the toothed ratchet gear 241 on the wheel rod 24 to rotate unidirectionally via the toothed belt. The unidirectional transmission characteristic of the ratchet gear ensures that power is transmitted in a single direction. When the wheel rod 24 rotates, the second toothed pulley 242 at one end drives the toothed pulley of the power generation component 25 to rotate via the toothed belt, causing the power generation component 25 to work and generate electricity. After undergoing the steps of voltage stabilization, frequency stabilization, filtering, rectification / inversion, and power distribution protection, the electricity is supplied to the cage aquaculture device for use in oxygenation, water quality monitoring, feeding, lighting, equipment power, and environmental control. At the same time, the constraint wheel shaft 243 at the other end of the wheel rod 24 rotates with it. However, the first spool 244 provided thereon does not move to the area of ​​the flat key connection. Therefore, the first spool 244 continues to idle during this process. In addition, when the floating board 21 swings, the wave pulling rope 28 at the rear side thereof makes a reciprocating motion under the guidance of the wire pulley 141, driving the mesh scraper box 27 connected at the lower end to slide up and down along the mesh surface of the mesh box body 11. The upper and lower tongue boxes of the mesh scraper box 27 adopt an arc surface design, which fits tightly with the mesh surface, and can effectively scrape off attached shellfish, crustaceans and other marine organisms. The scraped organisms automatically slide into the middle box due to the tilt angle of the tongue bucket. At the same time, when the wave pulling rope 28 moves, the covering gear 262 in the threading tube 26 is elastically supported by the spring rod 264. Under pressure, it is always in frictional contact with the surface of the rope body and rotates with the movement of the rope body. The covering gear 262 drives the driven gear 263 to rotate through meshing, which in turn drives the second line wheel 265 to retract and release the pull rope 266. The pull rope 266 pulls the tooth plate 267 to slide up and down in the gear box, meshing with the driving ratchet gear 273, driving the crushing roller 272 in the middle box to rotate unidirectionally. The ratchet gear ensures that the crushing direction remains unchanged. The crushed biological debris falls into the water body of the cage through the inclined surface of the lower tongue box, becoming natural bait for farmed fish, thus realizing resource recycling. After entering the aquaculture harvesting season, the aquaculture personnel can use the electricity generated by the wave energy power generation device to cooperate with the winding equipment to pull the lifting rope 17, or manually pull the upper end of the lifting rope 17. Furthermore, the first line wheel 244 can be slid axially to the flat key area. When the wave hits the floating plate 21, it rotates synchronously with the constraint wheel shaft 243 through the key connection, and then reels and pulls the lifting rope 17, and thereby pulls the lower side net tube 111 of the cage body 11, and gradually drags the cage body 11 out of the sea, so that the catch in the cage body 11 can be collected.

[0026] It should be noted that the toothed ratchet gear 241 is similar to the ratchet gear, but the circumferential surface of the toothed ratchet gear 241 is a toothed pulley, which can be understood as a combination of a toothed pulley sleeve and a ratchet gear structure; if the tooth plate 267 has insufficient weight, it is necessary to add a counterweight to the lower end of the tooth plate 267 to ensure that the above-mentioned working principle can be realized.

[0027] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
