[0002] Through the combination of photovoltaics and fish cages, aquaculture cages are set in the waters below the photovoltaic panels, and the shading effect provided by the photovoltaic panels is used to create a suitable growth environment for fish cage farming, realize the three-dimensional utilization of water resources, and improve the efficiency of resource utilization; the water in the fish box is exchanged with the water in the water area in real time, so that the fish excrement in the fish box is discharged smoothly, and at the same time, small fish and shrimps in the water area can pass through the mesh to the fish box to be fed by the fish, and it also plays a role in sharing oxygen; but the fish box structure has the following disadvantages: because the annular breeding space has a restraining effect on the fish, the foraging range of the farmed fish is concentrated, so there is a problem of food shortage in the natural state; therefore, additional feed is needed; in the process of additional feed supplementation, there is a problem of uneven feeding, and the feed put into the annular breeding space is easy to escape to the outside of the annular breeding space through the mesh on the fish box under the activity and disturbance of the fish, thereby causing a waste of feed. Summary of the invention

[0003] Purpose of the invention: In order to overcome the deficiencies in the prior art, the present invention provides a flexible floating photovoltaic system for fish-light complementation, which can avoid waste in the feeding process.

[0004] Technical solution: To achieve the above-mentioned purpose, a flexible floating photovoltaic system for fish-photovoltaic complementarity of the present invention comprises an annular disc-shaped photovoltaic power generation platform, below which a number of fish box floats are distributed in a circular array along the axis; the center of each fish box float is a disc-shaped float portion, and the outer circle of each disc-shaped float portion is synchronously provided with a circle of annular fish cage portions coaxially, and the inside of the annular fish cage portion is a circle of annular breeding space.

[0005] Furthermore, the annular fish cage portion includes an outer annular mesh wall and an inner annular wall. The inner annular wall is coaxially and detachably fixedly sleeved on the outer ring of the disc-shaped float portion. An annular breeding space is formed between the outer annular mesh wall and the inner annular wall. An annular bottom wall is arranged at the lower part of the annular breeding space. The inner and outer circles of the annular bottom wall are respectively integrally connected to the lower end contours of the inner annular wall and the outer annular mesh wall. A plurality of mesh holes are evenly hollowed out on the outer annular mesh wall.

[0006] Furthermore, a feed guide cone ring wall is arranged above the annular breeding space, and the outer ring contour of the upper end of the feed guide cone ring wall is integrally connected to the upper end contour of the outer ring mesh wall; an annular feeding opening is formed between the inner ring contour of the lower end of the feed guide cone ring wall and the inner ring wall.

[0007] Furthermore, the upper end of the disc-shaped float portion is coaxially fixedly connected with a rotating shaft, the upper end of the rotating shaft is rotatably mounted on the end of a float support arm through a bearing, and the lower part of each annular disc-shaped photovoltaic power generation platform is fixedly supported and mounted on a plurality of float support arms.

[0008] Furthermore, a structural feed funnel is fixedly connected to the end of the float support arm; the lower end of the structural feed funnel is a flat leakage pipe, and the two long side contours of the lower end of the flat leakage pipe are respectively integrally provided with a first strip piece a and a second strip piece b along the length direction; the lower end contours of the first strip piece a and the second strip piece b are slidably or gap-matched with the upper surface of the feed guide cone ring wall, and a feed accumulation groove that passes through the length direction is formed between the first strip piece a and the second strip piece b, and the lower end of the flat leakage pipe is connected to the feed accumulation groove; a plurality of scraping tips are fixedly provided on the upper surface of the feed guide cone ring wall in a circular arrangement along the axis; when the structural feed funnel is relatively fixed, during the process of the fishing box float rotating one circle around its own axis, the plurality of scraping tips pass through the feed accumulation groove one by one.

[0009] Furthermore, a central motor is coaxially installed below the axis of the annular disc-shaped photovoltaic power generation platform, and the central motor is fixedly supported and connected to several structural feed funnels around it through structural brackets; the output shaft at the lower end of the central motor is coaxially driven and connected to a reel wound with multiple layers of cloth tape a, and the reel leads out several taut underwater belts along the tangential direction, and the ends of each underwater belt are fixedly connected to the outer peripheral surface of an outer ring mesh wall; the axis of the upper end of the disc-shaped float part is connected to the float bracket arm through a torsion spring, and in the initial state, the torsion spring applies a rotational torque to the disc-shaped float part, so that the fishing box float tends to rotate along the axis, and the taut underwater belt inhibits the fishing box float from rotating along the axis, and when the reel gradually leads out the underwater belt, the fishing box float rotates along the axis driven by the torsion spring, so that the underwater belt is gradually wound around the outer peripheral surface of the outer ring mesh wall, thereby closing the mesh on the outer ring mesh wall.

[0010] Furthermore, a feed feeder is fixedly installed above the central motor through a structural bracket; a feeding nozzle at the lower end of the feed feeder corresponds to a feeding port of the structural feed hopper.

[0011] Furthermore, a working method of a flexible floating photovoltaic system for complementary fishing and photovoltaic is provided: when manual feeding is required, the feeding nozzle at the lower end of the feed feeder feeds a predetermined amount of feed into the structural feed funnel, and the central motor is controlled to cause the reel to gradually lead out the underwater belt wound by itself, and the float of the fishing box rotates one circle along the axis under the drive of the torsion spring; this continues for a certain period of time, and after the feed scattered in the annular breeding space is eaten up, the central motor is controlled to cause the reel to forcibly reel in and recycle the led-out underwater belt, so that the float of the fishing box overcomes the torsion spring and rotates in the opposite direction to the initial state under the traction of the underwater belt.

[0012] Beneficial effect: During the artificial feeding process of the present invention, when the float of the fishing box rotates around its own axis for one circle, a number of scraping tips pass through the feed accumulation groove one by one, and continuously scrape out the fish feed in the feed accumulation groove. The scraped feed leaks into the annular breeding space through the annular feeding port under the action of gravity, so that the feed is evenly scattered in the annular breeding space along a circular path, so that the fish in the annular breeding space can eat more evenly; at the same time, because the mesh holes on the outer ring mesh wall are surrounded and blocked by the underwater belts wrapped around them, the feed scattered in the annular breeding space will not escape to the outside of the annular breeding space through the mesh holes on the outer ring mesh wall under the activity and disturbance of the fish, thereby avoiding the problem of feed waste.

[0019] The present invention will be further described below in conjunction with the accompanying drawings.

[0020] As attached Figures 1 to 6 A flexible floating photovoltaic system for fishery-solar complementary use is shown in FIG. Figure 1 and 2 As shown, it includes an annular disc-shaped photovoltaic power generation platform 30. In order to prevent the annular disc-shaped photovoltaic power generation platform 30 from floating away, mooring lines are connected around the annular disc-shaped photovoltaic power generation platform 30. A number of fish box floats 15 are distributed in a circular array along the axis below the annular disc-shaped photovoltaic power generation platform 30. The annular disc-shaped photovoltaic power generation platform 30 is supported by the number of fish box floats 15, and the number of fish box floats 15 float in the water; the center of each fish box float 15 is a disc-shaped float part 9, and the outer circle of each disc-shaped float part 9 is synchronously provided with a circle of annular fish cage parts 7 coaxially, and the inside of the annular fish cage part 7 is a circle of annular breeding space 20.

[0021] like Figure 4 and 5As shown, the annular fish cage portion 7 includes an outer ring mesh wall 7 and an inner ring wall 8. The inner ring wall 8 is coaxially detachably fixedly sleeved on the outer ring of the disc-shaped float portion 9. An annular breeding space 20 is formed between the outer ring mesh wall 7 and the inner ring wall 8. An annular bottom wall 21 is arranged at the lower part of the annular breeding space 20. The inner and outer circles of the annular bottom wall 21 are respectively connected integrally to the lower end contours of the inner ring wall 8 and the outer ring mesh wall 7. A plurality of mesh holes 6 are evenly hollowed out on the outer ring mesh wall 7. The size of the mesh holes 6 is determined according to the body shape of the fish to be cultured. An openable box door structure is provided on the annular bottom wall 21 for opening during harvesting.

[0022] A feed guide cone ring wall 2 is arranged above the annular breeding space 20, and the outer ring contour of the upper end of the feed guide cone ring wall 2 is integrally connected to the upper end contour of the outer ring mesh wall 7; an annular drop opening 5 is formed between the inner ring contour of the lower end of the feed guide cone ring wall 2 and the inner ring wall 8. The feed on the upper surface of the feed guide cone ring wall 2 will automatically slide obliquely downward under the action of gravity, and leak down to the annular breeding space 20 through the annular drop opening 5.

[0023] like Figure 3 and 4 The upper end of the disc-shaped float part 9 is coaxially fixedly connected with a rotating shaft 1, and the upper end of the rotating shaft 1 is rotatably mounted on the end of a float support arm 18 through a bearing, and the lower part of each annular disc-shaped photovoltaic power generation platform 30 is fixedly supported and mounted on a plurality of float support arms 18; the end of the float support arm 18 is fixedly connected with a structural feed funnel 17; the lower end of the structural feed funnel 17 is a flat leakage pipe 12, and the two long side contours of the lower end of the flat leakage pipe 12 are respectively integrally provided with a first strip piece 22a and a second strip piece 22b along the length direction; the first strip piece The lower end contours of 22a and the second strip piece 22b are slidably or gap-matched with the upper surface of the feed guide cone ring wall 2, and a feed accumulation groove 23 is formed between the first strip piece 22a and the second strip piece 22b along the length direction, and the lower end of the flat leakage pipe 12 is connected to the feed accumulation groove 23; when manual feeding is required, the feeding nozzle 16 at the lower end of the feed feeder 15 feeds a predetermined amount of feed into the structural feed funnel 17, and the feed entering the structural feed funnel 17 leaks down through the flat leakage pipe 12 to the feed accumulation groove 23 for accumulation.

[0024] A plurality of scraping tips 4 are fixedly arranged in a circle along the axis on the upper surface of the feed guide cone annular wall 2; when the structural feed funnel 17 is relatively fixed, during the process of the fish box float 15 rotating around its own axis, the plurality of scraping tips 4 pass through the feed accumulation groove 23 one by one, and continuously scrape out the fish feed in the feed accumulation groove 23, and the scraped feed leaks into the annular breeding space 20 through the annular feeding port 5 under the action of gravity, so that the feed is evenly scattered in the annular breeding space 20 along the circular path, so that the fish in the annular breeding space 20 can eat more evenly.

[0025] A central motor 13 is coaxially installed below the axis of the annular photovoltaic power generation platform 30. The central motor 13 is fixedly supported and connected to a plurality of structural feed hoppers 17 around it through a structural bracket 14. The output shaft at the lower end of the central motor 13 is coaxially driven and connected to a reel 11 wound with multiple layers of cloth tape 10a. Figure 6 As shown, the reel 11 leads out a plurality of taut underwater straps 10 along the tangential direction. The underwater straps 10 may be made of nylon fiber, and the ends of each underwater strap 10 are fixedly connected to the outer peripheral surface of an outer ring mesh wall 7; the axis of the upper end of the disc-shaped float portion 9 is connected to the float support arm 18 through a torsion spring 3. In the initial state, the torsion spring 3 applies a rotational torque to the disc-shaped float portion 9, so that the fishing box float 15 tends to rotate along the axis, and the taut underwater strap 10 inhibits the fishing box float 15 from rotating along the axis. When the reel 11 gradually leads out the underwater strap 10, the fishing box float 15 rotates along the axis driven by the torsion spring 3, so that the underwater strap 10 is gradually wound around the outer peripheral surface of the outer ring mesh wall 7, thereby closing the mesh 6 on the outer ring mesh wall 7.

[0026] A feed feeder 15 is fixedly mounted above the central motor 13 via a structural bracket 14 ; a feeding nozzle 16 at the lower end of the feed feeder 15 corresponds to a receiving port of a structural feed hopper 17 .

[0027] Working principle: Under normal breeding conditions, a number of fish box floats 15 float in the water, and the parts of the fish box floats 15 below the feed guide cone ring wall 2 are immersed in the water, so that the annular breeding space 20 is always filled with water and fish, and at the same time, a number of fish box floats 15 support the annular photovoltaic power generation platform 30 upward; because the device is in a floating state, no matter how the water level changes, the draft depth of each fish box float 15 is always stable; therefore, the fish in the annular breeding space 20 can always move in the water, and at the same time, the water in the annular breeding space 20 and the water in the water area are exchanged in real time through the meshes 6 on the outer ring mesh wall 7, so that the fish excrement in the annular breeding space 20 can be discharged smoothly, and at the same time, the water in the water area Small fish and shrimp can pass through the mesh 6 to reach the annular breeding space 20 to feed the fish, and also play a role in sharing oxygen; the mesh 6 on the outer ring mesh wall 7 can also prevent the fish raised in the annular breeding space 20 from being preyed upon by large carnivorous fish in the waters; because the annular breeding space 20 has a restraining effect on the fish, the foraging range of the farmed fish is concentrated, so there is a problem of food shortage in the natural state; therefore, additional feed is required; during the additional feed supplementation process, the feed put into the annular breeding space 20 can easily escape to the outside of the annular breeding space 20 through the mesh 6 on the outer ring mesh wall 7 under the activity and disturbance of the fish, thereby causing a waste of feed; in order to solve this problem, the solution of this process in this scheme is as follows:

[0028] When manual feeding is required, the feeding nozzle 16 at the lower end of the feed feeder 15 feeds a predetermined amount of feed into the structural feed hopper 17, and the feed entering the structural feed hopper 17 leaks down through the flat leakage pipe 12 to the feed accumulation trough 23 for accumulation. When the fish box float 15 does not rotate, the feed accumulated in the feed accumulation trough 23 cannot overflow smoothly, and the feed cannot slide smoothly into the annular breeding space 20;

[0029] At this time, the central motor 13 is controlled to make the reel 11 gradually lead out the underwater belt 10 wound around itself, and the fish box float 15 rotates one circle along the axis under the drive of the torsion spring 3, so that the underwater belt 10 is gradually wound around the outer peripheral surface of the outer ring mesh wall 7, thereby closing the mesh 6 on the outer ring mesh wall 7; at the same time, during the process of the fish box float 15 rotating one circle around its own axis, a number of scraping tips 4 pass through the feed accumulation groove 23 one by one, continuously scraping out the fish feed in the feed accumulation groove 23, and the scraped feed is pulled out by gravity. At the same time, since the mesh holes 6 on the outer ring mesh wall 7 are surrounded and blocked by the underwater belt 10 wrapped around them, the feed scattered in the annular breeding space 20 will not escape to the outside of the annular breeding space 20 through the mesh holes 6 on the outer ring mesh wall 7 due to the activities and disturbances of the fish, thereby avoiding the problem of feed waste.

[0030] After a certain period of time, when the feed scattered in the annular breeding space 20 is eaten up, the central motor 13 is controlled to make the reel 11 forcibly reel up and recover the drawn underwater belt 10, so that the fish box float 15 overcomes the torsion spring 3 and rotates in the opposite direction to the initial state under the traction of the underwater belt 10. At this time, the water in the annular breeding space 20 and the water in the water area are reconnected with each other through the mesh holes 6 on the outer ring mesh wall 7, and the normal breeding state is restored.

[0031] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
