Abstract
Description
Technical Field
[0001] This invention belongs to the field of solar-fishery complementary photovoltaics. Background Technology
[0002] By combining photovoltaics and fish cages, aquaculture cages are set up in the water area below the photovoltaic panels. The shading effect provided by the photovoltaic panels creates a suitable growth environment for fish cage aquaculture, realizing three-dimensional utilization of water resources and improving resource utilization efficiency. The water in the fish cages exchanges with the surrounding water in real time, allowing fish excrement to be discharged smoothly. At the same time, small fish and shrimp from the surrounding water can pass through the mesh into the fish cages to feed the farmed fish, and oxygen is also shared. However, the fish cage structure has the following drawbacks: the annular aquaculture space restricts the fish, concentrating their foraging range, which can lead to food shortages under natural conditions. Therefore, additional feed is required. During the process of supplementing feed, there is the problem of uneven feeding. Feed put into the annular aquaculture space can easily escape outside the annular aquaculture space due to the movement and disturbance of the fish, resulting in feed waste. Summary of the Invention
[0003] Purpose of the invention: In order to overcome the shortcomings of the existing technology, the present invention provides a flexible floating photovoltaic system that complements fishing and solar power, which can avoid the waste in the feeding process.
[0004] Technical solution: To achieve the above objectives, the present invention provides a flexible floating photovoltaic system for fishery-solar integration, comprising a disc-shaped photovoltaic power generation platform, with several fish box floats arranged in a circular array along the axis below the disc-shaped photovoltaic power generation platform; the center of each fish box float is a disc-shaped float section, and an annular fish cage section is synchronously and coaxially arranged on the outer ring of each disc-shaped float section, with an annular aquaculture space inside the annular fish cage section.
[0005] Furthermore, the annular fish trap includes an outer ring mesh wall and an inner ring wall. The inner ring wall is coaxially and detachably fixed to the outer ring of the disc-shaped float. An annular breeding space is formed between the outer ring mesh wall and the inner ring wall. An annular bottom wall is provided at the bottom of the annular breeding space. The inner and outer rings of the annular bottom wall are integrally connected to the lower contours of the inner ring wall and the outer ring mesh wall, respectively. Several mesh holes are evenly hollowed out on the outer ring mesh wall.
[0006] Furthermore, a feed guide cone ring wall is provided above the annular aquaculture space, and the outer contour of the upper end of the feed guide cone ring wall is integrally connected to the upper contour of the outer ring mesh wall; the inner contour of the lower end of the feed guide cone ring wall forms an annular feed outlet between the inner ring wall and the inner ring wall.
[0007] Furthermore, a rotating shaft is coaxially fixedly connected to the upper end of the disc-shaped float section. The upper end of the rotating shaft is rotatably mounted at the end of a float support arm via a bearing. The lower part of each ring-shaped photovoltaic power generation platform is fixedly supported on several 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 feed tube, and a first strip a and a second strip b are integrally set along the length direction on the two long sides of the lower end of the flat feed tube; the lower contours of the first strip a and the second strip b slide or gap with the upper surface of the feed guide cone ring wall, and a feed accumulation trough is formed between the first strip a and the second strip b along the length direction, and the lower end of the flat feed tube is connected to the feed accumulation trough; several scraping tips are fixedly arranged in a circle along the axis on the upper surface of the feed guide cone ring wall; when the structural feed funnel is relatively fixed, during the process of the fish box float rotating around its own axis, several scraping tips pass through the feed accumulation trough one by one.
[0009] Furthermore, a central motor is coaxially installed below the axis of the disc-shaped photovoltaic power generation platform. The central motor is fixedly supported and connected to several structural feed hoppers around it through a structural bracket. The output shaft at the lower end of the central motor is coaxially connected to a drum wound with multiple layers of cloth tape a. Several taut underwater straps are led out from the drum along the tangential direction. The end of each underwater strap is fixedly connected to the outer circumferential surface of an outer ring mesh wall. The upper axis of the disc-shaped float is connected to the float support arm through a torsion spring. In the initial state, the torsion spring applies rotational torque to the disc-shaped float, causing the fish box float to tend to rotate along the axis. The taut underwater straps inhibit the fish box float from rotating along the axis. When the drum gradually leads out the underwater straps, the fish box float rotates along the axis under the drive of the torsion spring, so that the underwater straps gradually wind around the outer circumferential surface of the outer ring mesh wall, thereby closing the mesh holes on the outer ring mesh wall.
[0010] Furthermore, a feed feeder is fixedly installed above the central motor via a structural support; the feed nozzle at the lower end of the feed feeder corresponds to the receiving port of the structural feed funnel.
[0011] Furthermore, a working method for a flexible floating photovoltaic system that integrates fish farming and solar power is as follows: When manual feeding is required, the feeding nozzle at the lower end of the feeder feeds a predetermined amount of feed into the structural feed funnel. The central motor is controlled to gradually draw out the underwater belt wound around itself by the drum. The fish box float rotates once along the axis under the drive of the torsion spring. After a certain period of time, when the feed scattered in the annular aquaculture space is consumed, the central motor is controlled to force the drum to wind up and retract the drawn underwater belt, thereby causing the fish box float to overcome the torsion spring and rotate back to the initial state under the pull of the underwater belt.
[0012] Beneficial effects: During the manual feeding process of this invention, as the float of the fish box rotates around its own axis, several scraping tips pass through the feed accumulation trough one by one, continuously scraping out the fish feed from the trough. The scraped feed, under the action of gravity, leaks down through the annular feed outlet into the annular aquaculture space, thereby evenly scattering the feed along the circular path within the annular aquaculture space, allowing the fish in the annular aquaculture space to eat more evenly. At the same time, because the mesh on the outer ring mesh wall is surrounded and sealed by the underwater straps wrapped around it, the feed scattered in the annular aquaculture space will not escape out of the annular aquaculture space due to the activity and disturbance of the fish, thus avoiding the problem of feed waste.

[0019] The invention will now be further described with reference to the accompanying drawings.
[0020] As attached Figures 1 to 6 The example shown is a flexible floating photovoltaic system that integrates fishing and solar power. Figure 1 and 2 As shown, the system includes a disc-shaped photovoltaic power generation platform 30. To prevent the disc-shaped photovoltaic power generation platform 30 from drifting away, mooring lines are connected around the disc-shaped photovoltaic power generation platform 30. Several fish box floats 15 are arranged in a circular array along the axis below the disc-shaped photovoltaic power generation platform 30. The disc-shaped photovoltaic power generation platform 30 is supported by several fish box floats 15, which float in the water. The center of each fish box float 15 is a disc-shaped float part 9. Each disc-shaped float part 9 is surrounded by a ring-shaped fish cage part 7, which is coaxially and synchronously arranged on the outer ring. Inside the ring-shaped fish cage part 7 is a ring-shaped aquaculture space 20.
[0021] like Figure 4 and 5As shown, the annular fish cage 7 includes an outer ring mesh wall 7 and an inner ring wall 8. The inner ring wall 8 is coaxially and detachably fixed to the outer ring of the disc-shaped float part 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 provided at the bottom of the annular breeding space 20. The inner and outer rings of the annular bottom wall 21 are integrally connected to the lower contours of the inner ring wall 8 and the outer ring mesh wall 7, respectively. The outer ring mesh wall 7 has a number of mesh holes 6 evenly hollowed out. The size of the mesh holes 6 is determined according to the size of the fish being raised. The annular bottom wall 21 has an openable door structure for opening during harvesting.
[0022] Above the annular aquaculture space 20, there is a feed guide cone ring wall 2. The upper outer ring contour of the feed guide cone ring wall 2 is integrally connected to the upper contour of the outer ring mesh wall 7. The lower inner ring contour of the feed guide cone ring wall 2 and the inner ring wall 8 form an annular feed outlet 5. The feed on the upper surface of the feed guide cone ring wall 2 will automatically slide downwards at an angle under the action of gravity and leak down into the annular aquaculture space 20 through the annular feed outlet 5.
[0023] like Figure 3 and 4 A rotating shaft 1 is coaxially fixedly connected to the upper end of the disc-shaped float section 9. The upper end of the rotating shaft 1 is rotatably mounted on the end of a float support arm 18 via a bearing. The lower part of each annular disc-shaped photovoltaic power generation platform 30 is fixedly supported on several float support arms 18. A structural feed funnel 17 is fixedly connected to the end of the float support arm 18. The lower end of the structural feed funnel 17 is a flat feed tube 12. A first strip plate 22a and a second strip plate 22b are integrally provided along the length direction on the two long sides of the lower end of the flat feed tube 12. The lower contours of the first strip 22a and the second strip 22b slide or gap with the upper surface of the feed guide cone ring wall 2. A feed accumulation trough 23 is formed between the first strip 22a and the second strip 22b along the length direction. The lower end of the flat feed pipe 12 is connected to the feed accumulation trough 23. When manual feeding is required, the feeding nozzle 16 at the lower end of the feed feeder 15 puts a predetermined amount of feed into the structural feed funnel 17. The feed entering the structural feed funnel 17 leaks down through the flat feed pipe 12 and accumulates at the feed accumulation trough 23.
[0024] Several scraping tips 4 are fixedly arranged in a circular pattern along the axis on the upper surface of the feed guide cone ring 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 scraping tips 4 pass through the feed accumulation trough 23 one by one, continuously scraping the fish feed in the feed accumulation trough 23. The scraped feed leaks down into the annular aquaculture space 20 under the action of gravity through the annular feed outlet 5, so that the feed is evenly sprinkled in the annular aquaculture space 20 along the circular path, so that the fish in the annular aquaculture space 20 can eat more evenly.
[0025] A central motor 13 is coaxially mounted below the axis of the ring-shaped photovoltaic power generation platform 30. The central motor 13 is fixedly supported and connected to several structural feed hoppers 17 around it via a structural bracket 14. The output shaft at the lower end of the central motor 13 is coaxially connected to a drum 11 wound with multiple layers of fabric tape 10a. Figure 6 As shown, the reel 11 extends several taut underwater straps 10 along the tangential direction. The underwater straps 10 can be made of nylon fiber. Each underwater strap 10 is fixedly connected to the outer circumferential surface of an outer ring mesh wall 7 at its end. The upper end of the disc-shaped float 9 is connected to the float support arm 18 via a torsion spring 3. In the initial state, the torsion spring 3 applies rotational torque to the disc-shaped float 9, causing the fish box float 15 to tend to rotate along the axis. The taut underwater straps 10 inhibit the fish box float 15 from rotating along the axis. When the reel 11 gradually extends the underwater straps 10, the fish box float 15 rotates along the axis under the drive of the torsion spring 3, thereby causing the underwater straps 10 to gradually wrap around the outer circumferential surface of the outer ring mesh wall 7, thus closing the mesh 6 on the outer ring mesh wall 7.
[0026] A feed feeder 15 is fixedly installed above the central motor 13 via a structural bracket 14; the feed nozzle 16 at the lower end of the feed feeder 15 corresponds to the receiving port of the structural feed funnel 17.
[0027] Working Principle: Under normal aquaculture conditions, several fish box floats 15 float in the water, and the portion of each fish box float 15 below the feed guide cone ring wall 2 is submerged in water, ensuring that the annular aquaculture space 20 is always filled with water and fish. Simultaneously, the fish box floats 15 support the annular photovoltaic power generation platform 30. Because this device is floating, the draft of each fish box float 15 remains stable regardless of water level changes. Therefore, the fish in the annular aquaculture space 20 can always move in the water. At the same time, the water in the annular aquaculture space 20 exchanges with the water in the surrounding water area in real time through the mesh 6 on the outer ring mesh wall 7, allowing fish excrement in the annular aquaculture space 20 to be discharged smoothly, while the surrounding water area... Small fish and shrimp can pass through the mesh 6 to reach the annular aquaculture space 20 to feed on the fish being raised, while also sharing oxygen. The mesh 6 on the outer ring wall 7 also prevents the fish raised in the annular aquaculture space 20 from being preyed upon by larger carnivorous fish in the surrounding waters. Because the annular aquaculture space 20 restricts the fish's feeding area, the fish's foraging range is concentrated, leading to food shortages under natural conditions. Therefore, additional feed is required. During the process of supplementing feed, the feed put into the annular aquaculture space 20 can easily escape outside the annular aquaculture space 20 due to the fish's activity and disturbance, resulting in feed waste. To solve this problem, the solution in this plan addresses this process 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 funnel 17. The feed entering the structural feed funnel 17 leaks down through the flat feed pipe 12 and accumulates in the feed accumulation trough 23. When the fish box float 15 is not rotating, the feed accumulated in the feed accumulation trough 23 cannot overflow smoothly and cannot slide smoothly into the annular aquaculture space 20.
[0029] At this time, the central motor 13 is controlled to gradually lead out the underwater strapping 10 wound on the drum 11. The fish box float 15 rotates one revolution along the axis under the drive of the torsion spring 3, so that the underwater strapping 10 gradually winds around the outer circumference of the outer ring mesh wall 7, thereby closing the mesh 6 on the outer ring mesh wall 7. At the same time, as the fish box float 15 rotates one revolution around its own axis, several scraping tips 4 pass through the feed accumulation trough 23 one by one, continuously scraping the fish feed in the feed accumulation trough 23. The scraped feed is then subjected to gravity. The feed is discharged into the annular aquaculture space 20 through the annular feed outlet 5, so that the feed is evenly distributed in the annular aquaculture space 20 along the circular path, so that the fish in the annular aquaculture space 20 can eat more evenly. At the same time, since the mesh 6 on the outer ring mesh wall 7 is surrounded and blocked by the underwater straps 10, the feed scattered in the annular aquaculture space 20 will not escape out of the annular aquaculture space 20 through the mesh 6 on the outer ring mesh wall 7 due to the movement and disturbance of the fish, thus avoiding the problem of feed waste.
[0030] After a certain period of time, once the feed scattered in the annular aquaculture space 20 is consumed, the central motor 13 is controlled to force the drum 11 to wind and recycle the underwater strap 10. This causes the fish box float 15 to overcome the torsion spring 3 and rotate back to its initial state under the pull of the underwater strap 10. At this time, the water in the annular aquaculture space 20 and the water in the surrounding water area are reconnected through the mesh 6 on the outer ring mesh wall 7, restoring normal aquaculture status.
[0031] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
