Description

Technical Field

[0001] The utility model relates to the field of photovoltaic power generation, in particular to a floating fishing-photovoltaic complementary system net collecting device. Background Art

[0002] The fish-light complementary system is generally a combination of fixed brackets and pond farming. This method requires piling in the original pond, which causes waste, and the fish-light complementary mode cannot be carried out in deep water. At the same time, due to the existence of fixed brackets, it is not possible to use dragnet fishing, and only lure fishing can be used, and the fishing rate is not high.

[0003] Another form of fish-solar complementarity is to combine photovoltaic modules with cages. Cage farming is a high-density farming method that uses fishing nets to confine farmed organisms such as fish and shrimp to a fixed area in a river. Cages generally contain a buoy floating on the water surface, a counterweight sunk in the water, and a fishing net that surrounds a farming area. In the season when farmed organisms such as fish and shrimp mature, the cages need to be put away to catch the fish in them. When the cages are put away, the center of the bottom fishing net sags, resulting in a low center and high surroundings, and fish and shrimp are concentrated in the middle of the cage, which brings inconvenience to fishing. Utility Model Content

[0005] The floating fishing-photovoltaic complementary system net-collecting device is suitable for collecting net cages, which include a floating platform provided with a photovoltaic component array, a side net connected to the floating platform at the upper end, a counterweight device arranged at the lower end of the side net, and a bottom net covering the area surrounded by the counterweight device. The side net and the bottom net surround a breeding area. The net-collecting device includes: a plurality of first rope-collecting devices, which are evenly distributed on the floating platform along the circumferential direction; a plurality of first cables, which are evenly distributed along the circumferential direction of the net cage, the lower end of each first cable is connected to the counterweight device, and the upper end of each first cable has a first rope-collecting device; a second rope-collecting device, which is arranged on the floating platform; a middle rope-binding component, which is arranged along the central axis of the counterweight device; and a plurality of second cables, which are evenly connected to the counterweight device, one end of each second cable is fixedly connected to the counterweight device, and extends from below the bottom net to the middle rope-binding component, and can movably pass through the middle rope-binding component and then extend upward to the second rope-collecting device.

[0006] In some embodiments, the first rope collection device includes a first traction wheel and a first motor driving the first traction wheel to rotate, and the first cable is wound around the first traction wheel.

[0007] In some embodiments, the second rope collection device includes a second traction wheel and a second motor driving the second traction wheel to rotate, and the second cable is wound around the second traction wheel.

[0008] In some embodiments, the middle tie rope component includes through holes or fixed pulleys uniformly arranged along the circumferential direction, and the second cable passes through the through holes or the fixed pulleys.

[0009] In some embodiments, the floating platform includes a floating body and a rigid support that continuously extends around the photovoltaic component array, the floating body is connected to the rigid support, and the first rope collection device is evenly arranged on the rigid support along the extension direction.

[0013] The beneficial effect of the utility model is that when the net cage is unfolded, the length of the second cable is fully released, and the bottom net is not constrained by the second cable and can be spread out. After the first cable is pulled to fully close the net cage, the second cable can be folded up, so that the section of the second cable located below the bottom net holds up the bottom net, causing the bottom net to be high in the middle and low around, so that fish and shrimp gather at the edge of the bottom net, which is convenient for fishing. If there is no second cable to hold up the net from the bottom, even if the counterweight device is lifted up and contacts the floating platform, the center of the bottom net is still some distance away from the water surface, resulting in the fish being in the center of the bottom net, making fishing inconvenient. BRIEF DESCRIPTION OF THE DRAWINGS

[0014] Figure 1 The figure schematically shows a floating fishing-photovoltaic complementary system net collecting device according to an embodiment of the utility model. DETAILED DESCRIPTION

[0015] The following embodiments of the technical solution of the present application will be described in detail in conjunction with the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present application, and are therefore only used as examples, and cannot be used to limit the scope of protection of the present application.

[0016] When the net cage of the fish-light complementary system is folded up, the sagging effect of the bottom fishing net causes the middle part to be low and the surrounding parts to be high, so that fish and shrimp and other farmed animals are concentrated in the middle of the bottom fishing net, which brings inconvenience to the fishing operation. In order to solve the problems of the prior art, the present invention provides a floating fish-light complementary system net folding device.

[0017] Please refer to Figure 1The floating fishing-photovoltaic complementary system net-collecting device is suitable for collecting the net cage, which includes a floating platform 11 provided with a photovoltaic module array 2, a side net (not shown in the figure) connected to the floating platform 11 at the upper end, a counterweight device 12 provided at the lower end of the side net, and a bottom net (not shown in the figure) covering the area surrounded by the counterweight device 12. The side net and the bottom net surround a breeding area. The buoyancy of the floating platform 11 can withstand the gravity of the entire system, so that the system can float on the water surface, and surround a breeding space that can prevent aquatic products from escaping through the net immersed in the water. The floating platform 11 and the counterweight device 12 constitute the frame of the net cage, which props up the side net and the bottom net so that they can be fully unfolded.

[0018] In one embodiment, please refer to Figure 1 The floating platform 11 includes a floating body 111 and a rigid support 112 that extend continuously around the photovoltaic module array 2. The floating body 111 is connected to the rigid support 112. The rigid support 112 is evenly provided with a first rope collection device 31 ( Figure 1 Only one first rope collecting device is schematically shown in the figure). The floating body 111, the rigid support 112 and the counterweight device 12 are in a closed shape that extends continuously around the central axis of the net box. For example, the floating body 111, the rigid support 112 and the counterweight device 12 can be a circular ring, a square, a regular hexagon or a regular triangle. Preferably, the floating body 111, the rigid support 112 and the counterweight device 12 extend along a circular ring. Under the same surface area, the cylindrical net box has a larger volume, which is more conducive to saving net clothes.

[0019] In one embodiment, the float 111 may be made of a light-density material that can float on water, for example, the float 111 may be an inflatable air film, an inflatable air bag, or a buoyancy tube, etc. The inflatable air film or the inflatable air bag may have an outer layer woven from a high-strength flexible fiber material to improve the strength of the air film or the air bag. The buoyancy tube may be formed by welding together a plurality of sections of polyethylene blow-molded pipes.

[0020] In one embodiment, the counterweight device 12 can be made of, for example, metal material or non-metal material. The counterweight device 12 has sufficient weight to sink underwater, straighten and unfold the net, and the sinker can also lower the center of gravity of the floating fishing-light complementary system to prevent the fishing-light complementary system from tipping over.

[0021] In one embodiment, the net can be made of a polymer material such as polyethylene, nylon or aramid.

[0022] Please refer to Figure 1The net collecting device includes a plurality of first rope collecting devices 31, a plurality of first cables 32, a second rope collecting device, a middle rope tying component 33 and a plurality of second cables 34. The first rope collecting devices 31 are evenly distributed on the floating platform 11 along the circumferential direction. The plurality of first cables 32 are evenly distributed along the circumferential direction of the net box, the lower end of each first cable 32 is connected to the counterweight device 12, and the upper end of each first cable 32 has a first rope collecting device 31. The second rope collecting device is arranged on the floating platform 11. The middle rope tying component 33 is arranged along the central axis of the counterweight device. The plurality of second cables 34 are evenly connected to the counterweight device, one end of each second cable 34 is fixedly connected to the counterweight device 12, and extends from the bottom of the bottom net to the middle rope tying component 33, and can movably pass through the middle rope tying component 33 and then extend upward to the second rope collecting device.

[0023] When the first rope-collecting device 31 pulls the first cable 32, the counterweight device 12 can be lifted, so that the net cage is gathered and shallowed, which is convenient for fishermen to catch mature fish and shrimp in the net cage during the harvest season. Since the first cable 32 has to hang the heavy counterweight device 12, the first cable 32 needs to have sufficient tensile strength. Preferably, the first cable 32 is a steel wire rope.

[0024] When the net cage is unfolded, the length of the second cable 34 is fully released, and the bottom net is not constrained by the second cable 34 and can be spread out. When the first cable 32 is pulled to fully close the net cage, the second cable 34 can be tightened so that the section of the second cable 34 located below the bottom net lifts up the bottom net, causing the bottom net to be high in the middle and low around, so that fish and shrimp gather at the edge of the bottom net, which is convenient for fishing. If there is no second cable 34 to hold up the net from the bottom, even if the counterweight device 12 is raised to contact the floating platform 11, the center of the bottom net is still a distance away from the water surface, resulting in the fish being in the center of the bottom net, which brings inconvenience to the fishing operation. The second cable 34 is mainly used to tighten the bottom net, so its strength is allowed to be lower than that of the first cable 32. Therefore, in one embodiment, the second cable 34 can be a polyethylene rope, a nylon rope, an aramid rope, a steel wire rope, and a composite rope, or a combination of two or more.

[0025] In one embodiment, the middle rope tie component 33 can be a component made of metal material and has a certain weight. The middle rope tie component 33 has a function of dropping the second cable 34 to prevent the second cable 34 from drifting in the water.

[0026] In some embodiments, please refer to Figure 1The first rope collecting device 31 includes a first traction wheel 311 and a first motor 312 that drives the first traction wheel 311 to rotate, and the first cable 32 is wound around the first traction wheel 311. Each first rope collecting device 31 pulls a first cable 32. The first motor 312 rotates forward and reversely to pull and release the first cable 32, so as to realize the folding and unfolding of the net cage. The first motor 312 can be equipped with a reducer to increase the torque for pulling the first cable 32. When the net is closed, each first rope collecting device 31 can be started one after another. For example, assuming that the first cable 32 is 10m long, when the net needs to be closed for fishing, the first rope collecting device 31 numbered 1 is first used to pull the first cable 32 pulled by it by 0.5m; then the first rope collecting device 31 numbered 2 is started to pull the first cable 32 pulled by it by 0.5m; then the other first cables 32 are sequentially lifted by 0.5m, and the entire counterweight device 12 is lifted by 0.5m. Then repeat the above steps until the cage shrinks to a predetermined position.

[0027] In some embodiments, please refer to Figure 1 The rope collecting device further includes a plurality of guide pulleys 313, which are evenly fixed on the rigid support 112 along the extension direction of the rigid support 112. The first cable 32 passes around the guide pulleys 313 and then leads to the first rope collecting device 31. For example, the first cable 32 is wound around the first traction wheel 311.

[0028] In some embodiments, please refer to Figure 1 The second rope collecting device 35 includes a second traction wheel 351 and a second motor 352 that drives the second traction wheel 351 to rotate, and the second cable 34 is wound around the second traction wheel 351. The second traction wheel 351 can be provided with a plurality of rope grooves, and a plurality of second cables 34 are respectively wound in the corresponding rope grooves. The second rope collecting device 35 can be installed on a stable floating body separately provided in the middle of the floating platform 11, or it can be provided on the rigid support 112. For the latter, a longer second cable 34 is required, and a guide wheel is provided in the middle of the floating platform 11.

[0029] In some embodiments, the middle tying rope component 33 includes through holes or fixed pulleys uniformly arranged along the circumferential direction, and the second cables 34 pass through the through holes or fixed pulleys. Each second cable 34 passes through a through hole or fixed pulley, so that the middle tying rope component 33 can slide freely on the second cables 34.

[0030] The above are only some embodiments of the present invention. For those skilled in the art, several modifications and improvements can be made without departing from the inventive concept of the present invention, which all belong to the protection scope of the present invention.
