[0002] By using solar cells, solar energy can be directly converted into electrical energy. In a fishery-solar complementary project, a photovoltaic panel array is erected above the water surface of a fishpond or other water areas. The photovoltaic panel receives sunlight. When sunlight shines on the solar cell, electrons will be excited to generate an electric current. The generated electrical energy can be used to be incorporated into the power grid or for surrounding use. At the same time, the water area under the photovoltaic panel can be normally used for aquaculture of aquatic products such as fish and shrimps, forming a pattern of "generating electricity above and raising fish below". When constructing the photovoltaic array, a photovoltaic cable laying device for a fishery-solar complementary water area is required.

[0034] The embodiments of the present invention provide a device for laying a photovoltaic cable in a fishery-solar complementary water area, as Figures 1 to 7As shown, it includes a floating platform 8, a floating platform movement control mechanism, a cable winding and unwinding mechanism installed on the floating platform 8, and a cable laying mechanism. A plurality of floating cylinders 9 are fixed to the bottom of the floating platform 8; the cable winding and unwinding mechanism includes a bracket 12 fixed to the floating platform 8 and a winding disc 13 rotatably installed on the bracket 12, and the winding disc 13 is used for winding the cable; the cable laying mechanism includes an electric turntable 10 installed on one side of the bracket 12, a lifting assembly installed on the electric turntable 10, a first bracket 16 installed on the top of the lifting assembly, and a second bracket 17 parallel to and above the first bracket 16, and the first bracket 16 and the second bracket 17 are connected by a telescopic and adjustable connection assembly. The first bracket 16 and the second bracket 17 are both horizontally arranged U-shaped frames, and a plurality of guide wheels 25 are respectively rotatably installed in the U-shaped grooves of each bracket. The plurality of guide wheels 25 on each bracket are evenly distributed at equal intervals in a straight line, and the guide wheels on the two brackets correspond to each other and rotate in opposite directions; a transmission assembly for driving the guide wheels 25 on the first bracket 16 and the second bracket 17 to rotate in opposite directions is provided between the first bracket 16 and the second bracket 17. The transmission assembly is connected to the first bracket 16 and the second bracket 17. The transmission assembly includes a first gear 31, a second gear 32, a transmission belt 30, a tensioning assembly, and two belt pulleys 28. The first gear 31 and the second gear 32 are both rotatably arranged on the side wall of the first bracket 16, and the first gear 31 is fixedly connected to the adjacent guide wheel 25 on the first bracket 16. One of the belt pulleys 28 is fixed to the second gear 32, and the other belt pulley 28 is fixed to the adjacent guide wheel 25 on the second bracket 17. The transmission belt 30 is sleeved on the two belt pulleys 28; the tensioning assembly is arranged on the first bracket 16, and the tensioning assembly is used for tensioning the transmission belt 30.

[0035] Due to the action of the tensioning assembly, the transmission belt 30 can always have sufficient friction with the two belt pulleys 28, thereby ensuring the transmission effect. At the same time, through the adjustment of the tensioning assembly, when the distance between the first bracket 16 and the second bracket 17 changes, the cable can still be conveyed, enabling the device to lay cables of various sizes.

[0036] In the embodiment, as Figure 6 and Figure 7As shown in the figure, the tensioning assembly includes an adjusting wheel 33, a slider 35, a second spring 36, and a chute 37. The chute 37 is horizontally opened on the top surface of the closed end of the first bracket 16. The slider 35 is slidably arranged in the chute 37. The second spring 36 is located in the chute 37, with one end fixedly connected to the inner wall of the chute 37 and the other end fixedly connected to the slider 35. The adjusting wheel 33, the first gear 31, and the second gear 32 are arranged on the same side. The rotating shaft of the adjusting wheel 33 is rotatably connected to the side wall of the slider 35, and the transmission belt 30 is sleeved on the adjusting wheel 33. After sleeving, the adjusting wheel 33 and the two belt pulleys 28 are arranged in a triangular shape within the transmission belt 30. By sliding between the slider 35 and the chute 37, the position of the adjusting wheel 33 is adjusted. When the slider 35 slides away from the open end of the bracket, it will drive the adjusting wheel 33 to move away from the open end of the bracket. After the adjusting wheel 33 moves, it will be farther away from the belt pulley. Under the traction of the transmission belt 30, the distance between the two belt pulleys 28 will decrease. When the slider 35 slides towards the open end of the bracket, it will drive the adjusting wheel 33 to move towards the open end of the bracket. After the adjusting wheel 33 moves, it will be closer to the belt pulley. Under the action of the transmission belt 30, the distance between the two belt pulleys 28 will increase, so that the device can adapt to cables of different lengths and different sizes. As Figure 5 As shown in the figure, two tensioning wheels 29 are arranged at the top of the first bracket 16 and the bottom of the second bracket 17. The tensioning wheels 29 are used to ensure the wrap angle of the transmission belt 30 and the belt pulley 28. As Figure 4 As shown in the figure, a second motor 27 is provided on the side wall of the second bracket 17, and the output shaft of the second motor 27 is fixed to the nearest guide wheel 25 on the second bracket 17.

[0037] In the embodiment, as Figure 1 As shown in the figure, the floating platform movement control mechanism includes a first fixing plate 1, a belt 5, a second fixing plate 6, and a first motor 4 fixed on the first fixing plate 1. A support plate 3 is fixedly installed on the top of the first fixing plate 1. Two pressing wheels 2 are rotatably installed between the first fixing plate 1 and the support plate 3, and both pressing wheels 2 are rotatably connected to the support plate 3. The first motor 4 is fixed on the top of the support plate 3, and the output shaft of the first motor 4 is fixed to one of the adjacent pressing wheels 2. A support wheel 7 is rotatably installed on the second fixing plate 6. The two ends of the belt 5 are fixedly connected to the two side walls of the floating platform 8, and the belt 5 passes through the surface of the support wheel 7 and the gap between the two pressing wheels 2, and drives the pressing wheel 2 fixed to the first motor 4 and the support wheel 7. The floating platform 8 is fixed on the belt 5. When the first motor 4 works, it drives the belt 5 to move, and the floating platform 8 can be pulled to move during the movement. When the floating platform 8 moves to the other side of the pond, the first motor 4 can be rotated in the reverse direction to control the floating platform 8 to move in the reverse direction.

[0038] In the embodiment, as Figures 2 to 4As shown, the lifting assembly includes a sleeve 11, a sleeve rod 15, and a second piston 26. The sleeve 11 is fixed to the top of the electric turntable 10. The second piston 26 is slidably disposed within the sleeve 11. The sleeve rod 15 is fixed to the top of the second piston 26 and is fixed to the first bracket 16. The lifting assembly further includes a hydraulic control mechanism. The hydraulic control mechanism is mounted between the electric turntable 10 and the cable winding and unwinding mechanism by two support plates 18. The hydraulic control mechanism includes a hydraulic push rod 19, a cylinder body 20, and a first piston 21. The first piston 21 is slidably disposed within the cylinder body 20, and the first piston 21 is fixed to the telescopic end of the hydraulic push rod 19. The piston chamber of the cylinder body 20 is communicated with the piston chamber at the lower part of the sleeve 11 through an oil supply pipe 14. When the switch of the hydraulic push rod 19 is turned on, the hydraulic push rod 19 pushes the first piston 21 to move when working, and then injects the hydraulic oil inside the piston chamber of the cylinder body 20 into the piston chamber at the lower part of the sleeve 11 through the oil supply pipe 14. The hydraulic oil entering the sleeve 11 can push the second piston 26 to rise, and then cooperate with the sleeve rod 15 to realize the overall height adjustment of the first bracket 16 and the second bracket 17.

[0039] In the embodiment, as Figure 5 and Figure 6 shown, the telescopic connection assembly includes a connection sleeve 23, a connecting rod 24, a first spring 34, and two connection blocks 22. The two connection blocks 22 are respectively rotatably disposed on the side walls of the first bracket 16 and the second bracket 17. The connection sleeve 23 is fixed to one of the connection blocks 22, the connecting rod 24 is fixed to the other connection block 22, one end of the first spring 34 is fixed to the inner wall of the connection sleeve 23, and the other end of the first spring 34 is fixed to the end of the connecting rod 24. The positions of the two connection blocks 22 of the same set of telescopic link assemblies do not correspond, so that the connection sleeve 23 and the connecting rod 24 are in an inclined state to connect the first bracket 16 and the second bracket 17. Through the sliding between the connecting rod 24 and the connection sleeve 23, and the pulling force provided by the first spring 34, the first bracket 16 and the second bracket 17 are close to each other, and then through the extrusion of the guide wheels 25 on the first bracket 16 and the second bracket 17, the fixation of the cable is ensured.

[0040] When the present invention is in use, first, the first fixing plate 1 and the second fixing plate 6 are fixedly installed on both sides of the pond, and then the belt 5 is tensioned by the support wheels 7. At the beginning, the floating platform 8 is located on one side of the pond. At this time, the end of the cable wound on the winding disc 13 is drawn out, and then the cable is passed through between the first bracket 16 and the second bracket 17. Finally, the cable passes out from the end of the first bracket 16 and the second bracket 17 away from the sleeve rod 15. Then, through the sliding between the connecting rod 24 and the connection sleeve 23, and the pulling force provided by the first spring 34, the first bracket 16 and the second bracket 17 are close to each other, and then through the extrusion of the guide wheels 25 on the first bracket 16 and the second bracket 17, it is ensured that the cable can always move along between the first bracket 16 and the second bracket 17.

[0041] When laying cables, by turning on the switch of the hydraulic push rod 19, when the hydraulic push rod 19 works, it pushes the first piston 21 to move. Then, the hydraulic oil inside the cylinder body 20 is injected into the sleeve 11 through the oil supply pipe 14. The hydraulic oil entering the sleeve 11 can push the second piston 26 to rise, and then cooperate with the sleeve rod 15 to realize the height adjustment of the first bracket 16 and the second bracket 17. Through the action of the electric turntable 10, the positions of the ends of the first bracket 16 and the second bracket 17 (i.e., the positions of the cable ends) can be changed on the horizontal plane, and the cable ends can be adjusted above the cable trough, so that the cable can reach the release height, and the protruding cable ends are placed in the cable trough of the cable to be laid, and the corresponding fixing devices (such as clamps, bolts) are used to limit the ends of the cable to prevent the cable from moving synchronously when displaced later.

[0042] During the cable laying process, turn on the switch of the first motor 4. When the first motor 4 works, it drives one of the extrusion wheels 2 to rotate in cooperation with the extrusion of the other extrusion wheel 2 and the tension of the support wheel 7, so that the belt 5 moves, and then drives the floating platform 8 to move on the water surface to lay the cable in the cable trough reserved by the photovoltaic bracket. Turn on the switch of the second motor 27. When the second motor 27 works, it drives the guide wheel 25 to rotate. Through the rotation of the guide wheel 25, the transmission of the cable is realized, and then the cable can continuously output from the ends of the first bracket 16 and the second bracket 17. Since the cable end is already above the cable trough before releasing the cable, therefore, with the output of the cable and the movement of the floating platform 8 in cooperation, the cable can be placed in the cable trough;

[0043] Since different cables have different diameters, when using this device to lay cables of other diameters, the position of the adjusting wheel 33 can be adjusted by the sliding between the slider 35 and the chute 37. When the adjusting wheel 33 moves, the distance between the two belt pulleys 28 can be increased or decreased, so that this device can be adapted to cables of different diameters and different sizes.

[0044] Therefore, during the rotation of one of the belt pulleys 28, it can drive the other belt pulley 28 to rotate through the transmission belt 30 to drive the second gear 32 to rotate, and cooperate with the first gear 31 to realize the rotation of the guide wheel 25 on the first bracket 16, and then realize the cable conveying work.

[0045] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some or all of the technical features; and these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
