[0002] A pumped-storage power station is an energy storage device with a power regulation function. Its characteristics are upper and lower reservoirs with different elevations and a large water area. The reservoir of the pumped-storage power station is formed by building a retaining dam in a mountain depression according to the terrain, so the reservoir basin has an inverted trapezoidal cross-section that is larger at the top and smaller at the bottom due to the shape of the mountain. How to make full use of the reservoir surface of the pumped-storage power station and give play to greater engineering economic and social benefits is a research topic worthy of study, and there is no relevant mature technology yet. For example, using the upper and lower reservoir surfaces for power generation can not only increase power generation but also reduce the water evaporation loss caused by partial blocking of sunlight on the water surface. Summary of the Invention

[0003] The technical problem to be solved by the utility model is to provide a slope-anchored water surface photovoltaic device that adapts to the characteristics of the reservoir basin and uses the upper and lower reservoir surfaces for photovoltaic power generation.

[0004] To solve the above technical problem, the technical solution adopted by the utility model is: a slope-anchored water surface photovoltaic device, including a plurality of anchor points arranged at the bottom of the bank slope or reservoir basin, and further including floating capsules arranged on the reservoir surface. A photovoltaic panel power generation device is arranged on the floating capsules. A plurality of connection points are arranged on the outer side of the floating capsules. The connection points are connected to the anchor points through a traction positioning mechanism. The traction positioning mechanism includes a housing. One side of the housing is hinged to the floating capsule. A through hole for the positioning rope to pass through is arranged on the housing. A rotating shaft is rotatably installed in the housing through a bearing. A rope wheel group for winding the positioning rope is arranged on the rotating shaft. One end of the positioning rope is wound on the rope wheel group, and the other end passes through the through hole on the housing and is connected to the anchor point. A rope retracting mechanism is arranged at the end of the rotating shaft for the rotating shaft to return to its original position.

[0005] In a preferred solution, the rope retracting mechanism includes a spring housing arranged around the rotating shaft. The spring housing is fixed on the housing. A spring is arranged around the rotating shaft in the spring housing. One end of the spring is connected to the rotating shaft, and the other end is connected to the spring housing.

[0006] In a preferred solution, two groups of the rope retracting mechanisms are arranged, respectively at both ends of the rotating shaft.

[0008] In a preferred solution, the photovoltaic panel power generation device includes photovoltaic panels, which are electrically connected to a current collector and an inverter in sequence. The inverter is electrically connected to a transformer on the shore through a cable.

[0009] The slope-anchored floating photovoltaic device provided by the utility model has the following beneficial effects:

The traction positioning mechanism keeps the positioning rope in a tightened state through the energy storage of the set clock spring, and can automatically store the excess positioning rope into the rope pulley group. When the water level rises or falls, the extended length of the positioning rope is automatically adjusted to ensure that the floating bladder basically remains in the center of the reservoir.

Specific implementation mode

[0023] The technical solution of the present utility model will be further described below in conjunction with the accompanying drawings.

[0024] A slope-anchored floating photovoltaic device, as Figures 1 to 7 shown, includes a plurality of anchor points 100 arranged at the bottom of the bank slope or reservoir basin, and further includes a floating bladder 200 arranged on the reservoir surface. A photovoltaic power generation device 300 is arranged on the floating bladder 200. A plurality of connection points are arranged on the outer side of the floating bladder 200. The connection points are connected to the pull ring of the anchor point 100 through a pulling and positioning mechanism 400, so that the floating bladder 200 is basically maintained in the center of the reservoir.

[0025] As Figures 5 to 7 shown, the pulling and positioning mechanism 400 includes a housing 410. One side of the housing 410 is hinged to the floating bladder 200. A through hole for the positioning rope 420 to pass through is arranged on the housing 410. The rotating shaft 430 is rotatably installed in the housing 410 through a bearing 470. A rope pulley group 440 for winding the positioning rope 420 is arranged on the rotating shaft 430. One end of the positioning rope 420 is wound on the rope pulley group 440, and the other end passes through the through hole on the housing 410 and is connected to the pull ring of the anchor point 100. A rope winding mechanism 450 is arranged at the end of the rotating shaft 430 for the rotating shaft 430 to rotate and reset.

[0026] Two sets of rope winding mechanisms 450 are arranged, respectively arranged at both ends of the rotating shaft 430. The rope winding mechanism 450 includes a spiral spring housing 451 arranged around the rotating shaft 430. The spiral spring housing 451 has a cylindrical structure so that the rotating shaft 430 can pass through. The spiral spring housing 451 is fixed in the housing 410. A spiral spring 452 is arranged around the rotating shaft 430 in the spiral spring housing 451. One end of the spiral spring 452 is connected to the rotating shaft 430, and the other end is connected to the spiral spring housing 451. The connection can be fixed by means of riveting and welding.

[0027] By setting the energy storage of the spiral spring 452, the tension state of the positioning rope 420 is maintained, and the redundant positioning rope 420 can be automatically stored in the rope pulley group 440. When the water level rises or falls, as Figures 2 to 4 shown, the extended length of the positioning rope 420 is automatically adjusted to ensure that the floating bladder 200 is basically maintained in the center of the reservoir.

[0028] A connection ring 210 is provided at the connection point on the outer side of the floating bladder 200, and an installation ring 460 connected to the connection ring 210 is provided on the outer side of the pulling and positioning mechanism 400, which facilitates reliable connection with the floating bladder 200 and can adjust the angle relative to the floating bladder 200 at the same time.

[0029] In this embodiment, the photovoltaic panel power generation device 300 includes a photovoltaic panel 310, the photovoltaic panel 310 is electrically connected to a bus collector 320 and an inverter 330 in sequence, and the inverter 330 is electrically connected to a transformer 350 on the shore through a cable 340.

[0030] A number of anchor points 100 are arranged at appropriate positions on the slope or bottom of the reservoir basin. The positioning ropes 420 equipped on each anchor point are reasonably selected with appropriate margins according to the maximum lengths required according to the distances from the slope to the center of the water surface. The maximum rope capacity of the rope pulley group 440 should also consider the length of the positioning rope 420. The energization magnitudes of the respective spring winders 452 cannot be set according to a certain value, but are set according to the actual situation. The principle is that under the pulling force of the 420 determined by the energization of the respective spring winders 452, it is ensured that the floating bladder 200 can be maintained in the center of the reservoir at various different water level elevations. In this way, not only can the optimal power generation effect be ensured, but also the floating bladder 200 can be prevented from being damaged due to collision with the reservoir bank.

[0031] The working process of a slope-anchored water surface photovoltaic device is as follows:

[0032] When the water level in the reservoir basin is in the high water level state, a plurality of pulling and positioning mechanisms 400 are installed on the floating bladder 200, and then the floating bladder 200 is hoisted to the water surface by a hoisting device, or the floating bladder 200 is slid to the water surface by a winch device through a slideway arranged on the shore slope. Then, the positioning ropes 420 of the pulling and positioning mechanism 400 are pulled out and fixed on the pull rings of the anchor points 100. The photovoltaic panel 310 is laid on the floating bladder 200, and the photovoltaic panel 310 is electrically connected to the bus collector 320 and the inverter 330 in sequence. The water level of the reservoir basin is lowered to expose the anchor points above the water surface. The installation personnel take a boat to pull out the positioning ropes 420 of the respective pulling and positioning mechanisms 400 around the floating bladder 200 and then connect them to the pull rings of the corresponding anchor points 100 respectively. At this time, the floating bladder 200 is located in the middle of the reservoir basin. The water level of the reservoir basin is run up and down several cycles between the highest and lowest water levels. After problems occur, timely adjustment and repair are carried out. After debugging is error-free, it can be put into formal operation.

The protection scope of the present utility model shall be the technical solutions recorded in the claims, including the equivalent replacement solutions of the technical features in the technical solutions recorded in the claims. For those of ordinary skill in the art, other different forms of changes or modifications can be made on the basis of the above description. It is not necessary and impossible to enumerate all the implementation manners here, that is, the equivalent replacement improvements within this scope are also within the protection scope of the present utility model.
