[0002] Floating photovoltaic power stations usually refer to solar photovoltaic power generation facilities deployed on the water surface, also known as "floating photovoltaic" or "floating photovoltaic". The design of this power station allows photovoltaic panels to float on the surface of the water body, usually a lake, reservoir or ocean. This installation method has several potential advantages, such as saving land use and reducing water evaporation. It can also reduce the temperature of solar panels and improve power generation efficiency. When this project was put into use, it was found that a film was installed in the middle of the floating unit. The position of the film was lower than the pontoon module around the floating section, which made it very easy for water to accumulate on the surface of the film, and the accumulated water could not be discharged, which led to a larger overall weight of the floating unit and reduced its buoyancy.

[0036] Secondly, the present invention is described in detail with reference to the schematic diagram. When describing the embodiments of the present invention in detail, for the sake of convenience, the cross-sectional diagrams showing the device structure will not be partially enlarged according to the general scale, and the schematic diagrams are only examples, which should not limit the scope of protection of the present invention. In addition, in actual production, the three-dimensional dimensions of length, width and depth should be included.

[0037] Example 1

[0038] Reference Figure 1-Figure 2 , a floating photovoltaic power station drainage device is provided, comprising a floating island component 100, which is in a circular ring shape; an air film component 200, which is arranged inside the floating island component 100;

[0039] The air film component 200 is fixedly disposed inside the floating island component 100 , and photovoltaic equipment can be disposed on the air film component 200 and the floating island component 100 .

[0040] Furthermore, the floating island component 100 is composed of multiple groups of pontoon parts 101 connected end to end, and the pontoon part 101 is provided with an inner ring part 101a and an outer ring part 101b. The two ends of the multiple groups of pontoon parts 101 are connected and fixed to form the floating island component 100. The interiors of the inner ring part 101a and the outer ring part 101b are both hollow, so that the floating island component 100 composed of the pontoon parts 101 can float on the water surface. The inner ring part 101a and the outer ring part 101b are fixedly connected by a connecting part 101c, and the curvature of the inner ring part 101a and the outer ring part 101b are set by the same center of a circle, and the air film component 200 is fixedly arranged on the inner surface of the inner ring part 101a.

[0041] Furthermore, the air film component 200 includes a truss portion 201 and a film 202 arranged at the bottom of the truss portion 201; the edge of the film 202 is connected to the inner side of the floating island component 100, the truss portion 201 is fixedly arranged on the inner side of the floating island component 100, the film 202 is fixedly arranged at the bottom of the truss portion 201, the edge of the film 202 is fixedly connected to the inner side of the floating island component 100, and a photovoltaic device can be arranged on the top of the air film component 200.

[0042] Furthermore, the buoyancy chamber 101 is provided with a water inlet 101d corresponding to the edge of the film 202; the film 202 is inclined with a lower edge close to one side of the buoyancy chamber 101;

[0043] The truss part 201 includes a longitudinal long rod 502b201a and a transverse short rod 201b. The longitudinal long rod 502b201a is fixedly arranged on the inner side of the floating island component 100, and both ends thereof are fixedly connected to the pontoon part 101. Multiple groups of transverse short rods 201b are fixedly arranged on both sides of the longitudinal long rod 502b201a, and the ends of the multiple groups of transverse short rods 201b are fixedly connected to the pontoon part 101. The arrangement of the truss part 201 allows the film 202 to be divided into multiple cells. Through such division, when the amount of water accumulated on the film 202 exceeds the load-bearing capacity of the film 202, only a single cell of the film 202 will be damaged, thereby avoiding the overall rupture of the film 202.

[0044] The position of the longitudinal long rod 502b201a is higher than the connection height of the transverse short rod 201b and the buoyancy box part 101, so that after the film 202 is fixed, it is in an inclined state with a higher position close to the longitudinal long rod 502b201a and a lower position close to the edge of the buoyancy box part 101. A water inlet 101d is opened on the inner side of the inner ring 101a, and the lower edge of the film 202 is located below the water inlet 101d. Since the inner ring 101a is hollow, when water gathers on the surface of the film 202, its inclined state causes the water to be guided into the inner ring 101a, thereby reducing the damage to the film 202 caused by the weight of the water.

[0045] By setting the truss part 201 and the water inlet 101d, the film 202 is prevented from being damaged as a whole, and the water on the surface of the film 202 is drained into the pontoon part 101, further reducing the load-bearing capacity of the film 202 and reducing the damage to the film 202 when there is a lot of water in the floating unit.

[0046] Example 2

[0047] In the above embodiment, although the surface load of the film 202 is reduced, the water in the buoyancy tank 101 is not easy to discharge, which will cause the floating unit to be heavier and the buoyancy of the equipment to be insufficient;

[0048] Reference Figure 1-Figure 3 This embodiment is different from the first embodiment in that: a pumping pipe 300 is further provided in the buoyancy tank portion 101, and the pumping pipe 300 is connected to an external pumping device; and the connection points of multiple groups of buoyancy tank portions 101 can be connected;

[0049] The pumping pipe 300 is arranged in the inner ring member 101a, and the other end of the pumping pipe 300 extends out of the inner ring member 101a and is connected to the electric pumping equipment. In this embodiment, the pumping equipment can use a water pump, and the water pump can pump out the water in the inner ring member 101a through the pumping pipe 300. At the same time, connecting holes 101e are provided at both ends of the inner ring member 101a. The connecting holes 101e can allow the water in multiple groups of inner ring members 101a to flow, thereby avoiding excessive water in a single group of inner ring members 101a, causing the problem of overall imbalance of the equipment. At the same time, through such a setting, multiple groups of pontoon parts 101 can use the same pumping pipe 300 for pumping water, thereby reducing the setting of the drainage pipe 602 on the floating unit, and preventing the drainage pipe 602 from occupying too much area.

[0050] It also includes a drainage component 600, which includes a guide plate 601 disposed in the buoyancy tank portion 101, and a drainage pipe 602 disposed at the bottom of the guide plate 601, and the drainage pipe 602 extends out of the buoyancy tank portion 101;

[0051] A guide plate 601 is fixedly provided on the inner wall of the inner ring 101a. The guide plate 601 is located below the drain port. The water extraction pipe 300 is provided above the guide plate 601. The cross section of the guide plate 601 is funnel-shaped. A plurality of drainage pipes 602 are fixedly provided at the bottom of the guide plate 601. The plurality of drainage pipes 602 extend from the side of the inner ring 101a to the outside thereof, so that the water entering the inner ring 101a is guided by the guide plate 601 and then discharged by the drainage pipe 602. A check valve may be provided in the drainage pipe 602 to prevent water from flowing back into the inner ring 101a.

[0052] In daily state, the drain pipe 602 can be used to drain the water from the inner ring 101a first. When the water intake is greater than the discharge speed of the drain pipe 602, the external pumping equipment can be started to pump water from the inner ring 101a.

[0053] The rest of the structure is the same as that of Example 1.

[0054] By disposing the drainage component 600 and the water suction pipe 300, the water in the inner ring member 101a can be discharged in two ways, thereby avoiding the problem of increased weight of the floating unit and reduced buoyancy.

[0055] Example 3

[0056] Reference Figure 1-Figure 6 , this embodiment is different from the above embodiments in that: it also includes a trigger component 500, which is arranged in the buoyancy box part 101; the buoyancy box part 101 is provided with a switch 400, and the switch 400 can control the opening and closing of the external pumping equipment;

[0057] Wherein, the trigger component 500 can resist the switch 400;

[0058] A set of trigger components 500 can be set in multiple groups of interconnected inner ring parts 101a, and the switch 400 is set at the top inside the inner ring part 101a, and the switch 400 is electrically connected to the external pumping equipment, which can control the opening and closing of the external pumping equipment. When the water intake into the inner ring part 101a is greater than the drainage speed of the drain pipe 602, the continuously increasing water volume can cause the trigger component 500 to move, and then cause it to resist the switch 400, starting the external pumping equipment, so that the external pumping equipment can pump out the water in the inner ring part 101a.

[0059] Furthermore, the trigger component 500 includes a floating plate 501 disposed in the floating box portion 101, and a connecting component 502 is disposed on the top of the floating plate 501;

[0060] The floating plate 501 can float on the water, and can drive the connection component 502 to rise and fall, and the connection component 502 can contact the switch 400 when rising;

[0061] The connecting component 502 is slidably connected to the inside of the inner ring 101a, and a floating plate 501 is connected to the bottom of the connecting component 502. In normal conditions, the floating plate 501 is located above the water inlet 101d. When there is a large amount of water in the inner ring 101a, the floating plate 501 can float on the water surface and rise with the continuous increase in water, thereby driving the connecting component 502 to rise. After the connecting component 502 rises, it contacts the switch 400, turning on the external pumping equipment to pump out the water in the inner ring 101a.

[0062] Furthermore, the trigger component 500 is further provided with a limiter 504, and the limiter 504 is provided in the buoyancy chamber 101; the connecting assembly 502 is provided in the limiter 504;

[0063] The stopper 504 includes a fixing plate 504a fixedly mounted on the top of the inner ring 101a. The fixing plate 504a is in a U-shape and has a blocking block at the bottom. The fixing plate 504a is located on both sides of the switch 400 and has slots 504b.

[0064] The connecting assembly 502 includes a moving plate 502a slidably disposed in the fixed plate 504a, a long rod 502b is fixedly disposed at the bottom of the moving plate 502a, a fixed rod 502c is sleeved on the outer side of the long rod 502b, the bottom end of the fixed rod 502c is fixedly connected to the floating plate 501, a cavity 502d is opened in the long rod 502b, a buckle assembly 503 is slidably disposed in the cavity 502d, and the fixed plate 504a can guide and limit the movement of the moving plate 502a. At the same time, since the moving plate 502a is slidably disposed in the fixed plate 504a, the floating plate 501 can be positioned above the water inlet 101d;

[0065] In normal state, the buckle assembly 503 is close to each other. When the water inflow of the inner ring 101a is greater than the drainage speed of the drain pipe 602, and the water line of the inner ring 101a exceeds the water inlet 101d, the floating plate 501 floats upward. At this time, due to the deadweight of the movable plate 502a, the fixed rod 502c does not move. After the floating plate 501 moves upward, the long rod 502b moves outside the fixed rod 502c, so that the two groups of buckle assemblies 503 slide away from each other and open. When the fixed rod 502c moves to the bottom of the movable plate 502a, the movable plate 502a is pushed upward until it conflicts with the switch 400. At this time, the buckle assembly 503 pops out and is connected with the card slot 5 04b is engaged, and then the position of the movable plate 502a is fixed. After the switch 400 is not resisted, the external pumping equipment is turned on, and the water in the inner ring part 101a is pumped out through the pumping pipe 300. After the water is pumped out, the floating plate 501 continues to drop. At this time, the position of the movable plate 502a is fixed until the floating plate 501 drops to a lower position, and the buckle assembly 503 is driven to disengage from the card slot 504b, and the movement is unlocked and moves downward. The switch 400 is reset, and the pumping equipment stops operating, so that the external equipment can automatically start drainage when there is a lot of water in the inner ring part 101a. At the same time, it can maintain a continuous pumping state until it automatically stops when there is less water in the inner ring part 101a.

[0066] Furthermore, a buckle assembly 503 is provided on the connecting assembly 502; after the connecting assembly 502 rises, the buckle assembly 503 can fix the position of the connecting assembly 502;

[0067] The buckle assembly 503 includes an L-shaped rod 503a disposed in the cavity 502d, the lateral portion of the L-shaped rod 503a extends out of the cavity 502d, guide posts 503b are fixedly provided at the bottom ends of both sides of the L-shaped rod 503a, a through slot 502f corresponding to the guide post 503b is formed on the fixed rod 502c, and guide slots 502e are formed on both sides of the long rod 502b, and the guide post 503b penetrates through the through slot 502f and extends into the guide slot 502e. The shape of the through slot 502f and the L-shaped rod 503a makes The guide column 503b can only move laterally. A short slot 503c is formed at the end of the transverse portion of the L-shaped rod 503a. An elastic member 503d is disposed in the short slot 503c. The elastic member 503d includes a spring 503d-1 disposed in the short slot 503c. A clamping block 503d-2 is fixedly disposed at the end of the spring 503d-1. The clamping slot 504b corresponds to the clamping block 503d-2. The short slot 503c can limit the clamping block 503d-2 to prevent the clamping block 503d-2 from detaching from the L-shaped rod 503a.

[0068] The guide groove 502e is provided with a short longitudinal section S1, an oblique section S2, and a long longitudinal section S3 from top to bottom. In the initial state, the guide column 503b is located in the short longitudinal section S1. At this time, the two sets of buckle components 503 are in a close state, the end of the L-shaped rod 503a is away from the inner wall of the fixed plate 504a, and the block 503d-2 is close to the inner wall of the fixed plate 504a. When the floating plate 501 moves upward, the long rod 502b moves outside the fixed rod 502c. The guide post 503b enters the long longitudinal section S3 through the oblique section S2. At this time, the L-shaped rod 503a guides and slides in the direction away from each other, so that the end of the L-shaped rod 503a approaches the inner wall of the fixed plate 504a, the block 503d-2 contacts the inner wall of the fixed plate 504a, the spring 503d-1 is squeezed, and then the floating plate 501 continues to move upward. When the long rod 502b moves to contact the bottom of the movable plate 502a, the movable plate 502a is moved by the floating plate 501. 01 pushes and continues to move upward until the moving plate 502a hits the switch 400. At this time, the block 503d-2 corresponds to the slot 504b, and the spring 503d-1 pushes the block 503d-2 to pop out and engage with the slot 504b, thereby fixing the position of the moving plate 502a. After the switch 400 is hit, the pumping equipment starts, and then the water in the inner ring 101a is discharged. When the floating plate 501 drops to a certain extent and the long rod 502b moves to the bottom of the fixed rod 502c, the guide column 503b enters the short longitudinal section S1 from the long longitudinal section S3 again. At this time, the buckle assembly 503 moves in a direction close to each other, thereby causing the two groups of blocks 503d-2 to disengage from the slot 504b, and the moving plate 502a drops and resets. After the switch 400 loses contact, the pumping equipment stops. Through the setting of the connecting assembly 502 and the buckle assembly 503, the pumping equipment will stop only after a certain amount of water is pumped out.

[0069] The rest of the structure is the same as that of Example 2.

[0070] By setting the resistance component, the water can be drained by the drain pipe 602 under normal conditions, and the pumping equipment can automatically start when there is more water in the inner ring 101a to prevent the floating island unit from being too heavy, thereby achieving the effect of reducing energy consumption. The setting of the buckle component 503 allows the pumping equipment to have a certain operating time to avoid frequent start and stop of the pumping equipment, which may cause damage to the equipment. At the same time, it can automatically stop after pumping out more water in the inner ring 101a.
