[0019] The technical solutions in the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0020] Specific implementation method one: as Figures 1-9As shown, the embodiment discloses a power collection device, which comprises a base 1, a support 2 hinged to one end of the base 1, a T-shaped sliding groove 11 arranged at the other end of the base 1, a spring 12 fixedly connected to the inner wall of the sliding groove 11, a sliding block 14 fixedly connected to the other end of the spring 12 and slidingly matched with the sliding groove 11, a support rod 21 hinged to the lower end of the support 2 and hinged to the sliding block 14 at the other end, a photovoltaic panel 3 fixedly connected to the support 2, a storage device 6 fixedly connected to the side of the support 2 facing the base 1, and a water tank 61 comprising a liquid collecting device 5 and a liquid discharge hole 64.

[0021] The aperture of the liquid inlet 65 is larger than that of the liquid discharge hole 64. After the rainwater enters the water tank 61, the amount of the rainwater can be gradually increased, and the rainwater can be timely discharged after the rain stops, so that the photovoltaic panel 3 can be moved to the original position as soon as possible.

[0022] The liquid discharge hole 64 is slidingly matched with a communication pipe 62 hinged to the upper end of the base 1, and the side of the communication pipe 62 is provided with a drain hole 63. The communication pipe 62 blocks part of the liquid discharge hole 64, so that the time for the rainwater to accumulate in the water tank 61 is shortened, and the photovoltaic panel 3 can be rotated as soon as possible to change the angle.

[0023] The outer diameter of the communication pipe 62 is smaller than the inner diameter of the liquid discharge hole 64, and after the support 2 is rotated towards the base 1, the drain hole 63 communicates the space inside the water tank 61 with the inside of the communication pipe 62. The drain hole 63 increases the drainage effect, so that the water inflow and outflow of the water tank 61 are balanced, and the inclination angle of the photovoltaic panel 3 is maintained.

[0024] The liquid collecting device 5 comprises a collecting groove 51, an arc-shaped hole 57 arranged on the bottom surface of the collecting groove 51, a pipeline 56 fixedly connected to the lower end of the collecting groove 51 and communicating the arc-shaped hole 57 with the liquid inlet 65, a ball 54 slidingly matched with the arc-shaped hole 57, shaft rods 58 fixedly connected to the two sides of the ball 54 and connected to the inner wall of the collecting groove 51 through bearings at the other ends, a through hole I 541 arranged at the top end of the ball 54, a through hole II 542 arranged at the bottom end of the ball 54 and communicating with the pipeline 56, an inlet pipe 53 fixedly connected to the upper end of the ball 54, and a float 52 fixedly connected to the outer side of the inlet pipe 53. The inlet pipe 53 is always in a vertical state under the action of the buoyancy of the float 52.

[0025] The bottom surface of the collecting groove 51 is also provided with a plurality of perforations 55.

[0026] The upper end of the support 2 is provided with a collector 4; the collector 4 comprises a fixed rod 42 fixedly connected to the support 2; the upper end of the fixed rod 42 is connected with an arc-shaped groove 41 through a spring hinge.

[0027] The hinge point of the arc-shaped groove 41 and the fixed rod 42 is located on the side of the lowest point of the arc-shaped groove 41 away from the photovoltaic panel 3.

[0028] The arc-shaped groove 41 is located below the perforations 55.

[0029] A use method of the power collection device, the use method comprising the following steps:

[0030] Step one: when it rains, the collecting groove 51 collects rainwater, part of the rainwater flows into the arc-shaped groove 41 through the perforations 55, the center of gravity of the arc-shaped groove 41 changes, and finally the arc-shaped groove 41 rotates around the spring hinge connected thereto and pours the rainwater in the arc-shaped groove 41 onto the upper end of the photovoltaic panel 3 to wash it;

[0031] Step two: another part of the rainwater accumulates in the collecting groove 51, and when the liquid level height exceeds the height of the liquid inlet pipe 53, the rainwater enters the water tank 61 through the liquid inlet pipe 53, the through hole I 541, the through hole II 542 and the pipeline 56, and when the water tank 61 accumulates rainwater, the weight increases, driving the support 2 and the photovoltaic panel 3 to rotate around the hinge towards the direction of the base 1, thereby increasing the projection area of the photovoltaic panel 3 on the horizontal plane, so that the rainwater can fall onto the photovoltaic panel 3 with a higher probability and wash the dust on the surface of the photovoltaic panel 3.

[0032] The working principle of the present application is that when the device is used in rainy days, the collecting groove 51 collects rainwater, part of the rainwater flows into the arc-shaped groove 41 through the perforations 55, the center of gravity of the arc-shaped groove 41 changes due to the eccentric position of the connecting position of the fixed rod 42 and the arc-shaped groove 41, and finally the arc-shaped groove 41 rotates around the spring hinge connected thereto and pours the rainwater in the arc-shaped groove 41 onto the upper end of the photovoltaic panel 3 to wash it; when the rain is small, the rainwater in the collecting groove 51 is continuously discharged due to the setting of the perforations 55, and the liquid level of the rainwater in the collecting groove 51 slowly rises or does not rise, so that the rainwater in the collecting groove 51 is collected, and when the rainwater is poured, the raindrops are gathered into a water flow, which is more convenient for washing the dust on the surface of the photovoltaic panel 3.

[0033] When the rain is heavy, the amount of water entering the collection tank 51 per unit time is greater than the drainage capacity of the perforations 55, causing the water level in the collection tank 51 to rise. When the height of the water level is higher than the inlet pipe 53, the rainwater in the collection tank 51 will flow into the water tank 61 through the inlet pipe 53, the through hole I 541, the through hole II 542, and the pipeline 56. Part of the rainwater entering the water tank 61 is discharged through the gap between the communication pipe 62 and the liquid outlet hole 64, and the other part accumulates in the water tank 61. As the volume of rainwater in the water tank 61 increases, the weight of the water tank 61 increases, thereby driving the support 2 and the photovoltaic panel 3 to rotate towards the base 1, reducing the angle between the support 2 and the base 1, and increasing the projection area of the photovoltaic panel 3 on the horizontal plane, thereby increasing the probability of rain falling on the photovoltaic panel 3. At the same time, the support rod 21 pushes the sliding block 14 to compress the spring 12. During the rotation of the support 2, the communication pipe 62 moves relative to the water tank 61, causing the drainage hole 63 on the side of the communication pipe 62 to communicate with the inner cavity of the water tank 61, thereby discharging the water in the water tank 61 until the water inflow and outflow of the water tank 61 are balanced. The total weight of the water tank 61 and the rainwater inside is relatively stable, and the support 2 and the base 1 maintain this angle until the rain stops.

[0034] After the rain stops, the water tank 61 no longer receives water, and the water in the water tank 61 is discharged through the drainage hole 63 and the gap between the communication pipe 62 and the liquid outlet hole 64. As the rainwater is discharged, the weight of the water tank 61 and the rainwater inside decreases, and the spring 12 pushes the support 2 to move away from the base 1. Until the photovoltaic panel 3 is moved to the original position, it can move to the original position as soon as possible after the rain, without waiting for the rainwater to evaporate, thereby ensuring that the photovoltaic panel 3 works as soon as possible and ensures the power generation efficiency.

[0035] When it rains, the position of the support 2 changes, and at the same time, the collection tank 51 also tilts, as shown in the state of Figure 3 Under the action of the float 52, the inlet pipe 53 always maintains a vertical state. Compared with the inlet pipe 53 tilting with the support 2, the highest point of the inlet pipe 53 in the vertical state is higher than that in the tilted state. Therefore, when the collection tank 51 is tilted, the inlet pipe 53 in the vertical state can store more rainwater in the collection tank 51 before flowing into the water tank 61 through the inlet pipe 53, to ensure that there is always rainwater in the collection tank 51 flowing into the arc-shaped groove 41 through the perforations 55 when the support 2 rotates by a small angle, and the collected rainwater washes the photovoltaic panel 3;

[0036] The support 2 and the photovoltaic panel 3 rotate by different angles depending on the size of the rain. When the rain is heavy, the rotation angle is large, which increases the projection area on the horizontal plane, effectively increasing the probability of rain falling on the photovoltaic panel 3 to wash away the dust. When the rain is light, the rotation angle is small or not rotated, and the photovoltaic panel 3 is washed by the rainwater falling on it and the rainwater accumulated in the arc-shaped groove 41, ensuring the dust cleaning effect.
