Description

Technical Field

[0001] The present invention relates to an electric power collection device and a method for using the same, belonging to the field of solar power generation. Background Art

[0002] Photovoltaic power generation is an environmentally friendly and renewable power generation technology. Photovoltaic power generation requires photovoltaic panels to be erected in areas with sufficient sunlight. Currently, common photovoltaic panels cannot be changed anymore without manual operation after adjusting the angle of the photovoltaic panels. However, photovoltaic panels are usually erected in the wild. If they are not cleaned for a long time, more dust will accumulate on the photovoltaic panels, affecting the power generation efficiency. Although rain will clean some of the dust on the photovoltaic panels, since the photovoltaic panels are usually inclined in the direction of the sun, the projected area of the photovoltaic panels in the horizontal direction is small. As a result, when it rains, the probability of raindrops falling on the photovoltaic panels decreases, resulting in poor cleaning effect of the dust on the surface of the photovoltaic panels by rainwater. Therefore, improvements are made to it. Summary of the Invention

[0003] The purpose of the present invention is to provide an electric power collection device and a method for using the same to solve the above problems in the background art.

[0004] To achieve the above purpose, the present invention adopts the following technical solutions:

[0005] An electric power collection device includes a base; one end of the base is hinged with a bracket, and the other end of the base is provided with a T-shaped chute. A spring is fixedly connected to the inner wall of the chute, and the other end of the spring is fixedly connected with a slider that is slidably matched with the chute; the lower end of the bracket is hinged with a support rod, and the other end of the support rod is hinged with the slider; a photovoltaic panel is fixedly connected to the bracket, and a storage device is fixedly connected to the side of the bracket facing the base; the storage device includes a water tank; a liquid collection device that is communicated with the inside of the water tank through a liquid inlet is fixedly connected to the upper middle part of the water tank, and a liquid discharge hole is provided at the lower part of the water tank.

[0006] A method for using an electric power collection device, the method comprising the following steps:

[0007] Step 1: When it rains, the collection trough collects rainwater, and part of the rainwater flows into the arc-shaped trough through the perforations, changing the center of gravity of the arc-shaped trough. Eventually, the arc-shaped trough rotates around the spring hinge connected to it and pours the rainwater in the arc-shaped trough onto the upper end of the photovoltaic panel to wash it.

[0008] Step 2: Another part of the rainwater accumulates in the collection trough. After the liquid level height exceeds the height of the liquid inlet pipe, it enters the water tank through the liquid inlet pipe, through hole Ⅰ, through hole Ⅱ, and the pipeline. After the water tank accumulates rainwater, the weight increases, driving the bracket and the photovoltaic panel to rotate around the hinge towards the direction of the base, thereby increasing the projected area of the photovoltaic panel on the horizontal plane, making it more likely for rainwater to drip onto the photovoltaic panel and wash the dust on its surface.

[0009] Compared with the prior art, the beneficial effects of the present invention are as follows: The present invention can not only change the angle between the photovoltaic panel and the base by accumulating rainwater, so that the photovoltaic panel can increase its projected area in the horizontal direction when it rains, thereby increasing the probability of raindrops falling on the photovoltaic panel and enhancing the dust cleaning effect. Moreover, after the rain stops, the rainwater can be drained without waiting for evaporation, enabling the photovoltaic panel to return to the preset angle in a short time and ensuring the power generation efficiency.

[0019] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0020] DETAILED DESCRIPTION OF THE INVENTION I: As Figures 1-9As shown in the figure, this embodiment describes a power collection device, including a base 1; one end of the base 1 is hinged with a bracket 2, and the other end of the base 1 is provided with a T-shaped chute 11. A spring 12 is fixedly connected to the inner wall of the chute 11, and the other end of the spring 12 is fixedly connected to a slider 14 that is slidably matched with the chute 11; the lower end of the bracket 2 is hinged with a support rod 21, and the other end of the support rod 21 is hinged with the slider 14; a photovoltaic panel 3 is fixedly connected to the bracket 2, and a storage device 6 is fixedly connected to the side of the bracket 2 facing the base 1; the storage device 6 includes a water tank 61; a liquid collection device 5 that is connected to the inside of the water tank 61 through a liquid inlet 65 is fixedly connected to the upper middle part of the water tank 61, and a liquid discharge hole 64 is provided at the lower part of the water tank 61. By collecting rainwater, the weight of the water tank 61 is increased to drive the bracket 2 and the photovoltaic panel 3 to rotate, thereby increasing the projected area of the photovoltaic panel 3 on the horizontal plane, increasing the probability of rainwater dripping on the photovoltaic panel 3, and enhancing the dust cleaning effect. A baffle 13 covering the upper end of the chute 11 is fixedly connected to the upper end of the slider 14.

[0021] The aperture of the liquid inlet 65 is larger than the aperture of the liquid discharge hole 64. So that the rainwater can gradually increase after entering the water tank 61, and at the same time, after the rain stops, the rainwater can be discharged in time, so that the photovoltaic panel 3 can move to the original position to work as soon as possible.

[0022] The liquid discharge hole 64 is slidably matched with a communicating pipe 62, and the communicating pipe 62 is hinged to the upper end of the base 1; a drain hole 63 is provided on the side of the communicating pipe 62. By blocking part of the liquid discharge hole 64 with the communicating pipe 62, the time for rainwater to accumulate in the water tank 61 is shortened, so that the photovoltaic panel 3 can rotate as soon as possible and change its angle.

[0023] The outer diameter of the communicating pipe 62 is smaller than the inner diameter of the liquid discharge hole 64, and after the bracket 2 rotates towards the direction where the base 1 is located, the drain hole 63 connects the internal space of the water tank 61 with the inside of the communicating pipe 62. By the drain hole 63, the drainage effect is increased, the water inflow and outflow positions of the water tank 61 are balanced, and the inclination angle of the photovoltaic panel 3 is maintained.

[0024] The liquid collection device 5 includes a collection tank 51; an arc-shaped hole 57 is provided on the bottom surface of the collection tank 51; a pipe 56 that connects the arc-shaped hole 57 and the liquid inlet 65 is fixedly connected to the lower end of the collection tank 51; a sphere 54 that is slidably matched with the arc-shaped groove 57 is provided in the arc-shaped groove 57, and shaft rods 58 are fixedly connected to both sides of the sphere 54. The other ends of the shaft rods 58 are connected to the inner wall of the collection tank 51 through bearings; a through hole Ⅰ541 is provided at the top end of the sphere 54, and a through hole Ⅱ542 that is communicated with the pipe 56 is provided at the bottom end of the sphere 54; a liquid inlet pipe 53 is fixedly connected to the upper end of the sphere 54; a floating block 52 is fixedly connected to the outside of the liquid inlet pipe 53. So that the liquid inlet pipe 53 is always in a vertical state under the buoyancy of the floating block 52.

[0025] A plurality of through holes 55 are further provided on the bottom surface of the collection tank 51.

[0026] A collector 4 is provided at the upper end of the bracket 2; the collector 4 includes a fixed rod 42 fixedly connected to the bracket 2; the upper end of the fixed rod 42 is connected by a spring hinge to an arc-shaped groove 41.

[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 through holes 55.

[0029] A method for using a power collection device, the method comprising the following steps:

[0030] Step 1: When it rains, the collection tank 51 collects rainwater, and part of the rainwater flows into the arc-shaped groove 41 through the through holes 55, causing the center of gravity of the arc-shaped groove 41 to change. Eventually, the arc-shaped groove 41 rotates around the spring hinge connected thereto, and the rainwater in the arc-shaped groove 41 is poured onto the upper end of the photovoltaic panel 3 to wash it.

[0031] Step 2: Another part of the rainwater accumulates in the collection tank 51. After the liquid level height exceeds the height of the liquid inlet pipe 53, it 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. After the water tank 61 accumulates rainwater, its weight increases, driving the bracket 2 and the photovoltaic panel 3 to rotate around the hinge in the direction of the base 1, thereby increasing the projected area of the photovoltaic panel 3 on the horizontal plane, making it more likely for rainwater to drip onto the photovoltaic panel 3 and wash the dust on its surface.

[0032] The working principle of the present invention is: when using this device on a rainy day, when it rains, the collection tank 51 collects rainwater, and part of the rainwater flows into the arc-shaped groove 41 through the through holes 55. Since the connection position between the fixed rod 42 and the arc-shaped groove 41 is located at an eccentric position of the arc-shaped groove 41, the rainwater causes the center of gravity of the arc-shaped groove 41 to change. Eventually, the arc-shaped groove 41 rotates around the spring hinge connected thereto, and the rainwater in the arc-shaped groove 41 is poured onto the upper end of the photovoltaic panel 3 to wash it. When the rain is light, due to the setting of the through holes 55, the rainwater in the collection tank 51 is continuously discharged, and the rainwater liquid level in the collection tank 51 rises slowly or does not rise. Therefore, after the collection tank 51 collects rainwater, the rainwater converges in the arc-shaped groove 41. When it pours rainwater, the raindrops converge 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 water inflow rate per unit time in the collection tank 51 is greater than the drainage rate of the perforations 55, causing the rainwater level in the collection tank 51 to rise. After the rainwater level height is higher than the liquid inlet pipe 53, the rainwater in the collection tank 51 will enter the water tank 61 along the liquid inlet pipe 53, the through hole Ⅰ541, the through hole Ⅱ542 and the pipeline 56. Part of the rainwater entering the water tank 61 is discharged through the gap between the communicating pipe 62 and the liquid discharge 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 bracket 2 and the photovoltaic panel 3 to rotate in the direction of the base 1, reducing the angle between the bracket 2 and the base 1, and then increasing the projected area of the photovoltaic panel 3 on the horizontal plane, so as to increase the probability of rainwater falling on the photovoltaic panel 3. At the same time, the support rod 21 pushes the slider 14 to compress the spring 12. During the rotation of the bracket 2, the communicating pipe 62 moves relative to the water tank 61, making the drainage hole 63 on the side of the communicating pipe 62 communicate with the inner cavity of the water tank 61, and then discharging the water in the water tank 61. Until the water inflow and outflow in the water tank 61 are balanced, the total weight of the water tank 61 and the rainwater inside it is relatively stable, and the bracket 2 and the base 1 maintain this angle until the rain stops;

[0034] After the rain stops, the water tank 61 stops receiving water, and the water in the water tank 61 is discharged through the drainage hole 63 and the gap between the communicating pipe 62 and the liquid discharge hole 64. As the rainwater is discharged, the weight of the water tank 61 and the rainwater inside it decreases. The elastic force of the spring 12 pushes the bracket 2 to move away from the base 1 until the photovoltaic panel 3 is moved back to its original position, enabling it to move back 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 starts working as soon as possible and guaranteeing the power generation efficiency;

[0035] When it is raining, while the position of the bracket 2 changes, since the collection tank 51 also tilts accordingly, as Figure 3 shown in the figure, and the liquid level always remains horizontal. Under the action of the floating block 52, the liquid inlet pipe 53 will always remain vertical. Compared with the liquid inlet pipe 53 tilting with the bracket 2, the highest point of its vertical state is higher than the highest point of its tilted state. Therefore, when the collection tank 51 tilts, the vertical state of the liquid inlet pipe 53 can store more rainwater in the collection tank 51 and then flow into the water tank 61 through the liquid inlet pipe 53, so as to ensure that when the bracket 2 rotates by a small angle, there is always rainwater in the collection tank 51 flowing into the arc-shaped groove 41 through the perforations 55 to collect rainwater and wash the photovoltaic panel 3;

[0036] The bracket 2 and the photovoltaic panel 3 rotate by different angles according to the intensity of the rain. When the rain is heavy, the rotation angle is large, increasing the projected area on the horizontal plane, which can effectively increase the probability of raindrops falling on its upper end to wash away dust; when the rain is light, the rotation angle is small or does not rotate, and the photovoltaic panel 3 is washed by the rainwater dripping on it and the rainwater accumulated in the arc-shaped groove 41 to ensure the dust cleaning effect.
