Description

Technical Field

[0001] This application relates to the technical field of photovoltaic panel power generation, and particularly to a power generation device with a photovoltaic panel cleaning function. Background Art

[0002] Photovoltaic panels are gradually being widely used due to the demand for environmental protection and sustainable energy. However, most photovoltaic panels are installed in outdoor environments. As the photovoltaic panels operate for a long time, a large amount of pollutants such as dust and bird excrement will accumulate on their surfaces, which will seriously affect the power generation efficiency and service life of the photovoltaic panels. Therefore, it is necessary to clean the photovoltaic panels regularly.

[0003] In the related art, Chinese Patent with the application number CN202322498092.8 proposed a self-cleaning photovoltaic panel structure, which includes two groups of protective boxes and a mounting plate connected between the two groups of protective boxes. A photovoltaic panel is installed inside the mounting plate. There is a mounting rod between the protective boxes, and a cleaning member for cleaning the surface of the photovoltaic panel is installed at the bottom of the mounting rod. Guide blocks are connected to both ends of the mounting rod, and guide grooves for the guide blocks to slide are provided on one side of the two groups of protective boxes close to each other. A driving member for driving the guide blocks to reciprocate in the guide grooves is installed on the protective boxes. The cleaning member includes a mounting rod, a cleaning rod is provided at the bottom of the mounting rod, and a cleaning brush is connected to the bottom of the cleaning rod.

[0004] In view of the above related art, when the driving member drives the guide block to drive the cleaning rod to slide back and forth on the photovoltaic panel, the cleaning brush can scrape and clean the pollutants on the photovoltaic panel. However, for some pollutants with a certain viscosity, it is difficult to quickly scrape the pollutants from the photovoltaic panel only by the cleaning brush, resulting in low cleaning efficiency of the photovoltaic panel. Summary of the Utility Model

[0005] In order to improve the problem of low cleaning efficiency of photovoltaic panels, this application provides a power generation device with a photovoltaic panel cleaning function.

[0006] The power generation device with a photovoltaic panel cleaning function provided by this application adopts the following technical solutions:

[0007] A power generation device with a photovoltaic panel cleaning function includes a plurality of frames and photovoltaic panels installed on the frames. It is characterized in that a cleaning plate is slidably arranged on the frame. The cleaning plate is located above the photovoltaic panel. A scraping member that slidably contacts the photovoltaic panel is arranged at the bottom of the cleaning plate. A flushing assembly for obliquely flushing the photovoltaic panel is also arranged on the cleaning plate.

[0008] Furthermore, the cleaning plate is hollow, and the flushing assembly includes a plurality of spray heads installed at the bottom of the cleaning plate and communicating with the hollow cavity of the cleaning plate, and a connector installed on the cleaning plate and communicating with the hollow cavity of the cleaning plate. The connector is communicated with a water source. The spray heads spray in a direction away from the scraping member, and the spraying direction of the spray heads is set at an acute angle to the photovoltaic panel.

[0009] Furthermore, the spray heads are embedded on the surface of the bottom of the cleaning plate.

[0010] Furthermore, the bottom of the cleaning plate is set as an inclined surface, and the vertical distance from the inclined surface to the photovoltaic panel gradually increases in the direction away from the scraping member. The spray heads are vertically installed on the inclined surface.

[0011] Furthermore, a sliding groove is provided on one side of the frame body. The length direction of the sliding groove is the same as the length direction of the photovoltaic panel and perpendicular to the length direction of the cleaning plate. A slider is slidably installed in the sliding groove. The top of the slider is fixedly connected to the cleaning plate. A driving member for driving the slider to slide back and forth is also provided in the sliding groove.

[0012] Furthermore, a fastener for stably connecting the two adjacent frame bodies is provided between the two adjacent frame bodies.

[0013] Furthermore, notches are provided at the corners of the frame body. The fastener includes a convex block inserted and adapted to the two adjacent notches and a locking member for locking the convex block in the notch.

[0014] Furthermore, the frame body is hollow.

[0015] In summary, the present application includes at least one of the following beneficial technical effects:

[0016] 1. The photovoltaic panel is obliquely flushed by the flushing assembly, so that pollutants are not easily adhered to the photovoltaic panel. Furthermore, when the cleaning plate slides on the photovoltaic panel, the scraping member on the cleaning plate can quickly scrape the pollutants from the photovoltaic panel, improving the cleaning efficiency of the pollutants on the photovoltaic panel.

[0017] 2. The bottom of the cleaning plate is provided with an inclined surface, and the spray heads are vertically embedded on the inclined surface, so that when the cleaning plate slides, the spray heads will not scratch the photovoltaic panel. At the same time, the spray heads spray high-pressure water in a direction away from the scraping member, avoiding the accumulation of pollutants on the photovoltaic panel at the scraping member, so that the scraping member can more efficiently complete the cleaning work of the photovoltaic panel.

Detailed implementation manners

[0026] To make the objectives, technical solutions, and advantages of the present invention clearer, the following will clearly and completely describe the technical solutions in the present invention in conjunction with the drawings in the present invention. Obviously, the described embodiments are some, but not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the scope of protection of the present invention.

[0027] The embodiment discloses a power generation device with a photovoltaic panel cleaning function. Refer to Figure 1 and Figure 2, A power generation device with a photovoltaic panel cleaning function includes several frames 1 and photovoltaic panels 2 installed on the frames 1. The frames 1 are hollowly arranged, enabling the photovoltaic panels 2 to dissipate heat better during the process of converting light energy into electrical energy, thus ensuring their power generation efficiency. Since contaminants are likely to accumulate on the upper surface of the photovoltaic panels 2, affecting their power generation efficiency, a cleaning plate 3 for cleaning the contaminants on its surface is provided above the photovoltaic panels 2. The length direction of the cleaning plate 3 is the same as the width direction of the photovoltaic panels 2, and the cleaning plate 3 is slidably connected to the frames 1 along the length direction of the photovoltaic panels 2.

[0028] Considering the cleaning efficiency and effect of the contaminants on the surface of the photovoltaic panels 2, referring to Figure 1 and Figure 3 , a scraping member 4 for slidably scraping the contaminants on the surface of the photovoltaic panels 2 is installed at the bottom of the cleaning plate 3. The length direction of the scraping member 4 is the same as the length direction of the cleaning plate 3 and is located on one side of the cleaning plate 3. The scraping member 4 can be a brush plate, a sponge brush, or a rubber brush. To avoid scratching the surface of the photovoltaic panels 2 while ensuring the cleaning effect on the photovoltaic panels 2, in the embodiment of the present application, the scraping member 4 is set as a rubber brush, and the rubber brush elastically abuts against the surface of the photovoltaic panels 2. As the cleaning plate 3 moves above the photovoltaic panels 2, the rubber brush at the bottom of the cleaning plate 3 can slidably scrape the contaminants on the surface of the photovoltaic panels 2.

[0029] Since some contaminants have a certain viscosity, under the slidable scraping of the rubber brush, they will still adhere to the surface of the photovoltaic panels 2, making it difficult to be scraped and cleaned. For this reason, referring to Figure 1 and Figure 3 , a flushing assembly for obliquely flushing the photovoltaic panels 2 is further provided on the cleaning plate 3. The cleaning plate 3 is hollowly arranged. The flushing assembly includes a connector 6 provided on the cleaning plate 3 and communicated with an external water source and several spray heads 5 provided on the cleaning plate 3. Both the spray heads 5 and the connector 6 are communicated with the hollow cavity of the cleaning plate 3. By connecting the water source to the connector 6, the cleaning plate 3 is filled with water. At this time, the water in the cleaning plate 3 can be sprayed towards the photovoltaic panels 2 through several spray heads 5, thereby flushing the contaminants adhering to the photovoltaic panels 2, making it difficult for the contaminants to adhere to the photovoltaic panels 2. In order to improve the flushing efficiency of the photovoltaic panels 2, in the embodiment of the present application, multiple spray heads 5 are provided. The multiple spray heads 5 are all located on one side of the scraping member 4 and are arranged at intervals along the length direction of the cleaning plate 3. At the same time, the spraying direction of the spray heads 5 is sprayed towards the direction away from the scraping member 4, and the spraying direction of the spray heads 5 is set at an acute angle with the photovoltaic panels 2; so that the water sprayed out by the spray heads 5 can obliquely flush the contaminants adhering to the surface of the photovoltaic panels 2, prompting the contaminants to be quickly flushed to the direction away from the scraping member 4, avoiding the contaminants from concentrating and accumulating on one side of the scraping member 4 and affecting the slidable scraping efficiency of the scraping member 4 on the contaminants on the photovoltaic panels 2.

[0030] Considering that the cleaning plate 3 drives a plurality of spray heads 5 to slide and clean on the photovoltaic panel 2, in order to prevent the pollutants on the surface of the photovoltaic panel 2 from clogging the spray heads 5 or the spray heads 5 scratching the surface of the photovoltaic panel 2 due to the small distance between the spray heads 5 and the photovoltaic panel 2, with reference to Figure 3 the spray heads 5 are embedded on the bottom surface of the cleaning plate 3, so that the spraying ends of the spray heads 5 do not protrude from the bottom surface of the cleaning plate 3. In order to enable the spray heads 5 to be conveniently and stably installed on the cleaning plate 3 and the spraying direction thereof to be set at an acute angle with the photovoltaic panel 2, in the embodiment of the present application, the bottom of the cleaning plate 3 is provided with an inclined surface 11, and the vertical distance from the inclined surface 11 to the photovoltaic panel 2 gradually increases in the direction away from the scraping member 4, and the spray heads 5 are vertically embedded on the inclined surface 11. In other embodiments, a stepped groove is provided at the bottom of the cleaning plate 3, the bottom wall of the stepped groove is higher than the installation surface of the scraping member 4, and the spray heads 5 are inclinedly installed on the bottom wall of the stepped groove, so that there is a certain space between the spraying ends of the spray heads 5 and the photovoltaic panel 2, and the spraying ends of the spray heads 5 and the photovoltaic panel 2 are set at an acute angle.

[0031] In order to enable the cleaning plate 3 to slide and scrape smoothly on the photovoltaic panel 2, with reference to Figure 1 、 Figure 2 、 Figure 3 and Figure 4 a chute 8 is provided on one side of the frame body 1, the length direction of the chute 8 is the same as the length direction of the photovoltaic panel 2, a slider 10 is slidably installed in the chute 8, the top of the slider 10 is fixedly connected to the cleaning plate 3, and a driving member 9 for driving the slider 10 to slide back and forth is further provided in the chute 8. The driving member 9 drives the slider 10 to reciprocate in the chute 8, thereby driving the cleaning plate 3 to slide and scrape on the upper side of the photovoltaic panel 2. Considering the power generation efficiency, multiple photovoltaic panels 2 are often assembled one by one in sequence. In order to save the investment and use of the driving member 9 and the slider 10, two photovoltaic panels 2 arranged horizontally along the width direction of the photovoltaic panel 2 can share one driving member 9 and one slider 10; that is, the chutes 8 on one side of the two photovoltaic panels 2 are arranged close to each other, and the two chutes 8 are communicated with each other, the slider 10 is slidably installed in the two chutes 8, the driving member 9 is also located in the two chutes 8, and the slider 10 is connected to the middle of the cleaning plate 3, so that the driving member 9 can drive the slider 10 to slide between the two photovoltaic panels 2, and the slider 10 drives the cleaning plate 3 to clean the surfaces of the adjacent two photovoltaic panels 2 at the same time.

[0032] Regarding the setting of the driving member 9, with reference to Figure 2 、 Figure 3 、 Figure 4 and Figure 5, in the embodiment of the present application, the driving member 9 includes a lead screw 92 rotatably installed in the chute 8 and a motor 91 for driving the lead screw 92 to rotate. The length direction of the lead screw 92 is consistent with the length direction of the chute 8. Both ends of the lead screw 92 are rotatably installed in the chute 8 through supports. The motor 91 is stably installed on one side of the frame body 1 through the frame 13, and the output end of the motor 91 is fixedly connected to one end of the lead screw 92. The slider 10 is threadedly sleeved on the lead screw 92, and the side wall of the slider 10 is attached to the side wall of the chute 8. So that under the drive of the motor 91, the lead screw 92 can stably drive the slider 10 to slide in the chute 8, so that the cleaning plate 3 can effectively clean the surface of the photovoltaic panel 2. In other embodiments, the driving member 9 can be an electric push rod or a small hydraulic rod, etc.

[0033] Considering the convenience and stability of assembling multiple photovoltaic panels 2, referring to Figure 1 , Figure 2 and Figure 6 , a fastener 7 for stably connecting the two adjacent frame bodies 1 is provided between the two adjacent frame bodies 1. In a feasible embodiment, the fastener 7 is set as a connecting piece, and both ends of the connecting piece are respectively welded to the two adjacent frame bodies 1, so that the two adjacent frame bodies 1 can be stably assembled and connected under the connection action of the connecting piece. In the embodiment of the present application, the fastener 7 includes a convex block 71 and a locking member 72. Both ends of the convex block 71 extend with ear plates 14, and the convex block 71 protrudes from the ear plates 14. Notches 12 are formed at the corners of the frame body 1. When the two adjacent frame bodies 1 are aligned and assembled, the two notches 12 on the frame body 1 are aligned and communicated. At this time, the convex block 71 is inserted into the two notches 12, and the ear plates 14 on both sides are abutted against the side wall of the frame body 1. At this time, the convex block 71 is attached to the inner walls of the two notches 12; and the locking member 72 is two locking screws respectively passing through the two ear plates 14 and threadedly connected to the two frame bodies 1. Under the locking action of the locking screws, the ear plates 14 and the convex block 71, the two frame bodies 1 can be stably assembled and connected together.

[0034] The implementation principle of a power generation device with a photovoltaic panel cleaning function in the embodiment of the present application is as follows: First, a plurality of photovoltaic panels 2 are assembled together one by one through the fastener 7, then the driving member 9 and the slider 10 are installed in the chute 8 on one side of the frame body 1, and then the cleaning plate 3 is fixed on the slider 10. When it is necessary to clean the photovoltaic panel 2, the water source can be connected to the connector 6 on the cleaning plate 3 through a flexible water pipe, and at the same time, the driving member 9 is started. At this time, the spray head 5 can obliquely wash the photovoltaic panel 2, so that the pollutants on the photovoltaic panel 2 are not easily adhered to the surface of the photovoltaic panel 2. In addition, the scraping member 4 at the bottom of the cleaning plate 3 can scrape off the pollutants after washing, so as to efficiently complete the cleaning of the pollutants on the surface of the photovoltaic panel 2 and ensure the power generation efficiency of the photovoltaic panel 2.
