Description

Technical Field

[0001] The present application relates to the field of photovoltaic power generation technology, and in particular to a rooftop photovoltaic power generation panel assembly. Background Art

[0002] Photovoltaic power generation refers to the technology of converting light energy into electrical energy using photovoltaic panels (assemblies). Nowadays, rooftop photovoltaic panel assemblies are often used to receive and convert sunlight that shines on the roof, thereby achieving photovoltaic power generation.

[0003] Some existing rooftop photovoltaic panel assemblies are mainly composed of a mounting base, a bracket, a photovoltaic panel and a cleaning mechanism. When in use, the photovoltaic panel is installed on the roof through the mounting base and the bracket, so that it can receive sunlight shining on the roof and convert it into electrical energy. In addition, the cleaning mechanism is used to regularly spray pressurized water flow on the surface of the photovoltaic panel that receives sunlight, so that the dust accumulated on the surface of the photovoltaic panel is washed away, thereby reducing the impact of dust on the photovoltaic panel's reception of sunlight.

[0004] However, in the above process, when the cleaning mechanism cleans the photovoltaic panels, the water and dust flowing on the surface of the photovoltaic panels will affect the power generation efficiency of the photovoltaic panels, and when the water on the surface of the photovoltaic panels has not completely evaporated, the remaining water droplets will easily attract dust to stick, thereby further affecting the power generation efficiency of the photovoltaic panels. Summary of the invention

[0005] The present application proposes a rooftop photovoltaic panel assembly, which has the advantage of shortening the time that flowing water and dust contact the photovoltaic panel, and is used to solve the problem that flowing water, dust and residual water droplets affect the power generation efficiency of the photovoltaic panel.

[0006] To achieve the above-mentioned purpose, the present application adopts the following technical solution: a rooftop photovoltaic power generation panel assembly, comprising: a mounting seat, a photovoltaic power generation panel is arranged above the mounting seat, a No. 1 bracket is fixedly installed on both the front and rear sides of the lower side of the photovoltaic power generation panel, the lower end of the No. 1 bracket is fixedly connected to the mounting seat, and the right side of the photovoltaic power generation panel is tilted downward so that the upper surface of the photovoltaic power generation panel receives sunlight; The photovoltaic power generation panel is provided with a shell on both sides, a rotating wheel is rotatably installed inside the shell, a covering member is sleeved on the outer side of the photovoltaic power generation panel, and the covering member is partially a transparent plastic film. The left and right sides of the covering member are respectively sleeved on the outer sides of the corresponding rotating wheels, and the shells on both sides are fixedly installed on the mounting seat through a No. 2 bracket, a motor is fixedly installed on the No. 2 bracket, and the rotating shaft of the motor is fixedly connected to the corresponding rotating wheel. A nozzle is provided at a position between the covering member and the mounting seat, the upper output end of the nozzle faces the covering member, and the lower input end of the nozzle is connected to the water pump.

[0007] Furthermore, a storage shell is fixedly installed parallel to the lower side of the photovoltaic panel, the storage shell is opened on one side facing the outer shell, the covering member at the lower side of the photovoltaic panel passes through the storage shell, and the nozzle is fixedly installed on the left side of the storage shell.

[0008] Furthermore, the storage shell is divided into side shells on the left and right sides and an intermediate shell in the middle position. The side shells on both sides are fixedly connected to the photovoltaic panels, the intermediate shell is in sliding contact with the side shells, and a telescopic rod is fixedly installed on the upper side of the mounting seat, and the output rod of the telescopic rod is fixedly connected to the intermediate shell.

[0009] Furthermore, the cover is divided into transparent parts located on the upper and lower sides of the photovoltaic power generation panel and elastic parts located on the left and right sides of the photovoltaic power generation panel, and the lower transparent part passes through the side shell and the middle shell.

[0010] Furthermore, bumps are fixedly mounted at equal intervals on the circumferential side of the rotating wheel, the surface of the bumps is a rough surface, and the elastic part is sleeved on the outer side of the rotating wheel and the bumps.

[0011] Furthermore, a pressing plate is arranged inside the side shell and above the lower transparent portion, and a side of the pressing plate facing the middle shell is fixedly connected to the middle shell.

[0012] Furthermore, a baffle is provided inside the left side shell, and there is a gap between the upper side of the baffle and the lower transparent part, so as to block the water flow sprayed from the nozzle.

[0013] Furthermore, the baffle is slidably arranged inside the side shell, the lower side of the baffle passes through the side shell, a fixing plate is fixedly installed on the lower side of the baffle, a spring is fixedly installed on the side of the fixing plate facing the side shell, and the upper end of the spring is fixedly connected to the side shell.

[0014] This application has the following beneficial effects: The present application provides a rooftop photovoltaic panel assembly, which, through the arrangement of a cover, a wheel and a nozzle, utilizes the timed rotation of the wheel to drive the cover on the upper and lower sides of the photovoltaic panel to exchange positions timedly, and then utilizes the nozzle to clean the cover on the lower side of the photovoltaic panel. Through the above-mentioned action, the flowing water and dust are less likely to affect the power generation efficiency of the photovoltaic panel.

[0015] Through the arrangement of the covering member, the rotating wheel, the nozzle and the storage shell, when the nozzle cleans the covering member at the lower side of the photovoltaic panel, at this time, the side of the covering member at the lower side that receives sunlight faces downward, and the covering member at the lower side is inside the storage shell, so that the flowing water and dust can not only slide downward along the inner wall of the storage shell, but also directly leave the covering member under their own gravity, so that the retention time of water droplets on the covering member is shortened, thereby reducing the influence of subsequent residual water droplets on the power generation efficiency of the photovoltaic panel.

[0016] Through the arrangement of the nozzle, the storage shell and the pressure plate, during the process of the nozzle cleaning the covering member at the lower position, the pressure plate drives the covering member at the lower position to intermittently move away from the photovoltaic panel, thereby making the covering member at the lower position intermittently approach the water flow moving downward in the storage shell, causing the pressure of the water flow when contacting the covering member to continuously change, making it easier for dust adhered to the surface of the covering member to fall off, thereby reducing the impact on the power generation efficiency of the photovoltaic panel.

DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0021] Example 1: Please refer to Figure 1-Figure 3 A roof photovoltaic power generation panel assembly comprises a mounting seat 1, a photovoltaic power generation panel 2 is arranged above the mounting seat 1, a No. 1 bracket 3 is fixedly installed on both the front and rear sides of the lower side of the photovoltaic power generation panel 2, the lower end of the No. 1 bracket 3 is fixedly connected to the mounting seat 1, the right side of the photovoltaic power generation panel 2 is tilted downward, so that the upper surface of the photovoltaic power generation panel 2 receives sunlight, a shell 4 is arranged on the left and right sides of the photovoltaic power generation panel 2, a rotating wheel 5 is rotatably installed inside the shell 4, a covering member 6 is sleeved on the outer side of the photovoltaic power generation panel 2, the covering member 6 is partially a transparent plastic film, and the left and right sides of the covering member 6 are respectively sleeved on the outer side of the corresponding rotating wheel 5, the shells 4 on both sides are fixedly installed on the mounting seat 1 through a No. 2 bracket 7, a motor 8 is fixedly installed on the No. 2 bracket 7, the rotating shaft of the motor 8 passes through the No. 2 bracket 7 and the shell 4, and is fixedly connected to the corresponding rotating wheel 5, a nozzle 9 is arranged at a position between the covering member 6 and the mounting seat 1, the upper output end of the nozzle 9 faces the covering member 6, and the lower input end of the nozzle 9 is connected to a water pump (existing technology, not shown in the figure).

[0022] When in use, the photovoltaic panel 2 is installed on the roof through the mounting base 1 and the No. 1 bracket 3, so that it receives sunlight shining on the roof and converts it into electrical energy. After that, the motor 8 is operated regularly and drives the rotating wheel 5 to rotate regularly, so that the covering members 6 on the upper and lower sides of the photovoltaic panel 2 exchange positions regularly. After that, the nozzle 9 is used to clean the covering member 6 at the lower side of the photovoltaic panel 2. Through the above actions, the flowing water and dust are not easy to affect the power generation efficiency of the photovoltaic panel 2. At the same time, because the side of the covering member 6 at the lower side that receives sunlight faces downward, the flowing water and dust can be directly separated from the covering member 6 by their own gravity, so that the retention time of water droplets on the covering member 6 is shortened, thereby reducing the influence of subsequent residual water droplets on the power generation efficiency of the photovoltaic panel 2.

[0023] Example 2: Please refer to Figure 1-Figure 7 This embodiment is a further improvement of the first embodiment, and the improvement lies in that a storage shell 10 is fixedly installed parallel to the lower side of the photovoltaic panel 2, the side of the storage shell 10 facing the outer shell 4 is opened, the cover member 6 at the lower side of the photovoltaic panel 2 passes through the storage shell 10, and the nozzle 9 is fixedly installed at the left side of the storage shell 10.

[0024] When the nozzle 9 cleans the covering member 6 at the lower side of the photovoltaic panel 2, at this time, the side of the covering member 6 at the lower side that receives sunlight faces downward, and the covering member 6 at the lower side is inside the storage shell 10, so that the flowing water and dust can not only slide downward along the inner wall of the storage shell 10, but also directly separate from the covering member 6 under their own gravity, so that the retention time of water droplets on the covering member 6 is shortened, thereby reducing the influence of subsequent residual water droplets on the power generation efficiency of the photovoltaic panel 2. At the same time, the storage shell 10 prevents dust from contacting the covering member 6 at the lower side to a certain extent, thereby further improving the cleanliness of the covering member 6.

[0025] Example 3: Please refer to Figure 1-Figure 8 This embodiment is a further improvement of the second embodiment, and the improvement lies in that: the storage shell 10 is divided into side shells 100 on the left and right sides and an intermediate shell 101 in the middle position, the side shells 100 on both sides are fixedly connected with the photovoltaic power generation panel 2, the intermediate shell 101 forms a sliding contact with the side shell 100, and a telescopic rod 11 (such as a combination of an electric telescopic cylinder and an output rod in the prior art) is fixedly installed on the upper side of the mounting seat 1, and the output rod of the telescopic rod 11 is fixedly connected with the intermediate shell 101, and the covering member 6 is divided into a transparent part 60 located on the upper and lower sides of the photovoltaic power generation panel 2 and an elastic part 61 located on the left and right sides of the photovoltaic power generation panel 2, and the lower transparent part 60 passes through the side shell 100 and the intermediate shell 101.

[0026] When the nozzle 9 cleans the transparent portion 60 at the lower position, the telescopic rod 11 reciprocates and retracts at regular intervals, so that the intermediate shell 101 drives the transparent portion 60 at the lower position to intermittently move away from the photovoltaic panel 2 (at this time, the transparent portion 60 at the lower side will intermittently stretch the elastic portions 61 on both sides), thereby making the transparent portion 60 at the lower position intermittently approach the water flow moving downward in the storage shell 10, causing the pressure of the water flow when contacting the transparent portion 60 to change continuously, making it easier for dust adhered to the surface of the transparent portion 60 to fall off, thereby reducing the impact on the power generation efficiency of the photovoltaic panel 2 (when the intermediate shell 101 moves relative to the side shell 100, the lower side of the intermediate shell 101 is always in a sliding contact state with the lower side of the side shell 100, so that the water flow sliding downward in the storage shell 10 is not easy to be discharged from the gap between the side shell 100 and the intermediate shell 101).

[0027] See also Figure 2 and Figure 3 The circumferential side of the rotating wheel 5 is fixedly provided with convex blocks at equal intervals, the surface of the convex blocks is a rough surface, and the elastic part 61 is sleeved on the outer side of the rotating wheel 5 and the convex blocks.

[0028] Through the above arrangement, the friction between the rotating wheel 5 and the cover 6 is increased, so that the cover 6 is not easy to slide relative to the wheel 5, thereby making the device run stably.

[0029] A pressing plate 12 is disposed inside the side shell 100 and above the lower transparent portion 60 . The pressing plate 12 is fixedly connected to the middle shell 101 on one side thereof facing the middle shell 101 .

[0030] During the reciprocating movement of the intermediate shell 101 , the pressure plate 12 is driven to move synchronously, thereby causing the lower transparent portion 60 to intermittently approach the water flow moving downward in the storage shell 10 , thereby further reducing the impact on the power generation efficiency of the photovoltaic panel 2 .

[0031] Example 4: Please refer to Figure 1-Figure 8 This embodiment is a further improvement on the third embodiment, and the improvement lies in that a baffle 13 is slidably installed on the uppermost side of the left side shell 100, and there is a gap between the upper side of the baffle 13 and the lower transparent portion 60. The lower side of the baffle 13 passes through the side shell 100, and a fixing plate 14 is fixedly installed on the lower side of the baffle 13. A spring 15 is fixedly installed on the side of the fixing plate 14 facing the side shell 100, and the upper end of the spring 15 is fixedly connected to the side shell 100.

[0032] During the reciprocating movement of the pressure plate 12, when the pressure plate 12 moves downward, it will drive the transparent part 60 on the lower side to contact the baffle 13, so that the baffle 13 and the fixed plate 14 move downward synchronously and stretch the spring 15. Through the above action, the left end of the storage shell 10 is closed to a certain extent, causing the water flow output from the nozzle 9 to move downward to the right when it is pressurized, so that the pressure of the water flow is further increased, thereby reducing the impact on the power generation efficiency of the photovoltaic panel 2.
