Description

Technical Field

[0001] This utility model relates to the field of photovoltaic panel technology, specifically to a controllable cleaning structure for photovoltaic panels. Background Technology

[0002] Photovoltaic panels are devices that convert solar energy into electrical energy. They consist of multiple solar photovoltaic panels and are widely used in residential, commercial, and industrial fields. When paired with batteries, they are widely used in areas without electricity, such as communication base stations and remote rural areas.

[0003] Photovoltaic panels are used outdoors for extended periods. If they are not cleaned regularly, dust and other debris will accumulate on their surface, affecting their power generation efficiency. Since photovoltaic panels are often installed on upper floors or in uninhabited areas, cleaning them is costly for staff. Utility Model Content

[0004] This invention provides a controllable cleaning structure for photovoltaic panels, which solves the problems mentioned in the background art.

[0005] To solve the above-mentioned technical problems, the technical solution of this utility model is as follows:

[0006] An embodiment of this utility model provides a controllable cleaning structure for photovoltaic panels, including a support frame, and further comprising:

[0007] Solar photovoltaic panels, installed on top of a support frame, convert solar energy into electrical energy;

[0008] Side baffles are fixed to both sides of the solar photovoltaic panel;

[0009] A cleaning structure is installed on one side of a solar photovoltaic panel. The cleaning structure includes a dual-output shaft geared motor fixed to the bottom of one side of the solar photovoltaic panel, a transmission shaft installed at the output shaft end of the dual-output shaft geared motor, a drive sprocket fixed to one end of the transmission shaft, a transmission chain meshing with the outside of the drive sprocket, a driven wheel rotatably connected to the inside of the transmission chain, elastic tensioners installed on both sides of the side baffle and meshing with the transmission chain, and a cleaning assembly set at the top of the side baffle.

[0010] The collection mechanism, located on the other side of the solar photovoltaic panel, is used to collect swept-down debris and rainwater;

[0011] A sunshade, placed at the top of the collection mechanism, is used to reduce the evaporation of liquid inside the collection mechanism and prevent the cleaning structure from oxidizing and deforming.

[0012] Furthermore, the cleaning assembly includes a track fixed to the top of the side baffle, a movable sprocket meshing between the track and the drive chain, a cleaning roller mounted on one side of the movable sprocket, and bristles fixed to the outside of the cleaning roller.

[0013] The above technical solution uses a dual-output shaft geared motor to drive the transmission chain in a cyclical motion, and a moving sprocket to drive the cleaning roller to thoroughly clean the solar photovoltaic panels.

[0014] Furthermore, the collection mechanism includes a fixing frame installed on one side of the bottom of the solar photovoltaic panel, a collection trough installed on the top of the fixing frame, a sewage hopper fixed to the bottom of the collection trough, and a valve installed at the bottom of the sewage hopper.

[0015] The above technical solution collects rainwater through a collection tank, improving water resource utilization efficiency. At the same time, the sewage hopper gathers sludge to the valve, so that the valve can discharge the sewage in a centralized manner.

[0016] Furthermore, the bristles are arranged in several groups on the outside of the cleaning roller, and the several groups of bristles are distributed at equal intervals on the outside of the cleaning roller.

[0017] The above technical solution ensures that the bristles are evenly spaced, which guarantees uniform contact between the cleaning roller and the photovoltaic panel surface, improves cleaning efficiency, and avoids localized wear.

[0018] Furthermore, the driven wheel and the collection tank form a rotating structure, and the driven wheel is symmetrically distributed on both sides of the collection tank.

[0019] The above technical solution, with the driven wheel and the collection tank rotating structure arranged symmetrically, enhances transmission stability and makes the cleaning components run more smoothly.

[0020] Furthermore, the side view cross-section of the sewage hopper has a funnel-shaped inclined structure.

[0021] Through the above technical solution, the sewage hopper adopts a funnel-shaped inclined surface design, which effectively collects the dirt generated during the cleaning process, and works with valves to achieve efficient discharge, preventing dirt accumulation from affecting the cleaning effect.

[0022] The above-described solution of this utility model has at least the following beneficial effects:

[0023] 1. This utility model uses a dual-output shaft geared motor to drive a transmission chain in a cyclical motion, and a moving sprocket to drive a cleaning roller to thoroughly clean the solar photovoltaic panels. This achieves the surface cleaning function of the device, enabling thorough cleaning without dead angles, preventing stains from corroding surface materials, improving power generation efficiency, and reducing manual intervention, labor intensity, and equipment wear and tear through automated operation.

[0024] 2. This utility model collects rainwater through a collection trough and uses rainwater for cleaning operations, thereby reducing the consumption of fresh water resources. At the same time, the sewage discharge hopper gathers sludge to the valve, so that the valve can discharge the sewage in a concentrated manner and avoid the accumulation of sewage.

[0032] Exemplary embodiments of the present invention will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the present invention are shown in the drawings, it should be understood that the present invention may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this invention will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.

[0033] like Figures 1 to 5 As shown, an embodiment of this utility model provides a controllable cleaning structure for photovoltaic panels, including a support frame 1, and further comprising:

[0034] Solar photovoltaic panels 4 are installed on the top of the support frame 1 to convert solar energy into electrical energy;

[0035] Side baffles 2 are fixed to both sides of the solar photovoltaic panel 4;

[0036] The cleaning structure 3 is installed on one side of the solar photovoltaic panel 4. The cleaning structure 3 includes a dual-output shaft reduction motor 303 fixed to the bottom of one side of the solar photovoltaic panel 4, a transmission shaft 304 installed at the end of the output shaft of the dual-output shaft reduction motor 303, a drive sprocket 302 fixed to one end of the transmission shaft 304, a transmission chain 301 meshing with the outside of the drive sprocket 302, a driven wheel 307 rotatably connected to one side of the transmission chain 301, an elastic tensioner 310 installed on both sides of the side baffle 2 and meshing with the transmission chain 301, and a cleaning assembly set at the top of the side baffle 2.

[0037] Collection mechanism 5 is located on the other side of solar photovoltaic panel 4 and is used to collect swept-down foreign objects and rainwater;

[0038] The sunshade 6 is set at the top of the collection mechanism 5 to reduce the evaporation of liquid inside the collection mechanism 5 and prevent the cleaning structure 3 from oxidizing and deforming.

[0039] like Figures 1 to 4 As shown, the cleaning assembly includes a track 305 fixed to the top of the side baffle 2, a movable sprocket 306 meshing between the track 305 and the drive chain 301, a cleaning roller 308 installed on one side of the movable sprocket 306, and bristles 309 fixed on the outside of the cleaning roller 308. Several groups of bristles 309 are arranged on the outside of the cleaning roller 308, and the several groups of bristles 309 are evenly distributed on the outside of the cleaning roller 308. A rotating structure is formed between the driven wheel 307 and the collection tank 501. The driven wheel 307 is symmetrically distributed on both sides of the collection tank 501.

[0040] In this embodiment of the utility model, within a set time period, the dual-output shaft reduction motor 303 is automatically started by the program, causing its output shaft to drive the transmission shaft 304 to rotate, thereby driving the drive sprocket 302 to rotate. The drive sprocket 302 causes the transmission chain 301 to circulate through the meshing of the chain teeth, and the transmission chain 301 pulls the moving sprocket 306 to move along the chain track 305, and the moving sprocket 306 drives the cleaning roller 308 to rotate. The bristles 309 evenly distributed on the outer side of the cleaning roller 308 contact the surface of the solar photovoltaic panel 4. The rotation and movement of the cleaning roller 308 thoroughly cleans the solar photovoltaic panel 4. The dual-output shaft reduction motor 303 drives the moving sprocket 306 to move back and forth on the surface of the solar photovoltaic panel 4, ensuring that the surface of the solar photovoltaic panel 4 always maintains a high-efficiency power generation state. The bristles 309 are made of soft material, which effectively avoids damage to the surface of the photovoltaic panel. The elastic tensioner 310 automatically adjusts the tension according to the tightness of the transmission chain 301, ensuring that the transmission chain 301 always maintains an appropriate tension during the transmission process.

[0041] like Figure 5As shown, the collection mechanism 5 includes a fixing frame 504 installed on one side of the bottom of the solar photovoltaic panel 4, a collection trough 501 installed on the top of the fixing frame 504, a sewage hopper 503 fixed at the bottom of the collection trough 501, and a valve 502 installed at the bottom of the sewage hopper 503. The side cross-section of the sewage hopper 503 has a funnel-shaped inclined structure.

[0042] In this embodiment of the utility model, the collection tank 501 can be used to store water during rainy weather, so that the cleaning roller 308 can be moistened during subsequent cleaning operations. This not only improves cleaning efficiency but also enhances water resource utilization efficiency. The dirt generated during the cleaning process falls into the collection tank 501 under the influence of gravity. The dirt and sludge are collected at the valve 502 by the sewage discharge hopper 503 at the bottom of the collection tank 501. The waste is centrally discharged by controlling the opening of the valve 502. The sunshade 6 blocks solar radiation, reduces the internal temperature of the collection tank 501, and reduces the temperature difference between the liquid surface and the air, thereby slowing down the evaporation rate and effectively retaining the liquid in the collection tank 501.

[0043] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
