Description

TECHNICAL FIELD

[0001] The utility model relates to photovoltaic panel cleaning tool technical field, concretely relates to a photovoltaic panel cleaning brush. BACKGROUND

[0002] With the rapid development of photovoltaic power generation technology, the cleaning problem of photovoltaic panel gradually becomes an important factor influencing the power generation efficiency. The dust, sand, bird droppings and other pollutants on the surface of photovoltaic panel, if not removed in time, will greatly reduce the photoelectric conversion efficiency of photovoltaic panel, and even may cause physical damage to photovoltaic panel. At present, the common photovoltaic panel cleaning methods on the market mainly include manual cleaning, mechanical wiping and high-pressure water gun cleaning, but these methods have some problems in practical application, such as low efficiency, high labor intensity, easy to scratch the surface of photovoltaic panel, etc. At present, there are some technical solutions based on brushing or automatic cleaning, but most of the equipment is complex in design, high in cost or limited in application range. In addition, the cleaning effect of the existing cleaning tools is quite different under different environments.

[0003] Referring to the prior art CN221581420U, a photovoltaic panel cleaning device, comprising a support plate, a connecting pipe is rotatably connected to the support plate, a linear motor sliding table is arranged on the bottom of the support plate on both sides, and a cleaning box is slidably connected to the two linear motor sliding tables. The support plate bottom is provided with a connecting pipe, the cleaning box top is provided with a water distribution box, and the water distribution box is communicated with the connecting pipe. The cleaning box comprises a box body, a plurality of water inlet holes are arranged on the top of the box body, the water inlet holes are communicated with the water distribution box, and a flexible sponge is arranged in the box body.

[0004] The flexible sponge inside the cleaning box is continuously flushed by the water outlet pipe, so that the sponge is wet and the dirt and dust on the surface of the photovoltaic panel are cleaned. However, the number of sponge rubs in the prior art is only one, which reduces the cleaning efficiency, and if the number of sponge rubs is increased,

[0005] And the wetness of the plurality of sponge rubs is controlled, for example, a sponge rub with higher humidity is used to wet the pollutants on the photovoltaic panel, and a sponge rub with lower humidity or dry sponge rub is used to wipe the lubricated pollutants (the friction between the sponge rub with lower humidity or dry sponge rub and the photovoltaic panel is larger), which can certainly improve the cleaning efficiency. UTILITY MODEL CONTENTS

[0006] The utility model intends to provide a photovoltaic panel cleaning brush to provide a cleaning brush for controlling the humidity of a plurality of sponge rubs.

[0007] In order to achieve the above purpose, the utility model provides the following technical scheme:

[0008] A photovoltaic panel cleaning brush comprises a cleaning box and a hollow handle, the handle and the cleaning box are hinged, the cleaning box is symmetrically provided with a cleaning port, the cleaning port is rotationally connected with a roller shaft, and the roller shaft is fixedly sleeved with a sponge wipe; a three-way pipe is fixedly arranged in the cleaning box, the three-way pipe comprises a horizontal end and a vertical end, the horizontal ends on both sides are respectively provided with a valve for supplying water to the corresponding sponge wipe; and a water supply hose is communicated through the handle and the vertical end.

[0009] The working principle and beneficial effects of the photovoltaic panel cleaning brush are as follows:

[0010] The sponge wipes on both sides contact the photovoltaic panel through the hand-held handle, the sponge wipes are driven to rotate to clean by pushing the handle, the water supply hose is supplied with cleaning liquid when the valves on both sides are opened, and the cleaning liquid is supplied to the corresponding sponge wipe through the vertical end and the horizontal end to wet the sponge wipe. When it is necessary to adjust the wetness of the sponge wipe on one side, for example, the valve on the left horizontal end is closed, the water supply to the sponge wipe on the left side is stopped, the wetness of the sponge wipe on the left side is reduced during wiping, the friction between the sponge wipe and the photovoltaic panel is increased, and the sponge wipe on the right side is kept supplied with water, that is, the photovoltaic panel is wiped by the sponge wipes in an alternating dry and wet manner, and better cleaning effect is achieved.

[0011] The number of sponge wipes is increased to two in the photovoltaic panel cleaning brush, and the water supply to the two sponge wipes can be controlled through the valves, that is, the dry and wet degrees of the sponge wipes on both sides are controlled, and better cleaning effect is achieved.

[0012] In some embodiments, the horizontal end is communicated with a branch pipe parallel to the axis of the sponge wipe, and the branch pipe is provided with a water supply port for supplying water to the sponge wipe. The water supply capacity to the sponge wipe is increased by using the branch pipe, and the sponge wipe is better wetted.

[0013] In some embodiments, the length of the water supply port is greater than the length of the sponge wipe. This optimization scheme can quickly wet the sponge wipe.

[0014] In some embodiments, the handle comprises a plurality of grip rods which are inserted into each other. This optimization scheme can adjust the length to a reasonable length according to the use requirement.

[0015] In some embodiments, the length of the roller shaft is greater than or equal to the length of the sponge wipe.

[0016] In some embodiments, the sponge wipe is provided with a concave and convex friction surface. The concave and convex friction surface can better clean the photovoltaic panel. BRIEF DESCRIPTION OF DRAWINGS

[0021] The reference numerals in the accompanying drawings include: handle 1, water hose 2, cleaning box 3, roller 4, sponge 5, valve 6, tee pipe 7, branch pipe 8, water inlet 9.

[0022] In the following statements, directional terms such as "left," "right," "up," and "down" are based on the directions shown in the diagram. In practice, if the corresponding structures are changed in the same direction based on the direction while maintaining their relative positions, it will not affect the implementation of the plan.

[0023] Example: A photovoltaic panel cleaning brush, such as Figure 1 As shown, it includes a cleaning box 3 and a hollow handle 1, with the handle 1 and the cleaning box 3 hinged together by a pin. Figure 2 As shown, the cleaning box 3 is symmetrically provided with cleaning ports on the left and right sides. The cleaning ports are rotatably connected to rollers 4 through bearings, and sponge wipes 5 are fixedly sleeved on the rollers 4.

[0024] like Figure 3 As shown, a three-way pipe 7 is fixedly installed inside the cleaning box 3. The three-way pipe 7 includes two horizontal ends and a vertical end. The horizontal ends are respectively fixedly connected to branch pipes 8. The branch pipes 8 are provided with water inlets 9 that supply water to the corresponding sponge 5. Valves 6 are installed on the horizontal ends respectively. The valves 6 are butterfly valves of model D71X-Q / C produced by Dingxin Valve Co., Ltd. Butterfly valves, also known as flap valves, are a simple regulating valve that can be used for the on / off control of low-pressure pipeline media. A butterfly valve is a valve in which the closing element (valve disc or butterfly plate) is a disc that rotates around the valve shaft to achieve opening and closing. It also includes a water supply hose 2 that passes through the handle 1 and is fixed and connected to the vertical end.

When in use, the valves 6 on both sides are opened, the water supply hose 2 is connected with the cleaning liquid, the cleaning liquid flows to the branch pipes 8 through the vertical end and the horizontal end respectively, and then flows to the corresponding sponge wiper 5 through the water supply port 9 to be wetted. When it is needed to adjust the wetness of the sponge wiper 5 on one side, for example, the valve 6 of the horizontal end on the left side is closed, the water supply to the sponge wiper 5 on the left side is stopped, the wetness of the sponge wiper 5 on the left side is lowered during wiping, the friction between the sponge wiper 5 on the left side and the photovoltaic panel is increased, and the sponge wiper 5 on the right side keeps being supplied with water, that is, the photovoltaic panel is wiped through dry and wet alternation, so that better cleaning effect is achieved. The device is especially suitable for the following use: the sponge wiper with high wetness is used to wet the pollutants on the photovoltaic panel, and then the sponge wiper 5 with low wetness or dryness is used to wipe the lubricated pollutants (the friction between the sponge wiper 5 with low wetness or dryness and the photovoltaic panel is greater), so that the cleaning efficiency is improved.

[0026] In another embodiment, the handle 1 comprises a plurality of jointed holding rods. The optimization scheme can be adjusted to a reasonable length according to the use requirement.
