Description

Technical Field

[0001] This invention belongs to the field of photovoltaic panel cleaning technology, specifically relating to a photovoltaic panel cleaning device with a cleaning inclined roller. Background Technology

[0002] With the rapid development of renewable energy, solar photovoltaic power generation, as a clean and renewable energy form, has been widely used. However, photovoltaic panels, operating outdoors for extended periods, are susceptible to contaminants such as dust, dirt, bird droppings, and leaves. These contaminants covering the surface of the photovoltaic panels reduce their ability to receive sunlight, thus affecting power generation efficiency. Traditional cleaning devices are generally not very efficient, leaving contaminant residues, and manual cleaning requires significant manpower and resources. Summary of the Invention

[0003] In view of the above-mentioned problems in the prior art, the purpose of the present invention is to provide a photovoltaic panel cleaning device with a cleaning inclined roller.

[0004] The present invention provides the following technical solution: a photovoltaic panel cleaning device with a cleaning inclined roller, comprising a housing, the housing being movably mounted on a photovoltaic panel, and cleaning devices for cleaning the photovoltaic panel being provided on both sides of the housing, and a cleaning roller for wiping the cleaned photovoltaic panel inside; the cleaning device includes a rotatable cleaning inclined roller, the axis of the cleaning inclined roller being set at an angle to the width direction of the photovoltaic panel, and a set of patterns being provided on its outer peripheral surface, with grooves formed between adjacent patterns; the housing is also provided with a water tank and a set of water spray pipes connected to the water tank, the outlet of the water spray pipes facing the surface of the photovoltaic panel in front of the cleaning inclined roller.

[0005] Furthermore, the angle between the axis of the cleaning roller and the width direction of the photovoltaic panel is 10°-20°; a set of patterns on the cleaning roller are evenly distributed along the axial direction of the roller, and the patterns are diamond-shaped.

[0006] Furthermore, the cleaning roller is mounted on the brush cover and driven to rotate by the first motor, and the brush cover is connected to the housing through a connector.

[0007] Furthermore, a drive mechanism is provided inside the housing, the drive mechanism including a walking wheel, and the walking wheel and the cleaning roller are driven to rotate synchronously by a motor.

[0008] Furthermore, the axis of the cleaning roller is set along the width direction of the photovoltaic panel, and its outer surface is a smooth surface.

[0009] Furthermore, the housing is movably mounted on a guide rail on the side of the photovoltaic panel via a set of support wheel structures. The support wheel structure includes a support wheel base mounted on the housing, a horizontal roller that is rolled in a sliding groove on the outside of the guide rail, and a set of vertical rollers that are in contact with the upper and lower surfaces of the photovoltaic panel.

[0010] Furthermore, a set of water pipes is connected to both sides of the water tank, and the lengths of the set of water pipes on the same side are different.

[0011] Furthermore, both the cleaning slant roller and the cleaning drum are made of anti-static nylon.

[0012] Furthermore, an angle sensor is provided on the outer side of the support wheel structure to detect whether the cleaning device moves along the guide rail.

[0013] Furthermore, the water tank is equipped with a pressure sensor for measuring the water tank pressure, and the housing is equipped with a photoelectric sensor for measuring the distance from the cleaning device to the end of the cleaning stroke.

[0014] By employing the above-described technology, the beneficial effects of the present invention compared to the prior art are as follows: 1) The device of the present invention adopts a structural design that combines a cleaning slanted roller and a non-tilted cleaning roller. The cleaning slanted roller brushes the surface of the photovoltaic panel with the assistance of water spraying, and the non-tilted cleaning roller wipes the surface to remove the water stains remaining after brushing, thereby reducing secondary pollution caused by water stain evaporation and maintaining the light transmittance performance of the photovoltaic panel surface. 2) In this invention, the axis of the cleaning roller is at a set angle to the width direction of the photovoltaic panel. When the roller rotates, while brushing the surface of the photovoltaic panel, it can guide the dust, sand and other pollutants brushed off along the roller axis toward one side edge of the photovoltaic panel, which helps to collect the pollutants in a specific area for subsequent centralized treatment. 3) In this invention, the surface of the cleaning roller is patterned, so that grooves are formed between adjacent patterns. The pattern structure enhances the physical scraping effect between the bristles and the stains on the board surface, which is beneficial to removing firmly attached dirt. The groove structure can store and guide water flow when the roller rotates, so that the cleaning liquid is more evenly distributed in the brushing area, thereby playing a continuous lubricating and auxiliary rinsing role during the brushing process.

[0016] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0017] Conversely, this invention encompasses any substitutions, modifications, equivalent methods, and solutions made within the spirit and scope of the invention as defined in the claims. Furthermore, to provide a better understanding of the invention, certain specific details are described in detail below. However, those skilled in the art will fully understand the invention even without these detailed descriptions.

[0018] Please see Figure 1-5 A photovoltaic cleaning device with a cleaning roller includes a housing, which includes a first housing 26 and a second housing 5. The first housing 26 has a triangular structure and is stable. Cleaning devices 1 are provided on both sides of the first housing 26, and the two cleaning devices 1 are parallel to each other. Inside the first housing 26, there is a drive mechanism and a cleaning roller 27 with no tilt angle.

[0019] Specifically, the cleaning device 1 includes a first motor 10, a roller brush housing 12, and a cleaning roller 28. The roller brush housing 12 is connected to the first housing 26 via a first connector 13 and a second connector 31. The cleaning roller 28 is rotatably mounted inside the roller brush housing 12 via a bearing. The first motor 10 is fixed to one side of the roller brush housing 12. The output end of the first motor 10 is connected to one end of the cleaning roller 28 to drive the cleaning roller 28 to rotate, thereby achieving the cleaning effect.

[0020] Specifically, the angle between the axis of the cleaning roller 28 and the width direction of the photovoltaic panel 2 is 15°. The angle can be adjusted according to actual needs and the type of contaminants. The surface of the cleaning roller 28 has diamond patterns and grooves. The grooves are 0.5cm wide and 0.25cm deep.

[0021] Specifically, four sets of support wheel structures 6 are provided on the outer side of the first housing 26. The support wheel structure 6 includes horizontal rollers 21, support wheel bases 32 and vertical rollers 23. The support wheel bases 32 are fixed to the outer side of the first housing 26 and include an upper connecting part and a lower U-shaped mounting part. The connecting part is fixedly connected to the first housing 26 by screws. The U-shaped mounting part is provided with horizontal rollers 21 inside. The side of the photovoltaic panel 2 is fixed with a guide rail 25. The horizontal rollers 21 are rolled in the groove of the guide rail. The outer end of the U-shaped mounting part is provided with two lower vertical rollers and one upper vertical roller. The two lower vertical rollers are in contact with the lower end surface of the photovoltaic panel 2, and the upper vertical roller is in contact with the upper end surface of the photovoltaic panel 2.

[0022] The photovoltaic cleaning device is fixed to the photovoltaic panel 2 by the support wheel structure 6 to prevent it from falling, and the horizontal roller 21 is guided to move along the cleaning direction by the guide rail 25.

[0023] Specifically, the drive mechanism is located inside the first housing 26, and includes a traveling wheel 14, a second motor 16, a drive wheel 17, a synchronous belt 19, a first synchronous pulley 33, and a second synchronous pulley 34.

[0024] The output shaft of the second motor 16 is fixedly connected to the drive wheel 17, driving the synchronous belt 19 to move. The synchronous belt 19 simultaneously meshes with the drive wheel 17, the first synchronous pulley 33, and the second synchronous pulley 34. The first synchronous pulley 33 is coaxially fixedly connected to the traveling wheel 14, transmitting power to the traveling wheel 14 and driving the entire device to move on the guide rail 25. The second synchronous pulley 34 is coaxially fixedly connected to the cleaning roller 27 with no tilt angle, transmitting power to the cleaning roller 27 and driving it to rotate to wipe the surface of the photovoltaic panel. By setting different numbers of teeth on the drive wheel 17, the first synchronous pulley 33, and the second synchronous pulley 34, a specific transmission ratio is achieved between the traveling wheel 14 and the cleaning roller 27, so that the rotational speed of the cleaning roller 27 is higher than that of the traveling wheel 14.

[0025] In this embodiment, the transmission ratio between the first synchronous pulley 33 and the drive pulley 17 is 1:1, and the transmission ratio between the second synchronous pulley 34 and the drive pulley is 3:1; and a first tensioning pulley 15 and a second tensioning pulley 18 are also provided on both sides of the synchronous belt 19 to prevent the belt from slipping.

[0026] Specifically, the second outer shell 5 is fixed around the first outer shell 26, with a certain gap between them. A water tank 4 and a battery 7 are mounted on top of the second outer shell 5. Three water spray pipes 3 are fixed on both sides of the second outer shell 5, and the lengths of the three water spray pipes 3 on the same side are different, requiring the length of the water spray pipes to be set according to the distance to be delivered to the front of the cleaning device 1. The water spray pipes 3 are connected to the water tank 4, which is equipped with a pressure sensor 9 to measure the water tank pressure. Symmetrical photoelectric sensors 8 for measuring the distance to the endpoint are mounted on the side of the second outer shell 5. The pressure sensor 9 can monitor the water level in the tank in real time, and the photoelectric sensor 8 stops the movement when it measures the distance to the endpoint.

[0027] The working process of the photovoltaic panel cleaning device provided in this embodiment is as follows: S1. Install the cleaning device on the guide rail 25 on the side of the photovoltaic panel 2, and start the device to enable the battery 7 to start supplying power.

[0028] S2. Control (can be controlled by a water pump) the water in the water tank 4 to spray water onto the surface of the photovoltaic panel 2 in front of the cleaning roller 28 via the spray pipe 3.

[0029] S3. The second motor 16 starts, driving the traveling wheel 14 to rotate via the drive wheel 17, synchronous belt 19, and first synchronous pulley 33, causing the device to move along the guide rail 25. At the same time, the first motor 10 starts, driving the cleaning roller 28 to rotate.

[0030] S4. The cleaning roller 28 rotates and scrubs the surface of the photovoltaic panel 2 in the area moistened by spraying water.

[0031] S5. While the device is moving, the second motor 16 drives the cleaning roller 27 without tilt angle to rotate via the synchronous belt 19 and the second synchronous pulley 34 to wipe the surface of the photovoltaic panel 2.

[0032] S6. During the operation of the device, the tilt sensor 20 monitors the operating attitude, and the photoelectric sensor 8 monitors the distance between the device and the end point of the cleaning stroke.

[0033] S7. When the photoelectric sensor 8 detects that the device has reached the destination, the device stops moving, spraying water and brushing.

[0034] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
