Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of solar cell panels, relates to the technical field of solar cell panel surface cleaning, and specifically relates to a solar cell panel cleaning device. BACKGROUND

[0002] A solar cell panel is a device that converts solar radiation energy into electric energy through photoelectric effect or photochemical effect, and the cleanliness of the solar cell panel seriously affects the power generation efficiency. In order to ensure normal power generation function and prevent the solar cell panel from being affected by dust and stains during power generation, the solar cell panel needs to be cleaned regularly.

[0003] The existing solar cell panel cleaning device moves the cleaning instrument on the surface of the solar cell panel by a moving machine, and the surface of the solar cell panel is cleaned during the movement. However, the rolling wiping action of the roller is difficult to form sufficient local cleaning force, so that local stubborn stains cannot be effectively removed, and excessive repeated wiping of the roller will cause friction damage to the surface of the solar cell panel. Meanwhile, the cleaning device lacks precise recognition and positioning ability for local stubborn stains, and cannot timely find and deal with local stubborn stains. SUMMARY

[0004] The present application solves the technical problems that the existing cleaning device cannot effectively remove local stubborn stains, the roller causes friction damage to the surface of the solar cell panel due to excessive repeated wiping, and the local stubborn stains cannot be cleaned locally.

[0005] In order to solve the above technical problems, the present application provides the following technical scheme: a solar panel cleaning device, comprising a support seat and a support plate arranged on the support seat, wherein the support plate is provided with a solar panel, and further comprising a first driving assembly, a second driving assembly, a cleaning roller assembly, a third driving assembly and a cleaning head; the first driving assembly is arranged on the support plate and connected with the second driving assembly and the cleaning roller assembly; the first driving assembly drives the second driving assembly to move in the X-axis direction; the cleaning roller assembly moves in the X-axis direction synchronously with the second driving assembly under the driving of the second driving assembly; the cleaning roller assembly rotates under the driving of the first driving assembly and is used for cleaning the solar panel in an overall manner; the second driving assembly is connected with the third driving assembly and drives the third driving assembly to move in the Y-axis direction; the third driving assembly is connected with the cleaning head; the cleaning head moves in the Y-axis and Z-axis directions under the driving of the second driving assembly and the third driving assembly and is used for cleaning local stains of the solar panel in a targeted manner. This scheme can realize the functions of targeted cleaning and overall cleaning; the roller can move in the X-axis direction and rotate under the driving of the first driving assembly and the second driving assembly; in the moving process, the roller rotates to clean the solar panel, so that the cleaning efficiency is high and the cleaning capacity is strong. Under the driving of the first driving assembly, the second driving assembly and the third driving assembly, the cleaning head can move in the X-axis, Y-axis and Z-axis directions and move to the stain position to clean the stain in a targeted manner, so as to remove stubborn stains.

[0006] Furthermore, the cleaning roller assembly includes a cleaning roller, a first support member, a second support member, a first bevel gear, a second bevel gear, a limiting member, and a fixing member. The first drive assembly includes a first guide rod and a hollow guide rod. The hollow guide rod has a hollow groove along its length. The cleaning roller has rotating shaft portions on both sides, and the rotating shaft portions on both sides of the cleaning roller are respectively connected to the rotating holes of the first support member and the second support member. The first guide rod passes through the first support member and is used to support the first support member. The upper part of the second support member is connected to the second drive assembly, and the lower part of the second support member has a cylindrical connecting portion. The hollow guide rod passes through the cylindrical connecting portion at the lower part of the second support member. The first bevel gear has a through hole along its axis center and is rotatably fitted onto the cylindrical connecting part. The limiting member is connected to the free end of the cylindrical connecting part by screws to restrict the translation of the first bevel gear. The fixing member is set in the hollow groove and can move along the length direction of the hollow rod. The fixing member is fixedly connected to the first bevel gear by screws. The second bevel gear is fixed on the rotating shaft part on the corresponding side of the cleaning roller and meshes with the first bevel gear. The second drive assembly drives the cleaning roller assembly to translate through the second support member. The hollow rod of the first drive assembly drives the first bevel gear to rotate through the fixing member, thereby driving the cleaning roller to rotate through meshing with the second bevel gear. In this technical solution, the second drive assembly is connected to the roller assembly through the second support member. The roller assembly is driven by the second drive assembly, thereby achieving synchronous translation of the two. The rotation of the roller assembly is achieved through the meshing connection of the first and second bevel gears. This structure can realize that the roller assembly can translate and rotate at the same time, thereby enhancing the cleaning ability of the roller assembly.

[0007] Furthermore, the first drive assembly also includes a first motor bracket, on which a first motor is fixedly mounted. The first motor is fixedly connected to a first gear via a coupling. The first gear and a second gear are connected via gear meshing. The first gear is fixedly connected to a ball screw via a first bearing. A ball nut is mounted on the ball screw, and the ball nut connects to and drives the second drive assembly. The second gear is fixedly connected to a hollowed-out guide rod via a second bearing. The first and second bearings are fixed on bearing seats. The first drive assembly includes two guide rod support seats, and two first guide rods are fixedly connected between the two guide rod support seats. The two first guide rods are arranged vertically and are respectively on the same plane as the ball screw and the hollowed-out guide rod. In this scheme, the first motor drives the ball screw and the hollowed-out guide rod to rotate, thereby driving the second drive assembly to translate and the roller assembly to rotate while translating.

[0008] Furthermore, the second drive assembly also includes a first support plate, which is located above the cleaning roller assembly and its two ends are movably connected to a ball nut on one side of the first drive assembly and a first guide rod on the other side. The upper part of the second support member of the cleaning roller assembly is connected to the lower surface of the first support plate. Two ball screw support frames and a second motor support frame are fixedly installed on the upper surface of the first support plate. A second guide rod and a second ball screw are connected between the two ball screw support frames. The second ball screw is fixed between the ball screw support frames by a third bearing. A second motor is fixedly installed on the second motor support frame. The second motor is connected to the second ball screw through a second coupling. Both the second guide rod and the second ball screw pass through a second ball nut, which is connected to the third drive assembly. In this technical solution, the second motor drives the second ball screw to rotate, thereby driving the second ball nut to translate along the second guide rod and the second ball screw.

[0009] Furthermore, the third driving component is a cleaning head telescopic device, with the cleaning head mounted at its lower end. The cleaning head telescopic device allows for adjustment of the cleaning head's height, thereby changing the frictional force exerted by the cleaning head on the solar panel.

[0010] Furthermore, a camera mount is installed on the lower surface of one side of the first support plate, and the camera is fixedly mounted on the camera mount. Under the action of the first driving component, the camera moves in the X-axis direction to detect localized stains on the solar panel. In this solution, by using camera imaging, localized stains on the solar panel can be identified and located, thereby enabling the backend control of this device to achieve targeted cleaning.

[0011] Furthermore, three sets of water spray nozzles are fixedly installed on the upper surface of the other side of the first support plate. The water spray nozzles are used to clean the solar panels before the roller cleaning process.

[0012] Furthermore, the first side of the support base is rotatably connected to the first side of the support plate, and an expansion joint is provided between the second side of the support base and the second side of the support plate. The expansion joint is used to drive the second side of the support plate to rotate around the first side of the support base. This allows for adjustment of the solar panel angle, selecting a better position for sunlight, preventing insufficient sunlight, and meeting the high-efficiency power generation requirements of solar energy. Simultaneously, during cleaning, the angle of the solar panel allows wastewater to flow off, facilitating effective cleaning.

[0013] Furthermore, one end of the telescopic device is rotatably connected to the second side of the support base, and the other end is connected to a rotatable cross arm, which is fixedly installed below the support plate. The structure is simple and the cost is low.

[0014] Compared with the prior art, the present invention has the following beneficial effects: 1. Using a roller to perform large-area, reciprocating cleaning and wiping of the solar panel surface. When the large-area cleaning of the roller is incomplete and stubborn stains are not cleaned, a camera can be used to identify and locate the stains that are difficult to remove. The cleaning head moves above the stain and changes the height of the cleaning head by extending and retracting the cleaning head telescopic device, so that the cleaning head makes frictional contact with the solar panel to perform targeted cleaning of stubborn stains, strengthen the cleaning of local stains, and complete the dual cleaning effect of the whole and the part of the solar panel.

[0015] 2. The first motor drives the ball screw and the perforated guide rod to rotate simultaneously via the first and second gears. The rotation of the ball screw causes the ball nut to translate, thereby driving the second drive assembly to translate. The connection of the first support component ensures that the second drive assembly moves synchronously with the cleaning roller assembly. The perforated guide rod drives the first bevel gear to rotate, and the first and second bevel gears mesh to drive the roller to rotate. The limiting component limits the first bevel gear, allowing it to move synchronously with the first support component. The perforated groove of the perforated guide rod plays a key role in realizing the rotation and translation of the first bevel gear. The roller rotates synchronously during the translation process, achieving an efficient wiping and cleaning effect.

[0016] 3. Adjusting the angle of the support plate by using the telescopic mechanism allows for adjustment of the angle of the solar panel, enabling the selection of a better position for sunlight, preventing insufficient sunlight, and meeting the high-efficiency power generation requirements of solar energy. At the same time, during the cleaning process, the angle of the solar panel allows wastewater on the panel to flow down, which is beneficial for the effective cleaning of the solar panel.

[0023] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. It should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," etc., should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal communication between two components. For those skilled in the art, the specific meaning of the above terms in the present invention can be understood according to the specific circumstances.

[0024] Example 1, such as Figure 1 A solar panel cleaning device includes a support base 101 and a support plate 102 disposed on the support base 101. The support plate 102 is provided with a solar panel 2 and includes a first drive assembly 3, a second drive assembly 4, a cleaning roller assembly 5, a third drive assembly 7 and a cleaning head 8.

[0025] The first drive assembly 3 is mounted on the support plate 102. The first drive assembly 3 is connected to the second drive assembly 4 and the cleaning roller assembly 5. The first drive assembly 3 drives the second drive assembly 4 to translate in the X-axis direction. The cleaning roller assembly 5 translates synchronously with the second drive assembly 4 in the X-axis direction under the drive of the second drive assembly 4. The cleaning roller assembly 5 rotates under the drive of the first drive assembly 3. The cleaning roller assembly (5) is used to clean the entire surface of the solar panel 2.

[0026] Specifically, in order to achieve the translation and rotation of the cleaning roller, the present invention adopts the following specific structure: (Refer to...) Figure 4 , Figure 5 and Figure 6 The cleaning roller assembly 5 includes a cleaning roller 502, a first support member 501, a second support member 503, a first bevel gear 504, a second bevel gear 505, a limiting member 506, and a fixing member 507. (Refer to...) Figure 3 and Figure 5 The first driving component 3 includes a first light rod 313 and a hollow light rod 310, and the first driving component 3 can drive the hollow light rod 310 to rotate.

[0027] The hollowed-out light rod 310 has a hollowed-out groove along its length direction. The hollowed-out groove is a through groove along the radial direction of the hollowed-out light rod 310, which allows the fixing member 507 to pass through and allows the fixing member 507 to translate along the length direction of the hollowed-out light rod 310 in the hollowed-out groove. The cleaning roller 502 has a rotating shaft on each side. The rotating shaft on both sides of the cleaning roller 502 is connected to the rotating hole of the first support member 501 and the rotating hole 503-1 of the second support member 503, respectively. When the cleaning roller 502 rotates and translates, the inner wall of the rotating hole applies a force in the translational direction and a force in the vertical direction to the rotating shaft. The connection between the rotating shaft and the rotating hole provides support for the rotation and driving force for the translation of the cleaning roller 502.

[0028] The first optical rod 313 passes through the first support member 501 and supports the first support member 501. The first support member 501 can slide and translate along the X-axis direction on the first optical rod 313. The upper part of the second support member 503 is connected to the second drive assembly 4. The lower part of the second support member 503 is provided with a cylindrical connecting part 503-2. The cylindrical connecting part 503-2 has a through hole. The hollow optical rod 310 passes through the through hole of the cylindrical connecting part at the lower part of the second support member 503. This through hole is staggered from the rotating hole in the second support member 503 to prevent them from having an overlapping structure that would cause mutual interference. The first bevel gear 504 has a through hole along its axial center, and the cylindrical connecting part 503-2 passes through it. The first bevel gear 504 is rotatably mounted on the cylindrical connecting part by passing through the through hole. The limiting member 506 is fixedly connected to the free end of the cylindrical connecting part 503-2 by screws or set screws. Preferably, the cylindrical connecting part 503-2 is a stepped cylinder, and the limiting member 506 is preferably circular. When the cylindrical connecting part 503-2 is connected and fixed with the limiting member 506, a limiting structure is formed, which restricts the first bevel gear 504 to be mounted in this limiting structure. The first bevel gear 504 will not translate when rotating, thereby ensuring that the positions of the first bevel gear 504 and the second bevel gear 505 are fixed and a stable gear meshing connection is maintained, thereby improving the transmission stability of the roller assembly.

[0029] The fixing member 507 is disposed in the hollow groove and can move along the length direction of the hollow light rod 310. The fixing member 507 is preferably elongated, and the shape of the hollow groove is matched with the shape of the fixing member, so that the fixing member 507 can move smoothly in the hollow groove. At the same time, the fixing member 507 can also rotate under the drive of the hollow light rod. Ideally, the side of the fixing member 507 maintains a reasonable gap distance with the inner wall of the hollow groove. It should not be too large or too small. If it is too large, it will not be conducive to driving the fixing member 507 to rotate; if it is too small, it will not be conducive to driving the fixing member 507 to translate.

[0030] The fixing member 507 has a through-hole groove in the middle, and its two ends are fixedly connected to the first bevel gear 504 by screws or bolts. The second bevel gear 505 is fixed on the rotating shaft on the corresponding side of the cleaning roller 502 and meshes with the first bevel gear 504. The second drive assembly 4 drives the cleaning roller assembly to translate through the second support member 503. The through-hole rod 310 of the first drive assembly 3 drives the first bevel gear 504 to rotate through the fixing member 507, thereby causing the second bevel gear 505 to drive the cleaning roller 502 to rotate through the gear meshing connection. Preferably, in order to facilitate the installation of the limiting member 506 and the fixing member 507, an installation groove is opened on the side of the first bevel gear 504 near the limiting member 506. When the limiting member is fixedly connected to the cylindrical connecting part, it is located in the installation groove, thereby avoiding the nearby fixing member 507 and not hindering the rotation of the fixing member 507 and the first bevel gear 504.

[0031] In this embodiment, the second drive component 4 is connected to the cleaning roller 502 through the second support member 503. Therefore, the cleaning roller assembly is driven by the second drive component 4, thereby achieving synchronous translation between the two.

[0032] The first drive assembly 3 drives the hollow light rod 310 to rotate, and then the first bevel gear 504 and the second bevel gear 505 mesh to realize the rotation of the cleaning roller assembly 5. This structure can realize the cleaning roller assembly to move and rotate at the same time, thereby enhancing the cleaning ability of the cleaning roller assembly. The cleaning roller performs large-area, reciprocating cleaning and wiping on the surface of the solar panel.

[0033] The second drive component 4 is connected to the third drive component 7 and drives the third drive component 7 to translate in the Y-axis direction. The third drive component 7 is connected to the cleaning head 8. Under the drive of the first drive component 3, the second drive component 4 and the third drive component 7, the cleaning head 8 moves in the X-axis, Y-axis and Z-axis directions and moves to directly above the local stain to perform targeted cleaning of the local stain on the solar panel 2.

[0034] refer to Figure 1 and Figure 3Specifically, the first drive assembly 3 further includes a first motor bracket 301, on which a first motor 302 is fixedly mounted. The first motor 302 is fixedly connected to a first gear 304 via a coupling 303. The first gear 304 and the second gear 305 are connected by gear meshing. The first gear 304 is fixedly connected to a ball screw 307 via a first bearing 306. A ball nut 308 is mounted on the ball screw 307. The ball nut 308 connects to and drives the second drive assembly 4. The second gear 305 is fixedly connected to the hollowed-out light rod 310 via a second bearing 309. The first bearing 306 and the second bearing 309 are fixed on a bearing seat. The first drive assembly 3 includes two light rod support seats 312. Two first light rods 313 are fixedly connected between the two light rod support seats 312. The two first light rods 313 are arranged in upper and lower layers and are respectively on the same plane as the ball screw 307 and the hollowed-out light rod 310. Connected to the cleaning roller assembly are the lower first light rod 313 and the hollow light rod 310. In this embodiment, the ball screw 307 and the hollow light rod 310 are driven to rotate by the first motor 302, thereby driving the second drive assembly 4 to translate and the cleaning roller assembly to translate and rotate at the same time.

[0035] refer to Figure 4 and Figure 5Specifically, the second drive assembly 4 further includes a first support plate 402. The first support plate 402 is located above the cleaning roller assembly 5 and its two ends are movably connected to a ball nut 308 on one side of the first drive assembly 3 and a first guide rod 313 on the other side. The upper part of the second support member of the cleaning roller assembly 5 is connected to the lower surface of the first support plate 402. Two ball screw support frames 408 and a second motor support frame 409 are fixedly installed on the upper surface of the first support plate 402. A second guide rod 410 and a second ball screw 411 are connected between the two ball screw support frames 408. The second ball screw 411 is fixed between the ball screw support frames 408 by a third bearing. A second motor 417 is fixedly installed on the second motor support frame 409. The second motor 417 is connected to the second ball screw 411 by a second coupling 418. The second guide rod 410 and the second ball screw 411 both pass through a second ball nut 413. The second ball nut 413 is connected to the third drive assembly 7. In this structure, the second ball screw 413 is supported by the second guide rod 410 and the second ball screw 411, thereby supporting the third drive assembly. The structure boasts high reliability. The second motor drives the second ball screw 411, which in turn moves the second ball screw 413 along the Y-axis. The second ball screw 413 then drives the third drive assembly 7 to move in the same direction. The second drive assembly 4 is located directly above the cleaning roller assembly 5. The synchronous movement of the second drive assembly 4 and the cleaning roller assembly 5 ensures that the second drive assembly 4 remains directly above the cleaning roller assembly 5, guaranteeing that both are always moving synchronously to the same position above the solar panel 2. This ensures that the cleaning head and roller assembly can perform comprehensive cleaning of the solar panel 2.

[0036] In this embodiment, the first drive assembly 3 and the second drive assembly 4 are used to drive the cleaning roller assembly 5 to perform large-area, reciprocating cleaning and wiping of the solar panel. When the large-area cleaning of the roller is incomplete and stubborn stains are not cleaned, the first drive assembly 3, the second drive assembly 4, and the third drive assembly 7 are used to drive the cleaning head 8 to move along the XYZ three axes, move it above the local stains, and achieve the purpose of cleaning the local stains at a fixed point. The third drive assembly 7 can change the friction force of the cleaning head on the solar panel by raising and lowering the height, so as to avoid scratching the surface of the solar panel during fixed-point cleaning.

[0037] In this embodiment, preferably, refer to Figure 2The first side of the support base 101 is rotatably connected to the first side of the support plate 102. A telescopic device 103 is provided between the second side of the support base 101 and the second side of the support plate 102. The telescopic device 103 is used to drive the second side of the support plate 102 to rotate around the first side of the support base 101. Specifically, one end of the telescopic device 103 is rotatably connected to the second side of the support base 101, and the other end is connected to a rotatable horizontal arm 104, which is fixedly installed below the support plate 102. Specifically, one side of the support base 101 is rotatably connected to a support hole 105 below the support plate 102 via a fixing bolt 106. One end of the telescopic device 103 is hinged to the support base 101, and the other end of the telescopic device 103 is connected to the rotatable horizontal arm 104, allowing adjustment of the angle of the support plate 103 during operation. The rotatable horizontal arm 104 is fixedly installed below the support plate 102. Preferably, the support base 101 is a four-corner support base.

[0038] The telescopic device 103 can adjust the angle between the support plate 102 and the ground by telescopic movement, thereby adjusting the angle between the solar panel and the ground, selecting a better position for sunlight, preventing insufficient sunlight, and meeting the high-efficiency power generation requirements of solar energy. At the same time, during the cleaning process, the angle of the solar panel allows the cleaning wastewater on the solar panel to flow down at any time, which is conducive to the effective cleaning of the solar panel.

[0039] Preferably, the third drive component 7 is a cleaning head telescopic device, and the cleaning head 8 is installed at the lower end of the cleaning head telescopic device. The cleaning head telescopic device can adjust the height of the cleaning head, thereby changing the frictional force between the cleaning head and the solar panel.

[0040] It should be noted that the reference Figure 1 The orientations shown in this embodiment refer to the X-axis direction, which is parallel to the solar panel and moves left and right, i.e., the direction in which the first drive component drives the second drive component; the Y-axis direction, which is parallel to the solar panel and moves back and forth, i.e., the direction in which the second drive component drives the third drive component; and the Z-axis direction, which is perpendicular to the solar panel and moves, i.e., the direction in which the third drive component drives the cleaning head.

[0041] Example 2: Based on Example 1, as follows... Figure 3 A camera bracket 406 is mounted on the lower surface of one side of the first support plate 402. The camera 6 is fixedly mounted on the camera bracket 406. Under the action of the first driving component 3, the camera 6 moves in the X-axis direction to detect local stains on the solar panel. In this scheme, by using camera imaging, local stains on the solar panel can be identified and located, thereby enabling the backend control of this device to achieve targeted cleaning.

[0042] Preferably, three sets of water spray nozzles 414 are fixedly installed on the upper surface of the other side of the first support plate 402. The water spray nozzles are used to clean the solar panels before the roller cleaning process. Each of the three sets of water spray nozzles 416 is equipped with an electronically controlled valve to control the water spray nozzles 416 to spray water before and after the cleaning process to rinse away the dirt and dust from the solar panels 2.

[0043] This invention utilizes a cleaning roller to perform large-area, reciprocating cleaning and wiping of the solar panel surface. When the large-area cleaning of the roller is incomplete and stubborn stains are not completely removed, a camera can be used to identify and locate the stains that are difficult to remove. The cleaning head moves above the stain, and the height of the cleaning head is changed by extending and retracting the cleaning head telescopic device, so that the cleaning head makes frictional contact with the solar panel to perform targeted cleaning of stubborn stains, strengthen the focused cleaning of local stains, and achieve a dual cleaning effect of cleaning both the whole and the parts of the solar panel.
