[0002] In order to ensure the strength, rigidity and installation operability of the lattice plate as a whole, the size of the lattice plate is limited, so when laying a large area of solar panels, multiple lattice plate units are usually used for splicing, and gaps are inevitably generated between the lattice plate units. Thus, when the cleaning device is working, the panel gap will affect the smoothness of the cleaning device, and even cause weightlessness, jamming or anchoring, etc.
[0003] For a tracked cleaning device with wheeled walking, the solar frame is used as a guide, especially the upper frame guide mechanism, which not only serves as a guide but also bears a certain gravity component.

When walking to the panel gap, the cleaning device is easy to lose balance, the guide mechanism loses its guiding effect, and the above-mentioned problems such as insufficient walking smoothness, weightlessness, jamming or anchoring, etc. may occur. Even after crossing the gap obstacle, the walking wheel deviates due to deviation, causing the walking to deviate from the original trajectory, and the cleaning area cannot achieve the preset full coverage cleaning goal. Therefore, the cleaning work of the cleaning device is not reliable.

DETAILED DESCRIPTION
[0024] Exemplary embodiments will now be described more fully with reference to the accompanying drawings. However, these exemplary embodiments can be implemented in many forms and should not be construed as limited to the embodiments set forth herein; rather, they are provided so that this disclosure will be thorough and complete, and will fully convey the concept of the exemplary embodiments to those skilled in the art. The same reference numerals in the drawings denote the same or similar parts, and therefore repeated descriptions of them will be omitted.
[0025] In this example embodiment, a solar panel cleaning device capable of traversing obstacles between panels is first provided; Reference Figs. 1-3 As shown, the cleaning device includes a controller, a cleaning track 1, a base frame 9, four sets of wheels 10, and two track rollers 5. The two or four sets of wheels 10 are self-driving wheels, electrically connected to the controller. One of the track rollers 5 is the driving roller. The cleaning track 1 is fitted onto the two track rollers 5 at both ends and driven by the track rollers 5 to rotate and clean along the width of the solar panel 8. Under the elastic support of the wheels 10, the lower surface of the cleaning track 1 is in contact with the inclined surface of the solar panel 8. The track rollers 5 are mounted on roller seats 2 at both ends of the base frame 9. The base frame 9 is an integral structure, supported by the four sets of wheels 10, and self-driving along the length of the solar panel 8.
[0026] According to one aspect of this disclosure, a solar panel cleaning device capable of overcoming obstacles between panels is provided, wherein the guiding mechanism is improved to enable it to overcome obstacles, such as... Figs. 1-3 As shown, two upper guide mechanisms 3 are provided on one end of the base frame 9 near the upper frame. The two upper guide mechanisms 3 are installed on both sides of the roller seat 2 at the end of the base frame 9 and are symmetrically located on both sides of the center of the base frame 9 structure. The upper guide mechanism 3 includes a guide bracket 31 and an upper guide wheel 32. There are at least two upper guide wheels 32. Considering the design limitations of the device's self-weight, two are preferred in this embodiment. The upper end of the guide bracket 31 is screwed to the base frame 9, and the lower end is bent to form a horizontal bracket parallel to the upper frame. All upper guide wheels 32 are arranged in parallel and can be rotatably installed below the horizontal bracket. The upper guide wheels 32 serve as support and guide. The central axis of all upper guide wheels 32 is located on the same plane parallel to the side of the upper frame, so that the wheel surfaces can all roll in contact with the side of the upper frame. At the same time, the guide center distance D between the two outermost upper guide wheels 32 is greater than the plate gap, ensuring that during the obstacle crossing process, one upper guide wheel 32 in the upper guide mechanism 3 of the obstacle crossing always contacts the upper frame for support and guidance, and it forms at least two points of support with the other upper guide mechanism 3, ensuring the stability of the sweeping device's support and guidance.
[0027] Meanwhile, two lower guide mechanisms 4 are provided at the other end of the base frame 9. The two lower guide mechanisms 4 are installed on both sides of the roller seat 2 at the end of the base frame 9 and are symmetrically located on both sides of the center of the base frame 9 structure. The lower guide mechanism 4 includes an adjustment component and a lower guide wheel 41. The adjustment component can adjust the distance between the lower guide wheel 41 at its end and the upper guide wheel 32 so that the cleaning device can be installed on the upper plate. The adjustment component is connected to the base frame 9. After the upper plate is installed, the distance between the lower guide wheel 41 and the lower frame of the solar panel 8 is adjusted by the adjustment component so that the wheel surface of the guide wheel is in contact with the side of the lower frame and rolls to cooperate with the upper guide wheel to achieve linear guidance along the length of the solar panel 8.
[0028] In this example embodiment, the adjustment component includes a guide adjustment rod 6, which is an electric push rod. The other end plate of the base frame 9 extends outward and is provided with a mounting hole. The guide adjustment rod 6 is inserted and fixed in the mounting hole and is arranged on the side of the base frame 9 parallel to the width direction of the solar panel 8. The guide adjustment rod 6 is electrically connected to the controller. After the plate is installed, the guide adjustment rod 6 may have an axial pressure sensor built in it. After the lower guide pressure is preset, the guide adjustment rod 6 is activated to automatically achieve the fitting limit.
[0029] In addition, the guide adjustment rod 6 can be used for skew adjustment. Each upper guide mechanism 3 has a shaft pin pressure sensor built into at least the outermost two upper guide wheels 32 to detect the force on the upper guide wheels 32. When skew occurs, one or more upper guide wheels 32 in one guide mechanism are suspended, and the pressure data decreases. The controller analyzes the skew according to the walking speed and the preset plate spacing, and sends a contraction signal to the corresponding guide adjustment rod 6 to apply an adjustment force opposite to the skew direction until the cleaning device is reset to the same upper guide pressure. It is then considered that the cleaning device has returned to the straight walking state along the length direction, the adjustment stops, and the lower guide pressure of the lower guide mechanism 4 is adjusted evenly.
[0030] In an exemplary embodiment of this disclosure, in order to prevent the device from derailing, the wheel surface of the upper guide wheel 32 is U-shaped, its inner width is adapted to the upper frame, and it has a certain depth; at the same time, considering the adaptability of the solar panel 8, the wheel surface of the lower guide wheel 41 is also U-shaped, and its inner width is adapted to the thickness of the lower frame plus the upper limit distance above the lower frame and the lower limit distance below the lower frame.
[0031] In one exemplary embodiment of this disclosure, to prevent weightlessness and skew when one side of the walking wheel assembly 10 travels to the gap between the plates, the walking wheel assembly 10 on the same side of the base frame 9 is offset to the innermost upper guide wheel 32. Alternatively, the center line A of the walking rotation of the walking wheel assembly 10 on one side of the base frame 9 is located between the upper guide wheels 32 on that side, so as to ensure that the cleaning device has at least one support point on that side when the walking wheel assembly 10 passes over the obstacle. Considering the overall compactness of the device and to obtain a sufficiently large cleaning area, this embodiment prefers the latter design scheme, and the distance between the center line A of the walking rotation of the walking wheel assembly 10 and the outermost upper guide wheel 32 is greater than the gap between the plates.
[0032] In addition, the lower guide center line B of the lower guide wheel 41 is offset outside the travel rotation center line A so that the applied adjustment force forms a correction torque.
[0033] In one exemplary embodiment of this disclosure, since the guide adjustment rod 6 can only be adjusted along the width direction, in order to adjust the position coordinates of the lower guide wheel 41 along the length and vertical directions, the adjustment assembly further includes an adapter clamp 61 and a guide shaft 42, as shown below. Fig. 2 As shown, the adapter clamp 61 is located at the drive end of the guide adjustment rod 6, and an elastic clamping hole is vertically opened on it. The guide shaft 42 is Z-shaped, and it is bent to form two vertical shafts at both ends and a horizontal shaft in the middle. The upper vertical shaft of the guide shaft 42 passes through the elastic clamping hole, and it can be rotated and adjusted up and down. The lower guide wheel 41 is rotatably set on the lower vertical shaft of the guide shaft 42. After the adjustment is completed, tighten the clamping screw group on the adapter clamp 61, and the elastic clamping hole shrinks to clamp and lock the upper vertical shaft of the guide shaft 42.
[0034] In an exemplary embodiment of this disclosure, several correction rollers 12 are rotatably mounted on the roller seats 2 at both ends of the base frame 9. The correction rollers are arranged in groups of two to correct the deviation of the cleaning track 1. The number of correction rollers is not less than two groups, ensuring that at least one set of correction rollers is provided at each end of the cleaning track 1. The two correction rollers 12 in the same group are symmetrically located on both sides of the cleaning track 1. A limit distance is preset between the roller surface and the adjacent side of the cleaning track 1 so that the track can reliably drive the cleaning track 1 while reducing the influence of the lateral force caused by the deviation of the cleaning track 1 on the walking direction.
[0035] In one exemplary embodiment of this disclosure, when the cleaning device travels to the edge of the solar panel 8, a positioning monitor 11 is provided to prevent the upper guide mechanism 3 at the front end from completely derailing. Fig. 2As shown, the position monitor 11 uses radar sonar for edge line monitoring. The position monitor 11 is installed on the support frame 7 of the base frame 9, and position monitors 11 are installed on both sides of the support frame 7. Since the support frame 7 is installed across the clean track 1, it is beneficial to expand the radar sound wave monitoring range. The position monitor 11 feeds back the edge line signal in front of the travel to the controller, and the controller sends the corresponding control signal to the travel wheel set 10.
