It will be understood that the specific embodiments described herein are only used to explain the related application, rather than to limit the application. The described embodiments are only a part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without making creative work are within the scope of protection of the present application.

[0031] It should be noted that, for the convenience of description, only the parts related to the relevant application are shown in the drawings. In the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other.

[0032] See also Figure 1-Figure 5 .

[0033] Some embodiments of the present application disclose a photovoltaic panel cleaning device, including a mounting frame 1 and a cleaning mechanism 3 , wherein the cleaning mechanism 3 is mounted on the mounting frame 1 .

[0034] The mounting frame 1 can be placed across the photovoltaic panel, and a walking wheel 2 is provided at the lower end of the mounting frame 1;

[0035] The cleaning mechanism 3 is installed obliquely on the mounting frame 1 and is used to clean the photovoltaic panel. The two ends of the cleaning mechanism 3 in the length direction are connected to the mounting frame 1 through the first linear drive 4 and the second linear drive 5 respectively. The first linear drive 4 and the second linear drive 5 are used to drive the cleaning mechanism 3 to move so as to adjust the angle of the cleaning mechanism 3 and the distance between the cleaning mechanism 3 and the photovoltaic panel.

[0036] The first linear drive 4 and the second linear drive 5 are respectively connected to the two ends of the length direction of the cleaning mechanism 3. According to the adjustment requirements of the cleaning mechanism 3, the first linear drive 4 and the second linear drive 5 can work simultaneously, or only one of them can work.

[0037] The photovoltaic panel cleaning device disclosed in the present application realizes the movable connection between the cleaning mechanism 3 and the mounting frame 1 through the first linear driving member 4 and the second linear driving member 5, and adjusts the inclination angle of the cleaning mechanism 3 through the first linear driving member 4 and the second linear driving member 5, so that the inclination angle of the cleaning mechanism 3 can be adjusted according to the installation angle of the photovoltaic panel, so that the photovoltaic panel cleaning device can clean photovoltaic panels with different installation angles, thereby improving the versatility of the photovoltaic panel cleaning device; at the same time, when the photovoltaic panel cleaning device is moving on a bumpy road surface, the first linear driving member 4 and the second linear driving member 5 adjust the distance between the cleaning mechanism 3 and the photovoltaic panel, so that the distance between the cleaning mechanism 3 and the photovoltaic panel always maintains a safe distance, thereby preventing the cleaning mechanism 3 from bumping against the photovoltaic panel and reducing the risk of bumping against the photovoltaic panel.

[0038] The first linear driving member 4 and the second linear driving member 5 can be directly mounted on the mounting frame 1 , and the driving ends of the first linear driving member 4 and the second linear driving member 5 are respectively connected to the two ends of the cleaning mechanism 3 in the length direction.

[0039] In some other embodiments of the present application, the first linear drive member 4 and the second linear drive member 5 are connected to the mounting frame 1 through the vertical guide rail 6 and the guide rail assembly 7 respectively.

[0040] like Figure 1 and Figure 2 As shown, the vertical guide rail 6 is arranged along the vertical direction, the first linear drive member 4 is installed on the vertical guide rail 6 along the vertical direction, the driving direction of the first linear drive member 4 is along the vertical direction, and the driving end of the first linear drive member 4 moves along the vertical guide rail 6 and is connected to the lower end of the cleaning mechanism 3 (hereinafter referred to as the first end);

[0041] The guide rail assembly 7 includes a movable guide rail 71 and an arcuate guide rail 72. The movable guide rail 71 is arranged opposite to the vertical guide rail 6. The second linear drive member 5 is installed on the movable guide rail 71. The driving end of the second linear drive member 5 moves along the movable guide rail 71 and is connected to the higher end of the cleaning mechanism 3 (hereinafter referred to as the second end). The lower end of the movable guide rail 71 is hinged to the mounting frame 1, and the upper end of the movable guide rail 71 is slidably connected to the arcuate guide rail 72. One end of the arcuate guide rail 72 is hinged to the mounting frame 1, and the other end of the arcuate guide rail 72 is a free end.

[0042] When the first linear drive member 4 drives the first end of the cleaning mechanism 3 to move downward, the second linear drive member 5 drives the second end of the cleaning mechanism 3 to move upward, and the upper end of the movable guide rail 71 slides toward the free end of the arc guide rail 72, and the arc guide rail 72 moves downward; when the first linear drive member 4 drives the first end of the cleaning mechanism 3 to move upward, the second linear drive member 5 drives the second end of the cleaning mechanism 3 to move downward, and the upper end of the movable guide rail 71 slides in the direction away from the free end of the arc guide rail 72, and the arc guide rail 72 moves upward.

[0043] In order to prevent the arc guide rail 72 from flipping over during the upward movement, the present application sets a limiting column 8 on the installation frame 1. The limiting column 8 is connected to the installation frame 1 and is used to abut against the outer curved surface of the arc guide rail 72 when the arc guide rail 72 moves to the highest position, thereby limiting the arc guide rail 72.

[0044] Preferably, the shape of the lower end surface of the limiting column 8 is adapted to the shape of the outer arc surface of the arc guide rail 72; further, the lower end surface of the limiting column 8 is provided with an elastic pad.

At least one distance measuring sensor is disposed at the end of the cleaning mechanism 3.

[0046] Preferably, a plurality of distance measuring sensors are evenly arranged in the length direction of the cleaning mechanism 3 to detect the distances at a plurality of positions between the cleaning mechanism 3 and the photovoltaic panel, so as to improve the accuracy of the measurement result.

[0047] The ranging sensor is communicatively connected to the controller of the photovoltaic panel cleaning device, and the controller is communicatively connected to the first linear drive 4 and the second linear drive 5. The controller receives the distance between the cleaning mechanism 3 and the photovoltaic panel measured by multiple ranging sensors, and controls the movement of the first linear drive 4 and the second linear drive 5 according to the measured distance.

[0048] The present application realizes automatic adjustment of the angle and distance between the cleaning mechanism 3 and the photovoltaic panel, and responds quickly, thereby reducing the risk of the cleaning mechanism 3 colliding with the photovoltaic panel.

[0049] Specifically, the cleaning mechanism 3 is parallel to the photovoltaic panel, but the distance between the cleaning mechanism 3 and the photovoltaic panel is greater than the preset distance, and the first linear drive 4 and the second linear drive 5 drive the cleaning mechanism 3 at the same time to make the cleaning mechanism 3 move in the direction close to the photovoltaic panel until the distance between the cleaning mechanism 3 and the photovoltaic panel meets the preset distance; the cleaning mechanism 3 is parallel to the photovoltaic panel, but the distance between the cleaning mechanism 3 and the photovoltaic panel is less than the preset distance, and the first linear drive 4 and the second linear drive 5 drive the cleaning mechanism 3 at the same time to make the cleaning mechanism 3 move in the direction away from the photovoltaic panel until the distance between the cleaning mechanism 3 and the photovoltaic panel meets the preset distance; when the cleaning mechanism 3 is not parallel to the photovoltaic panel, the first linear drive 4 and the second linear drive 5 drive the cleaning mechanism 3 to move so that the cleaning mechanism 3 is parallel to the photovoltaic panel, and the distance between the cleaning mechanism 3 and the photovoltaic panel meets the preset distance.

[0050] The photovoltaic panel cleaning device disclosed in the present application measures the distance between the cleaning mechanism 3 and the photovoltaic panel in real time through a distance measuring sensor, and the controller sends instructions to the first linear drive 4 and the second linear drive 5 according to the measured distance, and the first linear drive 4 and the second linear drive 5 drive the cleaning mechanism 3 to move, so that the distance between the cleaning mechanism 3 and the photovoltaic panel meets the preset distance, and the cleaning mechanism 3 is parallel to the photovoltaic panel. The photovoltaic panel cleaning device disclosed in the present application can adjust the distance between the cleaning mechanism 3 and the photovoltaic panel in real time, so that the distance between the cleaning mechanism 3 and the photovoltaic panel meets the preset distance, and the cleaning mechanism 3 is parallel to the photovoltaic panel, which can effectively avoid the cleaning mechanism 34 of the photovoltaic panel cleaning device from colliding with the photovoltaic panel to prevent damage to the photovoltaic panel.
