Description

Technical Field

[0001] The utility model relates to the technical field of photovoltaic cleaning robots, in particular to a transverse moving photovoltaic cleaning robot. Background Technique

[0002] The traditional cleaning method for solar photovoltaic modules is to clean each piece manually with a water gun or a brush. The method of manual wiping can indeed effectively solve the problem of mirror surface cleaning. However, this cleaning method has a large labor intensity, high cost, and is very inconvenient to clean. It cannot be cleaned frequently, and the management difficulty is large. Different operators have different strengths and different pressures on the modules, which will cause the modules to deform too much, resulting in hidden cracks in the glass panels of the photovoltaic modules. Therefore, at present, most photovoltaic module cleaning equipment is used for cleaning, which solves the defects of manual cleaning.

[0003] However, the existing photovoltaic module cleaning equipment can only achieve single string cleaning. People need to follow the machine and cannot achieve automatic cross-string cleaning. It requires manual handling of equipment, which is time-consuming and laborious, and the cleaning efficiency is low. Therefore, we provide a transverse moving photovoltaic cleaning robot. Content of the Utility Model

[0004] The purpose of the utility model is to provide a transverse moving photovoltaic cleaning robot, which can automatically change the moving direction, achieve cross-string cleaning, does not require manual handling of equipment, and has high cleaning efficiency.

[0005] To achieve the above purpose, the utility model provides the following technical solution: A transverse moving photovoltaic cleaning robot, including a frame, the side cross-section of the frame is n-shaped, a plurality of photovoltaic panels are fixedly installed on the upper surface of the frame, cleaning brushes and cleaning rubber strips are installed at the bottom of the front and rear sides of the frame, the cleaning rubber strip is arranged on the side close to the cleaning brush facing the inside of the frame, a moving component is rotatably installed at both ends inside the frame, a lifting component is installed between the two moving components inside the frame, there are two lifting components, and they are symmetrically arranged with the center of the frame as the center, and a control box and a storage battery are fixedly installed between the two lifting components inside the frame.

[0006] The photovoltaic panel is used to charge the storage battery. The moving component drives the photovoltaic cleaning robot to move. The cleaning brush cleans the photovoltaic module, and the cleaning rubber strip performs secondary cleaning. When it is necessary to change the moving direction, the lifting component is started to drive the photovoltaic cleaning robot to rise, so that the moving component is away from the upper surface of the photovoltaic module, and then the moving component is rotated. When the moving component rotates to the required angle, the lifting component drives the photovoltaic cleaning robot to descend, so that the moving component is reattached to the surface of the photovoltaic module, thereby changing the moving direction of the photovoltaic cleaning robot.

[0007] Preferably, the moving component includes a support frame, gears, a crawler belt, and a corner reduction motor. The support frame is rotatably connected to the inner wall of the top of the frame. Two gears are provided and are respectively rotatably installed at both ends of the support frame.

[0008] Preferably, limiting rods are fixedly installed on the outer sides of both ends of the frame where the moving component is located. A contact sensor is fixedly installed on the side of the support frame away from the limiting rod. The limiting rods are used to limit the support frame so that the support frame can only rotate within a specified angle.

[0009] Preferably, a first cylinder is fixedly installed inside the frame. A sliding plate is slidably installed on the upper surface of the first cylinder. Both ends of the sliding plate are fixedly installed with telescopic rods, and the output ends of the telescopic rods are respectively rotatably connected to the sides of the corresponding support frames. The output end of the first cylinder is fixedly connected to the sliding plate. The first cylinder controls the sliding plate to slide back and forth between the two support frames, so that the telescopic rods at both ends alternately expand and contract, and the two support frames rotate synchronously.

[0010] Preferably, the first cylinder and the sliding plate are parallel to each other, the sliding plate and the cleaning rubber strip are parallel to each other, and the telescopic rod and the contact sensor are located on the same horizontal plane. The contact sensor performs secondary limiting on the support frame. When the support frame rotates and contacts the limiting rod, the contact sensor contacts the telescopic rod and controls the first cylinder to stop working to avoid damage to the limiting rod.

[0011] Preferably, the lifting component includes a support plate. A scissor lift mechanism is fixedly connected to the top of the support plate, and the other end of the scissor lift mechanism is fixedly connected to a driving mechanism. The scissor lift mechanism is a traditional lift mechanism. Guide sleeves are fixedly installed on both sides of the scissor lift mechanism, and guide columns are fixedly installed at the positions corresponding to the guide sleeves on the top of the support plate. The scissor lift mechanism controls the lifting of the support plate, and at the same time, the guide columns slide in the guide sleeves to control the lifting of the photovoltaic cleaning robot.

A plurality of floating link rods are equidistantly installed on the side of the installation strip facing the inside of the frame. A torsion spring is sleeved on the floating link rod. The end of the floating link rod away from the installation strip is rotatably connected to the bottom of the cleaning rubber strip. Through the cooperation of the floating link rod and the torsion spring, the cleaning rubber strip always fits the surface of the photovoltaic module due to the elastic force of the torsion spring during operation.

[0015] Compared with the prior art, the present utility model adopts the above technical solutions and has the following technical effects:
