Utility Model Content

[0006] The utility model aims to provide a photovoltaic power station operation and maintenance frame to solve the problem in the background art that the vertical rods will move and the photovoltaic panels cannot be effectively cleaned when the force applied by the fastening members is insufficient.

[0009] The cleaning device includes an installation box connected by screws, a water tank is arranged on the top of the installation box, a connecting pipe is arranged on one side of the water tank and passes through the transport box, a cylinder is arranged at the end of the transport box away from the connecting pipe, a piston plate is arranged at the piston end of the cylinder passing through the transport box, the piston plate is located inside the transport box, a water outlet pipe is arranged at the end of the transport box away from the cylinder, the other end of the water outlet pipe passes through the top of the installation box, a U-shaped frame is arranged on the front side of the installation box, a cleaning roller is connected to the inside of the U-shaped frame near the bottom through an axle rod, and a nozzle is arranged on the side wall of the U-shaped frame near the top.

[0010] In this embodiment, the motor drives the roller to rotate, and the rotation of the roller drives the guide block of the L-shaped plate to move along the guide groove of the fixed plate. The coordination between the guide and the guide groove can enhance the stability of the L-shaped plate during operation. The piston plate of the cylinder reciprocates in a straight line in the transport box. When the piston plate of the cylinder moves to the left, negative pressure appears in the transport box, so that the water in the water storage tank can be sucked into the transport box through the connecting pipe.

[0016] In this solution, the water inlet of the water tank cooperates with the box cover to facilitate the staff to open the box cover to transport water to the inside of the water tank. Since the nozzle runs through the U-shaped frame and the installation box, the water inside the installation box can be sprayed out by the nozzle.

[0017] In an implementation manner of the utility model, the pawl is installed on one side of the supporting shell, the pawl passes through the central axis and a spring is sleeved between the supporting shell and the pawl.

[0020] In this solution, the strength and stability of the support device can be increased by placing the crossbeam plate on the top of the tooth column. The support frame is at the opposite end of the crossbeam plate to ensure that it will not loosen or move during operation. The through holes and pins on the bottom plate can increase the stability of the support device.

[0021] In one implementation of the utility model, a photovoltaic panel is arranged on the top of the support frame, the shaft rods are located outside the support shell and are sleeved with bearing sleeves, and the support device is arranged in two groups.

[0022] In this solution, the bearing sleeve can provide axial support in the horizontal direction, reducing the friction between the shaft and the supporting shell. The supporting device is arranged in two groups to make the photovoltaic panel more stable.

[0025] Compared with the prior art, the beneficial effects of the utility model are:

[0026] 1. When the remote lever is rotated clockwise, the remote lever drives the shaft and gear to rotate, and the gear and the tooth column are meshed and transmitted, thereby raising the height of the tooth column. When the shaft stops rotating, the pawl locks the gear to prevent the gear from rotating unexpectedly and keep the shaft stable. When the remote lever is rotated counterclockwise, the pawl is pressed to lift up, so that the pawl is separated from the ratchet wheel, and the tooth column moves downward.

The adjustment bar of the connector is convenient for adjusting the height to be installed, and then the lateral distance between the cleaning roller and the photovoltaic panel can be adjusted, so that the position of the cleaning device can be adjusted as needed.

[0028] 3. The piston plate of the cylinder reciprocates in a straight line in the transport box. When the piston plate of the cylinder moves to the left, negative pressure appears in the transport box, so that the water in the water storage tank can be sucked into the transport box through the connecting pipe. When the piston plate of the cylinder moves to the right, the water in the transport box can be transported to the installation box through the outlet pipe, and finally sprayed out through the nozzle. The nozzle sprays water on the cleaning roller. At this time, cooperate with the driving device to make the cleaning roller clean the photovoltaic panel. BRIEF DESCRIPTION OF THE DRAWINGS
