Description

Technical Field

[0001] The utility model belongs to the technical field of pollution-free water washing devices for solar panels, and in particular relates to a pollution-free water washing device for solar panels. Background Art

[0002] The pollution-free water washing device for solar panels is a device for cleaning solar panels. The device consists of a cleaning water tank, a brush head and a driving component. Workers place the brush head on the surface of the panel through a handle. The driving component drives the brush head to rotate, and the brush head also sprays water to achieve water washing of the panel. This water washing method is more environmentally friendly and pollution-free than the traditional method using large machinery, and is easy to clean.

[0003] The existing pollution-free water washing device for solar panels operates the brush head position by a handle to achieve water washing of the solar panel, but has the following defects:

[0004] (1) Since solar panels are directly exposed to the outside world, various difficult-to-clean debris and large hard debris are easily present on their outer surfaces. When using a pollution-free water washing device for solar panels to clean them, such debris may get stuck on the brush head and easily hinder the rotation of the brush head. If the work cannot be stopped in time, it is very easy to cause the motor component of the device to be overloaded and damaged. For this reason, we propose a pollution-free water washing device for solar panels. Utility Model Content

[0005] The purpose of the utility model is to provide a pollution-free water washing device for solar panels, so as to solve the problem that when the water washing device proposed in the above background technology is in use, larger debris gets stuck on the brush head and easily hinders the rotation of the brush head. At this time, if the work cannot be stopped in time, it is very easy to cause the motor component part of the device to be overloaded and damaged.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a pollution-free water washing device for solar panels, comprising a frame, on which two motor assemblies are symmetrically installed, a handle is connected to the center of the frame, a brush head is arranged at the bottom of the motor assembly, an end column is installed at the output end of the motor assembly, the outer walls of the end column are respectively provided with a spring and a movable sleeve, a base is arranged at the bottom of the movable sleeve, the base is fixed on the brush head, a synchronization groove is opened on the inner wall of the movable sleeve, a synchronization block is arranged on the inner side of the synchronization groove, and the synchronization block is fixed on the side wall of the end column.

[0007] Preferably, the bottom end of the end column extends to the interior of the base, an anti-slip groove with a circular cross-section is provided inside the base, an anti-slip block is provided inside the anti-slip groove, and the anti-slip block is fixed on the outer wall of the end column.

[0008] Preferably, there are two anti-dropping blocks, and the two anti-dropping blocks are symmetrical about the central axis of the end column.

[0009] Preferably, adjacent surfaces of the movable sleeve and the base are provided with inclined surfaces with the same slope, and the diameters of the movable sleeve and the base are equal.

[0010] Preferably, the longitudinal section of the end column is a T-shaped structure.

[0011] Preferably, the cross-sections of the end column, the movable sleeve and the base are all circular structures, and the central axes of the end column, the movable sleeve and the base coincide with each other.

[0012] Preferably, a spherical groove is formed on the bottom surface of the end column, and a ball is embedded in the spherical groove.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] (1) Through the designed end column, spring, movable sleeve, base and synchronous block, the movable sleeve cooperates with the synchronous block and the synchronous groove to ensure that it can rotate synchronously while sliding on the end column. The end column equipped with the movable sleeve is connected to the output shaft of the motor assembly, and the base is fixed on the brush head. The spring exerts elastic squeezing action on the movable sleeve so that the inclined surfaces of the movable sleeve and the base fit tightly. During rotation, a torque is generated between the inclined surfaces to drive the base to rotate, and the surface of the solar panel is washed with water through the brush head. When larger particles of debris on the surface of the solar panel are stuck in the brush head and hinder its rotation, the torque force between the base and the movable sleeve increases. When its force is greater than the spring, the movable sleeve is pushed up, thereby stopping the power transmission in time, so that the motor assembly is separated from the brush head in time, effectively avoiding damage to the motor assembly caused by excessive load due to obstruction of the brush head. Through the designed anti-slip groove and anti-slip block, one end of the end column is rotatably connected to the base to avoid the brush head from falling off the device of the utility model. Through the designed ball bearing, the wear between the end face of the end column and the base is reduced. BRIEF DESCRIPTION OF THE DRAWINGS
