Cleaning device

Abstract

The invention discloses a cleaning device. The cleaning device comprises a shell, a power source, a walking unit, a guide suspension unit, a cleaning unit, a reversing unit, a sliding part, a magnetic element, a sensor and a control unit. A photovoltaic cleaning machine is suspended on a cleaned object through the guide suspension unit, and the guide suspension unit guides the walking direction of the cleaning device; the cleaning unit is arranged on the shell and is in contact with the surface of the cleaned object; the reversing unit comprises a support arranged on the shell; the sliding part is arranged on the support in a sliding manner, and extends to the position outside the support by the preset distance; the magnetic element is fixedly arranged on the sliding part and moves along with the sliding of the sliding part; the sensor is arranged at the predetermined position of the shell, and detects the motion of the magnetic element; and the control unit is connected with the sensor and drives the walking unit and the cleaning unit to move according to signals of the sensor. Through the scheme, false triggering of the cleaning device in the cleaning process can be effectively avoided, and the maintenance period is prolonged.

Description

technical field [0001] This patent belongs to the technical field of cleaning equipment, and relates to a cleaning device for automatically cleaning the surface of a flat plane, especially a photovoltaic module array. Background technique [0002] Solar photovoltaic power generation has been widely used in existing technologies and is a kind of clean energy. In the prior art, solar photovoltaic panels are usually used for solar power generation. When the surface of the solar cell panel is contaminated with dust or other sundries, the solar cell panel needs to be cleaned to improve power generation efficiency. [0003] Various cleaning devices for solar panel arrays have been recorded in the prior art, including an automatic cleaning vehicle, which can move left and right on the solar panel to realize automatic cleaning, which has the advantages of high efficiency and low cost. [0004] However, there are some problems in the sweeping vehicle in the prior art. Usually, its...

AI Technical Summary

Problems solved by technology

Usually its structure is relatively complex and the overall mass is large, which is easy to cause pressure on the solar photovoltaic panel, which is easy to cause damage to the solar panel

In addition, since reciprocating motion is required on the surface of the solar array to improve the cleaning effect, a reversing device is usually required in the sweeping vehicle, and the reversing device is prone to false triggering and damage due to the characteristics of its electronic components, resulting in Describe the working failure of the sweeper

Therefore, the cleaning vehicle in the prior art also has the problems of durability and applicability in actual use.
