Protective device of cleaning robot, photovoltaic power generation system and photovoltaic power station

Abstract

The protection device is used for a photovoltaic power generation system and comprises a swing rod mechanism, and the swing rod mechanism comprises a transmission shaft and a swing rod; the swing rod is hinged to the first photovoltaic module row or the second photovoltaic module row and has a storage state and a blocking state. The first end of the transmission shaft is connected with the swing rod and used for driving the swing rod to rotate to switch states. The second end of the transmission shaft is fixed at a preset position of the adjacent photovoltaic module row; when the installation angle difference between the first photovoltaic module row and the second photovoltaic module row does not exceed a preset value, the swing rod is kept in a storage state, and when the installation angle difference exceeds the preset value, the preset position transmits torque to the swing rod through the transmission shaft and drives the swing rod to rotate and switch to a blocking state. In the protection device, the swing rod is kept in the storage state when the installation angle difference of the first photovoltaic module row and the second photovoltaic module row does not exceed the preset value, normal work of the cleaning robot is guaranteed, the swing rod is switched to the blocking state when the installation angle difference exceeds the preset value, and falling of the cleaning robot is avoided. The invention further discloses a photovoltaic power generation system and a photovoltaic power station.

Description

technical field [0001] The invention relates to the technical field of photovoltaic power generation, and more particularly, to a protection device for cleaning robots, a photovoltaic power generation system, and a photovoltaic power station. Background technique [0002] Photovoltaic modules are used to convert solar energy into electrical energy and are the most important part of photovoltaic power generation systems. Photovoltaic modules are usually installed in the field or in the open air, and it is inevitable that impurities such as falling ash will cover them, which will affect the power generation efficiency. Therefore, the photovoltaic power generation system is generally equipped with cleaning robots to clean the photovoltaic modules. [0003] In the prior art, a plurality of photovoltaic modules are assembled into one body to form a photovoltaic module row. A bridge is set between adjacent photovoltaic module rows, which is convenient for the cleaning robot to cl...

AI Technical Summary

Problems solved by technology

However, when the adjacent photovoltaic module rows use their respective photovoltaic tracking brackets to adjust the installation angle, it is inevitable that there will be an angle deviation. If the deviation is too large, the bridge will be directly disconnected, causing the cleaning robot to fall from the gap between the adjacent photovoltaic module rows, endangering cleaning. robot safety

[0004] In addition, manual restoration is required after the bridge frame breaks, resulting in heavy maintenance workload and high cost in the later period
