Description

Technical Field

[0001] The utility model relates to the technical field of robot charging, in particular to a charging device suitable for a hydropower station corridor inspection robot. Background Art

[0002] A hydropower station corridor refers to an artificial passage built at the water inlet and outlet of a hydropower station, which is used to maintain and repair the equipment and machinery of the hydropower station. Usually, a hydropower station corridor is built downstream of the dam of a hydropower station. It is an important passage connecting the water pipes and cables of the hydropower station. The construction of a hydropower station corridor needs to consider many factors, such as the geographical environment, water flow conditions, the layout of the hydropower station equipment, etc. Usually, the width of the corridor should be wide enough to accommodate the work of maintenance and repair personnel. At the same time, safety factors such as anti-slip and windproof should also be considered. At present, hydropower station corridor inspections usually use inspection robots for inspection operations. The inspection robots need to be charged when the power is low. When charging existing equipment, the inspection robots usually move to the interface to charge themselves, but it is easy for the inspection robot to be offset or improperly plugged in, resulting in the charging robot being unable to charge, and even easily causing damage to the equipment.

[0003] At present, robots are prone to deviation when approaching equipment for charging, which cannot assist the robot in centering and positioning. When the robot's battery is low, it cannot move and plug in for charging on its own, which easily leads to inaccurate plugging between the robot and the equipment, affecting the efficiency and practicality of the equipment charging the robot. Based on this, a charging device suitable for a hydropower station corridor inspection robot is provided, which uses a limit component to assist the robot to center itself near the charging component of the charging base, avoids the robot from deviating or tilting, and improves the efficiency and practicality of the charging base charging the robot.
