Hydraulic charging device for underground coal mine inspection robot

Abstract

The invention provides a hydraulic charging device for an underground coal mine inspection robot. The hydraulic charging device comprises a walking track arranged in an underground coal mine roadway,an inspection robot which is installed on the walking track and can move along the walking track in a reciprocating mode, and a charging assembly which supplies electric energy to the inspection robot. The charging assembly comprises a power generation device arranged on an inspection robot body and a power assembly arranged in the underground coal mine roadway and used for providing kinetic energy for the power generation device. The power generation device comprises an explosion-proof power generation motor and an impeller arranged at the tail end of the rotating shaft of the explosion-proofpower generation motor. The power assembly comprises a submersible pump and a water outgoing pipe connected with the water outlet of the submersible pump; and the potential energy of water flowing out of the water outgoing pipe is enough to push the impeller to rotate, so that the explosion-proof motor works. The hydraulic kinetic energy is converted into the electric energy through the explosion-proof power generation device, and the electric energy is used for charging the storage battery of the robot, so that the charging of the coal mine underground inspection robot is realized.

Description

technical field [0001] The invention relates to the field of coal mine equipment, in particular to a hydraulic charging device for a coal mine underground inspection robot. Background technique [0002] With the continuous advancement of automation and intelligent technology, in order to reduce the work intensity and work risk of manual inspection in coal mines, and improve the quality and efficiency of inspections, coal mine inspection robots are popularized and applied in inspections in underground coal mines. The power of the coal mine inspection robot is usually provided by its own battery. When the battery pack is low, the inspection robot needs to be charged to supplement the energy. In view of the safety and explosion-proof requirements of coal mines, the main charging methods are as follows: ground charging, underground safe environment charging, wireless charging, and explosion-proof interface charging. , intelligent, fast charging application requirements.

AI Technical Summary

Problems solved by technology

In view of the safety and explosion-proof requirements of coal mines, the main charging methods are as follows: ground charging, underground safe environment charging, wireless charging, and explosion-proof interface charging. , intelligent, fast charging application requirements

Specifically, ground charging has lower explosion-proof requirements for charging devices and charging interfaces, but the inspection robot needs to return to the ground from underground to charge, which consumes extra energy of the battery pack and takes a long time to go back and forth; charging in a safe environment underground requires the construction of additional charging tunnels room, high cost, high difficulty, and low cost performance; wireless charging power is small, charging is slow, and cannot meet the needs of fast charging; charging with explosion-proof interfaces has high requirements for explosion-proof interfaces and docking controls, and additionally designed complex driving devices and locking mechanisms are required. It is difficult to guarantee the continuous effectiveness of the explosion-proof interface
