Design and research of hydraulic support self-power supply system based on hydraulic motor power generation

At present, the underground coal mine power supply environment is very complicated, electronic equipment is constantly put into use, and the safety of coal mine power supply is becoming increasingly serious. In order to realize the lightweight power supply of low-power electrical appliances for the hydraulic bracket in the underground coal mine, and improve the underground power supply environment, a set of hydraulic bracket self-power supply system has been designed. The basic design principle of the system, the design of each module are introduced in detail and the field industrial test is carried out. Through the data analysis of the energy loss of the system, the input and output parameters of the battery, as well as the thermal runaway analysis of the battery, it is determined that the system can achieve a stable power supply to the electrical appliances; the system has a high degree of integration, strong maintainability, and provides a safety guarantee for the power supply of low-power electrical appliances of the hydraulic bracket in the underground mine.
