Abstract

Abstract: When the shearer is working, there is a temperature difference between the high power density mechanical transmission system of the machine arm, The thermoelectric effect can be used to convert this part of the thermal energy into electrical energy to power the arm sensors. Based on the energy harvesting technology and the actual working conditions of the shearer and the temperature distribution characteristics of the arm, designs a thermoelectric power generation system, Improved the structure of the thermoelectric power generation sheet and the heat dissipation device, using the LTC3108 energy harvesting management chip to manage the collected energy and provide reliable electrical energy for the sensor. Finally, the performance of the thermoelectric power generation system in practical application is studied through experiments, and compared with the theoretical calculation results, the feasibility of the thermoelectric power generation system is proved, this provides a new idea for solving the power supply problem of the shearer sensor.
