A low-temperature environment sunlight heat extraction power generation device

Abstract

The invention relates to a low-temperature environment sunlight heat extraction power generation device, relates to a power supply technology of an electric power online monitoring device, and aims tosolve the problem that an existing heat extraction power generation device is limited in application range and low in heat absorption efficiency. A heat collecting pipe of the device is a double-layer transparent tube, the double-layer transparent tube is vacuumized, the top of the heat collecting pipe is open, and the bottom is closed; power generation pieces are thermoelectric power generationpieces; the power generation pieces are arranged in a middle part of the heat collecting pipe; the power generation pieces are clamped between a hot end radiator and a cold end radiator; the bottom ofa cold end thermal isolation piece is fixed to the cold end radiator, the top of the cold end thermal isolation piece extends to the open end of the heat collecting pipe, and two side walls of the cold end thermal isolation piece are in full contact with an inner wall of the heat collecting pipe; and the top of a hot end thermal isolation piece is fixed to the hot end radiator, the bottom of thehot end thermal isolation piece extends towards the bottom of the heat collecting pipe and keeps a certain distance from the bottom of the heat collecting pipe, and two side walls of the hot end thermal isolation piece are in full contact with the inner wall of the heat collecting pipe. The beneficial effects are that the range of application is wide, and the heat absorption efficiency is high.

Description

technical field [0001] The invention relates to a power supply technology of an online power monitoring device. Background technique [0002] Power on-line monitoring devices are often installed on iron towers of transmission lines in the field; it is difficult for these iron towers to provide low-voltage power suitable for monitoring equipment in the wild. Usually wind power generation, solar panels, etc. are mainly used to provide the required power, but because wind power generators need rotating mechanical parts, bearings, generators and other components are affected by low temperature in low temperature environments, and their performance in terms of lubrication and wear resistance deteriorates seriously, making it difficult Reliable operation. However, solar power generation is affected by natural environmental factors such as low temperature, snow cover, and ice cover. On the one hand, the lifespan of semiconductor materials is reduced, and on the other hand, solar p...
