Heat-collecting pipe support of groove-type solar-energy heat collector

Abstract

The invention relates to a heat-collecting pipe support of a groove-type solar-energy heat collector. The heat-collecting pipe support comprises support bodies, wherein heat-collecting pipe clamping mechanisms are arranged at the top parts of the support bodies, the support bodies from the middle support body to the support bodies towards two ends in a row of support bodies of a same heat-collecting pipe sequentially raises and are clamped by the clamping mechanisms, and elastic parts capable of elastically deforming in the axial direction of the heat-collecting pipe are connected to the bottom parts of the support bodies. The invention has the beneficial effects that when the heat-collecting pipe expands when heated and contracts when cooled, the expansion and contraction forces of the heat-collecting pipe can be buffered by plate springs, so that the heat-collecting pipe can be effectively prevented from being damaged, force balance is kept to a certain extent, and the stability of heat collection is guaranteed.

Description

technical field [0001] The invention relates to a heat collecting pipe support of a trough solar heat collector. Background technique [0002] Solar energy is one of the most concerned sources of energy in the field of new energy. The trough solar collector is a device that absorbs solar radiation and transfers the generated heat to the heat transfer medium. There are many trough solar collectors on the market, but the existing technology of the trough solar collector There are still many problems. 1. The thermal expansion and contraction of the heat collection tube of the trough solar collector. When the heat collection tube is heated to a higher temperature, the heat collection tube will elongate in the axial direction, but this elongation will The stainless steel tube in the heat collecting tube is bent downward, and once it touches the outer glass tube, the heat collecting tube will be damaged, and the bending of the heat collecting tube makes the heat collecting tube...

The trough solar collector is a device that absorbs solar radiation and transfers the generated heat to the heat transfer medium. There are many trough solar collectors on the market, but the existing technology of the trough solar collector There are still many problems. 1. The thermal expansion and contraction of the heat collection tube of the trough solar collector. When the heat collection tube is heated to a higher temperature, the heat collection tube will elongate in the axial direction, but this elongation will The stainless steel tube in the heat collecting tube is bent downward, and once it touches the outer glass tube, the heat collecting tube will be damaged, and the bending of the heat collecting tube makes the heat collecting tube not always keep at the focal point, so that the temperature of the heat collector Unstable; 2. The adjustment of the focal length of the collector. The general collector tube is fixed and cannot be fine-tuned according to the actual situation, so the adaptability is not high
