Solar water heater heat collecting pipe cleaning device

Abstract

The invention provides a solar water heater heat collecting pipe cleaning device, and relates to the field of solar energy. The solar water heater heat collecting pipe cleaning device comprises a fixed cover, expansion plates are fixedly connected to the lower end of the fixed cover, expansion rods are hinged to the sides, close to each other, of the expansion plates, push-pull mandrels are hinged to the ends, close to each other, of the expansion rods, digging plates are hinged to the lower ends of the expansion plates, traction rods are hinged to the sides, close to each other, of the digging plates, traction sliding blocks are hinged to the ends, away from the digging plates, of the traction rods and slidably connected with the push-pull mandrels, and a permeable ring is fixedly connected to the upper end of the fixed cover. According to the solar water heater heat collecting pipe cleaning device, the expansion rods expand earlier than the digging plates, so that scale at the bottom of a pipe can be fully surrounded, the bottom ends of the digging plates are bent and contracted, the scale deposited at the bottom of the heat collecting pipe is dug out of the pipe, the problem that the spherical end of the bottom end of the heat collecting pipe cannot be thoroughly cleaned is solved, and the effect of digging the bottom of the heat collecting pipe to clean the scale is achieved.

Description

technical field [0001] The invention relates to the field of solar energy, in particular to a device for cleaning heat collecting tubes of solar water heaters. Background technique [0002] The heat collecting tube is also called the heat collecting plate, which is the name of the solar energy industry for the outdoor heat collecting parts of the solar water heater. A solar thermal collector with good performance is one of the key equipment of solar air conditioners. Its main function is to collect the heat energy in the sunlight and transfer it to the water tank through the connecting pipeline to heat the cold water in the water tank. [0003] When the heat collecting tube heats cold water, a large amount of scale will be generated. The accumulation of scale and condensation on the heat collecting tube will weaken the heating effect and reduce the water capacity. When cleaning the heat collecting tube, chemical reaction is usually used to remove it. However, since the heat ...
