Dust removal type solar water heater with anti-freezing function

Abstract

The invention relates to a dust removal type solar water heater with the anti-freezing function. The water heater comprises a bottom plate, a supporting plate, a supporting column, a water tank, a connecting pipe and multiple heat collecting devices. Each heat collecting device comprises a heat collecting pipe and two first bearings. An anti-freezing mechanism and multiple dust removal mechanismsare further included. Each dust removal mechanism comprises a cleaning plate and multiple connecting assemblies. The anti-freezing mechanism comprises a driving assembly, a stirring assembly and multiple first gears. According to the dust removal type solar water heater with the anti-freezing function, through the dust removal mechanisms, the dust removal function is achieved, dust is prevented from covering the heat collecting pipes, the heat collecting effect of the heat collecting pipes is not affected, the anti-freezing mechanism is arranged, water in the heat collecting pipes and water inthe water tank can be shaken, the anti-freezing function of the heat collecting pipes and the water tank can be achieved, the phenomenon that the water is iced, and equipment is damaged is avoided, and the equipment reliability is improved.

Description

technical field [0001] The invention relates to the field of solar water heaters, in particular to a dust-removing solar water heater with antifreeze function. Background technique [0002] A solar water heater is a heating device that converts sunlight energy into heat energy, and heats water from low temperature to high temperature, so as to meet the hot water use in people's life and production. Solar water heaters are divided into vacuum tube solar water heaters and flat plate solar water heaters according to their structure. The vacuum tube solar water heaters are the main ones, accounting for 95% of the domestic market share. Vacuum tube household solar water heaters are composed of heat collecting tubes, water storage tanks and brackets and other related parts. The conversion of solar energy into heat mainly depends on vacuum heat collecting tubes. And get the hot water you need. [0003] Existing solar water heaters are usually installed in the open air, resulting ...

AI Technical Summary

Problems solved by technology

[0003] Existing solar water heaters are usually installed in the open air, resulting in the exposure of the heat collecting tubes, which are easily covered by dust, thereby affecting the heat absorption effect of the heat collecting tubes. Not only that, but when the existing solar water heaters work in cold winter, due to the low temperature, resulting in The water remaining in the heat collecting tube and the water tank is easy to freeze, making the equipment unable to work normally, thus increasing the chance of equipment damage and reducing the practicability of the existing solar water heater
