Solar water heater allowing dust to be removed conveniently

Abstract

The invention discloses a solar water heater allowing dust to be removed conveniently. The solar water heater comprises a base, foldable wheels, a cleaning brush and screw holes, containing grooves are formed in the side face of the base, connecting rods are arranged inside the containing grooves, the foldable wheels are fixed to the connecting rods, the clearing brush is arranged in a sliding groove, an inner groove is formed in each first supporting rod, a clamping groove is formed in each inner groove, a second supporting rod is arranged inside each inner groove, a telescopic buckle is fixed to the surface of each second supporting rod, the screw holes are formed in the lower ends of the second supporting rods, and a thermal-insulation water tank is arranged above the base and connectedwith evacuated collector tubes. According to the solar water heater, the cleaning brush with sliding blocks is arranged on a support, meanwhile, bristle brushes on the cleaning brush sleeve the evacuated collector tubes, the cleaning brush can be driven by a motor to slide vertically on the evacuated collector tubes to clear off dust, the heating effect of the evacuated collector tubes can be enhanced, and accordingly the utilization rate of solar energy is increased.

Description

technical field [0001] The invention relates to the technical field of solar water heating devices, in particular to a solar water heater which is convenient for dust removal. Background technique [0002] Solar thermal utilization is an important field of renewable energy utilization, with mature technology and broad application prospects, and has obvious advantages in energy substitution, emission reduction, and safe energy use. At present, the most mature product of solar thermal utilization in my country is solar water heaters. Solar water heaters are heating devices that convert sunlight energy into heat energy, and heat water from low temperature to high temperature to meet the needs of hot water in people's life and production. Therefore, Now there are various solar water heaters on the market, but the solar water heaters on the market are exposed to the outside for a long time when they are in use, causing a large amount of dust to accumulate in the vacuum heat collec...

AI Technical Summary

Problems solved by technology

[0003] The object of the present invention is to provide a solar water heater that is convenient for dust removal, to solve the problem that the existing solar water heater proposed in the above background technology is exposed to the outside for a long time during use, causing a large amount of dust to accumulate in the vacuum heat collecting tube, so that the solar energy is irradiated in the vacuum. The heating effect on the heat collecting tube is poor, which reduces the utilization rate of solar energy, and the bulky solar water heater is not conducive to the problem of the user's transportation
