Vacuum pipe cleaning device and solar water heater with same

Abstract

The invention discloses a vacuum pipe cleaning device and a solar water heater with the same. The cleaning device is provided with a plurality of semicircular grooves matched with the external diameter of a vacuum pipe of the water heater. The surface of each groove is wrapped with a sponge material. A water supply pipe is fixedly arranged above the grooves. Water outlets are formed in the positions, corresponding to the grooves, of the water supply pipe, and the water outlets are used for wetting the sponge materials. According to the solar water heater based on the vacuum pipe cleaning device, a water storage tank and the vacuum pipe of the water heater are connected and supported by a water heater support. The vacuum pipe cleaning device is installed on the vacuum pipe of the water heater, and the grooves make contact with the pipe wall. The two sides of the vacuum pipe cleaning device are fixed with guide rails, and the vacuum pipe cleaning device can be driven by a drive device to move back and forth in the axial direction of the vacuum pipe of the water heater. The vacuum pipe cleaning device and the solar water heater with the same have the beneficial effects that the cleaning device is mounted to the solar water heater so as to clean the solar water heater, manual cleaning is replaced, danger caused by manual cleaning is avoided, and the heating efficiency is ensured.

Description

technical field [0001] The patent of the invention belongs to the field of energy saving and environmental protection, and specifically relates to a vacuum tube cleaning device and a solar water heater equipped with the device. Background technique [0002] Nowadays, many families use solar water heaters to provide hot water for bathing and other purposes. Solar water heaters use sunlight to heat the water in the vacuum tube and store the hot water in a water storage tank with thermal insulation function for use. Solar water heaters use sunlight, a natural resource, to heat water without requiring a large amount of energy such as electricity , so solar water heater is a very energy-saving and environmentally friendly equipment. [0003] However, since solar water heaters are generally placed on the roof, after a period of use, thick dirt will accumulate on the vacuum tube and it is difficult to remove it by air flow and rainwater. The solar energy obtained is reduced, whic...

AI Technical Summary

Problems solved by technology

[0004] The current cleaning devices for solar water heaters are basically powered by additional power, and a sprinkler is installed above the vacuum tube to spray water to clean the vacuum tube, which consumes additional power and consumes a lot of water for nozzle cleaning.
