Description

Technical Field

[0001] The utility model belongs to the technical field of water heaters, and in particular relates to a solar water heater cleaning and bird-proofing device in the Loess Plateau area. Background Art

[0002] At present, solar water heaters are devices that use sunlight to heat water. Solar water heaters are divided into collector tube solar water heaters and flat plate solar water heaters. Collector tube solar water heaters occupy 95% of the domestic market share. Collector tube household solar water heaters are composed of collector tubes, storage tanks, brackets and other related parts. The conversion of solar energy into heat energy mainly relies on vacuum collector tubes. The principle of hot water floating and cold water sinking is used to make water microcirculate to achieve the required hot water.

[0003] Atmospheric precipitation is scarce in the Loess Plateau of China, and precipitation is concentrated in June-August. There is a serious lack of precipitation in winter and spring, and the air humidity is low, which produces a lot of dust. As a result, the vacuum tubes of solar water heaters will be attached with a lot of dust after long-term use. Especially in plateau areas, wind and sand phenomena often occur, which is more likely to cause a lot of dust accumulation, and birds often pass by and poop on the heat collecting tubes, which affects the heat collection of the heat collecting tubes, that is, the heat collecting efficiency is low. Therefore, a cleaning device for the heat collecting tube came into being. However, there are some defects in the cleaning device in the prior art. For example, the application number CN201921073011.7 is a solar water heater cleaning machine. Although the dust on the heat collecting tube can be cleaned by water, cleaning agent and sponge, the large dust particles on the heat collecting tube and the hard sticky objects such as bird droppings are forcibly cleaned by reciprocating cleaning, which will damage the heat collecting tube and will not be cleaned properly.

[0004] In view of this, the utility model proposes an automatic cleaning and bird-proofing device for solar water heaters in plateau areas, which can quickly clean dust of different particle sizes and sticky objects such as bird droppings, ensure that they are clean, and prevent birds from stopping to defecate. Summary of the invention

[0013] 1. By setting up a cleaning mechanism, a spraying mechanism and a driving mechanism, when cleaning the heat collecting tube, the driving motor, the electric telescopic rod and the high-pressure spray gun are started at the same time. When the screw drives the mounting frame to move, the high-pressure spray gun sprays the heat collecting tube with high pressure through the nozzle. The dust and bird droppings on the heat collecting tube can be cleaned first. The reciprocating motion of the electric telescopic rod causes the rack to pull the sliding plate to reciprocate, that is, the sponge brush performs a secondary cleaning on the heat collecting tube after high-pressure spraying, and cleans the water stains on the heat collecting tube, so that quick and thorough cleaning can be achieved;
