Problems solved by technology

[0004] However, because the solar collector is placed outdoors, its working environment is harsh, especially in the northern region where the wind and sand are relatively large, and it is easy to form a dust layer on the surface of the vacuum tube, which seriously deteriorates the absorption of solar radiation energy by the collector. According to preliminary calculations and analysis, It will lead to a reduction in collector efficiency of about 5-20%.

Abstract

The automatic cleaning device for the accumulated dust on the surface of the solar vacuum tube heat accumulator comprises the track on the heat accumulator along its surface, sliding bar moving up and down on the said surface along the track, with soft wiping block on the slide bar connecting with the solar vacuum tube, and drive moving device moving up and down along the solar heat accumulator surface driven by the electric motor reacting with the said surface on the slide bar with good solution for the heating issue due to accumulated dust on the vacuum tube surface, with simple structure, safe, reliable and good dust eliminating effect.

Description

Technical field: [0001] The invention belongs to the field of solar light and heat utilization, and in particular relates to an automatic cleaning device for dust accumulated on the surface of a solar vacuum tube heat collector. Background technique: [0002] my country is rich in solar energy resources. The annual solar radiation received by the land is equivalent to 2.4 trillion tce, and the total solar radiation of two-thirds of the land area exceeds 0.6MJ / m 2 . Tibet, Qinghai, Xinjiang, Gansu, Ningxia, Inner Mongolia, Hebei, Henan and other places are in the zone of abundant solar energy resources. At present, my country has become a big country in solar thermal utilization. As the most mature technology, the most widely used and the fastest developing solar energy utilization technology, solar water heater has become another important choice for domestic hot water application after gas water heater and electric water heater. By the end of 2000, my country's solar wate...
