Auto-cleaning high-heat-production type flat plate solar collector

Abstract

The invention discloses an auto-cleaning high-heat-production type flat plate solar collector. The flat plate solar collector is characterized in that a transmission device arranged below a horizontal center shaft of a rack (7); the transmission device comprises motors (5), a rotary shaft (6), photosensitive sensors (10) and timing controllers (9); the motors are fixedly connected with the rotary shaft (6); the photosensitive sensors (10) are connected with the rotary shaft (6) through the timing controllers (9); the top end of the rack (7) is provided with cleaning devices (1); each cleaning device (1) comprises a hairbrush and spray nozzles, the spray nozzles communicate with a water storage tank (11) through a water pump, and the hairbrushes are mounted on supporting shafts; the two ends of each supporting shaft are provided with guide wheels (8), and the guide wheels (8) slide along guide rail grooves (2). Compared with manual cleaning, the auto-cleaning high-heat-production type flat plate solar collector is more convenient and easier to use and capable of saving time and labor and collecting more heat, and has an automatic protection function; when the flat plate solar collector is not in use, the transport and storage time can be shortened; the auto-cleaning and high-heat-production type flat plate solar collector is good in stationarity in the using process.

Description

technical field [0001] The invention belongs to the technical field of heat collectors, and in particular relates to an automatic cleaning and high heat-producing flat plate heat collector. Background technique [0002] In an environment that promotes the vigorous development of green energy, solar-powered trams are being developed and popularized. At present, improving the conversion rate of solar energy is the primary issue for the development and popularization of solar electric vehicles. The flat plate collector is made of all copper material, and the heat absorbing coating adopts blue coating and black chrome technology. Each square collector plate can replace 150kg of coal, which is quite 147 degrees of electricity, the amount of hot water collected per square meter is about 80kg and the temperature is above 50°C. It adopts double circulation, will not burst the tube, and is not afraid of hail. More than 30 years. [0003] There are also more and more developments an...

Problems solved by technology

In order to fully absorb the sunlight, these flat-plate collectors are generally placed at a certain height from the ground. Due to environmental factors, after a period of use, the surface of the flat-plate collectors will be covered with a thick layer of dust or Other foreign coverings that may fly, which will greatly affect the full absorption of solar rays by the flat-plate collector, thus greatly reducing the conversion efficiency of the flat-plate collector

The maintenance and cleaning of the existing flat-plate collectors are all done manually, but manual wiping of the flat-plate collectors is laborious and difficult to clean, thus affecting the power generation rate of the flat-plate collectors

The area of ​​the heat collector in the prior art is limited, and the electric energy converted by absorbing sunlight on one side of the flat plate heat collector is limited, and the power collection is relatively low, which cannot really meet the needs of vehicle driving
