Problems solved by technology

Taking Northwest China as an example, the temperature difference between morning and evening is large, and the temperature in winter is low. After automatic cleaning, it is easy to freeze on the solar panels, which will affect the normal operation of the system.
At the same time, considering the characteristics of the butterfly concentrator itself (the surface of the disc has a certain curvature, and its radius is generally greater than 1m), the automatic cleaning device on the surface of the butterfly solar concentrator is subject to certain restrictions in the design process
Visible, prior art method and device are not suitable for the self-cleaning of butterfly solar concentrator surface

Embodiment Construction

[0012] Such as figure 1 As shown, the present invention The automatic cleaning device on the surface of the dish solar concentrator has a motor 1, an input shaft 2, a first gear 3, a second gear 4 and an output shaft 5, a travel switch 7, a chute 9 and a temperature sensor 10 are all installed on the concentrator. On the optical device 6, the cleaning brush 8 is composed of two cleaning brushes installed at an angle, one end of which is connected to the output shaft 5 of the rotary center, and the other end is connected to the chute 9, and the motor 1 can drive the transmission mechanism to make the cleaning brush 8 move along The chute 9 makes intermittent reciprocating motions on the surface of the concentrator 6 .

[0013] Such as figure 1 , figure 2 as shown, When the cleaning brush 8 touches the travel switch 7 at the bottom of the concentrator 6, the transmission part stops working; the sensor 10 measures the external temperature as a criterion for the start of...

Abstract

The invention relates to an automatic cleaning device for the surface of a disc type solar condenser. The automatic cleaning device is provided with a motor (1), and is characterized in that an input shaft (2), a first gear (3), a second gear (4), an output shaft (5), a travel switch (7), a sliding groove (9) and a temperature sensor (10) are all arranged on a condenser (6); a cleaning brush (8) is formed by two cleaning brushes which are arranged in an angle; one end of the cleaning brush (8) is connected with the output shaft (5) of a rotating center, and the other end of the cleaning brush (8) is connected with the sliding groove (9); the cleaning brush (8) is driven to make intermittent back and forth movement on the surface of the condenser (6) along the sliding groove (9) by a transmission mechanism driven by the motor (1).

Description

technical field [0001] The invention relates to the technical field of solar photothermal power generation, and is an automatic cleaning device suitable for the surface of an integral butterfly solar concentrator. Background technique [0002] Since the solar automatic tracking device is placed outdoors for a long time, the surface is easily stained with dust and other dirt. Over time, the utilization rate of solar energy will decrease significantly. In addition, a large amount of snow covering the surface of the concentrator in winter not only affects the utilization rate of solar energy, but also has a certain impact on the stability of the entire equipment. If manual cleaning is adopted, it is troublesome and unsafe. [0003] In the prior art, solar automatic cleaning devices are generally applied to solar panels. Its purpose is to remove dust or snow on the surface of the solar panel to ensure the conversion efficiency of the solar module, thereby ensuring the power ge...
