Cleaning mechanism and heliostat system

Abstract

The invention relates to the technical field of solar energy utilization, and particularly discloses a cleaning mechanism and a heliostat system. The cleaning mechanism comprises a supporting beam, cleaning assemblies, elastic pieces, a water supplying assembly and a driving assembly, wherein a water supplying flow channel is arranged in the supporting beam in the length direction; the cleaning assemblies are in a long strip shape, the cleaning assemblies are arranged on one side of the supporting beam at intervals in the length direction of the supporting beam, water spraying flow channels are arranged in the cleaning assemblies, the water spraying openings of the water spraying flow channels are located on the sides, far away from the supporting beam, of the cleaning assemblies, and thewater spraying flow channels communicate with the water supplying flow channel; one ends of the elastic pieces are connected with the supporting beam, and the other ends of the elastic pieces are connected with the cleaning assemblies; the water supplying assembly communicate with the water supplying flow channel, and is used for supplying clean water to the water supplying flow channel; the driving assembly is connected with the supporting beam and is used for driving the supporting beam to rotate or horizontally move. The heliostat system comprises the cleaning mechanism. According to the cleaning mechanism and the heliostat system, the structure of the cleaning mechanism is simplified, the size and the cost of the cleaning mechanism are reduced, and the flexibility and convenience of heliostat cleaning are improved.

Description

technical field [0001] The invention relates to the technical field of solar energy utilization, in particular to a cleaning mechanism and a heliostat system. Background technique [0002] With the rapid increase in energy demand for social development, solar energy, as a clean and renewable energy, has been more and more widely used. Tower solar power generation is a system that uses a large number of heliostats to gather sunlight to the heat collector installed in the heat collection tower, heats the working fluid in the heat collector to generate steam, and drives the steam turbine generator to generate electricity. Among them, the main function of the heliostat is to gather sunlight to the heat collector. Therefore, the cleanliness of the mirror surface of the heliostat will affect the reflectivity of the mirror surface, thereby affecting the incident energy of the heat collector. Since the heliostat is located in an outdoor environment, it is greatly affected by the ex...

Problems solved by technology

[0004] The heliostat mirror surface cleaning system provided by the prior art has a complex structure and a large volume, and the heliostat cleaning system is loaded on a traveling device. When cleaning the heliostat, it is necessary to install the cleaning system on site and run the traveling device Each heliostat in the heliostat field is cleaned sequentially, resulting in low cleaning efficiency and high cleaning costs, and it is difficult to clean individual heliostats in real time according to the needs of each heliostat, flexible cleaning less flexible
