[0001] The invention relates to the technical field of heliostat cleaning, and in particular to a straddling heliostat cleaning vehicle. Background Art

[0002] The straddle-type heliostat cleaning vehicle is an efficient cleaning device designed specifically for large-scale CSP power stations. It is used to clean dirt and dust on the surface of heliostats to ensure the optimal performance of the photovoltaic system. The cleaning vehicle can automatically and accurately move along the curved surface of the heliostat. It is equipped with a high-pressure water jet system and an intelligent water recycling function, which not only saves water resources but also maximizes the cleaning efficiency. It can quickly and accurately clean dirt and dust on the surface of the heliostat to ensure the optimal performance of the photovoltaic system. This cleaning vehicle can work stably under a variety of weather conditions, effectively improve the cleaning efficiency, and at the same time improve the energy efficiency of CSP. Its use significantly reduces long-term operating costs and provides strong support for the effective use of renewable energy. This innovative cleaning solution helps to reduce long-term operating costs, improve the overall energy efficiency of CSP systems, and provide strong technical support for the use of renewable energy.

[0003] After searching, the Chinese patent number CN217857615U discloses a straddling heliostat cleaning vehicle, including a cleaning vehicle frame, a working box is fixedly connected to the top of the cleaning vehicle frame, a water tank is fixedly connected to the left side of the top of the inner cavity of the working box, a cleaning liquid tank is fixedly connected to the right side of the top of the inner cavity of the working box, a first conveying mechanism is fixedly installed on the left side of the bottom of the inner cavity of the working box, and a water suction pipe is fixedly connected to the top of the first conveying mechanism. This device can clean the surface of the heliostat by adding a water flow cleaning structure, thereby ensuring the cleanliness of the heliostat and facilitating better work of the heliostat. By adding a cleaning liquid spraying structure and a rotating wiping cleaning structure, it is convenient to clean the heliostat twice, thereby achieving the purpose of the staff, solving the troubles of the staff, and meeting the needs of the staff. Compared with the prior art, the Chinese patent number CN217857615U solves the problem that the existing heliostat cleaning vehicle cannot meet the needs of users during use due to the single cleaning function, which not only reduces the use efficiency of the cleaning vehicle, but also brings troubles to the staff.

[0004] However, in actual use of the above device, dust often adheres to the surface of the heliostat during the cleaning process, which easily causes the dust to be blown out during cleaning. In addition, the heliostat generally has a certain inclination during the cleaning process. If the inclination angle is large, the flushing water will flow down quickly before scrubbing, which not only affects the scrubbing effect, but also causes a waste of water resources. Therefore, a straddling heliostat cleaning vehicle is proposed. Summary of the invention

A cleaning mechanism is provided at the rear end of the cleaning and dust removal mechanism, which can drive the cleaning roller 17 to rotate and clean the surface of the heliostat.

[0035] A turbofan 21 is arranged inside the cleaning and dust removal mechanism. When the mechanism is working, the turbofan 21 and the cleaning brush 22 rotate simultaneously.
