Description

Multi-mode contact net insulator belt cleaning device Technical Field The invention belongs to the technical field of contact net cleaning, and particularly relates to a multi-mode contact net insulator cleaning device. Background The contact net insulator is a core component of a rail transit power supply system, is used as a key device for supporting contact suspension and realizing electric insulation, and the performance of the contact net insulator directly determines the safety and reliability of the whole power supply network. In the running process of the high-speed train, the insulator needs to bear mechanical load, electrical stress and complex environmental corrosion for a long time, and the surface cleanliness and the insulating property of the insulator form double guarantees for stable running of a power supply system. The insulator is vital to the contact network power supply system, can effectively isolate the high-voltage live body from the grounding part, ensures the safe transmission of voltage, can bear various external forces to ensure the stability of the bow gateway system, and has weather resistance and environmental corrosion resistance. But the insulation performance of the filth produced by industrial pollution and the like is reduced, pollution flashover accidents are easy to occur when the filth is wet, and chain reactions such as power supply interruption, equipment damage and the like are caused. The systematic cleaning and maintenance are key to solving the pollution problem, and the high-pressure water jet and special cleaning agent are adopted to cooperatively operate, so that the pollution layer can be precisely removed, the hydrophobic performance can be recovered, the pollution flashover resistance of the power supply system can be obviously enhanced, the service life of the insulator can be prolonged, and the replacement cost can be reduced. The intelligent cleaning period model is built to realize predictive maintenance, so that the power failure rate caused by insulator pollution can be controlled at an extremely low level, and reliable power guarantee is provided for rail traffic operation. With the continuous progress of insulator cleaning technology, various modes such as high-pressure water flushing, laser cleaning, mechanical cleaning devices, dry ice cleaning and the like are gradually perfected, and good cleaning effects are shown in specific scenes. However, the practical running environment of the contact net insulator is complex and various, and stain components attached to the surface of the contact net insulator are obviously different due to different working conditions such as regions, climatic conditions, industrial pollution degrees and the like, and the contact net insulator has stubborn impurities such as greasy dirt, metal dust and the like, easily-dissolved substances such as dust, salt and the like, and special pollutants such as biological dirt and the like. This complex contamination situation makes it difficult to cope with the single cleaning mode comprehensively. For example, high-pressure water flushing has a good effect on loose dust, but has limited capability for removing greasy dirt, laser cleaning can accurately remove part of stubborn stains, but has low cleaning efficiency on a large area, a mechanical cleaning device can damage the surface of an insulator, and dry ice cleaning is limited in use under a specific environment. Therefore, the development of the multifunctional cleaning device is necessary, various cleaning principles are integrated, and the cleaning modes can be flexibly switched or combined according to the stain types and the pollution degrees of different insulators, so that the efficient and safe cleaning of various complex stains is realized, and the stable performance and the power supply safety of the contact net insulators are ensured. At present, the intelligent power grid and intelligent traffic depth are fused, and the cleaning maintenance of the contact network insulator is beyond the maintenance scope of the traditional equipment, so that the contact network insulator is a system engineering for guaranteeing the safety of a power supply system, improving the operation efficiency and reducing the cost of the whole life cycle. By constructing a closed loop system of monitoring, cleaning and evaluating, the dynamic optimization of the performance of the insulator can be realized, and a solid technical barrier is constructed for the high-quality development of rail transit. Disclosure of Invention The invention aims to solve the problem that the contact net insulator is difficult to realize high-efficiency, accurate and automatic cleaning due to different dirt types and pollution degrees, and provides reliable guarantee for intelligent operation and maintenance of the contact net insulator, improves cleaning operation effect and efficiency and reduces operation and maintenance cost through innovative system desi
