Tunnel cleaning system based on piston effect and operation method of tunnel cleaning system

Abstract

The invention discloses a tunnel cleaning system based on a piston effect. The tunnel cleaning system comprises a train, a ground cleaning device, a scratch-resistant automatic retractable air curtain device and a recycling cleaning device, wherein the train comprises a control cabin, a power control cabin, a tray and travelling parts; the control cabin is arranged at the front end part of the upper surface of the tray; the power control cabin is mounted closely behind the control cabin; the ground cleaning device is mounted at the front end part of the lower surface of the tray; the scratch-resistant automatic retractable air curtain device is mounted at the middle position of the outer contour surface of the control cabin or at the rear end of the outer contour surface of the power control compartment; the recycling cleaning device is fixedly mounted at the rear end part of the upper surface of the tray; and the middle part of the upper surface of the tray is an unoccupied part. The invention discloses an operation method of the tunnel cleaning system based on the piston effect. According to the system, filtering and purification are performed in the manners of collection of large-volume garbage, dust reduction with negative ions, electrostatic dust removal, fine filtration and the like, the purified air is exhausted to the rear end of the train through an exhausting device, and finally the purpose of cleaning the tunnel is achieved.

Description

technical field [0001] The invention relates to the technical field of tunnel cleaning, in particular to a piston effect-based tunnel cleaning system and an operating method thereof. Background technique [0002] With the rapid development of China's economy and the gradual acceleration of urbanization, the scale of cities continues to expand, and urban traffic is becoming more and more congested. In order to alleviate traffic pressure, many cities are vigorously developing subways. With the rapid increase of subway mileage, the cleaning work in subway tunnels is becoming increasingly heavy. The operating environment of the subway tunnel not only affects the beauty of the environment inside the subway tunnel, but also poses a threat to the safety of subway vehicles. Therefore, keeping the subway tunnel clean is an important part of ensuring the safe operation of the subway. [0003] According to the "2014-2018 China Urban Rail Transit Market In-Depth Analysis Report" relea...

Problems solved by technology

But the existing problem of the enforcement of this method is that the consumption of a large amount of water resources and electric power energy and the unfavorable that a large amount of spraying water bring to the operation of train and the safety of passengers

In addition, the running speed of the car is within 5km / h, which greatly reduces the cleaning efficiency

[0009] To sum up, although the starting point of the above methods is to effectively clean the subway tunnel, each method has a fatal flaw, that is, it needs to consume a lot of electric energy and Only low speed operation can achieve the expected effect, so that the cleaning efficiency is too low

In addition, the water washing part involved in the latter two methods will not only consume a large amount of water resources, but also a large amount of spraying water will cause moisture in the subway tunnel, and even freeze in winter, which will affect the operation of the train and the safety of passengers. bring great disadvantage
