Description

An omnidirectional mobile intelligent street lamp cleaning device and cleaning method

technical field

The invention belongs to the field of street lamp cleaning, and in particular relates to an omnidirectional mobile intelligent street lamp cleaning device and a cleaning method.

Background technique

With the improvement of my country's road system construction, the number of motor vehicles on the road is increasing. The increase in motor vehicles will inevitably lead to more serious pollution of street lamps at the same time, and the lighting function of seriously polluted street lamps will be affected. Greatly discounted, it constitutes a hidden danger to the safe driving of the road, so the street lamps must be cleaned in time to ensure the normal operation of the road. At present, the main device for street lamp cleaning is the traditional street lamp cleaning vehicle, which uses a larger motor vehicle as a platform to send cleaning personnel to the lampshade of the street lamp for cleaning through a lifting platform, but this method has great disadvantages. First of all, cleaning personnel must stand at a high place to clean the street lamps, and there is a risk of falling if they are not careful; secondly, the platform motor vehicle is too large, which will hinder road traffic during work; the waste water generated during the street lamp cleaning process It cannot be recycled and causes damage to the environment; the steering of motor vehicles is very cumbersome and takes a lot of time, and the cleaning efficiency is low; it must require the cooperation of multiple workers and consume a lot of manpower.
