Combined multifunctional negative pressure cleaning device

Abstract

The invention relates to the technical field of aloft cleaning work, in particular to a combined multifunctional negative pressure cleaning device. The combined multifunctional negative pressure cleaning device comprises a sealing cleaning cover, a spraying unit, a cleaning unit and a negative pressure unit. In the sealing cleaning cover, a cleaning agent is sprayed through a water spraying pipeline and a sprayer, and roller brushes conduct cleaning work, so that the sealing cleaning cover provides an effective closed environment for cleaning agent spraying and work of the roller brushes. A negative pressure environment can be formed in the sealing cleaning cover through a negative pressure air pipe of the negative pressure unit, the situation that the cleaning liquid covers an excess area or used cleaning liquid overflows beyond a controllable range can be avoided by controlling the coverage area of the cleaning liquid to be within the range of the sealing cleaning cover, then secondary contamination to a working face is avoided, and dirty liquid can be conveniently recycled. Besides, the sealing cleaning cover is in a negative pressure state due to the suction force of the negative pressure air pipe, the roller brushes in the sealing cleaning cover can be better attached to a surface to be cleaned, and the glass surface cleaning effect of the roller brushes is further improved.

Description

Technical field [0001] The invention relates to the technical field of high-altitude cleaning operations, in particular to a composite multifunctional negative pressure cleaning device. Background technique [0002] Existing conventional cleaning solutions are all open or semi-open structures for liquid dissolving or softening surface dust and rolling brush cleaning operations respectively. The main drawback is that the cleaning agent is sprayed in an open space and the usage rate is low. , Recycling is difficult, and the scrubbing work of the brush is not guaranteed by sufficient cleaning fluid, and the dust carried by the brush cannot be recycled after being separated from the working surface. Instead, it is thrown out at will with the centrifugal force, ordinary working with liquid Environmental sealing is also difficult to solve the sealing problem during relative movement. [0003] In addition, there are more and more existing high-rise buildings, with a wide variety of shape...

Problems solved by technology

[0006] The object of the present invention is to provide a composite multifunctional negative pressure cleaning device on the one hand to solve the problem of spraying cleaning agents in the open space in the existing building exterior wall cleaning technology low utilization rate, difficult recycling, and serious secondary pollution; on the other hand, it solves the problems that existing robots tend to leave blank spaces when they cross obstacles, and the surface of the glass frame cannot be cleaned.
