Automatic curtain wall cleaning robot

Abstract

The invention discloses an automatic curtain wall cleaning robot which comprises a rack, a lifting flight mechanism used for controlling lifting and a posture change of the robot, a cleaning rolling brush, a side pressure propelling mechanism, and a gravity center balance power mechanism, wherein the side pressure propelling mechanism is used for providing a thrust towards the wall surface, and the side pressure propelling mechanism and the cleaning rolling brush are oppositely arranged on the two sides of the rack; and the gravity center balance power mechanism is arranged on the rack, located on the upper side and the lower side of the cleaning rolling brush and used for providing a upward thrust and a downward thrust and keeping the gravity center of the rack balanced. The robot is provided with a flying mechanism, enough friction pressure applied to the curtain wall by the robot in the cleaning process can be kept, the cleaning effect is improved, and the robot is ensured to be stable in state and safer.

Description

【Technical field】 [0001] The invention relates to an automatic curtain wall cleaning robot. 【Background technique】 [0002] The surface of the external wall is affected by the suspended grease, tiny particles and floating objects with static electricity in the air, as well as the sediment in the rainwater and the oxides of the curtain wall frame material, which will cause corrosion and pollution on the surface of the external wall, which will affect the appearance of the external wall for a long time For safety and security, the external walls need to be cleaned regularly. At present, the mainstream exterior wall cleaning method in the market is "spider-man" cleaning, and there are tools to move to the designated location with the help of lifting platforms and hanging baskets for cleaning. These cleaning methods are inefficient, labor-intensive and risky. [0003] Existing exterior wall cleaning robots on the market basically use a rope-drawn cleaning mechanism to complete ...

AI Technical Summary

Problems solved by technology

The current mainstream exterior wall cleaning method in the market is "spider-man" cleaning, and there are tools to move to the designated location with the help of lifting platforms and hanging baskets for cleaning. These cleaning methods are inefficient, labor-intensive and risky.

[0003] Existing exterior wall cleaning robots on the market basically use rope traction cleaning mechanisms to complete the cleaning operation, the cleaning efficiency is not high, and at the same time, it is impossible to clean special-shaped exterior walls

In the prior art, automatic robot cleaning is also used. For example, the patent No. 201911033830.3 discloses a curtain wall cleaning robot, and the patent No. 201811193118.5 discloses a curtain wall cleaning robot. However, most of the robots use the form of climbing on the curtain wall. Walking, use the adsorption effect between the large suction cup and the curtain wall to keep the robot fixed on the curtain wall. During the cleaning process, because the cleaning head and the curtain wall have to generate relative pressure to remove the stains on the surface of the curtain wall, the relative pressure is stable for the adsorption force of the robot. There is a big hidden danger, and there are some groove designs on some curtain walls, and the unevenness of the appearance will also affect the walking problem of climbing robots. On the one hand, there are potential safety hazards, and on the other hand, the cleaning effect is not good.
