Mechanic type friction feedback central air conditioner pipeline cleaning mechansim

Abstract

The invention discloses a mechanical friction feedback central air-conditioning pipeline cleaning mechanism. The output power of the motor drives the driving gear, and the driving gear drives two groups of double chute swing mechanisms with the same structure and symmetrically installed on the cleaning base to rotate. Brushes are mounted on the driven pulleys of the two double chute mechanisms. The two pairs of chutes and holes on the cleaning base and the brush holder are connected through shafts to form a double chute swing mechanism, and the brush can be cleaned against the wall through friction feedback, so that it can be cleaned when there is a walking error and a change in the pipe section. Effective cleaning, and the greater the friction force of the wall surface, the greater the positive pressure of the brush on the wall surface, so the cleaning efficiency is higher when the wall surface is dirtier. The fastening mechanism adjusts the tension of the belt, thereby adjusting the cleaning force, and realizes the adjustment of the cleaning force for pipelines with different cleaning difficulties. The transmission and feedback of the whole mechanism are all mechanical, with low requirements on the working environment, good stability and low production cost.

Description

technical field [0001] The invention relates to a central air-conditioning duct type ventilation system cleaning machine, in particular to a mechanical friction feedback central air-conditioning duct cleaning mechanism. Background technique [0002] In recent years, with the continuous progress and development of my country's national economy and various social undertakings, the central air-conditioning system has been used on a large scale, but the air pollution caused by it cannot be cleaned in time has attracted people's attention, especially in After the outbreak of SARS in the spring of 2003, people became more aware of the importance of regular cleaning of the central air-conditioning duct system. The country has promulgated the corresponding national standard "Code for Cleaning of Air Conditioning and Ventilation System" GB19210-2003, which requires that the central air conditioning and ventilation system must be cleaned regularly. This design is an automatic working ...

AI Technical Summary

Problems solved by technology

The cleaning of central air-conditioning duct ventilation system has just emerged in China. Most of the cleaning robots imitate the design concept of foreign four-wheel drive as the brush carrier. Many products do not meet the needs of the Chinese market, and in terms of cleaning variable-section pipes and vertical pipes It has a shortpart
