Dust collection mechanism on air duct cleaning robot and air duct cleaning robot

Abstract

The invention discloses a dust collection mechanism on an air duct cleaning robot, which comprises a dust collection port and a car body, wherein a rocker arm is hinged on the car body, and the rocker arm is ascended, descended and positioned under the control of a driving mechanism; a connecting base is fixedly arranged in front of the car body, a floating plate is connected on the connecting base through a long guide bar, the floating plate and the connecting base are vertically connected in a sliding manner and can rotate relatively, the rocker arm can impose the downward pressure on the floating plate, and the left side and the right side of the floating plate are connected with the connecting base or the car body through tension springs respectively; and the dust collection port is fixed on a press plate, universal wheels are arranged below the press plate, the press plate and the floating plate are vertically connected in the sliding manner, a compression spring is directly arranged between the press plate and the floating plate, the upper end of the compression spring leans against the floating plate, and the lower end of the compression spring leans against the press plate. The invention further discloses the air duct cleaning robot containing the dust collection mechanism. The technical scheme has a self-adaptive structure, thereby being capable of carrying out self-adjustment according to the complicated situations of elbows, uplifts, depressions and the like in a pipeline of an air duct and further ensuring the good dust collection effect.

Description

technical field [0001] The invention belongs to the technical field of pipeline cleaning, and relates to an air duct cleaning robot (remote control trolley) for performing dust suction operations in central air-conditioning ducts, in particular to a dust collection mechanism installed on the air duct cleaning robot (remote control trolley) . Background technique [0002] The central air-conditioning and ventilation system undertakes the important task of delivering cold, warm and fresh air to people. However, because the air-conditioning duct is relatively closed, the temperature and humidity inside are very suitable for the growth and reproduction of microorganisms, especially fungi. If the central air conditioner is not cleaned for a long time, a large amount of dust will easily accumulate in the ventilation duct, and insect corpses that enter in the future will easily breed a large number of harmful bacteria. After the human body inhales it, the mild ones feel unwell, an...

AI Technical Summary

Problems solved by technology

In case of an obstacle, if the suction port cannot be lifted or turned in time, it will affect the progress of the car; in case of a depression, the suction port will leave the inner surface of the air duct, and the suction will be weakened, which will affect the dust collection effect

Only when the suction port is close to the surface, the dust suction effect is the best; if the adjustment is too much, the car body will be jacked up; if the adjustment is not enough, the suction will drop; manual control of the rocker arm lifts frequently, seriously affecting the work efficiency and control effect not good too
