Telescopic self-crawling sweeper in wind tunnel pipeline

Abstract

The invention discloses a telescopic self-crawling sweeper in a wind tunnel pipeline, and relates to the field of running assisting devices. The sweeper comprises a cleaning disc, a motor, a telescopic mechanism, a dust collection mechanism, a sliding body and a main crawling body, wherein the motor is horizontally placed, and the dust collection mechanism is arranged in the middle of the motor; the cleaning disc is of a disc-shaped structure, and an output shaft of the motor is fixedly connected with the axis of the cleaning disc; the main crawling body is of a columnar structure with a T-shaped section; the main crawling body wraps the outer wall of the motor in the axial direction; the sliding body is of a disc-shaped structure; the sliding body axially sleeves the outer wall of the main crawling body; the telescopic mechanism is fixedly arranged between the sliding body and the main crawling body in the axial direction; and the self-crawling sweeper is arranged in the inner wall ofan external compression tube in the axial direction. Automatic cleaning work of the compression tube in a free piston shock tunnel is achieved, and the running efficiency and safety of similar wind tunnels can be improved.

Description

technical field [0001] The invention relates to the field of operation auxiliary devices, in particular to a telescopic self-crawling cleaning machine in a wind tunnel pipeline. Background technique [0002] In the free piston shock wave wind tunnel, due to the high-speed movement of the free piston inside and the high temperature and high pressure environment generated in the rear area, a small amount of material on the free piston support ring, friction ring and stop mechanism will fall off due to compression, and even Part of the exfoliated material will adhere to the inner wall of the compression tube, which will have an unsafe effect on the operation of the free piston in the next test. At present, the cleaning work for the compression tube is done manually. However, the length of the compression tube is long, the internal space is small, and there is toxic gas generated due to high temperature after the test, which is not conducive to personnel entering for high-qualit...

[0002] In the free piston shock wave wind tunnel, due to the high-speed movement of the free piston inside and the high temperature and high pressure environment generated in the rear area, a small amount of material on the free piston support ring, friction ring and stop mechanism will fall off due to compression, and even Part of the exfoliated material will adhere to the inner wall of the compression tube, which will have an unsafe effect on the operation of the free piston in the next test

At present, the cleaning work for the compression tube is done manually, but the length of the compression tube is long, the internal space is small, and there is toxic gas generated by high temperature after the test, which is not conducive to personnel entering for high-quality and efficient cleaning work
