Pipe blind hole cleaning device

Abstract

The invention relates to the technical field of cleaning devices, and in particular, discloses a blind hole cleaning device. The blind hole cleaning device comprises a shell, a cylinder, a heating device, a first piston, an automatic reciprocating cylinder, an automatic reciprocating cylinder switching device, a cleaning brush, a second piston, a spring and a pocket. The shell is provided with a first opening and a second opening; the cylinder communicates with the upper side of the shell; a heating device is arranged on the outer wall of the cylinder; the first piston is slidingly matched inthe shell, and is connected with a handle extending outside the shell; the automatic reciprocating cylinder is arranged in the shell, and an output shaft thereof is opposite to the first opening; thecleaning brush is arranged on the output shaft; the automatic reciprocating cylinder switching device is arranged on the handle; one end of the spring is connected with the shell, and the other end isconnected with the second piston; the second opening is formed in the connecting place of the spring, in a natural state, with the second piston; and the pocket is provided. The blind hole cleaning device can efficiently clean blind holes and lengthen the cleaning effect, and can be widely used for cleaning the blind holes in pipe inner walls.

Description

technical field [0001] The invention relates to a cleaning device, in particular to a blind hole cleaning device. Background technique [0002] At present, there are few researches on the cleaning process and special equipment of blind holes. The traditional way to clean blind holes is: spray cleaning. [0003] This cleaning method is that the pressure cleaning fluid is sprayed onto the blind hole through different nozzles, and the cleaning effect is achieved through the impact force. The disadvantage of this spray cleaning method is that stubborn impurities such as oil stains in the blind holes cannot be cleaned only by water pressure impact, and the work efficiency is low. [0004] In order to solve the above problems, Chinese patent CN104070043A discloses a blind hole cleaning tool, including a straight shank twist drill and a handle, the straight shank twist drill is set in the hole in the middle of the handle and fastened to form a T-shaped structure. There are two ax...

Problems solved by technology

[0005] The method of cleaning the blind hole in the above-mentioned patent documents is to remove the sludge by turning the straight handle twist or using the through hole on the straight handle to apply force, but because the drill bit or the through hole extending into the blind hole has a small contact range with the sludge in the blind hole or Not comprehensive, which will cause a layer of sludge to remain on the wall of the blind hole, making the environment of the wall of the blind hole humid after cleaning, so that the adsorption speed of impurities will be accelerated when it is used again, and the cleaning effect will not last long
