A variable-diameter pipeline cleaning device

Abstract

The invention discloses a diameter-adjustable pipeline cleaning device. The diameter-adjustable pipeline cleaning device mainly consists of a transmission shaft, cleaning rods, fixing discs, spherical hinges, brush heads, pins, support connecting rods, movable discs, springs and a handle and is characterized in that the fixing discs are fixed on the transmission shaft; the cleaning rods are connected with the fixing discs through the spherical hinges; the brush heads are connected with the cleaning rods through the pins, and the cleaning rods are connected with the supporting connecting rods through pins; the supporting connecting rods are connected with the movable discs through the spherical hinges, and the transmission shaft is connected to the handle; the springs are arranged between every two movable discs. Before the pipeline cleaning device is used, the brush heads and the cleaning rods are manually closed, and after the device enters a pipeline, the device is released; under the pulling action of the springs, the brush heads and the cleaning rods have trends of dispersing outwards, so that the brush heads are close to the pipe wall; the brush heads are connected with the cleaning rods through the pins, and the brush heads have the function of automatic righting in the axial direction of the pipeline; the brush heads close to the pipe walls are indirectly driven by the handle to rotate, so that the purpose of cleaning the pipeline is realized.

Description

technical field [0001] The invention relates to a cleaning device, in particular to a variable-diameter cleaning device for pipelines, and belongs to the technical field of mechanical design or environmental protection. Background technique [0002] In industrial production and daily life, pipes are widely used. During the installation process of the pipeline, residues such as welding slag, dust and sand may be generated inside the pipeline; at the same time, because the transported substances often contain various salts, impurities, sulfides and bacteria, etc., the pipeline will be damaged after a certain period of use. There are phenomena such as scaling and corrosion, so the pipeline needs to be cleaned. At present, the more commonly used pipeline cleaning methods mainly include three types: (1) chemical cleaning method, that is, through the selection and use of chemical agents, the purpose of cleaning is achieved through chemical reaction characteristics. The advantage ...

Problems solved by technology

However, these companies seldom introduce mature cleaning technologies, usually by using straight rods and cotton cloths for manual cleaning, which is less efficient

[0004] Through search, it is found that there are few pipes with different inner diameters in the prior art or devices
