Variable diameter pipe scrubbing tool

Abstract

The invention relates to a cleaning tool, in particular to a variable-diameter pipeline brushing tool. The variable-diameter pipeline brushing tool comprises a shell, a main pipeline, a rotating regulating device, a diameter reset device and a brushing device. The main pipeline is arranged in the shell and penetrates the shell. The rotating regulating device is arranged at the rear end of the shell. The diameter reset device is arranged in the shell. The brushing device is arranged around the shell. The rear half portion of the brushing device is inserted in the shell and communicates with the main pipeline. A spring is installed between the front half portion of the brushing device and the shell. When the variable-diameter pipeline brushing tool is inserted in a pipeline with an elliptical section or a pipeline with an uneven diameter, the brushing device makes contact with the wall of the pipeline under the action of the spring, and the variable-diameter pipe brushing tool can adapt to cleaning of pipelines of different diameters. In addition, the variable-diameter pipeline brushing tool can communicate with a faucet through the pipeline, flushing is conducted while the wall of the pipeline is brushed, the cleaning effect is better, and efficiency is higher.

Description

technical field [0001] The invention relates to a cleaning tool, in particular to a variable-diameter pipeline scrubbing tool. Background technique [0002] In terms of pipeline cleaning technology, the cleaning of the inner wall of the pipeline is one of the most important and difficult aspects to perform. Generally, brushes, corrosive liquids, elastic wire ropes or robots are used for cleaning. For shorter pipes, brushes or elastic wire ropes are generally used for cleaning, and these tools are manually operated to make the cleaning part rub against the inner wall of the pipe to achieve the purpose of cleaning. The cleaning tool has a small contact area with the inner wall of the pipe and the cleaning efficiency is low.

Problems solved by technology

For shorter pipes, brushes or elastic wire ropes are generally used for cleaning, and these tools are manually operated to make the cleaning part rub against the inner wall of the pipe to achieve the purpose of cleaning. The cleaning tool has a small contact area with the inner wall of the pipe and the cleaning efficiency is low.

[0003] In the prior art, the brush head is set on the motor to improve the cleaning efficiency. Since the determined contact area between the cleaning tool and the inner wall of the pipe basically does not change much, in order to increase the contact area between the two, the cleaning diameter of the general cleaning tool should be exactly equal to the diameter of the inner wall of the pipe. , but this kind of cleaning tool is highly targeted, resulting in a narrow range of use. If you want to clean pipes with different diameters, you need to replace the brush heads with matching diameters. When the cross-section of the pipe is oval or the diameter of the pipe is uneven, It is not possible to make the cleaning diameter equal to the pipe diameter by replacing the matching brush head

[0004] Chinese patent application number: 201610047373.3, application date 2016.01.25, invention name: a crawler wheel pipe cleaning robot that can adapt to different pipe diameters. change; this invention has the following problems: on the one hand, the device utilizes a large number of electrical components, and the cost is too high; The reciprocating movement will make the speed of the brush become zero when it moves to the left and right limit points, which will affect the cleaning effect; in addition, the device can only be cleaned by friction between the brush and the stain, without any solvent participation, and the cleaning effect and efficiency are low
