Technical Field

The invention belongs to the technical field of pipeline cleaning, and particularly relates to a cleaning device for an inner wall of a pipeline based on a reaction force principle.

Background

Pipelines are devices for transporting gases, liquids or fluids with solid particles, which are connected by pipes, pipe connectors, valves and the like, have a wide range of applications, and are mainly used in water supply, drainage, heat supply, gas supply, long-distance transportation of oil and gas, agricultural irrigation, hydraulic engineering and various industrial devices.

Before a pipeline is assembled on a product, the inner wall of the pipeline generally needs to be cleaned, such as a heat energy seamless steel pipe for a boiler and the like, the existing pipeline cleaning mode generally cleans the pipeline by matching a high-pressure water gun held by a hand with a brush, but the water pressure of the high-pressure water gun is reduced along with the increase of a range, and the length of the brush is limited by the length, so that the pipeline cannot be effectively cleaned in the deep part of the pipeline; in addition, when the inner wall of the pipeline is washed by a brush or a high-pressure water gun, the inner wall of the pipeline cannot be effectively and comprehensively cleaned due to the fact that the operation area is strip-shaped or fan-shaped, and cleaning dead corners are easy to remain.

To this end, we propose a cleaning device for the inner wall of the pipe based on the principle of reaction force to solve the above problems.

Disclosure of Invention

The invention aims to provide a pipeline inner wall cleaning device based on a reaction force principle, which is low in operation difficulty and more comprehensive in cleaning, aiming at the problems that the existing pipeline cleaning device is inconvenient to operate and is easy to have a cleaning dead angle.

In order to achieve the purpose, the invention adopts the following technical scheme: a cleaning device for the inner wall of a pipeline based on the principle of reaction force comprises a central disc and a plurality of branch pipes fixedly connected to the side wall of the central disc, wherein the branch pipes are uniformly distributed around the axis of the central disc, pistons are connected in the branch pipes in a sliding and sealing manner, slide rods are fixedly connected to the outer side walls of the pistons, sliding parts are fixedly connected to the outer ends of the slide rods, an adjusting pipe is arranged at the upper end of the central disc, the lower end of the adjusting pipe is communicated with the central disc and the inner parts of the branch pipes to form a closed storage cavity, and a large sealing plug is connected to the opening of the;

the lower end of the branch pipe is fixedly connected with an arc pipe, the circle centers of the arc pipes are all located on the axis of the central disc, the lower end of the arc pipe is fixedly connected with a plurality of downward-inclined injection nozzles, the inclination angles of the injection nozzles are the same, the lower end of the central disc is fixedly connected with a flow distribution disc, the flow distribution disc is communicated with the arc pipe through a drainage pipe, and the lower end of the flow distribution disc is rotatably connected with a water inlet pipe.

In the above cleaning device for the inner wall of the pipeline based on the principle of the reaction force, the sliding part comprises a ball seat fixedly connected with the sliding rod and a rolling ball movably arranged in the ball seat.

In the above cleaning device for the inner wall of the pipeline based on the principle of the reaction force, the storage chamber is filled with helium gas.
