Description

Technical Field

[0001] The invention relates to the technical field of pipeline cleaning, and in particular to a device for cleaning debris inside a concrete pipe. Background Art

[0002] Concrete pipes are pipes made of concrete or reinforced concrete, used to transport fluids such as water, oil, and gas. They can be divided into four types: plain concrete pipes, ordinary reinforced concrete pipes, self-stressed reinforced concrete pipes, and prestressed concrete pipes. When installing concrete pipes, it is easy for debris to enter the pipes. A large amount of debris deposition will cause pipe blockage, so it is necessary to remove the debris in the pipes to ensure the flow inside the concrete pipes.

[0003] For example, the invention with application number: CN202010551500.X relates to the technical field of slag cleaning equipment, and specifically relates to a slag cleaning device inside a concrete pipe, comprising a slag breaking up component, a breaking up rotating mechanism, a rotating linkage component, a head pipe, a middle pipe, an expansion component, a scraper, an expansion drive mechanism and a slag suction mechanism. One end of the head pipe is connected to the middle pipe, and the connection is hollow. The rotating linkage component is installed at the other end of the head pipe. The slag breaking up component surrounds the output end of the rotating linkage component. The breaking up rotating mechanism is installed at the middle pipe. The expansion component is located at the connection between the middle pipe and the head pipe. The scrapers are respectively installed at the output ends of the expansion components. The expansion drive mechanism is installed in the middle pipe. The output end of the slag suction mechanism is located at the connection between the middle pipe and the head pipe. This technology can break up, scrape and suck up the slag in the concrete pipe, so that the inside of the concrete pipe remains clean.

[0004] When using the existing debris cleaning devices inside concrete pipes, most of them need to crush the blocky debris in the pipe and scrape off the debris attached to the inner wall of the pipe.
