The pipeline cleaning is an operation of cleaning the inner wall of the pipeline to prevent scaling, and during the transportation process of oil, some viscous substances are often deposited on the inner wall of the pipeline, especially wax in crude oil transportation.
However, in the prior art, most of the existing pipeline cleaning machines use a pipeline alkali cleaning machine, which is generally used as a main tool for cleaning and dredging the pipeline.
In practice, the following drawbacks are found:
1. because the rigidity of the spring for transmitting power is limited, the power of the motor is limited, and the spring can be wound and damaged by slight over-force or over-speed, so that the spherical metal knocking head or the spherical spring cannot effectively play a cleaning function;
2. if a metal knocking ball is used, due to the high hardness of the metal knocking ball, the inner wall of the pipeline can be damaged while the pipeline is cleaned, and the metal knocking ball has a certain volume, can be clamped at the inflection point (P-shaped bend, L-shaped bend and the like) of the pipeline and cannot advance and retreat, and even more, can be taken out only by disassembling the pipeline;
3. during the process of cleaning the pipeline, the spherical metal knocking ball or the spherical spring is generally positioned at the bottom of the pipeline due to the gravity action of the spherical metal knocking ball or the spherical spring, and the top of the pipeline cannot be cleaned, so that the whole inner wall of the pipeline cannot be completely cleaned, and dead corners are left;
4. because the spring for transmitting power only has a single winding direction and cannot change the steering direction, the motor only can keep the single steering direction, so that the metal knocking ball or the ball-shaped spring cannot be manually steered in the pipeline, and cannot be released through reverse rotation when the metal knocking ball or the ball-shaped spring is excessively wound or stuck with dirt.
SUMMERY OF THE UTILITY MODEL
The utility model aims at solving the shortcoming that exists among the prior art, clear alkali metal strikes ball or spherical spring not enough, can be quick, and the efficient clearance is various in non-metallic material's pipeline, alleviates personnel's intensity of labour.
