Description

TECHNICAL FIELD

[0001] The utility model relates to pipeline cleaning technical field, concretely relates to a kind of cleaning equipment of oilfield natural gas exploitation pipeline. BACKGROUND

[0002] Natural gas refers to all gases in nature, including the atmosphere, water circle and lithosphere The gas formed by various natural processes, while the definition of natural gas commonly used by people for a long time is a narrow definition from the energy angle, which refers to the mixture of hydrocarbon and non-hydrocarbon gases naturally stored in the stratum, and in petroleum geology, it usually refers to oilfield gas and gas field gas, which is mainly composed of hydrocarbons and contains non-hydrocarbon gases.

[0003] After searching, it is found that the application No. CN201920587039.6, named natural gas exploitation pipeline cleaning device, proposes that many devices are needed in the process of natural gas exploitation, and pipeline is an indispensable part. During the process of natural gas exploitation, the exploitation pipeline needs to be cleaned regularly, otherwise it will affect the exploitation of natural gas, and reduce the service life of the pipeline. However, the current pipeline equipment is very large, which is not practical for natural gas exploitation in the field. The smaller cleaning equipment does not have good cleaning effect. Through the cooperation of delivery pump, water inlet pipe and cleaning liquid tank, the water has more impact force when cleaning the inside of the pipeline, and the cleaning liquid is matched. The dirt inside the pipeline can be cleaned thoroughly. By setting driving motor, driving gear and linkage gear, the connecting head can rotate during cleaning, so as to improve the impact force, and the brush can rotate, so as to clean more thoroughly during cleaning. By setting telescopic connecting pipe, stop block, telescopic outer pipe and telescopic pull groove, different length pipes can be cleaned, so as to adapt to a wider range. However, the adjusting range and total length of the telescopic structure are limited in actual use, and the pipeline with large length cannot be cleaned efficiently and conveniently. The overlong telescopic structure will produce the problem of one end drooping when cantilevered, which affects the stability of use and limits the application range. It is also difficult to effectively adjust according to the pipe diameter, and the structure is complex, which can be further improved.

[0004] Therefore, based on this, the utility model technical scheme is proposed. UTILITY MODEL CONTENT
