Pipeline operation equipment with automatic speed regulation

Abstract

The embodiment of the invention provides pipeline operation equipment with automatic speed regulation, which belongs to the technical field of pipeline operation. The pipeline operation equipment comprises a cylindrical framework, a plurality of leather bowls or supporting wheels, a baffle board, a speed sensor and a controller, wherein two ends of the cylindrical framework are open to pass fluidin and out; the leather bowls or the supporting wheels support the cylindrical framework in a pipeline and make the equipment advance in the pipeline; the baffle board is arranged in a framework cylinder, and the shape and the size of the baffle board are adaptive to a cross section which is vertical to the axial direction of the cylindrical framework; the speed sensor is used for acquiring the instantaneous speed of the equipment during advancing; the controller is used for judging whether an instantaneous speed value acquired by the speed sensor corresponds to the current autorotation angleof the baffle board; and if the instantaneous speed value acquired by the speed sensor does not correspond to the current autorotation angle of the baffle board, the baffle board is controlled to rotate to an angle corresponding to the instantaneous speed value according to a preconfigured corresponding relation between the instantaneous speed value and the rotation angle. The pipeline operation equipment has a simple structure, and can automatically regulate the advancing speed according to the condition in the pipeline.

Description

technical field [0001] The invention belongs to the technical field of pipeline operation, in particular to a pipeline operation equipment capable of automatic speed regulation. Background technique [0002] In order to effectively repair, maintain, and clean the pipelines, pipeline operation equipment is generally used in the pipelines to achieve various complex pipeline operations. For example, pipe pigs are used to clean pipelines; defects such as deformation and corrosion of pipelines are detected by pipeline detectors, and defects such as pipelines are detected and dealt with in advance to prevent these potential dangers from causing major accidents in the future; pipeline robots are used to perform more complex repairs, maintenance, and cleaning. Dirt work. [0003] However, more and more pipeline transportation tends to be characterized by large flow, high pressure, and fast flow rate, which leads to the excessive speed of pipeline operation equipment, which not only...

Problems solved by technology

[0003] However, more and more pipeline transportation tends to be characterized by large flow, high pressure and fast flow velocity, which leads to the excessive speed of pipeline operation equipment, which not only makes the pipeline operation effect unsatisfactory, but also causes damage to the pipeline itself and the operation equipment. injury, risk of accident

Although there are some schemes for controlling the travel speed of pipeline operation equipment in the prior art, these schemes have complex structures, difficult to solve the resistance fluid resistance coefficient theory, and large power consumption for mechanism movement, so it is difficult to popularize and apply
