Abstract

A pipeline robot specially used to remove pulverized coal in coalbed methane mining pipelines, including a dredging device, a driving device and a storage device. Both the driving device and the storage device are provided with power modules, and the dredging device is arranged at the front end of the driving device. The driving device and The center of the storage device is provided with front and rear transparent water holes, and a central water hose is connected between the rear end of the water hole in the driving device and the front end of the water hole in the storage device. Several pulverized coal conveying hoses are arranged between the front ends of the storage device, and several traveling mechanisms are arranged on the outer circumferences of the driving device and the storage device. The invention does not affect the normal mining work of coalbed methane when cleaning the pulverized coal, and stores the cleaned pulverized coal after the inner wall of the pipeline is blocked and dredged, with convenient operation, high degree of automation and strong reliability.

Description

technical field [0001] The invention belongs to the technical field of coalbed methane mining, and in particular relates to a pipeline robot specially used for removing coal powder in coalbed methane mining pipelines. Background technique [0002] Hydraulic fracturing is currently the most commonly used and most effective technical means in coalbed methane mining and coalbed methane stimulation. The friction between the fracturing proppant and the fracturing fluid system flowing through the surface of the coal seam and the coal will produce pulverized coal, and the pulverized coal will block the natural fracture system of the coal seam and the pores filled by the proppant, affect the desorption and migration of coalbed gas, and cause the permeability of the coalbed to increase. permanent damage, seriously affecting the gas production of coalbed methane wells. The mixing of coal powder will also increase the viscosity of the liquid, or block the tip of the crack, resulting i...
