[0041] like Figure 1-Figure 6 As shown, the method for removing pulverized coal in the coalbed methane mining pipeline of the present invention comprises the following steps:
[0042] Step 1, put the pipeline robot into the pipeline 6 of coalbed methane mining, the controller on the ground controls the walking mechanism of the pipeline robot to contact the inner wall of the pipeline 6, and then start the walking mechanism to move forward along the inner wall of the pipeline;
[0043] Step 2, while the pipeline robot is traveling on the inner wall of the pipeline, the pipeline robot is controlled to carry out a rotating removal operation to remove the pulverized coal attached to the inner wall of the pipeline 6;
[0044] Step 3: Control the pipeline robot to collect and store the cleaned pulverized coal;
[0045] Step 4: compress the stored pulverized coal, and squeeze out the water, so as to collect more pulverized coal during the removal operation;
[0046] Step 5. When th...
