When the supporting arm is in a contracted state, the supporting arm is not in contact with the pipe wall, and the supporting leg 2-1 does not have any influence on the forward walking of the walking support 4; the supporting arm is in an open state, the supporting arm is in direct contact with the pipe wall, and the friction force between the supporting leg 2-1 and the pipe wall becomes the resistance of the walking support 4 to walk forwards, so that the aim of forcing the walking support 4 to stop is achieved, and conditions are created for the fixed-point cleaning mechanism 3 to perform fixed-point secondary cleaning on residual dirt.

Specifically, the working process of the pipe cleaning device of the present embodiment is described with reference to the accompanying drawings to further explain the technical solution of the present application:
1. the walking and cleaning process comprises the following steps:
as shown in figure 1, the cleaning device is placed in a pipeline, the inclined blades 1-1 in the primary cleaning structure 1 convert the kinetic energy of water flow into torque for driving the cleaning wheels 1-2 to rotate clockwise under the action of the water flow, and the cutting edges 1-3 on the outer walls of the cleaning wheels 1-2 cut dirt on the inner walls of the pipeline so as to remove the dirt.
When the primary cleaning structure 1 cleans the inner wall of the pipeline, the blades arranged on the power wheel 3-1 also convert the kinetic energy of the water flow into torque for driving the power wheel 3-1 to rotate under the action of the water flow, namely the power wheel 3-1 also synchronously rotates clockwise.
The power wheel 3-1 transmits clockwise rotation torque to the rotating frame 3-4 through the spring teeth 3-2, and the rotating frame 3-4 rotates clockwise along with the power wheel 3-1.
As the friction wheel 3-10 is connected on the rotating frame 3-4, the friction wheel 3-10 is in friction fit with the connecting sleeve 2-7, and the connecting sleeve 2-7 is connected with the shaft sleeve 2-5 through the spring latch 2-6 on the right side of the shaft sleeve 2-5.
The external thread of the shaft sleeve 2-5 is matched with the movable nut 2-3, namely, the rotary motion of the shaft sleeve 2-5 can be converted into the linear motion of the movable nut 2-3 through the thread connection structure between the two.
Three supporting legs 2-1 are hinged on the circumferential direction of the support 4, and a connecting rod 2-2 is hinged between the supporting legs 2-1 and the movable nut 2-3.
The left side of the shaft sleeve 2-5 is fixedly provided with a spring strip 2-4, the other end of the spring strip 2-4 is fixedly arranged on a clamping groove 4-1 on the support 4, the spring strip 2-4 provides stretching pretightening force, the pretightening force can enable the shaft sleeve 2-5 to rotate anticlockwise so as to enable the movable nut 2-3 to move leftwards, the movable nut 2-3 moves leftwards to drive the connecting rod 2-2 to drive the supporting foot 2-1 to open, namely the pretightening force is used for enabling the supporting foot 2-1 to open.
When the rotating frame 3-4 rotates clockwise, the friction wheel 3-10 is driven to transmit clockwise rotation torque to the shaft sleeve 2-5 through the connecting sleeve 2-7, the clockwise rotation torque is larger than the anticlockwise torque generated between the clockwise rotation torque and the shaft sleeve 2-5 by the spring strip 2-4, and the shaft sleeve 2-5 can still rotate clockwise.
Therefore, when the shaft sleeve 2-5 rotates clockwise, the movable nut 2-3 moves rightwards, the spring strips 2-4 continue to stretch, the supporting feet 2-1 shrink, when the movable nut 2-3 moves to the rightmost end, the shaft sleeve 2-5 cannot rotate any more, the supporting feet 2-1 shrink to the state with the smallest radius, and the connecting sleeve 2-7 and the spring latch 2-6 on the right side of the shaft sleeve 2-5 are changed into the relative sliding state from the state of simultaneous rotation.
At the moment, only the support frame 4-2 supports the pipe wall to provide certain resistance, and the whole device is still in a walking state.
Meanwhile, the power wheel 3-1 drives the rotating frame 3-4 to synchronously rotate, and the detection rod 3-5 fixed on the rotating frame 3-4 also synchronously rotates in the circumferential direction to scan and detect the cleaning condition of the pipe wall.

(2) Fixed point cleaning
When the rotating frame 3-4 does not rotate any more, the power wheel 3-1 still continues to rotate clockwise, the power wheel 3-1 is meshed with a second bevel gear 3-6 fixed on the rotating frame 3-4 through a first bevel gear 3-3 arranged on the side face of a wheel axle of the power wheel 3-1, the second bevel gear 3-6 continues to be meshed with a third bevel gear 3-7, the third bevel gear 3-7 drives a belt pulley 3-8 to rotate, the belt pulley 3-8 drives a fixed point cleaning wheel 3-9 to rotate, and a cutting edge of the fixed point cleaning wheel 3-9 is just flush with the tail end of a detection rod 3-5 during rotary cutting, so that the fixed point cleaning wheel 3-9 can clean residual dirt at a fixed point.
And the walking recovery cleaning process:
after fixed-point cleaning is finished, dirt disappears, resistance on the detection rod 3-5 disappears, the rotating frame 3-4 recovers to rotate, the friction wheel 3-10 is driven to recover to rotate so as to drive the connecting sleeve 2-7 to drive the shaft sleeve 2-5 to rotate clockwise through the spring latch 2-6, the shaft sleeve 2-5 rotates clockwise, the moving nut 2-3 generates linear displacement to move to the rightmost end until the connecting sleeve 2-7 and the spring latch 2-6 slide relatively, the shaft sleeve 2-5 does not rotate clockwise any more, the supporting leg 2-1 retracts to the minimum radius (initial position) again, and the cleaning device recovers to a walking state.
