The flexible shaft is made of springs, the pitch of the springs is between 30mm and 50mm, and the pitch is between 15mm and 25 mm. The snap spring device and the spring are connected by screw threads which take the spring as a screw rod and the snap spring device as a nut.
And a limiting plate group 5 with a gradually reduced thickness is also arranged on the inner wall of the outer layer storage cylinder. The limiting plate group 5 comprises 10 strip limiting plates which are uniformly distributed along the inner wall of the outer layer storage cylinder.
A guide cylinder 8 made of nylon is arranged at the front end of the inner sleeve 7, one end of the guide cylinder 8 corresponds to the size of the inner sleeve 7, the diameter of the other end of the guide cylinder is gradually reduced to be in a cone shape, and the inclined plane of the cone is inclined at an angle of between 30 and 55 degrees. The design reduces the friction force of the flexible shaft in and out.
The roller power source and the clamping power source comprise hydraulic motors, and the hydraulic motors are connected with a PLC control system in a circuit mode. When in use, a worker can input from the control panel to control the winding and unwinding speed of the cable.
The outer layer storage cylinder is provided with a dredging hole and an observation hole. The residual condition of the sludge in the equipment is convenient to observe.
A flexible shaft tube body is made of an elastic structure, the head end of the flexible shaft with elasticity is sleeved in a clamp spring device 1, the tail end of the flexible shaft tube body is fixedly arranged at the bottom in a roller, the clamp spring device 1 and the roller are respectively connected with independent power sources, the flexible shaft is coiled in a space formed by an inner sleeve 7 and an outer roller in turn under the driving of self elastic force, the steering among the power sources is controlled to control the retraction of the flexible shaft, the rotating speed difference of the roller and the clamp spring device is controlled to control the retraction speed of the flexible shaft, and a limiting plate group 5 which converts the elastic force and guides the positioning of the elastic force during the wire retraction is arranged in an outer storage tube 4.

The axial movement of the spring can be realized by changing the rotating speed of the jump ring device. The rotating speed is a vector, and the rotating direction of the roller is positive with the same rotating direction of the spring; if the spring is required to rotate only but not axially move, the rotating speed of the jump ring device is equal to the rotating speed of the roller; when the spring is required to advance, the rotating speed of the jump ring device is smaller than the speed of the roller; when the spring is required to retreat, the rotating speed of the jump ring device is higher than that of the roller. The device can realize stepless speed regulation of the axial moving speed of the spring.
