As shown in fig. 5, the pumping mechanism 8 includes an annular shell 81 sleeved on the outer peripheral surface of the casing 1, the section of the annular shell 81 is U-shaped, two side edges of the annular shell 81 and the outer arm of the casing 1 rotate in a sealing manner, and the inner space of the annular shell 81 and the water pumping pipe 72 are communicated with each other; two sides of the ring shell 81 are respectively provided with a second limiting ring 82, and the second limiting rings 82 are tightly attached to the side wall of the ring shell 81 and fixedly connected with the outer peripheral surface of the shell 1, so that the stability of the ring shell 81 rotating on the outer peripheral surface of the shell 1 is guaranteed; the outer circumferential surface of the ring shell 81 can be further provided with two corrugated pipes 83, the two corrugated pipes 83 are abutted against each other, and one ends of the corrugated pipes 83 are fixed on the outer circumferential surface of the ring shell 81 and are communicated with the inner wall of the ring shell 81. When the staff placed the pipeline inner wall cleaning device in the pipeline, accessible ring shell 81's rotation made bellows 83 be located the bottom of casing 1, then through the extension of bellows 83 for the tip of bellows 83 is closer to the diapire of bellows 83 more. In-process at high pressure nozzle 41 to spray rinsing all around, two carousel 31 with most waste water gathering between two carousel 31, reduced splashing everywhere of waste water, liquid can gather in the bottom of pipeline under the action of gravity, prop up this moment and establish bellows 83 at the outer arm can in time with most waste water suction pipe 72 is advanced in the suction under the effect of pump body 732 suction to reduce the everywhere of free flowing of waste water, also timely to the pipeline inner wall cleared up.
As shown in fig. 5, a plurality of water leakage ports 811 are further formed on one side of the ring housing 81 away from the bellows 83 along the annular direction of the ring housing 81. Because high pressure nozzle 41's even laying for the sparge water can be abundant with the contact of pipeline inner wall, and final liquid can gather in the bottom of pipeline, and some liquid can gather in the bottom of pipeline along the radian of pipeline inner wall, and some liquid can directly drip downwards, and the seting up of the hole that leaks, the liquid that can be timely will drip downwards is collected, thereby has reduced the pressure that bellows 83 extracted.
As shown in fig. 5, the bellows 83 can freely adjust its length and rotation angle, and a positioning unit 9 for positioning the stretching position and rotation position of the bellows 83 is further provided on the outer peripheral surface of the bellows 83 in order to stably maintain the bellows 83 at an optimum extraction position. The positioning assembly 9 comprises a positioning sleeve 91 arranged at the fixed position of the corrugated pipe 83 and the annular shell 81, the positioning sleeve and the corrugated pipe 83 are coaxially arranged, and one end face of the positioning sleeve is fixedly connected to the annular shell 81; the other end of the positioning sleeve is coaxially and rotatably connected with a rotating pipe 92, the peripheral surface of the rotating pipe 92 is fixedly connected with two flexible positioning strips 93 through bolts, the port position of the corrugated pipe 83 is coaxially and rotatably connected with a positioning pipe 94, the peripheral surface of the positioning pipe 94 is fixedly connected with two containing rings 95, and the center of the two containing rings 95 is connected to pass through the middle point of the positioning pipe 94.
After the worker stretches and rotates the corrugated pipe 83, the rotating pipe 92 can be rotated, so that the two positioning strips 93 are respectively attached to the minimum intrados and the maximum intrados of the corrugated pipe 83 along the length direction of the corrugated pipe 83, then the other ends of the positioning strips 93 penetrate into the corresponding containing rings 95, and the outer walls of the containing rings 95 are in threaded connection with positioning bolts 96 which are abutted to the positioning strips 93. Finally, the worker can cut off the extra length of the positioning strip 93 to prevent the strip from being wound into the turntable 31. By screwing the positioning bolt 96, the slip of the receiving ring 95 and the positioning strip 93 is restricted, so that the positioning strip 93 is held in a corresponding bent state, thereby holding the bellows 83 in a corresponding tensile bending device. In the process of rotating the turntable 31, each corrugated pipe 83 can be kept in corresponding filling, the corrugated pipes 83 are not easy to be rolled into the gap between the turntable 31 and the pipeline, and the normal extraction of waste water from the port of the corrugated pipe 83 in the moving process of the shell 1 is ensured.
As shown in fig. 1, a pulling rope 6 is fixedly connected to one side of the cover 12 away from the housing 1, and when the driving motor 52 and the water pump work, a worker can slowly pull the pulling rope 6, so as to drive the housing 1 to advance in the pipeline at a constant speed, and efficiently clean the inner wall of the pipeline, thereby reducing the labor consumption of the worker.
The above embodiments are preferred embodiments of the present application, and the protection scope of the present application is not limited by the above embodiments, so: all equivalent changes made according to the structure, shape and principle of the present application shall be covered by the protection scope of the present application.
