[0025] The surface of the mounting shaft 5 is slidably connected with a movable sleeve 3, the inner wall of the mounting tube 1 is fixedly connected with a second fixing frame 17, the movable sleeve 3 penetrates the surface of the second fixing frame 17 and is slidably connected with the inside of the second fixing frame 17, and then through the arrangement of the first fixing frame 4 and the second fixing frame 17, the two ends of the structure in the mounting tube 1 can be erected, thereby avoiding the situation in which the device generates large vibrations during purging, thereby affecting the structural strength of the device.

[0026] The surface of the movable sleeve 3 is slidably connected with a fixed seat 6, and the fixed seat 6 and the movable sleeve 3 can be connected by a spline shaft, so as to ensure that the fixed seat 6 can drive the movable sleeve 3 to rotate without affecting the mutual sliding between the movable sleeve 3 and the fixed seat 6, and the fixed seat 6 is rotatably connected to the surface of the second fixed frame 17, and the surface of the fixed seat 6 is fixedly connected with a turbine blade 7, so that through the setting of the turbine blade 7, the wind force generated when the device is blown can be utilized to provide a certain power source for the operation of the device, which has a high energy-saving effect.

[0027] Furthermore, three conical plates 9 are provided on the surface of the movable sleeve 3 away from the first fixed frame 4, and the structures on the three conical plates 9 are the same. A conical insertion block 10 is provided at one end of the movable sleeve 3 away from the first fixed frame 4, and the surfaces of the conical plates 9 and the insertion blocks 10 are both provided with threads 8. Through the setting of the threads 8, the conical plates 9 and the insertion blocks 10 can drill through the polyurethane foam sealant more easily, thereby improving the efficiency of the device in clearing pipe blockages.

[0028] A spiral groove 15 is provided on the surface of the mounting shaft 5, a fixed rod 16 is fixedly connected to the inner wall of the movable sleeve 3, the surface of the fixed rod 16 is slidably connected to the inner wall of the spiral groove 15, a slide groove 13 is provided on the surface of the movable sleeve 3, a movable plate 14 is slidably connected to the inner wall of the slide groove 13, a connecting rod 11 is rotatably connected to the surface of the movable plate 14, one end of the connecting rod 11 away from the movable plate 14 is rotatably connected to the inner side of the conical plate 9, a telescopic rod 12 is fixedly connected to the inner side of the conical plate 9, one end of the telescopic rod 12 away from the conical plate 9 is fixedly connected to the surface of the movable sleeve 3, for guiding the movement of the conical plate 9, the telescopic rod 12 includes a telescopic inner rod and a telescopic outer rod, the surface of the telescopic inner rod can slide relative to the inside of the telescopic outer rod, thereby realizing the telescopic rod 12.

[0029] Furthermore, a threaded rod 18 with a "stem"-shaped cross section is fixedly connected to one end of the insertion block 10 close to the movable sleeve 3. The surface of the threaded rod 18 is connected to the internal thread of the movable sleeve 3, and the surface of the movable plate 14 is in contact with the surface of the threaded rod 18. At the same time, the "stem"-shaped setting of the threaded rod 18 ensures the movement of the threaded rod 18, and can smoothly drive the movable plate 14 to slide in the slide groove 13, thereby ensuring the smooth operation of the device.

[0030] When clearing the blockage, the flange 2 near the thread 8 and one end of the insert block 10 is connected to the pipe to be cleared, and the flange 2 at the other end of the device is connected to the air compressor, so that air can circulate inside the device, thereby generating a blowing force to clean the inside of the pipe to be cleared. When the air compressor blows the inside of the device, the wind acts on the turbine blades 7, thereby driving the turbine blades 7 to rotate, and drives the movable sleeve 3 to rotate through the fixed seat 6, thereby driving the fixed rod 16 to slide in the spiral groove 15. Since the spiral groove 15 is spirally arranged, the movable sleeve 3 gradually slides in the mounting tube 1 while rotating, thereby driving the insert block 10 and the conical plate 9 to rotate and gradually move toward the pipe to be cleared, so that as the conical plate 9 and the insert block 10 move, the polyurethane foam sealant in the pipe is drilled and penetrated.

[0031] Then the air compressor is stopped. At this time, the insertion block 10 penetrates the polyurethane foam sealant and is exposed to the outside world. Then the insertion block 10 is rotated, so that the threaded rod 18 pulls the movable plate 14, thereby driving the connecting rod 11 from an inclined state to a vertical state, and then the conical plate 9 is pushed up to expand the conical plate 9 outward, so that the conical plate 9 gradually fits with the inner wall of the pipeline to be cleaned, and then the vacuum pump is replaced at this time, thereby driving the turbine blades 7 to reverse, thereby driving the movable sleeve 3 to reverse, so that the movable sleeve 3 is gradually pulled out of the pipeline to be cleaned, and then The conical plate 9 is driven to rotate and be drawn out from the pipe to be cleaned, and then the inner wall of the pipe to be cleaned is scraped, so that the residual polyurethane foam sealant is cleaned again, and the negative pressure generated by the vacuum pump is used to absorb the fallen polyurethane foam sealant to complete the purging of the pipe to be cleaned, so that the blowing force and suction force can be used to drive the conical plate 9 and the insertion block 10 to rotate to clean the polyurethane foam sealant in the pipe to be cleaned, thereby solving the problem that the filling pipe of the polyurethane foam sealant is thin and difficult to clear, and has a high promotion value.

[0032] Secondly, when the fixed rod 16 rotates to the tail end of the spiral groove 15, if the movable sleeve 3 continues to rotate at this time, since the fixed rod 16 cannot continue to slide in the spiral groove 15, the movable sleeve 3 will drive the installation shaft 5 to rotate synchronously without affecting the normal operation of the device.

[0033] Working principle: When clearing a blockage, connect the flange 2 near the thread 8 and one end of the insertion block 10 to the pipe to be cleared, and then connect the flange 2 at the other end to the air compressor. The air compressor generates a blowing force to act on the turbine blades 7, driving the turbine blades 7 to rotate, driving the insertion block 10 and the conical plate 9 to rotate while gradually moving toward the pipe to be cleared, drilling and penetrating the polyurethane foam sealant in the pipe, then stop the air compressor, rotate the insertion block 10, so that the conical plate 9 gradually fits the inner wall of the pipe to be cleared, and then replace the air compressor with a vacuum pump, drive the turbine blades 7 to reverse, so that the movable sleeve 3 is gradually pulled out of the pipe to be cleared, and drive the conical plate 9 to rotate and pull it out of the pipe to be cleared, scrape the inner wall of the pipe to be cleared, and clean the residual polyurethane foam sealant again.

[0034] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments. Various changes can be made within the knowledge scope of ordinary technicians in the technical field without departing from the purpose of the present invention.
