DETAILED DESCRIPTION

[0028] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0029] Embodiment 1: Figure 1 , Figure 2 and Figure 3As shown, the embodiment of the present invention includes an arc-shaped shovel plate 1, a connecting spring 2 is fixedly installed on the back side of the arc-shaped shovel plate 1, a capsule 3 is fixedly installed on the side of the connecting spring 2 away from the arc-shaped shovel plate 1, a stepped end 301 is provided in the middle of the inner arc surface of the capsule 3, one end of the connecting spring 2 away from the arc-shaped shovel plate 1 is fixedly installed on the surface of the stepped end 301, an arc-shaped groove 303 is provided on the side of the inner arc surface of the capsule 3 close to the stepped end 301, an inner arc surface of the arc groove 303 is movably sleeved with an inner flushing plate 4, the inner flushing plate 4, a through hole is provided in the middle of one side surface of the inner flushing plate 4, a sleeve 5 is connected through the through hole of the inner flushing plate 4, a C-shaped connecting part 6 is provided at the top of the outer arc surface of the sleeve 5, concave grooves are provided on both sides of the C-shaped connecting part 6, outer sealing strip plates 7 are movably connected on both sides of the C-shaped connecting part 6, a rubber plate 8 is connected to the bottom of the outer arc surface of the sleeve 5, and a concave hole 9 is provided on the outer arc surface of the capsule 3.

[0030] The arc-shaped shovel plate 1 is a push shovel with a certain thickness. The shovel surface is an arc-shaped opening facing forward. The bottom surface of the arc-shaped shovel plate 1 is an arc-shaped that matches the inner surface of the tube. The thrust of the arc-shaped shovel plate 1 is transmitted to the capsule 3 at the rear end. The connecting spring 2 at the rear end enables the arc-shaped shovel plate 1 to be axially advanced and to float slightly in the radial direction. A hollow spherical capsule 3 is used at the rear end. The inside of the capsule 3 passes through a channel for the entry and exit of gas or liquid. Before the installation is completed, the inside can be filled with water or air. After inflation or filling with water, the capsule 3 strengthens the supporting force of the cleaning device body, so that the cleaning device can have better strength and toughness. Filling the capsule 3 with water can accelerate the dissolution of the capsule 3 from the early stage of the cleaning stage, but the dissolution time of the capsule 3 needs to be better controlled to prevent the capsule 3 from being damaged, resulting in a decrease in the overall structural strength of the cleaning device.

[0031] The arc-shaped shovel plate 1 usually has a certain hardness and sharpness, and can effectively scrape off stubborn dirt and sediment on the inner wall of the pipe. Whether it is hard-shell scale, sticky oil or accumulation of solid particles, the scraper can effectively peel it off the pipe wall. The capsule 3 has a soft texture and good water absorption. After the scraper scrapes off most of the dirt, the inner wall of the pipe can be carefully wiped. It can absorb residual sewage and tiny particles to make the inner wall of the pipe smoother and cleaner.

[0032] like Figure 2 , Figure 3 and Figure 7 As shown, there are several connecting springs 2, which are evenly distributed on the surface of the step end 301 in the form of a ring array, a sealing kit 10 is movably sleeved on one side of the inner arc surface of the sleeve 5, a through hole is provided on one side of the sealing kit 10, and the through hole on one side of the sealing kit 10 is adapted to the sleeve 5, and a stator cleaning nozzle 11 is movably connected to the outer arc surface of the sealing kit 10, and a spray hole 12 is provided on the outer arc surface of the stator cleaning nozzle 11.

[0033] One end of the stator cleaning nozzle 11 is sleeved into the arc-shaped shovel plate 1, and a protective sleeve 13 is provided in the middle of the inner arc surface of the sleeve connection tube 5. An outer convex end 14 is provided at the bottom of the inner arc surface of the protective sleeve 13. The outer convex end 14 is connected to the inside of the protective sleeve 13 in an annular structure. A rotating shaft 15 is movably connected to the outer arc surface of the outer convex end 14. A propulsion nozzle 16 is movably connected to one side of the rotating shaft 15. One end of the propulsion nozzle 16 is close to the inner arc surface of the stator cleaning nozzle 11. The interior of the stator cleaning nozzle 11 is a hollow structure. The protective sleeve 13 and The stator cleaning nozzle 11 is in the same plane, and a fixed flange 17 is connected to one side of the stator cleaning nozzle 11. One end of the fixed flange 17 is fixedly connected to the sleeve 5. The inner arc surface of the rubber plate 8 is provided with a serrated portion. The outer arc surface of the protective sleeve 13 is connected and adapted to the serrated portion on the rubber plate 8. The outer arc surface of the arc shovel plate 1 is provided with an arc guide surface 101. The inner arc surface of the arc shovel plate 1 is connected with the capsule 3. The stepped end 301 inside the capsule 3 is an annular structure, and the stator cleaning nozzle 11 is a conical structure.

[0034] During operation, the cleaning fluid enters the channel or pipeline and then is loaded onto the nozzle module. The rotating shaft 15 is responsible for linearly pushing the pipeline cleaning with the aid of the propulsion nozzle 16. Here, the cleaning fluid enters the stator cleaning nozzle 11 through the high-pressure pipeline interface, which additionally provides a cleaning jet radially outward from the spray hole 12. The rotating shaft 15 guides the liquid jet along the inner wall of the pipeline or channel and leaves the stator cleaning nozzle 11, thereby achieving streak-free cleaning of the inner wall.

[0035] A plurality of spray holes 12 are provided on the stator cleaning nozzle 11, which promote the rotation of the stator cleaning nozzle 11, so that when the exiting fluid is loaded with pressure, the propulsion nozzle 16 can be rotated around the rotating shaft 15 at a high speed. In addition, the stator cleaning nozzle 11 releases a cleaning beam, which impacts the inner wall of the channel or pipe at different angles and has different cleaning nozzle angles, thereby achieving a maximum cleaning effect and achieving streak-free cleaning of the inner wall.

[0036] The rotating propulsion nozzle 16 water column will generate centrifugal force during the movement, which greatly enhances the impact force of the water column. When this rotating water column with strong impact force acts on the inner wall of the pipe, it can effectively wash away stubborn dirt, sediment, rust and other impurities attached to the inner wall of the pipe. In addition, the rotating stator cleaning nozzle 11 water column exerts relatively uniform force on the inner wall of the pipe during the cleaning process. Unlike the traditional high-pressure linear water column that may cause excessive impact on local parts of the pipe, the spiral motion of the rotating water column makes its force more evenly distributed on the inner wall of the pipe, reducing the risk of pipeline damage due to excessive local force.

[0037] like Figure 1 and Figure 6As shown, the outer arc surface of the sleeve 5 is movably sleeved with an inner double-conical sleeve 18, and the outer arc surface of the inner double-conical sleeve 18 is movably sleeved with an outer double-conical sleeve 19. The outer arc surface of the outer double-conical sleeve 19 is fixedly installed with a roller 20 by bolts, and the top of the roller 20 is connected with a guard plate 21. The roller 20 is fixedly connected to the outer double-conical sleeve 19 through the guard plate 21. The number of rollers 20 is several, and they are evenly distributed on the surface of the outer double-conical sleeve 19 in the form of a ring array. An accelerating air duct 22 is provided between the outer double-conical sleeve 19 and the inner double-conical sleeve 18, and the accelerating air duct 22 is placed at the rear end of the capsule 3. Several rollers 20 and the capsule 3 are all fitted on the inner wall of the pipe.

[0038] In this embodiment, in order to prevent the surface of the device body from colliding or getting stuck with the inner wall of the pipe when turning, the outermost edge of the roller 20 rolls along the inner wall of the pipe under the action of traction, driving the device to move together, and the outer wall of the outer double-cone sleeve 19 gradually increases in the radial direction and the inner wall of the inner double-cone sleeve 18 form an accelerating air duct 22 with a gradually reduced cross-section, and the outlet of the accelerating air duct 22 faces the inner wall of the pipe. When the airflow passes through the accelerating air duct 22, due to the structural design of its gradually reduced cross-section, the airflow reaches the fastest speed at the smallest cross-section of the accelerating air duct 22, and the dust accumulated on the inner wall of the pipe is blown away by the airflow from the accelerating air duct 22, in order to ensure the stability of the device operation.

[0039] The roller 20 can roll forward quickly in the pipeline. Compared with the slow manual cleaning method, it can cover a larger pipeline area in a shorter time, which greatly improves the efficiency of the cleaning work and reduces the time of production interruption.

[0040] Embodiment 2: Figures 1 to 7 As shown in Comparative Example 1, another embodiment of the present invention is:

[0041] Working principle: During operation, the cleaning fluid enters the channel or pipeline, and then the cleaning fluid is loaded into the nozzle module. The rotating shaft 15 is responsible for linearly pushing the pipeline cleaning with the help of the propulsion nozzle 16. Here, the cleaning fluid enters the stator cleaning nozzle 11 through the high-pressure pipeline interface, which additionally provides a cleaning beam radially outward from the spray hole 12. Through the rotating shaft 15, the liquid jet is guided along the inner wall of the pipeline or channel to leave the stator cleaning nozzle 11, thereby achieving streak-free cleaning of the inner wall. The cleaning fluid enters the channel or pipeline, and then the cleaning fluid is loaded into the nozzle module. The rotating shaft 15 is responsible for linearly pushing the nozzle 16 with the help of the propulsion nozzle 16. Dynamic pipeline cleaning, here, the cleaning fluid enters the stator cleaning nozzle 11 through the high-pressure pipeline interface, which additionally provides a cleaning beam radially outward from the spray hole 12. Through the rotating shaft 15, the liquid beam is guided along the inner wall of the pipeline or channel to leave the stator cleaning nozzle 11, thereby achieving streak-free cleaning of the inner wall. Under the action of traction, the outermost edge of the roller 20 rolls along the inner wall of the pipeline, driving the device to move together. The outer wall of the outer double-cone sleeve 19 gradually increases in the radial direction and the inner wall of the inner double-cone sleeve 18 form an acceleration duct 22 with a gradually reduced cross-section. The outlet of the acceleration duct 22 faces the inner wall of the pipeline. When the airflow passes through the acceleration duct 22, due to its gradually reduced cross-section structural design, the airflow reaches the fastest speed at the smallest cross-section of the acceleration duct 22, and the dust accumulated on the inner wall 3 of the pipeline is blown up by the acceleration duct 22, in order to ensure the stability of the device operation.
