[0002] At present, pipelines are devices connected by pipes, pipe connectors and valves for conveying gas, liquid or fluid with solid particles.

[0027] like Figure 2 As shown, in this embodiment, two movable grooves 21 are provided on the outer peripheral wall of the blocking inner tube 20. Of course, the movable grooves 21 may also be one or three or other numbers. The number of the movable grooves 21 is not limited in this embodiment.

[0028] It should be noted that the number of the card slots 11 and the slideways 24 is substantially the same as the number of the moving slots 21 .

[0029] When the blocking inner tube 20 is inserted into the connecting inner tube 10, the end of the blocking block 212 away from the adjusting plate 213 is inserted into the slot 11, and the return spring 211 is in a naturally extended state; when the blocking inner tube 20 is pulled out of the connecting inner tube 10, pressure is applied to the protruding end of the adjusting plate 213, and the adjusting plate 213 drives the blocking block 212 to slide along the moving slot 21 until the blocking block 212 slides out of the slot 11, and the blocking inner tube 20 is separated from the connecting inner tube 10, so that the interior of the blocking inner tube 20 can be cleaned.

[0030] Furthermore, in this embodiment, the cleaning assembly includes a plurality of cleaning units 40, and the plurality of cleaning units 40 are arranged at intervals along the center line direction of the blocking inner tube 20; a plurality of rotating grooves 22 are opened on the inner circumferential wall of the blocking inner tube 20, and the rotating grooves 22 are arranged one by one corresponding to the cleaning units 40, and the first end of the cleaning unit 40 is arranged in the rotating groove 22; when the cleaning unit 40 blocks impurities and garbage in the water flow, the second end of the cleaning unit 40 extends to the outside of the rotating groove 22 to block impurities and garbage in the water flow.

[0031] It should be noted that the number of the rotating grooves 22 is substantially the same as the number of the cleaning units 40 .

[0032] Continue to refer to Figures 3 to 5 In this embodiment, the cleaning unit 40 includes a connecting spring 41 and a rotating plate 42, one end of the connecting spring 41 is connected to the inner bottom surface of the rotating groove 22, the other end of the connecting spring 41 is connected to the outer wall of one end close to the rotating plate 42, and the end of the rotating plate 42 away from the connecting spring 41 is rotatably connected to the inner wall of the rotating groove 22 through a rotating shaft, and the rotating plate 42 can relatively block the inner tube 20 from rotating; when blocking impurities and garbage in the water flow, the connecting spring 41 is in a naturally extended state, and the end of the rotating plate 42 away from the rotating shaft extends to the outside of the rotating groove 22.

[0033] Specifically, the center line of the connecting spring 41 is arranged parallel to the radial direction of the blocking inner tube 20 .

[0034] During use, when water flows through the interior of the blocking inner tube 20, impurities and garbage in the water flow are blocked by the rotating plate 42. When cleaning the garbage and impurities after blocking, pressure is applied to the protruding end of the adjusting plate 213, and the adjusting plate 213 drives the blocking block 212 to slide along the moving groove 21 until the blocking block 212 slides out of the slot 11, thereby moving the blocking inner tube 20 out of the connecting inner tube 10, and a tool matching the interior of the blocking inner tube 20 is inserted into the interior of the blocking inner tube 20. The outer wall of the tool squeezes the rotating plate 42 so that the rotating plate 42 rotates to the inner wall of the blocking inner tube 20, and the tool pushes out the impurities and garbage blocked by the rotating plate 42. At this time, the connecting spring 41 is in a compressed state. After cleaning is completed, the rotating plate 42 is pushed to reset by the restoring force of the connecting spring 41.

[0035] Exemplarily, the rotating plate 42 may be wedge-shaped. Of course, the rotating plate 42 may also be trapezoidal. In the implementation mode in which the rotating plate 42 is wedge-shaped, one side close to the tip of the rotating plate 42 is connected to one end of the connecting spring 41.

[0036] Furthermore, the cleaning unit 40 also includes a blocking frame 43, which is arranged on the side of the rotating plate 42 away from the connecting spring 41, and the blocking frame 43 is located in the rotating groove 22. The blocking frame 43 is provided with a blocking groove on the side facing the rotating plate 42 for blocking the rotating plate 42 from rotating toward the moving groove 21. The end of the rotating plate 42 away from the connecting spring 41 is inserted into the blocking groove, and the rotating plate 42 can rotate in the blocking groove. Such a configuration reduces the possibility of internal blockage of the high-pressure resistant pipeline 1 due to long-term use.

[0037] Continue to refer to Figures 1 to 3 In this embodiment, the buffer assembly 30 includes a high-pressure resistant inner tube 31 and a buffer unit 32. The high-pressure resistant inner tube 31 is sleeved on the outer peripheral wall of the connecting inner tube 10, and the buffer unit 32 is sleeved on the outer peripheral wall of the high-pressure resistant inner tube 31.

[0038] Specifically, the center line of the high-pressure resistant inner tube 31 is arranged in parallel with the center line of the connecting inner tube 10 . In some practicable embodiments, the center line of the high-pressure resistant inner tube 31 is arranged in a colinear relationship with the center line of the connecting inner tube 10 .

[0039] Furthermore, in this embodiment, the buffer unit 32 includes an outer tube 321 and a plurality of buffer modules 322. The outer tube 321 is sleeved on the outer peripheral wall of the high-pressure resistant inner tube 31. A plurality of damping grooves 3211 are opened on the outer peripheral wall of the outer tube 321. The plurality of damping grooves 3211 extend along the center line direction of the outer tube 321. The plurality of damping grooves 3211 are arranged at circumferential intervals around the outer tube 321. The damping grooves 3211 and the buffer modules 322 are arranged one by one. One ends of the plurality of buffer modules 322 are respectively arranged in the damping grooves 3211, and the other ends of the plurality of buffer modules 322 extend to the outside of the damping grooves 3211.

[0040] Specifically, the high-pressure resistant inner tube 31 is located between the outer tube 321 and the connecting inner tube 10 .

[0041] It should be noted that the number of the damping grooves 3211 is substantially the same as the number of the buffer modules 322 .

[0042] Furthermore, in this embodiment, the buffer module 322 includes a damping block 3221, a rubber cover 3222 and a plurality of buffer springs 3223, the plurality of buffer springs 3223 are all arranged in one of the damping grooves 3211, the plurality of buffer springs 3223 are arranged at intervals along the extension direction of the damping groove 3211, one end of the plurality of buffer springs 3223 are all connected to the inner bottom surface of the damping groove 3211, the other ends of the plurality of buffer springs 3223 are all connected to the damping block 3221, and the damping block 3221 extends along the length direction of the damping groove 3211, and the rubber cover 3222 is covered on the end of the damping block 3221 away from the buffer spring 3223.

By setting the rubber cover 3222, the outer wall of the high-pressure resistant pipe 1 is prevented from being worn and damaged when the high-pressure resistant pipe 1 is placed and transported.

[0043] When the high-pressure resistant pipe 1 is transported and placed, when the outer walls of the high-pressure resistant pipe 1 contact and collide with each other, the rubber covers 3222 collide with each other first, and the wear resistance is increased by the rubber covers 3222. When the outer wall of the rubber covers 3222 is collided, the damping block 3221 squeezes the buffer spring 3223, and the buffer spring 3223 buffers the collision force.

[0044] Exemplarily, the rubber cover 3222 may be in the shape of a hollow trapezoid. Of course, the rubber cover 3222 may also be in the shape of a hollow hemisphere.

[0045] In order to prevent the blocking inner tube 20 from rotating relative to the connecting inner tube 10, at least one blocking block 23 is provided on the outer circumferential wall near one end of the blocking inner tube 20, and at least one fixing groove matched with the blocking block 23 is opened on the inner circumferential wall near one end of the connecting inner tube 10, and the fixing groove and the blocking block 23 are arranged correspondingly; when the blocking inner tube 20 is inserted into the connecting inner tube 10, the blocking block 23 is inserted into the fixing groove.

[0046] Specifically, a blocking block 23 is provided on the outer circumferential wall of the end of the blocking inner tube 20 away from the movable groove 21, and the blocking block 23 extends outward along the radial direction of the blocking inner tube 20. An inwardly recessed fixing groove is provided on the inner circumferential wall of the end of the connecting inner tube 10 away from the fixing groove 11, and the side of the fixing groove away from the fixing groove 11 is open to facilitate the blocking block 23 to slide in or out of the fixing groove.

[0048] It should be noted that the number of the clamping blocks 23 is substantially the same as the number of the fixing slots.

[0049] The use process of the high-pressure resistant pipe 1 provided in this embodiment is as follows: when water flows through the interior of the blocking inner tube 20, impurities and garbage in the water flow are blocked by the rotating plate 42. When cleaning the garbage and impurities after blocking, pressure is applied to the protruding end of the adjusting plate 213, and the adjusting plate 213 drives the blocking block 212 to slide along the moving groove 21 until the blocking block 212 slides out of the card groove 11, thereby moving the blocking inner tube 20 out of the connecting inner tube 10, and using a tool matching the interior of the blocking inner tube 20 to insert into the interior of the blocking inner tube 20, the outer wall of the tool squeezes the rotating plate 42 so that the rotating plate 42 rotates to the inner wall of the blocking inner tube 20, and at the same time, the tool pushes out the impurities and garbage blocked by the rotating plate 42. At this time, the connecting spring 41 is in a compressed state. After cleaning is completed, the rotating plate 42 is pushed to reset by the restoring force of the connecting spring 41.
