Technical Field

[0002] At present, drainage pipes are mainly used to drain rainwater, sewage, farmland irrigation, etc. When drainage pipes are used to transport high-pressure fluids, the compressive strength of the drainage pipes needs to be considered. In order to enhance the compressive strength of the drainage pipes, steel wire springs are usually installed in the pipes of the drainage pipes to enhance their compressive strength.

[0003] Such as the patent application number CN202221047548.8, a pressure-resistant plastic drain pipe, in particular, it relates to a pressure-resistant plastic drain pipe. An outer reinforcing sleeve is provided on the outside of the plastic drain pipe, and several supporting beams are provided on the outside of the outer reinforcing sleeve, and a soft rubber buffer tube is provided on the outside of the outer reinforcing sleeve, and several buffer shrinkage bags are staggered inside the soft rubber buffer tube; wherein, the supporting beam is composed of a fixed seat and a supporting beam, and the fixed seat rotates the supporting beam on the surface of the outer reinforcing sleeve, and the supporting beam is wrapped on the outside of the outer reinforcing sleeve in a spiral structure, and the buffer shrinkage bags are evenly distributed between two adjacent groups of supporting beams. It adopts a protective buffer sleeve structure to perform pressure buffering on the drainage pipe, which increases the toughness of the protective layer while increasing the pressure resistance; in addition, the outer protective pressure-resistant sleeve can be recycled and reused, which greatly reduces the cost.

[0004] Although the above-mentioned compression-resistant plastic drain pipe has strong compression resistance, its sound-absorbing performance is poor and its compression resistance is insufficient when encountering pressure and impact generated from the inside. Utility Model Content

[0022] Specific embodiment 1: Please refer to Figure 1-6A compression-resistant spiral sound-absorbing drain pipe comprises a spiral drain pipe 10; six slide grooves 11 are fixedly arranged on the outer circumference of the spiral drain pipe 10; an outer sleeve 13 is slidably arranged on the outer side of the spiral drain pipe 10; it also includes a slider 16 fixedly arranged on the inner side of the outer sleeve 13; the number of the sliders 16 is sixteen; one end of the inner side of the slider 16 abuts against the slide groove 11; a sound-absorbing cotton 12 is embedded between two adjacent sliders 16; sixteen stiffening ribs 14 are fixedly arranged on the outer circumference of the outer sleeve 13; a shock-absorbing cotton 15 is embedded between two of the stiffening ribs 14; a rubber sleeve 17 is sleeved on the outer side of the outer sleeve 13; the inner side of the slider 16 is slidably connected to the slide groove 11, so that the spiral drain pipe 10 is tightly connected to the outer sleeve 13, and the stiffening ribs 14 and the outer sleeve 13 are used to enhance the compression resistance of the spiral drain pipe 10; the sound-absorbing cotton 12 and the shock-absorbing cotton 15 are provided to enhance the compression resistance of the spiral drain pipe 10 and also enhance the sound-absorbing ability.

[0023] See also Figure 1 A shock absorbing layer 18 is sleeved on the outer side of the rubber sleeve 17; and a rubber sleeve 2 19 is sleeved on the outer side of the shock absorbing layer 18.

[0024] See also Figure 4 The rubber sleeve 17 is made of wear-resistant and highly elastic rubber.

[0025] See also Figure 1-2 The shock absorbing layer 18 is formed by pressing multiple layers of high elastic sponge net.

[0026] See also Figure 4 The rubber sleeve 19 is made of high-elastic rubber material; by arranging the rubber sleeve 17 and the rubber sleeve 19, the pressure resistance of the drainage pipe is enhanced; the shock-absorbing layer 18 is used to enhance the energy of the spiral drainage pipe 10 to absorb noise, and the pressure resistance of the shock-absorbing layer 18 is also enhanced. At the same time, the shock-absorbing layer 18, the rubber sleeve 17, and the rubber sleeve 19 are used to reduce the deformation of the spiral drainage pipe 10 and the outer sleeve 13 due to the internal pressure and impact.

[0027] See also Figure 1 , Figure 3 and Figure 5 The upper end of the slider 16 corresponds to the upper end of the stiffening rib 14 .

[0028] Before use, align the slider 16 on the outer sleeve 13 with the slide groove 11 on the spiral drain pipe 10, insert multiple pieces of sound-absorbing cotton 12 between two separated sliders 16, then rotate and lower the outer sleeve 13 so that the outer sleeve 13 and the spiral drain pipe 10 are clamped with each other, then insert multiple pieces of shock-absorbing cotton 15 between two adjacent stiffening ribs 14, then sleeve the rubber sleeve 17 on the outside of the outer sleeve 13, then sleeve the shock-absorbing layer 18 on the outside of the rubber sleeve 17, and then sleeve the rubber sleeve 2 19 on the outside of the shock-absorbing layer 18;

[0029] After the water flows into the inner side of the spiral drain pipe 10, the water flows along the spiral lines on the inner side of the spiral drain pipe 10, and the noise generated by the impact of the water on the pipe wall cancels each other out along with the water flow. The impact of the water on the spiral drain pipe 10 is absorbed by the sound-absorbing cotton 12 and the shock-absorbing cotton 15. If foreign matter is mixed in the water flow and impacts the spiral drain pipe 10, the impact force is first dispersed to the rubber sleeve 17 through the stiffening ribs 14. The rubber sleeve 17 is subjected to the impact force and squeezes the shock-absorbing layer 18. After being squeezed, the shock-absorbing layer 18 squeezes the rubber sleeve 2 19 again. When the impact dissipates, the rubber sleeve 2 19 begins to recover under the action of elastic force, and the shock-absorbing layer 18 also returns to its original position, thereby enhancing the spiral drain pipe 10 to resist the pressure inside.
