Description

Technical Field

[0001] The utility model relates to the technical field of pipes, in particular to a fully-clad enhanced corrugated pipe. Background Art

[0002] Traditional corrugated pipes mainly achieve a certain degree of flexibility and scalability through their unique corrugated structure design. In some practical applications of corrugated pipes, the corrugated pipes will be subjected to external pressure. For example, the corrugated pipes buried underground will directly bear the pressure of the soil layer. When these corrugated pipes are subjected to external pressure loads for a long time, they are prone to serious deformation or even rupture, which will lead to leakage of materials in the corrugated pipes and damage to internal cables, causing great economic losses. Summary of the invention

[0003] The utility model aims to solve the deficiencies in the prior art and provide a fully covered enhanced corrugated pipe.

[0004] The purpose of the utility model is achieved through the following technical solutions: a fully covered reinforced bellows, comprising a bellows body and a pressure-resistant reinforcement ring, the bellows is provided with a crest portion and a trough portion, the pressure-resistant reinforcement ring is arranged on the inner side of the crest portion; the pressure-resistant reinforcement ring comprises a ring body made of elastic material, the ring body is provided with a pre-stressing mechanism; a covering layer is provided on the outer side of the bellows body.

[0005] In the utility model, a pressure-resistant reinforcement ring is arranged on the inner side of the crest part, which can greatly enhance the radial pressure resistance of the bellows and reduce the risk of serious deformation or even rupture of the bellows when subjected to external pressure, thereby reducing the risk of leakage of materials in the bellows and damage to internal cables.

[0006] Preferably, a notch is provided on the ring body, and the pre-stressing mechanism includes a restraining part and an elastomer made of elastic material, the elastomer is in a "U" shape, and the two ends of the elastomer are respectively connected to the two ends of the ring body; limiting grooves are respectively provided on both sides of the elastomer; the restraining part is in a "U" shape; when the compression reinforcement ring is in a pre-stressing state, the two ends of the restraining part are respectively inserted into the limiting grooves on both sides of the elastomer. When installing the pressure-resistant reinforcement ring, the two ends of the constraint can be first inserted into the limit grooves on both sides of the elastomer. At this time, the elastomer is in a compressed state, and the distance between the two ends of the elastomer reaches a smaller state, so that the width of the gap on the ring body reaches a smaller state, and then the diameter of the ring body reaches a smaller state. At this time, the pressure-resistant reinforcement ring is in a pre-stressed state, and the pressure-resistant reinforcement ring in the pre-stressed state can freely pass through the space inside the bellows; when the pressure-resistant reinforcement ring reaches the installation position (that is, the pressure-resistant reinforcement ring is located on the inner side of one of the wave peaks), the constraint is pulled out from the elastomer. After the constraint is pulled out, the constraint of the constraint on the elastomer is released, and the elastomer will return to its original shape, so that the two ends of the elastomer are opened, thereby increasing the width of the gap on the ring body, thereby increasing the diameter of the ring body, until the ring body and the inner surface of the wave peak are expanded, thereby completing the installation of the pressure-resistant reinforcement ring.

[0007] Preferably, the ring body is made of spring steel.

[0008] Preferably, the elastic body is made of spring steel.

[0009] Preferably, a pull ring is provided on the restraining member.

[0010] Preferably, the cross section of the ring body is arc-shaped.

[0011] Preferably, the coating layer is made of rubber.

[0012] The beneficial effect of the utility model is: in the utility model, by arranging a pressure-resistant reinforcement ring on the inner side of the crest part, the pressure-resistant reinforcement ring can greatly enhance the radial pressure resistance of the corrugated pipe, reduce the risk of serious deformation or even rupture of the corrugated pipe when subjected to external pressure, thereby reducing the risk of leakage of materials in the corrugated pipe and damage to internal cables.

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field belong to the scope of protection of the utility model.

[0020] like Figures 1 to 5 As shown, the fully covered reinforced corrugated pipe comprises a corrugated pipe body 1 and a compression reinforcement ring. The corrugated pipe is provided with a crest portion 2 and a trough portion 3. The crest portion 2 and the trough portion 3 are arranged in sequence and spaced apart, so that the corrugated pipe body 1 is in a corrugated structure as a whole. The compression reinforcement ring is arranged on the inner side of the crest portion 2.

[0021] In the utility model, by arranging a pressure-resistant reinforcement ring on the inner side of the crest part 2, the pressure-resistant reinforcement ring can greatly enhance the radial pressure resistance of the bellows, reduce the risk of serious deformation or even rupture of the bellows when subjected to external pressure, thereby reducing the risk of leakage of materials in the bellows and damage to internal cables.

[0022] The density of the compression reinforcement rings can be selected according to actual needs. One compression reinforcement ring can be set inside each crest 2, or one compression reinforcement ring can be set every other crest 2. The greater the density of the compression reinforcement rings, the better the overall compression resistance of the bellows.

[0023] Specifically, the compression reinforcement ring includes a ring body 4 made of elastic material, and the cross section of the ring body 4 is in the shape of an arc. A pre-stressing mechanism is provided on the ring body 4. A notch is provided on the ring body 4. The pre-stressing mechanism includes an elastic body 5 and a restraining member 6 made of elastic material, and the elastic body 5 is in a "U" shape. The two ends of the elastic body 5 are respectively connected to the two ends of the ring body 4, and the elastic body 5 and the ring body 4 can be connected by welding. Limiting grooves 9 are respectively provided on both sides of the elastic body 5. In this embodiment, the ring body 4 and the elastic body 5 are both made of spring steel.

[0024] The restraint member 6 is in a "U" shape. The restraint member 6 is made of hard alloy, has high strength and is not easily deformed. When the compression reinforcement ring is in a pre-compression state, the two ends of the restraint member 6 are respectively inserted into the limit grooves 9 on both sides of the elastic body 5.

[0025] When installing the pressure-resistant reinforcing ring, the two ends of the restraining member 6 can be first inserted into the limit grooves on both sides of the elastic body 5. At this time, the elastic body 5 is in a compressed state, and the distance between the two ends of the elastic body 5 reaches a smaller state, so that the width of the gap on the ring body 4 reaches a smaller state, and then the diameter of the ring body 4 reaches a smaller state. At this time, the pressure-resistant reinforcing ring is in a pre-stressed state, and the pressure-resistant reinforcing ring in the pre-stressed state can freely pass through the space inside the corrugated tube; when the pressure-resistant reinforcing ring reaches the installation position (that is, the pressure-resistant reinforcing ring is located on the inner side of one of the wave peaks 2), the restraining member 6 is pulled out from the elastomer 5. After the restraining member 6 is pulled out, the restraint of the restraining member 6 on the elastomer 5 is released, and the elastomer 5 will return to its original shape, so that the two ends of the elastomer 5 are opened, thereby increasing the width of the gap on the ring body 4, thereby increasing the diameter of the ring body 4, until the ring body 4 and the inner surface of the wave peak 2 are expanded, thereby completing the installation of the pressure-resistant reinforcing ring.

[0026] Furthermore, a pull ring 7 is provided on the restraining member 6. By providing the pull ring 7 on the restraining member 6, it is convenient to remove the restraining member 6 from the elastic body 5.

[0027] The outer side of the corrugated tube body 1 is provided with a coating layer 8. In this embodiment, the coating layer 8 is made of rubber.

[0028] The present utility model is not limited to the above-mentioned optimal implementation mode. Anyone can derive other various forms of products under the inspiration of the present utility model. However, no matter what changes are made in the shape or structure, all those having the same or similar technical solutions as the present application fall within the protection scope of the present utility model.
