Description

Technical Field

[0001] This utility model relates to a wear-resistant water pipe for temporary water diversion. Background Technology

[0002] In long-distance water transfer projects, water pipes are required to transport water over long distances. Due to the long distances involved in laying the pipes, they need to be dragged and pulled during the installation process. The surface of the flexible hoses in traditional technology is easily worn down under long-distance dragging, and they will develop holes after prolonged use. In long-distance water transfer projects, the terrain is usually quite harsh, with a relatively large number of sharp objects on the ground, so the probability of damage is relatively high.

[0003] To address this, we designed a more wear-resistant temporary water pipe for temporary water supply. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a more wear-resistant temporary water pipe for water diversion.

[0005] To solve the above problems, the present invention adopts the following technical solution:

[0006] A wear-resistant water pipe for temporary water diversion includes multiple water pipe units. The appropriate number of water pipe units are selected and assembled according to the span of the water diversion. Each water pipe unit includes an inner layer and an explosion-proof mesh attached to the outside of the inner layer. A wear-resistant layer is injection molded on the outside of the explosion-proof mesh. A sealing connector is installed between adjacent water pipe units.

[0007] Preferably, the wear-resistant layer is injection molded with multiple wear-resistant rings on its outer surface, and when the two water pipe units are assembled, the wear-resistant rings cooperate with the sealing connector.

[0008] Preferably, an annular groove is formed between two adjacent wear-resistant rings, and a connecting groove is provided on the outer wall of the wear-resistant ring, the connecting groove connecting two adjacent annular grooves, and a reinforcing rope is wound in the annular groove, the reinforcing rope passing through the connecting groove.

[0009] Preferably, the sealing connector includes a spacer block, with two coaxial insertion ends on both ends of the spacer block, and a flow hole passing through the insertion ends. During installation, the spacer block is located between two adjacent water pipe units, the insertion ends are inserted into the inner layer, and a seal is formed between them and the inner wall of the inner layer. The spacer block is fitted with upper and lower clamping members, and screws are fitted between the clamping members and the spacer block. The inner side of the clamping members is provided with a groove, and the wear-resistant ring is inserted into the groove.

[0010] Preferably, the depth of the connecting groove is greater than the diameter of the reinforcing rope, and a gap is formed between the two clamps, which corresponds to the connecting groove. When the two clamps are tightened, the gap is smaller than the diameter of the reinforcing rope, and the reinforcing rope passes through the inside of the two clamps.

[0011] Preferably, the end of the insertion end away from the spacer block is machined to form a tapered guide surface, and the small end diameter of the guide surface is smaller than the inner diameter of the inner layer.

[0012] Preferably, annular grooves are machined at both ends of the spacer block, and a sealing ring is inserted into the groove, forming a seal between the sealing ring and the wear-resistant layer.

[0013] The beneficial effects of this utility model are:

[0014] In this technical solution, by thickening the wear-resistant layer and combining it with the wear-resistant blocks on the outside, the wear-resistant blocks bear the wear and tear during the dragging process, increasing the wear resistance during dragging and preventing the wear from going through.

[0015] After a certain amount of wear occurs, reinforcement can be provided by wrapping reinforcing ropes. The reinforcing ropes can firstly increase the water pipe's resistance to explosion, and secondly, after the wear-resistant rings wear out, the reinforcing ropes can bear the wear by contacting the ground.

[0016] This device uses sealed connectors, which can complete the connection of two water pipe units more quickly and with high connection efficiency. Attached Figure Description

[0025] In the description of this utility model, it should be understood that the terms "one end", "the other end", "outer side", "upper", "inner side", "horizontal", "coaxial", "center", "end", "length", "outer end", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings.

[0027] In this utility model, unless otherwise explicitly specified and limited, the terms "set," "socket," "connect," "through," and "plug-in" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0028] See Figures 1 to 4 The illustration shows a wear-resistant water pipe for temporary water diversion, comprising a water pipe unit 1, of which multiple water pipe units 1 are provided. The appropriate number of water pipe units 1 are selected for assembly according to the span of water diversion. In this embodiment, the length of a single water pipe unit 1 is 40 meters. The water pipe unit 1 includes an inner layer 11 and an explosion-proof mesh 12 attached to the outside of the inner layer 11. A wear-resistant layer 2 is injection molded on the outside of the explosion-proof mesh 12. A sealing connector 3 is installed between adjacent water pipe units 1.

[0029] The inner layer is made of TPE material, which is soft, stretchable, and does not harden.

[0030] Explosion-proof mesh gives water pipes stronger explosion-proof performance.

[0031] Explosion-proof mesh is made of polyester fiber (PET), which has high strength and fatigue resistance, and is often used in fire hoses and low-pressure hoses.

[0032] See Figures 1 to 4 As shown, the wear-resistant layer 2 has multiple wear-resistant rings 21 injection molded on its outer surface. When the two water pipe units are assembled, the wear-resistant rings cooperate with the sealing connector.

[0033] The second wear-resistant layer is made of rubber with a relatively high wear resistance coefficient, which does not affect the overall bending and storage of the water pipe.

[0034] The design of the wear-resistant ring 21 increases the wear time when dragging on the ground, and even if partial wear occurs, it will not wear down to the inner layer.

[0035] The wear-resistant layer 2 can be integrally injection molded with the wear-resistant ring 21, or it can be injection molded separately.

[0036] In the split injection molding process, the wear-resistant layer 2 can be extruded first, and then the wear-resistant ring 21 can be injection molded.

[0037] In one-piece injection molding, the wear-resistant layer 2 and the wear-resistant ring 21 are integrally injection molded using an independently designed mold.

[0038] Due to the limited length of the mold, there will be a certain degree of insufficient sealing between two adjacent wear-resistant layers 2, which requires secondary hot-melt processing to ensure sealing and integrity.

[0039] The thickness of the wear-resistant layer 2 is the same as or slightly greater than the thickness of the outer shell layer of a traditional water pipe.

[0040] See Figure 1 and Figure 2 As shown, an annular groove 22 is formed between two adjacent wear-resistant rings 21. A connecting groove 23 is provided on the outer wall of the wear-resistant ring 21. The connecting groove 23 connects two adjacent annular grooves 22. A reinforcing rope 24 is wound in the annular groove 22 and passes through the connecting groove 23.

[0041] The function of the reinforcing rope 24 is to reinforce the exterior of the wear-resistant layer 2 as a whole, especially during temporary high-pressure transportation, which can reduce the chance of pipe bursting.

[0042] Meanwhile, the reinforcement rope 24 is designed to withstand wear and tear on the wear-resistant ring 21 when dragging over long distances. The reinforcement rope 24 is detachable and replaceable, which can extend the service life of the water pipe by replacing the reinforcement rope 24 after the wear-resistant ring 21 wears out.

[0043] See Figure 3 and Figure 4 As shown, the sealing connector 3 includes a spacer block 31. Both ends of the spacer block 31 are coaxially provided with insertion ends 32. A flow hole 3333 passes through the insertion ends 32 at both ends. During installation, the spacer block 31 is located between two adjacent water pipe units 1. The insertion ends 32 are inserted into the inner layer 11 and form a seal with the inner wall of the inner layer 11. The spacer block 31 is fitted with two clamping parts 33, and screws 34 are fitted between the clamping parts 33 and the spacer block 31. The inner side of the clamping parts 33 is provided with a groove 331, and the wear-resistant ring 21 is inserted into the groove 331.

[0044] In the above technical solution, the wear-resistant ring 21 is inserted into the groove 34 by the assembly of the clamp 33, so that the water pipe units at both ends are limited by the clamp 33 to prevent disconnection during water transportation. Compared with the traditional form of pipe joint manufacturing, this sealing connector 3 can complete the docking of two water pipe units more quickly.

[0045] See Figure 1 , Figure 2 and Figure 5 As shown, the depth of the connecting groove 23 is greater than the diameter of the reinforcing rope 24, and a gap 332 is formed between the two clamps 33. This gap 332 corresponds to the connecting groove 23. When the two clamps are tightened, the gap is smaller than the diameter of the reinforcing rope, and the reinforcing rope passes through the inside of the two clamps.

[0046] In this technical solution, the reinforcing rope 24 can pass through the inside of the two clamps 33, thus avoiding the reinforcing rope 24 from being worn first during the traction and laying process.

[0047] See Figure 4 As shown, the end of the plug-in end 32 away from the spacer block 31 is machined to form a tapered guide surface 322, and the small end diameter of the guide surface 322 is smaller than the inner diameter of the inner layer 11.

[0048] This technical solution facilitates the insertion of the plug-in end 32 into the inner layer 11.

[0049] See Figure 4 As shown, annular first grooves are machined at both ends of the spacer block 31, and sealing rings 3111 are inserted into the first grooves, forming a seal between the sealing rings 3111 and the wear-resistant layer 2.

[0050] This technical solution can further enhance the sealing between the spacer block 31 and the water pipe unit 1.
