Description

Technical Field

[0001] This utility model relates to a water conservancy pipeline, and more particularly to a water conservancy pipeline used in water conservancy projects, belonging to the field of water conservancy engineering technology. Background Technology

[0002] In water conservancy projects, traditional underground water pipes are usually buried underground. However, during actual construction, due to soil settlement or the influence of external construction activities, these pipes often change shape, thereby reducing their compressive strength. In this case, the stability of the pipes will be affected, which may lead to a series of problems, such as leakage or rupture.

[0003] Furthermore, if buried water pipelines are covered with too shallow soil, they will be more susceptible to the effects of external pressure and temperature changes. If the soil cover is too shallow, the pipeline will become unstable when it encounters thermal expansion and contraction or external pressure, and thus will not be able to effectively absorb the energy impact from the outside world, resulting in increased stress on the pipeline structure and ultimately affecting its service life.

[0004] To address the aforementioned technical problems, a water conservancy pipeline for water conservancy projects is proposed. Utility Model Content

[0005] In view of this, the present invention provides a water conservancy pipeline for water conservancy projects to solve or alleviate the technical problems existing in the prior art, and at least provides a beneficial alternative.

[0006] The technical solution of this utility model is as follows: a water conservancy pipeline for water conservancy projects, including a main structure and an internal support structure;

[0007] The main structure includes an outer tube and an inner tube, the inner tube being disposed inside the outer tube, and the outer side wall of the inner tube being integrally formed with a spiral groove.

[0008] The inner support mechanism includes a fixing ring and an inner support tube. The inner support tube is located between the outer tube and the inner tube and is sleeved on the outside of the inner tube. The outer side of the inner support tube has an integrally formed honeycomb groove. A rubber sleeve is fixedly connected inside the inner support tube. A spiral strip is integrally formed on the inner side of the rubber sleeve. The spiral strip engages with the spiral groove of the inner tube. Two fixing rings are fixedly connected to both ends of the inner support tube. The fixing rings are fixedly connected to both the outer tube and the inner tube.

[0009] More preferably, the outer tube is symmetrically fixedly connected to a support frame, and the support frame has equidistantly distributed hollow grooves inside.

[0010] More preferably, both ends of the outer tube are fixedly connected to flanges.

[0011] More preferably, a sealing ring is fixedly installed on one side of the flange.

[0012] More preferably, the inner wall of the inner tube is integrally formed with raised ribs, and the raised ribs are spirally arranged.

[0013] More preferably, the inner wall of the inner tube is coated with a hydrophobic coating.

[0014] The present invention has the following advantages due to the adoption of the above technical solution:

[0015] This invention features a double-layer pipe structure. An inner support pipe with honeycomb grooves is installed between the outer and inner pipes. Under stress, the hexagonal arrangement of the honeycomb structure evenly disperses external impact forces, and energy is absorbed through the elastic deformation of the unit walls. This maintains the pipe's lightweight design while enhancing its pressure resistance. A rubber sleeve is installed between the inner support pipe and the inner pipe, and the sleeve is attached to the inner pipe via a spiral strip. The sleeve can be deformed by the inner pipe, allowing for slight deformation under external pressure and temperature changes. The spiral grooves on the outer wall enhance the axial tensile strength of the inner pipe, evenly distributing external pressure across the entire pipe wall and preventing flattening or cracking caused by localized stress concentration.

In addition to the illustrative aspects, embodiments, and features described above, further aspects, embodiments, and features of the present invention will become readily apparent from the accompanying drawings and the following detailed description.

[0025] In the following description, only certain exemplary embodiments are briefly described. As those skilled in the art will recognize, the described embodiments can be modified in various ways without departing from the spirit or scope of this invention. Therefore, the drawings and description are considered exemplary in nature and not restrictive.

[0026] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0027] like Figure 1-6 As shown, this utility model embodiment provides a water conservancy pipeline for water conservancy projects, which consists of a main body 10 and an inner support mechanism 20.

[0028] The main structure 10 includes an outer tube 11 and an inner tube 12. The inner tube 12 is coaxially arranged with the outer tube 11 and is located inside the outer tube 11. The inner and outer layers are designed separately. The inner tube 12 is in direct contact with the fluid and is responsible for ensuring hygiene and corrosion resistance. The outer tube 11 provides mechanical support and pressure protection, making the pipeline more stable in complex environments. The inner support mechanism 20 is fixed between the outer tube 11 and the inner tube 12. The outer wall of the inner tube 12 is integrally formed with a spiral groove 18, which improves the axial tensile strength of the inner tube 12 and evenly distributes the external pressure to the entire inner tube 12 wall, avoiding flattening or cracking caused by local stress concentration.

[0029] In one embodiment, in order to reduce the natural sinking of the water pipe after it is buried, a support frame 15 is symmetrically fixed to the outside of the outer pipe 11, and the support frame 15 is provided with hollow grooves 16 evenly distributed inside to provide gripping points during transportation.

[0030] In one embodiment, to facilitate the connection between water pipes, flanges 13 are fixedly connected to both ends of the outer pipe 11, and a sealing ring 14 is fixedly installed on one side of the flange 13 to enhance the sealing of the connection.

[0031] In one embodiment, the inner wall of the inner tube 12 is integrally formed with spirally arranged protruding ribs 17, which increases fluid turbulence inside the tube, reduces laminar flow resistance, improves drainage efficiency, and reduces noise.

[0032] In one embodiment, the inner wall of the inner tube 12 is coated with a hydrophobic coating 19, which is a polyethylene coating, to enhance the corrosion resistance, water resistance and flexibility of the inner wall of the pipe.

[0033] The inner support mechanism 20 includes a fixing ring 21 and an inner support tube 22. The inner support tube 22 is located between the outer tube 11 and the inner tube 12, and the outer diameter of the inner support tube 22 is the same as the inner diameter of the outer tube 11. The inner diameter of the inner support tube 22 is slightly larger than the outer diameter of the inner tube 12. The inner support tube 22 is sleeved on the outside of the inner tube 12. The outer side of the inner support tube 22 is integrally formed with honeycomb grooves 24. When subjected to force, the hexagonal arrangement of the honeycomb grooves 24 can evenly disperse the external impact force and absorb energy through the elastic deformation of the unit wall, thereby enhancing the hydraulic system while maintaining the lightweight of the pipeline. The pipe has good pressure resistance. The inner support tube 22 is fixedly connected to a rubber sleeve 23. The inner side of the rubber sleeve 23 is integrally formed with a spiral strip 25. The spiral strip 25 engages with the spiral groove 18 of the inner tube 12. The rubber sleeve 23 can be deformed by the inner tube 12. The inner tube 12 is allowed to undergo slight deformation when affected by external pressure and temperature changes. Two fixing rings 21 are fixedly connected to both ends of the inner support tube 22. The fixing rings 21 are fixedly connected to both the outer tube 11 and the inner tube 12, thereby forming the outer tube 11, the inner tube 12 and the inner support tube 22 into one unit.

[0034] In one embodiment, the fixing ring 21 is removed, the inner support tube 22 and the rubber sleeve 23 are pre-placed on the outside of the inner tube 12, and the inner tube 12 and the outer tube 11 are sealed at both ends to form a double tube structure.

[0035] In operation, this utility model utilizes a support frame 15 to transport the water pipes, assemble them, and then bury them in the designated location. The support frame 15 increases the contact area between the water pipes and the soil, thereby reducing the natural settling of the water pipes after burial. The water pipes are connected by flanges 13 and bolts, and the sealing rings 14 fit together after connection to enhance the sealing performance at the joint. When water flows through, it flows along the spirally arranged protruding ribs 17 inside the inner pipe 12, increasing fluid turbulence inside the pipe and reducing laminar flow resistance. An inner support pipe exists between the outer pipe 11 and the inner pipe 12. 22 provides mechanical support and pressure protection. When under stress, the hexagonal structure of the honeycomb groove 24 can evenly disperse the external impact force and absorb energy through the elastic deformation of the unit wall. Thus, while maintaining the lightweight of the pipeline, it enhances the pressure resistance of the hydraulic pipeline. When the inner tube 12 is affected by external pressure and temperature changes, it undergoes slight deformation, squeezing the rubber sleeve 23 to prevent the inner tube 12 from rigidly breaking. The spiral groove 18 on the outer wall of the inner tube 12 improves the axial tensile strength and evenly disperses the external pressure to the entire pipe wall, avoiding flattening or cracking caused by local stress concentration.

[0036] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various variations or substitutions within the technical scope disclosed in this utility model, and these should all be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
