Description

Technical Field

[0001] This utility model relates to the field of water conservancy pipeline technology, and in particular to a spiral pipe for drainage in water conservancy construction. Background Technology

[0002] Hydraulic engineering refers to various engineering activities carried out in and around rivers, lakes and other water bodies. The aim is to achieve effective management and utilization of water resources through the construction, repair and maintenance of hydraulic structures. These projects are of great significance for flood control and disaster reduction, irrigation water supply, power generation water supply and navigation.

[0003] The existing hydraulic drainage spiral pipes have the following shortcomings:

[0004] Existing spiral pipes are limited by their own structure. Although the material has a certain strength, the toughness they can provide is limited. The pipes are mostly buried in the soil. Affected by various external factors, the soil covering may be lost. In this state, if a part of the pipe is severely impacted, deformation will occur. Since the pipe cannot repair itself, the channel area is compressed, which not only affects the drainage efficiency but also increases the probability of blockage. Utility Model Content

[0005] This utility model proposes a spiral pipe for drainage in water conservancy construction. Through the coordinated operation of multiple components, air pressure and mechanical counter-propulsion are used to continuously weaken the impact force and apply the opposite force to the deformed part of the pipe, so as to slowly promote the restoration of the deformed area, thereby solving the problem of purification in the background technology mentioned above.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a hydraulic construction drainage spiral pipe, comprising an outer spiral pipe body, wherein an inner spacer is provided inside the outer spiral pipe body, and a set of sealing sleeves is fixedly installed on the outer wall of the inner spacer. Each sealing sleeve has a track groove inside, and a U-shaped lifting frame is fixedly installed at the bottom of the inner wall of each track groove. A set of hollow sleeves is fixedly installed inside each U-shaped lifting frame, and a metal slide rod is movably inserted inside each hollow sleeve. A square piston is fixedly sleeved between the outer walls of each set of metal slide rods. Each square piston is movably placed inside a corresponding sealing sleeve. An extension base is fixedly installed on the top of each square piston, and an arc-shaped alloy push plate is fixedly installed on the outer wall of each extension base.

[0007] Preferably, the outer wall of each of the arc-shaped alloy thrust plates is in contact with the inner wall of the outer spiral tube body, and a set of first air inlets is provided on both the front and rear sides of each of the sealing shells.

[0008] Preferably, each of the U-shaped lifting frames has a set of first circular holes at its top and each of the square pistons has a set of second circular holes at its bottom, with the number of first circular holes in each set being equal to the number of second circular holes in each set.

[0009] Preferably, an active spring is fixedly installed between each of the first and second circular holes, and each active spring is movably sleeved on the outer wall of a corresponding metal slide rod, and the inner wall of the inner tube of the spacer is provided with an inner spiral.

[0010] Preferably, annular protective plates are fixedly installed at both ends of the outer wall of the outer spiral tube body, and the outer walls of the inner tube are respectively connected to a corresponding annular protective plate. Each annular protective plate has a set of second air inlets inside, and an extension connector is fixedly installed on the inner surface of one annular protective plate.

[0011] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0012] 1. In this utility model, compressible air can be continuously supplied to the cavity through the various sets of air inlet holes. During the use of the pipeline, if the surface soil is lost, part of the pipe body will be exposed. When a foreign object impacts part of the pipe body, it will cause some materials to deform and continuously press down on the internal structure of the pipe. Subsequently, through the cooperation of multiple components, air pressure and mechanical reverse thrust are used to continuously weaken the impact force and apply the opposite external force to the deformed part of the pipe, slowly promoting the reset of the deformed area. This method mainly uses the external force to spontaneously realize the operation of the mechanical components, and with the cooperation of air compression reverse thrust, it realizes the weakening of the external force and the reset of the auxiliary materials, effectively preventing the compression of the internal channel, ensuring that the pipeline can always be in a relatively efficient water guiding state, and reducing the probability of internal channel blockage.

[0013] 2. In this utility model, the pipe body adopts a modular assembly mode, which ensures that the inner and outer pipes can work together or be distinguished independently. The method of docking and assembling each pipe separately greatly reduces the installation difficulty of multiple pipes of the same type. At the same time, this structure facilitates the disassembly and maintenance of the pipes. Attached Figure Description

[0020] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0021] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0022] Example 1, as shown in the attached document Figure 1 - Appendix Figure 5As shown, this utility model provides a technical solution: a hydraulic construction drainage spiral pipe, including an outer spiral pipe body 1, an inner spacer pipe 2 inside the outer spiral pipe body 1, a set of sealing sleeves 3 fixedly installed on the outer wall of the inner spacer pipe 2, a track groove is opened inside each sealing sleeve 3, and a U-shaped lifting frame 4 is fixedly installed at the bottom of the inner wall of each track groove, a set of hollow sleeves 5 is fixedly installed inside each U-shaped lifting frame 4, a metal slide rod 6 is movably inserted inside each hollow sleeve 5, and a square piston 7 is fixedly sleeved between the outer walls of each set of metal slide rods 6, each square piston 7 is movably placed inside a corresponding sealing sleeve 3, and an extension base is fixedly installed on the top of each square piston 7. 8. Each extended base 8 has an arc-shaped alloy thrust plate 9 fixedly installed on its outer wall. The outer wall of each arc-shaped alloy thrust plate 9 is in contact with the inner wall of the outer spiral tube body 1. Each sealing shell 3 has a set of first air inlets 13 on its two rear sides. Each U-shaped lifting frame 4 has a set of first round holes 10 on its top. Each square piston 7 has a set of second round holes 11 on its bottom. The number of first round holes 10 and the number of second round holes 11 in each set are equal. Each first round hole 10 and the second round hole 11 are fixedly installed between them. Each active spring 12 is movably sleeved on the outer wall of a corresponding metal slide rod 6. Each annular guard plate 15 has a set of second air inlets 16 inside its interior.

[0023] The overall effect achieved by Embodiment 1 is as follows: By pre-setting the above-mentioned components, since the pipeline needs to be laid in the soil, but it is in a shallow area, it is not possible to completely isolate the main air. Under this effect, the various sets of air inlets can continuously replenish the cavity with compressible air. During the use of the pipeline, if the surface soil is lost, part of the pipe will be exposed. When a foreign object impacts part of the pipe, it will cause some materials to deform and continuously press down on the internal structure of the pipe. Subsequently, through the collaboration of multiple components, air pressure and mechanical reverse thrust are used to continuously weaken the impact force and apply the opposite external force to the deformed part of the pipeline, slowly promoting the reset of the deformed area. This method mainly uses the external force to spontaneously realize the operation of the mechanical components, and with the cooperation of air compression reverse thrust, it realizes the weakening of the external force and the reset of the auxiliary materials, effectively preventing the compression of the internal channel, ensuring that the pipeline can always be in a relatively efficient water guiding state, and reducing the probability of internal channel blockage.

[0024] Example 2, as Figure 1-3 As shown, the inner wall of the inner tube 2 is provided with an inner spiral body 14, and both ends of the outer wall of the outer spiral tube body 1 are fixedly installed with annular protective plates 15. The two ends of the outer wall of the inner tube 2 are respectively connected to a corresponding annular protective plate 15, and an extension connector 17 is fixedly installed on the inner wall of an annular protective plate 15.

[0025] The overall effect of Embodiment 2 is as follows: by pre-setting the above components, the pipe body adopts a modular assembly mode, which ensures that the inner and outer pipes can work together or be distinguished independently. By adopting the docking and assembly method, the installation difficulty of multiple pipes of the same type is greatly reduced. At the same time, this architecture facilitates the disassembly and maintenance of the pipes.

[0026] The working principle of the entire pipeline is as follows: Based on the required quantity, pipe bodies of the same specifications are laid sequentially in the installation area. One end with the extension connector 17 is precisely positioned and deeply inserted into the end of another pipe. After sequential splicing, a complete water-conducting channel is formed. Subsequently, soil is filled to prevent the outer wall of the outer spiral pipe body 1 from being exposed. When the pipeline guides water, the air contained within the soil layer will first flow into the interior of the outer spiral pipe body 1 at the second air inlet 16 and the first air inlet 13, and then fill into each sealing sleeve 3. With the increase in usage time and the influence of external natural conditions, the soil covering the outer spiral pipe body 1 will experience varying degrees of loss, resulting in the exposure of part of the outer wall of the outer spiral pipe body 1. During this process, when a part of the outer wall is impacted by a foreign object, if the impact force exceeds the material's load-bearing capacity... As the deformation progresses, one or more arc-shaped alloy thrust plates 9 will press down on the inner wall of this area. Utilizing the movable connection between the sealing sleeve 3 and the square piston 7, the square piston 7 tends to press inward. When it moves to the end of the first air inlet 13, it prevents air from entering and continuously compresses the remaining trapped air inside the sealing sleeve 3. At the same time, utilizing the movable connection between the hollow sleeve 5 and the metal slide rod 6, the active spring 12 between the U-shaped lifting frame 4 and the square piston 7 is in a compressed state. As the pressure gradually disappears, the reaction force generated by the air pressure thrust and the active spring 12 will act simultaneously on the bottom of the square piston 7, pushing the arc-shaped alloy thrust plate 9 to apply a reverse external force to the interior of the deformed outer spiral tube body 1. The force can remain constant for a long time, slowly assisting the recovery of the deformed material.

[0027] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the present utility model.
