Description

Technical Field

[0001] This utility model relates to the field of water conservancy equipment technology, specifically to a water conservancy pipeline used in water conservancy projects. Background Technology

[0002] Water conservancy projects are projects built to control and regulate surface water and groundwater in nature to achieve the purpose of eliminating harm and promoting benefits. In water conservancy construction, it is often necessary to lay many pipelines. Since the length of a single pipeline is limited, it is necessary to splice the pipelines in order to lay long-distance pipelines. At this time, pipeline connection devices are used.

[0003] Chinese utility model CN216976211U proposes "a water conservancy pipeline for water conservancy projects". This device achieves automatic cleaning of the pipeline interior by setting up an impeller, scraper and filter screen driven by water flow. At the same time, it uses a telescopic baffle driven by centrifugal force to regulate the water flow speed, effectively preventing silt from eroding the pipe wall. However, this device mainly focuses on the fluid control and self-cleaning function inside the pipeline, and does not address or solve the technical problem of how to efficiently and reliably connect the pipeline sections. Its connection method may still use traditional welding methods. Therefore, in the on-site splicing and installation of the pipeline, there are still inherent defects such as inconvenient operation, difficulty in ensuring sealing, and long construction period. Utility Model Content

[0005] To achieve the above-mentioned technical objectives, the present invention adopts the following technical solution:

[0006] In a first aspect, this utility model provides a water conservancy pipeline for water conservancy projects, comprising:

[0007] The water conservancy pipe body includes a first pipe body and a second pipe body.

[0009] In some embodiments, a positioning ring is installed on the first tube and the second tube, near the positioning groove. The positioning ring has a plurality of screw holes circumferentially open, and the screw holes are connected to the upper connecting block and the lower connecting block by means of connectors.

[0010] In some embodiments, the lower end of the first extension block is provided with a protrusion, the side of the second extension block facing the protrusion is provided with a through groove, the protrusion extends into the through groove, and the lower end of the protrusion is connected to the flipping member through a connector.

[0011] In some embodiments, the flipping component includes a shaft and a rotating plate. The shaft is fixed to one end of the first extension block away from the upper connecting block. The rotating plate is rotatably connected to the shaft. The rotating plate is an L-shaped plate, and the lower end of the rotating plate is connected to the protrusion block through a connector.

[0025] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0026] Please see Figure 1 , Figure 1 This is a schematic diagram of the structure of a water conservancy pipeline for water conservancy projects according to one embodiment of the present invention. The water conservancy pipeline for water conservancy projects includes:

[0027] The water conservancy pipe body 1 includes a first pipe body 11 and a second pipe body 12. An insertion block 111 and an insertion groove 121 are respectively provided on the adjacent side of the first pipe body 11 and the second pipe body 12. The insertion block 111 is used to extend into the insertion groove 121. A positioning groove 13 is provided on the outer wall of the first pipe body 11 and the second pipe body 12.

[0028] The connecting mechanism 2 includes an upper connecting block 21 and a lower connecting block 22. The upper connecting block 21 and the lower connecting block 22 are disposed at the connection between the first pipe body 11 and the second pipe body 12 and are used to seal it. The upper connecting block 21 and the lower connecting block 22 are provided with a positioning block 23 that cooperates with the positioning groove 13. The upper connecting block 21 and the lower connecting block 22 are respectively provided with a first extension block 211 and a second extension block 221 on both sides. The first extension block 211 is provided with a flipping member 24. The lower end of the flipping member 24 is disposed at the lower end of the second extension block 221 and is connected by a connecting member 25.

[0029] In this embodiment, by setting insertion blocks 111 and insertion slots 121 on the first pipe body 11 and the second pipe body 12, rapid guidance and precise alignment between the two pipe bodies are achieved, significantly improving splicing efficiency. At the same time, positioning slots 13 are set on the outer wall of the pipe body, and upper and lower connecting blocks 22 and their positioning blocks 23 are embedded in them, which not only provides a reliable installation benchmark for the connecting blocks, but also forms a circumferential sealing support structure around the pipe body, effectively ensuring the sealing performance of the connection. In addition, by setting first and second extension blocks 221 on both sides of the connecting blocks and connecting them with flipping parts 24, the operator can easily pull the upper and lower connecting blocks 22 tight and fit them against the outer wall of the pipe body by flipping them, and then fix them with connecting parts 25 to complete the locking of the entire connection mechanism 2. The whole process is simple to operate, saves time and effort, and greatly improves the convenience and reliability of on-site installation of water conservancy pipelines.

[0030] In one embodiment, please refer to Figure 3 - Figure 8 To improve the tightness of the connection between the first tube 11 and the second tube 12, a positioning ring 14 is installed on the first tube 11 and the second tube 12, near the positioning groove 13. The positioning ring 14 has multiple screw holes 141 circumferentially open. The screw holes 141 are connected to the upper connecting block 21 and the lower connecting block 22 via connectors 25. The lower end of the first extension block 211 is provided with a protrusion 212. The side of the second extension block 221 facing the protrusion 212 has a through groove 222. The protrusion 212 extends into the through groove 222, and the lower end of the protrusion 212 is connected to a flipping member 24 via connectors 25. The flipping member 24 includes a shaft 241 and a rotating plate 242. The first extension block 21... A shaft 241 is fixed at one end away from the upper connecting block 21. A rotating plate 242 is rotatably connected to the shaft 241. The rotating plate 242 is an L-shaped plate, and the lower end of the rotating plate 242 is connected to the protrusion block 212 through a connector 25. The flipping component 24 also includes a bending block 243. The bending block 243 is fixed on the side of the rotating plate 242 facing away from the shaft 241. The rotation angle of the rotating plate 242 is a, and 0° < a ≤ 90°. The connector 25 includes a first connecting bolt 251 and a second connecting bolt 252. The first connecting bolt 251 is used to connect the positioning ring 14 and the upper connecting block 21 or the lower connecting block 22. The second connecting bolt 252 is used to connect the rotating plate 242 and the protrusion block 212.

[0031] In this embodiment, by adding a positioning ring 14 near the positioning groove 13 and fixing the upper and lower connecting blocks 22 to the positioning ring 14 using the first connecting bolt 251, a crucial rigid reinforcement layer is added to the entire connection structure. The positioning ring 14, as a ring-shaped reinforcing rib, is fitted onto the pipe body, greatly improving the circumferential stiffness and deformation resistance of this weak link, effectively preventing the pipe body from becoming elliptical due to internal water pressure or external soil pressure. This device directly fixes the connecting blocks to the positioning ring 14 using the first connecting bolt 251, so that the locking force is distributed to the more robust structure of the positioning ring 14, significantly reducing the... The stress load on the flipping component 24 and the extension block is reduced, avoiding fatigue or deformation caused by local stress concentration. The bolted connection between the positioning ring 14 and the connecting block forms a strong axial and circumferential constraint, greatly enhancing the connection's ability to resist axial tensile force and circumferential torsional force of the pipeline, ensuring long-term stability under complex working conditions. By setting a protrusion 212 at the lower end of the first extension block 211, opening a matching through groove 222 on the second extension block 221, and using the shaft 241 to connect the rotating plate 242, precise linear guidance is provided for the movement of the flipping component 24, ensuring smooth flipping action. Smooth operation avoids difficulties caused by shaking or jamming. The shaft 241 serves as the rotation center of the rotating plate 242, ensuring the reliability of the flipping process. An L-shaped plate is used as the rotating plate 242, with a lever block 243 added to its back. The L-shaped structure naturally provides a lever arm. The force applied by the operator to the lever block 243 is transmitted to the rotation center, i.e., the shaft 241, through a longer lever arm. This allows for the generation of a large locking torque with a small input force. The lever block 243 provides a clear point of force application and a gripping surface, making operation easy even when wearing gloves. The rotation trajectory of the L-shaped plate is clear, allowing the operator to intuitively judge its movement. The locked state of the connection limits the rotation angle of the rotating plate 242 to a range greater than 0° and not exceeding 90°. The greater than 0° ensures that the rotating plate 242 can be completely released from the locked state for easy disassembly. The upper limit of 90° is sufficient to allow the L-shaped plate to rotate from the horizontal, unlocked state to the vertical fully locked state, achieving the maximum locking stroke and torque. The compact rotation range within 90° avoids interference with other structures due to excessive rotation in narrow construction spaces, improving on-site applicability. The limited angle prevents the rotating plate 242 from rotating excessively, causing the connector 25 to bear unnecessary shear force or structural deformation.

[0032] To better understand this utility model, the following is combined with... Figures 1 to 8The technical solution of this utility model is described in detail as follows: The connection ports of the first tube 11 and the second tube 12 to be connected are cleaned to ensure there are no foreign objects. The operator roughly aligns the axes of the first tube 11 (with the insertion block 111) and the second tube 12 (with the insertion groove 121), and pushes the first tube 11 so that the insertion block 111 at its end is aligned and smoothly inserted into the insertion groove 121 at the end of the second tube 12. During the insertion process, the cooperation between the insertion block 111 and the insertion groove 121 provides precise guidance, automatically correcting the relative positions of the two tubes and ensuring coaxial alignment. When the insertion block 111 is fully inserted into the insertion groove 121 and the end faces of the two tubes are tightly fitted, the first stage is completed, and the two tubes have achieved axial positioning and preliminary diameter alignment. To provide a stable foundation for subsequent sealing and locking, the upper connecting block 21 and the lower connecting block 22 are placed above and below the connection point of the two pipe bodies, respectively. Their positions are adjusted so that the positioning block 23 on the connecting block is accurately embedded in the positioning groove 13 opened on the outer wall of the first pipe body 11 and the second pipe body 12. This step ensures the circumferential positioning and installation reference of the connecting block. The protrusion 212 at the lower end of the first extension block 211 is inserted into the through groove 222 on the second extension block 221, and the rotating plate 242 is flipped so that the end of its L-shaped rotating plate 242 is located at the lower end of the protrusion 212. The second connecting bolt 252 is passed through the hole at the lower end of the rotating plate 242 and screwed into the corresponding threaded hole on the protrusion 212, firmly fixing the rotating plate 242 in place. On the protrusion 212, this step completes the final locking of the flip-locking mechanism, preventing it from accidentally loosening during operation. The first connecting bolt 251 is then passed through the screw hole 141 of the positioning ring 14 and the connecting block in sequence, tightening them. This step further fixes the upper and lower connecting blocks 22 to the positioning ring 14, adding a crucial rigid reinforcement layer to the entire connection structure, significantly improving the overall strength, deformation resistance, and long-term stability of the connection. It should be noted that a first annular sealing gasket is provided between the end faces of the first tube 11 and the second tube 12. When the insertion blocks 111 of the two tubes are fully inserted and fitted into the insertion grooves 121, an annular contact surface is formed between the two end faces. The first annular sealing gasket is pre-placed on this contact surface. When the upper and lower connecting blocks 22 are tightened and pressed against the outer wall of the pipe by the flipping mechanism, a huge locking force is transmitted through the connecting blocks, uniformly compressing the end face sealing gasket. The compressed gasket fills the microscopic unevenness between the two metal end faces, forming a primary barrier to prevent the medium from leaking out of the pipe. A second sealing annular gasket is provided between the inner surfaces of the upper connecting blocks 21 and lower connecting blocks 22 and the outer walls of the first pipe body 11 and second pipe body 12, especially around the mating area of ​​the positioning block 23 and the positioning groove 13. When the connecting block is embedded into the positioning groove 13 through the positioning block 23 and locked, the inner surface of the connecting block will be tightly attached to the outer wall of the pipe body. Placing the second annular sealing gasket between these mating surfaces can form a second seal.The main function of this seal is to prevent external contaminants such as dust, mud, and moisture from entering through the gaps between the connecting block and the pipe body, thus protecting the components and extending their service life.

[0033] The specific embodiments of this utility model described above do not constitute a limitation on the scope of protection of this utility model. Any other corresponding changes and modifications made based on the technical concept of this utility model should be included within the scope of protection of the claims of this utility model.
