Description

Technical Field

[0001] This utility model relates to the field of pipeline sealing technology, and in particular to a pipeline sealing structure for water conservancy projects. Background Technology

[0002] The sealing performance of water conservancy pipeline systems is directly related to water conveyance efficiency and project safety. In actual construction, pipelines often need to be extended or branched through connection structures. Traditionally, flange butt joints or socket joints are commonly used. Although these methods are widely used, they place higher demands on the sealing reliability, vibration resistance, and ease of installation, especially under complex geological conditions or frequent start-stop operations. Therefore, developing a new type of efficient and tightly sealed pipeline connection structure has significant engineering value and practical significance for ensuring the long-term stable operation of water conservancy systems, reducing water resource leakage, and lowering maintenance costs.

[0003] One common pipe connection method in existing technology relies on the fit between flanges and bolts. The technical principle is to fix two perforated flanges to the ends of the pipes to be connected, align them, and then use multiple bolts and nuts to tighten them circumferentially. The axial preload provided by the bolts is used to press the rubber gasket or metal washer between the two flanges to achieve a seal. Another common method is the socket connection, which involves inserting the spigot of one pipe into the socket of another pipe and filling the annular gap with sealing materials such as hemp or rubber rings. The elastic deformation of the material itself blocks the leakage path.

[0004] However, the aforementioned existing technology has a significant problem: its connection operation process is extremely cumbersome. For example, flange connection requires the alignment and sequential tightening of multiple bolts. This process is not only time-consuming and labor-intensive, but also requires high skill from the operators. It is difficult to ensure that the preload of each bolt is uniform, and improper tightening can easily lead to uneven stress on the gasket, reducing the sealing effect and ultimately causing leakage at the connection. This operational complexity seriously restricts construction efficiency, especially in situations where space is limited or rapid repairs are required. Therefore, a sealing structure for water conservancy pipelines is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a sealing structure for water conservancy engineering pipelines, which aims to improve the problems of poor sealing effect and cumbersome connection operation of traditional pipeline connections in the prior art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a sealing structure for a water conservancy engineering pipeline, comprising a pipe body one and a pipe body two, wherein the pipe body two is disposed on one side wall of the pipe body, a sealing component is disposed on the side wall of the pipe body two, and a connecting component is disposed on the outer wall of both the pipe body one and the pipe body two. The sealing assembly includes an insert block, a limiting block, a sealing ring, and a groove formed inside the tube body. One end of the insert block is fixedly connected to the two side walls of the tube body. The side wall of the limiting block is fixedly connected to the outer wall of the insert block. The outer wall of the insert block is rotatably connected inside the tube body. The outer wall of the sealing ring is fixedly connected inside the tube body. The sealing ring is in contact with the insert block. An arc-shaped block is slidably connected inside the tube body. A limiting plate is fixedly connected to the side wall of the arc-shaped block. The outer wall of the limiting plate is slidably connected inside the tube body. A guide post is fixedly connected to the side wall of the limiting plate. A spring is sleeved on the outer wall of the guide post.

[0007] As a further description of the above technical solution: One end of the spring is fixedly connected to the side wall of the limiting plate, and the other end of the spring is fixedly connected to the inside of the tube.

[0008] As a further description of the above technical solution: The connecting assembly includes an upper clamping block and a lower clamping block, the inner walls of which are respectively fitted onto the outer walls of the first tube and the second tube.

[0009] As a further description of the above technical solution: A second connecting block is fixedly connected to the outer wall of the upper clamping block, and a locking hole is provided inside the second connecting block.

[0010] As a further description of the above technical solution: A connecting block one is fixedly connected to the outer wall of the lower clamping block. A slot is provided inside the connecting block one, and the connecting block two is fitted into the slot.

[0011] As a further description of the above technical solution: A locking post is slidably connected inside the connecting block 1. The locking post engages with the locking hole. A sliding post is fixedly connected to the side wall of the locking post. The outer wall of the sliding post is slidably connected inside the connecting block 1.

[0012] As a further description of the above technical solution: A pull block is fixedly connected to the side wall of the sliding column, and a sliding block is fixedly connected to the outer wall of the sliding column. The outer wall of the sliding block is slidably connected inside the connecting block.

[0013] As a further description of the above technical solution: A second spring is provided on the side wall of the sliding block. One end of the second spring is fixedly connected to the side wall of the sliding block, and the other end of the second spring is fixedly connected to the inside of the first connecting block.

[0014] This utility model has the following beneficial effects: 1. In this utility model, by inserting the insert block into the first pipe body, and then rotating the second pipe body to make the limiting block rotate in the groove and squeeze the arc-shaped block, the arc-shaped block drives the limiting plate to squeeze the first spring. When the second pipe body rotates to the appropriate position, the first spring releases its elastic force to restrict the side wall of the limiting block. At the same time, the sealing ring and the insert block are in a tight fit, thereby realizing a quick and sealed connection between the first and second pipe bodies. This solves the problems of poor sealing effect and cumbersome connection operation in traditional pipe connections, and improves the sealing performance and convenience of pipe connections.

[0015] 2. In this utility model, by fitting the upper clamping block and the lower clamping block onto the outer walls of pipe body one and pipe body two, pulling the pull block causes it to drive the sliding column and the sliding block to squeeze the spring two. Then, closing the upper clamping block allows the connecting block two to be inserted into the slot. After releasing the pull block, the spring two releases its elastic force, causing the locking column to lock into the locking hole. This achieves quick and stable external fixation of the connection between pipe body one and pipe body two, solving the problems of complex installation and unstable fixation of traditional pipe external fixing devices, and improving the stability of pipe connection and the convenience of installation.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Reference Figures 1-4 The present invention provides an embodiment of a water conservancy engineering pipeline sealing structure, comprising a pipe body 1 and a pipe body 2, wherein the pipe body 1 and the pipe body 2 are tubular structures for extending the pipeline, the pipe body 2 is disposed on the side wall of the pipe body 1, and a sealing component is disposed on the side wall of the pipe body 2. The sealing component is used to enhance the sealing performance at the connection between the pipe body 1 and the pipe body 2 to prevent water leakage, and a connecting component is disposed on the outer wall of both the pipe body 1 and the pipe body 2. The connecting component is used to fix the connection part of the pipe body 1 and the pipe body 2 from the outside to enhance the stability of the connection. The sealing assembly includes an insert block 3, a limiting block 4, a sealing ring 6, and a groove 5 formed inside the tube body 1. One end of the insert block 3 is fixedly connected to the side wall of the tube body 2. The insert block 3 is used to initially connect the tube body 2 and the tube body 1, laying the foundation for subsequent sealing and fixation. The side wall of the limiting block 4 is fixedly connected to the outer wall of the insert block 3. The limiting block 4 is used to limit the rotation range of the insert block 3 within the tube body 1, preventing excessive rotation of the insert block 3 from affecting the sealing effect. The outer wall of the insert block 3 is rotatably connected inside the tube body 1. The insert block 3 rotates in coordination with the tube body 1 to rotate the limiting block 4 into the groove 5, achieving initial positioning of the insert block 3. The outer wall of the sealing ring 6 is fixedly connected inside the tube body 1. The sealing ring 6 contacts the insert block 3 and is used to fill the gap between the insert block 3 and the tube body 1 to enhance the sealing effect. An arc-shaped block 7 is slidably connected inside the tube body 1. The arc-shaped block 7 is used to interact with the limiting block 4. The two sides are in contact, forming a limit on the limiting block 4. The side wall of the arc-shaped block 7 is fixedly connected to the limiting plate 8. The outer wall of the limiting plate 8 is slidably connected inside the tube body 1. The limiting plate 8 is used to drive the arc-shaped block 7 to move synchronously, while limiting the sliding direction of the arc-shaped block 7. The side wall of the limiting plate 8 is fixedly connected to the guide post 9. The guide post 9 is used to provide guidance for the installation and extension of the spring 10, preventing the spring 10 from deviating. The outer wall of the guide post 9 is fitted with the spring 10. One end of the spring 10 is fixedly connected to the side wall of the limiting plate 8, and the other end of the spring 10 is fixedly connected to the inside of the tube body 1. The spring 10 cooperates with the limiting plate 8 and the arc-shaped block 7 to perform extension and retraction movements. When the limiting block 4 squeezes the arc-shaped block 7, the spring 10 is compressed and stores elastic potential energy. When the limiting block 4 rotates to the appropriate position, the spring 10 releases elastic potential energy to push the arc-shaped block 7 to limit the limiting block 4, thereby stabilizing the position of the limiting block 4.

[0020] Reference Figure 5 and Figure 6 The connecting assembly includes an upper clamping block 11 and a lower clamping block 12. The inner walls of the upper clamping block 11 and the lower clamping block 12 are respectively fitted onto the outer walls of pipe body 1 and pipe body 2. The upper clamping block 11 and the lower clamping block 12 are used to wrap and clamp the connecting parts of pipe body 1 and pipe body 2 from the outside of the pipe body, thereby enhancing the stability of the connection. A connecting block 2 14 is fixedly connected to the outer wall of the upper clamping block 11. A locking hole 15 is opened inside the connecting block 2 14. The connecting block 2 14 is used to cooperate with the connecting block 1 13 to realize the connection between the upper clamping block 11 and the lower clamping block 12. The locking hole 15 is used to cooperate with the locking post 17 to realize the connection between the connecting block 1 13 and the lower clamping block 12. The locking mechanism of connecting block 2 14 involves connecting block 1 13, which is fixedly connected to the outer wall of lower clamping block 12. Connecting block 1 13 has an internal slot 16, which engages with connecting block 2 14. Connecting block 1 13 connects to upper clamping block 11 and lower clamping block 12. Slot 16 provides insertion space for connecting block 2 14, achieving initial docking between connecting block 1 13 and connecting block 2 14. A locking post 17 is slidably connected inside connecting block 13, engaging with locking hole 15. The locking post 17 is inserted into locking hole 15 to fix connecting block 1 13 and connecting block 2 14 together. To achieve the locking effect of the upper clamping block 11 and the lower clamping block 12, a sliding post 18 is fixedly connected to the side wall of the locking post 17. The outer wall of the sliding post 18 is slidably connected inside the connecting block 13. The sliding post 18 is used to drive the locking post 17 to slide, facilitating the engagement and disengagement of the locking post 17 and the locking hole 15. A pull block 19 is fixedly connected to the side wall of the sliding post 18, providing a force point for the operator to pull the sliding post 18. A sliding block 20 is fixedly connected to the outer wall of the sliding post 18, slidably connected inside the connecting block 13. The sliding block 20 is used to cooperate with the spring 21 to drive... The sliding post 18 and the locking post 17 are reset, and the sliding range of the sliding post 18 is limited. A second spring 21 is provided on the side wall of the sliding block 20. One end of the second spring 21 is fixedly connected to the side wall of the sliding block 20, and the other end of the second spring 21 is fixedly connected to the inside of the connecting block 13. The second spring 21 works with the sliding block 20, the sliding post 18 and the locking post 17 to perform telescopic movement. When the pull block 19 is pulled, the second spring 21 is compressed. After the pull block 19 is released, the second spring 21 releases elastic potential energy to push the sliding block 20, the sliding post 18 and the locking post 17 to reset, so that the locking post 17 is inserted into the locking hole 15, achieving the effect of automatic locking.

[0021] Working principle: When internally connecting tube body 1 and tube body 2, insert block 3 of tube body 2 is inserted into tube body 1. Rotating tube body 2 causes the limiting block 4 on the outer wall of insert block 3 to rotate along the groove 5 of tube body 1. During rotation, the limiting block 4 presses the arc-shaped block 7 inside tube body 1. The arc-shaped block 7 drives the limiting plate 8 to slide along the inner wall of tube body 1. At the same time, the limiting plate 8 compresses the spring 10 on the guide post 9. The spring 10 stores elastic potential energy due to deformation. When tube body 2 rotates to the preset position, the spring 10 releases its elasticity. Potential energy pushes the limiting plate 8 to reset, and the arc-shaped block 7 resets accordingly to restrict the side of the limiting block 4, thereby achieving axial restriction of tube body 1 and tube body 2. At this time, the sealing ring 6 inside tube body 1 is tightly fitted with the outer wall of the insert block 3, filling the gap between the two to form a seal. When disassembling, it is only necessary to rotate tube body 2 to make the limiting block 4 squeeze the arc-shaped block 7 on the other side. After it is freed from the restriction between the two arc-shaped blocks 7, continue to rotate tube body 2 so that the limiting block 4 and the sliding groove opened in tube body 1 coincide, and tube body 1 and tube body 2 can be separated.

[0022] When connecting the outer walls of pipe body 1 and pipe body 2, the upper clamping block 11 and the lower clamping block 12 are placed at the connection point of the outer walls of pipe body 1 and pipe body 2. Pulling the pull block 19 moves the sliding column 18 and the sliding block 20. The sliding block 20 compresses the spring 21 inside the connecting block 13, causing the locking column 17 to retract into the connecting block 13. The upper clamping block 11 is closed, allowing the connecting block 24 to be inserted into the slot 16 of the connecting block 13. After releasing the pull block 19, the spring 21 pushes the sliding block 20 to reset. The sliding column 18 drives the locking column 17 to extend and engage with the locking hole 15 of the connecting block 24, thus securing the upper clamping block 11 and the lower clamping block 12, improving stability and ease of installation.
