Abstract
Description
Technical Field
[0001] This utility model relates to the field of pipeline connection technology, specifically a connection structure for a temporary stable pipeline in an emergency drainage pumping station. Background Technology
[0002] Emergency drainage pumping stations are devices capable of rapid deployment and providing high-flow-rate drainage in emergency situations. Their primary function is to remove large amounts of accumulated water in a short time, ensuring the normal operation of the urban drainage system and reducing the impact of flooding on urban functions.
[0003] Currently, most existing emergency drainage pumping stations typically face complex operating conditions, such as strong vibrations caused by water flow impacts and pressure fluctuations due to rapid changes in water level. The bolts used for connecting pipes are prone to gradually loosening under these external forces, thereby damaging the sealing of the pipe connections. Once the sealing is compromised, leaks may occur, which not only reduces the drainage efficiency of the pumping station but may also cause the surrounding area to be flooded, affecting the normal progress of emergency rescue work and even threatening the safety of nearby infrastructure and personnel. In view of this, we propose a connection structure for temporary stable pipes in emergency drainage pumping stations. Utility Model Content
[0004] The main objective of this invention is to provide a connection structure for a temporary stable pipeline in an emergency drainage pumping station, which can solve the problems mentioned in the background art.
[0005] To achieve the above objectives, the present invention proposes the following technical solution:
[0006] A connection structure for a temporary stable pipeline in an emergency drainage pumping station includes a first pipeline, a flange first fixedly connected to the first pipeline, the flange first having a groove, and a second pipeline at one end of the first pipeline, the second pipeline being fixedly connected to a flange second. The first pipeline and the second pipeline are fixed together by a connecting assembly, the connecting assembly including:
[0007] Nut, which is welded to the outer wall of flange two;
[0008] A bolt, wherein a moving block is slidably connected to the inner wall of the bolt, and a rod is fixedly connected to the outer wall of the moving block. The rod passes through the bolt and is slidably connected to the bolt, and a toothed sleeve is fixedly connected to the end of the rod.
[0009] The second toothed sleeve is slidably connected to the groove, and the outer wall of the second toothed sleeve is fixedly connected to the second spring. The end of the second spring away from the second toothed sleeve is fixedly connected to the inner wall of the groove.
[0010] Preferably, one end of a spring is fixedly connected to the outer wall of the moving block, and the other end of the spring is fixedly connected to the inner wall of the bolt.
[0011] Preferably, the moving block is rotatably connected to a rotating rod, one end of which is fixedly connected to the outer wall of the rotating rod, and the other end of which is fixedly connected to the inner wall of the moving block.
[0012] Preferably, a sleeve is fixedly connected to the inner wall of the bolt, and the sleeve has an L-shaped groove.
[0013] Preferably, the L-shaped groove is slidably connected to a fixed rod, and the fixed rod is fixedly connected to the outer wall of the rotating rod.
[0014] Preferably, the rotating rod passes through the bolt and is sleeved with the bolt, and a hexagonal groove is provided at the top of the rotating rod.
[0015] This utility model provides a connection structure for a temporary stable pipeline in an emergency drainage pumping station. It has the following beneficial effects:
[0016] (1) The connection structure of the temporary stable pipeline of the emergency rescue pumping station, the design of the toothed sleeve one, toothed sleeve two, spring one, spring two and related structures in the connecting components, can effectively limit the bolt after tightening through the meshing between the toothed sleeves, which can prevent the bolt from loosening after long-term use due to external factors such as vibration and temperature changes. This ensures the stability and sealing of the connection between pipeline one and pipeline two, reduces the leakage problems that may occur due to poor sealing, effectively ensures the normal operation of the pipeline system, and reduces maintenance costs and safety risks.
[0017] (2) The connection structure of the temporary stable pipeline of the emergency rescue pumping station, through the structural design of rotating rod, hexagonal groove, L-shaped groove, fixed rod and arc spring, makes it easy to disassemble the pipeline connection by simply operating the rotating rod with a hexagonal wrench and releasing the limit of the toothed sleeve. During installation, the bolt tightening and toothed sleeve limit can be completed smoothly by following the corresponding steps, which improves the convenience of pipeline installation and disassembly, saves time and labor costs, and can significantly improve work efficiency and reduce the impact on production or operation, especially in scenarios where frequent pipeline maintenance, repair or replacement is required.

[0027] The realization of the purpose, functional features and advantages of this utility model will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation
[0028] 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.
[0029] Please see Figures 1-7 This utility model proposes a connection structure for a temporary stable pipeline of an emergency drainage pumping station, including a pipeline 1, a flange 2 fixedly connected to the pipeline 1, a groove 21 on the flange 2, a pipeline 3 at the end of the pipeline 1, a flange 4 fixedly connected to the pipeline 3, and the pipeline 1 and the pipeline 2 are fixed together by a connecting component.
[0030] In an embodiment of this utility model, in order to prevent the bolt 52 from loosening, the connecting assembly specifically includes a nut 51, which is welded to the outer wall of the flange 4. A moving block 521 is slidably connected to the inner wall of the bolt 52. A rod 522 is fixedly connected to the outer wall of the moving block 521. The rod 522 passes through the bolt 52 and is slidably connected to the bolt 52. A toothed sleeve 523 is fixedly connected to the end of the rod 522. The toothed sleeve 53 is slidably connected to the groove 21. A spring 531 is fixedly connected to the outer wall of the toothed sleeve 53. The end of the spring 531 away from the toothed sleeve 53 is fixedly connected to the inner wall of the groove 21.
[0031] Furthermore, one end of a spring 524 is fixedly connected to the outer wall of the moving block 521, and the other end of the spring 524 is fixedly connected to the inner wall of the bolt 52. The moving block 521 is rotatably connected to a rotating rod 526. One end of an arc-shaped spring 527 is fixedly connected to the outer wall of the rotating rod 526, and the other end of the arc-shaped spring 527 is fixedly connected to the inner wall of the moving block 521. A sleeve 520 is fixedly connected to the inner wall of the bolt 52. The sleeve 520 has an L-shaped groove 528. A fixed rod 525 is slidably connected to the L-shaped groove 528. The fixed rod 525 is fixedly connected to the outer wall of the rotating rod 526. The rotating rod 526 passes through the bolt 52 and is sleeved with the bolt 52. A hexagonal groove is opened at the top of the rotating rod 526.
[0032] In this utility model, during use, first align pipe 1 and pipe 2 3, then insert bolt 52 through flange 1 2 and flange 2 4 and rotate bolt 52 to make bolt 52 and nut 51 threadedly connected. Figure 5 As shown, the L-shaped groove 528 is composed of a horizontal groove and a straight groove, and the fixed rod 525, which is fixedly connected to the rotating rod 526, is located at the end of the straight groove. At this time, the toothed sleeve 1 523 is in a limited position, and the spring 1 524 is in an elastic tension state. When the bolt 52 rotates a certain distance, the inclined surface of the toothed sleeve 1 523 will continuously squeeze the toothed sleeve 2 53. At the same time, the toothed sleeve 2 53 will continuously mesh with the toothed sleeve 1 523 under the elastic force of the spring 2 531. When the bolt 52 is tightened, the toothed sleeve 1 523 and the toothed sleeve 2 53 are in a meshing state. Through the design of the toothed sleeve 1 523 and the toothed sleeve 2 53, the bolt 52 can be limited to prevent the bolt 52 from loosening due to external factors over a long period of time, thereby ensuring the sealing between pipe 1 and pipe 2 3.
[0033] When disassembly is required, first insert a hex wrench into the hexagonal slot, then rotate the rotating rod 526 90 degrees, causing it to move to the bottom of the vertical slot. Simultaneously, the arc spring 527 undergoes elastic deformation. When the rotating rod 526 reaches the bottom of the vertical slot, the vertical limit of the moving block 521 is released. At this point, under the elastic force of spring 524, the moving block 521 will drive the toothed sleeve 523 upwards, causing it to disengage from the toothed sleeve 523, thereby releasing the bolt 52. The gear sleeve 523 can be limited by turning the bolt 52 again. When the gear sleeve 523 needs to be limited, simply press the rotating rod 526 with a hex wrench to move the fixed rod 525 to the bottom of the channel. Then, rotate the rotating rod 526 ninety degrees to move the rotating rod 526 to the end of the straight channel, thereby limiting the gear sleeve 523. It should be noted that the design of the arc spring 527 can limit the fixed rod 525 and prevent the fixed rod 525 from sliding in the straight channel.
[0034] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
