Technical Field

[0001] This utility model belongs to the field of water conservancy engineering technology, and specifically relates to a water conservancy pipeline interface sealing device. Background Technology

[0002] Water conservancy and hydropower projects are important infrastructure and basic industries in my country. Pipelines are indispensable in the construction of water conservancy and hydropower projects. In the construction of water conservancy and hydropower pipelines, it is necessary to connect two pipelines. The sealing of the pipeline connection directly determines the safety of water conservancy and hydropower projects.

[0003] However, in existing technologies, as pipelines are used for a long time, the connection between the two pipelines will loosen. When this loosening occurs, the sealing performance of the pipeline will decrease, thereby reducing the safety of the water conservancy project. Currently, most pipeline sealing and fastening devices are installed using flanges and bolts. During installation, workers need to turn the bolts many times, which is time-consuming and laborious, making it inconvenient for workers to disassemble and reassemble the sealing and fastening device and the pipeline. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a sealing device for water conservancy pipeline interfaces.

[0005] To achieve the above objectives, this utility model provides a water conservancy pipeline interface sealing device, which includes a first pipeline and a second pipeline. One end of the first pipeline is fixedly connected to a plug block, which is inserted into the inside of the second pipeline. Both the first and second pipelines have slots on their exteriors, and a sealing and fastening mechanism is provided on the exteriors of the first and second pipelines.

[0006] The sealing and fastening mechanism is used to fasten the No. 1 pipe and the No. 2 pipe.

[0007] In the above technical solution, the sealing and fastening mechanism further includes calipers, the inner sides of the two calipers are engaged in the inside of the caliper groove, one side of the caliper is rotatably connected to a threaded rod and fixedly connected to a sliding rod, and the other caliper is threadedly connected to the outside of the threaded rod and slidably connected to the outer wall of the sliding rod.

[0008] In the above technical solution, further, one end of each of the two calipers is slidably connected to an installation rod, the outer wall of the installation rod is threadedly connected to a threaded block, one side of the threaded block is in contact with one side of the caliper, and the outer wall of the installation rod is provided with a storage groove.

[0009] In the above technical solution, a support rod is rotatably connected inside the storage slot, and a second spring is rotatably connected to one side of the support rod. The end of the second spring away from the support rod is rotatably connected to the inside of the mounting rod.

[0010] In the above technical solution, a fixing rod is further slidably connected inside the mounting rod, and a No. 1 spring is fixedly connected to one end of the fixing rod inside the mounting rod, and one end of the No. 1 spring is fixedly connected inside the mounting rod.

[0011] In the above technical solution, a limiting block is further fixedly connected to the outside of the mounting rod, and the limiting block is located on one side of the support rod.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] In this invention, after the operator rotates the threaded rod, the distance between the two clamps can be brought closer, thereby applying a squeezing force between pipe No. 1 and pipe No. 2, making the connection between pipe No. 1 and pipe No. 2 more stable and thus enhancing its sealing performance. In addition, the operator can press the fixing rod to retract the support rod into the installation rod and then separate it from the clamps. Through this design, the pipe sealing performance can be enhanced, and the operator only needs to rotate the threaded block a few turns to disassemble and assemble the clamps and pipes. Compared with the traditional flange bolt installation, the convenience of disassembling and assembling the clamps and pipes is improved. Attached Figure Description

[0024] Example 1

[0025] like Figure 1 - Figure 6 The water conservancy pipeline interface sealing device shown includes a first pipeline 1 and a second pipeline 11. One end of the first pipeline 1 is fixedly connected to a plug block 12, which is inserted into the inside of the second pipeline 11. Both the first pipeline 1 and the second pipeline 11 are provided with a slot 13 on their exteriors. A sealing and fastening mechanism 2 is provided on the exteriors of the first pipeline 1 and the second pipeline 11. The sealing and fastening mechanism 2 is used to fasten the first pipeline 1 and the second pipeline 11.

[0026] In this embodiment, if the worker needs to install between pipe 1 and pipe 11, the fixed plug 12 on one side of pipe 1 can be inserted into the interior of pipe 11. Since the length of plug 11 is the same as the depth of the groove on one side of pipe 12, when plug 12 is fully inserted into the interior of pipe 11, one side of pipe 1 and one side of pipe 11 fit together, and the installation between pipe 1 and pipe 11 is completed.

[0027] Example 2

[0028] like Figure 1 - Figure 6 The water pipe interface sealing device shown includes a sealing and fastening mechanism 2 comprising clamps 21. The inner sides of two clamps 21 are engaged inside a clamping groove 13. One clamp 21 has a threaded rod 22 rotatably connected to one side and a sliding rod 23 fixedly connected to the other side. The other clamp 21 is threadedly connected to the outer side of the threaded rod 22 and slidably connected to the outer wall of the sliding rod 23. One end of each clamp 21 is slidably connected to an mounting rod 24. A threaded block 25 is threadedly connected to the outer wall of the mounting rod 24. One side of the threaded block 25 fits against one side of the clamp 21. The outer wall of the mounting rod 24... A storage slot 26 is provided, and a support rod 29 is rotatably connected inside the storage slot 26. A second spring 291 is rotatably connected to one side of the support rod 29. The end of the second spring 291 away from the support rod 29 is rotatably connected to the inside of the mounting rod 24. A fixing rod 27 is slidably connected inside the mounting rod 24. A first spring 28 is fixedly connected to one end of the fixing rod 27 inside the mounting rod 24. One end of the first spring 28 is fixedly connected to the inside of the mounting rod 24. A limit block 292 is fixedly connected to the outside of the mounting rod 24. The limit block 292 is located on one side of the support rod 29.

[0029] In this embodiment, after the installation of pipe 1 and pipe 11 is completed, if it is necessary to tighten the connection between pipe 1 and pipe 11 to enhance their sealing performance, the operator can rotate the clamp 21 and engage the inner side of the clamp 21 with the slot 13. Then, the installation rod 24 is inserted into one side of the clamp 21. During the insertion of the installation rod 24, one side of the clamp 21 will press against the outside of the support rod 29. After being pressed, the outside of the support rod 29 will rotate and move into the receiving slot 26, and the second spring 291 will elastically deform and contract. When all four support rods 29 have completely passed through one side of the clamp 21, the second spring 291, which is in an elastic deformation state, will rebound. This causes the support rod 29 to rotate and unfold again, thus limiting the clamp 21. After the support rod 29 has limited the clamp 21, the operator can rotate the threaded block 25 and make the threaded block 25 and one side of the clamp 21 fit together, so that the clamp 21 can squeeze the outer wall of pipe 1 and pipe 11. After the above steps are completed, the operator can simultaneously rotate the two threaded rods 22 to make one clamp 21 and the sliding rod 23 slide relative to each other, and bring the two clamps 21 closer together. During this process, a squeezing force can be applied between pipe 1 and pipe 11, thus completing the compression of pipe 1 and pipe 11. For securing the second pipe 11, if the worker needs to separate the installation rod 24 and the clamp 21, simply rotate the threaded block 25 slightly in the opposite direction to loosen the installation rod 24 and the clamp 21, then press the fixing rod 27. After being pressed, the fixing rod 27 will slide inside the installation rod 24, and one end of the fixing rod 27 will press against the end of the support rod 29, causing the support rod 29 to rotate in the direction of the receiving groove 26. After the support rod 29 rotates into the receiving groove 26, the worker can maintain the pressure on the fixing rod 27 to remove the installation rod 24 from inside the clamp 21.

[0030] Working principle: If workers need to install between pipe 1 and pipe 11, they can insert the fixed connector 12 on one side of pipe 1 into the interior of pipe 11. Since the length of connector 11 is the same as the depth of the groove on one side of pipe 12, when connector 12 is fully inserted into pipe 11, one side of pipe 1 and one side of pipe 11 will fit together, thus completing the installation between pipe 1 and pipe 11. After the installation between pipe 1 and pipe 11 is completed, if further installation is needed between pipe 1 and pipe 11... To enhance the seal, the clamps 21 are tightened together. The operator can rotate the clamp 21 and engage the inner side of the clamp 21 with the clamp slot 13. Then, the mounting rod 24 is inserted into one side of the clamp 21. During insertion, one side of the clamp 21 presses against the outside of the support rod 29. The support rod 29 rotates after being pressed and moves into the receiving slot 26, causing the second spring 291 to elastically deform and contract. When all four support rods 29 have completely passed through one side of the clamp 21, the second spring 291, which is in an elastic deformation state, will rebound. This causes the support rod 29 to rotate and unfold again, thus limiting the clamp 21. After the support rod 29 has limited the clamp 21, the operator can rotate the threaded block 25 and make the threaded block 25 and one side of the clamp 21 fit together, so that the clamp 21 can squeeze the outer wall of pipe 1 and pipe 11. After the above steps are completed, the operator can simultaneously rotate the two threaded rods 22 to make one clamp 21 and the sliding rod 23 slide relative to each other, and bring the two clamps 21 closer together. During this process, a squeezing force can be applied between pipe 1 and pipe 11, thus completing the compression of pipe 1 and pipe 11. For securing the second pipe 11, if the worker needs to separate the installation rod 24 and the clamp 21, simply rotate the threaded block 25 slightly in the opposite direction to loosen the installation rod 24 and the clamp 21, then press the fixing rod 27. After being pressed, the fixing rod 27 will slide inside the installation rod 24, and one end of the fixing rod 27 will press against the end of the support rod 29, causing the support rod 29 to rotate in the direction of the receiving groove 26. After the support rod 29 rotates into the receiving groove 26, the worker can maintain the pressure on the fixing rod 27 to remove the installation rod 24 from inside the clamp 21.
