Description

Technical Field

[0001] The utility model relates to the technical field of water conservancy projects, and more particularly to a leak-stopping device for water conservancy pipelines. Background Art

[0002] With the continuous development of water conservancy engineering technology, the complexity and importance of pipeline systems have become increasingly prominent. Rapid response and efficient handling of pipeline leaks have become the key to ensuring the safe and stable operation of water conservancy projects. Therefore, the research and development and application of leak-proof devices for water conservancy pipelines are particularly important. Leak-proof devices for water conservancy pipelines are a series of professional equipment and technical means designed to address possible leakage problems in water conservancy pipeline systems. The main purpose of these devices is to quickly and effectively seal leaks in the pipeline to prevent the waste of water resources and possible safety accidents. It mainly consists of two parts, sealing strips and fasteners, and is fastened with bolts and nuts.

[0003] In the prior art, for example, a patent with application number CN202021287192.6 discloses: a leak-proof device for water conservancy projects, comprising a first clamping member and a second clamping member, the first clamping member and the second clamping member being symmetrically arranged along the center line of the pipeline, a sealing plate being fixedly installed on the inner sides of the first clamping member and the second clamping member, the sealing plate being completely fitted with the inner walls of the first clamping member and the second clamping member, a first side plate being fixedly installed on both sides of the first clamping member, a second side plate being fixedly installed on both sides of the second clamping member, a plurality of fixing bolts being threadedly installed between the first side plate and the second side plate on the same side, the fixing bolts being equidistantly distributed along the length direction of the first side plate and the second side plate, and the first clamping member and the second clamping member being fixed by fixing bolts. This utility model can effectively release the water flow pressure at the leaking part, thereby realizing emergency leak-proofing and facilitating subsequent maintenance.

[0004] Although this device can effectively release the water pressure at the leaking site, thereby achieving emergency plugging, it can only relieve the leaking pressure and cannot completely plug the pipe. Therefore, it cannot completely solve the problem of water conservancy pipeline leakage. Moreover, the fixing bolts used in this device need to be tightened manually. Manual tightening not only causes uneven force on the device and affects the plugging effect, but also increases construction time and affects construction efficiency. In summary, it is necessary to design a new type of water conservancy pipeline plugging device to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to provide a leak-proof device for water conservancy pipelines to solve the problems raised in the above background technology:

[0006] In order to achieve the above purpose, the present invention provides the following technical solutions:

[0007] A leak-proof device for a water conservancy pipeline comprises a symmetrical semicircular steel pipe, a leak-proof cushion fixed in the semicircular steel pipe for leak-proofing, a limiting shaft installed on the left side of the semicircular steel pipe for limiting position, and a clamping mechanism installed on the right side of the semicircular steel pipe for fixing.

[0008] By adopting the above technical solution, using a semicircular steel pipe in combination with a clamping mechanism and using a leak-proof cushion, leaking water conservancy pipelines can be effectively plugged.

[0009] Preferably, the leak-proof gasket includes leak-proof inner gaskets fixed therein at equal intervals, and leak-proof end gaskets fixed at both ends thereof for sealing, and the leak-proof end gaskets are wider than the leak-proof inner gasket.

[0010] By adopting the above technical solution, the relatively wide leak-proof end pads and the equally spaced leak-proof inner pads can be used to double-stop the leaks in the water conservancy pipeline, thereby ensuring the leak-proof effect.

[0011] Preferably, the clamping mechanism includes an upper clamping plate and a lower clamping plate which are symmetrically and horizontally fixed on the right side of the semicircular steel pipe, the lower clamping plate is provided with an extension plate extending downward, and a clamping stud for limiting and fixing is movably provided between the upper clamping plate and the lower clamping plate.

[0012] By adopting the above technical solution, the upper clamping plate and the lower clamping plate can be limited by using the clamping studs, so that the device is pressed tightly against the water conservancy pipeline.

[0013] Preferably, the clamping mechanism also includes a limiting plate fixed to the back of the lower clamping plate, and a clamping nut rotatably limited between the limiting plate and the lower clamping plate. Both ends of the limiting plate are fixedly connected to the extension plate, and the clamping nut is also provided with protruding teeth around its outer periphery.

[0014] By adopting the above technical solution, the rotatable clamping nut can be used to fix the clamping stud when limiting the position.

[0015] Preferably, the clamping mechanism further comprises a threaded rod rotatably passed through the extension plate, the threaded rod is engaged with the convex teeth, and driving wheels for driving the threaded rod to rotate are installed at both ends of the threaded rod.

[0016] By adopting the above technical solution, the rotation of the threaded rod is used to drive the limited rotation of the clamping nut, and the clamping nut and the clamping stud are used to achieve the clamping and leak-proofing of the device.

[0017] Compared with the prior art, the beneficial effects of the present invention are:

[0018] 1) The device of the present application adopts a semicircular steel pipe to compress the leak-proof pad to clamp the water conservancy pipeline to seal the leak. In addition, there are leak-proof inner pads arranged at equal intervals inside the leak-proof pad, and leak-proof end pads wider than the leak-proof inner pads are provided at both ends. The leak-proof end pads and the leak-proof inner pads can be used to double seal the leaking parts of the water conservancy pipeline to ensure the leak-proof effect.

[0019] 2) The device of the present application adopts a driving wheel to limit the semicircular steel pipe through the threaded rod and the clamping nut and the clamping stud to limit the semicircular steel pipe. It is not only convenient to operate, but also the synchronous rotation of the clamping nut can make the semicircular steel pipe be clamped evenly. This design can avoid the uneven clamping force and poor plugging effect. In addition, the driving wheel is used to limit the multiple clamping studs by rotating the clamping nut. Compared with tightening the clamping nuts one by one, it can greatly save construction time and avoid excessive waste of water resources. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] See also Figures 1 to 4 Disclosed is a leak-proof device for water conservancy pipelines, comprising a symmetrical semicircular steel pipe 1, a leak-proof gasket 3 fixed within the semicircular steel pipe 1 for plugging the leak, a limiting shaft 2 mounted on the left side of the semicircular steel pipe 1 for limiting the position, and a clamping mechanism 4 mounted on the right side of the semicircular steel pipe 1 for fixing the leak. The semicircular steel pipe 1, the clamping mechanism 4, and the leak-proof gasket 3 can effectively plug leaking water conservancy pipelines.

[0026] The leak-proof gasket 3 includes leak-proof inner gaskets 32 fixed therein at equal intervals, and leak-proof end gaskets 31 fixed at both ends for sealing. The leak-proof end gaskets 31 are wider than the leak-proof inner gasket 32. The relatively wide leak-proof end gaskets 31 and the leak-proof inner gaskets 32 arranged at equal intervals can double-stop the leak in the water conservancy pipeline, ensuring the leak-proof effect.

[0027] The clamping mechanism 4 includes an upper clamping plate 45 and a lower clamping plate 46 that are symmetrically and horizontally fixed on the right side of the semicircular steel pipe 1. The lower clamping plate 46 is provided with an extension plate 461 extending downward. A clamping stud 44 for limiting and fixing is also movably provided between the upper clamping plate 45 and the lower clamping plate 46. The clamping stud 44 can be used to limit the upper clamping plate 45 and the lower clamping plate 46 so that the device is pressed tightly against the water conservancy pipeline. The clamping mechanism 4 also includes a limiting plate 47 fixed to the back of the lower clamping plate 46 and a clamping nut 43 that is rotatably limited between the limiting plate 47 and the lower clamping plate 46. The two ends of the limiting plate 47 are fixedly connected to the extension plate 461. The clamping nut 43 is also provided with a convex tooth 431 around its outer periphery. The rotatable clamping nut 43 can be used to fix the clamping stud 44 when limiting. The clamping mechanism 4 also includes a threaded rod 41 rotatably inserted through the extension plate 461. The threaded rod 41 engages with the protruding teeth 431. Drive wheels 42 are mounted at both ends of the threaded rod 41 to drive the rotation of the threaded rod 41. The rotation of the threaded rod 41 drives the limited rotation of the clamping nut 43, and the clamping nut 43 and the clamping stud 44 are used to achieve the clamping of the device.

[0028] When implementing the device of the present application, first rotate and unfold the device around the limiting axis 2, then put the device on the corresponding leaking place of the water conservancy pipeline, then pass the clamping stud 44 through the upper clamping plate 45 and the lower clamping plate 46 and insert it into the clamping nut 43 at the corresponding position; then manually rotate the driving wheel 42, the rotating driving wheel 42 drives the threaded rod 41 to rotate, and the rotating threaded rod 41 drives the clamping nut 43 to rotate synchronously through the convex teeth 431, and the rotating clamping nut 43 pushes the lower clamping plate 46 to move upward under the limitation of the clamping stud 44. Under continuous manual rotation, the displaced clamping nut 43 limits the upper clamping plate 45 and the lower clamping plate 46, and the distance between the two is continuously reduced, so that the semicircular steel pipe 1 presses the leak-proof cushion 3 to fit the surface of the pipeline. Under the continuous limitation of the clamping nut 43, the leak-proof inner pad 32 in the leak-proof gasket 3 presses the leaking part of the pipe to achieve the purpose of leak-proofing. The equidistant design of the leak-proof inner pad 32 can limit the leaking part of the pipe between the leak-proof inner pads 32 at different positions, and the leak-proof end pads 31 at both ends of the leak-proof gasket 3 are wider than the leak-proof inner pad 32, which can further perform the leak-proofing work and ensure the leak-proofing effect. In addition, the device of the present application adopts a rotating threaded rod 41 to drive multiple clamping nuts 43 to rotate synchronously, and synchronously shift and limit under the limitation of the clamping stud 44, so that the semicircular steel pipe 1 can be indirectly and evenly stressed, avoiding the situation where the semicircular steel pipe 1 has uneven pressure and fails to achieve the ideal leak-proofing effect. In addition, the device of the present application adopts a driving wheel 42 to achieve the clamping and leak-proofing of the device, which is more convenient to operate. Not only is the clamping force uniform, but it can also reduce the time wasted by tightening the clamping studs 44 one by one, reducing construction time and improving construction efficiency.
