Technical Field
[0001] The utility model relates to the technical field of water conservancy, in particular to a water conservancy pipeline end plugging device. Background Art
[0002] During the maintenance of the pipeline in the water conservancy project, in order to facilitate the continued flow of water to the outside from the cut end of the pipeline, the end of the pipeline needs to be blocked, so a corresponding blocking device needs to be used when blocking the pipeline;
[0003] Most of the existing pipeline plugging devices are simple plugs. In actual use, the plug is inserted into the inner cavity of the end of the pipeline and plugged by interference fit. This method of plugging is likely to cause expansion and deformation of the pipeline, thereby affecting the use effect of the pipeline in the later docking. At the same time, the plug cannot fit the inner wall of the pipeline, resulting in leakage, and the plugging effect is average. Therefore, we propose a water conservancy pipeline end plugging device. Utility Model Content

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a water conservancy pipeline end plugging device, comprising a fixed column, the outer wall of the fixed column is fixedly sleeved with a rubber ring, the outer wall of the fixed column is located on both sides of the rubber ring and is sleeved with limit rings, one of the limit rings is fixedly connected to the outer wall of the fixed column, the outer walls on both sides of the fixed column are provided with sliding grooves, the inner cavity of the sliding groove is rotatably installed with a screw, the outer wall of the screw is sleeved with an adaptive threaded slider, the outer wall of the threaded slider is fixedly connected to the corresponding inner wall of the limit ring, and the outer wall of the limit ring located at one end of the fixed column is fixed with a trumpet-shaped rubber ring.
[0006] By adopting the above technical solution, the device is inserted into the inner cavity of the pipe end, and then the rotating screw can drive the threaded slider to move, thereby driving the corresponding limit ring to move, so that the limit rings on both sides can squeeze the rubber ring, so that the rubber ring can expand, so that the rubber ring can fit the inner wall of the pipe, so as to achieve sealing. At the same time, when the rubber ring is in the pipe, the water flow will impact the inner wall of the rubber ring, thereby exerting pressure on the rubber ring, so that the outer wall of the rubber ring can fit the inner wall of the pipe, so as to achieve re-sealing, improve the sealing effect, avoid leakage, and also avoid deformation of the pipe.
[0007] As a preferred embodiment of the utility model, a cone head is fixedly connected to one end of the fixing column corresponding to the rubber ring.
[0008] By adopting the above technical solution and setting the cone head, the cone head can be used to disperse the water flow when the water flow impacts, so that the water flow can be evenly squeezed on the inner wall of the rubber ring, so that the outer wall of the rubber ring can be evenly pressed against the inner wall of the pipe, ensuring the sealing effect.
[0009] As a preferred embodiment of the utility model, a catheter runs through the inner cavity of the fixed column, one end of the catheter is connected to the rubber ring, the outer end of the catheter is connected to a one-way valve, and the outer end of the one-way valve is fixedly connected to an external air pipe.
[0010] By adopting the above technical solution, before the rubber ring is squeezed, gas is introduced into the conduit through the external air pipe, so that the gas enters the rubber ring, so that the rubber ring collides and initially fits against the inner wall of the pipe to form a preliminary blockage.
[0011] As a preferred embodiment of the utility model, a connecting rod is fixed to one end of the fixing column, and a handle is fixedly connected to the outer end of the connecting rod.
[0012] By adopting the above technical solution and setting the handle, it is convenient to hold the handle to operate the device.
[0013] As a preferred implementation of the utility model, a matching rubber pad is fixedly glued to a side wall of the limiting ring corresponding to the rubber ring.
[0014] By adopting the above technical solution and providing the rubber pad, the limiting ring can avoid causing wear to the rubber ring when squeezing the rubber ring.
[0015] As a preferred embodiment of the present utility model, the outer end of the screw rod movably passes through the fixed column and is fixedly connected with a rotating block.
[0016] By adopting the above technical solution and setting the rotating block, the screw rod can be driven to rotate by rotating the rotating block, thereby facilitating operation.
[0017] Compared with the prior art, the beneficial effects of the utility model are as follows:
[0018] The technical solution of the present application is a water conservancy pipeline end plugging device. After the device is inserted into the inner cavity of the pipeline, gas is introduced into the conduit through an external air pipe, and then the gas enters the rubber ring, so that the rubber ring expands and fits the inner wall of the pipeline, thereby ensuring the plugging effect. At the same time, the rotating screw can drive the threaded slider to move, and then the movable limit ring can apply pressure to the rubber ring again, so that it expands again, thereby improving the plugging effect again, effectively avoiding leakage, and also avoiding pipeline deformation;
[0019] A trumpet-shaped rubber ring is fixed on a fixed limiting ring, so that after water impacts the cone head, the water can be dispersed to the inner wall of the rubber ring opening, so that under the impact of water pressure, the outer wall of the trumpet-shaped rubber ring can be pressed tightly against the inner wall of the pipe, thereby further improving the sealing effect.

[0027] See also Figure 1-3 The utility model provides a technical solution: a water conservancy pipeline end plugging device, comprising a fixed column 1, the outer wall of the fixed column 1 is fixedly sleeved with a rubber ring 2, the outer wall of the fixed column 1 is located on both sides of the rubber ring 2 and is sleeved with a limit ring 18, one of the limit rings 18 is fixedly connected to the outer wall of the fixed column 1, the outer walls of both sides of the fixed column 1 are provided with a slide groove 14, the inner cavity of the slide groove 14 is rotatably installed with a screw rod 15, the outer wall of the screw 15 is sleeved with an adaptive threaded slider 17, the outer wall of the threaded slider 17 is fixedly connected to the corresponding inner wall of the limit ring 18, and the outer wall of the limit ring 18 at one end of the fixed column 1 is fixed with a trumpet-shaped rubber ring 12;
[0028] In actual use, the device is inserted into the inner cavity of the pipe end, and then the screw 15 is rotated to drive the threaded slider 17 to move, thereby driving the corresponding limit ring 18 to move, so that the limit rings 18 on both sides can squeeze the rubber ring 2, so that the rubber ring 2 can expand, so that the rubber ring 2 can fit the inner wall of the pipe, so as to achieve blocking. At the same time, when the rubber ring 12 is in the pipe, the water flow will impact the inner wall of the rubber ring 12, thereby applying pressure to the rubber ring 12, so that the outer wall of the rubber ring 12 can fit the inner wall of the pipe, so as to achieve re-blocking, improve the blocking effect, avoid leakage, and also avoid deformation of the pipe;
[0029] Furthermore, a conduit 21 runs through the inner cavity of the fixed column 1, one end of the conduit 21 is connected to the rubber ring 2, the outer end of the conduit 21 is connected to a one-way valve 22, and the outer end of the one-way valve 22 is fixedly connected to an external air pipe 23;
[0030] Before the rubber ring 2 is squeezed, gas is introduced into the conduit 21 through the external gas pipe 23, so that the gas enters the rubber ring 2, so that the rubber ring 2 can collide and initially fit against the inner wall of the pipe to form a preliminary blockage;
[0031] Furthermore, a connecting rod 13 is fixed to one end of the fixed column 1, and a handle 19 is fixedly connected to the outer end of the connecting rod 13. The setting of the handle 19 makes it convenient to hold the handle 19 to operate the device;
[0032] It is worth mentioning that the outer end of the screw rod 15 movably penetrates the fixed column 1 and is fixedly connected with a rotating block 16. The setting of the rotating block 16 enables the screw rod 15 to rotate by rotating the rotating block 16, thereby making the operation convenient;

The setting of the cone head 11 allows the cone head 11 to disperse the water flow when the water flow impacts, so that the water flow can be evenly squeezed on the inner wall of the rubber ring 12, so that the outer wall of the rubber ring 12 can be evenly pressed against the inner wall of the pipe, ensuring the sealing effect.
[0035] The implementation principle of the water conservancy pipeline end plugging device of the present application is as follows: in actual use, the device is inserted into the inner cavity of the pipeline end, and then the rotating screw 15 can drive the threaded slider 17 to move, thereby driving the corresponding limit ring 18 to move, so that the limit rings 18 on both sides can squeeze the rubber ring 2, so that the rubber ring 2 can expand, so that the rubber ring 2 can fit the inner wall of the pipeline, thereby achieving plugging. At the same time, when the rubber ring 12 is in the pipeline, the cone head 11 can be used to disperse the water flow when the water flow impacts, so that the water flow can be evenly squeezed on the inner wall of the rubber ring 12, so that the outer wall of the rubber ring 12 can be evenly pressed against the inner wall of the pipeline, thereby applying pressure to the rubber ring 12, so that the outer wall of the rubber ring 12 can fit the inner wall of the pipeline, thereby achieving re-plugging, improving the plugging effect, avoiding leakage, and also avoiding deformation of the pipeline.
