Description

Technical Field

[0001] This utility model relates to the field of water conservancy construction technology, and in particular to a seepage prevention structure for water conservancy construction pipelines. Background Technology

[0002] Water conservancy projects are engineering projects constructed to control and regulate surface water and groundwater in nature to achieve the purpose of eliminating harm and promoting benefits. Pipelines are the most widely used component in water conservancy projects. Pipelines can transport water from areas with abundant water resources to areas with scarce water resources. When using pipelines, multiple pipelines usually need to be connected, and seepage-proof structures are installed at the connection points to prevent water leakage.

[0003] A search revealed that the Chinese patent "Anti-seepage Structure for Water Conservancy Construction Pipelines" (authorization announcement number CN221171322U) involves setting an airbag in an annular groove on the surface of the inner pipe, and placing an anti-seepage pad on the surface of the airbag. By inflating the airbag with an air pump, the anti-seepage pad is tightly attached to the joints of the protective pipe, the water supply pipe, and the drain pipe, preventing leakage at the joints. This solves the problem of simple pipeline anti-seepage structures that use sealing rings to seal the joints, which are prone to aging over time, leading to poor sealing and leakage at the pipe connections.

[0004] While the use of geotextile gaskets in the aforementioned applications can achieve a sealing and seepage prevention effect, the geotextile gaskets are one-piece designs. During the sealing process, prolonged contact with aqueous solutions makes the one-piece geotextile gaskets susceptible to corrosion, which affects their sealing effect on the pipeline and results in poor seepage prevention.

[0005] Therefore, a seepage prevention structure for water conservancy construction pipelines is proposed to solve the above problems. Utility Model Content

[0006] The purpose of this utility model is to provide a seepage prevention structure for water conservancy construction pipelines to solve the above-mentioned problems. It improves the problem that the integrated seepage prevention gasket is easily corroded as a whole during the sealing process due to prolonged contact with aqueous solution, which affects the sealing effect of the seepage prevention gasket on the pipeline and results in poor seepage prevention.

[0007] This utility model achieves the above-mentioned objective through the following technical solution: a seepage prevention structure for water conservancy construction pipelines, comprising: two water pipes, each of which is fixedly connected to a flange, the two flanges being fixed by bolts and nuts; and a seepage prevention mechanism, which includes a sealing ring fixedly connected to one end of one of the flanges, a fixing ring fixedly connected to one end of the other flange, a sealing groove fixedly connected to the other end of the fixing ring, an annular plate slidably connected to the inner wall of the sealing groove, a plurality of annular frames slidably connected to one end of the annular plate, a sealing ring fixedly connected to one end of each of the plurality of annular frames, a first annular groove formed on the outer surface of the sealing ring, and a second annular groove formed on the inner surface of the sealing ring.

[0008] Preferably, the seepage prevention mechanism further includes a water bladder fixedly connected to one end of the inner wall of the annular frame. A circular tube is connected to the surface of the water bladder, and the other end of the circular tube extends through the annular frame and communicates with a corresponding second annular groove. This facilitates the collection of small amounts of leaked aqueous solution, and the collected aqueous solution helps the water bladder expand, causing the annular frame to push the corresponding sealing ring towards the sealing ring, strengthening the sealing force between the sealing ring and the sealing ring, thereby enhancing the sealing effect of the sealing ring and preventing further leakage of aqueous solution.

[0009] Preferably, a one-way valve is installed on the surface of the circular tube, and the one-way valve is located inside the annular frame. This helps to make the circular tube a one-way tube, preventing the aqueous solution entering the water bladder from flowing back into the second annular groove.

[0010] Preferably, a slider is fixedly connected to the other end of the annular frame, and the surface of the slider is slidably connected to the inner wall of the annular plate. This facilitates limiting the movement path of the annular frame.

[0011] Preferably, a rubber ring is fixedly connected to the inner edge of the retaining ring, and the inner diameter of the rubber ring is the same as the outer diameter of the water pipe. This enhances the sealing performance between the water pipe and the retaining ring.

[0012] Preferably, a sliding plate is slidably connected to the lower end of the inner wall of the fixing ring, the top end of the sliding plate is fixedly connected to the lower end of the surface of the annular plate, and a threaded rod is threadedly connected to the inner wall of the sliding plate. This facilitates the fixing of the position of the annular plate and ensures the stability of the device during use.

[0013] Preferably, the inner wall of the second annular groove is inclined. This facilitates better passage of the aqueous solution in the second annular groove into the water bladder through the circular tube.

[0014] The beneficial effects of this utility model are:

[0015] 1. After the two water pipes are installed in the above-mentioned anti-seepage mechanism, the sealing operation at the connection of the two water pipes is facilitated by the action of multiple sealing rings. When a small amount of aqueous solution seeps out from the connection of the two water pipes, the seeping aqueous solution is collected by the action of the first annular groove, the second annular groove and the water bladder. The collected aqueous solution helps to expand the water bladder and push the corresponding sealing ring towards the sealing ring, strengthening the sealing force between the sealing ring and the sealing ring, thereby strengthening the sealing effect of the sealing ring and preventing the aqueous solution from continuing to seep out. Multiple sealing layers are formed by multiple sealing rings, which helps to strengthen the sealing effect at the connection of the two water pipes and prevent aqueous solution leakage.

[0016] 2. By setting a one-way valve, the circular tube is made into a one-way tube, which prevents the aqueous solution entering the water bladder from flowing back into the second annular groove, thus ensuring the stability of the device during use. Attached Figure Description

Detailed Implementation

[0024] 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.

[0025] In practical implementation: such as Figures 1-6As shown, the seepage prevention structure for water conservancy construction pipelines includes: two water pipes 100, each of which is fixedly connected to a flange 200 by bolts and nuts; and a seepage prevention mechanism 300, which includes a sealing ring 310 fixedly connected to one end of one flange 200, a fixing ring 320 fixedly connected to one end of the other flange 200, a sealing groove 330 fixedly connected to the other end of the fixing ring 320, an annular plate 340 slidably connected to the inner wall of the sealing groove 330, a plurality of annular frames 350 slidably connected to one end of the annular plate 340, a sealing ring 360 fixedly connected to one end of each of the plurality of annular frames 350, a first annular groove 361 formed on the outer surface of the sealing ring 360, and a second annular groove 362 formed on the inner surface of the sealing ring 360.

[0026] In this embodiment, one end of one water pipe 100 is on the same vertical plane as the other end of the sealing ring 310, and one end of the other water pipe 100 is on the same vertical plane as the other end of the sealing ring 360. There is a gap between two adjacent sealing rings 360. When the two water pipes 100 are installed, the sealing ring 310 enters the sealing groove 330. At this time, the surface of the sealing ring 310 is in contact with the inner wall of the sealing groove 330, and when the opposite ends of the two water pipes 100 are pressed together, the other end of the sealing ring 310 is pressed together with multiple sealing rings 360. At the same time, multiple annular frames 350 are pressed together with the opposite ends of the annular plate 340. After installation, the connection between the multiple sealing rings 360 and the two water pipes 100 is on the same vertical plane.

[0027] like Figure 4 , Figure 5 and Figure 6 As shown, the seepage prevention mechanism 300 also includes a water bladder 351 fixedly connected to one end of the inner wall of the annular frame 350. A circular tube 352 is connected to the surface of the water bladder 351, and the other end of the circular tube 352 extends through the annular frame 350 and communicates with the corresponding second annular groove 362. A one-way valve 353 is installed on the surface of the circular tube 352, and the one-way valve 353 is located inside the annular frame 350. The inner wall of the second annular groove 362 is inclined.

[0028] In this embodiment, when the device is in its initial state, the water bladder 351 is contracted within the corresponding annular frame 350, and the surface of the water bladder 351 is in contact with one end of the annular plate 340. When an aqueous solution enters the water bladder 351, the water bladder 351 will gradually expand. When the water bladder 351 expands, it will squeeze the annular frame 350 to move under the action of the annular plate 340, and the annular frame 350 will push the corresponding sealing ring 360 to move towards the sealing ring 310, thereby strengthening the force of the sealing ring 360 and the sealing ring 310 to press against each other.

[0029] An installation groove is provided on the inner wall of the annular frame 350. A one-way valve 353 is installed in the installation groove. The round tube 352 becomes a one-way tube under the action of the one-way valve 353. The aqueous solution in the second annular groove 362 can only enter the water bag 351 through the round tube 352 from the second annular groove 362.

[0030] like Figure 6 As shown, a slider 354 is fixedly connected to the other end of the annular frame 350, and the surface of the slider 354 is slidably connected to the inner wall of the annular plate 340.

[0031] In this embodiment, the inner wall of the annular frame 350 is provided with a groove that matches the slider 354. The surface of the slider 354 is slidably connected to the inner wall of the groove. The interaction between the groove and the slider 354 limits the movement of the annular plate 340.

[0032] like Figure 3 As shown, a rubber ring 321 is fixedly connected to the inner edge of the fixing ring 320, and the inner diameter of the rubber ring 321 is the same as the outer diameter of the water pipe 100.

[0033] In this embodiment, after the two water pipes 100 are installed, the inner surface of the rubber ring 321 is in contact with the surface of the other water pipe 100, thereby enhancing the sealing effect.

[0034] like Figure 6 As shown, a sliding plate 322 is slidably connected to the lower end of the inner wall of the fixed ring 320. The top end of the sliding plate 322 is fixedly connected to the lower end of the surface of the annular plate 340. A threaded rod 323 is threadedly connected to the inner wall of the sliding plate 322.

[0035] In this embodiment, the inner wall of the fixing ring 320 is provided with a moving groove that matches the sliding plate 322, and the lower end of the inner wall of the fixing ring 320 is provided with a threaded hole that matches the threaded rod 323. In the initial state, the threaded rod 323 is threadedly connected to the threaded hole, thereby fixing the annular plate 340 and pressing the annular plate 340 against the opposite end of the sealing groove 330.

[0036] When the sealing ring 360 and water bladder 351 need to be replaced, disconnect the threaded rod 323 from the threaded hole, remove the annular plate 340 from the sealing groove 330, and then remove and replace the annular frame 350, which increases the practicality of the device.

[0037] In use, the sealing ring 310 is inserted into the sealing groove 330, and the two flanges 200 are installed using bolts and nuts. After installation, the opposite ends of the two water pipes 100 are pressed together, and the other end of the sealing ring 310 is pressed together with multiple sealing rings 360. During use, the multiple sealing rings 360 seal the two water pipes 100. During prolonged sealing, when a small amount of aqueous solution leaks from the connection between the two water pipes 100, the aqueous solution will first enter the sealing ring 360 near the connection between the two water pipes 100. Under the action of the gap between two adjacent sealing rings 360, the aqueous solution will first enter the first annular groove 361 and the second annular groove 362 on the surface of the corresponding sealing ring 360, entering the first annular groove. The aqueous solution in 361 will fall into the second annular groove 362 of the adjacent sealing ring 360. The aqueous solution entering the second annular groove 362 will enter the corresponding water bladder 351 through the circular tube 352. When the aqueous solution enters the water bladder 351, the water bladder 351 will gradually expand. When the water bladder 351 expands, it will squeeze the annular frame 350 under the action of the annular plate 340 and move it. The annular frame 350 will push the corresponding sealing ring 360 towards the sealing ring 310, strengthening the sealing force between the sealing ring 360 and the sealing ring 310, thereby strengthening the sealing effect of the sealing ring 360. According to the above principle, multiple sealing rings 360 will form multiple sealing layers, thereby strengthening the sealing effect at the connection of the two water pipes 100 and preventing the aqueous solution from leaking.

[0038] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can be appropriately combined to form other embodiments that can be understood by those skilled in the art. 。
