Description

Technical Field

[0001] This application relates to the field of water conservancy leak sealing and diversion technology, specifically a leak sealing and diversion device for water conservancy project management. Background Technology

[0002] Leak-stopping and diversion devices in water conservancy project management are crucial equipment for ensuring the structural safety and normal function of water conservancy projects. These devices are typically designed to detect and repair leaks in water conservancy projects and guide water flow to designated drainage systems to prevent flooding and water resource loss.

[0003] Chinese utility model patent CN221142653U discloses a reservoir leak-stopping and diversion device. This device integrates diversion and sealing functions. Through the coordinated work of components such as a shell, movable sealing plate, through hole, protrusion, diversion port, spring, and through groove, when the underground river water resources are abundant, the natural pressure of the underground water drives the sealing plate to open, allowing water to flow through the through groove into the shell, and then smoothly divert to the reservoir through the through hole. Conversely, when the underground river water resources decrease, the spring automatically resets, pushing the sealing plate to tightly seal the diversion port and prevent water loss. However, the shell is installed at the inlet and outlet of the groundwater through the installation port. Since the shape of the inlet and outlet is usually irregular, grouting material is usually used to fix the installation port. However, manual filling of grouting material is difficult to operate quickly, thus making it impossible to quickly fix the installation port.

[0004] Therefore, this application provides a leak-stopping and diversion device for water conservancy project management to solve the above-mentioned problems. Utility Model Content

[0005] This application provides a leak-stopping and diversion device for water conservancy project management, which aims to solve the problem of difficulty in quickly installing existing installation ports and inlets / outlets as mentioned in the background art.

[0006] To achieve the above objectives, this application provides the following technical solution: a leak-stopping and diversion device for water conservancy project management, comprising a leak-stopping sleeve, a fixed ring plate located on the outer wall of one end of the leak-stopping sleeve, a sealing ring plate fixedly installed on the inner side of one end of the leak-stopping sleeve, and an overlapping annular groove formed on the sealing ring plate at the inner end of the leak-stopping sleeve. A sealing plate is provided on the inner side of the sealing ring plate, and an overlapping plate adapted to the overlapping annular groove is fixedly installed on one end of the sealing plate. A support mechanism is symmetrically arranged between the end of the overlapping plate away from the sealing plate and the inner wall of the leak-stopping sleeve.

[0007] The leak-sealing sleeve has symmetrically symmetrical grouting holes on its outer wall at the side of the fixed ring plate. A rubber airbag is fixedly installed on the outer wall of the leak-sealing sleeve between the two fixed ring plates. An air nozzle is provided on the rubber airbag, with the end of the nozzle away from the rubber airbag passing through the fixed ring plate. An inner cavity is formed inside the sealing plate and the overlapping plate, and a limiting mechanism is provided on the inner side of the inner cavity. When using the leak-sealing sleeve, the rubber airbag and grouting holes work together to initially fix the leak-sealing sleeve before subsequent grouting, allowing for rapid installation and immediate use.

[0008] Preferably, the limiting mechanism includes a plurality of guide sleeves arranged in a circular array and fixedly installed on the inner wall of the inner cavity, a pin slidably installed inside the guide sleeves, and an adjusting screw passing through the overlapping plate. A connecting plate is rotatably mounted on one end of the adjusting screw located inside the inner cavity. A plurality of transmission rods arranged in a circular array are rotatably mounted on the bottom surface of the connecting plate. The end of the transmission rod away from the connecting plate is rotatably connected to the pin, and the end of the pin away from the transmission rod passes through the sealing plate. When the sealing plate is fixed, rotating the adjusting screw drives the pin, causing it to extend out of the inner cavity to fix the sealing plate, facilitating grouting.

[0009] Preferably, the inner wall of the sealing ring plate has a plurality of pin holes arranged in a ring array to fit the pin rod. When the pin rod is fitted, it can enter the pin hole when it extends out of the inner cavity to fix the sealing plate.

[0010] Preferably, the support mechanism includes a guide groove formed on the inner wall of the sealing sleeve, a connecting frame slidably installed inside the guide groove, and a support spring fixedly installed between the connecting frame and the inner wall of the guide groove. The end of the connecting frame away from the guide groove is fixedly connected to the overlapping plate. During routine use of the sealing plate for sealing, the cooperation of the support spring and the connecting piece allows the sealing plate to be positioned within the sealing ring plate for sealing when the groundwater pressure is insufficient.

[0011] Preferably, the outer walls of both fixing ring plates are provided with a plurality of clearance grooves arranged in a circular array, and two of the clearance grooves located at the same position are provided with a reinforcing mechanism on their inner sides. During the initial fixing of the sealing sleeve, the use of the reinforcing mechanism makes the initial fixing of the sealing sleeve more secure, facilitating subsequent steps.

[0012] Preferably, the reinforcement mechanism includes a guide rod slidably mounted inside the relief groove, a support plate fixedly mounted at one end of the guide rod located outside the relief groove, and a plurality of spiked rods arranged in a linear array fixedly mounted at the end of the support plate away from the guide rod. When used in conjunction with a rubber airbag, the expansion of the rubber airbag allows the spiked rods to be inserted into the inner wall of the groundwater inlet / outlet, ensuring a more secure initial fixation of the sealing sleeve.

[0013] This water conservancy project management leak-stopping and diversion device has a simple structure and is easy to use. Through the rapid inflation and expansion of the rubber air bladder, it can quickly and initially seal the groundwater inlet and outlet, and can also support and fix the leak-stopping sleeve for grouting treatment to further strengthen the leak-stopping effect. It is suitable for various complex geological environments and leak-stopping needs. At the same time, the sealing plate can be flexibly opened and closed through the cooperation of the support mechanism and the limiting mechanism, enabling rapid diversion and sealing.

[0021] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0022] Example 1

[0023] This embodiment provides a leak-stopping and diversion device for water conservancy project management, such as... Figure 1-5 As shown, the leak sealing and drainage device includes a leak sealing sleeve 1, a fixed ring plate 11 located on the outer side wall of one end of the leak sealing sleeve 1, a sealing ring plate 2 fixedly installed on the inner side of one end of the leak sealing sleeve 1, and an overlapping annular groove 21 opened on the sealing ring plate 2 at the inner end of the leak sealing sleeve 1. A sealing plate 3 is provided on the inner side of the sealing ring plate 2. An overlapping plate 31 adapted to the overlapping annular groove 21 is fixedly installed on one end of the sealing plate 3. A support mechanism 32 is symmetrically arranged between the end of the overlapping plate 31 away from the sealing plate 3 and the inner side wall of the leak sealing sleeve 1.

[0024] The sealing sleeve 1 has symmetrical grouting holes 12 on its outer wall at the side of the fixed ring plate 11. A rubber airbag 4 is fixedly installed on the outer wall of the sealing sleeve 1 at the position between the two fixed ring plates 11. An air nozzle 41 is provided on the rubber airbag 4. The end of the air nozzle 41 away from the rubber airbag 4 passes through the fixed ring plate 11. An inner cavity is formed inside the sealing plate 3 and the overlapping plate 31. A limit mechanism 33 is provided on the inner side of the inner cavity.

[0025] In use, initially, under the action of the support mechanism 32, the sealing plate 3 and the overlapping plate 31 are located inside the sealing ring plate 2 and the overlapping annular groove 21, respectively. The sealing plate 3 and the overlapping plate 31 are fixed by the limiting mechanism 33, so that the plugging sleeve 1 is in a blocked state. Then, one end of the plugging sleeve 1 with the fixing ring plate 11 can be inserted into the inside of the groundwater inlet and outlet, and the air nozzle 41 can be connected to the external air pipe. The air pipe can be inflated into the rubber air bag 4 through the air nozzle 41. After the rubber air bag 4 is inflated, it can seal the groundwater inlet and outlet, thus performing the initial installation of the plugging sleeve 1. Then, the end of the plugging sleeve 1 away from the rubber air bag 4 is connected to the high-pressure grouting machine. The high-pressure grouting machine injects polyurethane and other materials into the gap between the plugging sleeve 1 and the inlet and outlet through the grouting hole 12, thus completing the installation of the plugging sleeve 1.

[0026] Specifically, the limiting mechanism 33 includes a plurality of guide sleeves 331 fixedly installed in a ring array on the inner wall of the inner cavity, a pin 332 slidably installed inside the guide sleeves 331, and an adjusting screw 333 passing through the overlapping plate 31. A connecting plate 334 is rotatably mounted on one end of the adjusting screw 333 located inside the inner cavity. A plurality of transmission rods 335 arranged in a ring array are rotatably mounted on the bottom surface of the connecting plate 334. The end of the transmission rod 335 away from the connecting plate 334 is rotatably connected to the pin 332, and the end of the pin 332 away from the transmission rod 335 passes through the sealing plate 3. The mechanism also includes a limiting mechanism for the sealing plate 3 and the overlapping plate 31. When the connecting plate 31 is fixed, the adjusting screw 333 can be rotated. The adjusting screw 333 is screwed to the through-hole of the overlapping plate 31. Therefore, when rotating, it can move along the through-hole and push the connecting plate 334. The two ends of the transmission rod 335 are rotatably connected to the connecting plate 334 and the pin 332 respectively. Therefore, when the connecting plate 334 moves, the transmission rod 335 can drive the pin 332 to slide along the guide sleeve 331, so that the pin 332 slides out of the sealing plate 3 to complete the fixing of the sealing plate 3 and the overlapping plate 31. When the adjusting screw 333 is reversed, the pin 332 can be driven to slide in the opposite direction along the guide sleeve 331 into the inner cavity, which can release the fixing of the sealing plate 3 and the overlapping plate 31.

[0027] Furthermore, the inner wall of the sealing ring plate 2 is provided with a plurality of pin holes 22 arranged in a ring array to fit the pin rod 332; when the pin rod 332 extends out of the sealing plate 3, it can enter the pin holes 22 to fix the sealing plate 3.

[0028] More specifically, the support mechanism 32 includes a guide groove 321 formed on the inner wall of the plugging sleeve 1, a connecting frame 322 slidably installed inside the guide groove 321, and a support spring 323 fixedly installed between the connecting frame 322 and the inner wall of the guide groove 321. The end of the connecting frame 322 away from the guide groove 321 is fixedly connected to the overlapping plate 31. After the plugging sleeve 1 is installed, the end of the plugging sleeve 1 away from the rubber airbag 4 can be connected to the diversion pipe, and the restriction on the sealing plate 3 can be released. At this time, the groundwater can lift the sealing plate 3 under the action of water pressure, so that it slides along the guide groove 321 through the connecting frame 322. The sealing plate 3 can be separated from the sealing ring plate 2. At this time, the groundwater can be discharged to the outside through the plugging sleeve 1 and the diversion pipe. After the drainage is completed, the connecting frame 322 and the sealing plate 3 can slide back to reset under the action of the support spring 323 to seal.

[0029] Example 2

[0030] Unlike Embodiment 1, when the groundwater pressure is high, the rubber airbag 4 may not be able to firmly fix the plugging sleeve 1. Therefore, the outer walls of the two fixing ring plates 11 are provided with a number of relief grooves 5 arranged in a ring array. The inner sides of the two relief grooves 5 located at the same position are provided with a reinforcement mechanism 51.

[0031] In use, by setting a reinforcing mechanism 51 on the fixed ring plate 11, the rubber airbag 4 can be lifted up when it is inflated by the air nozzle 41. The reinforcing mechanism 51 can be connected to the inner wall of the groundwater inlet and outlet to further strengthen the initial fixation of the plugging sleeve 1 so that grouting can be carried out later.

[0032] Specifically, the reinforcement mechanism 51 includes a guide rod 511 slidably installed inside the relief groove 5, a support plate 512 fixedly installed at one end of the guide rod 511 located outside the relief groove 5, and a plurality of barbs 513 fixedly installed at one end of the support plate 512 away from the guide rod 511 in a linear array. When the rubber airbag 4 is inflated, it can lift the support plate 512, so that the guide rod 511 slides out of the relief groove 5. When the support plate 512 contacts the inner wall of the groundwater inlet / outlet, the barbs 513 on it can be inserted into the inner wall for fixation.

[0033] The above description is merely a preferred embodiment of this application, but the scope of protection of this application is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this application, based on the technical solution and concept of this application, should be included within the scope of protection of this application.
