Description

Technical Field

[0001] This utility model relates to the technical field of seepage sealing devices, and in particular to a seepage sealing device for reservoir dams. Background Technology

[0002] Leakage sealing devices for reservoir dams are designed to prevent or reduce leakage, thereby ensuring the stability of the dam and the safety of the reservoir. The design and use of these devices involve multiple technical approaches, the specific selection and implementation of which depend on factors such as the type of dam, the location of the leakage, and the degree of leakage.

[0003] In existing dam seepage sealing devices, most methods involve pouring cement or grouting material into the seepage area. However, the sealing material will flow along the dam surface, resulting in poor sealing effect and waste of unrestricted sealing material, which affects its embedding effect. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a seepage sealing device for reservoir dams.

[0005] This utility model is achieved by the following technical solution: a seepage sealing device for reservoir dams, including a sealing top plate, a filling component at the bottom of the sealing top plate, and a connecting component inside the sealing top plate.

[0006] The filling assembly includes a sealing screw, the outer wall of which is slidably connected to the inner wall of a sealing top plate. The top of the sealing top plate is connected to a material inlet. A limiting groove is formed at the bottom of the sealing top plate. A limiting push plate is slidably connected to the inner wall of the limiting groove. An avoidance hole is formed at the top of the limiting push plate. A spring limiting rod is slidably connected to the inner wall of the avoidance hole. The top of the spring limiting rod is fixedly connected to the top of the inner wall of the limiting groove. A limiting spring is fixedly connected to the top of the limiting push plate. The end of the limiting spring away from the limiting push plate is fixedly connected to the top of the inner wall of the limiting groove.

[0007] As a further improvement to the above solution, four sealing screws are provided, four clearance holes are provided, the four clearance holes are symmetrically arranged around the center of the sealing top plate, and four spring limiting rods are provided.

[0008] The above technical solution involves driving the sealing screw into the surface of the reservoir dam, which in turn pulls the sealing top plate toward the dam, causing the sealing top plate to press down on the limiting push plate. The limiting push plate then slides upward along the limiting groove, while the spring limiting rod slides along the clearance hole opened on the limiting push plate.

[0009] As a further improvement to the above solution, the connecting assembly includes a second sealing top plate, the outer wall of which is in contact with the surface of the sealing top plate, a connecting groove is provided on the right side of the sealing top plate, and an avoidance groove is provided on the inner wall of the second sealing top plate, with a connecting pin slidably connected to the inner wall of the avoidance groove.

[0010] As a further improvement to the above solution, the outer wall of the connecting pin is slidably connected to the inner wall of the connecting groove, the inner wall of the connecting groove is provided with a second limiting groove, the inner wall of the second limiting groove is slidably connected with a limiting slider, and the top of the second limiting groove is provided with an avoidance groove.

[0011] As a further improvement to the above solution, two limiting sliders are provided, and the two limiting sliders are symmetrically arranged with the inlet as the center. Four connecting slides are provided, and the four connecting slides are symmetrically arranged with the center of the sealing top plate.

[0012] As a further improvement to the above solution, an unlocking block is fixedly connected to the top of the limiting slider, the outer wall of the unlocking block is slidably connected to the inner wall of the clearance groove, and a limiting spring is fixedly connected to the end of the limiting slider away from the connecting pin.

[0013] As a further improvement to the above solution, four unlocking blocks are provided, which are symmetrically arranged around the center of the sealing top plate. Two limit springs are provided, which are symmetrically arranged around the connecting pin.

[0014] Through the above technical solution, the connecting pin is slidably installed along the clearance groove opened in the second sealing plate, so that the connecting pin drives the second sealing plate to slide into the connecting groove opened in the sealing plate. At the same time, the connecting pin will press the limiting slider to both sides, so that the limiting slider drives the unlocking block to slide along the clearance groove.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] This invention involves driving a sealing screw into the surface of a reservoir dam, which pulls the sealing top plate towards the dam. This causes the sealing top plate to press down on a limiting push plate, which slides upward along a limiting groove. Simultaneously, a spring limiting rod slides along an avoidance hole on the limiting push plate, while the limiting push plate compresses the limiting spring upward. The spring, in turn, pushes the limiting push plate against the dam surface under its reaction force. Then, sealing material is injected into the sealing top plate through the inlet, preventing the sealing material from leaking out and ensuring the quality of the sealing and solidification process.

[0017] This invention involves sliding a connecting pin along a clearance groove in the sealing top plate 2. This causes the connecting pin to slide the sealing top plate 2 into the clearance groove. Simultaneously, the connecting pin presses against limiting sliders on both sides, causing the limiting sliders to slide along the clearance groove with the unlocking block. At the same time, the limiting sliders compress limiting springs inside the limiting groove 2. When the limiting sliders disengage from the connecting pin surface, the limiting springs push the limiting sliders, causing them to engage in the groove of the connecting pin, thus limiting the connection of the connecting pins and the sealing top plate 2, thereby connecting them and enabling longer sealing operations.

[0026] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments. Example

[0027] Please combine Figure 1-6This embodiment of a seepage sealing device for a reservoir dam includes a sealing top plate 1, a filling component 2 at the bottom of the sealing top plate 1, and a connecting component 3 inside the sealing top plate 1.

[0028] The filling component 2 includes a sealing screw 201, the outer wall of which is slidably connected to the inner wall of the sealing top plate 1. The top of the sealing top plate 1 is connected to a feed inlet 202. The bottom of the sealing top plate 1 is provided with a limiting groove 203. The inner wall of the limiting groove 203 is slidably connected to a limiting push plate 204. The top of the limiting push plate 204 is provided with a clearance hole 205. The inner wall of the clearance hole 205 is slidably connected to a spring limiting rod 206. The top of the spring limiting rod 206 is fixedly connected to the top of the inner wall of the limiting groove 203. The top of the limiting push plate 204 is fixedly connected to a limiting spring 207. The end of the limiting spring 207 away from the limiting push plate 204 is fixedly connected to the top of the inner wall of the limiting groove 203.

[0029] There are four sealing screws 201 and four clearance holes 205. The four clearance holes 205 are symmetrically arranged around the center of the sealing top plate 1. There are four spring limit rods 206.

[0030] The connecting component 3 includes a second sealing top plate 301. The outer wall of the second sealing top plate 301 is in contact with the surface of the sealing top plate 1. A connecting groove 302 is provided on the right side of the sealing top plate 1. An avoidance groove 303 is provided on the inner wall of the second sealing top plate 301. A connecting pin 304 is slidably connected to the inner wall of the avoidance groove 303.

[0031] The outer wall of the connecting pin 304 is slidably connected to the inner wall of the connecting groove 302. The inner wall of the connecting groove 302 is provided with a second limiting groove 305. The inner wall of the second limiting groove 305 is slidably connected to a limiting slider 306. The top of the second limiting groove 305 is provided with an avoidance groove 307.

[0032] There are two limit sliders 306, which are symmetrically arranged with the feed inlet 202 as the center. There are four connecting grooves 302, which are symmetrically arranged with the sealing top plate 1 as the center.

[0033] The top of the limiting slider 306 is fixedly connected to the unlocking block 308. The outer wall of the unlocking block 308 is slidably connected to the inner wall of the clearance groove 307. The end of the limiting slider 306 away from the connecting pin 304 is fixedly connected to the limiting spring 309.

[0034] There are four unlocking blocks 308, which are symmetrically arranged around the center of the sealing top plate 1. There are two limit springs 309, which are symmetrically arranged around the connecting pin 304.

[0035] The implementation principle of a seepage sealing device for a reservoir dam in this embodiment is as follows: A sealing screw 201 is driven into the surface of the reservoir dam, causing the screw 201 to pull the sealing top plate 1 towards the dam. This causes the sealing top plate 1 to press down on the limiting push plate 204, which slides upward along the limiting groove 203. Simultaneously, a spring limiting rod 206 slides along the clearance hole 205 of the limiting push plate 204. The limiting push plate 204 also compresses the limiting spring 207 upward, causing the limiting spring 207 to push the limiting push plate 204 against the dam surface under its reaction force. Then, sealing material is injected into the sealing top plate 1 through the inlet 202 to prevent material loss and ensure quality during the sealing and solidification process. Finally, the connecting pin 304 is moved along the sealing top plate 204... The sliding installation of the clearance groove 303 opened in 301 allows the connecting pin 304 to drive the sealing top plate 2 301 to slide into the connecting groove 302 opened in the sealing top plate 1. At the same time, the connecting pin 304 will press the limiting slider 306 to both sides, causing the limiting slider 306 to drive the unlocking block 308 to slide along the clearance groove 307. Simultaneously, the limiting slider 306 will compress the limiting spring 309 inside the limiting groove 2 305. When the limiting slider 306 is disengaged from the surface of the connecting pin 304, the limiting spring 2 309 will push the limiting slider 306, causing the limiting slider 306 to engage in the groove of the connecting pin 304, thereby limiting the connecting pin 304 and limiting the sealing top plate 2 301, thus connecting them and enabling longer sealing operations.
