Description

Technical Field

[0001] The invention relates to the technical field of water conservancy engineering, and in particular to a dam piping plugging device and a plugging method. Background Art

[0002] When the flood season comes, river embankments face severe tests. Piping is one of the common hazards of dams and dikes. Piping refers to the phenomenon that under the action of seepage, small particles in non-cohesive soil of the embankment pass through the pores of coarse particles and are moved or carried out by water flow. It is one of the forms of infiltration erosion and damage. Therefore, timely detection of piping and sealing of piping mouths as soon as possible are one of the key contents of embankment flood prevention and rescue.

[0003] In the prior art, a Chinese patent with publication number "CN114941309A" discloses a dam pipe burst plugging device and a method of using the same. By setting a filter cartridge with anti-filter material inside the filter cartridge, a blocking effect can be achieved, and the carried silt can be retained in the pipe body, which can effectively reduce the outflow of silt in the pipe burst channel, thereby achieving the effect of plugging the pipe burst, and can effectively prevent the expansion of the pipe burst outlet so that the staff can carry out subsequent processing. The existing plugging method uses sand and gravel, bagged soil, and most of the plugging materials used to plug the pipe burst are washed away with the burst channel, thereby wasting a lot of manpower and material resources, delaying the plugging time, and causing safety hazards.

[0004] In the pipe burst plugging work, it is necessary to first use a plugging device to plug the water outlet, and then find the water outlet point on one side of the dam body in the water area for emergency rescue and plugging. As described above, the flow of water is used to drive the blades to rotate, driving the central axis to rotate and causing the cleaning rod and the spiral blade to rotate. The cleaning rod can prevent the mud and sand from clogging the bottom of the filter cartridge. However, in this process, the spiral blade is always in a state of spiral pushing the mud and sand in the pipe. When the spiral blade keeps pushing the mud and sand in the pipe body, the mud and sand will be in a state of mixing with the pipe burst water, and the mud and sand will be in a flowing state. This may cause more mud and sand to flow and fine mud and sand to be discharged, reducing the plugging effect of the pipe body. Therefore, the present invention proposes a dam pipe burst plugging device and a plugging method to solve the above-mentioned problems. Summary of the invention

In the present invention, the sealing block blocking the water hole is conveniently lowered by rotating the adjusting screw rod, so that the water hole can flow water normally. When the pipe water passes through the turbine blades, the turbine blades will drive the cleaning plate on the L-shaped plate to rotate. The cleaning plate in the rotating state will clean the silt and impurities on the filter plate, effectively preventing the silt and impurities in the pipe water from clogging the filter plate, thereby ensuring the normal circulation and filtration of the pipe water; 2. In the present invention, when the cleaning plate rotates around the adjusting screw, the gear on the driving rod meshes with the gear block on the inner wall of the pipe body, so that the driving rod rotates on the cleaning plate through the bearing, and the stirring blade on the driving rod is used to stir and mix the pipe water near the filter plate, thereby preventing the filter plate from being blocked by sediment and impurities; 3. In the present invention, when the adjusting screw is rotated and descended, the positioning block is used to synchronously drive the driving block to descend. When the driving block descends, it presses down the rotating plate on the mounting plate through the rotating rod to open the discharge port in a closed state, so as to facilitate the discharge of pipe water from the pipe body. At the same time, the rotating plate on the mounting plate is used to improve the sealing of the pipe body. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] Example 2: Please refer to Figure 1-12 On the basis of the first embodiment, a stirring assembly is provided on the cleaning assembly, and the stirring assembly includes a bearing 22 and a tooth block 23.

[0026] In this embodiment, when the adjusting screw 9 rotates and descends, the positioning block 27 is used to synchronously drive the driving block 28 to descend. When the driving block 28 descends, it will press down the rotating plate 12 on the mounting plate 8 through the rotating rod 31, and open the discharge port 11 in a closed state, so as to facilitate the discharge of pipe water from the pipe body 1. At the same time, the rotating plate 12 on the mounting plate 8 is used to improve the sealing of the pipe body 1.

[0027] A dam piping blocking method, based on the dam piping blocking device described above, comprises the following steps: S1. When a piping point is found, the pipe body 1 is placed at the piping outlet, and then the pipe body 1 is fixed in position by using the existing positioning pins through the positioning holes 35 on the positioning plate 34; S2. After the pipe gushing water enters the pipe body 1 through the water inlet of the pipe body 1, the adjusting screw 9 is rotated by the adjusting block 33, and the adjusting screw 9 moves downward, and the sealing block 10 on the adjusting screw 9 moves away from the water through hole 6, and the pipe gushing water in the pipe body 1 enters the middle part of the pipe body 1 through the filter plate 7 and the water through hole 6; S3. When the adjusting screw 9 moves downward, the rotating plate 12 on the mounting plate 8 is pressed downward by the rotating rod 31 in the adjusting assembly to rotate, and the discharge port 11 on the mounting plate 8 is exposed. The pipe gushing water entering the middle part of the pipe body 1 is discharged through the discharge port 11. At the same time, when the pipe gushing water flows upward in the pipe body 1, the flow of water will drive the turbine blades 16 on the rotating block 13 to rotate. The turbine blades 16 will drive the cleaning plate 21 in the cleaning assembly to clean the filter plate 7 to prevent the silt and impurities in the pipe gushing water from clogging the filter plate 7. When the cleaning plate 21 rotates, the driving rod 24 on the cleaning plate 21 will drive the stirring blade 25 to rotate through the gear 26 and the tooth block 23. The pipe gushing water in the pipe body 1 is in a mixed state through the rotating stirring blade 25 to prevent excessive silt and impurities from adhering to the filter plate 7. S4. When it is not necessary to discharge the pipe gushing water, there is no need to rotate the adjusting screw 9. The water through hole 6 can be blocked by the sealing block 10 to prevent the pipe gushing water from flowing out of the pipe body 1.

[0028] Working principle: When in use, after the piping point is found, the pipe body 1 is placed at the piping outlet, and then the pipe body 1 is fixed in position by using the existing positioning pin through the positioning hole 35 on the positioning plate 34; After the pipe gushing water enters the pipe body 1 through the water inlet of the pipe body 1, the adjusting screw 9 is rotated by the adjusting block 33, and the adjusting screw 9 is connected with the mounting plate 8 by a thread, so that the adjusting screw 9 moves downward, and the sealing block 10 on the adjusting screw 9 moves away from the water through hole 6. At this time, the water through hole 6 can pass water normally, and the pipe gushing water in the pipe body 1 will enter the middle part of the pipe body 1 through the filter plate 7 and the water through hole 6; When the adjusting screw 9 moves downward, the driving block 28 installed on the adjusting screw 9 is rotated by the positioning block 27 to follow the adjusting screw 9 down. The driving block 28 in the descending state presses down the rotating plate 12 on the mounting plate 8 through the rotating rod 31 on the positioning rod 30, and the rotating plate 12 rotates at the position of the discharge port 11. As the rotating plate 12 rotates, the discharge port 11 on the mounting plate 8 is exposed, and the pipe water entering the middle part of the pipe body 1 is discharged through the discharge port 11. When the pipe gushing water flows upward in the pipe body 1, the flow of water will drive the turbine blades 16 on the rotating block 13 to rotate, and the turbine blades 16 will drive the connecting ring 36 on the rotating block 13 to rotate when rotating, and the connecting ring 36 will drive the rotating ring 18 to rotate through the L-shaped plate 17, and the rotating ring 18 will drive the sealing ring 20 to rotate through the connecting plate 19 when rotating, and the cleaning plate 21 on the sealing ring 20 will clean the filter plate 7 to prevent the silt and impurities in the pipe gushing water from clogging the filter plate 7; When the cleaning plate 21 rotates around the adjusting screw 9, the gear 26 on the driving rod 24 meshes with the tooth block 23 on the inner wall of the tube body 1, so that the driving rod 24 rotates on the cleaning plate 21 through the bearing 22, and the mixing blade 25 on the driving rod 24 mixes the pipe water near the filter plate 7, thereby preventing the filter plate 7 from being blocked by sediment and impurities. When it is not necessary to discharge the pipe water, there is no need to rotate the adjusting screw 9. The water hole 6 can be blocked by the sealing block 10 to prevent the pipe water from flowing out of the pipe body 1. At the same time, the rotating plate 12 on the mounting plate 8 is in a state of sealing the discharge port 11. Personnel can add sealing material on the mounting plate 8 and use the sealing material to improve the sealing performance of the pipe body 1. When water needs to pass through the pipe body 1, the sealing material can be taken out, and the rotating plate 12 on the mounting plate 8 can be rotated by rotating the adjusting screw 9 to expose the discharge port 11.

At the same time, when the pipe water flows upward in the pipe body (1), the flow of water drives the turbine blades (16) on the rotating block (13) to rotate, and the turbine blades (16) are The cleaning plate (21) in the cleaning assembly is driven to clean the filter plate (7) to prevent the silt and impurities in the pipe water from clogging the filter plate (7); and when the cleaning plate (21) rotates, the driving rod (24) on the cleaning plate (21) drives the stirring blade (25) to rotate via the gear (26) and the tooth block (23), so that the pipe water in the pipe body (1) is in a mixed state through the rotating stirring blade (25), thereby preventing excessive silt and impurities from adhering to the filter plate (7); S4. When it is not necessary to discharge the pipe gushing water, there is no need to rotate the adjusting screw (9), and the water through hole (6) can be blocked by the sealing block (10) to prevent the pipe gushing water from flowing out of the pipe body (1).
