[0002] Dams intercept water flow, store water and regulate water levels. Dams include gravity dams, earth-rock dams and arch dams. Earth-rock dams refer to dams that use a large amount of earth and stone materials to pile up as a water barrier and diversion project to achieve the purpose of regulating water levels, flood control and water storage. At present, the methods for preventing leakage in earth-rock dams are mostly through plugging and backfilling. However, when leakage occurs in existing earth-rock dams, excavators are usually used to dig up the leakage, compact it and backfill it. However, in this process, it is difficult for mechanical equipment to quickly reach the dam for seepage treatment. When leakage is found in the dam, geotextile bags filled with soil are usually manually stuffed into the leakage to seal it.

[0026] The present invention drives the second support frame, the ball shaft, the breaking rod and the tapered rod to be inserted into the earth-rock dam through the docking ring. Since the tapered rod is tapered, it is convenient to insert into the dam.

DETAILED DESCRIPTION

[0040] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0041] like Figures 1 to 10 As shown, the present invention provides a plugging device for water conservancy dam leakage, comprising a support plate 1, and also comprising:

[0042] A first stabilizing bar 7 is fixedly mounted on the bottom of the support plate 1;

[0043] A plugging component 3, the plugging component 3 is installed on the support plate 1;

[0044] A forward and reverse motor for driving the transmission component 4 to rotate is fixed on the top of the fixing component 2. The plugging component 3 moves back and forth under the drive of the transmission component 4 and is inserted into the leakage part of the dam.

[0045] An injection component 5, the injection component 5 is connected to the plugging component 3;

[0046] An adjusting component 6, which is arranged at one end of the blocking component 3;

[0047] The plugging assembly 3 includes a first support frame 34 movably sleeved in the support plate 1, a connecting pipe 33 is sleeved on the outer thread of the threaded rod 42 in the transmission assembly 4, a docking ring 32 is fixedly installed at the bottom of the connecting pipe 33, and a second support frame 36 is movably sleeved inside the docking ring 32;

[0048] The second support frame 36 has a circular hole on its surface, and a ball shaft 39 is sleeved inside the circular hole. The first support frame 34 has a hole corresponding to the circular hole on its surface, and a rubber ring 35 is arranged inside the hole.

[0049] The ball shaft 39 and the rubber ring 35 are provided with a breaker rod 31 in an inner movable sleeve, the ball shaft 39 is provided with a fixing plate 30 fixedly mounted on the outside, a docking plate 37 is fixedly mounted on one end of the breaker rod 31, and a return spring 38 is elastically connected between the docking plate 37 and the fixing plate 30;

[0050] The other end of the crushing rod 31 is movably sleeved with a tapered rod 312 .

[0051] By detecting the leakage of the earth-rock dam, the plugging component 3 is fixed on the slope of the earth-rock dam through the fixing component 2 and the first stabilizing rod 7, and the plugging component 3 is kept horizontal with the leakage. The motor drives the transmission component 4 to rotate and drive the plugging component 3 to move back and forth, and the docking ring 32 drives the second support frame 36, the ball shaft 39 and the return spring 38 to move, so that the breaking rod 31 and the tapered rod 312 are inserted into the earth-rock dam. Since the tapered rod 312 is tapered, it is convenient to insert into the dam. At the same time, multiple breaking rods 31 are inserted into the leakage of the earth-rock dam, and the soil around the leakage of the earth-rock dam is loosened, so that the soil around the leakage of the earth-rock dam expands, and the soil expands to fill the leakage, so as to achieve the effect of plugging the leakage of the earth-rock dam. After loosening and plugging the leakage, the leakage is backfilled and compacted to improve the effect of plugging the leakage.

[0052] In this specification, the length of the breaker rod 31 is designed according to actual use requirements. By increasing the length of the breaker rod 31, the effect of plugging the leakage of the earth-rock dam can be improved.

[0053] During the process of inserting the breaker rod 31 into the earth-rock dam, since the earth-rock dam is mixed with gravel, the conical rod 312 and the breaker rod 31 are inserted into the earth-rock dam, and the conical rod 312 is blocked by the gravel and cannot continue to move forward, while the conical rod 312 and the breaker rod 31 are continuously subjected to the forward force. Since one end of the conical rod 312 is in a cone shape and contacts the surface of the gravel, and most of the gravel is approximately round, the conical rod 312 slides along the surface of the gravel, so that the breaker rod 31 rotates with the ball shaft 39 as the central axis, and compresses the rubber ring 35, so that one end of the conical rod 312 is out of contact with the surface of the gravel, so that the conical rod 312 and the breaker rod 31 can enter the earth-rock dam normally;

[0054] When the volume of the gravel is too large or the surface is concave, the conical rod 312 and the breaking rod 31 are blocked and cannot move forward, while the second support frame 36 and the ball shaft 39 continue to move forward, and the breaking rod 31 stretches the reset spring 38 to ensure that the other breaking rods 31 and the conical rod 312 can enter the earth-rock dam normally.

[0055] like Figure 5 , Figure 8 and Fig. 9 As shown, the transmission assembly 4 includes a stabilizing frame 41 fixedly mounted on the side of the support plate 1, a threaded rod 42 is mounted on the side of the support plate 1, a first circular plate 45 is fixedly mounted on one end of the threaded rod 42, and a limiting frame 43 is fixedly mounted on one end of the stabilizing frame 41, and the limiting frame 43 is engaged with the side of the first circular plate 45 for supporting the threaded rod 42;

[0056] The connecting pipe 33 is threadedly sleeved on the outside of the threaded rod 42 .

[0057] The threaded rod 42 is driven to rotate by the motor, and the connecting tube 33 moves along the surface of the threaded rod 42. Since the first circular plate 45 is movably engaged with the side of the limiting frame 43, the other end of the threaded rod 42 is supported by the stabilizing frame 41 and the first circular plate 45 during the rotation of the threaded rod 42, thereby ensuring the stability of the rotation of the threaded rod 42.

[0058] like Figure 3-Figure 5 and Figure 8 As shown, the adjustment assembly 6 includes a stabilizing plate 66 fixed to the side of the second support frame 36, a guide rod 67 is fixed to the outside of the stabilizing plate 66, the side of the second support frame 36 is connected to the second circular plate 63 through a spring piece 61, and the inner wall of the second circular plate 63 is provided with a guide groove 65 for the guide rod 67 to slide.

[0059] The inner wall of the second circular plate 63 contacts the outer wall of the stabilizing plate 66 , and the second circular plate 63 slides transversely along the surfaces of the stabilizing plate 66 and the guide rod 67 .

[0060] The second circular plate 63 is provided with a second protrusion 62 in an annular array on the side thereof, and the first circular plate 45 is provided with a first protrusion 44 in an annular array on the side thereof. The second protrusion 62 is kept opposite to the first protrusion 44;

[0061] The docking ring 32 moves in the reverse direction to break away from the earth-rock dam, the second protrusion 62 engages with the first protrusion 44, and the first circular plate 45 and the first protrusion 44 drive the second circular plate 63, the docking ring 32 and the breaker rod 31 to rotate, changing the initial position of the breaker rod 31.

[0062] The threaded rod 42 is rotated to drive the breaker rod 31 and the tapered rod 312 to be inserted into the earth-rock dam. During this process, the second protrusion 62 is disengaged from the first protrusion 44, and the breaker rod 31 and the tapered rod 312 are completely inserted into the earth-rock dam. At this time, the driving motor drives the threaded rod 42 to rotate in the opposite direction, and the breaker rod 31 and the tapered rod 312 move in the opposite direction. During the movement, the second protrusion 62 is engaged with the first protrusion 44, and the second protrusion 62, the second circular plate 63, the stabilizing plate 66, the docking ring 32, the breaker rod 31 and the first supporting frame 34 are driven by the first protrusion 44 to rotate randomly. The position of the breaker rod 31 is changed during the rotation process, and then the breaker rod 31 and the tapered rod 312 are driven by the motor to be inserted into the earth-rock dam, and the position of the breaker rod 31 and the tapered rod 312 inserted into the dam is changed. By repeatedly squeezing the leakage around the earth-rock dam, it is ensured that the soil around the leakage is fully expanded so that the leakage is completely filled, thereby improving the effect of blocking leakage in the dam.

[0063] When the second protrusion 62 is engaged with the first protrusion 44, the docking ring 32 continues to move in the opposite direction, and the second circular plate 63 is blocked by the first protrusion 44 and cannot move. The second circular plate 63 moves along the guide rod 67 and the stabilizing plate 66 and compresses the spring piece 61, ensuring that the second protrusion 62 and the first protrusion 44 are always in an engaged state, and driving the docking ring 32 to rotate.

[0064] like Figure 5-Figure 7 As shown, the interior of the conical rod 312 is a hollow structure, the conical rod 312 is connected to the crushing rod 31, and a through groove 311 is formed on the outside of the conical rod 312;

[0065] The injection assembly 5 includes a butt joint pipe 52 connected to one end of the crushing rod 31 , one end of the butt joint pipe 52 is connected to a diverter ring 53 , and the top of the diverter ring 53 is connected to the injection pipe 51 .

[0066] The leakage of the earth-rock dam is detected. For leakage caused by termites or animal holes, the conical rod 312 and the breaking rod 31 are inserted into the leakage of the earth-rock dam to break the soil around the leakage, so that the soil expands and fills the leakage of the dam to seal it. The injection pipe 51 is docked with the injection equipment, and the medicine is injected into the breaking rod 31 and the conical rod 312 through the injection pipe 51, the diverter ring 53 and the docking pipe 52. When the breaking rod 31 and the conical rod 312 move in the opposite direction to leave the earth-rock dam, the conical rod 312 is gradually pulled out of the breaking rod 31 by the friction of the soil, and the medicine in the breaking rod 31 and the conical rod 312 is discharged into the earth-rock dam through the through groove 311, so as to kill the termites or other animals in the leakage of the earth-rock dam and avoid the situation that the leakage continues to occur after the sealing of the leakage is completed. At the same time, the present solution can also inject the filling slurry into the leakage place through the injection assembly 5, the breaking rod 31 and the conical rod 312.

[0067] like Figure 1 , Figure 2 and Fig.10 As shown, the fixing assembly 2 includes a fixing frame 21 fixedly mounted on the other side of the supporting plate 1, a movable rod 22 is movably sleeved inside the fixing frame 21, a connecting plate 23 is fixedly mounted on one end of the movable rod 22, and a second stabilizing rod 24 is fixedly mounted on the bottom of the connecting plate 23;

[0068] The fixing frame 21 is provided with a rectangular through slot, in which a limit rod 26 is fixed, and a nut 25 is provided on the outer thread sleeve of the limit rod 26;

[0069] The movable rod 22 is sleeved on the outside of the limiting rod 26. The limiting rod 26 is conical and has a notch at one end.

[0070] According to the slope of the earth-rock dam, the nut 25 is rotated in the opposite direction to loosen the limit rod 26, so that the movable rod 22 can be lengthened, and the length of the movable rod 22 and the fixing frame 21 can be increased. The nut 25 is then rotated to squeeze the limit rod 26 to fix the length of the movable rod 22. It can be adjusted according to the slope of different dams. The first stabilizing rod 7 and the second stabilizing rod 24 can be inserted into the slope of the dam to fix the plugging assembly 3.

[0071] The working principle and use process of the present invention:

[0072] By detecting the leakage of the earth-rock dam, the plugging component 3 is fixed on the slope of the earth-rock dam through the fixing component 2 and the first stabilizing rod 7, and the plugging component 3 is kept horizontal with the leakage. The motor drives the transmission component 4 to rotate and drive the plugging component 3 to move back and forth, and the docking ring 32 drives the second support frame 36, the ball shaft 39 and the return spring 38 to move, so that the breaking rod 31 and the tapered rod 312 are inserted into the earth-rock dam. Since the tapered rod 312 is tapered, it is convenient to insert into the dam. At the same time, multiple breaking rods 31 are inserted into the leakage of the earth-rock dam, and the soil around the leakage of the earth-rock dam is loosened, so that the soil around the leakage of the earth-rock dam expands, and the soil expands to fill the leakage, so as to achieve the effect of plugging the leakage of the earth-rock dam. After loosening and plugging the leakage, the leakage is backfilled and compacted to improve the effect of plugging the leakage.

[0073] During the process of inserting the breaker rod 31 into the earth-rock dam, since the earth-rock dam is mixed with gravel, the conical rod 312 and the breaker rod 31 are inserted into the earth-rock dam, and the conical rod 312 is blocked by the gravel and cannot continue to move forward, while the conical rod 312 and the breaker rod 31 are continuously subjected to the forward force. Since one end of the conical rod 312 is in a cone shape and contacts the surface of the gravel, and most of the gravel is approximately round, the conical rod 312 slides along the surface of the gravel, so that the breaker rod 31 rotates with the ball shaft 39 as the central axis, and compresses the rubber ring 35, so that one end of the conical rod 312 is out of contact with the surface of the gravel, so that the conical rod 312 and the breaker rod 31 can enter the earth-rock dam normally;

[0074] When the volume of the crushed stone is too large or the surface is concave, the conical rod 312 and the breaker rod 31 are blocked and cannot move forward, while the second support frame 36 and the ball shaft 39 continue to move forward, and the breaker rod 31 stretches the return spring 38 to ensure that the other breaker rods 31 and the conical rod 312 can enter the earth-rock dam normally;

[0075] The threaded rod 42 is rotated to drive the breaker rod 31 and the tapered rod 312 to be inserted into the earth-rock dam. During this process, the second protrusion 62 is disengaged from the first protrusion 44, and the breaker rod 31 and the tapered rod 312 are completely inserted into the earth-rock dam. At this time, the driving motor drives the threaded rod 42 to rotate in the opposite direction, and the breaker rod 31 and the tapered rod 312 move in the opposite direction. During the movement, the second protrusion 62 is engaged with the first protrusion 44, and the second protrusion 62, the second circular plate 63, the stabilizing plate 66, the docking ring 32, the breaker rod 31 and the first supporting frame 34 are driven by the first protrusion 44 to rotate randomly. The position of the breaker rod 31 is changed during the rotation process, and then the breaker rod 31 and the tapered rod 312 are driven by the motor to be inserted into the earth-rock dam, and the position of the breaker rod 31 and the tapered rod 312 inserted into the dam is changed. By repeatedly squeezing the leakage around the earth-rock dam, it is ensured that the soil around the leakage is fully expanded so that the leakage is completely filled, thereby improving the effect of blocking leakage in the dam.

[0076] When the second protrusion 62 is engaged with the first protrusion 44, the docking ring 32 continues to move in the opposite direction, and the second circular plate 63 is blocked by the first protrusion 44 and cannot move. The second circular plate 63 moves along the guide rod 67 and the stabilizing plate 66 and compresses the spring sheet 61, ensuring that the second protrusion 62 is always in an engaged state with the first protrusion 44, and driving the docking ring 32 to rotate;

[0077] The leakage of the earth-rock dam is detected. For leakage caused by termites or animal holes, the conical rod 312 and the breaking rod 31 are inserted into the leakage of the earth-rock dam to break the soil around the leakage, so that the soil expands and fills the leakage of the dam to seal it. The injection pipe 51 is docked with the injection equipment, and the medicine is injected into the breaking rod 31 and the conical rod 312 through the injection pipe 51, the diverter ring 53 and the docking pipe 52. When the breaking rod 31 and the conical rod 312 move in the opposite direction to leave the earth-rock dam, the conical rod 312 is gradually pulled out of the breaking rod 31 by the friction of the soil, and the medicine in the breaking rod 31 and the conical rod 312 is discharged into the earth-rock dam through the through groove 311, so as to kill the termites or other animals in the leakage of the earth-rock dam and avoid the situation that the leakage continues to occur after the sealing of the leakage is completed. At the same time, the present solution can also inject the filling slurry into the leakage place through the injection assembly 5, the breaking rod 31 and the conical rod 312.
