[0023] 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.

[0024] Please see Figures 1-4 In this embodiment of the utility model, a rapid sealing device for pipeline leakage in water conservancy projects includes a sealing cover 1, and further includes:

[0025] Sealing gasket 12 is disposed inside the sealing cover 1, and one side of the sealing gasket 12 is adhered to the notch 26 of the tube body 25 by sealant.

[0026] The locking assembly secures the sealing cover 1 to the outer circumferential wall of the tube body 25;

[0027] The reinforcement component is located on one side of the locking component and is used to improve the fixing strength of the locking component.

[0028] The glue injection component is located on one side of the sealing cover 1. The entire sealing process does not require water interruption. At the same time, the sealing device is easy to operate and can quickly seal the leakage outside the pipe body 25, reducing water waste and project losses. In this sealing device, the triple seal of the sealing cover 1, the sealing gasket 12 and the sealing material (curing resin) effectively prevents leakage and avoids secondary leakage of the pipe body 25 after sealing.

[0029] Preferably, the locking assembly includes an extension plate 13 fixed to the outer circumferential wall of the sealing cover 1. A circular hole is provided on one side of the extension plate 13, and a threaded rod 14 is inserted into the inside of the circular hole. Both ends of the threaded rod 14 are threaded with fixing nuts 15. The operator passes multiple threaded rods 14 through the extension plate 13 and fixes them through the fixing nuts 15, so that the two sealing covers 1 are tightly fixed to the outer wall of the tube body 25, thereby achieving a one-time seal of the tube body 25.

[0030] Preferably, the glue injection assembly includes a positioning frame 19 fixed to the outer circumference of the sealing cover 1. A storage cylinder 2 is fixed to the inner circumference of the positioning frame 19. The storage cylinder 2 contains curing resin. An arc-shaped tube 27 is inserted into one end of the storage cylinder 2, and the other end of the arc-shaped tube 27 is connected to the sealing cover 1. A housing 3 is fixed to the outer circumference of the positioning frame 19. A second threaded screw 28 is rotatably connected to one side of the inner wall of the housing 3. A second threaded sleeve 31 engages with the outer circumference of the second threaded screw 28. A connecting plate 8 is fixed to one side of the outer wall of the second threaded sleeve 31, and a push-pull rod 7 is fixed to one side of the connecting plate 8. A piston 32 is fixed at the end of the push-pull rod 7 away from the connecting plate 8. The piston 32 is located inside the storage cylinder 2. After the sealing cover 1 is tightened, the operator rotates the second threaded screw 28. The rotation of the second threaded screw 28 can cause the second threaded sleeve 31, which is threaded to its outer wall, to drive the connecting plate 8 and the push-pull rod 7 to move horizontally. When the push-pull rod 7 moves horizontally, it can drive the piston 32 to squeeze out the cured resin in the storage cylinder 2. The squeezed-out cured resin flows into the sealing cover 1 through the arc-shaped tube 27, filling the gaps in the sealing cover 1 and achieving a triple seal at the leakage point of the pipe body 25.

[0031] Preferably, a first limiting groove 9 is provided on one side of the outer wall of the housing 3, and one end of the connecting plate 8 passes through the inside of the first limiting groove 9, ensuring that the connecting plate 8 can stably drive the push-pull rod 7 to move horizontally.

[0032] Preferably, an overflow pipe 24 is inserted into the outer circumference of the sealing cover 1 to ensure that the cured resin can fill the sealing cover 1.

[0033] Preferably, the reinforcement assembly includes a fixing frame 18 fixed to one side of the extension plate 13, the fixing frame 18 being fixedly connected to the positioning frame 19, a third helical gear 29 being fixed to one end of the second threaded screw 28, the third helical gear 29 meshing with a fourth helical gear 30, a first rotating column 4 being fixed to one side of the fourth helical gear 30, and two sets of both the fourth helical gear 30 and the first rotating column 4, a first helical gear 5 being fixed to the end of the first rotating column 4 away from the fourth helical gear 30, the first helical gear 5 meshing with a second helical gear 6, the rotation of the second threaded screw 28 can drive the third helical gear 29 to rotate, the rotation of the third helical gear 29 can drive the fourth helical gear 30 to rotate together, the rotation of the fourth helical gear 30 can drive the first rotating column 4 to rotate, and the rotation of the first rotating column 4 can drive the first helical gear 5 to rotate.

[0034] Preferably, a first threaded screw 23 is fixed to one side of the second helical gear 6. A first threaded sleeve 22 is threadedly connected to the outer circumference of the first threaded screw 23. A vertical column is fixed to the top outer wall of the first threaded sleeve 22. A second limiting groove 20 is provided on the top outer wall of the fixing frame 18. A slider 21 is fixed to the top of the vertical column. Horizontal plates are fixed to both outer walls of the first threaded sleeve 22. A fixing ring plate 17 is fixed to one end of the horizontal plate. A spring 11 is fixed to one outer wall of the fixing ring plate 17. A clamping ring plate 16 is fixed to the other end of the spring 11. One side of the ring plate 16 is pressed against the outer wall of one side of the fixing nut 15. Both the fixing ring plate 17 and the pressing ring plate 16 pass through one end of the threaded rod 14. The first helical gear 5 and the second helical gear 6 mesh with each other, thereby driving the first threaded screw 23 to rotate. When the first threaded screw 23 rotates, the first threaded sleeve 22, which is threaded to its outer wall, can move horizontally, thereby pressing the pressing ring plate 16 against the outer wall of one end of the fixing nut 15, thus strengthening the locking assembly and further improving the stability of the entire sealing device after sealing.

[0035] Working principle: When it is necessary to seal the gap 26 of the pipe body 25, the two sealing covers 1 can be first pressed tightly against the leakage point of the pipe body 25. Then, multiple threaded rods 14 are passed through the extension plate 13 and fixed by the fixing nut 15, so that the two sealing covers 1 are tightly fixed to the outer wall of the pipe body 25, achieving a primary seal for the pipe body 25. At the same time, the sealing gasket 12 on one side of the sealing cover 1 can be tightly adhered to the leakage point by the sealant, achieving a secondary seal for the pipe body 25. After the sealing cover 1 is tightened and fixed, the operator rotates the second threaded screw 28. The rotation of the second threaded screw 28 can cause the second threaded sleeve 31, which is threaded to its outer wall, to drive the connecting plate 8 and the push-pull rod 7 to move horizontally. When the push-pull rod 7 moves horizontally, it can drive the piston 32 to extrude the cured resin in the storage cylinder 2. The extruded cured resin passes through an arc The tube 27 flows into the sealing cover 1, filling the gaps inside the sealing cover 1, thus achieving a triple seal at the leakage point of the tube body 25. During the rotation of the second threaded screw 28, it can drive the third helical gear 29 to rotate. When the third helical gear 29 rotates, it can drive the fourth helical gear 30 to rotate together. The rotation of the fourth helical gear 30 can drive the first rotating column 4 to rotate. During the rotation of the first rotating column 4, it can drive the first helical gear 5 to rotate. At this time, the first helical gear 5 and the second helical gear 6 mesh with each other, thereby driving the first threaded screw 23 to rotate. When the first threaded screw 23 rotates, it can cause the first threaded sleeve 22, which is threaded to its outer wall, to move horizontally, thereby pressing the clamping ring plate 16 against the outer wall of one end of the fixing nut 15, thus strengthening the locking assembly and further improving the stability of the entire sealing device after sealing.

[0036] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention.
