Utility model patent application CN200520011491.6 discloses a rapid diversion and leak-sealing device. This device involves welding a diversion sealing head onto a diversion sealing mechanism, sealing the rain valve within the mechanism. When using this sealing device for welding, the spraying of fire-extinguishing dry powder into the interlayer between the inner and outer short pipes prevents the contact between flammable gas and open flame during welding of the outer short pipe. The possibility of combustible gas explosion is eliminated, thus ensuring absolute safety during the welding process. A single modification to the existing plugging device completely solves the potential safety hazards in plugging and emergency repairs. Moreover, the structure is very simple, the operation is easy, and it is practical and economical. According to its publicly available technical solution, existing leak-stopping and diversion equipment often fails to divert water to the required location during diversion operations, hindering rapid diversion work. Furthermore, during leak-stopping operations, it often cannot perform the plugging work quickly, reducing work efficiency. Utility Model Content

[0003] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a leak-stopping and diversion device to solve the problems mentioned in the background art. This utility model can quickly divert water to the required location and facilitate rapid leak-stopping work.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a leak-stopping and drainage device, comprising an upper ring and an upper sleeve, a connecting assembly installed at the bottom of the upper sleeve, the connecting assembly comprising a lower ring and a lower sleeve, a discharge assembly installed on the upper sleeve, the discharge assembly comprising a connecting pipe and a valve, a drainage assembly installed on the connecting pipe, the drainage assembly comprising a flange and a water pump, a limiting assembly installed on the inner side of both the upper and lower rings, the limiting assembly comprising a support ring and an inner ring, a pushing assembly installed on the support ring, the pushing assembly comprising a lead screw and a retaining ring, and a sealing mechanism installed on both the upper and lower rings, the sealing mechanism comprising a spring.

[0005] Furthermore, the upper ring is integrally formed on both sides of the upper sleeve, and the lower ring is integrally formed on both sides of the lower sleeve. Connecting plates are welded to both sides of the upper ring, lower ring, upper sleeve, and lower sleeve. Fixing bolts are installed on the connecting plates. The upper ring and upper sleeve are fixed to the top of the lower ring and lower sleeve by the connecting plates and fixing bolts.

[0006] Furthermore, the connecting pipe is welded to the top of the upper sleeve, and the connecting pipe is connected to the inner side of the upper sleeve. One side of the valve is installed on the inner side of the connecting pipe, and the other side of the valve extends to the outer side of the connecting pipe.

[0007] Furthermore, the flange is welded to the top of the connecting pipe, the bottom of the water pump is mounted on the top of the flange via a bearing, the bottom of the water pump is secured to the top of the flange by a sealing ring, and an outlet pipe is welded to one side of the water pump.

[0008] Furthermore, the support rings are integrally formed on the inner walls of the upper ring and the lower ring, respectively. The support rings are welded to the outer side of one end of the inner ring. The inner rings are located inside the upper ring and the lower ring, respectively. The other end of the inner ring is locked to the outer side of the spring piece.

[0009] Furthermore, one end of the lead screw is mounted on the inner side of the support ring via a bearing, and the other end of the lead screw passes through the retaining ring via a thread and extends to the inner side of the lower or upper ring.

[0010] Furthermore, the outer side of the retaining ring is engaged with the inner wall of the upper or lower ring, the inner side of the retaining ring is fitted onto the outer side of the inner ring, and the outer side of the inner ring is coated with sealant.

[0011] Furthermore, the spring pieces are respectively welded to the inner wall of the upper ring or the lower ring, and the spring pieces are evenly distributed on the upper ring or the lower ring. The spring pieces are semi-circular spring pieces.

[0012] Beneficial effects:

[0013] 1. When using this leak-sealing and drainage device, turn on the water pump, align the upper ring and upper sleeve with the lower ring and lower sleeve on both sides of the pipe. The water pump will draw the leaking water out of the pipe through the connecting pipe, thereby reducing the pressure on the outside of the damaged pipe with the upper and lower sleeves. This facilitates the quick installation and fixing of the upper ring and upper sleeve with the lower ring and lower sleeve on the outside of the pipe. Depending on the location of the drainage ditch, pond, etc., the water pump can be rotated on the flange to quickly drain the water to the required location for drainage work. After the upper ring and upper sleeve with the lower ring and lower sleeve have completed the leak-sealing work, close the valve and remove the water pump through the bolts on the flange so that the water pump can be recycled and reused, reducing equipment waste.

[0014] 2. After the upper ring and upper sleeve are installed and fixed to the lower ring and lower sleeve via the fixing bolts on the connecting plate, the leak-stopping and drainage device is rotated to the screw rod. Under the support of the support ring, the screw rod pushes the retaining ring between the inner ring and the upper or lower ring towards the spring plate. The sealant located between the inner ring and the upper or lower ring is pushed through the gap between the spring plate and the pipe to the gap between the spring plate and the upper or lower ring. After the water pump stops working and the valve is closed, the water pressure between the upper sleeve and the lower sleeve pushes the spring plate, causing the spring plate to be squeezed and clamped on the outside of the pipe under water pressure. The sealant is used to seal the gap between the spring plate and the pipe, effectively preventing leakage between the upper and lower rings and the outside of the pipe, ensuring the sealing effect, and enabling rapid leak-stopping work, thus improving work efficiency.

[0015] 3. This leak-stopping and drainage device is reasonably designed, highly efficient and convenient to use, and suitable for leak-stopping and drainage of pipelines in water conservancy projects. Attached Figure Description

A pushing assembly is installed on the support ring 11. The pushing assembly includes a screw 13 and a retaining ring 14. Sealing mechanisms are installed on both the upper ring 1 and the lower ring 3. The sealing mechanism includes a spring 15. The connecting pipe 6 is welded to the top of the upper sleeve 2 and communicates with the inner side of the upper sleeve 2. One side of the valve 7 is installed on the inner side of the connecting pipe 6, and the other side of the valve 7 extends to the outer side of the connecting pipe 6. The flange 8 is welded to the connecting pipe 6. At the top, the bottom of the water pump 9 is mounted on the top of the flange 8 via a bearing. The bottom of the water pump 9 is secured to the top of the flange 8 via a sealing ring. An outlet pipe 10 is welded to one side of the water pump 9. In use, the water pump 9 is turned on, and the upper ring 1 and upper sleeve 2 are aligned with the lower ring 3 and lower sleeve 4 on both sides of the pipe. The water pump 9 draws out the leaking water from the pipe through the connecting pipe 6, thereby reducing the pressure on the upper sleeve 2 and lower sleeve 4 on the outside of the damaged pipe. This facilitates the quick installation and fixation of the upper ring 1 and upper sleeve 2 with the lower ring 3 and lower sleeve 4 on the outside of the pipe. Depending on the location of the water drainage ditch, pond, etc., the water pump 9 is rotated on the flange 8 to quickly divert the water to the required location for drainage work. After the upper ring 1 and upper sleeve 2 and lower ring 3 and lower sleeve 4 have completed the leak sealing work, the valve 7 is closed, and the water pump 9 is removed via bolts on the flange 8 so that the water pump 9 can be recycled and reused, reducing equipment waste.

[0022] In this embodiment, the upper ring 1 is integrally formed on both sides of the upper sleeve 2, and the lower ring 3 is integrally formed on both sides of the lower sleeve 4. Connecting plates 5 are welded to both sides of the upper ring 1, lower ring 3, upper sleeve 2, and lower sleeve 4. Fixing bolts are installed on the connecting plates 5. The upper ring 1 and upper sleeve 2 are fixed to the top of the lower ring 3 and lower sleeve 4 by the connecting plates 5 and the fixing bolts. Support rings 11 are integrally formed on the inner walls of the upper ring 1 and lower ring 3, respectively. The support rings 11 are welded to the outer side of one end of the inner ring 12. Ring 12 is located inside the upper ring 1 and the lower ring 3 respectively. The other end of the inner ring 12 is engaged with the outer side of the spring piece 15. One end of the lead screw 13 is mounted inside the support ring 11 via a bearing. The other end of the lead screw 13 passes through the retaining ring 14 via a thread and extends to the inner side of the lower ring 3 or the upper ring 1. The outer side of the retaining ring 14 is engaged with the inner wall of the upper ring 1 or the lower ring 3. The inner side of the retaining ring 14 is sleeved on the outer side of the inner ring 12. The outer side of the inner ring 12 is covered with sealant. 5 are welded to the inner wall of the upper ring 1 or the lower ring 3 respectively. The spring pieces 15 are evenly distributed on the upper ring 1 or the lower ring 3. The spring pieces 15 are semi-circular spring pieces. After the upper ring 1 and the upper sleeve 2 are installed and fixed to the lower ring 3 and the lower sleeve 4 through the fixing bolts on the connecting plate 5, the screw rod 13 is turned. Under the support of the support ring 11, the screw rod 13 pushes the retaining ring 14 between the inner ring 12 and the upper ring 1 or the lower ring 3 toward the spring piece 15, and pushes the sealant located between the inner ring 12 and the upper ring 1 or the lower ring 3 through the spring piece. The gap between the spring 15 and the pipe is pushed to the gap between the spring 15 and the upper ring 1 or the lower ring 3. After the water pump 9 stops working and the valve 7 is closed, the water pressure between the upper sleeve 2 and the lower sleeve 4 pushes the spring 15, so that the spring 15 is squeezed and clamped on the outside of the pipe under water pressure. The gap between the spring 15 and the pipe is sealed with sealant, which effectively prevents leakage between the upper ring 1 and the lower ring 3 and the outside of the pipe, ensuring the sealing effect. At the same time, it can quickly perform leak-stopping work and improve work efficiency.

[0023] This leak-sealing and drainage device provides power to all electrical equipment via an external power source. In use, the water pump 9 is turned on, and the upper ring 1 and upper sleeve 2 are aligned with the lower ring 3 and lower sleeve 4 on both sides of the pipe. The water pump 9, through the connecting pipe 6, draws the leaking water out of the pipe, thereby reducing the pressure on the outside of the damaged pipe via the upper sleeve 2 and lower sleeve 4. This facilitates the quick installation and fixation of the upper ring 1 and upper sleeve 2 with the lower ring 3 and lower sleeve 4 on the outside of the pipe. Depending on the location of the drainage ditch, pond, etc., the water pump 9 is rotated on the flange 8 to quickly divert the water to the required location. After the leak-sealing work is completed, the valve 7 is closed, and the water pump 9 is removed via bolts on the flange 8 so that it can be recycled and reused, reducing equipment waste. After the upper ring 1 and upper sleeve 2 are installed and fixed to the lower ring 3 and lower sleeve 4 through the fixing bolts on the connecting plate 5, the screw rod 13 is then turned. Under the support of the support ring 11, the screw rod 13 pushes the retaining ring 14 between the inner ring 12 and the upper ring 1 or lower ring 3 toward the spring piece 15. The sealant located between the inner ring 12 and the upper ring 1 or lower ring 3 is pushed through the gap between the spring piece 15 and the pipe to the gap between the spring piece 15 and the upper ring 1 or lower ring 3. After the water pump 9 stops working and the valve 7 is closed, the water pressure between the upper sleeve 2 and the lower sleeve 4 pushes the spring piece 15, so that the spring piece 15 is squeezed and clamped on the outside of the pipe under water pressure. The sealant is used to seal the gap between the spring piece 15 and the pipe, effectively preventing leakage between the upper ring 1 and the lower ring 3 and the outside of the pipe, ensuring the sealing effect, and enabling quick leak sealing work, thus improving work efficiency.
