Description

Technical Field

[0001] This utility model relates to the field of anti-seepage devices, specifically an anti-seepage device for water supply and drainage pipes in building engineering. Background Technology

[0002] Existing waterproofing devices for water supply and drainage pipes in building construction commonly use adhesive waterproof tape to seal the joints between two pipes. This simple method can indeed prevent water leakage at the pipe joints to a certain extent initially. However, over time, the waterproof tape inevitably faces the problems of aging and material degradation. Prolonged exposure to humid environments or external friction will gradually weaken the tape's adhesiveness until it eventually loses its adhesion, making it prone to detachment.

[0003] A search revealed a publication number (CN222142298U) that discloses a seepage prevention device for water supply and drainage pipes in building engineering, comprising a fixing device, a seepage prevention device, and a water pipe. The fixing device includes an annular component, a fixing component, and a rotating knob, wherein the fixing component is movably mounted on the annular component; the rotating knob is connected to the fixing component; the seepage prevention device includes a seepage prevention component, wherein the seepage prevention component is disposed on the inner wall of the annular component; and the water pipe is disposed within the seepage prevention component.

[0004] The technical solution has at least the following drawbacks: although it can connect and seal two drainage pipes, it cannot perform a secondary seal on the drainage pipes during the sealing process, thus failing to reduce the possibility of water leakage. Therefore, we propose a seepage prevention device for water supply and drainage pipes in building engineering. Utility Model Content

[0005] The purpose of this utility model is to provide a seepage prevention device for water supply and drainage pipes in building engineering, which solves the problem mentioned in the background technology that the drainage pipe cannot be sealed again during the sealing process, thereby reducing the occurrence of water seepage in the drainage pipe.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a seepage prevention device for water supply and drainage pipes in building engineering, comprising a seepage prevention cylinder, with drainage pipe bodies provided on both sides of the inner cavity of the seepage prevention cylinder, a first rubber ring bonded to the middle of the inner cavity of the seepage prevention cylinder, a second rubber ring bonded to the inner side of the first rubber ring, through grooves opened on both sides of the upper end of the seepage prevention cylinder, a limiting frame provided at the upper end of the seepage prevention cylinder, a lead screw rotatably mounted on the middle of the upper end of the seepage prevention cylinder via a bearing, annular airbags bonded to both sides of the inner cavity of the seepage prevention cylinder, an air storage bag bonded to the upper end of the seepage prevention cylinder, and the air storage bag being positioned below the limiting frame.

[0007] By adopting the above technical solution, the lead screw and lead screw sleeve can drive the limiting frame to move downwards. The limiting frame passes through the through groove and abuts against the upper surface of the two drainage pipe bodies. With the support block, the drainage pipe bodies are installed and confined inside the anti-seepage cylinder, thus achieving a preliminary anti-seepage connection of the drainage pipes. At the same time, during the downward movement of the limiting frame, the limiting frame will press the air storage bag, causing the air inside the air storage bag to be discharged into the annular air bag through the hose. The annular air bag inflates and expands, fitting tightly against the surface of the drainage pipe body, thus forming a secondary seal on both sides of the first rubber ring. This achieves the effect of secondary sealing during the installation of the drainage pipe, thereby reducing the possibility of water leakage from the drainage pipe.

[0008] Optionally, multiple ball bearings are rolled on the inner walls of both ends of the seepage-proof cylinder, and the ball bearings are arranged in a ring.

[0009] By adopting the above technical solution and by setting the ball bearings, the main body of the drainage pipe inserted into the seepage-proof cylinder can be guided and limited, thereby facilitating the main body of the drainage pipe to pass through the annular airbag and connect to the first rubber ring.

[0010] Optionally, a lead screw sleeve is fixedly installed in the middle of the limiting frame, and the lead screw is threadedly connected to the lead screw sleeve.

[0011] By adopting the above technical solution, the limit frame can be moved through the cooperation of the lead screw and lead screw sleeve.

[0012] Optionally, the dimensions of both ends of the limiting frame are adapted to the dimensions of the through groove, and the two ends of the limiting frame are movably connected to the through groove.

[0013] By adopting the above technical solution and setting the through groove, it is convenient to insert the limiting frame into the seepage-proof cylinder to press and limit the main body of the drainage pipe.

[0014] Optionally, support blocks are fixedly installed on both sides of the lower end of the inner cavity of the seepage-proof cylinder, and the support blocks are arranged symmetrically.

[0015] By adopting the above technical solution and setting up support blocks, it is convenient to support and limit the main body of the drainage pipe.

[0016] Optionally, the air outlet of the air reservoir is connected to a flexible hose, and the other end of the flexible hose is connected to the air inlet of the annular air bladder.

[0017] By adopting the above technical solution and using the hose, the air inside the air reservoir can be guided.

[0018] Compared with the prior art, the beneficial effects of the technical solution of this application are as follows:

[0019] The technical solution of this application, through the design of a seepage-proof cylinder, a drainage pipe body, a second rubber ring, a limiting frame, an air storage bladder, and a hose, allows the lead screw and lead screw sleeve to drive the limiting frame downwards. The limiting frame passes through the through groove and abuts against the upper surfaces of the two drainage pipe bodies. With the assistance of the support block, the drainage pipe body is installed and confined within the seepage-proof cylinder, thus achieving a preliminary seepage-proof connection of the drainage pipe. Simultaneously, during the downward movement of the limiting frame, it presses against the air storage bladder, causing the air inside the bladder to be discharged into the annular air bladder through the hose. The annular air bladder inflates and presses tightly against the surface of the drainage pipe body, thus forming a secondary seal on both sides of the first rubber ring. This achieves a secondary sealing effect during the installation of the drainage pipe, thereby reducing the possibility of water leakage. Attached Figure Description

Drainage pipe bodies 11 are provided on both sides of the inner cavity of the seepage prevention cylinder 1. A first rubber ring 12 is bonded to the middle of the inner cavity of the seepage prevention cylinder 1, and a second rubber ring 13 is bonded to the inner side of the first rubber ring 12. Through grooves 14 are provided on both sides of the upper end of the seepage prevention cylinder 1. A limit frame 2 is provided at the upper end of the seepage prevention cylinder 1. A lead screw 21 is rotatably mounted on the middle of the upper end of the seepage prevention cylinder 1 via a bearing. Annular airbags 4 are bonded to both sides of the inner cavity of the seepage prevention cylinder 1, and an air storage bag 3 is bonded to the upper end of the seepage prevention cylinder 1, with the air storage bag 3 positioned below the limit frame 2. The dimensions of both ends of the limiting frame 2 are adapted to the dimensions of the through groove 14, and the two ends of the limiting frame 2 are movably connected to the through groove 14. Through the setting of the through groove 14, it is convenient for the limiting frame 2 to be inserted into the seepage prevention cylinder 1 to press and limit the main body 11 of the drainage pipe. Support blocks 23 are fixedly installed on both sides of the lower end of the inner cavity of the seepage prevention cylinder 1. The support blocks 23 are symmetrically arranged. Through the setting of the support blocks 23, it is convenient to support and limit the main body 11 of the drainage pipe. The air outlet of the air storage bag 3 is connected to the hose 5. The other end of the hose 5 is connected to the air inlet of the annular air bag 4. Through the setting of the hose 5, the air in the air storage bag 3 can be guided.

[0026] Multiple ball bearings 15 are rolled on the inner walls of both ends of the seepage-proof cylinder 1, and the ball bearings 15 are arranged in a ring. The ball bearings 15 can guide and limit the drainage pipe body 11 inserted into the seepage-proof cylinder 1, so that the drainage pipe body 11 can pass through the annular airbag 4 and connect to the first rubber ring 12.

[0027] A screw rod 21 is fixedly installed in the middle of the limiting frame 2. The screw rod 21 is threadedly connected to the screw rod 21, and the limiting frame 2 can be moved by the cooperation between the screw rod 21 and the screw rod 21.

[0028] During connection, firstly, insert the two drain pipe bodies 11 into both sides of the seepage-proof cylinder 1, so that the two drain pipe bodies 11 are inserted into the inner wall of the first rubber ring 12 and abut against the surface of the second rubber ring 13. Then rotate the screw 21, and the screw 21 sleeve drives the limiting frame 2 to move downward. The limiting frame 2 passes through the through groove 14 and abuts against the upper surface of the two drain pipe bodies 11. With the support block 23, the drain pipe bodies 11 are installed and limited inside the seepage-proof cylinder 1, thus achieving the initial seepage-proof connection of the drain pipe. At the same time, during the downward movement of the limiting frame 2, the limiting frame 2 will press the air storage bag 3, so that the air in the air storage bag 3 is discharged into the annular air bag 4 through the hose 5. The annular air bag 4 inflates and expands, and fits tightly against the surface of the drain pipe body 11, thus forming a secondary seal on both sides of the first rubber ring 12. This achieves the effect of secondary sealing in conjunction with the installation of the drain pipe, thereby reducing the possibility of water leakage from the drain pipe.
