Description

An emergency device for water supply pipe rupture Technical Field

[0001] This utility model relates to the field of water supply pipelines, specifically an emergency device for water supply pipeline rupture. Background Technology

[0002] A water supply pipeline is a piping system used to transport water. It is usually made of different materials, such as plastic, cast iron, steel, or cement. A water supply pipeline typically consists of multiple parts, including the water source, water treatment system, delivery pipeline, water tank, pumping station, and user end. In some chemical production processes, water supply pipelines usually transport industrial water, which may contain various chemicals and produce acidic or alkaline wastewater. If this wastewater is discharged directly into the drainage pipeline without treatment, it may react chemically with the water supply pipeline, causing corrosion and cracking, requiring repair of the damaged parts of the pipeline.

[0003] When repairing a ruptured water supply pipe, connecting fittings such as quick couplings and unions are often used to connect the ruptured pipe to a new pipe or fitting to achieve repair. With sufficient preparation, the installation of connecting fittings can be completed in about half an hour. If the pipe diameter is large or the connection is difficult, it may take longer and is quite time-consuming and labor-intensive. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this utility model provides an emergency device for water supply pipe rupture. Simply wrap the clamping mechanism around the ruptured part of the pipe and tighten the locking part to seal the rupture with a sealing gasket. This is convenient, quick, time-saving, labor-saving, and provides a good sealing effect.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: an emergency device for water supply pipe rupture, comprising a clamping mechanism and a sealing gasket. The clamping mechanism includes a fitting part for fitting the water supply pipe and a locking part for fixing. The fitting part has a chain structure, and the locking part is movably installed at the opening of the fitting part. The sealing gasket has a double-folded edge structure, and the folded edge is fixed to the clamping mechanism. Two clamping strips and two airbags are installed inside the sealing gasket. A rectangular structure for squeezing the sealing gasket is formed between the two clamping strips and the two airbags. Both the clamping strips and the sealing gasket are used for bending.

[0006] Preferably, the bonding part includes a connector and a plurality of bonding bodies, wherein each pair of adjacent bonding bodies is hinged by a movable head, and the two movable heads near the connector are rotatably connected to the connector by a pin.

[0007] Preferably, the locking part includes two sets of movable parts, two fixed heads, a threaded post, and a nut. The two sets of movable parts are rotatably connected to their adjacent mating bodies by a pin. The two fixed heads are rotatably connected to the two sets of movable parts respectively. The threaded post passes through the two fixed heads and is slidably connected to the two fixed heads. The nut is threadedly connected to the threaded post.

[0008] Preferably, the locking strip assembly includes a locking strip A and two locking strips B. The locking strip A is engaged with the two locking strips B, the locking strips B are in contact with the airbag, and both locking strips A and B are in contact with the inner wall of the sealing gasket. A gap is left between one side of the locking strip A and the inner wall of the two locking strips B.

[0009] Preferably, the airbag includes a rectangular elastic pad, two straight plates, several protrusions A, two protrusions B, and two protrusions C. The elastic pad is fixed to the two straight plates, one of which is fixed to its adjacent fitting body and to several protrusions A. The other straight plate is in contact with a sealing gasket. The two protrusions C are respectively fixedly connected to the two inner sidewalls of the elastic pad. The protrusions B are in contact with protrusions A and C. Both protrusions B are slidably connected to the straight plates. The cross-sections of protrusions A, B, and C are all arc-shaped.

[0010] Compared with the prior art, this utility model has the following advantages: By setting a clamping mechanism with a fitting part and a locking part for fixing, the fitting part is a chain structure, which can wrap the clamping mechanism around the broken part of the water supply pipe according to different pipe diameters through the locking part, and seal the broken part of the water supply pipe through the sealing gasket. Through the set of clamping strips and airbags, when the airbag is compressed, it can apply pressure to the straight plate, so that the straight plate squeezes the sealing gasket, and apply lateral pressure to the clamping strips, thereby increasing the contact force between the clamping strips and the sealing gasket and preventing the clamping strips from falling off. It can also tighten the sealing gasket to prevent the sealing gasket from loosening and causing water leakage. The two clamping strips and two airbags form a rectangular structure for squeezing the sealing gasket, thereby squeezing the sealing gasket around its perimeter and preventing water leakage. Therefore, when performing emergency repairs on broken water supply pipes, it is only necessary to fix the clamping mechanism to the repair position of the water supply pipe. It not only has a good sealing effect and is simple and quick to operate, but also saves time and effort. Attached Figure Description

Detailed Implementation

[0022] As shown in Figures 1-10, an emergency device for a water supply pipe rupture includes a clamping mechanism 1 and a sealing gasket 2. The clamping mechanism 1 includes a fitting part for fitting the water supply pipe and a locking part for fixing. The locking part includes two sets of movable parts 401, two fixing heads 402, a threaded post 403, and a nut 404. The two sets of movable parts 401 are rotatably connected to the fitting body 302 adjacent to them by a pin. The two fixing heads 402 are rotatably connected to the two sets of movable parts 401 respectively. The threaded post 403 passes through the two fixing heads 402 and is slidably connected to the two fixing heads 402. The nut 404 is threadedly connected to the threaded post 403. By rotating the threaded post 403 and the nut 404, the position between the two fixing heads 402 is fixed, thereby achieving clamping. The fixing mechanism 1 to the water supply pipe has a chain-like fitting structure. The fitting part includes a connector 301 and several fitting bodies 302. Each pair of adjacent fitting bodies 302 are hinged by a movable head 303. The movable head 303 has a circular cross-section at both ends and is rotatably connected to the adjacent fitting bodies 302 by a pin. The two movable heads 303 near the connector 301 are rotatably connected to the connector 301 by a pin, allowing the fitting part to open and fit water supply pipes of different diameters. The locking part is movably installed at the opening of the fitting part. The sealing gasket 2 has a double-folded structure, and the folded edges are fixed to the clamping mechanism 1. The sealing gasket 2 has two clip groups 5 and two airbags 6 installed inside. The clip group 5 includes clip A501. The airbag 6 is fitted with two retaining strips B502. Retaining strip A501 engages with the two retaining strips B502, and retaining strip B502 contacts the airbag 6. Both retaining strips A501 and B502 contact the inner wall of the sealing gasket 2. The overall bending radius of retaining strip A501 and the two retaining strips B502 relative to the retaining strip assembly 5 is relatively low to prevent breakage when the retaining strip assembly 5 bends under stress. A gap is left between one side of retaining strip A501 and the inner wall of the two retaining strips B502, preventing interference between them. The retaining strip assembly 5 is also easy to assemble and disassemble. The airbag 6 includes a rectangular elastic pad 601, two straight plates 602, several protrusions A603, two protrusions B604, and two protrusions C605. The elastic pad 601 engages with the two... A straight plate 602 is fixed, one of which is fixed to its adjacent fitting body 302 and to several protrusions A603. The other straight plate 602 is in contact with the sealing gasket 2. Two protrusions C605 are respectively fixedly connected to the two inner sidewalls of the elastic pad 601. Protrusion B604 is in contact with protrusions A603 and C605, and both protrusions B604 are slidably connected to the straight plate 602. The cross-sections of protrusions A603, B604, and C605 are all arc-shaped. When the airbag 6 is compressed, the two straight plates 602 move closer to each other, causing protrusion A603 to squeeze protrusion B604 and move along the straight plate 602, squeezing protrusion C605, so that protrusion C605 squeezes the elastic pad 601.A rectangular structure for compressing the sealing gasket 2 is formed between the two clamping strip assemblies 5 and the two airbags 6. The clamping strip assemblies 5 are in contact with both the clamping mechanism 1 and the sealing gasket 2, and both the clamping strip assemblies 5 and the sealing gasket 2 are designed for bending.

[0023] Working principle:

[0024] First, align the sealing gasket 2 with the rupture location of the water supply pipe. Since the pipe has a circular cross-section, the clamping mechanism 1 can wrap around the water supply pipe and the sealing gasket 2. Then, insert the threaded rod into the two fixing heads 402 and tighten the threaded rod with the nut 404. At this time, the clamping mechanism 1 forms an encircling shape, and several fitting bodies 302 will fit tightly against the outer ring of the pipe. The sealing gasket 2 is located between the pipe and the clamping mechanism 1. Under the squeezing action of the clamping mechanism 1 and the water supply pipe on the sealing gasket 2, the sealing gasket 2 bends along the pipe wall of the water supply pipe, covering the rupture of the water supply pipe. The size of the sealing gasket 2 should be larger than the size of the pipe rupture, completely covering the rupture. Moreover, the fitting part is a chain structure, so that when the clamping mechanism 1 clamps and fixes water supply pipes of different diameters, several fitting bodies 302 always keep in contact with the pipe, so that the clamping mechanism 1 can be used for water supply pipes of different diameters.

[0025] Following this, when the clamping mechanism is fixed to the water supply pipe, it can also compress the two clamping strips 5 and the two airbags 6 through the squeezing force with the pipe. During this process, the clamping mechanism 1 drives the straight plate 602, which is close to it, to move. The straight plate 602 drives several protrusions A603 to move. Since the cross-sections of protrusions A603, B604, and C605 are all arc-shaped, two protrusions A603 can push two protrusions B604 away from each other and move towards protrusion C605. The two protrusions B604 respectively drive two protrusions C605. 05. The two protrusions C605 press against the two inner walls of the elastic pad 601, making the elastic pad 601 tightly pressed against the two clamping strips 5. The two clamping strips 5 are also tightly pressed against the inner wall of the sealing gasket 2. This improves the stability between the two and tightens the sealing gasket 2 to enhance its sealing effect at the pipe rupture, as shown in Figure 9. Figure 9 is a schematic diagram of the contact body 302 in the clamping mechanism 1 when it is in contact with the clamping strips 5. When the straight plate 602 moves to the same side as the clamping strips 5, the clamping mechanism 1 and the clamping strips 5... 5. Upon contact, the clamping mechanism 1 compresses the two locking strip assemblies 5, causing them to bend along the direction of the sealing gasket 2. It should be noted that, as shown in Figures 2 and 7, since the locking strip assembly 5 is composed of locking strips A501 and B502, the bending amplitude of locking strips A501 and B502 is relatively lower than the overall bending amplitude of the locking strip assembly 5, preventing excessive bending and damage. As the tightening force between the threaded rod and the nut 404 increases, the pressure of the clamping mechanism 1 on the two locking strip assemblies 5 and the airbag 6 increases. When protrusion A603 applies pressure to protrusion B604... The protrusion B604 can also apply pressure to another straight plate 602. The straight plate 602 and the clamping strip group 5 work together to apply pressure to the sealing gasket 2. Moreover, the rectangular structure formed between the two clamping strip groups 5 and the two airbags 6 can compress the contact part of the sealing gasket 2 to form a rectangular sealing point, preventing water from leaking between the water supply pipe and the sealing gasket 2, thus improving the sealing ability. In summary, it is only necessary to wrap the pipe rupture with the clamping mechanism 1 and tighten the locking part to seal the rupture through the sealing gasket 2. This is convenient, quick, time-saving, labor-saving, and has a good sealing effect.
