Description

Technical Field

[0001] The utility model relates to the technical field of water supply and drainage pipeline installation, in particular to a water supply and drainage pipeline leakage blocking device. Background Art

[0002] Water supply projects supply water for living and production to residents and factories, mines, and transportation companies, as well as water for firefighting and road greening. Drainage projects remove human sewage, various wastewater from production, and excess surface water. They consist of drainage pipe systems (or ditches), wastewater treatment plants, and final treatment facilities. In both water supply and drainage systems, pipes need to be laid for the transportation of water. Pipes can be divided into metal pipes, plastic pipes, etc. according to their materials. However, regardless of the material of the pipe, during use, on the one hand, it is subject to external damage, and on the other hand, long-term use and aging will cause defects such as sand holes, causing the pipe to leak at that location. As the leakage continues, the hole will become larger and larger, leading to more serious consequences. In the existing technology, adhesives are usually used to fix the leak or the leak position is cut and the pipe is replaced. The existing methods either have poor repair and sealing effects, or the replacement of the pipe takes a long time and requires water outage, affecting the normal water supply and drainage of residents and factories. Utility Model Content

[0003] In order to solve the technical problems existing in the above-mentioned background technology, the utility model provides a leakage plugging device for water supply and drainage pipes.

[0004] The technical solution of this utility model is as follows:

[0005] A water supply and drainage pipe leak-proof device comprises two hoops, each of which is arranged in a semicircular shape. One end of the two hoops is hinged, and the other end is arranged in an open shape. The position of the opening is fixed by a locking assembly. When the two hoops are locked and fixed, a circular through hole is formed in the middle.

[0006] At least one hoop has a sleeve installed on its outer end surface, and a hole communicating with the sleeve is opened at a corresponding position of the hoop, the hole is blocked with an elastic pad, and the sleeve has an internal thread connected to a tightening bolt through the thread;

[0007] The length of the external threaded portion of the clamping bolt is not less than the length of the sleeve.

[0008] In order to facilitate the compression of the elastic pad onto the leaking hole of the pipeline and improve the sealing effect, a compression column is connected to one end of the compression bolt close to the clamp, and the compression column is smaller than the diameter of the compression bolt.

[0009] The end of the clamping column away from the clamping bolt is configured as a spherical surface.

[0010] In order to prevent multiple leaks from existing in the same area and to enable simultaneous plugging, sleeves are installed on the outer end faces of the two clamps, and at least one sleeve is installed on the outer end faces of the two clamps.

[0011] The specific design of the locking assembly is that the locking assembly includes two locking plates respectively connected to the opening positions of the two hoops, and the two locking plates are bent in directions away from each other and connected to the corresponding hoops;

[0012] A accommodating cavity is formed between the locking plate and the hoop, and a support frame is provided in the accommodating cavity. A connecting groove is provided on the end face of the locking plate, and a locking bolt is installed between the two locking plates through the connecting groove and fixed with the locking nut.

[0013] In order to improve the sealing performance with the pipeline, a sealing cushion is installed in the clamp and is arranged in an arc shape that matches the clamp. The sealing cushion is provided with a through hole corresponding to the channel position.

[0014] In order to improve the stability of the sealing gasket, a plurality of fixing bolts are installed on the outer end surface of the clamp, and the fixing bolts are passed through the sealing gasket to install fixing nuts.

[0015] In order to improve the stability of the connection between the leak-stopping device and the pipeline, two elastic support sheets are installed in the hoop at both ends of the sealing cushion, and the ends of the two elastic support sheets that are close to each other are concave toward the center of the hoop.

[0016] The beneficial effects of the present invention are as follows: the present invention is a leakage-stopping device for water supply and drainage pipes. This scheme arranges two mutually hinged hoops, which are semicircular and can be adapted to the pipe to be plugged. The hoops can be locked to the pipe through the locking assembly, thereby improving the stability of the hoops fixation. Secondly, through the arrangement of the sleeve and the clamping bolt, the clamping bolt can be moved toward the leak on the pipe, and the elastic pad can be pressed to the leak through the clamping column to seal the leak, thereby achieving pipeline plugging. The structure is simple, the operation is convenient and quick, and the sealing effect is good. Finally, through the arrangement of the sealing pad and the elastic support sheet, on the one hand, the sealing pad with a corrugated inner wall increases the friction between the sealing pad and the pipe, and on the other hand, the leak-stopping device is limited by the elastic support sheet, thereby improving the stability of the connection between the leak-stopping device and the pipe.

DETAILED DESCRIPTION

[0026] Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings.

[0027] Example

[0028] As mentioned in the background technology, during the use of water supply and drainage pipes, whether they are damaged by external factors, such as during construction sites or geological surveys and excavations, or due to natural aging during long-term use of the pipes, holes may appear in the pipes, causing leakage. Existing leak plugging methods have many defects. Simple adhesives have poor sealing effects. Cutting the hole positions is troublesome on the one hand, and on the other hand, water needs to be cut off, which affects convenience. Therefore, the inventors used existing components to design and create a new type of pipe leak plugging device, which is described in detail below with reference to the diagrams.

[0029] This embodiment provides a water supply and drainage pipe leak blocking device, see Figure 1 , including two hoops 1, and both are set to be semicircular, the hoop 1 is made of elastic metal, one end of the two hoops 1 is hinged, in this solution, the hinge position adopts a hinge form, and the other end of the hoop 1 is set to be open, and the two hoops 1 can be merged and opened around the hinge point.

[0030] In this embodiment, the opening positions of the two hoop tools 1 are fixed by a locking assembly 2. When the two hoop tools 1 are locked and fixed, a circular through hole 3 is formed in the middle for cooperating and fixing with the pipe to be repaired. In this solution, the locking assembly 2 includes two locking plates 21 respectively connected to the opening positions of the two hoop tools 1, which means that two locking plates 21 are provided in total, which are respectively connected to the two hoop tools 1. The two locking plates 21 are bent in a direction away from each other and connected to the corresponding hoop tools 1, that is, they are both extended and bent toward one side of the connected hoop tool 1, and the two locking plates 21 are respectively connected to the corresponding hoop tools 1. 1, an accommodating cavity 22 is formed between the two locking plates 21, and a support frame 23 is provided in the accommodating cavity 22. The support frame 23 is set in a U shape and abuts against the inner side of the hoop 1. Secondly, a connecting groove 24 is opened on the end face of the locking plate 21, and a locking bolt 25 is installed between the two locking plates 21 through the connecting groove 24, and the locking bolt 25 passes through the support frame 23, and then a locking nut 26 is installed at one end of the locking bolt 25 for fixing. By bending the locking plate 21, when the locking bolt 25 and the locking nut 26 are installed and fixed, the accommodating cavity 22 can be squeezed to improve the fixing effect.

[0031] As the main design point of this scheme, at least one outer end surface of the hoop 1 is installed with a sleeve 4, and in this scheme, the outer end surfaces of the two hoop 1 are both installed with a sleeve 4, and at least one outer end surface of the two is installed, so that leaks at different positions can be blocked at different positions, and the diameter of the sleeve 4 can be set to different, and then leaks of different sizes can be blocked. Secondly, combined with Figure 2 The position of the hoop 1 corresponding to the sleeve 4 is provided with a channel 5 that passes through the sleeve 4. The channel 5 is blocked with an elastic pad 6, and the elastic pad 6 is made of transparent material. The use of transparent material facilitates the alignment with the leaking eye after the installation of the hoop 1, and has a certain elasticity. The sleeve 4 is provided with an internal thread, and a tightening bolt 7 is connected through the thread. When sealing the leaking eye, the hoop 1 is fixed to the outer edge surface of the pipe so that the elastic pad 6 is aligned with the leaking eye, and the tightening bolt 7 is rotated and moved toward the side of the hoop 1 until the elastic pad 6 is squeezed inward into the leaking eye of the pipe to complete the sealing.

[0032] It should be noted that the length of the external threaded portion of the clamping bolt 7 is not less than the length of the sleeve 4. In this solution, the length of this portion is greater than the length of the sleeve 4, ensuring that the clamping bolt can push the elastic pad 6 to move.

[0033] On the basis of the above structure, in order to facilitate the compression of the elastic pad 6 on the leaking hole of the pipeline and improve the sealing effect, the clamping bolt 7 is connected to the end close to the clamp 1 with a clamping column 8, and the clamping column 8 is smaller than the diameter of the clamping bolt 7. In addition, the end of the clamping column 8 away from the clamping bolt 7 is set to a spherical surface, and the diameter of the spherical surface is smaller than the diameter of the clamping bolt 7. By setting the spherical surface, the diameter of the clamping column 8 is smaller than the diameter of the elastic pad 6, which facilitates the squeezing of the elastic pad 6 into the leaking hole.

[0034] In this embodiment, combined with Figure 3 and Figure 4 A sealing gasket 9 is installed in the hoop 1, and it is set to an arc shape that matches the hoop 1. The end face of the sealing gasket 9 close to the center of the hoop 1 is set to corrugated. By setting it to corrugated, the sealing gasket 9 has protrusions and grooves, so that when it is squeezed with the pipeline, the friction between the two is increased, and a large area of ​​the pipeline can be sealed, and larger leaks and damages can be sealed. In order to ensure the stable installation of the sealing gasket 9, a plurality of fixing bolts 11 are installed on the outer end face of the hoop 1, and the fixing nuts 12 are installed in the sealing gasket 9, and the fixing nuts 12 are located in the groove of the corrugated sealing gasket 9 and are set to be embedded, so that the installation of the sealing gasket 9 is more stable.

[0035] And, combined with Figure 3 The sealing gasket 9 is provided with a through hole 10 at the position corresponding to the channel 5, so that the tightening bolt 7 can push the elastic gasket 6 through the through hole 10 and counteract the leaking hole of the pipeline.

[0036] On the basis of the above structure, two elastic support pieces 13 are installed in the hoop 1 at both ends of the sealing cushion 9, and mounting grooves 14 are opened at both ends of the hoop 1. Figure 5 As shown, both ends of the hoop 1 have protrusions extending toward the center of the circle, and a mounting groove 14 is formed inside. The elastic support pieces 13 are against the mounting grooves 14, and the ends of the two elastic support pieces 13 that are close to each other are concave toward the center of the circle of the hoop 1, and a serrated groove is provided circumferentially at the tail of the concave portion. When the hoop 1 is fixed to the pipe to be repaired, the pipe can squeeze the concave portion of the elastic support piece 13. By setting the serrated groove, the hoop 1 can be limited, thereby improving the stability of the connection between the hoop 1 and the pipe.
