Technical Field

[0001] This utility model relates to the field of drainage pipeline technology, and in particular to a pipeline connection structure for municipal water supply and drainage construction. Background Technology

[0002] Drainage pipes are a type of piping system used to guide and discharge water. They are an important part of urban infrastructure, responsible for collecting, transporting, and treating water to prevent flooding, protect the environment, and maintain public health.

[0003] When installing existing drainage pipes, construction workers generally need to accurately align the flanges of the two pipes before tightening the bolt assembly. The entire process requires manual support for both sets of pipes, which is cumbersome and difficult to align accurately.

[0004] Therefore, in response to the problem of cumbersome and inaccurate docking of drainage pipes, this utility model uses a positioning and plugging assembly to dock two sets of drainage pipes. After providing alignment and limiting support for the two sets, subsequent bolt tightening is performed, making the operation more convenient and eliminating the need for multiple alignment and adjustment of the installation positions of the two sets of drainage pipes. Utility Model Content

The first pair of pipes is located on the side of the second pair of pipes. A portable connection mechanism is installed between the first pair of pipes and the second pair of pipes. An auxiliary sealing mechanism is provided inside the first pair of pipes. A buffer protection mechanism is provided on the side of the auxiliary sealing mechanism. A positioning support ring is fixedly installed on the inner wall of the side of the second pair of pipes near the position of the first pair of pipes. An abutment strip is fixedly installed circumferentially on the outer wall of the side of the positioning support ring. The positioning support ring is slidably installed inside the first pair of pipes, and an abutment groove is correspondingly opened on the inner wall of the side of the first pair of pipes for the abutment strip to be inserted and installed.

[0007] Preferably, the portable docking mechanism includes a first support bar, a second support bar, a first threaded groove, a second threaded groove, a fastening bolt, and a nut block. The first support bar is symmetrically fixedly installed on the outer side wall of the first connecting pipe near the position of the second connecting pipe. The second support bar is symmetrically fixedly installed on the outer side wall of the second connecting pipe near the position of the first connecting pipe. The top outer wall of the first support bar is symmetrically provided with a first threaded groove. The top outer wall of the second support bar is provided with a second threaded groove. The fastening bolt is installed inside the first threaded groove and the second threaded groove. The bottom end of the fastening bolt is correspondingly installed with a nut block.

[0008] Preferably, the top outer wall of the first support strip is in contact with the bottom outer wall of the second support strip, and the length of the first support strip is greater than the length of the second support strip.

[0009] Preferably, the auxiliary sealing mechanism includes an auxiliary mounting ring and an elastic sealing ring. The auxiliary mounting ring is fixedly installed on the inner wall of the first connecting pipe. The outer side wall of the auxiliary mounting ring is provided with a placement groove for the elastic sealing ring to engage and install. The cross-section of the elastic sealing ring is set as a transverse "I" shape.

[0010] Preferably, the buffer protection mechanism includes a positioning mounting ring, a protective ring, a baffle, a positioning T-block, a positioning T-groove, and a buffer spring. Two sets of positioning mounting rings are fixedly installed on the inner wall of the first connecting pipe near the water inlet. A protective ring is slidably installed on the inner wall of the positioning mounting ring. A baffle is fixedly installed on the inner wall of the protective ring. A positioning T-block is fixedly installed on the outer wall of the protective ring away from the baffle. A positioning T-groove is correspondingly opened on the inner wall of the first connecting pipe for the positioning T-block to slide on. A buffer spring is installed between the outer wall of the positioning T-block and the inner wall of the bottom of the positioning T-groove.

[0011] Preferably, the baffle is configured as a semi-circular structure, and the outer side wall of the baffle is configured as an arc-shaped structure, and the two sets of baffles are installed facing each other.

[0012] Preferably, the length of the protective ring is greater than twice the groove spacing of the positioning T-shaped groove, and the initial sliding end of the positioning T-shaped block is located on the water inlet side of the first pair of pipes.

[0013] The beneficial effects of this utility model are:

[0014] 1. When using this municipal water supply and drainage construction pipe connection structure, two sets of drainage pipes are connected and installed by setting up positioning plug-in components. After the two sets are aligned and limited by support, the subsequent bolt tightening installation process is carried out. The operation is more convenient and there is no need to adjust the installation position of the two sets of drainage pipes multiple times. Furthermore, the bolt components of this device are set to be installed longitudinally, which is inconsistent with the water flow path, so that they are not easy to loosen during subsequent use. At the same time, the positioning support ring is inserted into the inside of the drainage pipe, which enhances the load-bearing capacity and stability of the connection part of the two sets of drainage pipes. The overall structural design is ingenious and has good practical effect.

[0015] 2. When in use, this municipal water supply and drainage construction pipeline connection structure, by installing two sets of semi-circular baffles interlaced inside the water inlet pipe and supporting them with spring assemblies, can significantly improve the fluid flow characteristics and the overall performance of the pipeline. At the same time, under turbulent conditions, the semi-circular baffles can effectively disperse the impact force of the water flow through their blocking effect, and the movement trajectory of the semi-circular baffles compresses the springs, thereby absorbing the impact force of the water flow and achieving a safety protection effect for the pipeline. The overall structural design is ingenious and has good practical effect. Attached Figure Description

[0024] 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.

[0025] Please see Figures 1-7 This utility model provides a technical solution: a pipe connection structure for municipal water supply and drainage construction, including a first pair of pipes 1 and a second pair of pipes 2. The first pair of pipes 1 is located on the side of the second pair of pipes 2. A portable connection mechanism 3 is installed between the first pair of pipes 1 and the second pair of pipes 2. An auxiliary sealing mechanism 4 is provided inside the first pair of pipes 1. A buffer protection mechanism 5 is provided on the side of the auxiliary sealing mechanism 4. A positioning support ring 301 is fixedly installed on the inner wall of the side of the second pair of pipes 2 near the position of the first pair of pipes 1. An abutment strip 302 is fixedly installed circumferentially on the outer wall of the side of the positioning support ring 301. The positioning support ring 301 is slidably installed inside the first pair of pipes 1. Abutment slots 303 are correspondingly opened on the inner wall of the side of the first pair of pipes 1 for inserting the abutment strip 302. The abutment strip 302 and the abutment slots 303 are set here to facilitate the initial positioning and support of the first pair of pipes 1 and the second pair of pipes 2.

[0026] The portable docking mechanism 3 includes a first support bar 304, a second support bar 305, a first threaded groove 306, a second threaded groove 307, a fastening bolt 308, and a nut block 309. The first support bar 304 is symmetrically fixedly installed on the outer side wall of the first connecting pipe 1 near the position of the second connecting pipe 2. The second support bar 305 is symmetrically fixedly installed on the outer side wall of the second connecting pipe 2 near the position of the first connecting pipe 1. The top outer wall of the first support bar 304 has a symmetrical through-hole for the first threaded groove 306, and the top outer wall of the second support bar 305 has an aligned through-hole. There is a second threaded groove 307. Fastening bolts 308 are installed inside the first threaded groove 306 and the second threaded groove 307. A nut block 309 is installed at the bottom end of the fastening bolt 308. The top outer wall of the first support bar 304 fits against the bottom outer wall of the second support bar 305. The length of the first support bar 304 is greater than the length of the second support bar 305. Here, the first support bar 304 and the second support bar 305 are set to different lengths so that both can be installed firmly and provide basic protection for the subsequent fastening installation of the bolt assembly.

[0027] The auxiliary sealing mechanism 4 includes an auxiliary mounting ring 401 and an elastic sealing ring 402. The auxiliary mounting ring 401 is fixedly installed on the inner wall of the first connecting pipe 1. The outer side wall of the auxiliary mounting ring 401 is provided with a placement groove for the elastic sealing ring 402 to be engaged and installed. The cross-section of the elastic sealing ring 402 is set as a transverse "I" shape. The cross-section of the elastic sealing ring 402 is set as a transverse "I" shape so that half of the ring can be stably installed inside the placement groove, while the other half of the ring can be located on the side of the auxiliary mounting ring 401 for deformation resistance support. This achieves the effect of deformation resistance sealing for the support gap between the first connecting pipe 1 and the positioning support ring 301.

[0028] The buffer protection mechanism 5 includes a positioning installation ring 501, a protective ring 502, a baffle 503, a positioning T-shaped block 504, a positioning T-shaped groove 505, and a buffer spring 506. Two sets of positioning installation rings 501 are fixedly installed on the inner wall of the first pair of pipes 1 near the water inlet. The protective ring 502 is slidably installed on the inner wall of the positioning installation ring 501. The baffle 503 is fixedly installed on the inner wall of the protective ring 502. The positioning T-shaped block 504 is fixedly installed on the outer side wall of the protective ring 502 away from the baffle 503. The inner side wall of the first pair of pipes 1 is correspondingly provided with a positioning T-shaped groove 505 for the positioning T-shaped block 504 to slide on. A buffer spring 506 is connected between the outer side wall of the positioning T-shaped block 504 and the inner wall of the bottom of the positioning T-shaped groove 505.

[0029] The baffle 503 is designed as a semi-circular structure, and the outer wall of the side of the baffle 503 is designed as an arc-shaped structure. The two sets of baffles 503 are installed opposite each other. The staggered position blocking effect can effectively buffer the impact force of the water flow, thereby achieving support and protection for the first connecting pipe 1. The arc-shaped structure of the outer wall of the baffle 503 facilitates the guidance of the water flow. The design of reducing the resistance of the flow diameter surface allows the water flow to flow normally.

[0030] The length of the protective ring 502 is greater than twice the groove spacing of the positioning T-slot 505. The initial sliding end of the positioning T-block 504 is located on the water inlet side of the first pair of pipes 1. The design that the length of the protective ring 502 is greater than twice the groove spacing of the positioning T-slot 505 ensures that the protective ring 502 can completely cover the positioning T-slot 505 no matter how the positioning T-block 504 slides inside the positioning T-slot 505, thereby preventing water from entering the positioning T-slot 505 and soaking the buffer spring 506 for a long time. The initial sliding end of the positioning T-block 504 is set on the water inlet side of the first pair of pipes 1 so that it can smoothly pass through the movement trajectory to achieve the effect of buffering and protecting against the impact of water flow. It should be noted that there is friction between the positioning T-block 504 and the positioning T-slot 505, which slows down the positioning T-block 504 through the interference of frictional resistance and prevents it from being too fast during the subsequent rebound process.

[0031] Working principle: Refer to the instruction manual. Figure 1 -Appendix Figure 4 As shown, when the first pair of connecting pipes 1 and the second pair of connecting pipes 2 need to be installed together, the second pair of connecting pipes 2 should first be adjusted to a suitable position and then its side abutment strip 302 should be pushed into the corresponding abutment groove 303. When the abutment strip 302 moves to the bottom of the abutment groove 303, the positions of the first thread groove 306 and the second thread groove 307 should coincide. Then, the fastening bolt 308 should be used to pass through the second thread groove 307 and the first thread groove 306 in a vertical downward direction. Then, the nut block 309 should be tightened to the outside of the fastening bolt 308 in a bottom-up direction to complete the locking installation of the first support bar 304 and the second support bar 305, thereby completing the installation of the first pair of connecting pipes 1 and the second pair of connecting pipes 2.

[0032] See the attached instruction manual. Figure 5 As shown, when the second pair of pipes 2 moves, it will also automatically drive the positioning support ring 301 to move. When the positioning support ring 301 comes into contact with the elastic sealing ring 402 during the movement, the elastic sealing ring 402 will deform accordingly under the squeezing action of the positioning support ring 301 and fill the gap between the positioning support ring 301 and the first pair of pipes 1, thereby achieving the effect of auxiliary sealing.

[0033] See the attached instruction manual. Figure 6 -Appendix Figure 7 As shown, when the water flows into the first pair of pipes 1 with a large impact force, the baffle 503 automatically moves in the direction of the water flow due to the impact of the water flow. When the baffle 503 moves, it will automatically drive the protective ring 502 to move. Then, the movement of the protective ring 502 will automatically drive the positioning T-block 504 to slide inside the positioning T-groove 505. At this time, the buffer spring 506 is gradually deformed and contracted by the squeezing action of the positioning T-block 504, and in this process, the impact force of the water flow is consumed. It should be noted that there is friction between the positioning T-block 504 and the positioning T-groove 505, which slows down the positioning T-block 504 through the interference of frictional resistance, and prevents it from being too fast in the subsequent rebound process. Thus, the first pair of pipes 1 is buffered and protected while reducing the impact force of the water flow.

[0034] The above is the entire working process of the device, and all contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0035] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
