Description

Technical Field

[0001] The present application relates to the field of water supply and drainage pipelines, and in particular to a municipal water supply and drainage pipeline connection structure. Background Art

[0002] Water supply and drainage is part of municipal engineering. Water supply and drainage pipeline engineering is a pipe (channel) system engineering that transports and distributes industrial water supply and drinking water, and collects, transports and discharges industrial wastewater, domestic sewage and rainwater. Water supply and drainage pipeline engineering is an integral part of the water supply and drainage system and plays a vital role in the entire water supply and drainage system.

[0003] During the laying and construction of water supply and drainage pipes, it is necessary to use a pipe connecting structure to connect the water supply and drainage pipes. The pipe connecting structure of the prior art, such as the utility model patent with patent publication number CN219933301U, is used. The connecting groove and the pipe are connected by threads to form a connection structure between the pipe and the connecting component. The first connecting flange and the second connecting flange are locked by locking bolts. The plug-in plate and the plug-in groove are plug-in connected to form a multiple connection structure between the left unit sleeve and the right unit sleeve, thereby forming a split connection structure between multiple pipes, which is more convenient for disassembly and assembly. The first sealing ring and the first sealing groove are connected by a sleeve connection, and the second sealing ring and the second sealing groove are connected by a sleeve connection, which improves the sealing of the connection and reduces leakage at the connection. The connecting rod and the material blocking fence and the upper cover are connected by threads, and the upper cover and the inspection port are connected by threads to form a pipeline inspection structure. The waste residue in the pipeline can be intercepted by the material blocking fence and cleaned regularly to reduce blockage in the pipeline, making maintenance more convenient.

[0004] However, there is still a lack of sealing structure between the pipeline and the left and right unit sleeves, that is, there is a lack of sealing structure between the pipeline and the connecting components, so there is still a risk of medium leakage in the pipeline. Secondly, the specifications of the material blocking fence are relatively small, so the effect of intercepting waste slag in the pipeline is limited. Utility Model Content

[0005] In order to improve the defects in the above-mentioned prior art, the present application provides a municipal water supply and drainage pipe connection structure.

[0006] The present application provides a municipal water supply and drainage pipe connection structure, which adopts the following technical solution:

[0007] A municipal water supply and drainage pipe connection structure comprises a square tube and a circular tube arranged at both ends of the square tube, the square tube and the circular tube are connected in a reducer connection and are an integrated structure, the square tube and the circular tube are connected in a communication manner, the flange of the circular tube is bolted to the flange of the water supply and drainage pipe, and a sealing structure is arranged between the flange of the circular tube and the flange of the water supply and drainage pipe; an interception net is arranged inside the square tube, the interception net is arranged along the radial direction of the square tube and the interception net is adapted to the inner wall of the square tube, the top wall of the square tube is provided with an installation opening for taking out the interception net, and a plugging component is arranged at the installation opening.

[0008] By adopting the above technical solution, the pipe connection structure composed of the square tube and the circular tubes at both ends thereof is an integrated structure, so there is no need to worry about the sealing problem of the pipe connection structure itself, and a sealing structure is set between the flange of the circular tube and the flange of the water supply and drainage pipe, and then fixed by bolts, so the sealing of the connection can be guaranteed, and there is no risk of leakage of the medium in the pipe. Secondly, the interception net can intercept the waste residue in the pipe, and the interception effect is good. The interception net can also be regularly removed from the installation port of the pipe, and the interception net can be cleaned regularly to prevent blockage. The purpose of the plugging component at the installation port is to seal the installation port to prevent the medium in the pipe from leaking out.

[0009] Optionally, the length of the installation port is smaller than the diameter of the square tube; the interception net comprises a main net unit and auxiliary net units arranged on both sides of the main net unit, the auxiliary net units can be telescopically adjusted on the main net unit, when the auxiliary net units on both sides of the main net unit shrink close to the main net unit, the interception net can pass through the installation port, when the auxiliary net units on both sides of the main net unit extend away from the main net unit, the interception net and the inner wall of the square tube are adapted.

[0010] By adopting the above technical solution, the interception net composed of the main net unit and the auxiliary net units at both ends can be flexibly changed in size. That is, when it is necessary to pass through the installation port, the specifications of the interception net can be reduced. When it is installed in the pipeline, the specifications of the interception net can be increased to adapt to the internal space of the square tube, so as to achieve the best effect of intercepting waste slag. In this way, the length of the installation port is designed to be smaller than the diameter of the square tube. The purpose is to reduce the damage to the structure of the square tube, so that the structural strength of the pipeline connection structure itself can be guaranteed.

[0011] Optionally, the main net unit includes an upper frame, a lower frame and a main net body. The main net body is arranged between the upper frame and the lower frame. The auxiliary net unit includes a U-shaped frame and an auxiliary net body. The auxiliary net body is arranged inside the U-shaped frame. The U-shaped frame is slidably arranged inside the upper frame and the lower frame, and extension springs are arranged between the U-shaped frame and the upper frame and between the U-shaped frame and the lower frame. The main net body and the auxiliary net body are staggered and attached to each other.

[0012] By adopting the above technical solution, under the action of the extension springs, the auxiliary net units on both sides of the main net unit always tend to extend away from the main net unit. Therefore, when the interception net needs to pass through the installation opening, the auxiliary net units on both sides of the main net unit can be manually contracted close to the main net unit, so that the specification of the interception net becomes smaller, so as to pass through the installation opening smoothly. After the interception net is installed inside the pipeline, under the action of the extension springs, the auxiliary net units on both sides of the main net unit extend away from the main net unit, so that the specification of the interception net becomes larger. At this time, the interception net fits the inner wall of the square pipe, and the effect of intercepting waste residue reaches the best.

[0013] Optionally, track grooves for embedding the lower frame and the U-shaped frame are arranged on the inner wall of the square pipe.

[0014] By adopting the above technical solution, the purpose of setting the track grooves is to fix the interception net, so that the interception net can stably intercept waste residue in the pipeline.

[0015] Optionally, one end of the U-shaped frame close to the installation opening is arranged in a chamfered structure.

[0016] By adopting the above technical solution, when the interception net needs to be taken out of the pipeline, the chamfered structure plays a guiding role for the automatic contraction of the auxiliary net unit close to the main net unit, so that the specification of the interception net automatically becomes smaller, and the convenience of disassembling the interception net from the pipeline is improved.

[0017] Optionally, a handle is connected and fixed to the upper frame, and the handle extends out of the installation opening.

[0018] By adopting the above technical solution, the purpose of setting the handle is to facilitate the staff to lift the interception net out of the pipeline.

[0019] Optionally, the plugging assembly includes an outer connecting pipe and a plugging cover. The outer connecting pipe is arranged on the top wall of the square pipe and surrounds the installation opening. The plugging cover is bolted to the outer connecting pipe, and a first sealing ring is arranged between the plugging cover and the outer connecting pipe.

[0020] By adopting the above technical solution, the setting of the external pipe raises the installation port, plays a buffering role for the medium in the pipeline, and makes it difficult for the medium in the pipeline to leak out. The setting of the blocking cover and the first sealing ring is to completely seal the installation port to prevent the medium in the pipeline from leaking out.

[0021] Optionally, the sealing structure is a second sealing ring arranged between the flange of the circular pipe and the flange of the water supply and drainage pipe.

[0022] By adopting the above technical solution, a second sealing ring is provided between the flange of the circular pipe and the flange of the water supply and drainage pipe, so as to improve the sealing effect of the connection between the water supply and drainage pipe and the pipe connection structure, and ensure that there is no risk of medium leakage at the connection.

[0023] In summary, this application includes the following beneficial technical effects:

[0024] 1. The pipe connection structure composed of the square pipe and the circular pipes at both ends is an integrated structure, so the sealing of the pipe connection structure itself can be guaranteed, and a sealing structure is set between the flange of the circular pipe and the flange of the water supply and drainage pipe, and then fixed with bolts. Therefore, the sealing of the connection between the water supply and drainage pipe and the pipe connection structure can be guaranteed, and there is no risk of leakage of the medium in the pipe.

[0025] 2. The interception net can intercept the waste slag in the pipeline, and the interception effect is good. Structurally, the interception net is composed of a main net unit and auxiliary net units on both sides thereof. The auxiliary net units can be telescopically adjusted on the main net unit, that is, the size of the interception net can be flexibly changed. When the interception net needs to pass through the installation port, the auxiliary net units on both sides of the main net unit can be manually retracted close to the main net unit to reduce the size of the interception net. When the interception net is installed into the pipeline, the auxiliary net units on both sides of the main net unit are extended away from the main net unit under the action of the extension spring, so that the size of the interception net becomes larger. At this time, the interception net and the inner wall of the square tube are adapted to achieve the best effect of intercepting waste slag. BRIEF DESCRIPTION OF THE DRAWINGS

Specific embodiments

[0031] The following will Figure 1-4 further elaborate on this application in conjunction with the attached drawings.

[0032] The embodiment of this application discloses a connection structure for municipal water supply and drainage pipes. Referring to Figure 1 and Figure 2 , the connection structure for municipal water supply and drainage pipes is composed of a square pipe 1 with a square radial cross-section and circular pipes 2 with circular radial cross-sections at both ends of the square pipe 1. The square pipe 1 and the circular pipes 2 are connected in a way of variable diameter, and the square pipe 1 and the circular pipes 2 are actually an integral structure. Therefore, both the structural strength and the structural sealing performance of the pipe connection structure can be guaranteed. It should be emphasized here that the diameter of the square pipe 1 is larger than that of the circular pipes 2. The pipe connection structure and the water supply and drainage pipes are bolted together, and a sealing structure is provided at the connection between the two. Specifically, one end of the circular pipe 2 away from the square pipe 1 is a flange structure, and one end of the water supply and drainage pipe connected to the pipe connection structure is also a flange structure. Therefore, the flange of the circular pipe 2 and the flange of the water supply and drainage pipe are paired and bolted together to connect and fix the water supply and drainage pipe to the pipe connection structure. The sealing structure uses a second sealing ring 9 made of silicone material, and the sealing structure is arranged between the flange of the circular pipe 2 and the flange of the water supply and drainage pipe, which can guarantee the sealing effect at the connection between the water supply and drainage pipe and the pipe connection structure, and prevent the medium in the pipe from leaking.

[0033] Referring to Figure 3 and Figure 4An interception net 3 is arranged inside the square tube 1, and an installation opening 11 for taking out the interception net 3 is opened on the top wall of the square tube 1. The interception net 3 and the installation opening 11 are both arranged along the radial direction of the pipeline. For the interception net 3, its structure includes a main net unit 31 and auxiliary net units 32 arranged on both sides of the main net unit 31. The auxiliary net units 32 on both sides of the main net unit 31 can be telescopically adjusted, that is, in the radial direction of the pipeline, the size of the interception net 3 can be flexibly changed, that is, when the interception net 3 is installed inside the square tube 1, the auxiliary net units 32 on both sides of the main net unit 31 can extend in the direction away from the main net unit 31 (the size of the interception net 3 becomes larger), so that the interception net 3 and the inner wall of the square tube 1 are adapted, so that the effect of interception net 3 in intercepting waste slag can be optimized, and when the interception net 3 passes through the installation port 11, that is, when the interception net 3 is being installed or disassembled, the auxiliary net units 32 on both sides of the main net unit 31 can shrink in the direction close to the main net unit 31 (the size of the interception net 3 becomes smaller), so that the interception net 3 can pass through the installation port 11 smoothly.

[0034] Two points need to be emphasized here. One of them is that the interception net 3 is designed to be composed of a main net unit 31 and auxiliary net units 32 on both sides of the main net unit 31, and the size of the specifications can be flexibly changed in the radial direction of the pipeline. The purpose is that the length of the installation port 11 can be designed to be smaller than the diameter of the square tube 1, so that the damage to the structure of the square tube 1 caused by the opening of the installation port 11 can be reduced, so that the structural strength of the pipeline connection structure itself can be guaranteed. Another point is that after the interception net 3 is shrunk, in the process of passing through the installation port 11, in the width direction of the installation port 11, there is enough space for the interception net 3 to take the waste out of the pipeline. In this way, while it is convenient to clean the interception net 3, it is also convenient to take out the waste that has been intercepted by the interception net 3 in the pipeline for a long time.

[0035] Reference Figure 4, specifically, the main net unit 31 is composed of an upper frame 311 with a U-shaped structure, a lower frame 312 with an inverted U-shaped structure, and a main net body 313 arranged between the upper frame 311 and the lower frame 312. The auxiliary net unit 32 is composed of a C-shaped frame 321 with a C-shaped structure and an auxiliary net body 322 arranged inside the C-shaped frame 321. The C-shaped frame 321 is slidably arranged inside the upper frame 311 and the lower frame 312, so that the auxiliary net unit 32 can be telescopically adjusted in the radial direction of the pipeline on the main net unit 31. In addition, extension springs 4 are arranged between the C-shaped frame 321 and the upper frame 311 and between the C-shaped frame 321 and the lower frame 312. Under the action of the extension springs 4, the auxiliary net unit 32 always has a tendency to extend away from the main net unit 31, so that the interception net 3 can better adapt to the inner wall of the square pipe 1 and achieve the best effect of intercepting waste residues. When the interception net 3 passes through the installation opening 11, that is, during the installation or disassembly of the interception net 3, the auxiliary net unit 32 is manually contracted close to the main net unit 31 to make the specification of the interception net 3 smaller. It should be noted here that the upper frame 311 and the lower frame 312 are respectively set into a U-shaped structure and an inverted U-shaped structure, aiming to slidably arrange the C-shaped frame 321 inside the upper frame 311 and the lower frame 312, and the surface of the C-shaped frame 321 that can abut against the inner wall of the pipeline can be flush with the upper frame 311 and the lower frame 312, so as to improve the adaptability of the interception net 3 inside the square pipe 1. The main net body 313 and the auxiliary net body 322 are arranged in an interleaved and mutually attached manner, and avoidance notches for avoiding the auxiliary net body 322 are arranged on the upper frame 311 and the lower frame 312, so as not to hinder the telescopic adjustment of the auxiliary net unit 32.

[0036] Refer to Figure 3 and Figure 4 , further, a track groove 6 for embedding the lower frame 312 and the C-shaped frame 321 is arranged on the inner wall of the square pipe 1. The track groove 6 is actually a groove structure composed of two track plates. The purpose of arranging the track groove 6 is to fix the interception net 3 so that the interception net 3 can stably intercept waste residues in the pipeline. In addition, one end of the C-shaped frame 321 close to the installation opening 11 is set into a chamfer structure 3211. When the interception net 3 needs to be taken out of the pipeline, the chamfer structure 3211 plays a guiding role for the auxiliary net unit 32 to automatically contract close to the main net unit 31, so that the specification of the interception net 3 automatically becomes smaller, improving the convenience of disassembling the interception net 3 from the pipeline. And, a handle 7 is fixedly connected to the upper frame 311, and the handle 7 needs to extend out of the pipeline from the installation opening 11. The purpose of arranging the handle 7 is to facilitate the staff to take out the interception net 3 from the pipeline.

[0037] Refer to Figure 2As for the installation port 11 opened on the top wall of the square tube 1, considering that the medium in the pipeline will leak outward from the installation port 11, a plugging component 5 can be set at the installation port 11. The plugging component 5 includes an external tube 51 and a plugging cover 52. The external tube 51 is set on the top wall of the square tube 1 and is arranged around the installation port 11. The plugging cover 52 and the external tube 51 are bolted, and a first sealing ring 8 is set between the plugging cover 52 and the external tube 51, so that the installation port 11 can be completely sealed to prevent the medium in the pipeline from leaking outward.

[0038] The implementation principle of a municipal water supply and drainage pipe connection structure in an embodiment of the present application is as follows: the interception net 3 can intercept the waste residue in the pipe and has a good interception effect. Structurally, the interception net 3 is composed of a main net unit 31 and auxiliary net units 32 on both sides thereof. The auxiliary net units 32 can be telescopically adjusted on the main net unit 31, that is, the size of the interception net 3 can be flexibly changed. When the interception net 3 needs to pass through the installation port 11, the auxiliary net units 32 on both sides of the main net unit 31 can be manually retracted close to the main net unit 31 to reduce the size of the interception net 3. When the interception net 3 is installed in the pipe, under the action of the extension spring 4, the auxiliary net units 32 on both sides of the main net unit 31 extend away from the main net unit 31 to increase the size of the interception net 3. At this time, the interception net 3 and the inner wall of the square tube 1 are adapted to optimize the effect of intercepting waste residue.

[0039] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
