Description

Technical Field

[0001] This utility model relates to the field of connector technology, specifically to a connector for steel wire mesh reinforced pipes. Background Technology

[0002] Steel wire mesh reinforced polyethylene composite pipe, as a high-end product in the field of pressure pipelines, has pushed the performance of plastic pipes to a new level. It cleverly uses high-strength copper-plated steel wire, wound and woven into a mesh structure using a specific process, as the framework. This design not only greatly enhances the pipe's pressure-bearing capacity but also ensures its flexibility and impact resistance. Simultaneously, the use of high-density polyethylene and a special adhesive resin as the matrix material further improves the pipe's corrosion resistance and service life. Therefore, steel wire mesh reinforced polyethylene composite pipe is particularly suitable for high-pressure, large-diameter water and gas transmission projects, making it the preferred material for many large-scale infrastructure projects.

[0003] However, in practical applications, many pipe connectors lack a loosening detection mechanism. Due to various external factors such as geological changes, temperature variations, and external loads, the connection between two pipes is prone to loosening or displacement. Traditional detection methods often rely on manual inspections, which are not only inefficient but also difficult to detect potential loosening problems in a timely manner. Once a loose connection occurs, it may lead to safety hazards such as leaks and bursts, seriously threatening the normal operation of the pipeline system and the safety of the surrounding environment. Therefore, we propose a new type of connector for steel wire mesh reinforced pipes. Utility Model Content

[0017] Compared with the prior art, the present invention provides a method with the following beneficial effects:

[0018] This invention effectively solves the problem of the lack of a loosening detection mechanism in existing pipe connectors by using a combination of a pipe positioning mechanism and a sealing mechanism, along with a linkage device between a PLC controller and a buzzer.

[0030] In this utility model, unless otherwise stated, the orientations used, such as "up" and "down", usually refer to the direction shown in the accompanying drawings, or to the vertical, perpendicular, or gravitational direction; similarly, for ease of understanding and description, "left" and "right" usually refer to the left and right shown in the accompanying drawings; "inner" and "outer" refer to the inner and outer contours of each component itself, but the above directional terms are not used to limit this utility model.

[0031] This utility model provides a technical solution:

[0032] Please see Figures 1-5 A connector for steel wire mesh reinforced pipes includes a housing 1 and a slot 11 opened inside the housing 1. The inner cavity of the housing 1 is provided with a sealing mechanism 2. Pipe positioning mechanisms 3 are provided at the left and right ends of the housing 1. A PLC controller 4 is fixedly installed on the top of the housing 1. The PLC controller 4 is electrically connected to a buzzer 5 fixedly installed on the housing 1.

[0033] Furthermore, the sealing mechanism 2 includes a base ring 21 fixedly installed at the center of the inner cavity of the outer shell 1. Anti-loosening springs 22 are symmetrically installed on the outer side of the base ring 21. A sealing ring 23 is fixedly installed at the end of the anti-loosening spring 22 away from the base ring 21. A pressure sensor 24 is fixedly installed inside the sealing ring 23. The stability of the sealing ring 23 is enhanced by the anti-loosening spring 22. The pressure sensor 24 inside the sealing ring 23 monitors the pressure changes in real time, thereby effectively detecting the loosening at the pipe connection. This solves the defects of traditional detection methods, such as low efficiency and difficulty in timely detection of loosening problems.

[0034] Furthermore, the outer diameter of the sealing ring 23 is equal to the inner diameter of the outer shell 1. The sealing ring 23 is made of rubber material. By ensuring that the outer diameter of the sealing ring 23 is equal to the inner diameter of the outer shell 1, a tight and seamless seal is ensured. The use of rubber material enhances the sealing performance and elasticity, adapts to minor deformations of the pipeline, effectively prevents pipeline loosening caused by external factors, and ensures the safe operation of the pipeline system.

[0035] Furthermore, there are several pressure sensors 24, which are evenly distributed in a circular shape inside the sealing ring 23. By evenly distributing the pressure sensors 24 inside the sealing ring 23, the pressure condition of the sealing ring can be comprehensively monitored, signs of loosening can be detected in time, the detection efficiency and accuracy can be improved, and safety hazards caused by pipeline loosening can be effectively avoided.

[0036] Furthermore, the pipeline positioning mechanism 3 includes a positioning rod 31 that is slidably connected inside the housing 1. A pressing spring 32 is fixedly installed inside the positioning rod 31, and a locking block 33 is fixedly installed on the top of the pressing spring 32. Through the design of the slidably connected positioning rod 31, pressing spring 32 and locking block 33, the stability and accuracy of the pipeline during the connection process are ensured, effectively responding to external factors such as geological changes and temperature changes, and reducing the risk of loosening or displacement at the pipeline connection.

[0037] A pipe fixing ring 34 is fixedly installed at the end of the positioning rod 31 away from the outer casing 1. A clamping rod 35 is threadedly connected inside the pipe fixing ring 34. A bearing 36 is fixedly installed at one end of the clamping rod 35. A clamping plate 37 is fixedly installed on the side of the bearing 36 away from the clamping rod 35. Through the pipe fixing ring 34 at one end of the positioning rod 31 and its internal clamping rod 35, bearing 36 and clamping plate 37, the steel wire mesh skeleton pipe can be steadily fixed into the pipe fixing ring 34 through the threaded connection and the guidance of the bearing 36, ensuring the stability and safety of the pipe connection process and effectively dealing with the loosening problem.

[0038] Furthermore, the locking block 33 is adapted to the locking slot 11. The adaptation of the locking block 33 to the locking slot 11 ensures a stable connection between the pipe positioning mechanism 3 and the outer shell 1, effectively copes with external factors such as geological changes and temperature changes, reduces the risk of loosening or displacement at the pipe connection, and improves the stability and safety of the connector.

[0039] Furthermore, there are four clamping rods 35, and the included angle between two adjacent clamping rods 35 is ninety degrees. The design of having four clamping rods 35 ensures that the steel wire mesh reinforced pipe is subjected to uniform force during connection, improves the stability and safety of the connection, and effectively addresses the problem of loosening.

[0040] Furthermore, the inner side of the clamping plate 37 is fixedly equipped with several evenly distributed teeth, which can more firmly grip the surface of the steel wire mesh skeleton pipe, enhance connection stability and sealing, effectively address loosening issues, and improve the safety and reliability of the connector.

[0041] In practical use, the working principle of this utility model is as follows:

[0042] When using this connector, first place the two wire mesh reinforced pipes that need to be fixed into the pipe positioning mechanism 3. This pipe positioning mechanism is ingeniously designed to ensure the stability and accuracy of the pipes.

[0043] Next, the distance between the wire mesh reinforced pipe and the sealing mechanism 2 is adjusted, which is a crucial step to ensure a good seal. Through precise adjustment, the distance between the wire mesh reinforced pipe and the sealing mechanism 2 is made smaller than the distance between two adjacent slots 11, preparing for subsequent sealing and fixing operations.

[0044] After the distance between the wire mesh reinforced pipe and the sealing mechanism 2 is adjusted, the clamping rod 35 is rotated. The clamping rod 35 is threaded into the pipe fixing ring 34, and its rotation will cause the clamping plate 37 to move closer to the wire mesh reinforced pipe. With the support and guidance of the bearing 36, the clamping plate 37 can move smoothly without rotating. In this way, the toothed structure on the clamping plate 37 can firmly fix the wire mesh reinforced pipe to the inside of the pipe fixing ring 34, ensuring the stability and safety of the pipe during the connection process.

[0045] After the pipe position is fixed, the positioning rod 31 is operated. The positioning rod 31 and the pipe fixing ring 34 fixed to it are pushed inwards. During this process, the pressing spring 32 is gradually compressed. As the positioning rod 31 moves inwards, the locking block 33 disengages from the slot 11 that was originally away from the sealing mechanism 2. When the locking block 33 moves to the next slot 11 closer to the sealing mechanism 2, due to the restoring force of the pressing spring 32, the locking block 33 quickly springs into this slot 11, thus achieving a stable connection between the pipe positioning mechanism and the outer casing.

[0046] At this point, since the distance between the wire mesh reinforced pipe and the sealing mechanism 2 has been pre-adjusted to be less than the distance between two adjacent slots 11, one end of the wire mesh reinforced pipe will come into close contact with the sealing ring 23 on the sealing mechanism 2 and be compressed. The sealing ring 23 is made of rubber material and has good elasticity and sealing performance. Under the compression, the sealing ring 23 will deform, further filling the tiny gap between the pipe and the sealing mechanism, thereby completing the sealing operation at the joint of the two wire mesh reinforced pipes.

[0047] Meanwhile, the pressure sensor 24 inside the sealing ring 23 monitors the pressure changes on the sealing ring in real time. Once an abnormal pressure or sign of loosening is detected, the pressure sensor immediately transmits a signal to the PLC controller 4. Upon receiving the signal, the PLC controller reacts quickly, controlling the buzzer 5 to sound an alarm, reminding the operator to perform timely inspection and maintenance. In this way, the dual protection of the anti-loosening spring 22 and the pressure sensor further improves the safety and reliability of the connector.

[0048] In summary, this connector for steel wire mesh reinforced pipes, through its unique design and ingenious working principle, not only achieves a stable connection and sealing between two steel wire mesh reinforced pipes, but also features loosening detection and alarm functions. These advantages make this connector widely applicable and valuable in high-pressure, large-diameter water and gas transmission projects.

[0049] The above are merely specific embodiments of this utility model, but the technical features of this utility model are not limited thereto. Any simple changes, equivalent substitutions, or modifications made based on this utility model to solve essentially the same technical problems and achieve essentially the same technical effects are all covered within the protection scope of this utility model.
