DETAILED DESCRIPTION

[0039] The embodiments of the present application will be described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to explain the present application, and cannot be understood as a limitation of the present application.

[0040] As shown in Figures 1 to 4 The water supply and drainage connecting device according to an embodiment of the present application is used for connecting the first pipe 1 and the second pipe 2, and comprises a first butt joint sleeve 3, a second butt joint sleeve 4, a sealing assembly 5 and a connection assembly 8.

[0041] The first butt joint sleeve 3 is sleeved on the outer wall of the first pipe 1, and is connected to the end of the first pipe 1 close to the second pipe 2. The end of the first pipe 1 close to the second pipe 2 exceeds the first butt joint sleeve 3 to form a first butt joint portion. The portion of the first pipe 1 exceeding the first butt joint sleeve 3 is regarded as the first butt joint portion, which is relative to the insertion head.

[0042] The second mating sleeve 4 is fitted onto the outer wall of the second pipe 2. The second mating sleeve 4 is connected to the end of the second pipe 2 near the first pipe 1. The end of the second mating sleeve 4 near the first pipe 1 extends beyond the second pipe 2 to form a second mating part that fits into the first mating part. The part of the second mating sleeve 4 that extends beyond the second pipe 2 is used as the second mating part. The plug and the plug hole are plugged into each other relative to the plug hole. At this time, the position where the first mating sleeve 3 and the second mating sleeve 4 abut against the joint or gap between the first pipe 1 and the second pipe 2 is staggered in the axial direction of the pipe. The first mating sleeve 3 and the second mating sleeve 4 can play a structural reinforcement role for the connection part of the first pipe 1 and the second pipe 2, and improve the stability of the structure.

[0043] The sealing component 5 is located between the first mating sleeve 3 and the second mating sleeve 4. That is, the first mating sleeve 3 abuts against one end of the sealing component 5 to form a sealing structure, and the second mating sleeve 4 abuts against the other end of the sealing component 5 to form a sealing structure.

[0044] like Figure 2 As shown, the connecting assembly 8 is used to connect the first mating sleeve 3 and the second mating sleeve 4, and to make the first mating sleeve 3 and the second mating sleeve 4 abut against the sealing assembly 5 to connect and seal the first pipe 1 and the second pipe 2. By connecting the first mating sleeve 3 and the second mating sleeve 4 together through the connecting assembly 8, the first mating sleeve 3 and the second mating sleeve 4 are prevented from shifting in their axial direction, ensuring that the sealing assembly 5 and the corresponding mating sleeve are always in tight contact, thereby improving the sealing performance.

[0045] This embodiment of the invention, by setting a first mating sleeve 3 and a second mating sleeve 4, can form a first mating part and a second mating part that are nested between the first pipe 1 and the second pipe 2. By staggering the mating positions of the first mating part and the second mating part with the mating positions of the first pipe 1 and the second pipe 2, the connection position can be strengthened, improving the stability and safety of the structure. This embodiment of the invention, through the setting of the sealing component 5 and the connecting component 8, can realize the alignment, sealing and connection of the first mating sleeve 3 and the second mating sleeve 4, which is convenient to operate, more practical, and reduces the cost of operation and maintenance.

[0046] The following describes some specific embodiments of the present invention in detail with reference to the accompanying drawings.

[0047] like Figures 1 to 5 As shown, the water supply and drainage connection device of this utility model embodiment is used for connecting the first pipe 1 and the second pipe 2. The water supply and drainage connection device includes a first mating sleeve 3, a second mating sleeve 4, a sealing component 5, and a connecting component 8.

[0048] The first adapter sleeve 3 is sleeved on the outer wall of the first pipe 1 and is connected to the end of the first pipe 1 close to the second pipe 2, and the end of the first pipe 1 close to the second pipe 2 beyond the first adapter sleeve 3 forms a first adapter portion. The part of the first pipe 1 beyond the first adapter sleeve 3 is taken as the first adapter portion relative to the plug-in connector. The second adapter sleeve 4 is sleeved on the outer wall of the second pipe 2 and is connected to the end of the second pipe 2 close to the first pipe 1, and the end of the second adapter sleeve 4 close to the first pipe 1 beyond the second pipe 2 forms a second adapter portion which is sleeved with the first adapter portion; the part of the second adapter sleeve 4 beyond the second pipe 2 is taken as the second adapter portion relative to the plug-in hole, and the plug-in connector and the plug-in hole are connected in plug-in.

[0049] Optionally, the outer wall surface of the first adapter portion (the outer wall surface of the first pipe 1) and the inner wall surface of the second adapter portion (the inner wall surface of the second adapter sleeve 4) are in abutment, which can form structural mutual reinforcement between the pipe and the adapter sleeve, avoid radial misalignment, and improve the stability of the structure.

[0050] At this time, the abutment position of the first adapter sleeve 3 and the second adapter sleeve 4 and the abutment seam or abutment gap between the first pipe 1 and the second pipe 2 are misaligned in the axial direction of the pipe, and the first adapter sleeve 3 and the second adapter sleeve 4 can play a role of structural reinforcement for the connection position of the first pipe 1 and the second pipe 2, thereby improving the stability of the structure.

[0051] The sealing assembly 5 is arranged between the first adapter sleeve 3 and the second adapter sleeve 4, that is, the first adapter sleeve 3 is in abutment with one end of the sealing assembly 5 and forms a sealing structure, and the second adapter sleeve 4 is in abutment with the other end of the sealing assembly 5 and forms a sealing structure.

[0052] Specifically, the sealing assembly 5 includes a first sealing member and a second sealing member, the first sealing member is connected to one of the first adapter sleeve 3 and the second adapter sleeve 4, and the second sealing member is connected to the other of the first adapter sleeve 3 and the second adapter sleeve 4, for example, the first sealing member is connected to the end of the first adapter sleeve 3, the second sealing member is connected to the end of the second adapter sleeve 4, and the first sealing member is provided with a cavity corresponding to the second sealing member to enable the first sealing member and the second sealing member to be clamped.

[0053] When the first adapter sleeve 3 and the second adapter sleeve 4 are in abutment, the second sealing member can be clamped in the cavity of the first sealing member to achieve mutual clamping. At this time, multiple seals can be formed, one is the abutment seal between the first sealing member and the second adapter sleeve 4, and the other is the abutment seal between the second sealing member and the first sealing member, and the sealing structure is in the shape of a broken line, which increases the abutment area of the sealing structure and improves the sealing effect.

[0054] Furthermore, the first seal may not abut against the second mating sleeve 4, or the force exerted by the connecting assembly 8 between the first mating sleeve 3 and the second mating sleeve 4 may be applied more between the first and second seals. The first and second seals may be made of different materials. For example, by adjusting the stiffness and wear resistance of the first and second seals, the stability and service life of the sealing assembly 5 can be better improved.

[0055] In this embodiment, the structure of the sealing component 5 not only increases the strength of the seal but also disperses pressure under high pressure, reducing the risk of the sealing ring loosening and ensuring a long-term stable sealing effect. This structural design significantly reduces the risk of leakage and is suitable for high-pressure, complex fluid transport pipelines.

[0056] When the medium in the pipeline is under high pressure and experiences frequent pressure fluctuations, the cooperation of the first and second seals provides better buffering and protection, preventing the sealing ring from being frequently subjected to direct impact or wear. This embodiment is particularly suitable for environments with frequent vibration and high wear, ensuring the stability of the sealing assembly 5 during long-term use, effectively extending the service life of the sealing assembly 5, reducing replacement and maintenance needs, and improving the overall reliability of the equipment.

[0057] Optionally, the second seal can be a waterproof filler.

[0058] In this embodiment, the length of the first mating part in the axial direction of the first mating sleeve 3 is less than or equal to the sum of the lengths of the second mating part and the sealing component 5 in the axial direction of the first mating sleeve 3. That is, when the first mating part and the second mating part are inserted into place, the first tube 1 and the second tube 2 can just abut together, or a certain length of gap can be reserved between the first tube 1 and the second tube 2 to avoid the first mating part and the second mating part not being able to effectively abut and seal with the sealing component 5 when the first tube 1 and the second tube 2 abut together.

[0059] like Figure 2 and Figure 4 As shown, the connecting assembly 8 is used to connect the first mating sleeve 3 and the second mating sleeve 4, and to abut against the sealing assembly 5 to connect and seal the first pipe 1 and the second pipe 2. There are multiple connecting assemblies 8, arranged circumferentially along the first mating sleeve 3 and the second mating sleeve 4.

[0060] The connecting assembly 8 comprises a plug rod 81, a plug sleeve 7 and a clamping block 84, the plug rod 81 is connected to one of the first butt joint sleeve 3 and the second butt joint sleeve 4, and extends along the axial direction of the first butt joint sleeve 3; the plug sleeve 7 is connected to the other one of the first butt joint sleeve 3 and the second butt joint sleeve 4, and the plug rod 81 is inserted into the plug sleeve 7; the clamping block 84 (limiting piece) is connected between the plug rod 81 and the plug sleeve 7 to prevent the plug rod 81 from being separated from the plug sleeve 7.

[0061] The end of the plug rod 81 is provided with a support 6, and the plug rod 81 is connected to the corresponding first butt joint sleeve 3 or second butt joint sleeve 4 through the support 6. The end of the plug rod 81 close to the plug sleeve 7 is provided with a sliding groove 82, and the clamping block 84 is arranged in the sliding groove 82 and is slidable in the sliding groove 82 to extend out of the sliding groove 82 or retract into the sliding groove 82. A first elastic piece 83 is further arranged between the clamping block 84 and the plug rod 81, and the first elastic piece 83 is a spring. A telescopic rod 85 is arranged in the sliding groove 82, one end of the telescopic rod 85 is connected to the groove bottom of the sliding groove 82, and the other end of the telescopic rod 85 is connected to the clamping block 84. The spring is sleeved on the telescopic rod 85. When the clamping block 84 is pressed, the clamping block 84 retracts into the sliding groove 82, and at this time the plug rod 81 can smoothly pass through the plug sleeve 7. When the clamping block 84 is released, the clamping block 84 extends out of the sliding groove 82 under the action of the spring, thereby preventing the plug rod 81 from being separated from the plug sleeve 7.

[0062] In order to facilitate the plug rod 81 to be inserted into the plug sleeve 7, one side of the clamping block 84 is provided as an inclined slope. When the plug rod 81 is inserted into the plug sleeve 7, as the clamping block 84 approaches the plug sleeve 7, the slope on the clamping block 84 is pressed by the plug sleeve 7 to make the clamping block 84 retract into the sliding groove 82. When the clamping block 84 moves to the other side of the plug sleeve 7, the clamping block 84 will pop out and prevent the plug rod 81 from being separated from the plug sleeve 7.

[0063] Further, the connecting assembly 8 further comprises a fixing plate 86, a sliding plate 87 and a second elastic piece 88. The fixing plate 86 is fixed on the plug rod 81, the sliding plate 87 is sleeved on the plug rod 81 and is movable along the length direction of the plug rod 81, and the second elastic piece 88 is arranged between the fixing plate 86 and the sliding plate 87. The sliding plate 87 and the clamping block 84 are respectively located on the two sides of the plug sleeve 7, and the second elastic piece 88 is a spring.

[0064] In other words, when the first pipe 1 and the second pipe 2 frequently move close to and away from each other in the axial direction due to high-pressure medium or frequent pressure fluctuation, the relative movement between the fixing plate 86 and the sliding plate 87 can be used to compress the second elastic piece 88 to modulate the relative movement of the first pipe 1 and the second pipe 2, reduce the amplitude and frequency of the relative movement of the first pipe 1 and the second pipe 2, reduce the load borne by the sealing assembly 5, stabilize the environment in which the sealing assembly 5 is located, and improve the service life of the sealing assembly 5.

[0065] In this embodiment, the first adapter sleeve 3 and the second adapter sleeve 4 are connected together through the connecting assembly 8, which prevents the first adapter sleeve 3 and the second adapter sleeve 4 from moving in the axial direction, ensures that the sealing assembly 5 is always in close contact with the corresponding adapter sleeve, and improves the sealing performance.

[0066] The flexible combination structure of the insertion rod 81 and the insertion sleeve 7 can realize automatic docking and fixing through the cooperation of the clamping block 84 and the sliding groove 82, and can quickly adapt to pipe interfaces of different shapes and sizes. Not only simplifies the installation process, but also improves the universality and adaptability of the assembly, reduces the need for additional adapters, significantly reduces the installation time and maintenance cost, and helps to cope with complex non-standard pipe connections.

[0067] The embodiment can realize quick repair without shutdown when the pipeline bursts or leaks. Through the quick locking structure of the insertion rod 81 and the insertion sleeve 7, the quick connection of the two ends of the problem pipeline can be realized without stopping water and stopping machine, the system is repaired, and the production continuity is ensured. In the emergency repair scene, the response time is greatly shortened, the production loss is reduced, and the stable operation of the system is effectively guaranteed.

[0068] The water supply and drainage connection system of the embodiment of the utility model, including water supply and drainage connecting device of any above, monitoring device 13, controller, power module and alarm.

[0069] The monitoring device 13 includes a support, a weighing component 131, a water collecting tank 12 and a sheath 9. The weighing component 131 is arranged on the support and includes a pressure sensor for detecting the weight supported thereon. The support includes a bottom plate 11 and a vertical plate 10. The vertical plate 10 is provided with a guide groove 101 extending in the vertical direction. The water collecting tank 12 is provided with a guide block 121 slidingly arranged in the guide groove 101. The sheath 9 is arranged on the outer side of the water supply and drainage connecting device in the circumferential direction. The lower part of the sheath 9 is provided with a through hole 91 corresponding to the water collecting tank 12 in the vertical direction. The water collecting tank 12 is supported on the weighing component 131 and arranged below the water supply and drainage connecting device and the sheath 9 to collect the leaked water.

[0070] The monitoring device 13 is used for collecting and detecting the leaked water of the water supply and drainage connecting device. The controller is used for acquiring the signal of the weighing component 131 and controlling the alarm to alarm. The power module is used for supplying power to the controller, the alarm and the weighing component 131.

[0071] The embodiment integrates a pressure sensor, a controller and an alarm to form real-time water leakage monitoring. When leakage occurs, the system can quickly send an alarm signal to realize real-time monitoring of the sealing effect, timely maintenance and avoidance of adverse effects of water leakage on production and the environment. The embodiment significantly improves the safety and controllability of the pipeline system, helps to deal with the leakage at the early stage, and reduces the maintenance frequency and accident risk.

[0072] The following is described in connection with applications in specific examples.

[0073] Example 1: In a reconstruction project of a large chemical plant water supply and drainage system, the original pipe sealing of the water supply and drainage pipeline in the production area of a chemical plant is poor, and leakage problems occur frequently, resulting in production interruption and safety hazards. The reconstruction involves a total length of 500 meters of drainage pipeline, and requires that the sealing assembly be stable in operation and have real-time monitoring function.

[0074] The working process of the water supply and drainage connection system using the embodiment is as follows: during installation, the insertion rod is inserted into the insertion sleeve, and the clamping block and the sliding groove are automatically clamped to ensure stable connection of the pipe. The waterproof filler and the first sealing ring jointly form double sealing to maintain sealing in a high-pressure environment. The monitoring device monitors the sealing effect in real time, and the alarm immediately sends an alarm once leakage is detected, reminding timely treatment. In continuous testing, the sealing assembly performs stably, and the real-time monitoring system can alarm in time when leakage occurs at the early stage, ensuring the safety of the system and the continuity of production.

[0075] Example 2: In a temporary repair project of a water pipe burst in a production workshop of a factory, the main water supply pipeline in the production workshop suddenly bursts, and a large amount of water leaks. Since the production equipment is running, it cannot be shut down immediately, and temporary repair needs to be carried out without shutdown to prevent production interruption. The water supply and drainage connection system using the embodiment is used for emergency repair. Temporary repair is carried out on the interface of the 100 mm diameter main water supply pipeline, and it is required to complete the temporary closure of the burst interface without shutting down the water supply to ensure the continuous flow of water and avoid production loss caused by shutdown.

[0076] The working process of the water supply and drainage connection system using the embodiment is as follows: first, the burst interface is simply cleaned, and the insertion sleeve is installed and fixed on one side of the damaged pipeline interface. The insertion rod is inserted into the insertion sleeve, and the clamping block and the sliding groove structure are automatically clamped to ensure stable connection. The sealing ring and the waterproof filler form double sealing under the flow pressure to effectively prevent leakage. The entire repair process is completed without stopping water and without stopping machine, successfully suppressing the leakage of the burst point. During the subsequent 72 hours of operation, the sealing effect is stable, and no new leakage occurs, which saves time for subsequent permanent repair and ensures the continuity of production.
