Description

Technical Field

[0001] This utility model relates to the field of pipeline connection technology, and in particular to a flexible connection structure for preventing settlement of municipal pipelines. Background Technology

[0002] In municipal drainage and water supply systems, pipelines are prone to displacement due to soil settlement and load changes. Rigid connections are easily broken and leaked. Anti-settlement flexible connection structures can adapt to displacement through flexible deformation and ensure sealing. They are key components for ensuring the stability of the pipeline network and reducing maintenance costs.

[0003] In the existing technology, some anti-settlement connection devices are composed of an aging-resistant flexible sleeve, flanges at both ends, annular seals and fastening bolts. When the pipeline is displaced, the sleeve deforms to absorb the displacement and prevent rupture, and the seals are pressed together to prevent media leakage.

[0004] In some anti-settlement connection equipment, the seals are integrated with the sleeves and flanges or are bonded together. If the seal fails, the entire equipment needs to be disassembled and replaced, which disconnects the pipeline and incurs equipment costs. Although some seals can be replaced individually, all bolts need to be removed and the flanges separated, which is cumbersome and can easily damage the sealing surface, expanding the scope of maintenance. Therefore, a flexible connection structure for anti-settlement of municipal pipelines is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a flexible connection structure for preventing settlement of municipal pipelines, aiming to improve the problem that it is difficult to quickly replace the sealing ring in some existing flexible connection structures for preventing settlement of municipal pipelines.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A flexible connection structure for preventing settlement of municipal pipelines includes a flexible pipe, with sealing mechanisms fixedly connected to both the left and right sides of the flexible pipe, and a quick-release mechanism slidably connected to the outside of the sealing mechanism. The sealing mechanism includes a connecting ring, which is fixedly connected to the outside of the flexible tube. Two sealing grooves are fixedly connected to the outside of the connecting ring, and a sealing ring is slidably connected inside the sealing groove. A force-bearing ring is fixedly connected to the outside of the sealing ring, and a clamping assembly is detachably connected to the outside of the force-bearing ring. Preferred: The sealing mechanism formed by the flexible pipe and the connecting rings on both sides can improve the sealing performance of the pipe connection and prevent leakage. The quick-release mechanism has a sliding connection that facilitates quick disassembly and maintenance. In the face of municipal pipeline settlement, the flexible pipe can adapt to deformation. The connecting rings and the quick-release mechanism can slide slightly. The whole can be flexibly adjusted with settlement, reducing the damage of settlement to the pipeline. As a further description of the above technical solution: The clamping assembly includes multiple arc-shaped plates. The interior of each arc-shaped plate is detachably connected to the exterior of the force-bearing ring. A first rotating shaft is rotatably connected to the exterior of each arc-shaped plate. A transmission shaft is fixedly connected to the exterior of each arc-shaped plate. Transmission rods are rotatably connected to both sides of the transmission shaft. A second rotating shaft is rotatably connected to the interior of each transmission rod. Preferred configuration: The multiple arc-shaped plates of the clamping assembly can be flexibly assembled and disassembled to fit the force-bearing ring, adapting to different size requirements and facilitating maintenance. The rotating shaft one, the drive shaft and the drive rod work together to evenly transmit the force, ensuring that the sealing ring is subjected to balanced force. The rotating shaft two drives the drive rod to rotate, and pushes the arc-shaped plates to move along the outer circumference of the force-bearing ring through the drive shaft. The rotating shaft one assists the arc-shaped plates in adjusting their angle, so that the arc-shaped plates can stably press the force-bearing ring, thereby allowing the sealing ring to fit tightly against the sealing groove and improving the sealing reliability. As a further description of the above technical solution: A rotating plate is fixedly connected to the bottom of the second rotating shaft, a limit shaft is rotatably connected to the bottom of the rotating plate, and a wrench is rotatably connected to the outside of the second rotating shaft. Preferably, the rotating plate at the bottom of the rotating shaft 2 cooperates with the limiting shaft to limit the rotation angle and avoid damage to the components due to excessive operation. The external wrench facilitates manual force application, reducing the difficulty of operation. Turning the wrench can drive the rotating shaft 2 to rotate, and the rotating shaft 2 simultaneously drives the rotating plate to rotate around the limiting shaft. Under the constraint of the limiting shaft, the rotating plate stably transmits power to the transmission rod, ensuring that the arc plate evenly presses the force ring, improving the stability and convenience of sealing adjustment. As a further description of the above technical solution: The quick-release mechanism includes a sliding tube, the outside of which is slidably connected to the inside of the sealing mechanism, and the inside of which is slidably connected to an outer tube; Preferred: In the quick-release mechanism, the sliding connection between the sliding tube, the sealing mechanism, and the outer tube not only facilitates the quick disassembly and assembly of the outer tube, but also adapts to pipe displacement. The outer tube can slide along the inside of the sliding tube, and the sliding tube can also move within the sealing mechanism. The dual sliding can flexibly cope with pipe settlement or vibration, reduce structural stress, and improve ease of use and stability. As a further description of the above technical solution: A spring is fitted around the outside of the outer tube, and a limit ring is fixedly connected to the outside of the outer tube. Preferred features: The spring outside the outer tube can buffer the impact force caused by pipe vibration and settlement, and protect the connection structure. The limiting ring can limit the displacement of the spring and the outer tube, and prevent the components from being misaligned. When the pipe is displaced, the outer tube slides, and the spring expands and contracts accordingly to buffer it. The limiting ring plays a blocking role in the sliding of the outer tube, preventing the spring from being excessively deformed or the outer tube from sliding out, and improving the structural stability. As a further description of the above technical solution: The outer tube is slidably connected to the inner tube, and the outer tube is slidably connected to the fixing bead. Preferred configuration: The outer tube and inner tube are slidably connected, which can flexibly adapt to the axial displacement of the pipe. The fixing bead can assist in positioning and reduce the sliding friction between the two. The inner tube can slide along the outer tube to cope with the pipe deformation. The fixing bead can limit the excessive sliding of the inner tube, thereby improving the connection flexibility and structural durability. As a further description of the above technical solution: A delivery pipe is fixedly connected to the outside of the outer tube; Preferred design: The outer pipe is fixedly connected to the delivery pipe, which can stably support and transport the medium, avoid leakage caused by loose connection, and ensure the stability of the medium transportation path. When the pipeline is displaced due to settlement or vibration, the movement of the outer pipe will drive the delivery pipe to make synchronous fine adjustments. The fixed connection prevents relative sliding between the two, ensuring continuous medium transportation and improving the practicality of the structure.

[0007] This utility model has the following beneficial effects: 1. In this utility model, the sealing, fixing and replacement control structure drives the clamping component, wrench and arc plate structure to work. The wrench is turned to make the transmission shaft drive the arc plate to tighten. The rotating plate locks the limit shaft to achieve sealing and fixing. The component can be removed and the sealing ring can be replaced by turning the wrench downward, so as to achieve the function of sealing and fixing the connecting ring and the flexible tube and conveniently replacing the sealing ring.

[0008] 2. In this utility model, the quick connection and disassembly structure of the tube body drives the sliding tube, spring and fixing bead structure to work. The inner tube is inserted into the outer tube to achieve quick installation. The sliding tube makes the fixing bead disengage from the groove of the inner tube and can be pulled out for disassembly. The spring drives the sliding tube to reset and wait for the function, thus achieving the effect of quick connection and disassembly of the inner tube and the outer tube. Attached Figure Description

[0011] 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.

[0012] A flexible connection structure for preventing settlement of municipal pipelines, referring to Figures 1 to 3 The system includes a flexible pipe 1, which connects two sections of municipal pipeline. Its flexibility allows it to adapt to displacement caused by ground settlement, temperature changes, or vibration, preventing the connection from cracking due to rigid stress. It also ensures smooth flow of the internal medium. Sealing mechanisms 2 are fixedly connected to both sides of the flexible pipe 1, enhancing the seal between the flexible pipe 1 and the municipal pipeline to prevent leakage. These mechanisms also connect the flexible pipe 1 to a quick-release mechanism 3, ensuring the stability of the connection. The quick-release mechanism 3 is externally slidably connected to the sealing mechanism 2, enabling rapid installation and disassembly of the flexible connection structure from the municipal pipeline. It allows for quick separation when the pipeline needs repair or replacement, improving construction efficiency. The sealing mechanism 2 includes a connecting ring 21. Its function is to serve as the basic component of the sealing mechanism 2, connecting components such as the sealing groove 22 and the force ring 24 to the flexible tube 1 as a whole, enhancing the structural strength of the end of the flexible tube 1, and providing an installation reference for the sealing ring 23 to ensure accurate sealing position. The connecting ring 21 is externally fixedly connected to the outside of the flexible tube 1, so that the connecting ring 21 and the flexible tube 1 form a whole. When the flexible tube 1 deforms, the connecting ring 21 can synchronously adapt to the displacement, avoiding loosening of the connection due to relative movement, and ensuring the stability of the sealing mechanism 2. The connecting ring 21 is externally fixedly connected to two sealing grooves 22, which provide installation space for the sealing ring 23. The inner wall of the sealing groove 22 restricts the radial movement of the sealing ring 23, ensuring that the sealing ring 23 can deform evenly under pressure, thereby enhancing the sealing effect. Specifically, the flexible pipe 1 connects two pipe sections, using its flexibility to adapt to displacement and prevent breakage. The connecting ring 21 of the sealing mechanism 2 on both sides connects to the flexible pipe 1, and two sealing grooves 22 are provided to install sealing rings 23 to prevent leakage. The external quick-release mechanism 3 facilitates disassembly and assembly. The flexible pipe 1 has a deformation tendency to adapt to displacement, and all components maintain flow and sealing, improving construction efficiency.

[0013] A sealing ring 23 is slidably connected inside the sealing groove 22. Its function is to deform under pressure, tightly fitting the sealing groove 22 against the inner wall of the municipal pipeline, filling the connection gap and preventing media leakage. The design of the double sealing groove 22 and sealing ring 23 further improves sealing reliability. A force-bearing ring 24 is fixedly connected to the outside of the sealing ring 23. Its function is to evenly transmit the pressure applied by the clamping assembly 25 to the sealing ring 23, allowing the sealing ring 23 to deform under all-round force, avoiding localized sealing failure. Simultaneously, its own structure connects to the clamping assembly 25, ensuring an intact pressure transmission path. The force-bearing ring 24 is detachably connected to the outside of the clamping assembly 25. Its function is to apply pressure through mechanical transmission, pushing the force-bearing ring 24 to squeeze the sealing groove 22, causing the sealing groove 22 and sealing ring to... The sealing ring 23 is tightly fitted to achieve a seal, and the pressure can be released by reversing the operation, which is convenient for disassembly and maintenance. The clamping component 25 includes multiple arc-shaped plates 251, which are used to fit the outer contour of the force ring 24 and concentrate the dispersed pressure to the force ring 24, ensuring that the force ring 24 is evenly stressed and avoiding damage to the sealing ring 23 due to excessive local pressure. The inside of the arc-shaped plate 251 is detachably connected to the outside of the force ring 24. The whole can be disassembled by turning the wrench 258. The outside of the arc-shaped plate 251 is rotatably connected to the rotating shaft 252, which serves as the rotation fulcrum of the drive shaft 253, allowing the drive shaft 253 to rotate around the rotating shaft 252, and transmitting the operating force of the wrench 258 to the arc-shaped plate 251 to realize the application and release of pressure. Specifically, the inner sealing ring 23 of the sealing groove 22 is deformed under pressure to prevent leakage, the outer force ring 24 evenly transmits the pressure of the pressing assembly 25, the arc plate 251 of the pressing assembly 25 is connected to the force ring 24, the outer rotating shaft 252 supports the transmission shaft 253, the rotating shaft 252 has a rotation tendency, the double sealing + pressure equalization design improves the sealing performance, the wrench 258 makes disassembly easy, ensuring convenient maintenance.

[0014] A drive shaft 253 is fixedly connected to the outside of the arc-shaped plate 251. Its function is to transmit power, converting the oscillating motion of the drive rod 254 into radial movement of the arc-shaped plate 251, allowing the arc-shaped plate 251 to apply pressure to or release pressure on the force-bearing ring 24. Drive rods 254 are rotatably connected to both sides of the drive shaft 253, transmitting the operating force of the wrench 258 to the drive shaft 253. Through the coordinated action of multiple sets of drive rods 254, multiple arc-shaped plates 251 apply pressure synchronously, ensuring uniform force distribution. A rotating shaft 255 is rotatably connected inside the drive rod 254, serving as a fulcrum connecting the drive rod 254 and the rotating plate 256. This allows the drive rod 254 to rotate around the rotating shaft 255, simultaneously converting the rotational force of the wrench 258 into the oscillating power of the drive rod 254, thus achieving a change in the direction of force. A rotating plate 256 is fixedly connected to the bottom of shaft 255. Its function is to connect rotating shaft 255 and wrench 258, and transmit the rotational motion of wrench 258 to rotating shaft 255. At the same time, the rotation angle is limited by limiting shaft 257 to ensure operation safety. The bottom of rotating plate 256 is rotatably connected to limiting shaft 257, which limits the maximum rotation angle of rotating plate 256 to prevent excessive operation of wrench 258 from damaging the components. It also provides a stable support point for rotating plate 256 to ensure stable power transmission. The wrench 258 is rotatably connected to the outside of rotating shaft 255, which provides a force application point for the operator. By turning wrench 258, rotating shaft 255, transmission rod 254 and other components are driven to tighten or loosen clamping assembly 25. The operation is simple and labor-saving, improving installation and disassembly efficiency. Specifically, the arc plate 251 transmits force through the external drive shaft 253, and the two side drive rods 254 are connected to the drive shaft 253. The rotating shaft 255 is linked with the rotating plate 256. The bottom limit shaft 257 of the rotating plate 256 limits the rotation angle. The wrench 258 is operated with the linkage of the components. The wrench 258 and other components have a tendency to rotate and move, and apply force synchronously to ensure uniform pressure. This makes operation easier and improves the efficiency of disassembly and assembly.

[0015] Reference Figure 1 and Figure 4The quick-release mechanism 3 includes a sliding tube 31, which controls the extension and retraction of the fixing bead 36 by sliding along the axial direction of the sealing mechanism 2, thereby enabling quick locking or unlocking of the quick-release mechanism 3 with the municipal pipeline. It also provides installation space and sliding guidance for components such as the outer tube 32 and spring 33. The outer tube 31 is externally slidably connected to the inside of the sealing mechanism 2, ensuring stable movement of the sliding tube 31 along the sealing mechanism 2 and preventing deviation during operation. This allows for precise control of the state of the fixing bead 36, ensuring reliable locking and unlocking actions. The inner tube 32 is internally slidably connected to the sliding tube 31, serving as the main support component of the quick-release mechanism 3. It provides an installation base for components such as the spring 33, limit ring 34, and inner tube 35, and guides the extension and retraction of the entire quick-release mechanism 3 through its cooperation with the sliding tube 31. A spring 33 is sleeved on the outside of the outer tube 32, providing elastic restoring force to the sliding tube 31. When the sliding tube 31 is not subjected to external force, the elastic force of the spring 33 pushes the sliding tube 31. 1. The fixed bead 36 is kept in the locked position, preventing accidental loosening of the connection and ensuring the stability of the pipe connection. The outer tube 32 is fixedly connected to the limit ring 34, which limits the extension range of the spring 33, prevents the spring 33 from being over-compressed or stretched and damaged, and at the same time prevents the sliding tube 31 from moving excessively, providing a positioning reference for the sliding tube 31 and ensuring that it slides within a preset range. The outer tube 32 is slidably connected to the inner tube 35, which pushes the fixed bead 36 to extend and retract by sliding itself. At the same time, it cooperates with the outer tube 32 to form a double tubular structure, which enhances the overall rigidity of the quick release mechanism 3 and avoids deformation under force. The outer tube 32 is slidably connected to the fixed bead 36, which serves as the locking core component of the quick release mechanism 3: when the sliding tube 31 moves upward under the action of the spring 33, the fixed bead 36 is squeezed outward and inserted into the groove of the inner tube 35 to lock. When the sliding tube 31 moves downward, the fixed bead 36 can retract inward to release the lock and achieve quick disassembly and assembly. Specifically, the sliding tube 31 of the quick-release mechanism 3 slides and extends along the sealing mechanism 2, controlling the fixed bead 36 to extend and retract. The inner sleeve is fitted with the outer tube 32, and the outer spring 33 pushes it to lock. The limiting ring 34 limits the movement of the spring 33 and the sliding tube 31. The inner tube 35 slides and pushes the fixed bead 36. The sliding tube 31 and the inner tube 35 have a sliding tendency, realizing quick locking and unlocking, ensuring a stable connection and efficient disassembly and assembly.

[0016] Reference Figure 1 The outer pipe 32 is fixedly connected to the external conveying pipe 4, which serves as a branch transmission channel for the medium in the municipal pipeline system. It diverts the medium in the main pipeline to a designated area or receives the medium from the branch pipeline and merges it into the main pipeline, thereby realizing the multi-path transport and distribution of the medium. Specifically, it is responsible for media transmission, improving the flexibility of media distribution in municipal pipeline systems, and ensuring transportation efficiency.

[0017] The implementation principle of this application embodiment is as follows: During installation, the connecting ring 21 is connected to the flexible tube 1, and then the sealing ring 23 is placed inside the sealing groove 22. Then, the force ring 24 is used to hold it in place. Then, the clamping assembly 25 is used to fit on the outside. The wrench 258 is pulled upward to make the transmission shaft 253 rotate upward. At the same time, multiple arc plates 251 are tightened by the rotating shaft 252. Then, the wrench 258 is moved to the designated position so that the rotating plate 256 locks the limiting shaft 257 to achieve sealing and fixation. When replacement is required, the entire clamping assembly 25 can be removed directly by pulling the wrench 258 downward. Without the fixation of the clamping assembly 25, the force ring 24 can be removed directly, and then the internal sealing ring 23 can be replaced.

[0018] Connect the inner tube 35 to the inside of the sealing groove 22, and then connect the delivery tube 4 to the outer tube 32. Simply insert the inner tube 35 into the inside of the outer tube 32 to achieve quick installation. When it needs to be removed, slide the sliding tube 31 backward, and then the spring 33 stores the rebound force. When sliding the sliding tube 31, the fixing bead 36 sliding inside the outer tube 32 no longer jams the groove of the inner tube 35, so it can be pulled out directly. Then release the sliding tube 31, and the spring 33 rebounds, so that the sliding tube 31 returns to the initial position, ready to be reconnected at any time.

[0019] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
