Description

Technical Field

[0001] This utility model relates to the field of pipeline connection technology, and in particular to a rainwater and sewage separation pipeline anti-settlement connection structure. Background Technology

[0002] In urban drainage systems, stormwater and sewage separation is a key means to improve sewage treatment efficiency and protect the water environment. In stormwater and sewage separation pipeline systems, pipe connection manholes are important nodes used to connect pipelines with different directions and elevations. Traditional stormwater and sewage separation pipeline connection methods, after installation within pipe connection manholes, reveal many drawbacks when faced with conditions such as ground subsidence and geological changes.

[0003] Ground subsidence can cause a sudden increase in stress at pipe connections, leading to loosening or even breakage of the joints, resulting in sewage leakage and serious pollution to the surrounding environment. Furthermore, the terrain varies in different areas, and the space in pipe connection wells is relatively narrow. In narrow pipe connection wells, it is not convenient to flexibly adjust the height of the pipes at both ends of the joint during pipe installation, which increases the time required for pipe installation and connection and reduces work efficiency. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a rainwater and sewage diversion pipeline anti-settlement connection structure.

[0005] The rainwater and sewage diversion pipeline anti-settlement connection structure provided by this utility model includes: a bearing plate, a pipeline body, fixed supports, a buffer structure, a movable frame, a mounting base, and an adjustment structure. Two pipeline sections are provided on the upper surface of the bearing plate. Fixed supports are provided on both sides of the two pipeline sections. The lower ends of the fixed supports are fixedly connected to the upper surface of the bearing plate. Guide grooves are provided at both ends of the fixed supports near the pipeline. Buffer structures are provided inside the guide grooves at both ends of the fixed supports. The buffer structure includes a sliding block, a guide rod, and a buffer damping spring. A through hole is provided on the upper surface of the sliding block, and a guide rod is slidably connected inside the through hole. Buffer damping springs are sleeved at both ends of the guide rod. A movable frame is provided between the fixed supports on both sides of the two pipeline sections. A mounting base is provided inside the movable frame. An adjustment groove is provided on the inner outer surface of the movable frame. An adjustment structure is provided inside the adjustment groove on the inner outer surface of the movable frame. The adjustment structure includes an adjustment block and a threaded rod. A threaded hole is provided on the upper surface of the adjustment block, and a threaded rod is threadedly connected inside the threaded hole on the upper surface of the adjustment block.

[0006] Preferably, a clamp is fitted on the outer surface of the end where the two pipe sections meet. The sliding blocks in the buffer structure inside the guide groove at the upper and lower ends of the fixed pillars on both sides of the two pipe sections are respectively slidably connected to the guide groove at the upper and lower ends of the fixed pillars on both sides of the two pipe sections. The movable frame between the fixed pillars on both sides of the two pipe sections is respectively fixedly connected to the outer surface of the sliding blocks in the buffer structure inside the guide groove at the upper and lower ends of the fixed pillars on both sides of the two pipe sections. The guide slide rods in the buffer structure inside the guide groove at the upper and lower ends of the fixed pillars on both sides of the two pipe sections are respectively fixedly connected to the top and bottom of the guide groove at the upper and lower ends of the fixed pillars on both sides of the two pipe sections.

[0007] Preferably, the buffer damping spring is fixedly connected to the upper and lower ends of the buffer rubber pads respectively. In the buffer structure inside the guide groove on one side of the upper and lower ends of the fixed support on both sides of the two pipe sections, the buffer damping spring's upper and lower ends of the buffer rubber pads are respectively fixedly connected to the outer surface of the sliding block and the inner wall of the guide groove on one side of the upper and lower ends of the fixed support.

[0008] Preferably, the upper surface of the movable frame has a through hole, and the through hole on the upper surface of the movable frame is connected to the adjusting groove on the inner and outer surfaces of the movable frame.

[0009] Preferably, one side of the mounting base is fixedly connected to the outer surface of the adjusting block, and an arc-shaped placement groove is provided on the side of the mounting base away from the adjusting block. The pipe body is placed inside the arc-shaped placement groove on one side of the mounting base, and a fixing half-ring is hinged to one side of the arc-shaped placement groove. The fixing half-ring is engaged with the outer surface of the pipe body.

[0010] Compared with related technologies, the rainwater and sewage diversion pipeline anti-settlement connection structure provided by this utility model has the following beneficial effects:

[0011] 1. By setting up a buffer structure, the buffer structure is set in the guide groove of the fixed support. When the pipeline is displaced due to settlement, the sliding block slides in the guide groove, compressing or stretching the buffer damping spring. The buffer damping spring absorbs and consumes the energy generated by settlement, which greatly reduces the stress concentration at the pipeline connection, effectively prevents the pipeline from breaking or leaking due to settlement, and improves the stability and reliability of the rainwater and sewage diversion pipeline system.

[0012] 2. By incorporating an adjustment structure, the threaded rod and adjustment block within the structure can be used to easily adjust the height of the mounting base, thereby adjusting the height of the pipe body. This allows the pipe to better adapt to different terrain conditions during installation and enables timely adjustments should the pipe height change later due to settlement or other reasons. This effectively reduces the time required for pipe installation and connection, and improves work efficiency. Attached Figure Description

[0017] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0018] Please refer to the following: Figure 1 , Figure 2 and Figure 3 The system includes: a support plate 1, pipe bodies 2, fixed supports 3, a buffer structure 4, a movable frame 5, a mounting base 6, and an adjustment structure 7. Two pipe body sections 2 are mounted on the upper surface of the support plate 1. The support plate 1 serves as the foundational support component of the entire structure, bearing the weight of the two pipe body sections 2 and other related components, providing a stable installation platform. The pipe body sections 2 are used to transport rainwater or sewage, achieving a diversion function. Fixed supports 3 are installed on both sides of the two pipe body sections 2. The lower ends of the fixed supports 3 are fixedly connected to the upper surface of the support plate 1. Guide grooves are provided at both ends of the fixed supports 3 near the pipe. A buffer structure 4 is installed inside each guide groove at one end of the fixed supports 3. The fixed supports 3 are fixedly connected to the support plate 1, providing support and fixation. The guide grooves at the top and bottom provide space for the installation and sliding of the buffer structure 4 and the movable frame 5. The buffer structure 4 includes a sliding block 8, a guide slide rod 9, and a buffer damping spring 10. The upper surface of the sliding block 8 has a through hole, and the guide slide rod 9 is slidably connected inside the through hole on the upper surface of the sliding block 8. The upper and lower ends of the guide slide rod 9 are respectively fitted with buffer damping springs 10. Movable frames 5 are set between the fixed support columns 3 on both sides of the two pipe sections 2. The movable frame 5 has a mounting seat 6 inside. The inner and outer surfaces of the movable frame 5 have an adjustment groove. The inner and outer surfaces of the movable frame 5 have an adjustment structure 7 inside the adjustment groove. The adjustment structure 7 includes an adjustment block 11 and a threaded rod 12. The upper surface of the adjustment block 11 has a threaded hole, and the threaded rod 12 is threadedly connected inside the threaded hole on the upper surface of the adjustment block 11.

[0019] In the specific implementation process, a clamp 13 is fitted on the outer surface of one end of the two pipe sections 2 where they meet. The clamp 13 is used to strengthen the connection between the two pipe sections 2, improve the firmness and sealing of the connection, and prevent rainwater or sewage leakage. The sliding blocks 8 in the buffer structure 4 inside the guide groove at one end of the upper and lower ends of the fixed support pillars 3 on both sides of the two pipe sections 2 are respectively slidably connected to the guide groove at one end of the upper and lower ends of the fixed support pillars 3 on both sides of the two pipe sections 2. The movable frame 5 between the fixed support pillars 3 on both sides of the two pipe sections 2 is respectively fixedly connected to the buffer structure inside the guide groove at one end of the upper and lower ends of the fixed support pillars 3 on both sides of the two pipe sections 2. The sliding block 8 is located on the outer surface of structure 4. The sliding block 8 slides in the guide groove and is connected to the movable frame 5. It can move with the displacement of the pipe body 2 and plays the role of transmitting displacement. The guide slide rod 9 in the buffer structure 4 is fixedly connected to the top and bottom of the guide groove on one side of the upper and lower ends of the fixed support column 3 on both sides of the two pipe body 2. The guide slide rod 9 provides guidance for the sliding block 8, ensuring that the sliding block 8 slides in a straight line in the guide groove. At the same time, the upper and lower ends are fixedly connected to the top and bottom of the guide groove to provide support for the buffer damping spring 10.

[0020] Among them, the buffer damping spring 10 is fixedly connected to the upper and lower ends of the buffer rubber pads 14 respectively. The buffer damping spring 10 is fixedly connected to the upper and lower ends of the buffer structure 4 inside the guide groove on the upper and lower ends of the fixed support column 3 on both sides of the two pipe body 2. The buffer rubber pads 14 at the upper and lower ends of the buffer damping spring 10 are respectively fixedly connected to the outer surface of the sliding block 8 and the inner wall of the guide groove on the upper and lower ends of the fixed support column 3. When the pipe body 2 settles or shifts, the buffer damping spring 10 plays a role in buffering and shock absorption, absorbing and consuming some energy, reducing the impact force on the pipe, and protecting the pipe connection parts. The buffer rubber pads 14 at both ends further enhance the buffering effect.

[0021] The movable frame 5 has a through hole on its upper surface, which is connected to the adjustment groove on the inner and outer surfaces of the movable frame 5. The movable frame 5 is connected between the fixed support columns 3 to provide installation positions for the mounting base 6 and the adjustment structure 7. At the same time, it can move with the displacement of the pipe body 2 through the connection with the sliding block 8 of the buffer structure 4, ensuring the flexibility of the entire structure.

[0022] The mounting base 6 is fixedly connected to the outer surface of the adjusting block 11 on one side. An arc-shaped placement groove is provided on the side of the mounting base 6 away from the adjusting block 11. The pipe body 2 is placed inside the arc-shaped placement groove on one side of the mounting base 6. A fixing half-ring 15 is hinged to one side of the arc-shaped placement groove. The fixing half-ring 15 is engaged with the outer surface of the pipe body 2. One side of the mounting base 6 is connected to the adjusting block 11, and the arc-shaped placement groove on the other side is used to place the pipe body 2. The pipe body 2 is fixed to the mounting base 6 by the hinged fixing half-ring 15, which serves to fix and support the pipe body 2.

[0023] The lower end of the threaded rod 12 is rotatably connected to the bottom of the adjusting groove on the inner outer surface of the movable frame 5. The upper end of the threaded rod 12 extends through the through hole on the upper surface of the movable frame 5 to the outer surface of the movable frame 5. The threaded rod 12 can rotate inside the through hole on the upper surface of the movable frame 5. A rotating wheel 16 is fixedly connected to one end of the threaded rod 12 extending to the outer surface of the movable frame 5. The rotating wheel 16 makes it convenient for the operator to hold and rotate the threaded rod 12.

[0024] The working principle of this utility model is as follows: When the rainwater and sewage separation pipe is displaced or settles due to ground subsidence or other external forces, the pipe body 2 drives the sliding block 8 in the buffer structure 4 connected to it to slide within the guide groove of the fixed support 3. The sliding block 8 compresses or stretches the buffer damping spring 10. The buffer damping spring 10 absorbs and consumes the displacement energy of the pipe body 2 through its own elastic deformation, playing a role in buffering and shock absorption, reducing the impact force on the pipe, and protecting the pipe connection parts from damage. The movable frame 5 is fixedly connected to the outer surface of the sliding block 8 of the buffer structure 4 on both sides, and moves with the sliding block 8, ensuring the flexibility of the entire structure and allowing the pipe body 2 to move freely within a certain range. When the height of the pipe body 2 needs to be adjusted, the wheel 16 at the upper end of the threaded rod 12 is rotated to make the threaded rod 12 rotate. Since the adjusting block 11 is connected to the threaded rod 12 through the threaded hole, the rotation of the threaded rod 12 drives the adjusting block 11 to move up and down in the adjusting groove on the inner side of the movable frame 5. The up and down movement of the adjusting block 11 drives the mounting seat 6 to move up and down, thereby realizing the adjustment of the height of the pipe body 2 placed in the arc-shaped placement groove of the mounting seat 6 to adapt to different installation requirements or changes in pipe position caused by settlement, etc. The clamp 13 strengthens the connection between the two sections of the pipe body 2, ensuring the sealing and firmness of the pipeline system, preventing rainwater or sewage leakage, and ensuring the normal realization of the rainwater and sewage separation function.

Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
