Simple pipeline fixing device for urban rainwater and sewage

Abstract

This utility model discloses a simple pipe fixing device for urban stormwater and sewage systems, including a mounting base, a placement base, and a rotating ring. The placement base is installed on top of the mounting base, and the rotating ring is rotatably connected to the placement base. It also includes a limiting component and a locking component. The limiting component limits the rotation ring, and the locking component locks the limiting component. This utility model provides a stable and reliable pipe fixing solution. The semi-circular placement base and the arc-shaped rotating ring cooperate to form an annular limiting space, initially restricting pipe movement. The wedge-shaped pressure block, through its inclined surface design, converts vertical pressure into lateral pressure, tightly abutting against the rotating ring. Combined with the anti-slip groove, it increases friction. The U-shaped groove further restricts the rotation tendency of the rotating ring. Multiple limiting mechanisms ensure that the pipe will not shift or fall off due to vibration or external forces.

Description

Technical Field

[0001] This utility model relates to the field of simple urban stormwater and sewage pipe fixing technology, specifically to a simple urban stormwater and sewage pipe fixing device. Background Technology

[0002] Currently, the most common fixing methods for urban stormwater and sewage pipe installation are concrete pouring or simple bracket bolt tightening. For concrete pouring, a formwork is first erected at the pipe installation location, and concrete is poured into the formwork. After the concrete solidifies, a fixed base is formed, achieving long-term pipe fixation. Simple bracket bolt tightening involves wrapping the pipe with a semi-circular or arc-shaped bracket, and then tightening bolts through the lugs on both sides of the bracket, using the preload of the bolts to fix the pipe within the bracket.

[0003] These existing fixing methods have significant shortcomings: concrete pouring is cumbersome, has a long construction period, and cannot be adjusted after fixing. If the pipe is damaged and needs to be replaced, the concrete must be broken up, resulting in high maintenance costs; the bolt tightening force of simple supports is entirely controlled manually, which can easily lead to problems such as loosening causing pipe vibration and displacement, or tightening too much and damaging the pipe. In addition, there is a lack of automatic tightening structure, making operation laborious; poor adaptability, requiring the replacement of supports of corresponding specifications for pipes with different outer diameters, resulting in insufficient versatility and increased procurement costs for construction equipment; poor stability of the fixing structure, with limited contact area between the support and the pipe, and a lack of anti-slip limiting design, making it easy for the support to loosen due to vibration during pipe operation, affecting the fixing effect; at the same time, the disassembly process of existing fixing methods is complicated, requiring the use of wrenches and other tools to loosen multiple bolts, which is time-consuming and laborious, reducing construction and maintenance efficiency. Utility Model Content

[0004] In view of the problems of cumbersome operation, poor adaptability, unstable fixation, inconvenient disassembly and assembly, and high maintenance costs of existing urban stormwater and sewage pipe fixing methods, this utility model provides a simple urban stormwater and sewage pipe fixing device, which realizes rapid and stable fixing and convenient disassembly and assembly of pipes, improves adaptability and operational efficiency, and reduces construction and maintenance costs.

[0005] The technical solution provided by this utility model to solve the above problems is as follows: a simple urban rainwater and sewage pipe fixing device, including a mounting base, a placement base and a rotating ring. The placement base is installed on the top of the mounting base, and the rotating ring is rotatably connected to the placement base. It also includes a limiting component and a locking component. The limiting component is used to limit the rotating ring, and the locking component is used to lock the limiting component.

[0006] More preferably, the placement base is semi-circular.

[0007] More preferably, the rotating ring is arc-shaped.

[0008] More preferably, the limiting component includes a wedge-shaped pressure block, a lifting member, a fixed tube, and a spring. The wedge-shaped pressure block is slidably connected to the upper part of the mounting base, the fixed tube is fixedly connected to the mounting base, the lifting member is slidably connected inside the fixed tube, and a spring is connected between the bottom of the lifting member and the bottom of the fixed tube.

[0009] More preferably, the bottom of the wedge-shaped pressure block is inclined, and an anti-slip groove is provided on the inclined surface of the bottom of the wedge-shaped pressure block.

[0010] More preferably, the wedge-shaped pressure block has a U-shaped groove in the middle.

[0011] More preferably, the locking assembly includes a fixed rod, a limiting rod, an arc-shaped locking plate, and a pull rod. The symmetrically arranged fixed rods are fixed to the upper part of the side wall of the mounting base, and each fixed rod is rotatably connected to an arc-shaped locking plate. The symmetrically arranged limiting rods are fixed to the side of the side wall of the mounting base near the fixed rods. The limiting rods are located inside the arc-shaped locking plate and are used to limit the arc-shaped locking plate. The pull rod is fixed to the top of the lifting component.

[0012] More preferably, the bottom of the arc-shaped locking plate is arc-shaped, and the arc-shaped locking plate locks the bottom of the wedge-shaped pressure block to limit the wedge-shaped pressure block.

[0013] Compared with the prior art, the advantages of this utility model are: the pipe is fixed firmly and reliably. The semi-circular placement seat and the arc-shaped rotating ring cooperate to form an annular limiting space, which initially restricts the movement of the pipe. The wedge-shaped pressure block converts the vertical pressure into lateral pressure through the inclined surface design, which tightly abuts against the rotating ring. The anti-slip groove increases the friction. The U-shaped groove further restricts the rotation tendency of the rotating ring. Multiple limiting measures ensure that the pipe will not be displaced or fall off due to vibration or external force.

[0014] It is simple and efficient to operate, and the automatic clamping is achieved by the elastic force of the spring. No additional pressure is required, saving the physical strength of the operator. The pipe can be fixed and disassembled by simple actions such as rotating the arc-shaped locking plate and pulling the lever. No complicated tools are required, which reduces the difficulty of construction and labor intensity.

[0015] The clamping force is stable and controllable. The elastic return of the spring provides a continuous and uniform clamping force, avoiding uneven clamping force caused by manual operation. This ensures the fixing effect without damaging the pipe due to excessive squeezing, thus extending the service life of the pipe.

[0016] With strong adaptability, it can meet the fixing requirements of rainwater and sewage pipes with different outer diameters. By adjusting the angle of the rotating ring to fit the pipe surface, the automatic clamping design of the wedge-shaped pressure block does not require replacement of the adapter parts, improving the versatility of the device and reducing construction costs.

[0026] Example: As shown in the attached figure, a simple urban stormwater and sewage pipe fixing device includes a mounting base 1, a placement base 2, and a rotating ring 3. The placement base 2 is installed on the top of the mounting base 1 and is semi-circular. The rotating ring 3 is rotatably connected to the placement base 2 and is arc-shaped. The rotating ring 3 cooperates with the placement base 2 to fix the pipe. The device is characterized by further including a limiting component and a locking component. The limiting component is used to limit the rotation ring 3, and the locking component is used to lock the limiting component.

[0027] In this embodiment, the limiting component specifically includes a wedge-shaped pressure block 4, a lifting member 5, a fixed tube 6, and a spring 7. The wedge-shaped pressure block 4 is slidably connected to the upper part of the mounting base 1. The bottom of the wedge-shaped pressure block 4 is inclined, and an anti-slip groove is provided on the inclined surface of the bottom of the wedge-shaped pressure block 4. A U-shaped groove is provided in the middle of the wedge-shaped pressure block 4. During the period when the wedge-shaped pressure block 4 descends to limit the rotating ring 3, if the rotating ring 3 rotates, it will squeeze the wedge-shaped pressure block to deform, rather than push the wedge-shaped pressure block to move upward, thereby improving the stability of the wedge-shaped pressure block in limiting the rotating ring 3. The fixed tube 6 is fixedly connected to the mounting base 1. The lifting member 5 is slidably connected inside the fixed tube 6. A spring 7 is connected between the bottom of the lifting member 5 and the bottom of the fixed tube 6. The initial state of the spring 7 is a stretched state. Furthermore, the locking assembly includes a fixing rod 8, a limiting rod 9, an arc-shaped locking plate 10, and a pull rod 11. The symmetrically arranged fixing rods 8 are fixed to the upper part of the side wall of the mounting base 1. Each fixing rod 8 is rotatably connected to an arc-shaped locking plate 10. The bottom of the arc-shaped locking plate 10 is arc-shaped, and the arc-shaped locking plate 10 engages with the bottom of the wedge-shaped pressure block 4 to limit its movement. The symmetrically arranged limiting rods 9 are fixed to the side wall of the mounting base 1 near the fixing rod 8. The limiting rods 9 are located inside the arc-shaped locking plate 10 and are used to limit the movement of the arc-shaped locking plate 10. After moving downwards, the limiting rod 9 can restrict the arc-shaped locking plate 10, preventing the arc-shaped locking plate 10 from rotating excessively inwards. Then, during the upward resetting of the wedge-shaped pressure block 4, the bottom arc surface of the arc-shaped locking plate 10 will contact the top corner of the wedge-shaped pressure block 4. The top of the wedge-shaped pressure block 4 has an arc-shaped chamfer, which can squeeze the arc-shaped locking plate 10 to rotate outwards until the wedge-shaped pressure block 4 is completely inserted between the arc-shaped locking plates 10. The arc-shaped locking plate 10 swings down and rotates inwards to lock the bottom of the wedge-shaped pressure block 4, thereby limiting the wedge-shaped pressure block 4. The pull rod 11 is fixed to the top of the lifting component 5.

[0028] Before use, place the device on a flat installation area and check the status of each component to ensure that the rotating ring 3 rotates flexibly, the wedge-shaped pressure block 4 slides smoothly, the spring 7 has good elasticity, and the arc-shaped locking plate 10 rotates without jamming, ensuring that the device can operate normally. In the initial state, the arc-shaped locking plate 10 locks the bottom of the wedge-shaped pressure block 4, restricting the downward movement of the wedge-shaped pressure block 4, the spring 7 is in a stretched state, and the lifting component 5 is held in the upper position inside the fixed tube 6.

[0029] Then, rotate the arc-shaped rotating ring 3 upwards to open the upper space of the placement seat 2. The semi-circular placement seat 2 provides stable bottom support for the pipe, preventing lateral displacement during placement. Place the rainwater and sewage pipes smoothly into the placement seat 2. Adjust the angle of the rotating ring 3 according to the outer diameter of the pipe so that its arc-shaped inner wall fits against the pipe surface. The rotating ring 3 and the placement seat 2 cooperate to form a ring-shaped limiting space, initially restricting the movement of the pipe and laying the foundation for subsequent compression and fixation.

[0030] When fixing the pipe, first rotate the arc-shaped locking plate 10 outward to disengage it from the wedge-shaped pressure block 4. After unlocking, the spring 7, which is in a stretched state, returns to its original position and generates a downward pulling force to drive the lifting component 5 to slide down along the fixed pipe 6. The lifting component 5 moves down and drives the wedge-shaped pressure block 4 to move down synchronously. In this way, no additional downward pressure is required. Automatic clamping can be achieved by the elastic force of the spring 7, saving operating strength and ensuring stable clamping force. The limiting rod 9 on the side wall of the mounting base 1 will prevent the arc-shaped locking plate 10 from rotating excessively, thus preventing it from shifting and affecting subsequent locking.

[0031] As the wedge-shaped pressure block 4 moves downward, its inclined bottom surface gradually contacts the outer side of the rotating ring 3. Because the bottom of the wedge-shaped pressure block 4 is inclined and has an anti-slip groove, the inclined design decomposes the vertical pressure into horizontal lateral pressure, causing the wedge-shaped pressure block 4 to press firmly against the rotating ring 3, thus creating a pressure limit and preventing the rotating ring 3 from loosening. The anti-slip groove increases the friction between the wedge-shaped pressure block 4 and the rotating ring 3, preventing relative sliding that could lead to limit failure. Simultaneously, the U-shaped groove in the middle of the wedge-shaped pressure block 4 can restrict the rotation of the rotating ring 3 when it tends to rotate under pipeline pressure, preventing the wedge-shaped pressure block 4 from moving upward, significantly improving the stability of the limit.

[0032] To disassemble or replace the pipe, first pull the lever 11 upwards to move the lifting component 5 upwards along the fixed pipe 6. The spring 7 is stretched again, and the wedge-shaped pressure block 4 moves upwards and releases the pressure limit on the rotating ring 3. Finally, rotate the rotating ring 3 upwards to remove the pipe. The entire operation process requires no complicated tools. The fixing and disassembly of the pipe can be completed by simple actions such as rotation and pulling. It is compatible with rainwater and sewage pipes of different outer diameters, and the structure is stable after fixing, which can effectively resist the vibration of the pipe during operation, prevent the pipe from shifting or falling off, and ensure the stable operation of the urban rainwater and sewage pipe network.

[0033] The above description only illustrates the preferred embodiment of this utility model and should not be construed as limiting the scope of the claims. This utility model is not limited to the above embodiments, and variations in its specific structure are permitted. All changes made within the scope of the independent claims of this utility model are also within the scope of protection of this utility model.
