Description

Technical Field

[0001] This utility model relates to the field of external protection and pressure resistance technology for pipelines, and in particular to an external protection and pressure resistance structure for pipelines. Background Technology

[0002] Pipeline external protection pressure-resistant structure is a device used to protect pipelines from damage caused by external pressure. This device is widely used in a variety of fields. In urban underground water supply and drainage systems, it can protect pipelines from the impact of ground vehicle loads, building foundation pressure, etc. In long-distance oil and natural gas pipelines, it can resist external pressure caused by soil pressure, geological disasters, etc. In the pipeline system of chemical enterprises, it can prevent pipelines from being damaged by vibration of surrounding equipment, collision of heavy objects, etc.

[0003] The development of cities is inseparable from the construction of water conservancy projects. In the process of constructing water conservancy projects, pipelines are needed for water flow. During the use of pipelines, due to the partial suspension of pipelines, support devices are needed to support the pipelines at the suspension points.

[0004] An existing patent (publication number: CN217874529U) discloses an external pipeline protection support device for water conservancy projects, comprising: a support rod, the bottom of which is fixedly connected to a base, and the top of which is provided with a connecting sleeve; a connecting frame, which is disposed above the support rod and includes a bottom plate and a top plate, with a connecting head disposed below the bottom plate, and the top of the connecting head connected to the bottom of the top plate via a connecting pipe pad; and a fastening plate, which includes a bottom clamping plate and a top clamping plate, and the bottom clamping plate and the top clamping plate are fixedly connected by a second bolt. The top outer side of the support rod is provided with a threaded structure, and the bottom of the bottom plate is rotatably connected to the connecting sleeve, which is threadedly connected to the support rod. This external pipeline protection support device for water conservancy projects facilitates pipeline support, ensures pipeline stability, reduces friction between the pipeline and the support, and facilitates pipeline protection.

[0005] To address the aforementioned issues, existing patents have provided solutions. However, existing external pipe protection structures typically involve directly using bricks or similar materials to protect the pipe from the outside. While this method provides external protection, it is relatively fixed and cannot be customized to protect pipes of different lengths according to actual usage requirements. Furthermore, when installing external pressure-resistant components, only cushioning pads or similar structures are typically used to provide external pressure resistance, resulting in insufficient practicality.

[0006] Therefore, an external protective pressure-resistant structure for pipelines is proposed. Utility Model Content

[0007] The purpose of this utility model is to provide a pipeline external protection and pressure-resistant structure, which can solve the problem that the existing pipeline external protection structures usually use bricks or other materials to directly protect the pipeline. Although this method can protect the outside of the pipeline, the protection method is relatively fixed and cannot be assembled to protect the outside of pipelines of different lengths according to actual use needs. Moreover, when installing the pipeline external pressure-resistant components, only buffer pads or other structures are usually used to resist pressure on the outside of the pipeline, which is not practical enough.

[0008] To achieve the above objectives, this utility model provides the following technical solution: an external protective pressure-resistant structure for pipelines, comprising a left support and a right support, wherein a protective mechanism is fixedly connected to the top of the left support and the right support, and a pressure-resistant mechanism is fixedly connected to the inner wall of the protective mechanism;

[0009] The protective mechanism includes a support ring, a protective frame, an assembly rod, a threaded rod, a reinforcing rib, an anti-corrosion ring, and an inner protective ring. The protective frame is fixedly connected to the top of the left and right supports. The support ring is fixedly connected to the top of the protective frame. The assembly rod is threaded between the left and right supports. The threaded rod is threaded to the inner walls of the protective frame, the left support, and the right support. The reinforcing rib is movably connected to the inner walls of the left and right supports. The anti-corrosion ring is movably connected to the inner wall of the reinforcing rib. The inner protective ring is movably connected to the inner wall of the anti-corrosion ring.

[0010] Preferably, the anti-compression mechanism includes several anti-compression plates, several telescopic rods, springs, and limiting plates. The several anti-compression plates and several telescopic rods are movably connected between the anti-corrosion ring and the reinforcing ribs. The several anti-compression plates and several telescopic rods are arranged in a cross pattern. The springs are sleeved on the surface of the several telescopic rods. The limiting plates are fixedly connected to the telescopic ends of the several telescopic rods.

[0011] Preferably, the inner wall of the inner protective ring is movably connected to an anti-slip ring, and the inner wall of the anti-slip ring is movably connected to a pipe body.

[0012] Preferably, the inner walls of the protective frame, the left bracket, and the right bracket are provided with threaded holes, and the threaded rod is threadedly connected to the inner wall of the threaded hole.

[0013] Preferably, the inner walls of the left and right brackets are threaded with mounting rods, and the inner wall of the reinforcing rib is provided with a mounting groove.

[0014] Preferably, the plurality of telescopic rods are fixedly connected to the inner wall of the mounting groove, and the limiting plate is movably connected to the outer wall of the anti-corrosion ring.

[0015] Preferably, one end of the spring is fixedly connected to the inner wall of the mounting groove, and the other end of the spring is fixedly connected to the top of the limiting plate.

[0016] Preferably, the size of the limiting plate is adapted to the size of the anti-corrosion ring, and the surface of the threaded rod is threaded with a nut.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] 1. This application uses assembly rods, threaded rods and other structures in the protective mechanism to facilitate the assembly and disassembly of the protective structure. It can be flexibly adjusted according to the actual length of the pipeline body to meet the protection needs of pipeline bodies of different lengths. Furthermore, by setting support rings, protective frame anti-corrosion rings and inner protective rings, the pipeline body can be protected as a whole from the outer wall to the top.

[0019] 2. In the pressure-resistant mechanism of this application, the pressure-resistant plate, telescopic rod and spring work together to provide good buffering and pressure resistance when the main body of the pipeline is subjected to external pressure. Compared with the traditional method of using only a buffer pad, the pressure resistance effect and practicality are stronger. Attached Figure Description

[0026] 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.

[0027] Please see Figure 1-5 The present invention provides the following technical solution:

[0031] Specifically, such as Figure 4 , Figure 5As shown, the anti-compression mechanism 2 includes several anti-compression plates 21, several telescopic rods 23, springs 24 and limiting plates 25. The several anti-compression plates 21 and several telescopic rods 23 are movably connected between the anti-corrosion ring 17 and the reinforcing rib 16. The several anti-compression plates 21 and several telescopic rods 23 are arranged in a cross pattern. The springs 24 are sleeved on the surface of the several telescopic rods 23. The limiting plates 25 are fixedly connected to the telescopic ends of the several telescopic rods 23.

[0032] Specifically, such as Figure 1 , Figure 2 As shown, an anti-slip ring 19 is movably connected to the inner wall of the inner protective ring 18, and the pipe body 3 is movably connected to the inner wall of the anti-slip ring 19.

[0033] Specifically, such as Figure 2 , Figure 4 As shown, threaded holes 6 are provided on the inner walls of the protective frame 12, the left bracket 4 and the right bracket 5, and the threaded rod 15 is threadedly connected to the inner wall of the threaded hole 6.

[0034] In this embodiment: by setting four pressure-resistant plates 21, the pressure on the outer wall of the pipeline body 3 can be buffered; by setting four telescopic rods 23 and springs 24, the external pressure on the pipeline body 3 can be buffered in multiple ways; by setting the four pressure-resistant plates 21 and four telescopic rods 23 in a cross arrangement, the springs 24 and pressure-resistant plates 21 can buffer the force on the pipeline body 3 from multiple directions; by setting a limiting plate 25, the force can be transmitted to the anti-corrosion ring 17; by setting a threaded hole 6, the threaded rod 15 can be installed; by setting an anti-slip ring 19, the friction of the pipeline body 3 can be increased, thereby improving the protective and pressure-resistant effect of the pipeline body 3.

[0035] Specifically, such as Figure 2 , Figure 4 , Figure 5 As shown, the inner walls of the left bracket 4 and the right bracket 5 are threaded with mounting rods 13, and the inner wall of the reinforcing rib 16 is provided with mounting grooves 22.

[0036] Specifically, such as Figure 4 , Figure 5 As shown, several telescopic rods 23 are fixedly connected to the inner wall of the mounting groove 22, and the limiting plate 25 is movably connected to the outer wall of the anti-corrosion ring 17.

[0037] In this embodiment: by setting the mounting rod 13, the left bracket 4 and the right bracket 5 can be installed on the ground, improving the stability of the pipe body 3. The telescopic rod 23 and the spring 24 can be installed by opening the mounting groove 22.

[0038] Specifically, such as Figure 5 As shown, one end of the spring 24 is fixedly connected to the inner wall of the mounting groove 22, and the other end of the spring 24 is fixedly connected to the top of the limiting plate 25.

[0039] Specifically, such as Figure 1 , Figure 2 , Figure 5 As shown, the dimensions of the limiting plate 25 are adapted to the dimensions of the anti-corrosion ring 17, and the surface of the threaded rod 15 is threaded with a nut.

[0040] In this embodiment, nuts can be used to limit the connection points of various components of the device, thereby improving the overall stability of the device.

[0041] Working principle: When installing the main body 3 of the pipe, first, the anti-slip ring 19 is placed on the surface of the main body 3 of the pipe, then the inner protective ring 18 is placed on the outside of the anti-slip ring 19. Next, the anti-corrosion ring 17 and the reinforcing rib 16 are installed in sequence. The pressure-resistant plate 21, the telescopic rod 23 and the spring 24 are installed in the corresponding positions. Then, the protective frame 12 is installed on the left support 4 and the right support 5 through the threaded rod 15. After completion, the user can connect the assembly rod 14 to the left support 4 and the right support 5. When the main body 3 of the pipe is impacted, the support ring 11 can directly resist the external impact. Then, the pressure is transmitted to the protective frame 12, which can withstand the impact. The first step is to buffer the impact force, effectively absorb and disperse external pressure, and reduce the direct impact of pressure on the main body of the pipe 3. The left support 4 and the right support 5 can support the main body of the pipe 3, so that the main body of the pipe 3 can be installed firmly on the ground and prevent it from shifting or loosening during operation. Then the pressure is transmitted to the reinforcing rib 16, which can further protect the main body of the pipe 3. Then the pressure is transmitted to the pressure-resistant plate 21, the telescopic rod 23, and the compression spring 24. The pressure-resistant plate 21 can further reduce the pressure, and the elastic deformation of the spring 24 plays a buffering role, thereby protecting the main body of the pipe 3 from damage by external pressure.

[0042] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
