The push block pushes the damping medium to flow through the flow holes to achieve a buffering effect, protecting the main structure of the pipe while reducing damage to the protection component.

Description

Technical Field

[0001] The present invention belongs to the technical field of composite pipelines, and particularly relates to a high-strength steel wire mesh reinforced composite pipeline. Background Art

[0002] The steel wire mesh skeleton plastic composite pipe adopts high-quality materials and advanced production processes, making it have higher pressure resistance performance. At the same time, the composite pipe has excellent flexibility and is suitable for long-distance buried water supply and gas transmission pipeline systems. The pipe fittings used in the steel wire mesh skeleton polyethylene composite pipe are polyethylene electrofusion pipe fittings. During connection, the internal heating element of the pipe fitting is used to melt the outer layer plastic of the pipe and the inner layer plastic of the pipe fitting, and the pipe and the pipe fitting are reliably connected together.

[0003] Chinese Patent CN112303345B discloses a multi-layer steel wire mesh reinforced composite pipe, including a plastic pipe, a reinforcing structure, and a plastic layer; the reinforcing structure wraps the plastic pipe, and the plastic layer wraps the reinforcing structure. The reinforcing structure includes a first bonding resin layer, a first steel wire mesh, a second bonding resin layer, a second steel wire mesh, and a third bonding resin layer. The present invention uses a multi-layer structure formed by superimposing a plastic pipe, a bonding resin layer, and a steel wire mesh. The first bonding resin layer can improve the fixing strength of the first steel wire mesh on the outer surface of the plastic pipe. Both the first steel wire mesh and the second steel wire mesh have a diamond-shaped mesh structure, and are arranged staggered in the vertical direction to form a staggered diamond-shaped mesh structure with a smaller single diamond area. This setting can improve the internal pressure resistance, external pressure resistance strength, and stiffness of the multi-layer steel wire mesh reinforced composite pipe, and the pressure resistance performance is more stable, and it is not easy to lose the pressure resistance strength during use, thereby extending the service life of the multi-layer steel wire mesh reinforced composite pipe.

[0004] The existing high-strength steel wire mesh reinforced composite pipelines have the following disadvantages when transporting normal liquid media:

[0005] 1. A large part of the pipeline is exposed on the ground surface and is easily damaged by impacts such as being knocked down due to accidents or human reasons, especially when under high load, it may cause the pipeline to burst.

[0006] 2. The pipeline will generate a large impact due to the water hammer effect at the moment of water supply or cut-off, and it is easy to cause a large pressure from the inside of the pipeline, especially when the pipeline is aged, it is easy to cause damage. Summary of the Invention

[0007] The purpose of the present invention is to provide a high-strength steel wire mesh reinforced composite pipeline, and its advantage is that it can effectively protect the water supply pipeline, prevent it from being damaged by impact, and can buffer the internal impact of the pipeline, thereby extending the service life of the pipeline.

[0008] The above technical object of the present invention is achieved by the following technical solutions: A high-strength steel wire mesh reinforced composite pipe, including a main pipe structure, on the surface of the main pipe structure, a force-bearing component is bolted, on the side of the force-bearing component away from the main pipe structure, a protection component is bonded, and a buffer component is arranged on the inner wall of the main pipe structure, and the number of the force-bearing components is several.

[0009] Adopting the above technical solutions, by setting the main pipe structure to be used as a transportation pipe for transporting fluid water, the set protection component is used to isolate the main pipe structure from the external environment. When being impacted or bruised, the protection component protects the main pipe structure to avoid direct contact with the impact and cause damage. The force-bearing component is used to buffer the external impact force and connect the protection component and the pipe group structure, and the set buffer component can be used to buffer the impact of the transportation medium inside the main pipe structure.

[0010] The present invention is further set as: The protection component includes a left half shell and a right half shell. The inner walls of the left half shell and the right half shell are bonded to the force-bearing component through cyanoacrylate glue. On the top of the left half shell, a hinge is bolted, and the bottom of the hinge is bolted to the top of the right half shell. The bottom of the left half shell and the bottom of the right half shell are snap-connected.

[0011] Adopting the above technical solutions, by setting the hinge, it is convenient to connect the left half shell and the right half shell, and they can be opened and closed along the hinge for easy installation or disassembly.

[0012] The present invention is further set as: On one side of the bottom of the left half shell close to the right half shell and on one side of the bottom of the right half shell close to the left half shell, accommodation grooves are respectively opened, and superabsorbent resin is arranged inside the accommodation grooves.

[0013] Adopting the above technical solutions, through the cooperation of the set accommodation grooves, the connection part between the left half shell and the right half shell can accommodate superabsorbent resin inside. When the main pipe structure leaks water, the liquid drips onto the inner walls of the left half shell and the right half shell and slides to the position of the superabsorbent resin. The superabsorbent resin swells when contacting water, pushes the left half shell and the right half shell apart, which is convenient for personnel to observe, and they can be removed to repair or replace the main pipe structure.

[0014] The present invention is further configured as follows: The force-bearing component includes a receiving housing, an inner partition plate is bolted to the inner wall of the receiving housing, a pushing block is slidably connected to the inner wall of the inner partition plate, the pushing block is made of rubber material, a plurality of flow holes are formed in the top and bottom of the outer side of the inner partition plate, a return spring is bolted to the surface of the pushing block, the side of the return spring away from the flow hole is bolted to the receiving housing, a connecting rod is bolted to the side of the pushing block away from the return spring, the surface of the connecting rod is slidably connected to the receiving housing, a connecting plate is bolted to the side of the connecting rod away from the pushing block, and the side of the connecting plate away from the connecting rod is bonded to the left half-shell and the right half-shell.

[0015] With the above technical solution, by providing the receiving housing to connect with the main pipeline structure, the inner partition plate is used to separate the internal space of the receiving housing, and the provided pushing block is used to push the damping medium. When an external impact occurs, the left half-shell and the right half-shell transmit the impact to the position of the pushing block through the connecting plate, driving the pushing block to move. The pushing block pushes the damping medium to flow through the flow holes to achieve the damping and buffering effect. After the impact ends, the return spring rebounds to drive the pushing block to rebound.

[0016] The present invention is further configured as follows: The inside of the receiving housing is filled with viscous oil, and limiting rings are bolted to the top and bottom of the inner wall of the inner partition plate, and the surface of the limiting rings is used in cooperation with the pushing block.

[0017] With the above technical solution, by providing the viscous oil as the damping medium and the provided limiting rings to limit the position of the pushing block, it is avoided that the flow holes are blocked due to excessive displacement.

[0018] The present invention is further configured as follows: The buffer component includes a secondary receiving housing, a piston is slidably connected to the inner wall of the secondary receiving housing, a compression spring is bolted to the bottom of the piston, and the bottom of the compression spring is bolted to the secondary receiving housing.

[0019] With the above technical solution, by providing the cooperation of the secondary receiving housing and the piston, when water enters the inside of the main pipeline structure and flows with high impact, the impact acts on the piston, and the piston moves towards the position of the compression spring. Under the action of irregular impact and the continuous force applied by the compression spring, the piston moves in the vertical direction, effectively eliminating the water hammer wave oscillation and avoiding excessive impact on the main pipeline structure.

[0020] The present invention is further configured as follows: A limiting telescopic rod is bolted to the bottom of the piston, and the bottom of the limiting telescopic rod is bolted to the secondary receiving housing.

[0021] With the above technical solution, by providing the limiting telescopic rod, the moving position of the piston can be limited, avoiding rotation or liquid leakage.

[0022] The present invention is further configured as follows: the outer side of the highly absorbent resin is wrapped with a paper packaging bag, and a sealing pad is provided on the side of the top of the left half shell close to the right half shell and on the side of the top of the right half shell close to the left half shell.

[0023] By adopting the above technical solution, a paper packaging bag is provided to wrap the super absorbent resin. When it comes into contact with water, the water will penetrate the paper packaging bag and contact the super absorbent resin, causing it to swell and open the paper packaging bag. The provided sealing pad is used to improve the sealing effect and prevent water in the external environment from accidentally entering the interior of the protective component.

[0024] The present invention is further configured as follows: a buckle is welded on the outer side of the bottom of the left half shell, a clamping block is welded on the outer side of the bottom of the right half shell, and the surface of the clamping block is clamped with the buckle.

[0025] By adopting the above technical solution, by setting the buckles and the blocks, the left half shell and the right half shell can be fixed when they are snapped onto the outside of the main structure of the pipeline. During installation, the super absorbent resin can be placed inside the receiving groove first, and then snapped into place to complete the installation.

[0026] A method for using a high-strength steel wire mesh reinforced composite pipe comprises the following steps:

[0027] S1. Connect the main structure of the pipeline to the water supply position and the water supply position first, then apply cyanoacrylate glue to the connecting plate outside the main structure of the pipeline, open the left half hoop and the right half hoop along the hinge joint, and then snap it onto the outside of the main structure of the pipeline through the snap block, so that the inner walls of the left half hoop and the right half hoop are in contact with the connecting plate and bonded with cyanoacrylate glue;

[0028] S2. When an external impact occurs, it will hit the surface of the left and right half shells. The left and right half shells are buffered by the force-bearing components to reduce the damage. When the water supply is unstable or the valve is opened and closed, the impact of the water flow will be reduced by the buffer component to protect the main structure of the pipeline and the water supply position.

[0029] In summary, the present invention has the following beneficial effects:

[0030] 1. By setting up the protective components, when an external impact occurs, it will hit the left and right half shells. The left and right half shells are buffered by the force-bearing components. The impact is transmitted to the position of the push block through the connecting plate, driving the push block to move. The push block pushes the damping medium to flow through the flow hole to achieve a buffering effect, protecting the main structure of the pipeline while reducing damage to the protective components;

[0031] 2. By setting up a buffer component, when the water supply is unstable or when the valve is opened or closed, the impact acts on the piston. The piston moves towards the position of the compression spring. Under the action of irregular impacts and the continuous force exerted by the compression spring, the piston moves in the vertical direction to reduce the impact, effectively protecting the main structure of the pipeline and the water supply position, and improving the service life of the main structure of the pipeline.

[0043] The present invention will be further described in detail below with reference to the accompanying drawings.

[0044] Example 1:

[0045] Reference Figure 1-10 , a high-strength wire mesh reinforced composite pipe, including a main pipe structure 1, a stress component 2 is bolted to the surface of the main pipe structure 1, and a protective component 3 is bonded to one side of the stress component 2 away from the main pipe structure 1. By setting the main pipe structure 1, it is used as a transportation pipe to transport fluid water. The set protective component 3 is used to isolate the main pipe structure 1 from the external environment. When being impacted or bruised, the protective component 3 protects the main pipe structure 1 to avoid direct contact with the impact and cause damage. The stress component 2 is used to buffer the external impact force and connect the protective component 3 and the pipe group structure.

[0046] As Figure 1 shown, the protective component 3 includes a left half shell 301 and a right half shell 302. The inner walls of the left half shell 301 and the right half shell 302 are both bonded to the stress component 2 by cyanoacrylate glue. A hinge hinge 303 is bolted to the top of the left half shell 301, and the bottom of the hinge hinge 303 is bolted to the top of the right half shell 302. The bottom of the left half shell 301 and the bottom of the right half shell 302 are snap-connected. By setting the hinge hinge 303, it is convenient to connect the left half shell 301 and the right half shell 302, and they can be opened and closed along the hinge hinge 303 for easy installation or disassembly.

[0047] As Figure 9 shown, on one side of the bottom of the left half shell 301 close to the right half shell 302 and on one side of the bottom of the right half shell 302 close to the left half shell 301, accommodation grooves 5 are both opened. A highly absorbent resin 6 is arranged inside the accommodation grooves 5. By setting the accommodation grooves 5 to cooperate, the connection between the left half shell 301 and the right half shell 302 can accommodate the highly absorbent resin 6 inside. When the main pipe structure 1 leaks water, the liquid drips onto the inner walls of the left half shell 301 and the right half shell 302 and slides to the position of the highly absorbent resin 6. The highly absorbent resin 6 swells when it contacts water, pushes the left half shell 301 and the right half shell 302 apart, which is convenient for personnel to observe and remove them to repair or replace the main pipe structure 1.

[0048] As Figure 3As shown, the force-bearing component 2 includes a containing shell 201, the inner wall of the containing shell 201 is bolted with a partition inner plate 202, the inner wall of the partition inner plate 202 is slidably connected with a push block 203, the push block 203 is made of rubber material, and the top and bottom of the outer side of the partition inner plate 202 are provided with a plurality of flow holes 204, the surface of the push block 203 is bolted with a return spring 205, the side of the return spring 205 away from the flow hole 204 is bolted to the containing shell 201, the side of the push block 203 away from the return spring 205 is bolted with a connecting rod 206, the surface of the connecting rod 206 is slidably connected to the containing shell 201, and the side of the connecting rod 206 away from the push block 203 is bolted with a connecting plate 207, the side of the connecting plate 207 away from the connecting rod 206 is bonded to the left half shell 301 and the right half shell 302, and is connected to the main structure 1 of the pipeline by setting the accommodating outer shell 201. The partition inner plate 202 is used to separate the internal space of the accommodating outer shell 201. The set pushing block 203 is used to push the damping medium. When an external impact occurs, the left half shell 301 and the right half shell 302 transfer the impact to the position of the pushing block 203 through the connecting plate 207, driving the pushing block 203 to move. The pushing block 203 pushes the damping medium to make it flow through the flow hole 204 to play a damping and buffering effect. After the impact is over, the reset spring 205 rebounds and drives the pushing block 203 to rebound.

[0049] like Figure 3 As shown, the interior of the housing 201 is filled with viscous oil, and the top and bottom of the inner wall of the partition inner plate 202 are bolted with limit rings 9. The surface of the limit ring 9 is used in conjunction with the push block 203. The viscous oil is set to be used as a damping medium, and the limit ring 9 is set to limit the position of the push block 203 to avoid the flow hole 204 being blocked due to its excessive displacement.

[0050] like Figure 5 As shown, the outer side of the super absorbent resin 6 is wrapped with a paper packaging bag 11, and a sealing pad 12 is provided on the side of the top of the left half shell 301 close to the right half shell 302 and the side of the top of the right half shell 302 close to the left half shell 301. The paper packaging bag 11 is provided to wrap the super absorbent resin 6. When it comes into contact with water, the water will penetrate the paper packaging bag 11 and contact the super absorbent resin 6, causing it to expand and open the paper packaging bag 11. The provided sealing pad 12 is used to improve the sealing effect and prevent water in the external environment from accidentally entering the interior of the protective component 3.

[0051] like Figure 9As shown in the figure, a buckle 7 is welded to the outside of the bottom of the left half shell 301, and a clamping block 8 is welded to the outside of the bottom of the right half shell 302. The surface of the clamping block 8 is clamped with the buckle 7. By setting the cooperation of the buckle 7 and the clamping block 8, when the left half shell 301 and the right half shell 302 are clamped outside the main pipeline structure 1, they can be fixed. During installation, the superabsorbent resin 6 can be first placed inside the receiving groove 5, and then clamped to complete the installation.

[0052] Brief description of the use process: By setting the protection component 3, when an impact occurs outside, it will hit the left half shell 301 and the right half shell 302. The left half shell 301 and the right half shell 302 are buffered by the force receiving component 2. The impact is transmitted to the position of the push block 203 through the connecting plate 207, driving the push block 203 to move. The push block 203 pushes the damping medium to flow through the flow holes 204 to achieve a buffering effect, protecting the main pipeline structure 1 and reducing damage to the protection component 3 at the same time.

[0053] Embodiment 2:

[0054] Reference Figure 1-8 , a high-strength steel wire mesh reinforced composite pipeline, including a main pipeline structure 1. A buffer component 4 is arranged on the inner wall of the main pipeline structure 1. The arranged buffer component 4 can be used to buffer the impact of the transportation medium inside the main pipeline structure 1.

[0055] As Figure 8 shown, the buffer component 4 includes a secondary receiving shell 401. A piston 402 is slidably connected to the inner wall of the secondary receiving shell 401. A compression spring 403 is bolted to the bottom of the piston 402. The bottom of the compression spring 403 is bolted to the secondary receiving shell 401. By setting the cooperation of the secondary receiving shell 401 and the piston 402, when water enters the main pipeline structure 1 and flows with high impact, the impact acts on the piston 402, and the piston 402 moves towards the position of the compression spring 403. Under the action of irregular impact and the continuous force applied by the compression spring 403, the piston 402 moves in the vertical direction, effectively eliminating the water hammer wave oscillation and avoiding excessive impact on the main pipeline structure 1.

[0056] As Figure 8 shown, a limit telescopic rod 10 is bolted to the bottom of the piston 402. The bottom of the limit telescopic rod 10 is bolted to the secondary receiving shell 401. By setting the limit telescopic rod 10, the moving position of the piston 402 can be limited to avoid rotation or liquid leakage.

[0057] Brief description of the usage process: By setting the buffer component 4, when the water supply is unstable or when the valve is opened or closed, the impact acts on the piston 402. The piston 402 moves towards the position of the compression spring 403. Under the action of irregular impacts and the continuous force exerted by the compression spring 403, the piston 402 moves in the vertical direction to reduce the impact, effectively protecting the main pipeline structure 1 and the water supply position, and improving the service life of the main pipeline structure 1.
