DETAILED DESCRIPTION

[0021] 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.

[0022] This utility model provides, for example Figures 1-4 The illustrated pressure-resistant PVC pipe includes a first pipe 1, a movable plate 8, and a pressure-resistant mechanism. A connecting sleeve 3 is movably sleeved at one end of the outer wall of the first pipe 1, and a second pipe 2 is movably sleeved at the other end of the connecting sleeve 3. The first pipe 1 and the second pipe 2 are used to transport water. A slide rail 10 is fixedly connected to the inner cavity of the connecting sleeve 3, and a slide rod 11 is slidably connected to the inner wall of the slide rail 10. The movable plate 8 is fixedly connected to the side of the slide rod 11 away from the connecting sleeve 3. An elastic mechanism is fixedly installed on the inner wall of the slide rail 10, and the slide rod 11 is slidably installed on the outer wall of the elastic mechanism. The pressure-resistant mechanism is located outside the first pipe 1. The pressure-resistant mechanism is used to prevent deformation of the first pipe 1. During the use of the pipe, the first pipe 1 is buried underground, and water flows through the connecting sleeve 3 to the second pipe 2. When water hammer is formed, the water flows through the first pipe 1 and impacts the connecting sleeve 3. The water hammer impacts the moving plate 8, and the moving plate 8 drives the sliding rod 11 to move. The sliding rod 11 squeezes the elastic mechanism, and the elastic mechanism reduces the impact force of the water hammer and avoids the connecting sleeve 3 being directly impacted by the water hammer. After the water hammer impact ends, the elastic mechanism drives the sliding rod 11 to reset. This process is repeated to prevent the pipe from cracking or developing cracks after long-term use.

[0023] On one hand, there are multiple slide rails 10 arranged at intervals. The elastic mechanism includes a circular rod 13, which is fixedly connected to the inner cavity of the connecting sleeve 3. The slide rod 11 is slidably sleeved on the outer wall of the circular rod 13. A spring 12 is fixedly connected between the connecting sleeve 3 and the slide rod 11. The side of the slide rod 11 away from the connecting sleeve 3 is fixedly connected to the outer wall of the moving plate 8. When the moving plate 8 drives the slide rod 11 to move, the slide rod 11 compresses the spring 12, and the spring 12 achieves the purpose of buffering the water hammer pressure.

[0024] On the other hand, the pressure-resistant mechanism consists of multiple sets arranged horizontally at intervals. The pressure-resistant mechanism includes a base plate 15, which is located below the first pipe 1. A second connecting rod 16 is fixedly connected to the top of the base plate 15. A top plate 4 is movably sleeved on the top of the second connecting rod 16. Anchor nails 17 are movably connected to the top of the base plate 15. When installing the first pipe 1, the base plate 15 is first fixed using the anchor nails 17. Then, the first pipe 1 is installed between the second connecting rods 16. Finally, the worker installs the top plate 4 on the top of the second connecting rods 16. Multiple top plates 4 work together to support the soil layer on top of the first pipe 1, preventing changes in the underground environment from causing deformation of the first pipe 1.

[0025] Preferably, the first pipeline 1 and the second pipeline 2 are externally provided with a protection mechanism for protecting the outer walls of the first pipeline 1 and the second pipeline 2, the protection mechanism comprising two anticorrosion sleeves 14 fixedly sleeved on the outer walls of the first pipeline 1 and the second pipeline 2 respectively, a fixed plate 9 fixedly connected to the inner cavity of the connecting sleeve 3 and arranged between the connecting sleeve 3 and the moving plate 8, a buffer pad 5 fixedly connected to the side of the fixed plate 9 close to the moving plate 8, the anticorrosion sleeves 14 can protect the first pipeline 1 from being corroded on the outside of the ground, at the same time, the anticorrosion sleeves 14 protect the second pipeline 2 from being irradiated by ultraviolet rays to prevent the second pipeline 2 from cracking, and the buffer pad 5 prevents the moving plate 8 from moving too fast and the slide rod 11 from being damaged.

[0026] In addition, the moving plate 8 is externally provided with a flow splitting mechanism comprising a flow splitting plate 7, the moving plate 8 is fixedly connected with a first connecting rod 6 on the side away from the fixed plate 9, and the flow splitting plate 7 is fixedly connected to the side of the first connecting rod 6 away from the moving plate 8, the flow splitting plate 7 is arranged in a conical shape, and when the water hammer impacts the flow splitting plate 7, the flow splitting plate 7 splits the water flow to both sides to reduce the water hammer impact force.

[0027] Specifically, when the water flow forms a water hammer, the water hammer impacts the flow splitting plate 7, the flow splitting plate 7 splits the water flow to both sides to reduce the water hammer impact force, the water hammer impacts the moving plate 8, the moving plate 8 drives the slide rod 11 to move, the slide rod 11 presses the spring 12, and the spring 12 achieves the purpose of buffering the water hammer pressure, after the water hammer impact ends, the spring 12 drives the slide rod 11 to reset to prevent the pipeline from being broken or cracked.

[0028] Finally, it should be noted that the above description is only a preferred embodiment of the present application and is not intended to limit the present application, although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions recorded in the foregoing embodiments or make equivalent replacements for some technical features, and any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application shall be included in the protection scope of the present application.
