Description

Technical Field

[0001] The utility model relates to the field of pipeline structures, in particular to a high-strength impact-resistant plastic pipeline. Background Art

[0002] Water conservancy projects are used to control and allocate natural surface water and groundwater. Water is a valuable resource that is indispensable to human production and life, but its natural state does not fully meet human needs. Only by building water conservancy projects can we control water flow, prevent floods and waterlogging disasters, and regulate and distribute water to meet people's needs for water resources in life and production. Therefore, water conservancy projects need to use various plastic pipes to ensure the normal operation and use of the project;

[0003] Generally, plastic pipes have the effect of strengthening the structure. The support structure set on the outside of the pipe is not as strong as the support structure set inside the pipe. In water conservancy projects, water flows at high speed inside the pipe, but the support structure set inside the pipe has a greater impact on the flow rate of the liquid, increasing energy consumption.

[0004] Therefore, it is necessary to propose a high-strength impact-resistant plastic pipe to solve the above problems. Utility Model Content

[0005] The utility model aims to provide a high-strength impact-resistant plastic pipe to solve the problem that the supporting structure inside the pipe has a great influence on the flow velocity of the liquid and increases energy consumption.

[0006] To achieve the above object, the utility model provides the following technical solutions: a high-strength impact-resistant plastic pipe, comprising a pipe body, a vortex tube fixed inside the pipe body to accelerate the flow of liquid, and a plurality of arc-shaped plates for supporting the pipe body fixed at one end of the vortex tube;

[0007] The inner side of the vortex tube is provided with a front cone surface, and the front cone surface of the vortex tube is provided with a plurality of vortex grooves, and the plurality of vortex grooves are arranged in a ring array;

[0008] A plurality of support rods are fixedly provided at one end of the vortex tube, one side of the support rods is also fixed with one side of the corresponding connecting arc plate, a connecting inner tube is fixedly provided at one end of the vortex tube, and a reflux tube is fixedly provided at one end of the connecting inner tube.

[0009] Preferably, the arc-shaped plates are arranged in a circular array, two first support plates are fixedly provided at both ends of the support rod, one end of the first support plate is fixedly connected to the outer side of the corresponding arc-shaped plate, one end of the first support plate is fixedly provided with a second support plate, and one end of the second support plate is also fixedly connected to one end of the corresponding arc-shaped plate.

[0010] Preferably, a rear conical surface is provided on the inner side of the reflux tube.

[0011] Preferably, the arc-shaped plate and one end of the support rod are also fixedly connected to one end of the reflux pipe.

[0012] Preferably, the inner angles of the rear cone and the front cone are oppositely arranged.

[0013] Technical effects and advantages of the utility model:

[0014] 1. Through the setting of the vortex groove, when the water flows into the vortex tube, the liquid near the inner wall of the tube body will enter the vortex groove, so that the water flowing through the vortex groove advances in a vortex manner, and then the centrifugal force of the rotation is used to increase the flow speed of the liquid without affecting the flow of the liquid in the middle of the water flow;

[0015] 2. The vortex tube is used to shield the support rod and other support members, so that the influence of the support members can be reduced to a minimum when the tube body is supported from the inside, and the rear cone surface on the reflux tube is set to minimize the fluctuation of the liquid when the liquid passes through the support member;

[0016] 3. The inside of the tube body is supported from the outside by support rods and arc plates, the first support plate and the second support plate, and the contact area between the arc plate and the inner wall of the tube body is large, which can effectively increase the strength of the tube body and withstand higher impact forces. The first support plate and the second support plate form a plurality of triangular arrangements, thereby increasing the support strength. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] The utility model provides Figure 1 - Figure 4 The high-strength impact-resistant plastic pipe shown in the figure includes a pipe body 1, which is a plastic pipe and is a prior art, and will not be described in detail here. A vortex tube 2 is fixedly provided on the inner side of the pipe body 1 to accelerate the flow of liquid, and a front cone 8 is provided on the inner side of the vortex tube 2. A plurality of arc-shaped plates 4 for supporting the pipe body 1 are fixedly provided on one end of the vortex tube 2;

[0024] The vortex tube 2 has a plurality of vortex grooves 3 on its front cone surface 8. The vortex grooves 3 are arranged so that when the water flows into the vortex tube 2, the liquid near the inner wall of the tube body will enter the vortex grooves 3, so that the water flows through the vortex grooves 3 in a vortex manner. When the liquid rotates in the pipe, it will generate an outward centrifugal force, which will try to push the liquid to the pipe wall, thereby increasing the flow rate of the liquid area at the edge of the pipe. The depth of the vortex grooves 3 is shallow and will not affect the flow of the liquid in the center of the pipe. The plurality of vortex grooves 3 are arranged in a ring array to ensure the uniformity and stability of the liquid when it rotates.

[0025] A plurality of support rods 5 are fixedly provided at one end of the vortex tube 2, and one side of the support rods 5 is also fixed to the corresponding side of the connecting arc plate 4.

A connecting inner tube 6 is fixedly provided at one end of the vortex tube 2, and a reflux tube 7 is fixedly provided at one end of the connecting inner tube 6. A rear cone 9 is provided on the inner side of the reflux tube 7.

[0026] The arc plates 4 are arranged in a ring array to ensure the balance of the supporting force inside the tube body 1. Two first support plates 10 are fixedly provided at both ends of the support rod 5. The support rod 5 and the first support plate 10 are arranged in a triangle. One end of the first support plate 10 is fixedly connected to the outer side of the corresponding arc plate 4. A second support plate 11 is fixedly provided at one end of the first support plate 10. One end of the second support plate 11 is also fixedly connected to one end of the corresponding arc plate 4. The inside of the tube body 1 is supported from the outside by the support rod 5 and the arc plate 4, the first support plate 10 and the second support plate 11. The contact area between the arc plate 4 and the inner wall of the tube body 1 is large, which can effectively increase the strength of the tube body 1 and can withstand higher impact forces. The first support plate 10 and the second support plate 11 form a plurality of triangular arrangements, thereby increasing the supporting strength.

[0027] The arc-shaped plate 4 and one end of the support rod 5 are also fixedly connected to one end of the reflux pipe 7 to ensure that the overall components are integrated.

[0028] The inner angles of the rear cone surface 9 and the front cone surface 8 are opposite to each other. The liquid enters the vortex tube 2 from the front cone surface 8 and is discharged from the rear cone surface 9 of the reflux tube 7.
