Description

Technical Field

[0001] The utility model relates to the technical field of polyethylene pipes, in particular to a novel high-density hollow wall plastic-steel wound polyethylene pipe. Background Art

[0002] HDPE plastic-steel wrapped pipe, also known as polyethylene plastic-steel wrapped pipe, is made of steel-plastic composite special-shaped strips through spiral winding and welding. Its inner wall is smooth and flat. This type of pipe has the advantages of corrosion resistance, light weight, easy installation, large flow rate and long service life. The traditional HDPE plastic-steel wrapped pipe is mainly made of a smooth inner wall made of polyethylene material and a steel strip spirally wrapped with the inner wall. The ring stiffness of the pipe is relatively high.

[0003] However, the drainage pipe uses less material and has a thinner wall, resulting in poor thermal insulation effect. It is easy to freeze when used in winter, which reduces the drainage effect. Utility Model Content

[0004] The purpose of the utility model is to solve the following shortcomings in the prior art, but the drainage pipe uses less material and has a thinner wall, resulting in poor thermal insulation effect. It is easy to freeze when used in winter, which reduces the drainage effect. A new type of high-density hollow wall plastic steel wrapped polyethylene pipe is proposed.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A novel high-density hollow wall plastic steel wrapped polyethylene pipe, comprising a pipe body and a shell, wherein the shell is fixedly connected to the side wall of the pipe body;

[0007] An adjustment mechanism is provided in the shell, and the adjustment mechanism includes a U-shaped frame, an airbag, a push plate, a push rod, and a triangular block. A plurality of U-shaped frames are fixedly connected to the inner side wall of the shell in a linear array, the airbag is fixedly connected to the inner side wall of the shell, the push plate is slidably connected to the inner side wall of the U-shaped frame, the push plate is slidably connected to the airbag, the push rod is fixedly connected to the lower end surface of the push plate, the push rod is slidably connected to the U-shaped frame, the triangular block is fixedly connected to the lower end surface of the push rod, and the triangular block is slidably connected to the shell.

[0009] Preferably, two groups of limit blocks are fixedly connected to both ends of the inner side wall of the tube body, the number of limit blocks in each group is two, and a limit rod is fixedly connected between the two limit blocks.

[0010] Preferably, a circular ring is slidably connected to the outer surface of the limiting rod, and a magnetic block is fixedly connected to the inner wall of the circular ring.

[0011] Preferably, the outer surface of the tube body is spirally fixedly connected with multiple plastic steel tubes, the multiple plastic steel tubes are fixedly connected to the shell, an air outlet pipe is fixedly connected between the airbag and the shell, the airbag is fixedly connected with an air inlet pipe, and both the air inlet pipe and the air outlet pipe are provided with a one-way valve.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] The circular motion is driven by water flow, so that the magnetic block drives the magnetic triangle plate to move. The magnetic triangle plate squeezes the triangle block, so that the push plate continuously squeezes the airbag, thereby continuously discharging the air in the shell and the hollow plastic steel pipe, forming a near-vacuum environment outside the pipe body, reducing the heat exchange between the pipe and the ground, making it difficult for the pipe to freeze, and ensuring the drainage effect.

[0015] The circular ring is driven by water flow to move, and the circular ring scrapes the inner wall of the pipe, scraping off slightly frozen particles and impurities, reducing condensation nuclei, avoiding pipe blockage, making it more difficult for water to freeze, and the magnetic block drives the magnetic triangle plate to move. The magnetic triangle plate squeezes the triangle block, and multiple triangle blocks continuously hit the pipe, breaking up slightly frozen particles, avoiding their tendency to freeze and ensuring the drainage effect.

DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0022] The terms such as "upper", "lower", "left", "right", "middle" and "one" cited in the present utility model are only for the convenience of description and are not used to limit the scope of application of the present utility model. Changes or adjustments in their relative relationships shall be regarded as the scope of application of the present utility model without substantially changing the technical content.

[0023] Reference Figure 1-Figure 4 A new type of high-density hollow wall plastic steel wrapped polyethylene pipe includes a pipe body 1 and a shell 2, and the shell 2 is fixedly connected to the side wall of the pipe body 1.

[0024] An adjusting mechanism is provided in the shell 2, and the adjusting mechanism includes a U-shaped frame 3, an airbag 4, a push plate 5, a push rod 6, and a triangular block 7. A plurality of U-shaped frames 3 are fixedly connected to the inner side wall of the shell 2 in a linear array, the airbag 4 is fixedly connected to the inner side wall of the shell 2, the push plate 5 is slidably connected to the inner side wall of the U-shaped frame 3, an impact spring 17 is fixedly connected between the push plate 5 and the U-shaped frame 3, the push plate 5 is slidably connected to the airbag 4, the push rod 6 is fixedly connected to the lower end surface of the push plate 5, the push rod 6 is slidably connected to the U-shaped frame 3, the triangular block 7 is fixedly connected to the lower end surface of the push rod 6, and the triangular block 7 is slidably connected to the shell 2. The main body of the mechanism is made of lightweight material and can be driven with relatively small force.

[0025] The adjustment mechanism further includes a fixing rod 8 and a magnetic triangular plate 9. The two fixing rods 8 are respectively fixedly connected to the inner side wall of the housing 2, and the magnetic triangular plate 9 is slidably connected to the fixing rods 8.

[0026] Two groups of limit blocks 10 are fixedly connected to the two ends of the inner wall of the tube body 1, and the number of limit blocks 10 in each group is two. A limit rod 11 is fixedly connected between the two limit blocks 10, and a circular ring 12 is slidably connected to the outer surface of the limit rod 11. The surface of the limit rod 11 is very smooth, and the friction between the limit rod 11 and the circular ring 12 is very small. The circular ring 12 is narrow and will not hinder the flow of water. A continuous water flow can drive the circular ring 12 to move. A reset spring 18 is fixedly connected between the circular ring 12 and the limit block 10, and a magnetic block 13 is fixedly connected to the inner wall of the circular ring 12.

[0027] The outer surface of the tube body 1 is spirally fixedly connected with multiple plastic steel tubes 14, the interior of the plastic steel tubes 14 is hollow, and the multiple plastic steel tubes 14 are fixedly connected to the shell 2. An outlet pipe 15 is fixedly connected between the airbag 4 and the shell 2, and an inlet pipe 16 is fixedly connected to the airbag 4. Both the inlet pipe 16 and the outlet pipe 15 are provided with a one-way valve. The flow direction of the one-way valve in the inlet pipe 16 is from the shell 2 to the airbag 4, and the flow direction of the one-way valve in the outlet pipe 15 is from the airbag 4 to the outside.

[0028] In the utility model, when there is a continuous water flow during use, ice will not form in the pipe. When the water flow is intermittent, a large continuous water flow will drive the ring 12 to move and compress the reset spring 18. The ring 12 scrapes the inner wall of the pipe body 1 to remove impurities on the inner wall of the pipe body 1, reduce condensation nuclei, make it more difficult for water to freeze, and scrape off slightly condensed ice particles to avoid their tendency to freeze.

[0029] The movement of the ring 12 drives the magnetic block 13 to move, and the magnetic block 13 attracts the magnetic triangular plate 9 to drive it to move. When the magnetic triangular plate 9 contacts the triangular block 7, it squeezes the triangular block 7. The triangular block 7 drives the push rod 6 to move upward and compresses the impact spring 17. The push rod 6 drives the push plate 5 to squeeze the airbag 4. The airbag 4 is squeezed and the inside is positively pressurized. Under the action of pressure, the worry valve in the air inlet pipe 16 is closed, and the one-way valve in the air outlet pipe 15 is opened. The gas in the airbag 4 is discharged to the outside along the air outlet pipe 15. When the magnetic triangular plate 9 falls off the triangular block 7, under the elastic force of the impact spring 17, the triangular block 7 is reset, and the triangular block 7 hits the tube body 1, causing the tube body 1 to vibrate, so that small particles of magazines fall off from the tube body 1, and the slightly frozen particles are broken. To prevent the air bag 4 from breaking, the push rod 6 and the push plate 5 are reset under the action of the triangular block 7, and the push plate 5 no longer squeezes the air bag 4. The air bag 4 recovers under its own elasticity, and the inside of the air bag 4 is under negative pressure. Under the action of pressure, the one-way valve in the air inlet pipe 16 is opened, and the one-way valve in the air outlet pipe 15 is closed. The air in the shell 2 and the hollow plastic-steel tube 14 enters the air bag 4 along the air inlet pipe 16. As the air in the shell 2 and the hollow plastic-steel tube 14 is continuously discharged, the inside is close to vacuum. At this time, the air bag 4 becomes shriveled and no longer resets, and will not contact the push plate 5 until air penetrates into the shell 2. The shell 2 and the plastic-steel tube 14, which are close to vacuum, isolate themselves from the heat exchange with the low-temperature ground, so that it is not easy to freeze when the water flow is not continuous.

[0030] In the present invention, unless otherwise clearly specified or limited, the terms "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense.

[0031] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
