Abstract

Technical Field
[0001] The utility model relates to the technical field of spiral steel pipes, in particular to an anti-corrosion plastic-coated spiral steel pipe structure. Background Art
[0002] Spiral steel pipe is a steel pipe whose manufacturing process involves bending hot-rolled strip steel or cold-rolled strip steel into a spiral shape and then welding it. This steel pipe is usually used to transport liquids, gases, sediments, steam, etc. Since its production process is different from traditional straight seam welded pipes, spiral steel pipes are also called spiral welded pipes in some occasions.
[0003] When using spiral steel pipes to transport water, bolts are usually used to connect the spiral steel pipes together. However, leakage may occur at the joints of the spiral steel pipes. When the amount of leaked water is large, the leakage can be discovered by changes in water pressure. However, if the amount of leaked water is small, the water pressure in the pipe may not change significantly, making it difficult to discover the leakage in a short period of time, resulting in a waste of water resources.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
[0023] like Figures 1 to 5 As shown, a first flange 2 and a second flange 3 are respectively installed at both ends of the pipe body 1, and the first flange 2 and the second flange 3 are used for connecting the pipe body 1. A first annular groove 4 is provided on the outer surface of the first flange 2, and a first sealing ring 5 is arranged inside the first annular groove 4, and the first sealing ring 5 plays a sealing role at the connection.
[0024] A second annular groove 6 is provided on the outer surface of the first flange 2, and the second annular groove 6 is coaxially arranged with the first annular groove 4, and the second annular groove 6 is arranged on the outer side of the first annular groove 4, a vertical pole 7 is vertically installed inside the second annular groove 6, a floating ball 8 is sleeved on the outer surface of the vertical pole 7, a touch switch 10 is installed inside the second annular groove 6 on the upper side of the vertical pole 7, an alarm 9 is installed on the outer surface of the first flange 2 facing away from the second annular groove 6, the alarm 9 is electrically connected to the touch switch 10, when water seeps into the second annular groove 6, the floating ball 8 can float, the vertical pole 7 limits the floating ball 8, so that the floating ball 8 can float vertically and contact with the touch switch 10, and then an alarm signal is sent out through the alarm 9.
[0025] A third annular groove 16 is provided on the outer surface of the first flange 2, and the third annular groove 16 is coaxially arranged with the second annular groove 6, and the third annular groove 16 is arranged on the outer side of the second annular groove 6, and a second sealing ring 17 is provided inside the third annular groove 16. By providing the second sealing ring 17, a double sealing effect can be achieved. When the first annular groove 4 leaks, water seeps into the second annular groove 6 and triggers the alarm 9. The second sealing ring 17 can prevent the water from continuing to leak to the outside, thereby reducing the waste of water resources and enabling people to detect the leakage.
[0026] An inner ring 11 is arranged inside the tube body 1, and the inner ring 11 is arranged coaxially with the tube body 1. Eight support rods 12 are installed in a circumferential array on the outer surface of the inner ring 11. Through the arrangement of the inner ring 11 and the support rods 12, the interior of the tube body 1 can be supported, the compression resistance of the tube body 1 is improved, the possibility of deformation and damage of the tube body 1 under external force impact is reduced, and the service life and safety of the tube body 1 are improved. Eight slide rails 13 are evenly installed on the inner wall of the tube body 1, and sliders 14 are installed at the ends of the eight support rods 12. The sliders 14 are slidably installed inside the slide rails 13, and screw holes are opened on the outer surfaces of the sliders 14 on both sides of the length direction. Screws 15 are installed on the outer surfaces of the slide rails 13 on both sides of the length direction, and the screws 15 are adapted to the screw holes. When installing the inner ring 11 and the support rod 12, it is only necessary to insert the slider 14 at the end of the support rod 12 into the slide rail 13, and then screw the screws 15 into the screw holes on the slider 14. The limiting effect of the slide rail 13 on the slider 14 and the fixed cooperation of the screws 15 and the screw holes can ensure the stability of the inner ring 11 and the support rod 12 during use. When the inner ring 11 and the support rod 12 need to be removed, it is only necessary to unscrew the screws 15, and then pull the slider 14 out of the slide rail 13, so as to achieve the purpose of reuse.
[0027] The outer surface of the pipe body 1 is provided with an anti-corrosion layer 18, which is made of polyvinyl chloride. The anti-corrosion performance of the pipe body 1 can be improved by providing the anti-corrosion layer 18, thereby improving its service life.

[0029] When in use, the first sealing ring 5 and the second sealing ring 17 are placed in the first annular groove 4 and the third annular groove 16 respectively, and then the first flange 2 of one pipe body 1 and the second flange 3 of another pipe body 1 are docked and connected together by bolts. The first sealing ring 5 and the second sealing ring 17 can play a double sealing role. When a small amount of water leaks at the first annular groove 4, water will penetrate into the second annular groove 6 through the first annular groove 4. As the water level inside the second annular groove 6 rises, the float 8 will float up and contact the touch switch 10 under the limiting effect of the vertical rod 7, and then an alarm signal can be sent through the alarm 9, so that when a small amount of water leaks, people can find and deal with it in time, and due to the sealing effect of the second sealing ring 17, water can be prevented from continuing to leak to the outside, thereby reducing the waste of water resources, and during the use of the pipe body 1, the inner ring 11 and the support rod 12 can support the inside of the pipe body 1, thereby improving the compressive strength of the pipe body 1, reducing the possibility of deformation and damage of the pipe body 1 under the impact of external force, and improving the service life and safety of the pipe body 1.
