Description

Technical Field

[0001] The utility model relates to the technical field of polyethylene spiral corrugated pipes, and more specifically, to a polyethylene spiral corrugated pipe with an adjustable liquid inlet. Background Art

[0002] Polyethylene spiral corrugated pipe is a kind of pipe made by special process. Its main feature is that it uses high-density polyethylene as the matrix, combined with steel strip coated with adhesive resin on the surface to form a corrugated structure as the main supporting structure, and is wrapped and compounded with polyethylene material to form a double-wall spiral corrugated pipe as a whole.

[0003] The existing publication number CN107448694A discloses an internal rib reinforced polyethylene spiral corrugated pipe, which specifically discloses a pipe body formed by spirally winding and bonding strip-shaped plates. The strip-shaped plates include a base plate and a closed cavity provided in the middle of the base plate. The base plate and the closed cavity are integrally formed. Reinforcement ribs are provided in the closed cavity. When the strip-shaped plates are spirally wound, the contact surfaces of the base plate form a horizontal bonding surface. The present invention has a simple structure and a reasonable design. The closed cavity and the base plate are integrally formed, so that the reinforcement rib structure in the closed cavity is stable and not easily skewed or deformed, thereby improving the pressure bearing capacity and ring stiffness of the corrugated pipe. The left and right sides of the base plate are inclined surfaces with the same inclination direction. Bonding is performed through the inclined surfaces. The bonding technology and process requirements are not high, which is conducive to processing and molding, reduces the scrap rate, and improves production efficiency.

[0004] The position of the liquid inlet of existing polyethylene spiral corrugated pipes cannot be adjusted. This fixed position means that the direction and speed of the fluid entering the pipe are also relatively fixed. This can lead to uneven fluid distribution within the pipe. Especially in long pipes or those with multiple branches, some areas may experience slow or stagnant flow, affecting the overall fluid transmission efficiency. To address this issue, we propose a polyethylene spiral corrugated pipe with an adjustable liquid inlet. Utility Model Content

[0005] In order to overcome the deficiencies of the prior art, the utility model provides a polyethylene spiral corrugated pipe with an adjustable liquid inlet, which has the advantage that the position of the liquid inlet can be adjusted.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solution: a polyethylene spiral corrugated pipe with an adjustable liquid inlet, comprising a bracket, two movable seats arranged at intervals are arranged in the bracket, and limiting holes are provided on the movable seats. A plurality of equidistantly distributed perforations are provided on one side of the bracket, and the perforations all pass through the bracket.

[0007] The cam is provided with a plurality of threaded holes, and the two ends of the cam are fixedly mounted on the movable seats at both sides. The cam passes through the movable seat, and the ends of the cam are fixedly mounted with an annular piece, and the annular piece has a plurality of threaded mounting holes. The bracket is fixedly mounted with two guide rods arranged at intervals, and the guide rods pass through the movable seat. The movable seat is provided with a limiting mechanism, and the limiting mechanism is used to fix the position of the movable seat. The upper end of the bracket is provided with a top plate, and the top plate has a plurality of threaded mounting holes distributed in a circumferential array. A connecting shaft is rotatably mounted at the center of the bottom of the top plate, and the lower end of the connecting shaft is fixedly mounted on the bracket, and a gear ring is fixedly mounted on the connecting shaft. A motor is fixedly mounted on the bottom of the top plate, and a driving wheel is fixedly mounted on the output shaft end of the motor, and the driving wheel meshes with the gear ring.

[0008] As a preferred technical solution of the present invention, sealing gaskets are provided on the annular sheets.

[0009] As an optimal technical solution of the present utility model, the limiting mechanism includes a support plate, which is fixedly mounted on the bracket. A limiting rod passes through the support plate, a disc is fixedly mounted on one end of the limiting rod, and a spring is sleeved on the limiting rod. The two ends of the spring are respectively fixedly connected to the support plate and the disc.

[0010] As a preferred technical solution of the present invention, an annular slide is fixedly installed on the bottom of the top plate, and sliders are fixedly installed on both ends of the bracket, and the sliders are slidably arranged in the annular slide.

[0011] As a preferred technical solution of the present invention, the surface of the slider is polished.

[0012] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0013] The utility model uses a motor to drive the driving wheel to rotate, which in turn drives the ring gear to rotate. The ring gear and the connecting shaft rotate synchronously, thereby driving the bracket to rotate around the connecting shaft. The bellows in the bracket can be rotated to different directions, thereby adjusting the orientation of the bellows to adapt to different usage environments. By moving the movable seat to adjust the horizontal position of the movable seat, the bellows on the movable seat can be moved to different positions along the guide rod, thereby adjusting the horizontal position of the bellows. The adjustable liquid inlet position allows the piping system to flexibly respond to different working conditions and needs. When it is necessary to adjust the fluid flow or direction, it is only necessary to simply adjust the liquid inlet position, without replacing the entire piping system or performing complex renovation projects.

DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] like Figures 1 to 5 As shown, the utility model provides a polyethylene spiral corrugated pipe with an adjustable liquid inlet, including a bracket 1, two movable seats 2 arranged at intervals are arranged in the bracket 1, and limiting holes 3 are provided on the movable seats 2. A plurality of equally distributed through holes 4 are provided on one side of the bracket 1, and the through holes 4 all pass through the bracket 1. The bracket 1 further includes a bellows 5, the ends of which are fixedly mounted on the movable seats 2 on both sides. The ends of the bellows 5 pass through the movable seats 2. An annular piece 6 is fixedly mounted on each end of the bellows 5, and the annular piece 6 has multiple threaded mounting holes. Two guide rods 7 are fixedly mounted in the bracket 1 at intervals. The guide rods 7 pass through the movable seats 2. The movable seats 2 are each provided with a limit mechanism for fixing the position of the movable seats 2. A top plate 8 is provided at the upper end of the bracket 1. The top plate 8 has multiple threaded mounting holes distributed in a circumferential array. A connecting shaft 9 is rotatably mounted at the center of the bottom of the top plate 8. The lower end of the connecting shaft 9 is fixedly mounted on the bracket 1. A gear ring 10 is fixedly mounted on the connecting shaft 9. A motor 11 is fixedly mounted on the bottom of the top plate 8. A driving wheel 12 is fixedly mounted on the output shaft end of the motor 11. The driving wheel 12 meshes with the gear ring 10. A sealing gasket is provided on each annular piece 6.

[0022] Among them, such as Figure 3 and Figure 4As shown, the limiting mechanism includes a support plate 13, which is fixedly mounted on the bracket 1. A limiting rod 16 extends through the support plate 13. A disc 14 is fixedly mounted on one end of the limiting rod 16. A spring 15 is sleeved on the limiting rod 16, and the ends of the spring 15 are respectively fixedly connected to the support plate 13 and the disc 14. An annular slide 17 is fixedly mounted on the bottom of the top plate 8. Sliders 18 are fixedly mounted on both ends of the bracket 1, and the slides 18 are slidably mounted in the annular slide 17. The surfaces of the slides 18 are polished.

[0023] The working principle and use process of this utility model:

[0024] By mounting the top plate 8 on the external mounting surface, the motor 11 drives the driving wheel 12 to rotate, which in turn drives the ring gear 10. The ring gear 10 and the connecting shaft 9 rotate synchronously, thereby driving the bracket 1 to rotate about the connecting shaft 9. This allows the bellows 5 within the bracket 1 to rotate to different directions, thereby adjusting the orientation of the bellows 5 to suit different operating environments. By pulling the disc 14 to move the end of the limiting rod 16 out of the limiting hole 3, the movable seat 2 can be freely moved, thereby adjusting its horizontal position. The bellows 5 on the movable seat 2 can be moved to different positions along the guide rod 7, thereby adjusting the horizontal position of the bellows 5. The end of the limiting rod 16 then passes through the through-hole 4 and into the limiting hole 3, thereby fixing the position of the movable seat 2 and, in turn, maintaining the position of the liquid inlet of the bellows 5. This adjustable liquid inlet position allows the piping system to flexibly adapt to different operating conditions and requirements. For example, when the flow rate or direction of the fluid needs to be adjusted, simply adjust the position of the liquid inlet, without having to replace the entire piping system or undergo complex renovations.
