Description

Technical Field

[0001] This utility model relates to the field of spiral corrugated pipe technology, specifically a composite reinforced spiral corrugated pipe. Background Technology

[0002] Spiral corrugated pipes are widely used as a key pipe material in municipal engineering, building construction and various infrastructure projects, especially in drainage and sewage treatment. Compared with traditional concrete pipes and metal pipes, they have significant advantages. Spiral corrugated pipes have lower costs and excellent corrosion resistance, making them an ideal choice for many engineering projects. Composite reinforced spiral corrugated pipe is a new type of pipe developed to address the performance shortcomings of traditional spiral corrugated pipes under complex working conditions. Through the deep integration of structural innovation and material composite technology, it has achieved a leapfrog improvement in comprehensive performance. The inner layer is usually made of corrosion-resistant modified material, which can resist the erosion of media such as acids, alkalis and microorganisms, and ensure the cleanliness of the transported media. The middle layer introduces a high-strength reinforcement (such as glass fiber, carbon fiber or metal mesh skeleton), which is tightly combined with the substrate through a spiral winding process to form a three-dimensional support structure. This can not only evenly distribute the external load, but also avoid the problem of uneven local strength caused by traditional exposed reinforcing ribs. The outer layer is made of a high-polymer material with excellent weather resistance, which can withstand extreme environments such as underground moisture and high temperature exposure, and extend the service life of the pipeline. Currently, when installing and connecting composite reinforced spiral corrugated pipes, bushing connections are generally used. Since bushing connections are installed by snap-fit, they are convenient to connect and disassemble, thus achieving a quick connection effect. However, during drainage, when the water pressure inside the pipe is high, the strong water pressure will impact the pipe connection, causing leakage or even detachment at the corrugated pipe connection, which will affect the connection between the corrugated pipes and thus prevent normal drainage.

[0003] Therefore, a composite reinforced spiral bellows is proposed to address the above problems. Utility Model Content

[0015] 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.

[0016] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0017] Please see Figures 1-6 This utility model provides a technical solution: A composite reinforced spiral corrugated pipe includes a corrugated pipe body 1, with a snap ring 2 and a bushing 3 fixedly connected to both ends of the corrugated pipe body 1, and a stabilizing mechanism 4 provided inside the bushing 3. The stabilizing mechanism 4 includes a mounting groove 41, a rubber clamping plate 42 fixedly connected to the outer side of the snap ring 2, a rubber clamping plate 43 provided inside the snap ring 2, a movable tube 44 fixedly connected to the outer side of the bushing tube 3, a screw 45 rotatably connected inside the movable tube 44, a rotating ring 46 fixedly connected to the outer side of the screw 45, and a threaded hole 47 opened in the side wall of the snap ring 2.

[0018] It should be noted that: the snap ring 2 is compatible with the mounting groove 41 inside the bushing tube 3, the rubber clamp 42 is T-shaped, the number of rubber clamps 42 and rubber clips 43 is the same, and the rubber clamps 42 and rubber clips 43 are compatible with each other, the movable tubes 44 are evenly distributed on the outside of the bushing tube 3, and the movable tubes 44 are in a connected state with the mounting groove 41.

[0019] Furthermore: the number of movable tubes 44 and rubber clamps 43 is the same, and the movable tubes 44 and rubber clamps 43 are distributed in a cross pattern. The threaded holes 47 are evenly distributed in the side wall of the snap ring 2, and the threaded holes 47 and rubber clamps 42 are distributed in a cross pattern. The screw 45 is adapted to the threaded holes 47, and the bottom of the screw 45 is engaged with the inside of the threaded holes 47.

[0020] As a further implementation of this solution, the corrugated pipe body 1 and the snap rings 2 and bushings 3 at both ends are integrally formed by hot-melt butt welding or injection molding, avoiding stress concentration caused by traditional welding connections. The spiral corrugated structure of the body not only improves the ring stiffness, but the size of its crests and troughs is also optimized to form a gradient transition with the wall thickness of the snap ring 2, ensuring that the load at the connection point can be evenly transferred to the pipe body and reducing local deformation at the interface. The outer wall of the snap ring 2 is not a smooth design, but has fine raised textures that match the inner wall of the mounting groove 41. When docking, the radial friction is further enhanced by the meshing of the textures. Together with the T-shaped rubber clamp 42, it forms a dual positioning of "mechanical locking + friction anti-slip". The threaded hole 47 on its side wall adopts a countersunk design. When the screw 45 is fully screwed in, the nut can be embedded in the hole to avoid interference with the inner wall of the bushing 3 and ensure a tight connection.

[0021] Meanwhile, the length of the bushing 3 is slightly greater than the thickness of the snap ring 2, leaving a buffer space for the mounting groove 41, allowing for an angular deviation of ±2° during the docking process, thus improving the construction tolerance. The outer movable tube 44 is vertically welded to the bushing 3, and its internal diameter is precisely matched with the diameter of the screw 45, ensuring that the screw 45 can rotate flexibly and avoiding uneven locking force caused by shaking through gap control. Although the number of rubber clamps 42 and rubber clips 43 is the same, they are arranged in an alternating manner. The rubber clamps 42 are evenly distributed radially along the outer side of the snap ring 2, while the rubber clips 43 are located at the corresponding gaps on the inner side of the snap ring 2. This design allows the two to form a balanced state of "external tension and internal pressure" when under force: the rubber clamps 42 open outward to press against the mounting groove 41, and the rubber clips 43 contract inward to clamp the snap ring 2, jointly enhancing the overall rigidity of the interface.

[0022] Workflow: When two corrugated pipe sections are connected, initial positioning is achieved first through the matching structure of the snap ring 2 and the bushing 3. The snap ring 2 at one end of the corrugated pipe body 1 is inserted into the bushing 3 of the other pipe section. The outer wall of the snap ring 2 fits snugly with the mounting groove 41 inside the bushing 3. Radial limiting is achieved by utilizing the dimensional tolerances of the two, thereby preventing lateral displacement during the docking process. At the same time, the T-shaped rubber clamp 42 on the outside of the snap ring 2 will fit into the corresponding groove on the inner wall of the mounting groove 41, forming the first mechanical lock. The rubber clamp 42 compensates for processing errors by its own elastic deformation, and at the same time, the lateral support force of the T-shaped structure prevents the interface from axially falling off. As the snap ring 2 is fully embedded in the mounting groove 41, the interaction between the rubber clamp 42 and the rubber clip 43 initiates a secondary seal. The number of rubber clips 43 inside the snap ring 2 is the same as that of the rubber clamp 42, and they are matched one by one. Under the action of the mating pressure, the rubber clip 43 applies radial extrusion force to the rubber clamp 42, causing the contact surface of the two to undergo elastic deformation, thereby filling the interface gap. Since the rubber clamp 42 adopts a T-shaped design, its lateral flange forms a surface contact with the rubber clip 43. Combined with the high sealing performance of the rubber material itself, they jointly construct an annular sealing strip, effectively blocking the leakage path of the medium. After sealing is completed, rigid fixation is achieved through the meshing transmission of screw 45 and threaded hole 47. The movable tube 44 on the outside of the bushing tube 3 is connected to the mounting groove 41. When the screw 45 inside the movable tube 44 is rotated, the outer rotating ring 46 provides the operating fulcrum, causing the screw 45 to advance axially. Its bottom can be precisely screwed into the threaded hole 47 on the side wall of the snap ring 2. Since the movable tube 44 and the rubber clamp 43 are intersected, and the threaded hole 47 and the rubber clamp 42 are intersected, the locking force of the screw 45 can be evenly transmitted to different areas of the snap ring 2, avoiding local stress concentration. As the screw 45 is continuously tightened, the gap between the snap ring 2 and the bushing tube 3 is gradually eliminated, forming a rigid connection, further compressing the rubber sealing assembly, and improving the sealing effect. During long-term use, multiple components work together to cope with changes in operating conditions. When the pipeline is subjected to external forces such as soil settlement and temperature changes, the elastic deformation of the rubber clamp 42 and rubber clip 43 can absorb some of the stress and prevent the rigid connection from breaking. The meshing structure of the screw 45 and the threaded hole 47 provides continuous locking force to prevent the interface from loosening. The cross-distributed movable pipe 44 and the sealing components form a three-dimensional force network to ensure that the stress can be evenly distributed and maintain the stability of the overall pipeline structure.

[0023] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
