Description

Technical Field

[0001] This utility model relates to the field of water supply and drainage pipeline technology, and in particular to an impact-resistant water supply and drainage pipeline. Background Technology

[0002] Water supply and drainage engineering is an engineering system that provides water for residents and industrial enterprises and discharges wastewater. It plays a vital role in the normal operation of cities and people's quality of life, and is an important part of urban infrastructure.

[0003] In water supply and drainage engineering, pipes are used to transport water. When laying water supply and drainage pipes in various construction projects, pipes are often exposed indoors or outdoors. Due to the exposure of the pipes, people, equipment, and machinery in the surrounding environment are prone to impact or collision with the pipes, resulting in pipe damage. In addition, during actual use, water supply and drainage pipes are often subjected to the impact of water flow, especially when the water flow is large, the water pressure is high, or the pipes are suddenly opened or closed. Because the support structure of the drainage pipes is rigid, it is difficult for the pipes to eliminate the force when subjected to the impact of water flow. This impact may lead to damage, leakage, or even rupture of the pipes, affecting the normal operation of the water supply and drainage system, and may also cause water waste and safety hazards. Utility Model Content

[0042] Reference Appendix Figure 1-4 This embodiment provides an impact-resistant water supply and drainage pipe, which includes: a pipe body 1, a support frame 2, a protective pipe 3, and a positioning frame 4. Connecting flanges 5 are respectively provided at both axial ends of the pipe body 1 to facilitate the connection of adjacent water supply and drainage pipes. The support frame 2 is located inside the pipe body 1, abutting against the inner wall of the pipe body 1 to improve the strength of the pipe body 1 and prevent damage to the pipe body 1 caused by external collisions or compression. The protective pipe 3 is sleeved on the outside of the pipe body 1, and has an elastic element 8 connected to the pipe body 1 inside. On the one hand, the protective pipe 3 can provide external protection for the pipe body 1, preventing accidental damage to the pipe body 1 by external machinery or personnel. On the other hand, when the pipe body 1 is impacted, it can transmit the impact force to the elastic element 8 for slow release and dissipation, avoiding structural damage to the pipe body 1 itself. The positioning frame 4 is located outside the protective pipe 3 and is used for positioning and installing the water supply and drainage pipe.

[0043] To facilitate the positioning of the protective tube 3, this embodiment constructs a coaxially sleeved limiting ring 6 and a positioning ring 7, both located outside the tube body 1 and inside the protective tube 3. The inner wall of the limiting ring 6 is fixedly connected to the tube body 1, and the outer wall of the limiting ring 6 is slidably connected to the inner wall of the positioning ring 7, with the sliding direction parallel to the axis of the limiting ring 6. That is, the positioning ring 7 can slide along the axial direction of the limiting ring 6 to connect or separate from it. The elastic element 8 is located on the outer wall of the positioning ring 7 and is used to connect the positioning ring 7 and the protective tube 3. A fixing ring plate 9 is constructed at the axial end of the limiting ring 6, and the fixing ring plate 9 abuts against the axial end of the positioning ring 7. Bolt holes with corresponding positions are constructed on both for installing connecting bolts 10.

[0044] This embodiment is attached Figure 3The example provides an embodiment in which the pipe body 1 is provided with two sets of limiting rings 6 and two sets of positioning rings 7, and an example provides an embodiment in which the fixing ring plate 9 is located at the opposite ends of the two sets of limiting rings 6. In this embodiment, when manufacturing the water supply and drainage pipe, the positioning ring 7 can be first fitted onto the limiting ring 6, and then the limiting ring 6 and the fixing ring plate 9 can be connected and tightened, and then the fixing ring plate 9 and the positioning ring 7 can be connected and tightened with bolts.

[0045] To further improve the positioning effect and installation efficiency, this embodiment constructs a limiting groove 11 on the outer wall of the limiting ring 6 and a limiting slider 12 on the inner wall of the positioning ring 7. The limiting groove 11 extends along the axial direction of the limiting ring 6, and the limiting slider 12 slides in connection with the limiting groove 11 and cooperates with it to limit the relative rotation of the limiting ring 6 and the positioning ring 7, so as to facilitate the alignment and installation of the bolt holes on the fixing ring plate 9 and the positioning ring 7.

[0046] On the other hand, the water supply and drainage pipe also includes a movable plug 13 and a movable sleeve 14. The opposite ends of the movable plug 13 and the movable sleeve 14 are rotatably connected to the outer wall of the positioning ring 7 and the inner wall of the protective pipe 3, respectively. The rotation axes of the movable plug 13 and the movable sleeve 14 are parallel to the axis of the positioning ring 7, which can improve the degree of freedom of movement of the pipe body 1 and the protective pipe 3, and better transmit and dissipate the impact force. The other end of the movable plug 13 is slidably inserted in the sliding sleeve and connected to the elastic element 8 located in the sliding sleeve. Through the compression and reset of the elastic element 8, the impact force on the pipe body 1 can be relieved, and its structure can be prevented from being damaged.

[0047] More preferably, the combination of the movable plug 13, the movable sleeve 14, and the elastic element 8 can be evenly arranged in multiple sets along the circumference and axial direction on the outside of the positioning ring 7 to improve the support and buffering effect on the tube body 1. The elastic element 8 can be selected according to actual needs, such as a compression spring. The rotational connection method between the movable plug 13 and the positioning ring 7, and the rotational connection method between the movable sleeve 14 and the protective tube 3 can be selected during implementation, for example, with... Figure 4 The diagram shows a connecting frame 15 constructed on the outer wall of the positioning ring 7 and a connecting frame 16 constructed on the inner wall of the protective tube. The connecting frame 15 and the connecting frame 16 have the same structure, each including two plates with a gap between them for installing the movable plug 13 or the movable sleeve 14. The plates are provided with shaft mounting holes for installing the shaft of the movable plug 13 or the movable sleeve 14.

[0048] To facilitate installation and structural maintenance, the distance between the axial end of the protective pipe 3 and the connecting flange 5 on the same side should be greater than zero, and the inner diameter of the protective pipe 3 should be greater than the outer diameter of the connecting flange 5, providing space for a hand or tool to be inserted into the gap between the protective pipe 3 and the pipe body 1.

[0049] Reference Appendix Figure 2-3The support frame 2 includes a support ring 21, a connecting rod 23, and a triangular support 24. The support rings 21 are coaxial with the pipe body 1 and are distributed in several directions along the axial direction of the pipe body 1. The connecting rod 23 is used to connect the support rings 21. The triangular support 24 is located inside the support rings 21, and each vertex is connected to the inner wall of the support ring 21. The triangular support 24 has a stable structure, which can increase the strength of the support rings 21 and the pipe body 1 and prevent damage to the pipe body 1 caused by external collisions or compression. Preferably, the triangular support 24 is an equilateral triangular support 24, which can provide a more evenly distributed support force for the support rings 21 and the pipe body 1.

[0050] In addition, chamfers 22 are provided at both ends of the axial direction of the support ring 21, with the chamfers 22 facing the triangular support 24, so that the connection between the support ring 21 and the inner wall of the pipe body 1 is smoother and debris is prevented from accumulating here.

[0051] The positioning frame 4 includes a connecting wing 41 and a positioning plate 42. The positioning plate 42 is parallel to the axis of the protective pipe 3, so that the axis of the protective pipe 3 and the pipe body 1 is parallel to the mounting surface of the positioning plate 42, which facilitates improved construction efficiency. The connecting wing 41 is perpendicular to the axis of the protective pipe 3 and is used to connect the positioning plate 42 and the protective pipe 3.

[0052] Compared with the prior art, the beneficial effects of this utility model include: by setting a support frame 2 inside the pipe body 1, the strength of the pipe body 1 is enhanced, and by setting a chamfer 22 on the support ring 21, debris in the water is prevented from accumulating there; by setting a protective pipe 3 and an elastic element 8 outside the pipe body 1, the pipe body 1 is protected from the outside, and the impact of water flow on the pipe body 1 can be mitigated, preventing damage to the pipe body 1 and improving the service life of the water supply and drainage pipeline.

[0053] The above are preferred embodiments of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
