Description

Technical Field

[0001] The present invention relates to the technical field of water supply and drainage pipes, and in particular to a water supply and drainage pipe resistant to impact. Background Art

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

[0003] In the water supply and drainage project, pipes are needed to transport water. When arranging water supply and drainage pipes in various construction projects, the pipes are often exposed indoors or outdoors of the building. Due to the exposure of the pipes, the surrounding personnel, equipment, machinery, etc. in the environment are likely to cause impact or collision to the pipes, resulting in pipe damage. In addition, during actual use, the water supply and drainage pipes are often impacted by water flow, especially when the water flow rate is large, the water pressure is high, or the pipes are suddenly opened or closed. Since the supports of the drainage pipes are rigid structures, when the pipes are impacted by water flow, it is difficult to eliminate the acting force on themselves. Such impact may cause damage, leakage or even rupture of the pipes, affecting the normal operation of the water supply and drainage system, and at the same time may also cause waste of water resources and potential safety hazards. Summary of the Invention

[0004] The purpose of the present invention is to provide a water supply and drainage pipe resistant to impact to solve the deficiencies in the above background art.

[0005] The technical solution of the present invention is: a water supply and drainage pipe resistant to impact, which includes:

[0006] A pipe body, and connecting flanges are respectively configured at both axial ends of the pipe body;

[0007] A support frame, which is disposed inside the pipe body and abuts against the inner wall of the pipe body;

[0008] A protective pipe, which is sleeved outside the pipe body, and an elastic element connecting the pipe body is configured on the inner wall;

[0009] A positioning frame, which is disposed outside the protective pipe and is used for positioning and installing the water supply and drainage pipe.

[0010] Further, a limiting ring and a positioning ring are coaxially sleeved on the inner side of the protective pipe. The elastic element is located on the outer wall of the positioning ring. The inner wall of the positioning ring is slidably connected to the limiting ring, and the inner wall of the limiting ring is fixedly connected to the pipe body; a fixing ring plate is configured at the axial end of the limiting ring, and the axial end of the positioning ring is detachably connected to the fixing ring plate.

[0011] Further, one of the inner wall of the positioning ring and the outer wall of the limiting ring is configured with a limiting chute, and the other is configured with a limiting slider. The limiting chute extends along the axial direction of the limiting ring, and the limiting slider cooperates with the limiting chute to limit the relative rotation of the limiting ring and the positioning ring.

[0012] Further, the water supply and drainage pipeline includes a movable plug and a movable sleeve. The separated ends of the movable plug and the movable sleeve are respectively rotatably connected to the outer wall of the positioning ring and the inner wall of the protective pipe, and the rotating shaft is parallel to the axis of the positioning ring. The other end of the movable plug slidably penetrates through the sliding sleeve and is connected to the elastic element located in the sliding sleeve.

[0013] Further, the distance between the axial end of the protective pipe and the connecting flange on the same side is greater than zero, and the inner diameter of the protective pipe is greater than the outer diameter of the connecting flange.

[0014] Further, the support frame includes a support ring, a connecting rod, and a triangular support. The support ring is coaxial with the pipe body and is dispersed along the axial direction of the pipe body in several numbers. The connecting rod is used to connect the several support rings. The triangular support is located inside the support ring, and each vertex is respectively connected to the inner wall of the support ring.

[0018] The beneficial effects of the present invention are as follows: By arranging a support frame inside the pipe body, the strength of the pipe body is enhanced. At the same time, by arranging chamfers on the support ring, the accumulation of sundries in the water is prevented. By arranging a protective pipe and an elastic element outside the pipe body, on the one hand, protection is provided to the pipe body from the outside, and on the other hand, the water flow impact received by the pipe body can be buffered to prevent the pipe body from being damaged and improve the service life of the water supply and drainage pipeline.

[0040] The technical solutions of the embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0041] In the description of the embodiments of the present invention, it should be understood that the orientation or positional relationship indicated by terms such as "top" and "bottom" is based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as a limitation to the present invention. In the description of the present invention, it should be noted that unless otherwise clearly specified and defined, the terms "arranged" and "connected" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be directly connected, or indirectly connected through an intermediate medium, and it can be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood through specific situations.

[0042] Refer to the attached Figures 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 configured 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 configured inside the pipe body 1 and abuts 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 collision or extrusion; the protective pipe 3 is sleeved outside the pipe body 1, and an elastic element 8 connecting the pipe body 1 is configured inside. On the one hand, the protective pipe 3 can provide external protection for the pipe body 1 to avoid damage to the pipe body 1 by external machinery or personnel. On the other hand, when the pipe body 1 is impacted, the impact force can be transmitted to the elastic element 8 and slowly released and dissipated to avoid structural damage to the pipe body 1 itself; the positioning frame 4 is configured outside the protective pipe 3 and is used for positioning and installing the water supply and drainage pipe.

[0043] For the convenience of positioning the protective pipe 3, this embodiment configures a coaxially sleeved limit ring 6 and a positioning ring 7. Both are located outside the pipe body 1 and inside the protective pipe 3. The inner wall of the limit ring 6 is fixedly connected to the pipe body 1, and the outer wall of the limit ring 6 is slidably connected to the inner wall of the positioning ring 7, and the sliding direction is parallel to the axis of the limit ring 6, that is, the positioning ring 7 can slide along the axis direction of the limit ring 6 to be connected or separated 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 pipe 3; a fixed ring plate 9 is configured at the axial end of the limit ring 6, and the fixed ring plate 9 abuts against the axial end of the positioning ring 7, and bolt holes corresponding to each other in position are respectively configured on both of them for installing a connecting bolt 10.

[0044] This embodiment attaches Figure 3Exemplarily, a solution is presented where two sets of limiting rings 6 and two sets of positioning rings 7 are provided outside the pipe body 1, and a solution is presented where the fixed ring plate 9 is located at the separated ends of the two sets of limiting rings 6. In this solution, when manufacturing the water supply and drainage pipe, the positioning ring 7 can be sleeved on the limiting ring 6 first, then the limiting ring 6 and the fixed ring plate 9 are firmly connected, and then the fixed ring plate 9 and the positioning ring 7 are firmly connected with bolts.

[0045] To further improve the positioning effect and installation efficiency, in this embodiment, a limiting chute 11 is configured on the outer wall of the limiting ring 6, and a limiting slider 12 is configured on the inner wall of the positioning ring 7. The limiting chute 11 extends along the axial direction of the limiting ring 6, and the limiting slider 12 is slidably connected to the limiting chute 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 fixed ring plate 9 and the positioning ring 7.

[0046] On the other hand, the water supply and drainage pipe further includes a movable plug 13 and a movable sleeve 14. The separated ends of the movable plug 13 and the movable sleeve 14 are respectively rotatably connected to the outer wall of the positioning ring 7 and the inner wall of the protective pipe 3, and the rotation axes of the movable plug 13 and the movable sleeve 14 are respectively parallel to the axis of the positioning ring 7, which can improve the freedom of movement between 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 slidably penetrates through the sliding sleeve and is connected to the elastic element 8 located in the sliding sleeve. Through the compression and reset of the elastic element 8, the impact force received by the pipe body 1 can be slowly released to avoid damage to its structure.

[0047] More preferably, a plurality of groups of the combination of the movable plug 13, the movable sleeve 14 and the elastic element 8 can be evenly configured along the circumferential and axial directions on the outside of the positioning ring 7 respectively to improve the support and buffering effect on the pipe body 1. The elastic element 8 can be selected according to actual needs, such as a compression spring. The rotational connection method of the movable plug 13 and the positioning ring 7 and the rotational connection method of the movable sleeve 14 and the protective pipe 3 can be selected during implementation, for example, as shown in the attached Figure 4 A connection frame one 15 is configured on the outer wall of the positioning ring 7, and a connection frame two 16 is configured on the inner wall of the protective pipe. The structures of the connection frame one 15 and the connection frame two 16 are the same and respectively include two plate bodies with a gap between them for installing the movable plug 13 or the movable sleeve 14, and a rotating shaft installation hole is configured on the plate body for installing the rotating 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 connection flange 5 on the same side should be greater than zero, and the inner diameter of the protective pipe 3 is greater than the outer diameter of the connection flange 5 to provide a space that allows a hand or tool to reach into the gap between the protective pipe 3 and the pipe body 1.

[0049] Refer to the attached Figures 2-3, the 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 dispersed along the axial direction of the pipe body 1 in several numbers; the connecting rod 23 is used to connect several support rings 21; the triangular support 24 is located inside the support ring 21, and each vertex is respectively connected to the inner wall of the support ring 21. The structure of the triangular support 24 is stable, which can increase the strength of the support ring 21 and the pipe body 1, and prevent the pipe body 1 from being damaged caused by external collision or extrusion. Preferably, the triangular support 24 is an equilateral triangular support 24, and the equilateral triangular support 24 can provide a more evenly distributed supporting force for the support ring 21 and the pipe body 1.

[0050] In addition, chamfers 22 are respectively configured at both axial ends of the support ring 21, and the chamfers 22 face 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 accumulation at this place is avoided.

[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 axes of the protective pipe 3 and the pipe body 1 are parallel to the installation surface of the positioning plate 42, which is convenient for improving the 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 the present invention include: by arranging the support frame 2 inside the pipe body 1 to strengthen the strength of the pipe body 1, and at the same time by arranging the chamfers 22 on the support ring 21 to prevent debris in the water from accumulating here; by arranging the protective pipe 3 and the elastic element 8 outside the pipe body 1, on the one hand, it provides protection for the pipe body 1 from the outside, and on the other hand, it can slow down the water flow impact received by the pipe body 1, prevent the pipe body 1 from being damaged, and improve the service life of the water supply and drainage pipeline.

[0053] The above is the preferred implementation manner of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present invention, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present invention.
