Description

Technical Field

[0001] This utility model relates to the field of sealing ring technology, specifically a full-circumference rubber sealing ring for reinforced concrete pipes in drainage pipe networks. Background Technology

[0002] In areas such as municipal drainage and industrial park sewage discharge, reinforced concrete pipes have become the core material for drainage network construction due to their advantages of high strength, strong corrosion resistance, and long service life. The sealing performance of the pipe joints directly determines whether there is a risk of leakage in the drainage network, so rubber sealing rings are needed to achieve joint sealing.

[0003] In existing drainage pipe networks, rubber sealing rings used for connecting reinforced concrete pipes are mostly installed on the outside of the pipe connection point. The sealing ring's elastic deformation fits the outer wall of the pipe, preventing sewage and rainwater from leaking out. However, the impact of water flow in the drainage pipe network, slight displacement of the pipe caused by soil settlement or ground load, will generate a continuous relative force between the sealing ring and the outer wall of the pipe, causing the sealing ring to gradually deviate from its installation position. In addition, although the outer wall of reinforced concrete pipes has a certain degree of roughness, the pipe surface may become smooth due to wear and dirt accumulation during long-term use, reducing the frictional resistance between the sealing ring and the outer wall of the pipe, further exacerbating the loosening trend.

[0004] Therefore, a full-circumference rubber sealing ring for reinforced concrete pipes in drainage pipe networks is proposed. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a full-circumference rubber sealing ring for reinforced concrete pipes in drainage pipe networks, so as to solve the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution.

[0007] This utility model provides a full-circumference rubber sealing ring for reinforced concrete pipes in drainage pipe networks, including a sealing ring body, and a fastening mechanism is provided on the outside of the sealing ring body; Both sides of the sealing ring body are provided with annular sealing grooves, and the side of the annular sealing groove facing the center of the sealing ring body is set with an inclined surface; The fastening mechanism includes two arc-shaped fastening plates symmetrically wrapped around the outside of the sealing ring body. The inner sidewalls of the two arc-shaped fastening plates are fixed with arc-shaped pressing plates that are in contact with the outside of the sealing ring body. A locking mechanism is provided on the opposite side of the two arc-shaped fastening plates.

[0008] Preferably, the annular sealing groove is provided with a plurality of evenly distributed annular anti-slip ridges on the side away from the center of the sealing ring body, and the cross-section of the annular anti-slip ridges is semi-circular.

[0009] Preferably, the inner wall of the sealing ring body is provided with arc-shaped guide grooves on both sides.

[0010] Preferably, the locking mechanism includes fixing rings fixedly disposed at both ends of the two arc-shaped fastening plates, and a set of locking bolts is provided between two adjacent fixing rings.

[0011] Preferably, the inner wall of the arc-shaped clamping plate is provided with anti-slip texture.

[0012] Preferably, both the arc-shaped fastening plate and the arc-shaped pressing plate are made of stainless steel elastic bending plate.

[0013] Compared with the prior art, the present invention has the following beneficial effects: 1. By setting up a fastening mechanism, two arc-shaped fastening plates symmetrically wrap around the sealing ring body. The anti-slip texture on the inner side of the arc-shaped clamping plate enhances the friction with the sealing ring body. Then, the fixing ring and locking bolt group of the locking mechanism apply uniform radial pressure, which can reliably lock the sealing ring body and prevent it from loosening due to water flow impact or slight pipe displacement. At the same time, the semi-circular anti-slip ridge in the annular sealing groove can increase the frictional resistance with the outer wall of the pipe, doubly preventing the sealing ring from shifting, significantly improving the sealing stability during long-term use, and solving the problem of existing external sealing rings being prone to loosening and reducing sealing performance.

[0014] 2. By setting annular sealing grooves on both sides of the sealing ring body and adopting an inclined surface design facing the center, it can better fit the curvature of the outer wall of the reinforced concrete pipe and increase the sealing contact area; and the radial pressure applied by the fastening mechanism can make the sealing ring body fit the pipe more tightly, reduce the sealing gap, effectively block the leakage of sewage and rainwater in the pipe, and meet the core requirements of drainage pipe network for sealing performance.

[0017] A full-circumference rubber sealing ring for reinforced concrete pipes in drainage networks, such as Figure 1-3 As shown, the device includes a sealing ring body 1. Both sides of the sealing ring body 1 have annular sealing grooves 3. The side of the annular sealing groove 3 facing the center of the sealing ring body 1 is inclined. Multiple evenly distributed annular anti-slip protrusions 4 are fixedly provided on the side of the annular sealing groove 3 away from the center of the sealing ring body 1. The cross-section of the annular anti-slip protrusions 4 is semi-circular. The annular anti-slip protrusions 4 can increase the frictional resistance between the sealing ring body 1 and the outer wall of the pipe. Both sides of the inner wall of the sealing ring body 1 are provided with arc-shaped flow guide grooves 5, which can guide the water flow in the pipe smoothly through the connection point, reducing the impact of the water flow on the sealing ring body 1.

[0018] The sealing ring body 1 is provided with a fastening mechanism 2 on its exterior. The fastening mechanism 2 includes two arc-shaped fastening plates 21 symmetrically wrapped around the exterior of the sealing ring body 1. The inner sidewalls of the two arc-shaped fastening plates 21 are fixed with arc-shaped pressure plates 22 that are in contact with the exterior of the sealing ring body 1. The inner sidewalls of the arc-shaped pressure plates 22 are provided with anti-slip textures, which can increase the frictional resistance between the arc-shaped pressure plates 22 and the sealing ring body 1. Both the arc-shaped fastening plates 21 and the arc-shaped pressure plates 22 are made of stainless steel elastic bending plates. A locking mechanism 23 is provided on one side opposite to the two arc-shaped fastening plates 21. The locking mechanism 23 includes fixing rings 231 fixed at both ends of the two arc-shaped fastening plates 21. A locking bolt group 232 is provided between two adjacent fixing rings 231. The locking bolt group 232 is composed of bolts and nuts.

[0019] In summary: When in use, first, the sealing ring body 1 is placed on the outside of the joint of two reinforced concrete pipes, so that the pipe joint ends are embedded in the annular sealing grooves 3 on both sides of the sealing ring body 1. The inclined surface design of the annular sealing groove 3 facing the center of the sealing ring body 1 can better adapt to the curvature of the outer wall of the pipe. At the same time, the multiple semi-circular anti-slip protrusions 4 on the side of the annular sealing groove 3 away from the center will be in close contact with the outer wall of the pipe, increasing the frictional resistance between the sealing ring body 1 and the outer wall of the pipe, and initially preventing the sealing ring body 1 from sliding relative to the pipe. Subsequently, the two arc-shaped fastening plates 21 of the fastening mechanism 2 are symmetrically wrapped around the outside of the sealing ring body 1, so that the arc-shaped pressure plate 22 fixed on the inner side wall of the arc-shaped fastening plate 21 fits against the outer wall of the sealing ring body 1. The anti-slip texture on the inner side wall of the arc-shaped pressure plate 22 further enhances the friction with the sealing ring body 1, preventing the fastening mechanism 2 from sliding itself. Then, it is fixed by the locking mechanism 23. The fixing rings 231 at both ends of the two arc-shaped fastening plates 21 are aligned, and the locking bolt group 232 is passed through the adjacent fixing rings 231 and tightened, so that the two arc-shaped fastening plates 21 drive the arc-shaped pressure plate 22 to apply uniform radial pressure to the sealing ring body 1, so that the sealing ring body 1 fits further against the outer wall of the pipe, enhancing the sealing effect. At the same time, the mechanical locking action of the fastening mechanism 2 prevents the sealing ring body 1 from loosening due to water flow impact or slight displacement of the pipe. In addition, the arc-shaped guide grooves 5 on both sides of the inner wall of the sealing ring body 1 can guide the water flow in the pipe to pass smoothly through the docking part, reduce the impact of the water flow on the sealing ring body 1, and further ensure that the sealing ring body 1 is not easy to loosen during long-term use, thus ensuring the sealing performance of the drainage pipe network.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
