Description

Technical Field

[0001] This utility model relates to the field of water supply and drainage pipeline technology, and in particular to a drainage pipeline connection structure for water supply and drainage engineering. Background Technology

[0002] Municipal water supply and drainage pipelines refer to the rainwater and sewage pipes under municipal roads, and are commonly referred to as municipal drainage pipelines in engineering. Based on the current state of infrastructure under municipal roads in China, various pipelines are typically installed, such as power, telecommunications, gas, water supply, and drainage pipes. Drainage pipelines, considering rainwater and sewage separation measures—that is, rainwater is generally discharged into nearby rivers, while sewage is discharged into sewage treatment plants—comprising both rainwater and sewage pipes. With the gradual development of society and the further improvement of drainage engineering, the application of municipal water supply and drainage pipelines is becoming increasingly widespread.

[0003] Most existing water supply and drainage pipes are connected using flanges and then fixed with bolts. During pipeline operation, the connection points are affected by fluid pulsation and foundation settlement, which will generate circumferential rotational stress. The force will be applied to the bolts, causing the connection to loosen. Utility Model Content

[0004] Therefore, it is necessary to provide a drainage pipe connection structure for water supply and drainage engineering to address the problem that the connection of water supply and drainage pipes is easily affected by rotational stress, which can lead to loosening of the connection.

[0005] A drainage pipe connection structure for water supply and drainage engineering, comprising:

[0006] Two drain pipes, with connecting plates fixedly connected to the surfaces of the drain pipes;

[0007] The connecting mechanism further includes a connecting flange and multiple connecting rods disposed between the two drain pipes. The drain pipes and the connecting flange are fixedly installed through the connecting rods and the connecting plate. Nuts are threaded to both ends of the connecting rods.

[0008] The surface of the drain pipe is fixedly connected with multiple reinforcing plates arranged in a ring. The surface of the connecting rod is provided with a locking plate that fits tightly with the reinforcing plates. The side of the reinforcing plate away from the drain pipe is provided with multiple grooves. The end of the locking plate near the drain pipe is provided with a protrusion that matches the groove.

[0009] In one embodiment, a buckle is fixedly connected to the end of the locking plate away from the drain pipe, and the buckle engages with the connecting flange.

[0010] In one embodiment, a sealing gasket is provided at the connection between the drain pipe and the connecting flange, and the opposite sides of the two sealing gaskets extend into the corresponding drain pipe.

[0011] In one embodiment, each of the two gaskets has a protrusion on its opposite side, and the connecting flange has two mounting grooves that mate with the corresponding protrusions.

[0012] In one embodiment, the middle part of the connecting rod is a smooth rod, and both ends of the connecting rod are provided with threads, and the connecting rod and the nut are fixedly connected by the threads.

[0013] In one embodiment, a gasket is provided between the nut and the locking plate, and the gasket is a rubber material component.

[0014] In one embodiment, the number of connecting rods is six, and the number of nuts is twice the number of connecting rods.

[0015] In one embodiment, the reinforcing plate and locking plate are flush with the side away from the connecting flange. Beneficial effects

[0016] 1. The above-mentioned connection mechanism utilizes the cooperation of the reinforcing plate and the locking plate, with the protrusion embedded in the groove. When the water supply and drainage pipes are vibrated or affected by external forces, the drainage pipes will not rotate, and the connection will not be affected by rotational stress, thus increasing the stability of the two drainage pipes. At the same time, the buckles can complete the initial connection between the connecting plate and the connecting flange, which facilitates the initial pipe connection work. Even if the nut is removed, the multiple buckles will keep the connection between the drainage pipe and the connecting flange, and there will be no complete separation, thus increasing the stability of the drainage pipe connection.

[0017] 2. The sealing gasket can utilize the recessed mounting portion formed on the surface to provide a wrap-around seal to the end and opening of the drain pipe, increasing the sealing performance between the connecting flange and the drain pipe. The gasket forms a frustum shape at the opening where it connects to the drain pipe, reducing obstruction to water flow. At the same time, the convex part and the mounting groove cooperate with each other, making the initial installation of the gasket and connecting flange more convenient and preventing misalignment, resulting in more accurate positioning.

[0030] The following is combined Figures 1-4 This invention describes the drainage pipe connection structure for water supply and drainage engineering.

[0031] In one embodiment, a drainage pipe connection structure for water supply and drainage engineering includes:

[0032] Two drain pipes 100, and a connecting plate 110 is fixedly connected to the surface of the drain pipes 100;

[0033] The connecting mechanism 200 also includes a connecting flange 210 and multiple connecting rods 220 disposed between two drain pipes 100. The drain pipes 100 and the connecting flange 210 are fixedly installed through the connecting rods 220 and the connecting plate 110. Both ends of the connecting rods 220 are threaded with nuts 221.

[0034] Multiple reinforcing plates 120 arranged in a ring are fixedly connected to the surface of the drain pipe 100. The surface of the connecting rod 220 is provided with a locking plate 240 that fits tightly with the reinforcing plate 120. Multiple grooves are provided on the side of the reinforcing plate 120 away from the drain pipe 100. A protrusion matching the groove is provided at the end of the locking plate 240 near the drain pipe 100.

[0035] like Figure 3As shown, a clip 241 is fixedly connected to the end of the locking plate 240 away from the drain pipe 100, and the clip 241 engages with the connecting flange 210. The U-shaped clip 241 can complete the initial connection between the connecting plate 110 and the connecting flange 210 in the early stage of installation, making the later installation more convenient. At the same time, even if the nut 221 is removed, multiple clips 241 will keep the connection between the drain pipe 100 and the connecting flange 210, and will not completely detach, increasing the stability of the drain pipe 100 connection.

[0036] like Figure 3 and Figure 4 As shown, a sealing gasket 230 is provided at the connection between the drain pipe 100 and the connecting flange 210, with the opposing sides of the two sealing gaskets 230 extending into the corresponding drain pipe 100. When the drain pipe 100 and the connecting flange 210 are connected, the surface of the sealing gasket 230 will contact the drain pipe 100, and the end of the sealing gasket 230 will extend into the drain pipe 100, providing a wrap-around seal to the end and opening of the drain pipe 100, increasing the sealing performance between the connecting flange 210 and the drain pipe 100. The opening at the connection between the sealing gasket 230 and the drain pipe 100 is frustoconical, reducing obstruction to water flow.

[0037] Both gaskets 230 have protrusions 231 on opposite sides, and the connecting flange 210 has two mounting grooves 211 that mate with the corresponding protrusions 231. During initial installation, the protrusions 231 are pressed into the mounting grooves 211 to complete the connection between the gaskets 230 and the connecting flange 210. Subsequent installation of the drain pipe 100 and the connecting flange 210 is then easier, prevents misalignment, and ensures more precise positioning.

[0038] like Figure 1 , Figure 2 and Figure 3 As shown, the middle part of the connecting rod 220 is a smooth rod, and both ends of the connecting rod 220 are threaded. The connecting rod 220 and the nut 221 are fixedly connected by the thread. The connecting rod 220 passes longitudinally through the two locking plates 240, the two connecting plates 110 and the connecting flange 210. The nut 221 is rotated by the thread to complete the final positioning and locking of the pipeline.

[0039] A washer made of rubber is provided between the nut 221 and the locking plate 240. The washer increases the friction between the nut 221 and the locking plate 240, increases the stability of the locking, and prevents loosening later.

[0040] There are six connecting rods 220, and the number of nuts 221 is twice the number of connecting rods 220. During installation, two nuts 221 and connecting rods 220 are grouped together. Six groups need to be connected sequentially during installation. The ring-shaped connecting parts provide better stability.

[0041] The reinforcing plate 120 and the locking plate 240 are flush with the side away from the connecting flange 210. If the locking plate 240 and the reinforcing plate 120 are longitudinally offset later, it can be observed intuitively, which is convenient for later maintenance work.

[0042] Working principle: During the initial pipe connection, two sealing gaskets 230 are first installed inside the connecting flange 210 in the connecting mechanism 200 to complete the connection of the two drain pipes 100 and the connecting flange 210. The locking plate 240 and the reinforcing plate 120 are then snapped together. The locking plate 240 and the connecting flange 210 are then snapped together using their clips 241. Multiple locking plates 240 are completed in sequence. After the initial connection is completed, multiple connecting rods 220 are installed. Finally, nuts 221 are used for final locking.

[0043] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0044] The above-described embodiments are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the appended claims.
