Description

Technical Field

[0001] This utility model relates to the field of drainage pipe technology, and in particular to a high-efficiency anti-clogging drainage pipe joint for rainwater and sewage separation renovation. Background Technology

[0002] Rainwater and sewage separation is an important part of urban infrastructure construction. It aims to collect and treat rainwater and sewage separately to improve water resource utilization efficiency and reduce water pollution. Drainage pipes mainly undertake the drainage of rainwater, sewage, and farmland irrigation. Pipe fittings are needed to connect adjacent drainage pipes.

[0003] In pipeline connection engineering, the horizontal joint at two ports is a commonly used connection component. The horizontal joint connects two adjacent drainage pipes on the same axis, thereby ensuring the smooth operation of the pipeline system, reducing the risk of leakage, and ensuring the stability and safety of the drainage pipeline during operation.

[0004] However, during the actual installation of drainage pipes, due to the influence of the drainage pipe installation environment, it is impossible to ensure that two adjacent pipes are on the same axis. The horizontal joints at the two ports cannot compensate for and adjust the deviation of the pipe axis, resulting in low practicality. Utility Model Content

[0005] Therefore, it is necessary to provide a high-efficiency anti-clogging drainage pipe joint for rainwater and sewage separation renovation to address the problem that the horizontal joint at both ports cannot compensate for and adjust the deviation of the pipe axis and has low practicality.

[0006] Includes: a connecting pipe, wherein the middle part of the connecting pipe is a corrugated pipe;

[0007] The connecting mechanism includes two round rods, each with three first nuts threaded onto its surface. Both ends of the connecting tube are fixedly connected to connecting plates. One connecting plate has two first fixing blocks fixedly connected to its surface, and the other connecting plate has two second fixing blocks slidably connected to its inner wall. Both the surfaces of the first and second fixing blocks have round holes. The top of the second fixing block is fixedly connected to a locking plate, which has multiple evenly distributed locking slots at its top.

[0008] In one embodiment, the connecting mechanism further includes two mounting plates fixedly connected to the surface of another connecting plate. The inner wall of each mounting plate is threaded with a threaded rod. The bottom end of the threaded rod passes through the mounting plate and is rotatably connected to a fixing plate. The bottom end of the fixing plate is fixedly connected with multiple evenly distributed locking blocks. This facilitates fixing the positions of the two connecting plates after they have deviated from their axial positions following the connection of the drain pipe.

[0009] In one embodiment, the connecting plate has an annular groove at the end away from the connecting pipe, and a sealing gasket is fixedly connected to one end of the inner wall of the annular groove. This helps to increase the sealing performance when the drain pipe is connected to the connecting plate.

[0010] In one embodiment, the two ends of the round rod are threaded, and the round rod and the first nut are fixedly connected by the threads. This facilitates the connection between the first nut and the round rod to tighten against the first fixing block and the second fixing block.

[0011] In one embodiment, the vertical cross-section of the card block is an isosceles triangle, and the shape of the card block matches the shape of the card slot. This ensures stability when the card block and card slot are engaged.

[0012] In one embodiment, a washer, which is a rubber component, is provided between the first nut and the second fixing block and between the first fixing block. This increases the stability of the first nut's locking and prevents it from loosening later.

[0013] In one embodiment, a limiting rod is fixedly connected to the top of the fixing plate, and the top of the limiting rod extends through the mounting plate. This facilitates limiting the movement path of the fixing plate.

[0014] In one embodiment, the first fixing block and the second fixing block are on the same horizontal plane. This ensures a secure connection between the round rod and the first fixing block (i.e., the second fixing block).

[0015] Beneficial effects

[0016] 1. When connecting two adjacent drainage pipes, this scheme uses the corrugated part of the connecting pipe to compensate for and adjust the deviation of the two pipe axes, improving the practicality of connecting the two adjacent drainage pipes. Through the interaction of the round rod, the first fixing block, the second fixing block, and the clamping plate and clamping block in the connecting mechanism, it is beneficial to fix the position of the two connecting plates after the axis deviation after the drainage pipe is connected. Under the action of the round rod and the first nut, it is beneficial to fix the distance between the two connecting plates after the drainage pipe is connected, thereby fixing the deformed connecting pipe and ensuring the stability of the deformation during the connection process. This ensures the stability of the connection between the connecting pipe and the two connecting plates for the two drainage pipes.

[0017] 2. When connecting the drain pipe, pressing one end of the drain pipe tightly against the sealing gasket helps to increase the sealing performance when the drain pipe is connected to the connecting plate. Attached Figure Description

[0030] The following is combined Figures 1-4 This invention describes a high-efficiency anti-clogging drainage pipe joint for rainwater and sewage separation renovation.

[0031] In one embodiment, a high-efficiency anti-clogging drainage pipe joint for rainwater and sewage separation renovation includes: a connecting pipe 100, the middle part of which is a corrugated pipe;

[0032] The connecting mechanism 200 includes two round rods 210, three first nuts 250 are threaded onto the surface of the round rods 210, and connecting plates 220 are fixedly connected to both ends of the connecting tube 100. Two first fixing blocks 230 are fixedly connected to the surface of one connecting plate 220, and two second fixing blocks 240 are slidably connected to the inner wall of the other connecting plate 220. Round holes are opened on the surface of the first fixing blocks 230 and the surface of the second fixing blocks 240. A clamping plate 270 is fixedly connected to the top of the second fixing block 240, and multiple evenly distributed clamping slots are opened on the top of the clamping plate 270.

[0033] In this embodiment, the connecting pipe 100 is a PVC component, and flanges are fixedly connected to both ends of the connecting pipe 100. The inner wall of the connecting pipe 100 is smooth and has good corrosion resistance. The corrugated pipe in the middle of the connecting pipe 100 is a rubber component with good corrosion resistance. Furthermore, when connecting two adjacent pipes, the corrugated pipe in the middle is flexible and can be bent and deformed within a certain range.

[0034] The two first fixing blocks 230 and the two second fixing blocks 240 are symmetrical about the center of the connecting plate 220. The inner wall of the other connecting plate 220 is provided with a moving groove that matches the second fixing block 240. When the two connecting plates 220 are located on the same axis, one end of the second fixing block 240 in the moving groove is located in the middle of the moving groove.

[0035] like Figure 3 As shown, the connecting mechanism 200 also includes two mounting plates 260 fixedly connected to the surface of another connecting plate 220. The inner wall of the mounting plate 260 is threaded with a threaded rod 261. The bottom end of the threaded rod 261 passes through the mounting plate 260 and is rotatably connected to a fixing plate 262. The bottom end of the fixing plate 262 is fixedly connected with a plurality of evenly distributed locking blocks 263.

[0036] In this embodiment, when the second fixing block 240 moves to the farthest distance away from the connecting plate 220 and when the second fixing block 240 moves to the closest distance towards the connecting plate 220, some of the card blocks 263 still overlap with some of the card slots on the vertical plane.

[0037] like Figure 2 As shown, an annular groove 221 is provided at one end of the connecting plate 220 away from the connecting pipe 100, and a sealing gasket 222 is fixedly connected to one end of the inner wall of the annular groove 221.

[0038] In this embodiment, the sealing gasket 222 is a rubber component with good corrosion resistance. When one end of the drain pipe is inserted into the annular groove 221, the surface of the drain pipe contacts the inner wall of the annular groove 221, and one end of the drain pipe is pressed against the sealing gasket 222.

[0039] like Figure 2 As shown, the two ends of the round rod 210 are provided with threads, and the round rod 210 and the first nut 250 are fixedly connected by the threads.

[0040] In this embodiment, the diameter of the circular holes opened in the first fixing block 230 and the second fixing block 240 matches the diameter of the circular rod 210. In the initial state, the two circular rods 210 pass through the first fixing block 230 and the second fixing block 240 longitudinally, respectively. In the initial state, the two first nuts 250 are connected to the bare rod position of the circular rod 210.

[0041] like Figure 3As shown, the vertical cross-section of the card block 263 is an isosceles triangle, and the shape of the card block 263 matches the shape of the card slot.

[0042] In this embodiment, when the card block 263 enters the card slot, the surface of the card block 263 is in contact with the inner wall of the card slot, and the bottom end of the fixing plate 262 is pressed against the top end of the card plate 270.

[0043] like Figure 3 As shown, a gasket is provided between the first nut 250 and the second fixing block 240 and the first fixing block 230. The gasket is a rubber material component.

[0044] In this embodiment, the gasket can increase the friction between the first nut 250, the first fixing block 230, and the second fixing block 240, thereby increasing the stability of the locking and making it less likely to loosen later.

[0045] like Figure 3 As shown, a limiting rod 264 is fixedly connected to the top of the fixing plate 262, and the top of the limiting rod 264 extends through the mounting plate 260.

[0046] In this embodiment, the surface of the limiting rod 264 is slidably connected to the inner wall of the mounting plate 260, and the limiting rod 264 limits the movement path of the fixing plate 262.

[0047] like Figure 2 As shown, the first fixing block 230 and the second fixing block 240 are on the same horizontal plane. This ensures the fixing effect after the round rod 210 passes through the first fixing block 230 and the second fixing block 240.

[0048] Working principle: When connecting two adjacent drain pipes, the opposite ends of the two drain pipes are inserted into the two annular grooves 221 respectively and pressed against the sealing gaskets 222. When the two drain pipes are connected to the connecting pipe 100, the corrugated part of the connecting pipe 100 will compensate and adjust the deviation of the two pipe axes. When the drain pipe installation causes a positional deviation between the two connecting plates 220 on the same axis, the two second fixing blocks 240 will move on the inner wall of the other first fixing block 230 under the action of the round rod 210. After one end of the drain pipe is inserted into the annular groove 221, the flanges on the surface of the drain pipe are pressed against the corresponding connecting plates 220 respectively. The flanges are then secured to the connecting plates using bolts and second nuts. The connecting plate 220 is connected and fixed to complete the installation of the drain pipe and the connecting pipe 100. After installation, the threaded rod 261 is rotated to push the fixing plate 262 and drive the locking block 263 to move downward, so that the locking block 263 engages with the locking groove, thereby fixing the position of the two connecting plates 220 after the deviation on the axis. The first nut 250 is rotated by the thread, so that one of the first nuts 250 abuts against the first fixing block 230, and the other two first nuts 250 abut against the two sides of the second fixing block 240 respectively, thereby fixing the distance between the two connecting plates 220. After this operation is completed, the fixed installation of the adjacent connecting pipe 100 to the two adjacent drain pipes is completed.

[0049] 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.

[0050] 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.
