Description

Technical Field

[0001] The utility model relates to the field of drainage pipes for municipal engineering, and particularly relates to a drainage pipe for municipal engineering. Background Technique

[0002] The drainage pipes for municipal engineering are an important part of urban infrastructure, and play a crucial role in urban flood control and drainage, preventing groundwater pollution and improving the quality of urban life. Drainage pipes refer to the pipelines and their ancillary facilities that collect and discharge sewage, wastewater and rainwater. Drainage pipes include all pipes that play a drainage role, such as main pipes, branch pipes and pipes leading to treatment plants, regardless of whether they are built on streets or anywhere else.

[0003] However, in the prior art, since the connection between pipes in the drainage pipes for municipal engineering is usually fixed only by bolt structures, the stability is not good, and the pipes are prone to looseness due to reasons such as rust after long-term use. Content of the Utility Model

[0004] The purpose of the utility model is to provide a drainage pipe for municipal engineering to solve the problems raised in the above background technique.

[0005] To solve the above technical problems, the technical solution of the utility model is that a drainage pipe for municipal engineering includes a first pipe and a second pipe. A connection mechanism is arranged between the first pipe and the second pipe. The connection mechanism includes a partition plate. Protective mechanisms are sleeved on the surfaces of the first pipe and the second pipe respectively. The protective mechanism includes a protective sleeve.

[0006] As a further scheme of the utility model: an insertion pipe is arranged on one side of the partition plate. External threads are provided on the outer side wall of the insertion pipe. A plurality of groups of threaded rods are equidistantly penetrated through the side wall of the partition plate. First nuts are threaded on both ends of the threaded rods.

[0007] As a further scheme of the utility model: fixing rings are sleeved on both ends of the second pipe. Fixing grooves are arranged on one side of the fixing rings.

[0008] As a further scheme of the utility model: the two partition plates are respectively sleeved at both ends of the first pipe. Internal threads meshing with the external threads are arranged on the inner side wall of the fixing groove. The insertion pipe is arranged inside the fixing groove through the cooperation of the external threads and the internal threads. The partition plate is arranged on one side of the fixing ring through the cooperation of the insertion pipe, the external threads and the fixing groove in a threaded manner. One end of the threaded rod penetrates through the partition plate and the fixing ring.

[0009] As a further solution of the utility model: a plurality of groups of slots are provided on the side wall of the protective sleeve and at both ends, and a plurality of groups of chutes are provided on the side walls of the first pipe and the second pipe near the protective sleeve. A screw rod is arranged inside the chute, a slider is slidably arranged on the screw rod, and a second nut is arranged on the screw rod at a position on one side of the slider. A positioning ring is sleeved on the first pipe and the second pipe, and a plurality of groups of insertion plates that are matched with the slots are arranged on the side wall of the positioning ring.

[0010] As a further solution of the utility model: the upper end of the slider is fixedly connected to the inner side wall of the positioning ring, and the positioning ring is movably arranged on the second pipe along the chute through the cooperation of the second nut and the slider with the screw rod.

[0011] Adopting the above technical solution:

[0012] The staff sleeved the partition on the end of the first pipe and the fixing ring on the end of the second pipe. When assembling and docking, the first pipe and the second pipe are brought closer to each other. Rotate the first pipe to rotate the insertion pipe arranged on one side of the partition into the fixing groove through the external thread cooperating with the internal thread. The cooperation of the internal thread and the external thread can tightly connect the insertion pipe and the fixing ring together. Then, a plurality of groups of threaded rods are penetrated through the partition and the fixing ring, and the first nut is arranged on one side of the partition and the fixing ring along the threaded rod to further fix the partition and the fixing ring. Through the above operations, the connection between the first pipe and the second pipe can be made more tight to avoid falling off, and the stability during use can be improved.

[0013] Before assembling the first pipe and the second pipe, the protective sleeve is sleeved on the surfaces of the first pipe and the second pipe. Since the protective sleeve is made of rubber material with high elastic performance, the protective sleeve can cover and cross over the positioning ring during the sleeving process. Rotate the second nut along the screw rod, and the second nut pushes the slider to move the positioning ring to one side of the protective sleeve along the chute. The insertion plates arranged on the side wall of the positioning ring are sequentially inserted into the corresponding slots to position the protective sleeve and make it stably arranged on the surface of the second pipe. Through the above operations, the replacement of the protective sleeve is relatively convenient, and the influence of the damage of the protective sleeve on the protection effect of the second pipe can be avoided.

[0032] Working principle: Before assembling the first pipe 1 and the second pipe 2, the protective sleeve 12 is sleeved on the surfaces of the first pipe 1 and the second pipe 2. Since the protective sleeve 12 is made of a rubber material with high elastic properties, the protective sleeve 12 can cover and pass over the positioning ring 18 during the sleeving process. Rotate the second nut 16 along the screw rod 15, and the second nut 16 pushes the slider 17 to move the positioning ring 18 to one side of the protective sleeve 12 along the chute 14. The insertion plates 19 provided on the side wall of the positioning ring 18 are inserted into the corresponding slots 13 in sequence to position the protective sleeve 12 and make it stably arranged on the surface of the second pipe 2. Through the above operations, the replacement of the protective sleeve 12 is relatively convenient, avoiding damage to the protective sleeve 12 and affecting the protection effect on the second pipe 2. The staff sleeved the partition plate 4 on the end of the first pipe 1 and the fixing ring 9 on the end of the second pipe 2. During docking and assembly, the first pipe 1 and the second pipe 2 are moved closer to each other, and the first pipe 1 is rotated to screw the insertion pipe 5 provided on one side of the partition plate 4 into the fixing groove 10 through the cooperation of the external thread 6 and the internal thread. The cooperation of the internal thread and the external thread 6 can tightly connect the insertion pipe 5 and the fixing ring 9 together. Then, a number of threaded rods 7 are passed through the partition plate 4 and the fixing ring 9, and the first nut 8 is arranged on one side of the partition plate 4 and the fixing ring 9 along the threaded rod 7 to further fix the partition plate 4 and the fixing ring 9. Through the above operations, the connection between the first pipe 1 and the second pipe 2 can be made more tight and avoid falling off, improving the stability during use.
