Description

Technical Field

[0001] The utility model relates to the technical field of urban drainage, in particular to a leakage-proof installation structure for municipal water supply and drainage. Background Art

[0002] Urban drainage is a drainage method in which urban sewage and rainwater are collected, transported, treated and discharged by the urban drainage system. Water is used in people's daily life and production activities. Water is polluted during use and becomes sewage, which needs to be treated and discharged. In addition, the runoff of precipitation (rainwater and melted ice and snow) in the city is large and should be discharged in time. The sources of urban drainage water are divided into domestic sewage, wastewater, industrial wastewater and rain and snow precipitation. The urban sewage drainage system usually refers to the drainage system that mainly collects and discharges domestic sewage, indoor drainage system and equipment. Various indoor (such as toilets, sewage pools, washbasins, etc.) and production workshop drainage equipment play the role of collecting sewage and wastewater, and they are the starting point of the entire drainage system. Domestic sewage and industrial wastewater flow into the sewage pipe system of the block (factory area, neighborhood or courtyard) through the indoor sewage pipe system such as water seal pipes, branch pipes, risers, trunk pipes and household pipes laid indoors.

[0003] At present, when urban drainage, that is, municipal water supply and drainage, is being constructed on the market, it is necessary to set up drainage pipes inside the municipal water supply and drainage system. In actual use, when setting up drainage pipes inside the municipal water supply and drainage system, the drainage pipes need to be connected to each other in pairs. However, most drainage pipes are connected in pairs using flanges and bolts. When the sealing ring in the flange between the two drainage pipes ages, it is necessary to rotate the bolts for disassembly and replacement. However, when the bolts are not rotated for a long time, rust and locking problems are prone to occur, which makes it difficult to replace the sealing ring in the flange between the two drainage pipes, and thus makes it easy for leakage to occur between the two drainage pipes.

[0024] In a preferred embodiment, a first spring 13 is provided between the limit column 8 and the disassembly groove 3, and a rotating rod 14 is fixedly connected to the outer wall of the disk 4. The rotating rod 14 passes through the outer wall of the connecting column 1 away from the end of the disk 4. When the limit column 8 moves, the limit column 8 can slide on the outer wall of the limit rod 7, so that the limit column 8 can drive the first spring 13 to move.

[0025] In a preferred embodiment, the rotating rod 14 is rotatably connected to the connecting column 1, and a second spring 15 is provided between the outer wall of the disk 4 and the disassembly groove 3. The two ends of the second spring 15 are respectively fixedly connected to the outer wall of the disk 4 and the inside of the disassembly groove 3. When the rotating rod 14 moves, the rotating rod 14 can drive the disk 4 to move, so that the disk 4 can drive the second spring 15 to move.

[0026] In a preferred embodiment, a connecting groove 16 is opened inside the connecting column 1 and is connected to the connecting groove 2. A sealing groove 17 is opened inside the connecting groove 2. When the disc 4 moves, the disc 4 drives the movable plate 5 to move, so that the movable plate 5 moves inside the disassembly groove 3.

[0027] The working principle of the utility model is as follows: when the device is used and the internal sealing ring 18 needs to be replaced in time, the rotating rod 14 is rotated at this time to make the rotating rod 14 rotate and move inside the disassembly groove 3, and the rotating rod 14 drives the disc 4 to move at the same time to make the disc 4 rotate and move inside the disassembly groove 3, and at the same time the disc 4 drives the second spring 15 to move, so that the second spring 15 itself is subjected to rotational distortion, and at the same time the disc 4 drives the movable plate 5 to move, so that the movable plate 5 makes a small circular motion inside the disassembly groove 3, and the movable plate 5 drives the roller 6 to move at the same time to make the roller 6 make a circular motion inside the disassembly groove 3, when the outer wall of the roller 6 contacts the outside of the pressure plate 10, at this time the movable plate 5 can drive the pressure plate 10 to move through the roller 6, so that the pressure plate 10 slides inside the disassembly groove 3, and the pressure plate 10 drives the movable plate 9 to move at the same time, so that the movable plate 9 slides inside the disassembly groove 3, and the movable plate 9 drives the limit column 8 to move at the same time. The column 8 slides inside the disassembly groove 3, and the limiting column 8 slides on the outer wall of the limiting rod 7 at the same time, so that the limiting column 8 can slide on the outer wall of the limiting rod 7, and the limiting column 8 can squeeze the first spring 13. At the same time, one end of the limiting column 8 can slide inside the connecting groove 2, so that one end of the limiting column 8 completely enters the disassembly groove 3. At this time, the pipeline 11 drives one end of the positioning hole 12 to enter the connecting groove 2. When the positioning hole 12 reaches one side of the limiting column 8, the rotating rod 14 is released at this time, and the torsion of the second spring 15 makes the subsequent roller 6 return to the initial position. At the same time, the first spring 13 loses the force from the pressure plate 10, causing the first spring 13 to drive the limiting column 8 back to the initial position, causing one end of the limiting column 8 to enter the positioning hole 12, making it convenient for the sealing ring 18 to be replaced in time inside, so as to prevent the sealing ring 18 between the two pipes 11 from being difficult to replace in the future, and the sealing ring 18 aging and leakage.

[0028] See also Figure 1 and Figure 3 The utility model provides a technical solution: a sealing ring 18 is engaged and connected inside the sealing groove 17, and a mounting groove 19 is opened between the sealing groove 17 and the connecting groove 2. When the movable plate 5 moves, the movable plate 5 can drive the roller 6 to move, so that the roller 6 can drive the pressure plate 10 to move.

[0029] In a preferred embodiment, the mounting groove 19 is respectively connected to the connecting groove 2 and the sealing groove 17. The cross-sectional shape of the connecting groove 2 is set to be circular. When the pressure plate 10 moves, the pressure plate 10 can drive the movable plate 9 to move, so that the movable plate 9 moves inside the disassembly groove 3.

[0030] The working principle of the utility model is as follows: when the device is used and the internal sealing ring 18 needs to be installed, firstly, the pipe 11 is moved out from the inside of the connecting groove 2 through the previous step, and then the aged sealing ring 18 is moved from the inside of the sealing groove 17 to the inside of the installation groove 19, and finally, the aged sealing ring 18 is moved from the inside of the installation groove 19 to the inside of the connecting groove 2, and the aged sealing ring 18 is moved out from the inside of the connecting groove 2, and at this time, a new sealing ring 18 is made to pass through the connecting groove 2 and enter into the inside of the installation groove 19, and the new sealing ring 18 is made to pass through the installation groove 19 to reach the inside of the sealing groove 17, and the new sealing ring 18 is made to expand inside the sealing groove 17, so that the sealing ring 18 inside the subsequent sealing groove 17 can be conveniently taken and installed.

[0031] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein by equivalents.
