Description

Technical Field

[0001] The utility model relates to the technical field of drainage, in particular to an overflow structure of a sewage standpipe on an overhead floor of a building. Background Art

[0002] In order to solve the problem of liquid overflowing from the main line when the main line is blocked, an overflow pipe is usually opened in the main line to discharge the liquid through the overflow pipe to avoid damage to the building caused by the blockage of the main line. If the elbow connecting the sewage riser and the horizontal main pipe is blocked, the sewage will overflow from the overflow pipe and will not flow back into the rooms of the owners on the lower floors. Routine inspections of the project can also discover and deal with it in time, thus requiring the use of the overflow structure of the sewage riser on the overhead floor of the building.

[0003] The existing overflow structure of the sewage riser on the overhead floor of a building has a complex installation structure between the sewage pipe and the overflow pipe, which is inconvenient to operate. It is difficult to quickly install and disassemble the sewage pipe and the overflow pipe, and the installation efficiency is low. In most cases, the overflow liquid directly enters the overflow pipe, and the impurities therein may clog the overflow pipe, thereby failing to achieve the purpose of drainage of the overflow pipe. Therefore, in view of the above problems, an overflow structure of the sewage riser on the overhead floor of a building is proposed. Utility Model Content

When the sewage pipe 1 is blocked, the overflow liquid enters the installation pipe section 2 and the overflow pipe section 3. The water pressure of the overflow liquid pushes the overflow baffle 8 to rotate. Because the overflow baffle 8 is rotatably installed on the inner wall surface of the overflow pipe section 3 through the rotating shaft 7, when the water pressure of the liquid entering the overflow pipe 3 is large, the overflow baffle 8 can be pushed to rotate, so that the conduction port of the overflow baffle 8 connecting the overflow pipe section 3 is enlarged, and the resistance encountered by the overflow liquid during discharge is reduced, so that the overflow liquid can be quickly discharged through the overflow pipe 3. When the sewage pipe 1 is not blocked, the water pressure of the overflow liquid is small, and the overflow baffle 8 is restored to its original position by the pull of the return spring 10, that is, the overflow pipe 3 port is blocked, so that the overflow liquid no longer continues to flow out.

[0024] Among them, a positioning groove 11 is opened on one side of the interior of the mounting tube 2, and a positioning block 12 is fixedly connected to the surface of the overflow tube 3, and the positioning block 12 is inserted into the interior of the positioning groove 11. A sealing ring 13 is fixedly connected to one end of the overflow tube 3, and the positioning block 12 is inserted into the interior of the positioning groove 11, so as to achieve the purpose of accurately positioning the card slot 41 and the card rod 44, and can facilitate the accurate insertion of the card rod 44 into the interior of the card slot 41. The setting of the sealing ring 13 can make the overflow tube 3 and the mounting tube 2 sealed to prevent leakage.

[0025] The filter mechanism 6 includes a fixing frame 61 . The fixing frame 61 is placed on one side of the interior of the mounting groove 5 . A filter plate 62 is fixedly connected to the interior of the fixing frame 61 .

[0026] Among them, a pull ring 63 is fixedly connected to one side of the filter plate 62, and a protrusion 64 is fixedly connected to the inner surface of the mounting tube 2. The protrusion 64 is located on one side of the inner part of the mounting groove 5. Impurities in the overflow liquid are filtered through the filtering mechanism 6 to prevent the impurities from clogging the overflow pipe 3. During filtering, the overflow liquid is filtered through the filter plate 62 in the fixed frame 61, and then enters the interior of the overflow pipe 3, thereby achieving the purpose of filtering impurities in the overflow liquid. Long-term filtration causes impurities to clog the filter plate 62, so that the filter plate 62 and the fixed frame 61 are pulled out of the mounting tube 2 through the pull ring 63. After the filter plate 62 is cleaned or replaced with a new filter plate 62, the fixed frame 61 is pushed by hand so that the fixed frame 61 is squeezed into one side of the protrusion 64, so that the filter plate 62 is fixed, thereby completing the cleaning or replacement of the filter plate 62.

[0027] The mounting mechanism 4 includes a slot 41 , which is opened on the surface of the overflow pipe 3 , a mounting shell 42 is fixedly connected to the surface of the mounting pipe 2 , and a slide plate 43 is slidably connected inside the mounting shell 42 .

[0028] Among them, the two sides of the slide plate 43 are fixedly connected with a clamping rod 44, one end of the clamping rod 44 passes through the inner wall of the mounting tube 2 and is clamped in the inside of the clamping groove 41, the other end of the clamping rod 44 passes through the inner wall of the mounting tube 2 and is fixedly connected with a handle 45, and the clamping rod 44 is slidably connected to the inner wall of the mounting shell 42.

[0029] Among them, the outer sleeve of the clamping rod 44 is provided with a locking spring 46, which is located inside the mounting shell 42, and the locking spring 46 is located on the top side of the slide plate 43. One end of the overflow pipe 3 is inserted into the inside of the mounting groove 5, and the positioning block 12 is inserted into the inside of the positioning groove 11, so as to accurately position the slot 41 and the clamping rod 44, and can facilitate the accurate insertion of the clamping rod 44 into the inside of the slot 41. The setting of the sealing ring 13 can make the overflow pipe 3 and the mounting tube 2 sealed to prevent leakage. Under the push of the locking spring 46, one end of the clamping rod 44 is clamped with the slot 41, so that the overflow pipe 3 and the mounting tube 2 are installed. When disassembling, pull the handle 45 outward, and the handle 45 drives the slide plate 43 to slide upward inside the mounting shell 42. At the same time, the slide plate 43 drives one end of the clamping rod 44 to disengage from the slot 41, and then the overflow pipe 3 is taken out of the mounting tube 2.

[0030] Working principle: when the sewage pipe 1 is not blocked, liquid enters the installation pipe section 2. At this time, since the installation pipe section 2 is tilted upward, the liquid can flow back into the sewage pipe 1. When the sewage pipe 1 is blocked, the overflow liquid enters the installation pipe section 2 and enters the overflow pipe section 3. The water pressure of the overflow liquid pushes the overflow baffle 8 to rotate. Because the overflow baffle 8 is rotatably installed on the inner wall surface of the overflow pipe section 3 through the rotating shaft 7, when the water pressure of the liquid entering the overflow pipe 3 is large, the overflow baffle 8 can be pushed to rotate, so that the conduction port of the overflow baffle 8 to the overflow pipe section 3 is enlarged, and the resistance encountered by the overflow liquid during discharge is reduced, so that the overflow liquid can be quickly discharged through the overflow pipe 3. When the sewage pipe 1 is not blocked, the water pressure of the overflow liquid is small, and the overflow baffle 8 is restored to its original position by the pull of the return spring 10, that is, the overflow pipe 3 is blocked, so that the overflow liquid no longer continues to flow out.

[0031] When the overflow liquid passes through the installation pipe 2, the impurities in the overflow liquid are filtered by the filter mechanism 6 to prevent the impurities from clogging the overflow pipe 3. During the filtration, the overflow liquid is filtered by the filter plate 62 in the fixed frame 61, and then enters the interior of the overflow pipe 3, thereby achieving the purpose of filtering the impurities in the overflow liquid. The long-term filtration causes the impurities to clog the filter plate 62, so the filter plate 62 and the fixed frame 61 are pulled out of the installation pipe 2 through the pull ring 63, and after the filter plate 62 is cleaned or replaced with a new filter plate 62, the fixed frame 61 is pushed by hand so that the fixed frame 61 is squeezed into one side of the protrusion 64, so that the filter plate 62 is fixed, and the cleaning or replacement of the filter plate 62 is completed. The operation is convenient and quick, and the filtering effect of the filter plate 62 is guaranteed.

[0032] When installing between the mounting pipe 2 and the overflow pipe 3 through the mounting mechanism 4, first insert one end of the overflow pipe 3 into the interior of the mounting groove 5, and at the same time insert the positioning block 12 into the interior of the positioning groove 11, so as to achieve the purpose of accurately positioning the card slot 41 and the card rod 44, and it is convenient to accurately insert the card rod 44 into the interior of the card slot 41, and the setting of the sealing ring 13 can make the overflow pipe 3 and the mounting pipe 2 seal to prevent leakage. Under the push of the tightening spring 46, one end of the card rod 44 is engaged with the card slot 41, so that the overflow pipe 3 and the mounting pipe 2 are installed. When disassembling, pull the handle 45 outward, the handle 45 drives the slide plate 43 to slide upward inside the mounting shell 42, and at the same time the slide plate 43 drives one end of the card rod 44 to disengage from the card slot 41, and then take the overflow pipe 3 out of the mounting pipe 2. The setting of the mounting mechanism 4 can facilitate the installation and disassembly between the sewage pipe 1 and the overflow pipe 3, and the operation is simple, convenient and fast.
