Description

Technical Field

[0001] The utility model relates to the technical field of drainage devices, in particular to an anti-blocking device for a main vertical pipe of residential sewage. Background Art

[0002] As the main channel for sewage discharge of the entire building, the main riser of residential sewage carries all kinds of sewage generated in daily life. However, it often encounters some challenges during use. Among them, kitchen grease is a common problem. If the grease generated during daily cooking is not properly handled, it can easily enter the main riser of sewage with the water flow. These greases gradually accumulate in the pipe, gradually harden, and may eventually form a blockage.

[0003] In addition to kitchen grease, bathroom debris is another major cause of main riser blockage. In daily life, some non-degradable items, such as sanitary napkins and wet wipes, are mistakenly thrown into the toilet and flow into the sewage pipe with the water. These debris entangle with each other in the pipe, forming obstacles, gradually causing poor water flow and eventually causing blockage.

[0004] When the bottom of the main riser is clogged, sewage cannot be discharged normally and will look for other ways out. Since the indoor floor drains or toilets of low-rise residents are directly connected to the sewage pipes, the sealing of these places is relatively poor, so they become the first choice for sewage overflow. When sewage overflows from the indoor floor drains or toilets of low-rise residents, it not only brings great inconvenience to the residents, but also causes damage to their property. Furniture, floors, walls, etc. may be eroded by sewage, and even some valuables may be damaged. Summary of the invention

[0017] The utility model is further described below in conjunction with the accompanying drawings and specific implementation methods.

[0018] like Figure 1 and 3 As shown, the utility model includes a main vertical pipe 1, an overflow pipe 6, an inclined pipe 4, a drain pipe 7 and a rotating mechanism 3.

[0019] The main riser 1 is located underground and is connected to the first connecting pipe 2 through a three-way joint. The first connecting pipe 2 is arranged vertically with the main riser 1. An inlet pipe 401 is provided at one end of the inclined pipe 4, and an outlet pipe 402 is provided at the other end. The inlet pipe 401 and the outlet pipe 402 are arranged in parallel. The inclined pipe 4 is arranged obliquely between the inlet pipe 401 and the outlet pipe 402.

[0020] The water inlet pipe 401 of the inclined pipe 4 is rotatably matched with the joint of the first connecting pipe 2, the water inlet pipe 401 is inserted into the tube cavity of the first connecting pipe 2, and a sealing ring is installed between the water inlet pipe 401 and the tube cavity wall of the first connecting pipe 2. The water outlet pipe 402 of the inclined pipe 4 is connected with one end of the overflow pipe 6 through the electromagnetic flowmeter 5, and the other end of the overflow pipe 6 is connected with the water inlet pipe 401 of the inclined pipe 4, the water outlet pipe 402 of the inclined pipe 4 is rotatably matched with the second connecting pipe 8, the water outlet pipe 402 of the inclined pipe 4 is inserted into the tube cavity of the second connecting pipe 8, and a sealing ring is installed between the water inlet pipe 401 and the tube cavity wall of the second connecting pipe 8, the second connecting pipe 8 is connected with the drain pipe 7 through the elbow pipe fitting, and the second connecting pipe is arranged vertically with the drain pipe 7. The first connecting pipe 2 and the second connecting pipe are located on the same axis.

[0021] The lower ends of the main riser 1 and the drainage pipe 7 are connected to an underground sewage well.

[0022] In the optimization scheme, the overflow pipe 6 is connected to the sewage pipe 601, and the sewage pipe 601 is vertically arranged to the overflow pipe 6. A sealing cover 602 is installed at the outlet position of the sewage pipe 601. The outer wall of the sewage pipe 601 is provided with an external thread, and the sealing cover 602 is provided with an internal thread. The sealing cover 602 is threadedly matched with the sewage pipe 601.

[0023] like Figure 2 As shown, the first connecting pipe 2 is connected to the inclined pipe 4 through a rotating mechanism 3, and the rotating mechanism 3 includes a fixed housing 302, a gear 303, a rack 305 and a telescopic rod 301. The fixed housing 302 is provided with a through hole, and the first connecting pipe 2 passes through the through hole on the fixed housing 302 and is fixedly connected thereto. The fixed housing 302 is provided with a cavity, and the gear 303 and the rack 305 are installed in the cavity of the fixed housing 302. The gear 303 is fixedly connected to the water inlet pipe 401 of the inclined pipe 4.

[0024] The two side walls of the fixed shell 302 are respectively provided with slide holes, which are connected with the cavity of the fixed shell 302 . The rack 305 passes through the slide holes of the fixed shell 302 and meshes with the gear 303 . The rack 305 slides with the side walls of the fixed shell 302 .

[0025] In the optimized solution, slideways are respectively provided on the two side walls of the cavity of the fixed shell 302, and sliding blocks are respectively provided on the two side walls of the rack 305, and the sliding blocks are slidably matched with the slideways.

[0026] The upper end of the fixed housing 302 is fixedly mounted with a telescopic rod 301, the inner rod of the telescopic rod 301 is connected to the connecting rod 306 through the connecting plate 304, and the connecting rod 306 is connected to the rack 305. When the telescopic rod 301 is retracted, the inner rod drives the connecting rod 306 to move through the connecting plate 304, the connecting rod 306 drives the rack 305 to move, the rack 305 drives the gear 303 to rotate, and the gear 303 drives the tilting tube 4 to rotate.

[0027] In the optimized solution, the telescopic rod 301 is an electric telescopic rod.

[0028] In this embodiment, the electromagnetic flowmeter 5 is connected to the alarm and the telescopic rod 301 through a circuit. The circuit is a prior art and its specific structure is not described in detail. When sewage flows through the electromagnetic flowmeter 5, the signal is transmitted to the alarm and the telescopic rod 301 respectively. The alarm sounds an alarm to remind the administrator to find the main riser 1 blocked in time and clear the pipeline in advance to avoid property losses to the residents on the lower floors. The signal sent by the electromagnetic flowmeter 5 causes the telescopic rod 301 to shrink.

[0029] The operation process is as follows: Under normal conditions, the overflow pipe 6 is located above the first connecting pipe 2 and the second connecting pipe. When sewage flows through the main vertical pipe 1, since the overflow pipe 6 is higher than the first connecting pipe 2, the sewage flows into the underground sewage well through the main vertical pipe 1, and does not flow into the overflow pipe 6 through the first connecting pipe 2. When the main vertical pipe 1 is blocked, the sewage flows into the overflow pipe 6 through the inclined pipe 4, and finally enters the underground sewage well through the drainage pipe 7. When the sewage flows into the overflow pipe 6, it enters the electromagnetic flowmeter 5, and the electromagnetic flowmeter 5 transmits the sensed signal to the alarm, which sounds an alarm to remind the administrator to find the blockage of the main vertical pipe 1 in time and dredge the pipe in advance to avoid property losses to low-level residents. When the signal is transmitted to the electric telescopic rod 301, the telescopic rod 301 contracts, the inner rod drives the connecting rod 306 to move through the connecting plate 304, the connecting rod 306 drives the rack 305 to move, the rack 305 drives the gear 303 to rotate, the gear 303 drives the inclined pipe 4 to rotate, the inclined pipe 4 drives the overflow pipe 6 to rotate 180°, so that the overflow pipe 6 rotates to the bottom of the inclined pipe 4, so that the sewage can flow into the underground sewage well. Since the overflow pipe 6 is lower than the water inlet pipe 401 and the water outlet pipe 402 of the two inclined pipes 4 after rotating 180°, some impurities in the sewage will gather in the overflow pipe 6. At this time, the sewage pipe 601 can be opened to discharge the impurities therein to prevent them from clogging the overflow pipe 6.

[0030] It should be noted that the specific embodiments of the present invention have been described in detail. For those skilled in the art, various obvious changes to the present invention without departing from the spirit and scope of the present invention are within the protection scope of the present invention.
