Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of sewage diversion, in particular to a rainwater and sewage diversion structure for old communities. Background Technique
[0002] Residents in old communities discharge some domestic sewage and wastewater into the rainwater pipes. These sewage and wastewater finally flow into the community rainwater pipe network, causing blockage and water environmental pollution. The building rainwater riser actually becomes a rain-sewage combined pipe. Therefore, a large number of old communities are now implementing the transformation of rain-sewage diversion in the community. There are at least the following disadvantages in the existing drainage process of old communities:
[0003] 1. In the existing drainage process of old communities, rainwater and sewage cannot be discharged separately. A large amount of water flowing into the sewage pipe will waste the resources of the sewage treatment plant.
[0004] 2. In the existing drainage process of old communities, rainwater will drive impurities to block the rainwater pipe, affecting the discharge of rainwater. Therefore, we introduce a rainwater and sewage diversion structure for old communities. Content of the Utility Model
[0005] The main purpose of the utility model is to provide a rainwater and sewage diversion structure for old communities, which can effectively solve the problems in the background technique.
[0006] To achieve the above purpose, the technical solution adopted by the utility model is:
[0007] A rainwater and sewage diversion structure for old communities includes a rainwater diversion pipe. A manhole cover is arranged at the upper end of the rainwater diversion pipe. Rainwater pipes are fixedly connected to both sides of the middle part of the rainwater diversion pipe, and the interiors of the rainwater pipes and the rainwater diversion pipe are interconnected. A sewage pipe is fixedly connected to the lower end of the rainwater diversion pipe, and the interior of the sewage pipe and the rainwater diversion pipe are interconnected. A dirt outlet is opened at the upper part of the front end of the rainwater diversion pipe, and a dirt inlet is opened at the lower part of the front end of the rainwater diversion pipe. A filtering mechanism is commonly arranged at the dirt outlet and the dirt inlet. A diversion mechanism is arranged inside the rainwater diversion pipe.
[0008] Preferably, the diversion mechanism includes a diversion plate. The diversion plate is fixedly connected to the inner wall of the rainwater diversion pipe. A flow-limiting hole is opened in the middle of the diversion plate. A clamping groove is arranged at the lower end of the flow-limiting hole, and the cross-section of the clamping groove is spherical. The flow-limiting hole and the clamping groove penetrate through the diversion plate.
[0009] Preferably, a floating ball is arranged above the diversion plate. Four support rods are fixedly connected to the lower side of the outer surface of the floating ball. A connecting column is fixedly connected to the middle part of the lower side of the floating ball. The connecting column is inserted into the flow-limiting hole, and a clamping ball is fixedly connected to the lower end of the connecting column.
[0010] Preferably, the locking ball is matched with the locking groove, the locking ball is locked with the flow limiting hole through the locking groove, and the diameter of the connecting column is smaller than the diameter of the flow limiting hole.
[0011] Preferably, the filtering mechanism includes a filter frame and a connecting chamber, the filter frame is fixedly connected to the inner wall of the rainwater diversion pipe, a filter net is fixedly installed inside the filter frame, the connecting chamber is fixedly connected to the sewage outlet, a sewage pipe is fixedly connected to the front end of the connecting chamber, and the sewage pipe is fixedly connected to the sewage inlet.
[0012] Preferably, the filter screen is matched with the waste outlet, and the sewage pipe is communicated with the interior of the sewage pipe through the waste inlet.
[0013] Compared with the prior art, the utility model has the following beneficial effects:
[0014] 3. Through the setting of filtering mechanism, in the process of rainwater discharge, the manhole cover will initially block large debris in the rainwater, and the rainwater will be filtered through the filter net. The dirt after filtering and blocking will easily slide from the inclined filter net, and the dirt will enter the sewage pipe through the dirt outlet, connecting bin, sewage pipe and dirt inlet. The dirt will be discharged from the sewage pipe for centralized treatment, so that the debris in the rainwater will not block the rainwater pipe, which improves the quality of rainwater and sewage diversion.
[0015] 4. Through the diversion mechanism set up, the filtered rainwater will enter the diversion mechanism for diversion. The gap between the flow limiting hole and the connecting column can flow rainwater. Since the gap between the flow limiting hole and the connecting column is small, the discharge speed of rainwater is limited. When the rainfall is large, the flow limiting hole will not be able to discharge in time, which will cause the water level above the diversion plate to rise. The rising water surface will float the floating ball so that the card ball will block the card slot. At this time, the liquid level will be higher than the rainwater pipe and the rainwater will be discharged from the rainwater pipe. This device can flow appropriate rainwater into the sewage pipe without causing processing pressure on the sewage treatment plant. However, when the rainwater is too heavy, it will cause the rainwater to flow out of the rainwater pipe, and use filtration to avoid blockage during the diversion process, to ensure stable diversion of rainwater and sewage, and to ensure that the resources of the sewage treatment plant will not be wasted.

The dirt will enter the sewage pipe (4) through the dirt outlet (7), the connection chamber (53), the sewage pipe (54) and the dirt inlet (8). The dirt will be discharged from the sewage pipe (4) for centralized treatment.
[0027] In this embodiment, the diverter mechanism 6 includes a diverter plate 61, which is fixedly connected to the inner wall of the rainwater diverter pipe 1.

The blocked dirt will easily slide from the inclined filter net (52), and the dirt will enter the sewage pipe (4) through the dirt outlet (7), the connecting chamber (53), the sewage pipe (54) and the dirt inlet (8). The dirt will be discharged from the sewage pipe (4) for centralized treatment. Through the provided diversion mechanism (6), the floating ball (66) has the buoyancy to drive the blocking function of the stuck ball (64). The floating ball (66) is supported by four support rods (67). The flow-limiting hole (62) is supported on the diversion plate (61) to maintain the flowability of the flow-limiting hole (62). The cross-sectional spherical clamping groove (63) and the clamping ball (64) have good sealing performance. The filtered rainwater will enter the diversion mechanism (6) for diversion. The gap between the flow-limiting hole (62) and the connecting column (65) can flow rainwater. Since the gap between the flow-limiting hole (62) and the connecting column (65) is small, the discharge speed of rainwater is limited. When the rainfall is large, the flow-limiting hole (62) cannot be discharged in time, which will cause the water surface above the diversion plate (61) to rise. The rising water surface will float the floating ball (66) so that the clamping ball (64) blocks the clamping groove (63). At this time, the liquid level will be higher than the rainwater pipe (3) and the rainwater will be discharged from the rainwater pipe (3).
