Description

Technical Field

[0001] The present application relates to the field of municipal pipe networks, and in particular to a rainwater and sewage diversion well structure. Background Art

[0002] In residential communities, rainwater wells are common facilities. Their main function is to carry rainwater discharged from residential buildings and discharge it into nearby rivers through rainwater pipes. In actual use, since rainwater pipes are usually set on one side of the balcony of a building, residents often discharge the waste water from washing machines into rainwater wells through rainwater pipes, which results in a large amount of domestic water being discharged directly into the river without being treated. Utility Model Content

[0003] In order to reduce the probability of domestic water being discharged directly into the river through the rainwater well, the present application provides a rainwater and sewage diversion well structure.

[0004] The present application provides a rainwater and sewage diversion well structure, which adopts the following technical solutions:

[0005] A rainwater and sewage diversion well structure comprises a rainwater well, an inlet pipe connected to the rainwater well and a drain pipe connected to the rainwater well, wherein a weir wall is arranged in the rainwater well and an electrically controlled valve is arranged at the weir wall; the weir wall divides the bottom space of the rainwater well into an inlet chamber connected to the inlet pipe and a drain chamber connected to the drain pipe; a drainage pipe connected to a sewage well is connected to the top of the rainwater well, and a lifting pump for pumping water in the inlet chamber into the drainage pipe is also arranged in the inlet chamber; the rainwater and sewage diversion well structure is also provided with a rain gauge and a controller; the rain gauge, the lifting pump and the electrically controlled valve are all electrically connected to the controller.

[0006] By adopting the above technical solution, when the rain gauge does not detect rain, the controller controls the electric control valve to be in a closed state. At this time, the domestic water discharged from the residential community into the rainwater well will be blocked by the weir wall, and the domestic water in the water inlet cavity can also be input into the sewage well through the lifting pump, so that this part of the domestic water will not be directly discharged into the river through the rainwater well, reducing the probability of domestic water being directly discharged into the river through the rainwater well. When the rain gauge detects rain, the controller controls the electric control valve to open. At this time, the rainwater discharged from the water inlet pipe into the rainwater well can pass through the electric control valve and be discharged into the river through the drainage pipe.

[0007] Optionally, the height of the weir wall is less than the depth of the rainwater well.

[0008] By adopting the above technical solution, rainwater can also enter the drainage cavity through the top of the weir wall, and then be discharged into the river through the drainage pipe, thereby being able to cope with the situation where the electric control valve fails and is always closed, and can also cope with the situation when the rainfall is heavy and the flow rate of rainwater at the electric control valve is less than the flow rate discharged into the rainwater well through the water inlet pipe.

[0009] Optionally, a filter screen cover is further provided at the front end of the electric-controlled valve, and the filter screen cover covers the water inlet of the electric-controlled valve.

[0010] By adopting the above technical solution, the filter screen can filter the water entering the electric control valve, and is used to filter some larger garbage such as leaves, garbage bags, etc., to reduce the impact of these garbage on the opening and closing of the electric control valve.

[0011] Optionally, the filter screen cover includes a filter screen portion for passing water and an isolation portion for isolating deposited silt, and the filter screen portion is located on an upper side of the isolation portion.

[0012] By adopting the above technical solution, since a part of fine sand will be deposited at the bottom of the rainwater well when rainwater and domestic water are circulated, the setting of the isolation part in the filter screen can prevent the accumulation of fine sand in front of the water inlet of the electric control valve, reduce the probability of fine sand directly entering the electric control valve, and help to extend the service life of the electric control valve.

[0013] Optionally, the electrically controlled valve is provided with a first flange, the filter screen cover has a second flange matching with the first flange, and the first flange and the second flange are connected by a bolt and nut structure.

[0014] By adopting the above technical solution, a mounting structure for mounting the filter screen cover on the electric control valve is specifically disclosed. By adopting the above mounting structure, the installation is convenient and the installation strength is high.

[0015] Optionally, the horizontal distance from the weir wall to the drainage pipe is smaller than the distance from the weir wall to the water inlet pipe.

[0016] By adopting the above technical solution, the distance from the weir wall to the water inlet pipe can be controlled, which helps to reduce the probability of domestic water or rainwater directly impacting the electric control valve and helps to extend the service life of the electric control valve.

[0017] Optionally, a liquid level meter is further provided in the water inlet chamber, and the liquid level meter is electrically connected to the controller.

[0018] By adopting the above technical solution, the liquid level height in the water inlet chamber can be detected by the liquid level meter, and then a preset value can be set in the controller. When the liquid level height in the water inlet chamber exceeds the preset value, the lifting pump is turned on to discharge the domestic sewage in the water inlet chamber into the sewage well, which helps to discharge the rainwater in the water inlet chamber into the sewage well in time.

[0019] Optionally, there are two lifting pumps in the rainwater well.

[0020] By adopting the above technical solution, two lifting pumps are installed in the rainwater well, so that one can be used and the other can be kept as a backup. When one of the lifting pumps in use fails, the other lifting pump can be used to discharge domestic sewage into the sewage well.

[0021] Optionally, a mounting base is provided at the bottom of the water inlet chamber, and the two lifting pumps are installed on the mounting base.

[0022] By adopting the above technical solution, the setting of the mounting base can improve the installation stability of the lifting pump and reduce the probability of the lifting pump tipping over in the rainwater well.

[0023] In summary, the present application includes at least one of the following beneficial technical effects:

[0024] A rainwater and sewage diversion well structure is provided in which a weir wall, an electric control valve, a lifting pump and a drainage pipe are arranged in the rainwater well. When it is not raining, the electric control valve is closed, and the domestic sewage flowing into the rainwater well can be transported to the sewage well through the lifting pump; when it is raining, the electric control valve is opened, and the rainwater flowing into the rainwater well can pass through the electric control valve and the drainage pipe into the river, thereby reducing the probability of domestic water being directly discharged into the river through the rainwater well;

[0025] By setting a filter screen at the water inlet of the electric control valve, the probability of large garbage affecting the opening and closing of the electric control valve can be reduced, and the filter screen is designed to be a filter screen part located on the upper side and an isolation part located on the lower side, which can also prevent the sediment deposited in the rainwater well from affecting the electric control valve, which helps to extend the service life of the electric control valve;

[0026] By setting a liquid level meter electrically connected to the controller and detecting the liquid level height in the water inlet chamber, the start of the lift pump is controlled, which helps to discharge rainwater in the water inlet chamber into the sewage well in time.

The inlet chamber 11 is connected to the inlet pipe 2, and the drainage chamber 12 is connected to the drainage pipe 3. The height of the weir wall 4 is lower than the depth of the rainwater well 1, so that a gap for rainwater to pass through is formed above the weir wall 4. The horizontal distance from the weir wall 4 to the drainage pipe 3 is smaller than the distance from the weir wall 4 to the inlet pipe 2. In this embodiment, the horizontal distance from the weir wall 4 to the drainage pipe 3 is 1 / 3 of the distance from the weir wall 4 to the inlet pipe 2.
