Description

Technical Field

[0001] The utility model relates to the field of environmental management, in particular to water body management equipment. Background Art

[0002] During the rainy season, rainwater mixes with sewage and becomes sewage, which pollutes the city and surrounding environment and is not conducive to the sustainable use of water resources. Utility Model Content

[0003] In order to solve the above technical problems, the utility model provides the following technical solutions: a rainwater and sewage diversion device, including a box body and a float lever mechanism arranged in the box body, the box body is provided with a water inlet, a rainwater outlet and a sewage outlet, the rainwater outlet is located on the opposite side of the water inlet, the sewage outlet is located below the rainwater outlet, a sewage valve is provided at the sewage outlet, the float lever mechanism can open and close the sewage valve according to the water level, a rainwater siphon port is provided on the box body, the rainwater siphon port is equipped with a siphon pipe, and the curved part at the high end of the siphon pipe is at the same height as the bottom of the rainwater outlet.

[0004] When the rain begins, the water volume at the water inlet increases, the rainwater level in the box rises, the float of the float lever mechanism rises, and the float closes the drain valve through the lever principle. When the rainwater level rises to the rainwater outlet, the rainwater begins to be discharged into the municipal rainwater pipe network.

[0005] After the rain stops, the water volume at the water inlet decreases, and the rainwater level in the box drops. When the level drops to the bottom of the rainwater outlet, the rainwater level stops dropping. At this time, the float lever mechanism cannot fully open the drain valve (if the rainwater outlet is lowered, the rainwater and sewage diversion effect is not good). The siphon tube continues to siphon rainwater for drainage. When the rainwater level drops to the bottom of the siphon tube, the float lever mechanism can fully open the drain valve, and the sewage and trapped pollutants in the box are discharged into the municipal sewage network through the drain valve and the sewage outlet.

[0006] The utility model is provided with a siphon pipe, which effectively meets the requirement of complete rainwater and sewage diversion. The rainwater and sewage diversion device provided with a siphon pipe effectively solves the problem of rainwater and sewage mixing together during the rainy season, and can also reduce the pollution of sewage to the environment, protect water resources, and facilitate their sustainable use.

[0007] A sewage drain tank is set at the sewage outlet, the sewage drain tank is located in the box, and the sewage drain valve is set above the sewage drain tank. Sewage and pollutants enter the sewage drain tank through the sewage drain valve, and then are discharged into the municipal sewage pipe network through the sewage outlet.

[0008] The float lever mechanism includes a float, a float adjustment rod connected to the float, a swing arm connected to the float adjustment rod, a push-pull rod connected to the swing arm, and a flip door connected to the push-pull rod. One end of the flip door is hinged on a support beside the drain valve. The swing arm is pivoted on a support rod, and the support rod is fixed on the box. When the rainwater level in the box rises, the float rises at the same time. The float drives the float adjustment rod, the swing arm, and the push-pull rod through the lever principle to close the drain valve. The higher the rainwater level rises, the greater the water pressure on the flip door, and the tighter the flip door is closed. When the rainwater level in the box drops, the float drops at the same time. When the rainwater level drops to the bottom of the siphon, the float can fully open the drain valve through the lever principle.

[0009] A rainwater pipe is installed in the box, and the rainwater pipe is located between the water inlet and the rainwater outlet, and the rainwater pipe is at the same height as the rainwater outlet. The rainwater pipe is located in the middle of the box. When the rainwater in the box overflows the rainwater pipe, the sediment in the rainwater sinks to the bottom of the rainwater pipe, and the floating objects and light pollutants float on the top of the rainwater pipe. Therefore, the rainwater pipe effectively traps the sediment, floating objects and light pollutants in the rainwater in the box, ensuring that the rainwater discharged into the municipal rainwater pipe network is relatively clean.

[0010] A grille basket is provided in the box body, and the grille basket is located below the water inlet. Rainwater enters the box body through the water inlet, and the rainwater is filtered by the grille basket, and large particles in the rainwater are intercepted in the grille basket.

[0022] Combination Figure 1 , Figure 2 A rainwater-sewage diversion device comprises a box body 10 and a float lever mechanism arranged in the box body. A water inlet 11, a rainwater outlet 12 and a sewage outlet 13 are arranged on the box body. The rainwater outlet is located on the opposite side of the water inlet, and the sewage outlet is located below the rainwater outlet. A sewage valve 14 is arranged at the sewage outlet. The float lever mechanism can open and close the sewage valve according to the water level. A rainwater siphon port 15 is arranged on the box body. The rainwater siphon port is equipped with a siphon pipe 20. The curved part at the high end of the siphon pipe is at the same height as the bottom of the rainwater outlet.

[0023] like Figure 2 When the rain starts, the water volume at the water inlet 11 increases, the rainwater level in the box 10 rises, the float 30 of the float lever mechanism rises, and the float closes the drain valve 14 through the lever principle. When the rainwater level rises to the rainwater outlet 12, the rainwater begins to be discharged into the municipal rainwater pipe network.

[0024] After the rain stops, the water volume at the water inlet 11 decreases, and the rainwater level in the box 10 drops. When the level drops to the bottom of the rainwater outlet 12, the rainwater level stops dropping. At this time, the float lever mechanism cannot fully open the drain valve 14. The siphon pipe 20 continues to siphon rainwater for drainage. Figure 1 When the rainwater level drops to the bottom of the siphon 20, the float lever mechanism can fully open the drain valve 14, and the sewage and trapped pollutants in the box 10 are discharged into the municipal sewage network through the drain valve 14 and the sewage outlet 13.

[0025] like Figure 2 A sewage outlet 13 is provided with a sewage tank 16, which is located in the box 10, and a sewage valve is provided above the sewage tank. Sewage and pollutants enter the sewage tank 16 through the sewage valve 14, and then are discharged into the municipal sewage pipe network through the sewage outlet 13.

[0026] like Figure 1 The float lever mechanism includes a float 30, a float adjustment rod 31 connected to the float, a swing arm 32 connected to the float adjustment rod, a push-pull rod 33 connected to the swing arm, and a flip door 34 connected to the push-pull rod. One end of the flip door is hinged on a support beside the drain valve 14, the swing arm is pivotally connected to the support rod, and the support rod is fixed to the box body 10.

[0027] The rainwater level in the box 10 rises, and the float 30 rises at the same time. The float drives the float adjustment rod 31, the swing arm 32, and the push-pull rod 33 through the lever principle, so that the flip door 34 closes the drain valve 14. The higher the rainwater level rises, the greater the water pressure on the flip door 34, and the tighter the flip door is closed. The rainwater level in the box 10 drops, and the float 30 drops at the same time. When the rainwater level drops to the bottom of the siphon 20, the float can completely open the drain valve through the lever principle.

[0028] A rainwater pipe 30 is provided in the box body 10, and the rainwater pipe is located between the water inlet 11 and the rainwater outlet 12, and the rainwater pipe and the rainwater outlet are at the same height. A grille basket 40 is provided in the box body 10, and the grille basket is located below the water inlet 11.

[0029] A pair of vertical plates and a horizontal plate are provided in the box body. The horizontal plate is installed on the inner wall of the box body 10 and a vertical plate. The rainwater pipe 30 is installed between the pair of vertical plates. The parts of the pair of vertical plates located below the horizontal plate are connected. Rainwater enters the box body 10 through the water inlet 11, and the rainwater is filtered by the grille basket 40. Large particles in the rainwater are trapped in the grille basket. When the rainwater in the box body 10 overflows the rainwater pipe 30, the sediment in the rainwater sinks to the bottom of the rainwater pipe, and floating objects and light pollutants float on the top of the rainwater pipe. In this way, the rainwater pipe 30 effectively ensures that the sediment, floating objects and light pollutants in the rainwater are trapped in the box body 10, ensuring that the rainwater discharged into the municipal rainwater pipe network is relatively clean.
