When the rain and sewage diversion device works, the rainwater flowing into the rain and sewage well 10 can be discharged by the drain pipe 20, and the sewage flowing into the rain and sewage well 10 can be discharged by the drain pipe 30. It should be noted that the density and surface viscosity of the rainwater and the sewage are different, wherein the sewage in this embodiment is methanol or an oil substance.
In this embodiment, the rain and sewage diversion device of this embodiment further includes a closing-in tank 40, a first floating ball assembly 50 and a second floating ball assembly 60, where the closing-in tank 40 is installed at the wellhead position of the rain and sewage well 10, so as to receive the rain water or sewage flowing into the rain and sewage well 10.
The tank bottom 41 of the closing tank 40 of the embodiment is connected and communicated with a flow-throwing pipe 70, the flow-throwing pipe 70 can guide rainwater flowing into the closing tank 40 to the first floating ball assembly 50, guide sewage led into the closing tank 40 to the second floating ball assembly 60, and the first floating ball assembly 50 can close the drain pipe 30 according to the led rainwater, so that the drain pipe 20 can drain the rainwater led into the rain and sewage well 10; the second float ball assembly 60 can close the drain pipe 20 according to the introduced sewage so that the drain pipe 30 can be discharged to the outside of the sewage introduced into the rain and sewage well 10. It should be noted that, when the rain and sewage diversion device works, rainwater and sewage flow into the rain and sewage well 10 separately.
Specifically, the first floating ball assembly 50 of the present embodiment includes a first collecting pipe 51, and a first floating ball 52 disposed in the first collecting pipe 51; the sewage inlet pipe orifice 31 of the sewage drain pipe 30 is hinged with a first valve plate 32, the first floating ball 52 is connected with the first valve plate 32 through a first connecting rope 53, the first floating ball 52 can float upwards along with the accumulation of rainwater led into the first collecting pipe 51, and the first valve plate 32 is driven to swing relative to the sewage drain pipe 30 through the first connecting rope 53 so as to block the sewage inlet pipe orifice 31 of the sewage drain pipe 30. That is, when the first float ball assembly 50 of the present embodiment works, the first float ball 52 is utilized to float the first valve plate 32 in the rainwater, and the sealing of the sewage inlet 31 on the sewage drain pipe 30 is achieved. It should be noted that, the end surface of the first valve plate 32 matched with the drain pipe 30 is an inclined surface, so that the first floating ball 51 is lifted by the buoyancy of the rainwater and can drive the first valve plate 32 to act on the sewage inlet pipe orifice 31 of the drain pipe 30, and preferably, a rubber plate may be disposed on the end surface of the first valve plate, which is close to the sewage inlet pipe orifice 31 of the drain pipe 30.
Further, the first guide cover 54 is connected to the pipe orifice of the first collecting pipe 51 in this embodiment, and the caliber of the first guide cover 54 gradually increases from the direction away from the first collecting pipe 51, so as to ensure that the rainwater guided out by the flow throwing pipe 70 can accurately enter the first collecting pipe 51.
The first bottom 511 of the first collecting pipe 51 of the embodiment is provided with a through hole (not shown), and the first connecting rope 53 penetrates through the through hole, so that the first connecting rope 53 can be connected and fixed with the first floating ball 52 and the first valve plate 32 respectively through the first collecting pipe 51; the first connecting rope 53 and the hole wall of the through hole on the first pipe bottom 511 of the first collecting pipe 51 have a gap, so that when the flow throwing pipe 70 stops throwing rainwater into the first collecting pipe 51, the rainwater placed in the first collecting pipe 51 can leak out through the gap, so that the first valve plate 31 can descend under the action of gravity after losing the tension of the first connecting rope 53, and the corresponding sewage drain pipe 30 is opened. The gap between the first connecting rope 53 and the wall of the through hole in the first bottom 511 of the first collecting pipe 51 is small enough that rainwater can accumulate in the first collecting pipe 51 when the rainwater is discharged into the first collecting pipe 51 by the rainwater pipe 70.
Similarly, the second floating ball assembly 60 of the present embodiment includes a second collecting tube 61 and a second floating ball 62 disposed in the second collecting tube 61; the water inlet pipe orifice 21 of the water outlet pipe 20 is hinged with a second valve plate 22, the second floating ball 62 is connected with the second valve plate 22 through a second connecting rope 63, and the second floating ball 62 can float upwards along with the accumulation of sewage flowing into the second collecting pipe 61, and drives the second valve plate 22 to swing relative to the water outlet pipe 20 through the second connecting rope 63 so as to block the water inlet pipe orifice 21 of the water outlet pipe 20.
Correspondingly, the second flow guide cover 64 is connected to the pipe orifice of the second collecting pipe 61 in this embodiment, and the caliber of the second flow guide cover 64 gradually increases from the direction away from the second collecting pipe 61, so that the second collecting pipe 61 is convenient for collecting sewage. And the second bottom 611 of the second collecting pipe 61 of the present embodiment is also provided with a through hole (not shown), through which the second connecting rope 63 penetrates, wherein the outer peripheral surface of the second connecting rope 63 abuts against the wall of the through hole.
In this embodiment, the flow throwing pipe 70 is obliquely installed at the tank bottom 41 of the closing tank 40, so that rainwater or sewage in the closing tank 40 is discharged from the flow throwing pipe 70 in a flow throwing manner, and rainwater and sewage with different densities can take different parabolic shapes through the flow throwing pipe 70, so that the first collecting pipe 51 of the first floating ball set price 50 can conveniently hold rainwater, and the second collecting pipe 61 of the second floating ball set price 60 can hold sewage.
Specifically, the pipe diameter of the flow throwing pipe 70 of the present embodiment is kept unchanged from the direction away from the closing-in tank 40, and then gradually decreases, so that rainwater and sewage can be thrown farther when passing through the flow throwing pipe 70, so that the first collecting pipe 51 and the second collecting pipe 61 can receive rainwater or sewage.
In addition, a return pipe 80 is connected and communicated with the tank wall 42 of the closing tank 40 in the embodiment, and the pipe orifice of the return pipe 80 is arranged towards the bottom of the rain and sewage well 10; as the necking tank 40 continues to hold rainwater or sewage, the necking tank 40 is discharged except for the holding and throwing pipe 70 as rainwater or sewage continuously enters, and then is discharged from the return pipe 80 as rainwater or sewage accumulates in the necking tank 40. The pipe diameters of the drain pipe 20 and the drain pipe 30 are larger than the pipe diameter of the return pipe 80, so that the drain pipe 20 and the drain pipe 30 can timely drain rainwater and sewage. When the rainwater is discharged into the first collecting pipe 51 through the blast pipe 70 and the sewage is discharged into the second collecting pipe 61, the first collecting pipe 51 or the second collecting pipe 61 may be filled first, then the liquid surface rises with the accumulation of the rainwater or the sewage in the necking tank 40, and then overflows to the outside through the return pipe 80.
In this embodiment, the tank opening 43 of the necking tank 40 of this embodiment is connected with the wellhead of the rain and sewage well 10 through the baffle 90, so as to guide the rainwater or sewage led in by the rain and sewage well 10 into the necking tank 40, thereby ensuring that the rainwater or sewage led in by the rain and sewage well 10 can be led into the necking tank 40.
In summary, the rain and sewage diversion device of the invention realizes the automatic closing of the drain pipe 30 and the drain pipe 20, and avoids the manual closing of the drain pipe 30 or the drain pipe 20 when entering a dangerous area by manual logging in; meanwhile, the rain and sewage diversion device is simple in structure and low in cost, and the use requirements of enterprises are further met.
