Detailed Description

In order to facilitate the understanding of the technical solutions of the present invention by those skilled in the art, the technical solutions of the present invention will now be further described with reference to the drawings attached to the specification.

As shown in fig. 1 and fig. 2, the utility model discloses technical scheme an unpowered rainwater cut-off equipment, including vatch basin 1, install mixed water inlet 3, sewage outlet 2 and rainwater export 4 on vatch basin 1. Still install the weir wall 5 that realizes sewage outlet 2 and rainwater export 4 isolation in the vatch basin 1, install the duckbilled valve 6 that the mixed water inlet of intercommunication 3 and rainwater export 4 on the weir wall 5. The position of the duck bill valve 6 is higher than that of the sewage outlet 2. The sewage outlet 2 is provided with a float valve 7.

In this technical scheme, duckbill valve is also known as the check valve, for direct purchase equipment among the prior art. The in-process of using of duckbilled valve, when pipeline internal pressure increases gradually, duckbilled valve exit can enlarge gradually and open, and the medium of pipeline will be discharged in high-speed, does not have pressure or external pressure to be greater than under the condition of internal pressure when inside, and duckbilled valve exit can present closed state, and outside medium can not be through duckbilled valve exit entering pipeline, prevents that sewage from flowing backward, so can be called the check valve.

Based on the above technical scheme, as shown in fig. 4, the unpowered rainwater cut-off device of the technical scheme has the working engineering that:

first, as shown in fig. 4 (a), in the non-rainfall or early rainfall, the amount of water entering the intercepting well is small, the buoyancy of the water is not enough to float the float 73, the sewage outlet 2 is in an open state, and sewage or rain-sewage mixed water is discharged from the sewage outlet 2.

Then, as shown in fig. 4 (b), in the middle stage of rainfall, as the amount of rainwater entering the intercepting well increases, the water level in the intercepting well gradually rises, the float 73 floats upwards by sufficient buoyancy, the valve cover 72 is driven to rotate downwards, the valve cover 72 rotates to catch the position of the sewage outlet 2, and the sewage outlet 2 is closed. According to the flotation pontoon valve theory of operation, eating sewage export 2 position in the valve gap 72 rotation, simply say that close sewage export 2, actually sewage export 2 still has certain infiltration volume this moment, can also carry out the drainage of low discharge. When the sewage outlet 2 discharges water and the water flows in rain, the water level in the intercepting well continues to rise. When the water level in the intercepting well rises to a certain height, the pressure of the water flow received by the inlet end of the duckbill valve is large enough, the duckbill valve is opened by the water flow, and rainwater in the intercepting well is discharged from the duckbill valve to the other side of the weir wall, as shown in (b) in fig. 4. Normally the duckbill valve opens automatically when the rainwater level operates the duckbill valve for 30 mm.

Then as shown in fig. 4 (c), in the middle stage of rainfall, as the amount of rainwater discharged through the duckbill valve increases, the water level reaches the position of the rainwater outlet 4, and rainwater is discharged from the rainwater outlet 4, thereby realizing flood discharge.

Finally as shown in (d) in fig. 4, in the later stage of rainfall, a large amount of rainwater is discharged by duckbill valve and rainwater outlet 4, simultaneously in the damming well weir wall towards duckbill valve outlet side, the rainwater volume increases gradually, simultaneously, 4 outside rainwater volumes of rainwater outlets increase gradually, when duckbill valve outlet water pressure is greater than duckbill valve inlet water pressure, the duckbill valve is by self-closing, the rainwater is no longer discharged from duckbill valve and rainwater outlet 4, avoid outside rainwater to flow backward to in the damming well. As shown in fig. 4 (d), a large amount of rainwater is slowly discharged from the sewage outlet 2. And finally, as the water amount in the intercepting well is gradually reduced, the buoy gradually sinks, the buoy valve is opened, and the sewage outlet 2 is opened.

In this technical scheme, the system function that the buoy valve and duckbilled valve combination system of damming can realize cutting dirty, going the flood simultaneously, does not need other auxiliary gate equipment. The structure form is simple, the installation is easy, the unpowered operation is realized, and the electric mechanical accident risk of the gate equipment is avoided. And good economic and environmental benefits are generated, such as electric charge, system software updating charge, manual maintenance charge, accident measure charge and the like.
