By using above-mentioned technical proposal, by hoist engine emergency gate is controlled to lift, can quickly control emergency brake
The keying of door.
The utility model is further arranged to：Vertical shaft venthole is provided at the pump outlet.
By using above-mentioned technical proposal, since water hammer pressure is larger at pump outlet, during water drainage, the gas that is generated between Shun
It presses larger, by the vertical shaft venthole of setting, air pressure is exported, reduce the influence to flood control flap valve and emergency gate.
The utility model is further arranged to：The pipelined channel bottom and water outlet box culvert bottom are provided with reinforcing layer,
The reinforcing layer includes reinforced concrete backplane level, concrete bed course and cement stone dust bed course successively.
By using above-mentioned technical proposal, in the reinforced concrete bottom plate that pipelined channel and water outlet box culvert bottom are set gradually
Layer, concrete bed course and cement stone dust bed course improve the fastness of bottom, reduce the percussion of flood.
The utility model is further arranged to：The water inlet of the water inlet flow channel sets bulkhead gate.
By using above-mentioned technical proposal, in the bulkhead gate that the water inlet of water inlet flow channel is set, facilitate water inlet flow channel
And the maintenance of water pump.
The utility model is further arranged to：The bulkhead gate front end sets trash rack.
By using above-mentioned technical proposal, the trash rack of setting reduces rubbish and enters in water inlet flow channel, rubbish is avoided to damage
Bad water pump.
The utility model is further arranged to：The water outlet box culvert outlet is connected with rivers, and the water outlet box culvert surrounding is equal
It is vertically arranged with water stop.
By using above-mentioned technical proposal, water outlet box culvert upper and lower surface is vertically arranged water stop, prevent fluviatic water from
It is flowed into the soil body in the soil body of water outlet box culvert upper and lower surface, improves the stability of water outlet box culvert.
In conclusion the utility model has the advantages that：
First, when the water level on water inlet flow channel is higher than river level, the water in water inlet flow channel is evacuated to water tank by water pump
Contain, be then discharged at rivers and discharge, prevent urban waterlogging, during water pump operation, water impact flood control flap valve causes flap valve of controlling flood
On fixed screw come off, and then when so that the flood control flap valve is come off, close the emergency gate of flood control flap valve front end, prevent flood from falling
It fills, while also is used as bulkhead gate when flood control flap valve overhauls；
Second, since water hammer pressure is larger at pump outlet, during water drainage, the air pressure generated between Shun is larger, passes through setting
Vertical shaft venthole, air pressure is exported, reduce to flood control flap valve and emergency gate influence.
