Problems solved by technology

This kind of method can play a better role, but when a flood occurs, it is often accompanied by a large amount of silt or other debris, so it will block the combing channel, thereby reducing the effect
Moreover, when the water flow is large, the dam will have limited drainage and there will be no time for drainage, which will put pressure on the dam.

Embodiment Construction

[0009] Combine below figure 1 Specific description embodiment:

[0010] Such as figure 1 As shown, a river flood control mechanism includes a dam 1, a side of the dam 1 is provided with a plurality of gates 2, and the side of the dam 1 provided with the gates 2 is connected with a diversion device 3, so The above-mentioned diversion device 3 includes several water flow channels 4, the water flow channels 4 are parallel to each other, and an inclined channel 5 is opened between the above-mentioned several water flow channels 4, and the described inclined channel 5 is sequentially divided from the water inlet end to the water outlet end. There are several groups, and the inclined channels in each group are distributed in steps. The dam 1 is provided with a pumping station 6 , and the water outlet of the pumping station 6 communicates with the water flow channel 4 of the distribution device 3 .

[0011] When in use, the water flows out from the gate of the dam and enters the d...

Abstract

The invention belongs to the technical field of tools for flood fighting and treating of rivers, and particularly relates to a river flood fighting and treating mechanism. The river flood fighting and treating mechanism comprises a dam, and is characterized in that a plurality of gates are formed in one side of the dam, a flow dividing device is connected to the side, with the gates, of the dam, the flow dividing device comprises a plurality of water flow channels which are parallel to one another, inclined channels are formed among the water flow channels, the inclined channels are sequentially divided into multiple sets from water inlet ends to water outlet ends, and all the inclined channels in each set are distributed in a ladder shape. The river flood fighting and treating mechanism is capable of well removing sludge and sundries, and not prone to blocking.

Description

technical field [0001] The invention belongs to the technical field of river flood control appliances, in particular to a river flood control mechanism. Background technique [0002] At present, during the rainy season in China, there will be floods in the Yangtze River Basin, Heilongjiang River and Songhua River Basin due to more rain. At present, the main means of controlling flood disasters are: 1. Relying on blocking, using mud and rocks and other blockages to block the flood mouth of the dam, thus playing a certain role, but this type of method often has little effect, and sometimes leads to greater damage. The problem. The second is to divert the dams in the areas where floods occurred by combing and diverting, thereby reducing the water flow and achieving the goal. This type of method can play a good role, but when a flood occurs, it is often accompanied by a large amount of silt or other debris, so the channel for combing will be blocked, thereby reducing the effec...
