Multifunctional ecological water diversion device

Abstract

The invention discloses a multifunctional ecological water diversion device. The multifunctional ecological water diversion device sequentially comprises a water inlet part, a first-stage desilting part, a second-stage desilting part and a water outlet part along the water diversion direction; at least one front gate and a floating object intercepting device are arranged in the water inlet part; at least one rear gate and a filtering and adsorbing device are also arranged in the water outlet part; the first-stage desilting part comprises an annular outer shell and a flow guide ring arranged inthe outer shell; the flow guide ring is a C-shaped flow guide ring concentric with the annular outer shell; a notch of the flow guide ring is formed in the downstream face; a sand gathering pool is formed in the C-shaped flow guide ring; the second-stage desilting part comprises a desilting shell and a sand collecting pool which can be taken out through external force; the desilting shell at thejoint of the second-stage desilting part and the first-stage desilting part is a necking part; and the section shape of the sand collecting pool in the horizontal direction is consistent with that ofthe desilting shell. The device not only can effectively remove toxic and harmful substances such as large floating objects, silt and heavy metals in a channel, but also can realize multi-condition application in different water use scenes.

Description

technical field [0001] The invention belongs to the technical field of water conservancy, and relates to a channel water diversion irrigation technology, in particular to a multifunctional ecological water diversion device. Background technique [0002] Channel water diversion irrigation is to divert water from water sources to various irrigation areas and water lands for water supply and irrigation. However, most of the current water diversion channels have imperfect treatment measures for incoming water. Even if there are related treatment facilities, there are disadvantages such as single function, complex structure, and high cost. Due to economic constraints, ordinary farmers and fishers have to reduce their water requirements. They seldom install existing filtering devices in the market. They often only set up a simple block, or rely on treatment facilities such as grit chambers and filters, but the project cost is still high. High, and the efficiency of sand removal a...
