Water lift irrigated project, specifically a kind of side gulf structure for reducing river and irrigating by lifting water to a higher level with a water pump, etc. water silt content.
Background technology
Pumping irrigation station on China only the Yellow River just has more than 10, year the billions of sides of water lift amount, yellow irrigated area area reaches tens million of mus,
The only high lift lift irrigated project year water lift amount 400,000,000 of scape electricity is multi-party, and irrigated area just reaches mus up to a million.Since sand content in river water is high,
If the Yellow River is 5.09kg in every cubic metre of the average sediment charge of Jingtai section.River load content is high, is on the one hand set to irrigating by lifting water to a higher level with a water pump, etc.
It is standby, especially to the serious wear of pump；On the other hand, it significantly increases and irrigates by lifting water to a higher level with a water pump, etc. cost, while lower reservoir, farmland also being given to convey
A large amount of silts.However, up to the present, the silt filtering technique and device that home and abroad is still irrigated by lifting water to a higher level with a water pump, etc. without being used for river, and only
It is that part stops the larger rubbish of livestock, faggot and other volumes for being flooded using fence.
Invention content
The purpose of the present invention is to provide a kind of reduction rivers simple in structure, implementing to be easy, implementation result is good to irrigate by lifting water to a higher level with a water pump, etc. water
The side gulf structure of silt content.
To achieve the goals above.The present invention adopts the following technical scheme that：A kind of side reduced river and irrigate by lifting water to a higher level with a water pump, etc. water silt content
Gulf structure, including irrigate by lifting water to a higher level with a water pump, etc. pump pond；It is characterized in that：It is provided in the side on riverbank and irrigates by lifting water to a higher level with a water pump, etc. side gulf, irrigated by lifting water to a higher level with a water pump, etc. side gulf and enclosed equipped with side gulf
Wall irrigates by lifting water to a higher level with a water pump, etc. one side that side gulf river flows through and is equipped with side gulf Wan Kou be connected to river, irrigates by lifting water to a higher level with a water pump, etc. to pump pond and be placed in and irrigate by lifting water to a higher level with a water pump, etc. in the gulf of side, side gulf
Direction is equipped with the gulf mouthful wall docked with side gulf enclosure wall in the flow in gulf mouthful.
The other end of gulf mouthful wall extends to river side, and shape forms an angle between the section of gulf mouthful；That is gulf mouthful wall is whole
Body is skimmed to outside river direction, and angle is constituted with gulf mouthful section.It irrigates by lifting water to a higher level with a water pump, etc. pump pond and is located at the position farthest from side gulf gulf mouthful；Side gulf bottom
Equipped with to the inclined slope surface in river direction.
The present invention provides the setting of side gulf and irrigates by lifting water to a higher level with a water pump, etc. side on riverbank, and side gulf three side sealing closes, and river flows through one side and is open, and in side
Gulf mouthful wall is built in side in the flow in gulf gulf mouthful, pumps the farthest distance Wan Kou in the side gulf of pond setting.Its simple in structure, implementation
It is easy.When river water edge flows through side gulf gulf mouthful, direction can be changed, from the side inflow sides Wan Wankou gulf.Into irrigate by lifting water to a higher level with a water pump, etc. the water in side gulf because
Change flow direction and obviously slow down, a large amount of silts can sink to side gulf bottom because of gravity after deceleration.Since side gulf bottom is equipped with to river
The inclined slope surface in direction is flowed, the silt for sinking to side gulf bottom can be taken out of to the water of exteenal reflux.Due to irrigating by lifting water to a higher level with a water pump, etc. pump pond in side gulf
Most the inside, the i.e. highest point in side gulf ramped bottom surface, thus the sediment charge in pump pond is irrigated by lifting water to a higher level with a water pump, etc. with respect to the sediment charge in river water
It can greatly reduce.
And then the abrasion for irrigating by lifting water to a higher level with a water pump, etc. equipment, especially water pump is alleviated, it reduces to lower reservoir, farmland sediment.Side gulf
The distance in the gulf ponds Kou Zhibeng is longer, and side gulf area is bigger, then buffers that leeway is bigger, that is, the water flow velocity in approaching side gulf is slower, sinks
Forming sediment, the time is also longer, and the effect that cement sand is irrigated by lifting water to a higher level with a water pump, etc. in reduction is more notable.
It is that gulf mouthful wall extends outwardly that the other end of gulf mouthful wall extends to river side, is conducive to increase on the outside of the wall of gulf mouthful
River flow velocity helps to increase the effluent angle for entering and irrigating by lifting water to a higher level with a water pump, etc. side gulf water.
It is equal into the water for irrigating by lifting water to a higher level with a water pump, etc. side gulf and irrigates by lifting water to a higher level with a water pump, etc. pump pond and irrigate by lifting water to a higher level with a water pump, etc. water.Thus, flow velocity and the side gulf of side gulf gulf saliva
Gulf mouthful basal area size is in inverse ratio, that is, side gulf gulf mouthful basal area is bigger, then at side gulf gulf mouthful the flow velocity of water with regard to smaller；And because of object
The gravity of body is in inverse ratio with movement velocity, thus water velocity is slower, is more conducive to sediment settlement, thus the silt in approaching side gulf
Amount is fewer.In consideration of it, the width in side gulf gulf mouthful should be suitably wider.
The flow velocity being far smaller than due to the water velocity in the gulf of side in river.It is in the principle of inverse ratio according to flow velocity and pressure,
It draws water in the gulf of side when irrigating by lifting water to a higher level with a water pump, etc., it is the diving depth to draw water in river that the diving depth of pump, which is smaller than directly, can also be effectively reduced
Silt.
