The device not only can adopt the energy of the mobile water stream to separate the water from the sand, and has good separation effect, but also spends less time to discharge the sand, and consumes less water, and can realize the continuous water supply, and is convenient for the engineering management.
Description
Technical field
The utility model relates to the water and sand separating device of hydraulic engineering, belong to utilize dynamic current self energy with water and sand separating device, particularly compound desilting canal.
Background technology
The river, Xinjiang belongs to flashy stream more, and sand content is big and thickness is inhomogeneous, and the sediment concentration in the river reaches tens of even hundreds of kilograms per cubic meter, and this brings very big harm and inconvenience to industrial water use and people's lives water.Aspect agricultural water, silt deposits in the channel of being everlasting and has a strong impact on the channel discharge capacity, has seriously restricted advanced technologies such as spray, drip irrigation applying that I distinguish.
In order to solve silt alluvial problem in the channel, adopted the sand trap of various ways, can be divided into linear sand trap, shaped form sand trap, desilting bar canal shape sand trap etc. by its form.
The sand trap that the linear sand trap can be divided into single chamber, two chamber, multicell and have the side canal.
The shaped form sand trap is to utilize the bend circulation theory that water sand is separated, because the flow rate of water flow in the bend is compared with other type sand trap, its numerical value is bigger, thereby is applicable to mountain area or location, river valley.But the alluvial situation of the domestic shaped form sand trap of building in Xinjiang all compares seriously at present.
Desilting bar canal generally is applied to middle and lower reaches area, the Yellow River, and this sand trap is to utilize natural depression desilting, can improve the soil, and enlarge and plough, but it is not suitable for Xinjiang region.
Summary of the invention
The purpose of this utility model is to provide a kind of compound desilting canal, not only can utilize the energy of dynamic current self that water sand is separated, the husky good separating effect of water, and the husky used time ratio of row is less, it is few to arrange husky water supply volume, and can realize continuous water supply, is convenient to engineering management.
The utility model is achieved in that a kind of compound desilting canal, be included in the overflow weir and the scour gallery that are provided with on the channel, desilting gallery with longitudinal grade is being set in the bottom of top channel, the uniform aperture that communicates with the desilting gallery that is being provided with on the base plate of top channel, on the aperture, the waterpower automatic panel-turnover is installed by the rotating shaft cooperation, the axial location of rotating shaft is at the eccentric position of waterpower automatic panel-turnover face, make the turnover panel area that is positioned at axis one side greater than the turnover panel area that is positioned at the axis opposite side, and the gravitational moment that is positioned at axis both sides turnover panel equates, on the channel base plate of the top of desilting gallery head, the water inlet that communicates with the desilting gallery is being set, is connecting the scour gallery that is provided with scouring sluice at the afterbody of desilting gallery.
Because the utility model is being provided with the desilting gallery with longitudinal grade in the bottom of top channel, constitute a water stream channel, sediment laden flow enters the desilting gallery by the water inlet of top channel.At first flow in the bottom surface of desilting gallery, along with water level raises, the water level of rising produces water pressure to the waterpower turnover panel of level then, and the water pressure that both sides produce equates, make the waterpower automatic panel-turnover still remain static, be increased to the top channel with water level, current are subjected to the effect of overflow weir, and the water level in the channel of top rises, the cross-section of river increases, flow velocity reduces, and the silt in the water sinks in the desilting gallery, and the top current overflow clear water from the overflow weir at channel rear portion, top.Scouring sluice in opening scour gallery, the silt of alluvial in the desilting gallery is washed away, this moment, upright waterpower automatic panel-turnover was under flowing pressure and action of gravity along with the decline of water level, produce turning torque, force the waterpower automatic panel-turnover to rotate, overlap with channel bottom surface, top for 90 ° to its upset, a current part is passed through from the top channel at this moment, a part is passed through from the desilting gallery, is used for sand surfing.The energy that the utility model not only can utilize dynamic current self separates water is husky, the husky good separating effect of water, and the husky used time ratio of row is less, and it is few to arrange husky water supply volume, is convenient to engineering management.
