The specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model is further described.
As shown in Figure 1, finned efficient swash plate removes sand, and water fetching device is separated by intake chamber 2, silt and 8 three parts in certainly clear chamber 5 and water-supplying chamber are formed.Intake chamber 2 is positioned at water fetching device foremost, and its front portion is provided with pyramid type protecgulum 1.Described silt separates and is positioned in the middle of the water fetching device from clear chamber 5, water-supplying chamber 8 be connected silt separate with from the rear end of clear chamber 5, header 7 ends pick out outlet pipe 9.
Referring to Fig. 2, silt separate with the first half from clear chamber 5 be silt separation chamber 6, the latter half connects from the husky bucket 10 of the clear row sand tube 11 that runs in from the husky bucket of clear row 10 bottoms.Along the water (flow) direction branch lateral flow inclined plate 12 that is symmetrically arranged, lateral flow inclined plate 12 distance between plates between any two on each limit is from being L in the silt separation chamber 6 of the first half
18 ~ 10cm is preferably 9cm, and lateral flow inclined plate 12 is 45 ° ~ 70 ° with the angle of horizontal plane, preferably adopts 60 °, and is equipped with on lateral flow inclined plate 12 and all vertical fin 13 in water (flow) direction and swash plate plane, and the distance between the fin is L in twos
24 ~ 7cm, its middle distance is preferably 6cm, and the position of swash plate axis of symmetry is provided with sediment settlement gallery 14, makes silt be settled down to the husky bucket of row by gallery.
Silt separates and the latter half from clear chamber 5 is from clear husky bucket 10 and the row's sand tube 11 arranged, and the semicircle watertight shutter 15 of backwater flow path direction has been installed in the husky bucket 10 of wherein clear certainly row, arranges and is provided with the oblique watertight shutter 16 of interlaced arrangement down in the sand tube 11.
Also be provided with water conservancy diversion district 3 in silt separation and front end from clear chamber 5, front end in water conservancy diversion district 3 is equipped with deflector 4, deflector 4 be one on its plate face the intensive rectangle orifice plate that is drilled with many circular ports equably, three limits in the limit, the left and right sides of deflector 4 and top are separated with the locular wall of certainly clear chamber 5 with silt and are connected, for separating with silt with locular wall from clear chamber 5, the bottom of arranging husky deflector 4 leaves certain distance, the husky passage of the row of formation.
Be provided with the header 7 that the surface is drilled with intensive inlet opening in the water-supplying chamber 8, the water in the water-supplying chamber 8 is collected the back by header 7 and is flowed in the outlet pipe 9.
The mode of occupation of this water fetching device:
Above-mentioned water fetching device is installed and fixed on the basis, riverbed, the parallel installation in water fetching device axle center with water (flow) direction, wherein circular cone cover 1 is over against flow direction, and the water fetching device top is not had by water logging fully, the husky space greater than the row of 1m is left in the below, and broad water stream channel is left in both sides.
During water intaking; when containing the river process water fetching device of floating things such as weeds; because the surface is that the hydraulics of the corrugated intake chamber of semicircle 2 is good; the extension that can reduce floating things such as weeds effectively is stifled; so the former water that only contains silt 18 enters intake chamber 2 from the inlet opening; current slowly flow at intake chamber 2; the oarse-grained grains of sand can be deposited on the base plate of intake chamber 2 in very fast effect owing to gravity in the water; discharge intake chamber 2 by the husky dual-purpose hole 19 of water inlet row again, can prevent effectively that so the precipitated silt that gets off in inlet opening on the intake chamber base plate from stopping up.
And then current are by the deflector 4 in the water conservancy diversion district 3, deflector 4 is regulated flow-shape all even stable by evenly intensive circular inlet opening, its surface, the current of even velocity of flow enter in the silt separation chamber 6 then, silt separation chamber 6 is made up of with being equipped with on swash plate with all vertical fin 13 symmetric arrangement in water (flow) direction and swash plate plane lateral flow inclined plate 12, the fin swash plate is to utilize gravity, fluid resistance and inertia force carry out Dynamic Separation to the grains of sand, surface loading is very low, therefore can be grains of sand precipitation separation slowly downhill race to lateral flow inclined plate 12 and on swash plate from former water that particle diameter is very little in the former water, and the position of swash plate axis of symmetry is provided with sediment settlement gallery 14, so the grains of sand under the downhill race can be pooled in the husky bucket 10 of clear row by sediment settlement gallery 14, until discharging by row's sand tube 11.At the clear certainly water of arranging sand bucket 10 and arranging in the sand tube 11 is relative static, and it is the same in the effect of the watertight shutter 16 that in the semicircle watertight shutter 15 that is provided with in the husky bucket 10 of clear row, row's sand tube 11, is provided with the effect of flap valve, sand can be gone out can not be advanced, because husky proportion is greater than water, so sand can continuously be discharged, thereby reach the purpose of efficiently removing sand.
The removed former water of most of grains of sand continues to flow forward, enters water-supplying chamber 8 through deflector, and what enter outlet pipe 9 by header 7 at last is only to contain the extremely former water of safety of the tiny grains of sand.
The utility model profile is a rectangle, and exterior material can adopt ordinary carbon steel or corrosion resistant plate, and the inner tab swash plate can adopt plastic plate.The utility model is reasonable in design, and compact conformation is easy to manufacture.Can be widely used in the rivers that floating thing is more, the higher particularly fine sand of sediment charge content is higher such as weeds, not only can prevent the obstruction of floating thing such as weeds in the sealing effectively, can also remove the silt in the water efficiently, can save and build special sand trap (preliminary sedimentation tank), thereby can simplify follow-up water treatment technology, reach the wearing and tearing that alleviate water pump vane and follow-up water treatment building, save capital investment, save and take up an area of, reduce the purpose of water intaking cost.
