Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of reservoir drawdown band of the utility model water resource Collection utilization system.
In accompanying drawing, the list of parts representated by each label is as follows:
1, high-level reservoir, 2, diversion ditch, the 3, first screen pack, the 4, second screen pack, 5, diversion mechanism, 6, block hydrosphere, 7, low level reservoir.
Detailed description of the invention
Be described principle of the present utility model and feature below in conjunction with accompanying drawing, example, only for explaining the utility model, is not intended to limit scope of the present utility model.
As shown in Figure 1, the utility model comprises high-level reservoir 1, low level reservoir 7, diversion mechanism 5, and described diversion mechanism 5 tilt distribution is on described falling zone, and the two ends of described diversion mechanism 5 lay respectively at highest point and the lowest part of described falling zone.Described high-level reservoir 1 is arranged on the highest point of described falling zone, and is connected with the top of described diversion mechanism 5, high-level reservoir 1 uncovered, and convenient chemical fertilizer of dusting crops with an insecticide in high-level reservoir 1, improves crop yield.Described low level reservoir 7 is arranged on the lowest part of described falling zone, and is connected with the bottom of described diversion mechanism 5.Difference in height between described high-level reservoir 1 and described low level reservoir 7 is between 20 ~ 25m, utilizes difference in height to realize automatic streamline.The shape of described high-level reservoir 1, described low level reservoir 7 is cuboid or cylindrical, and the shape of high-level reservoir 1 and low level reservoir 7 can set according to irrigated area and actual needs.If the water capacity of high-level reservoir 1 100 tonnes, irrigated area should more than 0.5 hectare; If water capacity is 200 tonnes, irrigated area more than 1 hectare, should carry out according to the size of irrigated area the size arranging high-level reservoir 1, and the water capacity of low level reservoir 7 is less than the water capacity of high-level reservoir 1.The top of described low level reservoir 7 be installed with its mating shapes block hydrosphere 6, block the water capacity of hydrosphere 6 for increasing low level reservoir 7, described in block hydrosphere 6 and be made up of stainless steel or duroplasts.
As shown in Figure 1, the both sides of described diversion mechanism 5 are evenly provided with many diversion ditches 2, many described diversion ditch 2 is staggered uniformly relative to diversion mechanism 5, adopt even staggered pattern, increase water velocity, increase irrigated area, can increase irrigation efficiency, the quantity of diversion ditch 2 can irrigated area set as required, and diversion ditch 2 can directly be dug out on falling zone also can adopt plastic flexible pipe.The side of described high-level reservoir 1 is provided with delivery port, and described delivery port is communicated with the top of described diversion mechanism 5, and described water outlet is provided with the first screen pack 3.The side of described low level reservoir 7 is provided with water inlet, and described water inlet is communicated with the bottom of described diversion mechanism 5, and described water inlet is provided with the second screen pack 4.Described water inlet and described water outlet are equipped with U-shaped draw-in groove, and shape and the described U-shaped draw-in groove of described first screen pack 3, described second screen pack 4 match, and described first screen pack 3, described second screen pack 4 are installed in described U-shaped draw-in groove.Arranging U-shaped draw-in groove can make the first screen pack 3 and the second screen pack 4 to clamp, and avoids departing from because of water impact.The mesh of described second screen pack 4 is less than the mesh of described first screen pack 3, and described first screen pack 3, described second screen pack 4 are made up of filter cloth or stainless steel wire.When needs are irrigated, the second screen pack 4 is installed in water inlet, has certain inhibition to current, realize the object of damming, make current flow to diversion ditch 2 more fully, filter silt simultaneously; After irrigation completes, the second screen pack 4 is taken off, water source unnecessary in high-level reservoir 1 is flow in low level reservoir 7.Described diversion mechanism 5, described delivery port, described water inlet are all located along the same line with the bevel on the earth's surface of described falling zone.In use, diversion mechanism 5 can be drainage trough or primer pump, when the water of high-level reservoir 1 can flow automatically, adopts drainage trough, and drainage trough adopts concrete now to build; When the water of high-level reservoir 1 can not flow automatically, primer pump is adopted to provide power for water source.
Its course of work is: carry out retaining in the season that rainfall is plentiful by high-level reservoir 1 and low level reservoir 7, when by the time needing to irrigate, install the second screen pack 4, the water yield in high-level reservoir 1 is sufficient, pass through difference in height, and under Action of Gravity Field, water source flows out from delivery port and carries out soil irrigation, if carry out water source conveying by primer pump time water source can not directly flow through diversion mechanism 5 to the inflow of each diversion ditch 2.When irrigation completes, unload the second screen pack 4, unnecessary water source is flow into and is provided with storage in the low level reservoir 7 blocking hydrosphere 6.
Kind ground usable floor area according to falling zone can be circularly set this water resource Collection utilization system, be circularly set in the starting point of the lower low level reservoir of physical features as this water resource Collection utilization system, body fully improves the Collection utilization of water resource, alleviate falling zone water shortage problem, the area that this water resource Collection utilization system also can be used for rainfall few is promoted.
The foregoing is only preferred embodiment of the present utility model, not in order to limit the utility model, all within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
