Embodiment
In order to make the purpose of this utility model, technical scheme and advantage clearer,, the utility model is further elaborated below in conjunction with drawings and Examples.Should be appreciated that specific embodiment described herein only is used to explain the utility model, and be not used in qualification the utility model.
As shown in Figure 1, in this embodiment, rainwater catchment system of the present utility model system, comprise the base circumference that is arranged on greenhouse 1 collecting ditch 2, be arranged on filter course 5 and flexible porous tube 4 in the collecting ditch 2, and rainwater storage tank 6, wherein,
Collecting ditch 2 is arranged on the ceiling in greenhouse 1 than downside, and flexible porous tube 4 is provided with near the bottom of collecting ditch 2, and filter course 5 is arranged on the outside of flexible porous tube 4, and the delivery port of flexible porous tube 4 is connected to rainwater storage tank 6.
The rainwater that the utility model will drop on the greenhouse 1 is collected the collecting ditch 2 that its ceiling is provided with than the downside base portion, and in collecting ditch 2, be provided with filter course 5, rainwater is filtered for the first time, filter out the bigger impurity fragment of volume etc., rainwater filters once more by flexible porous tube 4 then, flexible porous tube 4 can filter out the impurity such as dregs in the rainwater, can guarantee the water quality behind the dmp filter, and rainwater flows into rainwater storage tanks 6 by flexible porous tube 4.Thereby the utility model can utilize the greenhouse to collect and utilize rainwater, and collects water quality rainwater preferably.
In order to prevent that rain penetration that collecting ditch 2 collects in soil, can be equipped with impervious barrier 3 at collecting ditch 2.Then flexible porous tube 4 is laid on above the impervious barrier 3, the rainwater of collecting in the collecting ditch 2 can all enter flexible porous tube 4 after filtration like this.Further, impervious barrier 3 is preferably the antiseepage composite geo-membrane.
In order to reduce cost, filter course 4 of the present utility model can adopt metalling simultaneously, and it is drawn materials conveniently, and the granular debris of filtering larger volume is respond well.
When collecting rainwater, rainwater flows in the rainwater storage tank 6 smoothly in the flexible porous tube 4 in order to make, and collecting ditch 2 can be provided with the gradient, and the delivery port of flexible porous tube 4 is positioned at the gradient least significant end of collecting ditch 2.Further, collecting ditch 2 position therebetween forms gradient least significant end, i.e. the end, slope, and the delivery port of flexible porous tube 4 is connected to the rainwater storage tank in the centre position of collecting ditch 2.
As can be seen, rainwater storage tank 6 is provided with near collecting ditch 2 from attached Fig. 1 and 2, and according to different needs, rainwater storage tank 6 can be arranged on the position of any appropriate.In addition, greenhouse described in the utility model can be but be not limited to agricultural facility buildings such as greenhouse by solar heat, plastic tunnel, it can also be equal to replace with such as between outdoor equipment, non-agricultural facility building such as room, warehouse.
The utility model also provides a kind of rainwater catchment system method, and the method comprising the steps of:
S10: rainwater is collected in the collecting ditch of the base circumference that is arranged on the greenhouse;
S20: the rainwater that utilizes filter course tentatively to be collected in the collecting ditch filters for the first time;
S30: utilize the rainwater after flexible porous tube will filter for the first time to carry out the filtration second time, and the rainwater after will filtering for the second time is collected in the rainwater storage tank.
The rainwater catchment system method that the utility model provides, at first rainwater is tentatively collected in the collecting ditch of the base circumference that is arranged on the greenhouse, flow in the rainwater storage tank by the flexible porous tube delivery port at last by filter course in the collecting ditch and flexible porous tube then, collect.Thereby the utility model can utilize the greenhouse to collect rainwater, and collects water quality rainwater preferably.
For rainwater unlikely infiltration in collecting ditch is flowed away, described collecting ditch has the antiseepage effect.The rainwater of collecting in the collecting ditch can all enter flexible porous tube after filtration like this.
In order to reduce cost, described filter course is a metalling simultaneously, and it is drawn materials conveniently, and the granular debris of filtering larger volume is respond well.
When collecting rainwater, flow into smoothly in the rainwater storage tank in order to make the rainwater in the flexible porous tube, described collecting ditch has the gradient, and the delivery port of flexible porous tube is connected to the rainwater storage tank in the least significant end of the gradient.Further, collecting ditch forms gradient low side in its vertical centre position, and the delivery port of flexible porous tube is connected to the rainwater storage tank in this centre position.
The utility model can be collected in rainwater in the rainwater storage tank, and the rainwater of collection is through twice filtration, and water quality is better, and be collected in rainwater in the rainwater storage tank can be at any time by water pump or manually take.The utility model can also alleviate surface gathered water and muddy situation about can't bear behind the rain when saving utilizes water resource.
Above-mentioned only is preferred embodiment of the present utility model, certainly, with further exploration other embodiments can also be arranged according to actual needs.But, should be clear and definite be that the conversion based on similar embodiment with same idea above-mentioned or that other are not explained out all should be encompassed among the protection domain of the utility model claim.
