Rainwater after eaves gutter 3 compiles, the roof drain 4 of the end lower position through being installed on eaves gutter 3, the room of flowing through then is installed on the rain leader downspout 5 of room exterior wall, the dmp filter device 6 of flowing through again after filtering, gets into rainwater storage tanks 8 through rainwater collecting pipe 7 and stores for future use.
This technical scheme is simple in structure, it is convenient to implement, and collected rain water on roof is stored in water tank through filtration, general service such as can be used for irrigating, afforest, flush the toilet then, thereby practiced thrift water quality tap water preferably.
As a kind of preferred version, be provided with screen pack in the strainer 6, be provided with filtration beds below the screen pack.Filtration beds in the strainer 6 comprises sand filter blanket, and the material of sand filter blanket is a kind of in medium sand, fine sand, the quartz sand; Filtration beds also comprises activated carbon layer, activated carbon layer be positioned at sand filter blanket below.For example sand filter blanket can be selected quartz sand, can effectively remove the suspension in the rainwater, if further add activated carbon layer, can remove part microorganism, stink, colourity, heavy metal, colloid and some other organic pollutions in the rainwater.Wherein, can select one deck or two-layer according to demand for filtration beds.
In addition, dmp filter device 6 preferably is installed in rain leader downspout 5 apart from one meter high position, ground.Strainer 6 can link together with removably and rain leader downspout 5, rainwater collecting pipe 7, can remove foreign material at any time like this, upgrades filtration beds.
As another kind of preferred version, rainwater storage tank 8 is buried, can practice thrift land space like this, so the less architecture ensemble in suitable space is by land arranged this system.
As another preferred version, roof drain 4 is hydrocone types, can accelerate the discharge of eaves gutter 3 ponding like this.
As a kind of preferred version also, rain water on roof utilizes system to comprise power supply control cabinet 89; Water pump 9 is full-automatic self-priming water pump, and it sets up pressure switch (not illustrating in the accompanying drawing), and water pump 9 links to each other with power supply control cabinet 89 through cable; Rainwater storage tank 8 is buried; The tank skin of buried rainwater storage tank 8 and tank deck are self to be bent to form many reinforcing rings and reinforcing rib; The tank body bottom is provided with bearing, and port lid is arranged at top, and tank body is provided with water inlet pipe 81, overflow pipe 83, water pump suction pipe 85, filling pipe 82; Be provided with the unsteady suction head 86 of two unsteady liquid-level switch 10-1 and 10-2 and water pump in jar, and guiding standpipe 84; The unsteady suction head 86 of water pump is sleeved on the guiding standpipe 84; The water pump suction pipe upper end links to each other with the water inlet of water pump 9, and the lower end links to each other with the unsteady suction head 86 of water pump; Liquid-level switch 10-1 is connected with electric control box 89 through cable respectively with 10-2.
Rainwater gets into through rainwater collecting pipe 7 and buries ground rainwater storage tank 8.During full water, unnecessary rainwater enters sewer through overflow pipe 83 in jar.Water pump 9 is full-automatic self-priming water pump.The unsteady suction head 86 of water pump can fluctuate along guiding standpipe 84, to guarantee to draw the upper strata high-quality water of next depthkeeping degree of liquid level.During user's water, the pressure switch that full-automatic self-priming water pump is set up perceives pressure decline in the water pipe, starts water pump 9 and supplies water; The user stops water, and pressure raises in the water pipe, and pressure switch control of pump 9 is out of service.During lack of water, can artificial open the manually-operated gate 5-2 moisturizing on the filling pipe in the storage tank, or automatic water supplement.The automatic water supplement mode is provided with electromagnetic valve 90 on filling pipe 82, electromagnetic valve 90 is formed the series-fed circuit with unsteady liquid-level switch.During low water stage, the liquid-level switch that floats is closed, and electromagnetic valve 90 is connected, and carries out moisturizing; During moisturizing to designated water level, the liquid-level switch that floats breaks off, and electromagnetic valve 90 is broken into and opens circuit, and moisturizing stops.Liquid level change in the basin is shown on the panel of power supply control cabinet 89 by indicator lamp.Indicator lamp and unsteady liquid-level switch are concatenated into power supply circuits, and through the switching of unsteady liquid-level switch with water level, the light on and off of control indicator lamp shows water level.The unsteady suction head of water pump is sleeved on the 86 guiding standpipes 84, can fluctuate along guide pipe 84.The tank body of buried rainwater storage tank 8 is made with polythene material, and is easy to process, and cost is lower.
The parallelly connected valve group of manually-operated gate 5-2 and electromagnetic valve 90 is housed on the filling pipe 82, can selects craft or automatic water supplement mode like this.
Rain water on roof utilizes system to comprise a plurality of buried rainwater storage tanks, links to each other through pipeline or pump installation each other, can determine the reserves of rainwater like this according to demand.
Rain water on roof utilizes system to comprise solar panel, and solar panel is that water pump 9 provides working power, and through utilizing solar energy, this rain water on roof utilizes system to realize zero charcoal discharging, is the system of a full green.
In a word; Rain water on roof of the present invention utilize system architecture simple, implement convenient; Except filtering leaf in the rainwater, branch etc., also can remove the suspension in the water effectively, and the organic matter in the water, colloid, iron, manganese etc. are also had tangible removal effect than bigger material; Through general services such as the water that filters can be used for irrigating, afforest, flush the toilet, practiced thrift high-quality tap water; In addition, the buried rainwater storage tank that is adopted has been practiced thrift land space, is particularly suitable for the urban area narrow and small in the space and arranges.
Though the present invention discloses as above with preferred embodiment; Right its is not in order to limit the present invention; Any person of ordinary skill in the field; In spirit that does not break away from the present invention and scope, when can doing a little change and improvement, so the present invention's protection domain is as the criterion when looking the claim person of defining.
