The rainwater collecting and utilizing system has the advantages of simple structure, low cost and convenience in use.
Description
Technical field
The utility model is an a kind of rainwater catchment system system, belongs to the renovation technique of rainwater catchment system system.
Background technology
Rainwater utilization is a new system engineering in the water resources comprehensive utilization, has good water saving usefulness and environmental ecological benefit.China's urban water shortage problem is serious day by day at present, meanwhile, healthy residence, ecodistrict, the positive fast development of Green Public Building, building rainwater utilization system has adapted to the present situation and the demand in city with its good water-saving benefit and environmental ecological benefit, has broad application prospects.But existing building all is not provided with the rainwater catchment system system.
The utility model content
The purpose of this utility model is to consider the problems referred to above and provides a kind of simple in structure that cost is low, rainwater catchment system system easy to use.
The technical solution of the utility model is: rainwater catchment system of the present utility model system, include rainwater collecting pit, automatic rinse water strainer, clear water reserviors, rainwater flow-discarding device, the rainwater flow-discarding device that wherein is used to collect rain water on roof is located at the annex roofing, the delivery port of rainwater flow-discarding device communicates with the water inlet of rainwater collecting pit, the delivery port of rainwater collecting pit communicates with the water inlet of automatic rinse water strainer, and the delivery port of rinse water strainer communicates with the water inlet of clear water reserviors automatically.
The utility model is because employing includes the rainwater collecting pit, automatic rinse water strainer, clear water reserviors, rainwater flow-discarding device, the rainwater flow-discarding device that wherein is used to collect rain water on roof is located at the annex roofing, the delivery port of rainwater flow-discarding device communicates with the water inlet of rainwater collecting pit, the delivery port of rainwater collecting pit communicates with the water inlet of automatic rinse water strainer, the structure that the delivery port of automatic rinse water strainer communicates with the water inlet of clear water reserviors, therefore, the utility model is simple in structure, cost is low, easy to use, be that a kind of design is ingenious, function admirable, convenient and practical rainwater catchment system system.
Description of drawings
Fig. 1 is a schematic diagram of the present utility model.
The specific embodiment
Embodiment:
Schematic diagram of the present utility model as shown in Figure 1, rainwater catchment system of the present utility model system, include rainwater collecting pit 1, automatic rinse water strainer 2, clear water reserviors 3, rainwater flow-discarding device 4, the rainwater flow-discarding device 4 that wherein is used to collect rain water on roof is located at the annex roofing, the delivery port of rainwater flow-discarding device 4 communicates with the water inlet of rainwater collecting pit 1, the delivery port of rainwater collecting pit 1 communicates with the water inlet of automatic rinse water strainer 2, and the delivery port of rinse water strainer 2 communicates with the water inlet of clear water reserviors 3 automatically.
Above-mentioned automatic rinse water strainer 2 is to utilize the clear water that self filters out by internal differential pressure self-cleaning screen pack.
In the present embodiment, above-mentioned rainwater flow-discarding device 4 is collected rainwater by the rainwater gutter of the monolateral setting of roofing.
Operating principle of the present utility model is as follows: the initial stage rain water on roof is flowed through and is entered rainwater collecting pit 1 behind rainwater flow-discarding device 4 abandoned streams, rainwater is in rainwater collecting pit 1 behind the collecting precipitation, again through automatic rinse water strainer 2 further impurity screenings, automatically rinse water strainer 2 is to utilize the clear water that comes out that self filters by internal differential pressure self-cleaning screen pack, without any need for extra power.Rainwater enters rainwater clear water reserviors 3 after filtering and stores.
The organic matter of natural rainwater pollutes few, and hardness is low, but because natural dirt at ordinary times falls, drops to the formed early-stage rainwater of roofing and still have certain contaminative.Rainfall runoff has tangible erosion effect, and promptly as a rule, pollutant is to concentrate in the several millimeters rainfall at initial stage.The control early-stage rainwater can effectively be controlled the most of pollutant in every rainfall runoff, and the utility model early-stage rainwater control method adopts the autocontrol early-stage rainwater stream abandoning device.The automatic control flow abandoning apparatus, have the function of automatic switchover rain water drainage pipeline and collection conduit and have and control and regulate the abandoned stream function of blanking time, early-stage rainwater stream abandoning blanking time can automatically prolong when rainy season is frequent, can directly be connected by flange with pipeline, easy for installation, equipment volume is little, saves the space.If the utility model is used for the more frequent area of rainfall in rainy season, the rainwater water quality of collecting is better, and the water project of the rainwater reuse system of the utility model design is only watered for greening and is spilt, lower to water quality requirement, in addition, consider that rainfall randomness is bigger, recovery water source instability, for the regular of purification of water quality facility that avoids rainwater left unused, so the utility model adopts comparatively simple treatment process: enter the collecting pit precipitation menarche of rainwater behind the abandoned stream, the process strainer enters in the clear water reserviors and stores again.Because it is to concentrate at the annex terrace to be provided with that this rainwater is collected reclamation set, simultaneously water supply system can the up mode of giving down of corresponding employing, the utility model system can satisfy the outdoor greening water hydraulic pressure requirement of the first floor, need not to establish in addition the feedwater supercharging equipment and has reduced the investment of equipment and made system more energy-conservation.Owing to utilized rain water collecting system of the present utility model, terrace adopts single sloping draining, and collects rainwater by the rainwater gutter of monolateral setting, has reduced rain leader downspout and outstanding slow-witted pipe, has saved tubing.
