The specific embodiment
Among Fig. 1, color profiling steel plate is adopted in rainwater collecting layer 1, and thickness of slab is 0.5 millimeter, and frame is on the lightweight steel structure frame.Rainwater is collected in rainwater collecting layer 1, flows to low level by a both sides high position, falls into water receiving tank 2.Among the figure, 3. rainwater drain gully; 4. go up manhole; 5. guardrail can supply people's activity, go sightseeing, is provided with water tank in the hurdle; 6. roofing is along ditch; 7. loft front wall or afterwards wall; 8. window; 9. loft side wall; 10. total water tank; 11. lightweight steel structure frame post.
Among Fig. 2, water receiving tank 2 bottom surfaces and total water tank 10 end faces are two-in-one structure, and bottom land has rainwater drain gully 3, water tank inlet 13, water tank maintenance access 14, the horizontal absolute altitude of each mouthful upper surface is: rainwater drain gully 3 is lower than water tank inlet 13, and water tank inlet 13 is lower than water tank access hole 14; Water tank inlet 13 exceeds bottom land partly a small gap, so that drain the ponding of bottom land behind rainy the stopping, the breach size satisfies rainy stopping in 12 hours, and 24 risings exert an influence to sluice to eliminate ponding.Water tank overfall gap 16 is than low 5 centimetres of bottom surface, case top, and water outlet of water tank 17 is higher than 5 centimetres of water tank bottom surfaces, and total water tank 10 inside are divided into sedimentation and filtration case 22 and filtered water tank 23.The upper end of filtered water tank sewage draining exit 18 and sedimentation and filtration case sewage draining exit 21 is with equal at the bottom of the water tank; Rainwater leader 20 direct puncture water tank top board and base plates separate fully with water tank inside; The rainwater that forms more impurity when rainy flows to roofing along ditch by rainwater leader 20.When rainwater was purer, sluice 24 fell to closing rainwater drain gully 3, and the rainwater in the water receiving tank 2 flows in the sedimentation and filtration case 22 through water tank inlet 13, enters filtered water tank 23 through filter screen 19.At the bottom of the screen pack 19 dried up casees 20 centimetres, screen pack is detachable, comes in and goes out for the maintenance of sedimentation and filtration case.Total water tank 10 usefulness steel concretes are cast-in-place, and volume is determined according to the weight capacity in size, intensity and the house of long-term rainfall.
Among Fig. 3, sluice is the water containing container of truncated cone-shaped, make with stainless steel, place valve rubber below the upper end turned welt 30, sluice upper end turned welt 30 external diameters are bigger 2 centimetres than the internal diameter of rainwater drain gully, sluice 31 external diameters suitable for reading are slightly less than the rainwater drain gully, and greater than sluice end opening 35, can enter in the rainwater drain gully smoothly when sluice is fallen; For making the steady falling-rising of sluice, do a space can for the sluice falling-rising.Among the figure, 32. sluice suspension ring, are connected with balance weight by pulley, connection cord totally by 3; 33. sluice sidewall; 34. sluice screen pack; The control valve 36. sluice drips, its effect are that sluice is in the rainwater drain gully, rains when stopping about 12 hours, the water droplet in the container to the top position that sluice is returned to be suspended on drain gully.
Among Fig. 4, flow control device is made up of sluice 24, fixed pulley 27, balance weight 28, collection rain drain bucket 26, connection cord 25, fixed mount 29.Sluice 24 is connected with an end of connection cord 25, and the other end of connection cord 25 is connected with balance weight 28, and connection cord 25 passes fixed pulley 27.Sluice 24 with the equilibrium conditions of balance weight 28 is: when filling 2/3rds water in the sluice 24 and balance weight 28 balances.Water in the sluice 24 is supplied with by collection rain drain bucket 26, perhaps the rainwater of being collected by part rainwater collecting layer is supplied with, collection rain drain bucket 26 has water velocity control valve (not drawing among the figure), and the water yield that flows into sluice 24 should ooze the water yield greater than sluice 24, can determine according to the purity requirement of collecting rainwater.When it does not rain for a long time (general about 12 hours), anhydrous in the sluice 24, sluice 24 is suspended on the top of rainwater drain gully; During it rains, the rainwater that contains more impurity at first flows to roofing along ditch by the rainwater drain gully, the collection rain drain bucket 26 that is located at simultaneously directly over the sluice 24 supplies water to sluice 24, when the water yield in the sluice 24 surpasses 2/3 volume, sluice 24 and balance weight 28 disequilibriums, sluice 24 falls to closing the rainwater drain gully, and rainwater flows into water tank through water tank inlet; Stop the time (general about 12 hours) for a long time when raining, the water droplets in the sluice 24 are to less than 2/3 volume when following, and sluice 24 rises, and the rainwater drain gully reopens.Among the figure, fixed mount 29 is fixed pulley 27 and collection rain drain bucket 26 fixedly.
Fig. 5 is the position relation between reflection rainwater collecting layer 1, water receiving tank 2, total water tank 10, guardrail 5, the roofing 12.The total water tank 10 of total water tank bearing 15 supportings; Guardrail 5 is railing or breast board or enclosure wall; It is 5% to 10% that the slope is put in rainwater collecting layer 1; The water tank height is controlled at 1.6 meters; Water receiving tank 2 bottom surfaces and total water tank 10 end faces are two-in-one structure, perhaps are higher than the end face of total water tank 10; It is suitable for reading that rainwater collecting layer 1 is higher than water receiving tank 2.Among the figure, 14. water tanks maintenance access; 16. water tank overfall gap; 17, water outlet of water tank; 18. filtered water tank sewage draining exit; 37. the light steel of supporting rainwater collecting layer.
