(5) specific embodiment
Referring to Fig. 1, initial rain water drainage tank of the present invention is divided into separation chamber 6 and early-stage rainwater collecting chamber 10 two large divisions by a demarcation strip 8 in the pond body 14.The separation chamber be positioned at the early-stage rainwater collecting chamber above, above-mentioned two Room are communicated with separation chamber's manhole 2 and early-stage rainwater collecting chamber manhole 11 upward respectively, manhole is provided with the maintenance cover plate, the lower sidewalls of separation chamber's manhole 2 is communicated with rainwater collection conduit import 1, below with respect to the import of rainwater collection conduit is equipped with coarse rack 3, the base plate of separation chamber, be on the demarcation strip, have at least two water falling holes 13 that communicate with the early-stage rainwater collecting chamber, each water falling hole is connected with an early-stage rainwater partition apparatus 9 respectively, in the separation chamber, have the pod apertures 7 of later stage rainwater above the demarcation strip, thin aperture plate 5 is arranged on it, and be connected to later stage rainwater collecting pit.Smooth and easy for draining, the bottom surface of above-mentioned early-stage rainwater collecting chamber 10 is directed downwards inclination to the manhole of this chamber.Above-mentioned pond body can be steel reinforced concrete pool, glass fiber reinforced plastic pond or masonry and builds the pond by laying bricks or stones.Early-stage rainwater collecting chamber and separation chamber are provided with manhole and maintenance cover plate 2 respectively.Submersible pump 12 in coarse rack 3 in the separation chamber, rainfall gauge stop device 4 and the early-stage rainwater collecting chamber 10 can rise to the ground maintenance at any time.
Referring to Fig. 2, Fig. 3, above-mentioned early-stage rainwater partition apparatus 9 comprise a diameter greater than around the ball float 91 of water falling hole, the water falling hole 13 that the upper end is fixed on demarcation strip, the lower end connect horizontal ball holder 92 and block around ball float four limits four railings 93.Above-mentioned ball float can be styrofoam medicine ball, plastic hollow ball or stainless steel hollow ball.Above-mentioned horizontal ball holder can be horizontal supporting plate, horizontal pressure pin or level holder net.Above-mentioned railing can be solid hopkinson bar or hollow stem.The railing upper and lower end can have screw thread, and its lower end can be by bolt 95 fixed level ball holders, and its upper end can be fastening with the backing plate 94 that is arranged on demarcation strip water falling hole top and bottom by bolt.
The operating principle of early-stage rainwater partition apparatus 9: this device is a ball float abandoned stream partition apparatus, utilize buoyancy of water, when drainage tank is filled with when promptly reaching the abandoned stream volume, ball float with regard on float to position topmost, the water falling hole that rainwater flows into is blocked, thereby realized abandoned stream and collect the partition that flows.In order to guarantee that ball float is not stuck, the strength of enough shutoff water falling holes is arranged simultaneously, adopt large-scale ball-type float, and ball float is limited in the scope that does not have fixed contact, also can move both vertically with being no less than 3 post and rails.Avoid because the deposition of water pollutant and the corrosivity of water are sticked together ball float and post and rail, can not move and lost efficacy with the water surface.For safety and dependable flow more, the abandoned stream partition apparatus more than two covers should be set in each drainage tank inside.
Referring to Fig. 4, Fig. 5, Fig. 6, above-mentioned coarse rack below is provided with rainfall gauge stop device 4, this rainfall gauge stop device is one to put into the pond body of electronic level meter 41 at the bottom of the pond, long 1500 millimeters of this pond body, wide 1000 millimeters, high 700 millimeters, leg 44 is high 200 millimeters, 42, the two underflow holes, underflow hole that have two diameters in the bottom surface and be 30 millimeters are at a distance of 750 millimeters, locate 300 millimeters at every interval to have a diameter be 30 millimeters effluent hole 43 for 100 millimeters at the bottom of the pond body sidewall is apart from the pond.
Rainfall gauge stop device 4 is the basic principle work according to the hydro science orifice outflow.When rainfall stops, also having in the rainwater collection conduit partial discharge constantly to compile, so rainfall stop not represent stopping that rainwater collects.When the rainwater collection conduit has not rained water when flowing, the water tank of this device is a full water, the water tank of this device has the underflow hole and the effluent hole of reservation, by aperture flowing water, with water emptying last in the water tank, the quantity of these apertures and big young pathbreaker determine the emptying time of water in the water tank, thereby obtain certain time delay, electronic level meter in the water tank will provide signal when cistern water level arrives a certain position, prove water tank emptying, and rainwater is collected and stopped.
Referring to Fig. 7, application principle of the present invention: rainwater drops to earlier on ground, the roof, enters the rainwater collection conduit after confluxing, flow into initial rain water drainage tank by the pipeline runoff, enter later stage rainwater collecting pit then, after handling reuse, flow into the rainwater reuse water spot at last.
Referring to Fig. 8, the course of work of the present invention: the principle that adopts volume to separate, will need the part rainfall of abandoned stream to store, again early-stage rainwater and later stage rainwater are separated, the later stage rainwater stores separately.The rainwater of collecting is introduced into the separation chamber, remove bigger impurity through coarse rack, enter the early-stage rainwater collecting chamber by the early-stage rainwater partition apparatus of installing on the demarcation strip, when the water level of initial stage rainwater collecting chamber rises to maximum abandoned stream volume, the early-stage rainwater partition apparatus will be closed the water falling hole on the demarcation strip automatically, and the later stage rainwater will flow to later stage rainwater collecting pit by pod apertures through fine fack.The rainwater of early-stage rainwater collecting chamber misses municipal storm-water drainage peak through the storage of certain hour after rain stops, be discharged to municipal Storm Sewer Network by the submersible pump that is arranged at the bottom of the pond, or replenish nature or landscape water body nearby.
The most suitable relatively large rainwater catchment system system of the present invention, whole early-stage rainwater collecting pit is structure, generally should adopt steel concrete to build.In concrete engineering, the volume of collecting chamber, separation chamber, size and scale and rainfall gauge stop device and abandoned stream partition apparatus scale and number needs will specifically be calculated definite.
