Described rainwater down pipe outer wall offers the slotted eye for inserting rainwater down pipe current divider 4, when described rainwater down pipe current divider is inserted in rainwater down pipe, the outward flange of rainwater down pipe current divider 4 will just be combined closely with rainwater down pipe 1 inwall, and described rainwater down pipe current divider 4 tail ends are connected with mozzle 2.
Described slotted eye comprises strip notch 7 and manhole 8, described strip notch 7 one end are communicated with one end of manhole 8, the thickness of the broadband of described strip notch 7 and rainwater down pipe current divider 4 is suitable, the slightly larger in diameter of described manhole 8 is in the width of strip notch 7, and the total length after described strip notch 7 is connected with manhole 8 perforations is slightly larger than the semicircular plate diameter of rainwater down pipe current divider body 5.Described slotted eye by orifice sealing, is avoided leaking after rainwater down pipe current divider 4, mozzle 2 install.
Described rainwater down pipe current divider 4 comprises by rainwater down pipe current divider body 5, rainwater down pipe current divider tail 6 and retaining ring 9, described rainwater down pipe current divider body 5 is semicircular plate, described rainwater down pipe current divider tail 6 is elongated plates, described rainwater down pipe current divider body 5 is connected with rainwater down pipe current divider tail 6, and described retaining ring 9 is arranged at the surrounding of the base plate that rainwater down pipe current divider body 5 and rainwater down pipe current divider tail 6 surround.
Described rainwater down pipe current divider tail 6 is provided with the fixator and the fixing hole that is arranged at rainwater down pipe current divider tail for fixing rainwater down pipe current divider 4, and described fixator is sheathed on rainwater down pipe outer wall through fixing hole.
Described fixator comprises interior cuff, inner bayonet, outer cuff, outer bayonet and fixing screw thread; Described interior cuff is the semicircular arc that bullion is bent into, inner bayonet is two screw bayonet sockets that are positioned at cuff two ends, the semicircular arc that outer cuff is also bent into for bullion, and form complete circle with interior cuff closure, outer bayonet is two screw bayonet sockets that are positioned at outer cuff two ends, and fixing screw thread is the thread that is positioned at top outside inner bayonet arc.
Described water storage box is the nearer room of each cell distance rainwater down pipe in being arranged at and building a building, and can be arranged at apart from the room in 1 meter to 2 meters of rainwater down pipes.
The rainwater down pipe part flow arrangement that the present embodiment provides, that rainwater flat-top roofing being confluxed by rainwater down pipe current divider is intercepted and captured and shunts out from rainwater down pipe, via water guide pipeline, the rainwater of gained is transported to each floor user water storage box place, to realize the device of rainwater-collecting reuse.
Rainwater down pipe current divider is to be placed in rainwater down pipe inside, and same rainwater down pipe, PVC water conservancy diversion water pipe are combined use, adopts the method for manually damming to intercept and capture top-down part rainwater in rainwater down pipe, and is passed through the member of PVC water conservancy diversion water pipe importing water storage box.Be made up of rainwater down pipe current divider body and rainwater down pipe current divider tail two parts, the design angle value of its normal work is 15 °.
Rainwater down pipe current divider is made up of polystyrene plastics.This density of material is little, quality light, be easy to moulding and processing, is convenient to produce in enormous quantities; Simultaneously this material have and have preferably corrosion-resistant, acid and alkali-resistance, oil resistant, impact resistance and mechanical strength preferably.
To be that it is shaped as half cylindrical in place the most cleverly in design for this member.Because rainwater flows downward along rainwater down pipe inwall in flow process from top to bottom, therefore rainwater down pipe current divider can only intercept wherein a part of rainwater, all the other rainwater can continue along tube wall to dirty.
If install this member on the every floor rainwater down pipe of flat-top corresponding site, be connected with water storage box within doors by PVC water conservancy diversion water pipe simultaneously, just can realize every floor with getting per family part rainwater, will drop down onto the rainwater-collecting of flat-top roofing to the every household of each floor.
Rain water on roof confluxes and enters in rainwater down pipe through earth's surface, rainwater goes downstream in rainwater down pipe, part rainwater is intercepted and captured the rainwater down pipe current divider being positioned in rainwater down pipe, by being imported in water storage box by PVC water conservancy diversion water pipe, in water storage box, collected rainwater is carried out after Simple filter purified treatment, can be by rainwater for toilet flushing, irrigating plant etc.
Shown in Fig. 2, the rainwater conflux direction that in figure, direction shown in arrow is roofing, the about 1346.46m2 of roofing catchment area.This unit building is established 13 rainwater down pipes altogether, and particular location is as shown in black circle in figure.
For guaranteeing that rainwater down pipe current divider body part can put into rainwater down pipe smoothly, make its edge can with the use of combining closely of rainwater down pipe inwall.Ensure again that rainwater down pipe current divider tail can be normally fixing on rainwater down pipe after connecting upper PVC water conservancy diversion water pipe simultaneously, be 30mm according to major diameter water pipe interior diameter, external diameter is the characteristic of 31～33mm approximately, designs round hole size and be about D=32mm on the outer tube wall of rainwater down pipe.Because rainwater down pipe current divider need be packed in rainwater down pipe by rotation mode, can calculate thus theoretical perforate is highly h=80.62mm.Meanwhile, again because rainwater down pipe self exists wall thickness, therefore the height H of design perforate should be slightly larger than theoretical value h, get H=85mm, size is as figure.
Finally explanation is, above embodiment is only unrestricted in order to the technical solution of the utility model to be described, although by the utility model being described with reference to preferred embodiment of the present utility model, but those of ordinary skill in the art is to be understood that, can make various changes to it in the form and details, and not depart from the spirit and scope of the present utility model that appended claims limits.
