As shown in Figure 1, the external form of middle base 20 is similar to base 10, and is same, the horizontal expansion to have a transverse slat 21 in the bottom, and the top is provided with breach 22, and vertical wall root edge hollow out is provided with several outfall 23, middle base 20 central authorities are a big frame mouth 24, can provide footstock 30 to follow this big frame mouth 24 and stretch out from inside to outside.As shown in Figure 1, footstock 30 bottoms are laterally expanded and to be provided with a transverse slat 31, and the top is provided with breach 32, and top central authorities are provided with a screw 33, after the big frame mouth 24 that middle base 20 central authorities are followed on footstock 30 tops passes, can be attached at a floating drum 40 by a screw 51 lockings.The structure of described floating drum 40 under the present embodiment, for sealing composition in conjunction with a Sheng dish 42 with a lid 41, preferred embodiment for its lid 41 around side edge part be provided with bulge loop 43, the inside wall of Sheng dish 42 is provided with chase 44, its bulge loop 43 and chase 44 can mutually embedding group be fixed and are the sealing shape.When along nail hole 12 base 10 on following closely admittedly on ground by nail 50 the drowning shower nozzle that can adjust the water yield automatically of the present invention, the direct cover cap of shower nozzle 60 (shown in Figure 4) that can be fallen into water in drain hole place on original attic balcony is lived.
Consult shown in Figure 4ly, the present invention is fixed on after the drain hole place by nail 50, as runs into when raining, and under the less situation of rainfall, a small amount of rainwater can be discharged rainwater smoothly by the outfall 23 formed passages of base 10 bottom outfall 13 and middle base 20 bottoms; At this moment, the water capacity that goes out of the runner that connected of each outfall 13,23 is the water capacity that goes out less than original drowning shower nozzle 60.
Consult shown in Figure 5, when running into rainfall more for a long time, aforementioned each outfall 13,23 connect the total amount that rainwater that water capacity can't bear the big force of rain is fallen that of runners, therefore begin to form the ponding state then on the ground, attic balcony, and this moment need know each its drain hole place, attic balcony, building also just apace water conservancy diversion go out rainwater, land rainwater is on the ground let out in feasible each gutter that rest on the ground ceaselessly wash with watercolours, and be in the full state that closes of displacement, when the force of rain bigger this moment, the road surface in its low-lying area has had the situation of local highway section ponding to take place, and drowning nozzle structure of the present invention, promptly form the ponding state because of ground, attic balcony, so continue to keep original setting by each outfall 13,23 go out water capacity with an amount of draining, avoid descend apace on the ground gutter of a large amount of rainwater with the attic balcony, to prevent that the ponding situation is more serious on the road surface.
As Fig. 3, shown in Figure 5, its rainfall is obviously discharged the state of the water yield greater than the shower nozzle that falls into water, therefore the rainwater water level that stockpiles on the attic balcony just raises gradually, when the water level rising reaches floating drum 40 positions, its floating drum 40 descends naturally and drives footstock 30 and up raise, make and utilize the transverse slat 31 on the footstock 30 that middle base 20 top end breach 22 are stopped up, reduce the water yield that drops to ground, prevent to cause the situation of ponding on the bottom of the building road surface to take place.Under the water level of certain altitude, the breach 14 on base 10 tops still opens wide with discharge water, can avoid attic balcony ponding seriously too much.
As shown in Figure 6, when rainfall strengthens and is lasting, when the shower nozzle discharge water yield of falling into water can't be born more, related footstock 30 also raise after its floating drum 40 raise, therefore the transverse slat 31 of footstock 30 bottoms then blocks the breach 22 on middle base 20 tops, and the transverse slat 21 of middle base 20 bottoms is also blocked the breach 14 on base 10 tops, when the outfall 23 on the middle base 20 bottom vertical walls is increased to end of travel, will be covered by the shield on the base 10 15, therefore the outfall 13 of base 10 bottoms and breach 32 water outlet on a small quantity on footstock 30 tops have only been kept, when running into that so a large amount of forces of rain is fallen, ponding already on the road surface everywhere, thereby design concept of the present invention is that a part of rainwater is persisted on the balcony of each floor, after treating that the bottom of the building surface gathered water disappears, make the rainwater on the attic balcony be expelled to ground fast again, the gradualness water discharge method of trading space for time, thereby when effectively avoiding road surface in the community to meet violent stormwater falling the problem of floods.
In addition, consult Fig. 4 Fig. 6 to shown in, similarly, drowning shower nozzle of the present invention is after the force of rain is gradually had a rest, it is former to drain the water away according to the outfall 13 at base 10 bottoms places and the breach 32 on footstock 30 tops, and after drawdown caused floating drum 40 to be reduced to middle base 20 height, the expression rainfall was less than displacement, thereby its transverse slat 31 promptly forms open state because of floating drum 40 highly descends, and ponding can be discharged along these breach 22 places on middle base 20 tops to accelerate the velocity of discharge.Water level more descends when floating drum 40, even the breach 14 on base 10 tops also can be opened wide, and the ponding of attic balcony is drained fully.
Consult Fig. 7, shown in Figure 8, in another preferred embodiment of the present invention, for will also being provided with floating drum on the middle base 20a at intermediate altitude place, make and himself also can have the function of floating automatically, it is changed in the present embodiment, on the middle base 20a outside, be provided with a mezzanine space 25, the mezzanine space bottom is a blind end, and the mezzanine space top can seal, and also can be the design as the figure open end, because of floating drum 40 width of upper end scope greater than middle base 20a, even therefore rain also unlikely water inlet in this mezzanine space 25 greatly, so the setting of its mezzanine space 25, making has also had certain buoyancy when middle base 20a itself runs into the ponding state.So as shown in Figure 8, when water level rose to a certain height, middle base 20a just can rise, it need not rely on the effect that just has lifting when footstock 30 need rise to end of travel.After water flooding surpasses the height of footstock 30, the set mezzanine space 25 of its middle base 20a also floods into rainwater, when water level disappears, present embodiment can have the function of quickening decline floating drum 40 height, therefore represent on its footstock 30 water outlet breach 32 and the water outlet breach 22 on the middle base 20a can open wide more quickly, help the eliminating speed of ponding.
Present embodiment notes, the weight when floating drum 40 designed buoyancy need greater than interlayer 25 filled with water just can be when the ponding height be higher than floating drum 40, but lifting middle base 20a.
As shown in Figure 9, the structure of another embodiment of the present invention can be provided with button hole 45 on this floating drum 40, and the top of footstock 30 is convexly equipped with a coak 34, and coak directly embeds with button hole and combines.
Each base 10, middle base 20 and the 20a shown in the various embodiments of the present invention and the vertical wall of footstock 30, the smooth demoulding when making things convenient for plastic rubber ejaculate molding to make, so its vertical wall system can be set as the shape that slightly has gradient, like this, can in the uphill process of middle base 20,20a and footstock 30, provide sliding effect comparatively smoothly.
Moreover, size and quantity or its form that outfall 13,23 breach are established on the base 10 and place, middle base 20 bottom, all unrestricted, promptly this place possesses the function that also can have the discharge rainwater under a small amount of rainwater generation situation, it promptly is emphasis of the present invention, be positioned at simultaneously on the base 10 and the breach of middle base 20 top ends, its size and quantity are also unrestricted, can need the annual mean rainfall of each department and decision during fabrication.Breach 32 gross areas of footstock 30 can prevent effectively that ponding is seriously too high, overflow in staircase avoiding.Simultaneously for to make floating drum 40 have the function of lifting, so it is also can be by the bottle blowing process one-body molded to be one to be the cylindrical shell of sealing state, it is attached on the pedestal of lifting, has to adjust the function that changes water outlet breach sizes values.
