Specific embodiment
Below in conjunction with attached drawing, invention is further described in detail.
As depicted in figs. 1 and 2, a kind of roof discharge structure, including roof matrix 1 and sewer pipe 2, in sewer pipe
2 upper end is provided with floor drain apparatus 3, and floor drain apparatus 3 includes inlet and outlet, and the upper end of fore-edge and sewer pipe 2 connects out
Logical, water inlet is arranged in the horizontal direction, and water inlet is provided with filter plate 4, and offer on roof matrix 1 for drawing
Lead the sluice way 5 that rainwater flows to water inlet；When rainy, the ponding and fallen leaves of roof flow to water inlet along sluice way 5, heap of falling leaves
Lower section of the product before filter plate 4, the filter plate 4 being vertically arranged avoid the mesh fallen leaves on completely plugged filter plate 4, improve building
The draining stability on top.
As shown in Figures 2 and 3, water storage tank 6, the depth of water storage tank 6 are provided in roof matrix 1 and before being located at filter plate 4
Greater than the depth of sluice way 5, and it is additionally provided with holding tank 9 on roof matrix 1, is provided between holding tank 9 and water storage tank 6
Connectivity slot 8, and be provided in water storage tank 6 and sweep impeller 10, sweep the rotation setting of impeller 10；When rainwater and fallen leaves are flowed along sluice way 5
When moving into water storage tank 6, the rotation of impeller 10 is swept in driving, so that the fallen leaves in water storage tank 6 are constantly pushed into connectivity slot 8, and
Into in holding tank 9, fallen leaves is avoided to accumulate before filter plate 4, promotes the stability of roof drainage efficiency.
As shown in Figures 2 and 3, include shaft 102 and sweep impeller 101 wherein sweeping impeller 10, in filter plate 4 and roof matrix
1 opposite end is provided with fixation hole, and the both ends rotation of shaft 102 is plugged in fixation hole, circumferentially-spaced in shaft 102 to set
It is equipped with the width that several width swept impeller 101, and sweep impeller 101 is greater than sluice way 5, so that rainwater is flowed along sluice way 5
When, for rainwater from when falling in water storage tank 6 in sluice way 5, impeller 101 is swept in rainwater promotion, so that the rotation of impeller 101 is swept, it is real
Now sweeping impeller 101, constantly rotation understands the fallen leaves before filter plate 4 in the rainy day, guarantees the stability of roof draining.And sweeping leaf
One end of plate 101 towards filter plate 4 offers limiting slot, and limiting slot extends along the width direction for sweeping impeller 101, in limiting slot
Brush body 111(has been plugged and fixed as shown in connection with fig. 4), the side kind of brush body 111 towards filter plate 4 is implanted with bristle 112, brush body 111
Cleaning brush 11 is constituted with bristle 112, while sweeping the rotation of impeller 10, so that bristle 112 will adsorb and the fallen leaves on filter plate 4
It brushes away, promotes the stability of roof draining.
And ball 103 is embedded with the both ends of shaft 102 are circumferentially-spaced, ball 103 is connected to the inside of fixation hole, rolling
Pearl 103 reduces the frictional force that both ends receive when shaft 102 rotates, and improves the stability for sweeping the rotation of impeller 10, while wherein
It sweeps impeller 101 and is provided with non-porous flow-stopping plate 1011 close to the side of sluice way 5, so that the stable promotion of rainwater sweeps 10 turns of impeller
It is dynamic, and the leakage board 1012 that impeller 101 is provided with several holes close to the side far from sluice way 5 is swept, reduction sweeps 101 turns of impeller
The resistance received in intake chamber when dynamic further improves the stability for sweeping the rotation of impeller 10.
As shown in Figure 2 and Figure 5, the connectivity slot 8 between holding tank 9 and water storage tank 6 is obliquely installed, and connectivity slot 8 is close to product
One end of sink 6 is lower than close to one end of holding tank 9, avoids ponding from flowing in holding tank 9 along connectivity slot 8 and causes holding tank 9
Rainwater overflows, and deduction holding tank 9 collects the stability of fallen leaves.Shutter 7 is hinged on roof matrix 1 simultaneously, shutter 7 hides
It is blocked in the top of holding tank 9, and extends to water storage tank 6, avoids then directly dropping down onto holding tank 9, also rainwater is flowed along shutter 7
It moves into water storage tank 6, and is embodied as sweeping the purpose of the offer power of impeller 10.
And loading plate 12 is set in holding tank 9, and fallen leaves are piled up on loading plate 12, in 12 horizontal direction of loading plate
Connecting rod 13 is provided between opposite end and shutter 7, it is hinged between 13 lower end of connecting rod and loading plate 12, in connecting rod
13 upper end is hinged with slide 131, and 7 lower end of shutter offers sliding slot 71 along its length, and the sliding of slide 131 is embedded at
In sliding slot 71, and it is fixed with handle on shutter 7, after needing to rain, pull handle, so that shutter 7 rotates, connection
Bar 13 drives loading plate 12 to rise, and loading plate 12 takes the fallen leaves in holding tank 9 out of, realizes the purpose cleared up holding tank 9.
The working principle of the present embodiment is:
When raining, rainwater drives fallen leaves along the trickling of sluice way 5 into water storage tank 6, and rainwater is when falling in water storage tank 6, rainwater
Water fender is hit, so that sweeping the rotation of impeller 10, impeller 10 is swept and the fallen leaves in water storage tank 6 is pushed in connectivity slot 8, constantly pushing away
During dynamic fallen leaves, so that fallen leaves are finally piled up in holding tank 9, the situation of stopped up with fallen leaves filter plate 4 is avoided, so that building
The rainwater on top smoothly enters drainage pipeline from floor drain ontology, promotes the stability of roof drainage efficiency.
This specific embodiment is only explanation of the invention, is not limitation of the present invention, those skilled in the art
Member can according to need the modification that not creative contribution is made to the present embodiment after reading this specification, but as long as at this
All by the protection of Patent Law in the scope of the claims of invention.
