The technical solution adopted in the utility model is: a kind of hydrocone type roof drain, comprise fairing, waterproof pressure ring, bucket body, described fairing is arranged on the described bucket body, described waterproof pressure ring is arranged between described fairing and the described bucket body, described fairing comprises body, soffit at described body is evenly distributed with some blades, and described blade is made up of linear leaf and short blade, wherein linear leaf and the short blade distribution of being separated by.

Described blade is 36, and linear leaf is 12, and short blade is 24, is provided with two short blades between per two linear leafs.

Described outfall is opened in the bottom center of bucket body, forms the gradients of 9 degree between the bottom surface of bucket body and outfall.

Be provided with outside bucket seat at described bucket body top edge, described fairing is fixed on the described bucket seat by screw rod.

Offer connecting hole on described bucket seat, standing screw passes described connecting hole waterproof pressure ring, waterproofing course and bucket body is tightened together.

Described connecting hole quantity is ten, is evenly distributed on the described bucket seat.

On described waterproof pressure ring, be provided with the tooth line of annular.

Upper surface at described fairing body is provided with reinforcing rib.

Outfall bottom at described bucket body is equipped with flange.

Hydrocone type roof drain of the present utility model, by improvement to roof drain, water level before the bucket when adopting unique fairing and sunk type bucket body effectively to reduce operating mode, make this novel roof drain can directly apply to the roofing of various forms, various materials, rainwater has passed through effective rectification of fairing before importing storm-water system, realizes the separation of good carbonated drink, eliminate the negative effect of whirlpool, thereby realized siphon storm-water system high flow rate, the big required condition of flow.

The utility model is described in further detail below in conjunction with drawings and the specific embodiments.

The specific embodiment

As shown in Figure 1, hydrocone type roof drain of the present utility model comprises fairing 1, waterproof pressure ring 2, bucket body 3, extends outward central pocket loop seat 4 at the top edge of bucket body 3, and fairing 1 is fixed on the bucket seat 4 by screw rod 5.Be evenly distributed on the bucket seat 4 offering 6, ten connecting holes 6 of ten connecting holes on the bucket seat 4, standing screw 14 passes connecting hole 6 waterproof pressure ring 2, waterproof roll 21 and bucket body 3 is tightened together.

Shown in Fig. 2-6, fairing 1 comprises body 8, upper surface at body 8 is provided with reinforcing rib 9, soffit at body 8 is evenly distributed with 36 blades, spacing between every blade is 20mm, wherein linear leaf 10 is 12, and short blade 11 is 24, is provided with two short blades 11 between per two linear leafs 10.Rainwater is when flowing into roof drain, at first by fairing 1, the bigger foreign material that are mingled with in the water can be by the blade barrier, foreign material can't enter storm-water system, avoid system pipeline to stop up, and the spacing of blade is 20mm, have the outer shroud that blade that 36 length, moulding differ is evenly distributed on fairing, the rainwater of flowing through can obtain the rectification of blade, and the rainwater fluidised form after the rectification tends towards stability, flow velocity is even, does not produce whirlpool around the operating mode lower blade.When the rainwater degree of depth around the roof drain reached before the bucket of design water level, system can form siphon, and rainwater drains into outdoor with higher flow velocity.

Shown in Fig. 7-9, on waterproof pressure ring 2, have the connecting hole 19 corresponding with connecting hole 6, in order to seal closely, also be provided with annular embossing 13.

Shown in Figure 10-12, bucket body outfall 12 is opened in the bottom center of bucket body 3, and the gradients that form 9 degree between the bottom surface of bucket body 3 and outfall 12 can prevent that to water (flow) direction the bucket body bottom from producing local ponding, improves the water conservancy condition of roof drain; For easy for installation, be adapted at different roofings, can flange 25 be installed in the outfall bottom of bucket body 3.

The installation situation that the utility model is concrete, as shown in figure 13, roof drain is installed in roof panel 20, self-adhesion sealing ring 15, waterproof roll 16 pavings on the bucket seat 4 of bucket body 3, are given as security waterproof pressure ring 2 tightly with set bolt, and make edge sealing with waterproof sealing cream 17 and handle, when adopting non-pre-buried installation, after roof drain installs, use cement mortar or the closely knit filling of other materials around the bucket body 3, and make roofing top board leveling layer 18.
