Description

Block-proof type roof drain

Technical field

The present invention relates to civil engineering field, more particularly to a kind of block-proof type roof drain.

Background technology

Roof drain is the guider for discharging roof ponding, and the rainwater ponding of general roofing enters storm sewer by gutter Porch, and roof drain is just provided in the porch, its mouth area is larger, is easy to rainwater to enter.

Roof drain has flow straightening grid device, can exclude rain water on roof rapidly, and grid has rectified action, avoids the formation of excessive Vortex, water level before stable bucket, reduce aeration and exclude rain water on roof, snow-broth rapidly, and can effectively stop compared with bigger material.

But due to being all the flowing flux of up/down perforation in roof drain, when the rainy day, descend slowly and lightly in some trees of roofing Leaf or branch can be flowed into roof drain through gutter with rainwater, but due to be connected to the downpipe aperture ratio below roof drain compared with It is small, and some downpipes are not what straight line was set, therefore blocking is easily caused, draining is influenceed, and dredge also cumbersome.

The content of the invention

The technical problem to be solved by the invention is to provide a kind of block-proof type rainwater that debris can be isolated and removed Bucket.

In order to solve the above-mentioned technical problem, the present invention is achieved by the following technical solutions：A kind of block-proof type roof drain, Including roof drain body, drain gully is provided with the top of the roof drain body, bottom is provided with the joint of connection drain gully, institute State and the bushing identical with its size is provided with drain gully, pass through pin close to the side of roof drain body front end face on the bushing Axle is movably connected on roof drain body, and the side the center portion thereof position of roof drain body rear end face is provided with what is raised up Connect ring；The front end face centre of the roof drain body is provided with support, is provided with directive wheel on the support, on directive wheel Guide groove in be provided with bracing wire, one end of the bracing wire, which is fixed on, to be connect on ring, and the other end hangs in the lower section of directive wheel, and should End is close to ground.

Preferably, the limiting card for supporting bushing is provided with the internal face of the drain gully.

Preferably, being provided with spacing hole on the support, the spacing hole is located at the underface of directive wheel, and the other end hangs down Fall the bracing wire in the lower section of directive wheel to be located in spacing hole.

Preferably, the guide groove bottom land at the top of the top and directive wheel for connecing ring is in same level height.

Preferably, corresponded on the bushing at left and right sides of roof drain body and the side of rear end face be provided with it is upward Flange is raised.

Compared with prior art, the present invention is advantageous in that：This block-proof type roof drain is simple in construction, by rain The oral area of bucket body sets the bushing that can be overturn to realize the isolation of debris, prevents roof debris enters in roof drain body from blocking up Firmly downpipe, and be isolated in the debris above bushing and can be removed from bushing, it is easy to the normal of roof drain to dredge, operation side Just.

Embodiment

The present invention will be described in detail with reference to the accompanying drawings and detailed description.

A kind of block-proof type roof drain shown in Fig. 1, Fig. 2 and Fig. 3, including roof drain body 1, the top of the roof drain body 1 Portion is provided with drain gully 3, and bottom is provided with the joint 2 of connection drain gully 3, is provided with the drain gully 3 and is coincide with its size Bushing 4, roof drain body 1 is movably connected in by bearing pin 5 close to the side of the front end face of roof drain body 1 on the bushing 4 On, be provided with close to the side the center portion thereof position of the rear end face of roof drain body 1 raise up connect ring 8, in order to be carried out to bushing 4 Support, the limiting card 11 for supporting bushing 4 is provided with the internal face of the drain gully 3；The front end of the roof drain body 1 Face centre is provided with support 6, is provided with directive wheel 7 on the support 6, the guide groove bottom land at the top of directive wheel 7 with The top for connecing ring 8 is in same level highly, motion stabilization between guarantee bracing wire 9 and directive wheel 7, the guide groove on directive wheel 7 Bracing wire 9 is inside provided with, one end of the bracing wire 9, which is fixed on, to be connect on ring 8, and the other end hangs in the lower section of directive wheel 7, and the end Close to ground；In order to limit the position of bracing wire 9, prevent it from being come off from directive wheel 7, set on the support 6 limited Position hole 10, the spacing hole 10 is located at the underface of directive wheel 7, and the bracing wire 9 that the other end hangs in the lower section of directive wheel 7 is located in In spacing hole 10.In order to prevent rainwater from being flowed away from the top surrounding of roof drain body 1, roof drain body 1 is corresponded on the bushing 4 It is raised that the left and right sides and the side of rear end face are provided with upward flange.

In use, roof drain body 1 to be arranged on to the underface of open valley water inlet, the top surface of roof drain body 1 is extremely The distance between water inlet is more than the width of the top drain gully 3 of roof drain body 1, from upper on the joint 2 of the lower section of roof drain body 1 Connect the downpipe of respective numbers successively under.After installation terminates, treat rainy day, rainwater flows into roof drain from the water inlet of gutter Body 1, the bushing 4 on the top drain gully 3 of roof drain body 1 keep apart the debris being entrained in rainwater, and rainwater is from bushing 4 On small opening enter in roof drain body 1, and flowed out by downpipe, because the surrounding of rainwater all 1 is provided with higher than bushing 4 Flange is raised, and therefore, the rainwater flowed out from drain gully 3 will not be flowed to outside roof drain body 1.When have accumulated one on bushing 1 After fixed debris, as shown in figure 4, the vertically termination of bracing wire 9 immediately below roof drain body 1 is pulled, due to the other end of bracing wire 9 Connecing on ring 8 on bushing 4 is fixed on, in the presence of the guiding of directive wheel 7 and bearing pin 5, one end of bushing 4 is dug up and down, is led to Cross bracing wire and shake the debris on bushing 4 can be flicked back and forth, so as to ensure that bushing 4 realizes self-cleaning function, enable bushing 4 It normal use, will not be blocked because of debris, it also avoid debris and block downpipe, ensure that downpipe can long-term normal use.

This block-proof type roof drain is simple in construction, by setting the bushing 4 that can be overturn real in the oral area of roof drain body 1 The isolation of existing debris, prevent roof debris enters in roof drain body 1 from blocking downpipe, and be isolated in the debris of the top of bushing 4 It can be removed from bushing, be easy to the normal of roof drain to dredge, it is easy to operate.

It is emphasized that：It the above is only presently preferred embodiments of the present invention, not the present invention made any formal Limitation, every any simple modification, equivalent change and modification for being made to above example of technical spirit according to the present invention, In the range of still falling within technical solution of the present invention.
