A kind of siphon drainage roof drain, including roof drain chassis 3 are equipped with pod 6, institute on the roof drain chassis 3 Stating pod 6 includes baffle liner 601, sets that there are two location holes 602 on the baffle liner 601, and 601 lower end of baffle liner is fixed There are several deflectors 603, circumferentially array, 601 upper surface of the baffle liner welding are formed with several water conservancy diversion to the deflector 603 Slot 604, for the opening of the diversion trench 604 towards outside, mutual angle is 30 degree, and the baffle liner is peviform, edge Height, inner ring is low, in certain tilt angle.3 lower end of roof drain chassis is equipped with downpipe 1, the downpipe 1 and rainwater Bucket is equipped with washer 2 between chassis 3, is compressed between the downpipe 1 and roof drain chassis 3 by bolt 9, the roof drain chassis 3 side is connected with the steel plate gutter 4 being connected to aforementioned roof drain chassis 3 along wall setting.The roof drain chassis 3 with lead It is equipped with waterproofing protection structure between stream cover 6, including the waterproof layer 8 being arranged on the roof drain chassis 3 and is arranged described The stainless steel pressing ring 7 of 8 top of waterproof layer, for acting on 3 main body waterproofing protection of roof drain chassis.The stainless steel pressing ring 7 Including in-flanges 701 and flanging 702, it is fixed between the in-flanges 701 and aforementioned waterproof layer 8, in the utility model Stainless steel pressing ring 7 changes tradition in such a way that outer ring is fixed, and is changed to inner ring and fixes, and extends the laying of waterproof layer 8 Area is improved to compress and bond dual mode by traditional single compression, and the waterproof layer 8 is by aforementioned stainless steel pressing ring 7 In-flanges 701 rises, extends at the flanging 702 of aforementioned stainless steel pressing ring 7.The utility model further includes electric heating assembly, packet Include the terminal for being fixed on the heater 11 of aforementioned 3 upper end side of roof drain chassis, being fixed in the middle part of aforementioned 3 lower end of roof drain chassis The set of external member 10, the heat lead 12 and the connection heat lead 12 and heater 11 drawn by the terminal suite 10 Pipe 14.The electric heating assembly for coping with ice and snow weather, caused by preventing because of ice and snow weather the ice and snow of downcomer etc. freeze, Phenomena such as blocking, accumulating prevents the icy water melted to be stranded in gutter.System provides appropriate heat by detecting to ice and snow Amount, prevents the generation of ice and snow freezeout.

The specific working principle of the utility model is as follows: siphonage is utilized, when encountering precipitation, due to baffle liner 601 For peviform, edge is high, and inner ring is low, and rainwater just because gravitional force collects along diversion trench 604 to the inner ring of baffle liner 601, leads to Setting rectifier 5 is crossed, so that rainwater is rectified before entering storm-water system, is obtained to greatest extent by air insulated in rainwater Except exhaust system, full-section pipe-flow is formed for system, condition is provided.At rainfall initial stage, rainwater just collects, the depth of water before roof drain Less, air entrance is not can effectively prevent in roof drain, its fluidised form is partly-filled pipe-flow at this time, and air water reverse flow, this stage is Gravity stream；With the development of heavy rain, the more poly- rainwater the more, and the depth of water before roof drain chassis 3 increases, and air enters increasingly It is few.Desultory full-section pipe-flow is formed in pipeline and mixes bladdery two phase flow, and the depth of water before roof drain chassis 3 reaches certain After height, there is no air incorporations, and full packages pressure fluidised form is consequently formed.It, can be real by the control of caliber, difference in height to pipeline Now to the control of rainwater fluidised form in pipeline, so that the system most of the time all works in the fluidised form of siphon pressure full-section pipe-flow, so that Negative pressure is formed inside pipeline, effect of the water surface by pipeline internal and external pressure difference before roof drain increases the flow and stream of pipeline Speed, to enhance the drainability of storm-water system.It is the working principle of the utility model above.

As described above, although the utility model has been indicated and described referring to specific preferred embodiment, it must not It is construed to the limitation to the utility model itself.In the spirit and scope for not departing from the utility model that appended claims define Under the premise of, it can be made a variety of changes in the form and details.
