Abstract
The invention discloses a snow-melting pressure flow rainwater hopper. The snow-melting pressure flow rainwater hopper comprises a hopper body, a grid cap and a counter-vortex device, wherein the grid cap is arranged above the hopper body; the counter-vortex device is arranged at the bottom of the hopper body; and the hopper body is provided with a heating device. The snow-melting pressure flow rainwater hopper disclosed by the invention can effectively and rapidly drain water, in particular in winter or at the end of winter and the beginning of spring. After an electric power supply of the snow-melting pressure flow rainwater hopper is switched on, the outlet of the rainwater hopper is not frozen even though outdoor temperature is below zero and the drainage function of the rainwater hopper is kept normal.
Description
Technical field
The present invention relates to a kind of roof drain, relate in particular to a kind of snow-melting pressure flow rain hopper.
Background technology
At present, known pressure current roof drain mainly is made up of grill cover, anti-vortex device and bucket body.Under the design work state, the rain water on roof drainage system presents the quick draining of full-section pipe-flow.But, in spring of the vast north cold area of China, winter handing-over season, daytime the roofing snow melting, snow-broth is carried the snow group of partly melting secretly, blocks the roof drain outlet, the drain function of the drainage system against rain of roofing is seriously lost; Rainwater fills with gutter, eaves gutter, has strengthened the load of open valley belt-like zone; The rainwater that gutter, eaves gutter overflow influences the function of use and the product quality of building; Temperature is gradually cool at dusk, and the back outside air temperature drops to below 0 ℃ at nightfall, and the rainwater of thawing begins again to freeze again; Frozen-thaw process back and forth can form suspension icicle not of uniform size or ice curtain in the eaves gutter outer, have serious potential safety hazard; In case fall, possible threat to life.
Therefore; In order to guarantee that the pressure current roof drain is in the cold district reliability of applying; Avoid in spring, winter handing-over season, snow-broth is carried the snow group of partly melting secretly and is blocked the roof drain outlet, causes the serious consequence of drain function forfeiture of the drainage system against rain of roofing; Fill up this great functional defect of usual pressure stream roof drain, need a kind of snow-melting pressure flow rain hopper.
Summary of the invention

The present invention solves its technical problem and adopts following technical scheme:
The disclosed snow-melting pressure flow rain hopper of the present invention comprises bucket body, is installed in the grill cover of said bucket body top and the anti-vortex device that is arranged on said bucket body bottom, and said bucket body is provided with heater.
In a preferred embodiment of the invention, said heater comprises heating cable, and said heating cable is wrapped in the outside of said bucket body.
In another preferred embodiment of the present invention, said heater comprises Electric radiant Heating Film, and said Electric radiant Heating Film is arranged on the outside of said bucket body.
In another preferred embodiment of the present invention, said heater comprises heating tube, and said heating tube is fixed on the outside of said bucket body.
In a preferred embodiment of the invention, said heating cable comprises insulating layer, be arranged on the inner conducting polymer of said insulating layer, and two parallel plain conductors that connect with said polymer.
In a preferred embodiment of the invention, said bucket body is a up concave type.
In a preferred embodiment of the invention, said snow-melting pressure flow rain hopper further comprises the waterproof pressing plate that is arranged on said grill cover and said bucket body junction.
In a preferred embodiment of the invention, said snow-melting pressure flow rain hopper further comprises the anti-hydrofoil ring that is arranged on said waterproof pressing plate below.
In a preferred embodiment of the invention, the arranged outside of said heater has insulation layer.
In a preferred embodiment of the invention, said insulation layer is processed by polyurethane foam.
In a preferred embodiment of the invention, the arranged outside of said insulation layer has protective cover.
The draining effectively apace of the disclosed snow-melting pressure flow rain hopper of the present invention; Particularly in the winter time or the season of Winter-Spring handing-over, open the power supply that snow-melting pressure flow rain hopper is housed, even outside temperature is lower than subzero; The certain temperature range that also can keep the roof drain bucket body; Thereby the outlet opening of roof drain also can not frozen, and snow-broth flows unobstructed, and the roof drain drain function is kept normally.Therefore; In the roof drainage system of cold district, use the disclosed snow-melting pressure flow rain hopper of the present invention, can prevent effectively that snow-broth from freezing in roof drain; Keep the outfall draining unobstructed; Keep the normal drain function of roof drainage system, guarantee building and personal safety, create a pleasant ecological environment.
