Embodiment 1

[0034] refer to figure 1 , the grid cover 1 is connected with the bucket body 8 through the fixing bolts 3, the anti-vortex device 2 is placed at the bottom of the bucket body 8, the lower end of the bucket body 8 is connected to the short water outlet pipe 12, and the connecting bolt 4 locks the waterproof pressure plate 5 with the waterproof The wing ring 6 and the outside of the bucket body 8 are connected to the heating device 7, and the outside of the heating device 7 is covered with an insulating layer 9, and the outer part of the insulating layer 9 has a protective cover 10, and a power line 11 is drawn from the lower side of the rain bucket.

[0035] In this embodiment, the snow-melting type pressure flow rainwater bucket can adopt a concave stainless steel bucket body, placed below the bottom surface of the rainwater gutter, in the shape of a drum, and the lower part is connected to a short water outlet pipe. Polyurethane foam is used as the insulation layer, and a st...

Embodiment 2

[0038] In this embodiment, the snow-melting type pressure flow rainwater bucket can adopt a concave aluminum alloy bucket body, placed below the bottom of the rainwater gutter, in a cylindrical shape, and the lower part is connected to a short water outlet pipe. The outside of the bucket body is coated with electric heating film. Optionally, in order to achieve a better thermal insulation effect, a lower-density rigid polyurethane foam thermal insulation layer can be arranged on the outside of the bucket body, and the metal protective cover can be arranged on the outer side of the thermal insulation layer.

Embodiment 3

[0040] In this embodiment, the snow-melting type pressure flow rainwater bucket can adopt a concave cast iron bucket body, which is placed below the bottom surface of the rainwater gutter and is cylindrical, and the lower part is connected to a short water outlet pipe. The outer side of the bucket body is connected to the heating pipe through mechanical fixing or a fixing method in the known technical field. The outside of the heating pipe can be provided with a polyurethane foam insulation layer, and the outside of the insulation layer can be equipped with a stainless steel protective cover.

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 [0001] The invention relates to a rain bucket, in particular to a snow melting type pressure flow rain bucket. Background technique [0002] At present, the known pressure flow rainwater bucket mainly consists of a grid cover, an anti-vortex device and a bucket body. Under the designed working condition, the roof rainwater drainage system presents full pipe flow and rapid drainage. However, in the spring and winter handover seasons in the vast northern cold regions of our country, the snow on the roof melts during the day, and the snow water entrains half-melted snowballs, blocking the outlet of the rainwater bucket, and the drainage function of the rainwater drainage system on the roof is seriously lost; Gutters and gutters increase the load on the roof gutter strip area; rainwater overflowing from gutters and gutters affects the use function and product quality of the building; the temperature gradually cools in the evening, and the outdoor temperature dro...
