Description

Technical Field

[0001] The invention relates to the technical field of roof gutter snow guards, in particular to a metal roof gutter outer snow melting snow guard. Background Art

[0002] Metal roof refers to a roof made of metal materials, which has the advantages of light weight, easy installation, and durability. Due to the heavy snowfall in the north in winter, the cold weather makes it difficult for the snow to melt and accumulate in the drainage gutter, affecting drainage;

[0003] In order to keep the snow out of the drainage ditch, the existing roof is usually equipped with a snow guard at a distance of 500-1000mm from the drainage gutter. However, when the temperature is low, the snow outside the snow guard melts very slowly, resulting in the long-term accumulation of snow on the roof, which will exert a large downward pressure on the roof panel. In the long run, it will cause certain extrusion damage to the structural layer under the roof panel. Therefore, it is urgent to design a snow-melting snow guard outside the metal roof gutter to speed up the melting of snow.

[0004] The information disclosed in this background technology section is only intended to enhance the understanding of the overall background of the invention and should not be regarded as an acknowledgment or any form of suggestion that the information constitutes the prior art already known to a person skilled in the art.

[0028] The following points are worth noting:

[0029] 1. The width of each lower snow guard 17 is set to 80 mm, and the distance between the bottom of each lower snow guard 17 and the top of the aluminum-zinc-magnesium corrugated steel plate 2 is set to 25 mm.

[0030] 2. The gutter body 1 is composed of the gutter and part of the roof panel, and the aluminum-zinc-magnesium corrugated steel sheet 2 is fixedly installed on the roof panel, and the spacing between the aluminum-zinc-magnesium corrugated steel sheet 2 and the gutter is set to 500-1000mm.

[0031] 3. The upper snow guard 3 is made of L-shaped aluminum alloy profile, which can also serve as a supporting beam for the lower snow guard 17. Compared with the previous use of square steel as the keel of the snow guard, the weight of the snow guard is reduced, thereby effectively reducing the cost.

[0032] 4. The heat conduction mechanism includes two U-shaped fixings 18 fixedly installed on the sides of the upper snow guard 3, and a snow-melting electric heating cable 19 is fixedly installed between the two U-shaped fixings 18. When there is a lot of snow blocked on the snow guard, the snow-melting electric heating cable 19 will work and generate heat, thereby heating the snow guard, and the snow on it can be heated, so that the snow can be melted quickly to avoid snow accumulation.

[0033] 5.

The accumulated snow passing through the lower snow shield 17 will fall on the plurality of bearing plates 7. When the accumulated snow reaches a certain weight, the bearing plate 7 will be pressed to deflect downward, and the accumulated snow will be poured out. When the upper bearing plate 7 deflects downward, the plurality of snow-breaking rods 8 at the lower part of the bearing plate 7 will be inserted into the accumulated snow on the lower bearing plate 7, so that the accumulated snow can be squeezed and crushed, thereby reducing the volume of the accumulated snow and making the accumulated snow dispersed and easier to melt.

The heat transfer component includes a heat-conducting rod 4 fixedly installed in the gutter body 1, and the upper end of the heat-conducting rod 4 is fixedly installed in the aluminum-zinc-magnesium corrugated steel plate 2. Heat transfer rods 5 are fixedly installed between the heat-conducting rod 4 and the multiple fixed blocks 6 and the snow guide inclined plate 9. Part of the heat generated by the snow-melting electric heating cable 19 when working will be transferred to the aluminum-zinc-magnesium corrugated steel plate 2 through the upper snow guard plate 3, the snow guard rod 16, the lower snow guard plate 17, and multiple matching steel connecting clamps 13, and will be transferred to the multiple bearing plates 7 and the snow guide inclined plate 9 through the heat-conducting rod 4 and the multiple heat transfer rods 5, that is, the snow on the multiple bearing plates 7 and the snow guide inclined plate 9 will be heated, thereby accelerating the melting of the snow.

[0036] It is further explained that the above-mentioned fixed connection should be understood in a broad sense unless otherwise clearly specified and limited. For example, it can be welding, gluing, or one-piece molding, etc., which are conventional means well known to those skilled in the art.
