Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to a roof snow removal device that removes snow by causing snow removal water to flow down in waves from the ridge toward the eaves on a wavy roof surface. .

[Conventional technology]

Conventional roof snow removal equipment includes a water sprinkler pipe or water nozzle installed in the ridge, which sprays hot water or groundwater from the water pipe to remove snow, or a snow removal equipment that installs heater wires on the roof surface or installs a panel heater. There are snow removal devices that are installed and use electrical thermal energy to remove snow, but the former effectively removes snow only near the sprinkler area, but the snow removal effect decreases toward the eaves, so the average amount of snow removal is reduced. The latter has the drawback that it does not remove snow, and the latter is not only expensive to construct, but also increases electricity costs, making it uneconomical and currently not widely used.

Recently, natural snow-melting roofs have been developed that use indoor warm air (exhaust heat from everyday life) to heat the attic and melt the snow, and these roofs have begun to spread, but although they are economical, they do not effectively melt snow due to the lack of thermal energy. If this is not done, it will not be able to cope with large amounts of snow during heavy snowfalls and will not be effective.

[Problem to be solved by the invention]

A technical object of the present invention is to provide a roof snow removal device that solves these drawbacks.

[Means to solve the problem]

The gist of the present invention will be explained with reference to the accompanying drawings.

A water storage section 9 having a channel-like cross section and approximately the same length as the ridge section 2 is provided in the ridge section 2 of the roof 1 having a slope, and a water pipe 3 is connected to this water storage section 9. A water tank 12 is provided, and a wavy roof surface 17 is formed in which concave strips 5 and convex strips 6 are alternately arranged parallel to the ridge portion 2 and gradually lowered along the roof slope. Water stop plate 1 on both sides of 17
5 is erected, a drainage gutter 7 is attached to the eaves part 4 of the wavy roof surface 17, and a drain pipe 8 is connected to this drainage gutter 7.
This drain pipe 8 is connected to the water collection tank 12, water is injected into the water storage part 9 through the water pipe 3, and the water overflowing from the water storage part 9 is made to flow downward sequentially through the grooves 5 and the protrusions 6. This invention relates to a roof snow removal device characterized in that it is configured to use this flowing sewage water to remove snow on a roof 1.

[Effect]

The snow melting water is introduced into the water storage part 9 by the water pipe 3,
The snow melting water that filled the water storage section 9 overflows from the water storage section 9 and flows down to the roof surface. This snow melting water is introduced into the drainage gutter 7, flows down the drain pipe 8, and is stored in the water collection tank 12. The stored snow melting water is introduced into the water storage section 9 again through the water pipe 3.

The snow-melting water first fills the groove 5 closest to the ridge 2, and the snow-melting water overflowing from this groove 5 passes through the tops of the protrusions 6 at appropriate locations and flows down to the next groove 5 below. By repeating this process, a wavy water film is formed on the entire surface of the wavy roof surface 17 and flows toward the eaves part 4, and this wavy running water action ensures that the snow on the wavy roof surface 17 is melted. Become. That is, when snow falls on a dynamic wavy water film, the snow removal effect is higher than when snow falls on still water, and
The snow melting water that overflows from the upper groove 5 to the top of the protrusion 6 to the next lower groove 5 is strengthened by the falling force due to the head difference, and flows downward one after another, and this falling force (Wave energy) and the slight heat generated by the friction between the overflowing water will further enhance the snow-melting effect.

The snow-melting water flowing down the wavy roof surface 17 will not flow down from both sides of the wavy roof surface 17 because of the water stop plate 15, and will surely flow down to the eaves side.

〔Example〕

The roof 1 in the drawing shows a gable roof with slopes on both roof surfaces, and a long and narrow water gutter is adopted as the water storage part 9, and the outflow notch 10 is constant in the length direction of the left and right opening edges of this water gutter. The figure shows a case in which snow melting water is provided at intervals and is caused to overflow from the outflow notches 10 and flow down onto the wavy roof surface 17.

The tip of the water pipe 3 faces the middle of this water gutter, and a water pump 11 is installed in the middle of this water pipe 3, and the other end is connected to a water collection tank 12 on the ground. A pumping pipe 14 for pumping up groundwater with a pump 13 is connected.

Although the drawing shows a case in which a commercially available folded plate roofing material is coated on the roof 1 to form the wavy roof surface 17, a wavy plastic plate may also be used.

Water stop plates 15 are provided at both ends of the wavy roof surface 17 in the drawing to prevent water from spilling out.

The roof 1 may be a horizontal galvanized iron roof or a long tile-stick roof.

In addition, the drawing shows that the drain pipe 8 is connected to the drain gutter 7,
The tip of this drain pipe 8 is connected to a water collection tank 12 to collect snowmelt water into the water collection tank 12, and this snowmelt water is pumped up again and sent to the water storage part 9 through the water supply pipe 3 to be reused as snow melting water. The figure shows the case where

Furthermore, the drawings illustrate a case where an underground return pipe 16 is provided in the drain pipe 8 to return snowmelt water underground.

In the case of using hot water, a heating device such as a boiler, a water heater, or a water heater may be provided in the middle of the water pipe 3 to once heat the snow melting water and then send the water.

Reference numeral 4 in the figure is the eaves part.

〔Effect of the invention〕

Since the present invention is configured as described above, the snow melting water overflowing from the water storage part flows down while forming a wavy running water film on the wavy roof surface, and snowfall can be efficiently melted by this wavy running water action. become.

Furthermore, since this snow-melting water overflows from the upper groove to the lower groove, which has a difference in height, it flows down, and the energy of the waves generated by the falling snow melts more efficiently.

In other words, by applying the principle that snow melting using dynamic water is more effective than snow melting using static water,
In addition, snow is effectively melted by utilizing the falling force of water from the upper groove to the lower groove and the slight heat generated by overflowing water.

As described above, the present invention can efficiently melt snow by flowing snow melting water on a wavy roof surface, and since the snow is melted by dynamic water due to the wavy flowing water action, it is possible to melt snow efficiently by flowing snow melting water on a wavy roof surface. The snow removal effect is superior to snow removal with water, and the entire roof can be evenly removed, and in terms of fuel efficiency, it is necessary to heat the snow removal water with a heating device unless the outside temperature falls below 0°. This makes it more economical than conventional roof snow removal devices that use energy such as oil, gas, or electricity.
