Description

[Detailed explanation of the idea] [Industrial application field] The present invention relates to a roof snow removal device.

[Conventional technology]

Traditionally, snow was removed by pouring water over the entire surface of the roof or by sprinkling water, but this method
It is not widely used because it causes severe damage to rain gutters, it backs up into the attic when the eaves freeze, and it requires a large amount of snow-melting water, making it uneconomical.

[Problem that the invention attempts to solve]

This idea involves installing a snow-blowing gutter large enough to catch falling snow directly under the eaves, throwing roof snow into the snow-blowing gutter, letting it slide off, and then sprinkling snow-melting water from a sprinkler to eliminate the snow. It is a technical problem to provide a roof snow removal device that has a significantly better snow removal effect and does not damage the roof.

[Means for solving problems]

A snow clearing gutter a is provided close to the lower part of the eaves of the roof 1 and is large enough to catch falling snow in a direction parallel to the eaves edge,
A snow stopper 16 is provided on the outside of this snow-blowing gutter a, protruding upward to a position higher than the eaves, and a watering device 2 for sprinkling water into the snow-melting gutter a is provided above this snow-melting gutter a. Install a drain pipe 3 in the snow gutter a.

[Effect]

Roof snow naturally falls and slides into snow removal gutter a. (A worker may climb onto the roof and throw the roof snow into the snow removal gutter a without waiting for it to fall naturally.) The diagram shows that when the snow detector 9 is activated by the weight of the snow and the switch is turned on, the water is pumped up. The pump is activated and water is sprayed from the water sprinkler 2 in a shower to melt the snow.

This water is mainly well water (groundwater), but in some cases hot water may be used, or household wastewater may be used, or any water with a certain temperature may be used.

Snowmelt water, ie, waste water, is drained to the outside through a drain pipe 3.

In this case, if the snow-blowing gutter a is relatively deep, if the drain pipe 3 is installed by protruding halfway into the snow-melting gutter a, about half of the snow-melting water will remain in the snow-blowing gutter a at all times. Therefore, snow can be melted by storing water if there is residual heat in the water.

Alternatively, a rotating shaft may be provided in the longitudinal direction of the snow-blowing gutter a, and a stirring blade may be provided on this rotating shaft to remove snow while stirring.

〔Example〕

It is a perspective view of a snow-blowing gutter a installed just below the eaves of a single-slope roof 1, and FIG. 2 is an enlarged side sectional view thereof.

A support stand 4 is installed horizontally protruding directly under the eaves, that is, on the outside wall of the house, and a snow-blowing gutter a is installed on this support stand 4, and the outer upper part of the snow-blowing gutter a is extended upward to form a snow stopper plate 16. In line with this, a snow stopper support plate 5 is provided vertically protruding from the outer end of the support stand 4, and a water sprinkler 2 is provided in the lengthwise direction of the inner upper part of the snow stopper support plate 5. There is.

This water sprinkling device 2 shows a case in which a water sprinkling pipe 6 is installed parallel to the eave edge, water nozzles 7 are provided on the water sprinkling pipe 6 at regular intervals, and a cover 8 is attached above the water sprinkling pipe 6. There is.

The snow stop plate 16 may not be formed by extending the outer upper part of the snow clearing gutter a, but the snow stop support plate 5 may act as the snow stop plate 16.

A snow detector 9 that activates a water pump is provided at an appropriate location within the snow-blowing gutter a (one or several locations in relation to the roof), and a drain pipe 3 is connected to the bottom of the snow-blowing gutter a. .

This snow sensor 9 has both a fixed plate 10 and a movable plate 11 pivoted by a shaft 13 against a spring 12, and contacts 14 and 15 of a contact switch are installed inside both of them.
is provided, and the movable plate 11 slides due to the weight of the snow, and the contact point 1
The figure shows a case where the switch is turned on when contact point 4 and contact point 15 come into contact, and the water pump is operated.

Depending on the shape of the roof, a plurality of water pipes 6, such as two or three pipes, may be provided, and the water nozzles 7 may be arranged in a staggered manner to greatly increase the snow removal effect.

[Effect of idea]

This idea is constructed as described above, so the snow-melting gutter a
When roof snow is thrown into the snow melting gutter a and snow melting water such as ground water or hot water is sprinkled from the water sprinkler 2 into the snow melting gutter a, the snow is melted by the thermal energy of the snow melting water and the snow is melted. Since this snow-melting water is continuously sprinkled, it is easy to do snow-melting with good effect in a short period of time.
Since the waste water is sequentially discharged to the outside through the drain pipe 3, there is no overflow and snow can be melted with peace of mind.

In this case, the snow in the snow removal gutter a will be removed immediately,
Instead of being drained as waste water from the drain pipe 3, the snow becomes a shear bed containing a large amount of snow melting water, and the snow is melted by sprinkling snow melting water on this shear bed snow, i.e. snow storage. This provides highly efficient roof snow removal.

In addition, a snow stopper plate 16 is installed upwards on the outside of the snow-blowing gutter a to a position higher than the roof 1, so even if the snow that naturally falls from the roof 1 falls into the snow-blowing gutter a, it will be stopped. Because of the presence of the plate 16, the snow does not jump over the snow-blowing gutter a and falling to the outside, and the snow can be reliably received into the snow-blowing gutter a. (Also, when throwing snow onto the roof 1 into the snow removal gutter a, the snow can be thrown with the snow stopper 16 as the target, and the snow can be thrown into the snow removal gutter a reliably.) Since it does not fall over the snow removal gutter a, it does not damage the windows or walls of neighboring houses, and even if there are pedestrians on the ground, the snow can be removed with peace of mind.

Compared to conventional snow removal methods that run water over the entire surface of the roof or sprinkle water on the roof, this invention can remove snow without damaging the roof, eaves, rain gutters, etc., and is more economical by recycling drainage water. In addition, this snow removal device is ideal for removing snow in densely populated areas where there is no snow dumping site, and by setting the snow detector 9 to the sprinkler device 2, automatic watering is possible. It has excellent practical effects, such as being able to easily remove snow.
