Description

[Detailed description of the invention] [Industrial application field] The present invention is a running water type roof snow removing device that melts snow by causing snow melting water to flow down the roof surface in a wave pattern from the ridge toward the eaves. This is related to.

[Conventional technology]

Conventional roof snow removal equipment includes water pipes and water nozzles installed in the roof ridge, and snow removal equipment that sprays hot water or groundwater from the water pipes to remove snow, heater wires, and panel heaters. There are snow removal devices that use electrical thermal energy to remove snow, but the former damages the roof quickly, and there is also the risk of water leakage. There are drawbacks such as the amount of snow melting water decreasing towards the eaves and the temperature of the snow melting water decreasing so that the snow is not melted, and the latter is not economical as it increases the construction cost and electricity bill. However, the current situation is that it is not widely used.

Recently, instead of these, natural snow-melting roofs have been developed and started to become popular, which use indoor warm air (exhaust heat from daily life) to heat the attic and melt the snow. It is not effective at all because it cannot cope with large amounts of snow during heavy snowfall.

[Problem that the invention attempts to solve]

The present invention solves this problem by forming the roof surface into a wavy flowing water roof surface, causing snow melting water such as groundwater, warm water, and stored water to flow down from the ridge toward the eaves in a wavy manner, and creating a wavy flowing water surface. The technical challenge is to provide an innovative running water type roof snow removal device that forcibly melts snowfall and snow accumulation.

[Means for solving problems]

A roof surface 1 having a slope is formed into a wavy running water roof surface in which concave strips 2 and convex strips 3 are alternately arranged laterally, and snow-melting water is sprinkled in the length direction of the ridge 4 of this roof. A water sprinkling device 5 is installed, and a drainage gutter 7 is provided in the lengthwise direction below the eaves 6, and the snow melting water is sprinkled from the water sprinkling device 5 and the wavy water flows down onto the roof surface in a broken pattern to melt the snow from the roof. In roof snow removal equipment, the ridge 4
One or more auxiliary sprinkler pipes 8 are provided above the roof surface 1 between the eaves and the eaves 6 in parallel with the sprinkler device 5.

[Effect]

Ground water, hot water,
When snow melting water such as stored water is sent, the snow melting water is sprinkled from the water sprinkler 5, and this snow melting water becomes wavy flowing water on the entire roof surface 1, that is, the uneven wavy running water roof surface, and flows from the ridge to the eaves side. Since it used to flow down in waves, it melts snowfall and accumulated snow on the surface of the water.

Melted snow water is collected in drainage gutter 7 and drained into drainage pipe 10.
is discharged to the outside through the

In this case, snow melting water is also sprinkled from the auxiliary sprinkler pipe 8 provided between the ridge section 4 and the eaves section 6, so that the wavy flowing water increases.

〔Example〕

The drawing shows a gable roof, and the sprinkler device 5 shows a case in which sprinkler holes 11 are bored at regular intervals in a sprinkler pipe 20. A water pipe 9 is connected to the sprinkler pipe 20, and a water pipe 9 is connected to the water pipe 20. A water pump 12 is provided, and the other end is connected to a water collection tank 13 on the ground.

This diagram shows a case where a heating device 14 such as a boiler, water supply pipe, water heater, etc. is installed outside (or inside) the water collection tank 13 to heat the snow melting water. It's a tube.

The wavy flowing roof surface of the drawing is made by constructing a rectangular plate 16 with raised parts 15 on the four sides as shown in Fig. 3, and a number of panel members 18 having convex shapes 3 protruding at regular intervals, depending on the roof area. The panel material 18 is prepared and placed on the roof (the roof of an existing building), and the front, rear, left and right raised parts 15 are assembled (crimped) to form the structure.

This panel material 18 is made of galvanized iron material, colored iron plate material,
Stainless steel materials, FRP materials, etc. are good.

The tip of the drain pipe 10 is connected to a water collection tank 13 to collect snowmelt water, that is, wastewater, into the water collection tank, and this wastewater is pumped up and sent to the sprinkler device 5 through the water supply pipe 9, where it is recycled again as snow melting water. The figure shows the case where

One auxiliary sprinkler pipe 8 is provided in the middle,
It is preferable to provide several pipes according to the width of the roof, and the auxiliary water sprinkling pipe 8 is provided with water sprinkling holes 22 at regular intervals so as to spray water toward the ridge 4 side.

The auxiliary water pipe 8 and the water pipe 9 are connected by a branch water pipe 19.

In the figure, 23 is a caulking part, 24 is an overflow pipe, and 17 is a valve.

[Effect of idea]

Since the present invention is configured as described above, the water sprinkler 5
Snow melting water flows down the roof surface as wavy water, so this wavy water motion generates slight heat due to friction between water molecules, which does not freeze the fluid, but instead lowers the temperature of the water. This wavy flowing water surface gradually melts snowfall and accumulated snow, making it possible to remove snow reliably.

In this case, more effective snow removal can be expected by increasing the amount of snow melting water flowing down depending on the outside temperature, amount of snowfall, amount of snow, roof area, etc., or heating the snow melting water to raise the water temperature. If the roof width is large and the distance between the ridge 4 and the eaves 6 is long, the amount of water sprinkled by the sprinkler 5 alone will not be enough, and the snow will melt steadily from above, so as it goes downwards. This lowers the temperature of the wavy water, making it more difficult to melt, and especially when the outside temperature is low or there is a lot of snowfall, snow may remain unmelted from the middle of the roof to the eaves.

In this regard, the present invention provides an auxiliary watering pipe 8 between the ridge part 4 and the eaves part 6, so if the snow is difficult to melt, the auxiliary watering pipe 8 sprinkles (adds water) water to melt the snow.
By causing a large amount of snow-melting water to flow down onto the roof surface 1, the amount of wavy flowing water is increased, and both the snow in the middle part of the roof and the snow at the eaves part 6 can be melted uniformly and completely melted.

In this way, the present invention provides an auxiliary sprinkler pipe 8 during snowfall.
It is possible to efficiently melt snow by sprinkling water from the ground and flowing a large amount of snow melting water, and since it is a method of melting snow using the frictional slight heat generated by the undulating water movement, the ridge side is also Since the water temperature is uniform even on the eaves side, the entire roof can be cleared of snow evenly, and in terms of fuel efficiency, there is no need to heat the snow melting water with a heating device unless the outside temperature drops below 0°, so it is better than conventional oil or gas. It is more economical than other types of roof snow removal equipment that use energy such as electricity.

Furthermore, this snow-melting roof also uses panel material 18 on the roof surface 1, and by combining these to form a double-layered roof, even if water leaks, it will only fall onto the roof of the existing building. It can also be used as a running water type roof snow removal device that can be used with peace of mind since there is no fear of water leaking inside the building.
