Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a roof snow removal device.

[Prior art] Conventionally, as this type of roof snow treatment apparatus, there is a method in which snow on a roof is sprayed from a water sprinkling pipe to eliminate snow, a method in which the heat is melted by electric heat, and a method in which hot water of groundwater is passed through a pipe to melt. It has been known.

[Problems to be Solved by the Invention] However, in the case of these conventional structures, the electric heating method and the hot water method require a large amount of heat, so that operating costs such as electricity costs and boiler fuel costs are increased, and economic efficiency is low. Also, the method using groundwater has a disadvantage that the groundwater may be depleted or land subsidence may occur.

[Means for Solving the Problems] An object of the present invention is to solve these inconveniences. The gist of the present invention is to provide a pump for pumping water from a water source such as a river or a pond, and a flowing water pipe provided on a roof. Wherein the snow cover on the roof is eliminated by running water from a running water pipe, wherein the roof is provided with a snow-melting water falling from the eaves and a water-transmitting sheet capable of transmitting and guiding the water downward, and A roof snow-removal device is characterized in that a return path including a walking path is formed between the eaves of the roof and the water source.

[Operation] Pumped water from a water source such as a river or pond is pumped, and water is flown from a water pipe provided on the roof. Snow on the roof is eliminated by flowing water from the water pipe, and snowmelt flows down the roof. And the water falls from the eaves, and the snowmelt water and the water are guided downward along the water transmission sheet, and the water dropped at the lower part of the eaves of the roof is returned to the water source through a return path including a walkway. I do.

[Embodiment] Figs. 1 to 5 show an embodiment of the present invention, wherein 1 is a building, 2 is a roof, in this case, a gable roof shape has a two-story structure, and a running water pipe 3 is attached to a ridge portion. A large number of water holes 4 are formed in the water pipe 3 along the longitudinal direction. The water flow direction of the water holes 4 is set to be substantially opposite to the roof surface, and the hole is made as large as possible. Is considered.

Reference numeral 5 denotes a water source, which is a reservoir in this case. A pump 6 is installed on the ground, an intake pipe 7 of the pump 6 is inserted into the water source 5, and a water supply pipe 8 of the pump 6 is connected to the water pipe 3. The connection pipe 9 is used for piping.

Numeral 10 denotes a water transfer sheet, which is made of a flexible resin, has one side attached to the eaves of the upper roof 2 and hangs down to the lower part of the eaves of the lower roof 2, and is folded back to form the upper roof 2. The other side is attached to the eaves portion, and the weight 20 is attached to the folded portion.

Numeral 11 denotes a return channel formed between the eaves lower part 12 and the water source 5, in this case, a dog running part 13 is formed around the building 1 by concrete, and a low protruding part 14 is formed around the same. It is formed so as to include a connection part of an entrance passage as a passage 15 and a passage connected to a road, and is formed so that water that has fallen on the eaves lower part 12 flows to the water source 5.

In this case, a partition weir portion 16 is formed at an appropriate position of the return path 11,
It flows over the partition weir 16 while overflowing sequentially.

Since this embodiment has the above structure, the pump 6 pumps water from the water source 5 such as a river or a pond, and the roof 2
The water is sent to the water pipe 3 provided above, and flows from the water hole 4 of the water pipe 3, and the snow S on the roof 2 is eliminated by the water.

And the snowmelt water flowing down the roof 2 and the water from the water pipe 3 flow down by the roof gradient of the upper roof 2,
This water flows along the water transfer sheet 10 and the lower eaves 12 of the lower roof 2
fall into.

The water that has fallen into the eaves lower part 12 returns to the water source 5 through the return path 11 including the walking path 15.

Therefore, snow can be eliminated by water circulating through the water source 5, the pump 6, the roof 2, and the return channel 11, and there is no danger of depletion of groundwater or land subsidence, and water falling from the eaves of the upper roof 2 Can drop on the eaves portion 12 of the lower roof 2 along the water transmission sheet 10 so that the noise generated at the time of collision with the lower roof 2 can be reduced. The water flow direction of the water flow hole 4 is set substantially in the direction opposite to the roof surface, and the hole is made as large as possible, so that the water flow distance can be shortened, the water flow pressure can be reduced, and the noise due to water can be reduced. Lower eaves 12
The dog running section 13 is formed in the area, so that snow easily accumulates on the dog running section 13, and the sound of water colliding with the concrete surface of the return channel 11 in the lower eaves 12 due to the snow accumulated on the dog running section 13 This will provide a soundproofing effect, and the water that has fallen into the lower part 12 of the eaves will return to the water source 5 through the return path 11 including the walk path 15, and this water will also reduce snow in the walk path 15. In this case, since the return path 11 is provided with the partitioning weir 16 at an appropriate position, water flows over the partitioning weir 16 while sequentially overflowing the partitioning weir 16, thereby improving the snow removing effect. .

In addition, roof structure, pump 6, water transfer sheet 10, return path 11,
The structure and shape of the walking passage 15 are not limited to those in the above-described embodiment, and are appropriately designed.

In the above embodiment, the water source 5 is a reservoir, but water from a river or a lake may be used.

[Effects of the Invention] As described above, the present invention can eliminate snow from the water source through the roof and the water circulating through the return channel, and does not cause depletion of groundwater or land subsidence. The falling water is guided down the water transmission sheet and falls while falling, so that the noise generated at the time of collision can be significantly reduced, and the water falling at the lower part of the eaves passes through a return path including a walking passage to a water source. Since the water flows back, the water can eliminate the snow elimination in the walking passage.

As described above, the intended purpose can be sufficiently achieved.
