Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to the field of snow clearing devices.

[Prior art] As a conventional snow removing device, a blow-off pipe with a number of blow-off ports formed on the side surface is placed on the roof in Japanese Patent Application Laid-open No. 1983.
-Publication No. 33658 was published.

[Problems to be solved by the present invention] Conventional snow removal device (Japanese Patent Application Laid-Open No. 57-33658)
In this case, the outlet formed in the outlet pipe was formed directly on the outlet pipe. Furthermore, the blow-off pipe of the above-mentioned device was not equipped with anything to fix the blow-off pipe.

However, in the snow removal device of the present invention, the discharge port is provided in a projecting state at right angles to the axial direction of the duct, and the air sent by the air blower is directed in the length direction of the duct. Air is forcibly blown from the roof comb in the direction of the roof's nose, blowing away falling snow particles with extremely low resistance and changing the flow of snow in the direction of the roof's nose, eliminating or significantly reducing snow accumulation. At the same time, the air discharged from the roof gussets forces air into the middle of the snow that has accumulated on the tip of the roof, melting the snow, significantly reducing the amount of snow, and reducing the cost of removing snow. Furthermore, the load on the roof is reduced by significantly reducing the amount of snow.

[Means for Solving the Problems] The present invention provides a hollow duct in which a plurality of discharge ports are formed on both left and right symmetrical side surfaces, and a blower is connected to both or either of the front and rear side surfaces. In the snow removing device, which connects the air blower through a hose and drives the air blower to blow air into the duct at an appropriate speed, the air blower is installed at predetermined intervals on both left and right sides of the duct, and in the axial direction of the duct. A cylindrical discharge port, such as a short circular one, is provided at a right angle in communication with both side surfaces, and a support part shaped so that it can be straddled over the roof comb is attached to the bottom of the duct. This is a unique snow removal device.

[Embodiment] A is a hollow duct which is attached to a roof 1 in a straddling state without being blown away by wind and rain, and has the following configuration. That is, a plurality of discharge ports 5 are formed at predetermined intervals on both left and right side surfaces 4, 4' of the hollow rectangular duct a. Further, the outlet portion 5 is generally circular and is formed on both side surfaces 4, 4', but is not limited thereto. As a second embodiment, the above-mentioned left and right side surfaces 4,
The outlet portion 5 may be formed by forming comparatively short circular cylinders at predetermined intervals with respect to the outlet portion 4′ and attaching them at right angles to both side portions 4, 4′. Further, in addition to the first and second embodiments described above, the discharge port 5 may have a protruding shape and be inclined slightly parallel to the surface of the roof 1. Further, the outlet portions 5 formed on both side surfaces 4, 4' of the duct a may be integrally molded, or may be formed separately and fitted together. Further, when the duct a is of a unit type, a joining member b having an open end and a hollow shape is provided separately in order to join the duct a. Therefore, the duct a is made to correspond to the shape of the roof 1,
To place and fix the ducts on the comb 2, each duct a is joined via the above-mentioned joining member b. At that time roof 1
The joining member b may be adjusted by cutting it depending on the shape of the joining member b. From an aesthetic point of view, both the duct a and the connecting member b may be colored to match the color of the tiles of the roof 1, the boltless folding plate made of metal plate, or the like. Next, when the duct a and the connecting member b are placed on the sill 2 of the roof 1, the bottom part 3 of both bodies is
The comb 2 may be formed into an appropriate shape to match the shape of the comb 2. Reference numeral 6 denotes a front side portion constituting the duct a, and one end portion of a hose 7 is attached to the side portion 6, and the other end portion of the hose 7 is attached to the blower device 8, respectively. Reference numeral 9 denotes a rear side surface portion opposite to the front side surface portion 6 constituting the duct a, and one end portion of the hose 7 is connected to the side surface portion 9 as well as the front side portion 6, and the other end is connected to the side surface portion 9 as well. It may also be connected to the blower device 8. 10
is the bottom 3 of duct a to fix duct a.
It is a support part that can be attached to a plurality of parts such as the roof 1, etc., and is normally attached to the roof 1 in a straddling state via these support parts 10. As a result, even if the duct a etc. is exposed to wind and rain, it will not be blown away. Further, when the duct a is left as it is without being removed even during the winter season, the entire duct a or only the outlet portion 5 is shielded to prevent wild birds from building nests. Then, when winter arrives, the shielding will be lifted.
11 is the falling snow, 12 is a symbol representing the trajectory of the snow 11, and 13 is the tip of the nose.

Note that in the present invention, a snowfall sensor (not shown in the drawings) may be installed to automatically operate the blower device 8.

In addition, the air blower 8 can be installed without using the hose 7 mentioned above.
It is also possible to connect directly to the side parts 6, 9 of the duct a.

[Function] In the present invention, the exhaust port 5 constituting the duct a is kept open so that air can be blown, and when snow starts to fall, the blowing device 8 is immediately activated via a snowfall sensor. Alternatively, the blower device 8 is operated manually. As a result, the air whose amount of air has been adjusted is sent into the duct a through the hose 7, and the wind force is greatest near the outlet 5 from the numerous outlet portions 5, and the wind force is greatest near the tip of the nose 13 of the roof 1. The wind power gradually decreases as the direction increases and is continuously discharged. As a result, the falling snow 11 is moved in the direction of the tip 13 by the force of the blowing air, so that the amount of snow accumulated from the ridge 2 of the roof 1 to the tip 13 is small.

Furthermore, according to the present invention, when the hose 7 is connected to the front and rear side surfaces 6 and 9 of the duct a, the amount of air discharged from the outlet section 5 is larger than that in one case, and the falling snow 11 is moved as far away as possible. It can make it snow. As described above, by blowing a large amount of air from the discharge port 5 of the duct a, the snow is moved in the direction of the nose tip 13 of the roof 1 while being drawn into the blowing air, and the snow is moved to the nose tip 13 located below the roof 1. Only a small amount of snow can be seen in 13 areas.

As described above, during the day or night when it starts to snow or when snowfall is expected, the roof 1 is operated by operating the blower device 8 via the snowfall sensor.
It is possible to prevent snow from accumulating on top, and when the device of the present invention is left as is after the season, the entire device can be covered with a cover, or it can be disassembled and removed. can.

[Effects] The present invention has short cylindrical discharge ports protruding from the duct at predetermined intervals on both the left and right side surfaces of the duct, perpendicular to the axial direction of the duct, and in communication with both side surfaces. Furthermore, the structure is such that a support part that can be straddled over the roof beam is attached, the duct consisting of the above structure is installed in a state that it is straddled over the roof beam, and the duct and the blower are connected via a hose. Then, the adjusted amount of air is sent into the duct, and the sent air is forcibly discharged from the outlet, and the concentrated wind blows the falling snow with less resistance. By changing the falling direction from vertical to rotating, the snow is blown away towards the tip of the roof, preventing snow from accumulating between the roof trusses and the lower part, and therefore blowing off snow from the early stages of snowfall. The cost of rotating the fan is sufficient for this purpose, and therefore there is almost no snow removal work, which has the advantage of significantly reducing snow removal costs.
