Abstract

(57) [Summary] (Modified) [Problem] To provide an inexpensive and effective snow blowing fence. A snow-proof fence is provided by mounting downwardly curved snow-proof plates (1) on a main pillar (2) at a fixed angle and at a constant interval so as to efficiently turn a horizontally blown wind in a downward oblique direction.

Description

[Detailed description of the device]

[0001]

[Technical field to which the device belongs]

  Regarding snow fences installed on the shoulders of roads.

[0002]

[Prior art]

  Of the snow fences used in snowy areas, roads are used to prevent snow from accumulating on the road surface. A snow blower fence was devised and used to blow off the snow by blowing wind on the road surface. Is used. A simple idea is to install a snow fence on the windward side of the road, It is good to set the snow plate diagonally to change the direction of the blowing wind downward. Yes.

[0003]   A corrugated sheet is usually used as a snow plate to give it strength, but There is a certain effect, but ideally, the one with a blade cross section is less likely to cause turbulence It is said to be good.

[0004]   However, a snow plate with a blade cross section is structurally complicated, manufacturing cost is high, and weight is heavy. However, there was a drawback in that it had to be increased.

[0005]

[Problems to be solved by the device]

  Blow-off that does not lead to cost increase while improving the effect of blowing snow to some extent Provide a snow fence.

[0006]

[Means for Solving the Problems]

  The present invention has been made in view of the above problems, and the wind blown horizontally is slanted downward. Fixed snow-protection plate made of downwardly curved plate to efficiently change direction Set vertically in a line.

[0007]

[Action]   According to the above-mentioned invention, the downwardly curved snow-preventing plate blows more horizontally. Compared to flat plates, snow can be directed more efficiently downward, so snow plates You can reduce the number of. In addition, depending on the shape, snow protection with a blade cross-sectional shape Since it has the same ability as a board, it also reduces weight and cost. Can be achieved.

[0008]

【Example】

  An embodiment of the snow fence of the present invention will be described with reference to the drawings. Fig. 1 shows the concept of the snow fence. In the side view shown, four snow-prevention plates 1 each having a width of about 60 cm and a length of about 4 m are arranged in a row on the main pillar 2. Each is fixed at a certain angle. If necessary, change the angle of the snow plate You can also The total height is about 3.5 m.

[0009]   As for the shape of the snow plate viewed from the side, the side 3 where the wind hits is generally horizontal, Then, it is gently bent downward, and the end edge 4 has an angle of about 45 degrees with respect to the horizontal direction. It has a degree.

[0010]   This snow fence is installed on the road shoulder. In this case, the road is located on the right side of this snow fence. Then, wind and snow that blows from the left side is bent downward by the snow protection plate and strongly blows against the road surface. Blow off the snow on the road surface.

[0011]   An example of the snow plate of the present invention is shown in FIG. This snow plate is about half of the total width Minute 5 is arcuate, and about 1/4 of the following part 6 extends on the tangent of the arc. And the remaining one-fourth straight line portion 7 is bent upward at about 8 degrees by about 10 degrees. .

[0012]   FIG. 3 is a side view showing the concept of another embodiment of the snow fence. The slope of the snow plate is high It becomes larger as it goes to, and it is more effective for wind and snow blowing horizontally from the left side. As a result, it is possible to converge on the road surface.

[0013]   Make the total opening ratio about 30% like the hole with a diameter of several cm on the top snow plate. It may be an open perforated plate. This is due to the inclusion of wind and snow on the back side of the top snow plate. It has the effect of preventing the occurrence of turbulent flow.

[0014]

[Effect of device]

  As described above, according to the present invention, a plate curved downward is used as a snow protection plate. Since it is used, it is possible to improve the blowing effect with a smaller number of snow protection plates than with a flat plate. A snow fence can be provided at a low cost.

[Brief description of drawings]

FIG. 1 is a side view showing the concept of the snow fence of the present invention.

FIG. 2 is a side view showing an example of a snow protection plate.

FIG. 3 is a side view of the snow fence that is larger as the inclination angle of the snow plate is higher.

Claims (4)

[Scope of utility model registration request] 1. A blow-off snow fence comprising a plurality of snow-preventing plates each having a curved surface curved downward so as to concentrate the blowing direction of the wind downward at a fixed inclination angle. 2. The snow fence as claimed in claim 1, wherein an angle of inclination with the horizontal of the snow plate is larger as the snow plate is higher. 3. The snow fence according to claim 1 or 2, wherein the uppermost snow fence is a perforated plate. 4. About half of the total width of the snow protection plate is curved in an arc shape, about one-fourth of the following is on the tangent line of the arc, and the remaining one-quarter is curved. The snow fence according to claims 1, 2 and 3, wherein a snow plate is used which is bent about 10 degrees in a direction opposite to the direction.
