Description

[Detailed Description of the Invention] A. Industrial Application Field The present invention is a blow-off snow fence for preventing snow accumulation and snowdrifts on roads (and railways) in snowy areas, ensuring passage of people and vehicles, and protecting traffic safety. It is related to. B. Conventional technology Conventionally, in snow-covered areas, snowfall and snowdrifts can form on roads (and railways) during the winter, making it impossible for vehicles and railcars to pass at all, or creating obstacles to their passage. be. In order to prevent this, snow prevention poles are installed along the road, which are made of horizontal plates with a predetermined gap between them.
There was a transparent snow fence in Japanese Utility Model Application Publication No. 58-153208, and a snow prevention fence in which the angle of the snow board could be changed in Japanese Utility Model Application Publication No. 59-61313. C. Problems to be Solved by the Invention In the above-mentioned snow fence made of horizontal plate-shaped bodies with a predetermined gap, the entire plate-shaped bodies are oriented in the same direction, and the wind is simply directed downward so that the road However, the plate-shaped body blocked the view and made it impossible to see through, making it inconvenient to not be able to see the scene on the other side of the snow fence. In addition, in the transparent snow shield disclosed in Japanese Utility Model Application Publication No. 58-153208, a transparent snow shield is used as the lower one of several snow shields. This transparent snow protection board has many large through holes. Therefore, it takes a lot of effort to manufacture it, and it is expensive, making it uneconomical.
Furthermore, the snow fence disclosed in Japanese Utility Model Application Publication No. 59-61313, which can change the angle of the snow prevention plates, has a plurality of snow prevention plates rotatably attached between two pillars, and the snow prevention plates are connected to each other. A device is provided for releasably fixing the connecting rod to the column at at least two pivot positions of the snow protection plate. Therefore, the structure is complex, and changing the angle of each snow protection plate each time requires maintenance and management, and also requires time and effort to manufacture. Furthermore, it is not economical as it may cause failures in rotating parts. There wasn't. The purpose of this invention is to solve the above-mentioned problems of conventional snow fences, eliminate snow accumulation on roads, and provide a blow-off snow fence that can be seen through. D. Means for Solving the Problems To achieve this object, the invention of the present application has the following configuration. That is, the invention according to claim 1 comprises a vertical blow-off section which is provided directly on the windward side of the road and connected vertically with a plurality of slit-shaped gaps, and the windward side of the vertical blow-off section is This is a blow-off snow fence characterized by the steel surface being formed to have a flat, bent or curved shape. In the present invention, snow does not accumulate on the road because the wind passes through the slit-shaped gap in the vertical blow-off section. The above-mentioned vertical blow-off section may be installed parallel to the road with a certain gap, or it may be installed at a certain angle with respect to the road with a certain gap. It may be installed as follows. The above-mentioned vertical upwelling section with a flat surface on the windward side may be smooth, or may have a through hole through which the wind can pass. It also includes cylindrical and columnar shapes. For refracted ones, the angle of refraction can be any angle, as long as they face upwind and are designed to guide the wind. Also, there may be some width in the bent part. The bent shape may be two-sided, cylindrical, or columnar, similar to the flat shape described above. The windward side of the vertical blow-up part has a curved shape (if there is one,
It may be semicircular, cylindrical as above, or columnar. Similar to the above-mentioned bent type, it also includes those with through holes. For thick flat, bent or curved objects, for example, cylindrical and columnar objects, the upper end should be placed on the windward side to prevent snow from adhering to or accumulating on the upper end. This also includes those that are inclined so that they have an angle. The material of the vertical blow-off section includes, for example, a material coated with fluororesin, ceramics, aluminum, stainless steel, colored steel plate,
A wide variety of materials are used, including wood and other materials that are difficult for snow to adhere to, as well as paint. Incidentally, the interval between the gaps of the slits in the vertical blow-off section is not necessarily constant;
It varies depending on the installation location, road width, etc. The invention of claim 2 provides a blow-up section provided directly on the windward side of the road, and a vertical blow-off blow-up section located above the blow-off section that is connected to the blow-off section with a vertical slit-shaped gap located directly above the blow-off section. The upper end surface of the blower section is formed with an inclined surface angled to guide the wind toward the windward side, and the windward side surface of the vertical blower section is flat so as to guide the wind. This is a snow protection tank characterized by being formed to have a bent shape or a curved shape. In the present invention, the angle of the slope of the blower part provided on the windward side of the road may be any angle that can guide the wind, but it is effective if it is 45 degrees or more. Also, it is installed along the road on the windward side of the road. Of course, it is fixed to the road. A vertical blow-off part is installed directly above the blow-off part, and its shape, size, material, etc. are the same as those of the invention of claim 1 above. E. In the blow-off snow protection pole according to the invention of claim 1, the blowing wind is narrowed by the slit-like gap of the vertical blow-off pole installed directly on the windward side of the road, and its speed is increased. The width of the vehicle is narrowed when it passes through or hits a vertical blow-up section, so it speeds up, passes through a slit-like gap, and blows over the road. Therefore, even if it is raining or snowing at this time, lightning will not accumulate on the road. On the windward side of a vertical blow-up section, where the upper end is sloped, the wind is blown upward. In the blow-off snow prevention oval of the invention of claim 2, when the blowing wind that blows downward reaches the blow-off section installed directly on the windward side of the road, it is blown up by the slope and increases its speed. , and the width is narrowed by the slit-like gap in the vertical blow-up section, so the vehicle passes through the road at even greater speed. Therefore, even if it snows at this time, it does not accumulate on the roads. In addition, the wind blowing above the blow-off section is narrowed in width by the vertical blow-off section and passes through the slit-shaped gap at an increased speed, passing through the road, so there is no accumulation on the road in the same way as above. do not have. F. EXAMPLE An example of the present invention will be explained with reference to the drawings. First Embodiment of the Invention of Claim 1 The first embodiment of the invention of Claim 1 will be described with reference to FIGS. 1 to 3. FIG. 1 is a partially enlarged perspective view of the invention. A flat vertical blow-off part 2 is installed directly on the windward shoulder IA of the road 1! It has been done. The flat plate-shaped vertical blowing part 2 has a slit-shaped gap S parallel to the road shoulder IA of the road 1.
are set up and arranged in series. The vertical blow-off section 2 is rectangular in shape and has stripes to prevent snow from adhering to it.The height is determined by the installation location and the condition of the road, i.e. width, topography, and other conditions. The same applies to the slit-shaped gap S. The flat vertical blow-off section 2 is made of materials coated with fluorine resin, ceramics, aluminum, stainless steel, colored steel plates, materials to which snow does not adhere such as wood, and materials with wide convergence such as tJl material. Since the blow-off snow prevention fence A of this embodiment is designed as shown in FIG. The vehicle also passes through the road 1 at once, or passes at increased speed through the slit-shaped opening S narrowed by the vertical blow-up section 2, and also passes through the road 1 at once. If it was raining at this time, road 1
There is no snow on the ground. To install the vertical blow-off blow-up section 2 at Road NIA,
It can be easily installed by burying it. In addition, depending on the wind direction and other conditions, the vertical blow-off section 2
In some cases, it is not installed parallel to the road WIA, but at an angle as shown in Figure 3. In this case as well, the effect is Pil-like. As mentioned above, in this embodiment, the flat vertical blow-off blow-up section 2 has a rectangular flat shape that is easy to scrape, and is installed by being buried in the road shoulder IA, so that the work can be carried out efficiently. It is inexpensive and economical. Furthermore, since the slit-shaped gaps S between each of the vertical blow-off blow-up sections 2 are vertical, the scene outside the road can be seen even when passing by a vehicle. Second embodiment of the invention of claim 1 A second embodiment of the invention of claim 1 will be explained with reference to FIGS. 4 to 6. In this embodiment, instead of the flat vertical blow-off part 2 in the first embodiment, a vertical blow-off part of another shape is installed. That is, in FIG. 4, vertical blow-off parts 20 in the form of flat plates are connected in parallel along and directly above the road shoulder IA so as to have a slit-like gap S between them. A slight portion from the upper end edge on the windward side of the flat plate-shaped vertical blow-off blow-up section 20 is an inclined surface a. Fifth
As shown in the figure, this is to minimize the ms of the upper end surface of the flat plate-shaped vertical blow-off section 20 to prevent snow from accumulating. The size, shape, material, and function or effect of the other flat plate-like vertical blow-off portions 20 are the same as those in the first embodiment. In addition, what is shown in (A) to (1) in FIG. 6 shows other shapes of vertical blow-off blow-off parts that are used instead of the flat plate-shaped vertical blow-off blow-off part 20 shown in FIG. It is something. That is, what is shown in FIG. 6(A) is a flat plate-shaped vertical blow-off blow-up tube 2 having through-holes 5 throughout, which are arranged in parallel and connected so as to have a slit-like gap S. Therefore, depending on the size of the through hole 5, the scene on the other side can also be seen. FIG. 6(B) shows a flat bent vertical blow-off part 3. In this case, the windward side is bent and split into two, so the wind speed seems to be faster. The angle of the bend can be arbitrary as long as it can guide the wind upwind. What is shown in FIG. 6(C) is a refracted vertical blow-off blow-up section 3 having a through hole 5 throughout, which is arranged in parallel so as to have a slit-like gap S. Therefore,
Wind also passes through the through hole 5. Also, the scene on the other side may be visible through the through hole 5. The angle of refraction is the same as in (B) above. Fig. 6(D) shows a flat bent cylinder-shaped vertical blow-off section 3''. In this case as well, it is installed horizontally or at an angle to the road shoulder IA. The angle of refraction is the same as in (C) above. FIG. 6(E) shows a bent columnar vertical blow-off section 30.
This is what is shown. There is a slope a slightly below the upper edge on the windward side. Therefore, snow does not accumulate on the upper edge. The angle of refraction is arbitrary as before. The rest is the same as (B), (C), and (D) above. Figure 6 (F) shows the curved vertical blow-off part 4 of the flat plate.
This is what is shown. Turn the curved surface toward the windward side. This consecutive pitch is also the same as the one above. This blow-up section 4, which has a curved windward side, also allows the wind 7 to flow more smoothly than when it is simply flat, so the speed is thought to be faster. The curved shape may be part of a circle, ellipse, or other curve. Figure 6 (G) shows the curved vertical blow-off section 4 of the flat plate.
This figure shows one with through holes 5 throughout. Air passes through the through hole 5 in the same manner as described above. Figure 6 (H) shows a curved cylindrical vertical blow-off part 4' of a flat plate. Any side can be on the windward side.
The cylinder shape may be circular, oval, or other shapes. Figure 6 (I) shows the curved columnar vertical blow-off section 4.
It shows 0. The upper edge on the windward side is slightly sloped. Therefore, snow does not accumulate at the top. The column shape may be circular, oval, or curved. As mentioned above, even if the windward side has a bent or curved shape, the wind passes through it at a faster speed and there is no snow buildup.
It is simple in shape, economical, and durable. First embodiment of the invention of claim 2 The first embodiment of the invention of claim 2 of the blow-off snow prevention oval A of the present invention
Examples are shown in Figures 7 and 8. An upwelling section 6 is installed along the shoulder IA of the road 1. The blower section 6 is inclined with respect to the windward side. The angle of inclination is free. However, it is effective if the angle is 45° or more. A wide range of materials are used, including fluororesin-coated materials, ceramics, aluminum, stainless steel, colored steel plates, materials to which snow does not adhere, such as wood, and paint. Directly above the blower part 6, a flat plate-shaped vertical blower blower part 2 is arranged in series so as to have a slit-like gap S. The flat plate-shaped vertical blow-off section 2 is parallel to the road shoulder lA, and the rest is the same as the embodiment of the invention according to claim 1. Among the blowing winds, the wind blowing downward is blown up by the blow-off section inclined surface 6A and crosses the road 1 through the mutual slit-like gaps S of the flat blow-off section 2. Therefore. Even if it snows, it does not accumulate on Road 1.
Incidentally, the wind 7 blowing upward passes through the mutual slit-shaped gaps S of the flat vertical blow-off portions 2 at an increased speed, crosses over the road 1, and passes through. The blow-off snow fence A of this embodiment has a simple structure and is economical. Since the slit-shaped gap S is not horizontal but vertical, the scene on the other side of the blow-off snow fence A can be seen from a moving vehicle. Second Embodiment of the Invention of Claim 2 A second embodiment of the invention of Claim 2 is shown in FIGS. 9 and 10. The present embodiment differs from the first embodiment in that the bent columnar vertical blow-off section 30 is located above the blow-off section 6.
The rest is the same as the first embodiment. B folded columnar blowing part 3
0, the windward side has an angular bent shape, and a slight portion of the windward side from the upper end is a slope a. When the blowing wind 7 hits the slope a, it rises upward. Therefore,
There's no snow here. Wind 7 blowing on the blower slope 6A
is a bent columnar vertical blow-off part 3.
0, passes through the slit-shaped gap S at higher speed, and passes over the road 1. Therefore, snow does not accumulate on road 1. Bent columnar vertical blow-off part 3 in this embodiment
0, a flat plate-like vertical blow-off part 20,
The ones shown in FIGS. 6(A) to (C) and (F) to (1) may also be used. These functions, effects, and others are the same as those of the second embodiment of the invention as claimed in claim 1. The embodiments of the invention of claim 1 and the invention of claim 2 are not limited to those described above, and it is of course possible to implement various other designs with changes within the scope of the claims. be. G.
