Description

[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to an anti-fog net installed mainly on a roadside such as an expressway or a general road.
[0002]
[Prior art]
Japan's road network extends north and south, including highways, but this road network has various problems specific to each region, one of which is the region where fog frequently occurs. Thick fog often looks like smoke after the rain, etc., when water vapor condenses in the gas layer in contact with the wet ground, and floats in the air as innumerable small water droplets. In particular, when fog is generated on an expressway, the automobile is forced into speed regulation or stoppage, which causes a great deal of damage to both the road operator and the driver.
[0003]
On a highway, economic and social benefits are enormous if cars can always be driven without being affected by dense fog. For this reason, various measures have been taken to control fog. The most realistic countermeasure against fog is to set up a fog-proof net in the shape of a tunnel on the side of the road or on the side of the road and above the road.
[0004]
In a conventional fog-proof net, water vapor (mist) floating in the air is adhered to the net by a net having a fine mesh, and water is discharged when the water vapor condenses into water. Such anti-fog measures have already been implemented by the Highway Public Corporation and the Oita Administration Office, but this method makes the mesh finer to increase the net surface area. Therefore, (1) the influence of the wind pressure is great. (2) It has problems such as being easily damaged by wind pressure.
[0005]
Other prior arts in this field include Japanese Utility Model Laid-Open No. 64-32747 and Japanese Patent Application Laid-Open No. 2001-46836. In the former method, mist particles charged by corona discharge in a mist liquefaction and elimination electrostatic net are attached to a conductive net to liquefy and erase. The latter is for attaching and removing airborne substances such as fog passing through the suction fence ventilation section. All of these require the mesh to be small in order to improve the adhesion performance of suspended matter such as fog to the net or fence, and in this regard, have the same problem as the already-implemented anti-fog net. .
[0006]
[Problems to be solved by the invention]
In the conventional fog prevention net, the surface area of the net is increased by making the mesh fine, fog is attached to a wire forming the mesh, and the water is drained. However, by making the mesh finer, wind resistance increases, and a strong one is required. In addition, it may be damaged by a strong wind such as a typhoon, and maintenance costs are incurred. The conventional anti-fog net increases the surface area of the net by making the mesh finer, adheres fog, and drains water.
[0007]
The present invention has been proposed in order to solve the above-mentioned problems, and it is possible to reduce the wind resistance by enlarging the mesh so as not to be affected by the wind pressure, and still take a large net surface area. It is an object of the present invention to provide an anti-fog net having high fog adhesion efficiency.

[0026]
The anti-fog net of the present invention may have a large number of single thick wires (here, a thick wire is used in a relative sense that it is thicker than a thin short wire described later) in addition to the above-described configuration. It can also be constructed by bonding thin short wires of a book by bonding, or, when the thick wire is plastic or the like, cutting the plastic wire to form a short thin bar-shaped wire ( In addition, illustration is omitted.)
[0027]
The anti-fog net of the present invention is installed and used, for example, on the side of a highway as shown in FIG.

In FIG. 4, a required section (for example, an installation section over 9 km on the Oita Expressway, etc.) is provided along both sides of a road surface (vehicle traffic lane) 9 on which the vehicle 8 runs, and a fog prevention net 5 (5a) is installed. Is done. Of course, the anti-fog net 5 (5a) is configured to be incorporated in a frame of a metal frame 10 having weather resistance, for example, made of stainless steel or aluminum, and is erected on the side of a road. .
[0029]
Therefore, when fog is generated in the road section where the anti-fog net 5 (5a) is stretched, the fog which is going to flow toward the road surface 9 from both outer sides of the road is applied to the fog-proof net 5 (5a). ) Is captured by being attached to the short line (whisker) 4, and is prevented from flowing on the road surface 9, so that the vehicle 8 can secure a sufficient field of view and can run safely. Of course, since the fog also falls from above, when the fog prevention net 5 (5a) is not sufficient on both sides of the road, a fog prevention effect can be further increased by installing the fog prevention net 5 (5a) in a tunnel shape so as to cover the upper side of the road. Actually, since the fog flowing into the road from the lateral direction is not small, the fog prevention effect can be sufficiently expected even with the fog prevention net 5 (5a) only on the both sides of the road.
[0030]
It should be noted that it is within the technical scope of the present invention to carry out the present invention by appropriately designing and modifying the illustrated configuration.

【The invention's effect】
In the anti-fog net according to the present invention, the short wire fixed to the thick wire by any means, or the short wire fixed to a plurality of bones constituting the thick wire is fluttered in the wind. Even if it is located on the net of the net, it does not provide resistance to the wind flowing through the net, and the short line of the whisker greatly contributes to the increase of the effective surface area for fog deposition. Therefore, the effect of wind pressure can be reduced by enlarging the mesh of the net knitted by the bone line, thereby eliminating the possibility that the anti-fog net will overturn or break, improving durability and reducing maintenance costs. Help me. In addition, despite the large mesh, the mist floating in the atmosphere can be efficiently attached by the short line having a large whisker-like surface area located in the space portion of the mesh, and thus a simple configuration. In addition, it is possible to realize an efficient and anti-fog net. In another application of the net according to the present invention, the invention can also be applied to a blind fence.
