DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The first and second embodiments of the present invention will be described with reference to FIGS.

The constituent members similar to those of the first embodiment are the same as those of the second embodiment.
In the embodiments, the same reference numerals are given and the description thereof will be omitted unless necessary.

(First Embodiment) A first embodiment of the fog eliminating device according to the invention of claim 1 will be described with reference to FIG.

FIG. 1 is a perspective view of this embodiment.
1 is a suspension high-speed road, 2a and 2b are left and right side plates of the road 1, 3 is a mesh-like structure supported above the road 1 by the side plates 2a and 2b, and 4 is a mesh-like structure 3 A plurality of heating wires 5 supported in parallel from one electric wire 5 to the other electric wire 5 are electric wires arranged along the side plates 2a and 2b as base lines of the heating wire 4, one side of which is plus, The other side is negative. Reference numeral 6 denotes a control switch for energizing the heating wire 4 via the electric wire 5 when the fog F is generated, which is operated by an on / off command signal sent from a road control center (not shown) or the like according to the generation state of the fog F. . 7
Is an electric power supply line for supplying electric power to the heating wire 4 through the electric wire 5.

Next, the operation of the above configuration will be described.

When the fog F is generated because the control switch 6 is normally off, the control switch 6 is turned on by a control signal from the road control center.

Then, an electric current flows through the heating wire 4 via the electric wire 5, the heating wire 4 heats up and the fog F near the upper part of the road 1 disappears, so that an automobile or the like can freely pass at a normal speed.

Fog F is climatic (not by this device)
If it goes wrong, the control switch 6 is turned off again.

In this embodiment, the on / off of the control switch 6 is described as an example of remote operation, but it goes without saying that it may be turned on / off manually or by any other means.

(Second Embodiment) A second embodiment of the fog eliminating device according to the invention of claim 2 will be described with reference to FIG.

FIG. 2 is a perspective view of this embodiment.
8 is a light emitter which is supported by the side plate 2b of the left and right side plates 2a and 2b of the road 1, and which periodically emits light R toward the light receiver 9 which is supported by the other side plate 2a. The light receiver 10 receives the light R of the light and inputs a strong current (or a strong voltage) to the detection circuit 10 according to the strength of the light R, and 10 is a strong current (or a strong voltage) from the light receiver 9.
In response, the detection circuit sends an ON signal to the control switch 6 when it is determined to be a weak current (or a weak voltage) due to, for example, obstruction of fog.

It should be noted that the light receiver 9 and the detection circuit 10 may be made to be able to react to the intensity of ordinary white light, or the power spectrum reaction system is selected to be a spectrum that is sensitive to the passage of fog (the opposite of fog lamps). When the weakness exceeds the limit, it may be judged as fog and an ON signal may be output to the control switch 6, or, for example, smoke emission of an automobile, particularly smoke emission of a diesel vehicle It seems that it temporarily has a strong light-shielding effect, but the degree of light-shielding is abrupt and instantaneous, but the occurrence of fog, which is a natural phenomenon, is due to the fact that the concentration progresses in the diesel smoke emission range. Even if it is not, and is persistent, it may be determined that the shading due to fog is distinguished from the shading due to other events based on the sudden change in shading, its continuity, and other frequencies, and so on. There.

The other structure is the same as that of the first embodiment.

Next, the operation of the above configuration will be described.

When the fog F is generated, the light R from the light emitting device 8 is changed, and the light receiving device 9 which receives the change inputs the changed signal to the detection circuit 10. When the detection circuit 10 determines that the change is due to fog, it sends an ON signal to the control switch 6 to energize the electric wire 5 and the heating wire 4. As a result, the same effect as that of the first embodiment can be obtained.

In the case of the present embodiment, for example, the load of an abnormally tall automobile (it is practically impossible to judge it as fog by the above-mentioned device), smoke emission, etc. are misidentified as fog. Even if the heating wire 4 is energized, no trouble will occur.

As described above, according to the first and second embodiments,
Even if fog occurs on the road 1, it can be immediately extinguished by energizing the heating wire 4, so that automobiles can operate at speeds that do not change from normal, and therefore, there is no need to close the road and, of course, physical distribution is required. It has the advantage of not being hindered.

Further, since the fog is eliminated, the forward line-of-sight distance which is not changed from the usual one is secured, and there is an advantage that a rear-end collision due to the fog is eliminated.

Further, since the main weight part of the apparatus is only the mesh-shaped structure 3, the heating wire 4, the electric wire 5, etc., it is easy to carry, has good transportability and handleability, is easy to construct, and is easy to move. is there.

Further, since the members are extremely simple and inexpensive to obtain, there is an advantage that the device can be obtained at low cost.

Also, since the standards for highways and the like are almost constant, and the location of frequent fog is accurately grasped from statistical data, etc., the equipment is compatible and wasteful for installation. There is an advantage that it does not occur.

Further, since the support for the heating wire 4 and the like is the mesh-like structure 3, it has a high flow-through property and does not produce flutter even along the flow, so it is lightweight but strong against wind. It has the advantage of being strong.

Further, the mesh structure 3 has an advantage that it has a high porosity and is excellent in daylighting property.

In addition, the second embodiment has an advantage that the above-mentioned advantages can be automatically created without bothering humans.

[0037]

The present invention has the following effects because it is configured as described above.

That is, since the fog in the vicinity of the road can be obscured by the fog eliminator, the operation of automobiles and the like is never stopped due to the fog, which impedes physical distribution. As a result, the efficiency of the industry will be improved.

Further, there is no rear-end collision due to fog.

A device exhibiting the above-mentioned effects can be obtained at low cost.

In particular, according to the second aspect of the present invention, it is possible to change a road in which fog is frequently generated to a road in which fog is not generated at all, and which is completely unmanned.
