Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a wind shield device that blocks wind across a road surface such as a bridge.
[0002]
[Prior art]
On bridges installed in mountainous areas and along the bay, it is difficult to drive the vehicle due to crosswinds (the handle is easy to take), so as shown in FIG. By standing 112, the wind (cross wind) 100 blowing from the lateral direction (width direction) of the bridge girder 111 is blocked by the wind shielding wall 112, thereby preventing the maneuverability of the vehicle 1 traveling on the road surface 111 a of the bridge girder 111 from being deteriorated. ing.
[0003]
[Problems to be solved by the invention]
However, if the cross wind 100 is blocked using the wind blocking wall 112 as described above, the following problems occur.
(1) Since the vehicle 1 is erected so as not to be exposed to the crosswind 100, the scenery from the vehicle window is also blocked and the scenery cannot be enjoyed.
(2) Since the windbreak wall 112 must be installed to withstand the strong winds 100 such as typhoons and seasonal winds, the stability of the bridge girder 111 due to the reaction of the blocked winds 100 And the stability of the road surface 111a may be reduced.
[0004]
For this reason, the present invention provides a windshield device that can prevent a decrease in the maneuverability of a vehicle due to a crosswind without causing a landscape blockage from a vehicle window or a decrease in road surface stability. Aimed at that.
[0006]
[Means for Solving the Problems]
A windshield device according to the present invention for solving the above-mentioned problems is provided on the side of a road surface, and an air blowing means for blowing air upward, and a wind speed for measuring the speed of wind blown from the lateral direction of the road surface. And a control means for controlling the blowing speed of the air from the air blowing means based on a signal from the anemometer, and the control means has the air at high and low wind speeds. The air blowing from the blowing means is stopped .
[0008]
DETAILED DESCRIPTION OF THE INVENTION
An embodiment in the case where the wind shield device according to the present invention is applied to a bridge will be described with reference to FIG. FIG. 1 is a schematic configuration diagram of the apparatus.
[0009]
As shown in FIG. 1, slit nozzles 12 that are open toward the upper side of the road surface 11 a are respectively provided on both ends (both sides) of the road surface 11 a on the bridge girder 11 in the width direction. Inside the bridge beam 11, a blower fan 13 that is rotationally driven by the operation of the drive motor 14 and sends the air 101 to the slit nozzle 12 is provided. That is, when the drive motor 14 is operated to drive and rotate the blower fan 13, the air 101 can be blown out from the slit nozzle 12 toward the upper side of the road surface 11a. In this embodiment, the slit nozzle 12, the blower fan 13, the drive motor 14, and the like constitute air blowing means.
[0010]
As shown in FIG. 1, an anemometer 15 for measuring the speed of the wind (cross wind) 100 blowing from the lateral direction (width direction) with respect to the bridge girder 11 is provided on the outer side in the width direction of the bridge girder 11 of the slit nozzle 12. It has been. These anemometers 15 are each electrically connected to an input part of a control device 16 that is a control means, and the drive motor 14 is electrically connected to an output part of the control device 16, respectively. Reference numeral 16 denotes a rotational speed of the drive motor 14 based on a measurement signal from the anemometer 15 so that the speed of the air 101 blown out from the slit nozzle 12 becomes a preset wind speed ratio (measured wind speed / blown wind speed). It comes to control. In FIG. 1, 1 is a vehicle, 16a is an indicator, 16b is a personal computer, and 16c is a rotation controller.
[0011]
Next, a wind shielding method using such a wind shielding device will be described.
When the anemometer 15 measures the speed of the cross wind 100 and the speed of the cross wind 100 is within a predetermined range, the control device 16 is based on the wind speed measured by the anemometer 15 and the preset wind speed ratio. Then, the speed of the air 101 blown from the slit nozzle 12 is calculated, and the drive motor 14 is controlled to drive and rotate the blower fan 13 so that the air 101 is blown from the slit nozzle 12 at this speed.
[0012]
When the air 101 is blown out from the slit nozzle 12 toward the upper side of the road surface 11a of the bridge girder 11 in this way, the air 101 blows up the cross wind 100 upward, so that the cross wind 100 is on the road surface 11a of the bridge girder 11. Suppress crossing.
[0013]
Further, when the speed of the cross wind 100 is out of a predetermined range, that is, when the wind speed is high such as a typhoon or a seasonal wind, or when the wind speed is low so as not to interfere with the running of the vehicle 1, the measurement signal from the anemometer 15 is used. Then, the control device 16 stops the operation of the drive motor 14 and stops the driving rotation of the blower fan 13 so as to stop the blowing of the air 101 from the slit nozzle 12. That is, when there is no need to suppress the crossing of the crosswind 11 on the road surface 11a of the cross girder 100, the blowing of the air 101 is stopped.
[0014]
Accordingly, not only can the deterioration of the controllability of the vehicle 1 due to the crosswind 100 be prevented, but the scenery from the vehicle window of the vehicle 1 is not blocked, so that the passenger of the vehicle 1 can enjoy the scenery. .
[0015]
In addition, when a very strong cross wind 100 such as a typhoon or a seasonal wind blows, the blow out of the air 101 can be stopped and allowed to pass through without suppressing the progress of the cross wind 100. The reaction caused by the suppression of 100 is eliminated, the stability of the bridge girder 11 can be easily maintained, and the stability of the road surface 11a can also be easily maintained.
[0017]
【The invention's effect】
According to the wind shielding device of the present invention, by toward the side of the road surface with air blow means upward blowing air, so block the wind blowing from the side of the road, to suppress the cross on crosswind road In addition , it is possible not only to prevent the vehicle from being deteriorated by crosswind, but also to prevent the vehicle passengers from enjoying the scenery. Moreover, it is possible to suppress the crossing of the crosswind on the road surface with the minimum necessary air according to the wind speed of the crosswind, and it is possible to operate the air blowing means efficiently, as well as typhoons and seasonal winds. When such a very strong cross wind blows, the control means stops the air blowing from the air blowing means based on the measurement signal from the anemometer, so the cross wind is not obstructed and the road surface is easy. To pass through. For this reason, the reaction caused by the suppression of the cross wind can be easily eliminated, and the stability of the road surface can be easily maintained.
