Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention mainly relates to a soundproof wall installed along a road or the like.

[0002]

2. Description of the Related Art Conventionally, a soundproof wall installed on a road has only a purpose of preventing noise when a plurality of soundproof panels are stacked between columns arranged at a predetermined interval. In addition to the soundproof wall, a light emitting display device was installed on the roadside of the soundproof wall for displaying visual guidance, guidance, warnings, etc. for the purpose of traffic safety.

[0003]

However, in the related art, since the light emitting display device for traffic safety is installed separately from the noise barrier for noise prevention, the installation work,
There is a problem that it takes time and labor for power supply work and the construction cost is high. Further, even if a solar cell is used as a power source for the light emitting display device, the light receiving area of the solar cell cannot be increased so much that only a small capacity light emitting display device can be installed due to space limitations, and the solar cell is shaded by a soundproof wall. There was a problem that it was difficult to use because the amount of power generation decreased due to the light reception failure.

An object of the present invention is to provide a soundproof wall that solves the above-mentioned conventional problems.

[0005]

In order to solve the above problems, the present invention incorporates a solar cell and a display unit that emits light into a soundproof panel so that a light emitting display device for traffic safety can be installed at the same time as the construction of a soundproof wall. It was done like this. That is, the soundproof wall of the present invention is a soundproof wall in which a plurality of soundproof panels are stacked and provided between columns arranged at a predetermined interval, and among the plurality of soundproof panels, a solar cell is It includes a built-in soundproof panel for a power supply, and a soundproof panel for display in which a display unit including a light emitting display section, a storage battery and a control section is built in, and the solar cell and the display unit are connected to each other.

[0006]

When the soundproof panel is placed between the columns to construct the soundproof wall, the solar cell and the display unit are simultaneously arranged at predetermined positions. The solar cell can be arranged so as not to be affected by light reception due to the shadow of the soundproof wall, the power generated by the solar cell is stored in the storage battery of the display unit, and the light emission display section is controlled to emit light by the control section.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below with reference to the drawings. In the drawings, 1 is a column, which is generally made of a steel material such as H-shaped steel and is provided in a plurality of rows along a road at predetermined intervals. The pillar 1 may be a straight upright pillar, but if the upper end is formed as a bent pillar which is bent and inclined toward the road side as shown in FIGS. When the solar cell 4 is attached, the light receiving surface of the solar cell 4 faces upward, which is preferable.

Reference numeral 2 is a soundproof panel, which is generally a quadrangular panel, and a plurality of stages are stacked between the columns 1 and are provided. The soundproof panel 2 may be made of an appropriate material such as a general-purpose sound-insulating, sound-absorbing, and both sound-absorbing and sound-insulating material. What is filled with a sound absorbing material may be used.

Reference numeral 3 denotes a soundproof panel for a power source, and a panel-shaped solar cell 4 is incorporated in one surface of the soundproof panel 2. In this soundproof panel 3 for a power source, a solar cell 4 is generally installed on the back side opposite to the road side, and the solar cell 4 is placed between the upper ends of the pillars 1 as shown in FIGS. It is designed to face. Further, the soundproof panel 3 for the power source is not limited to the above, and may be passed between the pillars 1 at a position where the received power of the solar cell 4 is not hindered.

Reference numeral 5 denotes a soundproof panel for display, in which a display unit 6 is installed on the front surface of the soundproof panel 2 facing the road side, and is generally passed between the columns 1 at a height position which is easily seen by a vehicle driver. ing. The soundproof panel 5 for display may be provided so as to correspond to the soundproof panel 3 for power supply in a one-to-one manner, or when the electromotive force of the solar cell 4 is sufficient. Multiple may be provided for.

The display unit 6 has, for example, a panel shape including a light emitting display section 7, a storage battery 8 and a control section 9. In the case of FIG. 1, the light emitting display unit 7 is indicated by an arrow light emitting display, but in addition, other line-of-sight guidance lights, guides and information display boards
It may be a display that emits light as appropriate such as a warning display,
The structure or the like may be the same as the conventional structure such as using a light emitting diode or the like.

Reference numeral 10 denotes a cable for connecting the solar cell 4 of the power source soundproof panel 3 and the display unit 6 of the display soundproof panel 5. The cable 10 is generally wired along the support column 1, and when a plurality of display soundproof panels 5 are provided, they are also wired between the display units 6 of the panel 5.

In the soundproof wall of the present invention, however, the electric power generated by the solar battery 4 of the soundproof panel 3 for power supply is stored in the storage battery 8 of the display unit 6 of the soundproof panel 5 for display, and the stored electric power causes a light emission display. The light emission of the unit 7 is controlled via the control unit 9.

[0014]

As described in detail above, the soundproof wall of the present invention comprises a plurality of soundproof panels forming a soundproof wall, a soundproof panel for a power source in which a solar cell is incorporated, a light emitting display section, a storage battery, and a control section. Since it includes a soundproof panel for display that incorporates a display unit equipped with, a light emitting display device for traffic safety can be installed at the same time as the construction of the soundproof wall. Moreover, it is not necessary to separately construct a power source for the light emitting display, and the construction cost can be reduced.

Further, since the solar cell is incorporated in the soundproof panel, the light receiving area of the solar cell is not limited to a small value as in the conventional case, and the power source is used so that the shadow of the soundproof wall does not hinder the light reception. A soundproof panel can be arranged, the amount of power generated by the solar cell does not decrease, and a large-capacity light emitting display is possible.
