Description

The present invention relates to a guardrail with a grass protection device. Specifically, it prevents the guardrail for safety measures from being hidden by weeds and makes the position of the guardrail easier to understand.
The present invention provides an ultraviolet LED for irradiating downward at the lower end of the rail portion of the guard rail, and a photovoltaic power generation panel at the upper end of the rail, which serves as a power source for the ultraviolet LED connected to the panel. Guardrail with device.

  The guardrail indicates a road edge for safe driving, and has a function as an accident buffering device for preventing a major accident when a driving operation is mistaken. However, because there are many mountain roads such as highways, weeds grew and regular weeding work was necessary.

On the other hand, as proposed in Japanese Patent Publication No. 2006-73230 (Patent Document 1), a herbicidal method capable of controlling difficult-to-control weeds such as kudzu has been proposed.
This herbicidal method realizes at least one of killing and controlling the growth of vine difficult-to-control weeds using ultraviolet rays. For example, by directly irradiating the difficult-to-control weeds with ultraviolet rays, the hard-to-control weeds are killed, or by irradiating ultraviolet rays to the space where the invasion of the difficult-to-control weeds is avoided, Control growth. In this way, vine-type difficult-to-control weeds are targeted for weed control, and the control-control weeds are killed and controlled for growth.
Although this method seems to be extremely effective, there is no mention of improving the visibility of the guardrail or preventing accidents.

  In addition, with the development of solar panels and the widespread use of LED ultraviolet light, these have become inexpensive and easily available.

  In addition, it was often left unattended due to the lack of manpower and frequency of weed control work.

  In view of such a situation, the present invention has been devised, the ultraviolet light of the ultraviolet LED illumination has a wavelength of 200 nm or more and 280 nm or less. A guard rail with a weedproof device, characterized in that a photovoltaic power generation panel is provided at the upper end of the rail and used as a power source for the ultraviolet LED connected to the panel.

  Also, as a solution to the extreme danger and difficulty of weeding around the guardrail support as patent publication 2006-199981 (patent document 2), weeding is eliminated without growing the weed near the guardrail support. Therefore, it has been proposed that a skirt-like bush and plate are attached to the lower part of the outer periphery of the guardrail support to eliminate weeds, but it does not use ultraviolet LEDs but mechanically prevents grass. Therefore, there seems to be anxiety about long-term use.

Japanese Patent Publication No. 2006-73230 Japanese Patent Publication No. 2006-199981

  The problem described above is to provide a guardrail with a weedproofing device that automatically prevents weeds from the ground surface at the lower end of the guardrail in order to ensure the visibility of the guardrail.

  Furthermore, it improves the visibility of guardrails and contributes to the prevention of accidents on highways.

  In summary, an ultraviolet LED illumination having a wavelength of 200 nm or more and 280 nm or less, which is an ultraviolet light region by LEDs, and a solar panel are used as a power source of the illumination.

Means for solving the idea

  The present invention solves such conventional problems, and provides a guardrail with a weedproofing device that automatically prevents weeds from the ground surface at the lower end of the guardrail in order to ensure the visibility of the guardrail. It is.

Effect of device

  Since it uses a solar panel as a power source and is grass-proof by ultraviolet LED illumination, it is an eye that improves road safety and provides inexpensive measures.

  It is a partial front view of the guardrail which shows the Example of this invention.   It is a partial front view of the installation condition containing the guardrail which shows the prior art example of this invention.

  The present invention will be described according to an embodiment.

  FIG. 1 shows a guardrail with a grass protection device according to the present invention. The LED ultraviolet rays of ultraviolet LED illumination have a wavelength of 200 nm or more and 280 nm or less. A guard rail with a weedproof device, characterized in that a photovoltaic power generation panel is provided at the upper end of the rail and used as a power source for the ultraviolet LED connected to the panel.

The ultraviolet LED illumination used here is the same as the ultraviolet ray disclosed in Patent Document 1 that is generally known. According to Patent Document 1, the ultraviolet light may have a wavelength with a maximum light emission intensity of around 230 nm. For example, if a rare gas fluorescent lamp enclosing xenon gas is used, ultraviolet light having a peak wavelength of 230 nm and a continuous spectrum in the wavelength range of 200 nm to 280 nm can be obtained. Thus, a high herbicidal effect on difficult-to-control weeds can be obtained using a practical light source.
Furthermore, as one aspect of the herbicidal method, at least one of plant killing and growth control is realized using ultraviolet rays having a wavelength of 200 nm to 280 nm.
Thus, by using ultraviolet rays (UV-C) having a wavelength of 200 nm or more and 280 nm or less, plant death and growth control can be effectively performed.

  Fig. 2 is a photograph showing the state before the implementation of the present invention. The weed weed obstructs the visibility of the guardrail, and periodic weeding work is necessary to ensure safety. It is also necessary to ensure the safety of the work itself. Met.

Hereinafter, preferred embodiments of the present invention will be described.
The guardrail is installed on the side edge of the road for safety so that it can be clearly distinguished from other roads and to prevent accidents. However, it is particularly sensitive to dangerous mountain side slopes and steep cliffs. It is also installed at the border. In these cases, it is effective to install the guard rails with the grass protection device of the present invention only at the main points, and it can be installed at low cost.

  The ultraviolet LED illumination 2 for irradiating downward is provided on the rail lower end 1 of the guard rail A, and the photovoltaic power generation panel 4 is provided on the rail upper end 3 to serve as a power source for the ultraviolet LED illumination 2 connected to the panel 4. It is a guardrail with a weedproof device.

  Here, as the LED light source, for example, the one proposed in Japanese Patent Application No. 2008-103791 or a commercially available ultraviolet LED lamp is used, but mounting with a tape-like one is simple.

  As described above, the present invention is extremely easy for road safety management and is also useful for preventing traffic accidents. In addition, weeding work is not necessary, and not only can a safe road be maintained at all times, but also it is useful for ensuring deadness.

  The present invention is provided to the road steel industry that produces and sells guardrails and public road industries such as expressway companies.
