Abstract

A traffic warning device capable of reducing maintenance costs is provided. The main body has an internal storage space 201 for storing an energy storage power supply and a controller. The warning light 21 is a light emitting diode 211 fitted so as to surround the main body in the circumferential direction. When the stored energy of the energy storage power supply is insufficient, the controller 24 controls the energy storage power supply so that it receives electric energy converted by the solar panel and performs charging, and the weather is good. If not, the energy storage power supply is controlled to supply power to the alarm light. The traffic warning device itself has an energy storage power supply, so it is not necessary to receive power supply from an external power source via an electric line, and the occurrence rate of damage can be reduced. However, the maintenance cost can be effectively reduced because it is only necessary to inspect the damaged part of the accessory part inside the traffic warning device. [Selection] Figure 3

Description

The present invention relates to an alarm device, and more particularly to a traffic alarm device capable of reducing maintenance costs.

Usually, when there is road construction, construction work or road obstacles, it is common to install a road cone to call attention to pedestrians and vehicles in order to prevent accidents from occurring. However, such a road cone can achieve a predetermined warning effect during the daytime, but when the night or the weather is bad, the warning effect is greatly reduced due to poor visibility. In order to solve such a problem, a method has been proposed in which a light reflecting sheet for traffic warning is attached on a road cone to reflect the light of the vehicle to achieve the warning purpose. However, when the vehicle is not approaching or the weather is not good, the light reflecting sheet on the road cone loses its warning function. For this reason, a warning light for traffic warning is installed on the road cone instead of the light reflection sheet, and a device for calling attention to pedestrians and vehicles by the light from the warning light has been proposed. The function is not affected by the weather.

FIG. 1 is a diagram showing a prior art in which a road cone provided with a warning light is a traffic warning device. As shown in FIG. 1, a mounting hole 101 for mounting a warning light 11 is provided on each of a plurality of load cones 10. Each of the warning lights 11 is provided with a mounting column 111 and is mounted on the load cone 10 by a combination of the mounting hole 101 and the mounting column 111. The warning lights 11 are electrically connected to each other by an electric line 12 exposed to the traffic environment, and emit light by receiving power from an external power source (for example, power generation equipment) 13 through the electric line 12. Call attention to pedestrians and vehicles. However, since the electric circuit 12 exposed to the outside is often damaged by wind, sunlight, rain, or a traffic accident, the external power source 13 cannot supply power to the alarm lights 11. The point to be noted here is that due to the demand for traffic warnings, the electric circuit 12 is generally extended extremely long under the influence of the size of the construction area. The longer the length, the easier it is for damage to occur, and it becomes difficult to find the damaged part, which increases the maintenance cost.

As described above, providing a traffic warning device that can reduce maintenance costs is an extremely important issue to be solved in the industry.

Therefore, in view of the circumstances as described above, it is an object of the present invention to provide a traffic warning device that can reduce maintenance costs.

In order to solve the above-mentioned problems and other problems, the present invention comprises a main body which is a hollow columnar body having an accommodating space therein and at least one strip-shaped light emitting diode, and surrounds the main body in the circumferential direction. Alarm light fitted in such a manner, a solar panel provided at the top of the main body for converting solar energy into electric energy, provided in the housing space, and electrically connected to the alarm light and the solar panel, respectively. An energy storage power supply connected to the storage space and electrically connected to the energy storage power supply, and the energy storage power supply is charged by receiving the electric energy converted by the solar panel. Or a controller for controlling to power the alarm light. To provide a traffic warning device for the butterflies.

The main body may further include a groove for fitting the alarm light so as to surround the main body in a circumferential direction of the main body. The traffic warning device may further include an electrical energy input port that is electrically connected to the energy storage power supply and receives external electric energy so that the energy storage power supply can be charged. The traffic warning device further includes a stand provided in the main body and having a cross section larger than the cross section of the main body, and a plurality of joints are formed in a peripheral portion of the stand so as to surround the main body. The main body may be overlapped by a plurality of annular bodies. The stand may include a positioning column for positioning each annular body on a surface facing the main body.

The traffic warning device may further include a light transmission plate provided above the solar panel and joined to the top of the main body. The traffic warning device may further include a variable resistor that is provided in an electrical connection route between the energy storage power supply and the warning light and adjusts the light emission intensity of the warning light. The energy storage power supply may include a lithium iron phosphate battery. The traffic warning device receives the electric energy converted by the solar panel by the energy storage power feeder or supplies power to the warning light so that the controller can control the power based on ambient light intensity. And a light detector electrically connected to the device for providing ambient light intensity detection information to the controller. The traffic warning device is electrically connected to the controller so that the controller can control the receipt of electric energy converted by the solar panel by the energy storage power feeder or the power supply to the warning light. It may further include a manual switch.

As described above, due to the cooperation between the solar panel and the energy storage power supply, the traffic warning device according to the present invention charges the energy storage power supply using solar energy when the environmental light source is sufficient. If there is a shortage of environmental light sources, it is possible to perform traffic warning work by supplying power to the warning light via the energy storage power supply. The traffic warning device itself has an energy storage power supply and does not need to be supplied with power from an external power source via an electric line, so that the occurrence rate of damage can be reduced, even if damage occurs. However, the maintenance cost can be effectively reduced because it is only necessary to inspect the damaged part of the accessory part inside the traffic warning device.
