Description

Technology Field

[0001] The present invention relates to a solar power system, and more specifically, to a smart median solar power system that utilizes the top of a road median as a support frame to produce solar renewable energy, thereby making the road smart, and supplies the surplus power to surrounding facilities, which can be utilized to implement 'RE100 (Renewable Energy 100%)' and respond to Green Taxonomy. Background Technology

[0002] Generally, a median refers to a support installed in the center of a road with four or more lanes. By installing a median, head-on collisions between vehicles traveling in both directions can be prevented, making it easy to use.

[0003] Median barriers, which are widely installed on expressways as well as high-speed automobile-only roads, promote driver safety; however, median barriers made of concrete pose aesthetic maintenance issues. Furthermore, with the recent increase in traffic volume and the construction of new mountainous expressways, casualties from secondary accidents caused by black ice are on the rise. To prevent such accidents, the issue of ensuring a smooth supply of large-scale power is emerging to install and operate heating cables, traffic signs, and electric vehicle charging facilities.

[0004] In addition, although casualties from secondary accidents such as black ice are increasing day by day, supplying large-scale electricity to such dangerous areas presents realistic problems, including the enormous budget required and forest destruction caused by the installation of transmission towers.

[0005] In addition to this, there remains the task of utilizing highways with good sunlight as sites for renewable energy solar power generation to produce electricity and smarten highways to suit the era of autonomous vehicles, as well as addressing renewable energy to realize 'RE100 (Renewable Energy 100%)' and respond to Green Taxonomy, which must be resolved globally. The problem to be solved

[0006] The objective of the present invention, which aims to solve the aforementioned problems, is not limited to improving the issues of median strips to resolve power supply problems, but rather to effectively utilize median strips. Specifically, the invention provides a smart median strip solar power system that installs solar panels on the top of the median strip to generate and store electricity, utilizes it to implement smart roads, and supplies electricity to surrounding facilities. means of solving the problem

[0007] In a smart median strip solar power system according to the present invention for achieving the purpose described above, a solar panel installed on the top of the median strip to produce electricity from solar heat, a battery that accumulates electricity produced by the solar panel, and a light-emitting body that emits light using the electricity accumulated in the battery are configured on one side of the solar panel.

[0008] In addition, the above-mentioned solar panels are configured such that multiple units are connected to the grid at intervals to form a solar power generation section, and the generated electricity is transmitted to and stored in an energy storage device.

[0009] The electricity from the energy storage device accumulated in this way is connected to surrounding transportation facilities and heating wires via a connection part to an inverter installed on the inner side of the solar panel and controlled, and is configured to transmit the surplus power to an energy storage device (ESS) and a substation that is discharging.

[0010] Here, the power stored in the above substation can be configured to be supplied to surrounding facilities or industrial infrastructure through transmission lines or to be grid-connected to another substation.

[0011] The above solar panel is characterized in that the connecting part can be formed as an elastic part made of a flexible material.

[0012] In addition, the solar panel is characterized by having a guide rail formed on one side and a traffic guidance display means created.

[0013] In addition, management and maintenance can be facilitated by configuring a cleaning vehicle that inspects the solar panel and sprays cleaning water to move along the solar panel and clean the module.

[0014] In addition, it is characterized by the installation of sensors in black ice sections to indicate the danger of black ice, which control the operation of heating cables and warning lights.

[0015] Here, the warning light indicating the black ice danger is set to operate from a predetermined distance behind, and the heating power for the black ice section can be supplied through grid-connected energy storage devices.

[0016] In addition, the smart median solar power system according to the present invention can apply an automatic wireless charging system while a vehicle is in motion, and is characterized by being able to automatically charge electricity to a vehicle through a wireless charging transmitting pad installed on one side of the median or the solar panel on the top of the median and a wireless charging receiving pad of the moving vehicle.

[0017] The above-described solar panels are characterized by being configured to store electricity in a battery formed by connecting multiple panels into a single block, and being able to transmit the electricity to a grid-connected energy storage device through a transmission line. Effects of the invention

[0018] The smart solar median strip system according to the present invention can establish the foundation for smart roads by utilizing the median strip as a renewable energy power plant.

[0019] In addition, it has the advantage of minimizing casualties caused by accidents by using solar cells to store electricity using median strips without requiring an external power supply, and supplying power to light-emitting devices and black ice sections such as mountainous terrain using the stored electricity.

[0020] In addition, by utilizing an electric vehicle wireless charging system in the median solar system, there is the advantage of enabling vehicles to charge electricity while driving.

[0021] Furthermore, the invention has the effect of enabling the realization of 'RE100 (Renewable Energy 100%)' and the response to Green Taxonomy by transmitting the surplus power, which has not been achieved through the aforementioned objectives, to a substation via transmission lines to supply renewable energy to surrounding industrial infrastructure.
