Description

{Water overflow prevention structure}

The present invention relates to a wave prevention structure, and more specifically, to a wave prevention structure installed in a vehicle to simultaneously accommodate an electric vehicle in which a fire has occurred and water for extinguishing the fire, and to prevent water from overflowing when the vehicle is moving.

In general, an electric vehicle is a vehicle that is powered by electricity, and the vehicle is driven by a motor that rotates with electricity stored in a battery.

Electric vehicles have the advantage of being environmentally friendly in terms of fuel as they use electricity, have the advantage of low fuel costs compared to petrol costs, produce less vehicle noise, and have the advantage of preventing environmental pollution by not emitting any exhaust gases, so they are widely sold in recent years.

However, recently, fires have been occurring frequently in electric vehicles that are widely sold and in operation. The most common cause of fires in electric vehicles is thermal runaway, where impurities enter the battery's separator, damage the separator, and rapidly increase the temperature, causing the entire battery to swell, resulting in an explosion and fire. Fires can also occur due to mechanical failures, traffic accidents, or unknown causes.

A conventional electric vehicle fire extinguishing container unit is intended to extinguish a fire by loading a vehicle on which a fire has broken out, and includes a container body having a space for accommodating a vehicle, a pipe for supplying water into the space for extinguishing the fire, a rear frame positioned on a vehicle entry line, wherein a portion of the rear frame is open to allow vehicle entry through the open entrance, an opening/closing door rotatably installed on the rear frame of the container body so as to selectively open/close the entrance, a rotating means for rotating the opening/closing door relative to the container body, and a lift that is installed so as to be elevating on the bottom frame of the container body so as to rise to the lowest position of the open entrance of the rear frame so as to place a vehicle entering through the entrance, and then lowers the lift to its original position after the vehicle is loaded.

However, in the case of conventional electric vehicle fire extinguishing container units, there was a problem that the water contained to extinguish a fire could overflow due to shaking or impact caused by the movement of the vehicle when the vehicle was loaded and moved.

Meanwhile, the background technology described above is technical information that the inventor possessed for deriving the present invention or acquired during the process of deriving the present invention, and cannot necessarily be considered as publicly known technology disclosed to the general public prior to the application of the present invention.
