Hydroelectric Power Generation Drone-Linked Fire Suppression Apparatus
Technical Background
For example, there is known a drone system that transports a liquid (for example, water or a fire extinguishing liquid) from a remote place to a demand place by using a drone for the purpose of extinguishing a forest fire or the like. For example, there is known a drone system including a transport pipe through which a liquid or a gas flows, a pump device that is disposed at a remote location and supplies the liquid or the gas to the transport pipe, a top drone that holds a nozzle coupled to a distal end of the transport pipe, a plurality of pump drones that are disposed in the middle of the transport pipe and incorporate pumps for increasing a pressure of the liquid or the gas flowing through the transport pipe, and a power supply device that supplies power to the top drone and the pump drones via a power cable.
Current Problems
When power is supplied to a drone via a power cable, the cable becomes a weight. In addition, the flight distance of the drone is restricted by the length of the cable. In addition, there is a possibility that a drone equipped with a storage battery will crash unless the drone returns when the remaining amount of the storage battery becomes small. In one aspect, the present invention is directed to charging a storage battery during flight.
Means for Solving Problems
In order to achieve the above object, a drone fire-extinguishing device of the disclosure is provided. This drone fire-extinguishing device includes a drone unit that includes a storage battery and is capable of flying, a water storage unit connected to the drone unit, a power generation unit that is disposed in the water storage unit and includes a water turbine, and a connection unit that connects a hose for supplying a fire-extinguishing liquid to the water storage unit, rotates the water turbine according to the momentum of the fire-extinguishing liquid supplied from the hose connected to the connection unit during flight to cause the power generation unit to generate power, and stores the generated power in the storage battery.
