AI Technical Summary

Technical Problem

Fire trucks struggle to reach large-scale fires effectively due to chaotic road conditions, necessitating the use of drones for rapid fire extinguishing, but existing drones lack effective cooling mechanisms for their electronic components to operate in high-temperature environments.

Method used

The drone's electronic components, including the gyro, GPS, computer, and servo motor, are cooled using ice water to evaporate and are covered with heat-insulating and radiation-reflecting materials, with specific components like the motor having water vapor escape holes.

Benefits of technology

The cooling method enables the drone to function effectively in hot conditions, ensuring the components can withstand high temperatures and maintain operation.

Abstract

This system provides a firefighting method using drones to quickly reach the scene when roads are congested and fire trucks cannot travel as planned. [Solution] A drone capable of flying can go directly to the scene. In other words, a firefighting drone must be developed. At that time, the drone must be able to withstand heat. This method devises a cooling method to withstand heat. Electronic equipment is cooled with ice water, and electric motors are cooled by the evaporation of water. This can also be done using thermocouples.

Disclosure of the Invention

Problems to be Solved by the Invention

[0003] In case of a large-scale fire, the roads are in chaos and the fire trucks cannot run as expected. At that time, in order to quickly reach the scene, a drone flying in the air is suitable.

Means for Solving the Problems

[0004] In this machine, the parts to be cooled are the gyro, GPS, computer, servo motor, and generator. In order for the drone to withstand heat, it is necessary to cool electronic devices such as the computer and motors. The electronic devices are cooled with ice water. The motors are cooled by sending water to evaporate.

Effects of the Invention

[0005] When the electronic devices are cooled, the drone can withstand heat and can operate even in hot air.

Best Mode for Carrying Out the Invention

[0006] The computer is cooled through a thin heat insulating material. The gyro and GPS are also wound with a material like a heat insulating material TIFF2026122869000002.tif21165 and immersed in water to cool the motor. The outer periphery of the motor is covered with a heat insulating material and a radiation reflecting material. Small holes are opened in the covering of the motor. Water vapor escapes from there. If other parts are necessary, they are covered with a heat insulating material and a radiation reflecting material.

Examples

[0007] A laser gyroscope can be used instead of a gyro. A stepper motor can be used instead of a servo motor. The generator will be driven by a turbine engine directly connected to it. The fuel control valve will be driven by a servo motor. Cooling can also be done with a thermocouple. [Brief explanation of the drawing]
