In the event of a fire, people need to evacuate the fire quickly to ensure personal safety. However, the fire scene is often accompanied by extremely high temperature and smoke, which brings great difficulties to evacuate personnel. In order to strengthen the ability to respond to fire accidents, drones carrying fire horns began to be introduced to the scene, instructing people to evacuate quickly through broadcasts.

 How to make the UAV operate normally in a high temperature environment and broadcast clear and clear instructions is a huge challenge for the shell and various parts that need to withstand huge high temperature, especially the continuous vibration and sound at high temperature. In a fire, the temperature may exceed 1,000 degrees Celsius, so the shell, fuselage material and electronic components of the drone need to have high flame retardant and high temperature resistance to ensure its normal operation.

 Here, xiaobian to introduce you several how to ensure the efficient work of the diaphragm sound membrane under high temperature assembly solutions. When using ceramic and other rigid diaphragm, epoxy rigid glue is a good choice. Some special epoxy glue has high temperature resistance and high strength structural bonding characteristics, which has obvious effect on adhesion and reinforcement at the junction of rigid diaphragm sound membrane. When the use of rubber, paper basin, cloth and other flexible diaphragm film, ENIENT diaphragm adhesive with high strength of bonding, water, odorless, and the characteristics of high temperature resistance, it is more environmentally friendly than oil glue, better elasticity, and temperature resistance is better. More particularly, the compact adhesive film formed after the curing of the water-based adhesive is no longer afraid of water, and the finished product can be soaked in a water depth of 100 meters.

 In general, drones with fire horns need to withstand heat when the fire is evacuated. In order to ensure the normal operation of the UAV, clear and clear instructions can be broadcast, and it must be tested and improved to improve the high temperature adaptability of the UAV, fire speakers and batteries and other related accessories. In the future, with the progress of technology and the innovation of materials, it is believed that the UAV equipped with fire horns will be able to provide more effective guidance for the evacuation of fire sites under more extreme high temperature conditions and ensure the safety of personnel.
