Description

Unmanned helicopter falling water automatic floating device

This creative department relates to a device that can automatically inflate and float against unmanned helicopters (hereinafter referred to as drones) accidentally falling into the water to reduce the loss of items and data caused by the drone crashing into the sea. It mainly applies the principle of the traditional self-inflating life jacket to rescue wrecked drones, which not only melts water-soluble salt flakes when it meets water, but also drives the striker in the device to break the high-pressure gas cylinder and inflates the airbag in the device instantly. The resulting buoyancy prevents the body from sinking into the sea with the waves until the search and rescue personnel can retrieve it.

In view of the increasingly wide application range of drones, it is now widely used in various fields such as military, medical, law enforcement, surveillance, news, scientific research, etc., no matter which field is used, there are different degrees of equipment and items mounted to meet the task The drone is flying in the sea. The climate and environment factors that may be encountered are extremely complex. There may even be many microwave signals that will interfere with the flight of the drone, and it is easy to crash the drone into the sea. At present, the general drone falls into the sea, and there is no special remedy for the loss of wreckage, equipment, and data. Usually, it is when the consumables generally list the loss of consumption, but the review of the cause of the drone’s sea crash can only be judged And inference, there is no better solution, and it needs urgent improvement.

The technical characteristics of the problem-solving in this creation are mainly to provide a device that can be installed on the drone, so that when the drone falls into the water, it can automatically inflate, which in turn enables the drone to float on the water for a long period of time, not too much Quickly sink into the water. The entire set of devices can be installed without On the main column of the main beam of the man-machine, when the drone is unfortunately dropped into the water, the water is immersed in the device, which will quickly dissolve the salt in the device, so that the internal spring can push the striker, the impact gas needle pierces the high-pressure gas cylinder, and releases The high-pressure gas emitted will fill the airbag instantly, just like a life buoy, which can make the drone float on the water surface without sinking, waiting for the search personnel to find it.

The main purpose of this creation is to provide an unmanned helicopter automatic floating device for falling into the water, that is, the device will automatically inflate quickly after the drone accidentally falls into the water, so that the drone will not sink into the water, which is convenient for search personnel to find. Rescue valuable items and data; the problem it wants to solve is to improve and break through the conventional problem points. The unmanned helicopter automatic floating device for falling water integrates high-pressure gas cylinders and air bags into the device. Water-soluble salt tablets isolate the striker. When the drone falls into the water, the water will quickly dissolve the salt tablets, causing the striker to break through the high-pressure gas cylinder, and the high-pressure gas released will pour into the airbag. The buoyancy generated by the air-filled airbag makes no one. The aircraft will not sink into the sea, just like a drone wearing a life jacket. No matter what factors fall into the water, it can play a floating function, so that the drone will not sink into the water, waiting for search.

The principle of the problem-solving in this creation is mainly based on the principle that the life jacket will automatically inflate after falling into the water. It is applied to the unmanned helicopter automatic floating device for falling into the water, so that the drone is equipped with this device. Automatic inflation function, without immediately sinking into the water; mainly because the device integrates airbags, high-pressure gas cylinders, firing pins and other components.
