Unmanned small-size floating device

Abstract

The invention discloses an unmanned small-size floating device which is characterized in that a floating assembly and a landing assembly arranged separately; a floating airbag and a working load are arranged in the floating assembly; an air storage unit and a control unit are arranged in the landing assembly, and an air storage tank in the air storage unit inflates the floating airbag through a cut-off switch, a pressure reducing valve and a check valve at the right moment under the control of the control unit; and the floating assembly lifts off and the landing assembly lands after air inflation is completed, and the floating assembly and the landing assembly are connected via a cotton rope. The device provided by the invention has high maneuverability, convenience for carrying and throwing, no need of manual intervention after outside trigger signal starting work, light weight and small size, and the unmanned small-size floating device can be quickly applied to sea surfaces or mountains with complex terrain by using various platforms in order to meet the needs of monitoring, communication and the like under emergency conditions such as earthquake relief work, frontier defense, counter terrorism and the like.

Description

technical field [0001] The invention relates to a small floating device capable of being carried and dropped and unmanned, and belongs to the field of aircraft. Background technique [0002] In addition to satellites and aircraft, airships, tethered balloons, etc. can also be used as application platforms for aerial observation, target detection, and communication relay equipment used in specific regions. Airplanes consume a lot of fuel and stay in the air for a short period of time, so they are not suitable for continuous long-term use; satellites can be used for a long time, but their orbits are high, and the observation accuracy is often not achieved. The operating costs of both are relatively high; therefore, for a specific area And for continuous monitoring or other continuous applications during a specific period of time, airships or tethered balloons are a good choice. [0003] The airship is filled with inert gas, such as helium, and relies on the buoyancy of the in...

Problems solved by technology

However, tethered balloons are not as maneuverable as airplanes or airships, and multi-person operations are required when the balloon is inflated. If it is to be used on the sea or in mountainous areas with complex terrain, it is often inconvenient, especially in some areas such as earthquake relief or anti-terrorism. And other special occasions, the system takes a long time to set up and the response speed is relatively slow
