Abstract

The invention discloses a hood-sealed waterproof pitot tube, which comprises a sealed cabin, the two ends of the sealed cabin are respectively provided with a first opening and a second opening, and a pitot tube is arranged in the sealed cabin, and the pitot tube is connected from the first One opening end is inserted into the airtight cabin, and a sealing mechanism is provided between the first opening and the pitot tube; a hatch door that can be opened and closed is provided on the second opening, and the first opening is flexibly connected with the pitot tube; The cabin is provided with a drive mechanism that drives the airtight cabin to slide on the pitot tube, and a linkage mechanism that drives the door to open and close when the airtight cabin slides on the pitot tube is provided between the hatch door and the pitot tube. This solution is aimed at the use of water-air dual-purpose drones. When the drone enters the water, it relies on the airtight cabin to close the pitot tube. When it leaves the water, the airtight cabin can be opened to restore the pitot tube. The invention adopts the sealing rubber sleeve, which can realize dynamic sealing and achieve waterproof effect.

Description

technical field [0001] The invention relates to the field of aviation technology, in particular to a hood-sealed waterproof pitot tube. Background technique [0002] With the development of science and technology, unmanned aerial vehicles are not only used in aerial fields such as terrain surveys, route inspections, and military reconnaissance. Many universities and research institutes have rushed to develop water-air dual-use unmanned aerial vehicles. As an important device for measuring the flight speed of drones, pitot tubes are widely used in various types of drones, but ordinary pitot tubes are not waterproof and cannot be directly applied to water-air dual-purpose drones. In order to meet the needs of water and air dual-purpose UAVs, it is of great significance to study waterproof pitot tubes. Contents of the invention [0003] Aiming at the above-mentioned deficiencies in the prior art, the present invention provides a highly reliable hood-sealed waterproof pitot t...
