Description

A miniature multi-rotor aircraft that can take off and land on water and land and charge itself

technical field

The invention belongs to the technical field of small aircraft, in particular to a miniature multi-rotor aircraft capable of taking off and landing amphibiously and charging itself.

Background technique

Micro multi-rotor aircraft is being widely used in aerial photography, environmental detection, traffic monitoring, power inspection and on-site rescue and other fields, and has broad military and civilian prospects. For now, most micro multi-rotor aircraft are limited to take-off and landing on land. For long-distance water shooting, patrol inspection and other tasks, it is easy to cause insufficient power or other failures on the way, causing the micro multi-rotor aircraft to fall into the water, thus limiting the use of micro multi-rotor aircraft. Application and development of rotorcraft.

Contents of the invention

The invention proposes a miniature multi-rotor aircraft that can take off and land on water and can be charged autonomously, with the purpose of solving the problems of taking off and landing on water and autonomous charging of the miniature multi-rotor aircraft, and expanding its application range.

The technical scheme adopted in the present invention is:

The aircraft itself is loaded with a GPS module, and is equipped with three parts: an inflatable module, a charging module and a detachment module.

The inflatable module is installed on the landing gear at the bottom of the multi-rotor aircraft and is composed of a gas generator, a micro electronic valve, a gas transmission tube and an air bag; the gas generator is installed on the connecting rod of the landing gear, and the two air bags are respectively installed on two In the groove on the bottom bar of the landing gear; the gas generator is connected to the two airbags through the micro electronic valve and the gas transmission tube; the GPS module is used to query the map to know whether there is water under the aircraft, and if so, the airbag is automatically inflated through the inflation module;

The charging module is composed of a miniature solar receiving board, an energy management system and a battery; the miniature solar receiving board is arranged on the surface of the aircraft frame; after landing on water, the energy management system automatically controls the miniature solar receiving board to charge the battery, and accumulates energy for it to take off again. Energy: According to the location information provided by the GPS module, calculate the distance between it and the nearest land, and the battery energy required to fly to the land, so as to determine the charging time of the charging module;

The detachment module is composed of four electric locks; two electric locks connected to the airbag are installed on each landing gear bottom rod; when the aircraft takes off from the water again, the electric locks are opened to release the airbag from the aircraft .

The beneficial effect of the present invention is that: through the inflatable module, the charging module and the detachment module, the function of land and water take-off and landing is safely realized. The airbag is contracted before the water landing, and the airbag is released after the water landing. The whole flight has light weight, low resistance, low power consumption, and stable water landing. It can be widely used for shooting over water, environmental detection, and on-site rescue. It has broad prospects. .

detailed description

The present invention provides a miniature multi-rotor aircraft that can take off and land on water and land and can be charged autonomously. The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

Taking the quadrotor aircraft as an example, the structure is shown in Figure 1. Install the inflatable module, the charging module and the three parts from the module on the micro multi-rotor aircraft.

The inflatable module is installed on the landing gear at the bottom of the multi-rotor aircraft, and is composed of a gas generator 1, a micro electronic valve 2, a gas transmission tube 4 and an air bag 6; the gas generator 1 is installed on the connecting rod 3 of the landing gear, and the two air bags 6 are respectively Installed in the grooves on the bottom rods 5 of the two landing gears, the gas transmission tube 4 is fixed on the connecting rod 3 of the landing gear by bolts; the gas generator 1 is connected to the two airbags 6 through the micro electronic valve 2 and the gas transmission tube 4 ; The flight control system controls the opening and closing of the miniature electronic valve 2 . When the multi-rotor aircraft receives a landing signal or detects that the battery power is lower than the power required for the aircraft to fly out of the water, it will use the GPS module to query the map based on the onboard GPS information to know whether there is water below it. Inflate.

The charging module is composed of a miniature solar receiver board, an energy management system and a battery; the miniature solar receiver board is arranged on the surface of the aircraft frame; after landing on water, the energy management system automatically controls the miniature solar receiver board to charge the battery and accumulate energy for its take-off again. According to the onboard GPS position information, the multi-rotor aircraft calculates the distance between its nearest land and the battery energy required to fly to the land, so as to determine the charging time of solar energy.

The disengagement module consists of four electric locks; two electric locks connected to the airbag 6 are installed on each landing gear bottom bar 5; lifted. In order to recover the airbag, the airbag sends a signal to the surroundings so that the signal can be confirmed and recovered.
