Embodiment 1

[0035] Such as Figure 1-6 shown.

[0036] A water-based UAV supply equipment, which includes:

[0037] A water surface power cabin 1, this water surface power cabin 1 provides the power required for flight as a power part of the whole equipment, and the seawater is extracted by the engine 24 installed in the water surface power cabin 1 to provide flight power; the water surface power cabin 1 also A water inlet 25, an outlet pipe 20, an auxiliary water jet 27, a seawater filtering device 28 and a propulsion device are provided. Described propulsion device is made up of two sets of identical front and back symmetrical parts, and every set of propulsion device comprises solenoid valve 21, steering mechanism 23, vector nozzle 22 and auxiliary water spray port 27, and the water inlet of vector nozzle 22 and invention machine 24 The water outlets are connected, the vector nozzles 22 are symmetrically distributed on the water surface power cabin, the solenoid valve 21 is installed...

Embodiment 2

[0043] The difference from Embodiment 1 is that four ultrasonic rangefinders are installed at the front, rear, left, and right sides of the airframe to assist the airframe to fly autonomously in severe weather conditions and complex environments.

Embodiment 3

[0045] The difference from Embodiment 1 is that the number of vector nozzles in the water surface power cabin is 1-3, and a symmetrically distributed layout is adopted; the number of nozzles in the body is 3-11, and the corresponding number and connection Both have the same number of solenoid valves, and different numbers of nozzles correspond to different layouts.

[0046] The working principle of the present invention is:

[0047] When the present invention works, the seawater is extracted by the engine 24 in the water surface power cabin 1, and the high-speed seawater reaches the water inlet pipe 13 of the body 3 after passing through the connecting hose 2, and then passes through the reversing shunt pipe 8 to convert the upward high-speed seawater Become 5 downward currents, by controlling the solenoid valve 17 installed on the outside of the chassis 10, the water spray volume and the water spray speed of each water spray pipeline can be adjusted.

[0048] Two vector nozz...

Abstract

The invention discloses a hydrodynamic force based unmanned aerial vehicle (uav) replenishment device which is mainly applicable to the field of seaborne replenishment and is characterized by mainly comprising a water surface engine compartment, a connecting hose and a fuselage, wherein an engine is arranged in the water surface engine compartment, provides power for the entire replenishment device, and pumps seawater, the pumped seawater is conveyed to the fuselage by the connecting hose and then is sprayed out through a spray tube to generate thrust and provide power for flight of the fuselage. An object loading platform is arranged on the fuselage and used for carrying and transporting seaborne goods and materials. The hydrodynamic force based unmanned aerial vehicle (uav) replenishment device solves the problems that the existing replenishment device for seaborne ships is complicated in structure, longer in previous preparation time, liable to influence of sea wave and sea breeze, and has higher requirements for synchronization of two ships and has the advantages of being high flexibility and speed and being suitable for replenishment.

Description

technical field [0001] The invention relates to a maritime replenishment technology, in particular to a water replenishment device, specifically a hydrodynamically based UAV replenishment device. Background technique [0002] Maritime replenishment refers to the use of ships, ship-borne helicopters and other equipment and their attached replenishment devices to carry out the replenishment of dry cargo, liquid cargo, ammunition and other maritime materials and personnel transportation to ships or engineering facilities. By implementing replenishment at sea, the combat radius of the ship can be expanded, and the stay time of the ship at sea can be extended, thereby reducing the dependence of the ship on the base and greatly enhancing the combat effectiveness of the ship, which has important military and economic value. [0003] In terms of technological development, the existing offshore replenishment can be divided into four types, namely horizontal replenishment, vertical re...
