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

A water-powered UAV supply device, mainly used in the field of maritime supply. It is characterized in that it mainly includes a water surface power cabin, a connecting hose and a fuselage. Among them, the water surface power cabin has a built-in engine, which is used as the power of the entire supply device. The engine extracts seawater and transports it to the body through a connecting hose, and then sprays it out through the nozzle to generate thrust to provide power for the flight of the body. The body is equipped with a loading platform for the handling of marine materials. The present invention can solve the problems of complex structure of the replenishment device existing in the replenishment between ships at sea, long pre-preparation time, easy to be affected by waves and sea wind, and high requirements for synchronization of the two ships, etc., and has high flexibility, fast speed and suitable replenishment Etc.

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...
