A low-power self-heave submersible buoy based on hang glider and its working method

Abstract

The invention discloses a low power consumption self-heave submersible buoy based on a gliding wing, which belongs to the field of underwater fixed-point observation platforms. The submersible mark includes a submerged mark body, and an unpowered glider is set above the submerged mark body; the unpowered glider includes a delta wing, the axis of the delta wing is parallel to the axis of the submerged mark body, and the tip of the delta wing is at the bow of the submerged mark body Right above the upper part, the tail center of the delta wing is rigidly fixed with an empennage; a battery pack and a drive mechanism for driving the battery pack to move back and forth along the axis of the submersible body are arranged inside the submersible body; A water depth control module is provided, and the water depth control module includes an inner oil bag, an outer oil bag, an oil circuit and a hydraulic pump. In the present invention, a large-area triangular gliding wing is installed above the submersible body, and then the movable battery pack and the water depth control module are used to adjust the pitching attitude of the submersible body, so that the fluid generates a heave force on the glider, and accelerates the up and down of the submersible latent process, reducing the overall power consumption.

Description

technical field [0001] The invention relates to the field of underwater fixed-point observation platforms, in particular to a low-power self-sinking submersible buoy based on a hang glider and a working method of the submersible buoy. Background technique [0002] The submersible buoy is a system moored below the sea surface to observe the elements of the marine environment at a fixed point. It can transmit the collected information to the back-end for a long time, continuously and automatically, and is an important means of offshore monitoring. When applied, the submersible buoy is placed in a specific sea area through the mooring system. After writing the command, it dives to a certain water depth and waits for it. It rises to the sea surface at regular intervals, transmits the collected hydrological elements, and then dives to a predetermined water depth for standby. The floating and diving cycle of the submersible can be set according to actual needs. Since the submersi...

Problems solved by technology

Due to frequent floating and diving of submersible buoys, high power consumption, and the inability to use solar or wind power generation devices for power supply, it is particularly important to reduce power consumption during the floating and diving process and improve battery life
