Low-power-consumption self-heaving type subsurface buoy based on hang glider and working method of low-power-consumption self-heaving type subsurface buoy

Abstract

The invention discloses a low-power-consumption self-heaving submerged buoy based on a hang glider, and belongs to the field of underwater fixed-point observation platforms. The submerged buoy comprises a submerged buoy body, wherein an unpowered hang glider is arranged above the submerged buoy body; the unpowered hang glider comprises a delta wing, the axis of the delta wing is parallel to the axis of the submerged buoy body, the tip of the delta wing is located over the bow of the submerged buoy body, and an empennage is rigidly fixed to the center of the tail of the delta wing. A battery pack and a driving mechanism used for driving the battery pack to move back and forth in the axis direction of the submerged marker body are arranged in the submerged marker body. A water depth control module is arranged on the bow portion of the submerged buoy body and comprises an inner oil bag, an outer oil bag, an oil way and a hydraulic pump. According to the underwater buoy, the large-area triangular hang gliders are additionally arranged above the underwater buoy body, and the pitching attitude of the underwater buoy body is adjusted in cooperation with the movable battery pack and the water depth control module, so that the fluid generates heaving force on the hang gliders, the floating and diving processes of the underwater buoy are accelerated, and the total power consumption is reduced.

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
