Embodiment Construction

[0037] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0038] Such as Figure 1~6 As shown, the release and dump system for deep-sea structures includes acoustic release device 1, automatic decoupling device 2, fairlead 3, decoupling bracket 4, long-load dump hook A5, long-load dump hook B6, ballast 7 and deep-sea structure frame 8, wherein the acoustic release device 1 and the automatic decoupling device 2 are respectively installed on the deep-sea structure frame 8, and the automatic decoupling device 2 is located obliquely below the acoustic release device 1; Each set of load-throwing actuators includes a long load-throwing hook A5 and a long load-throwing hook B6, and the ends of each set of long load-throwing hooks A5 and B6 are respectively hinged and fixed on the frame 8 of a deep-sea structure. The decoupling bracket 4 of the hook is hung with ballast 7 respectively, and the head ends of the long hook A5...

Abstract

The invention relates to a long-term fixed point observation device for a deep-sea ecological process. The long-term fixed point observation device comprises a release and load rejection system, and abattery cabin, a control cabin, a buoyancy ball, an iridium satellite beacon, a light beacon, an ultra-short baseline transponder and a compass cabin arranged on the release and load rejection system. According to the device disclosed by the invention, two load rejection schemes of an acoustic release transponder and an automatic unhooking device are adopted, and delayed load rejection can be performed by adopting the automatic unhooking device when the acoustic load rejection means fails. According to the device, load rejection can be released by virtue of the acoustic release transponder, and can also be released by virtue of an emergency load rejection mechanism. The emergency load rejection mechanism and the acoustic release transponder are in a series form. When the acoustic releasetransponder fails and cannot perform load rejection, the emergency load rejection device can be started to realize load rejection floating, and the safety of the equipment operation is improved.

Description

technical field [0001] The invention relates to a long-term fixed-point observation system for deep-sea ecological processes, in particular to a long-term fixed-point observation device for deep-sea ecological processes. Background technique [0002] As an important part of the marine system, the deep sea has special environments such as abyssal plains, seamounts, hydrothermal fluids, and cold springs, which lead to drastic changes in seabed topography and physical and chemical factors, thereby affecting the dynamics and thermal processes of the deep ocean, and thus giving birth to a unique ecosystem. . However, due to the lack of survey equipment and means, the current understanding of the deep-sea system is mostly based on the results of one or several sampling surveys, and the lack of continuous and systematic observation data leads to a lack of systematic process research and mechanism understanding of the deep-sea environment and its habitats. . The demand for a devic...
