Embodiment Construction

[0024] Specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0025] The cable-free seabed observation system of the present embodiment includes two parts of the above-water monitoring unit and the seabed observation platform, such as Figure 5 shown. Among them, the water monitoring unit can be arranged on the scientific research ship, including the upper computer and the underwater acoustic communication machine. The upper computer communicates with the submarine observation platform through the underwater acoustic communication machine, realizes the real-time monitoring of the operation trajectory of the submarine observation platform, the height from the seabed, the underwater working environment, and the working state, and controls the submarine observation platform by issuing remote commands Perform operations such as slowing down, penetrating, and recovering, and process, display, and store and m...

Abstract

The invention discloses a cable-less seabed observation system suitable for the whole sea depth, which comprises a water monitoring unit and a seabed observation platform. The seabed observation platform comprises a frame-type main body and a floating body, a wing plate, a floating ball cabin, a leveling mechanism, a counterweight and a release mechanism installed on the frame-type main body. Thefloating balloon cabin sealing system circuit is configured to deploy the wing plate when the seabed observation platform descends to a set height from the seabed, so that the seabed observation platform can land steadily. The leveling mechanism adjusts the seabed observation platform to stand horizontally on the seabed when the frame-type main body reaches the seabed. The release mechanism discards the counterweight to realize recovery after the underwater operation of the seabed observation platform is completed. The seabed observation platform of the invention adopts the cable-free laying mode, is not limited by the cable length, and the working water depth can reach 11,000 meters or more, so that the seabed observation of the whole sea depth can be realized.

Description

technical field [0001] The invention belongs to the technical field of ocean observation, and in particular relates to a seabed observation system applicable to sea areas of different depths. Background technique [0002] At this stage, marine research has entered the era of full-sea depth. The sea area with a water depth ranging from about 6000 m to 11000 m is called "Hadal trench" by scientists and is the deepest ocean area on earth. This area is mainly distributed on the edge of the continent and is composed of trenches. Although it only accounts for 1%-2% of the global seabed area, its vertical depth accounts for 45% of the total depth of the ocean, which is of great significance in the marine ecosystem. At present, the research on the sea bucket abyss has become the latest frontier field of marine research, which also marks that marine science has entered the era of full-sea deep scientific research. [0003] With the continuous development of the submarine observation...
