Problems solved by technology

However, the geological conditions of the seabed are complex, and the actual attitude of the underwater platform deployed from the ship on the seabed is difficult to control. For the muddy bottom, if the platform is deployed with the correct posture at the beginning, the bottom may subside over time, causing the platform to be skewed. It is even more difficult to control the bottoming attitude of the platform
The active attitude adjustment platform using attitude sensor feedback combined with servo motor drive is relatively expensive, and it takes up limited space and power in the underwater instrument cabin, which is not ideal.

Embodiment Construction

[0017] The present invention will be described in detail below with reference to the accompanying drawings and examples.

[0018] as attached figure 1 As shown, the present invention provides a posture self-stabilizing underwater platform, the platform as a whole includes an instrument cabin 1, a universal bracket 2 and a base 3, as attached figure 2 As shown, the base 3 includes a counterweight 4, a chassis 5, claws 6, a torsion spring 7, and a flap 8; there are three mounting holes for installing the flap 8 on the chassis 5, and the flap 8 is installed on the chassis through the torsion spring 7 and the rotating shaft On the top, the flap can be flipped down 90° by overcoming the force of the torsion spring, and the torsion spring keeps the flap in a state of being horizontally attached to the chassis 5 under the elastic force. The three claws 6 are detachably connected to the lower surface of the chassis, and the detachable counterweight Blocks 4 are evenly arranged on th...

Abstract

The invention discloses an attitude self-stabilizing underwater platform, which belongs to the technical field of marine engineering. The platform includes a base, a universal bracket and an instrument cabin; the base and the instrument cabin are movably connected together through the universal bracket, and the platform is hoisted into the water as a whole and the base realizes the bottoming, and the universal bracket is based on the bottom angle of the chassis and The instrument cabin adjusts its own angle in the positive buoyancy direction, so as to adapt to the buoyancy attitude direction of the instrument cabin itself. The invention can automatically adapt to the underwater terrain and maintain the posture under the condition of no power, and can also adapt to platform recovery in two kinds of underwater environments of sediment and rock.

Description

technical field [0001] The invention relates to a posture self-maintaining platform for underwater information monitoring and collection, in particular to a platform structure capable of automatically maintaining a stable posture of its instrument cabin in a certain direction at the bottom of the water through its own buoyancy, belonging to the technical field of marine engineering . Background technique [0002] Some underwater platforms in marine engineering need to keep their posture stable at the bottom of the water, so as to ensure that their internal detection buoys, underwater acoustic beacons, and indicating buoys can be released normally through miniature winches, or that internal sensors, etc. conform to the measurement direction. Require. However, the geological conditions of the seabed are complex, and the actual attitude of the underwater platform deployed from the ship on the seabed is difficult to control. For the muddy bottom, if the platform is deployed wit...
