Small waterplane double-hull or multi-hull ship sea well opening and closing device and using method thereof

Abstract

The invention relates to a small waterplane double-body or multi-body ship sea well opening and closing device and a using method thereof.The small waterplane double-body or multi-body ship sea well opening and closing device comprises two or more submerged bodies arranged at intervals, the upper portions of the submerged bodies are jointly connected and provided with a connecting bridge, and a sea well is formed in the position, penetrating through the connecting bridge between every two adjacent submerged bodies, of the connecting bridge; a test equipment bracket is mounted on the top surface of the connecting bridge at an upper orifice of the sea well, and a box-type platform is mounted on a wet deck on the bottom surface of the connecting bridge; the box-type platform is driven by the opening and closing driving mechanism to move to the position under the sea well to close the sea well, or the box-type platform moves reversely to open the sea well; the self-locking mechanism is used for locking the movement of the box-type platform when the sea well is completely opened or closed; therefore, the opening and closing of the sea well can be realized, the use of test equipment above is facilitated, the potential safety hazard of upward waves is effectively reduced and even avoided, the installation and use of the test equipment are greatly facilitated, and the operation area is maximized.

Description

technical field [0001] The invention relates to the technical field of double-hull or multi-hull ships, in particular to a sea-passing well opening and closing device for a small-water plane double-hull or multi-hull ship and a method for using the same. Background technique [0002] Small water surface two-hull or multi-hull ships are mainly used in scientific investigations, underwater radiated noise measurement, deep-sea equipment testing and other disciplines. Small-surface twin-hull or multi-hull ships are generally equipped with sea-passing wells of different sizes in the connecting bridge area according to their functional requirements. Scientists can hoist sonar equipment, multi-beam, sound velocity meter and other instruments and equipment through the sea-passing well. Investigate device fit. [0003] Setting the opening and closing device at the sea-passing well is a way to prevent the waves from passing through the sea-going well. In the prior art, when arrangin...

Problems solved by technology

[0004] The layout of the existing hatch cover occupies the deck area. In order to prevent the damage caused by the waves, the deck surface also needs a large number of reinforced structures, which increases the weight and raises the center of gravity of the ship. It is especially not suitable for small water double bodies that are sensitive to the weight and center of gravity or multi-hull ships; for small waterplane area double-hull or multi-hull ships, the arrangement of the existing hatch covers not only destroys the integrity of the deck surface, affects the overall appearance, but also increases the cost of equipment installation brackets. The height affects the view of the pilothouse to observe the stern operation area, and when the waves beat heavily, the hoisting device of the sea well can be photographed away from the hull, which has hidden dangers of safety accidents and loss of personnel and property
