[0080] By setting the pressurizing assembly 4 to cooperate with the resistance adding assembly 7, when the pressurizing assembly 4 is launched through the hull 3, the piston block 43 is driven to push the pressure difference generated when the buffer 44 is discharged, and the resistance is increased. When entering the water, the wire rope 6 stretches straight and drives the resistance increasing plate 71 to unfold. After entering the water, the contact area with the water is increased to increase the resistance. First, the hull 3 can be smoothly entered into the water. After entering the water, the resistance increasing component 4 is matched with the increasing component 4 7 Increase the resistance of the hull 3, which is a good restriction to prevent the hull from rushing too far out of the water, so that the hull 3 will not affect the operation of other ships on the water surface, improve safety, and greatly reduce the anchor of the hull 3 when launching. The chain tension pr...

The invention provides an underwater resistance increasing device and method for a large ship. The underwater resistance increasing device comprises a slipway, a ship body which is arranged on the shipway, and two pressurizing assemblies which are fixed to the front face of the slipway and are located at the left side and the right side of the ship body. According to the underwater resistance increasing device and method for the large ship, the pressurizing assemblies are arranged to be matched with a resistance increasing assembly; after the ship enters water, the resistance increasing assemblies are matched with the resistance increasing assembly to increase the resistance of the ship body, the ship body is well prevented from rushing out of the water surface too far, the ship body cannot influence the operation of other ships on the water surface, the security is improved, the anchor chain tension during the launching of the ship body is reduced, the service life of an anchor chainis prolonged, and the ship body is more stabilized after entering the water. The buffer solution is river water or seawater beside the ship construction and the like, and is discharged into the riverwater or seawater during discharging, so that the water recycling is achieved, and the energy conservation and environmental protection are achieved. The resistance increasing plate and the ship bodyare easy and convenient to mount and dismount and can be used repeatedly.
Description
Technical field [0001] The invention relates to the field of auxiliary equipment for launching large ships, in particular to an underwater resistance increasing device and method for large ships. Background technique [0002] Ship, a general term for various ships. Ships are vehicles that can navigate or berth in waters for transportation or operations, and have different technical performance, equipment and structural types according to different usage requirements. [0003] After the ship is built, it needs to be launched into the water. The berth for building the hull is usually set to be slightly inclined. When the hull is launched, it slides into the water through a slide rail and runs out of the anchor to fix it. For large ships, due to the large mass and inertia Large, only use anchors to limit the position. When entering the water, the distance will still be too far out of the water. The too far out distance may affect other ships traveling on the water surface, and there...
