Problems solved by technology
[0003] When the speed of the ship is too fast, the hull can only rely on the reverse thrust of the propeller, and the process takes too long to achieve the purpose of quickly reducing the speed or stopping the ship.
[0004] And patent No. CN 211543798 U discloses a kind of ship automatic power acceleration device, adopts the lower end of lift plate to be connected with shell by a plurality of movable hinges in this device, and the horizontal plane of shell and hull is obliquely fixed, makes lift plate and The horizontal plane is a fixed 30-degree inclined structure, and the lift coefficient of this structure will be less than the tangent function of the horizontal angle when the speed is low, and there may be adverse factors that may cause resistance

A self-powered controllable accelerating device for a ship comprises side wing devices and a bottom device. The side wing devices are installed on the two sides of a ship body, each side wing device comprises a side wing shell, and the side wing shells are connected with side wing lifting force plates through two multi-stage hydraulic telescopic supporting rods; the center of the side face of the side wing lifting force plate is connected with the side wing shell through a center ball joint, and the two ends of the multi-stage hydraulic telescopic supporting rod are connected with the side wing shell and the side wing lifting force plate through supporting rod ball joints respectively. The bottom device is installed at the bottom of the ship body and comprises a bottom shell, and the bottom shell is connected with a bottom lifting plate through two bottom front hydraulic telescopic supporting rods and two bottom multi-stage hydraulic telescopic supporting rods. The two ends of the bottom front hydraulic telescopic supporting rod and the two ends of the bottom multi-stage hydraulic telescopic supporting rod are connected with the bottom lifting plate and the bottom shell correspondingly through bottom hinges. The device can improve the running speed of the ship or quickly reduce the running speed of the ship, so that the ship is braked and is in a safe state.
Description
technical field [0001] The invention relates to an automatic power controllable acceleration device for ships. Background technique [0002] Because the ship will be subjected to the effect of resistance when traveling in water, it is difficult to greatly increase the speed of the ship. When the ship sails at a low speed, the frictional resistance dominates; when the ship sails at a high speed, the wave-making resistance increases rapidly and exceeds the frictional resistance to dominate. To increase the speed of the ship, one is to increase the power of the ship, and the other is to reduce water resistance. [0003] When the speed of the ship is too fast, the hull can only rely on the reverse thrust of the propeller, and the process takes too long, and the purpose of quickly reducing the speed or stopping the ship cannot be achieved in an unexpected situation. [0004] And patent No. CN 211543798 U discloses a kind of ship automatic power acceleration device, adopts the l...
