Problems solved by technology

However, the above-mentioned lifting fin device cannot solve the influence of the water flow resistance on the lifting fin when the hull is sailing, and it will cause the lifting fin to vibrate, which will directly cause a large impact on the connection between the lifting fin and the hull. The continuous impact of time will cause damage to the connection parts

Embodiment Construction

[0026] Below in conjunction with accompanying drawing and specific embodiment the present invention is described in further detail;

[0027] Such as figure 1 , 2 , 3, 4, 5, and 6, a scientific investigation ship with a lifting fin system includes a hull 38, and in the hull 38, a shaft 3 extending vertically along the bottom 1 to the cabin 2, the shaft The top of 3 is equipped with a hoisting device 5 for overhauling the lifting fin 4, the hoisting device 5 includes a hydraulic winch 6, a movable pulley 7 and a wire rope 8, and the wire rope 8 is wound on the hydraulic winch 6 and stretched out, passing through the movable pulley 7 and fixed on the Top of Shaft 3.

[0028] The vertical shaft 3 is provided with a lifting fin 4 that is used to carry the detection instrument and extends downward into the water along the vertical shaft 3 and passes through the air bubble layer 9 to reach a predetermined position during detection. The air bubble layer 9 is generated at the bottom ...

Abstract

The invention discloses a scientific research ship with a lifting fin plate system. The ship comprises a ship body, a vertical well is arranged vertically extending to a cabin along a ship bottom in the ship body, and a lifting fin plate used for carrying a detecting instrument is arranged in the vertical well; the two end portions of the lifting fin plate are respectively provided with guide railmechanisms used for helping the lifting fin plate slide and lift, the guide rail mechanisms are vertically laid on the well wall along the arranged direction of the vertical well, and a driving mechanism is arranged on the well wall used for driving the lifting fin plate to descend for detection or to rise and receive ; the scientific research ship further comprises a buffer mechanism used for reducing the impact force generated from a junction of the driving mechanism and the lifting fin plate, when the driving mechanism drives the lifting fin plate to descend at a preset position in water.Due to the buffer mechanism, an oil cylinder is more conveniently connected with the lifting fin plate, when driving the lifting fin plate to descend under water to perform detection, the buffer mechanism can effectively relieve the continuous impact force generated from the water flow resistance to the oil cylinder and the lifting fin plate, when the ship sails.

Description

technical field [0001] The invention relates to the technical field of scientific research ships, in particular to a scientific research ship with a lifting fin system. Background technique [0002] As a mobile laboratory at sea, scientific research ships are key facilities for ocean exploration. At present, some of the marine detection instruments on the marine scientific investigation ship are directly installed on the outer plate of the bottom of the hull, and some are installed on the bottom of the hull or the bottom of the traditional "shaft-rudder" fin instrument cabin. the following requirements; [0003] (1) Measurements can be carried out under a wide range of sea conditions (that is, sea climate conditions) and high ship speeds, so as to shorten the period of measurement tasks and improve the utilization rate of ships and equipment; [0004] (2) The measuring instrument extends as far as possible from the bottom of the ship to avoid the influence of the noise gen...
