The invention discloses a cultivation work ship with a ship body capable of being opened and closed, and relates to the technical field of cultivation work ships, the cultivation work ship comprises the ship body, a plurality of permeable nettings and a sealing assembly, a containing cavity is formed in the ship body, openings communicated with the containing cavity are formed in the two sides of the ship body, and the multiple permeable nettings divide the containing cavity into a plurality of cultivation areas; the sealing assembly is rotatably mounted to the hull for opening or sealing the opening. The water-permeable netting is arranged to divide the containing cavity into a plurality of culture areas, so that different types of fishes can be cultured, frequent water change between seawater and the plurality of culture areas can be achieved through the opening in the culture mode, the culture effect is guaranteed, automatic water change is achieved through the seawater, and the culture efficiency is improved. The breeding cost is reduced; the opening is sealed by driving the sealing assembly to rotate, so that the integrity of the appearance of the ship body is improved, the sailing resistance can be reduced, and the sailing speed is increased.

A front hydrofoil fixing cover plate is arranged at the top of a front hydrofoil stand column, a front hydrofoil plate is arranged below the front hydrofoil stand column, the front hydrofoil fixing cover plate is fixed to the upper end of the front hydrofoil stand column through a cup head inner hexagonal plug bolt and a hexagonal nut, and a cover is arranged on the outer side of the front hydrofoil fixing cover plate. An electric push rod, a displacement sensor, a displacement sensor mounting frame and a stroke displacement part are arranged in the front hydrofoil fixing cover plate, the displacement sensor is mounted on the displacement sensor mounting frame, the electric push rod is connected with a front hydrofoil ejector rod through the stroke displacement part, and the lower end of the front hydrofoil ejector rod is connected with a front hydrofoil plate through a second clamping plate nut sleeve; the left side of the front hydrofoil stand column is hinged to the front hydrofoil plate through a first clamping plate nut sleeve. The structure design is reasonable, and the angle of the hydrofoil plate can be adjusted, so that the sailing speed and fuel economy are improved, the controllability is improved, and the jolt of a ship body is reduced.

The utility model discloses a ship icebreaking structure relates to ship equipment technical field, and it is set up in the bottom of ship one side to ice, including: mounting panel, be provided with three, and the vertical spacing of adjacent cutting plate increases evenly from both ends to the middle, is used for the icebreaking of ship movement, arc plate is fixed between adjacent cutting plate evenly, and is set to the end of cutting plate and is inclined, the resistance that ice block is received when the ice block of the scheme is reduced significantly, can avoid the ice block between cutting plate and can reduce the additional resistance that the icebreaking of ship forward produces, makes the boat movement more smoothly, when meeting larger ice block, the arc surface of arc plate inclination does not directly have rigid impact with ice block, but through the guiding effect of arc surface, lets larger ice block slide along the direction of inclination, can effectively improve the icebreaking efficiency and navigation speed of ship.
