As shown in fig. 1 and 2, the ship intercepting actuator of the present invention comprises an intercepting plate 1 having an equivalent vertical extension, wherein a fixed end of the intercepting plate 1 is movably connected to an intercepting plate mounting seat 5 through a first pin 4, and the intercepting plate 1 can rotate around the fixed end relative to the intercepting plate mounting seat 5;

the top of the intercepting plate 1 is fixedly connected with a driving seat 7, the length of the driving seat 7 extends along the width direction of the intercepting plate 1, and the end part of the driving seat 7 is movably connected with a second pin shaft 6; a radial distance is formed between the second pin shaft 6 and the first pin shaft 4; the driving seat 7 is movably connected with a piston rod 8 of the hydraulic oil cylinder through a second pin shaft 6, and a cylinder body 9 of the hydraulic oil cylinder is movably connected with a cylinder seat 11 through a third pin shaft 10;

the cylinder block 11 and the cut-off plate mounting seat 5 are fixedly connected with the stern of the ship body 100; preferably, the cylinder block 11 and the cut-off plate mount 5 are arranged in a vertical direction;

the vertical displacement amplitude of the edge A of the lower edge of the intercepting plate 1 can be controlled by controlling the movement stroke of the piston rod 8, so that the vertical distance (namely the intercepting depth) between the edge A of the lower edge of the intercepting plate 1 and the ship bottom plate is adjusted.

As shown in fig. 4, the intercepting plate 1 comprises a top plate 1-1 and side plates 1-2, a fixing part B of the top plate 1-1 is fixedly provided with a plurality of connecting lug seats 1-3 along the length direction, the connecting lug seats 1-3 are provided with shaft holes 1-4, and the shaft holes 1-4 are matched with a first pin shaft 4; the intercepting plate 1 is movably connected with a first pin shaft 4 through a connecting lug seat 1-3; the moving part C of the top plate 1-1 is fixedly connected with the upper edge of the side plate 1-2; the top plate 1-1 and the side plate 1-2 can be integrally formed;

the length of the top plate 1-1 and/or the side plate 1-2 forms the length of the cut-off plate 1, and the length direction of the cut-off plate 1 extends along the width direction of the ship bottom when the cut-off plate is installed;

two ends of the top plate 1-1 and the side plate 1-2 are respectively and fixedly provided with

end covers

2 and 3, so that an inner cavity of the intercepting plate 1 is formed, the inner cavity of the intercepting plate 1 faces to the running front of the ship body, and when the intercepting plate 1 forms a water intercepting depth, water flow can flow into the inner cavity of the intercepting plate 1; the inner wall of the side plate 1-2 is used as the working surface of the cut-off plate 1;

the side plates 1-2 are preferably arc-shaped in cross-section so that a lifting force corresponding to the length of the closure plate 1 can occur at the intersection with the bottom of the stern of the ship when subjected to a water current.

A piston rod 8 of the hydraulic oil cylinder can make telescopic motion within a certain length range; when the piston rod 8 is extended to the longest target length along the cylinder axis, the cutoff plate 1 is in a fully open state, as shown in fig. 2; when the piston rod 8 is retracted to the shortest target length along the cylinder axis, the closure plate 1 is in a retracted state, as shown in fig. 3.

Preferably, the moving part C of the top plate 1-1 is always higher than the fixed part B thereof no matter the intercepting plate 1 is in any state, so that the intercepting plate 1 is in the working state, the force in the horizontal direction only acts on the side plate 1-2 and does not act on the top plate 1-1, thereby forming the optimal choke function; when water flows into the inner cavity of the cut-off plate 1, the water acts on the top plate 1-1 again, so that upward fluid acting force is formed to adjust the posture of the ship.

When in use, the invention is arranged at the stern part of a ship body.

The working principle of the invention is as follows:

in the initial state, the intercepting plate 1 is in the retracted state as shown in fig. 3, and the lower edge a of the intercepting plate 1 is located at the upper position of the bottom plate of the ship, so that the movement of the ship is not influenced;

when the hydraulic cylinder is used, the hydraulic cylinder is driven, the piston rod 8 of the hydraulic cylinder extends out to drive the driving seat 7 to rotate clockwise around the second pin shaft 6, and meanwhile, the cylinder body 9 of the hydraulic cylinder rotates anticlockwise around the third pin shaft 10 relative to the cylinder seat 11; because the driving seat 7 is fixedly connected with the intercepting plate 1, the driving seat 7 drives the intercepting plate 1 to synchronously move while rotating, so that the intercepting plate 1 rotates clockwise around the first pin shaft 4 relative to the ship body 100, and the vertical displacement of the edge A of the lower edge of the intercepting plate 1 is realized; at this time, the water flow can flow into the inner cavity of the cutoff plate 1, thereby generating an upward lift force to the cutoff plate 1 to adjust the posture of the ship.

According to the invention, the intercepting plate 1 is driven to vertically turn around the fixed axis of the intercepting plate through the hydraulic oil cylinder, so that the intercepting depth of the intercepting plate 1 is adjusted, different intercepting depths of the intercepting plate 1 generate different lifting forces and thrust forces, and thus additional pitching moment is generated, and finally the navigation attitude is controlled.

The control mechanism of the invention to the navigation attitude is as follows: when the cut-off plate 1 is turned downwards and keeps a certain cut-off depth, water flow can flow into the inner cavity of the cut-off plate 1, so that the water flow flowing through the vicinity of the lower surface of the stern is subjected to the flow blocking effect of the cut-off plate 1, and simultaneously, a lifting force corresponding to the extending length of the cut-off plate 1 is generated at the bottom of the stern, so that an additional pitching moment is generated, and the sailing posture is adjusted.

One set of actuating mechanism can be respectively arranged on the port and the starboard of the stern part of the ship body; the extending lengths of the actuating mechanisms positioned at the two sides of the ship body can be consistent or inconsistent; when the extension lengths of the intercepting plates 1 on the two sides of the ship body are consistent, the pitching and the heaving of the ship body can be inhibited; when the lengths of the cut-off plates 1 on both sides of the hull are not uniform, the rolling of the hull can be suppressed.

According to the invention, the intervention on the stern water flow of the ship body is implemented by adjusting the intercepting depth of the intercepting plate 1, so that the navigation attitude and the motion response of the ship are adjusted. When the cut-off plate 1 is put down, water flow can be cut off, a large-area high-pressure area is formed in the peripheral area of the ship bottom, so that a certain hydrodynamic lift force is generated, a pitching moment is induced to be generated, the resistance of the ship in the sailing process is reduced, and the sailing speed is improved.

It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the spirit or scope of the invention. Thus, it is intended that the present invention cover the modifications and variations of this invention provided they come within the scope of the appended claims and their equivalents.
