Description

Technical Field

[0001] The invention relates to an intelligent hatch corner unloading plate for a bulk carrier and a working method thereof, and belongs to the technical field of ship design. Background Art

[0002] Bulk carriers usually transport coal, grain, salt, ore, cement, steel coils and other cargoes. Since coal, grain, salt and other similar bulk cargoes tend to accumulate on the platform at the corner of the hatch in the cargo hold during loading and unloading, they cannot flow out during unloading. In this case, some special unloading equipment and methods, such as vibrators, may be required. The use of these equipment may also cause additional vibration and impact to the structure of the hatch corner, affecting its stability and integrity. Summary of the invention

[0003] In order to solve the problems existing in the prior art, the present invention provides a bulk carrier intelligent hatch corner unloading plate and a working method. The unloading plate has the advantage of controllable retraction and extension, and is implemented by means of a controller, a motor system, and an electromagnetic coil.

[0004] The technical solution adopted by the present invention is: an intelligent hatch corner unloading board for bulk carriers, which comprises a first unloading board and a second unloading board, wherein the first unloading board is arranged on the first hatch coaming through an electric hinge, and the second unloading board is arranged on the second hatch coaming through an electric hinge;

[0005] A first round steel is arranged at the back edge of the first unloading plate, and a first electromagnetic coil is arranged on the outer side of the first round steel; a second round steel is arranged at the back edge of the second unloading plate, and a second electromagnetic coil is arranged on the outer side of the second round steel;

[0006] The unloading plate also includes a control unit, a solar module and a position sensor. The control unit is electrically connected to the motor system, the first electromagnetic coil, the second electromagnetic coil and the position sensor. The motor system is electrically connected to the electric hinge. The control unit controls the motor system to work, and the motor system drives the electric hinge to work, so that the first unloading plate and the second unloading plate are closed or opened. The control unit controls the current direction of the first electromagnetic coil and the second electromagnetic coil respectively, thereby controlling the magnetic force of the first electromagnetic coil and the second electromagnetic coil to attract or repel each other. The solar module is electrically connected to the control unit and the motor system, and provides electrical energy.

[0007] The closed state of the first unloading board and the second unloading board is: the sides of the first unloading board and the second unloading board are in contact, and the first unloading board and the second unloading board block the corner of the hatch;

[0008] The first unloading board and the second unloading board are in an open state: the first unloading board is attached to the first hatch coaming, and the second unloading board is attached to the second hatch coaming.

[0009] A working method of an intelligent hatch corner unloading plate for a bulk carrier:

[0010] When the ship is loaded with solid cargo in fixed or packaged form, the first unloading board and the second unloading board are opened, the first unloading board is attached to the first hatch coaming, and the second unloading board is attached to the second hatch coaming;

[0011] When the opening button of the control unit is pressed, the control unit transmits the command to the motor system, and the motor system drives the first unloading plate and the second unloading plate to rotate around the electric hinge; at the same time, the first electromagnetic coil and the second electromagnetic coil are energized, and the first unloading plate and the second unloading plate form the same magnetic poles, repelling each other, and also causing the first unloading plate and the second unloading plate to rotate upward, and when the first unloading plate is attached to the first hatch coaming and the second unloading plate is attached to the second hatch coaming, the position sensor senses the position of the first unloading plate and the second unloading plate, and feeds back the signal to the control unit, and the control unit controls the motor system to stop working; the first electromagnetic coil and the second electromagnetic coil remain energized to generate magnetic force, respectively causing the first unloading plate to be adsorbed to the first hatch coaming and the second unloading plate to be adsorbed to the second hatch coaming;

[0012] When the ship is loading bulk cargo, the first unloading board and the second unloading board need to be lowered;

[0013] Press the closing button of the control unit, and the first electromagnetic coil and the second electromagnetic coil are powered off. The motor system works to drive the first unloading plate and the second unloading plate to rotate around the electric hinge until the first unloading plate and the second unloading plate intersect with the deck. The position sensor feeds back a signal to the control unit, and the control unit controls the motor system to stop working.

[0014] The first electromagnetic coil and the second electromagnetic coil are energized, and the first electromagnetic coil and the second electromagnetic coil on the first unloading plate and the second unloading plate form opposite magnetic poles and attract each other, ensuring that the first unloading plate and the second unloading plate are in a tightly closed state.

[0015] The bulk cargoes include coal, grains, salt, ore, cement, etc., and the shaped or packaged cargoes include steel coils, bundles or boxes of cargo, etc.

[0026] Unless otherwise specifically stated, the relative arrangement of the parts and steps described in these embodiments, the numerical expressions and numerical values ​​do not limit the scope of the present invention. At the same time, it should be clear that, for ease of description, the sizes of the various parts shown in the drawings are not drawn according to the actual proportional relationship. The technology, methods and equipment known to ordinary technicians in the relevant field may not be discussed in detail, but in appropriate cases, the technology, methods and equipment should be regarded as part of the authorization specification. In all examples shown and discussed here, any specific value should be interpreted as merely exemplary, rather than as a limitation. Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar numbers and letters represent similar items in the following drawings, so once an item is defined in one drawing, it does not need to be further discussed in subsequent drawings.

[0027] In the description of the present invention, it is necessary to understand that the directions or positional relationships indicated by directional words such as "front, back, up, down, left, right", "lateral, vertical, perpendicular, horizontal" and "top, bottom" are usually based on the directions or positional relationships shown in the drawings. They are only for the convenience of describing the present invention and simplifying the description. Unless otherwise specified, these directional words do not indicate or imply that the device or element referred to must have a specific direction or be constructed and operated in a specific direction.
