The present invention relates to a ship's rudder sensor, and more particularly, to a ship's rudder sensor using a planar magnet that can easily determine the center of a magnet by using a magnet of a hall sensor type rudder sensor as a flat magnet. .

1 is an exemplary view of a steering system of a ship, and FIG. 2 is a diagram schematically illustrating the use of a rudder sensor in the steering system of FIG. 1.

First, referring to FIG. 1, the steering system of a ship includes a steering part 1000 for steering, a steering device 1100 in the form of a cylinder that piston moves by manipulation of the steering part 1000, and the steering device ( 1100) is configured to include a rudder 1200 that is connected to the steering device 1100, the angle of which is adjusted.

Here, a rudder sensor (RUDDER-ANGLE SENSOR) is essentially provided as shown in FIG. 2 to measure the direction angle of the rudder 1200.

Such a rudder sensor has been used as a form of using a variable resistor as disclosed in the Korean Registered Utility Model No. 20-0294521 'Vehicle Direction Key Positioning Device'. There were many problems and short replacement time.

Therefore, recently, the problem of waterproofness has been solved by using a hall sensor type rudder sensor using a magnetic field.

3A is an exemplary view of a conventional hall sensor type rudder sensor, and FIG. 3B is a photograph showing a lower portion of the rudder sensor of FIG. 3A. 3A and 3B, it can be seen that the conventional hall sensor type rudder sensor 1400 uses a cylindrical magnet 1450 like conventional hall sensors.

However, the rudder sensor 1400 using the cylindrical magnet 1450 is not easy to distinguish between the N pole and the S pole of the cylindrical magnet, so it is not easy to find a center point provided between the N pole and the S pole. If the center point is distorted during use, there is a problem in that the operator or the like directly rotates the cylindrical magnet and checks the signal while adjusting the center point, and it is difficult to accurately align the center point.

The present invention is proposed to solve the above problems, and by using a magnet used in a rudder sensor as a flat magnet with a relatively clear distinction between N-pole and S-pole, a flat magnet that can easily determine the center point of the magnet is utilized. The purpose is to provide a ship's rudder sensor.

The rudder sensor of a ship using a flat magnet according to an embodiment of the present invention for solving the above problems includes a sensor housing; One end is inserted into the top of the sensor housing is located inside, the rotating shaft rotates according to the steering of the ship's steering; It may include a planar magnet whose angle is adjusted according to the rotation of the rotating shaft and a detection unit coupled to one side of the sensor housing to detect an angle change of the planar magnet.

Here, the flat magnet is coupled to the rotating shaft, the angle can be adjusted according to the rotation of the rotating shaft.

In addition, the rudder sensor further includes a rotating plate that mediates the connection between the flat magnet and the rotating shaft, wherein the rotating plate protrudes upward from the disk-shaped plate portion and the plate portion, and the rotating shaft is fixed to the center. At a position of a virtual square apex that forms a fixing part, and protrudes in a 'C' shape to form a magnet fixing part to which a flat magnet is fixed on one side of the rotating shaft fixing part, or is formed based on the center of the plate part, It may include a fixed protrusion that protrudes upward in four fan-shaped shapes having a symmetrical structure so that the arc faces outward.

In addition, the rotating plate may further include a tool insert formed in a groove of a 'A' or 'T' cross section at the bottom of the plate portion.

In addition, the rotating plate is further recessed inward from the center of the plate portion, and further includes an insertion groove into which one end of the rotation shaft is inserted, and a fitting protrusion protrudes on one side of the insertion groove, and the rotation shaft has a shape of the fitting protrusion. A corresponding fitting groove is provided, and the rotation shaft can be inserted into the insertion groove so that the fitting protrusion and the fitting groove are aligned with each other.

In addition, the rotating plate further includes a locking protrusion protruding upward so that the locking portion faces outward, and the sensor housing can be provided with a locking groove through which the locking portion can be guided.

The ship's rudder sensor using a planar magnet according to an embodiment of the present invention can easily determine the center point of a magnet by using it as a planar magnet in which the distinction between the N pole and the S pole is relatively clear. There are effects such as reducing the cost and improving the accuracy of the rudder sensor.
