Description

Technical Field

[0001] This utility model relates to the technical field of marine instruments, specifically to a three-sided rudder angle indicator. Background Technology

[0002] A rudder angle indicator is an instrument used to indicate the direction and angle of rotation of the rudder blades when a ship is sailing. Existing rudder angle indicators mainly use a synchro as the main control component, which displays the current actual rudder angle by controlling the rotation of a pointer.

[0003] Three-sided rudder angle indicators are generally installed on larger ships, but it is difficult to fix the installation height of the rudder angle indicator. It is also difficult to adjust the height of the indicator according to the needs of use. The indicator is required to display from 45° to the left and 45° to the right. When traditional rudder angle indicators convert analog values ​​into mechanical angles, the relationship between the two is not completely linear, so there is a problem of display asymmetry. Summary of the Invention

[0021] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0022] like Figures 1 to 5 As shown, the three-sided rudder angle indicator includes a positioning disk 1, an arc-shaped light column display panel 8, and a double-sided LED screen 11. A display tray 7 is located directly below the positioning disk 1, and a display mechanism 9 is connected to the outside of the display tray 7. The display mechanism 9 displays the arc-shaped light column display panel 8 and the double-sided LED screen 11 in multiple directions according to the usage requirements, thereby improving the convenience of rudder angle observation. A positioning mechanism 6 is located directly below the positioning disk 1, and the positioning mechanism 6 adjusts the installation height of the arc-shaped light column display panel 8 and the double-sided LED screen 11 according to the height of the ship's bridge.

[0023] In this embodiment, the positioning mechanism 6 includes a fastening hole 2, a wire positioning groove 3, an internal thread tube 4, an external thread tube 5, a display tray 7, and a wire threading hole 16. The fastening hole 2 is annularly formed on the outer side of the positioning disk 1. The top of the positioning disk 1 has a wire positioning groove 3. The bottom of the positioning disk 1 is connected to the internal thread tube 4. The internal thread tube 4 is connected to the external thread tube 5. The display tray 7 is connected directly below the external thread tube 5. The top of the positioning disk 1 has a through wire threading hole 16. The wire positioning groove 3 is used to wrap and position the battery cell, preventing the device from squeezing the wire and causing damage to the device.

[0024] In this embodiment, the display tray 7 is internally connected to the internal threaded tube 4 via the external threaded tube 5 at the top. The external threaded tube 5 and the internal threaded tube 4 can be rotated and adjusted to meet the installation requirements of the device under different conditions.

[0025] In this embodiment, the display mechanism 9 includes an arc-shaped light column display panel 8, an outer bracket 10, a double-sided LED screen 11, an instrument support 12, an outer shielding plate 13, a rudder angle signal receiving and processing board 14, and fasteners 15. The arc-shaped light column display panel 8 is installed inside the display tray 7. The outer bracket 10 is arranged directly below the display tray 7. The double-sided LED screen 11 is connected to the outer side of the outer bracket 10. The instrument support 12 is arranged inside the display tray 7. The rudder angle signal receiving and processing board 14 is connected to the outer side of the instrument support 12. The outer shielding plate 13 is attached to the top of the instrument support 12.

[0026] In this embodiment, the instrument support 12 is connected to the input terminal of the double-sided LED screen 11 via the rudder angle signal receiving and processing board 14 set on the outside. The connecting rod on the rudder angle transmitter also rotates at the same angle as the actual rudder angle, driving the internal sampling potentiometer to rotate, thereby outputting different voltage values ​​(analog signals). The rudder angle signal receiving and processing board 14 then calculates the actual rudder angle value from the voltage value and outputs it through the digital communication port.

[0027] In this embodiment, the outer bracket 10 is connected to the outside of the double-sided LED screen 11 by a fastener 15 provided on one side, and the fastener 15 is used to laterally position one side of the double-sided LED screen 11 and the outer bracket 10.

[0028] In practical applications, this three-sided rudder angle indicator includes the following functions:

[0029] Step 1: The operator first installs the power connection wire inside the online positioning slot 3, then inserts the wire into the wire hole 16, and then inserts it into the internal thread tube 4 and the external thread tube 5 in sequence. Then, the operator provides power to the rudder angle signal receiving and processing board 14 and the double-sided LED screen 11 below it, and installs the double-sided LED screen 11 on the outside of the outer bracket 10. The double-sided LED screen 11 is then fastened to the outer bracket 10 using fasteners 15.

[0030] Step 2: The operator then inserts the screw into the fastening hole 2 and fastens the positioning plate 1 and the interior of the ship's bridge with the screw, thereby completing the positioning of the positioning plate 1 and the internal thread tube 4. When the power is not on, the operator can adjust the height of the external thread tube 5 and the arc-shaped light column display plate 8 by rotating the display tray 7 and the external thread tube 5 set at the top inside the internal thread tube 4 according to the height of the ship's bridge.

[0031] Step 3: The information from the indicator comes from the information transmitter. The information from the information transmitter is synchronized with the angle of the rudder rotation. The information transmitter transmits the agreed information via twisted pair using the 485 communication method. After the rudder angle signal receiving and processing board 14 receives the data, it is displayed through the arc-shaped light column display board 8 and the double-sided LED screen 11. The power supply is a 24-volt DC power supply that is transformed into 5 volts and 3.3 volts by DC-DC conversion. After the power is turned on and the information is read.

[0032] Therefore, the above-disclosed embodiments are merely illustrative in all respects and are not the only ones. All modifications within the scope of this utility model or its equivalents are included in this utility model.
