Description

Technical Field

[0001] This utility model relates to the field of rudder angle, specifically a rudder angle feedback device. Background Technology

[0002] Rudder angle refers to the angle at which the rudder blade of a ship or other vessel rotates around its axis of rotation. It directly determines the direction and magnitude of the vessel's turn and is a key parameter for navigation and control. Its accurate feedback is crucial for navigation safety and maneuverability.

[0003] Existing rudder angle feedback devices typically use angle detection elements, and potentiometers are one type of angle detection element. However, the contact between the brush and the resistor in the potentiometer is currently unstable, making it susceptible to vibration, which can cause signal fluctuations or even interruptions. In addition, the connection structure with the rudder shaft is complex, installation is time-consuming, and maintenance requires disassembling multiple components, making it difficult to meet the requirements of rapid response control and affecting the control efficiency and safety of the aircraft. To address these issues, we propose a rudder angle feedback device. Utility Model Content

Those skilled in the art can select appropriate circuit components to build the circuit according to the power requirements and control requirements of the equipment. For the power supply components, common general power supply equipment on the market can be used, as long as it meets the voltage and current requirements of the equipment, without special design.

[0021] According to one embodiment of the present invention, in conjunction with the appendix Figure 1-4 As shown.

[0022] A rudder angle feedback device includes a support base 1. A bearing ring 2 is fixedly embedded in one side of the support base 1. A rotating shaft 3 is fixedly connected to the inner ring of the bearing ring 2. A resistor 4 is fixedly installed at one end of the rotating shaft 3. The resistor 4 is a 10kΩ toroidal resistor corresponding to the 0°-360° rotation range of the rudder shaft 7. Each 1° rotation corresponds to a resistance change of approximately 27.78Ω. This linear conversion relationship ensures high accuracy of angle feedback. When the rudder shaft 7 rotates 30°, the resistance value changes by approximately 833.4Ω, corresponding to a voltage change of approximately 0.417V, which can provide accurate numerical data for the control system and effectively improve the accuracy of the rudder shaft 7 angle control. A brush 5 is arranged above the resistor 4. A fixing plate 10 is fixedly connected to one side of the device, and a fixing screw 13 is fixedly connected to the upper surface of the support base 1. The top end of the fixing screw 13 passes through the fixing plate 10 and extends to the top of the fixing plate 10. A connector 6 is fixedly installed at one end of the rotating shaft 3. A rudder shaft 7 is provided on one side of the connector 6. The rotating shaft 3 is flexibly rotated by the bearing ring 2. In addition, the rotating shaft 3 connects the resistor 4 and the connector 6 to realize power transmission. The resistor 4 adopts a 10kΩ ring resistor. By cooperating with the brush 5, the angle change of the rudder shaft 7 is converted into resistance and voltage changes, which can provide accurate basis for the control system. The brush 5 contacts the resistor 4 to realize signal acquisition. The connector 6 and the rudder shaft 7 are the connecting parts between the device and the external rudder system.

[0023] In this embodiment, the connector 6 includes a connector 601. The inner wall of the connector 601 has two threaded holes 602. The inner walls of the two threaded holes 602 are threaded with fixing screws 605. One end of the rudder shaft 7 is provided with a connecting block 603. The outer surface of the connecting block 603 has two threaded grooves 604. The outer surfaces of the two fixing screws 605 are respectively adapted to the inner walls of the two threaded grooves 604. Through the threaded holes 602 of the connector 601, the fixing screws 605, the rudder shaft 7, the connecting block 603 and the threaded grooves 604 can cooperate to achieve a stable and convenient connection between the connector 6 and the rudder shaft 7, which is convenient for installation and maintenance.

[0024] In this embodiment, two positioning holes 11 are provided on the upper surface of the fixing plate 10, and two positioning blocks 12 are fixedly connected to the upper surface of the support base 1. The outer surfaces of the two positioning blocks 12 are respectively in contact with the inner walls of the two positioning holes 11. A locking nut 14 is provided above the fixing screw 13. The inner ring of the locking nut 14 is threadedly connected to the outer surface of the fixing screw 13. A fixing base 8 is fixedly connected to the bottom surface of the support base 1. Two sets of fixing holes 9 are provided on the outer surface of the fixing base 8. One side of the brush component 5 is in contact with the outer surface of the resistor component 4. The positioning holes 11 and the positioning blocks 12 at the support base 1 are used to ensure that the brush component 5 is installed in an accurate position. The fixing screw 13 and the locking nut 14 are used to further fix the fixing plate 10 to ensure that the brush component 5 and the resistor component 4 are in stable contact. The fixing base 8 and the fixing holes 9 are used to fix the entire device in the working position.

[0025] Working principle: When the rudder shaft 7 rotates, it drives the rotating shaft 3 to rotate synchronously through the connecting piece 6. The resistor 4 at one end of the rotating shaft 3 rotates with it. When the rudder shaft 7 rotates, the contact point between the brush 5 and the resistor 4 changes. At this time, the output resistance value will change compared to the initial position. Then, the change in resistance value will cause a corresponding change in the output voltage, thereby converting the angle change of the rudder shaft 7 into a detectable voltage signal. In actual operation, the brush 5 and the resistor 4 always maintain good contact to ensure the stability of signal conversion and can provide feedback on the real-time angle position of the rudder shaft 7, which is convenient for providing reliable angle information to the relevant control system.

[0026] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
