Description

Technical Field

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

[0002] Rudder angle refers to the angle between the plane of the rudder blade and the bow and stern lines of the ship when the rudder blade of a ship or other watercraft rotates around its axis of rotation. It is a key parameter for measuring the degree of rudder blade deflection and directly affects the ship's steering performance, navigation stability and maneuvering safety. Therefore, rudder angle testing is an important part of ship manufacturing, maintenance and daily operation.

[0003] Currently, traditional rudder angle testing devices typically have a fixed height, making it difficult to adjust them according to the testing requirements of different rudder body specifications. This limits their applicability and makes it difficult to meet diverse testing scenarios. On the other hand, the angle detection method is singular, relying heavily on manual reading of the corresponding values ​​of the pointer and the dial, which is cumbersome and prone to human error affecting the detection accuracy. Therefore, we propose a rudder angle testing device to solve the above problems. Utility Model Content

[0008] Preferably, the bottom surfaces of both support covers are fixedly connected to mounting base plates, and mounting holes are provided on one side of each of the two mounting base plates.

[0009] Preferably, a bearing is fixedly embedded in the bottom surface of the supporting top plate, and the inner ring of the bearing is fixedly connected to the outer surface of the drive shaft.

[0011] Preferably, a controller is fixedly installed on one side of one of the lifting support components, and the controller is electrically connected to the electric push rod, the drive component and the angle sensor respectively through wires.

[0012] Compared with the prior art, the beneficial effects of this utility model include: by setting two lifting support components, the lifting support plate can be driven to slide flexibly within the support cover, thereby realizing the adjustment of the height of the support top plate, which solves the problem that the height of the traditional device is fixed and cannot adapt to the testing needs of different specifications of rudder bodies. In addition, by driving the drive shaft, connecting seat and rudder angle plate to rotate through the drive component, and the mechanical cooperation between the pointer plate and the scale, an intuitive angle reference can be provided, which is convenient for operators to observe in real time. At the same time, the angle sensor can transmit the detection data to the controller in real time to realize digital recording. Through the dual design of mechanical display and electronic detection, the intuitiveness of traditional pointer reading is retained, and the error of manual reading is eliminated by sensor data, thereby improving the accuracy of rudder angle testing.

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

[0022] A rudder angle testing device includes a supporting top plate 1, a mounting plate 2 fixedly mounted on the upper surface of the supporting top plate 1, a driving component 3 fixedly mounted on the upper surface of the mounting plate 2, a driving shaft 12 fixedly mounted on the output end of the driving component 3, a connecting seat 13 fixedly mounted on one end of the driving shaft 12, and an angle sensor 4 fixedly mounted on the inner wall of the connecting seat 13. The driving component 3 is mostly a servo motor, containing a stator and a rotor. When energized, the stator generates a rotating magnetic field, driving the rotor to rotate. Torque is output through the driving shaft 12, which can precisely control the speed and direction, providing stable power for the device. The angle sensor 4 has a built-in rotating shaft and an encoder disk. When the shaft rotates with the rudder angle plate 5, the encoder disk cuts light or changes the electromagnetic signal, thus transmitting the signal. The angle sensor 4 is converted into an angle electrical signal through a circuit to achieve accurate angle detection. One end of the angle sensor 4 is fixedly mounted with a rudder plate 5, and a pointer plate 6 is fixedly connected to one side of the rudder plate 5. A scale 7 is provided above the pointer plate 6. Two lifting support components 9 are provided below the support top plate 1. The mounting plate 2 is used to fix the drive component 3 to ensure its stable operation. The drive component 3 is a power source that transmits power through the drive shaft 12 at the output end. The connecting seat 13 serves to connect the drive shaft 12 and the angle sensor 4. The angle sensor 4 is responsible for detecting the rotation angle of the rudder plate 5. The rudder plate 5 is the core component that simulates the deflection of the rudder blade. The pointer plate 6 on its side and the scale 7 above it work together to achieve a direct display of the angle.

[0023] In this embodiment, both lifting support members 9 include a support cover 901. Lifting support plates 902 are slidably connected to the inner walls of both support covers 901. The upper surfaces of both lifting support plates 902 are fixedly connected to the bottom surface of the supporting top plate 1. A connecting groove 903 is provided on the bottom surface of both lifting support plates 902. Electric push rods 904 are fixedly installed on the inner bottom walls of both support covers 901. In this application, the two electric push rods 904 adopt the same model and specification, and are synchronously controlled by a controller 15. The controller 15 can control the two electric push rods. The power supply parameters of the push rod 904, such as voltage and current, are uniformly regulated to ensure that its extension rate and extension amount are consistent, thereby achieving precise synchronous operation. The extension ends of the two electric push rods 904 are fixedly installed on the inner walls of the two connecting slots 903 respectively. The support cover 901 can provide a sliding track for the lifting support plate 902 to ensure the stability of the lifting process. The electric push rod 904 on the inner bottom wall of the support cover 901 is the driving component, which drives the lifting support plate 902 to move up and down through extension and retraction, thereby realizing the height adjustment of the support top plate 1.

[0024] In this embodiment, mounting base plates 11 are fixedly connected to the bottom surfaces of both support covers 901. Mounting holes 10 are opened on one side of each of the two mounting base plates 11. Bearings 14 are fixedly embedded in the bottom surface of the support top plate 1. The inner ring of the bearing 14 is fixedly connected to the outer surface of the drive shaft 12. Two fixing plates 8 are fixedly connected to one side of the support top plate 1. One side of each of the two fixing plates 8 is fixedly connected to one side of the dial 7. A controller 15 is fixedly installed on one side of a lifting support 9. The controller 15 is electrically connected to the electric push rod 904, the drive component 3, and the angle sensor 4 through wires. The mounting base plates 11 and mounting holes 10 are used to fix the device on the workbench to enhance overall stability. The bearing 14 on the bottom surface of the support top plate 1 cooperates with the drive shaft 12 to reduce friction when the drive shaft 12 rotates and ensure its smooth operation. The two fixing plates 8 are used to fix the dial 7 to ensure the accuracy of the angle display. The controller 15 is used to realize centralized control of each component, and the device can be operated to complete height adjustment and angle testing.

[0025] Working principle: When the height of the support top plate 1 needs to be adjusted to adapt to different test requirements, the controller 15 sends a signal to the electric push rod 904 in the two lifting support components 9. When the electric push rod 904 extends or retracts, it can drive the lifting support plate 902 to slide on the inner wall of the support cover 901, thereby changing the height of the support top plate 1. Then, the controller 15 sends a control signal to the drive component 3. After the drive component 3 starts, it drives the drive shaft 12 to rotate, which can make the connecting seat 13, angle sensor 4 and rudder plate 5 rotate. When the rudder plate 5 rotates, the pointer plate 6 on its side moves synchronously above the scale 7, which can provide an angle reference for the pointer plate 6. At the same time, the angle sensor 4 detects the rotation angle of the rudder plate 5 in real time and transmits the data to the controller 15 through the wire to realize the detection and recording of the angle.

[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.
