Description

Technical Field

[0001] This utility model relates to the field of magnetic levitation gyroscope technology, specifically to an active magnetic levitation gyroscope float centering adjustment device. Background Technology

[0002] A gyroscope is a device that uses the angular momentum of a high-speed rotating body to sense the angular motion of its housing relative to inertial space around one or two axes orthogonal to its rotation axis. Other angular motion detection devices that perform the same function using other principles are also called gyroscopes. However, in the use of magnetically levitated gyroscopes, an adjustment mechanism is needed to adjust the center of the float.

[0003] Existing active magnetic levitation gyroscope float centering adjustment devices use a set of displacement sensors to detect the center of the gyroscope float in real time. When a positional shift is detected, the magnetic flux of the magnetic levitation module is changed to alter the magnetic field strength, thereby adjusting the float using magnetic force. However, this method has limitations because the displacement sensors are fixed, resulting in a limited detection range and orientation. This limitation prevents comprehensive detection of the float, leading to low detection accuracy and affecting the adjustment effect. Therefore, there is an urgent need for an active magnetic levitation gyroscope float centering adjustment device to solve these problems. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide an active magnetic levitation gyroscope float centering adjustment device that can comprehensively detect the center of the float, has high detection accuracy, good adjustment effect, and high performance.

[0006] (II) Technical Solution

[0007] This utility model is achieved through the following technical solution: This utility model proposes an active magnetic levitation gyroscope float centering adjustment device, including a housing, a gyroscope installed at the bottom of the housing, a magnetic levitation ball extending from the top center of the gyroscope, a magnetic levitation module fixed at the top of the housing, a pre-reserved insertion hole on the magnetic levitation module, a bearing ring provided on the outer side of the magnetic levitation ball, a protruding ring fixed on the outer wall of the bearing ring, a limit groove opened on the housing at the position corresponding to the protruding ring, a displacement sensor fixed on the inner wall of the bearing ring, a gear ring provided at the bottom of the bearing ring, a gear connected to one side of the gear ring, and a servo motor connected to the gear.

[0008] Furthermore, the gyroscope is fixed inside the housing by screws, and a magnetic shielding layer is provided on the inner wall of the housing.

[0009] By adopting the above technical solution, the magnetic shielding layer can prevent external magnetic fields from affecting the gyroscope, which is used to determine the orientation.

[0010] Furthermore, the socket is electrically connected to the magnetic levitation module, and the magnetic levitation ball is located at the center of the bottom end of the magnetic levitation module.

[0011] By adopting the above technical solution, the socket facilitates the connection of the magnetic levitation module with an external electronic control mechanism. When the position of the magnetic levitation ball is detected to be offset, the magnetic flux of the magnetic levitation module can be controlled to control the magnitude of the magnetic field, change the force on the magnetic levitation ball, and thus adjust it.

[0012] Furthermore, the bearing ring is rotatably connected to the housing, and the displacement sensor is fixed to the inner wall of the bearing ring by screws.

[0013] By adopting the above technical solution, the bearing ring can drive the displacement sensor to rotate around the magnetic levitation ball, thereby enabling the displacement sensor to fully detect the position of the magnetic levitation ball and ensuring the accuracy of the detection.

[0014] Furthermore, the convex ring is welded to the outer wall of the bearing ring, the limiting groove is formed on the inner wall of the housing, the convex ring and the limiting groove are rotatably connected, and both the convex ring and the limiting groove are T-shaped structures.

[0015] By adopting the above technical solution, the combination of the convex ring and the limiting groove not only ensures the rotation performance of the bearing ring, but also provides limiting support for the bearing ring.

[0016] Furthermore, the gear ring is welded to the bottom end of the bearing ring, and the specifications of the gear ring are consistent with those of the bearing ring.

[0017] By adopting the above technical solution, the gear ring can drive the bearing ring to rotate under the action of the gear.

[0018] Furthermore, the gear meshes with the gear ring, and the output shaft of the servo motor is fixedly connected to the gear.

[0019] By adopting the above technical solution, the servo motor can drive the gear to rotate.

[0020] Furthermore, the bottom end of the servo motor is fixedly connected to the inner wall of the housing via a support plate.

[0021] By adopting the above technical solution, it is easy to install and fix the servo motor.

[0022] (III) Beneficial Effects

[0023] Compared with the prior art, this utility model has the following advantages:

[0024] To address the shortcomings of existing active magnetic levitation gyroscope float centering adjustment devices, which rely on a set of displacement sensors to detect the gyroscope float's center in real time and adjust it by changing the magnetic flux of the magnetic levitation module when a position shift is detected, this new invention addresses these issues. The existing devices use a fixed displacement sensor, limiting the detection range and orientation, resulting in low accuracy and incomplete float detection, thus affecting adjustment performance. Instead, this new device incorporates a servo motor, a gear ring, gears, a support ring, and displacement sensors. During real-time position detection of the magnetic levitation ball, the servo motor drives the gear ring via the gears, which in turn drives the displacement sensor around the magnetic levitation ball via the support ring. This allows for comprehensive position detection, ensuring accuracy and enabling rapid adjustment upon detection of displacement, resulting in superior performance. Attached Figure Description

A gyroscope 3 is installed at the bottom of the housing 1 for positioning. A magnetic levitation ball 4 extends from the center of the top of the gyroscope 3. A magnetic levitation module 5 is fixed at the top of the housing 1. The magnetic levitation module 5 has a pre-drilled hole 2 for connecting to an external electrical control mechanism. When a displacement of the magnetic levitation ball 4 is detected, the magnetic flux of the magnetic levitation module 5 can be controlled to control the magnitude of the magnetic field, thereby changing the force on the magnetic levitation ball 4 and adjusting it. A bearing ring 6 is provided on the outside of the magnetic levitation ball 4, and a protruding ring 11 is fixed on the outer wall of the bearing ring 6. The housing 1 and the protruding ring... A limiting groove 12 is provided at the corresponding position of the convex ring 11. The combination of the convex ring 11 and the limiting groove 12 not only ensures the rotation performance of the bearing ring 6, but also provides limiting support for the bearing ring 6. A displacement sensor 10 is fixed on the inner wall of the bearing ring 6. A gear ring 7 is provided at the bottom of the bearing ring 6. A gear 9 is connected to one side of the gear ring 7. A servo motor 8 is connected to the gear 9. During the real-time detection of the position of the magnetic levitation ball 4, the servo motor 8 drives the gear ring 7 to rotate through the gear 9. The gear ring 7 then drives the displacement sensor 10 to rotate around the magnetic levitation ball 4 through the bearing ring 6. This allows the displacement sensor 10 to perform comprehensive detection of the position of the magnetic levitation ball 4, ensuring the accuracy of the detection and enabling rapid adjustment when displacement is detected.

[0032] like Figures 1-3 As shown, in this embodiment, the gyroscope 3 is fixed inside the housing 1 by screws. A magnetic shielding layer is provided on the inner wall of the housing 1. The magnetic shielding layer can prevent the external magnetic field from affecting the gyroscope 3. The socket 2 is electrically connected to the magnetic levitation module 5. The magnetic levitation ball 4 is located at the center of the bottom end of the magnetic levitation module 5. The bearing ring 6 is rotatably connected to the housing 1. The displacement sensor 10 is fixed to the inner wall of the bearing ring 6 by screws. The convex ring 11 is welded to the outer wall of the bearing ring 6. The limiting groove 12 is formed on the inner wall of the housing 1. The convex ring 11 and the limiting groove 12 are rotatably connected. Both the convex ring 11 and the limiting groove 12 are T-shaped structures.

[0033] like Figures 1-3 As shown, in this embodiment, the gear ring 7 is welded to the bottom end of the bearing ring 6. The specifications of the gear ring 7 are consistent with those of the bearing ring 6. The gear 9 meshes with the gear ring 7. The output shaft of the servo motor 8 is fixedly connected to the gear 9. The bottom end of the servo motor 8 is fixedly connected to the inner wall of the housing 1 through the bearing plate.

[0034] The specific implementation process of this embodiment is as follows: In use, the housing 1 is fixed on the corresponding surveying instrument and connected to the external electrical control mechanism through the socket 2. Then, the servo motor 8 drives the gear ring 7 to rotate through the gear 9. The gear ring 7 then drives the displacement sensor 10 to rotate around the magnetic levitation ball 4 through the bearing ring 6. This allows the displacement sensor 10 to fully detect the position of the magnetic levitation ball 4, ensuring the accuracy of the detection. When displacement is detected, the magnetic flux of the magnetic levitation module 5 is controlled to control the magnitude of the magnetic field, changing the force on the magnetic levitation ball 4, and thus adjusting it. The response is rapid and the effect is good.
