Description

Technical Field

[0001] The utility model belongs to the technical field of ship auxiliary equipment, and in particular relates to a gyro with an energy recovery device. Background Art

[0002] Ships experience turbulence during navigation, affecting maneuverability and the passenger experience. Especially in strong winds and waves, the hull can tilt significantly, impacting property and personal safety. Gyroscopic stabilizers are increasingly used in ship roll stabilization due to their advantages, such as being independent of ship speed, compact structure, and minimal space requirements.

[0003] A heavy-duty flywheel is installed inside a gyro. The high-speed rotation of the flywheel generates momentum and a gyroscopic precession effect. The ship's rolling motion generates a precession torque in the rotating flywheel, pushing the flywheel and flywheel frame to precess. Simultaneously, the precession of the rotating flywheel generates a stabilizing torque, which is transmitted to the ship through the flywheel frame and base, suppressing the ship's rolling. Most gyro precession angles range from -60° to +60°. As the ship rolls, the flywheel and flywheel frame precess. A torque application device controls the precession angular velocity of the flywheel and also serves to limit the precession angular range, preventing impacts caused by uncontrolled precession and equipment damage caused by precession beyond the specified range.

[0004] The flywheel has energy storage properties, but the existing anti-roll gyro does not recover the kinetic energy stored in the flywheel, resulting in energy waste. Utility Model Content

[0005] In order to solve the problems raised in the above background technology, the utility model provides a gyro with an energy recovery device, which realizes the integrated arrangement of the flywheel and the axial flux motor, and has a smaller overall volume while ensuring transmission efficiency and effective energy recovery.

[0009] Preferably, the torque application device further includes an externally driven motor and a speed reducer connected to the externally driven motor. The transmission rod moves linearly and is rotationally connected to the precession shaft of the flywheel frame. The speed reducer drives the transmission rod to move linearly, and the transmission rod drives the precession shaft of the flywheel frame to rotate.

[0020] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0021] Combined with Figure 1 and Figure 2 as shown, the present utility model provides the following technical solutions: A gyroscopic stabilizer with an energy recovery device, including a base 1, a flywheel frame 2 rotatably connected to the base 1, a drive motor 3, a flywheel 4, and a PCB board generator 5 disposed in the flywheel frame 2, and a torque application device 6 for applying a braking torque to the flywheel frame 2. By utilizing the gyroscopic torque generated when the rotating heavy flywheel precesses, while suppressing the hull sway, the kinetic energy of the flywheel 4 during rotation is recovered as electrical energy through the PCB board generator 5 coaxially connected to the flywheel 4, realizing the recovery and utilization of energy.

[0022] The flywheel frame 2 is rotatably connected to the base 1 along the transverse direction of the flywheel frame 2 (i.e., the direction where the X-axis is located in the figure). A precession shaft 61 is provided at one transverse end of the flywheel frame 2, and a rotating shaft 62 is provided at the other transverse end of the flywheel frame 2. The flywheel frame 2 is rotatably connected to the base 1 through the precession shaft 61 and the rotating shaft 62.

[0023] During the high-speed rotation of the flywheel 4, it will be affected by air resistance, resulting in energy loss. Therefore, the inside of the flywheel frame 2 is preferably a vacuum to reduce energy loss. To improve the vacuum degree inside the flywheel frame 2, the lower housing 21 and the upper housing 22 forming the flywheel frame 2 are hermetically connected, including setting grooves and embedding sealing rings, and caulking is performed outside the connection to strengthen the seal; wire terminals for wire input / output are provided at both ends of the flywheel frame 2. The wire terminals adopt aviation connectors, and wire end caps are provided to strengthen the seal.

[0024] The output end of the torque application device 6 is connected to the precession shaft 61. For example, a transmission rod (not labeled) is provided at the output end of the torque application device 6, and the transmission rod drives the precession shaft 61 of the flywheel frame 2 to rotate, so as to adjust the angular momentum of the flywheel frame 2, and thus adjust the precession torque of the flywheel 4.

[0025] In one embodiment, the torque application device 6 further includes an external drive motor and a speed reducer connected to the external drive motor. The transmission rod moves linearly and is rotationally connected to the precession shaft 61 of the flywheel frame. The speed reducer drives the transmission rod to move linearly, and the transmission rod drives the precession shaft of the flywheel frame to rotate.

[0026] The drive motor 3, the flywheel 4, and the PCB generator 5 are coaxially arranged in the flywheel frame 2 along the longitudinal direction of the flywheel frame 2 (i.e., the direction where the Y axis is located in the figure). The drive motor 3 is connected to the input end of the flywheel 4, and the PCB board generator 5 is connected to the output end of the flywheel 4.

[0027] The stator of the PCB board generator 5 includes a PCB board 51 and coil windings (not shown) evenly embedded in the PCB board. The rotor of the PCB board generator 5 is of a disc structure and is internally provided with permanent magnets (not shown). Among them, a single-layer or multi-layer coil winding can be embedded in the PCB board 51. The PCB board generator has the advantages of small size, high torque, and light weight, and can better realize the integrated arrangement with the flywheel in the flywheel frame, and has a smaller overall volume on the premise of ensuring the transmission efficiency and effective energy recovery.

[0028] In one embodiment, the drive motor 3 can also be a PCB board motor. The stator of the PCB board motor includes a PCB board and coil windings evenly embedded in the PCB board. The rotor of the PCB board motor is also of a disc structure and is internally provided with permanent magnets. The working principle of the PCB board motor is that after the coils in the stator are energized, a magnetic field is generated, which interacts with the permanent magnets on the rotor to generate a rotational torque, thereby driving the rotor to rotate. Applied to the anti-rolling gyroscope in this embodiment, the flywheel 4 is driven to rotate by the PCB board motor.

[0029] The working principle of the PCB board generator 5 is that through the rotation of the rotor, the coils are made to cut the magnetic force lines, thereby generating an induced electromotive force, which is led out through the terminal and connected in a circuit to generate current. The PCB board generator 5 is connected to the output end of the flywheel 4, and converts the kinetic energy stored in the flywheel 4 into electrical energy for recovery.

[0030] In one embodiment, a flywheel 4 with a weight of 50 kg is used for energy storage, a drive motor 3 with a power of 2.2 kw is used for driving, and a PCB board generator 5 with a power of 5 kw is used for electrical energy recovery.

[0031] Further, for the anti-rolling gyro configuration control module (not shown) provided in this embodiment, the control module is electrically connected to the torque application device 6, the drive motor 3, and the PCB board generator 5. In one embodiment, the control module includes functional modules such as a controller main body, a wireless connection module, a switch module, a speed regulation module, a motor drive module, a power supply module, and an abnormality indication module.

[0032] When the device is working and there is a need to balance the swing, the staff can connect to the control module through the wireless connection module to control it, turn on the device through the switch module to work, and supply power to the device through the power supply module. At this time, the working signal is sent to the motor drive module and the torque application device 6 works. At the same time, the drive motor 2 drives the flywheel 4 to rotate, and the speed of the flywheel 3 can be increased or decreased through the speed regulation module to improve the effect of the device controlling balance. When a module fails and cannot work, the abnormality indication module prompts the staff; when the wireless connection signal is unstable or there is a problem with signal transmission, the wireless signal indication module reminds the staff so as to observe the device situation in time. In addition, a horizontal sensor can be set to monitor the state of the installation carrier in real time to ensure the timeliness of the device working.

[0033] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
