Description

Technical Field

[0001] This invention relates to the field of gyroscope anti-roll device systems, and more specifically to a self-generating internal cooling system for a gyroscope anti-roll device. Background Technology

[0002] The anti-roll effect of a gyroscope is positively correlated with the angular momentum of the gyroscope rotor. Given rotor mass limitations, the rotor often needs to maintain a high rotational speed. Furthermore, to reduce the impact of air resistance on the gyroscope rotor's drive power consumption, the gyroscope rotor system is often sealed and evacuated. The rotor's drive motor and bearings are heat-generating components; in a vacuum environment, heat accumulation easily occurs, causing the bearings and motor temperatures to rise, leading to decreased rotor bearing and motor performance and a shortened lifespan. To avoid this, a cooling system is needed to effectively dissipate heat from the gyroscope rotor bearings and motor. The cooling medium is typically a water-based coolant with a high specific heat capacity, using convective heat dissipation for the rotor bearings and motor.

[0003] Because the rotor has a large moment of inertia and low resistance in a vacuum environment, it will continue to run for a considerable period after the gyroscope is shut down. The water pump will also stop supplying water when the gyroscope stops. However, the bearings supporting the rotor will heat up due to the rotor's inertial rotation, leading to a decrease in bearing performance and a shorter lifespan. Premature damage to the rotor bearings will result in frequent maintenance of the gyroscope. To address these issues, a cooling system for the gyroscope anti-roll device needs to be designed to provide cooling even after shutdown, thereby extending the device's lifespan and ensuring normal operation. Summary of the Invention

[0004] To address the aforementioned shortcomings, this invention provides a self-generating internal cooling system for a gyroscope anti-roll device. This system is designed to provide cooling even after shutdown. A cooling system control module controls the electronic water pump and fan to turn on / off, effectively dissipating heat from the gyroscope rotor bearings and motor. The residual kinetic energy of the gyroscope rotor powers the cooling system after a power outage, maintaining its normal operation and effectively preventing damage to related equipment. This extends the lifespan of the anti-roll gyroscope system and ensures normal equipment operation. Therefore, this invention provides the following technical solution:

[0038] Reference Figure 1The cooling system control module 1 is electrically connected to the first temperature sensor 3, the second temperature sensor 4, the electric water pump 5, and the fan 6. The first temperature sensor 3 is located on the outer ring surface of the first bearing 12 of the gyroscope rotor on the side of the motor-generator 11, and the second temperature sensor 4 is located inside the motor-generator 11. The first temperature sensor 3 and the second temperature sensor 4 transmit temperature detection data to the cooling system control module 1, respectively.

The cooling system control module 1 performs signal logic processing and outputs speed regulation signal S1 to control the electric water pump 5 to turn on / off and outputs speed regulation signal S2 to control the fan 6 to turn on / off.

[0039] Working principle: Refer to Figure 2 The first temperature sensor 3 and the second temperature sensor 4 of the water circuit system 2 detect the temperatures of the first bearing 12 of the gyroscope rotor and the motor-generator 11, respectively, and transmit the temperature signals T1 and T2 to the cooling system control module 1.

[0040] When T < T3, the cooling system control module 1 outputs signals S1 and S2 to shut down, including but not limited to, the electric water pump 5 and the fan 6.

The T4 temperature can be set to a suitable temperature that is higher than that of the first bearing 12 of the gyroscope rotor and the motor-generator 11, such as T4 = 60℃.

[0042] When T > T4, the cooling system control module 1 outputs signals S1 and S2, including but not limited to turning on the electric water pump 5 and the fan 6.

The power electronic conversion system 10 puts the motor-generator 11 in the motor state, and drives the gyroscope rotor 7 to accelerate its rotation in the motor state. When the external load needs electrical energy, the power electronic conversion system 10 puts the motor-generator 11 in the generator state, and the gyroscope rotor 7 drives the motor-generator 11 to rotate, converting the mechanical kinetic energy of the gyroscope rotor 7 into electrical energy.

Both the first and second bearing water jackets 201 and 202 transfer heat and cool the first and second bearings 12 and 13. A motor-generator cooling water jacket 203 is mounted on the motor-generator 11 to transfer heat and cool it. A fan 6 is mounted on the side of the water tank 204 to enhance heat dissipation when the cooling system temperature is high. The interior of the water tank 204 has a plate-like structure, which facilitates heat dissipation into the air.

[0046] Working principle: When the anti-roll gyroscope is to start running, the motor-generator 11 is connected to the power supply 8. At the same time, the power electronic conversion system 10 converts the motor-generator 11 into a motor. The motor-generator 11 drives the gyroscope rotor 7 to rotate at high speed. Meanwhile, the power supply 8 supplies power to, but is not limited to, the electronic water pump 5 and the fan 6 through the power conversion and distribution module 9. Then, but is not limited to, the electronic water pump 5 and the fan 6 maintain the normal operation of the cooling water circuit.

[0047] When the anti-roll gyroscope stops, the motor-generator 11 cuts off the power supply 8. At the same time, the power electronic conversion system 10 converts the motor-generator 11 into a generator. The gyroscope rotor 7 drives the motor-generator 11 to generate electricity. The electricity generated by the motor-generator 11 is supplied to, but not limited to, the electronic water pump 5 and the fan 6 via the power conversion and distribution module 9.
