Description

Technical Field

[0001] The present invention relates to the technical field of gyro anti-roll device, and in particular to a hydraulic system and a gyro anti-roll device. Background Art

[0002] Large gyro anti-roll rotors have a large static friction torque during precession due to their heavy rotor weight and large turntable bearing diameter.

[0003] The precession torque M of the gyro anti-roll device at rated speed is cosθ*L*ω (θ is the precession angle, L is the angular momentum, and ω is the angular velocity). As the precession angle θ increases, the precession torque M decreases. In low sea conditions, the ship's swaying amplitude is small and cannot generate enough precession torque to overcome the precession resistance. The gyro rotor cannot precess, and the gyro anti-roll device loses its anti-roll effect. Summary of the invention

[0023] Embodiment 1

[0024] like Figure 1 , Figure 2 As shown, a hydraulic system for a gyro anti-roll device includes a gyro rotor connecting plate 11 for connecting to a gyro rotor, a first accumulator 1, a second accumulator 2, a first proportional reversing valve 3, a second proportional reversing valve 4, a first oil cylinder 5, a second oil cylinder 6, a first non-return valve 7, a second non-return valve 8, a first pressure relief valve 9, and a second pressure relief valve 10. The first accumulator 1 is connected to the first proportional reversing valve 3 through a pipeline; the second accumulator 2 is connected to the second proportional reversing valve 4 through a pipeline; the first proportional reversing valve 3 is respectively connected to the rod chamber (i.e., cylinder head) of the first oil cylinder 5 and the rodless chamber (i.e., cylinder tail) of the second oil cylinder 6 through pipelines; the second proportional reversing valve 4 is respectively connected to the rodless chamber (i.e., cylinder tail) of the first oil cylinder 5 and the rod chamber (i.e., cylinder head) of the second oil cylinder 6 through pipelines; the first oil cylinder 5 is connected to one end of the gyro rotor connecting plate 11, and the second oil cylinder 6 is connected to the other end of the gyro rotor connecting plate 11; the first one-way valve 7 and the first pressure relief valve 9 are respectively connected to the first proportional reversing valve 3; the second one-way valve 8 and the second pressure relief valve 10 are respectively connected to the second proportional reversing valve 4. The hydraulic system forms a pressure difference by cyclically storing energy in the first accumulator 1 and the second accumulator 2, and provides thrust for the precession of the gyro rotor, thereby solving the problems of the large-scale heavy-load gyro anti-roll device failing to precess and having a poor anti-roll effect in low sea conditions, so that the device can play the best anti-roll effect and have a good anti-roll effect in low sea conditions.

[0025] In this embodiment, the hydraulic system further includes a first auxiliary oil cylinder 12 and a second auxiliary oil cylinder 13, each of which is connected to one end of the gyro rotor connecting plate 11, wherein the first auxiliary oil cylinder 12 and the first oil cylinder 5 are relatively arranged on both sides of the gyro rotor connecting plate 11, and the second auxiliary oil cylinder 13 and the second oil cylinder 6 are relatively arranged on both sides of the gyro rotor connecting plate 11. The two auxiliary oil cylinders are used to provide auxiliary power, and the first auxiliary oil cylinder 12 and the second auxiliary oil cylinder 13 respectively assist the first oil cylinder 5 and the second oil cylinder 6 in pushing the gyro rotor, so that the anti-rolling effect is better.

[0026] The principle of this hydraulic system is as follows:

[0027] When the gyro rotor advances clockwise from 0° to 70°, the second proportional reversing valve 4 opens, the pre-pressurized high pressure of the second accumulator 2 releases the pressure, and the oil pressure at the tail of the first cylinder 5 (i.e. the rodless chamber) increases, pushing the piston rod of the first cylinder 5 to move toward the cylinder head (i.e. the rod chamber); at the same time, the oil pressure at the head of the second cylinder 6 (i.e. the rod chamber) increases, pushing the piston rod of the second cylinder 6 to move toward the tail of the cylinder (i.e. the rodless chamber). At this time, the first accumulator 1 is in a pressure storage state.

[0028] When the gyro rotor rotates clockwise to 70°, the first proportional reversing valve 3 opens, the first accumulator 1 starts to release pressure, and the oil pressure at the cylinder head (i.e., the rod chamber) of the first cylinder 5 increases, pushing the piston rod of the first cylinder 5 to move toward the cylinder tail (i.e., the rodless chamber); at the same time, the oil pressure at the cylinder tail (i.e., the rodless chamber) of the second cylinder 6 increases, pushing the piston rod of the second cylinder 6 to move toward the cylinder head (i.e., the rod chamber), and the gyro rotor starts to advance counterclockwise from 70° to 0°, and the second accumulator 2 is in an energy storage state.

[0029] When the gyro rotor rotates counterclockwise from 70° to 0°, the piston rods of the first oil cylinder 5 and the second oil cylinder 6 are both in the middle position of the oil cylinder, and the precession torque M of the gyro anti-roll device is maximum; at the same time, under the action of the rotational inertia of the gyro rotor, the piston rod of the first oil cylinder 5 is driven to continue to move toward the cylinder tail (i.e., the rodless chamber), and the piston rod of the second oil cylinder 6 is driven to continue to move toward the cylinder head (i.e., the rod chamber), and the second accumulator 2 is in a pressure storage state.

[0030] When the gyro rotor rotates counterclockwise to -70°, the second proportional reversing valve 4 opens, the second accumulator 2 begins to release pressure, and the oil pressure at the tail of the first cylinder 5 (i.e., the rodless chamber) increases, pushing the piston rod of the first cylinder 5 to move toward the cylinder head (i.e., the rod chamber); at the same time, the oil pressure at the head of the second cylinder 6 (i.e., the rod chamber) increases, pushing the piston rod of the second cylinder 6 to move toward the tail of the cylinder (i.e., the rodless chamber), and the gyro rotor begins to precess from -70° to 0°, and at this time the first accumulator 1 is in the energy storage state again.

[0031] The two accumulators circulate and store energy to form a pressure difference. When the precession angle θ reaches the maximum, the high-pressure accumulator releases the pressure, and the first oil cylinder 5 and the second oil cylinder 6 provide thrust for the precession of the gyro rotor, ensuring that the gyro rotor can overcome the precession resistance and prevent the gyro rotor from being unable to continue precession due to too small a rotational torque.

[0032] The beneficial effect of this embodiment is that the present invention can solve the problems that a large heavy-load gyro anti-roll device cannot precess and has a poor anti-roll effect in low sea conditions, so that the gyro anti-roll device can also play an optimal anti-roll effect in low sea conditions and has a good anti-roll effect.

[0033] Embodiment 2

[0034] like Figure 1 , Figure 2 As shown, a gyro anti-roll device includes a base, a gyro rotor and the above-mentioned hydraulic system. The gyro rotor is rotatably mounted on the base; the hydraulic system is connected to the gyro rotor; the hydraulic system includes a gyro rotor connecting plate 11, a first accumulator 1, a second accumulator 2, a first proportional reversing valve 3, a second proportional reversing valve 4, a first oil cylinder 5, a second oil cylinder 6, a first non-return valve 7, a second non-return valve 8, a first pressure relief valve 9, and a second pressure relief valve 10. The first accumulator 1 is connected to the first proportional reversing valve 3 through a pipeline; the second accumulator 2 is connected to the second proportional reversing valve 4 through a pipeline; the first proportional reversing valve 3 is respectively connected to the rod chamber (i.e., cylinder head) of the first oil cylinder 5 and the rodless chamber (i.e., cylinder tail) of the second oil cylinder 6 through pipelines; the second proportional reversing valve 4 is respectively connected to the rodless chamber (i.e., cylinder tail) of the first oil cylinder 5 and the rod chamber (i.e., cylinder head) of the second oil cylinder 6 through pipelines; the first oil cylinder 5 is connected to one end of the gyro rotor connecting plate 11, and the second oil cylinder 6 is connected to the other end of the gyro rotor connecting plate 11; the first one-way valve 7 and the first pressure relief valve 9 are respectively connected to the first proportional reversing valve 3; the second one-way valve 8 and the second pressure relief valve 10 are respectively connected to the second proportional reversing valve 4; the gyro rotor connecting plate 11 is connected to the gyro rotor. The device forms a pressure difference by cyclically storing energy in the first accumulator 1 and the second accumulator 2, and provides thrust for the precession of the gyro rotor, thereby solving the problems of the large-scale heavy-load gyro anti-roll device failing to precess and having a poor anti-roll effect in low sea conditions, so that the device can play the best anti-roll effect and have a good anti-roll effect in low sea conditions.

[0035] In this embodiment, the hydraulic system further includes a first auxiliary oil cylinder 12 and a second auxiliary oil cylinder 13, each of which is connected to one end of the gyro rotor connecting plate 11, wherein the first auxiliary oil cylinder 12 and the first oil cylinder 5 are relatively arranged on both sides of the gyro rotor connecting plate 11, and the second auxiliary oil cylinder 13 and the second oil cylinder 6 are relatively arranged on both sides of the gyro rotor connecting plate 11; the four oil cylinders can be installed on the base respectively. The two auxiliary oil cylinders are used to provide auxiliary power, and the first auxiliary oil cylinder 12 and the second auxiliary oil cylinder 13 respectively assist the first oil cylinder 5 and the second oil cylinder 6 in pushing the gyro rotor, so that the anti-roll effect is better.

[0036] The principle of this hydraulic system is as follows:

[0037] When the gyro rotor advances clockwise from 0° to 70°, the second proportional reversing valve 4 opens, the pre-pressurized high pressure of the second accumulator 2 releases the pressure, and the oil pressure at the tail of the first cylinder 5 (i.e. the rodless chamber) increases, pushing the piston rod of the first cylinder 5 to move toward the cylinder head (i.e. the rod chamber); at the same time, the oil pressure at the head of the second cylinder 6 (i.e. the rod chamber) increases, pushing the piston rod of the second cylinder 6 to move toward the tail of the cylinder (i.e. the rodless chamber). At this time, the first accumulator 1 is in a pressure storage state.

[0038] When the gyro rotor rotates clockwise to 70°, the first proportional reversing valve 3 opens, the first accumulator 1 starts to release pressure, and the oil pressure at the cylinder head (i.e., the rod chamber) of the first cylinder 5 increases, pushing the piston rod of the first cylinder 5 to move toward the cylinder tail (i.e., the rodless chamber); at the same time, the oil pressure at the cylinder tail (i.e., the rodless chamber) of the second cylinder 6 increases, pushing the piston rod of the second cylinder 6 to move toward the cylinder head (i.e., the rod chamber), and the gyro rotor starts to advance counterclockwise from 70° to 0°, and the second accumulator 2 is in an energy storage state.

[0039] When the gyro rotor rotates counterclockwise from 70° to 0°, the piston rods of the first oil cylinder 5 and the second oil cylinder 6 are both in the middle position of the oil cylinder, and the precession torque M of the gyro anti-roll device is maximum; at the same time, under the action of the rotational inertia of the gyro rotor, the piston rod of the first oil cylinder 5 is driven to continue to move toward the cylinder tail (i.e., the rodless chamber), and the piston rod of the second oil cylinder 6 is driven to continue to move toward the cylinder head (i.e., the rod chamber), and the second accumulator 2 is in a pressure storage state.

[0040] When the gyro rotor rotates counterclockwise to -70°, the second proportional reversing valve 4 opens, the second accumulator 2 begins to release pressure, and the oil pressure at the tail of the first cylinder 5 (i.e., the rodless chamber) increases, pushing the piston rod of the first cylinder 5 to move toward the cylinder head (i.e., the rod chamber); at the same time, the oil pressure at the head of the second cylinder 6 (i.e., the rod chamber) increases, pushing the piston rod of the second cylinder 6 to move toward the tail of the cylinder (i.e., the rodless chamber), and the gyro rotor begins to precess from -70° to 0°, and at this time the first accumulator 1 is in the energy storage state again.

[0041] The two accumulators circulate and store energy to form a pressure difference. When the precession angle θ reaches the maximum, the high-pressure accumulator releases the pressure, and the first oil cylinder 5 and the second oil cylinder 6 provide thrust for the precession of the gyro rotor, ensuring that the gyro rotor can overcome the precession resistance and prevent the gyro rotor from being unable to continue precession due to too small a rotational torque.

[0042] The beneficial effect of this embodiment is that the present invention can solve the problems that a large heavy-load gyro anti-roll device cannot precess and has a poor anti-roll effect in low sea conditions, so that the gyro anti-roll device can also play an optimal anti-roll effect in low sea conditions and has a good anti-roll effect.

[0043] The above is only a specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any changes, combinations or substitutions that can be easily thought of by any technician familiar with the art within the technical scope disclosed in the present invention should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention shall be based on the protection scope of the claims.
