Description

  The present invention relates to a gyro-type wave power generation device using wave energy.

  As gyro-type wave power generation devices using wave energy, those described in Patent Documents 1 and 2 are conventionally known.

  The gyro-type wave power generation device described in Patent Document 1 includes a floating body, a gyro supported by the floating body, and a power generation device connected to a gimbal shaft of the gyro via a speed increasing unit, The number of rotations of the gimbal shaft is controlled so that the swing of the floating body and the rotation of the gyro gimbal are synchronized, and the gyro gimbal is continuously rotated in one direction by the swing of the floating body caused by the waves, and the power generator is driven. Power generation.

  On the other hand, in the gyro wave power generator described in Patent Document 2, similarly to the gyro wave power generator described in Patent Document 1, the floating body, the gyro supported by the floating body, and the gyro of the gyro And a power generation device connected to the gimbal shaft through speed increasing means, and the gyroscope of the gyroscope is rotated by the swinging of the floating body by waves, and the generator is driven to generate power. In order to increase the power generation efficiency, the floating body is a rectangular annular member, and the short side direction or the long side direction of the rectangular annular member is naturally parallel to the wave traveling direction, so that the power generation efficiency is maximized. It can be corrected or held in such a direction.

Japanese Patent No. 4184803 JP 2008-231967 A

  By the way, in the gyro wave power generation device described in Patent Document 1, in order to increase the power generation efficiency, the rotational speed of the gimbal shaft is controlled so that the swing of the floating body and the rotation of the gyro gimbal are synchronized. However, the fluctuation of the floating body is irregular in the wave height, period and direction of the wave with respect to the floating body. It is difficult to synchronously control the rotation of the gimbal with respect to the shaking motion, and there is a problem that requires an expensive control system.

  In addition, it is difficult to completely synchronize, and when a deviation occurs in synchronization, a gyro moment is generated in the direction opposite to the rotational direction of the gimbal shaft, and power generation efficiency is reduced.

  On the other hand, in the gyro wave power generator described in Patent Document 2, a floating body is used as a rectangular annular member so that the gyro wave power generator can be corrected or held in a direction that maximizes the power generation efficiency of the gyro wave power generator. Because the floating body has a large contact area with the sea surface, the floating body is less likely to change its direction with respect to the wave, and the floating body is less likely to be tilted. Has a problem that the power generation capacity is low.

  Here, in Japanese Patent No. 2944495, the energy is such that the input shaft is rotated forward and backward by the movement of a fluid such as a wave, and the rotation of the input shaft in two forward and reverse directions is taken as one direction rotation to the output shaft. An unloader is described. By adopting such an energy extraction device in the gyro wave power generation device described in Patent Document 1, it is considered that the power generation efficiency can be improved.

  However, in the above-described energy extraction device, the number of gears and the amount of meshing of the gears are large, and the inertia weight is large, so that there is a lot of energy loss and power generation efficiency cannot be improved.

  Further, since the input shaft and the output shaft are arranged in parallel, when the power generation device is arranged in the floating body like the gyro wave power generation device described in Patent Document 1, the input shaft and the output shaft are arranged. As a result, the floating body itself is rotated around the rotation axis, and the energy conversion efficiency is lowered.

  An object of the present invention is to provide a low-cost power generation capability gyro wave power generation device that is easy to control without lowering the power generation efficiency against irregular swinging of the floating body.

  In order to solve the above problems, in the present invention, a flywheel having a floating body and a gyro supported by the floating body, the flywheel being rotatable about a horizontally disposed wheel support shaft, and A motor for driving a flywheel, wherein the gimbal moment is generated by the inclination of the wheel support shaft due to waves, and the gimbal shaft arranged orthogonal to the wheel support shaft is rotated in two directions left and right; In a gyro-type wave power generator in which rotation of a shaft is increased by a speed increaser and is input to the generator from the speed increaser to drive the power generator, the gimbal shaft is connected to the first through a one-way clutch. One drive gear and a second drive gear are provided, and a one-way clutch that connects the first drive gear to the gimbal shaft and a second drive gear that connects the gimbal shaft The direction clutch is incorporated in opposite directions with different engagement directions, the rotation of the left and right directions of the gimbal shaft is extracted from the first drive gear and the second drive gear to the output shaft as one direction rotation, and the rotation of the output shaft is A configuration was adopted in which the input to the gearbox was made.

  In the gyro-type wave power generation device having the above-described configuration, the entire device swings due to the wave motion, and the wheel support shaft of the flywheel is centered on the virtual central axis passing through the center of gravity of the flywheel perpendicular to the gimbal axis. When tilting occurs by swinging, a gyro moment is generated by the rotation of the flywheel, and the gimbal shaft rotates. Here, when the imaginary central axis of the entire apparatus swings and the wheel support axis are orthogonal to each other, the gyro moment is maximized.

  The wheel support shaft swings along with the swing of the device due to the vertical movement of the wave, and the direction of the gyro moment also changes when the rotational direction of the tilt changes. Here, when the wheel support shaft that rotates together with the gimbal shaft by the gyro moment does not rotate to the opposite position across the plane including the gimbal shaft and the virtual center axis of the entire apparatus swing, the rotation direction of the gimbal shaft The gimbal shaft rotates in two directions, left and right, as the support shaft swings.

  At this time, the one-way clutch that couples the first drive gear to the gimbal shaft and the one-way clutch that couples the second drive gear to the gimbal shaft are incorporated in opposite directions with different engagement directions. The one-way clutch is engaged by the rotation, and the one-way rotation of the gimbal shaft is transmitted to the one drive gear. Further, the other one-way clutch is engaged by the rotation in the other direction of the gimbal shaft, and the rotation in the other direction of the gimbal shaft is transmitted to the other drive gear.

  The rotation of the first drive gear and the second drive gear is transmitted to the output shaft, and the output shaft rotates continuously in one direction. The rotation is accelerated by the speed increaser and input to the generator. To drive.

  In this way, when the wheel support shaft swings due to the wave, the gimbal shaft rotates in two forward and reverse directions, and the rotation is taken out as one direction rotation of the output shaft, and is increased by the speed increaser to the generator. Since it is input, the generator can be efficiently rotated regardless of the wave period and irregularity, and a gyro wave power generator with a large power generation capacity can be obtained.

  In the gyro wave power generator according to the present invention, when the rotational load of the generator is made variable with respect to the rotational angular displacement and rotational speed of the gimbal shaft, the wheel support shaft is greatly swung by the wave and a large gyro moment is generated. The wheel support shaft that rotates together with the gimbal shaft does not rotate to the opposite position across the plane including the gimbal shaft and the virtual center axis of the entire device swing. As the direction changes, the gimbal shaft can be reliably rotated in two forward and reverse directions.

  Here, when the wheel support shaft is parallel to the virtual central axis of the entire device swinging by the wave, the generation of the gyro moment is eliminated, but the angular position range of the gimbal shaft in the vicinity where the gyro moment is eliminated can be avoided. The generated gyro moment can be increased.

  In addition, a pair of fixedly arranged springs are provided around the gimbal shaft at intervals in the circumferential direction, and a radially extending stopper provided on the gimbal shaft presses the spring to reach the contraction limit. If a rotation angle restricting means that restricts the rotation angle in the left and right directions of the gimbal shaft by elastically deforming it is provided, the wheel support shaft that rotates with the gimbal shaft even if it receives a large gyro moment, It is possible to prevent the rotation of the entire apparatus from rotating across the plane including the virtual central axis to the opposite position by mechanical regulation. As the direction changes, the gimbal shaft can be reliably rotated in two forward and reverse directions. Further, the rotational direction of the gimbal shaft can be smoothly switched by the restoring elasticity of the spring.

  Further, the first drive gear and the second drive gear are bevel gears, the bevel gears are mounted so that their teeth face each other, and a driven bevel gear meshing with each bevel gear is provided at the shaft end portion of the output shaft, thereby simplifying the gear configuration. Therefore, the rotational motion of the gimbal shaft in the forward and reverse directions can be extracted as the rotation of the output shaft in one direction. In addition, since the number of gears is small, the cost can be reduced, and energy loss is small and the power generation efficiency can be improved.

  Here, if a flywheel is provided on the output shaft, fluctuations in rotational force transmitted to the driven bevel gear can be reduced. Further, since the output shaft is rotated by the inertial force of the flywheel, it is possible to smoothly raise the rotational force when the one-way clutch is engaged.

  In the gyro wave power generation device according to the present invention, when the gimbal shaft and the output shaft are arranged in parallel, the entire device is rotated in the same direction as the gimbal shaft and the output shaft, and the rotational force of the rotating shaft of the generator is increased. It becomes low and cannot generate electricity efficiently. In order to suppress a decrease in power generation efficiency, it is preferable to prevent the entire apparatus from being rotated by arranging the gimbal shaft vertically and the output shaft horizontally. In this case, reduction in power generation efficiency can be suppressed, and at the same time, the output shaft, the speed increaser, and the power generator can be arranged horizontally on the gyro, so that maintenance can be facilitated.

  In the gyro wave power generator according to the present invention, as a motor for rotating the flywheel at high speed, an outer rotor type motor in which a rotor is provided on the outside of the stator is adopted, the rotor is fixed to the flywheel, and The stator is supported by a wheel support shaft, and the wheel support shaft is supported by an internal hollow sealed gimbal having a gimbal shaft up and down, so that the flywheel can be freely rotated in the gimbal. The width can be reduced. Further, since the moment of inertia around the gimbal shaft can be reduced, the gimbal shaft can be smoothly rotated by the generated gyro moment.

  In this case, since the rotational resistance of the flywheel can be reduced by reducing the pressure of the internal hollow chamber of the gimbal with a decompressor, the flywheel can also be rotated smoothly. At this time, since heat accumulates in the gyro and the bearing and the motor that rotatably supports the flywheel are easily affected by the heat, it is preferable that the wheel support shaft be cylindrical to enhance the heat dissipation effect.

  In the gyro-type wave power generation device according to the present invention, two rods arranged in parallel are used as floating bodies, and a floating body base is passed between the rod-like bodies, and the gyro, the speed increaser, and the generator are accommodated by the floating body base. If the lower surface of the floating body base is positioned higher than the water contact surface of the rod-shaped body, the area of the landing portion is reduced, and the entire device can easily tilt even with a small wave, enabling power generation. can do. Further, the direction of the floating body with respect to the wave can be easily changed, and the moving resistance in the parallel axis direction of the rod-like body is small, so that the gyro wave power generator can be easily installed.

  In this case, the floating body base that supports the gyro can be smoothly tilted by connecting the rod-shaped body and the floating body base so as to be relatively rotatable about the connecting shaft extending in the length direction of the rod-shaped body. Can be generated efficiently.

  In a gyro-type wave power generator that uses two rod-shaped bodies as floating bodies, the overall vibration of the entire apparatus is greatest in the direction of the rotation vector that coincides with the parallel lines of the floating body, and the gyro moment is the rotation vector of the wheel support shaft and external force. Since the rotation occurs in the direction of the rotation vector that is perpendicular to both, if the wheel support shaft of the gyro is built perpendicular to the length direction of the rod-shaped body, a large gyro moment can be obtained and a large wave energy can be obtained. it can.

  Here, a capsule fitting recess having an inclined surface inclined in a direction opposite to the inner peripheral facing position is provided on the upper surface of the floating body base, and the lower part of the capsule is fitted into the capsule fitting recess to If it is supported by the bottom of the concavity and a cushioning material is built in between the inclined surface and the lower outer peripheral surface of the capsule, the impact force will be increased when the mooring is released due to a storm, etc., and collides with another ship or coastal facility. Can be buffered with a cushioning material, and the effect of preventing breakage of various devices in the capsule can be improved, and the degree of damage to the collision object can also be suppressed. Further, since the capsule can be easily separated and moved from the floating base at sea, maintenance and inspection work can be facilitated.

  In the gyro-type wave power generator according to the present invention, there are two sets of gyros, the two sets of gyros are assembled so that the gimbal axes are parallel, and the rotation direction of the flywheel is reversed, and the gimbal axis of each gyro Since the rotation shaft and the generator are connected to the same output shaft, the direction of the gyro moment is opposite between the two gyros. The rotation of the entire apparatus in the same direction as the rotation direction can be suppressed, the entire apparatus can be stabilized, and the decrease in rotation of the gimbal shaft can be suppressed.

  As described above, according to the present invention, the swinging motion of the entire device due to the wave is converted into the left and right rotational motion of the gimbal shaft by the gyro moment, and the rotational motion of the left and right direction of the gimbal shaft is changed to the engagement direction. By taking out to the output shaft through a pair of one-way clutches that are reversed, and inputting the rotation of the output shaft to the gearbox to drive the generator, the wave cycle and irregularity are reduced. Regardless, the generator can be rotated efficiently, and a gyro wave power generator with a large power generation capacity can be obtained.

  In addition, since it is not necessary to synchronize the oscillation cycle of the entire apparatus and the rotation of the gimbal shaft, a synchronous control device can be dispensed with and a low-cost gyro wave power generator can be provided.

Sectional drawing which expands and shows the gyro incorporation part of FIG. Vertical side view of FIG. (A) is the schematic of the rotation angle control means which controls the rotation angle of a gimbal axis | shaft, (b) is the schematic which shows an operation state. Longitudinal side view showing the swinging state of the gyro wave power generator Longitudinal front view showing another embodiment of the gyro wave power generator according to the present invention

  Embodiments of the present invention will be described below with reference to the drawings. As shown in FIGS. 1 and 2, the floating body 1 is composed of a pair of rod-shaped bodies 1a arranged in parallel, and a floating body base 2 is passed between the rod-shaped bodies 1a.

  The floating body base 2 has a pair of left and right connecting pieces 3 facing the opposite end surfaces in the length direction of the pair of rod-like bodies 1a, and each connecting piece 3 is connected to the upper end surface of the rod-like body 1a via a connecting shaft 4. It is connected rotatably.

  A capsule fitting recess 5 is formed at the center of the upper surface of the floating base 2. The capsule fitting recess 5 has a truncated pyramid shape, and each inner peripheral surface is an inclined surface 6. The lower part of the capsule 7 is fitted in the capsule fitting recess 5. The capsule 7 is supported by the bottom surface of the capsule fitting recess 5, and the lower part thereof has a truncated pyramid shape. A cushioning material 8 is incorporated between the outer peripheral surface of the capsule 7 and the inner peripheral surface of the capsule fitting recess 5.

  The capsule 7 has a cover 9 that can be opened and closed, and the internal space is partitioned into an upper space 11 and a lower space 12 by incorporating a base plate 10.

  As shown in FIGS. 3 and 4, a support ring 13 is incorporated in the lower space 12 of the capsule 7. The support ring 13 has a bearing cylinder 14 at the top and bottom, the lower bearing cylinder 14 is supported by the bottom plate 7 a of the capsule 7, and the upper bearing cylinder 14 is supported by the base plate 10 so as to be in a fixed arrangement.

  A gyro 15 is incorporated inside the support ring 13. The gyro 15 includes an inner hollow sealed gimbal 16, a flywheel 17 incorporated in the gimbal 16, and a motor 18 for driving the flywheel 17 to rotate.

  The gimbal 16 has a gimbal shaft 19 at the top and bottom. The gimbal shaft 19 is inserted into a bearing cylinder 14 provided in the support ring 13 and is rotatably supported by bearings 20 incorporated in the bearing cylinders 14. ing.

  The upper gimbal shaft 19 passes through a gear case 21 disposed in the upper space 11 and supported by the base plate 10 in the vertical direction, and is also rotatably supported by a bearing 22 supported by the upper wall of the gear case 21. .

  The flywheel 17 is fitted to a horizontally disposed wheel support shaft 23 which is orthogonal to the gimbal shaft 19 and both ends are fixedly supported by the gimbal 16, and is supported by a bearing 24 incorporated between the fitting surfaces. The wheel support shaft 23 is rotatable.

  Here, by reducing the pressure of the sealed internal space of the gimbal 16 with a decompressor, the rotational resistance of the flywheel 17 can be reduced, and the flywheel 17 can be smoothly rotated. At this time, since heat is accumulated in the gimbal 16 and the bearing 24 and the motor 18 that rotatably support the flywheel 17 are easily affected by heat, the wheel support shaft 23 is formed in a cylindrical shape so as to enhance the heat radiation effect. Yes.

  The motor 18 for rotationally driving the flywheel 17 employs an outer rotor type motor in which a rotor 18b is provided outside the stator 18a. The stator 18 is supported by a wheel support shaft 23, and the rotor 18b is attached to the flywheel 17. It is fixed.

  The gyro 15 having the above-described configuration is assembled so that the wheel support shaft 23 is orthogonal to the length direction of the two rod-shaped bodies 1 a forming the floating body 1. In the assembled state, the flywheel is driven by the motor 18. 17 is rotated at high speed, and the gyro 15 swings around a virtual center axis L passing through the center of gravity G of the flywheel 17 perpendicular to both the wheel support shaft 23 and the gimbal shaft 19 in the rotating state. When the tilt occurs, a gyro moment is generated by the rotation of the flywheel 17 so that the gimbal shaft 19 rotates in two forward and reverse directions.

  In the upper space 11, a rotation angle restricting means 25 for restricting the rotation angle of the gimbal shaft 19 in two forward and reverse directions is provided around the gimbal shaft 19. As shown in FIGS. 3 to 5, the rotation angle restricting means 25 is provided with a stopper 27 extending in the radial direction on the upper surface of the disk 26 fixed to the gimbal shaft 19, and is inclined in a direction opposite to both ends of the stopper 27. A spring pressing surface 28 is formed, and a pair of opposed spring supports 29 provided at 90 ° intervals on both sides in the circumferential direction from the stopper 27 are fixed on the upper surface of the base plate 10. A spring 30 is provided on both sides of the opposite end, and the stopper 27 presses the spring 30 until it reaches the contraction limit, thereby restricting the rotation angle in the left and right directions of the gimbal shaft.

  Here, θ in FIG. 5B indicates the movable range of the left rotation of the gimbal shaft 19, and the movable range of the gimbal shaft 19 is the same as the movable range of the left rotation.

  As shown in FIGS. 3 and 4, the gimbal shaft 19 is provided with a first drive gear 31 and a second drive gear 32, which are bevel gears, at portions located in the gear case 21. The first drive gear 31 and the second drive gear 32 are assembled so that their teeth face each other, and one-way clutches 33 and 34 are assembled between the fitting surfaces of the drive gears 31 and 32 and the gimbal shaft 19.

  The one-way clutch 33 incorporated inside the first drive gear 31 and the one-way clutch 34 incorporated inside the second drive gear 32 are incorporated in opposite directions with different engagement directions. One of the pair of one-way clutches 33 and 34 is engaged during rotation in one direction to transmit the rotation of the gimbal shaft 19 to one drive gear, and the other one-way clutch is engaged during rotation in the other direction of the gimbal shaft 19 Thus, the rotation of the gimbal shaft 19 is transmitted to the other drive gear.

  A driven bevel gear 35 meshes with each of the first drive gear 31 and the second drive gear 32. The driven bevel gear 35 is provided at the shaft end portion of the output shaft 36, the output shaft 36 extends in the horizontal direction and penetrates the peripheral wall of the gear case 21, and a flywheel 37 is provided at a portion located outside the gear case 21. Yes.

  The output shaft 36 is connected to a speed increaser 39 that increases the rotation speed of the output shaft 36 and outputs it to the generator 38.

  The gyro wave power generation device shown in the embodiment has the above-described structure, and FIGS. 1 and 2 show a state where the gyro wave power generation device is floated on the sea surface. When a wave is generated on the sea surface in the floating state, the entire apparatus is swung. FIG. 6 shows the swinging state. At this time, since the rod-shaped body 1a of the floating body 1 and the floating body base 2 are relatively rotatably coupled by the coupling shaft 4, the pair of rod-shaped bodies 1a move up and down in opposite directions while maintaining a certain posture, The floating base 2 swings due to the vertical movement in the opposite direction.

  In addition, since the bottom surface of the floating base 2 is located higher than the sea level, the area of the landing portion is small, and the floating base 2 swings even with a small wave, so that the entire apparatus swings smoothly.

  When the entire apparatus is swung as described above, the wheel support shaft 23 of the flywheel 17 has a virtual center axis L passing through the center of gravity G of the flywheel 17 perpendicular to both the wheel support shaft 23 and the gimbal shaft 19. The tilt is generated by swinging to the center.

  If the wheel support shaft 23 is tilted while the flywheel 17 is rotating at a high speed by the drive of the motor 18, a gyro moment is generated by the rotation of the flywheel 17 and the gimbal shaft 19 rotates.

  Here, since the wheel support shaft 23 is tilted by a wave, the tilt direction is changed, the direction of the gyro moment is also changed by the change of the tilt, and the gyro shaft 19 is rotated in two forward and reverse directions.

  At this time, the gyro shaft 19 is provided with a first drive gear 31 via a one-way clutch 33 and a second drive gear 32 via a one-way clutch 34, and the one-way clutches 33, 34. Since the direction of engagement is reversed, the one-way clutch is engaged by rotation of the gyro shaft 19 in one direction, and the rotation of the gyro shaft 19 in one direction is transmitted to one drive gear. Further, the other one-way clutch is engaged by the rotation of the gyro shaft 19 in the other direction, and the rotation of the gyro shaft 19 in the other direction is transmitted to the other drive gear.

  The rotation of the first drive gear 31 and the second drive gear 32 is transmitted to the output shaft 36 from the driven bevel gear 35 that meshes with each of the first drive gear 31 and the second drive gear 32, and the output shaft 36 is unidirectional. The rotation is increased by the speed increaser 39 and input to the generator 38, and the generator 38 is driven.

  Thus, when the wheel support shaft 23 swings due to the wave, the gimbal shaft 19 rotates in two forward and reverse directions, and the rotation is taken out as one direction rotation of the output shaft 36 and accelerated by the speed increaser 39. Therefore, the generator 38 can be efficiently rotated regardless of the wave period and irregularity.

  In the embodiment, the first drive gear 31 and the second drive gear 32 are bevel gears, and a driven bevel gear 35 that meshes with each of the bevel gears is provided on the output shaft 36, and the gimbal shaft 19 is forward / reverse. Since the rotational motion in two directions is extracted as one direction of rotation of the output shaft 36, energy loss is small and efficient power generation can be performed.

  Further, since the flywheel 37 is provided on the output shaft 36, the fluctuation of the rotational force transmitted to the driven bevel gear 35 is small, and the output shaft 36 is rotated by the inertial force of the flywheel 37. The rising of the rotational force when the one-way clutches 33 and 34 are engaged becomes smooth, and the output shaft 36 can be smoothly and continuously rotated in one direction.

  Further, the gimbal shaft 19 is provided with a stopper 27 extending in the radial direction, and the stopper 27 presses a pair of fixedly arranged springs 30 spaced apart in the circumferential direction to elastically deform until reaching the contraction limit. Since the rotation angle in the left and right directions of the gimbal shaft 19 is restricted, the wheel support shaft 23 that rotates together with the gimbal shaft 19 even if it receives a large gyro moment, the virtual center of the gimbal shaft 19 and the entire apparatus swings. The rotational movement to the opposite position across the surface including the shaft can be mechanically restricted. As a result, the gimbal shaft 19 can be reliably rotated in two forward and reverse directions along with the change in the swinging direction of the wheel support shaft 23. Further, the rotational direction of the gimbal shaft 19 can be smoothly switched by the restoring elasticity of the spring 30.

  Instead of the mechanical rotation angle restricting means 25 as described above, the rotation load of the generator 38 may be varied in proportion to the rotation angle displacement and rotation speed of the gimbal shaft 19. Even in this case, even if the wheel support shaft 23 swings greatly and receives a large gyro moment, the wheel support shaft 23 that rotates together with the gimbal shaft 19 is a plane that includes the gimbal shaft 19 and the virtual central axis of the entire apparatus swing. The gimbal shaft 19 can be reliably rotated in two forward and reverse directions together with the change in the swinging direction of the wheel support shaft 23.

  In this case, as shown in FIG. 3, a detection sensor 40 for detecting the rotation angle of the gimbal shaft 19 is provided around the gimbal shaft 19 and a detection signal is output from the detection sensor 40 to the control device. Based on the detection signal input from the detection sensor, the applying means for applying the rotational load to the generator 38 is controlled.

  FIG. 7 shows another embodiment of the gyro wave power generator according to the present invention. In this embodiment, two sets of gyros 15 are assembled in the capsule 7, the two sets of gyros 15 are assembled with the gimbal shaft 19 in parallel, the rotation direction of the flywheel 17 is reversed, and the gimbal of each gyro 15 is It differs from the gyro wave power generator shown in FIGS. 1 to 6 in that the output shaft 36 to which the rotation of the shaft 19 is transmitted is shared and a speed increaser 39 and a generator 38 are connected to the output shaft 36. is doing. Since the other configuration is the same as that of the gyro wave power generation device shown in FIGS. 1 to 6, the same components are denoted by the same reference numerals and description thereof is omitted.

  As described above, by providing the two pairs of gyros 15 in which the rotational directions of the flywheel 17 are opposite to each other, the rotational directions of the gyro moments are opposite to each other. The rotation of the entire apparatus in the same direction as the 19-turn direction can be suppressed, the entire apparatus can be stabilized, and a decrease in rotation of the gimbal shaft 19 can be suppressed.
