Description

Technical Field

[0001] The present invention relates to the technical field of underwater transmission and observation platform, and in particular to a full-sea-depth magnetic coupling dual-output transmission motor and a full-sea-depth three-dimensional pan-tilt platform. Background Art

[0002] Full-sea-depth cameras are one of the most effective means of obtaining intuitive visual images for underwater observation. Affected by the uneven deep-sea topography, the field of view of fixed-mounted full-sea-depth cameras often depends on the landing posture of the carrying platform. There is often a phenomenon that the camera field of view cannot cover the target area, affecting the effect and purpose of the observation.

[0003] Deep-sea gimbals produced at home and abroad can be used in underwater camera observation platforms, underwater sonar integration platforms, ROV underwater robot platforms and other fields. Very few of them are used in the full sea depth, and most of them do not exceed 6,000 meters. They can accurately position pitch and rotation, but the price is very expensive.

[0004] The existing deep-sea gimbals all use pressure-compensated dynamic seal technology. This technology immerses the motor in a sealed cabin filled with oil, and one end of the sealed cabin is connected to a pressure compensator. The pressure compensator is a piston-type structure that uses the piston's adaptive axial movement to the pressure of the marine environment to balance the pressure of the oil-filled sealed cabin and the external marine environment, so as to achieve a watertight seal between the oil-filled sealed cabin and the motor. At the same time, the radial extrusion between the Gly ring and the motor output shaft is used to achieve torque output in the form of dynamic seal of the output shaft. The output torque directly drives the gimbal to adjust the pitch and rotation. Limited by the high-pressure environment of the deep sea, it is difficult for this technology to achieve a long-term, stable and reliable operation method.

[0005] The factors that restrict the development of deep-sea underwater pan / tilt technology are the poor stability and reliability of pressure-compensated dynamic seal transmission technology, which are mainly manifested in the following aspects:

[0006] (1) When used in marine environments for a long time, the dynamic seal ring is prone to fatigue wear and corrosion aging, resulting in leakage of the oil-filled sealed cabin and transmission failure;

[0007] (2) As the diving depth increases, the oil pressure in the oil-filled sealed cabin increases, and the oil density and viscosity also increase, resulting in greater viscous resistance between the motor rotors. In addition, due to the radial extrusion friction between the seal ring and the output shaft, the overall output efficiency of the motor decreases, power consumption increases, and the noise is very loud;

[0008] (3) In addition to increasing with depth, viscous resistance is also proportional to the relative speed between the motor rotors. The higher the speed, the greater the viscous resistance, which slows down the response speed of the underwater pan-tilt mechanism. Summary of the invention

[0009] Based on this, the technical problem to be solved by the present invention is to provide a full-sea-depth magnetically coupled dual-output transmission motor and a full-sea-depth three-dimensional pan-tilt head with low power consumption, large transmission torque, high positioning accuracy, full-sea-depth pressure resistance, long underwater working time and stable and reliable movement.

[0037] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0038] It should be noted that in the description of the present invention, the terms "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer" and the like indicating directions or positional relationships are based on the directions or positional relationships shown in the drawings, which are only for the convenience of description, and do not indicate or imply that the device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the present invention. In addition, the terms "first" and "second" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0039] like Figure 1 As shown, the full-sea-depth magnetically coupled dual-output transmission motor includes two single-output transmission motors.

[0040] The single output transmission motor includes an outer magnetic rotor 45 , an outer magnetic rotor mounting shell 43 , an inner magnetic rotor 46 , an inner magnetic rotor mounting shaft 51 , a pan / tilt motor 52 , an isolation sleeve 44 , an intermediate cylinder 50 , a rear end cover 53 and a watertight connector 54 .

[0041] like Fig.10 As shown, the outer magnetic rotor 45 is composed of a ferromagnet, a yoke and an anti-corrosion metal layer, and the inner magnetic rotor 46 is composed of a ferromagnet and a yoke. The ferromagnets in the outer magnetic rotor 45 and the inner magnetic rotor 46 are permanent magnets of different magnetic poles that are evenly staggered and can generally be divided into 4 to 12 groups according to different magnetic coupling designs.

[0042] The outer magnetic rotor 45 is fixedly connected to the outer magnetic rotor mounting shell 43, and can be fixed together by gluing. The outer magnetic rotor mounting shell 43 is mounted on the outside of the isolation sleeve 44 through a bearing, and is specifically mounted on the outside of the isolation sleeve 44 through a first ceramic bearing 77 and a third ceramic bearing 79, and can rotate freely around its central axis relative to the isolation sleeve 44. An anti-sand damping plate 47 is provided at the third bearing 79 to protect the bearing.

[0043] The isolation sleeve 44, the intermediate cylinder 50, the rear end cover 53 and the watertight connector 54 form a closed cabin. Among them, a sealing ring 49 is arranged between the intermediate cylinder 50 and the isolation sleeve 44, and between the intermediate cylinder 50 and the rear end cover 53.

[0044] The pan-tilt motor 52 is located in the sealed cabin, and the pan-tilt motor 52 is installed on the intermediate cylinder 50. The inner magnetic rotor 46 is installed on the inner magnetic rotor mounting shaft 51, and the inner magnetic rotor mounting shaft 51 is fixedly connected to the motor shaft of the pan-tilt motor 52. The inner magnetic rotor mounting shaft 51 extends into the second ceramic bearing 78 in the inner cavity of the isolation sleeve 44. The inner diameter of the inner cavity 71 of the isolation sleeve 44 is much smaller than the inner diameter of the sealed cabin. The inner magnetic rotor mounting shaft 51 can rotate freely around its central axis relative to the isolation sleeve 44. The inner magnetic rotor 46 and the outer magnetic rotor 45 are combined into a magnetic coupling body. When the pan-tilt motor 52 is powered on, it can drive the inner magnetic rotor 46 to rotate, thereby coupling and driving the outer magnetic rotor 45 to rotate together with the outer magnetic rotor mounting shell 43, thereby realizing non-contact transmission of torque.

[0045] like Figure 8 As shown, the isolation sleeve 44 of this embodiment includes a sleeve body 72, a first mounting portion 73 located at one end of the sleeve body 72, and a second mounting portion 74 located at the other end of the sleeve body 72. An inner cavity 71 is formed in the sleeve body 72, and the inner side of the sleeve body 72 is the inner magnetic rotor 46, and the outer side is the outer magnetic rotor 45. The inner magnetic rotor mounting shaft 51 extends into the inner cavity 71, and the inner magnetic rotor 46 is mounted on the inner magnetic rotor mounting shaft 51 extending into the inner cavity. The inner diameter of the sleeve body 72 is slightly larger than the outer diameter of the inner magnetic rotor 46. The first mounting portion 73 is an extension of the sleeve body 72 in the radial direction, and the first mounting portion 73 is fixedly mounted with the intermediate cylinder 50. A third mounting portion 75 is also provided on the first mounting portion 73. The third mounting portion 75 is coaxially arranged with the sleeve body 72, and the inner diameter of the third mounting portion 75 is larger than the outer diameter of the sleeve body 72. The third mounting portion 75 is used to mount a third ceramic bearing 79. The second mounting portion 74 is used to mount the first ceramic bearing 77, and the outer diameter of the second mounting portion 74 is smaller than the outer diameter of the sleeve 72. A fourth mounting portion 76 is provided at the bottom end of the inner cavity of the sleeve 72, and the fourth mounting portion 76 is used to mount the second ceramic bearing 78, and the inner diameter of the fourth mounting portion is smaller than the inner diameter of the sleeve 72.

[0046] like Fig. 9As shown, the outer magnetic rotor mounting shell 43 of this embodiment includes a power output end 1111, a fifth mounting portion 1112 and a sixth mounting portion 1113. Preferably, the outer diameter of the power output end 1111 is smaller than the inner diameter of the fifth mounting portion 1112 and smaller than the outer diameter of the sixth mounting portion 1113. The fifth mounting portion 1112 is used to mount the first ceramic bearing 77. The inner side of the sixth mounting portion 1113 is used to mount the outer magnetic rotor 45, and the outer side is used to mount the third ceramic bearing 79. On the one hand, the design of this embodiment can greatly reduce the cavity volume of the sealed cabin, improve the compressive strength and rigidity, and improve the stability of the structure under the full sea depth pressure environment. On the other hand, it is suitable for full sea depth. The smaller cavity volume inside the isolation sleeve can reduce the thickness of the isolation sleeve between the inner magnetic rotor and the outer magnetic rotor, which is beneficial to increase the coupling torque between the inner magnetic rotor and the outer magnetic rotor and improve the output of power torque. The rear end covers of the two single-output transmission motors are fixed together by a sealing ring (for example, fixed by the X-axis, Y-axis integrated magnetic coupling motor connecting bolts 58) or the two rear end covers form a connecting end cover, and the two single-output transmission motors share one connecting end cover, thereby forming a dual-output transmission motor.

[0047] This embodiment adopts magnetic coupling technology, realizes non-contact transmission of power through the attraction and repulsion between permanent magnetic materials installed on the master and slave poles in the transmission component, and realizes zero leakage of the sealed cabin by static sealing. Preferably, the power transmitted by the transmission motor is equipped with a speed reduction mechanism with a self-locking function, which can realize stable rotation and precise positioning of the pan / tilt in three dimensions of space.
