Embodiment Construction

[0014] The motor-driven magnetic coupling non-contact cable reel for deep water is mainly used in the winding operation of steel wire rope, cable, optical cable, hose, wire rope and other flexible cables in the range of 1500-10000 meters in water depth. In the embodiment of this design, the object to be wound is a steel wire rope with a diameter of φ3mm and a length of 30m. The structure is as follows: figure 1 As shown, the basic design parameters are: specification (length×width×height): 450×280×300mm; weight: 40kg. Other design parameters are: motor output shaft 40 diameter φ15mm; rolling bearing 26 type: 30220; drum 14 outer diameter: φ220mm; end cover support rod 6 diameter: φ16mm; guide post 4 diameter: φ5mm; inner rotor 41 outer diameter: φ56mm; Outer rotor 11 inner diameter: φ82mm; stator 9 outer diameter: φ80mm; stator end screw 8: M5; guide post nut 2: M3; end cover support rod screw 5: M10; drum left support connecting screw 16: M6; stator connection Screw 21: M6; ...

Abstract

The invention provides a motor-driven magnetic coupling non-contact rope drum for deep water, comprising a left end cover, a right end cover, a drum outer barrel, an end cover support bar, a drum, a drum left support, a drum right support, a motor base, a motor, an inner rotor, an outer rotor, an inner magnetic block, an outer magnetic block, a stator, a stator seal ring and a motor base end cover, wherein the motor is fixed in the motor base; the motor base and the stator isolate the output shaft of the motor from the outside seawater through the stator seal ring; the output shaft of the motor drives the inner magnetic block to rotate; the change of the magnetic field of the inner magnetic block drives the outer magnetic block to rotate through magnetic field coupling; the inner magnetic block and the outer magnetic block are isolated with each other through the stator; the outer magnetic block is immersed in the water; the inner magnetic block is sealed by the stator to be not in contact with the water; and the outer magnetic block drives the drum left support to rotate, thereby driving the drum to rotate. The motor driving magnetic coupling non-contact rope drum for the deep water can carry out winding and retracting and releasing operations on a steel rope within the water depth range of 1500-10000m.

Description

technical field [0001] The invention provides a cable drum structure used in deep water. Background technique [0002] For the motor drive of the slewing mechanism in deep water, its key problem is how to solve the problem of adapting the dynamic seal of the motor output shaft to the water depth of 1500-10000m (15-100MPa). There are mainly four methods for underwater dynamic sealing technology, namely: O-ring seal, combined seal of O-ring and PTFE slip ring, mechanical seal, and magnetic fluid seal. The specific characteristics are: ① general rubber O The sealing pressure of the ring should not exceed 1.5MPa, and at the same time, the linear velocity of rotation should be within 3.5m / s; ②The sealing pressure of the combined seal is 0-70MPa, which can be used in water depths within 7000 meters, and the linear velocity of rotation is 6m / s ③Magnetic fluid seal, the maximum single-stage sealing capacity can be 120kPa~180kPa, the entire sealing capacity is difficult to exceed 1....
