DETAILED DESCRIPTION

[0023] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0024] Embodiment 1

[0025] Please see attached Figure 1-3 , a marine split-type shaft generator device, comprising:

[0026] A main engine 1, a main shaft 2, two split shaft flanges 3, two split rotors 4 and two split stators 5, wherein one end of the main shaft 2 is connected to the main engine 1, and the other end is connected to the stern propeller, the split shaft flange 3 is located in the middle of the main shaft 2, and the two split shaft flanges 3 are fixedly connected, the two split rotors 4 are respectively fixedly connected to the two split shaft flanges 3, the two split stators 5 are respectively located on the outsides of the two split rotors 4, and the two split stators 5 are connected to each other.

[0027] Specifically, the main engine 1 provides power to drive the rotation of the main shaft 2 and the stern propeller at the other end of the main shaft 2. At the same time, by installing a split rotor 4 on the main shaft 2 and setting a split stator matching the split rotor 4, the electric energy generated by the rotation of the split rotor 4 is processed by frequency conversion to supply power to the ship's power station system when the ship is sailing. It is worth noting that the split stator 5 should be provided with a device for frequency conversion processing of electric energy and transmitting electric energy to the ship's power station. Because it belongs to another transmission system, it will not be repeated in the present invention.

[0028] Specifically, the split stator 5 located on the lower side of the main shaft 2 is provided with a support seat 50 integrally formed therewith, the support seat 50 is provided with a gap adjustment component 6 movably connected thereto, and a threaded hole 500 is provided on the bottom wall of the support seat 50, and the threaded hole 500 is provided with a vertical bolt 501 threadedly connected thereto.

[0029] Specifically, the gap adjustment assembly 6 includes a base plate 60 and four L-shaped angle pieces 61, and the L-shaped angle pieces 61 are fixedly connected to the four corners of the base plate 60 in symmetrical positions, and at least two groups of L-shaped angle pieces 61 are respectively provided with transverse screw holes 610 and longitudinal screw holes 611, and the transverse screw holes 610 and the longitudinal screw holes 611 are respectively provided with matching transverse bolts 6100 and longitudinal bolts 6111.

[0030] Specifically, the support seat 50 is placed on the base plate 60, and is located in the middle of the four L-shaped angle pieces 61. The transverse bolt 6100 and the longitudinal bolt 6111 respectively pass through the transverse screw hole 610 and the longitudinal screw hole 611 to contact the support seat 50, and the vertical bolt 501 passes through the threaded hole 500 to contact the base plate 60.

[0031] In the process of using the main shaft 2 to rotate and drive the split rotor 4 to generate electricity, there is suction between the split stator 5 and the split rotor 4, so the gap control between the split stator 5 and the split rotor 4 is particularly important. Considering that the main shaft will move upward by 0.4mm after the bearing oil film is formed in the working state, it is necessary to ensure that the horizontal gap between the split stator 5 and the split rotor 4 is 3.3±0.35mm, the gap above is 3.3±0.35mm, and the gap below is 3.3±0.35mm during installation;

[0032] Since the position of the main shaft 2 is fixed, the position of the split rotor 4 is also relatively fixed. Therefore, a threaded hole 500 and a vertical bolt 501 are set on the support seat 50 to adjust the gap in the vertical direction (Z axis) of the split stator 5, and the horizontal (X axis) and vertical (Y axis) gaps of the split stator 5 are adjusted respectively by the horizontal bolt 6100 and the longitudinal bolt 6111.

[0033] Specifically, the vertical bolt 501, the transverse bolt 6100 and the longitudinal bolt 6111 are made of fine-thread bolts; considering that the gap variation between the split stator 5 and the split rotor 4 is small, the vertical bolt 501, the transverse bolt 6100, and the longitudinal bolt 6111 used to adjust the gap size are all made of fine-thread bolts to avoid the situation where the single adjustment amount of the coarse thread is too large.

[0034] Embodiment 2

[0035] Specifically, the split stator 5 is provided with at least one group of inner diameter adjustment components 7, and the inner diameter adjustment components 7 include two groups of fixed plates 70, two groups of displacement plates 71 and a position adjustment plate 72. The two groups of fixed plates 70 are respectively located on the outside and inside of the split stator 5, and at least one group of vertical slide grooves 700 are provided at symmetrical positions thereof. A horizontal rectangular through hole 7000 is provided in the middle position of the vertical slide grooves 700. Both ends of the two groups of displacement plates 71 are respectively slidably connected to the two groups of vertical slide grooves 700, and the position adjustment plates 72 pass through the rectangular through holes 7000 and contact the two groups of displacement plates 71 respectively.

[0036] Specifically, the position adjustment plate 72 is provided with a plurality of specifications with different thicknesses;

[0037] Considering that the gap adjustment component 6 can only adjust the gap by adjusting the split stator 5, if the original inherent gap between the split stator 5 and the split rotor 4 is too small, the gap adjustment component 6 will not be able to meet the standard no matter how it is adjusted. For example, the horizontal gap between the split stator 5 and the split rotor 4 is 3.30±0.35mm, the gap directly above is 3.30±0.35mm, and the gap directly below is 3.30±0.35mm. Theoretically, the inherent gap between the split stator 5 and the split rotor 4 is between 5.90mm and 7.30mm, which can be adjusted by the gap adjustment component 6. However, when the inherent gap between the split stator 5 and the split rotor 4 is greater than 7.30mm or less than 5.90mm, no matter how the gap adjustment component 6 is adjusted, it cannot ensure that the gap directly above and the gap directly below the split stator 5 and the split rotor 4 are within the standard range.

[0038] In this embodiment, the inherent gap is the gap between the split stator 5 and the split rotor 4 after it is equipped with a group of inner diameter adjustment components 7. By using the inner diameter adjustment components 7 and the position adjustment plates 72 of different specifications, the relative positions of the two groups of displacement plates 71 are directly changed, thereby changing the size of the inherent gap, and indirectly expanding the application scope of the split stator 5. The two groups of split stators 5 can be connected to each other and fix the inner diameter adjustment components 7 by clamping, or they can be connected to the split stators 5 separately and adjust the gap through the displacement plates 71 and the position adjustment plates 72.

[0039] Embodiment 3

[0040] At least one set of displacement sensors 51 is provided between the split stator 5 and the split rotor 4. Considering that the split rotor 4 and the main shaft 2 may be locked when the gap between the split stator 5 and the split rotor 4 becomes smaller, at least one set of displacement sensors 51 is provided to monitor the gap in real time. A critical line for timely alarm can be set according to actual conditions to solve the possible locking of the split rotor 4 and the main shaft 2 in advance, thereby avoiding the situation where the equipment is excessively worn and cannot be used or the service life is greatly shortened due to the locking.

[0041] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
