Description

Technical Field

[0001] This invention relates to the field of shaft-driven generator technology, specifically a cooled shaft-driven generator for ships. Background Technology

[0002] A shaft-driven generator is a power generation device directly driven by the crankshaft of a ship's main engine or vehicle engine. It is widely used in large ships, locomotives, and other mobile platforms powered by large internal combustion engines. For shaft-driven generators on ships, they are mainly connected to the propulsion shaft of the ship's main engine through a mechanical transmission device. The gearbox solves the mismatch between the main engine shaft and the generator in terms of speed, steering, and power transmission requirements, converting part of the mechanical energy output by the main engine into electrical energy to stably supply power to the ship's power grid system.

[0003] Traditional shaft-driven generators are typically assembled and transported to the ship's hold using cranes. They are then secured to a pre-set base inside the hold using bolts and other fasteners. This process requires repeated alignment and tightening of the bolts during installation or maintenance, resulting in low installation efficiency. Furthermore, the compact layout of the generator parts makes it difficult to tighten the bolts with tools. Additionally, the continuous high-frequency vibration of the generator during operation can easily cause the bolts and nuts to loosen, resulting in poor stability. Generators are usually directly bolted to the base during installation. However, due to the operation of the ship's main engine and the turbulence of the voyage, continuous high-frequency vibrations are generated. These vibrations can easily cause the ship's shaft to misalign with the generator shaft system and the bolts of related equipment such as the gearbox to loosen. Therefore, a large flexible coupling is usually installed between the shaft and the main engine shaft. If the vibration is directly transmitted to the generator mounting base, it can easily cause the base to crack and be damaged, resulting in poor practicality. When connecting the generator shaft to the gearbox shaft, a coupling is usually used for fixation. However, if there is a slight deviation between the diameter of the shaft and the inner diameter of the coupling, making it difficult to fit precisely, forcibly fixing it can easily lead to loosening. Therefore, it is usually necessary to replace the coupling with a suitable one. The operation process is cumbersome, the installation efficiency is low, and the flexibility is poor.

Detailed Implementation

[0021] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0022] like Figures 1-3 ,and Figures 6-10 As shown, the present invention discloses a cooling shaft generator for ships, comprising a generator body 1, a mounting structure 4 located at the bottom of the generator body 1, a shock-absorbing structure 5 located on the mounting structure 4, and a fixing structure 6 connected to the shock-absorbing structure 5. The base 401 is then installed in a designated position inside the ship's cabin using four mounting blocks 402. Next, a crane is used to hoist the generator body 1, gearbox 2, and the entire assembly consisting of a load-bearing beam 403 and connecting plates 404 directly above the base 401. The mounting structure 4 includes the base 401, with the generator body 1 having a base 401 at its bottom. Two load-bearing beams 403 are located above the base 401. Mounting blocks 402 are fixedly connected to the four corners of the base 401. Two connecting plates 404 are fixedly connected between the two load-bearing beams 403. Two anti-impact blocks 405 are fixedly connected to the bottom of the load-bearing beams 403. The two ends of the base 401 are respectively fixedly connected to... Two positioning sleeves 406 are connected, and anti-impact blocks 405 are slidably connected to the positioning sleeves 406, so that the anti-impact blocks 405 at the bottom of the load-bearing beam 403 are aligned with the positioning sleeves 406 on the base 401, and the four anti-impact blocks 405 slide down along the positioning sleeves 406. At this time, the generator body 1 and gearbox 2 are accurately hoisted to the designated position inside the cabin, which is convenient for subsequent installation and easy to operate. The cross-section of the anti-impact block 405 is an "L" shaped structure. The top of the positioning sleeve 406 is provided with a slope. The generator body 1 and gearbox 2 are fixedly connected between the two connecting plates 404 respectively. The generator body 1 and gearbox 2 are connected by a docking structure 3. At the same time, the slope on the top of the positioning sleeve 406 is provided to facilitate the positioning of the anti-impact blocks 405, so that the anti-impact blocks 405 can be accurately moved between the four positioning sleeves 406. The setting of the anti-impact blocks 405 prevents the generator body 1 from falling off the base 401 under the action of inertia, which has strong stability.

[0023] Specifically, such as Figure 2 , Figure 3 and Figures 6-10As shown, during the operation of the generator body 1, the rotor rotation, piston movement, and electromagnetic effects inside the generator body 1 will generate severe vibrations. The damper 505 at the bottom of the sliding plate 503 can effectively prevent the vibration from being transmitted to the elastic structure of the hull through the base, prevent resonance with the natural frequency of the hull, and isolate the superimposed effects of the ship's rolling, pitching, and other movements and equipment vibrations during navigation. The vibration damping structure 5 includes a mounting frame 501 and a sliding plate 503 slidably connected to the mounting frame 501. The mounting frames 501 are fixedly connected to the four corners of the base 401. The two symmetrical mounting frames 501 are... A load-bearing beam 403 is provided. Two sliding rods 502 are fixedly connected to the mounting bracket 501. The sliding plate 503 is slidably connected to the sliding rods 502. A damper 505 is fixedly connected to the bottom of the sliding plate 503. A mounting seat 504 is fixedly connected to the base 401. The movable end of the damper 505 is fixedly connected to the mounting seat 504. At this time, the sliding plate 503 moves down along the two sliding rods 502. Since the damper 505 is installed between the sliding plate 503 and the mounting seat 504, the movable end of the damper 505 will move inward towards the fixed end, effectively playing a shock absorption role.

[0024] Specifically, such as Figure 1 , Figure 2 and Figures 7-10As shown, during the lowering of the load-bearing beam 403 and the generator body 1, the fixing structure 6 includes a second knob 601 and a sliding sleeve 602 threaded onto the second knob 601. The second knob 601 is rotatably connected to both ends of the load-bearing beam 403, and a first rack 606 is fixedly connected to both ends of the load-bearing beam 403. The sliding sleeve 602 is slidably connected to the load-bearing beam 403 and the first rack 606 respectively. A second rack 607 is fixedly connected to the sliding plate 503. The first rack 606 meshes with the adjacent second rack 607, and the arrangement of the first rack 606 and the second rack 607 further enhances the rigidity. When the load-bearing beam 403... When the first rack 606 at the bottom abuts against the second rack 607 on the slide plate 503 and the two mesh with each other, the connecting block 603 and the clamping block 604 automatically reset under the elastic force of the spring 605. At the same time, the protruding part at the bottom of the clamping block 604 abuts against the bottom surface of the slide plate 503. Thus, the two load-bearing beams 403 are initially fixed between the two pairs of mounting brackets 501. Then, the second knob 601 at the end of the load-bearing beam 403 is turned with a hex wrench. The second knob 601 drives the sliding sleeve 602 to move upward along the inner wall of the load-bearing beam 403. The sliding sleeve 602 drives the connecting block 603 and the clamping block 604 to move upward, so that the clamping block 603... 04 Further press the sliding plate 503, at which point the four clamping blocks 604 quickly install the generator body 1 and gearbox 2 onto the base 401, resulting in high operational efficiency and strong stability. A connecting block 603 is slidably connected inside the sliding sleeve 602, and a spring 605 is fixedly connected between the connecting block 603 and the sliding sleeve 602. Both the connecting block 603 and the clamping blocks 604 have inclined surfaces. The first rack 606 slides in engagement with the inclined surface at the end of the connecting block 603, and the sliding plate 503 slides in engagement with the inclined surface at the bottom of the clamping block 604. A clamping block 604 is fixedly connected to the connecting block 603, and the clamping block 604 is slidably connected to the load-bearing beam 403. The bottom of 4 abuts against the slide plate 503. When disassembly is required, simply rotate the second knob 601 on the load-bearing beam 403 in the opposite direction. At this time, the second knob 601 drives the sliding sleeve 602 to move down. The sliding sleeve 602 drives the connecting block 603 and the clamping block 604 to move down. During the downward movement of the connecting block 603, the inclined surface at its end slides and engages with the first rack 606, thereby driving the connecting block 603 and the clamping block 604 to slide outward until the protruding part at the bottom of the clamping block 604 is completely moved to the side of the slide plate 503. At this time, the load-bearing beam 403 and the generator body 1 can be quickly lifted by a crane, avoiding repeated alignment and disassembly of screws.

[0025] Specifically, such as Figure 1 and Figures 3-5As shown, the generator body 1 and gearbox 2 are respectively installed at designated positions on the two connecting plates 404. Next, the first rotating shaft 301 of the generator body 1 needs to be connected to the second rotating shaft 310 of the gearbox 2. The connection structure 3 includes the first rotating shaft 301, which is rotatably connected to the generator body 1, and the second rotating shaft 310 is rotatably connected to the gearbox 2. Two clamping shells 302 are provided between the first rotating shaft 301 and the second rotating shaft 310, and the two clamping shells 302 are fixedly connected by multiple bolts 309. The inner side of the clamping shell 302 abuts against a bushing 303, and the first rotating shaft 301 and the second rotating shaft 310 abut against each other between the two bushings 303. Only the first rotating shaft 301 and... The size of the second rotating shaft 310 is selected by choosing a bushing 303 of appropriate thickness. The bushing 303 is then installed on the clamping shell 302. Two positioning blocks 304 on the bushing 303 are inserted into pre-drilled holes in the clamping shell 302. The two assembled semi-circular clamping shells 302 are then placed between the first rotating shaft 301 and the second rotating shaft 310. At this point, two positioning plates 306 are positioned between the first rotating shaft 301 and the second rotating shaft 310, thus achieving initial fixation of the first rotating shaft 301 and the second rotating shaft 310. Two positioning blocks 304 are fixedly connected to the bushing 303, and the positioning blocks 304 are slidably connected to the clamping shell 302. A first knob 305 is threaded onto the clamping shell 302. The end of 05 abuts against bushing 303. Then, using a hex wrench, the first knob 305 on clamp 302 is turned. The end of the first knob 305 abuts against bushing 303, causing bushing 303 to press against the first rotating shaft 301 and the second rotating shaft 310, improving the firmness. Two positioning plates 306 are slidably connected between the two bushings 303. A drive block 307 is fixedly connected to the positioning plate 306. The drive block 307 is slidably connected to the bushing 303. A tension rod 308 is rotatably connected to both ends of one bushing 303. The drive block 307 is threadedly connected to the tension rod 308. The two positioning plates 306 abut against the first rotating shaft 301 and the second rotating shaft 310 respectively. Clamp 302 and All bushings 303 are semi-circular structures, and two positioning plates 306 are symmetrically arranged. Both positioning plates 306 have conical surfaces. Then, the two tension rods 308 on one of the bushings 303 are rotated respectively. The tension rods 308 drive the drive block 307 to slide along the inner wall of the bushing 303. At the same time, the drive block 307 drives the positioning plate 306 to press against the first rotating shaft 301. At this time, the shoulder of the first rotating shaft 301 is in contact with the conical surface on the positioning plate 306, which further improves the firmness and can quickly and accurately determine the axial position of the positioning plate 306 and the bushing 303 on the first rotating shaft 301, which is convenient for correcting axial offset during assembly. Finally, the two clamps 302 are fixed with bolts 309.

[0026] Specifically, such as Figure 1 and Figure 3As shown, a cooling structure 7 is connected to the generator body 1. The cooling structure 7 includes a control box 701 and wires 702 fixedly connected to the control box 701. Finally, multiple wires 702 are connected to the control box 701 on the top of the generator body 1. The control box 701 is fixedly connected to the top of the generator body 1. Cooling water pipes 703 are fixedly connected to the side wall of the generator body 1. The cooling water pipes 703 on the side wall of the generator body 1 are connected to external cooling water tanks, water coolers and other equipment. Since cooling water channels are set in the stator core, windings or casing of the generator body 1, the cooling water sent by the cooling water pipes 703 circulates in the water channels, carrying away the heat generated by the generator and achieving a cooling effect.

[0027] In use, the generator body 1 and gearbox 2 are respectively installed at designated positions on two connecting plates 404. Next, the first rotating shaft 301 of the generator body 1 needs to be aligned with the second rotating shaft 310 of the gearbox 2. This is achieved by selecting a bushing 303 of appropriate thickness based on the dimensions of the first and second rotating shafts 301 and 310. The bushing 303 is then installed on the clamping shell 302, and the two positioning blocks 304 on the bushing 303 are inserted into pre-drilled holes in the clamping shell 302. The two assembled semi-circular clamping shells 302 are then fitted between the first and second rotating shafts 301 and 310. At this point, the two positioning plates 306 are positioned between the first and second rotating shafts 301 and 310, thus achieving initial fixation of the first and second rotating shafts 301 and 310. Then... Turn the first knob 305 on the clamp 302 with a hex wrench. The end of the first knob 305 abuts against the bushing 303, so that the bushing 303 abuts against the first rotating shaft 301 and the second rotating shaft 310, which improves the firmness. Then, turn the two tension rods 308 on one of the bushings 303 respectively. The tension rod 308 drives the drive block 307 to slide along the inner wall of the bushing 303. At the same time, the drive block 307 drives the positioning plate 306 to abut against the first rotating shaft 301. At this time, the shoulder of the first rotating shaft 301 is in contact with the conical surface on the positioning plate 306, which further improves the firmness and can quickly and accurately determine the axial position of the positioning plate 306 and the bushing 303 on the first rotating shaft 301, which is convenient for correcting axial offset during assembly. Finally, use bolts 309 to fix the two clamps 302. Next, the base 401 is installed in the designated position inside the cabin using four mounting blocks 402. Then, using a crane, the generator body 1, gearbox 2, and the entire assembly consisting of the load-bearing beam 403 and connecting plate 404 are hoisted to the top of the base 401. Then, the load-bearing beam 403 is lowered so that the anti-impact block 405 at the bottom of the load-bearing beam 403 is aligned with the positioning sleeve 406 on the base 401. The four anti-impact blocks 405 slide down along the positioning sleeve 406. At this time, the generator body 1 and gearbox 2 are accurately hoisted to the designated position inside the cabin, which is convenient for subsequent installation and simple to operate. At the same time, the sloping top of the positioning sleeve 406 facilitates the positioning of the anti-impact blocks 405, allowing the anti-impact blocks 405 to move accurately between the four positioning sleeves 406. The anti-impact blocks 405 also prevent the generator body 1 from falling off the base 401 under inertia, resulting in strong stability. During the lowering of the load-bearing beam 403 and the generator body 1, the clamping blocks 604 at both ends of the load-bearing beam 403 will first abut against the sliding plate 503. At this time, the inclined surface at the bottom of the clamping block 604 slides against the sliding plate 503, causing the clamping block 604 to move outward. The clamping block 604 drives the connecting block 603 to slide outward along the inner wall of the sliding sleeve 602, compressing the spring 605, until the "L"-shaped clamping block 604 no longer obstructs the lowering of the load-bearing beam 403. When the first [unclear text - possibly a typo, should be "L"] at the bottom of the load-bearing beam 403... When rack 606 abuts against the second rack 607 on slide plate 503 and the two mesh with each other, connecting block 603 and clamping block 604 automatically reset under the elastic force of spring 605. At the same time, the protruding parts at the bottom of clamping block 604 abut against the bottom surface of slide plate 503. Thus, the two load-bearing beams 403 are initially fixed between the two pairs of mounting brackets 501, and the arrangement of the first rack 606 and the second rack 607 further enhances the firmness. Then, use a hex wrench to rotate the bearing... The second knob 601 at the end of the load-bearing beam 403 drives the sliding sleeve 602 to move upward along the inner wall of the load-bearing beam 403. The sliding sleeve 602 drives the connecting block 603 and the clamping block 604 to move upward, so that the clamping block 604 further presses against the sliding plate 503. At this time, the four clamping blocks 604 quickly install the generator body 1 and the gearbox 2 onto the base 401. The operation is efficient and the stability is strong. When disassembly is required, simply rotate the second knob 601 on the load-bearing beam 403 in the reverse direction. Button 601 drives the sliding sleeve 602 to move down, and the sliding sleeve 602 drives the connecting block 603 and the clamping block 604 to move down. During the downward movement of the connecting block 603, the inclined surface at its end slides and engages with the first rack 606, thereby driving the connecting block 603 and the clamping block 604 to slide outward until the protruding part at the bottom of the clamping block 604 is completely moved to the side of the sliding plate 503. At this time, the load-bearing beam 403 and the generator body 1 can be quickly lifted by the crane, avoiding repeated alignment and disassembly of screws. During the operation of the generator body 1, the rotor rotation, piston movement and electromagnetic effect inside the generator body 1 will generate severe vibration. The damper 505 at the bottom of the slide plate 503 can effectively prevent the vibration from being transmitted to the elastic structure of the hull through the base, prevent resonance with the natural frequency of the hull, and isolate the superposition of the effects of the ship's rolling and pitching movements and equipment vibration during navigation. At this time, the slide plate 503 moves down along the two slide rods 502. Since the damper 505 is installed between the slide plate 503 and the mounting base 504, the movable end of the damper 505 will move inward to the fixed end, effectively playing a shock absorption role. Finally, multiple wires 702 are connected to the control box 701 on the top of the generator body 1. At the same time, the cooling water pipes 703 on the side wall of the generator body 1 are connected to external cooling water tanks, water coolers and other equipment. Since the stator core, windings or casing of the generator body 1 are equipped with cooling water channels, the cooling water delivered by the cooling water pipes 703 circulates in the channels, carrying away the heat generated by the generator and achieving a cooling effect.
