Detailed Implementation

[0035] 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.

[0036] like Figure 1 , Figure 2 , Figure 4 , Figure 7 , Figure 12 As shown, the present invention provides a safe and energy-saving shaft-driven generator, including a propeller shaft 1, a power generation structure 2 connected to the side of the propeller shaft 1, a positioning structure 3 connected between the power generation structure 2 and the propeller shaft 1, a fixing structure 4 provided on the inner side of the positioning structure 3, a support structure 5 provided on the bottom side of the power generation structure 2, an installation structure 6 provided on the side of the support structure 5, and a release structure 7 provided on the side of the power generation structure 2.

[0037] Specifically, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 10 , Figure 11 , Figure 12As shown, the power generation structure 2 includes a mounting base 201. The mounting base 201 is provided on the side of the propeller shaft 1. The shaft-driven generator body 202 is mounted on the mounting base 201. A gear sleeve 203 is fixedly connected to the propeller shaft 1. A transmission gear 204 is rotatably connected to the mounting base 201. The transmission gear 204 meshes with the gear sleeve 203. A first pulley 205 is provided on the side of the transmission gear 204. A second pulley 207 is mounted on the end of the shaft-driven generator body 202. The second pulley 207 is rotatably connected to the mounting base 201. A transmission belt 206 is sleeved between the first pulley 205 and the second pulley 207.

[0038] During installation, the mounting base 201 is moved to the side of the propeller shaft 1, so that the transmission gear 204 on the mounting base 201 meshes with the gear sleeve 203. When the propeller shaft 1 rotates, the transmission gear 204 drives the first pulley 205 to rotate, which in turn drives the input shaft of the shaft-driven generator body 202 to rotate through the transmission belt 206 and the second pulley 207, thereby generating electricity. Since the mounting base 201 is located on the side of the propeller shaft 1 and is driven by the separable gear sleeve 203 and transmission gear 204, the overall ease of disassembly and assembly of the generator is improved.

[0039] Specifically, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 7 , Figure 11 As shown, the positioning structure 3 includes a connecting seat 301. The connecting seat 301 is slidably connected to the side of the mounting seat 201. Two clamping blocks 303 are slidably connected to the side of the connecting seat 301. The two clamping blocks 303 are symmetrically arranged. An adjusting screw 302 is rotatably connected to the middle of the connecting seat 301. The two sides of the adjusting screw 302 have opposite thread directions. The two clamping blocks 303 are respectively threaded to the two sides of the adjusting screw 302. Two first pulleys 304 are rotatably connected to the two ends of the clamping blocks 303. The clamping blocks 303 abut against the side of the propeller shaft 1 through the first pulleys 304.

[0040] To ensure accurate meshing between the gear sleeve 203 and the transmission gear 204 during installation, a mounting base 201 is provided on the side of the mounting base 201. During motor installation, the mounting base 201 is moved so that the propeller shaft 1 is positioned between two clamping blocks 303. At this time, the adjusting screw 302 located on the top side of the connecting base 301 is rotated so that the clamping blocks 303 clamp the propeller shaft 1 through the first pulleys 304 on the side. Since there are two first pulleys 304 at each end of the clamping blocks 303, after the clamping blocks 303 clamp the propeller shaft 1 through the first pulleys 304, the propeller shaft 1 can be accurately positioned in the middle position of the connecting base 301, thereby ensuring the accuracy of the connection between the axis position of the propeller shaft 1 and the generator, and ensuring the stable transmission effect of the transmission gear 204.

[0041] Specifically, such as Figure 1 , Figure 7 , Figure 10 , Figure 11 As shown, the fixing structure 4 includes positioning blocks 402. Two positioning blocks 402 are slidably connected to the inner side of the connecting seat 301. The two positioning blocks 402 are symmetrically arranged, and a first spring 403 is fixedly connected between the two positioning blocks 402. A positioning groove 404 is provided on the inner side of the mounting seat 201. The ends of the positioning blocks 402 are engaged with the mounting seat 201 through the positioning groove 404. A pushing block 405 is slidably connected to the mounting seat 201 through the positioning groove 404. The end of the pushing block 405 abuts against the positioning block 402 arranged on the same side. A first inclined groove 406 is provided on the side of 5. The pushing block 405 is slidably connected to the abutting slide rod 408 through the first inclined groove 406. The abutting slide rod 408 is set perpendicular to the pushing block 405. A second spring 409 is fixedly connected between the abutting slide rod 408 and the mounting base 201. An operating rod 401 is rotatably connected to the inner side of the mounting base 201. A torsion spring 407 is fixedly connected between the operating rod 401 and the mounting base 201. A protruding structure is provided on the side of the operating rod 401. The top of the abutting slide rod 408 abuts against the protruding structure on the side of the operating rod 401.

[0042] During generator installation, after positioning the propeller shaft 1 using the fixing structure 4, the meshing calibration between the gear sleeve 203 and the transmission gear 204 can be completed by raising the height of the mounting base 201. A positioning groove 404 is provided on the inner side of the mounting base 201. When the mounting base 201 is raised until the positioning block 402 is aligned with the positioning groove 404, the positioning block 402 on the inner side of the connecting seat 301 will engage with the positioning groove 404 under the push of the first spring 403, thereby completing the height adjustment of the mounting base 201 and improving the efficiency of the overall generator installation position accuracy. On the other hand, by rotating the operating lever 401 on the side of the mounting base 201, the user can rotate the protruding structure on the side of the operating lever 401 and push the contacting slide bar 408 against it to the bottom. The end of the contacting slide bar 408 will further slide on the first inclined groove 406 on the side of the pushing block 405, and the positioning block 402 will be pushed away from the positioning groove 404 by the movement of the pushing block 405, which facilitates the reset of the connecting seat 301.

[0043] Specifically, such as Figure 1 , Figure 2 , Figure 3 , Figure 5 , Figure 10 , Figure 12As shown, the support structure 5 includes a support base 501. A drive rod 503 is rotatably connected to the middle of the support base 501. The drive rod 503 has reverse threaded structures on both sides. A movable crossbar 504 is threaded to each side of the drive rod 503. A support rod 505 is rotatably connected to the movable crossbar 504. The top end of the support rod 505 is rotatably connected to the bottom side of the mounting base 201. Multiple guide rods 502 are fixedly connected to the support base 501. The guide rods 502 are slidably connected to the mounting base 201. Four second pulleys 506 are rotatably connected to both ends of the movable crossbar 504. The four second pulleys 506 are arranged in a rectangular shape. A side sliding groove 507 is opened on the inner side of the support base 501. The second pulleys 506 are rolledly connected to the support base 501 through the side sliding groove 507.

[0044] When the drive rod 503 rotates, it can drive the movable crossbar 504 to move inside the support rod 505, thereby driving the support rod 505 to rotate, realizing the adjustment of the height of the mounting base 201 to adapt to the installation needs of generators on different ships. The two ends of the movable crossbar 504 slide between the second pulley 506 and the support base 501, making the movement and adjustment of the movable crossbar 504 smoother.

[0045] Specifically, such as Figure 1 , Figure 2 , Figure 3 , Figure 10 , Figure 12 As shown, the mounting structure 6 includes a third pulley 602, the third pulley 602 is rotatably connected to the bottom side of the support base 501, a plurality of fixing blocks 601 are slidably connected to the side of the support base 501, a third spring 603 is fixedly connected between the fixing blocks 601 and the support base 501, a release block 604 abuts against the top side of the fixing blocks 601, the release block 604 is slidably connected to the support base 501, a fourth spring 605 is fixedly connected between the end of the release block 604 and the support base 501, and a second inclined groove 606 is opened in the middle of the release block 604;

[0046] The support base 501 has a third pulley 602 on its bottom side. When clamping the clamping block 303 and the propeller shaft 1, and when the positioning block 402 disengages from the positioning groove 404, the support base 501 will slide synchronously to the position to be fixed as the clamping block 303 tightens. Multiple fixing blocks 601 are provided on the side of the support base 501. After the height adjustment of the mounting base 201 is completed, the positioning block 402 slides into the positioning groove 404 to fix the current installation height. Finally, the user can fix the generator as a whole through the fixing blocks 601. The fixing blocks 601 are provided with screw holes for fixing. In order to avoid the fixing blocks 601 from hindering the movement of the whole device, the fixing blocks 601 can be pressed by pressing the release block 604 on the side. When the release block 604 is no longer resisted, the fixing block 601 will slide to the top side under the push of the third spring 603. When installation is required, it can be moved directly to the bottom side through the second inclined groove 606 and fixed in position through the release block 604 to ensure a stable fixing effect on the support base 501.

[0047] Specifically, such as Figure 4 , Figure 6 , Figure 8 , Figure 9 As shown, the release structure 7 includes a rotating sleeve 702. The rotating sleeve 702 is slidably connected to the middle of the first pulley 205. A connecting block 703 is slidably connected to the end of the rotating sleeve 702. A fifth spring 704 is fixedly connected between the connecting block 703 and the rotating sleeve 702. The first pulley 205 is rotatably connected to the transmission gear 204. A insertion groove 705 is provided on the side of the transmission gear 204. The connecting block 703 is slidably connected to the transmission gear 204 through the insertion groove 705. A conversion rod 707 is rotatably connected to the side of the mounting base 201. A pulling block 701 is rotatably connected to the end of the conversion rod 707. 1. A slidable connection is made to the side of the mounting base 201. The end of the rotating sleeve 702 is rotatably connected to the pulling block 701. An arc groove 706 is provided on the side of the pulling block 701. A sliding column 711 is fixedly connected to the inner side of the conversion rod 707. The sliding column 711 is slidably connected to the pulling block 701 through the arc groove 706. A grip 708 is slidably connected to the end of the conversion rod 707. A sixth spring 709 is fixedly connected between the grip 708 and the conversion rod 707. A limiting arc groove 710 is provided on the side of the mounting base 201. The end of the grip 708 is engaged with the mounting base 201 through the end of the limiting arc groove 710.

[0048] The transmission gear 204 rotates synchronously with the first pulley 205, and the propeller shaft 1 can normally drive the input shaft of the shaft-driven generator body 202 to rotate. When it is necessary to disconnect the transmission, the user can slide the handle 708 at the end of the conversion rod 707 and rotate the conversion rod 707 to the other end of the limiting arc groove 710 along the limiting arc groove 710. At this time, the sliding column 711 set on the inner side of the other end of the conversion rod 707 will slide in the arc groove 706 on the side of the pulling block 701, and at the same time drive the pulling block 701 to pull the rotating sleeve 702 to slide outward, and finally drive the connecting block 703 to disengage from the insertion groove 705, thereby quickly disconnecting the transmission effect of the propeller shaft 1 to the input shaft of the shaft-driven generator body 202, which is convenient for operation.

[0049] In use, the present invention firstly has a gear sleeve 203 fixed on the propeller shaft 1 of the ship. During installation, the mounting base 201 is moved to the side of the propeller shaft 1, so that the transmission gear 204 on the mounting base 201 meshes with the gear sleeve 203. When the propeller shaft 1 rotates, the transmission gear 204 drives the first pulley 205 to rotate, which in turn drives the input shaft of the shaft-driven generator body 202 to rotate through the transmission belt 206 and the second pulley 207, thereby generating electricity. Since the mounting base 201 is located on the side of the propeller shaft 1 and is driven by the separable gear sleeve 203 and transmission gear 204, the overall ease of disassembly and assembly of the generator is improved. To ensure accurate installation of the gear sleeve 203 and the transmission gear 204... The mounting base 201 is located on the side of the mounting base 201. When installing the motor, the mounting base 201 is moved so that the propeller shaft 1 is positioned between two clamping blocks 303. At this time, the adjusting screw 302 located on the top side of the connecting base 301 is rotated so that the clamping blocks 303 clamp the propeller shaft 1 through the first pulleys 304 on the side. Since there are two first pulleys 304 at each end of the clamping blocks 303, after the clamping blocks 303 clamp the propeller shaft 1 through the first pulleys 304, the propeller shaft 1 can be accurately positioned in the middle position of the connecting base 301, thereby ensuring the accuracy of the connection between the axis of the propeller shaft 1 and the generator, and ensuring the stable transmission effect of the transmission gear 204. When installing the generator, the fixed structure 4 is used to... After the propeller shaft 1 is positioned, the meshing calibration between the gear sleeve 203 and the transmission gear 204 can be completed by raising the height of the mounting base 201. A positioning groove 404 is provided on the inner side of the mounting base 201. When the mounting base 201 is raised until the positioning block 402 aligns with the positioning groove 404, the positioning block 402 on the inner side of the connecting base 301 will engage with the positioning groove 404 under the push of the first spring 403, thereby completing the height adjustment of the mounting base 201 and improving the efficiency of the overall generator mounting position accuracy. On the other hand, by rotating the operating lever 401 on the side of the mounting base 201, the user can rotate the protruding structure on the side of the operating lever 401 and push the contact slide rod 408 against it to the bottom. The end of the contact slide rod 408 then... The first step involves sliding on the first inclined groove 406 on the side of the pushing block 405, and the movement of the pushing block 405 pushes the positioning block 402 away from the positioning groove 404, facilitating the resetting of the connecting seat 301. The bottom side of the mounting seat 201 is provided with a support seat 501, and the middle of the support seat 501 is provided with a drive rod 503 driven by a motor. When the drive rod 503 rotates, it can drive the moving crossbar 504 to move inside the support rod 505, thereby driving the support rod 505 to rotate, realizing the adjustment of the height of the mounting seat 201 to adapt to the installation needs of generators on different ships. The two ends of the moving crossbar 504 slide between the second pulley 506 and the support seat 501, making the movement and adjustment of the moving crossbar 504 smoother.A third pulley 602 is provided on the bottom side of the support base 501. This allows the support base 501 to slide synchronously to the required fixed position as the clamping block 303 tightens, and the clamping block 303 engages with the propeller shaft 1 and the positioning block 402 disengages from the positioning groove 404. Multiple fixing blocks 601 are located on the side of the support base 501. After the height adjustment of the mounting base 201 is completed, the positioning block 402 slides into the positioning groove 404 to fix the current installation height. Finally, the user can fix the generator as a whole using the fixing blocks 601. The fixing blocks 601 have screw holes for fixing. To prevent the fixing blocks 601 from obstructing the movement of the entire device, the fixing blocks 601 can be pressed by pressing the release block 604 on the side. After the release block 604 is released, the fixing block 601 will slide to the top side under the push of the third spring 603. When installation is required, it can be moved directly to the bottom side via the second inclined groove 606 and fixed in position by the release block 604, ensuring the support base 501 is securely fixed. For stable fixing, a rotating sleeve 702 is located between the first pulley 205 and the transmission gear 204. The rotating sleeve 702 is slidably connected to the inner side of the first pulley 205. The connecting block 703 at the end of the rotating sleeve 702 engages in the insertion groove 705 on the side of the transmission gear 204. At this time, the transmission gear 204 and the first pulley 205 rotate synchronously, and the propeller shaft 1 can normally drive the input shaft of the shaft-driven generator body 202 to rotate. When it is necessary to disconnect the transmission, the user can slide the handle 708 at the end of the conversion rod 707 and rotate the conversion rod 707 along the limiting arc groove 710 to the other end of the limiting arc groove 710. At this time, the sliding column 711 provided on the inner side of the other end of the conversion rod 707 will slide in the arc groove 706 on the side of the pulling block 701, and at the same time drive the pulling block 701 to pull the rotating sleeve 702 to slide outward, and finally drive the connecting block 703 to disengage from the insertion groove 705, thereby quickly disconnecting the transmission effect of the propeller shaft 1 to the input shaft of the shaft-driven generator body 202, which is convenient for operation.
