Description

Technical Field

[0001] The invention relates to the technical field of shaft generators, in particular to a high-efficiency marine shaft generator expansion device. Background Art

[0002] Generators are essential equipment for ships that frequently sail at sea. Normally, marine generators are directly connected to transmission mechanisms. However, this method takes up more space. Some small and medium-sized ships do not have enough space to accommodate this method. Therefore, the generator and transmission mechanism are placed side by side and then driven by belts and pulleys. However, after long-term use, the belts will become loose, reducing the transmission efficiency.

[0003] In order to maintain stable transmission when the belt is working, the existing patent announcement number is CN221610505U, which is a high-efficiency marine shaft generator tensioning device that can resist the belt, so that the belt and the pulley fit tightly to achieve stable transmission.

[0004] However, when the device is installed with the equipment, it is directly installed on the frame, which takes up a lot of space and is not conducive to the subsequent maintenance of the entire system. Position calibration is required during installation, which is cumbersome, time-consuming and labor-intensive. In addition, when installed on the frame, it is necessary to design in advance for the generator model and the installation space position, which is inconvenient to work quickly on different equipment, thereby reducing flexibility and practicality. Re-production and design take a lot of time, which is inefficient and costly. Moreover, the device is fixed after tension adjustment. When the belt loosens again after working for a long time, the staff needs to go to the site to operate and adjust again, which is time-consuming and labor-intensive and very inconvenient. At the same time, when adjusting the tension, the device uses precision accessories such as exposed screw rods and sliders for transmission control, which are prone to corrosion over time, causing gaps in the screw rods or sliders, affecting the tension control effect, and the supporting guide wheels are not easy to disassemble and assemble quickly, which is not conducive to subsequent maintenance or replacement, and the resistance component on the pressure wheel is not convenient for adjusting the resistance force of the transmission belt tension as needed, resulting in excessive extrusion of the transmission belt, which is easy to cause damage to the transmission belt after long-term work.

The installation of the base 1 facilitates the installation and placement of the support frame 201 and the generator 204. The installation of the two pulleys 202 facilitates the cooperation of the transmission belt 203, and facilitates the use of external power to drive the generator 204 to work, thereby generating current for external use.

[0039] Specifically, such as Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 and Figure 6 As shown, the tensioning mechanism 3 includes a mounting plate 304, an arc-shaped mounting plate 304 is installed at one end of the generator 204, and the mounting plate 304 is detachably connected to one end of the generator 204 through multiple slots 306 and bolts 305. A support rod 303 is installed at the edge of the mounting plate 304, and one end of the support rod 303 extends to the top side of the transmission belt 203. A connecting rod 301 is installed at one end of the support rod 303, and a connecting shaft 307 is vertically connected to the center of the side wall of one end of the connecting rod 301. A pressure wheel 302 is rotatably connected to the connecting shaft 307, and the pressure wheel 302 contacts the outer side of the top of the transmission belt 203.

The installation of the mounting plate 304 facilitates the connection of the support rod 303 and the connecting rod 301, thereby realizing the installation of the connecting shaft 307 and the pressure wheel 302. By the contact between the pressure wheel 302 and the transmission belt 203, the transmission belt 203 is contacted, so that the transmission belt 203 is tightened, which is beneficial to the good transmission effect of the two pulleys 202.

[0040] Specifically, such as Figure 3 、 Figure 4 and Figure 7As shown, the interference mechanism 4 includes a guide groove 401, an arc-shaped guide groove 401 is provided at the outer midline of the mounting plate 304, the bottom of the support rod 303 is slidably connected to the inside of the guide groove 401, the bottom of the support rod 303 and the guide groove 401 are both "convex" structures, an arc-shaped extrusion spring 403 is provided inside one end of the guide groove 401, one end of the extrusion spring 403 is connected to the inside of the mounting plate 304, and the other end of the extrusion spring 403 is connected to the inner side of the bottom of the support rod 303 through the mounting groove 404. Through the opening of the guide groove 401, the bottom of the support rod 303 can be The outer side of the mounting plate 304 slides in an arc shape, thereby enabling the pressure wheel 302 to adjust the extrusion height. Through the installation of the extrusion spring 403, under the interference of the extrusion spring 403, the support rod 303 drives the pressure wheel 302 to always maintain interference with the transmission belt 203, thereby keeping the transmission belt 203 always in a tensioned state, with high efficiency and stable transmission. The opening of the mounting groove 404 facilitates the stable installation of the extrusion spring 403 inside the mounting groove 404, and facilitates the guiding role when the length of the extrusion spring 403 changes.

[0041] Specifically, such as Figure 3 As shown, dust covers 402 are slidably connected to the outer sides of both ends of the guide groove 401, one end of the two dust covers 402 is respectively connected to the side walls of the end of the guide groove 401, and the other ends of the two dust covers 402 are respectively connected to the side walls of both ends of the support rod 303. Through the installation of the dust covers 402, it is beneficial to play a role in shielding and protecting the guide groove 401, preventing debris from entering the guide groove 401 and affecting the normal operation of the extrusion spring 403, and allowing the bottom of the support rod 303 to slide smoothly inside the guide groove 401 without getting stuck.

[0042] Specifically, such as Figure 3 、 Figure 4 、 Figure 7 and Figure 8As shown, the adjustment mechanism 5 includes a push block 504, one end of the mounting slot 404 is internally slidably connected to the push block 504, one end of the push block 504 is connected to the extrusion spring 403, a movable slot 502 is provided inside the bottom of the support rod 303, and the outer side of one end of the mounting slot 404 is connected to the movable slot 502, one side of the push block 504 is vertically connected to a connecting seat 505, one end of the connecting seat 505 is slidably connected to the inside of the movable slot 502, one end of the connecting seat 505 is rotatably connected to the driving rod 506, and one end of the movable slot 502 is rotatably connected to the screw 501, the top of the screw 501 extends to the outside of the support rod 303, and the bottom of the screw 501 is threadedly connected to the driving block 503, the driving block 503 is slidably connected to the inside of the movable slot 502, and one end of the driving block 503 is rotatably connected to one end of the driving rod 506, which is facilitated by the installation of the push block 504. The spring 403 is connected and controlled, and the installation of the screw 501 is conducive to the connection and control of the driving block 503. Through the rotation of the screw 501, the driving block 503 is driven to move inside the movable groove 502 under the cooperation of the thread, and the driving block 503 drives the driving rod 506 to contact the connecting seat 505, thereby causing the connecting seat 505 to drive the pushing block 504 to squeeze the squeezing spring 403, thereby compressing the squeezing spring 403, making the elastic force of the squeezing spring 403 larger, which is beneficial for the squeezing spring 403 to increase the squeezing force on the support rod 303, and is beneficial for the pressure wheel 302 to contact the transmission belt 203 more tightly, so that the transmission effect of the transmission belt 203 is better. The squeezing force of the pressure wheel 302 is adjusted by rotating the screw 501 forward and backward, which is convenient for adjusting the expansion tightness of the transmission belt 203 as needed.

[0043] Specifically, such as Figure 5 、 Figure 6 、 Figure 9 and Figure 11As shown, the telescopic mechanism 6 includes a rack 602, symmetrical racks 602 are installed on both sides of the support rod 303, the bottom of the connecting rod 301 is slidably connected to the inner side of the top of the support rod 303, the two racks 602 are located on the outside of the two sides of the connecting rod 301, and the inner side of the bottom of the connecting rod 301 is slidably connected with two symmetrical limit blocks 601, one end of the two limit blocks 601 extends to the outside of the connecting rod 301 and conflicts with the rack 602, one end of the limit block 601 is a toothed structure, and the other end of the limit block 601 is an arc structure, and a top block 603 is slidably connected at the inner midline of the bottom of the connecting rod 301, and a return spring 604 is connected between one end of the top block 603 and the connecting rod 301, and the top block 603 is a "cross" structure. The opposite ends of the two limit blocks 601 conflict with the two sides of the top block 603 respectively, through the bottom of the connecting rod 301 and the support rod The inner sliding connection at the top of 303 is conducive to adjusting the length of the connecting rod 301, thereby enabling the pressure wheel 302 to interfere with different positions of the transmission belt 203, with greater flexibility. By installing the two racks 602, under the interference of the top block 603, the two limit blocks 601 interfere with the two racks 602, thereby limiting the position between the connecting rod 301 and the inside of the support rod 303. By removing the external force of the top block 603, under the interference of the return spring 604, the top block 603 slides to a certain position, so that the outer side of the top block 603 does not interfere with the limit block 601, and the two limit blocks 601 are loosened from the rack 602, thereby enabling the connecting rod 301 to slide inside the support rod 303, and the limit block 601 will slide with the rack 602 to achieve the length adjustment of the connecting rod 301.

[0044] Specifically, such as Figure 3 、 Figure 5 、 Figure 6 、 Figure 9 and Figure 10As shown, the driving mechanism 7 includes a rotating rod 701, which is rotatably connected to the rotating rod 701 at the inner midline of the top of the connecting rod 301, and the top of the rotating rod 701 extends to the outside of the connecting rod 301. A turntable 703 is installed at the bottom of the rotating rod 701, and the turntable 703 is rotatably connected to the inside of the connecting rod 301 through the rotating rod 701. The side wall of the turntable 703 is provided with symmetrical driving grooves 705 and positioning grooves 704. The positioning grooves 704 and the driving grooves 705 are distributed at 90 degrees. The radius of the positioning grooves 704 is much smaller than the radius of the driving grooves 705. The driving grooves 705 are arc-shaped structures. A top rod 702 is slidably connected to the center of the inner part of the connecting rod 301. One end of the top rod 702 is an arc-shaped structure, and one end of the top rod 702 conflicts with the inner side of the positioning groove 704. The other end of the push rod 702 is connected to the push block 603. The installation of the rotating rod 701 facilitates the connection of the turntable 703. The installation of the push rod 702 realizes the drive control of the push block 603. The interference of the turntable 703 on the push rod 702 realizes the interference control of the push block 603 on the two limit blocks 601. With the cooperation of the positioning groove 704, the turntable 703 is not easy to rotate, which plays a positioning role. The rotating rod 701 is rotated 90 degrees, and the driving groove 705 is rotated to one end of the push rod 702. The push rod 702 will be inserted into the driving groove 705 under the interference of the return spring 604, so that the limit block 601 remains loose without external force, which is convenient for the sliding adjustment of the connecting rod 301.

[0045] Specifically, such as Figure 5 、 Figure 9 and Figure 10 As shown, the connecting mechanism 9 includes a connecting groove 902, and a connecting groove 902 is provided at the center of one side of the top of the connecting rod 301. One end of the connecting shaft 307 is engaged with the inside of the connecting groove 902. Both the one end of the connecting shaft 307 and the connecting groove 902 are hexagonal structures. Through the opening of the connecting groove 902, it is convenient for one end of the connecting shaft 307 to be detachably connected to the connecting rod 301, which is convenient for subsequent maintenance and replacement of different pressing wheels 302 as needed. Through the design of the hexagonal structure, the connecting shaft 307 will not rotate after being inserted and engaged with the connecting groove 902, which plays a stabilizing role.

[0046] Specifically, such as Figure 5 and Figure 10As shown, grooves 901 are provided on both sides of one end of the connecting shaft 307, and symmetrical protrusions 903 are installed on the inner side of the top of the connecting rod 301. The protrusions 903 are slidably connected to the inside of the connecting rod 301 through the interference springs 904, and the opposite ends of the protrusions 903 extend into the interior of the connecting groove 902 and interfere with the inner side of the groove 901. The groove 901 and one end of the protrusion 903 are both semicircular structures. Through the opening of the groove 901, when the connecting shaft 307 is inserted into the connecting groove 902, the protrusion 903 will be squeezed and contracted, so that the connecting shaft 307 can be fully inserted into the connecting groove 902. Finally, the protrusion 903 extends to the inside of the groove 901 under the interference of the interference spring 904, thereby limiting the connecting shaft 307. By pulling the connecting shaft 307 with a certain force, the protrusion 903 is again interfered and contracted, making it easy to disassemble the connecting shaft 307.

[0047] Specifically, such as Figure 5 、 Figure 10 and Figure 12 As shown, the locking mechanism 8 includes a locking groove 801, a side wall of one end of the connecting shaft 307 is provided with a locking groove 801, a clamping block 802 is installed on the inner side of the top of the connecting rod 301, the clamping block 802 is a "cross" structure, and compression springs 803 are connected between the two sides of the clamping block 802 and the inside of the connecting rod 301. One end of the clamping block 802 extends into the locking groove 801, and the other end of the clamping block 802 is an arc structure. The other end of the clamping block 802 conflicts with the positioning groove 704 on the outside of the rotating disk 703. When the turntable 703 is in contact with the clamping block 802, it is freed from the elastic force of the compression spring 803 and inserted into the locking groove 801, thereby limiting the connecting shaft 307 and making the connecting shaft 307 firmly installed. When the length of the connecting rod 301 is adjusted, the turntable 703 rotates, and one end of the clamping block 802 is inserted into the driving groove 705 in contact with the compression spring 803, so that the other end of the clamping block 802 is separated from the locking groove 801, which is convenient for disassembly and maintenance of the connecting shaft 307.

[0048] When the present invention is in use, first, the installation of the base 1 facilitates the installation and placement of the support frame 201 and the generator 204. The installation of the two pulleys 202 facilitates the cooperation of the transmission belt 203, facilitates the external power to drive the generator 204 to work, and then generates current for external use. The installation of multiple bolts 305 facilitates the detachable connection between the mounting plate 304 and one end of the generator 204. The cooperation of the card slot 306 facilitates the fast connection of the bolt 305 with different types of generators 204. The installation of the mounting plate 304 facilitates the connection of the support rod 303 and the connecting rod 301, and then realizes the installation of the connecting shaft 307 and the pressure wheel 302. The interference between the pressure wheel 302 and the transmission belt 203 realizes the transmission belt 2 The cam 303 of the second gear 202 is in the state of tension, and the ... The 1 shielding and protective function prevents debris from entering the guide groove 401 and affecting the normal operation of the extrusion spring 403, and enables the bottom of the support rod 303 to slide smoothly in the guide groove 401 without getting stuck. The installation of the push block 504 is conducive to the connection and control of the extrusion spring 403. The installation of the screw 501 is conducive to the connection and control of the driving block 503. The screw 501 is rotated to drive the driving block 503 to move in the movable groove 502 under the cooperation of the thread. The driving block 503 drives the driving rod 506 to contact the connecting seat 505, and then the connecting seat 505 drives the pushing block 504 to squeeze the extrusion spring 403, so that the extrusion spring 403 is compressed, and the elastic force of the extrusion spring 403 becomes larger, which is conducive to the extrusion spring 403 increasing the support The squeezing force of the support rod 303 is conducive to the tighter contact of the pressure wheel 302 with the transmission belt 203, so that the transmission effect of the transmission belt 203 is better. By rotating the screw 501 forward and backward, the squeezing force of the pressure wheel 302 is adjusted, which is convenient for adjusting the tightness of the transmission belt 203 as needed. The bottom of the connecting rod 301 is slidably connected to the inner side of the top of the support rod 303, which is conducive to adjusting the length of the connecting rod 301, thereby enabling the pressure wheel 302 to contact different positions of the transmission belt 203 with greater flexibility. Through the installation of the two racks 602, under the interference of the top block 603, the two limit blocks 601 contact the two racks 602 to realize the limit between the connecting rod 301 and the inside of the support rod 303. By removing the external force of the top block 603,Under the resistance of the return spring 604, the top block 603 slides to a certain position, so that the outer side of the top block 603 does not conflict with the limit block 601, and the two limit blocks 601 and the rack 602 are loose, so that the connecting rod 301 can slide inside the support rod 303, and the limit block 601 will slide with the rack 602 to achieve the length adjustment of the connecting rod 301. The installation of the rotating rod 701 is conducive to the connection of the turntable 703, and the installation of the top rod 702 is used to realize the drive control of the top block 603. The resistance of the turntable 703 to the top rod 702 is used to realize the top block 603 controls the two limit blocks 601 to resist each other. With the cooperation of the positioning groove 704, the turntable 703 is not easy to rotate, which plays a positioning role. By rotating the rotating rod 701 90 degrees, the driving groove 705 rotates to one end of the top rod 702. The top rod 702 is inserted into the driving groove 705 under the resistance of the return spring 604, so that the limit block 601 remains loose without external force, which is convenient for the sliding adjustment of the connecting rod 301. The opening of the connecting groove 902 is conducive to the detachable connection between one end of the connecting shaft 307 and the connecting rod 301, which is convenient for subsequent maintenance and The pressing wheel 302 can be replaced according to the need. The hexagonal structure design ensures that the connecting shaft 307 and the connecting groove 902 will not rotate after being inserted and engaged, thereby playing a stabilizing role. When the connecting shaft 307 is inserted into the connecting groove 902, the protrusion 903 will be squeezed and contracted, so that the connecting shaft 307 can be fully inserted into the connecting groove 902. Finally, the protrusion 903 extends to the groove 901 under the interference of the interference spring 904, thereby limiting the connecting shaft 307. By pulling the connecting shaft 307 with a certain force, The protrusion 903 is retracted again, making it easier to disassemble the connecting shaft 307. With the opening of the locking slot 801, under the interference of the rotating disk 703, the clamping block 802 is freed from the elastic force of the compression spring 803 and inserted into the locking slot 801, thereby limiting the connection shaft 307 and ensuring that the connection shaft 307 is firmly installed. When the length of the connecting rod 301 is adjusted, the rotating disk 703 rotates, and one end of the clamping block 802 is inserted into the driving slot 705 under the interference of the compression spring 803, so that the other end of the clamping block 802 is separated from the locking slot 801, making it easier to disassemble and maintain the connecting shaft 307.
