Description

Technical Field

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

[0002] Generators are essential equipment for ships that often go out to sea. Usually, marine generators are directly connected to the transmission mechanism, but the direct connection method takes up more space. Some small and medium-sized ships cannot provide enough space to meet the direct connection method. Therefore, the generator and the transmission mechanism are placed side by side, and then driven by belts and pulleys. However, the belts will become loose after long-term use, which reduces 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 belt generator tensioning device that can resist the belt, make the belt and the pulley fit tightly, and achieve stable transmission.

[0004] However, when the device is installed with the equipment, it is directly installed on the frame, which occupies a large amount of space, is not conducive to the subsequent maintenance of the entire system, and requires position calibration during installation, which is cumbersome, time-consuming and labor-intensive. When installed on the frame, it is necessary to design in advance for the generator model and the installation space position, which is not convenient for fast work on different equipment, thereby reducing flexibility and practicality. Re-production and design takes 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 the exposed screw rod and slider and other precision accessories for transmission control, which are prone to corrosion over time, causing gaps in the screw rod or slider, affecting the tension control effect, and the supporting guide wheel is not convenient for quick disassembly and assembly, 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 prone to damage to the transmission belt after working for a long time.

Through the installation of the dust cover 402, it is beneficial to play a guiding role in the guide groove 40 1. The shielding and protection function is to prevent debris from entering the guide groove 401 and affecting the normal operation of the extrusion spring 403, and to make the bottom of the support rod 303 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 rod 501 is conducive to the connection and control of the driving block 503. The screw rod 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 resist the connecting seat 505, so that the connecting seat 505 drives the push block 504 to squeeze the extrusion spring 403, so that the extrusion spring 403 is compressed, so that 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. The squeezing force of the pressure wheel 302 can be adjusted by rotating the screw rod 501 forward and backward, so that the expansion tightness of the transmission belt 203 can be adjusted according to needs. The bottom of the connecting rod 301 is slidably connected with the inner side of the top of the support rod 303, which is conducive to adjusting the length of the connecting rod 301, so that the pressure wheel 302 can contact different positions of the transmission belt 203, and the flexibility is stronger. Through the installation of the two racks 602, under the contact of the top block 603, the two limit blocks 601 contact the two racks 602, so as to limit the connection 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 resist the limit block 601, and the two limit blocks 601 and the rack 602 are loosened, 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 rotating disk 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 rotating disk 703 to the top rod 702 is realized. 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 will be 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 resistance, which is convenient for the sliding adjustment of the connecting rod 301. Through the opening of the connecting groove 902, it is convenient for one end of the connecting shaft 307 to be detachably connected with the connecting rod 301, which is convenient for subsequent maintenance and The pressing wheel 302 can be replaced according to the needs. The hexagonal structure design ensures that the connecting shaft 307 will not rotate after being inserted and engaged with the connecting groove 902, thereby playing a stabilizing role. The groove 901 is opened, and 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 completely inserted into the connecting groove 902. Finally, the protrusion 903 extends to the groove 901 under the resistance of the resistance spring 904, thereby limiting the connecting shaft 307. The connecting shaft 307 is pulled by a certain force. The protrusion 903 is retracted by the resistance again, which is convenient for the disassembly of the connecting shaft 307. Through the opening of the locking groove 801, under the resistance of the rotating disk 703, the block 802 is resisted to get rid of the elastic force of the compression spring 803 and insert into the locking groove 801, so as to limit the connecting shaft 307 and make the connecting shaft 307 firmly installed. When the length of the connecting rod 301 is adjusted, the rotating disk 703 rotates, and one end of the block 802 is inserted into the driving groove 705 by the resistance of the compression spring 803, so that the other end of the block 802 is separated from the locking groove 801, which is convenient for the disassembly and maintenance of the connecting shaft 307.
