It is one of the important system balances in the photovoltaic array system and can be used in conjunction with general AC-powered equipment. In addition, the inverter can also monitor the working status of photovoltaic components and lines. Once an abnormality is detected, such as component performance degradation or line failure, the inverter will issue an alarm in time. When potential dangers are detected, such as over-temperature, over-voltage, over-current, etc., the inverter will quickly disconnect the circuit to prevent equipment damage and fire risks.

While the filter screen 583 can be used for airflow discharge, the airflow can also form a boosting effect of blowing the debris to the direction of the filter screen 583.

[0034] In the actual operation process, the device is firstly connected to the power supply, and the first motor 44 drives the first gear 45 to rotate after it starts working. Since the first gear 45 is meshed with the gear ring 46, when the first gear 45 rotates, the connecting plate 42 rotates inside the annular plate 3, and the connecting plate 42 drives the rectangular frame 41 to rotate. After the second motor 49 starts working, it drives the threaded adjustment rod 48 to rotate, and the threaded adjustment rod 48 drives the moving block 47 to move, and the moving block 47 drives the auxiliary frame 491 to move, and the auxiliary frame 491 drives the lifting plate 492 to move, and the lifting plate 492 drives When the mounting seat 493 moves, it can be known from the above connection relationship that the horizontal position of the clamping plate 496 can be adjusted. Through the above operation, when the rectangular frame 41 is controlled to rotate, the end direction of the rectangular frame 41 can be adjusted, so that the end can point to the storage area of ​​the parts to be processed or the unloading area of ​​the parts after processing. After the orientation is adjusted, the clamping plate 496 can be quickly moved to the clamping or unloading position to perform the loading or unloading operation by controlling the movement of the moving block 47, which is more time-saving and labor-saving than manual handling. After the second electric push rod 485 works, it pushes and pulls the adjustment plate 484. During the movement of the adjustment plate 484, the push-pull rod 486 is driven to flip. After the push-pull rod 486 flips, it pushes and pulls the movable frame 494. When the adjustment plate 484 is away from the mounting seat 493, the two movable frames 494 move away from each other. Conversely, the two movable frames 494 move toward each other. The movable frame 494 drives the U-shaped plate 495 to move, the U-shaped plate 495 drives the round rod 497 to move, and the round rod 497 drives the clamping plate 496 to move. In this way, the two clamping plates 496 can be controlled to clamp the parts or release the materials after processing. On this basis, after the first electric push rod 483 works, it pushes and pulls the lifting plate 492 to control the lifting and lowering of the lifting plate 492. The lifting plate 492 drives the mounting seat 493 to lift and lower. In this way, the lifting and lowering of the clamping plate 496 can be further controlled. In this way, the height of the clamped parts can be adjusted so that different height areas thereof can be polished. During specific grinding processing, the third motor 55 drives the grinding wheel 56 to rotate after working. At this time, the fourth electric push rod 58 pushes and pulls the movable seat 52 after working, and the movable seat 52 drives the bottom block 53 to move, and the bottom block 53 drives the vertical plate 54 to move. It can be known from the above connection relationship that at this time, the position of the grinding wheel 56 is adjusted along the x-axis direction to adjust the distance between the grinding wheel 56 and the component. After the grinding wheel 56 contacts the component, the component can be ground. After the fifth electric push rod 59 works, the position of the bottom block 53 is adjusted along the y-axis direction, so that different positions of the component can be ground. After the single side of the component is ground, the third electric push rod 473 works to push and pull the movable seat 52, and the movable seat 52 drives the bottom block 53 to move, and the bottom block 53 drives the vertical plate 54 to move. The movable plate 489 is pushed and pulled, and the movable plate 489 drives the rack 472 to move, the rack 472 drives the second gear 471 to rotate, the second gear 471 drives the square rod 498 to rotate, the square rod 498 drives the two sleeves 499 to rotate, the sleeve 499 drives the first pulley 481 to rotate, the first pulley 481 drives the second pulley 482 to rotate through the belt, the second pulley 482 drives the round rod 497 to rotate, and the round rod 497 drives the clamping plate 496 to rotate. At this time, the two clamping plates 496 synchronously drive the clamped parts to turn over and change surfaces to achieve the purpose of multi-faceted grinding, which is more flexible than the fixed angle clamping device and has higher processing efficiency; Finally, during the movement of the above bottom block 53, the bottom block 53 also drives the positioning plate to move, and the positioning plate drives the dust hopper 593 to move, so as to ensure that the dust hopper 593 is always under the grinding wheel 56. While the above grinding work is in progress, the fan 594 absorbs the debris generated during the grinding process after it works, and the debris passes through the dust hopper 593 and the bellows 592 and enters the interior of the frame plate 591. The filter plate 595 filters and intercepts the debris in the airflow. When a lot of debris accumulates on the filter plate 595, the fourth motor 599 works and drives the threaded control rod 598 to rotate. The threaded control rod 598 drives the push plate 596 to move toward the outside of the frame plate 591. The push plate 596 opposite to the moving direction can The debris on the filter plate 595 is pushed outward from the frame plate 591, so that the debris can be flexibly pushed outward from the openings on both sides of the frame plate 591. After being pushed out, the debris falls on the inclined bottom surface 581 at the bottom of the shell 57, and slides toward the door panel 582 through the inclined bottom surface 581, thereby ensuring smooth airflow through the filter plate 595 and ensuring the adsorption quality. During this period, the filter net 583 on the door panel 582 can be used to discharge the airflow generated by the fan 594 when it is working to the outside of the door panel 582. When the airflow flows, it will also have the effect of blowing the debris on the inclined bottom surface 581, which can accelerate the debris to slide downward. After the user opens the door panel 582, the debris in the shell 57 can be cleaned up uniformly, which is very convenient.

[0035] The above are all preferred embodiments of the present invention, and are not intended to limit the protection scope of the present invention. Therefore, any equivalent changes made based on the structure, shape, and principle of the present invention should be included in the protection scope of the present invention.
