DETAILED DESCRIPTION
[0018] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.
[0019] like Figure 1As shown, a multifunctional photovoltaic circuit breaker includes a circuit breaker body 1, wherein wiring holes 3 are provided at the upper and lower ends of the circuit breaker body 1, a push rod 4 is provided on the circuit breaker body 1, a driving mechanism 5 is provided on both sides of the push rod 4 on the circuit breaker body 1, and a lifting mechanism 6 is connected to the driving cylinder 504. Through the cooperation of the driving mechanism 5 and the lifting mechanism 6, multiple circuit breakers can be closed at one time instead of manually, thereby reducing the time required for closing the circuit breakers.
[0020] like Figure 2 Figure 3 As shown, the driving mechanism 5 includes a positioning foot 501 connected to the mounting groove 2, a mounting seat 503 is fixedly mounted on the positioning foot 501, a driving cylinder 504 is fixedly mounted on the mounting seat 503, a docking port 505 is provided at the bottom of the driving cylinder 504, a pressurized pipe 506 is connected to the docking port 505, a positioning through hole 502 is provided on the positioning foot 501, and a screw is provided in the positioning through hole 502, the positioning foot 501 is fixed in the mounting groove 2 by the screw, the mounting seat 503 is mounted on the circuit breaker body 1 through the positioning foot 501, the driving cylinder 504 is mounted on both sides of the push rod 4 through the mounting seat 503, the pressurized pipe 506 is connected to the driving cylinder 504 through the docking port 505, a notch is provided at the upper end of the driving cylinder 504, and the lifting pillar 603 extends out of the driving cylinder 504 through the notch.
[0021] Specifically, the drive cylinder 504 is installed on both sides of the push rod 4 on the circuit breaker body 1, and all the drive cylinders 504 are connected in parallel to the pressurized pipe 506 through the docking port 505. When the air pressure in the pressurized pipe 506 is increased, the air pressure below the drive cylinder 504 will increase. When the air pressure below the drive cylinder 504 increases, the piston 605 will be driven to move upward.
[0022] like Figure 2 Figure 4 As shown, the lifting mechanism 6 includes a piston 605 movably installed in the driving cylinder 504, a return spring 606 is provided in the driving cylinder 504 below the piston 605, a lifting support 603 is fixedly installed on the piston 605, a mounting hole 602 is provided at the upper end of the lifting support 603, a driving frame 601 is connected to the mounting hole 602, a docking groove 604 is provided on the piston 605, the lifting support 603 is installed on the piston 605 through the docking groove 604, the driving frame 601 is installed on the upper end of the lifting support 603 through the mounting hole 602, the lifting support 603 is movably installed in the driving cylinder 504 through the piston 605, one end of the return spring 606 is fixed on the piston 605, and the other end of the return spring 606 is fixed to the bottom of the driving cylinder 504.
[0023] Specifically, after the piston 605 moves upward, it will drive the lifting support 603 to move upward. After the lifting support 603 moves upward, it will drive the driving frame 601 to move upward. The upward moving driving frame 601 will push the push rod 4 upward, thereby replacing manual operation to close multiple circuit breakers at one time and reducing the time required to close the circuit breakers.
[0024] It should be noted that the utility model is a multifunctional circuit breaker for photovoltaic use. In actual use, the push rod 4 is first bent downward to disconnect the circuit breaker body 1. After the circuit breaker body 1 is disconnected, the circuit can be repaired. After the repair is completed, the air pressure in the pressurized pipe 506 can be increased. Since the pressurized pipe 506 is connected to the drive cylinder 504 through the docking port 505, the air pressure below the drive cylinder 504 will increase after the air pressure in the pressurized pipe 506 is increased. After the air pressure below the drive cylinder 504 increases, the piston 605 will move upward. At the same time, since the drive frame 601 is installed on the lifting support 6 through the installation hole 602 03, the lifting pillar 603 is movably installed in the driving cylinder 504 through the piston 605. Therefore, after the piston 605 moves upward, it will drive the lifting pillar 603 to move upward, and then drive the driving frame 601 to move upward. The driving frame 601 moving upward will push the push rod 4 upward, thereby replacing manual closing of multiple circuit breakers at one time, reducing the time required for closing the circuit breakers, and improving work efficiency. After all the circuit breakers are closed, the air pressure in the pressurized pipe 506 can be reduced. After the air pressure in the pressurized pipe 506 is reduced, the reset spring 606 will drive the piston 605 to reset, so that the driving frame 601 moves to the lowest point.
[0025] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
