[0025] The inside of mounting box 20 is provided with a detection mechanism, the detection mechanism is used for detecting the tripping phenomenon of circuit breaker 30 and issuing an alarm through sound and light alarm 43, so that the maintenance personnel can quickly locate the position of new energy storage equipment 10 that fails.

[0026] The detection mechanism includes photoelectric signal transmitter 41 and photoelectric signal receiver 42 installed in the inside of mounting box 20, the terminal position of blade 31 after tripping is in the detection area of photoelectric signal transmitter 41 and photoelectric signal receiver 42, the inside of mounting box 20 is also installed with controller 40, sound and light alarm 43 is fixedly installed on the outer top wall of mounting box 20, photoelectric signal transmitter 41, photoelectric signal receiver 42 and sound and light alarm 43 are electrically connected with controller 40 respectively; wherein, as Figure 4The position of the dotted line is the detection area of the photoelectric signal transmitter 41 and the photoelectric signal receiver 42, and attention should be paid when installing the circuit breaker 30. After the trip of the blade 31, the blade 31 should be in the position on the dotted line.

[0027] In addition, it should be noted that the inside of the installation box 20 is also provided with a power supply for supplying power to the electronic components inside the installation box 20.

[0028] The inside of the installation box 20 is provided with two sets of adjusting mechanisms for adjusting the installation position of the photoelectric signal transmitter 41 and the photoelectric signal receiver 42, one of which includes an adjusting plate 50 fixedly installed on the inner wall of the installation box 20, and an adjusting groove 51 is formed on the outer wall of the adjusting plate 50. The outer wall of the photoelectric signal transmitter 41 is fixedly installed with a mounting bracket 52, and the mounting bracket 52 is movably installed on the adjusting plate 50 through an adjusting assembly; in order to enable the photoelectric signal transmitter 41 and the photoelectric signal receiver 42 to detect the position of the blade 31 after tripping, the longitudinal installation position of the photoelectric signal transmitter 41 and the photoelectric signal receiver 42 can be adjusted. When adjusting the longitudinal installation position of the photoelectric signal transmitter 41 and the photoelectric signal receiver 42, the first locking nut 54 is counterclockwise, the fixing of the first locking nut 54 and the second locking nut 55 on the screw rod 53 is released, and then the longitudinal position of the screw rod 53 in the adjusting groove 51 is adjusted.

[0029] The adjusting assembly includes a screw rod 53 fixedly installed on the outer wall of the mounting bracket 52, and the first locking nut 54 and the second locking nut 55 are threadedly connected to the outer wall of the screw rod 53.

[0035] The above is only a preferred specific embodiment of the present application, but the protection scope of the present application is not limited thereto, any skilled person in the art can make equivalent replacement or change according to the technical scheme and the inventive concept of the present application within the technical range disclosed by the present application, which should be covered in the protection scope of the present application.
