[0002] The early warning device of the distribution cabinet is a system used for monitoring and early warning. It can monitor the operating status inside the distribution cabinet in real time, including electrical parameters, environmental conditions, mechanical status, etc., and issue an alarm when potential dangers or abnormal situations are detected.

[0003] In the application number CN202222318364.7, the "Anomaly Warning Device for Temperature and Humidity of a Distribution Cabinet" is disclosed. The problem that magnetic fixation is not stable is solved. Once there is a bump in the application place such as a ship, it is easy to fall. It is not meaningful to change the mounting plate to a pull-out type. In addition, the probe has no fixing measures. If it is placed directly in the distribution box, it will fit the box wall, the detection effect is inaccurate, and there is no function to flexibly adjust the position of the probe. However, the probe of the distribution cabinet fault warning device in the application can usually only detect and warn the air humidity. In practice, this monitoring method has certain limitations. When moisture penetrates into the inner wall or the upper and lower walls through the sealing strips, vents and other parts of the distribution cabinet, the humidity switch inside the distribution cabinet often cannot detect the change in humidity in time, and thus cannot issue a warning signal. In this way, moisture may gradually accumulate, affecting the performance of electronic components, and even causing serious faults such as short circuits, bringing safety hazards and property losses to the power system.

[0026] Embodiment 1:

[0027] A warning device for a power distribution cabinet comprises a power distribution cabinet structure 1, wherein the power distribution cabinet structure 1 comprises a protective outer box 101 and a box door 102, wherein the box door 102 is hingedly connected to one side surface of the protective outer box 101, a heat dissipation structure 4 is installed at the upper end of the inner surface of the power distribution cabinet structure 1, an electrical component group 2 is installed at the middle part of the inner surface of the power distribution cabinet structure 1, and an early warning structure 3 is installed at the inner bottom end of the power distribution cabinet structure 1, wherein the early warning structure 3 comprises a warning light 301, a guide block 302 and an outer frame 304, wherein the guide block 302 is fixedly installed at both ends of the inner lower surface of the protective outer box 101, and two guide blocks 302 are provided, wherein the guide block 302 is a triangular structure, and the outer frame 304 is fixedly installed between the two guide blocks 302, and lifting grooves 305 are provided on both side surfaces of the outer frame 304, wherein a lifting rod is fixedly connected to the inside of the lifting groove 305, and a lifting plate 306 is slidably connected to the surface of the lifting rod, and the upper end of the lifting plate 306 and the inner upper end of the lifting groove 305 are connected to each other. A spring structure 307 is arranged between the ends, a top block 308 is fixedly connected to the middle part of the upper surface of the lifting plate 306, a light switch 309 is installed on the upper end of the inner surface of the outer frame 304, and the light switch 309 is a press switch when it is self-reset. A warning light 301 is installed on the top of the protective outer box 101. The warning light 301 is a prior art, and the model of the warning light 301 is BZ200-12V with a buzzer warning light 301. When the warning light 301 is on, the buzzer sounds, thereby providing a visual and auditory warning reminder to the staff, and the inner bottom end of the outer frame 304 is connected with an expansion rubber 310, which is a prior art, and the expansion rubber 310 expands when it encounters water, so as to achieve the purpose of lifting the lifting plate 306 upward, the spring structure 307 is sleeved on the surface of the lifting rod, and a guide groove 303 is provided on the upper surface of the guide block 302, and the warning light 301 is electrically connected to the external power supply through the light switch 309.

[0028] During operation, when moisture seeps into the inside of the power distribution cabinet, the moisture flows into the bottom of the outer frame 304 at the lower end through the guide groove 303 of the guide block 302, and the moisture and the expansion rubber 310 contact each other, and the expansion rubber 310 begins to expand, pushing the lifting plate 306 up. The rise of the lifting plate 306 causes the top block 308 to press the light switch 309, causing it to be pressed, thereby lighting the warning light 301. At the same time, as the warning light 301 is lit, the buzzer connected to the warning light 301 sounds, giving a visual and auditory warning to the staff. After receiving the warning signal, the staff will immediately take corresponding measures to shut down the power distribution cabinet or take other emergency measures to ensure the safe operation of the power distribution cabinet. When the warning is lifted, the moisture inside the protective outer box 101 is cleaned, the expanded rubber 310 is taken out, and the unexpanded rubber 310 is put back into the bottom of the outer frame 304. The spring structure 307 pushes the lifting plate 306 downward, so that the top block 308 is away from the light switch 309. After the light switch 309 resets itself, the warning light 301 and the buzzer will automatically turn off and stop ringing, reminding the staff that the power distribution cabinet has returned to normal. During the whole process, the early warning structure 3 can operate flexibly and send out early warning signals in time to ensure that the staff can respond in time, effectively improving the safety performance of the power distribution cabinet.
