DETAILED DESCRIPTION OF THE EMBODIMENTS

[0020] The technical solutions in the embodiments of the present utility model will be clearly and completely described below. Apparently, the described embodiments are only a part of the embodiments of the present utility model, rather than all of them. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0021] Please refer to Figures 1 to 3, this embodiment provides an intelligent power distribution cabinet with an alarm function, including a power distribution cabinet housing 11, a control electrical appliance 19 and a circuit breaker 22 installed in the power distribution cabinet housing 11. A temperature detector 26 is installed in the power distribution cabinet housing 11, and an alarm device 27 for alarming is installed in the power distribution cabinet housing 11. The power distribution cabinet housing 11 is provided with a first ventilation opening 15 and a second ventilation opening 16. A cabinet door 12 with a handle 13 is installed on the power distribution cabinet housing 11, and the cabinet door 12 is provided with ventilation holes 14.

[0022] The control electrical appliance 19 and the circuit breaker 22 are common electrical equipment and will not be elaborated here. An internal controller for receiving the signal of the temperature detector 26, transmitting it to the alarm device 27, and opening and closing the signals of the solenoid valves at the nozzles of the moving assembly 17 and the nitrogen gas pipe 28 is installed in the power distribution cabinet housing 11.

[0023] After the temperature detector 26 encounters a temperature threshold exceeding its internal setting, the alarm device 27 will be activated. At this time, regardless of whether the temperature increase is caused inside or outside the cabinet, an alarm will be made through the loudspeaker provided inside the alarm device 27.

[0024] Both the first ventilation opening 15 and the second ventilation opening 16 are arranged outside the guide rail 23, so as to ensure that the folding cover plate 24 and the telescopic plate 20 enclose the entire control electrical appliance 19 and the circuit breaker 22 inside. This can ensure that during the process of cooling down and extinguishing the fire, air circulation can be reduced or isolated, so as to better carry out the fire extinguishing treatment.

[0025] A moving assembly 17 for driving the temperature detector 26 to move along the height direction of the power distribution cabinet housing 11 is arranged in the power distribution cabinet housing 11. The moving assembly 17 includes an empty slot 18 arranged on the inner wall of the power distribution cabinet housing 11. A lead screw 25 is rotatably connected in the empty slot 18, and the temperature detector 26 is threadedly connected to the lead screw 25.

[0026] When the temperature detector 26 detects that the temperature inside the power distribution cabinet housing 11 is too high, it will start the motor inside the power distribution cabinet housing 11 to drive the rotation of the lead screw 25, so as to adjust the position of the temperature detector 26 for local temperature detection. After the lead screw 25 is started, it will first drive the detector 26 to move up and down quickly once, and record the local temperature of the passing section in real time.

[0027] Nitrogen gas pipes 28 for fire extinguishing are arranged below both the control electrical appliance 19 and the circuit breaker 22, and nozzles with solenoid valves are arranged on the nitrogen gas pipes 28.

[0028] The nitrogen pipes 28 above and below are connected to each other. If, during the movement of the temperature detector 26, a position with a higher temperature is identified at one end of the control electrical appliance 19, the solenoid valve on the nitrogen pipe 28 closer to the control electrical appliance 19 is preferentially activated to preferentially consume nitrogen at one end of the control electrical appliance 19.

[0029] A guide rail 23 is provided inside the power distribution cabinet housing 11. A slider 21 is slidably connected to the guide rail 23. One end of a folding cover plate 24 is fixedly connected to the slider 21. A fixing rod 29 for fixing the other end of the folding cover plate 24 is provided inside the power distribution cabinet housing 11. A telescopic plate 20 is provided below the control electrical appliance 19 inside the power distribution cabinet housing 11.

[0030] Through the guide rail 23 and the electric slider 21, when it is necessary to isolate the air, the slider 21 can be activated first to stretch out the folding cover plate 24, and the telescopic plate 20 is extended. Acting together with the folding cover plate 24, the inside of the power distribution cabinet housing 11 is isolated. When nitrogen is sprayed, the weakening of the fire extinguishing effect due to the overly large overall area of the power distribution cabinet housing 11 during the spraying process can be avoided.

[0031] For those skilled in the art, it is obvious that the present utility model is not limited to the details of the above exemplary embodiments, and the present utility model can be implemented in other specific forms without departing from the spirit or basic characteristics of the present utility model. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-restrictive. The scope of the present utility model is defined by the appended claims rather than the above description. Therefore, all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be encompassed within the present utility model.
