[0027] In this embodiment, four groups of support mechanisms 3 are provided, and storage slots 34 for storing support mechanisms 3 are opened in the bottom surface of the cabinet 1. During transportation, the support mechanism 3 can be rotated and hidden in the bottom surface of the cabinet 1, so that the bottom has a flat structure for easy transportation. When transported to the designated location, by flipping the legs 33 and rotating the shaft 32, and one side of the legs 33 is fitted into one side of the card receiving slot 34, the support mechanism 3 lifts the cabinet 1 as a whole, and the bottom surface of the cabinet 1 is separated from the ground to avoid being affected by ground moisture and to avoid being damaged by various insects and mice.

[0028] like Figure 4 As shown, the utility model provides a technical solution: preferably, the dehumidification mechanism 2 includes a negative pressure fan 23, a humidity monitor 24 is arranged on the negative pressure fan 23, a heating wire 22 is fixedly installed above the negative pressure fan 23, a protective net 21 is fixedly installed above the heating wire 22, eight groups of negative pressure fans 23 are arranged, and the humidity monitor 24 is used to monitor the humidity inside the cabinet 1.

[0029] In this embodiment, a humidity monitor 24 is provided on the negative pressure fan 23. When the humidity monitor 24 detects that the humidity inside the cabinet 1 is too high, the heating wire 22 heats up, and the negative pressure fan 23 rotates to generate negative pressure inside the cabinet 1, so that the external air is sucked into the cabinet 1 through the heating wire 22, thereby drying the interior of the cabinet 1 to prevent the internal electronic components from being affected by moisture and causing short circuits. The introduction of a dehumidification system can effectively improve the stable operation capability of the equipment in complex environments and reduce failures caused by environmental factors.

[0030] like Figure 5 As shown, the utility model provides a technical solution: preferably, the automatic fire extinguishing mechanism 5 includes a fire extinguishing agent tank 54, one end of the fire extinguishing agent tank 54 is connected with a nozzle 53, the nozzle 53 is electrically controlled to be connected with a solenoid valve 51, the solenoid valve 51 is electrically controlled to be connected with a temperature monitor 52, the automatic fire extinguishing mechanism 5 is provided with two groups located on the top inner wall of the cabinet 1, the heat dissipation mechanism 4 includes an intake fan 41, the heat dissipation mechanism 4 also includes an exhaust fan 42, the exhaust fan 42 and the intake fan 41 are respectively located on both sides of the top of the cabinet 1.

[0031] In this embodiment, when the temperature inside the cabinet 1 rises abnormally, the temperature monitor 52 opens the nozzle 53 through the solenoid valve 51 after monitoring, so that the fire extinguishing agent in the fire extinguishing agent tank 54 is sprayed out through the nozzle 53, and the electronic components inside the cabinet 1 are extinguished to avoid fire. In daily operation, the exhaust fan 42 and the air intake fan 41 located on both sides of the top of the cabinet 1 cooperate to form a circulating air duct, so that the air inside the cabinet 1 is continuously circulated to avoid heat accumulation. The low-voltage complete switchgear with a safety protection mechanism introduces a dehumidification, heat dissipation and automatic fire extinguishing system, which can effectively improve the stable operation capability of the equipment in a complex environment, reduce failures caused by environmental factors, and ensure that the equipment can maintain good working performance even in an undesirable environment and extend its service life.

[0032] The following is a detailed description of the working principle of the low-voltage switchgear with safety protection mechanism.

[0033] like Figure 1-5 As shown, the support mechanism 3 is provided with four groups, and the storage slots 34 for storing the support mechanism 3 are opened in the bottom surface of the cabinet 1. During transportation, the support mechanism 3 can be rotated and hidden and stored in the bottom surface of the cabinet 1, so that the bottom is a flat structure, which is convenient for transportation. After being transported to the designated location, by flipping the legs 33 and rotating the shaft 32, and one side of the legs 33 is attached to one side of the card receiving slot 34, the support mechanism 3 lifts the cabinet 1 as a whole, and the bottom surface of the cabinet 1 is separated from the ground to avoid being affected by ground moisture and various insects and mice from damaging it. A humidity monitor 24 is provided on the negative pressure fan 23. When the humidity monitor 24 detects that the humidity inside the cabinet 1 is too high, the heating wire 22 heats up, and the negative pressure fan 23 rotates to generate negative pressure inside the cabinet 1, so that the external air is sucked into the cabinet 1 through the heating wire 22, thereby drying the inside of the cabinet 1 to avoid the internal electronic components being affected by moisture. Into a short circuit, the introduction of a dehumidification system can effectively improve the stable operation capability of the equipment in a complex environment and reduce failures caused by environmental factors. When the temperature inside the cabinet 1 rises abnormally, the temperature monitor 52 monitors and then opens the nozzle 53 through the solenoid valve 51, so that the fire extinguishing agent in the fire extinguishing agent tank 54 is sprayed out through the nozzle 53 to extinguish the electronic components inside the cabinet 1 to avoid fire. In daily operation, the exhaust fan 42 and the air intake fan 41 located on both sides of the top of the cabinet 1 form a circulating air duct to continuously circulate the air inside the cabinet 1 to avoid heat accumulation. The introduction of a dehumidification, heat dissipation and automatic fire extinguishing system into the low-voltage complete switchgear with a safety protection mechanism can effectively improve the stable operation capability of the equipment in a complex environment and reduce failures caused by environmental factors. It can ensure that the equipment can maintain good working performance in an undesirable environment and extend its service life.
