[0015] The present invention provides a power distribution cabinet with temperature regulation function. It has the following beneficial effects:

[0016] (1) The invention disconnects the electrical connection between the switch and the wire after the switch detects an overload, so that the power supply is cut off immediately when an overload occurs, preventing the overload from causing damage to more electrical components, thereby improving the protection of the device. The power-off valve pushes the transmission block, which releases the limit of the insulating rod. The insulating rod pushes the power supply, and the movement of the power supply disconnects the electrical connection with the wire, so that the power supply to the wire will also be disconnected after the switch is powered off, preventing the other switches from being overloaded due to continuous power supply after one of the switches is powered off, further improving the protection and safety of the device.

[0017] (2) The invention detects the fire source through the smoke alarm, then activates the solenoid valve to open the fire extinguisher, quickly extinguishes the fire source, and prevents the fire source from coming into contact with electricity, which may cause an electrical fire, making the fire uncontrollable and increasing the difficulty of firefighting. It also improves safety. When the smoke alarm cannot be activated normally, as the fire source increases, the rope loses tension after the fire source ignites the flammable plate, and the sliding block drives the T-block to move and open the solenoid valve, preventing the smoke alarm from being unable to detect a fire due to long-term standby or damage. The fire extinguisher can also be activated by the device even when the smoke alarm is damaged, further improving the reliability and practicality of the device.

[0018] (3) This invention detects the temperature inside the box through a temperature sensor and starts the fan when the temperature is too high. The fan will discharge the hot air inside the box through the vents to prevent the temperature inside the box from being too high and causing damage to the electrical components. This further improves the stability during operation. The limit ring is released by rotating the long rod. The limit ring will open the rolled-up shutter plate when it is rotated. When the shutter plate is extended, it will block the vents, making it impossible for air to circulate through the vents. This prevents the circulating air from fueling the fire when a fire occurs. The fire source can be effectively extinguished by the fire extinguisher, further improving the safety and reliability of the device. BRIEF DESCRIPTION OF THE DRAWINGS

A sliding groove is provided on the surface of the hollow cylinder 84, and the T-block 89 is fixedly mounted on the side of the sliding block 86 away from the flammable plate 85 to prevent the smoke alarm 81 from being unable to detect a fire due to long-term standby or damage, so that the fire extinguisher 82 can also be started by the device when the smoke alarm 81 is damaged, thereby further improving the reliability and practicality of the device.

[0036] A No. 3 spring 88 is arranged between the sliding block 86 and the hollow cylinder 84 . A rotation groove is provided at the bottom of the hollow cylinder 84 , and the No. 3 spring 88 drives the sliding block 86 to reset.

[0037] The smoke alarm 81 is internally provided with a No. 2 sensing module and a No. 2 control module, the No. 2 control module is electrically connected to the solenoid valve 83, the T-block 89 is in contact with the output end of the solenoid valve 83, and the solenoid valve 83 is started to work through the No. 2 control module.

[0038] The ventilation device includes: a rotating plate 91, a long rod 92, a fixed rod 93, a rolling shutter plate 94, a counterweight 95, a limit ring 96 and a locking plate 97.
