when the temperature and humidity sensor 3 senses that the humidity inside the housing 1 reaches a set threshold value, the controller 31 controls the driving mechanism 7 to operate, so that the movable seat 53 moves towards the first exhaust fan 51, and the freedom degrees of the first exhaust fan 51 and the movable seat 53 in the rotating direction are limited through the arranged clamping mechanism 6; further, when the first exhaust fan 51 rotates, the second exhaust fan 52 is driven to rotate, and further, the second exhaust fan 52 blows the gas inside the housing 1 to the suction side of the first exhaust fan 51 (i.e., the area B in fig. 12); further, the gas acting on the first exhaust fan 51 obtains the initial speed same as the air outlet direction of the first exhaust fan 51, and further the second-stage acceleration of the gas blown to the outside from the inside of the housing 1 is realized (as shown in fig. 12, the gas in the area a enters the area B after the action of the second exhaust fan 52, since the spiral degree of the fan blades of the second exhaust fan 52 is larger than that of the fan blades of the first exhaust fan 51, further the air quantity sucked by the first exhaust fan 51 from the area B is smaller than the air quantity exhausted from the second exhaust fan 52 to the area B, further the area B forms a high-pressure area, the gas entering the area B obtains the moving speed towards the direction of the first exhaust fan 51, then the gas in the area B enters the action area of the first exhaust fan 51, the gas in the area B is acted by the first exhaust fan 51, further the gas in the area B is acted by the force again under the condition of a certain speed, further, the gas in the area B obtains acceleration again, so that the speed of the gas in the area B is further increased, further, the gas in the area B flows to the area C more quickly, and further, a stronger airflow is formed in the area C), and further, the speed of the gas blown out by the first exhaust fan 51 is faster;

thereby ensuring the safety of the electric equipment connected with the power distribution cabinet; when the temperature and humidity sensor 3 senses that the humidity inside the housing 1 reaches a set threshold value, the controller 31 controls the driving mechanism 7 to operate, so that the movable seat 53 moves towards the first exhaust fan 51, one end of the movable seat 53 enters the groove 64 on the connecting block 61, and under the action of the elastic force of the first spring 63, the stopper 62 tends to move outwards, when the movable seat moves to a limit position, the stopper 62 and the clamping groove 65 in the groove 64 are axially positioned on the same plane, and the connecting block 61 rotates, so that when the stopper 62 and the clamping groove 65 are overlapped in the circumferential direction, the stopper 62 moves towards the inside of the clamping groove 65 under the action of the elastic force of the spring 63, so that part of the stopper 62 enters the clamping groove 65, and the stopper 62 limits the rotation between the connecting block 61 and the movable seat 53, and further, the torque force on the first fan 51 can be transmitted to the movable seat 53, further, the second exhaust fan 52 is rotated, so that the speed of the gas blown out by the first exhaust fan 51 is faster; the speed of the airflow formed by the exhaust port 33 is higher, so that the acting force of the air blown out by the exhaust fan 51 on the rainwater entering the exhaust port 33 is higher, the difficulty of the rainwater entering the shell 1 through the exhaust port 33 is increased, the drying of the internal environment of the power distribution cabinet is ensured, the damage of the electrical equipment in the power distribution cabinet caused by the overlarge humidity in the rainwater and the air is prevented, and the use safety of the power distribution cabinet is ensured; thereby ensuring the safety of the electric equipment connected with the power distribution cabinet; meanwhile, in the whole clamping process, the first exhaust fan 51 is always in a rotating state, so that dynamic clamping is realized, airflow is always arranged at the position of the exhaust port 33, rainwater is prevented from entering in the clamping process, and the rainproof effect of the power distribution cabinet is further enhanced;

the two ends of the movable seat 53 inside the coil 77 are made to be magnetic, and by controlling the direction of the current, the magnetic pole of one end of the movable seat 53 close to the first magnet is different from the magnetic pole of one end of the first magnet close to the movable seat 53, so that the first magnet 71 and the movable seat 53 are attracted to each other, and the first magnet attracts the movable seat 53 to move towards the first exhaust fan 51; meanwhile, because the magnetism of the ends of the first magnet 71 and the second magnet 72 close to each other is the same, when the first magnet 71 and the movable seat 53 attract each other, the opposite magnetism between the second magnet 72 and the movable seat 53 is the same, and therefore the magnets repel each other, the movable seat 53 is further pushed to move towards the first exhaust fan 51, and further the clamping mechanism 6 is clamped, so that the first exhaust fan 51 can drive the second exhaust fan 52 to rotate, and further the speed of the gas blown out by the first exhaust fan 51 is higher;
