7. A use method of a lock-free switch cabinet capable of automatically radiating heat comprises the following specific steps:
the first step is that when an electrician master is required to operate the infrared light projector and the infrared light receiver, the switch is closed, the infrared light projector and the infrared light receiver are powered off, and the infrared light projector and the infrared light receiver can approach the infrared light projector to operate; when the electrician leaves after finishing the operation, the switch is opened outside the stepping table, the infrared projector and the infrared light receiver are electrified, when a layman approaches the invention and steps on the stepping table, the human body can shield the infrared ray so that the infrared light receiver can not receive the light signal, the infrared light receiver sends a signal to enable the alarm flash lamp to work for warning, and when the layman leaves, the infrared receiver receives the light signal again, and the alarm flash lamp stops working;
secondly, when an electrician master is required to open the switch cabinet for operation, the circular handle is screwed by hands to enable the rectangular block to freely enter and exit the irregular groove, and at the moment, the switch cabinet door can be opened; when the operation is finished, the switch cabinet door is closed and the round handle is screwed, at the moment, the switch cabinet door is fixed, and a gap between the switch cabinet door and the switch cabinet is prevented from being generated by extruding the sealing rubber strip to enter dust, so that the first cavity is relatively closed;
thirdly, when the temperature in the first cavity is too high, the temperature of the first cavity expands through the heat conducting block to push the first sliding block to slide upwards until the first sliding block triggers the first sensor to start the fan and open the first ball valve, at the moment, air is discharged out of the first cavity through the first through hole after sequentially passing through the first filter screen, the fan, the cooling pipeline and the first cavity, the first cavity is cooled, when the temperature requirement is met, the first sliding block slides downwards due to mercury contraction, at the moment, the first sensor is reset to cut off the power of the fan, the first ball valve is closed, at the moment, the first through hole is closed to prevent dust and other impurities from entering the first cavity through the first through hole;
the fourth step is that the detachable dustproof device positioned in the cooling pipeline plays a role when the fan is electrified: when air flows through the cooling pipeline and the detachable dustproof device, the air sequentially passes through the second filter screen, the microporous material and the third filter screen and enters the first cavity after being purified, when the detachable filter block needs to be replaced, the annular slide block slides rightwards by a worker, the detachable filter block can be taken out at the moment, a new detachable filter block is put in, the left end face of the new detachable filter block is abutted to the left end face of the fixing groove, then the hand is released, the annular slide block moves leftwards by the elasticity of the spring, the second rectangular ring is abutted to the right end face of the detachable filter block, and resetting is completed.
