a stay cord motor is fixedly arranged on the left wall of the detection block cavity, the right end face of the stay cord motor is in power connection with the left end face of the winding wheel shaft, the outer circular face of the winding wheel shaft is fixedly connected with a winding wheel, hinged plates which are vertically symmetrical and are positioned on the upper side and the lower side of the winding wheel are connected to the front wall and the rear wall of the detection block cavity in a sliding mode, a stay cord which is fixedly connected with the end face of one side, close to the hinged plates on the upper side and the lower side, of the outer circular face of the winding wheel is wound and accommodated, and spring seats which are vertically symmetrical and are positioned on the upper side and the lower side of the winding wheel shaft are fixedly connected to the left wall of the detection block cavity; the stay cord motor drives the winding wheel shaft to rotate so as to drive the winding wheel to rotate, the stay cord is loosened through the rotation of the winding wheel, the hinged plates on the upper side and the lower side are pushed to move towards the upper side and the lower side through the thrust of the telescopic spring, so that the extension range of the four hinged rods is increased, a circuit and a structure are detected in a circuit cavity, the circuit can be pushed and pushed up to be collected after the hinged rods are contacted with the circuit in the circuit cavity through the widening block, and the fan box is pushed to move rightwards to the circuit cavity through the pushing block through the continuous movement of the moving plate;
a telescopic spring is fixedly connected between the end surface of one side, far away from each other, of the upper spring seat and the lower spring seat and the end surface of one side, close to each other, of the upper hinge plate and the lower hinge plate, the end surface of one side, far away from each other, of the upper hinge plate and the lower hinge plate is hinged with a hinge rod, and one end, far away from each other, of the rear end surfaces of the upper hinge rod and the lower hinge rod is fixedly connected with a widening block; when the push rod is contacted with the structure in the circuit cavity or the circuit and can not move continuously rightwards, the push rod moves leftwards and overcomes the thrust of the induction spring to press the induction button, at the moment, the moving motor is closed and the moving plate is stopped to move continuously, simultaneously, the gear motor is started to drive the power shaft to rotate, the rotating driving gear is driven to rotate by the rotation of the power shaft, the rotating driving gear rotates through meshing transmission to drive the fixed gear block to rotate, so as to drive the fan box plate to rotate, the fan driving gear rotates through the rotation of the power shaft, the fan driving gear rotates through meshing transmission to drive the fan driven gear to rotate, the gear shaft is driven to rotate through the rotation of the fan driven gear, so as to drive the forward fan to rotate leftwards to generate wind power, and the dust in the circuit cavity is sucked in an omnibearing manner through the rotation of the fan box plate and the suction of the side fans on the upper side and the lower side and the forward fan, at the moment, dust in the circuit cavity can enter the dust removing holes in the upper side and the lower side and is discharged outwards, the driving bevel gear is driven to rotate through the rotation of the gear shaft, the driven bevel gears in the upper side and the lower side are driven to rotate through meshing transmission through the rotation of the driving bevel gear, and therefore the fans on the upper side and the lower side are driven to rotate and rotate to be close to one side to generate wind power.
2. The heat dissipation device of claim 1, wherein a supporting plate for supporting the power box is fixedly connected to the left end surface of the circuit box.
