Working principle: when the temperature of the transformer 3 is normal, the sealing plate motor 115 cannot be started, namely the sealing plates 109 are in a horizontal state, the water tank is closed, the monitoring motor II 203 and the monitoring motor I121 work normally, through continuous rotation of the monitoring motor II 203, power can be transmitted from the gear II 207 to the half gear II 210 or power is transmitted from the gear II 207 to the gear III 209, the gear III 209 is transmitted to the half gear I208, the gear II 207 and the half gear I208 cannot be meshed, the gear I206 is independently driven by the gear II 207 and the half gear I208 respectively, the gear I206 continuously rotates positively and negatively, the gear I206 enables the monitoring rod I106 to start to rotate positively and negatively, at the moment, the monitoring rod I106 and the monitoring rod II 107 start to rotate in a matched manner, at the moment, the camera 112 can continuously move along with the change of the junction points of the monitoring rod I106 and the monitoring rod II 107, so that the full-direction monitoring scanning of the transformer 3 is realized, and meanwhile, the camera 112 is provided with a fire detector, once the occurrence of a fire is detected, the fire detector is enabled, the monitoring rod I106 and the monitoring rod I106 can be changed, and the fire extinguisher 107 can be ejected from the fire extinguisher 107 through the monitoring rod 107; on the other hand, when the sealing plate motor 115 is not started, the swing rod 117 does not drive the connecting rod I116 to displace, under the condition that the connecting rod I116 does not displace, the adjusting rod 221 is caused to limit the rack I218 to move, namely the position of the gear ring 205 is in an initial state, at the moment, the power of the gear II 207 is converted through the transmission 212 to enable the crank I211 to rotate rapidly, the crank I211 drives the planetary gear 213 to revolve when rotating, the planetary gear 213 is meshed with the gear ring 205, the planetary gear 213 rotates, the crank II 214 drives the sliding block 215 to displace due to the rotation of the planetary gear 213, and at the moment, the gear ring 205 is in an initial position, the sliding block 215 only transversely slides on the sliding rail 216 and does not drive the sliding rail 216 to slide up and down on the main support 202, namely the rack II 224 does not drive the bevel ratchet group 220, and at the moment, the fan 219 does not blow into a water pool; when the temperature of the transformer 3 is slightly higher, the sealing plate motor 115 drives the swing rod 117 to rotate a certain angle, the higher the temperature of the transformer 3, the larger the rotation angle of the swing rod 117 is, because one swing rod 117 rotates a certain angle, all the swing rods 117 synchronously rotate through the connecting rods I116 and II 119, meanwhile, the connecting rod I116 descends a certain height, namely, the connecting rod I116 enables the rack I218 to extend out of the rack seat 217 through the adjusting rod 221, the gear ring 205 rotates a certain radian, the rotation of the gear ring 205 enables the displacement amplitude of the sliding block 215 on the sliding rail 216 to be smaller, but the sliding block 215 starts to drive the sliding rail 216 to slide up and down on the main support 202 by a small amplitude, when the sliding rail 216 slides up and down on the main support 202, the rack II 224 drives the bevel ratchet group 220, the bevel ratchet group 220 drives the fan blade 219 to rotate unidirectionally, so that the purpose that the fan blade 219 pumps air outside the water tank into the water tank is achieved, when the air flows into the cooling pipe 114 from the blower pipe 123, as the cooling pipe 114 is submerged by water at the bottom of the water tank outer unit 110, hot air can be primarily cooled in the cooling pipe 114 and then further cooled when the hot air emerges from the water tank 114, and only the cooled air can flow out of the water tank through a gap opened by rotation between the sealing plates 109, so that the transformer 3 is cooled, and hot air flows out from air holes at the top of the protective cover 103, and when the rotation amplitude of the swing rod 117 is smaller, the rack II 224 does not contact with the water pump head 2012, namely the monitoring rod I106 cannot spray water; when the temperature of the transformer 3 is too high, the rotation amplitude of the swing rod 117 is larger, the radian of the rotation of the gear ring 205 in a certain range is larger, so that the amplitude of the up-and-down sliding of the sliding rail 216 is larger, the amplitude of the sliding block 215 on the sliding rail 216 is smaller, when the sliding block 215 does not slide on the sliding rail 216, the crank II 214 drives the sliding block 215 to only slide the sliding rail 216 up and down on the main support 202, the movement amplitude of the sliding rail 216 reaches the maximum, so that the rotation speed of the fan blade 219 is accelerated by the rack II 224, namely, the blast volume is increased, meanwhile, the water pump pressure head 2012 is extruded when the rack II 224 is displaced downwards, the water pump spring 2013 is compressed after the water pump pressure head 2012 is pressed, due to the one-way valves on the water suction pipe 222 and the water drain pipe 223, therefore, the water stored in the water pump housing 2011 flows into the monitoring rod i 106 to be sprayed out through the drain pipe 223, when the rack ii 224 is displaced upwards, the water pump head 2012 is reset under the action of the water pump spring 2013, at the moment, the water in the water tank is pumped into the water pump housing 2011 through the water pumping pipe 222 to be stored, namely, the purpose of spraying the cooling component 0345 into the monitoring rod i 106 by the water pump 201 is realized through the displacement of the rack ii 224, the current transformer 3 is uniformly sprayed with water mist in all directions through the monitoring rod i 106, so that the current transformer 3 can be rapidly cooled, the normal operation of the current transformer 3 is ensured, the sprayed water-cooled current transformer 3 flows back into the water tank through a gap between the sealing plates 109, resources are saved by recycling, and the purpose of arranging the waterproof cover 113 is to prevent the water from flowing into the inner wall of the water tank inner unit 111 to influence the line safety and reduce the water source waste; when monitoring pole I106 water spray cools down to transformer 3, the cleaning cloth of monitoring pole I106 outer wall can clean observation window 104 equally, prevents that the water smoke on the observation window 104 from influencing personnel's the observation condition in observation window 104 department, and all closing plates 109 are in the effect of closing state under normal condition and prevent that the impurity from falling into the pond, the impurity just includes some smalls when maintenance personal overhauld transformer 3, and does benefit to spun water smoke backward flow reuse when closing plate 109 is opened.
