In the invention, when the vacuum circuit breaker 2 needs to be installed, the moving plate 18 can be pushed upwards to drive the two rotating rods 22 to rotate at a certain angle while moving upwards, at the moment, the four supporting legs 19 at the bottom of the vacuum circuit breaker 2 can be placed at the tops of the four circular shells 16, then the moving handle 18 is pulled downwards to drive the two rotating rods 22 to move downwards, and simultaneously, the screw on the moving handle 18 can be synchronously driven to slide downwards in the chute, so that the two rotating rods 22 can rotate and reset while moving downwards, until the bottom ends of the protruding blocks 23 at the top ends of the two rotating rods 22 are tightly abutted against the top ends of the supporting legs 19, the positions of the supporting legs 19 are limited and fixed, fastening nuts are sleeved on the screw, the positions of the screw in the chute are limited and fixed, further, the positions of the moving handle 18 can be limited, so that the positions of the rotating rods 22 and the protruding blocks 23 can be fixed similarly, the vacuum circuit breaker 2 can be installed and fixed quickly, tools and the burden of workers can be further reduced, and the installation efficiency can be improved.
When birds stand near the vacuum circuit breaker 2 for rest in the using process of the vacuum circuit breaker 2, the driving motor 14 can be controlled to start through the remote controller, the screw rod 13 mounted at the output end of the driving motor 14 and the limiting rod 15 on the outer wall of the screw rod are driven to rotate, the rotating plate 4 is driven to be in a state of shaking up and down through a series of mechanisms, the bell 8 on the top of the rotating plate is impacted, the bell 8 can make a sound after being impacted, the birds near the vacuum circuit breaker 2 can be scared away, the vacuum circuit breaker 2 can be far away from the birds, and excrement is discharged onto an insulating pole on the top of the vacuum circuit breaker 2 when the birds rest near the vacuum circuit breaker 2, so that the operation of the vacuum circuit breaker 2 is influenced, and the service life of the vacuum circuit breaker 2 is prolonged.
The water tank 3 arranged at the top of the support 1 can be used for collecting and storing rainwater in the water tank 3 through the water inlet in rainy days, when the vacuum circuit breaker 2 needs to be cooled in sunny days, the driving motor 14 can be started through the remote controller again to drive the screw rod 13 and the limiting rod 15 at the output end of the driving motor to rotate until the limiting rod 15 rotates to the position below the inner top surface of the support 1, and the rotating plate 4 can automatically rotate downwards under the self gravity when the supporting effect of the limiting rod 15 is lost; and can drive the closing plate 30 rebound in the water tank 3 when the lead screw 13 rotates, the rainwater of storing in the water tank 3 can be discharged to the top of rotor plate 4 through drain pipe 31 to discharge downwards to fin 5 along the top of rotor plate 4, make fin 5 receive behind the rainwater washing can be more quick dispel the heat, and then accelerate fin 5 to vacuum circuit breaker 2's radiating effect.
Meanwhile, the rainwater can synchronously wash dust or other sundries at the top of the rotating plate 4 when passing through the top of the rotating plate 4, and flows downwards to the radiating fins 5 along the trend to wash the dust or sundries on the outer walls of the radiating fins 5, which are difficult to shake and remove, so that the cleaning effect of the radiating fins 5 is improved. And rotor plate 4 is the downward sloping state, but be located rotor plate 4 inside sliding plate 33 this moment can be automatic stretch out downwards from rectangular channel 35, and drive the baffle 34 of its bottom and rotate downwards and be vertical state, carry out the separation to the insulating utmost point post at vacuum circuit breaker 2 top, thereby can protect insulating utmost point post, make from the interior exhaust rainwater of drain pipe 31 on flowing downwards to radiating fin 5 along rotor plate 4's top, baffle 34 can block the rainwater that splashes, avoid the rainwater to splash to insulating utmost point post on, the problem that causes the influence to the work of insulating utmost point post appears.
And in cold winter, snow can be produced on the tops of the rotating plate 4 and the radiating fins 5 when the snow falls outdoors, in order to avoid excessive snow on the tops of the rotating plate 4 and the radiating fins 5, so that the limiting rod 15 and the radiating fins 5 bear large pressure, and the situation of deformation or even breakage occurs, the controllable driving motor 14 is started to drive the rotating plate 4 and the radiating fins 5 to synchronously shake up and down, so that the snow on the tops of the rotating plate 4 and the radiating fins 5 becomes loose under the shaking situation, until the limiting rod 15 rotates to the lower part of the inner top surface of the bracket 1, the rotating plate 4 does not limit downward rotation and then drives the radiating fins 5 to rotate downward together, so that the snow on the tops of the radiating fins 5 and the rotating plate 4 can slide down along the potential, the snow on the tops of the rotating plate 4 and the radiating fins 5 is conveniently cleaned, and the influence on the work of the radiating fins 5 and the rotating plate 4 is avoided.
