plate 48 moves downwards, negative pressure is generated inside the metal heat exchange plate 41 above the push plate 48 and is communicated with the bottom of the water storage tank 44 through the water guide opening 46 and the water guide pipe 42, so that the cooling liquid inside the water storage tank 44 is pumped into the metal heat exchange plate 41 above the push plate 48 under the action of the negative pressure, the heat inside the metal heat exchange plate 41 is absorbed, the memory alloy strip 45 is cooled, the memory alloy strip 45 is restored to the initial state, the memory alloy strip 45 is contracted again and is driven to move upwards, so that the gas cooled inside the water storage tank 44 enters the metal heat exchange plate 41 below the push plate 48 again under the action of the negative pressure, and meanwhile the cooling liquid above the push plate 48 enters the water storage tank 44 again along with the water guide opening 46 and the water guide pipe 42 for cooling, thereby repeated heat transfer reduces the inside temperature of cubical switchboard body 6, is convenient for dispel the heat to cubical switchboard body 6 inside, and convenient to use buries water storage box 44 underground simultaneously, because underground temperature is lower, is convenient for accelerate the cooling to coolant liquid and gaseous.
From the above, when the accumulated water rises, the top of the connecting plate 19 is in contact with the second point contact switch 14 under the buoyancy action of the accumulated water, the first forward and reverse rotation motor 5 is electrified to drive the square expansion rod 4 and the screw rod 3 to rotate clockwise to lift the switch cabinet body 6, so that the accumulated water is prevented from entering the switch cabinet body 6, when the accumulated water falls, the extrusion plate 18 at the bottom of the connecting plate 19 is abutted against the first point contact switch 13, the first forward and reverse rotation motor 5 rotates anticlockwise to drive the switch cabinet body 6 to move downwards, so that the height of the switch cabinet body 6 is automatically adjusted according to the increase and decrease of the accumulated water, the switch cabinet body 6 is always positioned above the accumulated water, the accumulated water is further prevented from entering the switch cabinet body 6 to cause water soaking and short circuit of the equipment, and when the water level of the accumulated water reaches the position of the sealing shell 35, under the effect of ponding buoyancy, promote buoyancy board 39 and float on, and move to the centre through the closing plate 22 that 31 transmission effects of second positive and negative motor down drove the upper and lower both ends of spread groove 21, seal bleeder vent 23, improve the sealed effect of bleeder vent 23 position department, further prevent that ponding from lasting the inside that rises entering cubical switchboard body 6 from causing the damage to equipment, simultaneously can be through the in-process of memory alloy strip 45 intensification cooling, make it take place deformation, heat transfer is carried out to cubical switchboard body 6 inside, be convenient for dispel the heat to cubical switchboard body 6 inside, high durability and convenient use.
It should be understood by those skilled in the art that the above embodiments are only for illustrating the present invention and are not to be used as a limitation of the present invention, and that changes and modifications to the above embodiments are within the scope of the claims of the present invention as long as they are within the spirit and scope of the present invention.
