Surely it is connected with snorkel 13, the port of snorkel 13 is communicated with the bottom of cavity 12, and the middle section of cavity 12 is fixedly connected with limit
Block 20, the inner wall of cavity 12 slidably connect piston 19, and piston 19 is located at the top of limited block 20, and the top of cavity 12 is fixed to be connected
It is connected to spring 22, the other end of spring 22 is fixedly connected with baffle 23, and baffle 23 and the inner wall of cavity 12 are slidably connected, supporting leg 1
Lower end offer first row stomata 17, the middle section of first row stomata 17 is through offering sliding slot 18, the inner wall sliding of sliding slot 18
It is connected with link block 16, the bottom of link block 16 is fixedly connected with Expandable strip 15, and the bottom side of Expandable strip 15 is provided with water suction
Hole 14, suction hole 14 are provided with the surface of supporting leg 1, and the upper end of supporting leg 1 offers second row stomata 24, the gas of second row stomata 24
Mouth is fixedly connected with exhaust pipe 25.
Wherein, air intake duct 6 is communicated with the inside of distribution cabinet body 7, and fan 8 is dried to the inside of distribution cabinet body 7, then
Air pump 5 and fan 8 can form cross-ventilation, improve the heat dissipation effect inside distribution cabinet body 7.
Wherein, Expandable strip 15 is formed by the inorganic water uptake expansion material of macromolecule and compounding rubber, when Expandable strip 15 absorbs
It can then expand afterwards, then Expandable strip 15 can push link block 16 to be sealed first row stomata 17, when Expandable strip 15 is dry
It can then restore to the original state afterwards.
Wherein, the height limitation of piston 9 is that, when piston 9 is contacted with baffle 23, piston 9 can be by second row stomata 24
Sealing, guarantees that air will not be discharged from second row stomata 24 with this, when baffle 23 and piston 9 are moved to 12 top of cavity,
Piston 9 can be removed from the opening of the second air-discharging 24, and when 12 air pressure inside of cavity is sufficiently large, air pressure pushes piston 9, gear
Plate 23 is by spring 22 toward that can compress, and then second row stomata 24 carries out pressure release, while continuing to keep the convection current of air pump 5 and fan 8,
For distribution cabinet heat radiation.
Wherein, the height limitation of limited block 20 is that limited block 20 is higher than first row stomata 17, can be to avoid piston 19 with this
First row stomata 17 or snorkel 13 are sealed.
Wherein, the elastic force of spring 22 is limited to, and when cylinder 3 is reached longest state by air pressure inside, spring 22 just can quilt
Air pressure inside cavity 12, which squeezes, to be moved, and can make 3 variety of priority driven of cylinder with this, so that distribution cabinet body 7 increases, when cylinder 3 is stretched
When to longest, air pressure inside also will continue to increase, and as a result when air pressure inside overcomes the elastic force of spring 22 enough, piston 19 is then
It can be pushed to the top of cavity 12, so that second row stomata 24 carries out pressure release.
Wherein, the opening direction of exhaust pipe 25 be straight down, when supporting leg 1 is entirely flooded by water, vertical exhaust pipe
25 can prevent water from flowing backward into cavity 12, as long as and second row stomata 24 is kept to be constantly in exhaust condition, water just will not
Flow backward into cavity 12.
Wherein, the extraction flow of first row stomata 17 is greater than the flow of snorkel 13, works as link block 16 from first row with this
When being detached from stomata 17, gas can be quickly discharged from first row stomata 17, and air pressure inside can rapid decrease, thus distribution
Cabinet body 7 can then decline because of dead weight, and the extraction flow of second row stomata 24 is less than the flow of snorkel 13, can be made with this
Second row stomata 24 is while pressure release, it is ensured that 12 air pressure inside of cavity is in a stable state, avoids distribution cabinet body 7
Occurs the situation that teetertotters after being raised.
Wherein, 14 height limitation of suction hole be lower than first row stomata 17, can be preferentially by link block with this Expandable strip 15
16 are plugged on first row stomata 17, and water is avoided to flow backward from first row stomata 17 into cavity 12.
In using the present invention: when encountering flood, Expandable strip 15 is absorbed water by suction hole 14, and then Expandable strip 15 absorbs water
Expansion pusher dynamic sealing pin 16 up moves, so that link block 16 seals first row stomata 17, it is then normally opened from being constantly in
The gas that the air pump 5 of state is sent can not then be discharged from first row stomata 17, and then air pressure pushes piston 19 up to move, and work as work
When plug 19 is moved to the top of the opening of connecting tube 2,12 internal gas of cavity can then enter inside cylinder 3 along connecting tube 2, connect
Air pressure pusher cylinder 2 extend, and cylinder 2 pushes lifting chain 10 to close up toward centre again, and then lifting chain 10 can be by distribution
Cabinet body 7 is increased, and after flood is decorporated, Expandable strip 15 can then be dried and be restored to the original state, and then link block 16 falls meeting again
Original place, and the gas inside cavity 12 then will continue to be discharged by first row stomata 17, as the air pressure inside supporting leg 1 reduces, match
Electric cabinet body 7 automatic lifting of power distribution cabinet may be implemented with this, while can occur in water to avoid circuit because self gravity declines
The case where short circuit or damage, and when in use, when air is blown into distribution 7 inside of cabinet body by fan 8, air pump 5 passes through air intake duct 6
Hot gas is siphoned away, and is discharged by first row stomata 17, then forms cross-ventilation inside distribution cabinet body 7, improves distribution cabinet body 7
Internal heat dissipation effect can also improve heat dissipation effect with this power distribution cabinet when prevention is inundated with flood.
