As shown in figures 1 to 4:
The invention provides a flood control lifting type power distribution cabinet, which comprises supporting legs 1, connecting pipes 2, cylinders 3, telescopic hoses 4, an air pump 5, an air suction pipe 6, a power distribution cabinet body 7, a fan 8, a cabinet body guide rail 9, a lifting hinge 10, a supporting leg guide rail 11, a cavity 12, an air feed pipe 13, a water suction hole 14, an expansion strip 15, a sealing pin 16, a first exhaust hole 17, a chute 18, a piston 19, a limiting block 20, a guide wheel 21, a spring 22, a baffle plate 23, a second exhaust hole 24 and an exhaust pipe 25, wherein the supporting leg guide rail 11 is fixedly connected above the supporting legs 1, the cylinders 3 are fixedly arranged at two ends of the supporting leg guide rail 11, the connecting pipes 2 are fixedly connected at the tail parts of the cylinders 3, the other ends of the connecting pipes 2 penetrate through the supporting legs 1 to be communicated with the upper ends of the cavities 12, the cavities 12 are arranged in the supporting legs, one end of the guide wheel 21 is rotatably connected with a lifting hinge 10, a cabinet guide rail 9 is connected above the lifting hinge 10 in a rolling manner, a distribution cabinet body 7 is fixedly connected above the cabinet guide rail 9, a fan 8 is arranged on one side surface of the distribution cabinet body 7, an air suction pipe 6 is fixedly connected on the other side surface of the distribution cabinet body 7, an air pump 5 is fixedly connected on the other end of the air suction pipe 6, the air pump 5 is fixedly connected on the side surface of the distribution cabinet body 7, an expansion hose 4 is fixedly connected at an air outlet of the air pump 5, an air supply pipe 13 is fixedly connected on the other end of the expansion hose 4, an air port of the air supply pipe 13 is communicated with the bottom of the cavity 12, a limiting block 20 is fixedly connected on the middle section of the cavity 12, a piston 19 is connected on the inner wall of the cavity 12 in a sliding manner, the, first exhaust hole 17 has been seted up to landing leg 1's lower extreme, and first exhaust hole 17's middle section runs through and has been seted up spout 18, and the inner wall sliding connection of spout 18 has seal pin 16, and seal pin 16's bottom fixedly connected with inflation strip 15, and bottom one side of inflation strip 15 is provided with water absorption hole 14, and water absorption hole 14 is seted up on landing leg 1's surface, and second exhaust hole 24, second exhaust hole 24's gas port fixedly connected with blast pipe 25 have been seted up to landing leg 1's upper end.
The air suction pipe 6 is communicated with the inside of the power distribution cabinet body 7, and the fan 8 blows air to the inside of the power distribution cabinet body 7, so that the air pump 5 and the fan 8 can form air convection, and the heat dissipation effect inside the power distribution cabinet body 7 is improved.
The expansion strip 15 is formed by mixing a polymer inorganic water-absorbing expansion material and rubber, and expands after being absorbed by the expansion strip 15, so that the expansion strip 15 can push the sealing pin 16 to seal the first exhaust hole 17, and the expansion strip 15 can recover to the original shape after being dried.
Wherein, the height restriction of piston 19 is, when piston 19 and baffle 23 contact, piston 19 can be sealed with second exhaust hole 24 to this guarantees that the air can not be discharged from second exhaust hole 24, when baffle 23 and piston 19 move to cavity 12 topmost, piston 19 can follow the opening part of second exhaust air 24 and remove, when the inside atmospheric pressure of cavity 12 was enough big, atmospheric pressure pushed piston 19, baffle 23 will compress spring 22, then second exhaust hole 24 carries out the pressure release, continue to keep air pump 5 and fan 8's convection current simultaneously, dispel the heat for the switch board.
The height of the stopper 20 is limited such that the stopper 20 is higher than the first exhaust hole 17, thereby preventing the piston 19 from sealing the first exhaust hole 17 or the air supply pipe 13.
The elastic force of the spring 22 is limited in that when the cylinder 3 is extended to the longest state by the internal air pressure, the spring 22 is pressed by the air pressure in the cavity 12, so that the cylinder 3 can be preferentially driven to enable the power distribution cabinet body 7 to be lifted, when the cylinder 3 is extended to the longest state, the internal air pressure can be continuously lifted, and even when the internal air pressure is enough to overcome the elastic force of the spring 22, the piston 19 can be pushed to the topmost part of the cavity 12, so that the second exhaust hole 24 is decompressed.
The opening direction of the exhaust pipe 25 is vertical downward, when the support leg 1 is completely submerged by water, the vertical exhaust pipe 25 can prevent the water from flowing back into the cavity 12, and the water cannot flow back into the cavity 12 as long as the second exhaust hole 24 is kept in an exhaust state all the time.
Wherein, the exhaust flow of first exhaust hole 17 is greater than the flow of blast pipe 13, with this when the seal pin 16 breaks away from in first exhaust hole 17, gaseous can be fast from first exhaust hole 17 discharge, and inside atmospheric pressure alright descend fast, thereby the distribution cabinet body 7 then can descend because of self dead weight, the exhaust flow of second exhaust hole 24 is less than the flow of blast pipe 13, with this can be so that second exhaust hole 24 is in the pressure release, can guarantee that the inside atmospheric pressure of cavity 12 is in a stable state, avoid the distribution cabinet body 7 to appear the circumstances of rocking from top to bottom after being lifted.
the height of the water suction hole 14 is limited to be lower than that of the first vent hole 17, so that the expansion strip 15 can be preferentially inserted on the first vent hole 17 to prevent water from flowing backwards into the cavity 12 from the first vent hole 17.
In the use of the invention: when flood occurs, the expansion strip 15 absorbs water through the water absorption hole 14, the expansion strip 15 absorbs water and expands to push the sealing pin 16 to move upwards, so that the sealing pin 16 seals the first exhaust hole 17, then the gas sent by the air pump 5 which is always in a normally open state cannot be exhausted from the first exhaust hole 17, so that the air pressure pushes the piston 19 to move upwards, when the piston 19 moves above the opening of the connecting pipe 2, the gas in the cavity 12 enters the cylinder 3 along the connecting pipe 2, then the air pressure pushes the cylinder 3 to extend, the cylinder 3 pushes the lifting hinge 10 to fold towards the middle, so that the lifting hinge 10 can lift the distribution cabinet body 7, when the flood is relieved, the expansion strip 15 is dried and restored to the original state, so that the sealing pin 16 falls again to be in the original position, the gas in the cavity 12 is continuously exhausted from the first exhaust hole 17, and the air pressure in the supporting leg 1 is reduced, distribution cabinet body 7 descends because of self gravity, with this automatic rising that can realize the switch board, can avoid the circuit to appear the condition of short circuit or damage in the aquatic simultaneously, and when using, fan 8 blows the air into distribution cabinet body 7 when inside, air pump 5 siphons away steam through breathing pipe 6, and discharge through first exhaust hole 17, then 7 inside formation air convection of distribution cabinet body, improve the radiating effect of 7 inside of distribution cabinet body, when so switch board is submerged by the flood in the prevention, can also improve the radiating effect.
