The first embodiment is as follows:

referring to fig. 1, a accuse temperature moisture-proof type buries formula transformer substation, including burying underground transformer box 1 underground, outer box 2 is installed to transformer box 1 upper end, a plurality of vents 21 have been seted up to the lateral wall of outer box 2, transformer box 1 embeds is equipped with baffle 3, through-hole 31 has been seted up to the lateral wall of baffle 3, as shown in fig. 1, through-hole 31 is located the upside part of baffle 3, two relative lateral walls of transformer box 1 all fixedly connected with take out gas box 4, two relative lateral walls of box 4 of taking out gas are equipped with respectively rather than inside communicating one-way intake pipe 5 and one-way outlet duct 6, one of them one-way intake pipe 5 and the inside intercommunication of outer box 2, one of them one-way outlet duct 6 and the inside intercommunication of outer box 2, install the air exhaust device that makes box 4 bleed out gas.

It should be noted that, as shown in fig. 1, on the left side of the partition board 3, a one-way air inlet pipe 5 and a one-way air outlet pipe 6 are respectively arranged at the upper end and the lower end of the air extracting box 4; and on the right side of the partition board 3, a one-way air inlet pipe 5 and a one-way air outlet pipe 6 are respectively arranged at the lower end and the upper end of the air exhaust box 4. Furthermore, the one-way air inlet pipe 5 only allows air to flow to the air pumping box 4 from the one-way air inlet pipe 5, the one-way air outlet pipe 6 only allows air to flow to the one-way air outlet pipe 6 from the air pumping box 4, and a one-way valve is installed in a pipeline during actual installation.

Air exhaust device is including rotating the wind wheel 10 of connecting the bottom in outer box 2, and one of them blade of wind wheel 10 adopts magnetic material to make, and is specific, and the blade of wind wheel 10 is the wind cup, and fixedly connected with iron sheet 7 on the lateral wall of box 4 of bleeding all inlays in every box 4 of bleeding and is equipped with flexible gasbag 8, and two flexible gasbags 8 communicate through pipe 9.

This device is in the use, when the air current of horizontal direction assaults, will be crowded into outer box 2 by vent 21 and promote wind wheel 10 to rotate, and two iron sheets 7 will be swept in proper order to the magnetic blade on the wind wheel 10, so can attract iron sheet 7 to move towards the magnetic blade direction to 4 outer walls of pulling box of bleeding make 4 bloated, leave the back as magnetic blade, then the box of bleeding 4 contracts the recovery under self elasticity effect. Therefore, during the continuous rotation of the wind wheel 10, the two air boxes 4 are continuously expanded and contracted. Taking fig. 1 as an example, when the right side air pumping box 4 is expanded, the inner telescopic air bag 8 can be lengthened, and the air in the left side telescopic air bag 8 is pumped away, so that the left side telescopic air bag 8 is contracted, and meanwhile, the left side air pumping box 4 is also pulled to be contracted, therefore, when the wind wheel 10 rotates, the two air pumping boxes 4 always keep a state of being expanded and contracted, and when the left side air pumping box 4 is expanded, the fresh cold air on the ground can be pumped into the air pumping box 4 through the one-way air inlet pipe 5.

And when the left side box 4 of bleeding contracts, then discharge the cold air of suction to the baffle 3 left side along one-way outlet duct 6, meanwhile, when the right side box 4 of bleeding swells, can be with the air suction on baffle 3 right side in it, when the box 4 of bleeding of right side contracts, then arrange inside air in outer box 2 along one-way outlet duct 6. Therefore, in the process of lifting the two air exhaust boxes 4, fresh cold air on the ground can be continuously sucked into the power transformation box 1 and flows along the dotted line path in fig. 1, so that the sucked cold air flows in the power transformation box 1 along the snake-shaped route, the contact area and time between the cold air and the electrical equipment are greatly increased, and heat generated by the electrical equipment can be rapidly and thoroughly dissipated.

Example two:

referring to fig. 2-3, a difference from the first embodiment is that a plurality of hollow interlayers 11 are disposed on a side wall of the power transformation box 1, adjacent hollow interlayers 11 are communicated through an air pipe 14, a water absorption plate 12 is embedded in the hollow interlayers 11, a plurality of capillary holes 13 are disposed on a side wall of the water absorption plate 12, and one of the unidirectional air outlet pipes 6 is communicated with the hollow interlayers 11. It should be noted that, by providing the capillary holes 13, it is ensured that the hot air can pass through the water absorption plate 12 to thoroughly dry the water absorption plate 12, and meanwhile, the capillary holes 13 can effectively absorb the permeated water, thereby improving the water absorption efficiency of the water absorption plate 12.

Fixedly connected with gas storage bag 15 on the inner wall of outer box 2, and the inside intercommunication of air inlet and adjacent cavity intermediate layer 11 of gas storage bag 15, install relief valve 16 in the air outlet of gas storage bag 15. Through the arrangement of the pressure relief valve 16, sufficient air can be stored in the air storage bag 15 and the air pressure is high, so that the air is discharged at a high flow speed, and the wind wheel 10 can be pushed to rotate.

Further, the heat of the air discharged into the air storage bag 15 is absorbed by the moisture and evaporated, so that the temperature of the air in the air storage bag 15 is low, and the air storage bag 15 can discharge cold air into the power transformation box 1 during air discharge without affecting the heat dissipation effect of the power transformation box 1.

Because the transformer case 1 is buried underground for a long time, the underground is moist, and the moisture is difficult to avoid permeating into the transformer case 1. In this embodiment, the water penetrating around the transformer tank 1 is absorbed by the water absorption plates 12 in the hollow interlayer 11, so as to keep the transformer tank dry. In addition, referring to fig. 2, the right pumping box 4 can continuously discharge the hot air after absorbing the heat in the box into the hollow interlayers 11 along the one-way air outlet pipe 6, and the hot air will evaporate the moisture absorbed by the water absorption plates 12 when flowing in each hollow interlayer 11, so that the water absorption plates 12 can keep dry and can continuously absorb the permeated moisture.

The air exhausted from the hollow interlayer 11 enters the air storage bag 15 to be stored, the internal air pressure of the air storage bag 15 gradually rises along with the increase of the amount of the stored air in the air storage bag, when the internal air pressure rises to the threshold value of the pressure release valve 16, the pressure release valve 16 is opened to spray the stored air, and the wind wheel 10 is pushed to rotate, so that the air extractor is operated to promote the heat dissipation efficiency of the power transformation box 1. Therefore, the device can continuously blow air into the air storage bag 15 for storage when wind attacks, and the air is discharged after being stored for a certain amount, so that the device can also have a good heat dissipation function when no wind exists.

The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art should be considered to be within the technical scope of the present invention, and the technical solutions and the inventive concepts thereof according to the present invention should be equivalent or changed within the scope of the present invention.
