Detailed Description
The following description of the embodiments of the present application will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present application, but not all embodiments.
In the description of the present application, it should be understood that the terms "upper," "lower," "front," "rear," "left," "right," "top," "bottom," "inner," "outer," and the like indicate or are based on the orientation or positional relationship shown in the drawings, merely to facilitate description of the present application and to simplify the description, and do not indicate or imply that the devices or elements referred to must have a specific orientation, be configured and operated in a specific orientation, and thus should not be construed as limiting the present application.
Embodiment one:
referring to fig. 1, a temperature-control moisture-proof buried transformer substation comprises a transformer box 1 buried underground, wherein an outer box body 2 is installed at the upper end of the transformer box 1, a plurality of ventilation openings 21 are formed in the side wall of the outer box body 2, a partition plate 3 is embedded in the transformer box 1, through holes 31 are formed in the side wall of the partition plate 3, as shown in fig. 1, the through holes 31 are located on the upper side part of the partition plate 3, two opposite side walls of the transformer box 1 are fixedly connected with air extraction boxes 4, a one-way air inlet pipe 5 and a one-way air outlet pipe 6 which are communicated with the inside of the air extraction boxes 4 are respectively arranged on the opposite side walls of the air extraction boxes 4, one-way air inlet pipe 5 is communicated with the inside of the outer box body 2, one-way air outlet pipe 6 is communicated with the inside of the outer box body 2, and an air extraction device which enables the air extraction boxes 4 to extract air is installed in the outer box body 2.
As shown in fig. 1, on the left side of the partition plate 3, a unidirectional air inlet pipe 5 and a unidirectional air outlet pipe 6 are respectively disposed at the upper end and the lower end of the air extraction box 4; and on the right side of the partition plate 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 extraction box 4. Further, the unidirectional air inlet pipe 5 only allows air to flow from the unidirectional air inlet pipe 5 to the air extraction box 4, and the unidirectional air outlet pipe 6 only allows air to flow from the air extraction box 4 to the unidirectional air outlet pipe 6, and when the unidirectional air inlet pipe is actually installed, a unidirectional valve is installed in a pipeline.
The air extractor comprises a wind wheel 10 which is rotationally connected to the inner bottom of the outer box body 2, one blade of the wind wheel 10 is made of magnetic materials, specifically, the blade of the wind wheel 10 is in a cup shape, an iron sheet 7 is fixedly connected to the side wall of the air extractor 4, each air extractor 4 is embedded with a telescopic air bag 8, and the two telescopic air bags 8 are communicated through a guide pipe 9.
When the device is used, when air flow in the horizontal direction is blown, the air vent 21 is extruded into the outer box body 2 and pushes the wind wheel 10 to rotate, the magnetic blades on the wind wheel 10 sequentially sweep over the two iron sheets 7, so that the iron sheets 7 can be attracted to move towards the magnetic blades, the outer wall of the air extraction box 4 is pulled to enable the air extraction box 4 to bulge, and when the magnetic blades leave, the air extraction box 4 contracts and recovers under the action of self elasticity. Therefore, during the continuous rotation of the wind wheel 10, the two air extraction boxes 4 are continuously bulged and contracted. Taking fig. 1 as an example, when the right air extraction box 4 bulges, the telescopic air bag 8 in the right air extraction box can be lengthened, and the air in the left telescopic air bag 8 is extracted, so that the left telescopic air bag 8 is contracted, and the left air extraction box 4 is also pulled to be contracted, therefore, when the wind wheel 10 rotates, the two air extraction boxes 4 always keep a drum-contracted state, and when the left air extraction box 4 bulges, fresh cold air on the ground can be extracted into the air extraction boxes 4 through the unidirectional air inlet pipe 5.
When the left air extraction box 4 is contracted, the sucked cold air is discharged to the left side of the partition plate 3 along the unidirectional air outlet pipe 6, meanwhile, when the right air extraction box 4 is bulged, the air on the right side of the partition plate 3 can be sucked into the left air extraction box, and when the right air extraction box 4 is contracted, the internal air is discharged into the outer box body 2 along the unidirectional air outlet pipe 6. Therefore, in the process of rising the two air extraction boxes 4, fresh cold air on the ground can be continuously pumped into the power transformation box 1 and flows along the dotted line path in fig. 1, so that the pumped cold air flows in the power transformation box 1 along the serpentine route, the contact area and time between the cold air and the electrical equipment are greatly increased, and the heat generated by the electrical equipment can be rapidly and thoroughly emitted.
Embodiment two:
referring to fig. 2-3, unlike the first embodiment, the side wall of the transformer box 1 is provided with a plurality of hollow interlayers 11, adjacent hollow interlayers 11 are communicated through air pipes 14, a water absorbing plate 12 is embedded in the hollow interlayers 11, the side wall of the water absorbing plate 12 is provided with a plurality of capillary holes 13, and one of the unidirectional air outlet pipes 6 is communicated with the hollow interlayers 11. It should be noted that, through setting up capillary holes 13, both guaranteed that hot air can pass water absorbing plate 12, thoroughly dry water absorbing plate 12, capillary holes 13 can also effectively draw infiltration moisture simultaneously, improve water absorbing efficiency of water absorbing plate 12.
The inner wall of the outer box body 2 is fixedly connected with a gas storage bag 15, the gas inlet of the gas storage bag 15 is communicated with the interior of the adjacent hollow interlayer 11, and a pressure release valve 16 is arranged in the gas outlet of the gas storage bag 15. By arranging the pressure release valve 16, the air storage bag 15 can store sufficient air and has higher air pressure so as to ensure that the air has higher flow speed when being discharged, and the wind wheel 10 can be pushed to rotate.
Further, the air discharged into the air storage bag 15 is evaporated by being absorbed by moisture, so that the air temperature in the air storage bag 15 is low, and thus 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 box 1 is buried underground for a long time, the underground is moist, and moisture is inevitably permeated into the transformer box 1. In this embodiment, the moisture permeated around is absorbed by the water absorbing plate 12 in the hollow interlayer 11, so as to keep the inside of the transformer box 1 dry. In addition, referring to fig. 2, the right air extraction box 4 can continuously discharge the hot air after absorbing the heat in the box into the hollow interlayers 11 along the unidirectional air outlet pipe 6, and the hot air evaporates the moisture absorbed by the water absorbing plate 12 when flowing in each hollow interlayer 11, so that the water absorbing plate 12 keeps dry and can continuously absorb the permeated moisture.
The air discharged from the hollow interlayer 11 enters the air storage bag 15 for storage, the internal air pressure of the air storage bag 15 gradually rises along with the increase of the air quantity stored in the air storage bag 15, when the internal air pressure rises to the threshold value of the pressure relief valve 16, the pressure relief valve 16 is opened and ejects the stored air, and the wind wheel 10 is pushed to rotate, so that the air extractor is operated, and the heat dissipation efficiency of the transformer box 1 is promoted. Therefore, when the device is impacted by wind, air is continuously blown into the air storage bag 15 for storage, and after a certain amount of air is stored, the air is discharged, so that the device can have a good heat dissipation function even when no wind exists.
The foregoing is only a preferred embodiment of the present application, but the scope of the present application is not limited thereto, and any person skilled in the art, who is within the scope of the present application, should make equivalent substitutions or modifications according to the technical scheme of the present application and the inventive concept thereof, and should be covered by the scope of the present application.
