In embodiment 1, the box-type substation windproof mechanism comprises a prefabricated cavity 4, a box body 2 and a windproof door arranged on the box body 2 as shown in fig. 1 to 3. High-voltage switchgear, distribution transformer and the low-voltage distribution device that need in the transformer substation are in box 2, and this embodiment does not improve high-voltage switchgear, distribution transformer and low-voltage distribution device, only improves box-type transformer substation external structure, makes it more be applicable to the great area of wind, improves its wind resistance.

The prefabricated cavity 4 comprises a concrete bin 1, the concrete bin 1 is formed by pouring concrete, and the prefabricated cavity 4 is reserved in the concrete bin 1. A mounting seat 5 is arranged in the prefabricated cavity 4, a mounting cavity 12 is reserved below the mounting seat 5, and the mounting cavity 12 is located below the ground. Be equipped with cable duct 8 and earthing switch 7 in the installation cavity 12, cable duct 8 is used for the cable to pass through from, and earthing switch 7 is used for the effective ground connection of transformer substation, prevents electric leakage fault. The top end of the grounding switch 7 extends upwards and is used for connecting equipment in the transformer substation.

The channel-section steel has been erect to installation cavity 12 top, and the steel board has been laid to the channel-section steel top, and the last reservation of steel board has access hole 6 with installation cavity 12 intercommunication, installs the access door on the access hole 6, can enter into installation cavity 12 through the access door in, maintains earthing switch 7 and the cable in the installation cavity 12.

Be equipped with mount pad 5 on the steel board, box 2 assembles on mount pad 5, and simultaneously, box 2 sets up in prefabricated cavity 4, and for guaranteeing stability, box 2 and prefabricated cavity 4 pass through the concrete and connect.

The wind-proof door on the box body 2 comprises two door bodies 3, the two door bodies 3 are arranged on the box body 2 in a sliding mode, and the two door bodies 3 are close to or far away from each other along the length direction of the box body 2. And then when the door body 3 needs to be opened, only need to slide two door bodies 3 to both sides, push open can, for among the prior art, door body 3 adopts articulated mode with box 2, sliding connection's mode, and door body 3 is more prevent wind with being connected of box 2, and when the door body 3 was in the open mode, it was difficult to close again in the effect of wind.

In order to realize the sliding connection between the door body 3 and the box body 2, a guide rail 11 which is horizontally arranged is arranged on the box body 2, and the door body 3 is arranged in the guide rail 11 in a sliding way. A driving assembly is arranged above the guide rail 11 and drives the door body 3 to move along the guide rail 11.

Wherein, drive assembly includes gear 9, and gear 9 top and below all are equipped with rack 10, two rack 10 parallel arrangement. The gear 9 is respectively meshed with the two racks 10, and when the gear 9 rotates, the two racks 10 move in opposite directions under the action of the gear 9. The two door bodies 3 are respectively connected with the two racks 10, so that the racks 10 can drive the door bodies 3 to move when moving.

In this embodiment, the drive assembly further comprises a motor which drives the rotation of the gear 9. During operation, the motor rotates to drive the gear 9 to rotate, the gear 9 rotates to drive the two racks 10 to move in opposite directions, and the racks 10 drive the two door bodies 3 to move in opposite directions, so that the door bodies 3 are closed or opened.

In this embodiment, the motor is not shown in the figure, a switch of the motor may be provided on the concrete silo, and the motor may be started after the switch is turned on.

As for the power of motor, can adopt the electricity in the transformer substation, certainly in order to avoid the accident, also can set up the battery on the concrete storehouse, the battery be used for the motor power supply can, still can be for the motor power supply through the battery when taking place accident such as power failure like this to make the door body open or close.

The working process is as follows: at a set position, according to the size of the box body 2, prefabricating the concrete bin 1, wherein the prefabricated cavity 4 and the installation cavity 12 need to be reserved in the concrete bin 1, and a steel plate is paved above the installation cavity 12. Subsequently, transport box 2 in the prefabricated cavity 4 in the concrete storehouse 1, reuse concrete with box 2 and prefabricated cavity 4 connect can, improved box-type substation's stability, simultaneously, also can integral installation, the installation is quick, construction convenience. When box 2 is opened to needs, only need open the motor, the motor drives gear 9 and rotates to make two racks 10 keep away from each other, move extreme position until the door body 3, box 2 exposes completely, can maintain the interior device of box 2.

Embodiment 2, this embodiment is different from embodiment 1 in that: as shown in fig. 4, the door body 3 includes a first division 31 and a second division 32, the first division 31 is fixedly connected to the rack 10, and the second division 32 is hinged to the first division 31. When the door body 3 moves to the limit position, the second sub-body 32 can be exposed from the concrete bin 1, and the second sub-body 32 is bent relative to the first sub-body 31 for avoiding overlarge wind, so that the wind area is reduced, and therefore when power distribution equipment in the box body 2 needs to be maintained in windy weather, the door body 3 is prevented from being overlarge in wind area, and the door body 3 is prevented from being damaged.

For the stability that improves second branch body 32 after buckling, be equipped with magnet on the side of second branch body 32, the cooperation magnet is equipped with the iron wainscot on the lateral wall of concrete storehouse 1, magnet and iron wainscot attract under the magnetic force effect can each other.

Example 3, this example differs from example 2 in that: as shown in fig. 5 to 6, the top of the concrete bin 1 is a hollow structure connected with the prefabricated cavity 4, so that the top surface of the box body 2 can be exposed out of the concrete bin 1.

When the air-conditioning device is implemented, an interlayer 16 is arranged in the side wall of the box body 2, an air channel 15 is arranged in the interlayer 16, and the air channel 15 is spirally arranged around the box body 2. One end of the air channel 15 is an inlet 13, the other end is an outlet 14, and an exhaust fan is arranged on the outlet 14 of the air channel 15. When implementing, open the exhaust fan, the convection current air can follow import 13 and get into, flows along air channel 15 in intermediate layer 16, finally comes out from export 14, and then improves the heat dissipation in the box 2, avoids in the box 2 because of equipment generates heat too much, the too high problem of temperature in the box 2 that causes, has also solved the inconvenient problem of dusty area heat dissipation.

Meanwhile, through the embodiment, dust can be prevented from entering the box body 2, normal work of equipment in the box body 2 is guaranteed, and the dust collecting box is particularly suitable for windy and dusty areas.
