DETAILED DESCRIPTION

[0024] The utility model will now be further described in detail with reference to the accompanying drawings.

[0025] See also Figure 1-2 As shown, in this embodiment, an electrical cabinet for a subway is provided, including a waterproof housing 1, a storage groove 101 is provided on the upper side of the waterproof housing 1, and adjustment grooves 102 are provided on both sides of the inner wall of the storage groove 101, and two motors 3 are installed on the lower side of the inner wall of the adjustment groove 102, and the output shaft of the motor 3 is fixedly connected with a screw 301;

[0026] An electrical cabinet 4 is slidably fitted in the storage groove 101, and two screw barrels 406 are provided on both sides of the electrical cabinet 4. The screw barrels 406 are threadedly fitted on the circumference of the screw rod 301. An equipment room 401 is provided on one side of the electrical cabinet 4. The equipment room 401 runs through the lower side of the electrical cabinet 4. A plurality of supporting mesh panels 5 are installed in the equipment room 401, and the plurality of supporting mesh panels 5 are equidistantly arranged in the vertical direction.

[0027] One aspect of the application of this embodiment is as follows: when in use, the equipment for controlling the important power system in the subway station is installed on the supporting mesh plate 5 inside the equipment room 401. When it is necessary to debug or maintain the equipment on the supporting mesh plate 5, the control motor 3 is operated to drive the screw rod 301 to rotate, and the screw rod 301 rotates to drive the screw barrel 406 to move upward, thereby driving the electrical cabinet 4 to slide upward out of the storage slot 101, so that the side opening of the equipment room 401 is exposed, which is convenient for debugging and maintenance of the equipment; after the debugging or maintenance is completed, the electrical cabinet 4 is re-stored in the waterproof shell 1 with reference to the above operation, and when underground water accumulates in the subway station, because the storage slot 101 of the waterproof shell 1 opens upward, the underground water enters the equipment room 401 and needs to completely submerge the waterproof shell 1. At the same time, more valuable equipment can be preferentially installed on the supporting mesh plate 5 located above. When the underground water is about to submerge the waterproof shell 1, the electrical cabinet 4 is driven to rise to the highest point.

[0028] An air inlet slot 402 connected to the equipment room 401 is provided on the upper side of the electrical cabinet 4 of the present embodiment, and a fan 6 is installed in the air inlet slot 402. When in use, the fan 6 draws external air into the equipment room 401 through the air inlet slot 402, and then the air passes through the supporting mesh plate 5 and enters the bottom of the storage slot 101 and the adjustment slot 102, so that the equipment on the supporting mesh plate 5 and the motor 3 in the adjustment slot 102 can be ventilated and cooled.

[0029] The electrical cabinet 4 of the present embodiment is provided with a mouth-shaped groove 403 located on the side of the air inlet groove 402, a plurality of first air holes 404 are provided on both sides of the electrical cabinet 4, and a plurality of second air holes 405 are provided on the four sides of the side, the first air holes 404 and the second air holes 405 are both connected with the mouth-shaped groove 403, the first air hole 404 is connected with the adjustment groove 102, the second air hole 405 is located above the waterproof shell 1, the air in the adjustment groove 102 enters the mouth-shaped groove 403 through the first air hole 404, and then the air in the mouth-shaped groove 403 is discharged from the electrical cabinet through the second air hole 405, through the opening of the air inlet groove 402 and the second air hole 405 are both located above the waterproof shell 1, thereby reducing the influence of the waterproof shell 1 on the air intake and exhaust of the electrical cabinet 4.

[0030] In the present embodiment, a dustproof plate 7 is installed in the air inlet groove 402, and an electric push rod 8 is installed below the dustproof plate 7. The electric push rod 8 is located above the fan 6, and the dustproof plate 7 is located on the peripheral side of the output shaft of the electric push rod 8. The output shaft of the electric push rod 8 is fixedly connected with a sealing cover plate 801, and the sealing cover plate 801 is located above the electrical cabinet 4. The dustproof plate 7 reduces the probability of dust and foreign matter entering the equipment room 401 through the air inlet groove 402. When the underground water accumulation is more serious, the electric push rod 8 is controlled to shrink and drive the sealing cover plate 801 to move downward to seal the opening of the air inlet groove 402. The motor 3 is controlled to work and drive the electrical cabinet 4 to move downward, so that the second air hole 405 is collected in the storage groove 101, so that the top of the electrical cabinet 4 is used to seal the opening of the storage groove 101. At the same time, a waterproof sealing strip can be installed at the corresponding position to improve the waterproof sealing effect.

[0031] In the air inlet slot 402 of the present embodiment, two drying boxes 9 are placed on the dustproof plate 7. The drying box 9 is located on the side of the output shaft of the electric push rod 8. The drying box 9 is a hollow plastic box structure filled with desiccant. Since subway stations are usually underground and the air humidity is relatively high, the drying box 9 is used to dehumidify the air entering the air inlet slot 402 to reduce the probability of affecting the service life of the equipment due to high air humidity. When the electrical cabinet is not in use, the sealing cover plate 801 is used to seal the opening of the air inlet slot 402 to reduce the probability of the drying box 9 absorbing moisture from the outside air.

[0032] The waterproof housing 1 of this embodiment is movably equipped with a plurality of universal wheels 2 at its lower side, and the waterproof housing 1 can be pushed, pulled and displaced by the universal wheels 2, thereby facilitating the adjustment and transfer of the position of the electrical cabinet.

[0033] The present invention is not limited to the above-mentioned implementation modes. Anyone should be aware of the structural changes made under the inspiration of the present invention. Any technical solution that is the same or similar to the present invention falls within the protection scope of the present invention. The technology, shape, and structure that are not described in detail in the present invention are all known technologies.
