[0025] The front surface of the box body 1 is movably connected to a movable door 2 via a hinge, and the front surface of the movable door 2 is provided with an observation window.

[0026] Through the above technical solution, the device can conveniently inspect the DC power supply body 9 through the setting of the movable door 2.

[0027] Exhaust fans 5 are fixedly installed at both upper and lower ends of the rear side of the box body 1, and heat dissipation grooves 4 are opened on both left and right sides of the box body 1. The inner cavity of the heat dissipation grooves 4 is fixedly connected to the dust filter 3.

[0028] Through the above technical solution, the gas in the box body 1 is discharged to the outside through the exhaust fan 5, and then the external gas is guided to enter the box body 1 for replenishment after filtering dust through the dust filter 3 in the heat dissipation groove 4, thereby realizing rapid heat dissipation of the DC power supply body 9.

[0029] There are multiple partitions 10 , and the distance between two adjacent partitions 10 is equal.

[0030] Through the above technical solution, through the provision of the partition 10, a DC power supply with multi-level redundant backup can be placed.

[0031] The limiting slide bar 14 is matched with the guide groove 16 , and the limiting slide bar 14 slides on the inner side of the guide groove 16 .

[0032] Through the above technical solution, the setting of the limiting slide bar 14 and the guide groove 16 ensures the smooth movement of the supporting plate 15.

[0033] There are multiple balls 13 , and the distance between two adjacent balls 13 is equal.

[0034] Through the above technical solution, the ball 13 is arranged to reduce the resistance of the supporting plate 15 during movement.

[0035] The limiting slider 12 is matched with the limiting sliding groove 17 , and the limiting slider 12 slides on the inner side of the limiting sliding groove 17 .

[0036] Through the above technical solution, the movement range of the supporting plate 15 can be limited by setting the limiting slider 12 and the limiting slot 17.

[0037] When in use, after the device is powered on through the external power socket, the exhaust fan 5 can exhaust the gas in the box body 1 to the outside, and then guide the external gas to enter the box body 1 after filtering the dust through the dust filter 3 in the heat dissipation groove 4, so as to achieve rapid heat dissipation of the DC power supply body 9. When the DC power supply body 9 needs to be inspected and maintained, the limit block 6 is pressed to retract into the positioning seat 7 and compress the spring 18, so that the limit block 6 gives up the blocking of the guide groove 16. Then, the limit slide bar 14 and the guide groove 16 are closed. With the cooperation of the ball 13, the support plate 15 can be driven to move smoothly outward through the pull plate 8. At the same time, the limit slider 12 slides on the inner side of the limit slide groove 17, thereby avoiding the support plate 15 from being separated from the top of the partition 10. When the support plate 15 moves to the outside of the box body 1, the DC power supply body 9 corresponding to the top can be taken out for inspection or replacement. After completion, the support plate 15 moves inward to reset, and then the limit block 6 is released to continue to block the guide groove 16, and finally the movable door 2 is closed.

[0038] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
