[0052] Embodiment 2:

[0053] This embodiment is based on the first embodiment: a locking mechanism 5 is provided at the bottom of a bracket 11; the locking mechanism 5 includes an L-shaped plate 51 fixed to the outer bottom of a bracket 11, two elastic springs 511 are fixedly connected to the L-shaped plate 51, one end of the two elastic springs 511 is fixed with an extrusion plate 512 that slides with the L-shaped plate 51, and three plug-in connecting rods 513 are fixed to the side of the extrusion plate 512 close to the wiring installation frame 2; a plug-in board 22 is fixed to the bottom of the wiring installation frame 2, and a plurality of interconnected plug-in holes are provided on the plug-in board 22, and the three plug-in connecting rods 513 are plug-in-matched with three adjacent plug-in holes.

[0054] Specifically, a horizontal pressure plate 514 is fixed to one side of the extrusion plate 512; the locking mechanism 5 also includes an extrusion side plate 52 that horizontally slides with the inner wall of the distribution cabinet body 1, and a threaded rod 521 that is threadedly rotated with the inner wall of the distribution cabinet body 1 is threadedly rotated on one side of the extrusion side plate 52.

[0055] Furthermore, a key insertion plate surface 54 is provided on the L-shaped plate 51 , a locking key 53 is inserted and matched with one side of the key insertion plate surface 54 , and a locking block is provided at one end of the locking key 53 .

[0056] The operation process of this embodiment is as follows: after the wiring installation frame 2 is horizontally moved to a suitable position, the locking key 53 is inserted into the key plugging plate surface 54, and the locking block provided at one end of the locking key 53 contacts and squeezes the extrusion plate 512 that slidably cooperates with the L-shaped plate 51, driving the extrusion plate 512 to move horizontally toward one side of the wiring installation frame 2, so that the two elastic springs 511 fixedly connected between the L-shaped plate 51 and the extrusion plate 512 are initially compressed, and the three plug-in connecting rods 513 fixed on one side of the extrusion plate 512 gradually engage with the plug-in holes on the plug-in plate 22, until the locking key 53 and the extrusion plate 512 are engaged as shown in FIG. Fig.15 When the wiring installation frame 2 is maintained, the three-pin connecting rod 513 is plugged and fixed with the plug-in board 22, so that the position of the wiring installation frame 2 is fixed, and the problem of shaking of the wiring installation frame 2 during maintenance is avoided; and after the maintenance of the lines in the wiring installation frame 2 is completed, the threaded rod 521 that is matched with the thread rotation on the inner wall of the distribution cabinet body 1 is rotated, and the extrusion side plate 52 that is matched with the thread rotation on the side surface of the threaded rod 521 is driven to move along the inner wall of the distribution cabinet body 1 toward the horizontal pressure plate 514 until the horizontal pressure plate 514 and the extrusion side plate 52 contact and squeeze each other, driving the extrusion plate 512 moves horizontally toward one side of the wiring installation frame 2, so that the two elastic springs 511 fixedly connected between the L-shaped plate 51 and the extrusion plate 512 are compressed for the second time. At this time, the locking key 53 should be pulled out in turn and the threaded rod 521 should be rotated in the opposite direction. Under the elastic force of the two elastic springs 511, the extrusion plate 512 is driven away from the wiring installation frame 2 until the three-plug connecting rod 513 fixed on one side of the extrusion plate 512 is gradually separated from the plug-in hole on the plug-in plate 22. At this time, the position of the wiring installation frame 2 is released and the position of the wiring installation frame 2 can be moved.

[0057] Embodiment three:

[0058] This embodiment is based on the second embodiment: a wire harness tube 23 is arranged at the bottom of the wiring installation frame 2; a herringbone water baffle 24 is arranged on the wiring installation frame 2; a downward suction fan 12 is arranged below the wiring installation frame 2 in the distribution cabinet body 1, and an arc-shaped water guide plate 13 is arranged between the downward suction fan 12 and the inner wall of the distribution cabinet body 1, and the arc-shaped water guide plate 13 and the bottom of the distribution cabinet body 1 form a water storage chamber, and the water storage chamber is connected to the outside through a drainage pipe 14.

[0059] Specifically, the wiring installation frame 2 has two relatively outer side surfaces horizontally slidably matched with a ventilation plate 6, and one side of the ventilation plate 6 has a plurality of external ventilation holes 64; the wiring installation frame 2 has a plurality of internal ventilation holes 25 on two relatively sides.

[0060] Furthermore, a lifting plate 61 is slidably engaged with one side of the breathable plate 6, and a rotating plate 62 is rotatably engaged with one side of the lifting plate 61. A buoyancy pad 63 is fixedly installed on the bottom of the lifting plate 61 below the arc-shaped water guide plate 13; a center rod 26 rotatably engaged with one end of the rotating plate 62 is fixed on both opposite outer sides of the wiring installation frame 2.

[0061] The operation process of this embodiment is as follows: the herringbone water baffle 24 arranged on the wiring installation frame 2 can guide the water leaking into the distribution cabinet body 1 to both sides, and the lower suction fan 12 arranged at the bottom of the distribution cabinet body 1 can absorb the water at the outer bottom of the wiring installation frame 2, thereby improving the dryness of the surface of the wiring installation frame 2 and preventing the wiring installation frame 2 from short-circuiting when it encounters water. At the same time, the arc-shaped water guide plate 13 arranged between the lower suction fan 12 and the inner wall of the distribution cabinet body 1 can make the water in the distribution cabinet flow along the arc-shaped water guide plate 13 and enter the bottom of the distribution cabinet body 1. The water stored in the water storage chamber formed by the arc-shaped water guide plate 13 and the bottom of the distribution cabinet body 1 is drained outward through the drain pipe 14; when the water level in the water storage chamber formed by the arc-shaped water guide plate 13 and the bottom of the distribution cabinet body 1 changes, it drives the floating water in the water storage chamber to flow outward. The buoyancy pad 63 moves up and down with the water level. When water leaks into the distribution cabinet body 1, through the rotation cooperation between one end of the rotating plate 62 and the center rod 26, and the rotation cooperation between the other end of the rotating plate 62 and the lifting plate 61, the lifting plate 61 fixed on the top of the buoyancy pad 63 is driven to move upward and horizontally away from the center rod 26, thereby achieving and realizing the horizontal movement of the air-permeable plate 6 relative to the wiring installation frame 2, from the alignment of the outer air holes 64 and the inner air holes 25 when there is no water leakage, to the reduction of the gap between the outer air holes 64 and the inner air holes 25 after water leakage, until there is no gap between the outer air holes 64 and the inner air holes 25 after the water level increases to a certain level, so that the wiring installation frame 2 can be cooled in a dry environment, thereby improving the cooling efficiency of the new intelligent distribution cabinet.
