Detailed ways

The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention.

Referring to Figure 1-5, a draw-out low-voltage power distribution cabinet includes a cabinet body 1, one side of the cabinet body 1 is provided with a mounting hole 2, and one side of the mounting hole 2 is connected with a door panel 3 through hinge rotation, and it is convenient to open the door panel 3 The staff installs and maintains the interior of the cabinet 1 through the installation hole 2. Both ends of the cabinet 1 are provided with louver holes 11, which facilitate the entry of external airflow and play a role in heat dissipation. The lower end of the cabinet 1 is symmetrical Four groups of moving wheels 4 are installed, and the moving wheels 4 are convenient for staff to move the low-voltage power distribution cabinet.

The inside of the cabinet body 1 is fixedly equipped with a plurality of fixed plates 5, and the upper end of each fixed plate 5 is provided with an annular plate 6, and each annular plate 6 is fixedly connected with a handle 7. In order to facilitate the movement of the annular plate 6, the handle 7 is installed on the side wall of the annular plate 6 on the side close to the installation hole 2, and the two adjacent annular plates 6 are dislocated in sequence, and the inner wall of each annular plate 6 is symmetrically fixedly connected with a plurality of mounting plates 12, each Mounting plate 12 is provided with mounting holes, and some important parts are installed on mounting plate 12, such as disconnector, circuit breaker, etc. After the installation is completed, the space in the middle of annular plate 6 facilitates the circulation of airflow, so the external airflow can be Inflow through the removed louver hole 11, pass through the middle of the annular plate 6, and flow out from the louver hole 11 on the other side. The smooth airflow can effectively improve the heat dissipation effect, and the flowing airflow can carry the internal parts of the annular plate 6. The emitted heat, or blown heat, is exhausted from the cabinet 1.

The annular plate 6 and the fixed plate 5 are connected by a connecting mechanism, and the connecting mechanism includes a plurality of T-shaped chute 8 provided on the fixed plate 5, and the inside of each T-shaped chute 8 is provided with a slide plate 9, and the inside of each slide plate 9 The upper end is fixedly connected with a connecting plate 10, and the upper end of each connecting plate 10 extends out of a T-shaped chute 8 and is fixedly connected with the corresponding annular plate 6. The sliding plate 9 can slide in the T-shaped chute 8, and the handle 7 can When moving the ring plate 6, during installation and maintenance, the ring plate 6 on both sides of the parts that need to be installed and repaired can be pushed to the side away from the installation hole 2, thereby leaving a large operating space, which is convenient for the staff to check the inside of the ring plate 6. The parts on the mounting plate 12 are installed and repaired, and various personnel can install and maintain the parts on the mounting plate 12 from both sides, which further facilitates the staff, and it is not necessary to maintain the parts in one of the annular plates 6. It will affect other components in the annular plate 6, reducing interference and improving the effect of installation and maintenance.

The two ends of each slide plate 9 are all fixedly connected with flashboard 13, and all are provided with the slot 14 that matches with flashboard 13 on the inner wall of both ends of each T-shaped chute 8, and the inside of each slot 14 is provided with There is a clamping mechanism, and the clamping mechanism includes mounting grooves symmetrically opened on both sides of the slot 14, each mounting groove is provided with a clamping block 15, and the ends of two adjacent clamping blocks 15 that are far away from each other are fixedly connected There are strong springs 16, and the other end of each strong spring 16 is fixedly connected with the inner side wall of the mounting groove. When the inserting plate 13 is inserted into the corresponding slot 14, the clamping blocks 15 on both sides will The inserting plate 13 can be stably clamped, so that the sliding plate 9 is fixed, and the components on the mounting plate 12 are stabilized through the connecting plate 10 and the annular plate 6, so that the components are stable during operation, and it is also convenient for the staff to install and overhaul. Components also remain stable.
