The integrated structure of the power switch cabinet according to claim 7, characterized in that: The drawer (2) is provided with a receiving groove (21), a sealing plate (22) corresponding to the passing groove (20) is slidably arranged in the receiving groove (21), and a return spring (23) is arranged between the sealing plate (22) and the receiving groove (21).

9. The integrated structure of the power switch cabinet according to claim 7, characterized in that: The buffer component comprises a fixed plate (24) arranged at the bottom of the drawer (2), an arc plate (25) and a second buffer seat (26) being coaxially hinged on the fixed plate (24), a first buffer seat (27) and a plurality of spring telescopic rods (28) being hinged on the arc plate (25), and free ends of the spring telescopic rods (28) being hinged to the fixed plate (24).

10. A construction method for an integrated structure of a power switch cabinet, for realizing the integrated structure of a power switch cabinet as claimed in claims 1 to 9, characterized in that: The following steps are involved: S1: selecting a drawer (2) to be inspected, and unlocking the drawer (2) using a locking member; S2: The output shaft of the lifting motor (16) is rotated forward, and the two lifting frames (15) are moved downward synchronously until the two connecting pieces correspond to the drawers (2) to be repaired, and the drawers (2) are limited by the connecting pieces, and the transverse frame (4) is driven to slide horizontally to the limit position, driving the drawers (2) to move horizontally together until they are separated from the cabinet body (1), and the sealing plate (22) is unblocked by the through slot (20), and the buffer member passes through the through slot (20); S3: The output shaft of the lifting motor (16) is rotated forward, and the two lifting frames (15) move downward together with the drawer (2) until the drawer (2) is close to the ground, and the sealing plate (22) slides and forces the return spring (23) to be squeezed, so that the drawer (2) is buffered by the buffer member; S4: The drawer (2) is released from the limit position through the two connecting pieces respectively, so that the output shaft of the lifting motor (16) is reversed, and the two lifting frames (15) rise synchronously, and maintenance can be carried out; S5: After the inspection is completed, the output shaft of the lifting motor (16) is rotated forward, and the two lifting frames (15) are moved downward synchronously until the two connecting parts correspond to the drawer (2) that has been inspected. The drawer (2) is limited by the connecting part, and the output shaft of the lifting motor (16) is reversed. The two lifting frames (15) rise together with the drawer (2). The reset spring (23) is reset to a natural state, and the sealing plate (22) slides in the opposite direction until the drawer (2) is at the same height as the initial installation position, driving the transverse frame (4) to slide horizontally to the initial position. The sealing plate (22) is blocked by the groove (20), and the drawer (2) is released from the limit through the two connecting parts respectively, so that the output shaft of the lifting motor (16) is reversed, and the two lifting frames (15) rise synchronously, and the drawer (2) is locked again by the locking member.
