[0022] Specifically, Figure 1 , Figure 2 and Figure 4 As shown, the rotation of the output end of the micro motor 20 can drive the screw rod 11 to rotate. Since a second slider 12 is provided on the outer side of the screw rod 11 through a threaded engagement sleeve, when the screw rod 11 rotates, the second slider 12 will slide along the installation direction of the screw rod 11. Since the top end of the second slider 12 extends out of the interior of the installation groove 10, and a bottom plate 14 is installed on the top end of the second slider 12, and an equipment mounting frame 17 is installed on the top of the bottom plate 14, therefore, by controlling the movement of the second slider 12, the equipment mounting frame 17 installed on the top of the bottom plate 14 can be moved out of the cabinet 1, so that it is convenient for the operator to install the power distribution equipment above the equipment mounting frame 17, avoid being limited by the internal space of the cabinet 1 during the installation process, and improve the installation speed. After the power distribution equipment is installed above the equipment mounting frame 17, the equipment mounting frame 17 and the power distribution equipment are moved into the cabinet 1 together with the power distribution equipment through the rotation of the output end of the micro motor 20 for use.

[0023] When the bottom plate 14 moves inside the cabinet 1 , the first sliding blocks 9 installed on both sides of the bottom of the bottom plate 14 will slide along the installation direction of the supporting slide rods 13 , thereby ensuring the stability of the bottom plate 14 during movement.

[0024] Embodiment 2: Four foot pads 8 are installed at the bottom of the cabinet 1, and the four foot pads 8 are respectively located at the four corners of the bottom of the cabinet 1, an empty slot 4 is opened inside one side of the cabinet 1, and an installation port 5 is opened on one side of the empty slot 4, a sealing plate 7 is movably installed inside the empty slot 4, and the sealing plate 7 and the installation port 5 are sealed and connected by a sealing gasket, a plurality of multi-stage filter screens 19 are equidistantly installed on one side of the sealing plate 7, and a connecting plate 18 is installed at one end of the multi-stage filter screen 19, an electric air intake fan 3 is installed on one side of the cabinet 1, and a first filter screen 2 is installed on one side of the electric air intake fan 3, the electric air intake fan 3 is connected with the inside of the empty slot 4, an electric exhaust fan 15 is installed inside one side of the cabinet 1, and the two sides of the electric exhaust fan 15 are respectively connected with the inside of the cabinet 1 and the outside, a second filter screen 16 is installed on one side of the electric exhaust fan 15, a plurality of ventilation slots 6 are equidistantly opened on one side of the cabinet 1, and the ventilation slots 6 are connected with the inside of the empty slot 4.

[0025] Specifically, Figure 1 and Figure 3 As shown, the four foot pads 8 installed at the bottom of the cabinet 1 can make the entire cabinet 1 stably placed on the ground, and the electric inlet fan 3 installed on one side of the cabinet 1 can drive the outside air to enter the inside of the empty slot 4 through the ventilation slot 6, and then enter the inside of the cabinet 1, and the high-temperature gas generated inside the cabinet 1 can be discharged from the inside of the cabinet 1 by the rotation of the electric exhaust fan 15. Since a plurality of multi-stage filters 19 are installed inside the empty slot 4, the dust and impurities contained in the outside air can be filtered out multiple times by the plurality of multi-stage filters 19, thereby ensuring that the air entering the cabinet 1 The air outside does not contain pollutants, ensuring that the power distribution equipment inside the cabinet 1 will not be polluted. Since the two ends of the multi-stage filter 19 are respectively installed with a sealing plate 7 and a connecting plate 18, and the sealing plate 7 is sealed and connected to the installation port 5 opened on one side of the empty slot 4, the multiple multi-stage filters 19 can be completely drawn out from the inside of the empty slot 4 through the sealing plate 7, so as to facilitate cleaning and replacement. The electric inlet fan 3 and the electric exhaust fan 15 can speed up the circulation speed of the air inside the cabinet 1, thereby improving the heat dissipation effect of the cabinet 1 and improving the working efficiency of the power distribution equipment inside the cabinet 1.

[0026] Working principle: When in use, the rotation of the output end of the micro motor 20 can drive the screw rod 11 to rotate. When the screw rod 11 rotates, the second slider 12 will slide along the installation direction of the screw rod 11. By controlling the movement of the second slider 12, the equipment mounting frame 17 installed on the top of the bottom plate 14 can be moved out of the cabinet 1, so that it is convenient for operators to install the power distribution equipment above the equipment mounting frame 17, avoiding the limitation of the internal space of the cabinet 1 during the installation process, and improving the installation speed. After the power distribution equipment is installed above the equipment mounting frame 17, the output end of the micro motor 20 is used to drive the screw rod 11 to rotate. The rotation of the output end can move the equipment mounting frame 17 together with the power distribution equipment into the cabinet 1 for use. Then, the electric inlet fan 3 installed on one side of the cabinet 1 can rotate to drive the outside air to enter the empty slot 4 through the air vent 6 and then enter the cabinet 1. The high-temperature gas generated inside the cabinet 1 can be discharged from the cabinet 1 by the rotation of the electric exhaust fan 15. The electric inlet fan 3 and the electric exhaust fan 15 can speed up the circulation of air inside the cabinet 1, thereby improving the heat dissipation effect of the cabinet 1 and improving the working efficiency of the power distribution equipment inside the cabinet 1.
