[0019] The present invention will be described in detail below with reference to the accompanying drawings. Example

[0020] The following is combined with Figure 1-4The present embodiment describes an intelligent fireproof and dustproof power distribution cabinet, comprising: a cabinet body 1, a cabinet door 2 is hingedly connected to one side wall of the cabinet body 1, an air duct 3 is opened on the side wall of the cabinet body 1, the outside of the air duct 3 is covered with a one-way sealing sheet 4, the upper part of the one-way sealing sheet 4 is hingedly connected to the outer surface of the side wall of the cabinet body 1, an air intake pump and a vacuum pump are connected to the side wall of the cabinet body 1 through an air hole 5, the air intake pump and the vacuum pump are turned on and off mutually, a fire light and a smoke sensor are arranged in the cabinet body 1, and the fire light and the smoke sensor can control the opening and closing of the air intake pump and the vacuum pump respectively through a controller;

[0021] When no fire occurs, the air intake pump is normally open, and the air intake pump injects air into the cabinet 1 through the air hole 5 and discharges it through the air duct 3. During the air injection process, the dust inside the cabinet 1 is discharged to complete the dust removal. When a fire occurs, the fire and smoke sensor detects the fire and sends a signal to the controller. The controller controls the air intake pump to be turned off and the vacuum pump to be turned on. The vacuum pump extracts air from the cabinet 1 through the air hole 5, and the one-way sealing sheet 4 is buckled on the outer surface of the side wall of the cabinet 1 to seal the cabinet 1. A vacuum environment is formed in the cabinet 1. After losing oxygen to support combustion, the flame goes out, and the fire is extinguished without affecting the power distribution module.

[0022] The airway 3 is connected to the outside with an air outlet pipe 6, the air outlet pipe 6 is connected to the outer surface of the air outlet pipe 6, the one-way sealing sheet 4 is located in the air outlet pipe 6, and the outer end of the air outlet pipe 6 is sleeved with a cloth bag;

[0023] The gas is discharged into the bag through the air duct 3 and the outlet pipe 6, and the bag collects the dust.

[0024] There are multiple air holes 5, all of which are connected to the branch pipe 7, the branch pipe 7 is connected to the main pipe 8, the main pipe 8 is connected to the middle of the intake and exhaust pipe 9, the two ends of the intake and exhaust pipe 9 are respectively connected to the intake pump 10 and the vacuum pump 11, the end of the intake and exhaust pipe 9 at the vacuum pump 11 is provided with a one-way valve that can only exhaust, and the end of the intake and exhaust pipe 9 at the intake pump 10 is provided with a one-way valve that can only intake;

[0025] When the air intake pump 10 is working, the exhaust gas enters the air intake and exhaust pipe 9, and the exhausted gas is blocked by the one-way valve at the end of the vacuum pump 11 in the air intake and exhaust pipe 9, enters the branch pipe 7 through the main pipe 8, and is dispersed directly to various parts of the cabinet 1 through the branch pipe 7, so that dust will not be adsorbed in various parts of the cabinet 1, and is discharged through the air duct 3. When the vacuum pump is working, it inhales air through the air intake and exhaust pipe 9. Due to the obstruction of the one-way valve at the end of the air intake pump 10, air can only be exhausted through the main pipe 8 and the branch pipe 7 through the cabinet 1 to complete the vacuum pumping.

[0026] The air duct 3 and the air hole 5 are arranged on two opposite side walls of the cabinet 1, and the air duct 3 is provided with a plurality of air ducts and is staggered with the air holes 5;

[0027] The air discharged from the air hole 5 directly hits the inner wall of the cabinet 1, thereby driving the air flow in the cabinet 1 and carrying the dust out.
