[0026] The cabinet structure 1 is a removable switch cabinet. Corresponding through-hole plates 102 are installed on both sides of the cabinet according to the number of layers. The sealing cover 5 covering the through-hole plate 102 provides conditions for gas circulation for the transmission structure 2 and the air intake structure 4. The spacer layer 104 is the spacer section between each layer inside the cabinet.

[0027] The transmission structure 2 includes a first connection plate 201, a transmission tube 202, a second connection plate 203, a third connection plate 204, a pressure reducing valve 205, and an equalizing tube 206. The transmission tube 202 is connected to the first connection plate 201, and the second connection plate 203 is provided at the bottom end of the first connection plate 201. The third connection plate 204 is provided at the bottom end of the second connection plate 203. A pressure reducing valve 205 is installed on the transmission tube 202, and the end of the transmission tube 202 is connected to the equalizing tube 206. The transmission tube 202 is respectively connected to the second connection plate 203 and the third connection plate 204. The second connection plate 203 and the third connection plate 204 are fixedly installed in the spacer layer 104.

[0028] The transmission pipe 202 is divided into three sections, which correspond to the first connection plate 201, the second connection plate 203, and the third connection plate 204 respectively, so that the pressure reducing valves 205 on the three sections of the transmission pipe 202 can respectively transmit the gas transmission pressure of the transmission pipe 202, and the averaging pipe 206 connects the transmission pipe 202 with the docking port 303 of the fan structure 3, so that the transmission pressure of each transmission pipe 202 is as similar as possible, so that the sealing cover 5 corresponding to the transmission pipe 202 can maintain a certain negative pressure well, so that the gas through the partition layer inside the cabinet can circulate, and the gas can be introduced into the gas through the air intake structure 4, while conducting heat to the electrical components in the cabinet. Maintaining a certain negative pressure in the cabinet can effectively improve the sealing effect after the cabinet door 101 is closed, provide a certain pressure to the cabinet door 101, and make its connection sealing better.

The mounting base 301 is fixedly connected to the air intake cover 302, a docking port 303 is provided on one side of the air intake cover 302, the top of the air intake cover 302 is fixedly docked with the guide cover 304, the guide cover 304 is fixedly connected with a fixing block 305, the fixing block 305 is fixedly connected with a mounting slot, the high-speed motor 306 is fixedly installed in the mounting slot, the driving end of the high-speed motor 306 is connected with the fan blades 307, the top of the guide cover 304 is fixedly connected with the air outlet 308, and the air outlet 308 is rotatably connected with the rotating top cover 309.

[0030] The high-speed motor 306 of the fan structure 3 generates airflow by driving the fan blades 307, thereby generating a negative airflow pressure in the transmission pipe 202, and then introducing gas through the air intake structure 4. The air pressure control of the pressure reducing valve 205 can maintain a certain negative pressure environment in the cabinet. After the airflow is discharged through the air outlet 308, the airflow blows on the rotating top cover 309 with the air duct, thereby rotating the rotating top cover 309. At the same time, due to its umbrella-shaped design, it can blow away the dust on the top plate 103 to prevent dust accumulation on the top.

[0031] The air intake structure 4 includes an air intake strip 401 , a filter screen 402 , and a connecting cover 403 . The filter screen 402 is installed on the air intake strip 401 , and one end of the air intake strip 401 is connected to the connecting cover 403 through a sealing cover 5 .

[0032] An air port on one side of the air inlet strip 401 is installed with a filter 402, which can filter the introduced air well to prevent dust from entering. The connecting cover 403 is used to connect and dock with the sealing cover 5 on this side.

The sealing cover 5 covered on the through-hole plate 102 provides conditions for gas circulation for the transmission structure 2 and the air intake structure 4. The interval layer 104 is the interval section between each layer inside the cabinet. The transmission pipe 202 is divided into three sections, and the three sections correspond to the first through-hole plate 201, the second through-hole plate 203, and the third through-hole plate 204, so that the pressure reducing valve 205 on the three sections of the transmission pipe 202 can transmit the gas transmission pressure of the pipe 202 respectively, and the equalizing pipe 206 connects the transmission pipe 202 with the docking port 303 of the fan structure 3, so that the transmission pressure of each transmission pipe 202 is the same as much as possible, so that the sealing cover 5 corresponding to the transmission pipe 202 can maintain a certain negative pressure well, so that the gas through the partition layer inside the cabinet circulates, and the gas is introduced into the gas through the air intake structure 4, and at the same time The electrical components in the cabinet are heat-conducted at the same time, and maintaining a certain negative pressure in the cabinet can effectively improve the sealing effect of the cabinet door 101 after closing, and provide a certain pressure to the cabinet door 101 to make its connection sealing better. The high-speed motor 306 of the fan structure 3 generates airflow by driving the fan blades 307, so that the airflow negative pressure is generated in the transmission pipe 202, and then the gas is introduced through the air intake structure 4.
