A connecting port 421 is provided on the ventilation pipe 42. A plurality of ventilation grooves 422 are also provided on the ventilation pipe 42. The ventilation grooves 422 are located on both sides of the door frame of the cabinet 1. A driving mechanism 5 is also provided in the cabinet 1, and the driving mechanism 5 includes a connecting rod 51, a first pull rope 52, a first pulley 53, a second pulley 55 and a second pull rope 57. The connecting rod 51 is provided at the top of the door frame of the cabinet 1, and the connecting rod 51 is rotatably matched with the cabinet 1 through a torsion spring. One end of the connecting rod 51 is rotatably matched with a roller, and the roller can stop against the cabinet door 2, and the other end thereof is fixedly connected to the first pull rope 52. The first pulley 53 and the second pulley 55 are distributed on the inner wall of the cabinet 1 in parallel and at intervals. The first pulley 53 and the second pulley 55 are both located above the guide member 41. The first pulley 53 is slidably matched with the cabinet 1 through a first rotating seat 54, and the first rotating seat 54 can move back and forth. The first pulley 53 and the first rotating seat 54 are rotatably matched, and the other end of the second pull rope 57 is fixedly connected to the first rotating seat 54. The second pulley 55 is The seat 56 is fixedly connected to the cabinet body 1, and the second pulley 55 and the second rotating seat 56 are rotatably matched. One end of the second pull rope 57 is wrapped around the first rotating seat 54. The second pull rope 57 passes around the first pulley 53 and the second pulley 55 and is fixedly connected to the guide member 41, so that the first pulley 53 becomes a movable pulley and the second pulley 55 becomes a fixed pulley. When the cabinet door 2 is opened, the cabinet door 2 gradually moves away from the connecting rod 51. Under the action of the torsion spring, the connecting rod 51 rotates, and the connecting rod 51 pulls the first rotating seat 54 forward through the first pull rope 52. The first rotating seat 54 pulls the second pull rope 57, so that the guide member 41 moves upward, and the guide member 41 can cover the fan 3. The opening is aligned with the connecting port 421, and the drainage channel is connected with the connecting port 421. The wind blown out by the fan 3 can enter the ventilation pipe 42 through the drainage channel and be discharged from the ventilation groove 422.

[0040] like Figures 5 to 7As shown, a filter plate 6 is also provided at the air inlet, the filter plate 6 is fixedly connected to the cabinet 1, the filter plate 6 is located on the outside of the fan 3, and a cleaning mechanism is also provided on the outside of the filter plate 6, the cleaning mechanism includes a mounting seat 71, a rotating sleeve 72 and a scraper 73, the mounting seat 71 is fixedly connected to the cabinet 1, the rotating sleeve 72 is rotatably fitted on the mounting seat 71, the scraper 73 is fixedly connected to one end of the rotating sleeve 72 close to the filter plate 6, a plurality of scrapers 73 are evenly spaced along the circumference of the rotating sleeve 72, the scrapers 73 are obliquely distributed, and a cleaning pad 8 is provided on the inner wall of the scraper 73, the cleaning pad 8 is a rubber pad, and the cleaning pad 8 is stopped against the outer wall of the filter plate 6. The rotating sleeve 72 is rotatably matched with the limiting ring 9, which is fixedly connected to the mounting seat 71. The limiting ring 9 is provided with a plurality of limiting blocks 91, which are evenly spaced along the circumference of the limiting ring 9. Each limiting block 91 is elastically connected to the limiting ring 9 through a spring, and the limiting block 91 can be received in the limiting ring 9. The limiting block 91 is an inclined block. The rotating sleeve 72 is provided with a limiting groove 721. The limiting groove 721 is an inclined groove, and the limiting block 91 can extend into the limiting groove 721, thereby realizing the unidirectional limiting of the rotating sleeve 72. When the fan 3 blows air outwards, the wind force can push the scraper 73 to rotate clockwise, and the scraper 73 can drive the rotating sleeve 72 to rotate. At this time, the rotating sleeve 72 can move along the inclined surface of the limit block 91 from the bottom end of the inclined surface of the limit block 91 to the top end of the inclined surface. During the rotation process, the rotating sleeve 72 can press the limit block 91 into the limit ring 9, thereby preventing the limit block 91 from hindering the rotation of the rotating sleeve 72. When the fan 3 draws air inwards, the limit block 91 extends into the limit groove 721, thereby limiting the counterclockwise rotation of the rotating sleeve 72, and then limiting the rotation of the scraper 73, preventing the scraper 73 from hindering the fan 3 from drawing air.

[0041] like Figure 5 , Figures 8 to 10As shown, a knocking rod 10 is also rotatably matched in the rotating sleeve 72, one end of the knocking rod 10 passes through the filter plate 6 and extends inward, a first hammer 11 and a second hammer 12 are provided on the knocking rod 10, the first hammer 11 and the second hammer 12 are spaced apart and located on both sides of the filter plate 6, and the other end of the knocking rod 10 is slidably matched with the mounting seat 71. A driving unit is provided on the knocking rod 10, and the driving unit includes a slider 131, a first elastic member 132 and a second elastic member 133, the slider 131 is located in the rotating sleeve 72 and is fixedly connected to the knocking rod 10, the first elastic member 132 and the second elastic member 133 are both springs, the first elastic member 132 and the second elastic member 133 are respectively fixedly connected to both sides of the slider 131, and the first elastic member 132 and the second elastic member 133 are respectively abutted against both ends of the rotating sleeve 72. A first spiral groove 722, a second spiral groove 723, a first straight groove 724 and a second straight groove 725 are provided on the inner wall of the rotating sleeve 72. The first spiral groove 722 and the second spiral groove 723 are respectively provided on both sides of the rotating sleeve 72. The head end of the first spiral groove 722 and the tail end of the second spiral groove 723 are connected through the first straight groove 724, and the head end of the second spiral groove 723 and the tail end of the first spiral groove 722 are connected through the second straight groove 725. The slider 131 is slidably fitted in the first spiral groove 722 or the second spiral groove 723.

[0042] When the rotating sleeve 72 rotates clockwise, the slider 131 slides along the first spiral groove 722 and moves from the head end of the first spiral groove 722 to its tail end. During this process, the slider 131 pushes the knocking rod 10 to move inward along the axial direction of the knocking rod 10 until the first hammer 11 stops with the filter plate 6. During this process, the first elastic member 132 contracts. When the slider 131 moves to the tail end of the first spiral groove 722, the first elastic member 132 releases its elastic force, thereby pushing the slider 131 to move in the second straight groove 725. The slider 131 moves from the tail end of the first spiral groove 722 to the head end of the second spiral groove 723. The rotation of the rotating sleeve 72 causes the slider 131 to slide along the second spiral groove 723. The slider 131 moves from the second spiral groove 72 3 moves from the head end of the second spiral groove 723 to the tail end of the second spiral groove 723. During this process, the slider 131 pushes the knocking rod 10 to move outward along the axial direction of the knocking rod 10 until the second hammer 12 stops with the filter plate 6. During this process, the second elastic member 133 contracts. When the slider 131 moves to the tail end of the second spiral groove 723, the second elastic member 133 releases the elastic force, thereby pushing the slider 131 to move in the first straight groove 724. The slider 131 moves from the tail end of the second spiral groove 723 to the head end of the first spiral groove 722. The above process is repeated many times, so that the knocking rod 10 can move back and forth along its axial direction, thereby driving the first hammer 11 and the second hammer 12 to alternately knock on the filter plate 6, and the dust attached to the filter plate 6 is shaken off by vibration.

[0043] like Figure 1 and Figure 5As shown, the cabinet 1 is further provided with a first sensor 14 and a second sensor 15. The first sensor 14 is provided at the top of the door frame of the cabinet 1. The first sensor 14 is a contact sensor. The first sensor 14 can stop against the cabinet door 2. The first sensor 14 is used to detect whether the cabinet door 2 is opened. A control board is provided in the cabinet 1. The first sensor 14 is electrically connected to the control board through wires. The second sensor 15 is fixedly connected to the mounting seat 71. The second sensor 15 is a wind speed sensor. The second sensor 15 is used to detect the wind force at the air inlet. The second sensor 15 is electrically connected to the control board through wires. The control board is electrically connected to the fan 3. The control board can control the fan 3.

[0044] like Fig.11 As shown, the power distribution switch control cabinet of the embodiment of the present invention includes a housing 1000 and internal components 2000. The housing 1000 is the housing structure of the power distribution switch control cabinet in the embodiment of the present invention, and the internal components 2000 are arranged in the housing 1000. The fan 3 continuously draws air to draw cold air from the outside into the housing 1000. When the cold air from the outside passes through the filter plate 6, the filter plate 6 can filter out impurities such as dust mixed in the air from the air. The filtered air enters the housing 1000 and absorbs the heat emitted by the internal components 2000 to form hot air. The hot air is discharged from the housing 1000 from the air outlet. When there is too much dust attached to the filter plate 6, causing the filter plate 6 to be blocked, the wind force at the air inlet is reduced, and the second sensor 15 transmits the wind force change data to the control board. The control board controls the fan 3 to rotate in the opposite direction, thereby blowing air outward. The fan 3 drives the scraper 73 to rotate during the blowing process. The scraper 73 scrapes off the dust attached to the filter plate 6 through the cleaning pad 8. The rotating sleeve 72 rotates synchronously with the scraper 73, thereby driving the knocking rod 10 to move back and forth along its axial direction, so that the first hammer 11 and the second hammer 12 alternately knock on the filter plate 6, and the dust attached to the filter plate 6 is shaken off by vibration, thereby keeping the filter plate 6 unobstructed.

[0045] When inspecting the cabinet door 2, after opening the cabinet door 2, the first sensor 14 is out of contact with the cabinet door 2, and the first sensor 14 sends an electrical signal to the control board, forcing the fan 3 to maintain the exhaust mode. The cabinet door 2 opens and gradually moves away from the connecting rod 51. Under the action of the torsion spring, the connecting rod 51 rotates, and the connecting rod 51 pulls the first rotating seat 54 forward through the first pull rope 52. The first rotating seat 54 pulls the second pull rope 57, thereby pulling the guide member 41 to move upward, so that the wind shield 412 covers the fan 3, the opening is aligned with the connecting port 421, and the drainage channel is connected to the connecting port 421. The wind blown out by the fan 3 can enter the ventilation pipe 42 through the drainage channel and be discharged from the ventilation slot 422. Since the ventilation slots 422 are distributed on both sides of the door frame, the airflow discharged from the ventilation slots 422 will form a wind wall at the door frame of the cabinet 1. When the staff passes through the wind wall, the dust attached to their bodies can be removed under the action of the airflow, thereby preventing the staff from bringing dust into the outer casing 1000.
