Distribution switch control cabinets are widely used in various occasions, such as power plants, substations, industrial and mining enterprises, building hotels, and municipal construction, etc. According to different application scenarios and requirements, distribution cabinets can be divided into various types, such as low-voltage distribution cabinets, high-voltage distribution cabinets, fixed distribution cabinets, and draw-out distribution cabinets, etc. Each type of distribution cabinet has its specific application scenario and advantages.

[0003] Chinese Patent with the authorization announcement number CN114336323B discloses a dust-proof distribution cabinet, which includes a cabinet body and a cabinet door hinged to the cabinet body. A connection box is arranged on the outer side wall of the cabinet body, a connection port communicating with the connection box is opened on the inner side wall of the cabinet body, a blower for blowing air into the connection box is arranged on the outer side wall of the connection box adjacent to the cabinet body, a connecting rod is arranged on the inner side wall of the cabinet body on the same side as the connection port, and a control button for controlling the on-off of the blower is arranged on the connecting rod.

[0004] After opening the cabinet door in the above patent, the blower is started through the control button. The blower blows air into the cabinet body through the connection port, and the air flow flows from inside the cabinet body towards the outside, thereby reducing the entry of external dust into the cabinet body and ensuring the normal operation of the electrical components inside the cabinet body.

[0005] However, under harsh conditions, a large amount of dust will also adhere to the body of the staff member who opens the cabinet door. The above patent cannot handle the dust adhering to the staff member's body, and when the staff member repairs the distribution cabinet, the dust on their body is likely to fall into the distribution cabinet. Summary of the Invention

[0006] The present invention provides a housing structure of a distribution switch control cabinet and a distribution switch control cabinet, aiming to solve the problem that the dust adhering to the body of the staff member is likely to fall into the distribution cabinet when repairing the distribution cabinet in the related art.

Since the ventilation slots are distributed on both sides of the door frame, the air flow discharged from the ventilation slots will form a wind wall. When the staff passes through the wind wall, the dust attached to their bodies can be removed under the action of the air flow, thereby preventing the staff from bringing dust into the housing.

[0012] Preferably, the driving mechanism includes a connecting rod, a first pulling rope, a first pulley, a second pulley and a second pulling rope.

A limiting groove is provided on the rotating sleeve, and the limiting blocks can extend into the limiting groove to limit the rotation of the rotating sleeve unidirectionally.

[0019] The effect is that the limiting ring limits the rotation of the rotating sleeve unidirectionally, preventing the scraper from rotating during the air extraction process, thus affecting the air extraction of the fan into the cabinet body.

[0020] Preferably, a knocking rod is also rotatably fitted on the rotating sleeve. The knocking rod is slidably fitted with the mounting seat. A driving unit is provided in the rotating sleeve. The driving unit is used to drive the knocking rod to move reciprocally. The knocking rod passes through the filter plate and extends inward. First hammers and second hammers are spaced apart on the knocking rod. The first hammers and the second hammers are located on both sides of the filter plate and both can abut against the filter plate.

[0021] The effect is that the driving unit drives the knocking rod to move reciprocally, and then drives the first hammers and the second hammers to knock the filter plate, further improving the cleaning effect of the filter plate.

[0022] Preferably, the driving unit includes a slider, a first elastic member and a second elastic member. The slider is provided on the knocking rod. A first spiral groove and a second spiral groove are provided in the rotating sleeve. The two ends of the first spiral groove and the second spiral groove are respectively communicated through a first straight groove and a second straight groove. The slider can slide in the first spiral groove or the second spiral groove.

[0024] A distribution switch control cabinet includes a housing and internal components. The housing is the housing structure of the distribution switch control cabinet described in any one of the above, and the internal components are arranged inside the housing.

[0025] Advantageous effects: By adopting the housing structure of the distribution switch control cabinet of the present invention, it can effectively prevent dust from entering the housing, and thus can improve the service life of the internal components.

[0026] By adopting the above technical solution, the advantageous effects of the present invention are as follows:

Detailed implementation manners

[0042] The embodiments of the present invention will be described in detail below. The examples of the embodiments are shown in the drawings. The embodiments described below with reference to the drawings are exemplary and are intended to explain the present invention and should not be construed as a limitation to the present invention.

[0043] As Figures 1 to 10 shown, the housing structure of the distribution switch control cabinet of the present invention includes: a cabinet body 1, a fan 3, and a diversion assembly.

[0044] Specifically, as Figure 1 shown, a door frame is provided on the front side of the cabinet body 1, a cabinet door 2 is rotatably fitted at the door frame, an air inlet is provided on the right side of the cabinet body 1, an air outlet is provided on the left side of the cabinet body 1, and the fan 3 is fixedly connected to the inside of the air inlet.

[0045] As Figures 1 to 4As shown, the drainage component includes a diversion member 41 and a ventilation pipe 42. The diversion member 41 is slidably fitted on the inner wall of the cabinet body 1. The diversion member 41 is a frame structure. A ventilation opening 411 is provided in the lower region of the diversion member 41, and a wind baffle 412 is provided in its upper region. A partition plate 413 is provided between the wind baffle 412 and the ventilation opening 411. An opening is provided on the side wall of the diversion member 41. A drainage channel is formed between the diversion member 41, the wind baffle 412, the partition plate 413 and the opening. The ventilation pipe 42 is fixedly connected to the door frame of the cabinet body 1. A communication port 421 is provided on the ventilation pipe 42. A plurality of ventilation slots 422 are also provided on the ventilation pipe 42, and the ventilation slots 422 are located on both sides of the door frame of the cabinet body 1. A driving mechanism 5 is further provided in the cabinet body 1. The driving mechanism 5 includes a connecting rod 51, a first pulling rope 52, a first pulley 53, a second pulley 55 and a second pulling rope 57. The connecting rod 51 is provided at the top of the door frame of the cabinet body 1. The connecting rod 51 is rotationally fitted with the cabinet body 1 through a torsion spring. A roller is rotationally fitted at one end of the connecting rod 51, and the roller can abut against the cabinet door 2. The other end of it is fixedly connected to the first pulling rope 52. The first pulley 53 and the second pulley 55 are arranged in parallel at intervals on the inner wall of the cabinet body 1. Both the first pulley 53 and the second pulley 55 are located above the diversion member 41. The first pulley 53 is slidably fitted with the cabinet body 1 through a first rotating seat 54, and the first rotating seat 54 can move back and forth. The first pulley 53 is rotationally fitted with the first rotating seat 54. The other end of the second pulling rope 57 is fixedly connected to the first rotating seat 54. The second pulley 55 is fixedly connected to the cabinet body 1 through a second rotating seat 56, and the second pulley 55 is rotationally fitted with the second rotating seat 56. One end of the second pulling rope 57 is wound around the first rotating seat 54. After the second pulling rope 57 bypasses the first pulley 53 and the second pulley 55, it is fixedly connected to the diversion 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. The connecting rod 51 pulls the first rotating seat 54 to move forward through the first pulling rope 52. The first rotating seat 54 pulls the second pulling rope 57, so that the diversion member 41 moves upward. The diversion member 41 can cover the blower 3. The opening is aligned with the communication port 421, and the drainage channel is communicated with the communication port 421. The wind blown out by the blower 3 can enter the ventilation pipe 42 through the drainage channel and be discharged from the ventilation slots 422.

[0046] As 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 body 1. The filter plate 6 is located outside the fan 3. A cleaning mechanism is further provided outside 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 body 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 circumferential direction of the rotating sleeve 72. The scrapers 73 are inclined. A cleaning pad 8 is provided on the inner wall of the scraper 73. The cleaning pad 8 is a rubber pad. The cleaning pad 8 abuts against the outer wall of the filter plate 6. A limiting ring 9 is rotatably fitted on the rotating sleeve 72. The limiting ring 9 is fixedly connected to the mounting seat 71. A plurality of limiting blocks 91 are provided on the limiting ring 9. The limiting blocks 91 are evenly spaced along the circumferential direction of the limiting ring 9. Each limiting block 91 is elastically connected to the limiting ring 9 through a spring. The limiting block 91 can be retracted into the limiting ring 9. The limiting block 91 is an inclined plane block. A limiting groove 721 is provided on the rotating sleeve 72. The limiting groove 721 is an inclined plane groove. The limiting block 91 can extend into the limiting groove 721, so as to realize the one-way limit of the rotating sleeve 72. When the fan 3 blows air outwards, the wind force can push the scraper 73 to rotate clockwise. The scraper 73 can drive the rotating sleeve 72 to rotate. At this time, the rotating sleeve 72 can move from the bottom end of the inclined plane of the limiting block 91 to the top end of its inclined plane along the inclined plane of the limiting block 91. The rotating sleeve 72 can press the limiting block 91 into the limiting ring 9 during the rotation process, so as to prevent the limiting block 91 from hindering the rotation of the rotating sleeve 72. When the fan 3 sucks air inwards, the limiting block 91 extends into the limiting groove 721, so as to limit the counterclockwise rotation of the rotating sleeve 72, and further limit the rotation of the scraper 73, preventing the scraper 73 from hindering the air suction of the fan 3.

[0047] As Figure 5 、 Figures 8 to 10As shown, a knocking rod 10 is also rotatably fitted inside the rotating sleeve 72. One end of the knocking rod 10 passes through the filter plate 6 and extends inward. The knocking rod 10 is provided with a first knocking hammer 11 and a second knocking hammer 12. The first knocking hammer 11 and the second knocking hammer 12 are distributed at intervals and are located on both sides of the filter plate 6. The other end of the knocking rod 10 is slidably fitted with the mounting seat 71. A driving unit is provided on the knocking rod 10. The driving unit includes a slider 131, a first elastic member 132 and a second elastic member 133. The slider 131 is located inside the rotating sleeve 72 and is fixedly connected to the knocking rod 10. Both the first elastic member 132 and the second elastic member 133 are springs. The first elastic member 132 and the second elastic member 133 are respectively fixedly connected to both sides of the slider 131. The first elastic member 132 and the second elastic member 133 respectively abut against both ends of the rotating sleeve 72. First spiral grooves 722, second spiral grooves 723, first straight grooves 724 and second straight grooves 725 are provided on the inner wall of the rotating sleeve 72. The first spiral grooves 722 and the second spiral grooves 723 are respectively provided on both sides of the rotating sleeve 72. The head end of the first spiral groove 722 is communicated with the tail end of the second spiral groove 723 through the first straight groove 724. The head end of the second spiral groove 723 is communicated with the tail end of the first spiral groove 722 through the second straight groove 725. The slider 131 is slidably fitted in the first spiral groove 722 or the second spiral groove 723.

[0048] When the rotating sleeve 72 rotates clockwise, the slider 131 slides along the first spiral groove 722, moving 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 knocking hammer 11 abuts against 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 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 knocking hammer 12 abuts against 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 its 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. Repeating the above process multiple times enables the knocking rod 10 to move reciprocally along its axis, thereby driving the first knocking hammer 11 and the second knocking hammer 12 to alternately knock the filter plate 6, and vibrating the dust attached to the filter plate 6 to fall off.

[0049] As Figure 1 and Figure 5As shown in the figure, a first sensor 14 and a second sensor 15 are also provided inside the cabinet body 1. The first sensor 14 is provided at the top of the door frame of the cabinet body 1. The first sensor 14 is a contact sensor and can abut 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 inside the cabinet body 1. The first sensor 14 is electrically connected to the control board through an electric wire. The second sensor 15 is fixedly connected to the mounting seat 71. The second sensor 15 is an air velocity sensor and is used to detect the wind force at the air inlet. The second sensor 15 is electrically connected to the control board through an electric wire. The control board is electrically connected to the fan 3, and the control board can control the fan 3.

[0050] As Figure 11 As shown in the figure, the 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 distribution switch control cabinet in the embodiment of the present invention, and the internal components 2000 are provided inside the housing 1000. Through continuous air extraction by the fan 3, the cold air from the outside is drawn into the housing 1000. When the outside cold air passes through the filter plate 6, the filter plate 6 can filter out the dust and impurities mixed in the air from the air. The filtered air enters the housing 1000 and absorbs the heat dissipated by the internal components 2000 to form hot air, and the hot air is discharged from the air outlet of the housing 1000. When too much dust adheres to the filter plate 6 and causes the filter plate 6 to be blocked, the wind force at the air inlet decreases. The second sensor 15 transmits the wind force change data to the control board, and the control board controls the fan 3 to rotate in the reverse direction, so as to blow air outwards. During the blowing process, the fan 3 drives the scraping plate 73 to rotate. The scraping plate 73 scrapes the dust adhering to the filter plate 6 through the cleaning pad 8. The rotating sleeve 72 rotates synchronously with the scraping plate 73, thereby driving the knocking rod 10 to reciprocate axially, so that the first hammer 11 and the second hammer 12 alternately knock the filter plate 6, and the dust adhering to the filter plate 6 is shaken off through vibration to keep the filter plate 6 unobstructed.

[0051] When performing maintenance on the cabinet door 2, after the cabinet door 2 is opened, the first sensor 14 is separated from the cabinet door 2. The first sensor 14 sends an electrical signal to the control board to force the fan 3 to maintain the air extraction mode. The cabinet door 2 is opened and gradually moves away from the connecting rod 51. Under the action of the torsion spring, the connecting rod 51 rotates. The connecting rod 51 pulls the first rotating seat 54 forward through the first pulling rope 52. The first rotating seat 54 pulls the second pulling rope 57, thereby pulling the guiding member 41 upward, so that the wind baffle 412 covers the fan 3, the opening is aligned with the communication port 421, and the drainage channel is communicated with the communication port 421. The air 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 air flow discharged from the ventilation slots 422 will form an air wall at the door frame of the cabinet body 1. When the staff passes through the air wall, the dust attached to their bodies can be removed under the action of the air flow, thereby preventing the staff from bringing dust into the housing 1000.
