[0030] Embodiments of the present disclosure are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present disclosure, and are not to be construed as limitations of the present disclosure. On the contrary, the embodiments of the present disclosure include all changes, modifications, and equivalents that fall within the spirit and connotation of the appended claims.

[0031] like Figure 3 and Figure 4 As shown, the embodiment of the present disclosure proposes a drawer-type low-voltage power distribution cabinet, including a cabinet body 1, a drawer 3 and an electric mechanism. The cabinet body 1 is provided with a drawer groove 2, and the groove of the drawer groove 2 extends to the outer surface of the cabinet body 1. The drawer 3 is slidably arranged in the drawer groove 2 along the depth direction of the drawer groove 2. The electric mechanism is arranged in the drawer groove 2, and the electric mechanism is transmission-connected to the drawer 3. The electric mechanism is used to drive the drawer 3 to move in the drawer groove 2 along the depth direction of the drawer groove 2.

[0032] It can be understood that the electric mechanism drives the drawer 3 to move along the depth direction of the drawer slot 2, thereby realizing the electric pulling and pulling of the drawer 3 on the cabinet body 1, which is not only more convenient to operate, but also has a high degree of automation and utilizes the intelligent monitoring of the low-voltage distribution cabinet.

[0033] It should be noted that the specific type of the cabinet 1 can be set according to actual needs and is not limited to this. For example, the cabinet 1 is a closed shell made of steel plate, the slot of the drawer 2 extends to the front end of the cabinet 1, the depth direction of the drawer 2 is parallel to the front and rear direction of the cabinet 1, a busbar chamber is provided at the top of the cabinet 1, and a cable chamber is provided at the rear end of the cabinet 1.

[0034] When dust accumulates or parts fall in the low-voltage distribution cabinet, it is easy to cause the drawer 3 to have excessive resistance to movement or get stuck, causing the electric mechanism of the drawer 3 to be damaged due to excessive load, or even cause safety accidents such as fire.

[0035] like Figure 3 and Figure 4 As shown, in some embodiments, the electric mechanism includes a drive motor 7 and a control component 4, the drive motor 7 is arranged in the drawer slot 2, the drive motor 7 is transmission-connected to the drawer 3, the power output end of the control component 4 is connected to the power input end of the drive motor 7, and the current detection end of the control component 4 is connected to the power input end of the drive motor 7, and the control component 4 is used to control the drive motor 7 to operate or issue an alarm message according to the working current of the drive motor 7.

[0036] It can be understood that the control component 4 controls the action of the drive motor 7 to drive the drawer 3 to slide along the depth direction of the drawer slot 2, thereby realizing the electric pulling of the drawer 3 on the cabinet body 1, and the control component 4 determines the resistance of the drawer 3 when pulling by detecting the working current of the drive motor 7, so as to timely control the stop action of the drive motor 7 when the drawer 3 has too much resistance or is stuck, thereby avoiding the damage and fire of the drive motor 7 due to excessive load, which not only reduces the use cost of the low-voltage distribution cabinet, but also effectively improves the safety factor of the low-voltage distribution cabinet.

[0037] The control component 4 sends out an alarm message when the drawer 3 has too much resistance or is stuck, so that the operator can quickly identify the fault problem and carry out timely inspection and maintenance, ensuring that the low-voltage distribution cabinet maintains a high working efficiency.

[0038] It should be noted that when the drawer 3 encounters too much resistance or is stuck, the load of the drive motor 7 increases, and the operating current of the drive motor 7 also increases accordingly. Excessive operating current may cause damage to the drive motor 7 or even heat and fire. Therefore, the automatic control of the control component 4 can ensure the safe pulling and drawing of the drawer 3.

[0039] A current threshold should be set in the control component 4. When the working current of the drive motor 7 exceeds the current threshold, the control component 4 controls the drive motor 7 to stop and issues an alarm message. When the working current of the drive motor 7 is not greater than the current threshold, the control component 4 controls the drive motor 7 to operate to realize the pulling and pulling of the drawer 3.

[0040] The current threshold value may be set according to actual needs and is not limited thereto.

[0041] There are many reasons that lead to excessive resistance or jamming of the drawer 3 , for example, a lot of dust is accumulated on the moving path of the drawer 3 , and there are fallen screws, gaskets and other parts on the moving path of the drawer 3 .

[0042] The specific type of alarm information can be set according to actual needs, and there is no limitation on this. For example, the alarm information can be sound information; the alarm information can be light information; the alarm information can be sound and light information.

[0043] An evaluation model can be established based on the mapping relationship between the working current of the drive motor 7 and the resistance of the drawer 3, and alarm information of different intensities can be issued according to different resistances of the drawer 3, so that operators can quickly determine the cause of the failure of the drawer 3 and improve maintenance efficiency.

[0044] The specific type of the driving motor 7 can be set according to actual needs and is not limited thereto.

[0045] The specific number of drawers 3 can be set according to actual needs and is not limited thereto. Each drawer 3 is equipped with a drive motor 7 , and each drive motor 7 is equipped with a current detection terminal of a control component 4 .

[0046] The position of the drawer 3 in the drawer slot 2 can be determined by the control component 4. For example, the control component 4 includes a positioning pin and a plurality of photoelectric switches. The plurality of photoelectric switches are sequentially arranged in the drawer slot 2 along the depth direction of the drawer slot 2. The signal output end of the photoelectric switch is connected to the signal input end of the control component 4. The positioning pin is arranged on the drawer 3. Therefore, when the positioning pin passes through the photoelectric switch, the photoelectric switch sends an electrical signal to the control component 4. The control component 4 obtains the position of the drawer 3 in the drawer slot 2 according to the electrical signal, thereby further controlling the action of the drive motor 7 to make the drawer 3 reach the predetermined position.

[0047] The specific type and quantity of the photoelectric switches can be set according to actual needs and are not limited thereto.

[0048] like Figure 3As shown, in some embodiments, the electric mechanism also includes a screw rod 8, a first slider 9, a linkage plate 10 and a driving assembly 5. The screw rod 8 is rotatably arranged in the drawer groove 2, and the rotation center axis of the screw rod 8 is parallel to the depth direction of the drawer groove 2. The screw rod 8 is transmission-connected to the driving motor 7. The first slider 9 is slidingly arranged in the drawer groove 2 along the depth direction of the drawer groove 2. The first slider 9 is threadedly connected to the screw rod 8. A slot 11 is arranged at one end of the first slider 9 close to the drawer 3. The linkage plate 10 is rotatably arranged on the drawer 3, and the rotation center axis of the linkage plate 10 is parallel to the depth direction of the drawer groove 2. The driving assembly 5 is arranged on the drawer 3, and the driving assembly 5 is transmission-connected to the linkage plate 10. The driving assembly 5 is used to drive the linkage plate 10 to rotate so that the linkage plate 10 rotates into or out of the slot 11.

[0049] It can be understood that when the driving component 5 drives the interlocking plate 10 to rotate into the slot 11, the control component 4 controls the driving motor 7 to operate to drive the screw rod 8 to rotate. The rotation of the screw rod 8 drives the first sliding block 9 to slide along the depth direction of the drawer slot 2. The first sliding block 9 drives the drawer 3 to move along the depth direction of the drawer slot 2 through the interlocking plate 10, thereby realizing the pulling and pulling of the drawer 3; when the driving component 5 drives the interlocking plate 10 to rotate out of the slot 11, due to the separation between the interlocking plate 10 and the first sliding block 9, the drawer 3 can be pulled and pulled by manpower without being affected by components such as the screw rod 8 and the driving motor 7.

[0050] Therefore, through the transmission cooperation of the screw rod 8, the first slider 9 and the linkage plate 10, the drive motor 7 can stably drive the drawer 3, and the threaded transmission method between the screw rod 8 and the first slider 9 makes the movement accuracy of the drawer 3 higher, which is beneficial to the automatic operation of the low-voltage distribution cabinet.

[0051] At the same time, by rotating the linkage plate 10, the drawer 3 can be freely switched between manual pulling and electric pulling, which has higher flexibility and makes the use of the low-voltage distribution cabinet more convenient.

[0052] It should be noted that the arrangement of the screw rod 8 and the first sliding block 9 in the drawer groove 2 can be arranged according to actual needs and is not limited to this. For example, a first accommodating groove is arranged on the side wall of the drawer groove 2, and the groove opening of the first accommodating groove faces the drawer 3. The length direction of the first accommodating groove is parallel to the depth direction of the drawer groove 2. One end of the screw rod 8 is rotatably connected to the groove wall of the first accommodating groove near the groove opening of the drawer groove 2 through a bearing, and the other end of the screw rod 8 is connected to the output shaft of the driving motor 7 through a coupling, and the first sliding block 9 is slidably connected to the groove bottom of the first accommodating groove through a track.

[0053] The arrangement of the card slot 11 on the first slider 9 can be arranged according to actual needs and is not limited to this. For example, the notch of the card slot 11 faces the drawer 3, one side of the card slot 11 extends to the outer surface of the first slider 9, and the end of the linkage plate 10 away from the drawer 3 is rotated into or out of the card slot 11 from this side.

[0054] The control component 4 determines the resistance of the drawer 3 by detecting the working current of the drive motor 7. However, since the working current of the drive motor 7 is relatively large when it is started, the current threshold set in the control component 4 is also relatively large. Although the setting of the current threshold can avoid problems such as damage and fire of the drive motor 7, when the drawer 3 is pulled out of the drawer slot 2 and encounters an obstacle, due to the large current threshold, the drawer 3 is still moving toward the outside of the drawer slot 2 during the process of the working current reaching the current threshold, which can easily cause damage to the drawer 3 and the obstacle.

[0055] Therefore, if Figure 1 and Figure 4 As shown, in some embodiments, the drawer 3 includes a drawer box 301, an inner rod 302, an outer tube 303, an elastic member 304, a cover plate 305 and a distance sensor 306. The drawer box 301 is slidably arranged in the drawer groove 2 along the depth direction of the drawer groove 2, the linkage plate 10 is rotatably arranged at one end of the drawer box 301 close to the bottom of the drawer groove 2, the inner rod 302 is arranged at one end of the drawer box 301 close to the notch of the drawer groove 2, and the outer tube 303 is slidably sleeved on the end of the inner rod 302 away from the drawer box 301 along the depth direction of the drawer groove 2. The elastic member 304 is arranged in the outer tube 303, and the elastic member 304 abuts against one end of the inner rod 302 away from the drawer box 301. The cover plate 305 is arranged at one end of the outer tube 303 away from the inner rod 302, and the cover plate 305 abuts against the edge of the notch of the drawer groove 2. The distance sensor 306 is arranged between the drawer box 301 and the cover plate 305. The signal output end of the distance sensor 306 is connected to the signal input end of the control component 4. The distance sensor 306 is used to detect the distance between the drawer box 301 and the cover plate 305.

[0056] It can be understood that after the drawer box 301 is pulled back into the drawer groove 2, the cover plate 305 abuts against the edge of the notch of the drawer groove 2, thereby limiting the drawer box 301 and ensuring that the storage position of the drawer box 301 in the drawer groove 2 remains constant, while also ensuring the flatness of the surface of the cabinet body 1, which is beneficial to the automated operation of the low-voltage distribution cabinet.

[0057] The cover 305 is connected to the drawer 301 through the outer tube 303, the elastic member 304 and the inner tube, so that when the cover 305 hits an obstacle, there is a certain buffer space between the cover 305 and the drawer 301. At the same time, when the cover 305 hits an obstacle, the distance between the cover 305 and the drawer 301 also changes accordingly. Therefore, through the distance detection of the distance sensor 306, the control component 4 can control the drive motor 7 to stop the action according to the change of the distance between the cover 305 and the drawer 301, thereby avoiding damage to the drawer 3 and the obstacle due to the continued movement of the drawer 301, and effectively ensuring the safety of pulling out the drawer 3.

[0058] It should be noted that a distance threshold should be set in the control component 4. When the distance between the cover 305 and the drawer 301 is less than the distance threshold, the control component 4 controls the drive motor 7 to stop moving. When the distance between the cover 305 and the drawer 301 is greater than or equal to the distance threshold, the control component 4 controls the drive motor 7 to continue moving until the drawer 3 is pulled to a predetermined position.

[0059] The distance threshold can be set according to actual needs and is not limited thereto.

[0060] The arrangement of the distance sensor 306 between the drawer 301 and the cover 305 can be arranged according to actual needs, and there is no limitation on this. For example, the distance sensor 306 can be arranged at one end of the drawer 301 close to the cover 305, with its detection end facing the cover 305; the distance sensor 306 can be arranged on the side of the cover 305 close to the drawer 301, with its detection end facing the drawer 301. The specific type of the distance sensor 306 can be arranged according to actual needs, and there is no limitation on this.

[0061] The sliding structure of the outer cylinder 303 on the inner rod 302 can be set according to actual needs, and there is no limitation to this. For example, the outer cylinder 303 is a cylindrical structure, which has a hollow cavity running through both ends, and the central axis of the hollow cavity and the central axis of the inner rod 302 are both parallel to the depth direction of the drawer slot 2. The end of the inner rod 302 away from the drawer box 301 is slidably arranged in the hollow cavity, and at the same time, a first limiting plate is arranged at the end of the hollow cavity close to the drawer box 301, and a second limiting plate is arranged at the end of the inner rod 302 away from the drawer box 301, and the second limiting plate is located between the first limiting plate and the cover plate 305. Therefore, through the cooperation of the first limiting plate and the second limiting plate, the outer cylinder 303 and the inner rod 302 are limited to prevent the outer cylinder 303 from being separated from the inner rod 302. Among them, the elastic member 304 is arranged in the hollow cavity, and one end of the elastic member 304 is connected to the cover plate 305, and the other end of the elastic member 304 is connected to the second limiting plate.

[0062] The specific type of the elastic member 304 can be set according to actual needs, and there is no limitation on this. For example, the elastic member 304 can be a spring.

[0063] The inner rod 302 , the outer cylinder 303 and the elastic member 304 form a group of sliding components. The sliding components may be provided in only one group or in multiple groups. The multiple groups of sliding components are evenly distributed between the cover plate 305 and the drawer box 301 .

[0064] The specific type of the cover plate 305 can be set according to actual needs and is not limited to this. For example, a handle is provided on the side of the cover plate 305 away from the drawer box 301 to facilitate manual pulling of the drawer 3.

[0065] The arrangement of the linkage plate 10 on the drawer box 301 can be arranged according to actual needs and is not limited to this. For example, a second accommodating groove is arranged at one end of the drawer box 301 close to the bottom of the drawer groove 2, and the groove opening of the second accommodating groove is opposite to the groove opening of the first accommodating groove. After the linkage plate 10 is rotated out of the slot 11, it is stored in the second accommodating groove to avoid collision with other components in the drawer groove 2, thereby ensuring that the drawer box 301 remains smooth when pulled manually.

[0066] like Figure 1 As shown, in some embodiments, the driving assembly 5 includes a second slider 501, a first driving shaft 502, a hand wheel 503, a second driving shaft 504, a first gear 505 and a second gear 506. The second slider 501 is slidably arranged along the depth direction of the drawer groove 2 at one end of the drawer box 301 close to the notch of the drawer groove 2. The first driving shaft 502 is rotatably arranged on the second slider 501. The end of the first driving shaft 502 away from the second slider 501 penetrates the side of the cover plate 305 away from the drawer box 301. The rotation center axis of the first driving shaft 502 is parallel to the depth direction of the drawer groove 2. The hand wheel 503 is 3 is sleeved on one end of the first driving shaft 502 away from the second sliding block 501, and the hand wheel 503 is rotatably connected with the cover plate 305, the second driving shaft 504 is rotatably set on the drawer box 301, the rotation center axis of the second driving shaft 504 is parallel to the depth direction of the drawer groove 2, the linkage plate 10 is vertically set on the second driving shaft 504, the first gear 505 is sleeved on the first driving shaft 502, the second gear 506 is sleeved on the second driving shaft 504, the second gear 506 is meshed with the first gear 505, and the first gear 505 is slidably connected with the second gear 506 along the depth direction of the drawer groove 2.

[0067] It can be understood that the rotation of the handwheel 503 drives the first drive shaft 502 to rotate, the first drive shaft 502 drives the second drive shaft 504 to rotate through the engagement of the first gear 505 and the second gear 506, and the second drive shaft 504 drives the linkage plate 10 to rotate. Thus, the linkage plate 10 can be rotated in or out of the slot 11 by rotating the handwheel 503. The operation is simple and convenient, and the mechanical transmission control method has higher stability.

[0068] Among them, by setting the second slider 501 and slidingly connecting the first gear 505 and the second gear 506, while ensuring the stable rotation of the first drive shaft 502 and the stable transmission of the first gear 505 and the second gear 506, the relative movement between the cover plate 305 and the drawer box 301 is avoided.

[0069] It should be noted that the sliding setting method of the second slider 501 on the drawer 301 can be set according to actual needs and is not limited to this. For example, a slide groove is set at one end of the drawer 301 close to the cover 305, and the groove of the slide groove is opposite to the cover 305, and the slider is slidably set in the slide groove.

[0070] The arrangement of the second drive shaft 504 on the drawer 301 can be arranged according to actual needs and is not limited to this. For example, a third accommodating groove is arranged in the drawer 301, and the groove opening of the third accommodating groove extends to one end of the drawer 301 close to the cover 305, and the groove bottom of the third accommodating groove is connected to the second accommodating groove. The second drive shaft 504 is rotatably arranged in the third accommodating groove, and a second gear 506 is arranged after one end of the second drive shaft 504 extends out of the groove opening of the third accommodating groove, and a linkage plate 10 is arranged after the other end of the second drive shaft 504 extends into the second accommodating groove.

[0071] The arrangement of the handwheel 503 on the cover plate 305 can be arranged according to actual needs and is not limited to this. For example, a fourth accommodating groove is arranged on the side of the cover plate 305 away from the drawer box 301, and the handwheel 503 is rotatably arranged in the fourth accommodating groove. The bottom of the fourth accommodating groove extends to the side of the cover plate 305 close to the drawer box 301, and one end of the first driving shaft 502 away from the second slider 501 extends from the bottom of the fourth accommodating groove into the fourth accommodating groove and is connected to the handwheel 503.

[0072] The length of the first gear 505 can be set according to actual needs and is not limited thereto. However, when the cover plate 305 moves arbitrarily relative to the drawer box 301 , the length of the first gear 505 should be set to ensure that the first gear 505 can always mesh with the second gear 506 .

[0073] In order to reduce the interference of the external environment on the driving assembly 5, a protective structure can be set between the cover 305 and the drawer box 301. The specific type of the protective structure can be set according to actual needs and is not limited to this. For example, the protective structure can be a rubber bellows cover.

[0074] Since the cover 305 is connected to the drawer box 301 through the outer tube 303, the elastic member 304 and the inner tube, there is a certain buffer space between the cover 305 and the drawer box 301, so that when the drawer 3 is pulled out manually, the cover 305 can abut against the edge of the groove of the drawer groove 2, and the drawer box 301 cannot be reset to the initial position.

[0075] Therefore, if Figure 1As shown, in some embodiments, the driving assembly 5 also includes a third driving shaft 507, a third gear 508 and a baffle 509. The third driving shaft 507 is rotatably arranged at one end of the drawer box 301 close to the cover plate 305. The rotation center axis of the third driving shaft 507 is parallel to the depth direction of the drawer groove 2. The third gear 508 is sleeved on the third driving shaft 507. The third gear 508 is meshed with the first gear 505, and the first gear 505 is slidingly connected to the third gear 508 along the depth direction of the drawer groove 2. The baffle 509 is vertically arranged on the third driving shaft 507, wherein the end of the baffle 509 away from the third driving shaft 507 abuts against the end of the outer cylinder 303 away from the cover plate 305, and the end of the linkage plate 10 away from the second driving shaft 504 rotates out of the slot 11, or the end of the baffle 509 away from the third driving shaft 507 is away from the outer cylinder 303, and the end of the linkage plate 10 away from the second driving shaft 504 rotates into the slot 11.

[0076] It can be understood that the rotation of the handwheel 503 drives the first drive shaft 502 to rotate, the first drive shaft 502 drives the third drive shaft 507 to rotate through the engagement of the first gear 505 and the third gear 508, and the third drive shaft 507 drives the baffle 509 to rotate, thereby, the abutment or separation between the baffle 509 and the outer cylinder 303 is achieved by rotating the handwheel 503.

[0077] Among them, since the third driving shaft 507 and the baffle 509 are arranged on the drawer box 301, and the outer tube 303 is arranged on the cover plate 305, when the baffle 509 abuts against the outer tube 303, the cover plate 305 and the drawer box 301 cannot move relative to each other, so that when the drawer 3 is pulled out manually, the cover plate 305 can abut against the edge of the groove of the drawer groove 2, and at the same time the drawer box 301 is reset to the initial position, which is beneficial to the automatic operation of the low-voltage distribution cabinet.

[0078] The hand wheel 503 is used to simultaneously control the rotation of the linkage plate 10 and the baffle plate 509, which effectively simplifies the overall structure and operation, making the operation of the drawer 3 when pulled out manually simpler and more convenient to use.

[0079] It should be noted that when the drawer 3 is pulled out manually, the hand wheel 503 is turned so that the end of the baffle 509 away from the third drive shaft 507 abuts against the end of the outer cylinder 303 away from the cover plate 305, and the end of the linkage plate 10 away from the second drive shaft 504 rotates out of the slot 11. When the drawer 3 is pulled out electrically, the end of the baffle 509 away from the third drive shaft 507 moves away from the outer cylinder 303, and the end of the linkage plate 10 away from the second drive shaft 504 rotates into the slot 11.

[0080] The arrangement of the baffle 509 on the third drive shaft 507 can be arranged according to actual needs and is not limited to this. For example, an inclined rod is arranged between the baffle 509 and the third drive shaft 507 to strengthen the structural strength of the baffle 509 on the third drive shaft 507, thereby ensuring that the baffle 509 can stably support the outer cylinder 303.

[0081] like Figure 3 As shown, in some embodiments, the driving assembly 5 also includes a first magnetic component 510, a second magnetic component 511 and a third magnetic component 512, the first magnetic component 510 is arranged on the linkage plate 10, the second magnetic component 511 is arranged in the card slot 11, and the third magnetic component 512 is arranged on the drawer box 301, wherein the first magnetic component 510 and the second magnetic component 511 are magnetically attracted to each other, or the first magnetic component 510 and the third magnetic component 512 are magnetically attracted to each other.

[0082] It can be understood that when the drawer 3 is pulled out manually, the first magnetic member 510 and the third magnetic member 512 attract each other, so that the baffle 509 and the outer tube 303 can be stably abutted, and when the drawer 3 is pulled out electrically, the first magnetic member 510 and the second magnetic member 511 attract each other, so that the linkage plate 10 and the first slider 9 can be stably connected. Therefore, through the cooperation of the first magnetic member 510, the second magnetic member 511 and the third magnetic member 512, the pulling and pulling stability of the drawer 3 is higher and the use is more convenient.

[0083] It should be noted that the third magnetic member 512 can be arranged on the drawer box 301 according to actual needs and is not limited thereto. For example, the third magnetic member 512 is arranged in the second receiving groove.

[0084] The specific types of the first magnetic member 510, the second magnetic member 511 and the third magnetic member 512 can be set according to actual needs and are not limited thereto. For example, the first magnetic member 510 can be a magnet, and the second magnetic member 511 and the third magnetic member 512 can both be iron blocks.

[0085] like Figure 2 and Figure 3 As shown, in some embodiments, a guide rail 12 is provided in the drawer groove 2 along the depth direction of the drawer groove 2, a rail groove is provided on the drawer 3 along the depth direction of the drawer groove 2, the guide rail 12 is slidably connected to the rail groove, and the drawer-type low-voltage power distribution cabinet also includes a cleaning component 6, which is arranged at one end of the drawer 3 close to the bottom of the drawer groove 2, and the cleaning end of the cleaning component 6 is in contact with the guide rail 12.

[0086] It can be understood that, through the cooperation between the guide rail 12 and the rail groove, the drawer 3 can slide stably in the drawer groove 2, and through the setting of the cleaning component 6, the dust, parts, etc. on the guide rail 12 can be cleaned, thereby effectively reducing the shutdown frequency of the low-voltage distribution cabinet and improving the working efficiency of the low-voltage distribution cabinet.

[0087] It should be noted that the specific type of the cleaning component 6 can be set according to actual needs and is not limited to this. For example, the cleaning component 6 may include a cleaning brush, which is fixedly arranged at one end of the drawer box 301 away from the slot of the drawer groove 2, and the cleaning brush abuts against the guide rail 12. Thus, the guide rail 12 is cleaned by the following movement of the cleaning brush and the drawer 3.

[0088] In addition, if Figure 2 As shown, in some embodiments, the cleaning assembly 6 includes a rack 601, a fourth gear 602, a transmission shaft 603 and two cleaning rollers 604, the rack 601 is arranged in the drawer slot 2 along the depth direction of the drawer slot 2, the fourth gear 602 is rotatably arranged on the drawer 3, the rotation center axis of the fourth gear 602 is perpendicular to the depth direction of the drawer slot 2, the fourth gear 602 is meshed with the rack 601, the transmission shaft 603 is rotatably arranged in the drawer 3, the rotation center axis of the transmission shaft 603 is perpendicular to the depth direction of the drawer slot 2, the transmission shaft 603 and the fourth gear 60 2, a cleaning roller 604 is rotatably arranged at one end of the drawer 3 near the bottom of the drawer slot 2, a rotation center axis of the cleaning roller 604 is parallel to the depth direction of the drawer slot 2, two cleaning rollers 604 are symmetrically distributed on both sides of the guide rail 12, the cleaning roller 604 is connected to the transmission shaft 603 by bevel gear transmission, a plurality of brushes 605 are arranged on the outer circumferential surface of the cleaning roller 604, the brush 605 located below the cleaning roller 604 abuts against the guide rail 12, and the brush 605 located below the cleaning roller 604 rotates with the cleaning roller 604 in a direction away from the guide rail 12.

[0089] It can be understood that the fourth gear 602 moves synchronously with the drawer 3 in the drawer slot 2, and since the rack 601 is arranged in the drawer slot 2, the fourth gear 602 rotates relative to the rack 601, and the rotation of the fourth gear 602 drives the transmission shaft 603 to rotate, and the transmission shaft 603 drives the two cleaning rollers 604 to rotate synchronously. At the same time, since a plurality of brushes 605 are arranged on the cleaning roller 604, the cleaning roller 604 rotates while using the plurality of brushes 605 thereon to clean the guide rail 12, thereby effectively reducing dust, parts, etc. accumulated on the guide rail 12, thereby reducing the shutdown frequency of the low-voltage distribution cabinet and improving the working efficiency of the low-voltage distribution cabinet.

For example, the rack 601 is arranged in the first receiving slot, one end of the rack 601 is connected to the end of the first receiving slot close to the slot opening of the drawer slot 2, and the other end of the rack 601 is connected to the end of the first receiving slot close to the bottom of the drawer slot 2, and the teeth of the rack 601 face downward.

[0091] The transmission structure of the transmission shaft 603 and the fourth gear 602 can be set according to actual needs and is not limited to this. For example, a fifth accommodating groove is provided at one end of the drawer box 301 away from the groove of the drawer groove 2, and the transmission shaft 603 is rotatably set in the fifth accommodating groove. One end of the transmission shaft 603 extends out of the fifth accommodating groove and is sleeved with the fourth gear 602.

[0092] The transmission structure of the transmission shaft 603 and the two cleaning rollers 604 can be set according to actual needs, and there is no limitation to this. For example, the transmission shaft 603 is provided with a first bevel gear and a second bevel gear, and the rotating shaft of the cleaning roller 604 extends into the fifth accommodating groove, and the rotating shaft of the cleaning roller 604 is provided with a third bevel gear. The first bevel gear is meshed with the third bevel gear on one cleaning roller 604, and the second bevel gear is meshed with the third bevel gear on the other cleaning roller 604, and the first bevel gear and the second bevel gear are in opposite directions. Therefore, when the transmission shaft 603 rotates, the transmission shaft 603 drives the two cleaning rollers 604 to rotate synchronously through the cooperation of the first bevel gear, the second bevel gear and the third bevel gear.

[0093] The specific type of the cleaning roller 604 can be set according to actual needs and is not limited to this.
