DETAILED DESCRIPTION

[0028] Embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0029] like Figures 1 to 8 As shown, a cleaning device for a power distribution cabinet of the present invention comprises a frame 1, a cleaning mechanism and a liquid spraying mechanism.

[0030] In this embodiment, for ease of understanding, the length direction of the frame 1 is defined as the left-right direction, and the width direction of the frame 1 is defined as the front-back direction.

[0031] The frame 1 is provided with a handle 11 for pulling or pushing the frame 1 to move, and a roller is installed at the lower end of the frame 1. When in use, the frame 1 is moved to the side of the distribution cabinet 6, and then the cleaning liquid is sprayed onto the outer wall of the distribution cabinet 6 by the spray mechanism. At the same time, the outside of the distribution cabinet 6 is cleaned by the cleaning mechanism. In order to ensure the heat dissipation effect of the distribution cabinet 6, the distribution cabinet 6 is usually provided with heat dissipation holes, most of which are arranged in an array, and a protective member 61 is added on the outside. The protective member 61 is usually a C-shaped structure or an arc structure, which can hide the heat dissipation holes, isolate them from rain and dust from the outside, and reduce pollution and damage to internal electrical components.

[0032] The cleaning mechanism includes a flat brush assembly, an oblique brush assembly and a driving assembly 1. A moving block 2 is provided on the frame 1. The driving assembly 1 is used to drive the moving block 2 to move along the height or length direction of the frame 1. The flat brush assembly includes a cleaning brush 3. The cleaning brush 3 is rotatably arranged on the side of the moving block 2 facing the distribution cabinet 6. The cleaning brush 3 is made of a flexible material. The oblique brush assembly includes a brush 4 and a driving structure 1. The brush 4 is arranged on the lower side of the cleaning brush 3. The brush 4 is provided with a plurality of obliquely arranged bristles 41. The driving structure 1 is used to drive the bristles 41 to extend out of the moving block 2. outside or retracted into the moving block 2; the spray component includes a liquid storage box 5 and a driving component 2, and the moving block 2 is provided with a plurality of spray holes 51 communicated with the liquid storage box 5 on the side facing the cleaning brush 3, and the spray holes 51 are located on the upper side of the cleaning brush 3, and the driving component 2 is used for driving the spray holes 51 to open when the cleaning brush 3 cleans the outer wall of the distribution cabinet 6, spraying cleaning liquid to the outer wall of the distribution cabinet 6 to enhance the cleaning effect, and driving the spray holes 51 to close when the brush 4 cleans the heat dissipation holes provided on the distribution cabinet 6 to prevent the cleaning liquid from entering the interior of the cabinet.

[0033] Specifically, Figures 1 to 8 As shown, by moving the frame 1, the cleaning mechanism is moved to the side of the distribution cabinet 6, and the position of the frame 1 is adjusted so that the cleaning brush 3 gradually approaches the outer wall of the distribution cabinet 6. When the cleaning brush 3 contacts the outer wall of the distribution cabinet 6, the driving component 2 drives the spray hole 51 to open, spraying the cleaning liquid onto the outer wall of the distribution cabinet 6, and then the cleaning brush 3 starts to rotate, using the flexible material to effectively clean the outer wall of the distribution cabinet 6. At this time, the driving component 1 drives the moving block 2 to move along the length and height direction of the frame 1, and drives the cleaning brush 3 to move, so that the cleaning brush 3 gradually cleans the outer wall of the distribution cabinet 6; when the moving block 2 moves to When the heat dissipation hole is at the position, the driving component 2 controls the liquid spray hole 51 to close, stops spraying the cleaning liquid, and prevents the cleaning liquid from entering the cabinet. Then the driving structure 1 drives the bristles 41 to extend outward. At this time, the dust and dirt in the heat dissipation hole can be cleaned by the inclined bristles 41. At the same time, the cleaning brush 3 can clean the outer wall of the protective member 61. After the cleaning is completed, the driving structure 1 drives the bristles 41 to retract into the moving block 2, so that the bristles 41 withdraw from the heat dissipation hole, and the cleaning of the heat dissipation hole is completed; then, by moving the frame 1, multiple outer walls of the distribution cabinet 6 are cleaned in turn, and the above-mentioned cleaning process of the outer wall and the heat dissipation hole is repeated; Among them, in this embodiment, the cleaning brush 3 and the bristle brush 4 adopt a reciprocating and row-by-row cleaning method. Specifically, by moving the frame 1, the cleaning brush 3 is moved to the starting position of the outer wall of the distribution cabinet 6, usually one side of the top, and then the cleaning brush 3 starts to move horizontally to clean the outer wall part at this height. After the horizontal movement is completed, the cleaning brush 3 moves downward a certain distance, which can be the height of a cleaning brush 3, and then the cleaning brush 3 moves horizontally again to clean the new height area, and then repeat the above-mentioned horizontal movement and vertical movement steps to gradually cover the entire area of ​​the outer wall of the distribution cabinet 6 until the entire cleaning process is completed.

[0034] In some embodiments, a driving component 1 includes a screw 1 21 and a screw 22, and two screws 1 21 are provided. The two screws 21 are longitudinally rotated and arranged on the left and right sides of the frame 1 respectively, and a motor 1 is provided on the frame 1 for independently driving each screw 1 21 to rotate. Each screw 1 21 is provided with a slider 1 23 threadedly matched therewith, and the screw 2 22 is horizontally arranged, and the two ends of the screw 2 22 are respectively rotationally matched with the two sliders 1 23, and one of the sliders 1 23 is provided with a motor 2 for driving the screw 2 22 to rotate, and the moving block 2 is threadedly matched with the screw 2 22.

[0035] Specifically, Figures 1 to 3 As shown, the two screw rods 21 are driven to rotate by the corresponding motor 1, so that the two screw rods 21 rotate synchronously. Due to the threaded cooperation between the screw rod 21 and the slider 23, the slider 23 is driven to move along the axial direction of the screw rod 21. Since the two ends of the screw rod 22 are rotationally cooperated with the slider 23, the screw rod 22 moves synchronously with the slider 23, and drives the moving block 2 provided on the screw rod 22 to move, so that the cleaning brush 3 and the brush 4 move along the height direction of the distribution cabinet 6 to clean the distribution cabinet 6; the screw rod 22 is driven to rotate by the motor 2. Due to the threaded cooperation between the moving block 2 and the screw rod 22, when the screw rod 22 rotates, the moving block 2 moves along the axial direction of the screw rod 22, so that the cleaning brush 3 and the brush 4 move along the length or width direction of the distribution cabinet 6 to clean the distribution cabinet 6. Therefore, through the coordinated work of the screw rod 1 21 and the screw rod 22, the cleaning brush 3 and the brush 4 can gradually clean the outside of the distribution cabinet 6.

[0036] In some embodiments, a screw rod 3 24 is provided on the frame 1 for rotating along the left and right directions, and a motor 3 is provided on the frame 1 for driving the screw rod 3 24 to rotate, and threads with opposite rotation directions are provided at both ends of the screw rod 3 24, and sliders 25 are provided at the lower ends of the two screw rods 1 21 for rotating, and the two sliders 25 are respectively matched with the threads of the screw rod 3 24 through two sections of threads, and positioning pieces 26 are provided on the two sliders 25.

[0037] Specifically, Figures 1 to 3As shown, when the starting motor three drives the screw rod three 24 to rotate, it can drive the slider two 25 that cooperates with the thread therewith to move. Since the two sections of the thread rotate in opposite directions, the two sliders two 25 will move in opposite directions, so that the two sliders two 25 are closer to each other or farther away from each other. Therefore, by adjusting the distance between the two sliders two 25, the two positioning members 26 are respectively in contact with the two sides of the distribution cabinet 6, the distance between the two screw rods one 21 can be determined, and the horizontal movement range of the moving block 2 can be adjusted, so that the cleaning mechanism can adapt to distribution cabinets 6 of different widths, ensure the cleaning efficiency, and improve the applicability of the device.

[0038] In some embodiments, a driving structure 2 for driving the cleaning brush 3 to rotate is provided on the moving block 2, and the driving structure 2 includes a rack 1 31, a gear 1 32, a bevel gear 1 33 and a bevel gear 2 34. The rack 1 31 is arranged between the two sliders 1 23 and horizontally slides with the moving block 2. The gear 1 32 and the bevel gear 1 33 are coaxially rotated and arranged in the moving block 2, and the gear 1 32 and the rack 1 31 are meshed for transmission. The bevel gear 2 34 is fixedly connected to the cleaning brush 3, and the bevel gear 1 33 and the bevel gear 2 34 are meshed for transmission.

[0039] Specifically, Figures 2 to 6 As shown, when the screw rod 22 is driven to rotate by the motor 2, the moving block 2 will move along the axial direction of the screw rod 22, so that the moving block 2 moves relative to the rack 1 31. As the moving block 2 moves, the gear 1 32 arranged in the moving block 2 will be driven to move synchronously. At this time, through the meshing transmission between the rack 1 31 and the gear 1 32, the gear 1 32 will be driven to rotate, and the bevel gear 1 33 will be driven to rotate synchronously, and under the meshing transmission between the bevel gear 1 33 and the bevel gear 2 34, the bevel gear 2 34 will be driven to rotate, so that the cleaning brush 3 starts to rotate. The rotation of the cleaning brush 3 can quickly loosen and remove the dust, dirt and debris attached to the outer wall of the distribution cabinet 6, thereby improving the cleaning efficiency and cleaning effect.

[0040] In some embodiments, the driving structure 1 includes a sliding block 42 and a connecting rod 1 43. The sliding block 42 includes a sliding part 1 421 and a sliding part 2 422. The sliding part 1 421 is longitudinally slidably arranged between the cleaning brush 3 and the brush 4, and an elastic member 1 44 is provided between the sliding part 1 421 and the moving block 2 for driving the sliding part 1 421 to reset. The elastic member 1 44 can be a spring. The sliding part 2 422 is horizontally slidably arranged on the side of the sliding part 1 421 facing the cleaning brush 3, and an elastic member 2 is provided between the two. The elastic member 2 can be a spring. The brush 4 includes a mounting sleeve 45 and a mounting rod 46. The mounting sleeve 45 is rotationally matched with the moving block 2, and the mounting rod 46 is horizontally slidably matched with the mounting sleeve 45 along its axial direction. Multiple bristles 41 are all installed on one end of the mounting rod 46 facing the mounting sleeve 45, and are slidably matched with the mounting sleeve 45. The connecting rod 1 43 is arranged between the sliding block 42 and the mounting rod 46, and its two ends are respectively hinged to the sliding part 1 421 and the mounting rod 46.

[0041] Specifically, Figures 2 to 8 As shown, after the cleaning brush 3 completes the horizontal movement to a certain height, the screw 21 is rotated to drive the moving block 2 to move downward, and drive the cleaning brush 3, the brush 4 and the sliding block 42 to move downward synchronously. If there is a heat dissipation hole below the moving block 2 at this time, as the moving block 2 moves downward, the sliding portion 422 in the sliding block 42 will be blocked by the first row of protective members 61, so that the sliding block 42 stops moving downward, and the moving block 2 and the brush 4 will continue to move downward until the brush 4 moves between the first and second rows of protective members 61. In this process, the sliding block 4 The relative movement between the connecting rod 43 and the moving block 2 will compress the elastic member 44 to store force, and increase the distance between the sliding portion 421 and the mounting rod 46, so that the connecting rod 43 rotates around the hinge point between the connecting rod 43 and the sliding portion 421. As the connecting rod 43 rotates, the mounting rod 46 is pulled to move toward the mounting sleeve 45, and the bristles 41 are driven to extend outward relative to the mounting sleeve 45. At this time, the inclined bristles 41 extend into the heat dissipation holes below the protective member 61, and the heat dissipation holes in the first row are gradually cleaned through the horizontal movement of the moving block 2. After cleaning the heat dissipation holes in the first row, the moving block 2 is driven by the screw 21 to continue to move downward by a certain distance, and this distance can be the distance between the two adjacent rows of heat dissipation holes. In the process of the moving block 2 moving downward, the sliding part 422 will move in the direction close to the sliding part 421, and the elastic part 2 will be compressed to store force, so that the sliding block 42 can smoothly pass over the protective part 61 in the first row. In this process, the sliding part 422 moves out of position, which will make the sliding block 42 lose the obstruction of the protective part 61. At this time, the elastic part 44 will release the accumulated force to drive the sliding block 42 to reset. As the sliding block 42 is reset, the distance between the sliding part 421 and the mounting rod 46 will increase, and the connecting rod 43 will be squeezed to rotate in the opposite direction, while pushing the mounting rod 46 to move in the direction away from the mounting sleeve 45, so that the bristles 41 are retracted into the mounting sleeve 45, so as to avoid the collision between the bristles 41 and the protective part 61 and damage to the bristles 41 during the downward movement of the moving block 2. When the sliding block 42 passes over the protective member 61 of the first row, the elastic member 2 accumulates force and releases it, driving the sliding part 2 422 to extend outward, so that the sliding block 42 is located between the protective members 61 of the first row and the second row, and the brush 4 is located between the protective members 61 of the second row and the third row. At this time, as the moving block 2 continues to move downward, the sliding block 42 will be blocked by the protective member 61 of the second row, so that the sliding block 42 and the moving block 2 will move relative to each other again, and through the rotation of the connecting rod 1 43, the bristles 41 will extend again to clean the heat dissipation holes in the second row; then repeat the above steps until all the heat dissipation holes are cleaned.

[0042] In some embodiments, a driving structure three is provided on the moving block 2 for driving the mounting sleeve 45 to rotate. The driving structure three includes a rack 2 47 and a gear 2 48. The rack 2 47 is provided between the two sliders 23 and cooperates with the moving block 2 for horizontal sliding. The gear 2 48 is connected to the end of the mounting rod 46 away from the bristles 41, and the gear 2 48 can mesh with the rack 2 47 for transmission.

[0043] Specifically, Figures 4 to 8As shown, during the downward movement of the moving block 2, the blocking of the sliding block 42 by the protective member 61 causes the sliding block 42 to move relative to the moving block 2, and causes the connecting rod 1 43 to rotate, thereby pulling the mounting rod 46 to move in the direction close to the mounting sleeve 45, so that the bristles 41 extend out of the mounting sleeve 45 to clean the heat dissipation holes. In this process, as the mounting rod 46 moves, the gear 2 48 is driven to move, so that the gear 2 48 is meshed with the rack 2 47, so that when the moving block 2 moves horizontally, the meshing transmission between the gear 2 48 and the rack 2 47 can drive the gear 2 48 to rotate, so that the mounting rod 46 and the mounting sleeve 45 rotate, and the bristles 41 rotate around the axis of the mounting rod 46. The rotation of the bristles 41 can improve the cleaning efficiency and cleaning effect of the heat dissipation holes. After the sliding block 42 loses the obstruction of the protective member 61, it will move and reset under the action of the elastic member 44, and cause the connecting rod 43 to rotate in the opposite direction, so that the mounting rod 46 moves away from the mounting sleeve 45 for reset, and the bristles 41 are retracted into the mounting sleeve 45. In this process, as the mounting rod 46 is reset, the gear 2 48 and the rack 2 47 will be disengaged, so that the mounting sleeve 45 and the mounting rod 46 stop rotating, and the bristles 41 stop rotating.

[0044] In some embodiments, driving component 2 includes a block 52, an eccentric rod 53, a connecting rod 2 54 and a flexible connecting member 55. A liquid storage chamber 201 communicating with the liquid injection hole 51 is provided in the moving block 2, and a through hole 202 for connecting the liquid storage chamber 201 with the inside of the liquid storage box 5 is provided on the moving block 2. The block 52 is horizontally slidably arranged in the liquid storage chamber 201, and can close or open the through hole 202. The eccentric rod 53 is eccentrically arranged at the upper end of the gear 1 32. The connecting rod 2 54 is provided in two and is symmetrically arranged on the left and right sides of the gear 1 32. One end of each connecting rod 2 54 is hinged to the block 52 through a torsion spring, and the other end of each connecting rod 2 54 is connected to a rod 541. The flexible connecting member 55 is sleeved on the outside of the two rods 541. The eccentric rod 53 is located in the middle of the flexible connecting member 55. The sliding part 1 421 and the bevel gear 1 33 are fixedly connected by a connecting rod 49, so that the two can move up and down synchronously.

[0045] Specifically, Figures 4 to 8As shown, in the initial state, the gear 1 32 and the rack 1 31 are in meshing state, so that during the horizontal movement of the moving block 2, the gear 1 32 can be driven to rotate through the meshing transmission of the gear 1 32 and the rack 1 31. At this time, the eccentric rod 53 will rotate with the gear 1 32 to generate eccentric motion. During the movement of the eccentric rod 53, the connecting rod 2 54 will be pulled by the flexible connecting member 55 to rotate around the hinge point between it and the block 52, and the block 52 will be pulled to reciprocate. The reciprocating motion of the block 52 can make the through hole 202 open or close periodically, and the cleaning liquid enters the liquid storage chamber 201 through the through hole 202, and the reciprocating motion of the block 52 pushes the cleaning liquid to spray outward from the spray hole 51 to the outer wall of the distribution cabinet 6; When the moving block 2 moves downward, the blocking of the sliding block 42 by the protective piece 61 will cause relative movement between the sliding block 42 and the moving block 2. As the sliding block 42 moves upward relative to the moving block 2, the connecting rod 49 will push the bevel gear 33 and the gear 32 to move upward, so that the gear 32 and the rack 31 are disengaged, the gear 32 stops rotating, the eccentric rod 53 stops moving, the connecting rod 54 is reset under the action of the torsion spring, and the stopper 52 is pulled back to close the through hole 202, the cleaning liquid stops spraying, and in the subsequent horizontal movement of the moving block 2 at the heat dissipation hole position, the through hole 202 remains closed to prevent the cleaning liquid from entering the cabinet.

[0046] In some embodiments, scrapers 35 are respectively provided on the left and right sides of the cleaning brush 3, each scraper 35 is slidably cooperated with the moving block 2 along the front-to-back direction, and an elastic member three is provided between the scraper 35 and the moving block 2, and the elastic member three can be a spring, and each scraper 35 is provided with a pointed scraping portion 351 on the side away from the moving block 2.

[0047] Specifically, Figures 1 to 3 As shown, during the horizontal movement of the moving block 2, the scraping portion 351 on the scraper 35 can scrape off the stubborn dirt and dust on the outer wall of the distribution cabinet 6 to improve the cleaning effect. At the same time, through the buffering effect of the elastic member three, when the scraper 35 contacts the outer wall of the distribution cabinet 6, the pressure can be automatically adjusted according to the unevenness of the surface to ensure that the scraper 35 fits tightly against the outer wall and avoid damage to the equipment surface due to hard contact.

[0048] Although the embodiments of the present invention have been shown and described above, it is to be understood that the above embodiments are exemplary and are not to be construed as limitations of the present invention. A person skilled in the art may change, modify, replace and vary the above embodiments within the scope of the present invention.
