Description

Technical Field

[0001] This invention relates to the field of power distribution cabinet technology, and in particular to an integrated high-voltage power distribution cabinet and its maintenance method. Background Technology

[0002] High-voltage switchgear refers to electrical products used in power systems for power generation, transmission, distribution, energy conversion, and consumption, performing functions such as switching, control, or protection, with voltage levels ranging from 3.6kV to 550kV. It mainly includes several categories such as high-voltage circuit breakers, high-voltage disconnect switches and grounding switches, high-voltage load switches, high-voltage automatic reclosers and disconnectors, high-voltage operating mechanisms, high-voltage explosion-proof distribution devices, and high-voltage switchgear.

[0003] Currently, before installing distribution cabinets in rural areas, they are fixedly installed on the upper part between two utility poles. However, during installation, because manual operation is only protected by safety ropes, the workers standing on the fixed frame lack stability, resulting in insufficient safety protection for the workers. Moreover, the distribution cabinets are large and heavy, making installation inconvenient and requiring high physical strength, which slows down the installation work. In particular, when repairing distribution cabinets, because the cabinets are installed at a high height, maintenance personnel need to carry ladders themselves and move the ladders back and forth, making the maintenance work inconvenient and reducing work efficiency.

[0004] To address the aforementioned problems, this invention proposes an integrated high-voltage switchgear and a maintenance method. Summary of the Invention

[0005] The purpose of this invention is to provide an integrated high-voltage switchgear and maintenance method, which makes it easier to install and maintain the switchgear.

[0006] This invention provides an integrated high-voltage distribution cabinet, comprising: a first utility pole and a second utility pole, each of which is provided with a lifting track along the height direction; a supporting device is movably connected between the two lifting tracks; the distribution cabinet is placed on the supporting device; a lifting drive device that moves the supporting device up and down along the lifting tracks; and a deployment device located below the supporting device, comprising several movably connected pedals that contact the deployment device when the supporting device descends, causing the pedals of the deployment device to rise.

[0007] Furthermore, a fixing mechanism is provided on the lifting track.

[0008] Furthermore, the lifting track includes a first fixed frame and a second fixed frame, which are respectively spaced apart along the height direction on the first utility pole. A first limiting plate is connected to both the first fixed frame and the second fixed frame, and a first lifting groove is formed on the first limiting plate along the height direction. The lifting track also includes a third fixed frame and a fourth fixed frame, which are respectively spaced apart along the height direction on the second utility pole. A second limiting plate is connected to both the third fixed frame and the fourth fixed frame, and a second lifting groove is formed on the second limiting plate along the height direction.

[0009] Furthermore, the supporting device includes a placement plate, a first transmission plate connected to the side of the placement plate adjacent to the first lifting groove, a first sliding plate connected to the first transmission plate, and the first sliding plate slidably engaging within the first lifting groove; a second transmission plate connected to the side of the placement plate adjacent to the second lifting groove, a second sliding plate connected to the second transmission plate, and the second sliding plate slidably engaging within the second lifting groove; an inclined plate connected to the front side of the placement plate, and an extruded long plate fixedly connected to the bottom of the placement plate.

[0010] Furthermore, the lifting drive device includes a first motor and a rack plate. A fixed L-shaped plate is fixedly connected to one side of the upper part of the second limiting plate. The first motor is connected to the outer wall of the fixed L-shaped plate. The output end of the first motor is connected to a first rotating shaft. A gear is sleeved on one end of the first rotating shaft. The rack plate is connected to the second transmission plate. The rack plate is vertically arranged and meshes with the gear.

[0011] Furthermore, the fixing mechanism includes a second motor, a clamping plate, and a clamping slot; the second motor is connected to the first fixing frame, and the clamping slot is opened on the upper outer side of the first sliding plate; the output end of the second motor is connected to a second rotating shaft, and a cam is fixedly connected to the upper end of the second rotating shaft. The outer ring surface of the cam abuts against a pressing groove opened at the lower end of the clamping plate. A pressure plate is fixedly connected to one side of the upper end of the clamping plate, and a first spring body is connected to one side of the pressure plate. One end of the first spring body is fixedly connected to the upper outer wall of the first limiting elongated plate. An opening is opened on the first limiting elongated plate, and a contact sensor is fixedly connected to the upper end of the first limiting elongated plate. One end of the clamping plate passes through the opening and is inserted into the clamping slot.

[0012] Furthermore, a movable plate is fixedly connected to one side of the second sliding plate, and a transmission L-shaped plate is fixedly connected to one side of the movable plate. A limiting groove plate is fixedly connected to the upper part of the transmission L-shaped plate. A limiting groove hole is opened inside the limiting groove hole. A guide rod is inserted into the limiting groove hole. A positioning plate is fixedly connected to the outer end of the guide rod. A first fixing rod is rotatably connected to one side of the positioning plate through a through hole. A fixing block is fixedly connected to the first fixing rod. The limiting groove plate is fixedly connected to one side of the fixing block.

[0013] Furthermore, the unfolding device includes a pressing rod, the lower end of which is connected to a connecting frame. Both sides of the connecting frame are rotatably connected to unfolding plates via first connecting rods. The lower part of the unfolding plates is rotatably connected to a connecting opening on a push plate via a second connecting rod. The lower end of the push plate slides into an unfolding groove that is engaged with the upper surface of the bearing block. The unfolding groove is equidistantly opened on the upper surface of the bearing block along its length. A second spring body is connected between one side of the push plate and the inner wall of the unfolding groove. A push rod is fixedly connected to the side of the push plate away from the second spring body. One end of the push rod is fixedly connected to a first support rod. Both sides of the bearing block are fixedly connected to the lower ends of the first and second utility poles via a fifth and a sixth fixing frame. The bearing block is suspended in mid-air. A second support rod is fixedly connected to the upper outer part of one end of the push rod.

Both ends of the transmission rod are fixedly connected with flip plates. The upper part of the flip plates is connected to a spreading and closing slide plate through a third connecting rod. The spreading and closing slide plate is slidably fitted into a spreading and closing groove that is locked on the lower end face of the second pedal. The upper end face of the second pedal is fixedly connected to two second protective plates, and one side of the second pedal is connected to the inner two side walls of the upper part of the rotating slot through the third fixed rod.

[0015] The present invention also provides a maintenance method for an integrated high-voltage distribution cabinet, comprising the following steps: S1, fixing: firstly, a first limiting plate, a second limiting plate, a lifting mechanism, a fixing mechanism and an unfolding device are fixedly installed by means of a first fixing frame, a second fixing frame, a third fixing frame, a fourth fixing frame, a fifth fixing frame and a sixth fixing frame;

[0016] S2. Installation: Drive the first motor to press the placement plate downwards against the upper end of the pressure rod, causing the support plate to move to one side until the inclined plate and the support plate touch, then stop the first motor; lift the distribution cabinet and move it along the second pedal and the second protective plate towards the upper surface of the placement plate; S3. Positioning: After adjusting the positioning plate to be level, and the lifted distribution cabinet has reached the placement plate, lower the distribution cabinet onto the placement plate until it touches the positioning plate; S4. Fixing: After installing the distribution cabinet, start the first motor to drive the placement plate upwards until the first sliding plate touches the contact sensor, then stop the first motor; start the second motor to insert the clamping plate into the clamping slot, fixing the placement plate and the distribution cabinet; S5. Maintenance: Start the first motor to drive the placement plate downwards and press against the pressure rod, causing the support plate to move to one side, and pull the pedal clockwise to gradually make it horizontal until the inclined plate and the support plate touch, then stop the first motor.

[0017] In the technical solution of this invention:

[0018] By using the sliding cooperation of the second sliding plate, the second lifting groove, the first sliding plate, and the first lifting groove, it is not necessary for workers to stand at heights to work, effectively avoiding the danger of heights and reducing the risk. This also reduces the difficulty of installing the power distribution cabinet and the amount of manual labor, thereby improving work progress and performance.

[0019] The positioning plate prevents the power distribution cabinet from exceeding the top surface of the placement plate during installation and movement, avoiding the need for manual adjustment of the cabinet's position and saving manpower. Furthermore, by adjusting the positioning plate to a vertical position when maintaining the rear of the power distribution cabinet, it does not obstruct the rear side of the cabinet during maintenance, effectively improving work progress and functionality.

[0020] By fixing the plate, the placement plate and distribution cabinet are effectively prevented from falling downwards, and they are more firmly fixed to the first sliding plate, thereby improving stability and practicality.

[0021] With the lifting and lowering of the second and first sliding plates and the assistance of the pedals, the progress of maintenance work will not be reduced due to height. Moreover, there is no need for manual back-and-forth movement of the ladder or manual carrying of the ladder, making maintenance work easy and convenient, and also improving the safety of personnel.

[0022] By setting up the push plate and the second spring, not only can the support plate be powered, but the pressure can also be eased during the downward movement of the placement plate. If the placement plate falls accidentally, the push plate and the second spring will provide easing pressure, effectively preventing damage to the distribution cabinet and improving its protection.

[0023] By stepping on the first and second pedals, manual inspection of the distribution cabinet becomes simple and convenient. Because the heights of the first and second pedals are different, the items to be inspected for the distribution cabinet are different, thus making the inspection of the distribution cabinet more comprehensive.

[0024] To prevent the distribution cabinet from detaching or shifting during hoisting, a second protective plate and a first protective plate are installed. The second protective plate guides and covers the cabinet, ensuring its stability during hoisting and movement. If the cabinet detaches during hoisting, the second protective plate's covering and guiding effect, along with the tilting of the second footplate, will allow the cabinet to slide smoothly and stably down to the first protective plate. This effectively prevents the cabinet from tipping over, injuring workers, or being damaged due to detachment. This improves worker safety, enhances the protection of the distribution cabinet, and prevents waste. Attached Figure Description

[0042] Example 1

[0043] like Figures 1-11 As shown, an intelligent integrated high-voltage distribution cabinet includes a first utility pole 1 and a second utility pole 2. The lower part of the first utility pole 1 is provided with a first fixing frame 11 and a second fixing frame 12. A first limiting plate 13 is fixedly connected to one side of the first fixing frame 11 and the second fixing frame 12. A first lifting groove 131 is opened on one side of the first limiting plate 13. The lower part of the second utility pole 2 is provided with a third fixing frame 21 and a fourth fixing frame 22. A second limiting plate 23 is fixedly connected to one side of the third fixing frame 21 and the fourth fixing frame 22. A second lifting groove 231 is opened on one side of the second limiting plate 23. A fixed L-shaped plate 24 is fixedly connected to one side of the upper part of the second limiting plate 23. A controller 25 is provided in the middle of one side of the second limiting plate 23. A lifting drive device 3, a fixing mechanism 4, a distribution cabinet 5, and an unfolding device 6 are arranged opposite to the first limiting plate 13 and the second limiting plate 23.

[0044] In this embodiment, the lifting drive device 3 includes a first motor 31 fixedly connected to one side wall of the fixed L-shaped plate 24. The output end of the first motor 31 is connected to a first rotating shaft 32. A gear 33 is sleeved on one end of the first rotating shaft 32. The gear 33 meshes with a rack plate 34. A second transmission plate 35 is fixedly connected to one side of the rack plate 34. A second sliding plate 36 is fixedly connected to one side of the second transmission plate 35. One side of the second sliding plate 36 slides inside the second lifting groove 231. A placement plate 37 is fixedly connected to the lower end face of the plate 35. Inclined plates 371 are fixedly connected to both sides of one side of the placement plate 37. A pressing long plate 372 is fixedly connected to the middle of the lower end face of the placement plate 37. A first transmission plate 38 is fixedly connected to the side of the placement plate 37 away from the second transmission plate 35. A first sliding plate 39 is fixedly connected to one side of the first transmission plate 38. One side of the first sliding plate 39 slides inside the first lifting groove 131. A slot 391 is opened on one side of the upper part of the first sliding plate 39. The first motor 31 is started, driving the first rotating shaft 32 to rotate clockwise. The first rotating shaft 32, under force, drives the gear 33 to mesh with the rack plate 34 clockwise. The rack plate 34, under force, moves downwards. Simultaneously, the rack plate 34 drives the second transmission plate 35, the second sliding plate 36, the placement plate 37, the first transmission plate 38, and the first sliding plate 39 to move downwards. The second sliding plate 36 slides downwards inside the second lifting groove 131, and the first sliding plate 39 slides downwards inside the first lifting groove 131. Guided by the first lifting groove 131 and the second lifting plate 231, the placement plate 37 moves vertically downwards. After the placement plate 37 moves downwards a certain distance, the lower end face of the pressing plate 372 presses against the upper end face of the pressing rod 61. The pressing rod 61, under force, moves downwards, driving the connecting frame 62. The connecting frame 62, under force, passes through the first connecting... The connecting rod presses downward against the unfolding plate 63. Under the force, the lower part of the unfolding plate 63 slides the push plate 64 outward inside the unfolding groove 651 through the second connecting rod. The push plate 64 is stretched outward by the second spring body 66. As the push plate 64 moves, it drives the push rod 67, the first support rod 68, and the support plate 695 to move outward simultaneously. Under the continued pressure of the pressing long plate 372, the height of the pressing rod 61 gradually decreases, and the distance that the push plate 64 slides outward gradually increases until the inclined surface at the bottom of the inclined plate 371 touches the upper part of the inclined surface of the upper end of the support plate 695, at which point the first motor 31 stops. This is beneficial because it eliminates the need for workers to stand at heights to work, effectively avoiding the danger of heights for workers, reducing the risk, reducing the difficulty of installing the distribution cabinet 5, and reducing the amount of manual labor, thereby improving work progress and performance.

[0045] In this embodiment, a movable plate 361 is fixedly connected to one side of the second sliding plate 36, and a transmission L-shaped plate 362 is fixedly connected to one side of the movable plate 361. A limiting groove plate 363 is fixedly connected to one side of the upper part of the transmission L-shaped plate 362. A limiting groove hole 3631 is opened inside the limiting groove plate 3631. A guide rod 364 is inserted through the bottom of the limiting groove hole 3631. A positioning plate 365 is fixedly connected to one end of the guide rod 364. A first fixing rod 366 is rotatably connected to one side of the positioning plate 365 through a through hole. A fixing block 367 is fixedly connected to one side of the first fixing rod 366. The fixing block 367 is fixedly connected to one side of the limiting groove plate 363. If the two positioning plates 365 are vertical, the worker can grasp one side of the positioning plate 365 and apply force clockwise or counterclockwise to rotate the positioning plate 365 clockwise or counterclockwise to the outside of the first fixed rod 366. The positioning plate 365 rotates clockwise or counterclockwise along the inside of the limiting slot 3631 via the guide rod 364 until the guide rod 364 rotates clockwise or counterclockwise to the bottom of the limiting slot 363. At this time, the positioning plate 365 is in a horizontal state, which helps to prevent the distribution cabinet 5 from exceeding the end face of the placement plate 37 during installation and movement, avoiding the need for manual reciprocating adjustment of the position of the distribution cabinet 5, saving manpower. Moreover, when repairing the rear side of the distribution cabinet 5, adjusting the positioning plate 365 to a vertical state will not obstruct the repair of the rear side of the distribution cabinet 5, which can effectively improve the work progress and functionality.

[0046] In this embodiment, a power distribution cabinet 5 is placed on the upper surface of the placement plate 37. This facilitates the lifting and moving of the power distribution cabinet 5, making maintenance and installation convenient.

[0047] In this embodiment, the fixing mechanism 4 includes a second motor 41 fixedly connected to the upper end face of the first fixing frame 11. The output end of the second motor 41 is connected to a second rotating shaft 42. The upper end of the second rotating shaft 42 is fixedly connected to a cam 43. The outer ring surface of the cam 43 presses against a pressing groove 441 opened on the lower end face of one side of the clamping plate 44. A pressure plate 45 is fixedly connected to one side of the upper end face of the clamping plate 44. A first spring body 46 is connected to one side of the pressure plate 45. One end of the first spring body 46 is fixedly connected to one side of the upper part of the first limiting plate 13. A through-hole 47 is opened on one side of the upper part of the first limiting plate 13, and a contact sensor 48 is fixedly connected to the upper end face of the first limiting plate 13. One side of the clamping plate 44 passes through the inside of the through-hole 47, and one side of the clamping plate 44 is snapped into the inside of the slot 391. The first motor 31 is started, causing the second sliding plate 36 to slide upward into the interior of the second lifting groove 231. The first sliding plate 39 slides upward into the interior of the first lifting groove 131, moving the placement 37 and the power distribution cabinet 5 upward until the first sliding plate 39 contacts the contact sensor 48. The contact sensor 48 receives a signal and transmits it to the controller 25. Upon receiving the signal, the controller 25 stops the first motor 31 and starts the second motor 41, driving the second rotating shaft 42 to rotate counterclockwise on the cam 43. The cam 43 rotates counterclockwise under force, contacting one side of the pressing groove 441, causing the clamping plate 44 to slide to one side under force. The plate 44 moves inside the opening 47, and its clamping plate 44 drives the pressure plate 45 to press against the first spring body 46 to one side. Under the gradual pressure of the cam 43, one side of the clamping plate 44 passes through the inside of the opening 47 and moves into the groove 391. At this time, the apex of the cam 43 has pressed against one side of the low-pressure groove 441 and is fixed to the first sliding plate 39. Then, it is fixed to the placement plate 37 and the distribution cabinet 5. The fixing of the clamping plate 44 effectively prevents the placement plate 37 and the distribution cabinet 5 from falling down, and is more firmly fixed to the first sliding plate 39, thereby improving stability and practicality.

[0048] In this embodiment, the unfolding device 6 includes a pressing rod 61. The upper end face of the pressing rod 61 abuts against the lower end face of the pressing plate 372, and the lower end of the pressing rod 61 is connected to a connecting frame 62. Both sides of the connecting frame 62 are rotatably connected to unfolding plates 63 via first connecting rods. The lower part of the unfolding plate 63 is rotatably connected to the connecting port 641 opened on the push plate 64 via a second connecting rod. The lower end of the push plate 64 slides in the unfolding groove 651 that is engaged with the upper end face of the bearing block 65. The unfolding groove 651 is equidistantly opened along the length direction of the bearing block 65. The upper end face of the bearing block 65, one side of the push plate 64 and the inner wall of the unfolding groove 651 are connected to a second spring body 66, and a push rod 67 is fixedly connected to the side of the push plate 64 away from the second spring body 66. A first support rod 68 is fixedly connected to the upper outer part of one end of the push rod 67. Both sides of the bearing block 65 are fixedly connected to the lower ends of the first electric pole 1 and the second electric pole 2 through the fifth fixing bracket 652 and the sixth fixing bracket 653. The bearing block 65 is in a suspended state, and a second support rod 681 is fixedly connected to the upper outer part of one end of the push rod 67. The second motor 41 is started to drive the cam 43 to rotate counterclockwise. After the cam 43 slides past one side of the pressing groove 441, the elasticity of the first spring body 46 causes one side of the clamping plate 44 to disengage from the inside of the clamping groove 391. The second motor 41 is then stopped. Without the clamping plate 44 fixing it, the first motor 31 is started again to drive the gear 33, causing the second sliding plate 36 to slide downward into the inside of the second lifting groove 231 and the first sliding plate 39 to slide downward into the inside of the first lifting groove 131. Then, the pressing plate 372 presses against the pressing rod 61, and the pressing rod 61 is subjected to force to make the two The unfolding plate 63 unfolds outward, causing the two push plates 64 to drive the push rod 67, the first support rod 68, and the support plate 695 to move simultaneously to both sides until the inclined surface at the bottom of the inclined plate 371 touches the upper part of the inclined surface at the top of the support plate 695. Then the first motor 31 stops. This not only provides power to the support plate 695, but also provides pressure relief during the downward movement of the placement plate 37. If the placement plate 37 falls accidentally, it will be relieved by the push plate 64 and the second spring body 66, effectively preventing damage to the distribution cabinet 5 and improving the protection of the distribution cabinet 5.

[0049] When it is necessary to inspect the lower end of the distribution cabinet 5, there is no need to start the first motor 31. Using the original state of the unfolding device 6, the worker first steps on the upper surface of the first protective plate 6931 and then on the upper surface of the second pedal 698. The lower surface of the distribution cabinet 5 can be easily inspected. It is convenient to manually inspect the distribution cabinet 5 by stepping on the first pedal 693 and the second pedal 698. Because the heights of the first pedal 693 and the second pedal 698 are different, the items to be inspected for the distribution cabinet 5 are different, thus making the inspection of the distribution cabinet 5 more comprehensive.

[0050] In this embodiment, the two sides of the bearing block 65 are fixedly connected with second fixing rods 69 at equal intervals along the length direction. One end of the second fixing rod 69 is rotatably engaged with a rotating plate 691 through a third connecting rod. One side of the rotating plate 691 is connected to a first pedal 693 through a transmission rod 692. The first pedal 693 is fixedly connected to both sides along the width direction with a first protective plate 6931. The other side of the pedal 693 is rotatably connected to a rotating slot 6951 opened inside the support plate 695 through a second fixing rod 694. Both ends of the transmission rod 692 are fixedly connected with flip plates 696. The upper part of the flip plate 696 is connected to a spreading slide plate 697 through a third connecting rod. The spreading slide plate 697 is slidably engaged with a spreading groove 6981 that is locked on the lower end face of the second pedal 698. The upper end face of the second pedal 698 is fixedly connected to both sides with second protective plates 682. One side of the second pedal 698 is connected to the inner two side walls of the upper part of the rotating slot 6951 through a third fixing rod 699. As the support plate 695 moves, it is pulled to one side onto the rotating plate 691 via the transmission rod 692 on the first pedal 693. During this gradual pulling, the first pedal 693 and the rotating plate 691, driven by the support plate 695, cause the flipping plate 696 to be pulled downwards onto the unfolding slide plate 697 and slide to one side onto the unfolding groove 6981. This causes the second pedal 698 to rotate counterclockwise downwards onto the outside of the third fixed rod 699 until the support plate 695 stops moving. At this point, the first pedal 693 is horizontal, and one side of the lower end of the second pedal 698 is pressed against the upper end of the first pedal 693, thus completing the auxiliary and manual maintenance work. This design prevents the maintenance work from being slowed down by height, eliminates the need for manual movement of ladders, and reduces the need for manual carrying of ladders, making maintenance work easier and more convenient, while also improving worker safety.

[0051] To prevent the distribution cabinet 5 from falling off or shifting during hoisting, a second protective plate 682 and a first protective plate 6931 are installed. The second protective plate 682 guides and covers the distribution cabinet 5, ensuring it remains stable during hoisting and movement without shifting. If the distribution cabinet 5 detaches during hoisting, the covering and guiding effect of the second protective plate 682 and the tilting of the second footplate 698 allow the distribution cabinet 5 to slide smoothly and stably down onto the two first protective plates 6931. This effectively prevents the distribution cabinet 5 from tipping outward, injuring workers, and causing damage due to detachment. This improves worker safety, enhances the protection of the distribution cabinet 5, and prevents waste.

[0052] In this embodiment, one side of the second protective plate 682 extends onto one side of the support plate 695, and the two second protective plates 682 cover the outer sides of the inclined plates 371 on both sides. This facilitates the stable upward movement of the distribution cabinet 5 through the two second protective plates 682, preventing any deviation.

[0053] A method for overhauling an intelligent integrated high-voltage switchgear, the specific steps of which are as follows:

[0054] S1. Fixing: First, fix the first fixing frame 11, the second fixing frame 12, the third fixing frame 21, the fourth fixing frame 22, the fifth fixing frame 652, and the sixth fixing frame 653 to the first limiting plate 13, the second limiting plate 23, the lifting drive device 3, the fixing mechanism 4, and the unfolding device 6.

[0055] S2. Installation: Powered by the first motor 31, the placement plate 37 is pressed downward against the upper end of the pressing rod 61, causing the support plate 695 to move to one side until the tilting plate 371 and the support plate 695 come into contact. The first motor 31 is then stopped. The distribution cabinet 5 is then slowly moved along the second step 698 and the second protective plate 6982 towards the upper surface of the placement plate 37 by the crane. This eliminates the need for manual work at heights, improving safety.

[0056] S3. Positioning: After adjusting the positioning plate 365 to be horizontal, and the suspended distribution cabinet 5 has reached the upper surface of the placement plate 37, until one side of the distribution cabinet 5 touches one side of the positioning plate 365, the distribution cabinet 5 is lowered down to the upper surface of the placement plate 37. This avoids the need for manual adjustment of the position of the distribution cabinet 5.

[0057] S4. Snap-on: After installing the power distribution cabinet 5, start the first motor 31 to move the placement plate 37 upward until the first sliding plate 38 touches the contact sensor 48. Stop the first motor 31 and start the second motor 41 to snap the plate 44 into the slot 391, thereby fixing the placement plate 37 and the power distribution cabinet 5 and preventing the placement plate 37 and the power distribution cabinet 5 from falling downward.

[0058] S5. Maintenance: First, start the first motor 31 via controller 25 to move the placement plate 37 downward and press against the pressure rod 61, causing the support plate 695 to move to one side. In addition, pull the first pedal 693 to rotate clockwise. The first pedal 693 gradually becomes horizontal until the inclined plate 371 and the support plate 695 come into contact. Then stop the first motor 31. This effectively eliminates the need for manual back-and-forth movement of the ladder or manual carrying of the ladder, making maintenance work easy and convenient.

[0059] The specific working principle of this invention includes the following process:

[0060] In the installation of the distribution cabinet 5, firstly, the controller 25 starts the first motor 31 to drive the first rotating shaft 32 to rotate clockwise. The gear 33 meshes with the rack plate 34. The rack plate 34 is subjected to force and simultaneously drives the second transmission plate 35, the second sliding plate 36, the placement plate 37, the first transmission plate 38, and the first sliding plate 39 to move downward. Among them, the second sliding plate 36 slides downward inside the second lifting groove 231, and the first sliding plate 39 slides downward inside the first lifting groove 131. After the placement plate 37 moves downward a certain distance, it presses against the long plate 372 against the pressing rod 61, so that the power of the unfolding plate 63 is transmitted to the push plate 64 to slide outward in the unfolding groove 651 and is stretched by the second spring body 66. During the movement of plate 64, push rod 67, first support rod 68, second support rod 681, and support plate 695 move outward simultaneously. Under the continued pressure of the pressing plate 372, the first motor 31 stops after the inclined plate 371 and support plate 695 come into contact. The placement plate 37 has reached its lowest downward position. Then, the positions of the two positioning plates 365 are adjusted behind the placement plate 37. If the two positioning plates 365 are vertical, the worker can grasp one side of the positioning plate 365 and apply force clockwise or counterclockwise to rotate the guide rod 364 clockwise or counterclockwise to the bottom of the limiting groove plate 363. At this time, the positioning plate 365 is horizontal, and the working state of the positioning plate 365 has been adjusted. Figure 6 As shown, the distribution cabinet 5 can be lifted upwards using a small crane. The lower end of the placement plate 37 is less than 45cm from the ground. After lifting the distribution cabinet 5, one bottom corner of the distribution cabinet 5 can be placed against the upper end of the second footplate 698. During the slow upward and sideways movement, to prevent the distribution cabinet 5 from falling off or shifting during lifting, a second protective plate 682 and a first protective plate 6931 are provided. The second protective plate 682 guides and covers the distribution cabinet 5, ensuring its stability during lifting and movement without shifting. The phenomenon is that the distribution cabinet 5 continues along the upper surface of the second step 698 until it is guided above the upper surface of the placement plate 37. After being guided to the upper surface of the placement plate 37, one side of the distribution cabinet 5 will abut against one side of the positioning plate 365. At this point, stop the crane from moving to one side and allow the crane to lower the distribution cabinet 5. The distribution cabinet 5 will land on the upper surface of the placement plate 37 and then be fixed to the bottom of the distribution cabinet with bolts. During the slow lifting and movement of the distribution cabinet 5, simply manually support both sides of the distribution cabinet 5 to place it steadily on the placement plate 37.

[0061] After placement, the first motor 31 is started, causing the placement plate 37 and the distribution cabinet 5 to move upwards until the first sliding plate 39 abuts against the contact sensor 48. The contact sensor 48 receives a signal and transmits it to the controller 25. Upon receiving the signal, the controller 25 stops the first motor 31 and starts the second motor 41 to drive the second rotating shaft 42 to rotate counterclockwise on the cam 43. The cam 43 rotates counterclockwise and abuts against one side of the pressure groove 441, causing the clamping plate 44 to slide to one side into the opening 47. At the same time, the pressure plate 45 presses against the first spring body 46. Under the gradual pressure of the cam 43, one side of the clamping plate 44 moves into the groove 391. At this time, the apex of the cam 43 has abutted against one side of the low-pressure groove 441 and is fixed to the first sliding plate 39, and then to the placement plate 37 and the distribution cabinet 5. Figure 4 As shown.

[0062] When repairing the distribution cabinet 5, firstly, the controller 25 starts the second motor 41 to drive the cam 43 to rotate counterclockwise. After the cam 43 slides past one side of the pressure groove 441, the elasticity of the first spring body 46 causes one side of the clamping plate 44 to disengage from the inside of the clamping groove 391. Then, the second motor 41 is stopped. After the clamping plate 44 is no longer fixed, the first motor 31 is started to drive the gear 33, causing the pressure plate 372 to press against the pressure rod 61. The pressure rod 61 is stressed, causing the two unfolding plates 63 to unfold outward. This causes the two pushing plates 64 to move simultaneously to both sides along with the push rod 67, the first support rod 68, and the support plate 695 until the inclined plate 371 and the upper surface of the support plate 695 come into contact. Then, the first motor 31 is stopped. While the support plate 695 is moving, the support plate... 695 is pulled to one side by the transmission rod 692 on the first pedal 693 to the rotating plate 691. During the gradual pulling, the first pedal 693 and the rotating plate 691 will be pulled downward by the power of the support plate 695. The flip plate 696 is pulled downward to the unfolding slide plate 697 and slides to one side to the unfolding slide groove 6981, causing the second pedal 698 to rotate downward counterclockwise to the outside of the third fixed rod 699 until the support plate 695 stops moving. At this time, the first pedal 693 is horizontal, and one side of the lower end of the second pedal 698 has pressed against the upper end of the first pedal 693. Thus, the auxiliary and manual maintenance work is completed. The operator can directly step on the first pedal 693 and the second pedal 698 without the need for a ladder, and can easily open the power distribution cabinet for maintenance.

[0063] When it is necessary to inspect the lower end of the distribution cabinet 5, there is no need to start the first motor 31; the original state of the unfolding device 6 can be utilized (e.g., Figure 11 The worker first steps on the upper surface of the first protective plate 6931, and then on the upper surface of the second pedal 698, which allows for easy inspection of the lower surface of the distribution cabinet 5.

[0064] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
