[0017] In the technical solution of the present invention:

[0018] Through the sliding cooperation of the second sliding plate, the second lifting groove, the first sliding plate and the first lifting groove, there is no need for workers to stand in the air to work, which effectively avoids the danger of workers at heights, reduces the danger, reduces the difficulty of installing the distribution cabinet, and also reduces the labor workload, thereby improving work progress and improving work performance.

[0019] By positioning the positioning plate, the distribution cabinet is prevented from exceeding the upper end surface of the placement plate during installation and movement, avoiding manual reciprocating adjustment of the position of the distribution cabinet, saving manpower. Moreover, when maintaining the rear side of the distribution cabinet, the positioning plate is adjusted to a vertical state, and thus, it will not block the rear side of the distribution cabinet during maintenance, which can effectively improve work progress and functionality.

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

[0021] By lifting and lowering the second sliding plate and the first sliding plate and assisting with the pedal, the progress of the maintenance work will not be reduced due to the height. Moreover, there is no need to manually move the ladder back and forth or carry the ladder, which makes the maintenance work easy and convenient and improves the safety of the workers.

[0022] By setting the pushing plate and the second spring body, not only can the supporting plate be powered, but also the pressure can be relieved during the downward movement of the placement plate. If the placement plate falls accidentally, the pushing plate and the second spring body can relieve the pressure, thereby effectively avoiding damage to the distribution cabinet and improving the protection of the distribution cabinet.

[0023] By stepping on the first pedal and the second pedal, manual inspection of the power distribution cabinet is simple and convenient. Due to the different heights of the first pedal and the second pedal, the inspection items of the power distribution cabinet are different, thereby making the inspection of the power distribution cabinet more comprehensive.

[0024] In order to prevent the distribution cabinet from falling off or deflecting during lifting, a second protective plate and a first protective plate are provided. The second protective plate is used to guide and cover the distribution cabinet so that it can be stably lifted and moved without deflection. For example, if the distribution cabinet is detached during lifting, the covering and guiding effect of the second protective plate and the inclination of the second pedal allow the distribution cabinet to slide down to the first protective plate stably and smoothly, effectively preventing the distribution cabinet from tipping over, injuring workers, and causing damage to the distribution cabinet due to detachment, thereby improving the safety of workers and the protection of the distribution cabinet, and preventing waste.

[0042] Example 1

[0043] like Figure 1-Figure 11 As shown, an intelligent integrated refined high-voltage power distribution cabinet comprises a first electric pole 1 and a second electric pole 2, wherein a first fixing frame 11 and a second fixing frame 12 are arranged at the lower part of the first electric pole 1, and a first limiting long plate 13 is fixedly connected to one side end of the first fixing frame 11 and the second fixing frame 12, and a first lifting groove 131 is provided on one side of the first limiting long plate 13; a third fixing frame 21 and a fourth fixing frame 22 are arranged at the lower part of the second electric pole 2, and a second limiting long plate 23 is fixedly connected to one side of the third fixing frame 21 and the fourth fixing frame 22, and a second lifting groove 231 is provided on one side of the second limiting long plate 23, and a fixed L-shaped plate 24 is fixedly connected to one side of the upper part of the second limiting long plate 23, and a controller 25 is arranged in the middle of one side of the second limiting long plate 23; a lifting drive device 3, a fixing mechanism 4, a power distribution cabinet 5, and an unfolding device 6 are arranged between the first limiting long plate 13 and the second limiting long plate 23.

[0044] In this embodiment, the lifting drive device 3 includes a first motor 31 fixedly connected to a 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, one end of the first rotating shaft 32 is sleeved with a gear 33, the gear 33 is meshed with a rack plate 34, one side of the rack plate 34 is fixedly connected to a second transmission plate 35, one side of the second transmission plate 35 is fixedly connected to a second sliding plate 36, one side of the second sliding plate 36 is slidably fitted in the second lifting slot 231, and the second transmission plate 35 is fixedly connected to a second sliding plate 36. A placing plate 37 is fixedly connected to the lower end surface of the plate 35, and inclined plates 371 are fixedly connected to both sides of the length of one side surface of the placing plate 37, and a long pressing plate 372 is fixedly connected to the middle of the lower end surface of the placing plate 37, and a first transmission plate 38 is fixedly connected to the side of the placing plate 37 away from the second transmission plate 35, and a first sliding plate 39 is fixedly connected to one side of the first transmission plate 38, and one side of the first sliding plate 39 is slidably fitted in the first lifting slot 131, and a card slot 391 is opened on one side of the upper part of the first sliding plate 39. The first motor 31 is started to drive the first rotating shaft 32 to rotate clockwise. The first rotating shaft 32 is subjected to force and drives the gear 33 to mesh with the rack plate 34 in a clockwise direction. The rack plate 34 is subjected to force to move downward. The rack plate 34 is subjected to force and 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 at the same time. 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. Under the guidance of the first lifting groove 131 and the second lifting plate 231, the placement plate 37 is ensured to move vertically downward. After the placement plate 37 moves downward for a distance, the lower end surface of the pressing long plate 372 is pressed against the upper end surface of the pressing rod 61. The low-pressure rod 61 is subjected to force to move downward and drives the connecting frame 62. The connecting frame 62 is subjected to force through the first connecting frame The connecting rod presses downward on the expansion plate 63. The expansion plate 63 is stressed and its lower part allows the push plate 64 to slide outward inside the expansion groove 651 through the second connecting rod. The push plate 64 is stretched outward by the second spring body 66. During the movement of the push plate 64, the push rod 67, the first support rod 68, and the support plate 695 are driven to move outward at the same time. Under the continued pressure of the long pressing plate 372, the height of the pressing rod 61 gradually decreases, and the distance the push plate 64 slides outward gradually increases until the inclined surface of the bottom of the inclined plate 371 contacts the upper part of the inclined surface of the upper end face of the support plate 695, and the first motor 31 is stopped. This is beneficial to eliminate the need for workers to work at high altitudes, effectively avoiding workers from being exposed to high altitude dangers, reducing the danger, reducing the difficulty of installing the distribution cabinet 5, and reducing the labor workload, thereby improving work progress and improving performance.

[0045] In this embodiment, a side of the second sliding plate 36 is fixedly connected to a movable plate 361, and a side of the movable plate 361 is fixedly connected to a transmission L-shaped plate 362. One side of the upper part of the transmission L-shaped plate 362 is fixedly connected to a limiting slot plate 363. A limiting slot hole 3631 is provided inside the limiting slot plate 363. A guide rod 364 is inserted into the bottom of the limiting slot hole 3631. One end of the guide rod 364 is fixedly connected to a positioning plate 365. One side of the positioning plate 365 is rotatably connected to a first fixed rod 366 through a through hole. One side of the first fixed rod 366 is fixedly connected to a fixed block 367. One side of the fixed block 367 is fixedly connected to one side of the limiting slot plate 363. If the two positioning plates 365 are in a vertical shape, 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 on the outside of the first fixed rod 366. The positioning plate 365 is rotated clockwise or counterclockwise along the inside of the limiting slot 3631 through the guide rod 364 until the guide rod 364 rotates clockwise or counterclockwise to the bottom of the limiting slot plate 363. At this time, the positioning plate 365 is in a horizontal state, which is beneficial to prevent the distribution cabinet 5 from exceeding the end face of the placement plate 37 during installation and movement, and avoids manual reciprocating adjustment of the position of the distribution cabinet 5, saving manpower. Moreover, when repairing the rear side of the distribution cabinet 5, the positioning plate 365 is adjusted to a vertical state, and thus will not block 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 end surface of the placement plate 37. This is conducive to 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 surface of the first fixing frame 11, the output end of the second motor 41 is connected to the 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 surface of one side of a clamping plate 44, one side of the upper end surface of the clamping plate 44 is fixedly connected to a pressure plate 45, one side of the pressure plate 45 is connected to a first spring body 46, one end of the first spring body 46 is fixedly connected to a side surface of the upper part of the first limiting long plate 13, a through opening 47 is opened on one side surface of the upper part of the first limiting long plate 13, and a contact sensor 48 is fixedly connected to the upper end surface of the first limiting long plate 13, one side of the clamping plate 44 passes through the interior of the through opening 47, and one side of the clamping plate 44 is buckled in the interior of the clamping groove 391. The first motor 31 is started to make the second sliding plate 36 slide upward inside the second lifting groove 231, and the first sliding plate 39 slides upward inside the first lifting groove 131, so that the placement 37 and the power distribution cabinet 5 are moved upward until the first sliding plate 39 abuts against the contact sensor 48, and the contact sensor 48 receives a signal and transmits it to the controller 25. The controller 25 receives the signal, 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 is forced to rotate counterclockwise and abuts against one side of the pressing groove 441, so that the card plate 44 is forced to slide to one side. It moves inside the through opening 47, and its card plate 44 drives the pressure plate 45 to one side and is pressed against the first spring body 46. Under the gradual pressure of the cam 43, after one side of the card plate 44 passes through the inside of the through opening 47, its one side of the card plate 44 moves toward the inside of the card slot 391. At this time, the top of the cam 43 has been pressed against one side of the low-pressure slot 441, and at the same time, it has been fixed to the first sliding plate 39, and then fixed to the placement plate 37 and the distribution cabinet 5. The fixation of the card plate 44 can effectively prevent the placement plate 37 and the distribution cabinet 5 from falling downward, and it 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 surface of the pressing rod 61 is in contact with the lower end surface of the pressing long plate 372, and the lower end of the pressing rod 61 is connected to a connecting frame 62, and both sides of the connecting frame 62 are rotatably connected to an unfolding plate 63 through a first connecting rod, and the lower part of the unfolding plate 63 is rotatably connected to a connecting port 641 provided on the pushing plate 64 through a second connecting rod, and the lower end of the pushing plate 64 is slidably matched in an unfolding groove 651 provided on the upper end surface of the bearing block 65, and the unfolding groove 651 is equidistantly provided along the length direction of the bearing block 65 A second spring body 66 is connected between the upper end surface of the bearing block 65, one side surface of the pushing plate 64 and the inner side wall of the expansion groove 651, and a push rod 67 is fixedly connected to the side surface of the pushing plate 64 away from the second spring body 66, and a first support rod 68 is fixedly connected to the upper outer portion of one end of the push rod 67. Both side surfaces 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 a fifth fixing frame 652 and a sixth fixing frame 653. The bearing block 65 is in a suspended state, and a second support rod 681 is fixedly connected to the upper outer portion of one end of the push rod 67. The second motor 41 is started to drive the cam 43 to rotate counterclockwise, so that the cam 43 slides over one side of the pressing groove 441, and the first spring body 46 is used to make one side of the clamping plate 44 detach from the inside of the clamping groove 391, and the second motor 41 is stopped. Without the clamping plate 44 being fixed, the first motor 31 is started to drive the gear 33, so that 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, and then the long pressing plate 372 is pressed against the pressing rod 61, and the pressing rod 61 is subjected to the force to make the two The unfolding plate 63 is unfolded outward, so that the two push plates 64 drive the push rod 67, the first support rod 68, and the support plate 695 to move to both sides simultaneously until the inclined surface at the bottom of the inclined plate 371 contacts the upper part of the inclined surface of the upper end face of the support plate 695, and then the first motor 31 is stopped. This is beneficial for not only providing power to the support plate 695, but also relieving the pressure during the downward movement of the placement plate 37. If the placement plate 37 falls accidentally, the push plate 64 and the second spring body 66 will relieve the pressure, effectively avoiding damage to the distribution cabinet 5 and improving the protection of the distribution cabinet 5.

The lower end surface of the distribution cabinet 5 can be easily checked, which is beneficial to the stepping of the first pedal 693 and the second pedal 698, making manual inspection of the distribution cabinet 5 simple and convenient. Due to the different heights of the first pedal 693 and the second pedal 698, the items to be inspected for the distribution cabinet 5 are different, and the inspection of the distribution cabinet 5 is more comprehensive.

When the support plate 695 moves, the support plate 695 is pulled to one side on the rotating plate 691 through the transmission rod 692 on the first pedal 693. During the gradual pulling, the first pedal 693 and the rotating plate 691 will be pulled downward on the unfolding slide plate 697 by the power of the support plate 695, and slide to one side on the unfolding slide groove 6981, so that the second pedal 698 rotates downward counterclockwise on 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 surface of the second pedal 698 has been pressed against the upper end surface of the first pedal 693, thereby completing the auxiliary and manual maintenance work. It is beneficial that the progress of the maintenance work will not be reduced due to the height, and there is no need to manually move the ladder back and forth, and there is no need to manually carry the ladder, which makes the maintenance work easy and convenient, and also improves the safety of the labor.

[0051] In order 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 is used to guide and cover the distribution cabinet 5 so that it can be stably moved during lifting without shifting. If the distribution cabinet 5 is detached during lifting, the covering and guiding effect of the second protective plate 682 and the inclination of the second pedal 698 allow the distribution cabinet 5 to slide down stably and smoothly to the two first protective plates 6931, thereby effectively preventing the distribution cabinet 5 from tipping over and injuring workers, and also preventing the distribution cabinet 5 from being damaged due to detachment. Therefore, the safety of workers is improved, the protection of the distribution cabinet 5 is improved, and waste is prevented.

[0052] In this embodiment, one side of the second protective plate 682 extends to one side of the support plate 695, and the two second protective plates 682 cover the outer side surfaces of the inclined plates 371 on both sides. This is conducive to stably allowing the power distribution cabinet 5 to move upward through the two second protective plates 682 without deviation.

[0053] An intelligent integrated refined high-voltage distribution cabinet maintenance method, the specific method steps 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 long plate 13, the second limiting long plate 23, the lifting drive device 3, the fixing mechanism 4, and the unfolding device 6;

[0055] S2, installation: through the power of the first motor 31, the placement plate 37 is pressed downward against the upper end of the pressing rod 61, and the support plate 695 is moved to one side until the inclined plate 371 and the support plate 695 are in contact, and the first motor 31 is stopped, and the distribution cabinet 5 is slowly moved along the second pedal 698 and the second protective plate 6982 toward the upper end surface of the placement plate 37 by lifting with a crane, without manual work in the air, thereby improving safety;

[0056] S3, positioning: after adjusting the positioning plate 365 to be horizontal, and the lifted distribution cabinet 5 has reached the upper end surface of the placement plate 37, until one side of the distribution cabinet 5 contacts one side of the positioning plate 365, the distribution cabinet 5 is lowered to the upper end surface of the placement plate 37, so as to avoid manual reciprocating adjustment of the position of the distribution cabinet 5;

[0057] S4, buckle: 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 contacts the contact sensor 48, stop the first motor 31, start the second motor 41, and make the one side of the clamping plate 44 buckle inside the clamping 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 through the controller 25, so that the placement plate 37 moves downward and presses against the pressing rod 61, so that one side of the support plate 695 moves, and also pulls the first pedal 693 to rotate clockwise. The first pedal 693 gradually becomes horizontal until the inclined plate 371 and the support plate 695 collide with each other, and then stop the first motor 31. This effectively eliminates the need for manual movement of the ladder back and forth, and the need for manual carrying of the ladder, making maintenance work easy and convenient.

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

[0060] In the installation of the power distribution cabinet 5, firstly, the first motor 31 is started by the controller 25 to drive the first rotating shaft 32 to rotate clockwise, and the gear 33 is meshed with the rack plate 34. The rack plate 34 is subjected to force and 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, wherein 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 for a certain distance, the long plate 372 is pressed against the pressing rod 61, so that the power of the unfolding plate 63 is transmitted to the pushing plate 64 to slide outward in the unfolding groove 651 and 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 are driven to move outward at the same time. Under the continuous pressure of long plate 372, after inclined plate 371 and support plate 695 collide, first motor 31 is stopped and the placement plate 37 has reached the lowest position of downward movement. Then, the positions of two positioning plates 365 are adjusted to the back of placement plate 37. If two positioning plates 365 are vertical, workers can grasp one side of positioning plate 365 and apply force clockwise or counterclockwise to rotate guide rod 364 clockwise or counterclockwise to the bottom of limit slot plate 363. At this time, the positioning plate 365 is in horizontal state and the working state of positioning plate 365 has been adjusted. Figure 6 As shown in the figure, the distribution cabinet 5 can be lifted upward by a small crane, wherein the lower end surface of the placement plate 37 is less than 45 cm away from the ground. After the distribution cabinet 5 is lifted, the bottom corner of one side of the distribution cabinet 5 can be allowed to contact the upper end surface of the second pedal 698, and then slowly move upward and to the side. In order to prevent the distribution cabinet 5 from falling off or deflecting during lifting, a second protective plate 682 and a first protective plate 6931 are provided. The second protective plate 682 is used to guide and cover the distribution cabinet 5, so that the distribution cabinet 5 is stable during lifting and movement without deflection. Phenomenon, the distribution cabinet 5 continues to move along the upper end surface of the second pedal 698 until the distribution cabinet 5 is guided to the upper end surface of the placement plate 37. After being guided to the upper end surface of the placement plate 37, one side of the distribution cabinet 5 will contact one side of the positioning plate 365. At this time, stop the crane from moving to one side and allow the crane to lower the distribution cabinet 5. The distribution cabinet 5 lands on the upper end surface of the placement plate 37 and is then fixed to the bottom of the distribution cabinet by bolts. When the distribution cabinet 5 is slowly lifted and moved, you only need to manually hold the two sides of the distribution cabinet 5 and place it steadily on the placement plate 37.

[0061] After placement, start the first motor 31 to move the placement plate 37 and the distribution cabinet 5 upward 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. The controller 25 receives the signal, stops the first motor 31, 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 pressing groove 441, allowing the card plate 44 to slide to one side in the opening 47. At the same time, the pressure plate 45 squeezes the first spring body 46. Under the gradual pressure of the cam 43, one side of the card plate 44 moves toward the inside of the card groove 391. At this time, the top of the cam 43 has been pressed against one side of the low-pressure groove 441, and at the same time, it has been fixed to the first sliding plate 39, and then fixed to the placement plate 37 and the distribution cabinet 5. Figure 4 shown.

[0062] When repairing the power distribution cabinet 5, first start the second motor 41 through the controller 25 to drive the cam 43 to rotate counterclockwise, so that the cam 43 slides over one side of the pressing groove 441, and then use the resilience of the first spring body 46 to make one side of the clamping plate 44 disengage from the inside of the clamping groove 391, stop the second motor 41, and after the clamping plate 44 is no longer fixed, start the first motor 31 to drive the gear 33, so that the pressing long plate 372 is pressed against the pressing rod 61, and the pressing rod 61 is subjected to force to make the two expansion plates 63 expand outward, so that the two push plates 64 drive the push rod 67, the first support rod 68, and the support plate 695 to move to both sides at the same time, until the inclined plate 371 and the upper end surface of the support plate 695 collide, then stop the first motor 31, and while the support plate 695 moves, the support plate 695 is pulled to one side on the rotating plate 691 through the transmission rod 692 on the first pedal 693. During the gradual pulling, the first pedal 693 and the rotating plate 691 will follow the power of the support plate 695. The flip plate 696 is pulled downward on the unfolding slide plate 697 and slides to one side on the unfolding slide groove 6981, so that the second pedal 698 rotates downward counterclockwise on 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 surface of the second pedal 698 has been pressed against the upper end surface of the first pedal 693, thereby completing the auxiliary and manual maintenance work. Manual workers do not need to use a ladder, but can directly step on the first pedal 693 and the second pedal 698, and can easily open the distribution cabinet for maintenance.

[0063] When the lower end of the power distribution cabinet 5 needs to be inspected, the first motor 31 does not need to be started, and the original state of the unfolding device 6 (such as Fig.11 ), the worker first steps on the upper end surface of the first protective plate 6931, and then steps on the upper end surface of the second pedal 698, and can easily check the lower end surface of the distribution cabinet 5.
