[0003] In the actual use of the existing comprehensive control cabinet for smart grid, in order to maximize the use of the cabinet space, the electrical elements in the cabinet are usually arranged in a dense manner by stacking them up and down, and the cabinet body is usually designed to have a certain height to meet the integration requirements of multiple elements. When the internal electrical elements need to be repaired or replaced, the upper elements will block the lower elements due to the narrow longitudinal space inside the cabinet body, so it is difficult for the operator to directly touch the target element. At the same time, the height design of the cabinet body makes it necessary to use climbing tools to reach the stacked elements at a high place, while the lower elements need the operator to bend over or even bend down to operate inside the cabinet.

DETAILED DESCRIPTION

[0032] In order to make the skilled in the art better understand the technical solutions of the present application, the present application will be further described in detail below in combination with the drawings.

[0033] As shown in the accompanying Figure 1 to the accompanying Figure 8 , the present application has the following advantages:

[0034] Example 1

[0035] The application provides a comprehensive control cabinet for smart grid, which comprises a cabinet body 1, a storage cavity 3 is formed in the middle of the front end face of the cabinet body 1, a cabinet door 2 is hinged to one side of the front end face of the cabinet body 1 near the opening of the storage cavity 3, fixed frames 4 are fixedly installed on both sides of the inner wall of the storage cavity 3, inner grooves 5 are formed in the fixed frames 4, gear wheels 6 are arranged in the inner grooves 5 in parallel at equal intervals, and guide mechanisms are arranged on one side of the middle of the gear wheels 6 and extend to the outside of the fixed frames 4.

[0036] The guide mechanism comprises support guide rails 7, which are arranged on one side of the middle of the gear wheels 6 and extend to the outside of the fixed frames 4, a guide sliding groove 8 is formed in one end of the support guide rails 7, mounting brackets 9 are installed between the two support guide rails 7 arranged in a left-right symmetrical mode, and guide convex strips 10 are fixedly installed on the outer surfaces of the mounting brackets 9 and extend to the inside of the guide sliding groove 8.

[0037] Fixed handles 11 are fixedly installed at the bottom of the front end face of the mounting brackets 9.

[0038] The fixed frames 4 are also provided with lifting mechanisms, which are used for controlling the rotating angle of the support guide rails 7.

[0039] Fixed baffle plates 15 are fixedly installed on the upper surfaces of the support guide rails 7 at equal intervals, bearing supports 16 are arranged on the upper surfaces of the support guide rails 7 near the fixed baffle plates 15, movable baffle plates 17 are rotatably installed in the bearing supports 16, fixed plates 18 are fixedly installed on the outer surfaces of the mounting brackets 9 near the hinged positions, mounting seats 19 are arranged at the top of one end of the fixed plates 18, limit hooks 20 are rotatably installed in the mounting seats 19, stretching springs 21 are installed on the outer surfaces of the limit hooks 20, and one end of the stretching springs 21 is connected to the bottom of the outer surface of the fixed plate 18.

[0040] The movable baffle plate 17 is arranged on the upper surface of the fixed baffle plate 15, the limit hook 20 is hooked to the top of the outer surface of the fixed baffle plate 15, and the fixed baffle plate 15 and the limit hook 20 are clamped to each other.

[0041] Working principle: firstly, when the staff needs to overhaul the electrical components in the cabinet, the cabinet door 2 is opened to expose the mounting bracket 9 in the storage cavity 3, at this time, the mounting bracket 9 is in the initial position, the movable baffle plate 17 is arranged on the outer surface of the fixed baffle plate 15 arranged in an inclined mode, the limit hook 20 is not clamped to the fixed baffle plate 15 under the natural elastic force of the stretching spring 21, and the sliding of the mounting bracket 9 is only preliminarily limited by the movable baffle plate 17.

[0042] Then, the worker holds the fixing handle 11 at the front end of the mounting bracket 9 and pulls the mounting bracket 9 forward, so that the guide protrusions 10 on both sides of the mounting bracket 9 slide smoothly along the guide sliding grooves 8 of the support guide rails 7. Since the two are well fitted, the sliding process is smooth and the mounting bracket 9 cannot be separated from the support guide rails 7. At the same time, the mounting bracket 9 drives the limiting hooks 20 on the fixed plates 18 and the mounting seats 19 on both sides to move synchronously. When the limiting hooks 20 move with the mounting bracket 9, they slide along the inclined surface of the movable baffle 17. Since the movable baffle 17 is arranged on the fixed baffle 15, the limiting hooks 20 will not directly contact the fixed baffle 15, ensuring that the mounting bracket 9 can be smoothly pulled out.

[0043] Then, if it is desired to lock the mounting bracket 9 at a certain pull-out length to facilitate maintenance and prevent the pull-out length from being too long to affect efficiency, the worker first pushes the mounting bracket 9 inward by a small distance. When the limiting hooks 20 move inward with the mounting bracket 9, they will push the movable baffle 17 to rotate around the bearing support 16, so that the movable baffle 17 and the inclined fixed baffle 15 are separated from each other. Then, the mounting bracket 9 is pulled outward to the target length again. The extension spring 21 generates a restoring force due to the movement of the limiting hooks 20, drives the limiting hooks 20 to rotate downward, and hooks the inclined fixed baffle 15, thereby locking the mounting bracket 9 at the current pull-out length in the inclined state.

[0044] Since the support guide rails 7 are provided with a plurality of fixed baffles 15 and matched movable baffles 17 at equal intervals along the length direction, the worker can repeatedly perform the "inward push-outward pull" operation to make the limiting hooks 20 hook the fixed baffles 15 at different positions, so as to adjust the pull-out length of the mounting bracket 9 and adapt to the operation requirements of different maintenance scenes, avoiding the problem that the overall pull-out length of the mounting bracket 9 is too long to cause insufficient operation space and affect the maintenance efficiency.

[0045] Finally, after the maintenance is completed, the worker disengages the limiting hooks 20 from the fixed baffles 15 and pushes the mounting bracket 9 back to its original position. The movable baffle 17 is arranged on the fixed baffle 15 again under the action of its own gravity or slight external force. The cabinet door 2 is closed, and the entire operation process is completed.

[0046] Embodiment Two

[0047] This embodiment is basically the same as the previous embodiment, except that the lifting mechanism includes a movable frame 12. The movable frame 12 is movably arranged inside the inner groove 5 and extends to the outside of the cabinet 1. One end of the movable frame 12 is fixedly installed with a rack plate 13 near the position of the gear 6. The outer surface of the cabinet 1 is provided with a driving part 14 near the movable frame 12. The output end of the driving part 14 is connected to the middle position of the top of the movable frame 12.

[0048] The movable frame 12 and the driving part 14 are located inside the protective frame 26 fixedly installed on the upper surface of the cabinet 1.

[0049] The rack plate 13 is provided with a plurality of teeth at one end, and the gear 6 is provided with a plurality of teeth on one side of the outer surface close to the front end surface of the rack plate 13. The gear 6 and the rack plate 13 are in meshing engagement.

[0050] Working principle: first, the staff needs to adjust the angle of the support rail 7 to adapt to the maintenance requirements, first confirm that the protective frame 26 on the upper surface of the cabinet 1 has wrapped the movable frame 12 and the driving part 14, so as to avoid the collision of external force with the transmission components during operation; the staff operates the driving part 14, the output end of the driving part 14 drives the movable frame 12 to move up and down along the inner groove 5 of the fixed frame 4, the rack plate 13 at one end of the movable frame 12 is in meshing engagement with the gear 6 in the inner groove 5, the rack plate 13 transmits power through the teeth, and drives the gear 6 to rotate around its own rotating shaft; because the gear 6 is fixedly connected with the support rail 7, the gear 6 rotates synchronously to drive the support rail 7 to rotate, so that the fixed baffle 15 on the support rail 7 is in an inclined state (the angle is adapted to the maintenance operation);

[0051] Then, the staff holds the fixed handle 11 of the mounting bracket 9 and pulls the mounting bracket 9 forward, the guide protrusions 10 on both sides of the mounting bracket 9 slide along the guide sliding groove 8 of the support rail 7, the mounting bracket 9 drives the limiting hook 20 to move synchronously, and the limiting hook 20 smoothly moves along the inclined surface of the movable baffle 17 initially arranged on the fixed baffle 15 without jamming phenomenon;

[0052] Then, if it is necessary to lock the pulled-out length of the mounting bracket 9, the staff first pushes the mounting bracket 9 inward by a small distance, the limiting hook 20 pushes the movable baffle 17 to rotate around the bearing support 16, so that the movable baffle 17 is separated from the inclined fixed baffle 15; then, the mounting bracket 9 is pulled outward to the target length, the extension spring 21 drives the limiting hook 20 to be hooked downward on the inclined fixed baffle 15, and the locking of the mounting bracket 9 is completed. By cooperation of the plurality of fixed baffles 15 and movable baffles 17 on the support rail 7, the pulled-out length of the mounting bracket 9 can be adjusted, so as to avoid that the pulled-out length is too long to affect the maintenance efficiency;

[0053] In this process, the meshing transmission of the gear 6 and the rack plate 13 is stable, the angle adjustment of the support rail 7 is accurate, the limiting hook 20 can be stably hooked due to the inclined arrangement of the fixed baffle 15, and the locking failure caused by angle deviation will not occur; at the same time, the protective frame 26 always protects the transmission components, so as to avoid external interference. After the maintenance is completed, the staff first unlocks the mounting bracket 9 and resets it, then reversely operates the driving part 14, so that the support rail 7 returns to the initial angle, and the cabinet door 2 is closed.

[0054] Example three:

[0055] The embodiment is basically same as the last embodiment, the difference is that the inner wall of the storage cavity 3 is fixedly installed with a guide limiting frame 22 at the corresponding position of the support rail 7, a plurality of limiting holes 23 are formed in one side of the inner wall of the guide limiting frame 22, a limiting sleeve 24 is fixedly installed on one side of the middle part of the outer surface of the support rail 7, and a limiting plug 25 is inserted into the limiting hole 23;

[0056] The outer diameter of the limiting sleeve 24 is smaller than the distance between the inner wall of the guide limiting frame 22, and one end of the limiting sleeve 24 extends into the guide limiting frame 22, and the guide limiting frame 22 and the limiting sleeve 24 are embedded with each other;

[0057] The limiting sleeve 24 and the limiting hole 23 have the same inner diameter, one end of the limiting plug 25 extends into the limiting sleeve 24 through the limiting hole 23, and the limiting hole 23 and the limiting sleeve 24 are clamped with the limiting plug 25.

[0058] Working principle: first, when the staff needs to adjust the angle of the support rail 7, hold the end of the limiting plug 25 and pull it out of the limiting hole 23 of the guide limiting frame 22 to remove the angle limit of the support rail 7; because the limiting sleeve 24 and the guide limiting frame 22 are embedded with each other, and the outer diameter of the limiting sleeve 24 is smaller than the distance between the inner wall of the guide limiting frame 22, the staff can smoothly rotate the support rail 7, so that the fixed baffle 15 on the support rail 7 is in an inclined state, which adapts to the maintenance operation requirement, and the guide limiting frame 22 plays a guiding role on the limiting sleeve 24 during rotation to prevent the support rail 7 from deviating;

[0059] Then, the staff holds the fixed handle 11 of the mounting bracket 9 and pulls the mounting bracket 9 forward, the guide ribs 10 on both sides of the mounting bracket 9 slide along the guide sliding groove 8 of the support rail 7, the limiting hook 20 is driven by the mounting bracket 9 to move synchronously, and the limiting hook 20 moves along the inclined surface of the movable baffle 17 arranged on the fixed baffle 15, because the movable baffle 17 is closely attached to the fixed baffle 15, the movement of the limiting hook 20 is smooth and has no jamming;

[0060] Then, if you need to lock the pull-out length of the mounting bracket 9, first push the mounting bracket 9 inward by a small distance, the limiting hook 20 pushes the movable baffle 17 to rotate around the bearing support 16, so that the movable baffle 17 is separated from the inclined fixed baffle 15; then pull the mounting bracket 9 outward to the desired length, the restoring force of the tension spring 21 drives the limiting hook 20 to rotate downward and hooks on the inclined fixed baffle 15 to achieve the locking of the mounting bracket 9; because a plurality of fixed baffles 15 and movable baffles 17 are arranged on the support rail 7 along the length direction, the staff can adjust the pull-out length of the mounting bracket 9 by selecting different positions of the fixed baffles 15, so as to avoid the inconvenience caused by pulling out too long and affecting the maintenance efficiency;

[0061] Finally, the staff will limit the insertion of the rod 25 through the guide limiting frame 22 corresponding to the limiting hole 23, inserted into the limiting sleeve 24, fixed angle of the support rail 7; after the maintenance is completed, the limiting insertion rod 25 is pulled out first, the installation support 9 is unlocked and reset, then the support rail 7 is adjusted to the initial angle, the limiting insertion rod 25 is inserted back to fix, the cabinet door 2 is closed, and the whole maintenance process is completed.

[0062] The above has described certain exemplary embodiments of the present application by way of illustration only, and it is needless to say that the described embodiments can be modified in various ways without departing from the spirit and scope of the present application for those skilled in the art. Therefore, the above drawings and descriptions are illustrative in nature and should not be understood as limiting the scope of protection of the claims of the present application.
