Description

Technical Field

[0001] The utility model belongs to the technical field of power distribution cabinets, in particular to a power distribution cabinet which is convenient to maintain. Background Art

[0002] At present, the distribution cabinets on the market are of various sizes and have very different functions. Some are equipped with intelligent devices. The products also use large-screen LCD touch to conduct comprehensive monitoring of power quality such as current, voltage, frequency, useful power, useless power, and power slope. Users can see the operating status of the power distribution system in the computer room at a glance, so that they can promptly discover safety hazards and avoid risks early. However, this type of distribution cabinet with advanced intelligent devices is relatively expensive and mostly large in size. It is generally not ideal for small occasions or places with little power distribution. Maintenance is also relatively complicated. During the operation of the distribution cabinet, the electrical components in the distribution cabinet are often damaged and need to be maintained in time. After opening the cabinet door, the maintenance staff need to go deep into the distribution cabinet to disassemble and repair the damaged original components. Due to the limited space in the distribution cabinet, the maintenance work of the staff is very difficult, and the staff need to stop the distribution cabinet before they can go deep into the cabinet for maintenance. During the maintenance process, the normal electronic components in the distribution cabinet cannot operate, which greatly reduces the working efficiency of the distribution cabinet.

[0003] The Chinese patent with authorization announcement number CN218415412U discloses a distribution cabinet that is easy to maintain, including a distribution cabinet bottom plate, side plates, cabinet doors, cabinet body and top plate. The bottom plate surface is provided with a slide groove, a limiting wheel groove is provided on one side of the left end of the bottom plate, and a wire hole is provided on the right end of the bottom plate. The bottom plate surface is fixedly connected to a limiting block, and the upper ends of the bottom plate are fixedly connected to side plates. The side plate surfaces are provided with heat dissipation ports, and the inner surfaces of the side plates are fixedly connected with slot plates, and the slot plates are provided with slot holes. The distribution cabinet that is easy to maintain can be maintained and installed by opening the cabinet door and sliding the cabinet body sideways. By slidingly connecting the bottom plate and the cabinet body, a slide groove is provided on the bottom plate to slide the cabinet body apart from the bottom plate and the side plates, so as to solve the problem that the distribution cabinet is inconvenient to operate due to insufficient space.

[0004] However, the above has the following shortcomings:

[0005] Although the above patent adopts a sliding connection method between the bottom plate and the cabinet body, the bottom plate and the cabinet body are slid apart when maintenance is required, so that the internal electrical equipment is exposed to the outside for easy maintenance. However, in actual usage scenarios, the installation space of many distribution cabinets is small, or there are obstacles around them and they are limited, and it is impossible to provide a large space for the cabinet body to slide. It is actually difficult to expose the electrical equipment to provide maintenance space.

[0006] The above patent adopts the method of sliding the bottom plate and the cabinet body to expose the internal picking-up equipment to the outside, providing a larger maintenance space. However, in fact, the side panel area of ​​the above patent and the area of ​​the cabinet body after sliding will block the maintenance personnel, making it impossible for the maintenance personnel to perform maintenance operations freely and flexibly. Utility Model Content

[0007] In order to overcome the deficiencies of the prior art, the technical problem solved by the present invention is that, by arranging pulleys and door panels, the door panels can be opened and moved respectively, thereby effectively avoiding the maintenance space for convenience of personnel maintenance, and will not occupy too much space after opening, avoiding difficulty in opening for maintenance in small or restricted areas. Moreover, as long as the restriction of the limit sleeve on the door panel is released, the position of the door panel can always be adjusted, thereby facilitating the operator to flexibly and variably change the position of the door panel according to actual needs, avoiding the door panel from obstructing and blocking the maintenance space, and making maintenance more flexible and convenient.

[0008] In order to achieve the above-mentioned purpose, the utility model provides the following technical solutions: a power distribution cabinet that is easy to maintain, including a base, characterized in that four columns are symmetrically distributed and fixedly connected to the base, two slide rails are fixedly connected to the upper and lower ends of the four columns, the two slide rails are symmetrical to each other, a plurality of pulleys are slidably connected in each of the slide rails, a door panel is rotatably connected between the two pulleys opposite to each other, a door panel is fixedly connected to each of the door panels, and each of the door panels can be closed to form the outer wall of the power distribution cabinet.

[0009] Furthermore, a limiting plate is fixedly connected between the tops of two adjacent columns and between the bottoms of two adjacent columns, and each limiting plate is tightly fitted to the inner side of the door panel.

[0010] Furthermore, the outer side of the base is slidably connected to a limiting sleeve, and the limiting sleeve can fit tightly with the outer side of each door panel.

[0011] Furthermore, an avoidance groove is provided on each side of the limit sleeve, and a group of first connecting heads are fixedly provided on the outside of the limit sleeve at both sides of each avoidance groove.

DETAILED DESCRIPTION

[0024] In order to enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0025] like Figure 1 、 Figure 2 、 Figure 3 、 Figure 5 and Figure 6As shown, a power distribution cabinet that is easy to maintain includes a base 10, four columns 23 are symmetrically distributed and fixedly connected at the four corners of the base 10, a top cover 13 is fixedly connected to the top of the four columns 23, and multiple groups of mounting frames 24 are evenly distributed and fixedly connected between the four columns 23.

[0026] By providing the mounting bracket 24 , the electrical equipment can be stably installed, and the mounting bracket 24 is unobstructed on all sides, making it convenient for maintenance.

[0027] like Figure 3 、 Figure 4 、 Figure 5 and Figure 6 As shown, two symmetrical slide rails 12 are fixedly connected to the top and bottom of the four columns 23, and multiple pulleys 20 are slidably connected in the two slide rails 12. A rotating shaft 21 is rotatably connected between each two upper and lower opposite pulleys 20, and a door panel 11 is fixedly connected to each rotating shaft 21. All door panels 11 can be assembled together to form the complete outer wall of the distribution cabinet.

[0028] By setting the pulley 20 and the door panel 11, the door panel 11 can be opened and moved respectively, thereby effectively avoiding the maintenance space for personnel to facilitate maintenance, and will not occupy too much space after opening, avoiding difficulty in opening for maintenance in small or restricted areas.

[0029] like Figure 1 and Figure 2 As shown, each door panel 11 is provided with evenly distributed ventilation grooves 14 , and each door panel 11 is provided with a handle 15 at one end away from the rotating shaft 21 .

[0030] By providing the ventilation groove 14 , the gas exchange inside and outside the distribution cabinet can be enhanced, thereby facilitating the heat dissipation of the electrical equipment in the distribution cabinet, and by providing the handle 15 , it is convenient for the operator to operate the door panel 11 .

[0031] like Figure 3 、 Figure 5 and Figure 6 As shown, a plurality of limit plates 22 are fixedly connected between the top and bottom of the four columns 23, and each limit plate 22 can fit with the inner side of the door panel 11. The outer side of the base 10 is slidably connected to a limit sleeve 16, and the limit sleeve 16 can fit with the outer side of the door panel 11.

[0032] By setting the limit plate 22, the flipping direction of the door panel 11 can be limited to prevent the door panel 11 from flipping inward and affecting the integrity of the door panel 11 after being assembled. The limit sleeve 16 can also limit the door panel 11 from flipping outward after being assembled, so that the door panel 11 remains in an assembled state.

[0033] like Figure 1 、 Figure 5 and Figure 6As shown, an avoidance groove 25 is opened on each side of the limit sleeve 16, and a group of symmetrical first connectors 18 are fixedly provided on the outside of the limit sleeve 16 at both sides of each avoidance groove 25. A second connector 19 is fixedly connected to each side of the base 10, and each second connector 19 is slidably connected to the corresponding avoidance groove 25. A lock 17 is installed between each second connector 19 and the corresponding group of first connectors 18.

[0034] By providing the first connector 18 and the second connector 19 , the limiting sleeve 16 can be locked so that the limiting sleeve 16 can limit the door panel 11 from turning outward.

[0035] In this embodiment, initially, the operator installs the present invention at the designated location, and various electrical equipment has been installed and fixed on each group of mounting frames 24. At this time, each door panel 11 is located at the corresponding position of the distribution cabinet and is assembled together to form the outer wall of the distribution cabinet.

[0036] At this time, the first connector 18 and the second connector 19 are locked by the lock 17, and the limit sleeve 16 is restricted at a high position. The limit sleeve 16 wraps the bottom of all the door panels 11 to prevent the door panels 11 from flipping outward, and the internal limit plate 22 is against the inner side of the door panel 11 to prevent the door panel 11 from flipping inward, so that each door panel 11 is restricted and fixed, so that the door panels 11 can be stably assembled as the outer wall of the distribution cabinet.

[0037] When maintenance is required, the operator unlocks and removes each door panel 11, and the first connector 18 and the second connector 19 are no longer restricted and locked, and the limiting sleeve 16 falls directly under the action of gravity, and the limiting sleeve 16 no longer restricts the bottom of the door panel 11.

[0038] Then, the operator can flip outward part of the door panel 11 or all of the door panel 11 through the handle 15 according to actual maintenance needs, and pull the flipped outward door panels 11 to the same side. Since the pulley 20 slides in the slide rail 12, the flipped outward door panels 11 can be gathered in one place, and the internal mounting frame 24 is completely exposed to the outside, which is convenient for maintenance.

[0039] Moreover, as long as the restriction of the limit sleeve 16 on the door panel 11 is released, the position of the door panel 11 can always be adjusted, so that the operator can flexibly change the position of the door panel 11 according to actual needs, avoiding the door panel 11 from obstructing the maintenance space, making maintenance more flexible and convenient.

[0040] After the inspection is completed, the operator resets each door panel 11 so that the door panels 11 are reassembled to form the outer wall of the distribution cabinet. The operator then manually lifts the limit sleeve 16 so that the limit sleeve 16 is again sleeved on the bottom outer side of all door panels 11 to restrict and fix the door panels 11. The operator then reinstalls the lock 17 in the corresponding first connector 18 and second connector 19 in sequence to complete the locking of the limit sleeve 16, preventing unauthorized personnel from opening the door panel 11 and damaging the electrical equipment inside the distribution cabinet.

[0041] The lock 17 is a mature existing technology and will not be described in detail herein.

[0042] For example, certain words are used in the specification and claims to refer to specific components. Those skilled in the art should understand that hardware manufacturers may use different terms to refer to the same component. This specification and claims do not use differences in names as a way to distinguish components, but use differences in the functions of the components as the criteria for distinction.
