[0002] High and low voltage electrical cabinets are devices used to control, protect, and distribute electrical energy. They typically consist of a high-voltage section and a low-voltage section. The high-voltage section receives high-voltage electrical energy from power stations or substations and converts it into low-voltage energy suitable for industrial or commercial use. The low-voltage section distributes the high-voltage energy to various terminal devices or electrical loads.

[0003] During long-term use, it is necessary to regularly maintain the high and low voltage electrical cabinets to ensure the normal operation of their components. This includes cleaning the equipment, checking fasteners, checking cable connections, replacing aging parts, etc.

[0004] However, at present, when performing maintenance and management on electrical components inside high and low voltage electrical cabinets, operability is limited. For deep components, special tools or equipment are required to reach them, which increases the difficulty of maintenance. Moreover, due to limited space, maintenance personnel even need to enter a small space to work, increasing the risk of accidental injury.

[0005] Therefore, there is an urgent need for a high and low voltage electrical cabinet that is easy to maintain to solve the above problems. Utility Model Content

[0006] In view of the deficiencies in the prior art, the present invention aims to provide a high and low voltage electrical cabinet that is easy to maintain, thereby solving the problems raised in the above-mentioned background technology.

[0008] The bracket assembly includes an electrical beam, a draw rod, and a slider. Two sets of draw rods are movably connected inside the electrical beam. Sliders are provided at both ends of the electrical beam. A slide groove is recessed inwardly on the surface of the side plate, and the slider is assembled inside the slide groove.

[0009] The wiring harness assembly includes a cross bar, a pull rod and a square block. The pull rod is movably connected to the middle position inside the cross bar. The left and right ends of the cross bar are connected to the square blocks. The side panel surface is recessed with a rectangular groove, and the square block is assembled inside the rectangular groove.

[0010] As a preferred embodiment, the length of the slide groove is longer than the length of the rectangular groove, which is convenient for reserving longer wires for operation and plays a role in assisting in organizing the wires.

[0011] Five groups of slide grooves and rectangular grooves are provided on the front sides of the inner walls of the two groups of side panels. The opening positions of the ten groups of rectangular grooves are located below the opening positions of the ten groups of slide grooves. Five groups of bracket assemblies and five groups of wiring harness assemblies are installed inside the ten groups of slide grooves and rectangular grooves.

[0012] As a preferred embodiment, the electrical beam has multiple sets of fixing grooves evenly arranged throughout the front and rear surfaces. The fixing grooves facilitate the fixing of electrical components to the front surface of the electrical beam by means of screws or the like.

[0013] As a preferred embodiment, two groups of through holes 1 are formed on the left and right sides of the front surface of the electrical beam, and the pull rods are divided into two groups and movably connected to the inside of the two groups of through holes 1;

[0014] The inner wall of the through hole is recessed to form an annular groove, and a ring is fixed on the front side of the surface of the draw rod. The draw rod is movably connected to the inside of the through hole through the ring. The ring is fitted into the annular groove so that the draw rod can only rotate forward or backward in the through hole, preventing the draw rod from moving back and forth in the through hole.

[0015] As a preferred embodiment, a threaded hole 1 is provided inside the built-in plate behind the through hole 1, and the threaded hole 1 is aligned with the through hole 1;

[0016] The threaded holes are divided into ten groups and are correspondingly opened on the surface of the built-in plate. During actual use, when the electrical beam is pushed to the rear end of the slide groove, the pull rod is rotated. During the rotation of the pull rod, it is horizontally screwed into the threaded hole one, so that the electrical beam is fixed to the front side of the built-in plate.

[0017] As a preferred embodiment, a second through hole is formed in the middle of the front surface of the cross bar, and the second through hole is recessed to form a second annular groove.

[0018] A second collar is fixed on the front side of the pull rod surface, and the pull rod is movably connected to the inside of the second through hole through the second collar. The second collar is fitted inside the second annular groove so that the pull rod can only rotate forward or backward in the second through hole, preventing the pull rod from moving forward and backward in the second through hole.

[0019] As a preferred embodiment, a second threaded hole is opened inside the built-in plate behind the second through hole, and the second threaded hole is aligned with the second through hole;

[0020] The threaded holes are divided into five groups and are correspondingly opened on the surface of the built-in plate. The pull rod can be horizontally screwed into the threaded hole two to fix the cross bar on the front side of the built-in plate.

[0021] As a preferred embodiment, the rear end surface of the pull rod is provided with an external thread 1, the rear end surface of the pull rod is provided with an external thread 2, and the pull rod and the front end of the pull rod are both connected to a handle. By providing a threaded hole 1 on the surface of the pull rod, the insertion rod can be rotated to be screwed into the corresponding threaded hole 1. Similarly, the setting of the threaded hole 2 can rotate the insertion rod 2 to be screwed into the corresponding threaded hole 2, thereby fixing the bracket assembly and the wiring harness assembly respectively on the surface of the built-in plate.

[0022] After adopting the above technical solution, the beneficial effects of the utility model are as follows: the setting of the cross bar allows the wires at the same height of the cross bar to bend backwards, which is convenient for reserving longer wires for operation and plays a role in assisting in organizing the wires. When the cross bar is pulled forward to the front side of the cabinet, the wires between adjacent electrical beams are no longer constrained by the cross bar and bent backwards. Pulling the draw rod can move the electrical beam toward the front side of the cabinet door, at which time the wires are gradually straightened. After straightening, the wires play a role in increasing the moving distance of the electrical beam, which is convenient for staff to get closer to the electrical components to be tested, and there is more space outside the cabinet, which makes it easier to maintain and manage the electrical components.

[0033] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0034] See also Figures 1 to 4 The utility model provides a technical solution: a high and low voltage electrical cabinet that is easy to maintain, comprising: a cabinet body 100, side panels 200 and an internal panel 500, two sets of side panels 200 are symmetrically installed inside the cabinet body 100, an internal panel 500 is fixed to the rear side of the cabinet body 100, and a bracket assembly 300 and a wiring harness assembly 400 are provided between the two sets of side panels 200;

[0035] The bracket assembly 300 includes an electrical beam 310, a draw rod 320, and a slider 330. The electrical beam 310 movably connects two sets of draw rods 320. Sliders 330 are provided at both ends of the electrical beam 310. The surface of the side panel 200 is recessed with a slide groove 340, and the sliders 330 are assembled inside the slide groove 340.

[0036] The wiring harness assembly 400 includes a cross bar 410, a pull rod 420 and a square block 430. The pull rod 420 is movably connected to the middle position inside the cross bar 410. The left and right ends of the cross bar 410 are connected to the square block 430. A rectangular groove 440 is recessed inward on the surface of the side panel 200, and the square block 430 is assembled inside the rectangular groove 440.

[0037] See also Figures 1 to 3 The length of the slide groove 340 is longer than the length of the rectangular groove 440, which is convenient for reserving longer wires for operation and helps to organize the wires.

[0038] Five groups of slide grooves 340 and rectangular grooves 440 are provided on the front sides of the inner walls of the two groups of side panels 200. The positions where the ten groups of rectangular grooves 440 are opened are located correspondingly below the positions where the ten groups of slide grooves 340 are opened. Five groups of bracket assemblies 300 and five groups of wiring harness assemblies 400 are correspondingly assembled inside the ten groups of slide grooves 340 and rectangular grooves 440.

[0039] The electrical beam 310 has multiple sets of fixing grooves evenly arranged throughout the front and rear surfaces. The fixing grooves facilitate the fixing of electrical components to the front surface of the electrical beam 310 by means of screws or the like.

[0040] As the first embodiment of the present invention, during actual use, first insert the sliders 330 at both ends of the electrical beam 310 into the corresponding slide grooves 340, so that the electrical beam 310 is installed horizontally between the two groups of side edges, and then complete the installation of the remaining four groups of electrical beams 310 in sequence according to the above steps. When electrical components are installed on the surface of the electrical beam 310, and the electrical components on the surfaces of the two adjacent groups of electrical beams 310 are connected with wires, insert the square blocks 430 at both ends of the cross bar 410 into the corresponding rectangular grooves 440. When the pull rod 420 is pushed backward, the cross bar 410 will uniformly bend the wires at the same height backward, so that longer wires can be reserved for subsequent operations, reducing the probability of wires falling off when the electrical beam 310 is moved outward, and at the same time playing a role in assisting in organizing the wires to avoid the wires being too long and unable to be bent in a unified direction, causing clutter inside the cabinet 100.

[0041] See also Figures 1 to 4 Two groups of through holes are formed on the left and right sides of the front surface of the electrical beam 310, and the pull rods 320 are divided into two groups and movably connected to the inside of the two groups of through holes.

[0042] An annular groove is formed on the inner wall of the through hole, and a ring is fixed on the front side of the surface of the pulling rod 320. The pulling rod 320 is movably connected to the inside of the through hole through the ring. The ring is fitted into the annular groove so that the pulling rod 320 can only rotate forward or backward in the through hole, preventing the pulling rod 320 from moving back and forth in the through hole.

[0043] A threaded hole 1 is provided behind the through hole 1 and located inside the built-in plate 500 , and the threaded hole 1 is aligned with the through hole 1.

[0044] The threaded holes are divided into ten groups and are correspondingly opened on the surface of the built-in plate 500. In actual use, when the electrical beam 310 is pushed to the rear end of the slide groove 340, the pull rod 320 is rotated. During the rotation process, the pull rod 320 is horizontally screwed into the inside of the threaded hole 1, so that the electrical beam 310 is fixed to the front side of the built-in plate 500.

[0045] A second through hole is formed in the middle of the front surface of the crossbar 410 and extends backwards, and the interior of the second through hole is recessed to form a second annular groove.

[0046] A second ring is fixed on the front side of the pull rod 420 surface, and the pull rod 420 is movably connected to the inside of the through hole 2 through the second ring. The second ring is fitted inside the annular groove 2 so that the pull rod 420 can only rotate forward or reverse in the through hole 2, preventing the pull rod 420 from moving back and forth in the through hole 2.

[0047] A second threaded hole is provided behind the second through hole and inside the built-in plate 500 , and the second threaded hole is aligned with the second through hole.

[0048] The threaded holes 2 are divided into five groups and are correspondingly opened on the surface of the built-in plate 500 . The pull rod 420 can be screwed horizontally into the threaded hole 2 to fix the cross bar 410 on the front side of the built-in plate 500 .

[0049] The rear end surface of the pull rod 320 is provided with an external thread 1, and the rear end surface of the pull rod 420 is provided with an external thread 2. The front ends of the pull rod 320 and the pull rod 420 are both connected to handles. By providing a threaded hole 1 on the surface of the pull rod 320, the insertion rod can be rotated to be screwed into the corresponding threaded hole 1. Similarly, the setting of the threaded hole 2 can rotate the insertion rod 2 to be screwed into the corresponding threaded hole 2, thereby fixing the bracket assembly 300 and the wiring harness assembly 400 respectively on the surface of the built-in plate 500.

[0050] As the second embodiment of the present invention, when an electrical component at a certain location inside the cabinet 100 needs maintenance and management, the maintenance difficulty increases due to the limitations of the internal space of the cabinet 100 and the installation depth of the electrical component. At this time, the pull rods 420 adjacent to the upper and lower parts of the electrical component to be repaired are rotated in turn. During the rotation, the rear end external thread 2 of the pull rod 420 disengages from the corresponding threaded hole 2, so that the corresponding two sets of cross bars 410 are separated from the built-in plate 500, and then the cross bars 410 are pulled forward through the pull rod 420.

[0051] By operating the electrical beam 310 where the electrical component to be repaired is located, the two sets of pulling rods 320 inside it are rotated in turn. During the rotation process, the external thread at the rear end of the pulling rod 320 is disengaged from the threaded hole, thereby separating the electrical beam 310 from the built-in plate 500. At this time, the two sets of pulling rods 320 are held in hand to pull the electrical beam 310 forward. Since the pull rods 420 adjacent to the upper and lower parts of the electrical beam 310 are all pulled forward, the wires between the electrical beams 310 adjacent to the upper and lower parts of the electrical beam 310 are no longer constrained by the cross bar 410 and bent backwards. Therefore, the wires connected to the electrical beam 310 gradually straighten during the movement, which can increase the moving distance of the electrical beam 310.

[0052] Then the electrical beam 310 drives the electrical components to be repaired to gradually move to the front side of the cabinet 100, so that the staff can get closer to the electrical components to be tested, and there is more space outside the cabinet 100, making it easier to maintain and manage the electrical components.

[0053] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
