Each branch circuit is configured according to its needs, such as instruments, automatic controls, motor magnetic switches, and various AC contactors. The main function of a switchgear is to open, close, control, and protect electrical equipment during the power generation, transmission, distribution, and energy conversion processes in a power system. The main components inside a switchgear include circuit breakers, disconnect switches, load switches, operating mechanisms, instrument transformers, and various protective devices.

[0003] In the process of developing this application, the inventors discovered the following problems with the prior art:

[0004] In the current process, the base plate used to install and fix electrical equipment inside the switch cabinet is usually fixed in a certain place inside the cabinet. During use, it is not convenient to adjust the height of the base plate according to the installation requirements. Moreover, since the base plate is fixed inside the cabinet, it is inconvenient and laborious to inspect and replace the electrical equipment.

[0005] Therefore, those skilled in the art have provided a modular power switch cabinet to solve the problems mentioned in the background art. Utility Model Content

[0006] The purpose of this utility model is to overcome the shortcomings of the existing technology and propose a modular cabinet power switch cabinet that can adjust the position of the mounting plate so that the mounting plate can be close to the cabinet door, thereby facilitating the maintenance of the externally fixed electrical equipment. At the same time, the fixed height of the mounting plate can be adjusted according to the installation requirements.

[0007] To achieve the above objectives, the present invention provides the following technical solution:

[0008] A modular power switch cabinet includes a cabinet shell, a fixed frame, and three mounting plates. An adjustment box is fixedly installed on the front end of the upper wall of the cabinet shell. An adjustment mechanism is installed inside the adjustment box. The adjustment mechanism includes two transverse bevel gears and a rotating shaft. Longitudinal bevel gears are fixedly sleeved on both sides of the outer wall of the rotating shaft.

Each of the two sides of the front face of the fixed frame has a first threaded rod rotatably installed. Each of the three mounting plates has a positioning mechanism at the lower end face. Each of the three positioning mechanisms includes a fixed block. Each of the two ends of the outer wall of the three fixed blocks has a second threaded rod fixedly installed at the center. Each of the six second threaded rods has a threaded tube threadedly sleeved on its outer wall.

[0010] Furthermore, two of the six No. 2 threaded rods located on the same horizontal line are respectively slidably disposed inside two slide grooves located on the same horizontal line among the six slide grooves.

[0011] Furthermore, among the six fixed plates, each pair of fixed plates located on the same horizontal line has a fixing groove at both ends and the center of the opposite side. Among the six threaded tubes, each pair of threaded tubes located on the same horizontal line is respectively embedded in the two corresponding fixing grooves located on the same horizontal line.

[0012] Furthermore, the two ends of the rotating shaft are respectively rotatably disposed at the center of both sides of the inner wall of the adjustment box, the two transverse bevel gears are respectively rotatably disposed at both sides of the lower end face of the inner wall of the adjustment box, and the upper ends of the two No. 1 threaded rods respectively rotatably pass through the cabinet door and the adjustment box and are respectively fixedly connected to the center of the lower end face of the two transverse bevel gears.

[0013] Furthermore, the two threaded rods are threaded through the center of the lower end face of three of the six connecting blocks located on the same side.

[0014] Furthermore, each of the three mounting plates has multiple fixing holes on its front end face, and the upper and lower end faces of the fixing frame have multiple screw holes through it.

[0015] Furthermore, a cabinet door is hinged to one side of the front end of the cabinet shell, and the fixed frame is movably disposed inside the cabinet shell.

[0016] This utility model has the following beneficial effects:

[0017] 1. The present invention proposes a modular cabinet power switch cabinet, in which the rotating shaft drives two transverse bevel gears to rotate through two longitudinal bevel gears, thereby driving two threaded rods to rotate synchronously, and then drives six fixed plates to move upward through six connecting blocks, thereby achieving the effect of adjusting the position of the fixed plates, so that the installation height of the electrical equipment fixed on the mounting plate can be adjusted as needed by sliding the mounting plate up and down.

[0018] 2. The present invention proposes a combined cabinet power switch cabinet. By rotating two threaded tubes located on both sides of the same fixed block, the two threaded tubes move towards the fixed block along two No. 2 threaded rods, thereby disengaging the threaded tubes from the fixed groove. At this time, the mounting plate can be pulled to slide the two No. 2 threaded rods along the two sliding grooves to the front end, so that the electrical equipment fixed on the mounting plate is located inside the cabinet shell near the cabinet door, which facilitates the maintenance of the electrical equipment.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Reference Figures 1 to 5 One embodiment provided by this utility model:

[0028] A modular power switch cabinet includes a cabinet shell 1, a fixed frame 4, and three mounting plates 5. An adjustment box 3 is fixedly installed on the upper front end of the outer wall of the cabinet shell 1. An adjustment mechanism 11 is installed inside the adjustment box 3. The adjustment mechanism 11 includes two transverse bevel gears 1101 and a rotating shaft 1103. Longitudinal bevel gears 1102 are fixedly sleeved on both sides of the outer wall of the rotating shaft 1103. The two longitudinal bevel gears 1102 are respectively meshed with the two transverse bevel gears 1101. Three fixing plates 9 are slidably installed on both sides of the fixed frame 4.

[0029] Each of the six fixed plates 9 has a through groove 10 at the center of one side. Each of the three fixed plates 9 has a connecting block 8 fixedly installed at the center of the front face. Each of the two sides of the front face of the fixed frame 4 has a first threaded rod 7 rotatably installed. Each of the three mounting plates 5 has a positioning mechanism 6 at the lower end. Each of the three positioning mechanisms 6 includes a fixed block 602. Each of the two ends of the outer wall of the three fixed blocks 602 has a second threaded rod 603 fixedly installed at the center. Each of the six second threaded rods 603 has a threaded tube 601 threadedly sleeved on the outer wall.

[0030] Specifically, the adjustment mechanism 11 inside the adjustment box 3 can drive the two No. 1 threaded rods 7 to rotate synchronously, which in turn can drive the mounting plate 5 to move up and down, thereby adjusting and fixing the height of the mounting plate 5. The fixing plates 9 on both sides of the fixing frame 4 can fix the position of the mounting plate 5, and the mounting plate 5 can move back and forth along the slide groove 10 through the positioning mechanism 6, making it easy to pull the mounting plate 5 towards the cabinet door 2, thereby facilitating the maintenance, disassembly and installation of the electrical equipment on the mounting plate 5.

[0031] Reference Figure 2 , Figure 3 Of the six No. 2 threaded rods 603, two No. 2 threaded rods 603 located on the same horizontal line are respectively slidably set inside two slide grooves 10 located on the same horizontal line in the six slide grooves 10.

[0032] Specifically, the second threaded rod 603 is slidably set inside the slide groove 10, and the position of the mounting plate 5 can be fixed and adjusted by the cooperation between the second threaded rod 603 and the slide groove 10.

[0033] Reference Figure 2 , Figure 3 , Figure 5 Among the six fixing plates 9, each pair of fixing plates 9 located on the same horizontal line has a fixing groove 12 at both ends and the center of the opposite side. Among the six threaded pipes 601, each pair of threaded pipes 601 located on the same horizontal line is embedded in the two corresponding fixing grooves 12 located on the same horizontal line.

[0034] Specifically, by rotating the threaded tube 601, it moves along the second threaded rod 603 and embeds itself into the fixing groove 12, thereby fixing the position of the mounting plate 5.

[0035] Reference Figure 4 The two ends of the rotating shaft 1103 are respectively rotatably set at the center of the inner wall of the adjusting box 3. The two transverse bevel gears 1101 are respectively rotatably set at the lower end face of the inner wall of the adjusting box 3. The upper ends of the two No. 1 threaded rods 7 respectively rotatably pass through the cabinet door 2 and the adjusting box 3 and are respectively fixedly connected to the center of the lower end face of the two transverse bevel gears 1101.

[0036] Specifically, the rotating shaft 1103 drives the two longitudinal bevel gears 1102 to rotate, which in turn drives the two transverse bevel gears 1101 to rotate, thereby achieving the effect of driving the two No. 1 threaded rods 7 to rotate synchronously.

[0037] Reference Figure 2 , Figure 3 Two No. 1 threaded rods 7 are threaded through the center of the lower end face of three of the six connecting blocks 8 located on the same side.

[0038] Specifically, by rotating the two No. 1 threaded rods 7, the six connecting blocks 8 can be driven to rise or fall synchronously, thereby adjusting and fixing the position of the mounting plate 5.

[0039] Reference Figure 2 , Figure 3 The front faces of the three mounting plates 5 are provided with multiple fixing holes, and the upper and lower ends of the fixing frame 4 are provided with multiple screw holes.

[0040] Specifically, electrical equipment can be installed through the fixing holes on the mounting plate 5, and the fixing frame 4 can be connected and fixed to the cabinet shell 1 through the screw holes on the fixing frame 4.

[0041] Reference Figure 1 , Figure 2 , Figure 3 A cabinet door 2 is hinged to one side of the front face of the cabinet shell 1, and a fixed frame 4 is movably installed inside the cabinet shell 1.

[0042] Specifically, the cabinet door 2 and the cabinet shell 1 can protect the fixed frame 4 located inside the cabinet shell 1.

[0043] Working principle: Rotating the shaft 1103 drives two transverse bevel gears 1101 to rotate via two longitudinal bevel gears 1102, which in turn drives two threaded rods 7 to rotate synchronously to adjust the height of the three mounting plates 5. When it is necessary to inspect and repair the electrical equipment on the mounting plate 5, rotate the threaded tube 601 to disengage it from the fixing groove 12, then pull the mounting plate 5 towards the cabinet door 2, and then rotate the threaded tube 601 again to embed it into the fixing groove 12, thereby fixing the mounting plate 5 inside the cabinet shell 1 near the cabinet door 2, thus greatly expanding the inspection and repair space and facilitating the inspection and maintenance of electrical equipment.

[0044] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
