Description

Technical Field

[0001] This utility model relates to the field of electrical equipment technology, and in particular to a novel high and low voltage switchgear. Background Technology

[0002] High and low voltage switchgear, as the name suggests, is equipment that connects high-voltage or low-voltage cables. Power supply bureaus and substations generally use high-voltage switchgear, which is then stepped down by transformers to low-voltage switchgear, and then to various power distribution boxes. Inside, it is nothing more than an electrical device that integrates some switches, circuit breakers and other protective devices.

[0003] Currently, high and low voltage switchgear contains many electrical components, some of which are installed at low positions. When these components need to be replaced or repaired after a period of use, workers have to bend over or squat for extended periods to complete the replacement or repair. However, prolonged bending or squatting can easily injure the workers' backs or legs and also affect the efficiency of replacing or repairing the electrical components.

[0004] Therefore, it is necessary to provide a new type of high and low voltage switchgear to solve the above-mentioned technical problems. Utility Model Content

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. 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.

[0030] Reference Figure 1-5This utility model provides a novel high and low voltage switchgear, comprising a cabinet body 1, with cabinet doors 18 on both the front and back sides. A device box 2 is movably mounted on the bottom of the cabinet body 1, and a rotating assembly is installed inside the device box 2. A threaded rod 3 is rotatably connected to the top of the inner wall of the cabinet body 1, and a guide rod 4 is fixedly connected between the top and bottom of the inner wall of the cabinet body 1. U-shaped blocks 5 are provided on the outer surfaces of both the threaded rod 3 and the guide rod 4. One U-shaped block 5 is threadedly connected to the threaded rod 3, and the other U-shaped block 5 is movably connected to the guide rod 4. Connecting blocks 6 are slidably connected to opposite sides of the two U-shaped blocks 5, and a mesh plate 7 is fixedly connected between opposite sides of the two connecting blocks 6. The mesh plate 7 is fixedly connected by bolts. There are several grid plates 2 8. By manually turning the knob bolts, one of the grid plates 2 8 and the electrical parts installed on it can be quickly separated from the grid plate 1 7. Through the coordinated use of the cabinet 1, threaded rod 3, guide rod 4, U-shaped block 5, grid plate 1 7, grid plate 2 8, slider 11 and rotating shaft 16, grid plate 1 7, several grid plates 2 8 and the electrical parts to be repaired can be moved out of the cabinet 1. Under the action of the drive motor 1 9, the electrical parts installed at a low position are moved up to a suitable position. This allows workers to replace or repair electrical parts without having to bend over or squat for a long time, thus avoiding back injuries and improving the efficiency of replacing or repairing electrical parts.

[0031] A drive motor 9 is fixedly installed at the bottom of the inner wall of the cabinet 1. The output end of the drive motor 9 is fixedly connected to one end of the threaded rod 3. Slide grooves 10 are provided on both sides of the inner wall of the cabinet 1. Sliding sliders 11 are slidably connected inside the two slide grooves 10. The two sliders 11 are fixedly connected to two U-shaped blocks 5 respectively.

[0032] The U-shaped block 5 has several slots 12 through it, and the connecting block 6 has several slots 13 through it. The slots 12 and 13 are arranged in a linear array. The slots 12 are adapted to the slots 13 respectively. A pin 14 is provided inside one of the slots 12 and one of the slots 13.

[0033] The rotating assembly includes a second drive motor 15, which is fixedly installed inside the device box 2. The output end of the second drive motor 15 is fixedly connected to a rotating shaft 16, and the other end of the rotating shaft 16 is fixedly connected to a turntable 17. The top of the turntable 17 is fixedly connected to the bottom of the cabinet 1. When it is necessary to install or replace electrical parts inside the cabinet 1 from the back of the device, and the space at the back of the device is limited, the rotating assembly can directly rotate the back of the device to the front, improving the convenience of workers installing or replacing electrical parts, and also preventing the cabinet door 18 from obstructing the workers' work due to limited space.

[0034] Working principle: When in use, set appropriate intervals between several devices, and install the required electrical parts on several grid plates 2 8. At the same time, start the drive motor 2 15 to drive the rotating shaft 16 and the turntable 17 to rotate, and drive the cabinet 1 to rotate. With the cooperation of grid plate 1 7 and grid plate 2 8, the power cords connecting the electrical parts can be routed from the side of grid plate 1 7 away from grid plate 2 8, avoiding the accumulation of power cords between electrical parts, improving the neatness of the electrical parts inside the cabinet 1 after installation, and also improving the convenience for workers to find power cords.

[0035] When the device needs to be inspected after a period of use, especially for electrical components installed in a low position, first manually remove the two pins 14 from the two U-shaped blocks 5 and the two connecting blocks 6 respectively, releasing the restriction on the connecting blocks 6. Then manually pull the first grid plate 7, causing it to slide several second grid plates 8 and the electrical components installed on the second grid plates 8 on the two U-shaped blocks 5. After moving the first grid plate 7, several second grid plates 8, and electrical components from the cabinet 1 to a suitable position, re-fix the pins 14 to the overlapping part of the first slot 12 and the second slot 13, and then inspect the connecting blocks 6. The limit switch allows for the direct removal of the grid plate 7, several grid plates 8, and the electrical components mounted on them from inside the cabinet 1 for complete replacement. Then, the drive motor 9 is started, causing the threaded rod 3 to rotate. With the cooperation of the guide rod 4, slide 10, slider 11, pin 14, and connecting block 6, the grid plate 7, several grid plates 8, and the electrical components to be inspected are moved upward along the axial direction of the threaded rod 3 to a suitable position. This allows workers to replace or repair the electrical components mounted on the bottom grid plate 8 without bending or squatting.

[0036] 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. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
