[0030] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.
[0031] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.
[0032] Please see Figures 1 to 4An outdoor transformer substation includes: a housing 1, a battery 5, a door 7, a limiting assembly, and an unfolding assembly. A supporting connecting frame 2 is fixedly connected inside the housing 1. A drawer 3 for storing maintenance tools is slidably connected inside the connecting frame 2. A mounting plate 4 is fixedly connected to the top of the drawer 3. Electrical equipment is installed on the outward-facing side of the mounting plate 4. A battery 5 for nighttime maintenance of the electrical equipment is installed at the bottom inside the housing 1. A light 6 for illumination is installed inside the mounting plate 4. A contact switch is installed inside the housing 1. A rotatable switch is installed at the opening of the housing 1. The cabinet door 7 has a pull rod 8 rotatably connected inside. One end of the pull rod 8 is rotatably connected to one side of the drawer 3. A limiting component for limiting is installed between the drawer 3 and the cabinet body 1. A rotatable unfolding component is installed between the cabinet body 1 and the lamp 6. A clearance groove 9 is opened at the bottom of the connecting frame 2. The battery 5, the lamp 6 and the contact switch are electrically connected. The outer surface of the cabinet body 1 is coated with an anti-corrosion coating to improve the corrosion resistance and service life of the cabinet body 1. The contact switch is an inductive switch. When the cabinet door 7 is opened, the drawer 3 contacts the contact switch and is automatically triggered to turn on the lamp 6 to provide lighting.
[0033] It should be noted that the pull rod 8, which is rotatably connected inside the cabinet door 7, moves as the cabinet door is opened, thereby causing the drawer 3 to slide inside the connecting frame 2;
[0034] The sliding of drawer 3 not only makes it easier for maintenance personnel to take out the necessary maintenance tools, but also moves the mounting plate 4 and the electrical equipment on it toward the door 7, providing a more convenient operating space for maintenance.
[0035] Please see Figure 3-4 The drawer 3 has a groove 21, a connecting plate 22, an L-shaped rod 23, a slot 24, and a spring 25. The drawer 3 has a groove 21 inside, and a connecting plate 22 is slidably connected to the inner wall of the groove 21. A spring 25 is fixedly connected between the groove 21 and the connecting plate 22. An L-shaped rod 23 is fixedly connected to the axis of the connecting plate 22. A slot 24 is opened at the bottom of the box 1. One end of the L-shaped rod 23 is inserted into the slot 24, and the other end of the L-shaped rod 23 extends out of the groove 21.
[0036] It should be noted that as drawer 3 moves, the L-shaped insert 23 installed inside the drawer gradually approaches and eventually inserts into the slot 24 at the bottom of the box 1 under the action of spring 25.
[0037] The insertion of the L-shaped plug 23 achieves the limiting and fixing between the drawer 3 and the cabinet 1, effectively preventing the cabinet door 7 from being accidentally closed or opened due to wind force during maintenance, especially in windy conditions, thus ensuring the safety of maintenance personnel and the stable operation of the equipment.
[0038] Please see Figure 1-4The mounting plate 4 has a placement groove 31, a support rod 32 and a tension spring 33. The mounting plate 4 has a placement groove 31 inside. The inner wall of the placement groove 31 is rotatably connected to the support rod 32. The end of the support rod 32 near the door 7 is fixedly connected to the lamp 6. The inner side of the box 1 is fixedly connected to the end of the support rod 32 away from the lamp 6 and the tension spring 33.
[0039] It should be noted that as the mounting plate 4 moves toward the door 7, the support rod 32 inside the mounting plate gradually unfolds under the action of the tension spring 33.
[0040] One end of the support rod 32 is fixedly connected to the lamp 6, and the other end is connected to the inside of the housing 1. Under the tension of the tension spring 33, the support rod 32 forms a lever, rotating the lamp 6, which was originally parallel to the mounting plate 4, to a vertical position.
[0041] The working principle of the outdoor transformer box provided by this utility model is as follows:
[0042] Overall operation process:
[0043] When it is necessary to inspect and maintain an outdoor transformer box, the maintenance personnel should first open the box door 7;
[0044] The pull rod 8, which is rotatably connected inside the box door 7, moves as the box door is opened, thereby causing the drawer 3 to slide inside the connecting frame 2;
[0045] The sliding of drawer 3 not only makes it easier for maintenance personnel to take out the necessary maintenance tools, but also moves the mounting plate 4 and the electrical equipment on it toward the door 7, providing a more convenient operating space for maintenance.
[0046] Working principle of limit components:
[0047] As drawer 3 moves, the L-shaped insert 23 installed inside the drawer gradually approaches and eventually inserts into the slot 24 at the bottom of the box 1 under the action of spring 25;
[0048] The insertion of the L-shaped plug 23 achieves the limiting and fixing between the drawer 3 and the cabinet 1, effectively preventing the cabinet door 7 from being accidentally closed or opened due to wind force during maintenance, especially when it is windy, thus ensuring the safety of maintenance personnel and the stable operation of the equipment.
[0049] How a lighting system works:
[0050] When drawer 3 moves to the limit position, one edge of drawer 3 will contact the electric switch;
[0051] The triggering of the electric shock switch connects the circuit between the battery 5 and the lamp 6, allowing the battery to provide power to the lamp, which then lights up.
[0052] In this way, maintenance personnel can obtain sufficient lighting while opening the cabinet door for maintenance, without having to carry additional lighting tools, thus improving the efficiency and safety of maintenance.
[0053] How the expanded component works:
[0054] As the mounting plate 4 moves toward the door 7, the support rod 32 inside the mounting plate gradually unfolds under the action of the tension spring 33;
[0055] One end of the support rod 32 is fixedly connected to the lamp 6, and the other end is connected to the inside of the housing 1; under the tension of the tension spring 33, the support rod 32 forms a lever, rotating the lamp 6, which was originally parallel to the mounting plate 4, to a vertical position.
[0056] The vertical arrangement of lamp 6 not only provides a wider lighting range, but also avoids the light being blocked by mounting plate 4 or other equipment, thus ensuring sufficient lighting in the maintenance area.
[0057] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
