The limit switch 10 is rotatably mounted on the side wall of the mounting plate 1, and the limit switch 10 is electrically connected to each of the lighting rods 8. The limit switch 10 is arranged facing outward inside the control cabinet; when the cabinet door of the control cabinet is open, the limit switch 10 is in the conducting state; when the cabinet door of the control cabinet is closed, pressing the limit switch 10 disconnects the circuit.

[0032] The following is an example:

[0033] like Figures 1-3 As shown in this embodiment, a layered lighting device for the control room of an underground powerhouse in a hydropower station includes a mounting plate 1. Three sets of U-shaped adjusting seats 3 are arrayed along the length of one side wall of the mounting plate 1. The adjusting seats 3 provide mounting positions for screws 4 and guide rods 5. A screw 4 is installed inside the adjusting seat 3, and a parallel guide rod 5 is provided on one side of the screw 4. A knob 9 is connected to the top of the screw 4; rotating the knob 9 causes the screw 4 to rotate. Screw blocks 6 are fitted onto both the screw 4 and the guide rods 5. During the rotation of the screw 4, the screw blocks 6, guided by the threads and the guide rods 5, move the lighting rods 8, thereby adjusting the position of the lighting rods 8 according to the space inside the control cabinet. A support plate 7 is installed on one side wall of the screw blocks 6, and the lighting rods 8 are fixed on one side wall of the support plate 7. The lighting rods 8 on the support plate 7 can provide layered lighting inside the control cabinet, facilitating maintenance work by staff. A limit switch 10 is installed on the side wall of the mounting plate 1 opposite to the adjusting seats 3, which can control the opening and closing of the lighting rods 8.

[0034] like Figures 1-3As shown, in this embodiment, the adjusting seat 3 is welded to the mounting plate 1, the screw 4 is rotatably installed in the adjusting seat 3, the guide rod 5 is welded in the adjusting seat 3, one end of the knob 9 is fixedly connected to the screw 4, the screw block 6 is threadedly connected to the screw 4, and the guide rod 5 passes through the screw block 6.

[0035] like Figures 1-3 As shown, in this embodiment, one end of the support plate 7 is mounted on the screw block 6 by screws, the lighting rod 8 is fixed on the support plate 7 by screws, the limit switch 10 is rotatably mounted on the mounting plate 1, the limit switch 10 is electrically connected to the lighting rod 8, and the mounting plate 1 has fixing holes 2 at both the upper and lower ends, the fixing holes 2 on the mounting plate 1 facilitate fixing the device in the control equipment.

[0036] The specific implementation process of this embodiment is as follows:

[0037] In use, firstly, the mounting plate 1 is installed on the edge of the side wall near the hinge inside the control cabinet through the fixing hole 2. Then, the knobs 9 of each lighting unit are rotated, thereby driving the screw 4 to rotate. During the rotation of the screw 4, the screw block 6, guided by the thread and the guide rod 5, drives the lighting rod 8 to move. The position of the lighting rod 8 is then adjusted according to the space inside the control cabinet, so that the lighting rods 8 of each lighting unit are distributed at different heights inside the control cabinet, achieving illumination of the control cabinet interior. In this application, the position of the lighting rod 8 of each lighting unit is adjustable, thus flexibly adapting to the lighting needs of different control cabinets and improving the adaptability of the device.

[0038] Next, connect the external power supply. When the cabinet door is open, the limit switch 10 is in the pop-out state, meaning it is in the conducting state, and the lighting rods 8 of each lighting unit are on. When the cabinet door is closed, the door presses down on the limit switch 10, breaking the circuit and turning off the lighting rods 8. Therefore, when maintenance is required inside the control cabinet, opening the door causes the limit switch 10 to automatically pop back, connecting the circuit and automatically turning on the lighting rods 8 to provide layered lighting inside the control cabinet, facilitating maintenance work. After maintenance is completed, closing the cabinet door presses down on the limit switch 10, breaking the circuit and automatically turning off the lighting rods 8, thus achieving automatic on / off operation of the lighting rods 8.
