Technical Field

[0001] This utility model relates to the field of power wells, specifically a lighting device for power wells. Background Technology

[0002] Power wells are an important component of underground power facilities, typically vertical or horizontal underground structures built of concrete or composite materials, used for the centralized laying, inspection, and maintenance of cables. Their main structure includes a well shaft, cover, supports, and a waterproof layer; the depth and dimensions are designed according to the number of cables and voltage levels. The main functions of power wells include protecting cables from mechanical damage, providing waterproofing and moisture protection, and offering operational space for line branching and turning, while facilitating access for technicians for inspections or emergency repairs. Modern power wells are often equipped with intelligent monitoring systems to monitor temperature, humidity, water level, and gas concentration in real time, ensuring urban power supply safety. As a critical node in the power grid, power wells are widely used in municipal construction, rail transit, and residential power distribution networks; their rational layout directly affects the reliability of the power system and the utilization rate of urban underground space.

[0003] For example, patent application CN 221001134 U discloses an electrical well, comprising a well body and a well cover, the well cover covering the opening of the well body; a limiting groove is formed around the opening of the well body, the limiting groove being able to be engaged with the side wall of the outer edge of the well cover; a drainage ditch is formed around the side wall of the limiting groove away from the opening, the drainage ditch being collinear with the axis of the limiting groove, and the bottom of the drainage ditch being connected to an underground sewage pipe network; a sealing ring is formed around the side wall of the well cover near the well body, the axis of the sealing ring being collinear with the axis of the well cover, the sealing ring being able to abut against the inner wall of the well body. This application has the effect of reducing the possibility of damage to cables in electrical wells due to water immersion.

[0004] However, existing power wells do not have lighting devices installed inside, which makes it inconvenient for maintenance personnel to carry lights when entering the power wells; therefore, there is an urgent need in the market to develop a lighting device for power wells to help people solve the existing problems.

Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] Please see Figure 1-5 An embodiment of this utility model provides a lighting device for an electric well, including a fixed base 1 and an electric well 6. The fixed base 1 is fixedly connected to the inner wall of the electric well 6 by a plurality of expansion bolts 101, so that the fixed base 1 and the electric well 6 are stably connected. The fixed base 1 is installed at the upper end of the rear end of the inner wall of the electric well 6. The front end of the fixed base 1 is rotatably connected to a first C-shaped rotating base 2. The front end of the first C-shaped rotating base 2 is rotatably connected to a support arm 3. The front end of the support arm 3 is rotatably connected to a battery box 4. A control switch 404 is fixedly connected to the middle of the upper end of the battery box 4. A lamp holder 5 is fixedly connected to the front end of the battery box 4. An LED tube 501 is fixedly connected to the lamp holder 5.

[0025] Please see Figure 3 , Figure 4 and Figure 5A circular fixing post 102 is fixedly connected to the middle of the front end of the fixed base 1. The front end of the circular fixing post 102 is connected to the rear end of the first C-shaped rotating base 2 through a first damping rotating shaft 201, allowing the first C-shaped rotating base 2 to rotate at the front end of the fixed base 1. A rotating post 301 is fixedly connected to the rear end of the support arm 3. The rotating post 301 is inserted into the inside of the first C-shaped rotating base 2 and connected to the first C-shaped rotating base 2 through a second damping rotating shaft 302, allowing the rear end of the support arm 3 to rotate on the first C-shaped rotating base 2. A second C-shaped rotating shaft 302 is fixedly connected to the rear end of the battery box 4. The second C-shaped rotating seat 401 is inserted into the inner side of the second C-shaped rotating seat 401 and is rotatably connected to the second C-shaped rotating seat 401 through the third damping rotating shaft 402, so that the battery box 4 can rotate at the front end of the support arm 3. When the battery box 4 rotates, it drives the lamp holder 5 and LED tube 501 to rotate and adjust the direction. After the maintenance personnel enter the power well 6, they can pull the support arm 3 to rotate and adjust the position of the lamp holder 5 and LED tube 501. At the same time, the battery box 4 can be rotated to adjust the lighting direction of the LED tube 501.

[0026] Please see Figure 3 A battery 403 is fixedly installed inside the battery box 4. The battery 403 is electrically connected to the control switch 404. The LED tube 501 is electrically connected to the control switch 404. The control switch 404 controls the opening and closing of the LED tube 501.

[0027] Working Principle: During use, maintenance personnel enter the power well and manually adjust the angles of the support arm 3 and battery box 4 to achieve lighting positioning. The specific steps are as follows: First, hold the support arm 3 and apply external force, causing the first C-shaped rotating seat 2 to rotate horizontally via the first damping rotating shaft 201, so that the LED tube 501 faces the work area. Second, the support arm 3 can swing up and down around the second damping rotating shaft 302 to further adjust the lighting height. Finally, the battery box 4 is rotated via the third damping rotating shaft 402 to fine-tune the pitch angle of the LED tube 501, ensuring precise coverage of the maintenance points. By setting up a multi-degree-of-freedom adjustable lighting device, including the triple rotation structure of the first C-shaped rotating seat 2, support arm 3, and second C-shaped rotating seat 401, combined with the design of the first damping rotating shaft 201, second damping rotating shaft 302, and third damping rotating shaft 402, the LED tube 501 can achieve horizontal rotation, vertical swing, and pitch angle adjustment, accurately covering the maintenance needs of different locations within the power well and significantly improving lighting flexibility. After adjustment, press the control switch 404 on the battery box 4. The built-in battery 403 will power the LED tube 501, providing continuous and stable lighting. The design of the first damping rotating shaft 201, the second damping rotating shaft 302, and the third damping rotating shaft 402 ensures that each component remains fixed when there is no external force, preventing shaking. This device can adapt to different well depths and operational needs through multi-degree-of-freedom adjustment, eliminating the need for an external power supply or handheld lighting, significantly improving maintenance efficiency and safety.
