Description

Technical Field

[0001] This utility model belongs to the field of equipment for tunnel construction, and specifically relates to a convenient energy-saving lighting device for tunnel construction. Background Technology

[0002] The construction environment of tunnels and underground engineering projects is complex and harsh, often lacking fixed power supply facilities, and the work face is constantly advancing. Therefore, extremely high requirements are placed on the portability, environmental adaptability, and energy efficiency of lighting devices. Currently, tunnel construction lighting mainly relies on the following methods: 1. Laying cables and fixed brackets directly along the tunnel wall, connecting the lights to the cables for illumination. However, this method has a long deployment time and cannot be moved quickly with the work face; 2. Using simple brackets to place portable LED lights. Although easy to move, these lights are unstable on uneven rocky ground, muddy ground, or steel supports, and are prone to tipping over due to equipment passage or personnel contact, posing a safety hazard. Furthermore, manual switching and brightness adjustment are usually required, and construction workers often leave them at maximum brightness for extended periods due to busyness or forgetfulness, especially in unattended or well-lit areas. This leads to rapid battery depletion, wasted energy, and frequent battery charging severely impacts construction efficiency. None of the above lighting methods meet the needs of efficient, safe, and energy-saving tunnel construction. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides a convenient energy-saving lighting device for tunnel construction. This solves the problem that manual switching and brightness adjustment are usually required, and construction workers often leave the device in the highest brightness mode for extended periods due to busyness or forgetfulness, especially in areas with ample light, which leads to rapid battery depletion and energy waste.

[0004] According to the embodiments of this utility model, the following technical solution is adopted:

[0005] A portable energy-saving lighting device for tunnel construction includes a base, a lighting lamp mounted on the base, a connecting component mounted on the base, and a detection and control component mounted on the base. The connecting component includes a magnetic suction component embedded in the base and / or a hanging component and / or a support component mounted on the base. The detection and control component includes a controller and a photosensitive sensor mounted on the base. The photosensitive sensor and the lighting lamp are both signal-connected to the controller. The controller is used to receive the light intensity signal from the photosensitive sensor and adjust the brightness of the lighting lamp according to the light intensity signal.

[0006] Compared with the prior art, the present invention has the following beneficial effects:

[0007] 1. The design of the magnetic components and / or hanging components and / or support components allows for multiple convenient installation methods for the base. Construction personnel can carry the base to the work site and choose how to install it according to the site construction environment. For example, the magnetic components can be directly attached to construction machinery and steel structures. On flat ground, the support components can be placed on the ground. Where anchor rods, steel mesh, etc. are erected, the hanging components can be suspended on them, making the use of this device more convenient.

[0008] 2. By setting up a photosensitive sensor, when the device is located in an area with sufficient natural light, such as a tunnel entrance, or when there are enough lighting devices in the environment to meet the light source requirements, the photosensitive sensor determines that the ambient light is bright enough, and the controller can adjust the brightness of the lights to avoid unnecessary energy consumption.

[0009] Furthermore, the magnetic attractor includes an electromagnet and / or a permanent magnet embedded in the base.

[0010] Furthermore, the hanging component includes a mounting ring fixed to the base and a safety hook detachably connected to the mounting ring.

[0011] Furthermore, the support includes a support rod mounted on the base and a support plate mounted on the end of the support rod, the support rod having at least three and more support rods arranged in a pyramidal shape.

[0012] Furthermore, the support rod is a telescopic rod.

[0013] Furthermore, the support rod includes a fixed part connected to the base and a movable part threadedly connected to the fixed part.

[0014] Furthermore, a connecting plate is detachably connected to the base, and the connecting plate and the hanging component are located on the same side of the base. The connecting plate has a through hole for the hanging component to pass through; the support rod is fixed to the connecting plate.

[0015] Furthermore, the detection and control component also includes a radar sensor that is signal-connected to the controller. The controller is used to receive the movement signal detected by the radar sensor and adjust the brightness of the lighting lamp according to the movement signal. Attached Figure Description

[0019] The present invention will be further described in detail below with reference to the accompanying drawings, and specific embodiments will be given.

[0020] like Figure 1 As shown, a portable energy-saving lighting device for tunnel construction includes a base 1, a lighting lamp 2 mounted on the base 1, a connecting component mounted on the base 1, and a detection and control component mounted on the base 1.

[0021] The connecting component is used to quickly install the device on various construction interfaces. The connecting component includes a magnetic suction component 3 embedded in the base 1 and / or a hanging component and / or a support component installed on the base 1. In order to improve the convenience and practicality of the device, in this embodiment, the magnetic suction component 3, the hanging component, and the support component are all integrated and installed on the base 1.

[0022] Specifically, the magnetic component 3 includes an electromagnet and / or a permanent magnet embedded in the base 1. The electromagnet can be a high-power DC electromagnet from existing technology, powered by an internal lithium battery. When energized, it generates a strong magnetic force, which can firmly adhere to any steel surface inside the tunnel, such as construction machinery or steel arches. When the power is off, the magnetic force disappears, and it can be easily removed. However, since electromagnets can be used in case of unexpected situations such as battery depletion, permanent magnets can also be used. However, permanent magnets are not easy to remove. In actual design, the choice between installing an electromagnet or a permanent magnet can be made depending on the situation, or both can be installed. This allows the permanent magnet to serve as an auxiliary or backup, ensuring that it still has a certain attraction capacity in case of unexpected situations such as battery depletion of the electromagnet.

[0023] The suspension system includes a mounting ring 4 fixed to the base 1 by welding or bolting, and a safety hook 5 detachably connected to the mounting ring 4. The safety hook 5 is a standard engineering anti-detachment safety hook 5 from the prior art, which can be easily hung on anchor bolts, steel mesh, or pre-set suspension points at the top of the tunnel to achieve suspended lighting. The suspension system and the lighting lamp 2 are located on both sides of the base 1. In actual design, to facilitate adjustment of the suspension height, ropes can be tied to the mounting ring 4, and then the safety hook 5 can be connected to the ropes. That is, by setting ropes of different lengths between the mounting ring 4 and the safety hook 5, the suspension height of the lighting lamp 2 can be adjusted.

[0024] Combination Figure 2As shown, the support includes a support rod 8 mounted on the base 1 and a support plate 9 mounted on the end of the support rod 8. The support rod 8 has at least three or more support rods arranged in a pyramidal shape. Specifically, the support rod 8 can be directly fixed to the base 1, and the support plate 9 can also be directly fixed to the support rod 8. In actual design, other installation methods (such as hinges) can also be used to ensure that the support rod 8 can stand upright on the ground to support the base 1. In actual design, an anti-slip plate 10 is also fixed to the end of the support plate 9. The anti-slip plate 10 is made of wear-resistant rubber, and textures to increase friction can be set on the surface of the anti-slip plate 10 to effectively prevent slippage on smooth or sloping surfaces.

[0025] The detection and control components include a controller and a photosensitive sensor mounted on the base 1. The controller is a microcontroller or other controller with programmable control functions, as is currently available in the technology. Both the photosensitive sensor and the lighting lamp 2 are connected to the controller via signal transmission. The controller receives the light intensity signal from the photosensitive sensor and adjusts the brightness of the lighting lamp 2 accordingly. For example, when the ambient light intensity is higher than a set threshold (e.g., near a tunnel entrance during the day), the controller controls the lighting lamp 2 to reduce its output power or turn it off; when the ambient light intensity is lower than the set threshold, the controller controls the lighting lamp 2 to turn on or increase its brightness.

[0026] In another embodiment of this utility model, the support rod 8 is a telescopic rod. The support rod 8 includes a fixed part 6 connected to the base 1 and a movable part 7 threadedly connected to the fixed part 6. By rotating the movable part 7, the length of the support rod 8 can be adjusted. This design allows the user to independently adjust the length of each support rod 8 according to the flatness of the ground and the required lighting height, ensuring that the lighting lamp 2 can be placed stably.

[0027] In another embodiment of this utility model, a connecting plate 11 is detachably connected to the base 1, and a support rod 8 is fixed on the connecting plate 11. The connecting plate 11 and the hanging component are located on the same side of the base 1, and a through hole 12 is provided on the connecting plate 11 for the mounting ring 4 of the hanging component to pass through. This design allows the support component to be quickly installed or disassembled as a whole module, facilitating transportation, storage, and subsequent maintenance and replacement.

[0028] In another embodiment of this utility model, the detection and control component further includes a radar sensor connected to the controller. The controller receives the movement signal detected by the radar sensor and adjusts the brightness of the lighting lamp 2 according to the movement signal. Specifically, the radar sensor can be a microwave radar module from the prior art, with its detection direction facing the illuminated area, capable of detecting the movement signals of people or vehicles. The control logic is as follows: when no movement signal is detected within a set time, the controller controls the lighting lamp 2 to switch to a low-power "standby mode"; once a movement signal is detected, the controller immediately controls the lighting lamp 2 to return to the full-power "working mode," achieving an intelligent energy-saving effect of "lights on when people are present, lights off when people leave." In actual design, sound control or infrared sensors can also be used to detect whether people or vehicles are passing through the tunnel.
