Description

Technical Field

[0001] This utility model relates to the field of lighting technology, specifically a sunlight-guiding lighting device for confined space operations. Background Technology

[0002] In fields such as industrial production, municipal maintenance, and mining, confined space operations, such as underground pipeline repair, mine tunnel operations, enclosed plant construction, and internal maintenance of storage tanks, are common work scenarios. These scenarios are generally characterized by enclosed or semi-enclosed spaces where natural light cannot directly penetrate. Sufficient and stable lighting is a core prerequisite for ensuring the safe operation of workers, improving work efficiency, and avoiding safety accidents such as collisions, misoperations, and misjudgments of toxic and harmful gases.

[0003] Existing confined space lighting mostly uses mains power or battery power. If mains power is used, temporary cables need to be laid, which is not only limited by the space of the work site, such as narrow passages and complex pipelines, but also prone to wear and tear and leakage risks due to cable dragging. Moreover, it cannot meet the needs of mobile operations. If battery power is used, the battery capacity is limited, and the battery life is generally short, usually only 4-8 hours. Frequent shutdowns for replacement or charging are required, which seriously interrupts the work process and is especially unsuitable for long-term continuous operation scenarios. Some existing technologies attempt to introduce sunlight into confined spaces to replace traditional lighting, but such devices generally lack dynamic adjustment capabilities and only use fixed-angle lighting structures. They cannot adjust the lighting angle and direction according to the sun's position, such as its movement during the day and night and seasonal changes. As a result, sunlight can be effectively collected only for a few periods of the day, and auxiliary lighting is required for the rest of the time, resulting in insufficient utilization of sunlight. Summary of the Invention

[0004] The purpose of this invention is to solve the problems existing in the prior art and to provide a sunlight-guiding lighting device for confined space operations.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A confined space operation sunlight-guiding lighting device, comprising: The device body has a steering adjustment mechanism and an angle adjustment mechanism on its top. The angle adjustment mechanism has a high-efficiency light-collecting mirror on its top and a light sensor on one side of its side.

[0006] The lighting device housing is located on one side of the vehicle body. A light sensor is installed on the lighting device housing. A lighting mechanism is installed inside the lighting device housing. A removable part is provided on the top of the lighting device housing. A high-reflectivity light guide tube is provided between the lighting device housing and the steering adjustment mechanism. A solar panel is installed on one side of the top of the vehicle body.

[0007] In a preferred embodiment of the present invention, the steering adjustment mechanism includes a drive unit 1 installed on the top of the device body, and a steering wheel is tractively connected to the top of the drive unit 1.

[0008] In a preferred embodiment of the present invention, the angle adjustment mechanism includes a support frame fixed to the center of the top of the steering wheel, a second drive unit is installed on one side wall of the support frame, the high-efficiency light-collecting mirror is rotatably connected to one side of the inner wall of the support frame, and the output shaft of the second drive unit rotatably passes through the surface of the support frame and is connected to the high-efficiency light-collecting mirror via transmission.

[0009] In a preferred embodiment of this utility model, a pusher is fixedly connected to the top edge of the device body, the optical sensor is mounted on the pusher, and pulleys are installed at the four corners of the bottom of the device body.

[0010] In a preferred embodiment of this utility model, a protective cover is fixedly connected to the top of the steering adjustment mechanism, and both the angle adjustment mechanism and the high-efficiency light-collecting mirror are placed inside the protective cover, which is made of a light-transmitting material.

[0011] In a preferred embodiment of the present invention, the lighting mechanism includes a drive unit three installed on the inner wall of the lighting device housing, and a lighting lamp is drivenly connected to the output shaft of the drive unit three. The lighting lamp is electrically connected to a light sensor.

[0012] In a preferred embodiment of this utility model, the easy-to-disassemble component includes a threaded cylinder that is fixedly inserted through the top of the housing of the lighting device. A threaded sleeve is fitted on the high reflectivity light guide tube, and the threaded sleeve is threadedly connected to the threaded cylinder. One end of the high reflectivity light guide tube is connected to the lighting lamp through the threaded cylinder, and the other end of the high reflectivity light guide tube is inserted through the steering wheel and connected to the high-efficiency light-collecting mirror.

[0013] In a preferred embodiment of the present invention, the optical sensor is electrically connected to the first driving unit and the second driving unit.

[0014] Compared with the prior art, the present invention has the following beneficial effects: The confined space operation sunlight-guiding lighting device provided by this utility model effectively avoids the shortcomings of traditional mains power and battery power supply through the dual energy design of sunlight guidance and solar energy storage. On the one hand, the solar panel on the top of the device can collect and store solar energy in real time, providing auxiliary power for the entire device such as steering adjustment mechanism, angle adjustment mechanism and lighting mechanism, reducing dependence on mains power. On the other hand, the high reflectivity light guide tube directly guides the sunlight collected by the high efficiency light-collecting lens into the confined space, replacing part of the energy consumption of artificial lighting. The two work together to avoid the space limitations of laying temporary cables for mains power supply, such as narrow passages, complex pipeline obstruction and leakage risk, and eliminates the need for frequent shutdowns for replacement or charging, significantly extending the continuous operation time, especially suitable for long-term confined space operation scenarios.

[0015] This utility model provides a confined space operation sunlight guiding lighting device, which addresses the problems of fixed structure and low utilization rate of existing sunlight guiding devices. It achieves precise dynamic lighting through a light sensor and dual adjustment mechanism. The light sensor detects changes in the sun's position in real time, such as day-night movement and seasonal changes, and transmits the signals to the drive unit one of the steering adjustment mechanism and the drive unit two of the angle adjustment mechanism. The drive unit one drives the steering wheel to rotate, realizing the horizontal steering adjustment of the high-efficiency light-collecting mirror. The drive unit two drives the high-efficiency light-collecting mirror to rotate around the support frame, completing the vertical angle adjustment. This design allows the high-efficiency light-collecting mirror to always be aligned with the sun, avoiding the problem of effective lighting only during a few periods of time, greatly improving the utilization rate of sunlight, reducing dependence on auxiliary lighting, and reducing energy consumption.

[0016] The confined space operation sunlight guiding lighting device provided by this utility model uses a threaded sleeve and a threaded cylinder for easy disassembly, which can quickly disassemble or assemble the high reflectivity light guide tube and lighting mechanism without special tools. This not only facilitates the storage and protection of components when the work site is moved, but also allows for flexible adjustment of the light guiding path according to the height and width requirements of the confined space. At the same time, the high reflectivity light guide tube can minimize the loss of sunlight during transmission, ensure the light intensity entering the confined space, and further improve the lighting effect.

[0017] The confined space operation sunlight-guiding lighting device provided by this utility model achieves intelligent light adaptation through a light sensor and lighting mechanism. The light sensor detects the light intensity in the confined space in real time. If the sunlight guided by the high-reflectivity light guide tube is too strong or too weak, it triggers the drive unit of the lighting mechanism to adjust the brightness or angle of the lighting lamp. When it is too strong, the lighting lamp power is reduced, and when it is too weak, the power is increased, ensuring that the lighting in the confined space is always maintained within a stable and comfortable range, avoiding misoperation or visual fatigue caused by lighting problems, and ensuring work safety and efficiency.

[0021] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention 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 invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.

[0022] like Figures 1 to 5As shown, this embodiment provides a confined space operation sunlight guiding lighting device, including a device body 1. A steering adjustment mechanism 2 and an angle adjustment mechanism 3 are installed on the top of the device body 1. A high-efficiency light-collecting mirror 4 is installed on the top of the angle adjustment mechanism 3, serving as the core front-end for sunlight collection. Its high-efficiency light-collecting characteristics can increase the amount of light collected per unit area, providing a sufficient light source for the high-reflectivity light guide tube 10 to transmit light, reducing reliance on auxiliary lighting. A light sensor 5 is installed on one side of the steering adjustment mechanism 2 to detect changes in the sun's azimuth in real time. The light sensor 5 and the drive unit 2... 1 and drive unit 2 are electrically connected. A push frame 11 is fixedly connected to the top edge of the device body 1 for the operator to push the device to move. The light sensor 5 is installed on the push frame 11. Pulleys 12 are installed at the four corners of the bottom of the device body 1 to provide the device with mobility and reduce ground friction resistance. A protective cover 13 is fixedly connected to the top of the steering adjustment mechanism 2 to protect the core lighting components from dust and debris in the confined space and from collision damage during operation. The angle adjustment mechanism 3 and the high-efficiency lighting mirror 4 are both placed in the inner cavity of the protective cover 13. The protective cover 13 is made of light-transmitting material.

[0023] The lighting device housing 6 is located on one side of the device vehicle body 1. A light sensor 7 is installed on the lighting device housing 6 to provide a light adjustment signal to the lighting mechanism 8. The lighting mechanism 8 is installed inside the lighting device housing 6. A removable part 9 is installed on the top of the lighting device housing 6. A high reflectivity light guide tube 10 is installed between the lighting device housing 6 and the steering adjustment mechanism 2 to transmit the sunlight collected by the light-collecting mirror into the confined space. A solar panel 14 is installed on one side of the top of the device vehicle body 1.

[0024] The steering adjustment mechanism 2 includes a drive unit 21 installed on the top of the device body 1, specifically a motor. The top of the drive unit 21 is connected to a steering wheel 22. After receiving the signal from the light sensor 5, the drive unit 21 drives the steering wheel 22 to rotate horizontally, thereby driving the angle adjustment mechanism 3 and the high-efficiency light-collecting mirror 4 above to achieve horizontal steering.

[0025] The angle adjustment mechanism 3 includes a support frame 31 fixed at the top center of the steering wheel 22. A drive unit 32, specifically a motor, is installed on one side wall of the support frame 31. The high-efficiency light-collecting mirror 4 is rotatably connected to one side of the inner wall of the support frame 31. The output shaft of the drive unit 32 rotates through the surface of the support frame 31 and is connected to the high-efficiency light-collecting mirror 4 for transmission, thereby realizing the vertical angle adjustment of the high-efficiency light-collecting mirror 4. This adapts to seasonal changes in solar altitude, such as high solar altitude in summer and low solar altitude in winter, avoiding the problem of only effective light collection during a few periods of time and greatly improving the utilization rate of sunlight.

[0026] The lighting mechanism 8 includes a drive unit 81 installed on the inner wall of the lighting device housing 6, specifically a motor. A lighting lamp 82 is driven and connected to the output shaft of the drive unit 81. The lighting lamp 82 is electrically connected to the light sensor 7. After receiving the signal from the light sensor 7, the drive unit 81 adjusts the brightness or angle of the lighting lamp 82.

[0027] The easy-to-disassemble component 9 includes a threaded cylinder 91 that is fixedly inserted through the top of the lighting device housing 6. A threaded sleeve 92 is fitted on the high reflectivity light guide tube 10. The threaded sleeve 92 is threadedly connected to the threaded cylinder 91. One end of the high reflectivity light guide tube 10 is connected to the lighting lamp 82 through the threaded cylinder 91. The other end of the high reflectivity light guide tube 10 passes through the steering wheel 22 and is connected to the high efficiency light-collecting mirror 4. This component is used to enable quick disassembly and assembly of the high reflectivity light guide tube 10 and the lighting device housing 6.

[0028] The usage process of the confined space operation sunlight-guiding lighting device described in this embodiment is as follows: The vehicle body 1 serves as the overall load-bearing foundation. A solar panel 14 on one side of its top collects and stores solar energy in real time, providing auxiliary power to the steering adjustment mechanism 2, angle adjustment mechanism 3, and lighting mechanism 8. Simultaneously, a light sensor 5 mounted on the pusher 11 at the top edge of the vehicle body 1 detects changes in the sun's position in real time, such as day-night shifts and seasonal changes, and transmits electrical signals to the drive unit 21 of the steering adjustment mechanism 2 and the drive unit 32 of the angle adjustment mechanism 3. The drive unit 21 drives the steering wheel 22, which is connected to the top of the steering wheel, to rotate horizontally, thereby causing the angle adjustment mechanism 3, fixed to the top of the steering wheel 22, to turn horizontally. In the angle adjustment mechanism 3, the drive unit 32, fixed to the side wall of the support frame 31 at the center of the top of the steering wheel 22, has its output shaft passing through the support frame 31 and driving the high-efficiency light-collecting mirror 4, which is rotatably connected to the inner wall of the support frame 31, to rotate vertically. This ensures that the high-efficiency light-collecting mirror 4 is always precisely aligned with the sun for efficient sunlight collection, and the steering... The light-transmitting protective cover 13 at the top of the adjustment mechanism 2 encloses and protects the angle adjustment mechanism 3 and the high-efficiency light-collecting mirror 4, preventing damage from dust and collisions without affecting light transmission. The sunlight collected by the high-efficiency light-collecting mirror 4 passes through the steering wheel 22 at one end and is connected to the high-reflectivity light guide tube 10 of the lighting lamp 82 inside the lighting device housing 6 through the easy-to-disassemble part 9 at the other end, minimizing light loss and transmitting sunlight to the confined space. At the same time, the light sensor 7 installed on the lighting device housing 6 detects the light intensity in the confined space in real time. If the sunlight is too strong or too weak, it transmits the signal to the drive unit 81 of the lighting mechanism 8. The drive unit 81 drives the lighting lamp 82 connected to its output shaft to adjust the brightness or angle. When it is too strong, the power is reduced; when it is too weak, the power is increased, ensuring stable and comfortable lighting in the confined space. The pulleys 12 at the four corners of the bottom of the device body 1 facilitate the flexible movement of the entire device in the confined space, adapting to the needs of different working positions.

The accompanying drawings show preferred embodiments of this utility model, but do not limit the patent scope of this utility model. This utility model can be implemented in many different forms; rather, the purpose of providing these embodiments is to provide a more thorough and comprehensive understanding of the disclosure of this utility model.
