Description

Technical Field

[0001] This utility model relates to the field of indoor lighting technology, and in particular to a large lens-type sunlight guiding device. Background Technology

[0002] With the continuous development of green building and energy-saving technologies, natural light utilization systems are playing an increasingly important role in the modern lighting field. As an intelligent device that efficiently collects and transmits outdoor sunlight to indoor lighting, sunlight guide devices are widely used in underground spaces, windowless areas, office buildings, shopping malls and residences, which can significantly reduce artificial lighting energy consumption and improve the quality of indoor light environment.

[0003] However, existing sunlight-guiding devices still have many shortcomings in practical applications. Traditional structures mostly use fixed or manually adjustable concentrating components, which cannot follow the changes in the sun's position in real time, resulting in a significant decrease in light-gathering efficiency over time.

[0004] Therefore, it is necessary to design a large-lens sunlight import device. Utility Model Content

[0005] In order to overcome the shortcomings of existing sunlight-guiding devices that cannot follow the changes in the sun's position in real time, resulting in a decrease in light-gathering efficiency, the technical problem is to provide a large-lens type sunlight-guiding device.

[0006] The technical solution is as follows: A large lens-type sunlight guiding device includes a mounting plate, a connecting plate, a support plate, a support frame, a sunlight sensor, a motor, a Fresnel lens, a connecting block, a fixing plate, a controller, and a sunlight guiding fiber. The mounting plate has several mounting holes on its lower periphery. Multiple connecting plates are fixedly mounted in a circular array on the upper periphery of the mounting plate. Each connecting plate is fixedly connected to a support plate at its upper end. Support frames are fixedly connected to both sides of the upper surface of the support plate. A support frame is rotatably mounted between the upper parts of the two support frames via a rotating shaft. The upper right side of the support frame... A sunlight sensor is fixedly mounted to monitor the direction of sunlight in real time. A controller is fixedly mounted on the front side wall of the middle of the mounting plate. The sunlight sensor is electrically connected to the controller. A motor is fixedly mounted on the upper part of the support frame on the right side of the support plate. The controller is electrically connected to the motor. The output shaft of the motor is fixedly connected to the rotating shaft of the support frame. The support frame is a hollow structure. A Fresnel lens is fixedly mounted on the middle of the upper end face of the support frame. Fixed plates are fixedly connected to the lower ends of the four sides of the support frame through connecting blocks. A certain number of light-collecting slots are fixedly opened on the fixed plates. Each light-collecting slot is fixedly equipped with a sunlight-guiding optical fiber.

[0007] Furthermore, the Fresnel lens surface is coated with an anti-reflective coating.

[0008] Furthermore, the sunlight-guiding fiber is a graded-index multimode fiber, which can reduce light scattering loss during transmission.

[0009] Furthermore, it also includes a rain cover and a convex plate. The rain cover is fixedly installed on the periphery of the upper surface of the support plate, and the convex plate is fixedly connected to the lower end of the rain cover. The rain cover is fixedly connected to the support plate through the convex plate.

[0010] Furthermore, the rain cover is made of transparent material.

[0011] Furthermore, it also includes temperature optical fibers, temperature sensors, and straps. Temperature optical fibers are arranged around the lower part of multiple sunlight-guiding optical fibers. Straps are provided at the part of the temperature optical fibers that contact the sunlight-guiding optical fibers. Temperature sensors are fixed to the ends of the temperature optical fibers. Temperature sensors are electrically connected to the controller.

[0012] The beneficial effects are as follows: 1. By setting up an automatic tracking control system consisting of a sunlight sensor, a controller and a motor, and cooperating with the rotation structure of the support frame and the rotating shaft, the Fresnel lens can automatically adjust its angle under the drive of the motor, so as to achieve continuous tracking of the sun's position, thereby significantly improving the continuity and stability of sunlight collection and maximizing the utilization of solar energy resources.

[0013] 2. This utility model provides a transparent rain cover on the support frame and securely connects it to the support plate via a convex plate. The rain cover effectively blocks rain, snow, and dust, preventing them from adhering to the Fresnel lens surface and affecting the light-gathering efficiency. At the same time, it protects moving parts such as motors and shafts from moisture corrosion, thereby extending the service life of the equipment under complex outdoor weather conditions.

The lower periphery of the mounting plate 1 has several mounting holes 11. The upper periphery of the mounting plate 1 has multiple connecting plates 12 arranged in a ring array and screwed onto it. Each connecting plate 12 is connected to a support plate 13 via screws at its upper end. Support frames 2 are fixed to the left and right sides of the upper surface of the support plate 13. A support frame 21 is rotatably mounted between the upper parts of the two support frames 2 via a rotating shaft. A sunlight sensor 22 is fixed to the right side of the upper surface of the support frame 21 for real-time monitoring of the direction of sunlight incidence. The middle of the mounting plate 1... A controller 27 is installed on the front side wall by screws. A sunlight sensor 22 is electrically connected to the controller 27. A motor 23 is installed on the upper part of the support frame 2 on the right side of the support plate 13 by screws. The controller 27 is electrically connected to the motor 23. The output shaft of the motor 23 is fixedly connected to the rotating shaft of the support frame 21. The support frame 21 is a hollow structure. A Fresnel lens 24 is fixedly installed in the middle of the upper surface of the support frame 21. A fixing plate 26 is fixedly connected to the lower end of the four sides of the support frame 21 by connecting blocks 25. A certain number of light collecting slots 3 are fixedly opened on the fixing plate 26. A sunlight guiding fiber 31 is fixedly installed in each of the light collecting slots 3. The surface of the Fresnel lens 24 is coated with an anti-reflection and anti-reflection film. The sunlight guiding fiber 31 is a graded refractive index multimode fiber, which can reduce light scattering loss during transmission.

[0024] like Figure 1 , Figure 2 and Figure 4 As shown, it also includes a rain cover 14 and a convex plate 15. The rain cover 14 is fixedly installed on the periphery of the upper surface of the support plate 13, and the convex plate 15 is fixedly connected to the lower end of the rain cover 14. The rain cover 14 is fixedly connected to the support plate 13 through the convex plate 15. The rain cover 14 is made of transparent material.

[0025] like Figure 6 , Figure 7 and Figure 8 As shown, it also includes a temperature fiber 4, a temperature sensor 41, and a strap 42. The temperature fiber 4 is arranged around the lower part of multiple sunlight-guiding fibers 31. The part of the temperature fiber 4 that contacts the sunlight-guiding fiber 31 is provided with a strap 42. The temperature sensor 41 is fixed to the end of the temperature fiber 4. The temperature sensor 41 is electrically connected to the controller 27.

[0026] When using the large lens-type sunlight guide device, the entire device is first fixed to a lighting location such as a roof or exterior wall through the mounting holes 11 on the lower periphery of the mounting plate 1. A support frame 21 is rotatably mounted between the support frames 2 on the left and right sides of the upper end face of the support plate 13 via a rotating shaft. A large-area Fresnel lens 24 is fixedly mounted in the middle of the upper end face of the support frame 21. Its surface is coated with an anti-reflection and anti-reflection film, which can effectively reduce light reflection loss and improve light transmittance. A sunlight sensor 22 is fixedly connected to the right side of the upper end face of the support frame 21 to monitor the incident direction and light intensity of sunlight in real time and transmit the signal to the controller 27 on the front side wall of the mounting plate 1. The controller 27 controls the motor 23 on the upper part of the support frame 2 on the right side of the support plate 13 to start according to the feedback signal of the sunlight sensor 22. The output shaft of the motor 23 drives the rotating shaft of the support frame 21 to rotate, thereby driving the entire support frame 21 and the Fresnel lens 24 on it to automatically adjust the angle with the light collecting groove 3 on the fixed plate 26 to achieve sunlight... Real-time tracking of the sun's position ensures that sunlight always enters at the optimal angle. After being efficiently focused by the Fresnel lens 24, the sunlight is conducted into the light-collecting slot 3 through the hollow structure of the support frame 21. A graded refractive index multimode sunlight-guiding fiber 31 is fixedly installed in the light-collecting slot 3. The focused sunlight is coupled into each sunlight-guiding fiber 31 and delivered to the indoor lighting area. To prevent rain and dust from contaminating the optical components, a transparent rainproof cover 14 is provided on the periphery of the upper surface of the support plate 13. Its lower end is fixedly connected to the support plate 13 through a protruding plate 15, which can shield against severe weather without affecting the light. At the same time, temperature-sensitive fiber 4 is arranged around the lower part of multiple sunlight-guiding fibers 31. The contact part of the two is bound together with a strap 42. The temperature sensor 41 at the end of the temperature-sensitive fiber 4 monitors the fiber temperature in real time and feeds the data back to the controller 27. When the temperature exceeds the safety threshold, the controller 27 can automatically adjust the tracking angle or stop operation to achieve overheat protection and ensure the long-term stable operation of the system.
