Description

Technical Field

[0001] This utility model belongs to the technical field of solar simulation devices, and in particular relates to an all-weather solar simulation device for research on healthy light environments. Background Technology

[0002] To meet the demand for precise solar simulation in healthy light environment research, natural sunlight is affected by weather, day and night, and seasons, and cannot provide continuous and stable experimental conditions. Therefore, all-weather solar simulation devices have become a core research tool.

[0003] Chinese patent application CN220119191U discloses a solar simulation device, including a support frame. Two first mounting brackets are positioned on either side of the top of the support frame, and a fixed platform is fixed between the two first mounting brackets. An adjusting plate is slidably connected to the front ends of the two first mounting brackets via slide rails. A second cylinder is fixed to the top of the fixed platform, and the piston rod of the second cylinder is connected to the adjusting plate. A lamp holder is fixed at the center of the front part of the adjusting plate, and an LED light panel is connected to the bottom of the lamp holder. A lifting platform for placing the photovoltaic panel is provided inside the support frame, and a scissor-type lifting assembly for adjusting the height of the lifting platform is provided at the bottom of the lifting platform. This structure enables adjustable illumination height.

[0004] This patent can only achieve adjustable illumination height, but it cannot simulate the rising and setting of the sun, nor can it simulate the sun's position in the four seasons. Therefore, it cannot guarantee the accuracy of the sunlight simulation function. To address this, we provide an all-weather sunlight simulation device for research on healthy light environments to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide an all-weather solar simulation device for research on healthy light environments. By combining the revolution component and the rotation component, it solves the problem that existing solar simulation devices cannot simulate the rising and setting of the sun and the changing position of the sun in the four seasons.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution.

[0007] This utility model relates to an all-weather sunlight simulation device for research on healthy light environments. It includes a revolution component, the output shaft of which is fixedly connected to a rotation component. The revolution component includes a first motor, the output shaft of which is fixedly connected to a track. A groove is formed at the top of the inner cavity of the track, and a rotating shaft is fixedly connected to the other end of the track. The rotation component includes a geared rail fixedly connected to the inner cavity of the track, with gears meshing at the top of the geared rail. A second motor is fixedly connected between the two gears, and a slider is fixedly connected to the top of the second motor. The slider slides within the groove, and a dual-output-shaft hydraulic telescopic rod is fixedly connected to the inner cavity of the slider. Locking plates are provided on the surface of the gears, and both ends of the dual-output-shaft hydraulic telescopic rod are fixedly connected to the locking plates.

[0008] The present invention is further configured such that the cross-sections of the track, the groove and the slider are all T-shaped. The T-shaped design can enhance the connection stability of the three, prevent the slider from detaching or shifting during the sliding process, and at the same time improve the load-bearing capacity of the overall structure, ensuring the stability of the rotating component when it moves on the track.

[0009] The present invention is further configured such that the revolution assembly includes friction plates disposed at the top and bottom of the output shaft of the first motor, the other end of the friction plate is fixedly connected to a hydraulic cylinder, and the other side of the hydraulic cylinder is fixedly connected to the surface of the first motor through a mounting base. The friction plate and the hydraulic cylinder cooperate to clamp the output shaft of the first motor by pushing the friction plate through the hydraulic cylinder after the first motor drives the track to complete the revolution positioning, thereby locking and fixing the revolution position, avoiding track position deviation due to external force or vibration, and improving the revolution positioning accuracy.

[0010] The present invention is further configured such that there are two toothed rails and gears, which are symmetrically distributed front and back. The two symmetrically distributed toothed rails and gears can make the second motor and the connected structure more evenly stressed, reduce the tilting or jamming phenomenon that may be caused by unilateral meshing, and improve the stability and smoothness of the rotation component movement.

[0011] The present invention is further configured such that the self-rotating component also includes a connecting rod fixedly connected to the bottom of the second motor, and a sunlight simulation lamp is fixedly connected to the bottom of the connecting rod, providing a stable mounting carrier for the simulation lamp.

[0012] The present invention is further configured such that the inner cavity of the slider is provided with a mounting hole, and the dual output shaft hydraulic telescopic rod is installed in the inner cavity of the mounting hole by bolts. The mounting hole and the bolts cooperate to make the installation and disassembly of the dual output shaft hydraulic telescopic rod more convenient.

[0013] The present invention is further configured such that a gap is left between the locking plate and the gear, which can prevent the locking plate from contacting the gear and causing friction and wear.

[0014] The present invention has the following beneficial effects.

[0015] 1. The orbital component of this utility model can drive the overall structure to achieve a trajectory similar to the Earth's revolution around the sun, while the rotation component can independently complete the simulation of the sun's position adjustment at different times of the day. This solves the problem that existing technologies can only adjust the height of illumination and cannot reproduce the dynamic trajectory of the sun. It provides more natural and realistic lighting conditions for the study of healthy light environment, ensures the accuracy and reliability of experimental data, and meets the research needs of all-weather and multi-scenario applications.

[0016] 2. The gear and toothed track meshing structure and the locking design of the dual output shaft hydraulic telescopic rod of this utility model realize the precise control and stable fixation of the rotation angle. Combined with the sliding cooperation of the track groove and slider of the revolution component, it ensures the smoothness and positioning accuracy of the movement process. It can provide continuous and accurate sunlight simulation for experiments over a long period of time, reduce experimental errors caused by equipment fluctuations, and provide more reliable hardware support for the research of healthy light environment.

[0024] The technical solutions of the present utility model will be described below with reference to the accompanying drawings. The described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0025] Please see Figure 1-5 This utility model is an all-weather sunlight simulation device for research on healthy light environment. It includes a revolution component 1, the output shaft of which is fixedly connected to a rotation component 2. The revolution component 1 includes a first motor 11, the output shaft of which is fixedly connected to a track 12. The top of the inner cavity of the track 12 is provided with a groove 13, and the other end of the track 12 is fixedly connected to a rotating shaft 14. The rotation component 2 includes a gear rail 21 fixedly connected to the inner cavity of the track 12. The top of the gear rail 21 is engaged with a gear 22. A second motor 23 is fixedly connected between the two gears 22. The top of the second motor 23 is fixedly connected to a slider 24. The slider 24 slides in the inner cavity of the groove 13. A dual-output shaft hydraulic telescopic rod 25 is fixedly connected to the inner cavity of the slider 24. A locking piece 26 is provided on the surface of the gear 22. Both ends of the dual-output shaft hydraulic telescopic rod 25 are fixedly connected to the locking piece 26.

[0026] Specifically: Through the coordinated action of the revolution component 1 and the rotation component 2, a multi-dimensional simulation of the sun's trajectory is achieved. The track 12 has an arc-shaped structure and is made of high-strength aluminum alloy. The top of the inner cavity of the track 12 has a groove 13 along its length. The inner wall of the groove 13 is smoothed to reduce sliding friction. The rotating shaft 14 is rotatably connected to the external fixed frame to provide stable support for the track 12. The tooth surface of the toothed rail 21 faces upward and is adapted to the curvature of the track 12. The tooth shape of the gear 22 matches the toothed rail 21 to ensure meshing stability. The outer wall of the slider 24 is tightly fitted to the inner wall of the groove 13 and can slide along the length of the groove 13. The outer surface of the locking piece 26 is provided with a wear-resistant layer and is in close contact with the inner wall of the track 12 to achieve the locking and fixing function.

[0027] The cross-sections of the track 12, the slide 13, and the slider 24 are all designed in a T-shape. The T-shape design can enhance the connection stability of the three and prevent the slider 24 from detaching or shifting during the sliding process. At the same time, it can improve the load-bearing capacity of the overall structure and ensure the smoothness of the rotation component 2 when it moves on the track 12.

[0028] The orbital assembly 1 also includes friction plates 15 disposed at the top and bottom of the output shaft of the first motor 11. The other end of the friction plate 15 is fixedly connected to a hydraulic cylinder 16. The other side of the hydraulic cylinder 16 is fixedly connected to the surface of the first motor 11 through a mounting base. The friction plate 15 and the hydraulic cylinder 16 cooperate to clamp the output shaft of the first motor 11 by pushing the friction plate 15 after the first motor 11 drives the track 12 to complete the orbital positioning, thereby locking and fixing the orbital position and preventing the track 12 from shifting due to external force or vibration, thus improving the orbital positioning accuracy.

[0029] There are two toothed rails 21 and gears 22, which are symmetrically distributed front and back. The two symmetrically distributed toothed rails 21 and gears 22 can make the second motor 23 and the connected structure more evenly stressed, reduce the tilting or jamming phenomenon that may be caused by unilateral meshing, and improve the stability and smoothness of the movement of the self-rotating component 2.

[0030] The self-rotating component 2 also includes a connecting rod 27 fixedly connected to the bottom of the second motor 23. A solar simulation lamp 28 is fixedly connected to the bottom of the connecting rod 27, and the connecting rod 27 provides a stable mounting carrier for the simulation lamp.

[0031] The inner cavity of the slider 24 has a mounting hole, and the dual output shaft hydraulic telescopic rod 25 is installed in the inner cavity of the mounting hole by bolts. The mounting hole and the bolts cooperate to make the installation and disassembly of the dual output shaft hydraulic telescopic rod 25 more convenient.

[0032] A gap is left between the locking plate 26 and the gear 22 to prevent the locking plate 26 from contacting the gear 22 and causing friction and wear.

[0033] The working principle of this utility model is as follows: During revolution, the first motor 11 drives the track 12 to rotate around the line connecting its output shaft and the rotating shaft 14. The track 12 drives the entire rotating component 2 to make an arc-shaped motion, simulating the seasonal position changes of the sun caused by the Earth's revolution. When it is necessary to simulate the day and night changes of the sun rising in the east and setting in the west, the second motor 23 drives the gear 22 to roll along the toothed track 21. The gear 22 drives the second motor 23 and the slider 24 to slide along the slide groove 13 of the track 12, thereby adjusting the angle of the rotating component 2. After adjusting to the target position, the double output shaft hydraulic telescopic rod 25 drives the locking plate 26 to tightly fit against the inner wall of the track 12, thereby fixing the rotation position. At the same time, the hydraulic cylinder 16 of the rotating component 1 can push the friction plate 15 to clamp the output shaft of the first motor 11, fixing the revolution position. The sunlight simulation lamp 28 moves with the rotating component 2, and its illumination direction is adjusted according to the position of the component, thereby achieving accurate simulation of sunlight in all weather conditions.

The preferred embodiments do not describe all the details in detail, nor do they limit the present utility model to the specific implementation methods described. The present specification selects and specifically describes these embodiments in order to better explain the principle and practical application of the present utility model, so that those skilled in the art can better understand and utilize the present utility model.
