Description

Technical Field

[0001] The utility model belongs to the technical field of meteorological simulation equipment, in particular to a device for simulating the intensity of sunlight and the daily changing position of the sun in a certain place indoors. Background Art

[0002] Simulating natural indoor lighting environments, particularly the diurnal variations in sunlight intensity and position at specific locations, has long been a research hotspot in the fields of optics and environmental simulation. With increasing attention to the quality of living and working environments, the demand for precise light environment control in specific application scenarios (such as agricultural planting and biological experiments), and the need for local solar radiation simulation for meteorological science, the importance of such technologies is self-evident. Consequently, several devices designed to simulate the trajectory of solar radiation have emerged on the market.

[0003] For example, patent application number CN202310579814.4 discloses an experimental device that simulates a bridge under the combined effects of wind and sunlight. The device "comprises a bridge model, a wind simulation unit, a sunlight simulation unit, and a ground reflection structure. The present invention simulates the effect of the solar temperature field on the bridge by providing a sunlight simulation unit and a ground reflection structure, providing designers with data on the impact of temperature on the bridge, which helps to analyze and solve the current temperature problems in bridge construction. The blower installed on the side adjusts the wind speed in different gears and the wind direction angle at the same time, thereby simulating the static and dynamic effects of wind on the bridge in a natural environment, and reflecting the changes in the wind pressure value of the bridge. The effects of wind acting at different positions on the bridge provide designers with valuable experimental data when designing bridges, reducing project costs. The device has a simple structure, low manufacturing cost, and good applicability." Although the above structure can achieve changes in the trajectory of sunlight, because the arc frame can only move in a circle along the circular frame, it cannot simulate changes in the angle of sunlight in the four seasons, nor can it simulate the adjustment of the distance of light from the ground.

[0004] In order to solve the above problems, we provide a device that can simulate the sunlight intensity and diurnal changing position of a certain place indoors, which can simulate the sunlight angle, brightness and trajectory of the sun in different geographical locations in four seasons indoors.

[0005] The utility model aims to overcome the deficiencies in the prior art and provide a device for simulating the intensity of sunlight and the changing position of the sun in a certain place indoors.

[0006] The purpose of the utility model is achieved as follows: a device for simulating the intensity of sunlight and the changing position of the sun in a certain place indoors, comprising two symmetrically distributed support frames, wherein the upper ends of the two support frames are rotatably provided with an arc frame, and an irradiation lamp is provided on the arc frame. The irradiation lamp can move along the arc frame, and the irradiation lamp irradiates inward along the arc frame.

[0007] Furthermore, a rotating seat is fixedly provided at both ends of the arc-shaped frame, and the two rotating seats are rotatably connected to the upper parts of the support frames on both sides.

[0010] Furthermore, an arc-shaped slide groove is opened in the middle of the outer side surface of the arc frame, and a traction rope is arranged in the arc-shaped slide groove. The middle part of the traction rope is fixedly connected to the telescopic electric cylinder. The traction rope moves back and forth along the arc-shaped slide groove, and the traction rope drives the telescopic electric cylinder to move along the arc frame.

[0011] When the present invention is used, the electrical components are controlled by a controller. The controller is prior art and will not be described in detail. It is sufficient to achieve the following functions of the present invention: the controller controls the coordinated rotation of two rotating motors, one of which drives the traction rope, while the other drives the traction rope, thereby enabling the traction rope to drive the lamp to move along the arc frame, thereby achieving the change of the sun's position throughout the day. The controller controls the telescopic electric cylinder to move the lamp up and down, and the distance between the lamp and the ground can be adjusted as needed.

[0012] The controller controls the rotating motor to rotate, and when the rotating motor rotates, it drives the rotating seat to rotate, and when the rotating seat rotates, it drives the arc frame to rotate, thereby changing the arc trajectory of the irradiation lamp when it moves, which is used to simulate the changes in the solar orbit in different seasons. This application only simulates the changes in the sun's position during the seasons and during the day, and cannot accurately reproduce the sun's trajectory and illumination brightness angle, etc. It is only for popular science or reference. As for the problem of moving the traction rope back and forth and storing it, it is sufficient to realize the forward and backward movement of the traction rope and always keep the traction rope taut. There is no technical limitation on other technical details, and it is sufficient to realize the above functions.

[0013] Beneficial effects: This application can simulate the changes in the trajectory of the sun in different regions during the day in different seasons indoors. At the same time, a lamp that can be adjusted up and down is provided to replace sunlight, and the distance between the light and the ground can be adjusted. Through the above technical solution, the changes in the trajectory of the sun's position can be simulated uninterruptedly during the day, and a lamp with adjustable brightness can simulate sunlight of different brightness.

[0020] Example 1, as Figure 1 —4, the purpose of the utility model is achieved as follows: a device for simulating the intensity of sunlight and the changing position of the sun in a certain place indoors, comprising two symmetrically distributed support frames 1, wherein the upper ends of the two support frames 1 are rotatably provided with an arc frame 5, and the arc frame 5 is provided with an irradiation lamp 4, which can move along the arc frame 5, and the irradiation lamp 4 irradiates inward along the arc frame 5.

[0021] A rotating base 7 is fixedly mounted at each end of the curved frame 5. These two rotating bases 7 are rotatably connected to the upper portion of the support frame 1 on either side. A rotating motor 3 is mounted on the inner side of the upper portion of the support frame 1. The output end of the rotating motor 3 is fixedly connected to the rotating base 7, driving the rotating base 7 to rotate. A telescopic electric cylinder 6 is installed between the illumination lamp 4 and the curved frame 5. The output end of the telescopic electric cylinder 6 is fixedly connected to the illumination lamp 4, and the telescopic electric cylinder 6 moves along the curved frame 5.

[0022] A curved chute is defined in the middle of the outer side of the curved frame 5. A traction rope 8 is positioned within the chute, which is fixedly connected to the telescopic cylinder 6 at its center. The traction rope 8 moves forward and backward along the curved chute, driving the telescopic cylinder 6 along the curved frame 5. Each rotating base 7 has a receiving slot 10 defined within it. A rotating shaft 9 is rotatably positioned in the middle of each slot, with each end of the traction rope 8 fixedly wound around the shaft 9. A drive motor 2 is fixedly positioned on the outer side of the rotating base 7. The output end of the drive motor 2 is fixedly connected to the shaft 9, driving the shaft 9 in rotation. The brightness of the illumination lamp 4 is adjustable.

[0023] When the present invention is in use, the electrical components are controlled by a controller. The controller is prior art and will not be described in detail. It is sufficient to achieve the following functions of the present invention: The controller controls the coordinated rotation of two rotating motors 3, with one driving motor 2 rotating to receive the traction rope 8 and the other driving motor 2 rotating to release the traction rope 8. This traction rope 8 then drives the illumination lamp 4 along the curved frame 5, thereby achieving changes in the sun's position throughout the day. The controller controls the telescopic electric cylinder 6 to move the illumination lamp 4 up and down, allowing the distance between the illumination lamp 4 and the ground to be adjusted as needed.

[0024] The controller controls the rotating motor 3 to rotate, which drives the rotating base 7 to rotate. When the rotating base 7 rotates, it drives the arc frame 5 to rotate, thereby changing the arc trajectory of the irradiation lamp 4 during movement, which is used to simulate the changes in the solar orbit in different seasons. This application only simulates the changes in the sun's position during the seasons and during the day, and cannot completely accurately reproduce the sun's trajectory. It is only for popular science or reference. Regarding the problem of moving the traction rope 8 back and forth and storing it, it is sufficient to achieve the forward and backward movement of the traction rope 8 and always keep the traction rope 8 taut. There are no technical restrictions on other technical details. It is sufficient to achieve the above functions.
