Description

Technical Field

[0001] This utility model relates to the field of solar radiation measurement equipment technology, and in particular to a solar direct radiation testing mechanism. Background Technology

[0002] Photocatalysis, as a green and environmentally friendly energy conversion and pollution control technology, has received widespread attention in recent years in fields such as water treatment, air purification, and environmental remediation. The efficiency of photocatalytic reactions is directly affected by the intensity of solar radiation and the quality of the light source, especially the ratio of direct solar radiation to diffused radiation. Therefore, accurately measuring solar radiation intensity, particularly direct and diffuse solar radiation, is crucial for optimizing the photocatalytic reaction process.

[0003] While existing solar radiation measurement equipment can measure total radiation, it typically cannot simultaneously and accurately measure both direct and diffuse solar radiation, and suffers from drawbacks such as slow response, complex installation, and large equipment size.

[0004] Therefore, there is an urgent need for a solar direct radiation testing mechanism that is simple in structure, small in size, and capable of simultaneously measuring the intensity of direct and diffuse solar radiation reaching the ground. Utility Model Content

[0005] The purpose of this invention is to provide a solar direct radiation testing mechanism that solves the problems of complex structure and inability to simultaneously and accurately measure both direct and diffuse solar radiation in existing technologies. The various technical effects of the preferred solutions among the many technical solutions provided by this invention are detailed below.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0031] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0032] refer to Figure 1-2 A specific embodiment of this utility model provides a solar direct radiation testing mechanism, comprising:

[0033] Electrical box assembly, the electrical box assembly is mounted on the platform;

[0034] Solar radiation sensor 4 is mounted on the electrical box assembly and is positioned facing the sun.

[0035] The first end of the shield 2 is rotatably connected to the electrical box assembly and driven by the electrical box assembly. The second end of the shield 2 is set to correspond to the measurement area of ​​the solar radiation sensor 4.

[0036] While existing solar radiation measurement equipment can measure total radiation, it typically cannot simultaneously and accurately measure both direct and diffuse solar radiation, and suffers from drawbacks such as slow response, complex installation, and large size. In this application, the solar radiation sensor 4 on the electrical box assembly is adjusted by the platform to face the sunlight, enabling it to acquire the total solar radiation value. The main function of the shield 2 is to block the measurement area of ​​the solar radiation sensor 4, preventing direct sunlight from reaching its measurement area. The data processing unit inside the electrical box analyzes the intensity of direct and diffuse radiation. By analyzing the intensity of direct and diffuse radiation, the intensity of radiation directly reaching the ground from the sun can be accurately captured. Overall, this application has a simple structure, small size, and can simultaneously measure the intensity of both direct and diffuse solar radiation reaching the ground.

[0037] Further optimization of the solution, the electrical box assembly includes:

[0038] An integrated electrical box base plate 1 is installed on a solar tracking platform. A solar radiation sensor 4 is installed on the integrated electrical box base plate 1. The first end of a shield 2 is rotatably connected to the integrated electrical box base plate 1.

[0039] The motor (not shown in the figure) is installed in the integrated base plate 1 of the electrical box and is rotatably connected to the first end of the cover plate 2.

[0040] Position sensor 5 is mounted on the integrated base plate 1 of the electrical box and is set in correspondence with the cover plate 2.

[0041] The main function of the motor is to drive the shield 2 to rotate, causing the second end of the shield 2 to block or move away from the measurement area of ​​the solar radiation sensor 4. The main function of the position sensor 5 is to acquire the movement position of the shield 2 and transmit the position signal to the motor through the electrical box assembly, accurately controlling the movement position and blocking operation of the shield 2. In this application, the shield 2 and the electrical box assembly are used to achieve independent measurement of diffuse radiation and direct radiation. The position of the shield can be automatically controlled according to experimental requirements to block the influence of direct radiation, thereby measuring only diffuse radiation or only direct radiation. The shield 2, controlled by the motor, can accurately block the solar radiation sensor 4, control the area of ​​direct sunlight, and avoid interference from direct solar radiation on the measurement. The shield 2 is connected to the motor in the electrical box assembly to ensure accurate and rapid blocking operation.

[0042] Further optimizations to the plan include:

[0043] The semi-circular shading area 3 is set at the second end of the shield 2, and the semi-circular shading area 3 is set in correspondence with the measurement area of ​​the solar radiation sensor 4; this application is applicable to single-axis solar tracking platforms, dual-axis solar tracking platforms, and fixed-point test platforms; wherein, the fixed-point test platform is a test platform with a fixed position.

[0044] For a dual-axis solar tracking platform, when the semi-annular shading area 3 moves to the measurement area of ​​the solar radiation sensor 4 via the shield 2, sunlight shines onto the semi-annular shading area 3, effectively preventing direct radiation from the measurement area of ​​the solar radiation sensor 4, facilitating the acquisition of scattered radiation intensity signals. When the semi-annular shading area 3 is offset from the measurement area of ​​the solar radiation sensor 4, it facilitates the acquisition of total solar radiation intensity signals. For a single-axis solar tracking platform or a fixed-point testing platform, as the angle of sunlight changes throughout the day, the motor continuously drives the shield 2, ensuring that the semi-annular shading area 3 always blocks direct sunlight, suitable for scattered radiation intensity testing. Here, direct radiation intensity equals total radiation intensity minus scattered radiation intensity.

[0045] Further optimization of the design includes the following integrated electrical box mounting base plate 1:

[0046] The electrical box and mounting plate (not marked in the figure) are mounted on the platform via the mounting plate. The motor is installed inside the electrical box. The first end of the shield 2 is rotatably connected to the electrical box. The position sensor 5 is installed outside the electrical box, and the solar radiation sensor 4 is installed on the mounting plate. The electrical box assembly also includes a data processing unit, which is installed inside the electrical box and electrically connected to the solar radiation sensor 4, the position sensor 5, and the motor.

[0047] The electrical box maintains a relatively sealed state, making it suitable for harsh outdoor environments. It houses a power supply module, a communication module, and a data processing unit, ensuring stable operation in harsh conditions and supporting stable system operation while enabling real-time data acquisition and processing. The integrated design of the electrical box and mounting plate forms a compact and easy-to-install base plate 1, ensuring the stability of the internal electrical equipment during use. The mounting plate has mounting holes on its surface, allowing for integration with a solar tracking platform to adapt to different testing environments.

[0048] Further optimization of the design includes, for example, the integrated electrical box mounting base 1, which also includes:

[0049] A sealing ring (not shown in the figure) is installed at the rotating connection between the cover plate 2 and the electrical box;

[0050] Waterproof connector 6, several waterproof connectors 6 are installed on the side wall of the electrical box, and the signal lines of the data processing unit pass through several waterproof connectors 6.

[0051] The sealing ring and waterproof connector 6 further ensure the relatively sealed state of the electrical box, providing waterproof, dustproof, and corrosion-resistant functions, ensuring that the module can work stably in various harsh environments, especially suitable for outdoor use.
