Description

Technical Field

[0001] This invention relates to the field of photovoltaic panel testing technology, specifically to a device for testing the performance of solar panels. Background Technology

[0002] Photovoltaics, short for solar photovoltaic power generation system, is a new type of power generation system that uses the photovoltaic effect of solar cell semiconductor materials to directly convert solar radiation energy into electrical energy. The production of solar panels generally includes: cleaning and texturing, diffusion process, etching process, PECVD technology, screen printing technology, and sintering process. Among them, the texturing process in cleaning and texturing uses an alkaline solution to anisotropically etch silicon wafers to create a textured surface, forming dense and uniform "pits". This is the key to the efficiency of converting sunlight into electrical energy. The uniformity of the "pits" on the textured surface directly reflects the power generation capacity of the solar panel: uneven "pits" result in high reflectivity, low light transmittance, and low power generation capacity of the solar panel.

[0003] A search revealed a publicly available announcement (CN106712718A) for a solar panel light transmittance testing device, comprising a base on which a bracket I and a stepper motor are mounted; an encoder is connected to the stepper motor's input interface, and the encoder sends signals to a controller; a placement platform, the two symmetrical sides of which are fixedly connected to the ends of a rotating rod fitted with a gear II via support arms; at least one lamp is located directly above the placement platform; a light-shielding box is installed on one side of the placement platform, and a light-shielding cloth is installed inside; a linear motor is installed on the side of the placement platform opposite to the photoelectric sensor, and its input interface is connected to the controller via an RS-485 line; a wiring port is fixed on the placement platform, one end of which is connected to the positive and negative terminals of the junction box of the solar panel being tested, and the other end is connected to a voltage and current recorder.

[0004] Photovoltaic panels, also known as solar panels, are devices that directly convert solar energy into electrical energy. They are the core component of solar power generation systems and are widely used in residential, commercial, and industrial fields. Utilizing solar energy for power, they eliminate the need for an external power source, saving energy and being environmentally friendly. Solar water level monitoring instruments are devices that use solar energy to monitor water level changes and support 24-hour uninterrupted monitoring with real-time data transmission. To ensure production quality, several groups of solar photovoltaic panels need to be randomly selected from each batch of products for quality inspection. Currently, when inspecting photovoltaic equipment, workers need to drive the testing equipment close to the photovoltaic panel and connect it to the photovoltaic converter on the panel to detect information such as current, voltage, power, and temperature. However, the reliability of the measurement data obtained by the aforementioned publicly available devices cannot be guaranteed under different conditions, which may lead to errors in the measured data and affect the final measurement results. Summary of the Invention

[0028] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0029] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0030] Reference Figures 1-3 A device for testing the performance of solar panels includes a base plate 1, on which four parallel support columns 11 are fixedly mounted, and on each support column 11 a bearing plate 2 is fixedly mounted, and on the bearing plate 2 a conversion mechanism for collecting and storing solar energy is fixedly mounted.

[0031] The conversion mechanism includes two parallel support plates 6 fixedly mounted on the support plate 2. A connecting shaft 62 is rotatably mounted on the top of the two support plates 6. A photovoltaic panel 63 for absorbing light energy is rotatably mounted on the connecting shaft 62. Two adjacent photovoltaic panels 63 are rotatably connected, and each photovoltaic panel 63 is connected to the others through a long plate 65. A control component for adjusting the opening and closing angle of the conversion mechanism is provided at the bottom of the support plate 6.

[0032] A fixed column 5 is fixedly installed on the support plate 2. Two parallel vertical plates 53 are fixedly installed on the output end of the fixed column 5. An infrared emitting rod 54 is rotatably installed between them. The orientation of the infrared emitting rod 54 is aligned with the photovoltaic panel 63.

[0033] Reference Figure 1 , Figure 3 and Figure 4 A control shaft 7 is rotatably mounted on the support plate 2. A first outer shell 3 is fixedly mounted on the control shaft 7. A second outer shell 31 and a third outer shell 32 are rotatably mounted on the control shaft 7. The second outer shell 31 and the third outer shell 32 are sleeved on the outer end of the first outer shell 3. An adjustment rod 33 for positioning is fixedly mounted on the outer wall of the first outer shell 3. Multiple evenly arranged light emitters 34 are fixedly mounted on the inner wall of the first outer shell 3. Through the first outer shell 3, the second outer shell 31 and the third outer shell 32 mounted on the control shaft 7, when the operator adjusts the rotation of the first outer shell 3, the control shaft 7 fixedly connected to it also starts to rotate. Furthermore, since the first outer shell 3, the second outer shell 31 and the third outer shell 32 are coaxially mounted, they can cover and wrap the photovoltaic panel 63 inside the support plate 2 when fully unfolded, which facilitates the maintenance of the photovoltaic panel 63.

[0034] Reference Figures 5-7 A disc 71 is fixedly installed at the edge of each of the outer shells 3, 31, and 32. A locking strip 71 is fixedly installed on one side of the disc 71, and a locking strip 712 matching the locking strip 71 is fixedly installed on the other side of the disc 71. By using the locking strip 711 on one side of the disc 71 and the locking strip 712 on the other side of the disc 71, when the outer shell 3 rotates, the disc 71 fixedly connected to the outer shell 3 rotates, thereby driving the locking strip 711 on its outer surface to rotate. As the locking strip 711 rotates, it gradually approaches the locking strip 712 on the other disc 71. When the locking strip 711 rotates to a certain angle, the locking strip 711 and the locking strip 712 come into contact. At this time, when the original disc 71 is rotated, the other disc 71 adjacent to it will also rotate. By continuing the above operation, the outer shells 3, 31, and 32 can be fully unfolded.

[0035] Reference Figures 2-4The control component includes a cylinder 61 rotatably disposed between two support plates 6, a control plate 64 fixedly disposed on the cylinder 61, and the control plate 64 being movably connected to the photovoltaic panel 63. By disposing of the cylinder 61 between the two support plates 6, when the operator controls the cylinder 61 to rotate, the control plate 64 fixedly connected to it rotates, thereby controlling the photovoltaic panel 63 to unfold.

[0036] Reference Figures 6-8 Two parallel brackets 21 are fixedly mounted on the lower end face of the bearing plate 2. A rotating shaft 211 is rotatably mounted between the two brackets 21. A pulley 212 is fixedly mounted on one end of the control shaft 7 and the rotating shaft 211. The two pulleys 212 are connected by a belt drive. A pulley 611 is fixedly mounted on the other end of the cylinder 61 and the rotating shaft 211. The two pulleys 611 are connected by a belt drive. Through the two brackets 21 mounted on the bearing plate 2 and the rotating shaft 211 rotatably mounted between the two brackets 21, the pulley 212 fixed on its outer circumference rotates when the control shaft 7 rotates. The rotating pulley 212 drives the pulley 212 on the rotating shaft 211 to rotate through the belt, thereby driving the rotating shaft 211 to rotate. During the rotation of the rotating shaft 211, the cylinder 61 is driven to rotate through the pulley 611.

[0037] Reference Figure 1 , Figure 7 and Figure 8 A positioning ring 4 is fixedly installed on the bearing plate 2, and two parallel brackets 621 are fixedly installed on the connecting shaft 62. A shaft is rotatably installed between the two brackets 621. The movement of the infrared emitting rod 54 is controlled by the positioning ring 4 on the bearing plate 2 and the brackets 621 on the connecting shaft 62.

[0038] Reference Figures 6-8 A turntable 51 is rotatably mounted on the outer circumferential surface of the fixed column 5. A sliding plate 511 is fixedly mounted on the turntable 51. The sliding plate 511 is arc-shaped. A chuck 541 is fixedly mounted on the outer circumferential surface of the infrared emitting rod 54. The chuck 541 and the sliding plate 511 are engaged with each other. Through the turntable 51 mounted on the fixed column 5, the infrared emitting rod 54 can be controlled to move up and down by the chuck 541 during the movement of the sliding plate 511, so as to realize the comprehensive inspection of the photovoltaic panel 63.

[0039] Reference Figures 6-8 A second bracket 513 is fixedly installed on the lower end surface of the turntable 51. A connecting rod 52 is rotatably installed on the second bracket 513. The other end of the connecting rod 52 is rotatably connected to the third bracket 621. The second bracket 513 installed on the turntable 51 can control the rotation of the turntable 51 when the connecting rod 52 moves.

[0040] Reference Figures 1-3 A hinge 66 is fixedly connected between two adjacent photovoltaic panels 63, which facilitates the connection and control of the photovoltaic panels 63.

[0041] Reference Figures 5-7 The outer shell 3, outer shell 31 and outer shell 32 are all arc-shaped, and the outer shell 3, outer shell 3, outer shell 3, and outer shell 32 are made of PMMA material with high light transmittance. By setting the outer shell 3, outer shell 2, and outer shell 32 to be made of a material with high light transmittance, the photovoltaic panel 63 is protected while ensuring the light energy conversion efficiency of the device.

[0042] Specifically, the solution is as follows: When using the device, the operator first moves it to a suitable position. The support columns 11 on the base plate 1 ensure the overall stability of the device. Through the outer shell 3, outer shell 31, and outer shell 32 mounted on the control shaft 7, when the operator adjusts the rotation of outer shell 3, the control shaft 7, which is fixedly connected to it, also begins to rotate. Furthermore, because outer shell 3, outer shell 31, and outer shell 32 are coaxially arranged, they can cover and wrap the photovoltaic panel 63 inside the support plate 2 when fully unfolded, facilitating the maintenance of the photovoltaic panel 63. The locking strip 711 on one side of the disc 71 and the locking strip 712 on the other side of the disc 71 enable... During the rotation of outer shell 3, the disk 71 fixedly connected to outer shell 3 rotates, thereby driving the locking strip 711 on its outer surface to rotate. During the rotation of locking strip 711, it will gradually approach locking strip 712 on another disk 71. When locking strip 711 rotates to a certain angle, locking strip 711 and locking strip 712 will fit together. At this time, when the original disk 71 is rotated, the other disk 71 adjacent to it will also rotate. Continuing the above operation will allow outer shell 3, outer shell 31 and outer shell 32 to be fully unfolded. The positioning ring 4 set on the bearing plate 2 and the bracket 621 set on the connecting shaft 62 realize the control of the movement of the infrared emitting rod 54.
