Description

Technical Field

[0001] This utility model belongs to the field of photovoltaic module testing technology, specifically a weather resistance testing device for flexible photovoltaic modules. Background Technology

[0002] The weather resistance testing device for flexible photovoltaic modules is a device used to simulate complex outdoor environments (such as strong winds, ultraviolet radiation, temperature cycling, and humid conditions). By comprehensively adjusting parameters, it evaluates the material aging, coating degradation, and electrical performance decline of flexible photovoltaic modules during long-term use, as well as their curling or folding states in practical applications, ensuring that the test covers a variety of usage scenarios. Its application areas include building-integrated photovoltaics (BIPV), mobile energy devices (such as drones and RVs), and lightweight portable power supplies, providing key data support for the reliability verification and product optimization of flexible photovoltaic modules.

[0003] Existing weather resistance testing equipment for flexible photovoltaic modules cannot comprehensively test their weather resistance under high wind conditions, given the complexity of the environment, resulting in poor testing performance. Utility Model Content

[0004] In order to overcome the shortcomings of the prior art, this utility model provides a weathering resistance testing device for flexible photovoltaic modules, which effectively solves the problem that the existing weathering resistance testing devices for flexible photovoltaic modules cannot detect the weathering resistance under strong wind conditions from multiple perspectives according to complex environmental conditions, and their testing results are not good.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a weather resistance testing device for flexible photovoltaic modules, comprising a workbench, with support frames fixedly installed at both ends of the workbench, and support plates fixedly installed at both ends of the top of the workbench. A circular opening is provided in the middle of each of the two support plates. Two steel wire ropes are fixedly installed between the two support frames on their adjacent sides, and the two steel wire ropes are positioned between the two circular openings. Four positioning hoops are fixedly installed on the surface of the two steel wire ropes. A photovoltaic panel is detachably installed between the tops of the four positioning hoops. A blower is provided below the photovoltaic panel, and a blower head is fixedly installed on the top of the blower. Several air outlet holes are provided on the upper surface of the blower head. A drive motor is fixedly installed in the middle of the bottom of the workbench. A transmission component is provided at the output end of the drive motor. The transmission component is connected to the blower. When the drive motor operates, it outputs power to the blower through the transmission component, causing the blower to rotate and adjust the blowing direction.

[0006] Preferably, the transmission assembly includes a driving bevel gear, which is fixedly installed at the output end of the drive motor. A driven bevel gear is meshed with one side of the surface of the driving bevel gear. A shaft is fixedly installed in the middle of the driven bevel gear. Two bearings are rotatably installed on the surface of the shaft. The upper parts of the two bearings are fixedly connected to the inner top of the worktable through a fixing head. Transmission gears are fixedly installed at both ends of the shaft. The sides of the two transmission gears that are far apart from each other are rotatably connected to the inner walls of both ends of the worktable through a positioning shaft seat.

[0007] Preferably, the upper part of each of the transmission gears is meshed with an external gear ring, and the lower part of each of the two external gear rings is fixedly installed with a support arm on the side close to each other. The ends of the two support arms that are close to each other are fixedly connected to the two ends of the blower head.

[0008] Preferably, four connecting rods are fixedly installed at equal intervals in an annular pattern on the sides of the two external gear rings that are far apart from each other. Limiting slip rings are fixedly installed between one end of each of the four connecting rods on the same external gear ring. Annular grooves are opened on the sides of the two support plates that are close to each other. The two limiting slip rings are slidably installed inside the two annular grooves.

[0009] Compared with the prior art, the beneficial effects of this utility model are as follows: During testing, the operator fixes the photovoltaic panel to the four positioning hoops on the two steel wire ropes, and then starts the drive motor to drive the active bevel gear to rotate. When the active bevel gear rotates, it drives the shaft to rotate inside the two bushings through the driven bevel gear. When the two shafts rotate, they drive the two transmission gears to rotate along the two positioning shaft seats.

[0010] When the two transmission gears rotate, they drive the two external gear rings to rotate. Each of the two external gear rings rotates via four connecting rods, causing a limiting slip ring to slide within an annular groove, ensuring stability during rotation. The rotation of the two external gear rings also drives the blower head and blower via two support arms, allowing for multi-directional airflow adjustment as needed. The blower is then activated, blowing air through several outlet holes to test the photovoltaic panel. This allows the flexible photovoltaic module weather resistance testing device to perform multi-directional testing of weather resistance under high wind conditions, adapting to complex environments and demonstrating excellent testing performance.

A transmission component is provided at the output end of the drive motor 23. The transmission component is connected to the blower 8. When the drive motor 23 is running, it outputs power to the blower 8 through the transmission component, causing the blower 8 to rotate and adjust the blowing direction.

[0021] During testing, the operator fixes the photovoltaic panel 7 to the four positioning hoops 6 on the two steel wire ropes 5, and then starts the drive motor 23 to drive the transmission component to rotate. When the transmission component rotates, it drives the blower head 9 and the blower 8 to rotate, so that the wind direction can be adjusted in multiple directions as needed. Then, the blower 8 is started to blow air out through several air outlets 10 to test the photovoltaic panel 7. This allows the weather resistance testing device of this flexible photovoltaic module to detect the weather resistance under strong wind conditions in multiple directions according to complex environmental conditions, and has good testing effect.

The sides of the two transmission gears 17 that are far apart from each other are rotatably connected to the inner walls of both ends of the worktable 1 through a positioning shaft seat 18.

[0023] The start-up drive motor 23 drives the active bevel gear 11 to rotate. When the active bevel gear 11 rotates, it drives the shaft 13 to rotate inside the two bushings 14 through the driven bevel gear 12. When the two shafts 13 rotate, they drive the two transmission gears 17 to rotate along the two positioning shaft seats 18.

[0024] The upper part of the transmission gear 17 is meshed with an external gear ring 19. The lower part of the two external gear rings 19, which are close to each other, is fixedly installed with a support arm 20. The two support arms 20, which are close to each other, are fixedly connected to the two ends of the blower head 9.

[0025] When the two transmission gears 17 rotate, they drive the two external gear rings 19 to rotate. When the two external gear rings 19 rotate, they drive the blower head 9 and the blower 8 to rotate through the two support arms 20, so that the air direction can be adjusted in multiple directions as needed.

[0026] Four connecting rods 21 are fixedly installed at equal intervals in a ring on the side of the two external gear rings 19 that are far apart from each other. Limiting slip rings 22 are fixedly installed between one end of the four connecting rods 21 on the same external gear ring 19.
