Technical Field

[0001] The utility model belongs to the technical field of photovoltaic power generation, and in particular relates to a stable windproof and light-increasing device. Background Art

[0002] The existing ways of utilizing solar energy are mainly power generation and heat generation. In actual implementation, photovoltaic cells are generally used to generate electricity.

[0003] Bifacial photovoltaic modules are currently the most commonly used solar power generation devices.

The back is generally made of glass, that is, double-sided double glass, and there are also transparent backboard materials, which can reduce the overall weight of the module. Regardless of the material of the photovoltaic module, a reflector needs to be installed next to the photovoltaic panel. At present, the reflector is usually fixed on one side of the photovoltaic panel with an aluminum bracket, but the reflector is often subject to a large wind load, which can easily blow over or damage the entire reflector device.

BRIEF DESCRIPTION OF THE DRAWINGS

[0011] Figure 1 This is the front view of the light-enhancing device. DETAILED DESCRIPTION

[0012] The present invention will be further explained below in conjunction with the accompanying drawings to facilitate better understanding by those skilled in the art.

[0013] Example 1

[0014] like Figure 1 As shown, a stable windproof and light-enhancing device includes a reflector 1, which is installed on a reflector frame 2. The left end of the reflector frame 2 is hinged to the high end of the right side of a photovoltaic panel bracket 3, and the front and rear sides of the right end of the reflector frame 2 are hinged to two guide sleeves 4. A linear bearing 5 is fixedly connected in the guide sleeve 4, and a guide rod 6 is inserted into the linear bearing 5. The lower end of the guide rod 6 is hinged to an articulated seat 1 7, and a nut 8 is hinged to the middle part of the right end of the reflector frame 2. The nut 8 is spirally connected to a screw rod 9, and the lower end of the screw rod 9 is connected to a driving motor 10. The lower end of the motor seat of the driving motor 10 is hinged to an articulated seat 2 11, and the guide sleeve 4 and the nut 8 are coaxial with the articulation of the reflector frame 2. The articulated seat 1 7 and the articulated seat 2 11 are fixedly connected to the ground and the articulated axis is coaxial.

[0015] The driving motor 10 drives the screw rod 9 to rotate, driving the nut 8 to rise or fall, so as to adjust the inclination angle of the reflector 2. The reflector can be adjusted according to the sunlight to enhance the reflectivity. Among them, the reflector frame 2 is connected to the guide rod 6 through the guide sleeve 4 and the linear bearing 5, which not only has a limiting guiding function, but also is conducive to the screw 8 driving the left end of the photovoltaic panel bracket 3 to move up and down, and enhances the structural stability of the device. When the wind load is large, the controller controls the driving motor 10 to rotate according to the data collected by the wind speed sensor, so that the reflector 1 tends to be horizontal, effectively reducing the damage of the wind load to the reflector 1 and preventing it from tipping over.

[0016] The upper end of the guide rod 6 is provided with an anti-slip ring 12 to prevent the guide sleeve 4 from slipping off from the top end of the guide rod.

[0017] In order to facilitate the adjustment of the angle of the reflector 1 by raising or lowering the nut 8, the right end of the reflector frame 2 is hinged to the connecting ears 14 through a connecting seat 13, and the left end is hinged to two guide sleeves 4 and a nut 8 through three connecting ears 2 15.

[0018] A level sensor 16 is installed at the bottom of the reflector frame 2. The level sensor 16 and the drive motor are respectively connected to the signal receiving port and the control port of the controller. Another signal receiving port of the controller is connected to the wind speed sensor. The wind speed sensor is installed on the ground. When the wind speed reaches a set value, the controller controls the drive motor to lift the reflector. According to the signal feedback from the level sensor, when it reaches the level, the drive motor stops, thereby automatically realizing the windproof operation.

[0019] The above-mentioned embodiments are only for describing the preferred implementation of the utility model, and are not intended to limit the scope of the utility model. Without departing from the design spirit and principle of the utility model, various modifications and improvements made by those skilled in the art to the technical solution of the utility model shall fall within the protection scope determined by the claims of the utility model.
