Description

Technical Field

[0001] The utility model belongs to the technical field of photovoltaic power generation, and in particular relates to a light-enhancing device capable of absorbing wind load. 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 most intuitive thing is that the back of the photovoltaic module can also generate electricity. 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. Utility Model Content

[0004] The purpose of the utility model is to provide a light-enhancing device capable of absorbing wind loads to solve the above technical problems.

[0005] The technical solution adopted by the utility model is a light-enhancing device capable of absorbing wind loads, comprising a reflector, the reflector being mounted on a reflector frame, the right end of the reflector frame being hinged to the lower end of the left side of the photovoltaic panel bracket, a nut being hinged to the middle of the left end of the reflector frame, the nut being spirally connected to a lead screw, the lower end of the lead screw being connected to a drive motor, the lower end of a motor seat of the drive motor being hinged to a second hinge seat, and the second hinge seat being fixedly connected to the ground.

[0006] Preferably, the right end of the reflector frame is hinged to the connecting ears 1 through the connecting seat 1, and the left end is hinged to the nut through the connecting ears 2.

[0007] Preferably, a level sensor is installed at the bottom of the reflective plate frame.

[0008] Preferably, the reflective plate reflects sunlight to the back side of an adjacent photovoltaic panel.

[0009] Compared with the prior art, the beneficial effect of the utility model is that, by hingedly connecting the two ends of the reflective board frame to the photovoltaic panel bracket and the nut respectively, the nut is connected to the screw rod, and the drive motor drives the screw rod to rotate, driving the nut to rise or fall, so as to adjust the inclination angle of the reflective board. Not only can the reflective board be adjusted according to sunlight to enhance the reflectivity, but also when the wind load is large, the controller controls the rotation of the drive motor according to the data collected by the wind speed sensor, so that the reflective board tends to be horizontal, absorbs the wind load, reduces the damage of the wind load to the device, and avoids the reflective board being blown over. BRIEF DESCRIPTION OF THE DRAWINGS

[0010] Figure 1This is the front view of the light-enhancing device. DETAILED DESCRIPTION

[0011] The present invention will be further explained below in conjunction with the accompanying drawings to facilitate better understanding by those skilled in the art.

[0012] Example 1

[0013] like Figure 1 As shown, a light-enhancing device capable of absorbing wind loads comprises a reflector 1, which is mounted on a reflector frame 2, the right end of the reflector frame 2 is hinged to the lower end of the left side of a photovoltaic panel bracket 3, a nut 8 is hinged to the middle of the left end of the reflector frame 2, the nut 8 is spirally connected to a screw rod 9, the lower end of the screw rod 9 is connected to a drive motor 10, the lower end of a motor seat of the drive motor 10 is hinged to an articulated seat 11, and the articulated seat 11 is fixedly connected to the ground.

[0014] Furthermore, the right end of the reflector frame 2 is hinged to the connecting ears 14 through the connecting seat 13, and the left end is hinged to the nut 8 through the connecting ears 2 15.

[0015] The reflector 2 is used in an inclined state to reflect sunlight to the back of the adjacent photovoltaic panel.

[0016] The two ends of the reflector frame 2 are respectively hinged with the photovoltaic panel bracket 3 and the nut 8, the nut 8 is connected to the screw rod 9, and the drive motor 10 drives the screw rod 9 to rotate, driving the nut 8 to rise or fall, thereby adjusting the inclination angle of the reflector 2. The angle of the reflector 1 can be adjusted according to the season, so that the sunlight can be reflected to the back of the double-sided double-glass photovoltaic panel adjacent to the reflector to the maximum extent, so as to increase the power generation.

[0017] Among them, a level sensor 16 is installed at the bottom of the reflector frame 2. The level sensor 16 and the drive motor 10 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 10 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.

[0018] 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.
