Description

Technical Field

[0001] This utility model relates to the field of photovoltaic module technology, specifically to a mounting bracket with wind direction adjustment and a photovoltaic module. Background Technology

[0002] A photovoltaic (PV) module is a device that combines multiple solar cells in series and parallel and encapsulates them in a frame to directly convert solar energy into electrical energy. It is the core component of a photovoltaic power generation system. Solar cells are the basic power generation unit of a PV module. Multiple cells connected in series and parallel can meet different voltage and current requirements. PV modules are widely used in rooftop photovoltaic power generation, large-scale ground-mounted photovoltaic power stations, and other scenarios to provide people with clean and renewable electricity.

[0003] In the prior art, patent CN217461233U discloses a wind direction adjustment device for the protection of photovoltaic modules. It includes a mounting structure on a photovoltaic support and a wind duct fixed to the photovoltaic support via the mounting structure. The wind duct shields the bottom of the photovoltaic module from the higher end to the other. The air inlet of the wind duct is located at the higher end of the photovoltaic module, and the air outlet extends downwards and is lower than the lower end of the photovoltaic module. The photovoltaic support includes side supports connected to both sides of the photovoltaic module, each side support including an upright support member. The mounting structure includes connectors connecting adjacent support members. This invention avoids the problem of low wind resistance in the prior art when facing winds blowing from the higher end of the photovoltaic module, and the entire support structure has high strength and good reliability.

[0004] In the above technical solution, both the photovoltaic modules and the air duct are fixedly installed on the photovoltaic bracket. Since the angle of the photovoltaic panel is fixed, it cannot capture sunlight more efficiently. Even if the tilt angle of the photovoltaic panel can be adjusted, the air intake direction of the air duct is fixed, which cannot meet the wind direction adjustment operation of the photovoltaic panel under different tilt angles, thus failing to guarantee the stability of the photovoltaic module. Utility Model Content

[0005] The purpose of this utility model is to provide a mounting bracket and photovoltaic module with wind direction adjustment, which has the advantages of improving light energy conversion efficiency, improving the adaptability of wind direction adjustment mechanism, and ensuring the stability of photovoltaic module. It solves the problems of existing fixed photovoltaic modules and air ducts, low light energy conversion efficiency, and inability to guarantee the stability of photovoltaic modules.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] In a first aspect, this utility model provides an installation bracket with wind direction adjustment, including a base frame, a fixed frame fixedly connected to the upper surface of the base frame, and a motor installed on the fixed frame; a connecting frame is rotatably mounted on the motor, and the motor drives the connecting frame to rotate; a first wind direction adjustment mechanism and a second wind direction adjustment mechanism are installed on the connecting frame, and the first wind direction adjustment mechanism and the second wind direction adjustment mechanism can rotate synchronously with the connecting frame to change the airflow direction around the connecting frame.

[0008] As a preferred embodiment of the present invention, a rotating shaft is rotatably mounted on the fixed frame, and a fixing block is fixedly connected to both ends of the rotating shaft.

[0009] As a preferred embodiment of the present invention, the output end of the motor is fixedly connected to one end of the rotating shaft, and the fixing block is fixedly installed on the connecting frame.

[0010] As a preferred embodiment of the present invention, a first mounting bracket is fixedly installed at both ends of the connecting bracket.

[0011] As a preferred embodiment of the present invention, the first and second airflow adjustment mechanisms both include air ducts, the air inlets of the two air ducts are in opposite directions, and one end of the air inlet of each of the two air ducts is fixedly installed on the two first mounting brackets.

[0012] As a preferred embodiment of the present invention, a fan is fixedly installed inside the air inlet of the air duct via a third mounting bracket, and an air guide plate is fixedly connected inside the air duct, forming multiple airflow channels inside the air duct via the air guide plate.

[0013] As a preferred embodiment of the present invention, a second mounting bracket with wind direction adjustment is fixedly connected to the outside of the air guide duct, and sliding sleeves are fixedly connected to the outside of both ends of the second mounting bracket.

[0014] As a preferred embodiment of the present invention, a guide rod is fixedly connected to the upper end of the mounting bracket.

[0015] As a preferred embodiment of the present invention, the sliding sleeve is slidably fitted onto the guide rod.

[0016] Secondly, this utility model provides a photovoltaic module, including a mounting bracket with wind direction adjustment, on which a photovoltaic panel is fixedly mounted.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0018] 1. This utility model uses a motor to drive a rotating shaft, which in turn drives the connecting frame to rotate. The photovoltaic modules fixed on the connecting frame rotate accordingly, changing the angle of the photovoltaic panels so that they always face the sun to receive direct sunlight as much as possible. This not only improves the light energy conversion efficiency but also increases the daily power generation, overcoming the limitation of fixed installation brackets that cannot adapt to changes in the sun's altitude in different seasons.

[0019] 2. This utility model ensures the airflow effect on the photovoltaic panel by making the first and second airflow adjustment mechanisms rotate synchronously with the connecting frame, adjusting the direction of the air duct to adapt to different wind directions, promoting airflow through the fan, and changing the airflow direction through multiple airflow channels formed by the air guide plate, so as to optimize the airflow conditions around the photovoltaic panel, reduce wind resistance and avoid damage to the photovoltaic panel.

[0020] 3. By setting two wind direction adjustment mechanisms and making the air inlets of the two air ducts face opposite directions, this utility model can ensure that the side of the photovoltaic panel that is tilted to one side can be effectively adjusted by the wind direction, no matter which side the photovoltaic panel is tilted to.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium.

[0036] Please see Figures 1-8 An installation bracket with wind direction adjustment includes a base frame 1, a fixed frame 3 fixedly connected to the upper surface of the base frame 1, a motor 4 mounted on the fixed frame 3, a connecting frame 6 rotatably mounted on the motor 4, and a first wind direction adjustment mechanism 2 and a second wind direction adjustment mechanism 5 mounted on the connecting frame 6.

[0037] The mounting bracket with wind direction adjustment is used for photovoltaic modules. Its working principle mainly relies on the motor 4 driving the rotating shaft 11, which in turn drives the connecting frame 6 to rotate. The photovoltaic modules fixed on the connecting frame 6 rotate accordingly, changing the angle of the photovoltaic panel 9 so that it always faces the sun to receive direct sunlight as much as possible. This not only improves the light energy conversion efficiency, but also increases the daily power generation. The first wind direction adjustment mechanism 2 and the second wind direction adjustment mechanism 5 rotate synchronously with the connecting frame 6 to ensure the wind guidance effect on the photovoltaic panel 9.

[0038] A rotating shaft 11 is rotatably mounted on the fixed frame 3. Fixed blocks 10 are fixedly connected to both ends of the rotating shaft 11. The output end of the motor 4 is fixedly connected to one end of the rotating shaft 11. The fixed blocks 10 are fixedly mounted on the connecting frame 6. First mounting frames 7 are fixedly mounted on both ends of the connecting frame 6.

[0039] Specifically, there are two of each of the following components: base frame 1, fixing frame 3, connecting frame 6, first mounting frame 7, and fixing block 10. The two fixing frames 3 are fixedly installed on the two base frames 1 respectively, the two connecting frames 6 are fixedly installed on both sides of the photovoltaic panel 9 respectively, and the two fixing blocks 10 are fixedly installed on the outside of the two connecting frames 6 respectively. The rotating shaft 11 is rotatably installed inside the two fixing frames 3. The motor 4 is fixedly installed on one of the fixing frames 3. The output end of the motor 4 is fixedly connected to one end of the rotating shaft 11. The rotating shaft 11 is driven to rotate by the motor 4, so that the fixing block 10 and the connecting frame 6 rotate synchronously, thereby making the photovoltaic panel 9 rotate synchronously and realizing the angle adjustment of the photovoltaic panel 9. The first mounting frame 7 is used to fix the first wind direction adjustment mechanism 2 and the second wind direction adjustment mechanism 5, so that one end of the air guide pipe 21 is fixed to one end of the connecting frame 6 and can rotate synchronously with the connecting frame 6.

[0040] Both the first airflow adjustment mechanism 2 and the second airflow adjustment mechanism 5 include air ducts 21. The air inlets of the two air ducts 21 are in opposite directions. One end of the air inlet of the two air ducts 21 is fixedly installed on the two first mounting brackets 7 respectively. A fan 23 is fixedly installed inside the air inlet of the air duct 21 through a third mounting bracket 22. An air guide plate 24 is fixedly connected inside the air duct 21. Multiple airflow channels are formed inside the air duct 21 through the air guide plate 24.

[0041] The direction of the air duct 21 is adjusted to adapt to different wind directions. The fan 23 is placed inside the air inlet of the air duct 21, which can promote air flow and change the airflow direction through multiple airflow channels formed by the air guide plate 24, so as to optimize the airflow conditions around the photovoltaic panel 9, reduce wind resistance and avoid damage to the photovoltaic panel 9.

[0042] By setting up two wind direction adjustment mechanisms and making the air inlets of the two air ducts 21 face opposite directions, it can be ensured that the photovoltaic panel 9 can play a good wind direction adjustment role on the tilted side of the photovoltaic panel 9 no matter which side it is tilted to.

[0043] A second mounting bracket 8 is fixedly connected to the outside of the air duct 21. Sliding sleeves 13 are fixedly connected to the outside of both ends of the second mounting bracket 8. A guide rod 12 is fixedly connected to the upper end of the fixed bracket 3. The sliding sleeve 13 is slidably sleeved on the guide rod 12.

[0044] The guide rod 12 is arc-shaped and its two ends are fixedly installed on the lower surface of the upper end of the fixed frame 3. The sliding sleeve 13 slides with the guide rod 12 to ensure that the second mounting frame 8 and its components remain stable during rotation, preventing swaying or deviation from the preset position caused by wind or other external forces.

[0045] A photovoltaic module includes a mounting bracket with wind direction adjustment, and a photovoltaic panel 9 is fixedly mounted on a connecting frame 6.

[0046] By rotating the photovoltaic panel 9 onto the mounting bracket, it can better receive sunlight, ensuring efficient capture of sunlight throughout the year, overcoming the limitation of fixed mounting brackets that cannot adapt to changes in solar altitude in different seasons.

[0047] The working principle of this type of mounting bracket and photovoltaic module with wind direction adjustment is as follows:

[0048] The motor 4 drives the rotating shaft 11 to rotate, causing the fixed block 10 and the connecting frame 6 to rotate synchronously, thereby making the photovoltaic panel 9 rotate synchronously and realizing the angle adjustment of the photovoltaic panel 9. The first wind direction adjustment mechanism 2 and the second wind direction adjustment mechanism 5 rotate synchronously with the photovoltaic panel 9. The fan 23 promotes the air flow around the photovoltaic panel 9, and the airflow direction is changed by multiple wind direction channels formed by the wind guide plate 24 to optimize the air flow conditions around the photovoltaic panel 9, reduce wind resistance and avoid damage to the photovoltaic panel 9, and improve the stability of the photovoltaic panel 9.
