Description

Technical Field

[0001] The utility model application relates to the technical field of brackets, specifically to a wind-resistant bracket for photovoltaic panels. Background Art

[0002] Photovoltaic panels, also known as solar panels, are devices that use solar energy to convert light energy into electrical energy. They are mainly composed of solar cells. These cells convert sunlight radiation into electrons through the photovoltaic effect, which then forms an electric current. The photovoltaic effect refers to when light shines on a semiconductor material, such as silicon, it causes electrons on the surface of the material to break away from atoms and form an electric current. The structure of a photovoltaic cell usually consists of two layers of differently doped silicon to form a pn junction. When light shines on the pn junction, more electrons are excited, thereby increasing the intensity of the current.

[0003] With the transformation of the global energy structure, photovoltaic power generation technology has been widely used. However, wind force poses a serious threat to the stability and safety of photovoltaic panels and their brackets. Photovoltaic panel brackets in the existing technology often have the problem of insufficient wind resistance, which makes photovoltaic panels easily damaged or even cause safety accidents in strong wind environments. Therefore, the development of a photovoltaic panel bracket with high-efficiency wind resistance has become an urgent problem to be solved. Summary of the invention

[0004] In order to solve the problem that photovoltaic panel brackets in the prior art often have insufficient wind resistance, which causes the photovoltaic panels to be easily damaged in strong wind environments or even cause safety accidents, the utility model provides a photovoltaic panel wind-resistant bracket to solve the above problem.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] The photovoltaic panel wind-resistant support comprises a photovoltaic panel body, an upper support and legs, wherein the photovoltaic panel body is arranged on the top of the upper support, four legs are arranged on the bottom of the upper support, a bottom plate is fixed to the bottom of the legs, a connecting frame is fixed to the middle of the bottom plate, two limit blocks are symmetrically fixed to the top surface of the connecting frame, a turntable is rotatably connected to the center of the top surface of the connecting frame, a wind direction plate is fixed to the top of the turntable, and second guide plates are symmetrically fixed to both sides of the top surface of the bottom plate.

[0007] Furthermore, inner sleeve rods are fixed on both sides of the outside below each leg, and outer sleeve rods corresponding to the inner sleeve rods are fixed to the bottom end of the outside of the base plate. The inner sleeve rods are slidably connected to the inside of the outer sleeve rods, and a spring is fixed inside the outer sleeve rods.

[0008] Furthermore, two first guide plates are symmetrically arranged between the connecting frame and the upper bracket, the top ends of the first guide plates are fixedly connected to the upper bracket, and the bottom ends of the first guide plates are fixedly connected to the connecting frame.

[0009] Furthermore, two airflow plates are rotatably connected to the first air guide plate, and the first air guide plate is provided with slots matching the shapes of the airflow plates.

[0010] Furthermore, guide strips are fixed on both sides of the wind deflector, and the outer surface of the second guide plate is designed to be arc-shaped.

[0011] Furthermore, the radius of the inner sleeve rod is smaller than the radius of the inner circle of the outer sleeve rod, one end of the spring is fixed to the inner bottom end of the outer sleeve rod, and the other end of the spring is fixed to an end of the inner sleeve rod away from the support leg.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] 1. In the utility model, a wind direction plate is arranged below the photovoltaic panel body, and a first guide plate and a second guide plate are symmetrically arranged, so that when the wind passes below the photovoltaic panel body, the wind direction plate, the first guide plate and the second guide plate guide the airflow to both sides of the photovoltaic panel body. At the same time, the surface of the second guide plate is provided with an arc, and the first guide plate is provided with an airflow plate, so that when the wind blows on the side of the photovoltaic panel body, the airflow is diverted by the second guide plate and the airflow plate to avoid the wind direction directly acting on the bottom end of the photovoltaic panel body, thereby solving the problem that the photovoltaic panel bracket in the prior art often has insufficient wind resistance, which makes the photovoltaic panel easily damaged in a strong wind environment or even causes a safety accident.

[0014] 2. In the utility model, inner sleeve rods and outer sleeve rods are arranged at the bottom ends of the four legs. When the photovoltaic panel body is blown by the wind, it generates vibrations. At this time, the inner sleeve rod contracts toward the inside of the outer sleeve rod. At the same time, the vibration generated is absorbed by the spring. The spring then reacts to push the inner sleeve rod outward, thereby reducing the vibration of the photovoltaic panel body and making the photovoltaic panel body more resistant to wind and earthquake.

[0021] In order to make the purpose, features, and advantages of the present application more obvious and easy to understand, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the embodiments described below are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0022] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4 The photovoltaic panel wind-resistant support comprises a photovoltaic panel body 1, an upper support 2 and a leg 3. The photovoltaic panel body 1 is arranged on the top of the upper support 2, and four legs 3 are arranged on the bottom of the upper support 2. A bottom plate 5 is fixed to the bottom of the leg 3, and a connecting frame 6 is fixed to the middle of the bottom plate 5. A turntable 7 is rotatably connected to the top center of the top surface of the connecting frame 6, and a wind deflector 8 is fixed to the top of the turntable 7. Two limit blocks 10 are symmetrically fixed on the top surface of the connecting frame 6, and second guide plates 13 are symmetrically fixed on both sides of the top surface of the bottom plate 5, so that the wind deflector 8 and the second guide plate 13 can divert the airflow.

[0023] Specifically, two first guide plates 11 are symmetrically arranged between the connecting frame 6 and the upper bracket 2. The top end of the first guide plate 11 is fixedly connected to the upper bracket 2, and the bottom end of the first guide plate 11 is fixedly connected to the connecting frame 6, so that the first guide plate 11 further diverts the airflow. Two airflow plates 12 are rotatably connected to the first guide plate 11. The first guide plate 11 is provided with a groove that matches the shape of the airflow plate 12, so that the first guide plate 11 guides the side airflow to the wind direction plate 8. Guide strips 9 are fixed on both sides of the wind direction plate 8. Guide strips 9 are fixed on both sides of the wind direction plate 8. A triangular inclined surface is provided on the side of the guide strip 9 away from the wind direction plate 8, and an inclined surface is provided on the end of the guide strip 9 close to the rear of the photovoltaic panel body 1, so that the diversion effect of the wind direction plate 8 and the second guide plate 13 is better.

[0024] As an optimization solution, Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, inner sleeve rods 14 are fixed on both sides of the outside of each leg 3, and outer sleeve rods 4 corresponding to the inner sleeve rods 14 are fixed on the top of the outside of the base plate 5. The inner sleeve rods 14 are slidably connected to the inside of the outer sleeve rods 4, and springs 15 are fixed inside the outer sleeve rods 4, which improves the seismic resistance of the legs 3.

[0025] Specifically, the radius of the inner sleeve rod 14 is smaller than the radius of the inner circle of the outer sleeve rod 4, one end of the spring 15 is fixed to the bottom end inside the outer sleeve rod 4, and the other end of the spring 15 is fixed to the end of the inner sleeve rod 14 away from the support leg 3, so that the inner sleeve rod 14 slides inside the outer sleeve rod 4.

[0026] Working principle: When the wind blows behind the photovoltaic panel body 1, part of the airflow is first diverted to the two sides of the photovoltaic panel body 1 by the second guide plate 13, and the other part of the airflow enters the inside of the photovoltaic panel body 1, and then is diverted to the two sides of the photovoltaic panel body 1 and the middle of the photovoltaic panel body 1 by the first guide plate 11. At the same time, when the airflow blows the wind direction plate 8, the airflow drives the wind direction plate 8 to move, so that the wind direction plate 8 drives the turntable 7 to rotate. At this time, the wind direction plate 8 is parallel to the airflow streamline. At the same time, the triangular inclined surface on the side of the guide strip 9 breaks the airflow and then guides the airflow downward, so that the airflow flows out from the bottom of the front end of the photovoltaic panel body 1. When the wind blows on the side of the photovoltaic panel body 1, part of the airflow is guided to the rear of the photovoltaic panel body 1 by the second guide plate 13, and the other part of the airflow flows to the rear of the photovoltaic panel body 1. Through the slot on the first guide plate 11, the airflow drives the airflow plate 12 to rotate and open, so that the airflow passes through the slot on 11 and flows to the inside of the photovoltaic panel body 1, and then the airflow drives the wind direction plate 8 to move, so that the wind direction plate 8 drives the turntable 7 to rotate. At the same time, when the turntable 7 rotates, the limit blocks 10 on both sides limit the wind direction plate 8, so that the rotation angle of the wind direction plate 8 is limited, so that the wind direction plate 8 guides the airflow to the bottom of the front end of the photovoltaic panel body 1. At the same time, when the photovoltaic panel body 1 is blown by the wind, the support leg 3 will vibrate. At this time, the support leg 3 pushes the inner sleeve rod 14, so that the inner sleeve rod 14 slides toward the inside of the outer sleeve rod 4. At the same time, the spring 15 is compressed and rebounds, pushing the inner sleeve rod 14 to the outside, thereby offsetting the vibration generated by the support leg 3.
