Description

Technical Field

[0001] The present invention relates to the field of photovoltaic supports, and in particular to a photovoltaic support vibration suppression device and a photovoltaic support vibration suppression method. Background Art

[0002] In patent document CN207490846U, the photovoltaic panels on the crossbeams are arranged in parallel. When encountering strong winds, the airflow will directly act on the surface of the photovoltaic panels, resulting in a large torque on the photovoltaic panels and a slight change in the inclination of the photovoltaic panels. The change in the inclination of the photovoltaic panels will cause changes in the wind load, and the change in wind load will in turn affect the wind load. Under such mutual coupling, the photovoltaic panels will undergo large-scale torsional vibrations, and the more violent the change in the torsion of the photovoltaic panels with the inclination angle, the more likely it is to undergo large-scale torsional vibrations, thereby causing serious damage to the photovoltaic panels.

[0003] In the patent document CN114094923A, a telescopic structure is provided between the photovoltaic panel and the auxiliary photovoltaic panel. When encountering strong winds, the auxiliary photovoltaic panel can be folded up by the telescopic structure, thereby reducing the size of the windshield of the photovoltaic power generation frame and reducing the probability of twisting of the photovoltaic power generation frame. The structure may not undergo significant twisting under strong wind conditions with lower wind speeds, but when encountering strong winds with higher wind speeds, the photovoltaic panel and the auxiliary photovoltaic panel will experience significant torsional vibration due to the large wind pressure energy acting on the surface of the photovoltaic panel and nowhere to release it, thereby causing wind-induced torsional instability and damage to the photovoltaic panel and the auxiliary photovoltaic panel.

[0004] After carefully studying the above documents, the applicant found that when the photovoltaic bracket adopts the above-mentioned form, its torque changes dramatically with the inclination angle when encountering strong winds, and it is easy to have large-scale torsional vibrations, which will cause wind-induced torsional instability and damage to the photovoltaic bracket and photovoltaic components. Therefore, how to reduce the torque of the photovoltaic bracket, suppress the large-scale torsional vibration of the photovoltaic bracket, and reduce the damage to the photovoltaic bracket has become a technical problem that technical personnel in this field urgently need to solve. Summary of the Invention

[0005] The purpose of the present invention is to provide a photovoltaic bracket vibration suppression device and a photovoltaic bracket vibration suppression method to solve the problems existing in the above-mentioned prior art. By arranging multiple rows of photovoltaic panel assembly integrations including multiple photovoltaic panel assemblies arranged in sequence on the photovoltaic bracket at intervals, when the photovoltaic bracket encounters strong winds, the airflow can flow through the wind leakage channel formed between adjacent photovoltaic panel assembly integrations, changing the wind pressure distribution on the surface of the photovoltaic panel assembly integration, reducing the torque of the photovoltaic panel assembly integration, and slowing down the change of the torque of the photovoltaic panel assembly integration with the inclination angle, thereby suppressing the vibration of the photovoltaic panel assembly integration, and setting the ratio of the row height of the photovoltaic panel assembly integration to the row height of the wind leakage channel to 14 to 20:1, which further reduces the torque of the photovoltaic panel assembly integration, slows down the change of the torque of the photovoltaic panel assembly integration with the inclination angle, thereby further reducing the vibration of the photovoltaic panel assembly integration.

[0018] The fluid flowing from the windward side to the leeward side of the photovoltaic panel assembly integration has part of the fluid flowing out from the air leakage channel when passing through the photovoltaic panel assembly integration, thereby changing the wind pressure distribution on the windward side of the photovoltaic panel assembly integration.

The ratio of the row height of the photovoltaic panel assembly integration to the row height of the wind leakage channel is set at 14 to 20:1, which further reduces the torque of the photovoltaic panel assembly integration, slows down the change of the torque of the photovoltaic assembly integration with the inclination angle, and thus further reduces the vibration of the photovoltaic panel assembly integration.

[0033] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0034] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0035] like Figure 1 As shown, when the traditional photovoltaic panel assembly integration 1 is arranged, there is no gap between the two photovoltaic panel assembly integrations 1. When encountering strong winds, the airflow will directly act on the surface of the photovoltaic panel assembly integration 1, resulting in a large torque of the photovoltaic panel assembly integration 1 and a slight change in the inclination angle of the photovoltaic panel assembly integration 1. The change in the inclination angle of the photovoltaic panel assembly integration 1 will cause a change in the wind load, and the change in wind load will in turn affect the wind load. Under such mutual coupling, the photovoltaic panel assembly integration 1 will undergo large-scale torsional vibration, and the more violent the torsion of the photovoltaic panel assembly integration 1 changes with the inclination angle, the more likely it is to undergo large-scale torsional vibration, and the more likely the photovoltaic panel assembly integration 1 will be seriously damaged.

[0036] The present invention provides a photovoltaic support vibration suppression device, such as Figure 2 As shown, the device includes a photovoltaic bracket, and a plurality of rows of photovoltaic panel assembly integrations 1 spaced apart on the photovoltaic bracket, the photovoltaic panel assembly integration 1 includes a plurality of photovoltaic panel assemblies 2 arranged in sequence, and an air leakage channel 3 is formed between adjacent photovoltaic panel assembly integrations 1, so that when the photovoltaic panel assembly integration 1 encounters strong winds, air can flow in and out of the air leakage channel 3, thereby changing the surface wind pressure distribution of the photovoltaic panel assembly integration 1 and the photovoltaic bracket, and reducing the torque of the photovoltaic panel assembly integration 1 and the photovoltaic bracket, slowing down the change of the torque of the photovoltaic panel assembly integration 1 and the photovoltaic bracket with the inclination angle, thereby suppressing the vibration of the photovoltaic panel assembly integration 1 and the photovoltaic bracket, and reducing the damage caused to the photovoltaic panel assembly integration 1 and the photovoltaic bracket under strong wind conditions.

[0037] In addition, the present invention sets the length ratio of the row height of the photovoltaic panel assembly integration 1 to the row height of the air discharge channel 3 to 14 to 20:1, which greatly reduces the wind pressure coefficient of the photovoltaic panel assembly integration 1 and the photovoltaic bracket, and further reduces the torque of the photovoltaic panel assembly integration 1 and the photovoltaic bracket, slowing down the change of the torque of the photovoltaic panel assembly integration 1 and the photovoltaic bracket with the inclination angle, thereby further suppressing the vibration of the photovoltaic panel assembly integration 1 and the photovoltaic bracket, and reducing the damage caused to the photovoltaic panel assembly integration 1 and the photovoltaic bracket under strong wind conditions.

[0038] The present invention also provides a photovoltaic support vibration suppression method, comprising the following contents:

[0039] Complete the assembly of a photovoltaic bracket and a single photovoltaic panel assembly 1, wherein the photovoltaic panel assembly 1 includes a plurality of photovoltaic panel assemblies 2 arranged in sequence;

[0040] Complete the assembly of the photovoltaic bracket and adjacent photovoltaic panel assembly assemblies 1. The positions of the photovoltaic panel assemblies 2 in the adjacent photovoltaic panel assembly assemblies 1 correspond one to one. An air leakage channel 3 is formed between the corresponding photovoltaic panel assembly assemblies 1. The length ratio of the row height of the photovoltaic panel assembly assemblies 1 to the row height of the air leakage channel 3 is set to 14 to 20:1.

[0041] The fluid flowing from the windward side to the leeward side of the photovoltaic panel assembly integration 1, when flowing through the photovoltaic panel assembly integration 1, part of the fluid flows out from the air leakage channel 3, changing the wind pressure distribution on the windward side of the photovoltaic panel assembly integration 1, reducing the torque of the photovoltaic panel assembly integration 1, slowing down the change of the torque of the photovoltaic panel assembly integration 1 with the inclination angle of the photovoltaic panel assembly integration 1, and thus suppressing the vibration of the photovoltaic panel assembly integration 1.

[0042] To verify the principle of the present invention, a wind tunnel test was conducted on a photovoltaic bracket model 11 with and without an air leakage channel 3 (the ratio of the row height of the photovoltaic panel assembly 1 on the photovoltaic panel bracket model 11 with the air leakage channel 3 to the row height of the air leakage channel 3 was 16.7). The aerodynamic forces and torsional vibration angles of the two structures were compared, the torsion was dimensionless, and the torque was measured using the torque coefficient. The torque coefficient is defined as follows:

[0043]

[0044] Where: P wi and P ni is the upper and lower surface wind pressures at the detection point i9, U is the incoming wind speed, ρ is the air density, L i is the length represented by the detection point i9, y i is the distance between the detection point and the rotation center.

[0045] The surface wind pressure and torsion angle of photovoltaic bracket model 11 were tested. The wind tunnel test photos are as follows: Figure 6 shown.

[0046] The test results are analyzed and the test results of the two structures are as follows: Figure 7 As shown, Figure 7 is the wind pressure coefficient distribution of the detection point i9. It can be seen from the figure that there is a certain difference between the wind pressure coefficient of the windward area of ​​the photovoltaic bracket model 11 with the air leakage channel 3 and the wind pressure coefficient of the windward area of ​​the photovoltaic bracket model 11 without the air leakage channel 3. That is to say, the air leakage channel 3 has a relatively large influence on the wind pressure coefficient of the photovoltaic bracket model 11.

[0047] like Figure 8As shown, in order to further verify the test results, the torque coefficient distribution of the photovoltaic bracket model 11 with the air leakage channel 3 and the photovoltaic bracket model 11 without the air leakage channel 3 within a small inclination angle range was obtained through experiments. It can be seen from the figure that at an inclination angle of 0° (when the photovoltaic bracket model 11 is placed horizontally), the torque coefficient of the photovoltaic bracket model 11 with the air leakage channel 3 is smaller than the torque coefficient of the photovoltaic bracket model 11 without the air leakage channel 3, and the trend of change of the torque coefficient of the photovoltaic bracket model 11 with the air leakage channel 3 with the inclination angle is smoother than the trend of change of the torque coefficient of the photovoltaic bracket model 11 without the air leakage channel 3 with the inclination angle. Therefore, it can be inferred that the opening of the air leakage channel 3 on the photovoltaic bracket can suppress the vibration of the photovoltaic panel assembly integration 1.

[0048] like Figure 9 As shown, when the wind speed is 8.5 m / s, the photovoltaic bracket model 11 without the air leakage channel 3 undergoes large-scale torsional vibration, but the photovoltaic bracket model 11 with the air leakage channel 3 does not undergo large-scale torsional vibration.

[0049] In summary, it can be determined that by opening an air leakage channel 3 on the photovoltaic bracket (the ratio of the row height of the photovoltaic panel assembly integration 1 on the photovoltaic panel bracket model 11 with the air leakage channel 3 to the row height of the air leakage channel 3 is 16.7), air can pass through the air leakage channel 3, which can change the wind pressure distribution in the windward area, weaken the trend of the torque coefficient changing with the inclination angle, and thus suppress the vibration of the photovoltaic bracket and the photovoltaic panel assembly integration 1.

[0050] like Figure 3 As shown, in the present invention, the photovoltaic panel assembly integration 1 is provided with multiple mounting ears (not shown in the figure) at both ends perpendicular to the row height of the photovoltaic panel assembly integration 1, and the photovoltaic panel assembly 2 is detachably fixedly connected to the photovoltaic bracket through the mounting ears, and multiple rows of purlins 6 are provided between the mounting ears and the photovoltaic bracket, and the two ends of the purlin 6 are respectively connected to the photovoltaic panel assemblies 2 on both sides of the air discharge channel 3, and the middle part of the purlin 6 is connected to the main shaft 8, which further improves the stability of the photovoltaic panel assembly integration 1, making it less likely to fall off when rotating with the main shaft 8.

[0051] At the same time, the purlin 6 divides the air leakage channel 3 formed between the adjacent photovoltaic panel assembly integrations 1 into multiple air leakage holes, which makes the wind pressure changes on the surface of the photovoltaic panel assembly integration 1 and the photovoltaic bracket more significant, and the trend of torque changes with the inclination angle is greatly suppressed, avoiding the problem of wind-induced damage and instability of the photovoltaic panel assembly integration 1 and the photovoltaic bracket.

[0052] In the present invention, the photovoltaic panel assembly integration 1 is evenly distributed on the photovoltaic bracket, that is, the weight of the photovoltaic panel assembly 3 on the photovoltaic bracket is symmetrically distributed with the main axis 8 as the axis, which prevents the photovoltaic panel assembly integration 1 and the photovoltaic bracket from rotating due to their own gravity when they are not placed horizontally, thereby further reducing the vibration of the photovoltaic panel assembly integration 1 and the photovoltaic bracket under strong wind conditions.

[0053] In addition, if Figure 4-Figure 5 As shown, the photovoltaic panel assembly integration 1 is provided with ears 4 and bonding parts 5 on both sides perpendicular to the row height of the photovoltaic panel assembly integration 1, the photovoltaic panel assembly integration 1 on one side of the air leakage channel 3 is provided with ears 4, and the photovoltaic panel assembly integration 1 on the other side of the air leakage channel 3 is provided with bonding parts 5. An airbag 7 is provided between two adjacent groups of photovoltaic panel assembly integrations 1, and one end of the airbag 7 is fixedly connected to the adhesive portion 5, and the other end of the airbag 7 is clamped in the ear 4 after being filled with water; in windless weather conditions, when the photovoltaic panel assembly 2 needs to be cleaned, the PLC control system connected to the airbag 7 controls the corresponding water storage device to inject water into the airbag 7. After the airbag 7 is full of water, the PLC control system controls the airbag 7 to open the water spray holes arranged around the outside to clean the photovoltaic panel assembly integration 1 and remove dust on the surface of the photovoltaic panel assembly 2, so that the photovoltaic panel assembly integration 1 can maintain high efficiency; when encountering strong winds, the PLC control system controls the airbag 7 to open the outer water spray holes to quickly spray out the water inside the airbag 7, causing the airbag 7 to deflate quickly and shrink to the photovoltaic panel assembly integration 1 on the side with the adhesive portion 5, so that the air leakage channel 3 can be smoothly exposed, so as to smoothly release the wind pressure energy, suppress the vibration of the photovoltaic panel assembly integration 1 and the photovoltaic bracket, and reduce the wind-induced torsional instability damage.

[0054] In addition, a main shaft 8 is provided at the axis of the photovoltaic bracket, and the main shaft 8 is connected to the purlin 6. The main shaft 8 is connected to a driving device, which is a driving motor. The driving motor drives the main shaft 8 to drive the photovoltaic panel assembly integration 1 to rotate, thereby realizing the adjustment of the azimuth or altitude angle of the photovoltaic panel assembly integration 1.

[0055] The present invention uses specific examples to illustrate the principles and implementation methods of the present invention. The above examples are only intended to help understand the method and core concept of the present invention. At the same time, those skilled in the art will find that the specific implementation methods and application scopes may vary based on the concept of the present invention. In summary, the contents of this specification should not be construed as limiting the present invention.
