Description

Technical Field

[0001] The utility model relates to the technical field of photovoltaic bracket vibration reduction, in particular to a flexible photovoltaic bracket vibration reduction structure based on a TMD system. Background Technique

[0002] The Tuned Mass Damper (TMD) system is a vibration reduction control technology that has been widely used in engineering fields such as building structures, bridges, and high-rise buildings. This system is usually composed of a mass block, a spring, and a damper, where the spring is one of the key components connecting the mass block and the structure. By introducing a mass block and a damper into the structure, the TMD system can effectively reduce the vibration amplitude of the structure when it is subjected to external excitation, improving the stability and safety of the structure. The spring plays an important role in the TMD system, providing functions such as elastic support, storing and releasing energy, and adjusting the system frequency, thereby achieving the vibration reduction effect.

[0003] In the field of solar photovoltaics, the stability of photovoltaic modules in the flexible photovoltaic bracket structure is crucial for the installation and operation of the photovoltaic system. Traditional flexible photovoltaic bracket structures use a single cable for load-bearing or configure stabilizing cables to resist wind. Between the load-bearing single cable and the stabilizing cable, steel pipes are usually used as four-corner pyramid members at intervals. Steel pipes in the four-corner pyramid of the stabilizing cable of the flexible photovoltaic bracket have disadvantages such as excessive weight, poor elasticity, poor durability, and complex installation and maintenance. Content of the Utility Model

[0004] The utility model overcomes the deficiencies of the prior art and provides a flexible photovoltaic bracket vibration reduction structure based on a TMD system.

[0005] In order to achieve the above object, the utility model is realized by the following technical solutions.

[0006] A flexible photovoltaic bracket vibration reduction structure based on a TMD system includes a photovoltaic module and load-bearing cables. The photovoltaic module is connected to two load-bearing cables, and the two ends of the load-bearing cables are respectively connected to the bracket. It also includes four springs, a mass ball, and a stabilizing cable. The upper ends of the four springs are respectively connected to the load-bearing cables, and the lower ends of the four springs converge and are all connected to the mass ball. The four springs form a four-corner pyramid structure. The mass ball is connected to the stabilizing cable, and the two ends of the stabilizing cable are respectively connected to the bracket.

[0007] Furthermore, it also includes a steel rod. The steel rod is connected between the two load-bearing cables, and the upper ends of the four springs are respectively connected to the steel rod.

[0008] Even further, the upper ends of the four springs are evenly connected to two steel rods, and the two steel rods are both perpendicular to the two load-bearing cables.

[0009] Furthermore, a plurality of square pyramid structures are connected to the two load-bearing cables.

[0010] Furthermore, the stabilizing cable passes through the center of the mass ball and is fixedly connected to the mass ball.

[0011] The beneficial effects of the present utility model compared with the prior art are as follows:

[0012] By adding springs and mass balls to the stabilizing cable square pyramid rod structure of the present utility model, and using the spring as the stabilizing cable square pyramid of the flexible photovoltaic support, its vibration damping control effect can be utilized to suppress the vibration of the structure, enhance the stability and wind resistance performance of the structure. At the same time, the spring can be adjusted in real time according to the changes in the external environment, making the support structure more flexible and adapting to the stability requirements in different situations. Combining the TMD system with the stabilizing cable of the flexible photovoltaic support can effectively improve the stability and safety of the photovoltaic system, reduce the vibration amplitude of the structure, extend the service life of the support structure, and provide important technical support for the long-term stable operation of the photovoltaic system. The specific advantages are as follows:

[0013] (1) Reducing structural vibration: The flexible photovoltaic support is prone to vibration under the action of wind, while the TMD system can reduce structural vibration by adjusting the mass and damping, improving the stability and safety of the support.

[0014] (2) Reducing weight: The spring has a lighter weight compared to the steel rod, which can reduce the overall weight of the support, helping to reduce the load of the support and increase the installation flexibility.

[0015] (3) Reducing maintenance costs: By reducing structural vibration and extending the service life of the support, the maintenance cost and repair frequency of the support can be reduced. BRIEF DESCRIPTION OF THE DRAWINGS
