TECHNICAL FIELD
[0001] The utility model relates to photovoltaic module installation accessory technical field especially relates to a photovoltaic trough fixing device. BACKGROUND
[0002] In the field of photovoltaic power generation today, photovoltaic trough fixing device plays a vital role in ensuring the stable operation of photovoltaic system. With the rapid development of photovoltaic power generation industry, photovoltaic trough is widely used in the cooling of photovoltaic panel, rainwater collection and other aspects to improve the power generation efficiency and service life of photovoltaic system. However, how to stably and reliably fix the trough near the photovoltaic panel has been one of the key research directions in this field. A photovoltaic trough fixing device with excellent performance not only needs to adapt to different installation environments and photovoltaic panel layouts, but also needs to ensure the stability of the trough under various complex natural conditions to prevent the normal operation of the entire photovoltaic system from being affected by problems such as loosening.
[0003] At present, in the photovoltaic trough fixing technology, the traditional method mainly connects the trough and the support structure of the photovoltaic panel through a simple bolt connection method. The technical principle of this connection method is to use the fastening force of the bolt to tightly adhere the trough and the support part together, and rely on the friction force between the parts to maintain the fixed state. In some relatively simple designs, holes are punched on the support structure, then ordinary bolts are passed through the corresponding hole positions of the trough and the support structure, and the nuts are tightened to achieve the fixation of the trough. This mechanical structure is relatively simple and convenient to install without complex tools and operation processes.
[0004] However, this traditional fixing method has a more prominent problem. Since photovoltaic equipment is usually installed outdoors, it will be continuously affected by various external forces such as wind, vibration, etc. Under the influence of long-term wind and sun and frequent vibration, the bolt fixing the trough is prone to loosening. Once the bolt is loose, the connection between the trough and the support structure will become unstable, and when the trough shakes or is affected by external forces, the drain trough is prone to displacement or even falling off. This not only affects the auxiliary functions of the trough on the photovoltaic panel, such as cooling effect and rainwater collection efficiency, but also may cause physical damage to the photovoltaic panel due to the shaking of the trough, thereby reducing the power generation efficiency and stability of the entire photovoltaic system, increasing the maintenance cost and safety hazards.
