Description

Technical Field

[0001] This utility model belongs to the field of photovoltaic power generation technology, and in particular relates to a photovoltaic module installation device for the side wall of a prefabricated box house. Background Technology

[0002] With the accelerating pace of urbanization in my country, the demand for prefabricated container houses is increasing in construction sites, temporary offices, and disaster relief and resettlement sites. Prefabricated container houses, with their simple structure, short construction period, and reusability, have become an important component of temporary building facilities. However, since these locations are mostly in environments with limited access to electricity, providing a stable and economical power source for prefabricated container houses has become a pressing issue. Currently, photovoltaic power generation, as a green, environmentally friendly, and low-carbon energy utilization method, is widely used in various types of buildings. Especially in temporary facilities, the use of solar photovoltaic modules for power supply has become an important trend. However, existing technologies for applying photovoltaic modules to prefabricated container houses have many shortcomings.

[0003] Most existing photovoltaic (PV) module support structures adopt a fixed installation method. Specifically, steel structure brackets are usually directly installed on the roof of the prefabricated container house, and PV modules are fixed by welding or bolting. While this traditional structure can meet the initial fixing requirements, it has the following major problems in practical applications: First, existing support structures are mostly welded, lacking flexibility, making disassembly, relocation, or reinstallation extremely cumbersome. Prefabricated container houses often need to be relocated frequently according to the project construction schedule, and the dismantling and reinstallation of traditional fixed PV support systems is not only time-consuming and labor-intensive, but also prone to damaging the modules, increasing maintenance and replacement costs. Second, existing installation structures have poor versatility and cannot be flexibly adjusted for different models and sizes of PV modules. With the advancement of PV technology, the size and performance parameters of PV modules are constantly being upgraded, and traditional support structures are difficult to adapt to new specifications of modules, greatly limiting their service life and adaptability. In addition, some existing support systems have not fully considered the layout of external facilities (such as air conditioning units) in their structural design, which can easily lead to spatial conflicts between the support system and external facilities after installation, affecting the overall layout and functionality. Meanwhile, due to unreasonable design of the height and strength of the supporting structure, some photovoltaic brackets pose safety hazards in strong winds or severe weather, lack stability, and are prone to damage to photovoltaic modules or building structures.
