[0029] On the basis of some of the above embodiments or embodiment one, the prefabricated base 1 is optimized and designed: the front and rear sides of the prefabricated base 1 are provided with threaded holes, and through the threaded holes and bolts, the front and rear sides of the prefabricated base 1 can be detachably fixed with a cable bridge support 7 for arranging a cable trough box 9.

[0030] Embodiment three:

[0031] On the basis of some of the above embodiments or embodiment one or embodiment two, a photovoltaic panel assembly arrangement structure based on a prefabricated block is designed, as shown in Figure 6 Fig. 7, which includes a photovoltaic panel assembly 8 and a plurality of prefabricated blocks arranged at intervals along a set direction. The front side and the rear side of each of the plurality of prefabricated blocks are detachably fixed with a support rail 3, and a plurality of photovoltaic panel assemblies 8 are supported and fixed on the two support rails 3 of the front side and the rear side of the prefabricated block along the length direction thereof. The front side of the prefabricated block located at the outermost side of the set direction is fixed with a cable bridge support 7, the top of which is detachably fixed with a cable trough box 9 arranged along the length direction of the prefabricated block, for placing the cables of the photovoltaic panel assembly 8. The rear side of the plurality of prefabricated blocks is fixed with a plurality of cable bridge supports 7 at intervals along the set direction, the top of which is fixed with a cable trough box 9 arranged along the set direction, for placing the cables of the photovoltaic panel assembly 8. The plurality of rows of prefabricated blocks are arranged left and right opposite to each other, constituting an M-shaped arrangement mode, and the adjacent two rows of prefabricated blocks form a triangular structure, which is conducive to increasing the installation area of the photovoltaic assembly and increasing the power generation. This triangular structure constitutes a closed space, effectively reducing the influence of wind load.

[0032] In summary, the prefabricated base 1 and the prefabricated support seat 2 of the prefabricated block are designed in an integrated structure, so that the structure of the entire prefabricated block is tightly and stably connected, and a solid and reliable foundation support can be provided for subsequent installation of the photovoltaic panel assembly 8, reducing the risk of photovoltaic panel shaking, displacement and other conditions caused by unstable foundation structure, and ensuring long-term stable operation of the photovoltaic system. The prefabricated support seat 2 extends upward from the front and rear sides of the prefabricated base 1. This layout can more reasonably disperse the weight and external force transmitted by the photovoltaic panel assembly 8 and related fixed components, avoiding the concentration of pressure in a certain place and causing damage to the prefabricated block or the underlying bearing surface, thereby prolonging the service life of the prefabricated block. The support rail 3 and the prefabricated support seat 2 are connected in a detachable and fixed manner, and the pressing code 4 and the support rail 3 are also detachably fixed. Such a design facilitates the installation and operation of the photovoltaic panel assembly on the construction site. The construction personnel can first place the prefabricated block in place, and then install the support rail 3, the photovoltaic panel assembly 8 and the pressing code 4 in sequence. The installation steps of each component are relatively independent and clear, which helps to improve the installation efficiency and shorten the construction period, and is especially suitable for the rapid construction of large-scale photovoltaic power stations. Since each component is detachable, if it is found during installation that the layout of the photovoltaic panel assembly 8 needs to be adjusted, such as adjusting the distance, angle, etc., it can be relatively easily achieved by detaching and re-fixing the corresponding components, thereby increasing the flexibility and adaptability of the entire photovoltaic system installation. The detachable structure design makes it more convenient for subsequent routine maintenance, fault repair and other work of the photovoltaic panel assembly. For example, when the photovoltaic panel needs to be repaired or replaced, the photovoltaic panel can be removed by detaching the pressing code 4 at the corresponding position, without the need to disassemble the entire installation structure on a large scale, thereby reducing the maintenance workload and cost. With the development of technology, if the support rail 3, the pressing code 4 and other components need to be replaced with better performance in the future, or the photovoltaic panel assembly 8 itself needs to be upgraded, the detachable connection method can easily realize the replacement of components, ensuring that the photovoltaic system can maintain good performance. By adjusting the position of the pressing code 4, different sizes and specifications of photovoltaic panel assemblies can be adapted, so that the prefabricated block has a greater application possibility in different photovoltaic projects regardless of the type of photovoltaic panel used, thereby improving the universality and application range of the prefabricated block.
