Technical Field

[0001] The present invention relates to the technical field of substations, and in particular to a photovoltaic prefabricated warehouse substation. Background Art

[0002] As photovoltaic power generation technology costs decrease and efficiency improves, global installed photovoltaic capacity is growing rapidly. However, the intermittent and volatile nature of photovoltaic power generation, as well as its grid-connection requirements, pose challenges to traditional power grid architectures. Traditional substations, with their long construction cycles and limited flexibility, are ill-suited for the rapid deployment and grid connection of distributed photovoltaic power plants. Prefabricated photovoltaic substations, with their modular design and integrated boosting, protection, and monitoring functions, can effectively shorten the grid-connection cycle for new energy power plants and enhance the grid's capacity to absorb renewable energy. The core technology of prefabricated substations relies on modular design of power equipment, factory-prefabricated production, and standardized interface technologies. Recent advances in the compact design of high-voltage switchgear, transformers, and intelligent control systems have enabled the preinstallation of key equipment within containerized structures. Furthermore, the application of Building Information Modeling (BIM) and digital twin technology enables precise matching of the prefabricated structure and electrical layout with the site environment, significantly reducing on-site construction complexity.

[0011] The present invention provides a photovoltaic prefabricated warehouse substation with the following beneficial effects: 1. The photovoltaic prefabricated warehouse substation is provided with a door panel. The door panel rotates along the rotation axis to drive the fixed seat to move, the movement of the fixed seat drives the connecting rod to move, the movement of the connecting rod drives the movable top plate to move, and the movable top plate moves in and out under the limit of the limit slide rail, thereby removing the mounting plate and the quick-release assembly, thereby facilitating the installation and removal of components on the surface of the quick-release assembly. At the same time, the design of the movable top plate being located on the top of the mounting plate is conducive to reducing external impurities and rainwater to provide a certain degree of protection to the components during disassembly and subsequent maintenance, thereby improving the usability of the equipment.

[0012] 2. The photovoltaic prefabricated warehouse substation is provided with a mounting bracket. After the components are installed, the rotating shaft slides along the limit tube, and the movement of the rotating shaft drives the limit rod to move, and the movement of the rotating shaft drives the limit plate to move. When the limit plate contacts the side of the mounting plate, the mounting plate provides a lateral thrust to the limit plate to compress the first spring. When the limit rod moves to the side of the limit tube, the rotating knob is manually rotated, and the rotating knob drives the rotating shaft to rotate, and the rotating shaft drives the limit rod to rotate. The limit rod rotates into the inner wall of the positioning groove for positioning, thereby limiting the movement trajectory of the rotating shaft, thereby limiting the position of the quick-release base plate, and the guide rod guides and positions while the rotating shaft is inserted, thereby determining the vertical direction of the quick-release base plate, and after the components are installed, the gap between the mounting bracket and the quick-release base plate is conducive to heat dissipation, and at the same time, the pressure on the first spring acts in turn between the limit plate and the quick-release base plate, so that the state of the quick-release base plate remains stable, thereby stabilizing the installation state of the components, and the easy disassembly and installation process is conducive to modular classification prefabrication.

[0013] 3. The photovoltaic prefabricated warehouse substation, equipped with a drive assembly and a fixed assembly, has its bottom sunk into the ground. A tool is inserted into the side of the rotating drive block. This drives the rotating drive block to rotate, which in turn drives the fixed assembly to rotate into the ground. The top of the connecting shaft is rotatably connected to the bottom of the main box, making it easy to operate and securely install the box, thereby maintaining the stability of the substation box. Compared with traditional base installation methods, this method simplifies installation operations and provides higher stability.

[0014] 4. The photovoltaic prefabricated warehouse substation is provided with a rotating drive block, which drives the rotating drive block to rotate the reverse screw, and the rotation of the reverse screw drives the sliding rod to rotate, and the sliding rod drives the driving ring to rotate, and the driving ring drives the driving shaft to rotate through the arc driving hole, and the driving shaft drives the connecting seat to rotate, and the rotation of the connecting seat drives the fixed base to rotate, and the rotation of the fixed base drives the first threaded strip to rotate. The second spring is preset in a compressed state, and the pressure provided by the second spring pushes the threaded sleeve upward while pushing the driving ring downward. The driving ring and the sliding rod slide up and down and are stuck in the side of the driving shaft under the downward pressure provided by the second spring, thereby driving the driving shaft to rotate, the driving shaft drives the connecting seat to rotate, and the connecting seat drives the fixed base to rotate, and the connecting seat drives the first threaded strip to rotate. The rotation of the first threaded strip has the function of guiding and providing friction to the ground through the arc, so that the fixed base is easy to penetrate into the ground during rotation and takes into account the friction, thereby increasing the stability of the substation.

[0015] 5. The photovoltaic prefabricated warehouse substation is provided with a reverse screw with a thread direction opposite to the first thread strip and the second thread strip. When the substation is inserted, the fixed base rotates to drive the movable base to rotate, and the guide bracket moves downward to drive the fixed rod to penetrate the ground, thereby guiding the fixed base and the movable base. The driving ring rotates in the opposite direction, and the arc of the arc-shaped driving hole on the side of the driving ring loses its driving effect on the driving shaft, and in turn drives the driving ring to slide along the sliding rod along the arc of the arc-shaped driving hole. The threaded sleeve rises and drives the rotating ring to rise, and the rotating ring drives the guide block to slide. The sliding of the guide block supports the arc groove, and the movable seat is rotated along the fixed rotating shaft on the side of the rotating shaft seat by the force provided by the arc groove, so that the movable seat is separated, thereby increasing the pulling force on the ground and further improving the stability of the substation box.

The driving shaft 5064 drives the connecting seat 5063 to rotate. The connecting seat 5063 drives the fixed base 5061 to rotate. The connecting seat 5063 drives the first threaded strip 5062 to rotate.
