Description

Technical Field

[0001] The utility model relates to the technical field of photovoltaic buildings, in particular to an integrated prefabricated exterior wall of a photovoltaic building. Background Art

[0002] Solar photovoltaic buildings are a new concept in the application of solar power generation. They are the perfect combination of solar photovoltaic systems and modern buildings. Photovoltaic modules are laid on the outer surface of the building structure to provide electricity. The solar power generation system is integrated with the roof, skylight, curtain wall and other buildings to build green and environmentally friendly houses. Photovoltaic building integration is a key technology to solve the electricity demand of energy-saving buildings. The existing photovoltaic building integration mainly installs photovoltaic arrays on the exterior walls and roofs.

[0003] Most existing photovoltaic panel assemblies are fixed to the exterior wall of a building using bolts and clamps. When installing photovoltaic panels, the bolts will be nailed into the exterior wall of the building. The surface of the exterior wall has waterproof and heat-insulating coatings. After the bolts are driven in, the structure of the exterior wall will be destroyed, affecting the use effect of the exterior wall.

[0004] At the same time, the existing prefabricated walls are in contact with the main beams separately after installation, the splicing effect is poor, and position displacement is prone to occur. The photovoltaic modules will increase the force on the exterior wall, causing the photovoltaic modules and the exterior wall to easily fall off, affecting the installation effect of the photovoltaic panels. Moreover, the photovoltaic modules are mostly installed by relying only on clamps for fixation, and the contact area with them is small. After long-term fixation, the photovoltaic modules will fall off due to fewer force points, which will also affect the use of the photovoltaic panels. Utility Model Content

[0022] See also Figure 1-4As shown, a photovoltaic building integrated prefabricated exterior wall comprises an exterior wall panel 1, which is used to be installed on the exterior wall surface of a building. A connecting shell 2 is fixedly connected to one side of the exterior wall panel 1 at both the upper and lower positions. The connecting shell 2 is of U-shaped design. The exterior wall panel 1 and the connecting shell 2 are made of the same material. A positioning rod 3 is slidably connected to the inner cavity of the connecting shell 2. One side of the positioning rod 3 is slidably connected to the surface of the exterior wall panel 1. The positioning rod 3 can be inserted into the interior of another prefabricated exterior wall connecting shell 2, so that the two prefabricated exterior walls can be spliced, so that the prefabricated exterior wall has better stability after installation. A through groove 4 is provided on the top of the connecting shell 2. A toggle rod 5 is slidably connected to the inner cavity of the through groove 4. The bottom of the toggle rod 5 is fixedly connected to the top of the positioning rod 3. When the position of the positioning rod 3 needs to be moved, it can be moved by toggle The movable rod 5 drives the positioning rod 3 to move, thereby providing an effective force application point for the staff when moving the positioning rod 3, making it more convenient for the positioning rod 3 to move. The length of the inner cavity of the through groove 4 is greater than half of the length of the positioning rod 3. The through groove 4 is used in conjunction with the positioning rod 3. Under this action, the toggle rod 5 can be blocked, thereby limiting the positioning rod 3, so that the distance when it moves to the inside of another prefabricated exterior wall connecting shell 2 is not less than half of its own length, which can effectively improve the stability of the two prefabricated exterior walls after being connected, and can also prevent the positioning rod 3 from being broken due to more force on one side. The cross-sectional shape of the toggle rod 5 is T-shaped, and the diameter of the top of the toggle rod 5 is greater than the width of the inner cavity of the through groove 4. Under this action, it is not only convenient for the staff to push the positioning The fixing bolt 7 is provided on one side of the connecting shell 2, and the fixing bolt 7 is provided on the other side of the connecting shell 2. The fixing bolt 7 is provided on the one side of the connecting shell 2, and the fixing bolt 7 is provided on the one side of the connecting shell 2. The fixing bolt 7 is provided on the fixing bracket 6 and the fixing bracket 6 and the fixing bracket 3, so that the fixing bracket 6 and the fixing bracket 3 are not easily moved when the fixing bracket 3 is moved to the inside of another prefabricated exterior wall connecting shell 2, and the stability of the prefabricated exterior wall is effectively improved. A photovoltaic panel 13 is provided on one side of the fixing bracket 6, so that when the staff installs the photovoltaic panel 13, the clamp can be fixed on the surface of the fixing bracket 6, so that the photovoltaic panel 13 will not cause damage to the exterior wall panel 1 when it is fixed, and the situation that the exterior wall panel 1 is broken and its performance is reduced is avoided. Under the action of the frame 6, a certain space can be created between the photovoltaic panel 13 and the exterior wall panel 1, thereby preventing the heat of the photovoltaic panel 13 from being directly conducted to the inside of the exterior wall panel 1, effectively improving the performance of the exterior wall panel 1 itself, and a connecting plate 8 is fixed to the bottom of the lower connecting shell 2, and a positioning shell 9 is fixed to one side of the connecting plate 8, and the top of the positioning shell 9 is movably connected to the bottom of the photovoltaic panel 13, under this action, the photovoltaic panel 13 can be supported, making it more stable during installation, and the stability of the photovoltaic panel 13 after installation can also be improved, reducing the situation where the photovoltaic panel 13 is offset in position, and the inner cavity of the positioning shell 9 is slidably connected with a movable plate 10, which is used to block the photovoltaic panel 13, thereby fixing it for a second time to prevent it from moving easily,The stability of the photovoltaic panel 13 is effectively improved. Both sides of the inner cavity of the positioning shell 9 are provided with connection grooves 11. The inner cavity of the connection groove 11 is slidably connected with a positioning block 12. One side of the positioning block 12 is fixedly connected to the movable panel 10. Under this action, the movable panel 10 can be clamped inside the positioning shell 9 under the cooperation of its own weight to prevent it from moving easily. Moreover, when installing the photovoltaic panel 13, the movable panel 10 can be disassembled and then used to fix it again after installation. The bottom of the movable panel 10 is lower than the bottom of the exterior wall panel 1. The distance from the top of the movable panel 10 to the top of the positioning shell 9 is the same as the distance from the bottom of the movable panel 10 to the bottom of the positioning shell 9. Under this action, the movable panel 10 can also fix the photovoltaic panel 13 located on the prefabricated exterior wall below, thereby effectively improving the applicability of the prefabricated exterior wall.

The specific structure, working principle, and possible control method and spatial layout method of these technical features can be selected according to conventional methods in the field, and this technical solution will not be further elaborated.

[0024] Working principle: First, the exterior wall panel 1 is installed on the main beam of the building, and then another prefabricated exterior wall is installed on one side thereof. Then, the staff pushes the positioning rod 3 to move in the inner cavity of the connecting shell 2 by using the toggle rod 5, so that the positioning rod 3 can move to the inside of the connecting shell 2 of the prefabricated exterior wall on the other side, thereby connecting the two prefabricated exterior walls and improving their stability after installation. Then, the mounting frame 6 is placed on one side of the connecting shell 2, and the mounting frame 6 and the positioning rod 3 are fixed with the fastening bolts 7 so that they will not move easily. Then, the movable plate 10 is taken out, and then the photovoltaic panel 13 is placed on the top of the positioning shell 9, and then the photovoltaic panel 13 is fixed to the surface of the mounting frame 6 with a clamp, and then the movable plate 10 is inserted into the interior of the positioning shell 9. With the cooperation of the connecting groove 11 and the positioning block 12, the movable plate 10 can be limited so that it will not move easily, and under the action of the movable plate 10, the top of the photovoltaic panel 13 in the prefabricated exterior wall below can also be clamped, which effectively improves the stability of the photovoltaic panel 13 and increases the applicability of the prefabricated exterior wall.
