[0025] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0026] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0027] Please see Figures 1 to 6 This utility model provides a photovoltaic building integrated curtain wall, which includes:

[0028] Building Main Structure 1;

[0029] A rectangular frame 2, used for curtain wall assembly and splicing, is installed on the main building 1 through a curtain wall bracket. A slot 201 is provided in the rectangular frame 2, and a T-shaped groove 202 is provided at the top of the slot 201. A T-shaped insert plate 22 is installed on one side of the rectangular frame 2, and a T-shaped through groove 203 is provided on the other side of the rectangular frame 2 to engage with the T-shaped insert plate 22. The top of the T-shaped through groove 203 is blocked by the T-shaped groove 202 to form a limiting groove 205. A wire groove 206 is provided through the T-shaped insert plate 22.

[0030] The photovoltaic module 3 is movably inserted into the slot 201, and a side seal 4 for pressing the photovoltaic module 3 into the slot 201 is installed in the T-slot 202.

[0031] The side seal 4 includes a T-shaped sealing plate 41, which is movably inserted into a T-shaped groove 202. A recessed groove 401 is provided in the middle of the T-shaped sealing plate 41. A pressing bolt 42 for pressing the photovoltaic module 3 into the slot 201 is evenly threaded in the recessed groove 401. A limiting baffle 43 is fixedly installed on one side of the T-shaped sealing plate 41. A wire hole 403 is provided on the side of the recessed groove 401 near the limiting baffle 43. A vertical groove 402 aligned with the limiting groove 205 is provided on the T-shaped sealing plate 41. A limiting plate 44 is slidably installed in the vertical groove 402. A guide rod 45 is symmetrically installed at the bottom end of the limiting plate 44. A limiting spring 46 is sleeved on the guide rod 45. One end of the guide rod 45 away from the limiting plate 44 is inserted into the T-shaped sealing plate 41. One end of the limiting spring 46 is fixedly connected to the limiting plate 44, and the other end of the limiting spring 46 is fixedly connected to the bottom of the recessed groove 401.

[0032] It should be noted that during use, after pressing the photovoltaic module 3 into the slot 201, the adjacent rectangular frame 2 is then inserted into the T-shaped through groove 203 using the T-shaped insert plate 22. Then, the T-shaped sealing plate 41 is inserted into the T-shaped groove 202. During insertion, the limiting plate 44 is raised upwards until the vertical groove 402 is aligned with the limiting groove 205. Then, the limiting plate 44 is released, and under the pull of the limiting spring 46, the limiting plate 44 slides synchronously into the limiting groove 205 along the vertical groove 402, thus completing the limiting installation of the T-shaped sealing plate 41. Then, the sealing bolt 42 is tightened to press the photovoltaic module 3 into the slot 201. At this time, the T-shaped sealing plate 41 completes the edge sealing of the photovoltaic module 3 and also presses the adjacent rectangular frame 2 into the T-shaped through groove 203, preventing it from being pulled upwards. By splicing and installing them one by one and connecting them with the curtain wall bracket of the building body 1, the installation of the photovoltaic curtain wall can be completed. The overall assembly is very convenient.

[0033] It is worth noting that during the sealing process, the power cables of the photovoltaic module 3 are led out through the wire hole 403 and the wire groove 206, which facilitates the management of the conductive wire bundle of the photovoltaic module 3 and makes the overall wire bundle neatly arranged.

[0034] Furthermore, a mounting plate 21 for connecting with the curtain wall support of the building body 1 is installed on the back of the rectangular frame 2, which facilitates the use of bolts to fix the mounting plate 21 to the curtain wall support.

[0035] Furthermore, the top of the rectangular frame 2 is symmetrically provided with grooves 204, and the bottom of the rectangular frame 2 is symmetrically provided with protrusions 23 that engage with the grooves 204. This makes it easier for two adjacent rectangular frames 2 to engage with the grooves 204 using the protrusions 23, thereby improving the neatness of the vertical connection of the rectangular frames 2.

[0036] In the embodiments of this utility model, please refer to Figure 1 , Figure 2 and Figure 5The photovoltaic module 3 includes an outer glass layer 31 and an inner glass layer 33, with a photovoltaic cell 32 encapsulated between the outer glass layer 31 and the inner glass layer 33.

[0037] Several thermally conductive silicone strips 34 are installed on the back of the inner glass layer 33, and heat dissipation fins 35 are installed on each of the thermally conductive silicone strips 34.

[0038] It should be noted that: the outer glass layer 31 is made of ultra-clear glass to facilitate light transmission to the photovoltaic cells 32, and the inner glass layer 33 is made of coated glass. Thermal conductive silicone strips 34 and heat dissipation fins 35 are installed to dissipate heat from the entire photovoltaic module 3, improving its ventilation and heat dissipation performance, and facilitating stable power generation.

[0039] It is worth noting that when the photovoltaic cell 32 of the photovoltaic module 3 generates electricity, it is also connected to a solar photovoltaic controller via a wiring harness to control and transmit the electrical energy converted from light. The specific control principle will not be described in detail here.

[0040] In the embodiments of this utility model, please refer to Figure 1 , Figure 2 and Figure 6 An extension rod 24 is fixedly installed at each of the four corners of the back of the rectangular frame 2. A connecting frame 5 is fixedly installed on the four extension rods 24, and a decorative panel 6 is installed on the connecting frame 5.

[0041] It should be noted that: in this way, the connecting frame 5 can be used to install attractive decorative panels 6 inside the entire curtain wall to decorate the entire curtain wall and improve its aesthetics.

[0042] The working principle of the photovoltaic building integrated curtain wall provided by this utility model is as follows:

[0043] In use, after pressing the photovoltaic module 3 into the slot 201, the adjacent rectangular frame 2 is inserted into the T-shaped through groove 203 using the T-shaped insert plate 22. Then, the T-shaped sealing plate 41 is inserted into the T-shaped groove 202. During insertion, the limiting plate 44 is raised upward until the vertical groove 402 is aligned with the limiting groove 205. Then, the limiting plate 44 is released. Under the pull of the limiting spring 46, the limiting plate 44 slides into the limiting groove 205 along the vertical groove 402, thus completing the limiting installation of the T-shaped sealing plate 41. Then, the pressing bolt 42 is tightened to press the photovoltaic module 3 into the slot 201. At this time, the T-shaped sealing plate 41 completes the edge sealing of the photovoltaic module 3 and also presses the adjacent rectangular frame 2 into the T-shaped through groove 203, making it impossible to pull it out upward. By splicing and installing them one by one and connecting them with the curtain wall bracket of the building body 1, the installation of the photovoltaic curtain wall can be completed. The overall assembly is very convenient.

[0044] Furthermore, the outer glass layer 31 is made of ultra-white glass to facilitate light transmission to the photovoltaic cells 32, while the inner glass layer 33 is made of coated glass. Thermally conductive silicone strips 34 and heat dissipation fins 35 are installed to dissipate heat from the entire photovoltaic module 3, improving its ventilation and heat dissipation performance and facilitating stable power generation.

[0045] The circuits and controls involved in this utility model are all existing technologies and will not be described in detail here.

[0046] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
