Description

Technical Field

[0001] This invention belongs to the field of housing, specifically relating to a wiring structure for the application of photovoltaic glass in housing. Background Technology

[0002] The country is now strongly advocating a low-carbon culture and promoting carbon neutrality, thus the photovoltaic power generation industry has a promising future. Existing photovoltaic glass is mainly divided into three types: monocrystalline silicon, polycrystalline silicon, and cadmium telluride. Monocrystalline silicon and polycrystalline silicon have certain limitations. The advantage of cadmium telluride over crystalline silicon power generation lies in its relatively weaker environmental impact and its greater durability; minor damage will not affect the overall power generation of the glass.

[0003] In existing photovoltaic glass power generation systems, the generated electricity is transmitted through lines that are exposed to the air and visible to the naked eye, affecting the appearance. At the same time, frequent wind and rain will accelerate the corrosion of the wires and lines, leading to damage. In addition, the exposed wiring in the photovoltaic power generation curtain wall affects the indoor appearance and aesthetics. Summary of the Invention

[0004] In order to solve the above-mentioned problems in the existing technology, the present invention aims to provide a wiring structure for photovoltaic glass applications in houses.

[0005] The technical solution adopted in this invention is as follows:

[0006] A photovoltaic glass application is used in the wiring structure of a building. The photovoltaic glass is distributed in several rows and columns on the upper layer of the building's curtain wall. The lines of the photovoltaic glass on the roof and sides of the building are concentrated in the junction box of the upper ring beam. The terminal of the line is connected to a functional compartment. The functional compartment is located on one side of the building.

[0007] Optionally, an upper and lower subframe may be provided between two adjacent photovoltaic glass units on the side of the building.

[0008] A photovoltaic connector is installed in the upper frame. The power generation adapter of the photovoltaic glass at the top of the same column is located in the upper frame and is electrically connected to the photovoltaic connector. The photovoltaic connector is connected to the line. The lines in the upper frames of several photovoltaic glasses in the same column converge on the same side and converge into the junction box.

[0009] The lower subframe is located on one side of the crossbeam, and a pressure plate is installed inside the lower subframe. The pressure plate is connected to the crossbeam by a locking device.

[0010] Optionally, adhesive strips are used to fill the gap between the two ends of the lower subframe and the crossbeam;

[0011] Structural adhesive is used to fill the space between the lower frame and the photovoltaic glass;

[0012] The side of the lower subframe away from the crossbeam is filled with sealant and foam rods.

[0013] Optionally, a thermal insulation strip is installed between two adjacent photovoltaic glass panes on the side of the building.

[0014] One end of the heat insulation strip is connected to the pressure plate by a locking device, and adhesive strips are filled between both ends of the pressure plate and different photovoltaic glass.

[0015] A cover plate is provided on the side of the pressure plate away from the heat insulation strip;

[0016] The other end of the insulation strip is connected to a column. A receiving cavity is provided on one side of the column. The lines and photovoltaic adapters in the upper frame are collected into the receiving cavity on one side of the column, and the lines in the receiving cavity on one side of the column are collected into the hub cavity.

[0017] One side of the cavity is sealed by a cable tray cover.

[0018] Alternatively, the top of the roof-mounted photovoltaic glass on the side of the house is connected to the upper ring beam, and a cable collection cavity is opened on one side of the upper ring beam, which is also sealed by a cable cover plate.

[0019] Optionally, the two photovoltaic glass panels on adjacent sides of the house are connected by a steering column. One side of the steering column has a cavity for accommodating the photovoltaic adapter and wiring. The cavity is sealed by a wiring cover plate. The steering column is snapped together with the photovoltaic glass panels on different sides of the house, and a heat insulation strip is installed between the steering column and the photovoltaic glass panels.

[0020] Optionally, the functional compartment is equipped with an energy storage device, which is a battery.

[0021] Optionally, the photovoltaic glass includes a power generation chip, a hollow area, and three panes of clear glass, with the power generation chip and the hollow area spaced apart between the three panes of clear glass.

[0022] As an option, the power generation chip is made of cadmium telluride.

[0023] Alternatively, both ends of the photovoltaic glass can be sealed with sealant.

[0024] The beneficial effects of this invention are as follows:

[0025] This invention provides a wiring structure for photovoltaic glass applications in buildings. The photovoltaic glass is distributed in several rows and columns on the upper layer of the building's curtain wall. The wiring for the photovoltaic glass on the roof and sides is centralized in a junction box within the upper ring beam. The terminals of the wiring are connected to a functional compartment located on one side of the building. This design allows for more integrated photovoltaic wiring, traceable installation, and greater convenience. The overall wiring design is concealed, enhancing the interior aesthetics.

Detailed Implementation

[0037] In this implementation, such as Figure 1 The diagram shows a photovoltaic glass application in the wiring structure of a building. The photovoltaic glass 1 is distributed in several rows and columns on the upper layer of the building's curtain wall. The lines 3 of the photovoltaic glass 1 on the roof and sides of the building are concentrated in the junction box 71 of the upper ring beam 7. The terminal of the line 3 is connected to the functional compartment 2. The functional compartment 2 is located on one side of the building.

[0038] Specifically, such as Figure 2 and Figure 3As shown, an upper subframe 4 and a lower subframe 5 are installed between two adjacent photovoltaic glass 1s in the same row on the side of the building. A photovoltaic connector 41 is installed inside the upper subframe 4. The power generation adapter 15 of the photovoltaic glass 1 located at the upper end of the same row is located inside the upper subframe 4 and is electrically connected to the photovoltaic connector 41. The photovoltaic connector 41 is connected to the line 3. The lines 3 of several photovoltaic glass 1s in the same row within the upper subframe 4 converge on the same side and converge into the junction box 71. The lower subframe 5 is installed on one side of the crossbeam 53. A pressure plate 54 is installed inside the lower subframe 5. The pressure plate 54 is connected to the crossbeam 53 by a locking member 55. Adhesive strips 52 are filled between the two ends of the lower subframe 5 and the crossbeam 53. Structural adhesive is filled between the lower subframe 5 and the photovoltaic glass 1. The side of the lower subframe 5 away from the crossbeam 53 is filled with sealant 57 and foam rods 56.

[0039] In this embodiment, all photovoltaic glass 1 in the same row are connected to photovoltaic adapter 41 through power generation adapter 15 set on the same side. The lines 3 of several photovoltaic adapters 41 in the same row and on the same side are gathered from the same side into the junction box 71 in the upper ring beam 7. All lines 3 and photovoltaic adapters 41 are hidden in the upper sub-frame 4 of the crossbeam, which can realize more integrated photovoltaic wiring, traceable installation and more convenient installation. The overall wiring design is hidden, making the interior more beautiful. Other indoor wiring can also be run in the same wiring cavity. The centralized wiring 3 facilitates unified management and distribution.

[0040] The same application of this application describes an integrated functional compartment for photovoltaic houses. In this embodiment, specifically, the functional compartment 2 includes a functional compartment outer frame, a functional compartment inner frame, a functional compartment back panel, and a functional compartment door. The functional compartment outer frame is located at both ends of the functional compartment back panel, and the end of the functional compartment outer frame away from the functional compartment back panel is connected to the wall. One side of the functional compartment outer frame is connected to one end of the functional compartment inner frame. The functional compartment inner frame and the functional compartment back panel are located on two mutually perpendicular sides of the functional compartment outer frame, and the outer side wall of the functional compartment inner frame is connected to the wall. The functional compartment door is located between the two functional compartment inner frames, and the functional compartment door is located at the end of the functional compartment inner frame away from the functional compartment back panel. The functional compartment outer frame, functional compartment inner frame, functional compartment back panel, and functional compartment door form a rectangular functional compartment receiving cavity, and an electrical control system is installed inside the functional compartment receiving cavity. By integrating the inner frame, outer frame, back panel, and door of the functional compartment into the wall, the entire functional compartment 2 is integrated with the building's photovoltaic curtain wall. The electrical control system is concealed within the functional compartments 2, which are installed inside the wall, saving interior space. This makes the functional compartment a centralized device for power distribution and line control, applicable to sunrooms and curtain walls, and equipped with both strong and weak current wells. Line 3 converges from the top of functional compartment 2 and enters the functional compartment's receiving cavity, connecting to the electrical control system within the cavity. The electrical control system includes an energy storage device, and line 3 converges at the rear of functional compartment 2 and connects to the energy storage device.

Both ends of the pressure plate 54 are filled with adhesive strips 52 between them and different photovoltaic glass 1s. A cover plate 59 is installed on the side of the pressure plate 54 away from the heat insulation strip 58. The other end of the heat insulation strip 58 is connected to a column 6. A receiving cavity is provided on one side of the column 6. The wiring 3 and photovoltaic adapter 41 in the upper frame 4 are collected into the receiving cavity on one side of the column 6. The wiring 3 in the receiving cavity on one side of the column 6 is collected into the cable management cavity 71. One side of the receiving cavity is sealed by a cable management cover plate 42. The cable management cover plate 42 is fastened to the receiving cavity and can be removed, so that it is convenient to replace or repair the photovoltaic glass 1 or the wiring 3 if there is a problem.

[0043] In this embodiment, as Figure 2 , Figure 5 and Figure 9 As shown, the top of the photovoltaic glass 1 on the side of the house is connected to the upper ring beam 7. A cable collection cavity 71 is provided on one side of the upper ring beam 7, and the cable collection cavity 71 is also sealed by the cable cover plate 42. At the same time, the top of the upper ring beam 7 is used to connect the photovoltaic glass 1 on the roof of the house, and the lines of the photovoltaic glass 1 on the roof of the house are all gathered in the cable collection cavity 71.

[0044] In this embodiment, as Figures 7-9 As shown, the photovoltaic glass 1 on the roof of the building is also distributed in several rows and columns. The photovoltaic glass 1 is installed on the main beam 9 or the secondary beam 91. Each adjacent photovoltaic glass 1 is provided with a heat insulation strip 58, a pressure plate 54, a locking piece 55, and a cover plate 59.

One end of the heat insulation strip 58 is also pressed tightly by a pressure plate 54, and then the pressure plate 54, the heat insulation strip 58, and the steering column 43 are connected together by a locking member 55.

[0046] In this embodiment, the locking element 55 is a screw or bolt assembly.

[0047] In this embodiment, to prevent the wiring plate 42 from falling off and exposing the wiring 3, a wire clamping plate 51 is provided on one side of the wiring plate 42.

[0048] In this embodiment, as Figure 10 As shown, the photovoltaic glass 1 includes a power generation chip 13, a hollow area 14, and three pieces of clear glass 12. The power generation chip 13 and the hollow area 14 are spaced apart between the three pieces of clear glass 12. The power generation chip 13 is made of cadmium telluride. During use, both ends of the photovoltaic glass 1 are sealed with sealant 57.
