Description

Technical Field

[0001] This utility model relates to the field of photovoltaic curtain walls, and more specifically, to a photovoltaic curtain wall. Background Technology

[0002] A photovoltaic (PV) curtain wall is an exterior wall structure equipped with photovoltaic panels that convert solar energy into electrical energy, providing clean energy for the building.

[0003] Traditional photovoltaic curtain walls present a contradiction between the need for shading in summer and the need for light transmission in winter; insufficient ventilation and heat dissipation in photovoltaic systems affect power generation efficiency and indoor thermal environment. To address this, a new type of photovoltaic curtain wall is proposed. Utility Model Content

[0004] The purpose of this invention is to address the contradiction between the need for summer shading and winter light transmission in traditional photovoltaic curtain walls, as well as the problem of insufficient ventilation and heat dissipation in photovoltaic systems, which affects power generation efficiency and indoor thermal environment.

[0005] To achieve the above-mentioned objectives, this utility model provides the following technical solution:

[0006] The present invention is as follows: a photovoltaic curtain wall, including a balcony body, wherein an energy-saving photovoltaic installation component is provided on the balcony body, and a ventilation component for ventilation and heat dissipation is provided on the photovoltaic installation component;

[0007] The photovoltaic installation assembly includes a balcony base fixedly installed on the balcony body, a floor-to-ceiling window installed on the balcony base, a first metal plate fixedly installed on one side of the balcony base, an inclined plate fixedly installed at the end of the first metal plate away from the balcony base, an inclined installation groove opened on the inclined plate, a photovoltaic panel installed inside the inclined installation groove, a second metal plate fixedly installed at the end of the inclined plate away from the first metal plate, and the end of the second metal plate away from the inclined plate fixedly installed at the bottom of the balcony body.

[0008] As a preferred technical solution of this utility model, the ventilation component includes ventilation holes opened at the bottom of the inclined plate. The number of ventilation holes is multiple and they are evenly distributed in a row at the bottom of the inclined plate. The inner sides of the first metal plate, the inclined plate and the second metal plate do not contact the outer wall of the balcony body to form a ventilation cavity for ventilation in conjunction with the ventilation holes.

[0009] As a preferred technical solution of this utility model, a protective net cover for preventing mosquitoes from entering the ventilation cavity is fixedly installed on the top of the ventilation hole, and the protective net cover is made of stainless steel.

[0010] As a preferred technical solution of this utility model, the surface of the photovoltaic panel is coated with a matte nano-coating to reduce glare from the photovoltaic panel.

[0011] As a preferred technical solution of this utility model, the first metal plate and the second metal plate are made of aluminum.

[0012] As a preferred technical solution of this utility model, a reinforcing plate is fixedly installed at the inner bottom of the inclined mounting groove, and the material of the reinforcing plate is stainless steel.

[0013] As a preferred technical solution of this utility model, the top of the first metal plate is provided with an inclined water guiding surface.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] 1. By setting up photovoltaic installation components, the top of the first metal plate is installed on the balcony base, and the bottom of the second metal plate is installed on the bottom of the balcony body. Then, the photovoltaic panels are installed inside the inclined installation groove, so that the photovoltaic panels are located on the wall between the floor-to-ceiling windows of the two balconies. This allows for summer sun shading: the fixed tilt angle design maximizes the blocking of high-angle sunlight and reduces the heat load of solar radiation on the balcony; and winter light transmission: the tilt angle adapts to low-angle sunlight, reducing heating shading.

[0016] 2. By setting up ventilation components, the ventilation holes and ventilation cavities can ventilate and dissipate heat from the photovoltaic panels during use. In summer, the fixed tilt angle design maximizes the blocking of high-angle sunlight, reducing the heat load of solar radiation on the balcony. The ventilation cavity layer removes the heat of the components through natural convection. In winter, the tilt angle is adapted to low-angle sunlight, reducing heating obstruction, and the cavity layer forms a static heat-insulating air layer. Attached Figure Description

[0024] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model.

[0025] Therefore, the following detailed description of the embodiments of this utility model is not intended to limit the scope of the claimed utility model, but merely to illustrate some embodiments of the utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.

[0026] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.

[0027] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0028] like Figure 1 As shown, this embodiment proposes a photovoltaic curtain wall, including a balcony body 1, an energy-saving photovoltaic installation component 2 installed on the balcony body 1, and a ventilation component 3 for ventilation and heat dissipation installed on the photovoltaic installation component 2.

[0029] like Figure 3 and Figure 6As shown, the photovoltaic mounting module 2 includes a balcony base 201 fixedly mounted on the balcony body 1. A floor-to-ceiling window 202 is installed on the balcony base 201. A first metal plate 203 is fixedly mounted on one side of the balcony base 201. An inclined plate 204 is fixedly mounted on the end of the first metal plate 203 away from the balcony base 201. An inclined mounting groove 205 is formed on the inclined plate 204. A photovoltaic panel 206 is installed inside the inclined mounting groove 205. A second metal plate 207 is fixedly mounted on the end of the inclined plate 204 away from the first metal plate 203. One end away from the inclined plate 204 is fixedly installed at the bottom of the balcony body 1. In use, the top of the first metal plate 203 is installed on the balcony base 201, and the bottom of the second metal plate 207 is installed at the bottom of the balcony body 1. Then, the photovoltaic panel 206 is installed inside the inclined mounting groove 205, so that the photovoltaic panel 206 is located on the wall between the floor windows 202 of the two adjacent balconies. This allows for summer sun shading: the fixed tilt angle design maximizes the blocking of high-angle sunlight and reduces the heat load of solar radiation on the balcony; and winter light transmission: the tilt angle adapts to low-angle sunlight, reducing heating obstruction.

[0030] like Figure 3 and Figure 6 As shown, the bottom of the inclined plate 204 is provided with ventilation holes 301. There are multiple ventilation holes 301, which are evenly distributed in a row at the bottom of the inclined plate 204. The inner sides of the first metal plate 203, the inclined plate 204 and the second metal plate 207 do not contact the outer wall of the balcony body 1 to form a ventilation cavity 302 for ventilation in conjunction with the ventilation holes 301. When in use, the ventilation holes 301 and the ventilation cavity 302 can ventilate and dissipate heat for the photovoltaic panel 206. In summer, the fixed tilt angle design maximizes the blocking of high-angle sunlight and reduces the heat load of solar radiation on the balcony. The ventilation cavity 302 layer removes the heat of the component through natural convection. In winter, the tilt angle is adapted to low-angle sunlight, reducing heating shading. The cavity layer forms a static heat-insulating air layer.

[0031] like Figure 3 and Figure 6 As shown, a protective net cover 4 for preventing mosquitoes from entering the ventilation cavity 302 is fixedly installed on the top of the ventilation hole 301. The protective net cover 4 is made of stainless steel and can prevent mosquitoes from entering the ventilation cavity 302 when in use.

[0032] like Figure 6 As shown, the surface of the photovoltaic panel 206 is coated with a matte nano-coating 5 to reduce the glare of the photovoltaic panel 206. When in use, the matte nano-coating 5 can reduce the glare of the photovoltaic panel 206.

[0033] like Figure 3As shown, the first metal plate 203 and the second metal plate 207 are made of aluminum. When in use, the photovoltaic panel 206 is arranged in combination with the aluminum plate. The matte coating and parametric arrangement weaken the industrial feel of the photovoltaic panel 206 and achieve geometric coordination with the building facade.

[0034] like Figure 6 As shown, multiple reinforcing plates 6 are fixedly installed on the inner bottom of the inclined mounting groove 205. All reinforcing plates 6 are parallel to each other and spaced apart. The material of the reinforcing plates 6 is stainless steel. When in use, the reinforcing plates 6 can reinforce the installed photovoltaic panel 206 and improve the installation effect of the photovoltaic panel 206.

[0035] like Figure 5 As shown, the top of the first metal plate 203 is provided with an inclined water guiding surface 7. When in use, the inclined water guiding surface 7 can guide the water dripping onto the first metal plate 203 and prevent water stains from accumulating on the first metal plate 203.

[0036] Specifically, in use, this photovoltaic curtain wall is installed as follows: the top of the first metal plate 203 is installed on the balcony base 201, the bottom of the second metal plate 207 is installed on the bottom of the balcony body 1, and then the photovoltaic panel 206 is installed inside the inclined mounting groove 205, so that the photovoltaic panel 206 is located on the wall between the two balconies' floor-to-ceiling windows 202. This achieves the following: summer sun shading, the fixed tilt angle design maximizes the blocking of high-angle sunlight, reducing the heat load of solar radiation on the balcony, and the ventilation cavity 302 layer removes heat from the components through natural convection; winter light transmission: the tilt angle adapts to low-angle sunlight, reducing heating shading, and the cavity layer forms a static heat-insulating air layer; visual integration: the photovoltaic panel 206 is combined with the aluminum plate, and the matte nano-coating 5 and parametric arrangement weaken the industrial feel of the photovoltaic panel 206, achieving geometric coordination with the building facade. Through fixed tilt angle optimization, thermal design of ventilation cavity 302, and matte coating technology, the problems of poor seasonal adaptability, single energy efficiency, and visual abruptness of traditional BIPV systems are solved (e.g., Figure 6 (As shown).

[0037] All technical features in this embodiment can be freely combined according to actual needs.

[0038] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
