Description

Technical Field

[0001] This invention relates to the field of building materials and energy conversion, and specifically to a photovoltaic curtain wall for buildings with anti-light pollution function. Background Technology

[0002] With the global energy crisis and rising environmental awareness, solar energy, as a clean and renewable energy source, has received widespread attention. Building-integrated photovoltaic (BIPV) modules, as an important component of solar energy utilization, have been widely applied to various building surfaces, achieving an effective combination of architectural aesthetics and energy conservation and carbon reduction. However, traditional photovoltaic curtain wall designs often overlook the impact of the optical environment. Especially under direct sunlight, strong reflected light can cause visual interference and even light pollution, inconveniencing the lives of surrounding residents. Summary of the Invention

[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide a building photovoltaic curtain wall with anti-light pollution function, which solves the problem that existing photovoltaic curtain walls reflect light when exposed to sunlight, which can easily cause visual interference to the outside world and even form light pollution.

[0004] The technical solution to achieve the above objectives is: a building photovoltaic curtain wall with anti-light pollution function, installed on the building wall, comprising:

[0005] Embedded parts, which are connected to the building wall;

[0006] A fixed platform connected to the embedded part;

[0007] A connecting platform is connected to the fixed platform, the connecting platform extending outward from the fixed platform to form a cantilever end, the cantilever end being provided with a groove;

[0008] A photovoltaic curtain wall connected to the recess at the cantilever end;

[0009] An anti-reflective element connected to the groove at the cantilever end and located on the outside of the photovoltaic curtain wall.

[0010] A further improvement of the technical solution of the present invention is that: the anti-reflective component has an internal cavity;

[0011] The cavity is equipped with protective glass and a one-way mirror.

[0012] A further improvement of the technical solution of the present invention is that the one-way mirror is arranged parallel to the protective glass.

[0013] A further improvement of the technical solution of the present invention is that the embedded part includes a horizontal part connected to the fixed platform, a connecting part embedded in the building wall, and a plurality of third bolts that pass through the horizontal part and are screwed into the connecting part.

[0014] A further improvement of the technical solution of the present invention is that the third bolts are arranged at intervals.

[0015] A further improvement of the technical solution of the present invention is that: a second bolt is connected to the fixing platform, and a second through hole is provided on the fixing platform for the second bolt to pass through;

[0016] The second bolt passes through the fixing platform and is screwed into the transverse member;

[0017] The horizontal member is perpendicular to the fixed platform.

[0018] A further improvement of the technical solution of the present invention is that: a first bolt is connected to the connecting platform, and a first through hole is provided on the connecting platform for the first bolt to pass through.

[0019] A further improvement of the technical solution of the present invention is that the first bolt passes through the connecting platform and is screwed into the fixed platform.

[0020] A further improvement of the technical solution of the present invention is that the anti-reflective component is arranged parallel to the photovoltaic curtain wall.

[0021] By utilizing the above technical solution, the technical effects achieved by the present invention compared to the prior art are as follows:

[0022] This invention provides a building photovoltaic curtain wall with anti-light pollution function. The protective glass installed inside the anti-reflective component allows sunlight to shine on the photovoltaic curtain wall. Then, the one-way mirror can block the reflected light generated after the photovoltaic curtain wall is exposed to sunlight, so that the reflected light is reflected back onto the photovoltaic curtain wall, thereby further improving the photothermal conversion efficiency of the photovoltaic curtain wall.

[0023] By placing anti-reflective elements on the outside of the photovoltaic curtain wall, the anti-reflective elements can shield the photovoltaic curtain wall and protect it from damage caused by external impacts after installation.

[0024] By setting horizontal components, connecting components, and third bolts in the building walls to form embedded parts, the wall structure can be strengthened, improving the wall's load-bearing capacity and durability for equipment, and increasing the stability of the equipment on the wall. Furthermore, these embedded parts can serve as connectors between the curtain wall and the wall structure, achieving a stable connection between the curtain wall and wall components through a tight bond with concrete or other structures. This prevents the curtain wall components from swaying or tilting, eliminating the need for additional grooves in the wall during equipment installation, thus reducing installation time and improving construction efficiency.

[0033] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0034] This invention provides a building photovoltaic curtain wall with anti-light pollution function. The following is a description of the building photovoltaic curtain wall with anti-light pollution function.

[0035] See Figure 1 This invention provides a building photovoltaic curtain wall with anti-light pollution function, which is installed on a building wall A and includes: an embedded part, a photovoltaic curtain wall 1, a connecting platform 2, an anti-reflective component 3, and a fixing platform 4. The embedded part is connected to the building wall A, the fixing platform 4 is connected to the embedded part, the connecting platform 2 is connected to the fixing platform 4, and the connecting platform 2 extends outward by connecting to the fixing platform 4 to form a cantilever end. The cantilever end is provided with a groove, the photovoltaic curtain wall 1 is connected to the groove of the cantilever end, and the anti-reflective component 3 is connected to the groove of the cantilever end and is located outside the photovoltaic curtain wall 1.

[0036] Better, such as Figure 1 As shown, by placing the anti-reflective element 3 on the outside of the photovoltaic curtain wall 1, the anti-reflective element 3 can shield the photovoltaic curtain wall 1 and also protect the photovoltaic curtain wall 1, preventing it from being damaged by external impacts after installation.

[0037] Furthermore, by setting embedded parts in building wall A, the wall structure can be strengthened, improving the wall's load-bearing capacity and durability for the equipment, and increasing the stability of the equipment on the wall. These embedded parts can also serve as connectors between the curtain wall and the wall, achieving a stable connection between the curtain wall and wall components through close integration with concrete or other structures, preventing swaying or tilting of the curtain wall components. During curtain wall installation, without affecting the normal operation of the photovoltaic modules, the aesthetic appeal and technological content of the building's exterior wall are enhanced, the installation process is simplified, the system's expected lifespan is extended, and maintenance costs are reduced.

[0038] Furthermore, by setting embedded parts on the two floor slabs of the building wall A, the embedded parts set at the top and bottom can be connected to the connecting platform 2, so that the connecting platform 2 can fix the photovoltaic curtain wall 1 and the anti-reflective component 3 from the top and bottom ends, so that the position restriction of the photovoltaic curtain wall 1 and the anti-reflective component 3 by the connecting platform 2 can achieve the best effect.

[0039] See Figure 3 , Figure 4 In one specific embodiment of the present invention, the anti-reflective component 3 has a mounting cavity inside, a protective glass 31 is provided in the mounting cavity, and a one-way mirror 32 is provided in the mounting cavity. The one-way mirror 32 is arranged parallel to the protective glass 31.

[0040] Furthermore, such as Figure 3 , Figure 4As shown, the protective glass 31 is tempered glass, which can effectively resist external impacts and extend service life. The one-way mirror 32 is one-way glass. The one-way mirror 32 utilizes the semi-transparent and semi-reflective properties of light, so that half of the light coming from any side is transmitted and half is reflected, which can significantly reduce the risk of light pollution to the external environment by the photovoltaic curtain wall 1 and improve the overall visual environment of the residential area.

[0041] Furthermore, the protective glass 31 installed inside the anti-reflective component 3 allows external sunlight to shine onto the photovoltaic curtain wall 1, and the one-way mirror 32 can block the reflected light generated after the photovoltaic curtain wall 1 is exposed to sunlight, so that the reflected light is reflected back onto the photovoltaic curtain wall 1, thereby further improving the photothermal conversion efficiency of the photovoltaic curtain wall 1.

[0042] See Figure 2 , Figure 6 , Figure 7 In one specific embodiment of the present invention, the embedded part includes a transverse part 5 connected to the fixed platform 4, a connecting part 6 embedded in the building wall A, and a plurality of third bolts 7 passing through the transverse part 5 and screwed into the connecting part 6, the third bolts 7 being arranged at intervals.

[0043] Better, such as Figure 2 , Figure 6 , Figure 7 As shown, the connector 6 is installed in the building wall A so that multiple third bolts 7 can pass through the transverse member 5 and be connected to the connector 6, thereby fixing the position of the transverse member 5.

[0044] See Figure 6 In one specific embodiment of the present invention, a second bolt 42 is connected to the fixed platform 4, and a second through hole 41 is provided on the fixed platform 4 for the second bolt 42 to pass through. The second bolt 42 passes through the fixed platform 4 and is screwed into the transverse member 5. The transverse member 5 is perpendicular to the fixed platform 4.

[0045] Furthermore, such as Figure 6 As shown, the second bolt 42 passes through the fixing platform 4 and connects to the transverse member 5, so that the fixing platform 4 and the transverse member 5 are perpendicular to each other when connected, and the fixing platform 4 achieves the best fixing effect.

[0046] See Figure 1 In one specific embodiment of the present invention, a first bolt 22 is connected to the connecting platform 2, and a first through hole 21 is provided on the connecting platform 2 for the first bolt 22 to pass through. The first bolt 22 passes through the connecting platform 2 and is screwed into the fixing platform 4.

[0047] Furthermore, such as Figure 1 As shown, the first bolt 22 passes through the connecting platform 2 and connects to the fixed platform 4, so that the connecting platform 2 can be fixed in the fixed platform 4.

[0048] See Figure 2 In one specific embodiment of the present invention, the anti-reflective element 3 is arranged parallel to the photovoltaic curtain wall 1.

[0049] Furthermore, such as Figure 2 As shown, by making the anti-reflective element 3 parallel to the photovoltaic curtain wall 1, the anti-reflective element 3 can fully block the photovoltaic curtain wall 1, so that the sunlight emitted by the photovoltaic curtain wall 1 will not be projected out.

[0050] like Figures 1 to 7 As shown, the installation process of a photovoltaic curtain wall for buildings with anti-light pollution function according to the present invention will be described below.

[0051] First, a connector 6 is installed in the building wall A. Then, the horizontal component 5 is placed below the connector 6. The third bolt 7 is passed through the horizontal component 5 and connected to the connector 6, and tightened with a nut. Then, the fixing platform 4 is fixedly installed on the horizontal component 5 using the second bolt 42. Subsequently, the photovoltaic curtain wall 1 and the anti-reflective component 3 are placed in the groove on the connecting platform 2. Finally, the connecting platform 2 and the fixing platform 4 are connected using the first through hole 21, thus completing the installation.

[0052] The present invention has been described in detail above with reference to the accompanying drawings and embodiments. Those skilled in the art can make various modifications to the present invention based on the above description. Therefore, certain details in the embodiments should not be construed as limiting the present invention, and the scope of protection of the present invention shall be defined by the appended claims.
