Description

Technical Field

[0001] This invention relates to the field of coal yard construction technology, and more specifically to a building-integrated photovoltaic (BIPV) device. Background Technology

[0002] According to national environmental protection requirements, newly built and existing coal yards must be enclosed and renovated to prevent coal from being damaged and polluted by severe weather. The height of the coal pile and the operation requirements of the bucket wheel excavator determine that the canopy of the newly built and renovated canopy must adopt an ultra-large span column-free space structure. The large span steel structure grid structure can just meet the needs of the coal yard enclosure renovation.

[0003] Space frames, as a type of highly statically indeterminate spatial truss structure, are widely used in industrial and civil construction due to their high stiffness, integrity, good seismic performance, economy, safety, and ease of fabrication and installation. A space frame is a grid structure formed by the interconnection of multiple arc-shaped trusses. The arc-shaped trusses at both ends of the space frame are connected to supports, which secure the space frame to the ground.

[0004] Combination Figure 8 As shown, when the space frame is subjected to an external impact force F, it generates a huge horizontal outward thrust F2 and a vertical downward force F3 on the supports at both ends of the space frame. The vertical downward force F3 has a relatively small impact on the space frame, so a foundation and ground beams are required. The ground beams are connected to the supports so that they can withstand the horizontal outward thrust F2 on the space frame, thus protecting it. This method requires the ground beams to have very high rigidity, which increases the cost of building construction. Furthermore, when the space frame is subjected to disasters such as earthquakes, the horizontal thrust becomes more complex under seismic action. Even with high rigidity, the ground beams may not be able to withstand the forces generated by earthquakes, causing the supports to fail to provide effective support for the space frame, easily damaging it, causing economic losses, and affecting personal safety. Summary of the Invention

[0005] In view of this, the present invention provides a building-integrated photovoltaic (BIPV) device to address the problem that when a grid structure is subjected to an external impact force F, it generates a large horizontal outward thrust F2 and a vertical downward force F3 on the supports at both ends of the grid structure. The vertical downward force F3 has a relatively small impact on the grid structure, thus requiring a foundation and ground beams. The ground beams, connected to the supports, can withstand the horizontal outward thrust F2, thus protecting the grid structure. This method requires very high rigidity in the ground beams, increasing the cost of construction. Furthermore, when the grid structure is subjected to disasters such as earthquakes, the horizontal thrust becomes more complex under seismic action. Even with high rigidity, the ground beams may not be able to withstand the forces generated by earthquakes, resulting in the supports failing to provide effective support for the grid structure, easily damaging it, causing economic losses, and affecting personal safety.

[0006] This invention provides a building-integrated photovoltaic (BIPV) device, comprising:

[0007] The space frame is designed to be curved.

[0008] A reinforcing unit is disposed within the arc-shaped opening. Both ends of the reinforcing unit are connected to the grid frame to support the opening. The reinforcing unit is configured as a photovoltaic panel.

[0009] At least two first suspension lines are provided and located at both ends of the reinforcing unit. One end of the first suspension line is connected to the reinforcing unit, and the other end of the first suspension line is connected to the space frame.

[0010] Beneficial effects: By incorporating reinforcing units (photovoltaic panels) and a first suspension line, the photovoltaic panels support the openings in the grid structure, enhancing its load-bearing capacity. This transforms the horizontal outward thrust on the grid structure into the internal force of the first suspension line. This eliminates the need for increased rigidity of the ground beams and the complexity of the connection between the ground beams and supports, reducing the cost of improving the load-bearing capacity of the grid structure. Furthermore, the reinforcing units, located within the openings of the grid structure, improve space utilization and can also absorb sunlight for power generation, achieving two benefits and further reducing the manufacturing cost of integrated building-integrated photovoltaic (BIPV) systems.

[0011] In one optional embodiment, the grid structure includes bolt balls and fixing units, with multiple bolt balls and fixing units provided, and adjacent fixing units connected by the bolt balls; the building-integrated photovoltaic device includes:

[0012] The first connecting structure has one end connected to the bolt ball, and the other end of the first connecting structure has a first through hole for passing through the first suspension wire, and the first suspension wire is connected to the first connecting structure.

[0013] Beneficial effects: Since multiple fixing units are already connected to the bolt ball, the remaining installation space for the bolt ball is relatively small. By setting up a first connecting structure, which can be directly connected to the bolt ball and also connected to the first suspension line, the installation space between the bolt ball and the first suspension line is increased. This simplifies the connection between the bolt ball and the reinforcing unit, thereby improving the ease of manufacturing and reliability of the building-integrated photovoltaic device.

[0014] In one optional embodiment, the first connecting structure has a mounting groove on the side near the bolt ball, the mounting groove communicating with the first through hole, the mounting groove being used to accommodate the bolt ball and to accommodate one end of the first suspension wire;

[0015] And / or, the radial dimension of the first through hole is greater than the radial dimension of the first suspension wire;

[0016] And / or, the building-integrated photovoltaic (BIPV) device includes:

[0017] An intermediate structure is provided between the space frame and the reinforcing unit. The intermediate structure has a second through hole for passing through the other end of the first suspension wire and connecting it to the first suspension wire. The intermediate structure is connected to the reinforcing unit.

[0018] And / or, a first limiting unit is disposed in the mounting groove and connected to the first connecting structure. The first limiting unit includes a first limiting structure and a second limiting structure. The first limiting structure and the second limiting structure are spaced apart. The space is used to accommodate one end of the first suspension line so as to limit the position of the first suspension line.

[0019] Beneficial effects: By adapting the first connecting structure to the shape of the bolt ball, the connection area between the first connecting structure and the bolt ball is increased, thereby achieving the technical effect of improving the connection reliability between the first connecting structure and the bolt ball;

[0020] By ensuring that the radial dimensions of both the first and second through holes are larger than the radial dimension of the first suspension wire, the position of the first suspension wire passing through the first and second through holes can be adjusted according to the connection position between the bolt ball and the reinforcing unit, i.e., the tilt angle of the first suspension wire can be adjusted. This achieves the technical effect of improving the reliability of the connection between the space frame and the intermediate structure.

[0021] By setting an intermediate structure, it can serve as a transfer connection point between the space frame and the reinforcement unit, thereby improving the connection rigidity between the space frame and the reinforcement unit. This allows the first suspension line between the space frame and the reinforcement unit to absorb impact force and ensure the reliability of the connection between the space frame and the reinforcement unit.

[0022] By setting a first limiting unit, which includes a first limiting structure and a second limiting structure spaced apart, one end of the first suspension line can be initially limited, allowing the one end of the first suspension line to move within the interval between the first limiting structure and the second limiting structure. This also improves the stability of the position of the first suspension line when it tilts with the tilt between the bolt ball and the reinforcing unit, thereby achieving the technical effect of improving the reliability of the connection between the bolt ball and the reinforcing unit.

[0023] In one optional embodiment, the first through hole and / or the second through hole is an oblong hole;

[0024] And / or, the intermediate structure is provided with a third through hole, and the building-integrated photovoltaic device includes:

[0025] The second suspension line is connected at both ends to the intermediate structures at both ends of the reinforcing unit, and is used to support the reinforcing unit.

[0026] Beneficial effects: By setting a second suspension line, the length of the suspension line used in the building-integrated photovoltaic (BIPV) device can be increased, so that when the reinforcement unit is subjected to impact force, it can be converted into the internal force of the second suspension line, reducing the possibility of the impact force being transmitted to the grid structure, thereby achieving the technical effect of improving the structural stability of the BIPV device.

[0027] In one optional embodiment, the building-integrated photovoltaic (BIPV) device includes:

[0028] A first positioning structure is disposed in the mounting groove. The first positioning structure includes a first channel for accommodating one end of the first suspension wire. The radial dimension of the first channel is larger than the radial dimension of the first through hole. The first positioning structure is used to fix one end of the first suspension wire in the mounting groove to connect the first suspension wire and the bolt ball.

[0029] And / or, a second positioning structure, including a second channel for receiving the other end of the first suspension wire, the radial dimension of the second channel being greater than the radial dimension of the second through hole, for connecting the other end of the first suspension wire to the intermediate structure;

[0030] And / or, a third positioning structure, including a third channel, the third channel being used to receive one end of the second suspension wire and / or the other end of the second suspension wire, the radial dimension of the third channel being greater than the radial dimension of the third through hole, for connecting one end of the second suspension wire to the intermediate structure and the other end of the second suspension wire to the intermediate structure;

[0031] And / or, a second limiting unit is disposed on the side of the intermediate structure away from the first connecting structure and connected to the intermediate structure. The second limiting unit includes a third limiting structure and a fourth limiting structure. The third limiting structure and the fourth limiting structure are spaced apart and disposed at both ends of the second through hole. The space is used to accommodate the other end of the first suspension wire so as to limit the position of the first suspension wire through the space.

[0032] And / or, a third limiting unit is provided on the side of the intermediate structure near the first connecting structure and at both ends of the second suspension line, and is connected to the intermediate structure. The third limiting unit includes a fifth limiting structure and a sixth limiting structure, which are spaced apart and provided at both ends of the third through hole. The gap is used to accommodate the second suspension line.

[0033] Beneficial effects: By setting the first positioning structure, the first limiting unit can act as a knot for the first suspension line, fixing one end of the first suspension line in the mounting groove without detaching from the mounting groove, thereby improving the technical effect of improving the position reliability of the first suspension line, so as to achieve a stable connection between one end of the first suspension line and the first connecting structure, thereby improving the technical effect of improving the reliability of the building photovoltaic integrated device.

[0034] The second positioning structure can achieve the technical effect of improving the reliability of the other end of the first suspension wire being placed on one side of the intermediate structure. Two third positioning structures are provided: one at one end of the second suspension wire and the other at the other end, to define the positions of both ends of the second suspension wire and the third through hole, and to improve the reliability of the second suspension wire being placed on one side of the intermediate structure, thereby improving the reliability of the building-integrated photovoltaic (BIPV) device.

[0035] The second limiting unit can improve the stability of the other end of the first suspension line. The third limiting unit is located at both ends of the second suspension line, that is, there are two third limiting units. One third limiting unit is connected to one end of the second suspension line, and the other third limiting unit is connected to the other end of the second suspension line. The technical effect of improving the reliability and stability of the positions at both ends of the second suspension line can be achieved through the third limiting unit.

[0036] In one optional embodiment, the first limiting unit is provided with a first arc groove, and / or the second limiting unit is provided with a second arc groove, the building-integrated photovoltaic device comprising:

[0037] A first rotating structure is disposed on the first limiting unit and / or the second limiting unit, and disposed within the first arc groove and / or the second arc groove. The shape of the first rotating structure is configured to match the first arc groove and / or the second arc groove. The first rotating structure is provided with a first fixing groove having the same radial dimension as the first suspension line, so as to adjust the position of the first rotating structure within the first arc groove and / or the second arc groove according to the tilt angle during the installation of the first suspension line, so that the first fixing groove can be disposed on the extension path of the first suspension line.

[0038] And / or, the third limiting unit is provided with a third arc groove, and the building-integrated photovoltaic device includes:

[0039] A second rotating structure is disposed within the third arc groove, and the shape of the second rotating structure is configured to fit the third arc groove. The second rotating structure is provided with a second fixing groove having the same radial dimension as the second suspension wire. The second fixing groove is used to accommodate one end or the other end of the second suspension wire. The second rotating structure is used to rotate within the third arc groove according to the installation direction of the second suspension wire, so as to adjust the position of the second rotating structure within the third arc groove according to the tilt angle during the installation of the second suspension wire, so that the second fixing groove can be disposed on the extension path of the second suspension wire.

[0040] Beneficial effects: By setting a first rotating structure, when the first rotating structure is not connected to the first limiting unit, it can rotate within the first or second arcuate groove along with the first suspension line. Then, one of the first rotating structures is fixed to the inner wall of the first arcuate groove, and the other is fixed to the inner wall of the second arcuate groove, for example, by welding. Based on this, the first fixing groove can be positioned in the extension direction of the first suspension line, improving the positional stability and reliability of the first suspension line.

[0041] The first and second rotating structures have the same specific structure. Similarly, by setting the second rotating structure, when the second rotating structure is not connected to the second limiting unit, the second rotating structure can rotate within the third arc groove as the second suspension line tilts. Then, the second rotating structure is fixed to the inner wall of the third arc groove, for example, by welding. Based on this, the technical effect of improving the positional reliability of the second suspension line can be achieved.

[0042] In one optional embodiment, both the first limiting structure and the second limiting structure are provided with the first arc groove, and the first rotating structure includes:

[0043] A first rotating component is disposed within the first arc groove of the first limiting structure, and the shape of the first rotating component is the same as the shape of the first arc groove.

[0044] The second rotating component is disposed in the first arc groove of the second limiting structure, and the shape of the second rotating component is the same as the shape of the first arc groove.

[0045] The second connecting structure is provided with the first fixing groove. The second connecting structure is connected to the side of the first rotating member that is closer to the first positioning structure. The second connecting structure is also connected to the side of the second rotating member that is closer to the first positioning structure.

[0046] Beneficial effects: By setting a first rotating component, a second rotating component, and a second connecting structure, the second connecting structure can connect the first rotating component and the second rotating component, thereby increasing the technical effect of the positional reliability of the first rotating component and the second rotating component. At the same time, the second connecting structure can also limit the position of the first suspension line, thereby achieving the technical effect of improving the positional reliability of the first suspension line.

[0047] In one optional embodiment, the building-integrated photovoltaic (BIPV) device includes:

[0048] A shock-absorbing unit is disposed between the first positioning structure and the first rotating structure and / or between the second positioning structure and the first rotating structure and / or between the third positioning structure and the second rotating structure; the shock-absorbing unit includes a fourth channel for threading the first suspension wire or the second suspension wire.

[0049] Beneficial effects: By setting up vibration damping units, vibration damping can be achieved, reducing the impact of wind load and seismic load on building photovoltaic integrated devices, thereby improving the technical effect of improving the reliability of building photovoltaic integrated devices.

[0050] In one alternative implementation, the damping unit is a spring.

[0051] Beneficial effects: By limiting the damping unit to a spring, which is readily available, the technical effect of improving the ease of manufacturing of building photovoltaic integrated devices is achieved.

[0052] In one alternative implementation, the reinforcing unit extends in a direction parallel to the extension direction of the connecting lines at both ends of the space frame.

[0053] Beneficial effects: By limiting the extension direction of the reinforcing unit to be parallel to the extension direction of the connecting lines at both ends of the grid, the extension direction of the reinforcing unit can be easily determined, thereby improving the ease of installation of photovoltaic panels and the grid.

[0073] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0074] The following is combined with Figures 1 to 8 The following describes embodiments of the present invention.

[0075] According to an embodiment of the present invention, a building-integrated photovoltaic (BIPV) device is provided, comprising:

[0076] Space frame 1 is designed to be curved;

[0077] The reinforcing unit 2 is located inside the arc-shaped opening 101. Both ends of the reinforcing unit 2 are connected to the grid frame 1 to support the opening 101. The reinforcing unit 2 is a photovoltaic panel.

[0078] At least two first suspension lines 3 are provided and are located at both ends of the reinforcing unit 2. One end of the first suspension line 3 is connected to the reinforcing unit 2, and the other end of the first suspension line 3 is connected to the space frame 1.

[0079] In the building-integrated photovoltaic (BIPV) device of this embodiment, by setting up a reinforcing unit 2 and a first suspension line 3, the reinforcing unit 2 is a photovoltaic panel, which supports the opening 101 of the grid frame 1, thereby improving the load-bearing capacity of the grid frame 1. This transforms the horizontal outward thrust on the grid frame 1 into the cable internal force of the first suspension line 3. This eliminates the need for increasing the rigidity of the ground beam and the complexity of the connection between the ground beam and the support, as required in related technologies, thus reducing the cost required to improve the load-bearing capacity of the grid frame 1. Simultaneously, the reinforcing unit 2, located within the opening 101 of the grid frame 1, achieves the technical effect of improving the space utilization of the grid frame 1. Furthermore, the reinforcing unit 2 can absorb sunlight to generate electricity, achieving two benefits at once, thereby reducing the manufacturing cost of the building-integrated photovoltaic device.

[0080] Specifically, in combination Figure 8 As shown, when the space frame 1 is subjected to an external impact force F, the impact force F is decomposed into a horizontal force F2 and a vertically downward force F3, where F2 = F * cosα and F3 = F * sinα, and α is the direction of the impact force F. Figure 8 The angle between the horizontal forces F2. Among them, the vertically downward force F3 has a relatively small impact on the impact damage of the grid frame 1. F2 is converted into F1 through the first suspension line 3. F1 and F2 are the same in magnitude but opposite in direction. That is, the first suspension line 3 at both ends of the reinforcing unit 2 will generate two F1 in opposite directions. The F1 on both sides is converted into internal forces of the cable and cancels each other out, so that the horizontal force will not damage the reinforcing unit 2 and the grid frame 1, thereby achieving the technical effect of improving the load resistance performance of the building photovoltaic integrated device.

[0081] Of course, in other embodiments, the shape of the grid frame 1 is adjusted according to the different designs of the building-integrated photovoltaic device.

[0082] In addition, in this embodiment, a plurality of first suspension wires 3 are provided between one end of the reinforcing unit 2 and the space frame 1, and a plurality of first suspension wires 3 are provided between the other end of the reinforcing unit 2 and the space frame 1, so as to increase the number of connection points between the reinforcing unit 2 and the space frame 1, thereby achieving the technical effect of improving the connection reliability between the reinforcing unit 2 and the first suspension wires 3.

[0083] As an alternative implementation, one end of the reinforcing unit 2 may be connected to the space frame 1 by a first suspension wire 3, and the other end of the reinforcing unit 2 may also be connected to the space frame 1 by a first suspension wire 3. Alternatively, one end of the reinforcing unit 2 may be connected to the space frame 1 by multiple first suspension wires 3, and the other end of the reinforcing unit 2 may also be connected to the space frame 1 by a first suspension wire 3. Or, one end of the reinforcing unit 2 may be connected to the space frame 1 by a first suspension wire 3, and the other end of the reinforcing unit 2 may also be connected to the space frame 1 by multiple first suspension wires 3.

[0084] In addition, combined Figure 1As shown, in this embodiment, multiple reinforcing units 2 are provided, that is, multiple units are provided along both the X-axis and Y-axis directions. Adjacent reinforcing units 2 are connected along the direction parallel to the Y-axis. Among the multiple reinforcing units 2, the reinforcing unit 2 closest to the space frame 1 along the direction parallel to the Y-axis is connected to the space frame 1 via a first suspension wire 3. The reinforcing unit 2 along... Figure 1 The dimension along the X-axis is smaller than that of the adjacent bolt balls 102 in space frame 1. Figure 1 The dimension along the X-axis. Based on this, according to the arc-shaped opening 101 of each space frame 1 along... Figure 1 The dimensions in the X-axis and Y-axis directions are different. Adjusting the number of reinforcing units 2 improves the adaptability to different sizes of building-integrated photovoltaic (BIPV) devices. Adjacent reinforcing units 2 along the X-axis direction may or may not be connected, both of which are within the scope of protection of this invention.

[0085] Of course, in other embodiments, the number of reinforcement units 2 may be adjusted according to the different designs of the building photovoltaic integrated device, for example, only one unit may be provided, all of which are within the protection scope of this invention.

[0086] In addition, combined Figure 1 As shown, in this embodiment, the reinforcing unit 2 extends parallel to the extension direction of the connecting lines at both ends of the grid 1 along the Y-axis. Based on this, the extension direction of the reinforcing unit 2 can be easily determined, thereby achieving the technical effect of improving the ease of installation of the photovoltaic panel and the grid 1.

[0087] Of course, in other embodiments, depending on the design of the building photovoltaic integrated device, the relationship between the extension direction of the photovoltaic panel and the extension direction of the connecting lines at both ends of the grid 1 along the Y-axis can be adjusted. Alternatively, the extension direction of the photovoltaic panel and the extension direction of the connecting lines at both ends of the grid 1 along the Y-axis can form an angle with each other.

[0088] In addition, combined Figure 1 As shown, in this embodiment, the grid frame 1 includes bolt balls 102 and fixing units 103, with multiple bolt balls 102 and fixing units 103 provided. Adjacent fixing units 103 are connected by bolt balls 102. The building-integrated photovoltaic (BIPV) device includes:

[0089] The first connecting structure 4 has one end connected to the bolt ball 102, and the other end of the first connecting structure 4 is provided with a first through hole 402. The first through hole 402 is used to pass through the first suspension line 3, and the first suspension line 3 is connected to the first connecting structure 4.

[0090] Since multiple fixing units 103 are already connected to the bolt ball 102, the remaining installation space for the bolt ball 102 is relatively small. By setting the first connecting structure 4, the first connecting structure 4 can be directly connected to the bolt ball 102, and the first connecting structure 4 can also be connected to the first suspension line 3, increasing the installation space between the bolt ball 102 and the first suspension line 3. This simplifies the connection difficulty between the bolt ball 102 and the reinforcing unit 2, thereby achieving the technical effect of improving the ease of manufacturing and reliability of the building photovoltaic integrated device.

[0091] In this embodiment, the fixing unit 103 is a rod-shaped structure, and the fixing unit 103 and the bolt ball 102 are made of the same material, which will not be described in detail here.

[0092] Specifically, multiple first connecting structures 4 are provided, and the number of first connecting structures 4 is twice the number of first suspension wires 3, so that both ends of the first suspension wires 3 are connected to the bolt ball 102 through the first connecting structure 4. As an alternative implementation, the building-integrated photovoltaic device may not include the first connecting structure. In this case, the structure of the bolt ball 102 is adjusted so that the first suspension wires 3 can be fixed on the bolt ball 102.

[0093] Furthermore, the first connecting structure 4 has a mounting groove 401 on the side near the bolt ball 102. The mounting groove 401 communicates with the first through hole 402 and is used to accommodate the bolt ball 102 and one end of the first suspension wire 3. Based on this, the connection area between the first connecting structure 4 and the bolt ball 102 can be increased, thereby achieving the technical effect of improving the connection reliability between the first connecting structure 4 and the bolt ball 102.

[0094] Specifically, the first connecting structure 4 is a block structure, and the surface of the first connecting structure 4 that connects with the bolt ball 102 is arc-shaped, so that the first connecting structure 4 can be adapted to the shape of the bolt ball 102, thereby increasing the connection area between the first connecting structure 4 and the bolt ball 102, and thus achieving the technical effect of improving the connection reliability between the first connecting structure 4 and the bolt ball 102.

[0095] Of course, in other embodiments, the shape of the fixing unit 103 may be adjusted according to the different designs of the building photovoltaic integrated device. Alternatively, the fixing unit 103 and the bolt ball 102 may be made of different materials, all of which are within the protection scope of this invention.

[0096] In other embodiments, the shape of the first connecting structure 303 may be adjusted depending on the design of the building-integrated photovoltaic (BIPV) device. For example, the first connecting structure 303 may be a plate-like structure, in which case the connection between the first connecting structure 4 and the bolt ball 102 is at a single point. Alternatively, the surface shape of the first connecting structure 303 that connects to the bolt ball 102 may be adjusted.

[0097] In addition, combined Figure 1 As shown, in this embodiment, the building-integrated photovoltaic (BIPV) device includes:

[0098] The intermediate structure 5 is located between the space frame 1 and the reinforcing unit 2. The intermediate structure 5 has a second through hole for passing through and connecting the other end of the first suspension wire 3. The intermediate structure 5 is connected to the reinforcing unit 2. The intermediate structure 5 is a steel beam.

[0099] By setting the intermediate structure 5, it can serve as a transfer connection point between the space frame 1 and the reinforcing unit 2, thereby improving the connection rigidity between the space frame 1 and the reinforcing unit 2. This allows the first suspension line 3 between the space frame 1 and the reinforcing unit 2 to absorb impact force and ensure the reliability of the connection between the space frame 1 and the reinforcing unit 2.

[0100] As an alternative implementation, the building-integrated photovoltaic device may not include the intermediate structure 5, and the first suspension line 3 may be directly connected to the reinforcement unit 2.

[0101] Of course, in other embodiments, the type and material of the intermediate structure 5 may be adjusted according to the different designs of the building photovoltaic integrated device; for example, it may also be a steel plate.

[0102] In addition, combined Figure 1 As shown, in this embodiment, the intermediate structure 5 is provided with a third through hole, and the building-integrated photovoltaic device includes:

[0103] The second suspension line 6 has its two ends connected to the intermediate structures 5 at both ends of the reinforcing unit 2, that is, one end of the second suspension line 6 is connected to the intermediate structure 5 at one end of the reinforcing unit 2, and the other end of the second suspension line 6 is connected to the intermediate structure 5 at the other end of the reinforcing unit 2, for supporting the reinforcing unit 2.

[0104] Among them, along parallel to Figure 1 Multiple rows of reinforcing units 2 are arranged along the X-axis, each row of reinforcing units 2 is parallel to the Y-axis, and each row of reinforcing units 2 is composed of multiple reinforcing units 2 connected together. Each row of reinforcing units 2 is provided with two second suspension lines 6, which can improve the technical effect of the connection reliability between the reinforcing units 2 and the intermediate structure 5. The connection method between the second suspension lines 6 and the reinforcing units 2 is not limited. It can be welding, or it can be connecting the second suspension lines 6 to the reinforcing units 2 through an arched positioning plate, and then connecting the second suspension lines 6 to the reinforcing units 2 through bolts passing through the arched positioning plate and threadedly connected. Both are within the protection scope of this invention.

[0105] By setting a second suspension line 6, the length of the suspension line used in the building photovoltaic integrated device can be increased, so that when the reinforcing unit 2 is subjected to impact force, it can be converted into the internal force of the second suspension line 6, reducing the possibility of the impact force being transmitted to the grid frame 1, thereby achieving the technical effect of improving the structural stability of the building photovoltaic integrated device.

[0106] In this embodiment, both the first suspension wire 3 and the second suspension wire 6 are steel strands. Of course, in other embodiments, the specific materials of the first suspension wire 3 and the second suspension wire 6 may be adjusted depending on the design of the building-integrated photovoltaic device.

[0107] Preferably, in this embodiment, the radial dimensions of the first through hole 402 and the second through hole are both larger than the radial dimension of the first suspension wire 3, and the radial dimension of the third through hole is larger than the radial dimension of the second suspension wire 6. Based on this, the position of the first suspension wire 3 passing through the first through hole 402 and the second through hole can be adjusted according to the connection position between the bolt ball 102 and the reinforcing unit 2, i.e., the tilt angle of the first suspension wire 3 can be adjusted. Simultaneously, the position of the second suspension wire 6 passing through the third through hole can be adjusted, i.e., the tilt angle of the second suspension wire 6 can be adjusted. Based on this, the connection reliability between the space frame 1 and the intermediate structure 5 can be improved, and the technical effect of improving the connection reliability between the reinforcing unit 2 and the intermediate structure 5 can be achieved.

[0108] In this embodiment, the first through hole 402, the second through hole, and the third through hole are all oblong in shape. Of course, in other embodiments, the shapes of the first through hole 402, the second through hole, and the third through hole may be adjusted according to the design of the building-integrated photovoltaic device. For example, the first through hole 402, the second through hole, and the third through hole may be circular, all of which are within the scope of protection of this invention.

[0109] As an alternative implementation, the radial dimensions of the first through hole 402 and the second through hole may be equal to the radial dimension of the first suspension wire 3, and the radial dimension of the third through hole may be equal to the radial dimension of the second suspension wire 6, all of which are within the protection scope of this invention.

[0110] In other embodiments, depending on the design of the building-integrated photovoltaic (BIPV) device, the first through hole 402 may be a waist-shaped hole, the second through hole may be a waist-shaped hole, and the BIPV device may include one or more structures such as the second suspension wire 6, all of which are within the protection scope of this invention.

[0111] Alternatively, the building-integrated photovoltaic (BIPV) device may not include the second suspension line 6, and the intermediate structure 5 may be directly connected to the reinforcement unit 2.

[0112] In addition, combined Figure 2 , Figure 3 and Figure 7As shown, in this embodiment, the building-integrated photovoltaic (BIPV) device includes:

[0113] The first limiting unit 8 is disposed in the mounting groove 401 and connected to the first connecting structure 4. The first limiting unit 8 includes a first limiting structure 801 and a second limiting structure 802. The first limiting structure 801 and the second limiting structure 802 are spaced apart. The space is used to accommodate one end of the first suspension wire 3 so as to limit the position of the first suspension wire 3 by the space.

[0114] The second limiting unit 9 is located on the side of the intermediate structure 5 away from the first connecting structure 4. The second limiting unit 9 is connected to the intermediate structure 5. The second limiting unit 9 includes a third limiting structure 901 and a fourth limiting structure 902. The third limiting structure 901 and the fourth limiting structure 902 are spaced apart and located at both ends of the second through hole. The spaced interval is used to accommodate the other end of the first suspension wire 3, so as to limit the position of the first suspension wire 3 by the spaced interval.

[0115] At least two third limiting units are provided and are located at both ends of the second suspension line 6. The third limiting unit is located on the side of the intermediate structure 5 near the first connecting structure 4 and is connected to the intermediate structure 5. The third limiting unit includes a fifth limiting structure and a sixth limiting structure. The fifth limiting structure and the sixth limiting structure are spaced apart and are located at both ends of the third through hole. The interval is used to limit the position of the second suspension line 6.

[0116] The first limiting unit 8, the second limiting unit 9, and the third limiting unit have the same structure. Taking the first limiting unit 8 as an example, the first limiting structure 801 and the second limiting structure 802, which are set at intervals, can initially limit one end of the first suspension line 3, so that one end of the first suspension line 3 can move within the interval between the first limiting structure 801 and the second limiting structure 802. When the first suspension line 3 can tilt with the tilt between the bolt ball 102 and the reinforcing unit 2, the stability of the position of the first suspension line 3 can also be improved, thereby achieving the technical effect of improving the connection reliability between the bolt ball 102 and the reinforcing unit 2.

[0117] Similarly, the second limiting unit 9 can improve the stability of the other end of the first suspension line 3. The third limiting unit is located at both ends of the second suspension line 6, that is, there are two third limiting units. One third limiting unit is connected to one end of the second suspension line 6, and the other third limiting unit is connected to the other end of the second suspension line 6. The technical effect of improving the reliability and stability of the positions at both ends of the second suspension line 6 can be achieved through the third limiting unit.

[0118] Among them, the first limiting structure 801, the second limiting structure 802, the third limiting structure 901, the fourth limiting structure 902, the fifth limiting structure and the sixth limiting structure are plate-shaped structures. Of course, in other embodiments, the types and shapes of the first limiting structure 801, the second limiting structure 802, the third limiting structure 901, the fourth limiting structure 902, the fifth limiting structure and the sixth limiting structure are adjusted according to the different designs of the building photovoltaic integrated device.

[0119] Of course, in other embodiments, the structures of the first limiting unit 8, the second limiting unit 9, and the third limiting unit may be adjusted according to the different designs of the building-integrated photovoltaic device, all of which are within the scope of protection of this invention. Alternatively, the structures of the first limiting unit 8, the second limiting unit 9, and the third limiting unit may be different.

[0120] Alternatively, the building-integrated photovoltaic (BIPV) device may include one or more of the first limiting unit 8, the second limiting unit 9, and the third limiting unit, or the building-integrated photovoltaic (BIPV) device may not include the first limiting unit 8, the second limiting unit 9, and the third limiting unit.

[0121] In other embodiments, depending on the design of the building-integrated photovoltaic device, the following are all within the protection scope of the present invention: the first connecting structure 4 is provided with an installation groove 401 on the side near the bolt ball 102; the radial dimension of the first through hole 402 is greater than the radial dimension of the first suspension wire 3; the integrated photovoltaic device includes an intermediate structure 5; and the integrated photovoltaic device includes a first limiting unit 8.

[0122] In addition, combined Figure 3 and Figure 4 As shown, in this embodiment, the building-integrated photovoltaic (BIPV) device includes:

[0123] The first positioning structure 7 is disposed in the mounting groove 401. The first positioning structure 7 includes a first channel for accommodating one end of the first suspension wire 3. The radial dimension of the first channel is larger than the radial dimension of the first through hole 402. It is used to fix one end of the first suspension wire 3 in the mounting groove 401 to connect the first suspension wire 3 and the bolt ball 102.

[0124] The second positioning structure 10 includes a second channel for accommodating the other end of the first suspension wire 3. The radial dimension of the second channel is greater than the radial dimension of the second through hole, so that the other end of the first suspension wire 3 passes through the second through hole from one side of the intermediate structure 5 to the other side of the intermediate structure 5, and the other end of the first suspension wire 3 is fixed to the other side of the intermediate structure 5 by the second positioning structure 10, so as to connect the other end of the first suspension wire 3 with the intermediate structure 5.

[0125] There are two third positioning structures: one connected to one end of the second suspension wire 6, and the other connected to the other end. Taking the connection of one third positioning structure to one end of the second suspension wire 6 as an example, the third positioning structure includes a third channel for accommodating one end of the second suspension wire 6. The radial dimension of the third channel is larger than the radial dimension of the third through hole, allowing one end of the second suspension wire 6 to pass through the third through hole from the other side of the intermediate structure 5 to one side of the intermediate structure 5. The third positioning structure then fixes one end of the second suspension wire 6 to one side of the intermediate structure 5, thus connecting one end of the second suspension wire 6 to the intermediate structure 5.

[0126] Similarly, the third channel of another third positioning structure is used to accommodate the other end of the second suspension wire 6. The radial dimension of the third channel is larger than the radial dimension of the third through hole, so that the other end of the second suspension wire 6 passes through the third through hole from the other side of the intermediate structure 5 to one side of the intermediate structure 5, and the other end of the second suspension wire 6 is fixed to one side of the intermediate structure 5 by the third positioning structure, so as to connect the other end of the second suspension wire 6 with the intermediate structure 5.

[0127] The first positioning structure 7, the second positioning structure 10, and the third positioning structure have the same specific structure, and can all be anchors. Taking the first positioning structure 7 as an example, by setting the first positioning structure 7, the first limiting unit 8 can act as a knot for the first suspension line 3, fixing one end of the first suspension line 3 in the mounting groove 401 without detaching from the mounting groove 401, thereby achieving the technical effect of improving the position reliability of the first suspension line 3, so as to achieve a stable connection between one end of the first suspension line 3 and the first connecting structure 4, and thus achieving the technical effect of improving the reliability of the building photovoltaic integrated device.

[0128] Similarly, the second positioning structure 10 can achieve the technical effect of improving the reliability of the other end of the first suspension wire 3 being positioned on the other side of the intermediate structure 5. Two third positioning structures are provided: one at one end of the second suspension wire 6 and the other at the other end of the second suspension wire 6. This is to limit the positions of both ends of the second suspension wire 6 relative to the third through hole, and to improve the technical effect of improving the reliability of the second suspension wire 6 being positioned on one side of the intermediate structure 5, thereby achieving the technical effect of improving the reliability of the building-integrated photovoltaic (BIPV) device.

[0129] Of course, in other embodiments, depending on the design of the building photovoltaic integrated device, the building photovoltaic integrated device may include one or more of the following structures: the first positioning structure 7, the second positioning structure 10, the third positioning structure, the second limiting unit 9, and the third limiting unit. All of these are within the protection scope of this invention.

[0130] In other embodiments, the specific structures of the first positioning structure 7, the second positioning structure 10, and the third positioning structure are adjusted according to the different designs of the building-integrated photovoltaic (BIPV) device. Alternatively, the specific structures of the first positioning structure 7, the second positioning structure 10, and the third positioning structure may be different.

[0131] In addition, combined Figure 3 As shown, in this embodiment, the first limiting unit 8 is provided with a first arc groove, and the second limiting unit 9 is provided with a second arc groove. The building-integrated photovoltaic device includes:

[0132] Two first rotating structures 11 are provided. One first rotating structure 11 is provided on the first limiting unit 8 and is provided in the first arc groove. The shape of the first rotating structure 11 is matched with the shape of the first arc groove, that is, the shape of the first rotating structure 11 is the same as the shape of the first arc groove, both being arc-shaped.

[0133] Another first rotating structure 11 is disposed on the second limiting unit 9 and disposed in the second arc groove. The shape of the other first rotating structure 11 is matched with the shape of the second arc groove, that is, the shape of the other first rotating structure 11 is the same as the shape of the second arc groove, both being arc-shaped.

[0134] Each first rotating structure 11 is provided with a first fixing groove 1104 having the same radial dimension as the first suspension wire 3. The first fixing groove 1104 of one first rotating structure 11 is used to accommodate one end of the first suspension wire 3, and the first fixing groove 1104 of the other first rotating structure 11 is used to accommodate the other end of the first suspension wire 3. According to the tilt angle of the first suspension wire 3 during installation, the position of one first rotating structure 11 in the first arc groove is adjusted, and the position of the other first rotating structure 11 in the second arc groove is adjusted, so that the first fixing groove 1104 of one first rotating structure 11 can be provided on the extension path of one end of the first suspension wire 3, and the first fixing groove 1104 of the other first rotating structure 11 can be provided on the extension path of the other end of the first suspension wire 3.

[0135] Meanwhile, each third limiting unit is equipped with a third arc groove, and the building-integrated photovoltaic device includes:

[0136] The second rotating structure is located within the third arcuate groove, and its shape is designed to fit the third arcuate groove. The second rotating structure has a second fixing groove with the same radial dimension as the second suspension wire 6; that is, the shape of the second rotating structure and the third arcuate groove are both arc-shaped. The second fixing groove is used to accommodate one end or the other end of the second suspension wire 6, allowing adjustment of the position of the second rotating structure within the third arcuate groove according to the tilt angle of the second suspension wire 6 during installation. This ensures that the second fixing groove is positioned along the extension path of the second suspension wire 6, thereby improving the reliability of the second suspension wire 6's position.

[0137] By setting the first rotating structure 11, when the first rotating structure 11 is not connected to the first limiting unit 8, the first rotating structure 11 can rotate within the first or second arcuate groove along with the first suspension line 3, that is, in Figure 3 The YZ plane is rotated, and then one first rotating structure 11 is fixed to the inner wall of the first arc groove, and another first rotating structure 11 is fixed to the inner wall of the second arc groove, for example, by welding. Based on this, the first fixing groove 1104 can be positioned in the extension direction of the first suspension line 3, thereby improving the positional stability and reliability of the first suspension line 3.

[0138] The first rotating structure 11 and the second rotating structure have the same specific structure. Similarly, by setting the second rotating structure, when the second rotating structure is not connected to the second limiting unit 9, the second rotating structure can rotate within the third arc groove as the second suspension line 6 tilts. Then, the second rotating structure is fixed to the inner wall of the third arc groove, for example, by welding. Based on this, the technical effect of improving the positional reliability of the second suspension line 6 can be achieved.

[0139] Preferably, combined with Figure 3 As shown, the first limiting structure 801 and the second limiting structure 802 are each provided with a first arc groove, the third limiting structure 901 and the fourth limiting structure 902 are each provided with a second arc groove, and the fifth limiting structure and the sixth limiting structure are each provided with a third arc groove. Based on this, the technical effect of improving the connection reliability between one first rotating structure 11 and the first arc groove, between another first rotating structure 11 and the second arc groove, and between the second rotating structure and the third arc groove can be achieved.

[0140] As an alternative implementation, the number of the first, second, and third arc grooves can be adjusted, for example, each of the first, second, and third arc grooves can be provided.

[0141] Of course, in other embodiments, depending on the design of the building-integrated photovoltaic (BIPV) device, the first limiting unit 8 may have a first arc groove, the second limiting unit 9 may have a second arc groove, and the BIPV device may include one or more structures such as the first rotating structure 11; all of these are within the scope of protection of this invention. Alternatively, the first rotating structure 11 and the second rotating structure may be different.

[0142] In other embodiments, depending on the design of the building photovoltaic integrated device, the first rotating structure 11 may be provided only on the first limiting unit 8, the first rotating structure 11 may be provided only on the second limiting unit 9, and the second rotating structure may be used only at one end of the second suspension wire 6. All of these combinations of one or more structures are within the protection scope of this invention.

[0143] In addition, combined Figure 5 and Figure 6 As shown, in this embodiment, the specific structures of the first rotating structure 11 and the second rotating structure are the same. Taking the first rotating structure 11 as an example, when the first rotating structure 11 is connected to the first limiting unit 8, the first rotating structure 11 includes:

[0144] The first rotating component 1101 is disposed in the first arc groove of the first limiting structure 801, and the shape of the first rotating component 1101 is the same as the shape of the first arc groove.

[0145] The second rotating component 1102 is disposed in the first arc groove of the second limiting structure 802, and the shape of the second rotating component 1102 is the same as the shape of the first arc groove.

[0146] The second connecting structure 1103 is provided with a first fixing groove 1104. The second connecting structure 1103 is connected to the side of the first rotating member 1101 that is close to the first positioning structure 7, and the second connecting structure 1103 is connected to the side of the second rotating member 1102 that is close to the first positioning structure 7.

[0147] By setting a first rotating component 1101, a second rotating component 1102, and a second connecting structure 1103, the second connecting structure 1103 can connect the first rotating component 1101 and the second rotating component 1102, thereby increasing the positional reliability of the first rotating component 1101 and the second rotating component 1102. At the same time, the second connecting structure 1103 can also limit the position of the first suspension line 3, thereby achieving the technical effect of improving the positional reliability of the first suspension line 3.

[0148] In this embodiment, the first rotating component 1101, the second rotating component 1102, and the second connecting structure 1103 are all plate-shaped structures. Of course, in other embodiments, the shapes of the first rotating component 1101, the second rotating component 1102, and the second connecting structure 1103 may be adjusted according to the different designs of the building-integrated photovoltaic device.

[0149] When the first rotating structure 11 is connected to the second limiting unit 9, the first rotating member 1101 is disposed in the second arc groove of the third limiting structure 901, and the shape of the first rotating member 1101 is the same as the shape of the second arc groove. The second rotating member 1102 is disposed in the second arc groove of the fourth rotating structure, and the shape of the second rotating member 1102 is the same as the shape of the second arc groove.

[0150] Furthermore, the second rotational structure is identical to the first rotational structure 11. Similarly, the second rotational structure includes:

[0151] The third rotating component is located in the third arc groove of the fifth limiting structure;

[0152] The fourth rotating component is located within the third arc groove of the sixth limiting structure;

[0153] The third connecting structure is provided with a second fixing groove for accommodating the second suspension wire 6. The third connecting structure is connected to the side of the third rotating member near the second positioning structure 10, and the third connecting structure is connected to the side of the fourth rotating member near the second positioning structure 10.

[0154] Of course, in other embodiments, the specific structures of the first rotating structure 11 and the second rotating structure may be adjusted according to the different designs of the building photovoltaic integrated device.

[0155] As an alternative implementation, the first rotating member 1101 may be disposed in the first arc groove of the second limiting structure 802, the second rotating member 1102 may be disposed in the first arc groove of the first limiting structure 801, or the third rotating member may be disposed in the third arc groove of the sixth limiting structure, and the fourth rotating member may be disposed in the third arc groove of the fifth limiting structure.

[0156] In other embodiments, the structures of the first rotating unit and the second rotating unit are adjusted according to the different designs of the building-integrated photovoltaic device.

[0157] In addition, in this embodiment, the building-integrated photovoltaic (BIPV) device includes:

[0158] The vibration damping unit 12 has three parts, which are respectively located between the first positioning structure 7 and the first rotating structure 11, between the second positioning structure 10 and the first rotating structure 11, and between the third positioning structure and the second rotating structure; the vibration damping unit 12 includes a fourth channel, which is used to pass through the first suspension wire 3 or the second suspension wire 6.

[0159] By setting up the vibration damping unit 12, the vibration damping effect can be achieved, reducing the impact of wind load and seismic load on the building photovoltaic integrated device, thereby improving the technical effect of improving the reliability of the building photovoltaic integrated device.

[0160] Among them, the shock absorption unit 12 is a spring. Springs are readily available, thereby achieving the technical effect of improving the ease of manufacturing of building photovoltaic integrated devices.

[0161] The damping unit 12 abuts between the first positioning structure 7 and the first rotating structure 11, between the second positioning structure 10 and the first rotating structure 11, and between the third positioning structure and the second rotating structure, reducing the number of welding points required, thereby achieving the technical effect of improving the ease of manufacturing of building photovoltaic integrated devices.

[0162] Of course, in other embodiments, the damping unit 12 may be fixed between the first positioning structure 7 and the first rotating structure 11, between the second positioning structure 10 and the first rotating structure 11, and between the third positioning structure and the second rotating structure. Alternatively, the type of damping unit 12 may be adjusted; any structure with elasticity is within the scope of protection of this invention.

[0163] As an alternative implementation, the building-integrated photovoltaic (BIPV) device may not include the vibration damping unit 12. Alternatively, the number of vibration damping units 12 may be adjusted, and they may be located at one or more positions between the first positioning structure 7 and the first rotating structure 11, between the second positioning structure 10 and the first rotating structure 11, and between the third positioning structure and the second rotating structure; all of these are within the scope of protection of this invention.

[0164] Preferably, the top of the grid frame 1 can be provided with a light-transmitting plate to protect the reinforcement unit 2 and ensure the light-receiving area of ​​the reinforcement unit 2, so as to protect the reinforcement unit 2 from the effects of wind and snow, thereby achieving the technical effect of improving the service life of the reinforcement unit 2. The specific material of the light-transmitting plate is not limited.

[0165] As an alternative implementation, the top of the space frame 1 may not be fitted with a light-transmitting panel.

[0166] Specifically, taking the installation of a row of reinforcing units 2 and the grid frame 1 as an example, the installation process of the building-integrated photovoltaic device in this embodiment is as follows:

[0167] First, connect each column of reinforcing units 2, and then weld and fix the intermediate structure 5 to the grid frame 1.

[0168] Next, the first connecting structure 4 and the first limiting unit 8 are welded and fixed before leaving the factory. One end of the first lifting wire 3 is passed into the mounting groove 401, and then the first rotating structure 11, the shock absorption unit 12 and the first positioning structure 7 are passed through one end of the first lifting wire 3 in sequence.

[0169] Then, the other end of the first suspension line 3 passes through the second through hole from one side of the middle structure 5 to the other side of the middle structure 5. Then, the second rotating structure, the shock absorption unit 12, and the second positioning structure 10 are passed through the other end of the first suspension line 3 in sequence. The tension of the first suspension line 3 is adjusted as needed. After the adjustment is completed, the first rotating structure 11 and the first limiting unit 8 are welded and fixed, and the second rotating structure and the second limiting unit 9 are welded and fixed.

[0170] Next, one end of the second suspension line 6 passes through the third through hole from the other side of the middle structure 5 to one side of the middle structure 5. Then, a third rotating structure, a shock-absorbing unit 12 and a third positioning structure are passed through one end of the second suspension line 6 in sequence, and the top of the second suspension line 6 is connected and fixed to each reinforcing unit 2.

[0171] Then, the other end of the second suspension line 6 passes through the third through hole from the other side of the middle structure 5 to one side of the middle structure 5. Then, another third rotating structure, the shock absorption unit 12 and another third positioning structure are passed through the other end of the second suspension line 6 in sequence. The tension of the second suspension line 6 is adjusted as needed. After the adjustment is completed, the third rotating structure and the third limiting unit are welded and fixed. The above operation is repeated until multiple first suspension lines 3 and multiple second suspension lines 6 are installed to complete the fabrication of the building photovoltaic integrated device.
