Description

Technical Field

[0001] The present invention belongs to the field of building technology, and more specifically, to a photovoltaic and seismic integrated device for existing buildings and its usage method. Background Art

[0002] With the continuous growth of the global demand for renewable energy, photovoltaic power generation technology, as a clean and sustainable energy utilization method, has been widely applied. Especially when installing photovoltaic power generation components on the roofs of existing buildings, it can not only make full use of the idle space of the buildings, but also effectively reduce carbon emissions and promote the optimization of the energy structure.

[0003] However, the roofs of existing buildings are composed of multi-layer brick-concrete structures and multi-layer frame structures. Then, an installation rack is set on the roof through a steel frame structure, and photovoltaic components are installed on the installation rack. Although the installation rack composed of the steel frame structure can fix the photovoltaic components, since the installation rack is a rigid structure, when the building is affected by external natural factors such as earthquakes, the damping effect of the installation rack is poor, resulting in the photovoltaic components being subjected to great external vibrations, which affects the stability of the reciprocating component installation. Therefore, after setting the installation rack on the existing roof, a damping component often needs to be set to damp the photovoltaic components through the damping component.

[0004] Existing photovoltaic components usually use damping pads or spring components, that is, a damping pad or a spring component is set between the installation rack and the photovoltaic components, and the vibration transmitted from the installation rack to the photovoltaic components is weakened through the damping pad or the spring component. However, the installation of the damping pad or the spring component will reduce the connection strength between the installation rack and the photovoltaic components, and the damping of the damping pad or the spring component is limited. When the existing building roof is subjected to great vibrations, the vibrations transmitted to the photovoltaic components will also increase, and in severe cases, the photovoltaic components will be damaged.

[0023] The present invention provides a method for using a photovoltaic and seismic integrated device for existing buildings, which is applied to a photovoltaic and seismic integrated device for existing buildings, and includes the following steps:

[0024] When the existing building is subjected to earthquake action, the movable assembly reciprocates on the parapet wall;

[0025] The movable assembly pulls the first connecting rod, so that one end of the first connecting rod away from the parapet wall reciprocates between the two F-shaped connecting pieces;

[0026] The first connecting rod pulls the second friction strip to slide repeatedly along the first friction strip;

[0027] During the sliding process, the second friction strip and the first friction strip rub against each other to do work to dissipate energy; the connection part between the flexible mounting frame and the first connecting rod slides reciprocally on the first connecting rod to keep the flexible mounting frame stable.

[0028] Compared with the prior art, the present invention has the following beneficial technical effects:

[0029] The present invention provides a photovoltaic and seismic integrated device for existing buildings. In this device, the second friction strip and the first friction strip in the shock-absorbing component slide relative to each other under the action of the first connecting rod. During the sliding process of the second friction strip and the first friction strip, they rub against each other to do work, effectively consuming the vibration energy transmitted from the existing building to the device, and effectively reducing the influence of seismic forces on the flexible mounting frame. Even when the building is affected by an earthquake, the flexible mounting frame can maintain a high degree of stability, ensuring that the photovoltaic panel can generate electricity continuously and stably, significantly improving the working stability of the photovoltaic panel and extending its service life. At the same time, the device has a compact structure and is easy to install, suitable for various existing building roofs, providing a strong guarantee for the safe and stable operation of the photovoltaic power generation system.

[0030] Furthermore, through the sliding fit between the second connecting rod and the connecting steel sleeve in this device, the flexible mounting frame can flexibly adapt to the displacement of the first connecting rod, ensuring the stability of the photovoltaic panel during an earthquake. A number of mounting sleeves rotatably installed on the second connecting rod, in cooperation with the connection of the connecting steel cable to the third connecting rod and the support vertical rod, constitute a stable and flexible support system. Then, the photovoltaic panel is installed between two adjacent connecting steel cables, which not only ensures sufficient light-receiving area but also ensures the structural stability.

[0031] Even further, the chute and the slider on the L-shaped connecting plate in this device, as well as the damper between the slider and the end of one side of the chute, provide additional shock-absorbing effects for the device. The damper can assist in absorbing and consuming vibration energy, further reducing the seismic influence on the photovoltaic panel, thereby enhancing the overall synergistic effect of the shock-absorbing component, improving the installation stability of the photovoltaic panel, and ensuring its long-term and stable power generation efficiency. At the same time, the damper can also improve the efficiency of the second friction strip returning to its initial position, facilitating the second friction strip to move again along the extension direction of the first friction strip and improving the friction energy consumption effect between the second friction strip and the first friction strip.

[0032] Even further, in this device, the metal clamping plate is movably clamped on the U-shaped steel plate to achieve flexible connection between the device and the parapet wall. The sliding fit between the sliding member inside the metal clamping plate and the fourth connecting rod enables the movable component to adaptively adjust its posture during an earthquake. The sliding setting of the track plate and the sliding head ensures the smoothness and stability of the sliding, further enhancing the reliability of the device.

[0033] Furthermore, in this device, through the combination of the first force-bearing support rod, the sixth connecting rod, the fifth connecting rod, and the first counterweight ball, a stable counterweight structure is formed, enhancing the stability of the device under non-seismic conditions. At the same time, during the installation of the metal splint, the first force-bearing support rod, the sixth connecting rod, and the fifth connecting rod facilitate the movement and installation of the installer, improving the installation efficiency. An inclined strut is arranged between the sixth connecting rod and the first force-bearing support rod, providing additional support for the counterweight structure and making the entire counterweight system more stable.

[0034] Furthermore, the combination of the arc-shaped connecting rod, the elastic connecting piece, and the second counterweight ball in this device provides additional shock absorption for the device. When the existing building is shaken, the elastic connecting piece can absorb part of the vibration energy, reducing the impact on the photovoltaic panel. In addition, the top of the first force-bearing support rod is connected to the first counterweight ball through the sixth connecting rod, further enhancing the counterweight effect, providing comprehensive and effective seismic protection for the photovoltaic power generation system, and ensuring its long-term and stable operation.

[0055] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0056] The present invention provides a photovoltaic and seismic integrated device for existing buildings, such as Figures 1 to 14As shown in the figure, it includes a shock absorption component installed on the building roof 2. A flexible mounting frame is installed above the shock absorption component, and a photovoltaic panel 26 is installed inside the flexible mounting frame. An active component is movably connected to the same-side ends of the flexible mounting frame and the shock absorption component, and the active component is installed on the parapet wall 1. For roofs with a rectangular or polygonal structure (where the number of sides is even), the parapet walls 1 where the active components connected to the two ends of the flexible mounting frame and the shock absorption component are located are parallel to each other. For irregular roofs, only one active component is connected to the flexible mounting frame and the shock absorption component, and this active component is located on the same side of the flexible mounting frame and the shock absorption component. When the building roof 2 is subjected to an earthquake, the active component will repeatedly flip on the parapet wall 1. The active component drives the shock absorption component to reciprocate, causing the interior of the shock absorption component to dissipate energy by friction work and reducing the sway amplitude of the flexible mounting frame, thereby enabling the photovoltaic panel 26 to operate stably and improving the stability of the installation of the photovoltaic panel 26.

[0057] As Figure 1 , Figure 2 , Figure 4 , Figure 5 , Figure 6 , Figure 9 , Figure 10 , Figure 11 and Figure 14As shown in the figure, the shock absorption assembly includes two F-shaped connectors 41, which are symmetrically arranged. A second connection bottom plate 42 is provided at the bottom end of the F-shaped connector 41, and the second connection bottom plate 42 is installed on the building roof 2. A plurality of first friction strips 23 are installed between the opposite side end faces of the two F-shaped connectors 41. The plurality of first friction strips 23 are arranged at equal intervals between the two F-shaped connectors 41. An L-shaped connecting plate 21 is installed on the building roof 2 at the positions of the same-side end heads of the two F-shaped connectors 41. A first connection bottom plate 22 is provided on the bottom end face of the L-shaped connecting plate 21, and the first connection bottom plate 22 is fixed to the building roof 2. The two L-shaped connecting plates 21 and the two F-shaped connectors 41 are butt-connected end to end to form a rectangle. A first friction strip 23 is slidably connected between the two L-shaped connecting plates 21. The projection lines of the first friction strip 23 and the second friction strip 24 on the building roof 2 are perpendicular to each other, and the second friction strip 24 is respectively woven and connected with a plurality of first friction strips 23. That is, at the connection of the second friction strip 24 and the first friction strip 23, when the second friction strip 24 is located above a first friction strip 23, the second friction strip 24 is located below the two adjacent first friction strips 23 of the first friction strip 23, forming a woven structure in which the second friction strip 24 is connected to a plurality of first friction strips 23. Among them, the second friction strip 24 includes a corrugated steel plate. Chamfers are provided on the edges of the corrugated steel plate. A high-friction rubber material layer is provided on the outer wall of the corrugated steel plate, and ribs or rivets are provided between the corrugated steel plate and the high-friction rubber material layer to reduce the slippage between the corrugated steel plate and the high-friction rubber material layer; the first friction strip 23 includes a metal plate. Chamfers are provided on the edges of the metal plate. A high-friction rubber material layer is provided on the outer wall of the metal plate, and ribs or rivets are provided between the metal plate and the high-friction rubber material layer to reduce the slippage between the metal plate and the high-friction rubber material layer;A plurality of connecting rings are arranged on the upper end surface of the second friction strip 24. Waterproof glue is coated at the connection between the connecting rings and the second friction strip 24 to prevent rainwater from entering the interior of the corrugated steel plate and the high-friction rubber layer, causing aging, cracking or damage inside the high-friction rubber layer. The plurality of connecting rings are arranged along the length direction of the second friction strip 24. A connecting hook is hooked inside each connecting ring. A U-shaped buckle is arranged at the opening position of the connecting hook. An anti-disengagement plate is installed at the opening of the U-shaped buckle. The cooperation between the anti-disengagement plate and the U-shaped buckle can prevent the connecting hook from disengaging from the connecting ring during an earthquake. A nut is screwed at the opening of the U-shaped buckle to prevent the anti-disengagement plate from the U-shaped buckle. One end of a first connecting rod 25 is connected to the connecting hook. The extending direction of the first connecting rod 25 is parallel to the extending direction of the L-shaped connecting plate 21. The other ends of all the first connecting rods 25 are movably connected to an activity component. A flexible mounting bracket is slidably connected to each of two adjacent first connecting rods 25. When the building is shaken, the activity component repeatedly flips on the parapet wall 1, and the activity component pulls the first connecting rod 25, so that the first connecting rod 25 drives the second friction strip 24 to repeatedly slide along the extending direction of the first friction strip 23. The second friction strip 24 and the first friction strip 23 rub against each other during the sliding process, and the energy is dissipated by relying on the friction work. At the same time, the connection between the flexible mounting bracket and the first connecting rod 25 slides back and forth on the first connecting rod 25 to keep the flexible mounting bracket stable, thereby weakening the influence of the earthquake on the photovoltaic panel 26 and improving the installation stability of the photovoltaic panel 26.

[0058] Such as Figures 1 to 6As shown, the flexible mounting bracket includes a second connecting rod 46. Connecting steel sleeves 33 are provided at both ends of the second connecting rod 46. The connecting steel sleeves 33 are slidably mounted on the first connecting rod 25. Ball bearings are provided inside the connecting steel sleeves 33, enabling the connecting steel sleeves 33 to slide on the first connecting rod 25 through the ball bearings. When the second connecting rods 46 in adjacent flexible mounting brackets are mounted on one first connecting rod 25, one connecting steel sleeve 33 is used for connection, making the adjacent flexible mounting brackets form an integral body. A number of mounting collars 47 are rotatably connected to the second connecting rod 46. Bearings are installed between the mounting collars 47 and the second connecting rod 46, enabling the mounting collars 47 to rotate on the second connecting rod 46. One end of a connecting steel cable 27 is connected to the outer wall of each mounting collar 47. The other end of the connecting steel cable 27 is connected to a third connecting rod 19. The connecting steel cable 27 and the third connecting rod 19 are connected through a metal cable clamp. The third connecting rod 19 and the second connecting rod 46 are parallel to each other, and in the initial position, their vertical distances from the building roof 2 are the same, so that the flexible mounting bracket is in a horizontal state. Support vertical rods 29 are vertically connected to both ends of the third connecting rod 19 respectively. The bottom end face of the support vertical rod 29 is mounted on the upper end face of the L-shaped connecting plate 21. The third connecting rod 19 is supported by the support vertical rods 29. Photovoltaic panels 26 are installed between adjacent connecting steel cables 27. The photovoltaic panels 26 and the connecting steel cables 27 are connected through metal buckles. When the existing building is vibrated, the movable assembly pulls the first connecting rod 25. During the movement of the first connecting rod 25, the connecting steel sleeve 33 slides on the first connecting rod 25, enabling the seventh connecting rod 46 to move along the axial direction of the first connecting rod 25. The mounting collar 47 rotates on the seventh connecting rod 46, enabling the flexible mounting bracket to maintain its initial installation state, improving the installation stability of the photovoltaic panel 26, and enabling the photovoltaic panel 26 to work stably.

[0059] As Figures 1 to 6As shown, on the opposite side end faces of the two L-shaped connecting plates 21, there are sliding grooves 28 opened along the length direction of the L-shaped connecting plates 21. A slider 36 is slidably installed in each sliding groove 28. A damper 37 is connected between the side of the slider 36 and one end of the sliding groove 28. Two connecting clamping plates 38 are symmetrically arranged on the outer wall of the slider 36. The end of the second friction strip 24 is fixedly connected between the two connecting clamping plates 38 by screws, and the second friction strip 24 is installed between the two L-shaped connecting plates 21. When the existing building is shaken, the damper 37 further assists the first friction strip 23 and the second friction strip 24 to dissipate seismic energy. In this embodiment, when the existing building is not shaken, the damper 37 should be in a slightly tensioned, compressed or unloaded state. The damper 37 adopts a low-damping type damper with a self-resetting function, such as a damper using SMA shape memory alloy wires. When the existing building is subjected to an earthquake, the damper 37 should dissipate as little seismic energy as possible to maximize the movement amplitude of the second friction strip 24 in the length direction of the multiple first friction strips 23, and the damper 37 also needs to be able to restore the second friction strip 24 to its initial state by adjusting the position of the slider 36 after the earthquake.

[0060] A limiting plate is also arranged in the sliding groove 28 to prevent the slider 36 from being too close to one end of the sliding groove 28, and to prevent the sliding head 40 from slipping out of the track plate 39 during frequent earthquakes, which may cause the metal clamping plate 14 to slide out of the U-shaped steel plate 11.

[0061] Such as Figure 1 、 Figure 2 、 Figure 4 、 Figure 5 、 Figure 7 、 Figure 12 and Figure 13As shown in the figure, one way of movably connecting the first connecting rod 25 to the parapet wall 1 is as follows: at one end of the first connecting rod 25 close to the parapet wall 1, a hinge ball assembly 34 is provided. A U-shaped steel plate 11 is sleeved on the parapet wall 1, and the U-shaped steel plate 11 is connected to the parapet wall 1 through fixing screws 18. That is, a first fixing hole is formed in the parapet wall 1, and a second fixing hole is formed in the outer wall of the U-shaped steel plate 11. After the U-shaped steel plate 11 is installed on the parapet wall 1, the first fixing hole is aligned with the second fixing hole. A fixing screw 18 is inserted through the aligned second fixing hole and the first fixing hole, and fixing nuts are screwed on the two ends of the fixing screw 18, and one end face of the fixing nut is attached to the outer wall of the U-shaped steel plate 11. During the installation process, in order to reduce the damage to the structure of the parapet wall 1 caused by forming multiple first fixing holes in the parapet wall 1, a U-shaped extended steel plate is provided at the end of the U-shaped steel plate 11. The U-shaped extended steel plate is installed on another parapet wall 1 connected to the parapet wall 1, and the connection between the U-shaped extended steel plate and the U-shaped steel plate 11 is located at the corner position of the parapet wall. The U-shaped extended steel plate and the parapet wall 1 are also fixed by fixing screws 18. Among them, if a U-shaped extended steel plate is provided at one end of the U-shaped steel plate 11, the U-shaped steel plate 11 and the U-shaped extended steel plate form a similar L-shaped structure. If U-shaped extended steel plates are provided at both ends of the U-shaped steel plate 11, the U-shaped steel plate 11 and the two U-shaped extended steel plates form a similar U-shaped structure or a similar Z-shaped structure, enhancing the connection reliability between the U-shaped steel plate 11 and the parapet wall 1 and preventing the U-shaped steel plate 11 from partially detaching from the parapet wall 1 during the process of the metal splint 14 repeatedly flipping around the U-shaped steel plate 11 during an earthquake. An activity component is installed on the side wall of the U-shaped steel plate 11, and a hinge ball assembly 34 is installed on the activity component. The connection between the first connecting rod 25 and the activity component can rotate through the hinge ball assembly 34.

[0062] Another way of movably connecting the first connecting rod 25 to the parapet wall 1 is as follows: a connection hole is provided at one end of the first connecting rod 25 close to the parapet wall 1. A shaft is rotatably connected in the connection hole, and fixing plates are respectively connected to the two ends of the shaft. The fixing plates are fixed to the activity component. When the activity component repeatedly flips on the U-shaped steel plate 11, the connection between the first connecting rod 25 and the activity component rotates through the rotation of the shaft in the connection hole.

[0063] Such as Figure 1 、 Figure 2 、 Figure 4 、 Figure 5 、 Figure 7 、 Figure 12 and Figure 13As shown in the figure, the movable component includes a metal splint 14. The metal splint 14 is movably clamped outside the U-shaped steel plate 11. The metal splint 14 is an M-shaped metal plate or a U-shaped plate with a closed end. An enlarged head 35 is provided at the port of the metal splint 14. The outer wall of the enlarged head 35 is attached to the side wall of the U-shaped steel plate 11. The enlarged head 35 facilitates the repeated flipping of the metal splint 14 around the U-shaped steel plate 11. A sliding member is provided on the inner top surface of the metal splint 14. One end of a fourth connecting rod 32 is slidably connected inside the sliding member, and the other end of the fourth connecting rod 32 is fixed to the top end surface of the U-shaped steel plate 11. The metal splint 14 is limited by the sliding member to prevent the metal splint 14 from detaching from the U-shaped steel plate 11 during frequent earthquakes. At the same time, it also enables the metal splint 14 to stably undergo repeated flipping on the U-shaped steel plate 11, improving the stability of the operation of this device.

[0064] As Figure 4 and Figure 8 shown, the sliding member includes a track plate 39. The extending direction of the track plate 39 is perpendicular to the extending direction of the parapet wall 1. A slide rail is provided on the bottom end surface of the track plate 39 along its extending direction. A slide head 40 is slidably connected inside the slide rail. The slide head 40 is fixed to the upper end of the fourth connecting rod 32. Through the sliding member, when the existing building is subjected to earthquake action, the metal splint 14 can stably undergo repeated flipping around the U-shaped steel plate 11.

[0065] As Figure 1 , Figure 2 , Figure 4 , Figure 5 , Figure 7 , Figure 12 and Figure 13As shown, a first counterweight is provided on the metal splint 14. The first counterweight includes a first force-bearing support rod 20, which is vertically fixed on the end face of the metal splint 14 on the side far from the first connecting rod 25. The first force-bearing support rod 20 is connected to the metal splint 14 by means of a buckle or welding. A fifth connecting rod 15 is provided at the top end of the first force-bearing support rod 20. The projection lines of the fifth connecting rod 15 and the first connecting rod 25 on the building roof 2 are perpendicular to each other. A sixth connecting rod 17 is provided on the outer wall of the fifth connecting rod 15. The projection line of the vertical projection of the fifth connecting rod 15 on the upper end face of the metal splint 14 and the projection line of the vertical projection of the sixth connecting rod 17 on the upper end face of the metal splint 14 are perpendicular to each other. A first counterweight ball 16 is provided at the end of the sixth connecting rod 17 far from the fifth connecting rod 15. In this embodiment, the first counterweight ball 16 is a metal body with a small volume but a large weight. An inclined strut 31 is provided between the outer wall of the sixth connecting rod 17 and the outer wall of the fifth connecting rod 15 to increase the connection stability between the sixth connecting rod 17 and the fifth connecting rod 15. A second force-bearing support rod 30 is provided on the end face of the metal splint 14 opposite to the first connecting rod 25. The second force-bearing support rod 30 is connected to the metal splint 14 by means of a buckle or welding. The second force-bearing support rod 30 corresponds to the first force-bearing support rod 20 one by one. A seventh connecting rod 12 is provided at the top end of the second force-bearing support rod 30. The seventh connecting rod 12 is parallel to the fifth connecting rod 15. All the seventh connecting rods 12 provided on the metal splints 14 located on the same parapet wall 1 are commonly connected to an open steel sleeve 13. The open steel sleeve 13 enables all the metal splints 14 on the same parapet wall 1 to synchronously and repeatedly flip when subjected to seismic forces, so that all the first connecting rods 25 have a synchronous movement tendency.

[0066] As Figure 12 shown, the first counterweight further includes an arc-shaped connecting rod 43. One end of the arc-shaped connecting rod 43 is fixed on the top end face of the metal splint 14. The other end of the arc-shaped connecting rod 43 faces the building roof 2. An elastic connecting piece 44 is connected to the end of the arc-shaped connecting rod 43 facing the building roof 2. A second counterweight ball 45 is connected to the elastic connecting piece 44. The second counterweight ball 45 and the elastic connecting piece 44 can increase the flipping frequency of the metal splint 14 around the U-shaped steel plate 11 during an earthquake, that is, can further increase the repeated sliding frequency of the second friction strip 24 along the extension direction of the multiple first friction strips 23, enhancing the energy dissipation effect.

[0067] The present invention also proposes a usage method of a photovoltaic and seismic integrated device for existing buildings, which is applied to the above-mentioned photovoltaic and seismic integrated device for existing buildings, and includes the following steps:

[0068] When the existing building is shaken, the movable component reciprocally flips on the parapet wall 1;

[0069] The movable component pulls the first connecting rod 25, so that the other end of the first connecting rod 25 away from the parapet wall 1 reciprocally moves between two F-shaped connecting pieces 41;

[0070] The first connecting rod 25 pulls the second friction strip 24 to slide repeatedly along the first friction strip 23;

[0071] The second friction strip 24 and the first friction strip 23 do work by friction with each other during the sliding process to dissipate energy; at the same time, the connection part between the flexible mounting bracket and the first connecting rod 25 slides reciprocally on the first connecting rod 25 to keep the flexible mounting bracket stable.

[0072] Specifically, when the existing building is not shaken, the first counterweight ball 16 and the second counterweight ball 45 make the top of the metal splint 14 tilt towards the building roof 2 to keep the metal splint 14 stable. At the same time, the damper 37 should be in a slightly tensioned, compressed or non-loaded state, and the photovoltaic panel 26 also remains stable in the horizontal plane;

[0073] When the existing building is shaken, the metal splint 14 installed on the U-shaped steel plate 11 in the movable component reciprocally flips on the parapet wall 1. At the same time, under the action of the first counterweight ball 16 and the second counterweight ball 45, the metal splint 14 flips more frequently. At this time, the slider 40 slides in the slide rail on the track plate 39;

[0074] During the reciprocal flipping process of the metal splint 14, it drives the first connecting rod 25, so that the other end of the first connecting rod 25 away from the parapet wall 1 reciprocally moves between two F-shaped connecting pieces 41. At the same time, the connecting steel sleeve 33 slides on the first connecting rod 25, making the second connecting rod 46 slide between two connecting steel cables 27. At this time, the mounting ferrule 47 rotates on the second connecting rod 46;

[0075] The first connecting rod 25 drives the second friction strip 24 to slide repeatedly along the extension direction of the first friction strip 23. The second friction strip 24 and the first friction strip 23 do work by friction with each other during the sliding process to dissipate energy; after the first connecting rod 25 drives the second friction strip 24 to move a certain distance between two F-shaped connecting pieces 41, the damper 37 increases the power for the second friction strip 24 to return to the initial position, so that the second friction strip 24 quickly returns to the initial position, facilitating moving along the extension direction of the first friction strip 23 again, facilitating the friction energy dissipation between the second friction strip 24 and the first friction strip 23 while ensuring the installation stability of the photovoltaic panel 26.
