Description

Technical Field

[0001] The present invention belongs to the field of building technology, and in particular to a photovoltaic and earthquake-resistant integrated device for an existing building and a use method thereof. Background Art

[0002] As the global demand for renewable energy continues to grow, photovoltaic power generation technology has been widely used as a clean and sustainable way of energy utilization. In particular, installing photovoltaic power generation components on the roofs of existing buildings can not only make full use of the idle space of the building, but also effectively reduce carbon emissions and promote the optimization of the energy structure.

[0003] However, the roof of the existing building is composed of a multi-layer brick-concrete structure and a multi-layer frame structure, and then a mounting frame is set on the roof through a steel frame structure, and photovoltaic modules are installed on the mounting frame. Although the mounting frame composed of the steel frame structure can fix the photovoltaic modules, since the mounting frame is a rigid structure, when the house is affected by external natural factors such as earthquakes, the shock-absorbing effect of the mounting frame is poor, causing the photovoltaic modules to receive great external force vibrations, affecting the stability of the reciprocating module installation. Therefore, after the mounting frame is set on the existing roof, it is often necessary to set a shock-absorbing component to reduce the shock of the photovoltaic modules through the shock-absorbing component.

[0004] Existing photovoltaic modules usually use shock-absorbing pads or spring assemblies, that is, shock-absorbing pads or spring assemblies are arranged between the mounting frame and the photovoltaic module. The shock-absorbing pads or spring assemblies weaken the vibration transmitted from the mounting frame to the photovoltaic module. Then, the installation of the shock-absorbing pads or spring assemblies will reduce the strength of the connection between the mounting frame and the photovoltaic module, and the shock-absorbing effect of the shock-absorbing pads or spring assemblies is limited. When the roof of the existing building is subjected to great vibration, the vibration transmitted to the photovoltaic module will also increase, which may cause damage to the photovoltaic module in severe cases.

[0015] The present invention proposes a method for using a photovoltaic and earthquake-resistant integrated device for an existing building, which is applied to a photovoltaic and earthquake-resistant integrated device for an existing building, and comprises the following steps: When an existing building is subjected to earthquake action, the movable components reciprocate on the parapet; The movable assembly pulls the first connecting rod so that an end of the first connecting rod away from the parapet moves back and forth between the two F-shaped connecting members; The first connecting rod pulls the second friction strip to slide repeatedly along the first friction strip; The second friction strip and the first friction strip rub against each other during the sliding process to dissipate energy; the connection between the flexible mounting frame and the first connecting rod reciprocates on the first connecting rod to keep the flexible mounting frame stable.

[0016] Compared with the prior art, the present invention has the following beneficial technical effects: The present invention proposes a photovoltaic and earthquake-resistant integrated device for existing buildings. The second friction strip and the first friction strip in the shock-absorbing component of the device slide against each other under the action of the first connecting rod. The second friction strip and the first friction strip rub against each other during the sliding process, which effectively consumes the vibration energy transmitted to the device by the existing building and effectively reduces the influence of the earthquake force 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 panels can generate electricity continuously and stably, significantly improving the working stability of the photovoltaic panels and extending their service life. At the same time, the device has a compact structure and is easy to install. It is suitable for various existing building roofs and provides a strong guarantee for the safe and stable operation of the photovoltaic power generation system.

[0017] Furthermore, in this device, the sliding cooperation between the second connecting rod and the connecting steel sleeve enables the flexible mounting frame to flexibly adapt to the displacement of the first connecting rod, thereby ensuring the stability of the photovoltaic panel during earthquakes. Several mounting sleeves rotatably installed on the second connecting rod, in conjunction with the connection between the connecting steel cable and the third connecting rod and the supporting vertical pole, constitute a stable and flexible support system, thereby enabling the photovoltaic panel to be installed between two adjacent connecting steel cables, thereby ensuring both sufficient light-receiving area and the stability of the structure.

[0018] Furthermore, the slide groove and slider on the L-shaped connecting plate in the device, as well as the damper between the slider and the end of one side of the slide groove, provide an additional shock-absorbing effect for the device. The damper can assist in absorbing and consuming vibration energy, further reducing the impact of earthquakes on the photovoltaic panels, thereby enhancing the overall synergy of the shock-absorbing components, improving the installation stability of the photovoltaic panels, and ensuring their 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, so as to facilitate the second friction strip to move again along the extension direction of the first friction strip, and improve the friction energy dissipation effect between the second friction strip and the first friction strip.

[0019] Furthermore, in this device, a metal clamp is movably clamped on the U-shaped steel plate, thereby achieving a flexible connection between the device and the parapet. The sliding part inside the metal clamp cooperates with the sliding of the fourth connecting rod, so that the movable component can adaptively adjust its posture during earthquakes. The sliding setting of the track plate and the slider ensures the smoothness and stability of the sliding, further improving the reliability of the device.

[0020] Furthermore, in this device, a stable counterweight structure is formed through the combination of the first force-bearing support rod, the sixth connecting rod, the fifth connecting rod and the first counterweight ball, which enhances 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 can facilitate the movement and installation of the installers, thereby improving the installation efficiency, and a diagonal strut is arranged between the sixth connecting rod and the first force-bearing support rod to provide additional support for the counterweight structure, thereby making the entire counterweight system more stable.

[0021] Furthermore, the combination of the arc-shaped connecting rod, the elastic connecting piece and the second counterweight ball in the present device provides an additional shock-absorbing effect for the device. When the existing building is vibrated, 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, which further enhances the counterweight effect, provides comprehensive and effective earthquake protection for the photovoltaic power generation system, and ensures its long-term and stable operation.

[0028] The embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0029] The present invention proposes a photovoltaic and earthquake-resistant integrated device for existing buildings, such as Figure 1 to Figure 14As shown, it includes a shock-absorbing component installed on the building roof 2, a flexible mounting frame is installed above the shock-absorbing component, a photovoltaic panel 26 is installed in the flexible mounting frame, and an active component is movably connected to the same side end of the flexible mounting frame and the shock-absorbing component, and the active component is installed on the parapet 1. For a roof with a rectangular structure or a polygonal structure (the variable is an even number), the parapet 1 where the active component is located at the ends of the flexible mounting frame and the shock-absorbing component is connected is parallel to each other. For an irregular roof, only one active component is connected to the flexible mounting frame and the shock-absorbing component, and the active component is located on the same side of the flexible mounting frame and the shock-absorbing component; when the building roof 2 is subjected to an earthquake, the active component will repeatedly flip over on the parapet 1; the active component drives the shock-absorbing component to reciprocate, so that the interior of the shock-absorbing component dissipates energy by doing work by friction, and reduces the shaking amplitude of the flexible mounting frame, thereby making the photovoltaic panel 26 run stably and improving the stability of the installation of the photovoltaic panel 26.

[0030] like Figure 1 , Figure 2 , Figure 4 , Figure 5 , Figure 6 , Fig. 9 , Fig.10 , Fig.11 and Fig.14As shown, the shock absorbing assembly includes two F-type connectors 41, the two F-type connectors 41 are symmetrically arranged, a second connecting bottom plate 42 is arranged on the bottom end of the F-type connector 41, the second connecting bottom plate 42 is installed on the building roof 2, a plurality of first friction strips 23 are installed between the opposite side end surfaces of the two F-type connectors 41, and the plurality of first friction strips 23 are arranged at equal intervals between the two F-type connectors 41, an L-shaped connecting plate 21 is installed on the building roof 2 at the same side end of the two F-type connectors 41, a first connecting bottom plate 22 is arranged on the bottom end surface of the L-shaped connecting plate 21, and the first connecting bottom plate 22 is fixed on the building roof 2, the two L-shaped connecting plates 21 are butted end to end with the two F-type connectors 41 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 connected to the plurality of first friction strips 2 3. Braided connection, i.e., the connection between 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 two first friction strips 23 adjacent to the first friction strip 23, forming a braided structure in which the second friction strip 24 is connected to a plurality of first friction strips 23, wherein the second friction strip 24 comprises a corrugated steel plate, the edges of which are provided with chamfers, the outer wall of which is provided with a high-friction rubber material layer, and the corrugated steel plate and the high-friction rubber material layer are connected by dense ribs or rivets to reduce the slippage between the corrugated steel plate and the high-friction rubber material layer; the first friction strip 23 comprises a metal plate, the edges of which are provided with chamfers, the outer wall of which is provided with a high-friction rubber material layer, and the metal plate and the high-friction rubber material layer are connected by dense ribs or rivets 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, and the connection between the connecting ring and the second friction strip 24 is coated with waterproof glue to prevent rainwater from entering the interior of the corrugated steel plate and the high-friction rubber layer, causing aging, cracking or damage to the interior of the high-friction rubber layer. The plurality of connecting rings are arranged along the length direction of the second friction strip 24, and a connecting hook is hooked inside each connecting ring. A U-shaped buckle is arranged at the opening position of the connecting hook, and an anti-slip plate is installed at the opening of the U-shaped buckle. The cooperation of the anti-slip plate and the U-shaped buckle can prevent the connecting hook from detaching from the connecting ring during an earthquake. A nut is screwed at the opening of the U-shaped buckle, and the U-shaped buckle of the anti-slip plate is prevented by the nut. One end of the first connecting rod 25 is connected to the connecting hook, and the extension direction of the first connecting rod 25 is consistent with the extension direction of the L-shaped connecting plate 21. In parallel, the other ends of all first connecting rods 25 are movably connected to a movable component, and two adjacent first connecting rods 25 are slidably connected to a flexible mounting frame. When the building is vibrated, the movable component repeatedly flips on the parapet 1, and the movable component pulls the first connecting rod 25, so that 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 rub against each other during the sliding process, and energy is dissipated by friction work; at the same time, the connection between the flexible mounting frame and the first connecting rod 25 reciprocates on the first connecting rod 25 to keep the flexible mounting frame stable, thereby weakening the impact of the earthquake on the photovoltaic panel 26 and improving the installation stability of the photovoltaic panel 26. ;

[0031] like Figure 1 to Figure 6As shown, the flexible mounting frame includes a second connecting rod 46, and connecting steel sleeves 33 are provided at both ends of the second connecting rod 46. The connecting steel sleeve 33 is slidably installed on the first connecting rod 25. Ball bearings are provided in the connecting steel sleeve 33, and the connecting steel sleeve 33 slides on the first connecting rod 25 through the ball bearings. When the second connecting rods 46 in two adjacent flexible mounting frames are installed on a first connecting rod 25, a connecting steel sleeve 33 is used for connection, so that the two adjacent flexible mounting frames form a whole. A plurality of mounting sleeves 47 are rotatably connected to the second connecting rod 46, and a bearing is installed between the mounting sleeve 47 and the second connecting rod 46, so that the mounting sleeve 47 rotates on the second connecting rod 46 through the bearing. One end of the connecting steel cable 27 is connected to the outer wall of each mounting sleeve 47, and the other end of the connecting steel cable 27 is connected to the third connecting rod 19, and the connecting steel cable 27 is connected to the third connecting rod 19 through a metal cable clamp. The third connecting rod 19 is parallel to the second connecting rod 46, and in the initial position, the vertical distance between the two and the building roof 2 is the same, so that the flexible mounting frame is in a horizontal state, and the end heads of both ends of the third connecting rod 19 are respectively vertically connected with support uprights 29, and the bottom end faces of the support uprights 29 are installed on the upper end face of the L-shaped connecting plate 21; the third connecting rod 19 is supported by the support uprights 29, and the photovoltaic panel 26 is installed between two adjacent connecting steel cables 27, and the photovoltaic panel 26 and the connecting steel cables 27 are connected by metal buckles. When the existing building is vibrated, the movable component pulls the first connecting rod 25. When the first connecting rod 25 moves, the connecting steel sleeve 33 slides on the first connecting rod 25, so that the seventh connecting rod 46 moves along the axial direction of the first connecting rod 25, and the mounting sleeve 47 rotates on the seventh connecting rod 46, so that the flexible mounting frame maintains the initial installation state, improves the installation stability of the photovoltaic panel 26, so that the photovoltaic panel 26 can work stably.

[0032] like Figure 1 to Figure 6As shown, a slide groove 28 is provided on the opposite side end surfaces of the two L-shaped connecting plates 21, and the slide groove 28 is opened along the length direction of the L-shaped connecting plate 21. A slider 36 is slidably installed in each slide groove 28, and a damper 37 is connected between the side of the slider 36 and one end of the slide groove 28. Two connecting clamps 38 are symmetrically provided on the outer wall of the slider 36. The end of the second friction strip 24 is fixedly connected between the two connecting clamps 38 by screws, and the second friction strip 24 is installed between the two L-shaped connecting plates 21. When the existing building is vibrated, the damper 37 is further assisted by the first friction strip 23 and the second friction strip 24 to dissipate the seismic energy. In this embodiment, when the existing building is not vibrated, the damper 37 should be in a slightly tensile, compressed or unstressed state. The damper 37 adopts a low-damping damper with a self-resetting function, such as a damper using an SMA shape memory alloy wire. When the existing building is subjected to an earthquake, the damper 37 should dissipate the earthquake energy as little 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.

[0033] A limit plate is also provided in the chute 28 to prevent the slider 36 from being too close to one end of the chute 28 and to prevent the slider 40 from slipping off the track plate 39 when earthquakes occur frequently, thereby causing the metal clamping plate 14 to slip off the U-shaped steel plate 11.

[0034] like Figure 1 , Figure 2 , Figure 4 , Figure 5 , Figure 7 , Fig.12 and Fig.13As shown, a movable connection mode between the first connecting rod 25 and the parapet 1 is: a hinge ball assembly 34 is arranged on the end head of the first connecting rod 25 close to the parapet 1, and a U-shaped steel plate 11 is sleeved on the parapet 1. The U-shaped steel plate 11 and the parapet 1 are connected by a fixing screw 18, that is, a first fixing hole is opened on the parapet 1, and a second fixing hole is opened on the outer wall of the U-shaped steel plate 11. When the U-shaped steel plate 11 is installed on the parapet 1, the first fixing hole is aligned with the second fixing hole, and the fixing screw 18 is inserted into the aligned second fixing hole and the first fixing hole. Fixing nuts are screwed on the end heads of both 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. In order to reduce the damage to the structure of the parapet 1 caused by opening multiple first fixing holes on the parapet 1 during the installation process, a U-shaped extension steel plate is arranged on the end head of the U-shaped steel plate 11, and the U-shaped extension steel plate is installed on On another parapet 1 connected to the parapet 1, the connection between the U-shaped extension steel plate and the U-shaped steel plate 11 is located at the corner position of the parapet, and the U-shaped extension steel plate and the parapet 1 are also fixed using a fixing screw 18. If a U-shaped extension steel plate is set at one end of the U-shaped steel plate 11, the U-shaped steel plate 11 and the U-shaped extension steel plate form a quasi-L-shaped structure. If U-shaped extension steel plates are respectively set at both end ends of the U-shaped steel plate 11, the U-shaped steel plate 11 and the two U-shaped extension steel plates form a quasi-U-shaped structure or a quasi-Z-shaped structure, thereby enhancing the connection reliability between the U-shaped steel plate 11 and the parapet 1, and preventing the U-shaped steel plate 11 from partially detaching from the parapet 1 during the process of the metal splint 14 repeatedly flipping around the U-shaped steel plate 11 during an earthquake. A movable component is installed on the side wall of the U-shaped steel plate 11, and a hinge ball component 34 is installed on the movable component. The connection between the first connecting rod 25 and the movable component can be rotated through the hinge ball component 34.

[0035] Another movable connection method between the first connecting rod 25 and the parapet 1 is: a connecting hole is set on the end of the first connecting rod 25 close to the parapet 1, and an axis is rotatably connected in the connecting hole. The two ends of the axis are respectively connected to fixed plates, and the fixed plates are fixed on the movable component. When the movable component is repeatedly flipped on the U-shaped steel plate 11, the axis rotates in the connecting hole, so that the connection between the first connecting rod 25 and the movable component rotates.

[0036] like Figure 1 , Figure 2 , Figure 4 , Figure 5 , Figure 7 , Fig.12 and Fig.13As shown, the movable component includes a metal clamp 14, which is movably clamped on the outside of the U-shaped steel plate 11. The metal clamp 14 is an M-shaped metal plate or a U-shaped plate with a closed end. An enlarged head 35 is provided at the end of the metal clamp 14. The outer wall of the enlarged head 35 is in contact with the side wall of the U-shaped steel plate 11. The enlarged head 35 facilitates the metal clamp 14 to repeatedly flip around the U-shaped steel plate 11. A sliding member is provided on the internal top end surface of the metal clamp 14, and one end of the fourth connecting rod 32 is slidably connected in the sliding member. 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 clamp 14 is limited by the sliding member to prevent the metal clamp 14 from detaching from the U-shaped steel plate 11 when earthquakes occur frequently. At the same time, the metal clamp 14 can be stably flipped repeatedly on the U-shaped steel plate 11, thereby improving the stability of the operation of the device.

[0037] like Figure 4 and Figure 8 As shown, the sliding member includes a track plate 39, the extension direction of the track plate 39 is perpendicular to the extension direction of the parapet 1, a slide rail is arranged on the bottom end surface of the track plate 39 along its extension direction, a slider 40 is slidably connected in the slide rail, and the slider 40 is fixed to the upper end of the fourth connecting rod 32. Through the sliding member, when the existing building is subjected to an earthquake, the metal splint 14 can be stably flipped repeatedly around the U-shaped steel plate 11.

[0038] like Figure 1 , Figure 2 , Figure 4 , Figure 5 , Figure 7 , Fig.12 and Fig.13As shown, a first counterweight is provided on the metal splint 14, and the first counterweight includes a first force-bearing support rod 20, which is vertically fixed to a side end face of the metal splint 14 away from the first connecting rod 25, and the first force-bearing support rod 20 is connected to the metal splint 14 by means of a snap or welding method, and a fifth connecting rod 15 is provided on the top end head of the first force-bearing support rod 20, and 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, and a sixth connecting rod 17 is provided on the outer wall of the fifth connecting rod 15, and the projection line of the fifth connecting rod 15 vertically projected on the upper end face of the metal splint 14 is perpendicular to the projection line of the sixth connecting rod 17 vertically projected on the upper end face of the metal splint 14, and a first counterweight ball 16 is provided on the end head of the sixth connecting rod 17 away from the fifth connecting rod 15. In this embodiment, the first counterweight ball 16 is a metal body with a smaller volume but a heavier weight; the outer wall of the sixth connecting rod 17 and the fifth An oblique strut 31 is arranged between the outer walls of the connecting rod 15, and the oblique strut 31 is used to increase the stability of the connection between the sixth connecting rod 17 and the fifth connecting rod 15. A second force-bearing support rod 30 is arranged on the end face of the metal splint 14 on one side opposite to the first connecting rod 25. The second force-bearing support rod 30 and the metal splint 14 are connected by snapping 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 arranged on the top of the second force-bearing support rod 30. The seventh connecting rod 12 and the fifth connecting rod 15 are parallel to each other. The seventh connecting rod 12 arranged on all the metal splints 14 on the same parapet 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 1 to be repeatedly flipped synchronously when subjected to seismic force, so that all the first connecting rods 25 have a synchronous movement trend.

[0039] like Fig.12 As shown, the first counterweight also includes an arc-shaped connecting rod 43, one end of which is fixed on the top end face of the metal splint 14, and the other end of the arc-shaped connecting rod 43 is opposite to the building roof 2. An elastic connecting member 44 is connected to the end of the arc-shaped connecting rod 43 opposite to the building roof 2, and a second counterweight ball 45 is connected to the elastic connecting member 44. The second counterweight ball 45 cooperates with the elastic connecting member 44 to increase the frequency of the metal splint 14 flipping around the U-shaped steel plate 11 during an earthquake, that is, the frequency of the second friction strip 24 repeatedly sliding along the extension direction of the multiple first friction strips 23 can be further increased, thereby enhancing the energy dissipation effect.

[0040] The present invention also proposes a method for using a photovoltaic and earthquake-resistant integrated device for an existing building, which is applied to the above-mentioned photovoltaic and earthquake-resistant integrated device for an existing building, and comprises the following steps: When the existing building is vibrated, the movable assembly flips back and forth on the parapet 1; The movable assembly pulls the first connecting rod 25, so that the other end of the first connecting rod 25 away from the child wall 1 moves back and forth between the two F-shaped connecting members 41; The first connecting rod 25 pulls the second friction strip 24 to slide repeatedly along the first friction strip 23; The second friction strip 24 and the first friction strip 23 rub against each other during the sliding process to dissipate energy; at the same time, the connection between the flexible mounting frame and the first connecting rod 25 reciprocates on the first connecting rod 25 to keep the flexible mounting frame stable.

[0041] Specifically, when the existing building is not vibrated, the first counterweight ball 16 and the second counterweight ball 45 make the top of the metal clamp plate 14 tilt toward the building roof 2, so as to keep the metal clamp plate 14 stable, and the damper 37 should be in a slightly tensile, compressed or unstressed state, and the photovoltaic panel 26 also maintains a stable state in the horizontal plane; When the existing building is vibrated, the metal clamping plate 14 installed on the U-shaped steel plate 11 in the movable assembly repeatedly flips on the parapet 1. At the same time, under the action of the first counterweight ball 16 and the second counterweight ball 45, the metal clamping plate 14 repeatedly flips at a higher frequency. At this time, the slider 40 slides in the slide rail on the track plate 39. During the repeated flipping process, the metal clamping plate 14 drives the first connecting rod 25, so that the other end of the first connecting rod 25 away from the child wall 1 moves back and forth between the two F-shaped connecting pieces 41. At the same time, the connecting steel sleeve 33 slides on the first connecting rod 25, so that the second connecting rod 46 slides between the two connecting steel cables 27. At this time, the mounting sleeve 47 rotates on the second connecting rod 46. The first connecting rod 25 drives the second friction strip 24 to slide repeatedly along the extension direction of the first friction strip 23, and the second friction strip 24 and the first friction strip 23 rub against 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 the two F-type connecting parts 41, the damper 37 is used to increase the power of the second friction strip 24 to restore its initial position, so that the second friction strip 24 can quickly return to its initial position, so that it is convenient to move along the extension direction of the first friction strip 23 again, so that the second friction strip 24 and the first friction strip 23 can frictionally dissipate energy while ensuring the installation stability of the photovoltaic panel 26.
