Description

Technical Field

[0001] The present invention relates to the technical field of photovoltaic power generation, and in particular to a diagonal bracing beam installation device for assembling a photovoltaic bracket. Background Art

[0002] Photovoltaic power generation is a technology that uses the photovoltaic effect of semiconductor interfaces to directly convert light energy into electrical energy. Photovoltaic power generation has been widely used in various regions.

[0003] Photovoltaic panels are one of the most important components in photovoltaic power generation. When installing related photovoltaic power generation components, it is necessary to adjust the installation method according to the actual conditions of each region, such as the best light direction, wind speed, wind direction, geological conditions, land slope, etc., which will affect the final installation method of the photovoltaic panels. For a single photovoltaic panel, when installing, it is usually necessary to first install several foundations on the ground, and then install columns of varying heights on the foundations, and then set up the brackets on the columns. Since the heights of the columns are different, the brackets are tilted, and then the photovoltaic panels can be installed on the brackets, and finally the diagonal bracing beams and other strengthening structures can be installed.

[0004] However, in some areas, the wind is strong. If the height of the photovoltaic panel is high, the photovoltaic panel will be greatly affected by the wind and it is easy to damage the photovoltaic panel in strong winds. Therefore, in such cases, it is usually possible to choose to lower the height of the photovoltaic panel and lower the angle between the photovoltaic panel and the ground. However, due to the large area of ​​the photovoltaic panel, if the height and angle of the photovoltaic panel are explained, the space between the photovoltaic panel and the ground will be very small. When installing structures such as diagonal bracing beams, it is difficult for workers to enter under the photovoltaic panel, and it is very inconvenient to operate even if they enter in time. In addition, since structures such as diagonal bracing beams are usually connected to the columns and brackets at both ends, and then connected with bolts instead of welding, there will be a lot of installation gaps after installation. When the photovoltaic panel is subjected to a large external force (mainly in strong winds), the photovoltaic panel will produce repeated tension / pressure on the bracket, column, diagonal bracing beam and other structures. Due to the existence of the installation gap, the photovoltaic panel and the bracket will vibrate at a certain frequency, which may damage the photovoltaic panel. Therefore, it is necessary to design a device that can better install the photovoltaic bracket. Summary of the invention

[0005] The object of the present invention is to provide a diagonal brace beam installation device for assembling a photovoltaic bracket, which can efficiently install the diagonal brace beam of the photovoltaic bracket without entering under the photovoltaic panel, and the photovoltaic bracket has better stability after installation.

[0006] The present invention is achieved through the following technical solutions: the diagonal brace beam installation device for assembling a photovoltaic bracket of the present invention comprises a pair of first columns, a pair of second columns, a bracket frame mounted on the upper ends of the first columns and the second columns, a photovoltaic panel mounted on the bracket frame, comprising a first connecting plate arranged on the lower side of the bracket frame, a connecting block hinged to the first connecting plate, a connecting hole opened on the connecting block, a second connecting plate connected to the side wall of the lower end of the first column, and a diagonal brace assembly for connecting the second connecting plate and the connecting block; the diagonal brace assembly comprises a first support tube, a second support tube, a connecting head arranged at one end of the first support tube close to the connecting block, a fixing block arranged at the side wall of one end of the first support tube away from the connecting head, and a screw threadedly connected to both the first support tube and the second support tube; the connecting head is threadedly connected to the connecting hole, and the second support tube is connected to the second connecting plate.

[0007] Furthermore, a first elongated through hole is provided in the middle of the screw rod, and the length direction of the first through hole is parallel to the axial direction of the screw rod.

[0008] Furthermore, the second supporting tube is connected to the second connecting plate by bolts.

[0009] Furthermore, it also includes an adjustment plate attached to the lower side wall of the second support tube, a second through hole opened at one end of the adjustment plate, a third through hole opened at the other end of the adjustment plate, a limiting tube opened at the upper side wall of the second support tube, a rotating shaft inserted in the limiting tube, an elliptical extrusion block connected to the rotating shaft at one end outside the limiting tube, and a pressure sensor arranged between the extrusion block and the fixed block; the bolt is arranged to pass through the second through hole; the rotating shaft is arranged to pass through the third through hole.

[0010] Furthermore, a fixing plate is provided at one end of the adjustment plate close to the third through hole, and the fixing plate is connected to the pressure sensor via a spring.

[0011] Furthermore, a first limiting hole is opened in the middle of the fixing block, and a first limiting rod is provided on a side of the pressure sensor close to the fixing block; the first limiting rod is inserted into the first limiting hole.

[0012] Furthermore, a second limiting hole is opened in the middle of the adjustment plate, a second limiting rod is opened on the lower side wall of the second support tube, and the second limiting rod is inserted into the second limiting hole.

[0013] Furthermore, an L-shaped handle is provided at one end of the extrusion block away from the rotating shaft.

[0014] The technical solution of the present invention has at least the following advantages and beneficial effects: the diagonal brace beam installation device for photovoltaic bracket assembly of the present invention rotates the connection block and the connection hole to a nearly horizontal position when installing the bracket frame, then screws the connector on the first support tube horizontally into the connection hole of the connection block, rotates the first support tube so that it faces the second connection plate, screws the screw into the first support tube, then connects the second support tube to the second connection plate, aligns the screw with the second support tube, and uses the fixed block to force the first support tube to push upward. During the process of pushing the first support tube upward, screw the screw into the second support tube to complete the installation. In this way, during the entire installation process, workers do not need to enter under the bracket frame, which is very suitable for installation in extremely narrow spaces. And before the first support tube and the second support tube are completely fixed, the first support tube will be subjected to an upward force, that is, prestress is applied in the first support tube and the second support tube in advance, which not only can make the contact of each connection part closer, but also can well solve the problem of the gap in the connection part, so that when the photovoltaic panel is subjected to external force (mainly strong wind), it will not produce large vibrations due to the gap problem in the connection part, which can reduce the looseness of the entire photovoltaic bracket and better protect the photovoltaic panel.

[0030] Example

[0031] The following is further described in conjunction with specific embodiments. Figure 1 -Attached Figure 8 As shown in the figure (the photovoltaic panel is not shown in the figure for the convenience of structural display), the photovoltaic bracket assembly diagonal brace beam installation device of this embodiment includes a pair of first columns 11, a pair of second columns 12, a bracket frame 13 mounted on the upper ends of the first columns 11 and the second columns 12, and a photovoltaic panel mounted on the bracket frame 13, including a first connecting plate 14 arranged at the lower side of the bracket frame 13, a connecting block 15 hinged to the first connecting plate 14, a connecting hole opened in the connecting block 15, and a second connecting plate 14 connected to the side wall of the lower end of the first column 11. A connecting plate 16, and a diagonal brace assembly 20 for connecting the second connecting plate and the connecting block 15; the diagonal brace assembly 20 includes a first supporting tube 21, a second supporting tube 22, a connecting head 23 provided at one end of the first supporting tube 21 close to the connecting block 15, a fixing block 26 provided at the side wall of the first supporting tube 21 away from the connecting head 23, and a screw 24 threadedly connected to both the first supporting tube 21 and the second supporting tube 22; the connecting head 23 is threadedly connected to the connecting hole, and the second supporting tube 22 is connected to the second connecting plate 16.

[0032] Specifically, when installing the support frame 13, the connecting block 15 and the connecting hole are rotated to a nearly horizontal position, and then the connecting head 23 on the first support tube 21 is screwed horizontally into the connecting hole of the connecting block 15 (as shown in the attached figure). Figure 2 Then, the first support tube 21 is rotated to face the second connecting plate 16, the screw 24 is screwed into the first support tube 21, and then the second support tube 22 is connected to the second connecting plate 16 (as shown in the attached figure). Figure 3As shown), align the screw 24 with the second support tube 22, and through the relay of the fixing block 26, push the first support tube 21 upward with force. During the process of pushing the first support tube 21 upward, screw the screw 24 into the second support tube 22 to complete the installation. In this way, during the entire installation process, workers do not need to enter under the bracket frame 13, which is very suitable for installation in extremely narrow spaces. And before the first support tube 21 and the second support tube 22 are completely fixed, the first support tube 21 will be subjected to an upward force, that is, prestress is applied to the first support tube 21 and the second support tube 22 in advance, which not only makes the contact of each connection part closer, but also can well solve the gap problem of the connection part, so that when the photovoltaic panel is subjected to external force (mainly strong wind), it will not produce large-scale vibration due to the gap problem of the connection part, which can reduce the looseness of the entire photovoltaic bracket and better protect the photovoltaic panel.

[0033] In this embodiment, a long first through hole 25 is provided in the middle of the screw rod 24, and the length direction of the first through hole 25 is parallel to the axial direction of the screw rod 24. Specifically, the first through hole 25 is used to assist in rotating the screw rod 24, and a labor-saving rod (such as a screwdriver, etc.) can be inserted into the first through hole 25, and then the screw rod 24 can be rotated more easily, so that the screw rod 24 can be screwed into the second support tube 22.

[0034] In this embodiment, the second support tube 22 is connected to the second connection plate 16 by bolts 17. Specifically, after the end of the second support tube 22 is inserted into the second connection plate 16, the bolts 17 are inserted and then the nuts are tightened.

[0035] In this embodiment, it also includes an adjustment plate 31 attached to the lower side wall of the second support tube 22, a second through hole 32 opened at one end of the adjustment plate 31, a third through hole 33 opened at the other end of the adjustment plate 31, a limiting tube 28 opened at the upper end side wall of the second support tube 22, a rotating shaft 39 inserted in the limiting tube 28, an elliptical extrusion block 38 connected to the end of the rotating shaft 39 located outside the limiting tube 28, and a pressure sensor 36 arranged between the extrusion block 38 and the fixed block 26; the bolt 17 is arranged to pass through the second through hole 32; the rotating shaft 39 is arranged to pass through the third through hole 33. Specifically, the adjusting plate 31 can assist in pushing the first support tube 21 upward. First, the adjusting plate 31 is attached to the lower side of the second support tube 22, and the screw 24 is passed through the first through hole 25. Then, the adjusting plate 31 is tightened with a nut, and the rotating shaft 39 is inserted into the limiting tube 28. The position of the pressure sensor 36 is adjusted so that it is stuck between the extrusion block 38 and the fixed block 26. Then, the extrusion block 38 can be slowly rotated by external force. Since the extrusion block 38 is elliptical, the extrusion block 38 will continuously squeeze the pressure sensor 36 during the process of rotating around the rotating shaft 39. The fixed block 26 is pushed by the pressure sensor 36, and the first support tube 21 is pushed upward. The required prestress can be better determined by the pressure sensor 36. When the specified pressure is reached, the extrusion block 38 is stopped from rotating, and the screw 24 is screwed into the second support tube 22. In addition, since the extrusion block 38 is connected to the second support tube 22, in the process of rotating the extrusion block 38, not only the first support tube 21 and the structure above it can be tightened, but also the second support tube 22 and the part below it can be tightened. After the operation is completed, the adjustment plate 31, the extrusion block 38, the pressure sensor 36 and other structures can be removed, wherein the pressure sensor 36 can use a relatively small flat pressure sensor 36. In addition, for different installation environments, when the gap between the first support tube 21 and the second support tube 22 is large, a larger extrusion block 38 can be replaced or a cushion block can be added. When the gap between the first support tube 21 and the second support tube 22 is small, a smaller extrusion block 38 can be replaced.

[0036] In this embodiment, a fixing sheet 34 is provided at one end of the adjustment plate 31 near the third through hole 33, and the fixing sheet 34 is connected to the pressure sensor 36 via a spring 35. Specifically, the pressure sensor 36 can be connected to the adjustment plate 31, and the spring 35 can make the pressure sensor 36 stick well to the fixing block 26, so that it will not slip off easily during operation, and there is no need to install the pressure sensor 36 additionally during use, which makes the operation more convenient.

[0037] In this embodiment, a first limiting hole 27 is provided in the middle of the fixing block 26, and a first limiting rod 37 is provided on a side of the pressure sensor 36 close to the fixing block 26; the first limiting rod 37 is inserted into the first limiting hole 27. Specifically, by inserting the first limiting rod 37 into the first limiting hole 27, displacement of the pressure sensor 36 can be avoided during the extrusion process.

[0038] In this embodiment, a second limiting hole 311 is provided in the middle of the adjustment plate 31, and a second limiting rod 29 is provided on the lower side wall of the second support tube 22, and the second limiting rod 29 is inserted into the second limiting hole 311. Specifically, on the fixed adjustment plate 31, the second limiting rod 29 is inserted into the second limiting hole 311, so that the adjustment plate 31 can be better positioned.

[0039] The end of the extrusion block 38 in this embodiment away from the rotating shaft 39 is provided with an L-shaped handle 310. Specifically, the handle 310 is a labor-saving rod, and a conventional wrench or the like can be directly used.

[0040] In summary, the photovoltaic bracket assembly diagonal brace beam installation device of this embodiment rotates the connection block 15 and the connection hole to a nearly horizontal position when installing the bracket frame 13, then screws the connector 23 on the first support tube 21 horizontally into the connection hole of the connection block 15, and then rotates the first support tube 21 to face the second connection plate 16, screws the screw 24 into the first support tube 21, and then connects the second support tube 22 to the second connection plate 16, aligns the screw 24 with the second support tube 22, and relays the first support tube 21 through the fixing block 26, and pushes the first support tube 21 upward with force. During the process of pushing the first support tube 21 upward, screw the screw 24 into the second support tube 22, and the installation is completed. In this way, during the entire installation process, workers do not need to enter the bottom of the bracket frame 13, which is very suitable for installation in extremely narrow spaces. And before the first support tube 21 and the second support tube 22 are completely fixed, the first support tube 21 will be subjected to an upward force, that is, prestress is applied in advance in the first support tube 21 and the second support tube 22, which not only can make the contact of each connection part closer, but also can well solve the problem of the gap in the connection part, so that when the photovoltaic panel is subjected to external force (mainly strong wind), it will not produce large vibrations due to the gap problem in the connection part, which can reduce the looseness of the entire photovoltaic bracket and better protect the photovoltaic panel.

For those skilled in the art, the present invention may have various modifications and variations.
