Description

Technical Field

[0001] The present invention relates to the technical field of photovoltaic power generation, and more particularly, to an installation device for a diagonal brace beam used in the assembly of a photovoltaic support. Background Art

[0002] Photovoltaic power generation is a technology that directly converts light energy into electrical energy by utilizing the photovoltaic effect at the semiconductor interface. 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 situation of each region, such as the best lighting direction, wind speed, wind direction, geological conditions, land slope, etc. These will all affect the final installation method of the photovoltaic panels. For a single photovoltaic panel, during installation, usually several foundations are first installed on the ground, and then columns with different heights are installed on the foundations. The bracket is erected on the columns. Since the heights of the columns are different, the bracket is inclined. Then the photovoltaic panel is installed on the bracket, and finally, strengthening structures such as diagonal brace beams are installed.

[0004] However, in some areas with strong winds, if the height of the photovoltaic panel is relatively high, the photovoltaic panel is greatly affected by the wind and is easily damaged in strong winds. Therefore, in such cases, it is usually possible to choose to reduce the height of the photovoltaic panel and the angle between the photovoltaic panel and the ground. However, since the area of the photovoltaic panel is relatively large, if the height and angle of the photovoltaic panel are both relatively low, the space between the photovoltaic panel and the ground will be very small. When installing structures such as diagonal brace beams, it is difficult for workers to enter under the photovoltaic panel, and even if they enter, it is very inconvenient to operate. And since structures such as diagonal brace beams usually connect the two ends to the columns and brackets respectively and then use bolts for connection instead of welding, there will be many installation gaps after installation. When the photovoltaic panel is subjected to a large external force (mainly strong wind weather), the photovoltaic panel will generate repeated tensile / compressive forces on structures such as brackets, columns, and diagonal brace beams. Due to the existence of installation gaps, 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 support. Summary of the Invention

[0005] The purpose of the present invention is to provide an installation device for a diagonal brace beam used in the assembly of a photovoltaic support, which can efficiently install the diagonal brace beam of the photovoltaic support without the need to enter under the photovoltaic panel, and the installed photovoltaic support has better stability.

[0006] The present invention is realized through the following technical solutions: The installation device for the diagonal bracing beam used in the assembly of the photovoltaic support of the present invention includes a pair of first columns, a pair of second columns, a support frame erected at the upper ends of the first columns and the second columns, and a photovoltaic panel erected on the support frame. It includes a first connecting plate provided on the lower side of the support frame, a connecting block hinged to the first connecting plate, a connecting hole opened in the connecting block, a second connecting plate connected to the side wall of the lower end of the first column, and a diagonal bracing assembly for connecting the second connecting plate and the connecting block; the diagonal bracing assembly includes a first support pipe, a second support pipe, a connecting head provided at one end of the first support pipe close to the connecting block, a fixing block provided on the side wall of the first support pipe away from the connecting head, and a screw rod threadedly connected to both the first support pipe and the second support pipe; the connecting head is threadedly connected to the connecting hole, and the second support pipe is connected to the second connecting plate.

[0007] Further, a long strip-shaped first through hole is opened 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] Further, the second support pipe and the second connecting plate are connected by bolts.

[0009] Further, it further includes an adjusting plate attached to the lower side wall of the second support pipe, a second through hole opened at one end of the adjusting plate, a third through hole opened at the other end of the adjusting plate, a limiting pipe opened on the upper side wall of the second support pipe, a rotating shaft inserted into the limiting pipe, an oval pressing block connected to the end of the rotating shaft outside the limiting pipe, and a pressure sensor provided between the pressing block and the fixing block; the bolt passes through the second through hole; the rotating shaft passes through the third through hole.

[0010] Further, a fixing piece is provided at the end of the adjusting plate close to the third through hole, and a spring is connected between the fixing piece and the pressure sensor.

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

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

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

[0014] The technical solution of the present invention has at least the following advantages and beneficial effects: For the diagonal brace beam installation device for assembling a photovoltaic bracket of the present invention, when installing the bracket frame, the connecting block and the connecting hole are rotated to a position close to horizontal, and then the connecting head on the first support pipe is horizontally screwed into the connecting hole of the connecting block. Then, the first support pipe is rotated so that it faces the second connecting plate, and the screw is screwed into the first support pipe. Then, the second support pipe is connected to the second connecting plate, the screw is aligned with the second support pipe, and by the relay of the fixing block, the first support pipe is forcefully pushed upward. During the upward pushing process of the first support pipe, the screw is screwed into the second support pipe, and the installation can be completed. In this way, during the entire installation process, workers do not need to enter below the bracket frame, which is very suitable for installation in extremely narrow spaces. And before completely fixing the first support pipe and the second support pipe, the first support pipe will receive an upward pushing force, that is, a prestress is applied to the first support pipe and the second support pipe in advance. This can not only make the contact of each connecting part closer, but also can well solve the problem of gaps at the connecting parts, so that when the photovoltaic panel is affected by external forces (mainly strong winds), large vibrations will not occur due to the gap problem at the connecting parts, which can reduce the loosening of the entire photovoltaic bracket and better protect the photovoltaic panel.

[0030] Embodiment

[0031] The following is further described in conjunction with specific embodiments. As shown in the attached Figure 1 - attached Figure 8 As shown (in the attached drawings, the photovoltaic panel is not shown for the convenience of showing the structure), the installation device for the inclined support beam for assembling the photovoltaic support of this embodiment includes a pair of first columns 11, a pair of second columns 12, a support frame 13 erected on the upper ends of the first column 11 and the second column 12, and a photovoltaic panel erected on the support frame 13. It includes a first connecting plate 14 provided on the lower side of the support frame 13, a connecting block 15 hinged to the first connecting plate 14, a connecting hole opened in the connecting block 15, a second connecting plate 16 connected to the side wall of the lower end of the first column 11, and a diagonal support assembly 20 for connecting the second connecting plate and the connecting block 15; the diagonal support assembly 20 includes a first support tube 21, a second support tube 22, a connecting head 23 provided at one end of the first support tube 21 close to the connecting block 15, a fixing block 26 provided on the side wall of the first support tube 21 away from the connecting head 23, and a screw 24 threadedly connected to both the first support tube 21 and the second support tube 22; the connecting head 23 is threadedly connected to the connecting hole, and the second support 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 position close to the horizontal, and then the connecting head 23 on the first support tube 21 is horizontally screwed into the connecting hole of the connecting block 15 (as shown in the attached Figure 2 drawing), 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 3As shown in the figure, align the screw rod 24 with the second support tube 22. Through the relay of the fixing block 26, forcefully push the first support tube 21 upwards. During the process of pushing the first support tube 21 upwards, screw the screw rod 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 below the support 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 pushing force, that is, prestress is applied to the first support tube 21 and the second support tube 22 in advance. This can not only make the contact of each connection part closer, but also well solve the gap problem at the connection part, so that when the photovoltaic panel is subjected to external forces (mainly strong winds), large vibrations will not occur due to the gap problem at the connection part, which can reduce the loosening of the entire photovoltaic support and better protect the photovoltaic panel.

[0033] In this embodiment, a long strip-shaped 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 function of the first through hole 25 is to assist in rotating the screw rod 24. 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 as to screw the screw rod 24 into the second support tube 22.

[0034] In this embodiment, the second support tube 22 and the second connecting plate 16 are connected by bolts 17. Specifically, after the end of the second support tube 22 is clamped into the second connecting plate 16, insert the bolt 17 and then tighten the nut.

[0035] In this embodiment, it further includes an adjusting plate 31 attached to the lower side wall of the second support pipe 22, a second through hole 32 opened at one end of the adjusting plate 31, a third through hole 33 opened at the other end of the adjusting plate 31, a limiting pipe 28 opened at the upper side wall of the second support pipe 22, a rotating shaft 39 inserted into the limiting pipe 28, an oval pressing block 38 connected to the outer end of the rotating shaft 39 outside the limiting pipe 28, and a pressure sensor 36 disposed between the pressing block 38 and the fixed block 26; a bolt 17 is disposed through the second through hole 32; the rotating shaft 39 is disposed through the third through hole 33. Specifically, the adjusting plate 31 can be used to assist in jacking up the first support pipe 21. First, the adjusting plate 31 is attached to the lower side of the second support pipe 22, and the screw rod 24 is passed through the first through hole 25. Then, the adjusting plate 31 is tightened with a nut. The rotating shaft 39 is inserted into the limiting pipe 28, and the position of the pressure sensor 36 is adjusted so that it is stuck between the pressing block 38 and the fixed block 26. Then, the pressing block 38 can be slowly rotated by an external force. Since the pressing block 38 is oval, during the process of the pressing block 38 rotating around the rotating shaft 39, it will continuously press the pressure sensor 36. The pressure sensor 36 is used to push the fixed block 26 and push the first support pipe 21 upward. Moreover, the required prestress magnitude can be better determined through the pressure sensor 36. When the specified pressure is reached, stop rotating the pressing block 38, and screw the screw rod 24 into the second support pipe 22. In addition, since the pressing block 38 is connected to the second support pipe 22, during the process of rotating the pressing block 38, not only can the first support pipe 21 and the structure above it be tightened, but also the second support pipe 22 and the part below it can be tightened. After the operation is completed, structures such as the adjusting plate 31, the pressing block 38, and the pressure sensor 36 can be removed. Among them, a relatively small flat pressure sensor 36 can be used for the pressure sensor 36. In addition, for different installation environments, when the gap between the first support pipe 21 and the second support pipe 22 is large, a pressing block 38 with a larger size can be replaced or a spacer can be added. When the gap between the first support pipe 21 and the second support pipe 22 is small, a pressing block 38 with a smaller size can be replaced.

[0036] One end of the adjusting plate 31 in this embodiment near the third through hole 33 is provided with a fixing piece 34, and the fixing piece 34 is connected to the pressure sensor 36 through a spring 35. Specifically, this can connect the pressure sensor 36 to the adjusting plate 31. The spring 35 can enable the pressure sensor 36 to be well attached to the fixed block 26 and will not easily slip during operation. When in use, there is no need to additionally install the pressure sensor 36, and the operation is more convenient.

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

[0038] In the middle of the adjusting plate 31 in this embodiment, a second limiting hole 311 is provided. On the lower side wall of the second support tube 22, a second limiting rod 29 is provided, and the second limiting rod 29 is inserted into the second limiting hole 311. Specifically, when fixing the adjusting plate 31 and inserting the second limiting rod 29 into the second limiting hole 311, the adjusting plate 31 can be better positioned.

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

[0040] In summary, for the diagonal bracing beam installation device for assembling the photovoltaic support in this embodiment, when installing the support frame 13, the connecting block 15 and the connecting hole are rotated to a position close to the horizontal. Then, the connecting head 23 on the first support tube 21 is horizontally screwed into the connecting hole of the connecting block 15, and then the first support tube 21 is rotated so that it faces the second connecting plate 16, and the screw 24 is screwed into the first support tube 21. Then, the second support tube 22 is connected to the second connecting plate 16, the screw 24 is aligned with the second support tube 22, and through the relay of the fixed block 26, the first support tube 21 is forcefully pushed upward. During the upward pushing process of the first support tube 21, the screw 24 is screwed into the second support tube 22, and the installation can be completed. In this way, during the entire installation process, workers do not need to enter below the support 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 receive an upward pushing force, that is, prestress is applied to the first support tube 21 and the second support tube 22 in advance. This can not only make the contact of each connecting part closer, but also can well solve the gap problem at the connecting part, so that when the photovoltaic panel is affected by external forces (mainly strong winds), large-amplitude vibrations will not occur due to the gap problem at the connecting part, the loosening of the entire photovoltaic support can be reduced, and the photovoltaic panel can be better protected.

[0041] The above are only the preferred embodiments of the present invention and are not used to limit the present invention. For those skilled in the art, various changes and modifications can be made to the present invention. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
