Abstract
Description
Technical Field
[0001] This utility model relates to the field of photovoltaic pillar technology, specifically to an H-type photovoltaic pillar support component. Background Technology
[0002] Photovoltaics (PV) is a technology that utilizes the photovoltaic effect of semiconductor materials to directly convert solar energy into electrical energy. A photovoltaic power generation system mainly consists of the following core components: Solar panels: Made of semiconductor materials such as monocrystalline silicon, polycrystalline silicon, or thin-film semiconductors, these panels are connected in series to form large-area modules responsible for capturing solar energy and converting it into direct current (DC). Controller: Manages the energy flow between the solar panels, batteries, and inverters, providing functions such as maximum power point tracking and overcharge / over-discharge protection. Inverter: Converts DC to alternating current (AC) to meet the power needs of household and industrial electrical equipment, and also provides the mounting system for the solar panels.
[0003] A photovoltaic (PV) support system consists of columns and brackets. The columns provide ground support, while the bracket system supports the solar panels. Currently, there are various column shapes, such as circular, U-shaped, square, and H-shaped. The main characteristic of an H-shaped column is a web with flanges on either side, its cross-section resembling the letter H, hence the name H-shaped. Currently, H-shaped columns have uniform dimensions (uniform cross-section). Besides the solar panels, PV supports are primarily subjected to horizontal wind loads after installation. The columns, as part of the support system, mainly function as bending members. Structural calculations often select the column material and cross-sectional dimensions based on the maximum bending moment at the bottom. However, in practical applications, the bending moment above the bottom gradually decreases. That is, there is a linear relationship between the bending moment and the distance from the ground: the bending moment is greater closer to the ground and smaller further away. Therefore, support columns with uniform cross-sections have significant material redundancy in the upper part. Therefore, when using metal components with uniform cross-sections to make support columns, there is a waste of metal material above the bottom of the column. When such support columns are applied to a photovoltaic support array, the large number of them undoubtedly increases the production cost significantly. Utility Model Content
[0004] To achieve the above objectives, this utility model specifically adopts the following technical solution: An H-shaped photovoltaic column support component includes an integrally formed and fixed web plate and two wing plates forming an H-shaped structure. An mounting plate is fixed to the top position of the side of the web plate that is offset from the wing plates. A lidar is installed at the bottom of the mounting plate. A reflector is installed at the bottom position of the web plate directly below the lidar. The lidar is oriented towards the reflector. Both the web plate and the wing plates are arranged in a trapezoidal structure that is narrower at the top and wider at the bottom.
[0005] Furthermore, the slope of the trapezoidal inclined planes of the web and flanges is 1°-5°. This varies depending on the design height and cross-sectional dimensions of the column, with the specific angle determined by the designed support strength of the column.
[0006] Furthermore, a base plate is fixed to the bottom of the web, and the bottom of the wing plate is also fixed to the base plate. Multiple reinforcing plates are fixed between the top of the base plate and the sides of the web and wing plate. Hinges are fixed to the top of the web and wing plate. The reinforcing plates increase the connection strength between the base plate and the web and wing plate, and the hinges provide the tilt adjustment function of the support system.
[0007] Furthermore, U-shaped buckles are snapped onto the bottom of the two wing plates, with tightening bolts connected to the U-shaped buckles. The ends of the tightening bolts abut against the wing plates. Threaded rods are fixed to the U-shaped buckles of the two wing plates, and sliding sleeves that slide along the threaded rods are fitted onto the threaded rods. The reflector is fixed to the top of the sliding sleeves, and threaded sleeves are threadedly connected to the threaded rods at both ends of the sliding sleeves. When the sliding sleeves slide on the threaded rods, the threaded sleeves are first loosened, the sliding sleeves are slid to the desired position, and then the threaded sleeves are tightened to abut against the sliding sleeves, thus fixing the sliding sleeves in place.
[0008] Furthermore, the threaded rod has a square cross-section with arc-shaped corners, and the thread is located at the four arc-shaped corners. The square structure prevents the sleeve from rotating on the threaded rod instead of sliding along it.
[0009] Furthermore, the inner side of the U-shaped buckle is grooved, and a rubber strip is fixed in the groove, with the rubber strip abutting against the surface of the wing plate. The rubber strip increases the friction between the U-shaped buckle and the wing plate, improving the stability of the U-shaped buckle on the wing plate.
[0010] Furthermore, a top seat is fixed to the top of the web and the wing plate. The bottom of the top seat has a pre-set H-shaped insertion port. The tops of the web and the wing plate are inserted into the insertion port. The top seat at the bottom of the insertion port is welded to the web and the wing plate. A hinge seat is installed on top of the top seat. The top seat increases the connection strength and stability between the hinge seat and the column.
[0011] Furthermore, a fixing plate is installed on the outer side of the wing plate away from the web plate near the top. Support plates are fixed to both ends of the fixing plate, and the support plates are welded to the wing plate. Two sleeves are provided between the fixing plate and the wing plate, and the sleeves are fixed to the fixing plate. Threaded holes are provided on the fixing plate and the sleeves. This does not compromise the structural strength of the entire column.
[0012] The beneficial effects of this utility model are as follows: 1. In this utility model, the web and wing plates constituting the column are trapezoidal structures that are narrower at the top and wider at the bottom, which conforms to the bending moment characteristics of the column decreasing from bottom to top. Under the premise of ensuring that the support strength of the column remains unchanged, the amount of material used for the column can be saved, thereby reducing the production cost. At the same time, by using laser radar in conjunction with the reflector, the deformation of the column can be detected by laser to ensure the safety of the photovoltaic array.
[0013] 2. In this utility model, the reflector plate can be adjusted in position by sliding the sliding sleeve on the threaded rod and by adjusting the U-shaped buckle on the wing plate to adapt to the lidar.
[0014] 3. In this utility model, the hinge seat is fixed to the column by a top seat. The top seat and the column are fixed by a combination of plug-in and welding, which can improve the fixing strength between the hinge seat and the column.
[0015] 4. The design of the fixing plate and sleeve on the middle wing plate of this utility model facilitates the fixing of the photovoltaic support system to the column, while eliminating the need to drill holes in the column and thus not compromising the overall structural strength of the column.

Detailed Implementation
[0018] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings.
[0019] This application provides an H-type photovoltaic column support component and offers the following technical solution, which will be discussed below. Figures 1-9 Please provide a detailed explanation: An H-shaped photovoltaic column support component includes a web plate 1 and two wing plates 2. The two wing plates 2 are integrally formed and fixed on both sides of the web plate 1. The cross-section of the two wing plates 2 and the web plate 1 is set in an H-shape. An L-shaped mounting plate 9 is welded and fixed to the top position of the side of the web plate 1 that is offset from the wing plates 2. A lidar 8 is installed at the bottom of the mounting plate 9 by bolts. A reflector 14 is installed at the bottom position of the web plate 1 directly below the lidar 8. The lidar 8 is set facing the reflector 14. Both the web plate 1 and the wing plate 2 are trapezoidal structures that are narrower at the top and wider at the bottom. The slope of the trapezoidal slope of the web plate 1 and the wing plate 2 is 1°-5°. The bottom of the web plate 1 is welded and fixed to the bottom plate 3, and the bottom of the wing plate 2 is also welded and fixed to the bottom plate 3. Multiple reinforcing plates 4 are also welded and fixed between the top of the bottom plate 3 and the sides of the web plate 1 and the wing plate 2. The top of the web plate 1 and the wing plate 2 are fixed with hinge seats 7.
[0020] When in use, the base plate 3 is supported on the ground or fixed to a pre-set cement column. The support system is hinged to the hinge seat 7. When supported, the web plate 1 and the wing plate 2 jointly bear the weight of the support system and the solar panels installed on the support system, and at the same time bear the wind load acting on the solar panels. When the wind load acts on the solar panels, the direction of the force is perpendicular or inclined to the load-bearing direction of the web plate 1 and the wing plate 2. At this time, the web plate 1 and the wing plate 2 also bear the bending resistance. Since the bending moment is larger closer to the ground and smaller further away from the ground, the trapezoidal structure of the web plate 1 and the wing plate 2, which is narrower at the top and wider at the bottom, has a bottom length and width that are significantly larger than the top. If the bending resistance design of the entire column is based on the web plate 1 and the wing plate 2 at the top, the wider bottom can improve the bending resistance of the entire column. If the bending resistance design of the entire column is based on the web plate 1 and the wing plate 2 at the bottom, the narrower top fits the linear bending moment of the column. Without reducing the bending resistance design, the amount of material used in the column is reduced. When applied to large photovoltaic arrays, the material savings are extremely considerable. Simultaneously, when in use, the lidar 8 emits a laser to the reflector 14. After the laser shines on the reflector 14, it is reflected. If the web plate 1 maintains its original shape and posture during installation, the laser reflected by the reflector 14 should be received by the lidar 8. If the web plate 1 deforms after installation due to load, gravity, or bending moment, and the relative position of the reflector 14 and the lidar 8 deforms, causing the laser to be unable to shine on the reflector 14, the lidar 8 will not be able to receive the reflected laser, or can only receive a weak laser reflected by the wing plate 2. According to the detection results of the lidar 8, if the reflected laser can still be received, it means that the web plate 1 is not deformed, or the deformation is still within the safe range. If the reflected laser is not received, or the reflected laser is too weak, it means that the web plate 1 is deformed and the deformation exceeds the safe range. Regularly turning on the lidar 8 can detect the deformation of the photovoltaic array's columns, promptly identify support risks, and then take timely measures to prevent the photovoltaic array from collapsing.
[0021] In some embodiments, a U-shaped buckle 10 is snapped onto the bottom of the two wing plates 2, and a tightening bolt 16 is threaded onto the U-shaped buckle 10. The end of the tightening bolt 16 abuts against the wing plate 2. A threaded rod 11 is welded and fixed onto the U-shaped buckle 10 of the two wing plates 2. The cross-section of the threaded rod 11 is square, with the four corners of the square set in an arc shape. The thread is set at the four corners of the arc shape. A sliding sleeve 12 is fitted onto the threaded rod 11 and slides along the threaded rod 11. The reflector plate 14 is welded and fixed to the top of the sliding sleeve 12. Threaded sleeves 13 are threaded onto the threaded rod 11 at both ends of the sliding sleeve 12.
[0022] First, install the lidar 8, then fix the U-shaped buckle 10 on the wing plate 2. Then turn on the lidar 8. Depending on the laser irradiation position, slide the sliding sleeve 12 along the threaded rod 11, or adjust the depth of the U-shaped buckle 10 on the wing plate 2 to adjust the position of the reflector 14, so that the reflector 14 moves to the laser irradiation position, ensuring that the laser can be received by the lidar 8 after being reflected on the reflector 14.
[0023] In some embodiments, the inner side of the U-shaped buckle 10 is slotted, and a rubber strip 15 is fixed in the slot by an adhesive. The rubber strip 15 abuts against the surface of the wing plate 2.
[0024] When the U-shaped buckle 10 is fastened onto the wing plate 2, the rubber strip 15 is pressed tightly against the surface of the wing plate 2. The friction between the rubber strip 15 and the wing plate 2 ensures that the U-shaped buckle 10 is securely fastened onto the wing plate 2. Then, the tightening bolt 16 is tightened to press the entire U-shaped buckle 10 and the wing plate 2 together to form a reliable fastening.
[0025] In some embodiments, a top seat 5 is welded and fixed to the top of the web plate 1 and the wing plate 2. The bottom of the top seat 5 is pre-set with an H-shaped socket 6. The top of the web plate 1 and the wing plate 2 are inserted into the socket 6. The top seat 5 at the bottom of the socket 6 is welded to the web plate 1 and the wing plate 2. The hinge seat 7 is installed on the top of the top seat 5 by bolts.
[0026] The web plate 1 and the wing plate 2 form a column. When the column is subjected to bending, the bending deformation at the top is restricted within the socket 6. The hinge seat 7 and the top seat 5 are installed. Unless the top seat 5 is detached from the column, the support system installed on the hinge seat 7 can still maintain a certain degree of stability. The top seat 5 and the column are simultaneously plugged in and welded. Compared with single welding or bolt fixing, plugging has a limiting effect and can improve the connection strength between the hinge seat 7 and the column.
[0027] In some embodiments, a fixing plate 17 is installed on the outer side of the wing plate 2 away from the web plate 1 near the top. Support plates 18 are integrally formed and fixed at both ends of the fixing plate 17. The support plates 18 are welded and fixed to the wing plate 2. Two sleeves 19 are provided between the fixing plate 17 and the wing plate 2. The sleeves 19 are welded and fixed to the fixing plate 17. Threaded holes 20 are provided on the fixing plate 17 and the sleeves 19.
[0028] After the support system is hinged to the hinge seat 7, the tilt angle of the support system can be adjusted, thereby adjusting the orientation angle of the solar panel. In order to maintain the stability of the support system, diagonal braces are used to fix the adjusted support system to the column. Currently, the connection between the diagonal braces and the column is mainly bolted, which requires drilling holes in the wing plate 2 and then bolts passing through the holes to fix the diagonal braces. This drilling reduces the overall strength of the column. However, by bolting the diagonal braces to the fixing plate 17 and welding the support plate 18 to the wing plate 2, the overall strength of the column is not compromised by drilling holes on the surface of the wing plate 2, while still meeting the bolt fixing requirements of the diagonal braces.

Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention.
