Description

Technical Field

[0001] The utility model relates to the technical field of photovoltaic, in particular to a structure for stable support at the end of a flexible photovoltaic system. Background Technique

[0002] A flexible photovoltaic support is a new type of photovoltaic support, which has the characteristics of simple structure, less material use, light self-weight, large span, etc. Therefore, it can be suitable for various environments such as mountains and wastelands. The flexible photovoltaic support solution is to change the rigid purlin into a steel strand to form a flexible cable structure. By applying prestress to the stay cable, it has a certain stiffness, so as to install photovoltaic modules.

[0003] At present, most end supports of flexible photovoltaic systems are not convenient for on-site installation. Coupled with the large span of the support, there will be multiple support steel frames in the middle to form a middle support for the main cable to pass through. At the same time, the end support plays the role of connecting the main cable and the stay cable. The steel strand will generate a large unbalanced horizontal force on the top of the support, resulting in insufficient structural stability of the end support. At the same time, the weather conditions in different regions are different, and the wind loads generated in some areas with larger wind speeds are larger. When the end support is in use, there is a risk of excessive local stress, which will reduce the durability and stability of the support. Therefore, a structure for stable support at the end of a flexible photovoltaic system is proposed to solve the problems mentioned above. Content of the Utility Model

Coupled with the large span of the support, there will be multiple support steel frames in the middle to form a middle support for the main cable to pass through. At the same time, the end support plays the role of connecting the main cable and the stay cable. The steel strand will generate a large unbalanced horizontal force on the top of the support, resulting in insufficient structural stability of the end support. At the same time, the weather conditions in different regions are different, and the wind loads generated in some areas with larger wind speeds are larger. When the end support is in use, there is a risk of excessive local stress, which will reduce the durability and stability of the support.

[0005] To achieve the above purposes, the technical solution adopted by the utility model is as follows:

[0006] A structure for stable support at the end of a flexible photovoltaic system, including a column assembly, a crossbeam assembly is arranged at the upper end of the column assembly, a connection assembly is arranged on the outer surface of the column assembly, and a diagonal brace assembly is arranged at one end of the connection assembly;

[0007] Among them, the column assembly includes two column bases. The upper end of the column base is fixedly connected with a column body. The inner side of the column body is fixedly connected with a support rod. Two reinforcing rods are fixedly connected between the support rod and the column body. A triangular structure is formed between the reinforcing rod, the column base and the support rod. The upper ends of the column body and the reinforcing rod are both fixedly connected with a connecting seat. The upper end of the connecting seat is fixedly connected with a positioning column.

By arranging a support rod and a reinforcing rod between the column body and the crossbeam main body to form a triangular structure for auxiliary support of the column body and the crossbeam main body, the support rod and the reinforcing rod convert the horizontal force distributed on the bracket into an axial force along the rod, thereby reducing the influence of the bending moment and the unbalanced horizontal force on the bracket. At the same time, the triangular structure can evenly distribute the load, enhance the overall stiffness of the structure, and reduce the risk of deformation and possible instability.

By adjusting the inclination angle of the stay rod, the resistance of the support structure to external forces can be improved, the overall stability can be enhanced, so that the support can cope with the wind loads under various weather conditions, the applicability of the support is improved, and at the same time, it helps to reduce the influence of wind loads on the durability and stability of the support, thereby extending the service life of the support and the photovoltaic system.

[0015] In this solution, the column component, the crossbeam component and the stay component all adopt modular design and can be disassembled independently, which is convenient for maintenance and replacement. At the same time, the modular design is convenient for transporting and installing the support. Description of the Drawings

[0026] The following description is used to disclose the present utility model so that those skilled in the art can implement the present utility model. The preferred embodiments in the following description are only examples, and other obvious variations can be conceived by those skilled in the art.

[0027] Referring to Figure 1 , Figure 2 and Figure 3 shown in the figures, a structure for stabilizing the end support of a flexible photovoltaic system includes a column assembly 1, a crossbeam assembly 2 is arranged at the upper end of the column assembly 1, a connecting assembly 105 is arranged on the outer surface of the column assembly 1, and an inclined strut assembly 3 is arranged at one end of the connecting assembly 105;

[0028] Among them, the column assembly 1 includes two column bases 101, a column body 102 is fixedly connected to the upper end of the column base 101, a support rod 103 is fixedly connected to the inner side of the column body 102, two reinforcing rods 104 are fixedly connected between the support rod 103 and the column body 102, and a triangular structure is formed between the reinforcing rod 104 and the column base 101 and the support rod 103.

[0029] Furthermore, the crossbeam assembly 2 includes a crossbeam main body 201 movably connected to the upper end of the positioning column 107. A plurality of anchors 202 are arranged at the upper end of the crossbeam main body 201. Positioning grooves 203 are opened at corresponding positions on the lower end of the crossbeam main body 201 and the positioning column 107. The positioning column 107 is inserted into the interior of the positioning groove 203. Four evenly distributed connecting holes 204 are opened on the lower end of the crossbeam main body 201 outside the positioning groove 203. Through holes are penetrated at corresponding positions on the upper end of the connecting seat 106 and the reinforcing rod 104, and expansion screws 6 are threadedly connected inside the through holes and the connecting holes 204.

[0030] Furthermore, a triangular structure can be formed by the support rod 103 and the reinforcing rod 104 to assist in supporting the column body 102 and the crossbeam main body 201. The support rod 103 and the reinforcing rod 104 convert the horizontal forces distributed on the bracket into axial forces along the rods, thereby reducing the influence of the bending moment and the unbalanced horizontal force on the bracket. At the same time, the triangular structure can evenly distribute the load, enhance the overall stiffness of the structure, and reduce the risk of deformation and possible instability.

[0031] Furthermore, the design of the positioning groove 203 and the positioning column 107 can perform preliminary positioning and fixing during the installation of the crossbeam main body 201, facilitating the docking of the crossbeam main body 201 with the column body 102, thereby reducing the installation difficulty.

[0032] Referring to Figure 1 , Figure 4 and Figure 5As shown in the figure, the connecting component 105 includes a fixed frame body 1051 fixedly connected to the outer surface of the column body 102. First sliding grooves 1052 are formed at both the left and right ends of the fixed frame body 1051. First fixing holes 1053 are formed through the interiors of the first sliding grooves 1052. A first sliding seat 1054 is slidably connected inside the first sliding grooves 1052. A second fixing hole 1055 having the same size as the first fixing hole 1053 is formed through the left side of the first sliding seat 1054. Two first fixing seats 1056 are fixedly connected to the end of the first sliding seat 1054 away from the fixed frame body 1051.

[0033] Furthermore, the bracing component 3 includes a bracing base 301. An adjusting seat 302 is fixedly connected to the upper end of the bracing base 301. Second sliding grooves 303 are formed on both the left and right sides of the adjusting seat 302. Fourth through holes 304 are formed through the interiors of the second sliding grooves 303. A second sliding seat 305 is slidably connected inside the adjusting seat 302. A fifth through hole 306 having the same size as the fourth through hole 304 is formed through the left side of the second sliding seat 305. Two second fixing seats 307 are fixedly connected to the upper end of the second sliding seat 305. A bracing rod 308 is rotatably connected between the two second fixing seats 307. The other end of the bracing rod 308 is rotatably connected between the two first fixing seats 1056 through a pin.

[0034] Furthermore, the bracing rod 308 plays an auxiliary supporting role for the column body 102, which can improve the stability of the column body 102 during use. At the same time, by sliding the second sliding seat 305 and the first sliding seat 1054 along the second sliding groove 303 and the first sliding groove 1052, the supporting angle of the bracing rod 308 can be adjusted. The supporting angle of the bracing rod 308 determines how to decompose the wind load acting on the bracket into axial forces. Adjusting the bracing rod 308 to the optimal supporting angle according to the use environment can more effectively decompose the load into forces along the bracing direction, thereby better transmitting the load to the supporting point, making the wind load evenly distributed, reducing the local stress concentration caused by uneven load, and improving the stability of the overall structure.

[0035] Furthermore, fixing pins 4 are inserted into the interiors of the second fixing hole 1055 and the first fixing hole 1053, and the interiors of the fifth through hole 306 and the fourth through hole 304. One end of the fixing pin 4 is threadedly connected with a nut 5. By inserting the fixing pin 4 into the interiors of the second fixing hole 1055 and the first fixing hole 1053, and the interiors of the second sliding seat 305 and the fourth through hole 304 and using the nut 5 to fasten the fixing pin 4, the positions of the first sliding seat 1054 and the second sliding seat 305 can be fixed.

[0036] Working principle: When in use, first install the column base 101 and the brace base 301 at the pre-measured and marked positions. Then align the four positioning slots 203 at the lower end of the crossbeam main body 201 with the four positioning posts 107 and insert the positioning posts 107 into the positioning slots 203. Then install the expansion screws 6 in the through holes and connection holes 204 of the connection seat 106 to connect and fix the crossbeam main body 201 and the column body 102. Then install one end of the brace rod 308 away from the brace base 301 between the two first fixing seats 1056 through a pin shaft. Then adjust the support angle of the brace rod 308 by sliding the second sliding seat 305 and the first sliding seat 1054 along the second sliding groove 303 and the first sliding groove 1052 according to the local climate environment. When the brace rod 308 is adjusted to an appropriate support angle, insert the two fixing pins 4 into the interiors of the second fixing hole 1055 and the first fixing hole 1053 as well as the interiors of the fifth through hole 306 and the fourth through hole 304 and fix them with nuts 5 to complete the installation of the end bracket. The triangular structure formed by the support rod 103 and the reinforcing rod 104 can assist in supporting the column body 102 and the crossbeam main body 201, can convert the horizontal force distributed on the bracket into the axial force along the rod, thereby reducing the influence of the bending moment and the unbalanced horizontal force on the bracket. At the same time, the triangular structure can evenly distribute the load, enhance the overall stiffness of the structure, and reduce the risk of deformation and possible instability.
