Description

Technical Field

[0001] This application relates to the technical field of photovoltaic brackets, and particularly to a column installation base for a photovoltaic bracket. Background Art

[0002] With the development of the photovoltaic industry, the application of photovoltaic brackets is becoming more and more widespread. In conventional designs, the columns of photovoltaic brackets are usually connected to the base by hinged column feet. Although the hinged column feet have a simple structure, they will cause one end of the column to swing around the hinged column foot as the rotation axis. Therefore, additional inter-column supports need to be set up to make the force and deformation of the bracket meet the specification requirements. However, the installation process of the inter-column supports is relatively complex and requires precise measurement, positioning, and installation operations, resulting in low overall installation efficiency. Summary of the Invention

[0003] In view of this, this application proposes a column installation base for a photovoltaic bracket, which is suitable for installing the column at the required position, including: a fixed bottom plate, a fixed connecting piece, and a locking part;

[0004] The main body of the fixed connecting piece is a hollow columnar structure and has an opening on the top surface. The fixed connecting piece is arranged on the top surface of the fixed bottom plate, and the longitudinal direction of the body of the fixed connecting piece is perpendicular to the plane where the fixed bottom plate is located;

[0005] The fixed connecting piece matches the column of the photovoltaic bracket. The column is suitable for being inserted into the cavity of the fixed connecting piece through the top surface opening of the fixed connecting piece, and the fixed connecting piece is connected to the column through the locking part;

[0006] There are more than two stiffening ribs between the outer side wall of the fixed connecting piece and the top surface of the fixed bottom plate, which are suitable for providing stable support for the fixed connecting piece.

[0007] In a possible implementation manner, the main body of the fixed connecting piece is a cuboid structure, and one side of it is an open structure.

[0008] In a possible implementation manner, there are six stiffening ribs; two stiffening ribs are arranged on each outer side wall of the fixed connecting piece.

[0009] In a possible implementation manner, the main body of the fixed bottom plate is a rectangular plate-like structure.

[0010] In a possible implementation manner, first installation holes are opened at the four corners of the fixed bottom plate. The first installation holes are oblong hole structures, which are suitable for installing the fixed bottom plate to the required position.

[0011] In one possible implementation, the locking portion includes matching bolts, nuts and a pad; the column is arranged between the pad and the fixed connector; the fixed connector is provided with a second mounting hole, the bolt passes through the second mounting hole of the fixed connector, the column and the pad in sequence, the nut is sleeved on the bolt and tightly attached to the side of the pad away from the column, and is suitable for locking the column on the fixed connector.

[0012] In a possible implementation, each side of the fixed connector is provided with more than two second mounting holes; and the more than two second mounting holes are arranged equidistantly along the length direction of the fixed connector.

[0013] In a possible implementation, there are more than two locking portions; the more than two locking portions are respectively located on each side of the fixed connection member.

[0014] Beneficial effects of this application

[0015] The column mounting base of the present application significantly improves the overall stability and rigidity of the photovoltaic bracket, and effectively prevents the column from swinging due to force. At the same time, the column mounting base of the present application can meet the regulatory requirements of force and deformation without the need for additional inter-column support for fixing, thereby reducing the dependence on inter-column support and installation costs, and improving the installation efficiency of the column.

[0016] The stiffening ribs connect the fixed connector and the fixed base plate, increasing the contact area and connection points between the two, and improving the connection strength and stability between the fixed connector and the fixed base plate. When the column is subjected to external force, the stiffening ribs can disperse the force borne by the fixed connector and transfer it evenly to the fixed base plate, effectively avoiding deformation of the fixed connector, improving the bearing capacity of the fixed connector, and extending the service life of the fixed connector.

[0017] The four corners of the fixed base plate are provided with first mounting holes. The first mounting holes with oblong hole structures allow for fine adjustment when the fixed base plate is installed at the installation position, thereby more accurately adjusting the position of the fixed base plate and ensuring accurate installation of the fixed base plate.

[0018] By opening a second mounting hole on the fixed connection member, the locking portion cooperates with the second mounting hole to simplify the installation process of the column and ensure the stability of the overall structure and the firmness of the connection.

[0029] A column installation base for a photovoltaic support, suitable for installing a column 500 at a required position, such as Figures 1 to 3 shown, including: a fixed bottom plate 100, a fixed connecting piece 200, and a locking part 300; the main body of the fixed connecting piece 200 is a hollow columnar structure with an opening on the top surface, the fixed connecting piece 200 is arranged on the top surface of the fixed bottom plate 100, and the longitudinal direction of the body length of the fixed connecting piece 200 is perpendicular to the plane where the fixed bottom plate 100 is located; the fixed connecting piece 200 is matched with the column 500 of the photovoltaic support, and the column 500 is suitable for being inserted into the cavity inside the fixed connecting piece 200 through the opening on the top surface of the fixed connecting piece 200, and the fixed connecting piece 200 is connected with the column 500 through the locking part 300; there are more than two stiffening ribs 400 between the outer side wall of the fixed connecting piece 200 and the top surface of the fixed bottom plate 100, suitable for providing stable support for the fixed connecting piece 200.

[0030] It should be noted here that the fixed bottom plate 100 is installed on the ground at the required position, and the fixed bottom plate 100 provides a stable support plane for the installation of the column 500. The hollow columnar structure of the fixed connecting piece 200 and the opening design on its top surface provide stable support for the column 500, enabling the column 500 to be conveniently inserted into the inside of the fixed connecting piece 200, making the installation process of the column 500 simpler and faster. The design that the fixed connecting piece 200 and the fixed bottom plate 100 are perpendicular to each other can make the gravity and external forces on the column 500 be transmitted more directly to the fixed bottom plate 100, reducing the sway and displacement of the column 500 in the horizontal direction, ensuring that the connection between the column 500 and the column installation base of the present application is more stable, improving the stability of the overall structure. The locking part 300 fixes the column 500 in the cavity of the fixed connecting piece 200. The cavity structure of the fixed connecting piece 200 and the locking part 300 together provide the necessary supporting force for the column 500, preventing the column 500 from loosening or slipping out of the cavity of the fixed connecting piece 200 during use, ensuring that the connection between the column 500 and the fixed connecting piece 200 is firm and reliable. Compared with the way of hinged column feet, the column installation base of the present application significantly improves the overall stability and stiffness of the photovoltaic support, effectively avoiding the swing of the column 500 due to force. At the same time, the column installation base of the present application can meet the specification requirements of force and deformation without additional installation of inter-column supports for fixation, reducing the dependence on inter-column supports and the installation cost, and improving the installation efficiency of the column 500.

[0031] Meanwhile, the fixed connecting member 200 provides a limiting space for the column 500, preventing the column 500 from swinging when subjected to external forces. Since the column 500 is inserted into the cavity of the fixed connecting member 200 and installed in the column mounting base of the present application through the locking portion 300, there is no direct connection between the column 500 and the fixed bottom plate 100. When the column 500 is subjected to external forces, the stress generated is absorbed and dispersed by the fixed connecting member 200. The cooperation between the fixed connecting member 200 and the fixed bottom plate 100 ensures the stability and durability of the column 500.

[0032] The stiffening rib 400 connects the fixed connecting member 200 and the fixed bottom plate 100, increasing the contact area and connection points between the two, improving the connection strength and stability between the fixed connecting member 200 and the fixed bottom plate 100. When the column 500 is subjected to external forces, the stiffening rib 400 can disperse the force borne by the fixed connecting member 200 and evenly transfer it to the fixed bottom plate 100, effectively preventing the fixed connecting member 200 from deforming, improving the load-bearing capacity of the fixed connecting member 200, and extending the service life of the fixed connecting member 200.

[0033] Furthermore, the fixed bottom plate 100, the fixed connecting member 200, and the stiffening rib 400 are connected by welding or integrally formed. The welding method or the integrally formed method can ensure the tight combination between the fixed bottom plate 100, the fixed connecting member 200, and the stiffening rib 400, thereby enhancing the strength and stiffness of the overall structure. The welding method or the integrally formed design effectively reduces the on-site workload and improves the overall construction efficiency.

[0034] In a possible implementation manner, the main body of the fixed connecting member 200 is in a cuboid structure, and one side of the fixed connecting member 200 adjacent to the column mounting base is an open structure. It should be noted here that the fixed connecting member 200 with a cuboid structure has good stability and is suitable for providing stable support for the column 500, enabling the fixed connecting member 200 to withstand and transmit forces from all directions. The open structure on one side of the fixed connecting member 200 allows the column 500 to be more easily inserted into the cavity of the fixed connecting component when connecting with the column 500, and at the same time facilitates the locking portion 300 to fix the column 500 in the cavity of the fixed connecting member 200.

[0035] Preferably, the value range of the length of the fixed connecting member 200 is: not less than 200 mm.

[0036] In a possible implementation manner, as Figure 1As shown, there are six stiffeners 400; two stiffeners 400 are provided on each outer side wall of the fixed connecting member 200. It should be noted here that multiple stiffeners 400 can effectively disperse and transfer stress, thereby reducing stress concentration, avoiding deformation of the fixed connecting member 200, ensuring the stability of the fixed connecting member 200. Two stiffeners 400 are provided on each outer side wall of the fixed connecting member 200, so that the stress can be evenly distributed when the fixed connecting member 200 is stressed, avoiding damage caused by excessive local stress.

[0037] Furthermore, the main body of the stiffener 400 is in the shape of a rectangular plate, so as to ensure that the stress received by the fixed connecting member 200 is effectively dispersed and transferred through the stiffener 400, extending the service life of the fixed connecting member 400. Preferably, the height of the stiffener 400 is 80 mm, and the width of the stiffener 400 is 40 mm.

[0038] Furthermore, a preset distance is provided between the two stiffeners 400 on each outer side wall of the fixed connecting member 200. By reasonably setting the two stiffeners 400 and the preset distance therebetween, the stress can be dispersed to a wider area, reducing stress concentration and improving the overall load-bearing capacity and service life of the column mounting base of the present application.

[0039] In a possible implementation manner, as Figure 1 shown, the main body of the fixed bottom plate 100 is in the shape of a rectangular plate. It should be noted here that the fixed bottom plate 100 with a rectangular plate structure has good stability, can evenly disperse the loads from the fixed connecting member 200 and the column 500, and reduce stress concentration.

[0040] In a possible implementation manner, as Figure 1As shown, first mounting holes 110 are provided at the four corners of the fixed base plate 100. The first mounting holes 110 are in the form of an oblong hole structure, which is suitable for installing the fixed base plate 100 to the desired position. It should be noted here that the fixed base plate 100 is fixed to the position to be installed by four fastening bolts. There are four first mounting holes 110, which are centrally symmetrically arranged on the fixed base plate 100, and the length directions of each two adjacent first mounting holes 110 are perpendicular to each other. The mutually perpendicular first mounting holes 110 can make the mounting base of the present application be adjusted in two vertical directions respectively, to ensure that the fixed base plate 100 can be accurately and firmly installed in the position to be installed, wherein two fastening bolts respectively penetrate through a pair of first mounting holes 110 at diagonally opposite corners of the fixed base plate 100 and fix them to the position to be installed. After the base moves around the fastening bolts to adjust the relative position of the fixed base plate 100 and the position to be installed, the fixed base plate 100 is fixed for the first time, and the other two fastening bolts respectively penetrate the first mounting holes 110 at another pair of diagonally opposite corners of the fixed base plate 100 and the position to be installed to fix the fixed base plate 100 for a second time, thereby firmly installing the fixed base plate 100 at the position to be installed. The design of the oblong hole structure allows fine-tuning of the fixed base plate 100 when it is installed at the position to be installed, so that the position of the fixed base plate 100 can be adjusted more accurately, ensuring the accurate installation of the fixed base plate 100.

[0041] Preferably, the gap between the width of the first mounting hole 110 and the diameter of the fastening bolt is 2 mm. The 2 mm gap provides more room for the mounting bolt to move, so that the mounting position can be easily fine-tuned during the installation process, thereby ensuring the accuracy of the mounting position of the fixed base plate 100.

[0042] In one possible implementation, Figures 1 to 3 As shown, the locking portion 300 includes matching bolts 310, nuts 320 and a pad 330; the pad 330 and the fixed connector 200 are respectively located on the inner and outer sides of the column 500, and the fixed connector 200 is provided with a second mounting hole 210. The bolt 310 passes through the second mounting hole 210 of the fixed connector 200, the column 500 and the pad 330 in sequence. The nut 320 is sleeved on the bolt 310 and is tightly attached to the side of the pad 330 away from the column 500, which is suitable for locking the column 500 on the fixed connector 200.

[0043] It should be noted here that if Figure 2 , Figure 3 As shown, the second mounting hole 210 is an oblong hole structure and extends along the length direction of the fixed connection member 200. Figure 1As shown, the pad 330 is closely fitted with the side wall of the column 500 and is located on the side away from the fixed connector 200. The pad 330 is suitable for increasing the contact area between the bolt 310 and the column 500, effectively dispersing the pressure generated between the bolt 310 and the nut 320. The bolt 310 sequentially passes through the second mounting hole 210, the column 500 and the pad 330 are connected with the nut 320, and the nut 320 is sleeved on the bolt 310 and closely attached to the side of the pad 330 away from the column 500. The bolt 310 is inserted into the second mounting hole 210, and the column 500 and the pad 330 are connected with the nut 320. The combination of the screw 300 and the nut 320 provides a strong fastening force for the column 500 and the fixed connector 200. By screwing the nut 320, the nut 320 moves along the axial direction of the bolt 310 to achieve clamping between the column 500, the fixed connector 200 and the pad 330, thereby preventing the bolt 310 from loosening due to vibration or external force. The locking portion 300 cooperates with the second mounting hole 210 to simplify the installation process of the column 500 and ensure the stability of the overall structure and the firmness of the connection.

[0044] Furthermore, more than two locking parts 300 are provided; the more than two locking parts 300 are respectively located on each side of the fixed connector 200. It should be noted here that by providing more than two locking parts 300 on each side of the fixed connector 200, multi-point locking can be achieved, thereby ensuring the stability of the connection between the column 500 and the fixed connector 200. When the fixed connector 200 is subjected to external force, the multi-point distribution design can more effectively resist deformation and loosening.

[0045] In one possible implementation, Figure 2 , Figure 3 As shown, each side of the fixed connector 200 is provided with more than two second mounting holes 210; and the more than two second mounting holes 210 are arranged equidistantly along the length direction of the fixed connector 200. It should be noted here that the multiple second mounting holes 210 provide more connection options, and suitable mounting holes can be selected for connection according to actual needs, thereby improving the connection precision and accuracy between the column 500 and the fixed connector 200. Through the multiple equidistantly arranged second mounting holes 210, the force on the connector can be dispersed to more points, avoiding damage or deformation caused by excessive force on a single point.

Many modifications and changes will be apparent to those of ordinary skill in the art without departing from the scope and spirit of the described embodiments.
