Description

Technical Field

[0001] This utility model relates to a flexible tracking bracket end inclined tension system, belonging to the field of photovoltaic bracket technology. Background Technology

[0002] Flexible photovoltaic (PV) brackets are support frames used in solar power plants to support PV modules. Flexible PV brackets include end columns, middle columns, load-bearing cables, and wind-resistant structures. The end columns are located at the ends of the flexible PV brackets and are connected to the ground foundation through a cable-stayed system. Their main function is to constrain the two ends of the load-bearing cables.

[0003] As an upgraded structure of flexible photovoltaic (PV) brackets, flexible tracking brackets use a reducer to drive the end beam, which in turn drives the load-bearing cable and PV modules to rotate with the sun, thereby increasing power generation. In existing technologies, the cable-stayed systems of flexible tracking brackets mostly adopt the same structure as those of flexible PV brackets: one end is connected to the end column via steel strand or precision-rolled threaded steel, and the other end is connected to the ground foundation. For traditional flexible brackets, the top beam is fixedly connected to the top of the end column. After the PV modules are installed on the load-bearing cable, the beam mainly bears the prestress applied by the load-bearing cable and the weight of the PV modules. However, for flexible tracking brackets, the reducer, directly mounted on the beam, needs to overcome some of the prestress of the load-bearing cable when driving the beam to rotate. Under various combined operating conditions, the end beam will generate significant axial pressure and shear force on the reducer. Traditional cable-stayed systems can only reduce the downward pressure on the end column; long-term load will cause significant wear on the reducer, reducing its service life and posing a significant safety hazard.

[0004] To address the aforementioned issues, this application proposes a flexible tracking bracket end-cable system. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the existing defects and provide a flexible tracking bracket end inclined tension system. By using inclined tension components in two directions in conjunction with inclined pressure rods, the stress at the reducer is effectively reduced and the service life of the reducer is improved, which can effectively solve the problems in the background art.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: A flexible tracking bracket end inclined bracing system is installed on an end column, including an inclined pressure bar, an end crossbeam, a first inclined bracing assembly, and a second inclined bracing assembly. The inclined pressure bar is installed at the bottom of the end column and is disposed between the first inclined bracing assembly and the second inclined bracing assembly. The first diagonal bracing assembly is used to connect the diagonal compression bar and the end crossbeam. The first diagonal bracing assembly includes a first diagonal brace made of steel strand and a connector. The diagonal compression bar is connected to the first diagonal brace through the connector. The two ends of the first diagonal brace are connected to the end crossbeam and the middle part is connected to the connector. The second diagonal bracing assembly is used to connect the diagonal compression bar to the ground foundation. The second diagonal bracing assembly includes at least one second diagonal brace, and the upper and lower ends of the second diagonal brace are respectively connected to the diagonal compression bar and the ground foundation.

[0007] As a further improvement of this utility model, a mounting plate is provided on the top of the inclined pressure bar, and a mounting seat is fixedly provided on the top of the mounting plate. The connecting piece is connected to the mounting plate through the mounting seat.

[0008] As a further improvement of this utility model, the connecting member is configured as an arc-shaped plate, and the first inclined tie member is wrapped around the connecting member; Alternatively, the connector may be configured as a metal sleeve, with the first diagonal brace sleeved inside the connector.

[0009] As a further improvement of this utility model, the connecting member is fixedly connected to the mounting base by a screw.

[0010] As a further improvement of this utility model, a bearing is installed inside the mounting base, a rotating shaft is installed on the bearing, and the connecting piece is fixedly connected to the rotating shaft.

[0011] As a further improvement of this utility model, the first diagonal brace is connected to the end crossbeam by a first U-bolt.

[0012] As a further improvement of this utility model, the first diagonal brace is anchored to the end crossbeam via a first anchor.

[0013] As a further improvement of this utility model, a protective sleeve is provided through the end crossbeam, and a flared mouth is provided at the end of the protective sleeve near the inclined pressure bar. The end of the first inclined tie member passes through the protective sleeve and is anchored to the end crossbeam through the first anchor.

[0014] As a further improvement of this utility model, the second inclined tie is made of steel strand or finely rolled threaded steel, the top of the second inclined tie is connected to the mounting plate by a second U-bolt, and the bottom of the second inclined tie is connected to the ground foundation by a third U-bolt.

[0015] As a further improvement of this utility model, a drive motor is also fixedly installed on the top of the end column, the drive motor is rotatably connected to the end crossbeam, and a load-bearing cable is anchored to the end crossbeam by a second anchor.

[0016] The beneficial effects of this utility model are as follows: Compared with the existing inclined cable systems, which are mostly designed with the top of the steel strand connected to the column, the first inclined cable assembly in this application can move synchronously with the rotation of the end beam while providing a tension force opposite to the tension force of the load-bearing cable. Together with the inclined pressure bar and the inclined cable assembly, it forms a reasonably force-transmitting inclined cable structure system. Through the inclined cable system composed of the first inclined cable assembly, the inclined pressure bar and the second inclined cable assembly, the force on the end beam is effectively distributed and transmitted, and the load on the reducer is effectively reduced.

[0025] like Figures 1-4 As shown, a flexible tracking bracket end inclined bracing system is installed on the end column 1, including an inclined pressure rod 2, an end crossbeam 3, a first inclined bracing assembly, and a second inclined bracing assembly. The inclined pressure rod 2 is installed at the bottom of the end column 1 and is located between the first inclined bracing assembly and the second inclined bracing assembly. The first inclined bracing assembly is used to connect the inclined pressure rod 2 and the end crossbeam 3, and the second inclined bracing assembly is used to connect the inclined pressure rod 2 and the ground foundation. The first inclined tie assembly includes a first inclined tie member 4 configured as steel strand and a connector 43. The inclined pressure bar 2 is connected to the first inclined tie member 4 through the connector 43. The two ends of the first inclined tie member 4 are connected to the end crossbeam 3 and the middle part is connected to the connector 43. The second inclined tie assembly includes at least one second inclined tie member 5, with the upper and lower ends of the second inclined tie member 5 connected to the inclined pressure bar 2 and the ground foundation, respectively.

[0026] Ground foundation can be such as Figure 1The strip concrete foundation 54 shown has a foundation connecting seat 53 fixedly installed on it. The second diagonal tie 5 is connected to the foundation connecting seat 53 on the strip concrete foundation 54 by a third U-bolt 52. The ground foundation can also be set as an anchor foundation, which can be selected according to the geological environment of the project site.

[0027] Compared to the existing inclined cable system that directly connects the end column 1 to the ground foundation via steel strands, the first inclined cable 4 connects the end beam 3 to the inclined pressure bar 2. When the end beam 3 rotates, the first inclined cable 4 can move synchronously, effectively reducing the load acting on the end beam 3. The second inclined cable 5 connects the inclined pressure bar 2 to the ground foundation, transferring part of the load on the inclined pressure bar 2 to the ground foundation, thus improving the structural stability of the overall flexible tracking support.

[0028] In some alternative embodiments, the top of the inclined pressure bar 2 is provided with a mounting plate 41, the top of the mounting plate 41 is fixedly provided with a mounting base 42, and the connector 43 is connected to the mounting plate 41 through the mounting base 42.

[0029] As an optional solution, the connector 43 is configured as an arc-shaped plate, and the first inclined tie 4 is wrapped around the connector 43, that is, a through hole is opened on the arc-shaped plate for the steel strand to pass through, and the steel strand passes through and connects with the arc-shaped plate. Alternatively, the connector 43 is configured as a metal sleeve, with the first diagonal brace 4 sleeved inside the connector 43, and the metal sleeve is configured as an arc-shaped structure to facilitate the passage of the steel strand.

[0030] Furthermore, the connector 43 is fixedly connected to the mounting base 42 by a screw 411.

[0031] Alternatively, a bearing is installed inside the mounting base 42, and a rotating shaft is mounted on the bearing. The connecting piece 43 is fixedly connected to the rotating shaft. By setting a bearing inside the mounting base 42, when the connecting piece 43 rotates, the rotating shaft rotates synchronously on the bearing, effectively reducing the wear of the steel strand at the connecting piece 43.

[0032] In some alternative embodiments, the first diagonal brace 4 is connected to the end crossbeam 3 by a first U-bolt 46.

[0033] In some alternative embodiments, the first diagonal brace 4 is anchored to the end beam 3 via a first anchor 45.

[0034] As a preferred embodiment, a protective sleeve 44 is provided through the end crossbeam 3. The protective sleeve 44 has a flared end 441 near the diagonal bracing rod 2. The end of the first diagonal bracing member 4 passes through the protective sleeve 44 and is anchored to the end crossbeam 3 through the first anchor 45. The protective sleeve 44 and the flared end 441 can effectively reduce the wear of the steel strand at the end crossbeam 3 caused by friction.

[0035] In some alternative embodiments, the second diagonal brace 5 is configured as a steel strand or a finely rolled threaded steel bar, the top of the second diagonal brace 5 is connected to the mounting plate 41 by a second U-bolt 51, and the bottom of the second diagonal brace 5 is connected to the ground foundation by a third U-bolt 52.

[0036] Washers are also installed on the first U-bolt, the second U-bolt, and the third U-bolt. The washers have through holes and are used to install steel strands or fine-rolled threaded steel bars. When steel strands are installed on the washers, the ends of the steel strands pass through the through holes and are fixed by anchors. When fine-rolled threaded steel bars are installed on the washers, the ends of the fine-rolled threaded steel bars pass through the through holes and are locked and limited by nuts.

[0037] In addition, a drive motor 6 is fixedly installed on the top of the end column 1. The drive motor 6 is rotatably connected to the end crossbeam 3. The end crossbeam 3 is anchored to a load-bearing cable 7 by a second anchor 71.

[0038] The above are preferred embodiments of the present invention. The basic principles, main features, and advantages of the present invention have been shown and described above. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are only illustrative of the principles of the present invention. Various changes and modifications may be made to the present invention without departing from the spirit and scope thereof. All such changes and modifications fall within the scope of the present invention as claimed. The scope of protection of the present invention is defined by the appended claims and their equivalents.
