Description

Technical Field

[0001] The utility model relates to the technical field of photovoltaic power generation, in particular to a double-push rod photovoltaic bracket. Background Art

[0002] Photovoltaic mounting technology has developed rapidly in recent years due to its following characteristics: 1. The use of lightweight, high-strength materials improves durability and reduces costs; 2. Adaptable designs for diverse environments meet diverse installation requirements, such as mountainous and aquatic locations; 3. Easy maintenance and modular design facilitate rapid installation and maintenance; 4. Improved cost-effectiveness and positive global market support. These characteristics have collectively driven the widespread application and technological innovation of photovoltaic mounting systems in the photovoltaic industry, moving towards greater efficiency, intelligence, and environmental friendliness.

[0003] The existing photovoltaic bracket includes a column, a connecting sleeve, a beam, a photovoltaic panel and a telescopic push rod. The bottom of the column is fixed to the ground, the top of the column is connected to the connecting sleeve, a bearing is provided inside the connecting sleeve, the beam is rotatably connected to the connecting sleeve through the bearing, a driving arm is fixed on the beam, and one end of the telescopic push rod is connected to the driving arm, which is used to push the beam to rotate around the central axis of the bearing. An installation structure is provided on the beam for fixing the photovoltaic panel.

[0004] For the connection between the top of the column and the connecting sleeve, the top of the column and the connecting sleeve are generally fixedly connected. This way of fixing the column and the connecting sleeve cannot adjust the angle between the beam and the column. With such a design, the photovoltaic module can only be adjusted in the east-west direction, but has no adjustment ability in the north-south direction. When the earth revolves around the sun in its orbit, the earth's axis maintains an inclination of about 23.5° relative to the orbital plane. This inclination causes the direct sunlight point to move seasonally between the Tropic of Cancer and the Tropic of Capricorn. Therefore, it is necessary to ensure that the photovoltaic module has good adjustment ability in the north-south direction to ensure that sunlight directly hits the photovoltaic panel and collects as much light as possible. Utility Model Content

[0005] In order to solve the technical problem that the angle between the existing photovoltaic support beam and the column is fixed and cannot be adjusted, the utility model provides a double-push rod photovoltaic support with dynamic adjustment of the angle between the photovoltaic support beam and the column.

[0006] The technical solution adopted by the utility model to solve its technical problems is:

[0007] A double-push rod photovoltaic bracket includes a column, a connecting sleeve, a beam, a photovoltaic panel and a first telescopic push rod. The bottom of the column is fixed to the ground. The connecting sleeve includes a first connecting part and a second connecting part. The top of the column is connected to the second connecting part. A bearing is provided inside the first connecting part. The beam is rotatably connected to the first connecting part through the bearing. A driving arm is fixedly provided on the beam. The first telescopic push rod is hinged to the driving arm and is used to push the beam to rotate around the central axis of the bearing. A mounting structure is provided on the beam for fixing the photovoltaic panel. The second connecting part is rotatably connected to the top of the column. The rotation axis of the beam and the rotation axis of the second connecting part are perpendicular to each other. The first telescopic push rod is hinged to the second connecting part. A mounting part is provided below the second connecting part. It also includes a second telescopic push rod. One end of the second telescopic push rod is hinged to the second connecting part, and the other end is hinged to the mounting part.

[0008] Furthermore, the second connecting part is H-shaped, including two supporting legs at the upper end, two supporting legs at the lower end and an intermediate cross bar. The two supporting legs at the upper end of the second connecting part are fixedly connected to the first connecting part, the intermediate cross bar of the second connecting part is rotatably connected to the top of the column, and at least one of the two supporting legs at the lower end of the second connecting part is provided with a hinged support, and the first telescopic push rod and the second telescopic push rod are both hinged to the hinged support.

[0009] Furthermore, one of the legs at the lower end of the second connecting portion is provided with two hinged supports.

[0010] Furthermore, the first connecting part includes a base and a buckling piece, the base is provided with an arc-shaped groove for installing the bearing, the buckling piece and the arc-shaped groove together form a bearing fixing hole, and the buckling piece and the base are fixedly connected by bolts.

[0011] Furthermore, a mounting plate is provided at the bottom of the column, the mounting portion is fixedly provided on the mounting plate, and a support is provided at the top of the mounting portion for being hinged to the second telescopic push rod.

[0012] Furthermore, a reinforcing rib is provided between the top surface of the mounting plate and the outer wall of the column.

[0013] Furthermore, the driving arm includes a driving rod and a clamping piece. A hinge hole hinged to the first telescopic push rod is provided at one end of the driving rod, and a groove matching the crossbeam is provided at the other end. The clamping piece and the groove together form a crossbeam fixing hole. The driving rod and the clamping piece are fixedly connected by bolts to fix the driving arm on the crossbeam.

[0014] Furthermore, the crossbeam is configured as a square tube.

[0015] The beneficial effects of the utility model are:

[0016] 1. By pivoting the second connecting portion to the top of the column, with the crossbeam's axis of rotation perpendicular to the axis of rotation of the second connecting portion, this design allows for greater freedom of angle adjustment in both the east-west and north-south directions, overcoming the limitation of north-south angle adjustment in traditional designs. By introducing first and second telescopic push rods, this structure significantly enhances the overall stability and adjustment flexibility of the bracket, allowing the photovoltaic panels to be more precisely aligned with sunlight, thereby improving energy collection efficiency.

[0017] 2. The design of the second connecting part has been refined and designed into an H-shaped structure, which increases the stability of the structure. By setting an articulated support at the lower end of the support leg and hinged with the second telescopic push rod, efficient transmission of the second telescopic push rod is achieved, which improves the convenience of installation and maintenance.

[0018] 3. Two hinged supports are provided on one leg at the lower end of the second connecting part, which not only enhances the stability of the structure and helps to balance the thrust, but also avoids the torsional moment generated by providing a hinged support on each of the two legs at the lower end, which affects the stability of the device.

[0019] 4. The first connection part includes a combined design of a base and a fastener, which facilitates the installation and fixation of the bearing, ensures smooth and stable rotation of the beam, simplifies the assembly process, and improves the durability and reliability of the overall structure.

[0020] 5. A mounting plate is designed at the bottom of the column. This design strengthens the connection stability between the photovoltaic bracket and the ground, and the mounting part is designed on the mounting plate. Since the second telescopic push rod needs to overcome a large force when pushing the connecting sleeve to rotate, including the gravity of the photovoltaic panel and the photovoltaic panel mounting structure, the mounting part is designed on the mounting plate to directly transmit force to the ground, further optimizing the load-bearing capacity and adjustment performance of the overall structure.

[0021] 6. By adding reinforcing ribs between the mounting plate and the outer wall of the column, the wind pressure resistance and overall rigidity of the photovoltaic bracket are significantly improved, effectively preventing structural deformation or damage under extreme weather conditions.

[0022] 7. The structure of the driving arm has been optimized. The coordinated use of the driving rod and the clamping piece ensures the firm fixation of the beam while facilitating installation and adjustment, thus improving the ease of operation and the stability of the system.

[0023] 8. The crossbeam adopts a square tube design, which not only enhances the structural strength and rigidity of the crossbeam, but also facilitates the flat installation of photovoltaic panels, helps dissipate heat, and prolongs the service life of photovoltaic panels. At the same time, the shape of the square tube also helps to simplify the manufacturing process and reduce costs. In addition, the square tube design also facilitates the fixation of the drive arm.

It also includes a second telescopic push rod 6, one end of the second telescopic push rod 6 is hinged to the second connecting part 22, and the other end is hinged to the mounting part 7.

[0035] There is no special limitation on the shape of the connecting sleeve 2 here, as long as it can support the crossbeam 3 and realize a rotation connection around the matching hole at the top of the column 1. In order to ensure the stability of the structure, realize the efficient transmission of the second telescopic push rod 6, and improve the convenience of installation and maintenance, this scheme preferably has an H shape. It should be noted that the hinge position of the second telescopic push rod 6 and the second connecting part 22 is at a certain distance from the rotation axis of the second connecting part 22, rather than being located on the rotation axis. Only in this way can a driving torque be generated on the connecting sleeve 2 to ensure that the second connecting part 22 rotates around the rotation axis of the second connecting part 22 under the thrust of the second telescopic push rod 6.

[0036] The connection between the top of the column 1 and the second connecting portion 22 can be a fixed connection, such as welding, bolt connection, etc., or a rotational connection, such as hinged connection, or rotational connection using a bearing.

[0037] A driving arm 4 is fixedly provided on the crossbeam 3. The fixing arrangement can be that the driving arm 4 and the crossbeam 3 are connected in an integrated manner, or are welded, or are bolted, as long as the crossbeam 3 and the driving arm 4 are kept relatively fixed. There is no limitation on the structural form of the mounting structure, as long as the photovoltaic panel can be fixed to the crossbeam 3 and basic work can be performed. There is no limitation on the structure of the mounting portion 7, as long as it can support the second telescopic push rod 6. It can be set on the column 1, or on the ground, or other structures can be set on the ground to support the mounting portion 7. In general, the mounting portion 7 can be located below the second connecting portion, and its structure is not particularly limited.

[0038] In some embodiments, the second connecting portion 22 is H-shaped and includes two upper legs 222, two lower legs 222, and an intermediate crossbar 221. The two upper legs 222 of the second connecting portion 22 are fixedly connected to the first connecting portion 21, and the intermediate crossbar 221 of the second connecting portion 22 is rotatably connected to the top of the column 1.

Here, the two lower legs 222 can each be provided with an articulated support 8, or two articulated supports 8 can be provided on the same lower leg 222, as long as the rotational connection can be achieved and basic transmission is guaranteed.

[0039] In some embodiments, one of the legs 222 at the lower end of the second connecting portion 22 is provided with two hinged supports 8 .

[0040] In some embodiments, the first connecting portion 21 includes a base and a fastening member 211. The base is provided with an arcuate groove 212 for mounting a bearing. The fastening member 211 and the arcuate groove 212 together form a bearing fixing hole. The fastening member 211 and the base are fixedly connected by bolts. In addition to bolts, welding or an integrated molding structure can also be used, as long as they can fix the bearing.

[0041] In some embodiments, a mounting plate 9 is provided at the bottom of the column 1 , the mounting portion 7 is fixedly provided on the mounting plate 9 , and a support 11 is provided at the top of the mounting portion 7 for being hinged to the second telescopic push rod 6 .

[0042] In some embodiments, a reinforcing rib 10 is provided between the top surface of the mounting plate 9 and the outer wall of the column 1 .

[0043] In some embodiments, the driving arm 4 includes a driving rod 41 and a tightening member 42. A hinge hole 412 is provided at one end of the driving rod 41 for hinged connection to the first telescopic push rod 5, and a groove 411 is provided at the other end for matching with the beam 3. The tightening member 42 and the groove 411 are combined to form a beam fixing hole. The driving rod 41 and the tightening member 42 are fixedly connected by bolts for fixing the driving arm 4 on the beam 3.

[0044] In some embodiments, the crossbeam 3 is configured as a square tube. The crossbeam 3 can be a round tube or a tube with other irregular cross-sections, such as a pentagonal or hexagonal tube, as long as it can be used to install photovoltaic panels. In this solution, a square tube is preferred. This not only enhances the structural strength and rigidity of the crossbeam 3, but also facilitates the flat installation of the photovoltaic panels, helps dissipate heat, and extends the service life of the photovoltaic panels. At the same time, the square tube shape also helps to simplify the manufacturing process and reduce costs. In addition, the square tube design also facilitates the fixation of the drive arm 4.
