Description

Technical Field

[0001] This utility model belongs to the field of photovoltaic support technology, and specifically relates to a photovoltaic support with angle adjustment function. Background Technology

[0002] Photovoltaic brackets are the core support structures in solar photovoltaic power generation systems used to support, fix, and adjust photovoltaic modules. Their main function is to ensure that the photovoltaic modules receive sunlight at the optimal angle, thereby improving power generation efficiency.

[0003] Currently, Chinese utility model patent CN210780647U discloses an adjustable-angle photovoltaic panel bracket with a cleaning function, belonging to the field of photovoltaic equipment technology. It includes a device base, a central rotating shaft, a movable gear, a servo motor, a movable bracket, a second servo motor, a meshing gear, a first speed-measuring fan, a second speed-measuring fan, a movable bearing, a bearing inner ring, a movable photovoltaic panel, a top functional plate, an internal sliding rod, a sliding structure, a second movable bracket, an electric motor, a cable chain, and a cable chain. The central rotating shaft is fixedly connected to the center of the device base, and the movable gear is movably connected to the top of the central rotating shaft via a bearing. A servo motor is fixedly connected to the right side of the device base. The second speed-measuring fan is horizontally positioned. The first and second speed-measuring fans can detect wind speeds in different directions and then feed the wind speed feedback to a control switch. The control switch then controls the servo motor to drive the movable gear, causing the movable gear to rotate and change the angle of the movable bracket, thereby changing the windward angle of the movable bracket.

[0004] In the above-disclosed structure, the rotation of the photovoltaic panel is directly controlled by the meshing of the meshing gear and the inner ring of the bearing. This also causes the motor, meshing gear and the inner ring of the bearing to directly bear the weight of the photovoltaic panel, which makes the above components prone to bending or deformation during long-term use.

[0005] Furthermore, the motor needs to be constantly connected, and the self-locking mechanism of the motor is used to maintain the angle, resulting in high operating costs. At the same time, the photovoltaic panel cannot maintain its position when the motor is under maintenance, and the motor will be under constant stress and creep damage when it is under heavy load for a long time. Utility Model Content

[0006] The purpose of this invention is to address the shortcomings of existing technologies by proposing a photovoltaic bracket with angle adjustment function.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: a photovoltaic bracket with angle adjustment function, comprising a solar panel, a triangular bracket fixed at the bottom of the solar panel, a base bracket provided below the triangular bracket, a shaft rotatably connected to the inner wall of the base bracket, and a semi-circular part fixed to the circumference of the shaft; the semi-circular part fixed at the bottom of the triangular bracket, and an engagement groove formed on the circumference of the semi-circular part; a threaded rod rotatably connected to the top of the base bracket through a bearing seat, the surface of the threaded rod engaging with the engagement groove.

[0008] Preferably, the top of the base support is provided with a recessed arc groove, and the inner wall of the recessed arc groove is slidably connected to the circumference of the semi-circular part; the inner wall of the recessed arc groove is provided with multiple trapezoidal arc grooves, and a trapezoidal arc part is slidably connected to the inner wall of the trapezoidal arc groove, and the top of the trapezoidal arc part is fixed to the circumference of the semi-circular part.

[0009] Preferably, the triangular bracket has bracket grooves on both sides of its bottom.

[0010] Preferably, both ends of the frame groove are provided with arc-shaped ends, and the surface of the arc-shaped ends is covered with a rubber layer.

[0011] Preferably, the semi-circular part has multiple annular grooves on its circumference, and the annular grooves are located between the meshing inclined groove and the trapezoidal arc part.

[0012] Preferably, ratchet wheels are fixed to both ends of the shaft, the ratchet wheels are located on the inner wall of the base bracket, a limiting member is rotatably connected to the inner wall of the base bracket, a return spring is fixed to one side of the limiting member, and one end of the return spring is fixed to the inner wall of the base bracket.

[0013] Preferably, the inner wall of the base support is rotatably connected to a rotating component via a rotating shaft, and a control column is fixed at one end of the base support.

[0014] Preferably, one end of the control column is a rounded rectangle, and a swivel groove is provided on one side of the base bracket. The edge of the swivel groove is rounded, and a reflective strip is glued to the rounded edge.

[0015] In summary, this utility model has the following beneficial effects:

[0016] 1. This utility model sets a threaded rod and a semi-circular part to engage with a groove near the solar panel, thereby adjusting the angle of the solar panel at a position with a small lever arm. At the same time, the engagement between the threaded rod and the groove has self-locking properties, so that after the angle of the solar panel is adjusted, the external motor driving the threaded rod will not be under stress, thereby increasing its service life. Moreover, the external motor does not need to be constantly connected to the threaded rod, which greatly increases its service life and reduces manufacturing costs.

[0017] 2. This utility model uses a recessed arc groove to support the semi-circular part. Even if the threaded rod slips and fails, the triangular bracket will not rotate too much. When controlling the rotation of the triangular bracket, the contact between the arc groove of the triangular bracket and the top of the base bracket can limit the rotation angle of the triangular bracket. When in contact, the arc end and its rubber layer provide cushioning while increasing the contact area. At the same time, the cooperation between the trapezoidal arc groove and the trapezoidal arc part limits the rotation of the triangular bracket to keep it on the same plane, preventing it from shifting due to friction during rotation and causing abnormal wear, thus improving the service life of the equipment.

[0018] 3. This utility model restricts the rotation of the shaft by cooperating with a ratchet and multiple limiting components. When the shaft attempts to reverse, the ratchet prevents accidents caused by reversal. At the same time, it shares the force borne by the threaded rod when it is self-locking, thereby improving the service life of the threaded rod. Attached Figure Description

[0035] To make the technical means, creative features, and achieved objectives and effects of this utility model easier to understand, the present utility model is further described below with reference to specific embodiments and accompanying drawings. However, the following embodiments are merely preferred embodiments of this utility model and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments described in the implementation plan without creative effort are all within the protection scope of this utility model.

[0036] The specific embodiments of this utility model are described below with reference to the accompanying drawings:

[0037] Example 1:

[0038] refer to Figures 1-6 A photovoltaic bracket with angle adjustment function includes a solar panel 1, a triangular bracket 2 fixed at the bottom of the solar panel 1, a base bracket 201 below the triangular bracket 2, a shaft 205 rotatably connected to the inner wall of the base bracket 201, and a semi-circular part 202 fixed on the circumference of the shaft 205; the semi-circular part 202 is fixed at the bottom of the triangular bracket 2, and a meshing groove 203 is opened on the circumference of the semi-circular part 202; a threaded rod 204 is rotatably connected to the top of the base bracket 201 through a bearing seat, and the surface of the threaded rod 204 meshes with the meshing groove 203.

[0039] Specifically, by setting a threaded rod 204 near the solar panel 1 and engaging with the meshing groove 203 of the semi-circular part 202, the angle of the solar panel 1 can be adjusted at a position with a small lever arm. At the same time, the engagement between the threaded rod 204 and the meshing groove 203 has a self-locking property, so that after the angle of the solar panel 1 is adjusted, the external motor driving the threaded rod 204 will not be under stress, thereby increasing its service life. Moreover, the external motor does not need to be constantly connected to the threaded rod 204, which greatly increases its service life and reduces manufacturing costs.

[0040] The base bracket 201 has a recessed arc groove 4 at the top, and the inner wall of the recessed arc groove 4 is slidably connected to the circumference of the semi-circular part 202; the inner wall of the recessed arc groove 4 has multiple trapezoidal arc grooves 901, and the inner wall of the trapezoidal arc groove 901 is slidably connected to a trapezoidal arc part 9, and the top of the trapezoidal arc part 9 is fixed to the circumference of the semi-circular part 202; the bottom of the triangular bracket 2 has a frame arc groove 401 on both sides; the frame arc groove 401 has an arc end 5 at both ends, and the surface of the arc end 5 is covered with a rubber layer.

[0041] Specifically, by using the recessed groove 4 to support the semi-circular part 202, even if the threaded rod 204 slips and fails, the triangular bracket 2 will not rotate too much. Furthermore, when controlling the rotation of the triangular bracket 2, the contact between the recessed groove 401 of the triangular bracket 2 and the top of the base bracket 201 can limit the rotation angle of the triangular bracket 2. During contact, the arc end 5 and its rubber layer provide cushioning while increasing the contact area. At the same time, the cooperation between the trapezoidal groove 901 and the trapezoidal part 9 restricts the rotation of the triangular bracket 2 to keep it on the same plane, preventing it from shifting due to friction during rotation and causing abnormal wear, thus improving the service life of the equipment.

[0042] The semi-circular part 202 has multiple annular grooves 6 on its circumference, and the annular grooves 6 are located between the meshing inclined groove 203 and the trapezoidal part 9.

[0043] Specifically, by reducing the contact area between the circumferential surface of the semicircular part 202 and the recessed groove 4 through the annular groove 6, friction is reduced, wear is reduced, and the service life of the semicircular part 202 is improved. In addition, the lower friction makes it easier for the triangular bracket 2 to rotate, which can significantly reduce the jerking sensation when turning and improve the smoothness of operation.

[0044] Both ends of the shaft 205 are fixed with ratchet 3. The ratchet 3 is located on the inner wall of the base bracket 201. The inner wall of the base bracket 201 is rotatably connected with a limiting member 301. A return spring 701 is fixed on one side of the limiting member 301. One end of the return spring 701 is fixed to the inner wall of the base bracket 201.

[0045] Specifically, the ratchet 3, in cooperation with multiple limiting components 301, restricts the rotation of the shaft 205. When it attempts to reverse, the ratchet prevents accidents caused by reversal. At the same time, it shares the force borne by the threaded rod 204 when it is self-locking, thereby improving the service life of the threaded rod 204.

[0046] The inner wall of the base bracket 201 is rotatably connected to a rotating component 7 via a rotating shaft, and a control column 8 is fixed at one end of the rotating component 7.

[0047] Specifically, by controlling the fixing of the column 8 and the rotating part 7, the operator can easily control the limiting part 301 of the rotating part 7, so that the ratchet 3 can be released from the limitation of the limiting part 301, thereby reversing and adjusting the angle of the solar panel 1.

[0048] One end of the control column 8 is a rounded rectangle, and a swivel groove 801 is provided on one side of the base bracket 201. The edge of the swivel groove 801 is rounded, and a reflective strip is glued to the rounded edge.

[0049] Specifically, the swivel groove 801 allows workers to control the limiting member 301 located on the inner wall of the base bracket 201 without disassembling the base bracket 201, thereby facilitating the adjustment of the angle of the solar panel 1. Furthermore, the rounded edge of the swivel groove 801 prevents scratches to workers and improves the user experience.

[0050] Example 2:

[0051] refer to Figures 1-6 Based on the structure disclosed in this utility model, staff used it in a plateau wind farm in Qinghai. The photovoltaic support structure (solar panel 1, power 550W, size 1756×1096mm) was deployed in October 2023. The local average annual wind speed is 8.5m / s, and the winter snow load reaches 1.5kN / m. 2 During installation, the base bracket 201 is made of Q355B steel and anchored to the concrete foundation. The triangular bracket 2 and the semi-circular part 202 are hot-dip galvanized for corrosion protection.

[0052] During the commissioning phase, an external servo motor drives the M24 threaded rod 204 to rotate, causing the meshing groove 203 to push the semi-circular part 202 to slide within the recessed arc groove 4 (reducing the friction coefficient to 0.08), thereby raising the solar panel 1 from 15° to the optimal tilt angle of 42°. During this process, the trapezoidal arc part 9 slides along the trapezoidal arc groove 901 (with a tolerance of ±0.05mm), effectively resisting the offset caused by lateral wind loads; the design of the annular groove 6 reduces the contact area by 37%, and the steering torque is reduced to 18 N·m.

[0053] During the strong wind test (wind speed 22m / s), the arc end 5 of the frame groove 401 (covered with neoprene rubber) contacts the top surface of the base support 201 to buffer and disperse vibration energy; at the same time, the ratchet 3 (module 2.5) engages with the limiting part 301 under the action of the return spring 701 (elastic coefficient 12N / mm), successfully suppressing the reverse displacement of the shaft 205 (monitoring shows angle fluctuation ≤0.3°). After the blizzard, the self-locking structure of the threaded rod 204 can bear 1.2 tons without slipping. The operator releases the ratchet 3 lock by moving the control column 8 through the rotating groove 801 (with EN471 standard reflective strip on the edge), and rotates the threaded rod 204 in the reverse direction to lower the plate surface to 28° to accelerate the snow sliding off.

[0054] After one year of operation, the bracket maintains an angular stability of ±0.5° in an environment ranging from -30℃ to 65℃, requiring no lubrication or maintenance; compared with traditional gear-adjustable brackets, the motor failure rate has decreased by 92%.

[0055] The working principle of this utility model is as follows: when the staff needs to adjust the tilt angle of the solar panel 1, the external motor drives the threaded rod 204 to rotate.

[0056] Because the surface of the threaded rod 204 meshes with the meshing groove 203 on the circumference of the semi-circular part 202 fixed to the bottom of the triangular bracket 2, the rotation of the threaded rod 204 will push the meshing groove 203, forcing the semi-circular part 202 to slide along the inner wall of the recessed arc groove 4 at the top of the base bracket 201. At the same time, the trapezoidal arc part 9 on the circumference of the semi-circular part 202 moves synchronously in the trapezoidal arc groove 901 on the inner wall of the recessed arc groove 4, ensuring that the semi-circular part 202 maintains planar motion without deviation; the displacement of the semi-circular part 202 causes the triangular bracket 2 fixed to it to rotate around the axis of the shaft 205, thereby changing the tilt angle of the solar panel 1.

[0057] During rotation, the arc groove 401 at the bottom of the triangular bracket 2 gradually comes into contact with the top of the base bracket 201. The rubber layer on its arc end 5 increases the contact area and provides cushioning, limiting the maximum rotation angle. The annular groove 6 on the circumference of the semi-circular part 202 reduces the contact area with the countersunk groove 4, reducing friction loss and making the rotation smoother. After adjustment, the self-locking characteristics of the meshing inclined groove 203 and the threaded rod 204 fix the angle, and the external motor can be disengaged.

[0058] Meanwhile, the ratchet 3 at both ends of the shaft 205 engages with the limiting member 301 on the inner wall of the base bracket 201 under the action of the return spring 701, forming a reverse lock to prevent the solar panel 1 from falling back accidentally and to share the load of the threaded rod 204. If reverse adjustment is required, the corresponding control column 8 is moved by the rotating groove 801 on the side wall of the base bracket 201, which drives the rotating member 7 to lift the corresponding limiting member 301 and disengage from the ratchet 3. After the lock is released, the reverse drive of the threaded rod 204 can realize the angle adjustment.

[0059] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model.
