Description

Technical Field

[0001] This utility model relates to the field of photovoltaic brackets, specifically a wind-resistant photovoltaic bracket. Background Technology

[0002] Wind-resistant photovoltaic (PV) mounting systems are structures designed to effectively withstand wind impacts, protect PV modules, and improve system stability in strong wind environments. However, existing wind-resistant PV mounting systems typically suffer from large space requirements and complex structures, leading to an increased overall size, particularly in thickness, compared to ordinary PV mounting systems. This increases the wind-exposed area, affecting wind resistance and making transportation and handling difficult. For example, Chinese utility model patent CN119298803A discloses a windproof PV module structure, including a fixed base, a windproof cover mounted on top of the fixed base, a flipping structure located inside the windproof cover, and locking structures located on both sides inside the windproof cover. This invention uses a hydraulic pusher to move the mounting plate, causing the mounting frame to move upwards away from the inside of the windproof cover and flip around a pivot rod, adjusting the angle of the PV panel. Activating the hydraulic pusher retracts the PV panel, retracting it into the windproof cover. The complex structure and large overall size of the windproof PV module can easily affect the wind resistance of the entire PV mounting system and make transportation and handling difficult. Summary of the Invention

[0003] The purpose of this utility model is to provide a wind-resistant photovoltaic support system, which aims to overcome the aforementioned problems existing in the prior art.

[0004] To achieve this objective, the present invention provides the following technical solution:

[0005] A wind-resistant linkage photovoltaic support includes photovoltaic panels, longitudinal beams and cross beams, and a wind-resistant linkage mechanism. Several longitudinal beams are fixedly laid on the upper surface of several cross beams. Several photovoltaic panels are rotatably arranged between two of the aforementioned longitudinal beams through the wind-resistant linkage mechanism. By flipping forward and backward, the photovoltaic panels can switch back and forth between being close to the longitudinal beams and being inclinedly arranged on the longitudinal beams.

[0006] The aforementioned wind-resistant linkage mechanism includes a support arm, a nut seat, a screw, a motor, and a second bearing seat;

[0007] One end of the outer frame of the photovoltaic panel is rotatably connected to the upper end face of the longitudinal beam, the middle of the outer frame is rotatably connected to one end of the support arm, and the other end of the support arm passes through the longitudinal beam and is rotatably connected to the nut seat.

[0008] The nut seat is threaded onto the outside of the aforementioned screw, and the nut seat can slide against the lower end face of the longitudinal beam; the screw is rotatably mounted on the lower end face of the longitudinal beam through several second bearing seats, and the screw extends along the length of the longitudinal beam, with the aforementioned motor mounted on one end of the screw to rotate it.

[0009] Furthermore, the aforementioned nut seat is provided with a connecting plate, on the upper end face of which a number of steel balls are rotatably mounted, and the steel balls can slide against the lower end face of the longitudinal beam.

[0010] Furthermore, it also includes a mounting cover with a hollowed-out portion. The connecting plate is provided with a mounting groove, and the mounting cover is fixedly connected to the upper end face of the connecting plate. The steel ball can be rolled and encapsulated inside the spherical cavity formed by the mounting cover and the mounting groove, and the upper end of the steel ball protrudes from the hollowed-out portion of the mounting cover to slide against the lower end face of the longitudinal beam.

[0011] Furthermore, the upper end face of the connecting plate is provided with a connecting part for rotating the connecting support arm; several steel balls are arranged on both sides of the connecting part of the connecting plate.

[0012] Furthermore, the aforementioned wind-resistant linkage mechanism includes a first bearing seat, and a first connecting shaft is provided on both sides of one end of the outer frame. The first connecting shaft is rotatably mounted on the first bearing seat, and the first bearing seat is fixed to the upper end face of the longitudinal beam.

[0013] Furthermore, the aforementioned motor is fixed to the crossbeam via a mounting plate.

[0014] Furthermore, the upper and lower end faces of the aforementioned longitudinal beams are provided with clearance openings for the support arms to pass through.

[0015] Furthermore, two photovoltaic panels are arranged along the length of the longitudinal beam, and the wind-resistant linkage mechanism of the two photovoltaic panels shares a single screw.

[0016] Compared with the prior art, this utility model has the following advantages:

[0017] Firstly, the wind-resistant linkage mechanism of this utility model includes a support arm, a nut seat, a screw, a motor, and a second bearing seat. The support arm is movably inserted through the longitudinal beam, with its upper end rotatably connected to the outer frame of the photovoltaic panel and its lower end rotatably connected to the nut seat. Simultaneously, the screw, which cooperates with the nut seat, is rotatably fixed to the lower end face of the longitudinal beam. The rotation of the screw causes the nut seat to slide along the longitudinal beam, thereby causing the photovoltaic panel to rotate via the support arm. In strong winds, this allows the photovoltaic panel to be retracted and pressed tightly against the longitudinal beam, preventing the upper and lower ends of the photovoltaic panel from being subjected to wind force and improving wind resistance. Furthermore, because the support arm passes through the longitudinal beam, and the screw and nut seat are assembled to the lower end face of the longitudinal beam and located between the crossbeam and the longitudinal beam, the overall thickness of the photovoltaic support structure is not increased. Compared to ordinary fixed photovoltaic supports, the change in the wind-receiving area of ​​the entire photovoltaic support structure is minimal.

[0018] Secondly, the wind-resistant linkage mechanism of this utility model can also adjust the tilt angle of the photovoltaic panel according to the changes in sunlight, so that the tilt angle of the photovoltaic panel matches the solar altitude angle as much as possible, so as to obtain the maximum solar radiation energy and thus generate the maximum power generation.

[0025] The specific embodiments of this utility model are described below with reference to the accompanying drawings. Many details are described below to provide a comprehensive understanding of this utility model; however, those skilled in the art can implement this utility model without these details.

[0026] like Figures 1 to 6 As shown, a wind-resistant photovoltaic support system includes photovoltaic panels 1, longitudinal beams 2, crossbeams 3, and a wind-resistant linkage mechanism 4. Several longitudinal beams 2 are fixedly laid on the upper surfaces of several crossbeams 3 via connectors 203. Several photovoltaic panels 1 are rotatably mounted between two longitudinal beams 2 via the wind-resistant linkage mechanism 4. By rotating the photovoltaic panels forward and backward, they can switch between being flush against the longitudinal beams 2 and being tilted relative to the longitudinal beams 2.

[0027] like Figures 1 to 6 As shown, the wind-resistant linkage mechanism 4 includes a first bearing seat 41, a support arm 42, a nut seat 43, a screw 44, a motor 45, and a second bearing seat 46.

[0028] like Figures 1 to 6 As shown, one end of the outer frame 11 of the photovoltaic panel 1 is rotatably connected to the upper end face of the longitudinal beam 2.

[0029] Specifically, the outer frame 11 has a first connecting shaft 111 on both sides of one end. The first connecting shaft 111 is rotatably mounted on the first bearing seat 41, and the first bearing seat 41 is fixed to the upper end face of the longitudinal beam 2.

[0030] Specifically, the upper and lower end faces of the longitudinal beam 2 are provided with clearance openings 21 for the support arm 42 to pass through, and the crossbeam 3 is provided with clearance grooves 31 for the screw 44 to avoid it.

[0031] like Figures 1 to 6 As shown, the outer frame 11 of the photovoltaic panel 1 is rotatably connected to one end of the support arm 42, and the other end of the support arm 42 passes through the longitudinal beam 2 and is rotatably connected to the nut seat 43.

[0032] Specifically, the outer frame 11 of the photovoltaic panel 1 has a second connecting shaft 112 on both sides of the middle part, and the second connecting shaft 112 is rotatably disposed at one end of the support arm 42.

[0033] Specifically, the nut seat 43 is provided with a connecting plate 432, and the upper end surface of the connecting plate 432 is provided with a connecting part 431. The other end of the support arm 42 passes through the longitudinal beam 2 and is rotatably connected to the connecting part 431. There are two connecting parts 431, which are used to rotatably connect two support arms 42 respectively, and the two support arms 42 are respectively assembled on two horizontally adjacent photovoltaic panels 1.

[0034] Of course, the two ends of the support arm 42 can also be rotatably connected to the nut seat 43 and the middle of the outer frame 11 of the photovoltaic panel 1 via damping pivots (not shown in the figure) to provide damping effect.

[0035] like Figures 1 to 6 As shown, the nut seat 43 is threaded onto the outside of the screw 44, and the nut seat 43 can slide against the lower end face of the longitudinal beam 2. The screw 44 is rotatably mounted on the lower end face of the longitudinal beam 2 via several second bearing seats 46, and the screw 44 extends along the length of the longitudinal beam 2. One end of the screw 44 is equipped with a motor 45 to rotate it. Specifically, the screw 44 has a threaded section 441, the nut seat 43 is threaded onto the threaded section 441, and limiting members 442 are provided at both ends of the threaded section 441 to prevent the nut seat 43 from slipping off the threaded section 441. For better load-bearing capacity, the screw 44 is equipped with second bearing seats 46 at both ends near the threaded section 441. For easy installation and removal, the motor 45 is fixed to the crossbeam 3 via a mounting plate 47, and the output shaft of the motor 45 is fixedly connected to one end of the screw 44 via a coupling (not shown in the figure). This is conventional technology in the art and will not be described in detail here.

[0036] Since the nut seat 43 can slide against the lower end face of the longitudinal beam 2, when the screw 44 rotates, the nut seat 43 can move along the screw 44, thereby driving the photovoltaic panel 1 to flip up and down through the support arm 42.

[0037] Due to the weight of the photovoltaic panel 1 and the support arm 42, the screw 44 will not easily rotate when the motor 45 is not outputting rotational power. Preferably, the motor 45 is a self-locking motor, which can further stabilize the screw 44.

[0038] In the attached diagram, each screw 44 is equipped with a motor as motor 45. These motors need to rotate synchronously to ensure that the photovoltaic panel 1 can be rotated normally. Synchronization of multiple motors is a conventional technical means in this field and will not be described in detail here.

[0039] In addition, multiple screws 44 can also be connected to the same horizontally extending linkage shaft, and the linkage shaft can be driven to rotate by a motor, thereby driving multiple screws 44 to rotate synchronously. Moreover, the linkage shaft and each screw 44 can be connected by a worm gear structure, so that the transmission from the linkage shaft to the screw 44 has a self-locking capability. These are also conventional technical means in this field, and will not be described in detail here.

[0040] like Figures 1 to 6 As shown, preferably, two photovoltaic panels 1 are arranged along the length of the longitudinal beam 2, and the wind-resistant linkage mechanism 4 of the two photovoltaic panels 1 shares a single screw 44. In this case, the screw 44 has two threaded sections 441, and each threaded section 441 is equipped with a nut seat 43 for driving the two photovoltaic panels 1 respectively.

[0041] like Figures 1 to 6 As shown, the nut seat 43 has several steel balls 4301 rolled on the upper end face of its connecting plate 432, and the steel balls 4301 can slide against the lower end face of the longitudinal beam 2 to reduce the friction between the nut seat 43 and the support arm 42 when the nut seat 43 moves along the screw 44.

[0042] Specifically, it also includes a mounting cover 4302 with a hollowed-out portion, and a mounting groove 4320 provided on the connecting plate 432. When the mounting cover 4302 is fixedly connected to the upper end face of the connecting plate 432, the steel ball 4301 can be rolled and encapsulated inside the spherical cavity formed by the mounting cover 4302 and the mounting groove 4320, and the upper end of the steel ball 4301 protrudes from the hollowed-out portion of the mounting cover 4302 to slide against the lower end face of the longitudinal beam 2.

[0043] like Figures 1 to 6 As shown, preferably, the connecting plate 432 has a plurality of steel balls 4301 arranged on both sides of the connecting portion 431. The number of steel balls 4301 in each row is not limited to three.

[0044] The above are merely specific embodiments of this utility model, but the design concept of this utility model is not limited thereto. Any non-substantial modifications made to this utility model using this concept shall be considered as an infringement of the protection scope of this utility model.
