Description

Technical Field

[0001] This utility model relates to the field of photovoltaic equipment technology, specifically a photovoltaic support structure for high-altitude areas. Background Technology

[0002] In recent years, my country's installed capacity of renewable energy power generation has continued to grow, especially the installed capacity of photovoltaic (PV) power generation. However, with the expansion of PV power plant scale, problems with PV support systems have gradually become prominent. As a key structure supporting PV modules, the structural strength and corrosion resistance of PV support systems are crucial to ensuring the safe and stable operation of PV systems. Especially in harsh mountainous areas, PV support systems face even more severe challenges.

[0003] Referring to the Chinese patent application number 202420571873.7, entitled "A Photovoltaic Support," a scale is provided on the outer wall of the rotating disk for precise adjustment. After adjustment, the fastening cap is reversed again, so that the fastening cap abuts against the engagement plate, ensuring that the engagement plate abuts against the rotating disk, thereby achieving the purpose of adjustment. However, the above-mentioned photovoltaic support, especially in high-altitude areas with harsh climates, lacks countermeasures when encountering strong winds, and the support is prone to swaying. This directly affects the safety and stable operation of the photovoltaic power station. Especially under severe weather conditions such as strong winds and typhoons, the stability of the photovoltaic support is directly related to the safety of the power station. Therefore, we propose a photovoltaic support for high-altitude areas to solve the above problems. Utility Model Content

Two electric telescopic rods distributed front and back are hinged to the side of the hinge seat near the base. The electric telescopic rods are symmetrical about the central axis of the hinge seat, and the output rod ends of the two electric telescopic rods are hinged to the corresponding positioning pins through a spherical bearing.

[0011] Preferably, two connecting top bars distributed front to back are fixedly installed on the opposite surfaces of the left and right electric telescopic rods. A guide bracket is fixedly installed on the side of the two connecting top bars away from the connecting top bars. A vertical path groove is opened on the side of the guide bracket away from the connecting top bars.

[0012] Preferably, two protective covers are movably provided between the left and right guide brackets, symmetrically distributed front and back. Angle irons are fixedly installed at the left and right ends of the protective covers. Two sliding pins are fixedly installed on the side of the angle iron away from the protective covers. The sliding pins are slidably installed inside the vertical path groove.

[0013] Preferably, a handle is fixedly installed on the middle of the back side of both the front and rear protective covers.

[0014] Preferably, a connecting plate is fixedly installed on the upper left side and the upper right side of the protective cover, and a threaded hole is opened through the top of each connecting plate, wherein a wing bolt is screwed into the internal thread of two of the threaded holes.

[0015] Preferably, limiting rocker arms are fixedly installed at the middle of the left and right sides of the aluminum profile tray. The limiting rocker arms extend to the bottom periphery of the aluminum profile tray. An internal threaded tube is fixedly installed on the lower part of the opposite side of the two limiting rocker arms. A positioning plate is fixedly installed on the middle of the opposite side of the two side frame plates. An arc-shaped groove is opened through the opposite surface of the two positioning plates.

[0017] Preferably, two square tubes distributed front to back are fixedly installed between the left and right bases.

[0018] This utility model has the following beneficial effects:

[0019] 1. This utility model utilizes the extension of the output rod of an electric telescopic rod to push the push block to move, causing both the lower and upper rocker arms to rotate along the hinge point with the push block. This causes the side frame plate to move downwards, and through the pivot pin, it drives the aluminum profile tray and the photovoltaic panel located on top of it to move downwards together until the output rod of the electric telescopic rod is fully extended and the aluminum profile tray reaches its lowest position. This lowers the height of the photovoltaic panel by the height between the photovoltaic panels, thus lowering the center of gravity. This helps to reduce the swaying of the support structure during strong winds, preventing the support structure from collapsing due to excessive swaying.

[0020] 2. In this utility model, by manually pushing the handle, the protective cover, angle iron and sliding pin continue to move, so that the sliding pin continues to slide along the inner wall of the vertical path groove. From the corner position of the vertical path groove, the two sliding pins change from a horizontal state to a vertical state. Therefore, the two protective covers flip in the middle and cover the top of the aluminum profile tray, that is, to cover and protect the photovoltaic panel on the top of the aluminum profile tray, so as to prevent nearby tree branches and other objects from being blown to the top of the photovoltaic panel in strong winds, and to prevent the photovoltaic panel from being damaged by tree branches.

Detailed Implementation

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Please see Figures 1-7 A photovoltaic support system for high-altitude areas includes a base 10, a lower rocker arm 20, and a pusher block 30. There are two bases 10, symmetrically distributed left and right. The lower rocker arms 20 are hinged to the front and rear of the two bases 10 respectively. The pusher block 30 is hinged to the top of the lower rocker arm 20. An upper rocker arm 40 is hinged to the top of the pusher block 30, and a side frame plate 50 is hinged to the top of the upper rocker arm 40. There are two side frame plates 50, and an aluminum profile tray 70 is rotatably mounted between the two side frame plates 50. A pivot pin 60 is fixedly installed at the center of the opposite face of each side frame plate 50. The aluminum profile tray 70 is rotatably mounted around the two pivot pins 60. The length of the lower rocker arm 20 is equal to the length of the upper rocker arm 40. The system is ready for use after the two bases 10 are installed on the ground in the installation area and positioned using ground bolts, and then the photovoltaic panels are installed on top of the aluminum profile tray 70 and the wiring is connected.

[0031] In this embodiment, a positioning pin 80 is fixedly installed on the middle of the outer side of the push block 30, and a hinge seat 90 is fixedly installed on the middle of the back of the two bases 10. Two electric telescopic rods 100 distributed front and back are hinged to the side of the hinge seat 90 near the base 10. The electric telescopic rods 100 are symmetrical about the central axis of the hinge seat 90, and the output rod ends of the two electric telescopic rods 100 are hinged to the corresponding positioning pins 80 through a joint bearing. When encountering strong winds, the workers first loosen the fastening bolts inside the screw hole 1017, so that the two protective covers 104 can be slid to the sides along the inside of the vertical path groove 103 until they are located on the vertical path. After the bend in the groove 103, each electric telescopic rod 100 is activated. The output rods of each electric telescopic rod 100 extend, pushing the push block 30 to move. This causes the lower rocker arm 20 and the upper rocker arm 40 to rotate along the hinge with the push block 30, causing the side frame plate 50 to move downward. Through the pivot pin 60, the aluminum profile tray 70 and the photovoltaic panel on top of it move downward together until the output rods of the electric telescopic rod 100 are fully extended and the aluminum profile tray 70 reaches its lowest position. This lowers the height of the photovoltaic panel between the photovoltaic panels, thus lowering the center of gravity. This helps to reduce the swaying of the support structure during strong winds, preventing excessive swaying and potential collapse.

[0032] In this embodiment, two connecting top bars 101, distributed front to back, are fixedly installed on the opposite surfaces of the two electric telescopic rods 100. A guide bracket 102 is fixedly installed on the side of the two connecting top bars 101 away from the connecting top bars 101. A vertical path groove 103 is formed on the side of the guide bracket 102 away from the connecting top bars 101. Two protective covers 104, symmetrically distributed front to back, are movably installed between the two guide brackets 102. Angle irons 105 are fixedly installed on the left and right ends of the protective covers 104. Two sliding pins 106 are fixedly installed on the side of the angle irons 105 away from the protective covers 104. The sliding pins 106 are slidably installed inside the vertical path groove 103. A handle 107 is fixedly installed on the middle of the opposite sides of the two protective covers 104. A connecting plate 108 is fixedly installed on the upper left and upper right sides of the protective covers 104. A screw thread is formed through the top of each connecting plate 108. The perforated holes 109, two of which are threaded holes 109, have wing bolts 1010 screwed into their internal threads. Two threaded holes 1017, distributed front to back, are opened on the center of the back of the left and right guide brackets 102. Both threaded holes 1017 penetrate the interior of the guide bracket 102 and extend into the vertical path groove 103. Tensioning bolts are threaded into the interior of each threaded hole 1017, and the ends of the tensioning bolts abut against the sides of the angle iron 105. When the aluminum profile tray 70 descends to its lowest height, the operator manually pushes the handle 107, causing the protective cover 104, angle iron 105, and sliding pins 106 to continue moving. This allows the sliding pins 106 to continue sliding along the inner wall of the vertical path groove 103. From the bend in the vertical path groove 103, the two sliding pins 106 change from a horizontal to a vertical position. Therefore, the two protective covers 104 flip inwards, covering the top of the aluminum profile tray 70 (as per the instruction manual). Figure 7 As shown in the diagram, the photovoltaic panel on top of the aluminum profile tray 70 is covered to prevent nearby tree branches from being blown onto the top of the photovoltaic panel during strong winds, thus preventing the photovoltaic panel from being damaged by the branches. After the two protective covers 104 are placed on top of the photovoltaic panel, the staff randomly screws the wing bolts 1010 so that the threads of the wing bolts 1010 are screwed into the front and rear threaded holes 109, thereby connecting the front and rear connecting plates 108 to prevent the front and rear protective covers 104 from moving, thereby improving the protection effect on the photovoltaic panel.

[0033] In this embodiment, limiting rocker arms 1012 are fixedly installed on the middle of the left and right sides of the aluminum profile tray 70. The limiting rocker arms 1012 extend to the bottom periphery of the aluminum profile tray 70. An internal threaded tube 1013 is fixedly installed on the lower back of both limiting rocker arms 1012. Positioning plates 1014 are fixedly installed on the middle back of both left and right side frame plates 50. An arc-shaped groove 1015 is formed through the opposing surfaces of both positioning plates 1014. The center of the arc-shaped groove 1015 is concentric with the shaft pin 60, and the position of the arc-shaped groove 1015 corresponds to the position of the internal threaded tube 1013. A positioning bolt 1016 is inserted into the arc-shaped groove 1015, and the positioning bolt 1016 is threaded onto the internal threaded tube 1013. Inside 013, during normal use, if it is necessary to adjust the angle of the photovoltaic panel, the two positioning bolts 1016 on the left and right are loosened. Then, under the rotational connection between the two pivot pins 60 and the aluminum profile tray 70, the aluminum profile tray 70 can be rotated to adjust its angle, thereby obtaining the appropriate power generation efficiency. After the angle of the aluminum profile tray 70 is adjusted, the two positioning bolts 1016 on the left and right need to be tightened so that the positioning bolts 1016 are pressed against the side of the positioning plate 1014, which can limit the angle of the aluminum profile tray 70 to prevent the adjusted angle from changing again, and also ensure the stability of the aluminum profile tray 70.

[0034] In this embodiment, two square tubes 1011 distributed front and back are fixedly installed between the left and right bases 10. By fixing two wing bolts 1010 between the left and right bases 10, the connection between the left and right bases 10 can be strengthened, thereby improving the overall stability of the bracket.

[0035] The working principle involves installing the two bases 10 on the ground in the installation area and positioning them with ground bolts. Then, the photovoltaic panel is installed on top of the aluminum profile tray 70, and the wiring is connected for use. In windy weather, the operator first loosens the fastening bolts inside the screw holes 1017. This allows the two protective covers 104 to slide to the sides along the vertical path groove 103 until they reach the angled position. Then, each electric telescopic pole 100 is activated. The output rod extends, pushing the push block 30 to move, causing the lower rocker arm 20 and the upper rocker arm 40 to rotate along the hinge with the push block 30, causing the side frame plate 50 to move downward, and through the shaft pin 60, driving the aluminum profile tray 70 and the photovoltaic panel on top of it to move downward together until the output rod of the electric telescopic rod 100 is fully extended, and the aluminum profile tray 70 just reaches the lowest position, thereby lowering the photovoltaic panel by the height between the photovoltaic panels, that is, lowering the center of gravity, to resist the swaying of the support during strong winds, so as to prevent the support from collapsing and being damaged due to excessive swaying;

[0036] After the aluminum profile pallet 70 descends to its lowest height, the operator manually pushes the handle 107, causing the protective cover 104, angle iron 105, and sliding pin 106 to continue moving. This allows the sliding pin 106 to continue sliding along the inner wall of the vertical path groove 103. From the corner of the vertical path groove 103, the two sliding pins 106 change from a horizontal to a vertical position. As a result, the two protective covers 104 flip inward, covering the top of the aluminum profile pallet 70 (as per the instruction manual). Figure 7 As shown in the figure, the photovoltaic panel on top of the aluminum profile tray 70 is covered and protected to prevent nearby tree branches from being blown to the top of the photovoltaic panel during strong winds, so as to prevent the photovoltaic panel from being damaged by the tree branches. After the two protective covers 104 are covered on the top of the photovoltaic panel, the staff randomly screws the wing bolts 1010 so that the threads of the wing bolts 1010 are screwed into the front and rear threaded holes 109, thereby connecting the front and rear connecting plates 108 to prevent the front and rear protective covers 104 from moving, thereby improving the protection effect of the photovoltaic panel.

[0037] It should be noted that during normal use of this bracket, if it is necessary to adjust the angle of the photovoltaic panel facing the light, the two positioning bolts 1016 on the left and right sides are loosened. Then, under the rotational connection between the two pivot pins 60 on the left and right sides and the aluminum profile tray 70, the aluminum profile tray 70 can be rotated to adjust its angle, thereby obtaining the appropriate power generation efficiency. After the angle of the aluminum profile tray 70 is adjusted, the two positioning bolts 1016 on the left and right sides need to be tightened so that the positioning bolts 1016 are pressed against the side of the positioning plate 1014, which can limit the angle of the aluminum profile tray 70 to prevent the adjusted angle from changing again, and also ensure the stability of the aluminum profile tray 70.

[0038] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
