Description

Technical Field

[0001] The present invention relates to the technical field of supporting structures of photovoltaic modules, and in particular to a movable photovoltaic bracket. Background Art

[0002] With the improvement of environmental awareness, the application of new energy, especially solar energy, has become more extensive. Solar energy is mainly collected by photovoltaic panels, and the use of photovoltaic panels to collect solar energy is inseparable from the photovoltaic panel bracket.

[0003] The photovoltaic panel brackets in the existing technology are generally fixed, which is inconvenient to use and adjust. In addition, in order to make the photovoltaic panels have a certain wind resistance and ensure that the photovoltaic panels can be stably supported, the inclination angle of the photovoltaic panels is often set to be smaller, that is, the slope of the photovoltaic panels is relatively small. In this way, when the angle of sunlight is low, the efficiency of the photovoltaic panels in collecting solar energy is low, thereby reducing the power generation efficiency of the photovoltaic panels. Summary of the Invention

[0004] In order to overcome the shortcomings of the prior art, the present invention proposes a movable photovoltaic bracket to solve the technical problems in the prior art that the photovoltaic bracket is inconvenient to use and reduces the power generation efficiency of the photovoltaic panel.

[0005] A movable photovoltaic support of the present invention adopts the following technical solution:

[0006] A movable photovoltaic bracket includes a box body consisting of a first half box and a second half box, one end of the first half box being rotatably connected to one end of the second half box so that the first half box and the second half box can swing relative to each other to open and close the box body, the axis about which the first half box and the second half box swing relative to each other being a first axis, a photovoltaic frame being provided within the box body, the photovoltaic frame being used to mount photovoltaic panels, when the box body is closed, the box body encapsulates the photovoltaic frame and the photovoltaic panels thereon to protect the photovoltaic panels, one end of the photovoltaic frame being rotatably connected to the second half box so that the photovoltaic frame can swing relative to the second half box, the axis of swing of the photovoltaic frame being a second axis, the second axis being coaxial or parallel to the first axis, and a photovoltaic support plate being further provided within the box body for supporting the photovoltaic frame in contact with the photovoltaic frame, one end of the photovoltaic support plate being rotatably connected to the second half box so that the photovoltaic support plate can swing relative to the second half box, the axis of swing of the photovoltaic support plate being a third axis, the third axis being parallel to the second axis, and the photovoltaic support plate being transmission-connected to a swing drive mechanism, the swing drive mechanism being used to drive the photovoltaic support plate to swing and maintain a set tilt angle when the box body is opened.

[0007] Further, after the photovoltaic frame is attached and supported to the photovoltaic support plate, a rotation prevention connection is provided between the photovoltaic frame and the photovoltaic support plate. One end of the photovoltaic support plate is fixed with a first rotating shaft, and the first rotating shaft is rotatably installed on the inner wall of the second half-box, so as to realize the rotational connection between one end of the photovoltaic support plate and the second half-box. A first external tooth is provided on the outer wall of the first rotating shaft. A telescopic tooth is movably arranged on the photovoltaic frame. When the photovoltaic frame is attached and supported to the photovoltaic support plate, the telescopic tooth extends out and meshes with the first external tooth on the first rotating shaft, so as to realize the rotation prevention connection between the photovoltaic frame and the photovoltaic support plate.

[0008] Further, a telescopic plate is movably installed in the photovoltaic frame. A wedge block is movably arranged on the side of the photovoltaic frame opposite to the photovoltaic support plate. One end of the telescopic plate is in contact and cooperation with the wedge block. A first elastic member is connected between the end of the telescopic plate in contact and cooperation with the wedge block and the photovoltaic frame. In the initial state, the first elastic member drives the telescopic plate to push against the wedge block. Under the pushing action of the telescopic plate, the wedge block protrudes from the lower side of the photovoltaic frame. When the photovoltaic frame is attached and supported to the photovoltaic support plate, the wedge block is squeezed by the photovoltaic support plate and retracts upward into the photovoltaic frame. Under the pushing action of the wedge block, the telescopic plate moves in a direction away from the wedge block. An iris mechanism is provided in the photovoltaic frame. The iris mechanism includes an internal gear ring, a idler gear, and a transmission gear coaxially and fixedly connected to the internal gear ring. An installation chamber for installing the iris mechanism is provided on the photovoltaic frame. The installation chamber is coaxial with the swing axis of the photovoltaic frame. The internal gear ring is rotatably installed in the installation chamber. The idler gear is eccentrically arranged in the internal gear ring and meshes with the internal gear ring for transmission. The telescopic tooth is movably inserted into the installation chamber along the radial direction of the installation chamber. A transmission rack is provided on the telescopic tooth. The transmission rack on the telescopic tooth meshes with the idler gear. One end of the telescopic plate away from the wedge block is connected with a driving rack. The driving rack meshes with the transmission gear. When the telescopic plate moves in a direction away from the wedge block, the driving rack drives the transmission gear to rotate, and the internal gear ring rotates synchronously with the transmission gear. The internal gear ring drives the telescopic tooth to extend outwards through the corresponding idler gear.

[0009] Further, a photovoltaic baffle is also provided in the box body. One end of the photovoltaic baffle is provided with a second rotating shaft. The photovoltaic baffle is rotatably installed on the inner wall of the first half-box through the second rotating shaft, so as to realize the swing connection between the photovoltaic baffle and the first half-box. The swing axis of the photovoltaic baffle is the fourth axis. The fourth axis is parallel to the third axis and the fourth axis and the third axis are symmetric about the second axis. A second external tooth is provided on the second rotating shaft. The second external tooth is in transmission meshing with the first external tooth. The photovoltaic baffle and the photovoltaic support plate are symmetrically arranged about the second axis. When the swing driving mechanism drives the photovoltaic support plate to swing, the photovoltaic baffle and the photovoltaic support plate swing in opposite directions synchronously.

[0010] Furthermore, a plurality of the idler wheels and the telescopic teeth are evenly spaced along the circumference of the inner gear ring, and the idler wheels and the telescopic teeth are arranged in a one-to-one correspondence.

[0011] Furthermore, the transmission gear and the inner ring gear are fixedly connected by a connecting rib extending radially along the inner ring gear, one end of the connecting rib is fixedly connected to the transmission gear, and the other end is fixedly connected to the inner ring gear. There are multiple connecting ribs, and the multiple connecting ribs are radially arranged with the transmission gear as the center.

[0012] Furthermore, a mounting hole is provided on the inner wall of the second half box, and the mounting hole is coaxially arranged with the swing axis of the photovoltaic frame. A friction wheel is rotatably installed in the mounting hole, and the friction wheel is coaxial with the mounting hole and the swing axis of the photovoltaic frame. The end face of the friction wheel facing the outside of the mounting hole is the friction end face, and the friction end face is frictionally matched with the side wall of the photovoltaic frame. When the photovoltaic frame swings, the photovoltaic frame drives the friction wheel to rotate.

[0013] Furthermore, a ratchet is rotatably provided in the mounting hole, and a pawl that cooperates with the ratchet is swingably provided on the inner wall of the mounting hole. The ratchet and the friction wheel are coaxially arranged, and the ratchet is located on the side of the friction wheel away from the friction end face. A torsion spring is connected between the ratchet and the friction wheel, one end of the torsion spring is fixedly connected to the ratchet, and the other end is fixedly connected to the friction wheel. When the photovoltaic frame swings in a direction away from the photovoltaic support panel, the photovoltaic frame drives the friction wheel to rotate, and the pawl prevents the ratchet from rotating, so that the torsion spring rotates and accumulates force.

[0014] Furthermore, the photovoltaic frame includes an outer square frame and a fixed plate fixed in the outer square frame, the telescopic plate is movably installed in the outer square frame, the telescopic plate and the fixed plate are in the same plane, the fixed plate and the telescopic plate are assembled to form a platform for placing the photovoltaic panel, a strip groove is formed between the telescopic plate and the fixed plate, the wedge block is installed in the strip groove, and the end of the telescopic plate opposite to the fixed plate is provided with a wedge surface that cooperates with the wedge block.

[0015] Furthermore, a mounting tube is fixed on one side of the outer square frame, the mounting chamber is located inside the mounting tube, and a radial through hole for the telescopic teeth to extend and retract and an avoidance gap for the driving rack to pass through are opened on the outer wall of the mounting tube. The driving rack passes through the avoidance gap and engages with the transmission gear located in the mounting tube for transmission.

[0016] The beneficial effects of the present invention are as follows: For a movable photovoltaic support of the present invention, by providing a box body that can be folded and buckled, when the box body is closed, the photovoltaic panel is wrapped inside the box body, which is beneficial for handling. Moreover, at night, the photovoltaic panel can be stored inside to protect the photovoltaic panel and prevent it from being damaged. At the same time, both the photovoltaic frame and the photovoltaic support plate are swingably arranged inside the box body. During use, the inclination angles of the photovoltaic frame and the photovoltaic support plate can be adjusted according to needs through a swing drive mechanism to adapt to the irradiation angle of sunlight and improve the collection efficiency of solar energy.

[0017] Furthermore, due to the special transmission method between the photovoltaic frame and the photovoltaic support plate of the present invention, when the photovoltaic frame is affected by external wind force and moves away from the photovoltaic support plate, the photovoltaic support plate can swing away from the photovoltaic frame to adjust the inclination angle smaller, thereby reducing the influence of wind force on the photovoltaic panel.

Specific embodiments

[0033] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0034] An embodiment of a movable photovoltaic support of the present invention, as Figures 1 to 13As shown, the movable photovoltaic support includes a box body 100 consisting of a first half box 105 and a second half box 106. One end of the first half box 105 is rotatably connected to one end of the second half box 106, allowing the first half box 105 and the second half box 106 to swing relative to each other, thereby opening and closing the box body 100. The axis about which the first half box 105 and the second half box 106 swing relative to each other is a first axis. In this embodiment, when the box body 100 is in the open state, the first half box 105 and the second half box 106 are arranged side by side, with the first axis extending in the front-to-back direction. A photovoltaic frame 300 is provided within the box body 100, which is used to mount photovoltaic panels. When in use, the second half box 106 is fixed at a set position, the first half box 105 can swing relative to the second half box 106, and the first half box 105 is connected to an opening and closing drive mechanism (not shown in the figure), the photovoltaic panel is installed on the photovoltaic frame 300, and then the opening and closing drive mechanism is started to open the box body 100, so that the photovoltaic panel can be used to collect solar energy. After the sun sets, the opening and closing drive mechanism closes the box body 100, and the box body 100 wraps the photovoltaic frame 300 and the photovoltaic panel on the photovoltaic frame 300 to protect the photovoltaic panel.

[0035] In the present invention, one end of the photovoltaic frame 300 is rotatably connected to the second half of the box 106, allowing the photovoltaic frame 300 to swing relative to the second half of the box 106. The photovoltaic frame 300 swings about a second axis, which is coaxial or parallel to the first axis. That is, both the first and second axes extend in the front-to-back direction. The box body 100 also includes a photovoltaic support plate 201 for supporting the photovoltaic frame 300. One end of the photovoltaic support plate 201 is rotatably connected to the second half of the box 106, allowing the photovoltaic support plate 201 to swing relative to the second half of the box 106. The photovoltaic support plate 201 swings about a third axis, which is parallel to the second axis. That is, the first, second, and third axes all extend in the left-right direction, allowing the first half of the box 105, the photovoltaic frame 300, and the photovoltaic support plate 201 to swing left and right. The photovoltaic support plate 201 is connected to a swing drive mechanism (not shown) that drives the photovoltaic support plate 201 to swing and maintain a set tilt angle when the box body 100 is opened. In this embodiment, the swing drive mechanism is connected to a control system. The control system controls the swing drive mechanism to drive the photovoltaic support panel 201 to swing according to the angle of sunlight, so as to adjust the tilt angle of the photovoltaic support panel 201 .

[0036] In this embodiment, after the photovoltaic frame 300 is attached and supported to the photovoltaic support plate 201, the photovoltaic frame 300 and the photovoltaic support plate 201 are non-rotatably connected. One end of the photovoltaic support plate 201 is fixed with a first rotating shaft, and the first rotating shaft is rotatably installed on the inner wall of the second half box 106 to realize the rotational connection between one end of the photovoltaic support plate 201 and the second half box 106. A first external gear 310 is provided on the outer wall of the first rotating shaft. A telescopic gear 306 is movably arranged on the photovoltaic frame 300. When the photovoltaic frame 300 is attached and supported to the photovoltaic support plate 201, the telescopic gear 306 extends out and meshes with the first external gear 310 on the first rotating shaft to realize the non-rotational connection between the photovoltaic frame 300 and the photovoltaic support plate 201.

[0037] In this embodiment, the photovoltaic frame 300 includes an outer peripheral square frame 314 and a fixing plate 313 fixed inside the outer peripheral square frame 314. A telescopic plate 303 is movably installed inside the outer peripheral square frame 314. The telescopic plate 303 and the fixing plate 313 are in the same plane. The fixing plate 313 and the telescopic plate 303 are joined together to form a platform for placing the photovoltaic panel. A strip-shaped groove is formed between the telescopic plate 303 and the fixing plate 313. A wedge-shaped block 301 is movably arranged on the side of the photovoltaic frame 300 opposite to the photovoltaic support plate 201. In this embodiment, the wedge-shaped block 301 is installed in the strip-shaped groove. Wedge-shaped surfaces that cooperate with the wedge-shaped block 301 are provided at the opposite ends of the telescopic plate 303 and the fixing plate 313. One end of the telescopic plate 303 is in contact and cooperation with the wedge-shaped block 301. A first elastic member 302 is connected between the end of the telescopic plate 303 in contact and cooperation with the wedge-shaped block 301 and the photovoltaic frame 300. In the initial state, the first elastic member 302 drives the telescopic plate 303 to push the wedge-shaped block 301. The wedge-shaped block 301 protrudes from the lower side of the photovoltaic frame 300 under the pushing action of the telescopic plate 303. When the photovoltaic frame 300 is attached and supported to the photovoltaic support plate 201, the wedge-shaped block 301 is squeezed by the photovoltaic support plate 201 and retracts upward into the photovoltaic frame 300. Under the pushing action of the wedge-shaped block 301, the telescopic plate 303 moves in a direction away from the wedge-shaped block 301.

[0038] In this embodiment, an iris mechanism is provided inside the photovoltaic frame 300. The iris mechanism includes an internal gear ring 304, a idler gear 305, and a transmission gear 309 fixedly connected coaxially with the internal gear ring 304. In this embodiment, the transmission gear 309 and the internal gear ring 304 are fixedly connected by connecting ribs extending radially along the internal gear ring 304. One end of the connecting rib is fixedly connected to the transmission gear 309, and the other end is fixedly connected to the internal gear ring 304. There are multiple connecting ribs, and the multiple connecting ribs are arranged radially around the transmission gear. One side of the peripheral square frame 314 is fixedly provided with an installation cylinder 312. The installation cylinder 312 has an installation chamber for installing the iris mechanism. The installation cylinder 312 and the installation chamber are coaxial with the swing axis of the photovoltaic frame 300. The internal gear ring 304 is rotatably installed in the installation chamber. The idler gear 305 is eccentrically arranged in the internal gear ring 304 and meshes with the internal gear ring 304 for transmission. The telescopic tooth 306 is movably inserted in the installation chamber along the radial direction of the installation chamber. A radial through hole for the telescopic tooth 306 to stretch is formed on the outer wall of the installation cylinder 312. A transmission rack 308 is provided on the telescopic tooth 306. The transmission rack 308 on the telescopic tooth 306 meshes with the idler gear 305. In this embodiment, multiple idler gears 305 and telescopic teeth 306 are evenly spaced along the circumferential direction of the internal gear ring 304, and the idler gears 305 and the telescopic teeth 306 are arranged in one-to-one correspondence. One end of the telescopic plate 303 away from the wedge block 301 is connected with a driving rack 307. An avoidance notch for the driving rack 307 to pass through is formed on the outer wall of the installation cylinder 312. The driving rack 307 passes through the avoidance notch and meshes with the transmission gear 309 located inside the installation cylinder 312 for transmission. When the telescopic plate 303 moves in a direction away from the wedge block 301, the driving rack 307 drives the transmission gear 309 to rotate. The internal gear ring 304 rotates synchronously with the transmission gear 309. The internal gear ring 304 drives the telescopic tooth 306 to extend outwards through the corresponding idler gear 305, so that the telescopic tooth 306 meshes with the first external teeth 310 on the first rotating shaft of the photovoltaic support plate 201, realizing the anti-rotation cooperation between the photovoltaic frame 300 and the photovoltaic support plate 201.

[0039] In this embodiment, a photovoltaic baffle 200 is further provided inside the box body 100. One end of the photovoltaic baffle 200 is provided with a second rotating shaft. The photovoltaic baffle 200 is rotatably installed on the inner wall of the first half-box 105 through the second rotating shaft, so as to realize the swing connection between the photovoltaic baffle 200 and the first half-box 105. The swing axis of the photovoltaic baffle 200 is the fourth axis. The fourth axis is arranged parallel to the third axis, and the fourth axis and the third axis are symmetric about the second axis. A second external tooth 311 is provided on the second rotating shaft. The second external tooth 311 is in transmission engagement with the first external tooth 310. The photovoltaic baffle 200 and the photovoltaic support plate 201 are symmetrically arranged left and right about the second axis. When the swing driving mechanism drives the photovoltaic support plate 201 to swing, the photovoltaic baffle 200 and the photovoltaic support plate 201 swing in opposite directions synchronously. In the present invention, the photovoltaic baffle 200 and the photovoltaic support plate 201 are symmetrically arranged left and right, and the inclination angles of the photovoltaic baffle 200 and the photovoltaic support plate 201 correspond to each other. The photovoltaic baffle 200 is located on one side of the photovoltaic frame 300 and can reflect the sun to the photovoltaic panel on the photovoltaic frame 300, improving the efficiency of the photovoltaic panel in collecting solar energy.

[0040] In this embodiment, an installation hole is formed on the inner wall of the second half-box 106. The installation hole is coaxially arranged with the swing axis of the photovoltaic frame 300. A friction wheel 104 is rotatably installed in the installation hole. The friction wheel 104 is coaxial with the installation hole and the swing axis of the photovoltaic frame 300. The end face of the friction wheel 104 facing the outside of the installation hole is a friction end face. The friction end face is in frictional transmission cooperation with the side wall of the photovoltaic frame 300. When the photovoltaic frame 300 swings, the photovoltaic frame 300 drives the friction wheel 104 to rotate.

[0041] A ratchet wheel 102 is rotatably arranged in the mounting hole, and a pawl 101 that cooperates with the ratchet wheel 102 is swingably arranged on the inner wall of the mounting hole. The ratchet wheel 102 is coaxially arranged with a friction wheel 104, and the ratchet wheel 102 is located on one side of the friction wheel 104 away from the friction end face. A torsion spring 103 is connected between the ratchet wheel 102 and the friction wheel 104. One end of the torsion spring 103 is fixedly connected to the ratchet wheel 102, and the other end is fixedly connected to the friction wheel 104. When the photovoltaic frame 300 swings away from the photovoltaic support plate 201, the photovoltaic frame 300 drives the friction wheel 104 to rotate, and the pawl 101 prevents the ratchet wheel 102 from rotating, so that the torsion spring 103 rotates and stores energy. In an outdoor environment, when the photovoltaic frame 300 is swung away from the photovoltaic support plate 201 under the action of wind, as the photovoltaic frame 300 swings away from the photovoltaic support plate 201, the photovoltaic frame 300 will drive the friction wheel 104 to rotate, while the ratchet wheel 102 cannot rotate under the blocking action of the pawl 101, and the friction wheel 104 rotates relative to the ratchet wheel 102 to store energy in the torsion spring 103. When the wind force disappears, under the action of the torsion spring 103, the photovoltaic frame 300 can swing towards the photovoltaic support plate 201 again and fit and support with the photovoltaic support plate 201. In addition, since the photovoltaic frame 300 and the photovoltaic support plate 201 are in a rotation-stopping and mating state before separation, the telescopic teeth 306 on the photovoltaic frame 300 are engaged with the first external teeth 310 on the first rotating shaft. When the photovoltaic frame 300 starts to swing away from the photovoltaic support plate 201, the swing of the photovoltaic frame 300 can drive the photovoltaic support plate 201 to swing away from the photovoltaic frame 300 (i.e., downward) by a certain angle, so that the inclination angle of the photovoltaic support plate 201 is reduced. After the photovoltaic frame 300 returns to fit and support with the photovoltaic support plate 201 under the action of the torsion spring 103, the inclination angles of both the photovoltaic frame 300 and the photovoltaic support plate 201 are reduced, so as to reduce the influence of wind force on the photovoltaic frame 300 and the photovoltaic panel.

[0042] When an adjustable photovoltaic support of the present invention is in use, a photovoltaic panel is attached and installed on a fixed plate 313 of a photovoltaic frame 300, and a second half-box 106 of a box body 100 is fixedly installed at a set position, such as on a roof, in an open space, etc. At night and during rainy and snowy weather, an opening and closing drive mechanism drives a first half-box 105 and the second half-box 106 to be buckled together, so that the box body 100 is closed, and then the photovoltaic frame 300 and the photovoltaic panel are hidden in the box body 100, thereby protecting the photovoltaic panel. During the day and on sunny days, the opening and closing drive mechanism drives the first half-box 105 to open, and the first half-box 105 and the second half-box 106 are unfolded to a 180° state, so that the box body 100 is completely opened. A swing drive mechanism drives a photovoltaic support plate 201 to swing to a set inclination angle and remain at this position. The swing drive mechanism can control the swing drive mechanism according to the irradiation angle of sunlight to drive the photovoltaic support plate 201 to swing, so as to adjust the inclination angle of the photovoltaic support plate 201, and further enable the photovoltaic panel on the photovoltaic frame 300 to adapt to the irradiation angle of sunlight, and improve the efficiency of the photovoltaic panel in collecting solar energy.

[0043] When there is wind outdoors, the photovoltaic frame 300 will be affected by the wind force. If the wind force makes the photovoltaic frame 300 fit more closely with the photovoltaic support plate 201, the inclination angle of the photovoltaic frame 300 does not need to be changed. When the photovoltaic frame 300 swings away from the photovoltaic support plate 201 under the action of the wind force, at this time, the inclination angle of the photovoltaic frame 300 needs to be adjusted smaller. The specific adjustment process is as follows: As the photovoltaic frame 300 swings away from the photovoltaic support plate 201, since the telescopic teeth 306 on the photovoltaic frame 300 are engaged with the first external teeth 310 on the first rotating shaft before the separation of the photovoltaic frame 300 and the photovoltaic support plate 201, when the photovoltaic frame 300 starts to swing away from the photovoltaic support plate 201, the swing of the photovoltaic frame 300 can drive the photovoltaic support plate 201 to swing away from the photovoltaic frame 300 (i.e., downward) by a certain angle, which will reduce the inclination angle of the photovoltaic support plate 201. And when the photovoltaic frame 300 swings away from the photovoltaic support plate 201, the photovoltaic frame 300 will drive the friction wheel 104 to rotate, while the ratchet wheel 102 cannot rotate under the blocking action of the ratchet pawl 101. The relative rotation of the friction wheel 104 with respect to the ratchet wheel 102 causes the torsion spring 103 to store energy. When the wind force disappears, under the action of the torsion spring 103, the photovoltaic frame 300 can swing back towards the photovoltaic support plate 201 and fit and support with the photovoltaic support plate 201. Since the inclination angle of the photovoltaic support plate 201 has been reduced at this time, after the photovoltaic frame 300 returns to fit and support with the photovoltaic support plate 201 under the action of the torsion spring 103, the inclination angles of both the photovoltaic frame 300 and the photovoltaic support plate 201 are reduced, which can reduce the influence of the wind force on the photovoltaic frame 300 and the photovoltaic panel. At the same time, the reduction of the inclination angle of the photovoltaic support plate 201 will also reduce the inclination angle of the photovoltaic baffle 200 to avoid affecting the photovoltaic panel's collection of solar energy.

[0044] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
