Description

Technical Field

[0001] The invention relates to the technical field of photovoltaic power generation equipment, and in particular to an adjustable folding photovoltaic bracket. Background Art

[0002] In the context of energy transformation, the development and utilization of solar energy as a clean and renewable energy source has attracted much attention. Photovoltaic brackets can provide reliable support for various photovoltaic power generation projects, especially for large-scale photovoltaic power station construction with relatively flat terrain and stable lighting conditions. As an important part of the photovoltaic system, photovoltaic brackets play a key role in the stable installation and efficient power generation of photovoltaic panels.

[0003] During the transportation and installation of current photovoltaic brackets, due to their fixed structure and large size, they require a large transportation space and installation site, which increases transportation costs and installation difficulties. Moreover, once the installation is completed, it is inconvenient to carry out maintenance and repairs in the later stage. For example, when it is necessary to check the back of the photovoltaic panel or the internal components of the bracket, the operating space is limited, which increases maintenance costs and time. In addition, with the continuous expansion of the scale of photovoltaic power station construction, its installation environment is becoming increasingly diverse, including complex terrains and changeable climatic conditions such as mountainous areas and coastal areas. In these environments, existing folding photovoltaic brackets are easily affected by environmental factors. For example, in windy weather, photovoltaic panels are easily deformed or even damaged. In the face of strong winds, the gaps between the multiple photovoltaic panels that are laid flat and spliced ​​are small, and the bottom of the photovoltaic panels is usually floating, which is easy to be overturned, has poor wind resistance, and is difficult to maintain stability, which may cause damage to the photovoltaic panels during long-term use and affect their service life.

[0004] The information disclosed in the background technology section of the present invention is only intended to deepen the understanding of the general background technology of the present invention, and should not be regarded as acknowledging or suggesting in any form that the information constitutes the prior art already known to those skilled in the art.

[0007] Further, the adjustment assembly includes a connecting plate, the connecting plate is arranged between the telescopic end and the side bracket, and the side bracket is detachably connected to the telescopic end through the connecting plate; When the photovoltaic panel assembly is in an adjustment state, the side bracket moves synchronously with the telescopic end through the connecting plate; When the photovoltaic panel assembly is in a folded state, the connecting plate is separated from the side bracket.

[0008] Furthermore, a return spring is arranged between the fixing portion and the guiding portion.

[0009] Further, the support assembly includes a support column and a rotating sleeve that can rotate around its own axis, the rotating sleeve is arranged on the support column, the axis of the rotating sleeve extends in the up-down direction, the rotating sleeve has an inclined top surface, and the support plate is detachably connected to the top surface of the rotating sleeve; the telescopic member is located inside the rotating sleeve; When the photovoltaic panel assembly is in an unfolded state and an adjusted state, each of the support plates is mounted on the rotating sleeve, and the support plates are arranged around the periphery of the telescopic member.

[0010] Further, the support assembly includes a hinge structure; The number of the hinge structures is one less than the number of the support plates, and each hinge structure is connected between two adjacent support plates; When the photovoltaic panel assembly is in a folded state, one of the support plates is mounted on the rotating sleeve, and the remaining support plates are separated from the rotating sleeve and are hinged in sequence through the hinge structure.

[0011] Furthermore, the telescopic member includes a cylinder; a pressure sensor and a controller are provided between the side bracket and the telescopic end, and the pressure sensor and the cylinder are electrically connected through the controller.

[0012] Furthermore, the side bracket includes two side plates connected vertically, and each side plate is provided with a fixing hole; When the photovoltaic panel assembly is in a folded state, the side bracket is fixed to the photovoltaic panel through the fastener passing through the fixing hole; When the photovoltaic panel assembly is in an adjustment state, the fastener is removed from the fixing hole.

[0013] Furthermore, each of the support plates is provided with two positioning platforms, and the two positioning platforms are arranged on two opposite sides of the two side plates to form a limiting space; when the photovoltaic panel assembly is in an unfolded state, the side bracket is stuck in the limiting space.

[0024] like Figures 1 to 13 As shown, an embodiment of the present invention provides an adjustable folding photovoltaic support, which includes a photovoltaic panel assembly 100, an adjustment assembly 200 and a support assembly 300. The photovoltaic panel assembly 100 includes a plurality of photovoltaic panels 110 and side brackets 120, and the side brackets 120 correspond to the photovoltaic panels 110 one by one. The photovoltaic panels 110 are hingedly connected to the corresponding side brackets 120 through a first hinge structure 410.

[0025] The adjustment assembly 200 includes a telescopic member 210 having a fixed end and a telescopic end. The telescopic end can move along a telescopic direction relative to the fixed end. All side brackets 120 are detachably connected to the telescopic end of the same telescopic member 210 .

[0026] The support assembly 300 includes a support frame and a guide member 320. The support frame includes a support plate 311. The support plate 311 has a support surface 310. The telescopic member 210 is connected between the support assembly 300 and the side bracket 120. The telescopic direction of the telescopic member 210 is perpendicular to the support surface 310 of the support plate 311. The support plate 311 corresponds to the photovoltaic panel 110 one by one, and the guide member 320 corresponds to the photovoltaic panel 110 one by one. The guide member 320 includes a fixed portion 321 and a guide portion 322 that can move relatively along the guide direction. The guide member 320 is vertically arranged between the telescopic member 210, the guide direction of the guide member 320 is parallel to the support surface 310, and the guide member 320 and the telescopic member 210 are arranged in the same plane to form a guide facade. The fixed portion 321 is fixed on the support plate 311, and the photovoltaic panel 110 is hingedly connected to the guide portion 322 through the second hinge structure 420. In other embodiments, the angle between the guide member 320 and the telescopic member 210 may be other angles other than a right angle, and the guiding direction of the guide member 320 may not be parallel to the support surface 310. The telescopic direction of the telescopic member 210 is perpendicular to the support surface 310, and the guiding vertical surface where the telescopic member 210 and the guide member 320 are located is also perpendicular to the support surface 310.

[0027] The photovoltaic panel assembly 100 has an unfolded state, a folded state, and an adjustable state. Figure 5 , Figure 6 , Figure 7 As shown, when the photovoltaic panel assembly 100 is in the unfolded state, the multiple photovoltaic panels 110 in the photovoltaic panel assembly 100 are respectively attached to the corresponding support plates 311 , and the side brackets 120 corresponding to each photovoltaic panel 110 are also located on the support plates 311 .

[0028] When the photovoltaic panel assembly 100 is in a folded state, the multiple photovoltaic panels 110 in the photovoltaic panel assembly 100 are stacked in sequence, and one of the photovoltaic panels 110 can be fixed on the support surface 310 of the support plate 311 .

[0029] The embodiments of the present invention describe the spatial positional relationship between the various components from a geometric level, which facilitates the analysis and description of their movement modes (such as extension and retraction, rotation, etc.) and the coordination with other components.

[0030] When the photovoltaic panel assembly 100 is in the adjustment state, each photovoltaic panel 110 forms an angle with the corresponding support plate 311 .

[0031] Specifically, Figure 8 , Fig. 9 , Fig.10As shown, when the photovoltaic panel assembly 100 is in the adjustment state, when the telescopic member 210 is extended, that is, the telescopic end moves in the telescopic direction away from the fixed end, the first angle a of each photovoltaic panel 110 relative to the telescopic member 210 is reduced, and at the same time, the guide member 320 is shortened, that is, the guide portion 322 moves in the direction close to the fixed portion 321, and the second angle b between the photovoltaic panel 110 and the guide member 320 is increased. That is to say, for one of the photovoltaic panels 110, a part (such as one end) of the photovoltaic panel 110 is also rotated relative to the telescopic member 210 in the first rotation direction through the first hinge structure 410 when the telescopic member 210 moves telescopically; at the same time, a part (such as the other end) of the photovoltaic panel 110 is also rotated relative to the guide member 320 in the second rotation direction through the second hinge structure 420 when the guide member 320 moves. The second rotation direction is opposite to the first rotation direction, and one can be clockwise and the other can be counterclockwise.

[0032] For example, Figure 4 The positional relationship of the related components in the guide facade is shown, the trajectory of the first hinge structure 410 moving along the telescopic direction forms a straight side of the right triangle, the trajectory of the second hinge structure 420 moving along the guiding direction forms the other straight side of the right triangle, and the positive projection of the photovoltaic panel 110 in the guide facade forms the hypotenuse of the right triangle. Of course, in other embodiments, a non-right triangle can also be formed.

[0033] When the photovoltaic panel assembly 100 switches from the unfolded state to the adjusted state, each photovoltaic panel 110 swings through the first hinge structure 410 and the second hinge structure 420 respectively, so that the photovoltaic panel 110 is tilted relative to the support surface 310, that is, the photovoltaic panel 110 and the support plate 311 form a spatial intersection. In addition, since the side bracket 120 is relatively fixed to the telescopic end, the side bracket 120 is always parallel to the support surface 310, and a spatial intersection is formed between the photovoltaic panel 110 and the side bracket 120. In other words, when the photovoltaic panel assembly 100 is in the adjusted state, each photovoltaic panel 110 forms an angle with the support surface 310, that is, each photovoltaic panel 110 is tilted relative to the support plate 311. Under the constraints of the guide member 320, the telescopic member 210 and the side bracket 120, the photovoltaic panel 110 always remains perpendicular to the guide facade and will not tip over or swing.

[0034] The adjustable folding photovoltaic support provided by the embodiment of the present invention can adjust the inclination angle of the photovoltaic panel 110 according to the wind force conditions of the photovoltaic panel 110 under the driving action of the telescopic member 210 and the guiding action of the guide member 320. For example, when the photovoltaic panel assembly 100 in the unfolded state is subjected to a certain wind force, it is pushed up by the telescopic member 210, and the guide member 320 can be retracted, driving each photovoltaic panel 110 to be hinged and raised, so that the photovoltaic panel 110 and the telescopic member 210 and the guide member 320 form a triangular support mechanism. Different from the close arrangement between the multiple photovoltaic panels 110 in the unfolded state, the multiple photovoltaic panels 110 will form a larger gap after being raised, which can increase the probability of air passing. Taking the photovoltaic panel 110 in the unfolded state as an example, the photovoltaic panel 110 tilted after being raised can make the component of the wind impact force in the direction perpendicular to the photovoltaic panel 110 relatively reduced, thereby reducing the direct driving effect of the wind on the photovoltaic panel 110 and reducing the possibility of the photovoltaic panel shaking. In addition, after being raised and tilted, the photovoltaic panel 110 forms a spatial triangular support structure, which has strong stability and can effectively resist wind damage, thereby improving the wind resistance of the photovoltaic bracket, extending its service life, and expanding its scope of application.

[0035] like Figure 3 As shown, in one embodiment, the adjustment assembly 200 includes a connecting plate 220, which is arranged between the telescopic end of the telescopic member 210 and the side bracket 120, and the side bracket 120 is detachably connected to the telescopic end through the connecting plate 220. Specifically, when the photovoltaic panel assembly 100 is in the adjustment state, the connecting plate 220 is detachably fixed to the side bracket 120 by bolts, and the connecting plate 220 and the telescopic end can be detachably connected or abutted. When the telescopic end is extended, the connecting plate 220 moves synchronously with the telescopic end. When the telescopic end is retracted, the connecting plate 220 can drive the side bracket 120 back to the initial position through the reset member. Among them, the connecting plate 220 can transmit the power of the telescopic member 210, and drive the side bracket 120 to move synchronously with the telescopic end. When the photovoltaic panel assembly 100 needs to be switched to the folded state, the connecting plate 220 can be removed from the side bracket 120 to avoid interfering with the folding of the photovoltaic panel 110.

[0036] like Fig.12 As shown, in one embodiment, a return spring 330 is provided between the fixing portion 321 and the guide portion 322. When the telescopic end of the telescopic member 210 is retracted, the return spring 330 can reset the guide member 320, thereby restoring the tilted photovoltaic panel 110 to the initial flattened position.

[0037] like Fig.10As shown, in one embodiment, the support assembly 300 includes a support column 312 and a rotating sleeve 313, the rotating sleeve 313 includes a rotating motor, and under the drive of the rotating motor, the rotating sleeve 313 can rotate around its own axis, the rotating sleeve 313 is arranged on the support column 312, the axis of the rotating sleeve 313 extends in the up-down direction, the rotating sleeve 313 has an inclined top surface, and the support plate 311 is detachably connected to the top surface of the rotating sleeve 313, so that the support plate 311 is inclined relative to the horizontal plane. In addition, the first plane is parallel to the support surface 310, and the telescopic member 210 is accommodated in the interior of the rotating sleeve 313. In addition, the fixing portion 321 of the guide member 320 is fixed to the support plate 311, and the guide member 320 and the support plate 311 are arranged coplanar. With such arrangement, the rotating sleeve 313 can drive the inclined support plate 311 and the corresponding photovoltaic panel 110 to rotate together, thereby adjusting the light-facing surface of the photovoltaic panel 110, ensuring that the photovoltaic panel 110 receives sunlight at a better angle and improving power generation efficiency.

[0038] When the photovoltaic panel assembly 100 switches from the unfolded state to the adjusted state, the telescopic member 210 extends, so that the photovoltaic panel 110 tilts relative to the support plate 311 to form a triangular support mechanism. The support plate 311 can serve as the bottom plate of the triangular support mechanism and play a supporting role.

[0039] Furthermore, the support assembly 300 further includes a hinge structure 340. In the folded state, part of the support plate 311 can be separated from the rotating sleeve 313. At this time, each photovoltaic panel 110 is in contact with the support surface 310 of the corresponding support plate 311, that is, the triangular support mechanism is folded into the corresponding support plate 311. The side bracket 120 can be fixedly connected to the support plate 311, and the adjacent support plates 311 are connected by the hinge structure 340. Then, the photovoltaic panel 110 can be folded together with the corresponding support plate 311. In other embodiments, the photovoltaic panel 110 can also be separated from the support plate 311, so that the removed photovoltaic panels 110 can be stacked.

[0040] Exemplarily, the number of photovoltaic panels 110 is four, and correspondingly, the number of side brackets 120 and support plates 311 is four respectively. The number of hinge structures 340 is three. In the unfolded state and the adjusted state, the four photovoltaic panels 110 can be connected to the four support plates 311 respectively through the triangular support mechanisms in which they are located, and are arranged around the outer periphery of the telescopic member 210. In the unfolded state, the four rectangular photovoltaic panels 110 are enclosed to form a larger rectangular pattern. In the folded state, each photovoltaic panel 110 is folded together with the corresponding support plate 311. One of the support plates 311 is fixed on the rotating sleeve 313, and the other three support plates 311 are separated from the rotating sleeve 313, and each adjacent two support plates 311 of the three support plates 311 are hinged by the hinge structure 340. Among them, two hinge structures 340 arranged opposite to each other among the three hinge structures 340 are located on one side (e.g., the upper side) of the support plate 311, and the other hinge structure 340 is located on the other side (e.g., the lower side) of the support plate 311. With such arrangement, the four photovoltaic panels 110 can be folded in a "folding in half and then folding in half again" manner. Of course, in other embodiments, the first photovoltaic panel is fixed, and then the last photovoltaic panel to the previous photovoltaic panel can be hinged and stacked in sequence, wherein the number of hinge structures 340 is one less than the number of support plates 311.

[0041] Furthermore, the telescopic member 210 adopts a cylinder, and a pressure sensor and a controller are provided between the side bracket 120 and the telescopic end, and a signal connection is achieved between the pressure sensor and the cylinder through the controller.

[0042] When the photovoltaic panel 110 is blown by wind, the side bracket 120 is compressed and transmits a signal to the controller through the pressure sensor. The controller controls the movement of the cylinder. The telescopic end of the cylinder can lift the connecting plate 220, thereby driving the side bracket 120 to rise, and further driving the photovoltaic panel 110 to expand and tilt obliquely, forming a Figure 8 Adjustment status shown.

[0043] In a specific embodiment, the side bracket 120 includes two side plates 121 connected vertically, and each side plate 121 is provided with a fixing hole 122. When the photovoltaic panel assembly 100 is in a folded state, the side bracket 120 is fixed to the photovoltaic panel 110 through the fixing hole 122 by a fastener; when the photovoltaic panel assembly 100 is in an adjusted state, the fastener is removed, and the photovoltaic panel 110 is hingedly connected to the side bracket 120 through the first hinge structure 410. The fastener can be a fastening screw.

[0044] In a specific embodiment, two positioning platforms 314 are provided on the support plate 311, and the two positioning platforms 314 are arranged on opposite sides of the two side plates 121 to form a limiting space. When the photovoltaic panel assembly 100 is in the unfolded state, the side bracket 120 is inserted into the limiting space between the two positioning platforms 314. The extension directions of the two positioning platforms 314 are perpendicular, and the right-angled limiting space formed can limit the side bracket 120. In addition, a through hole is provided on the positioning platform 314, and the through hole corresponds to the fixing hole 122. When the photovoltaic panel assembly 100 is in the folded state, the side bracket 120 and the photovoltaic panel 110 can be fixed on the support plate 311 by fasteners passing through the fixing hole 122 and the through hole on the positioning platform 314.

[0045] In a specific embodiment, the first hinge structure 410 includes two ball hinges, which are respectively located on two adjacent sides of the photovoltaic panel 110. The ball hinge includes a ball head 411 and a ball connection groove 412 that cooperate with each other. The ball head 411 is fixedly mounted on the side bracket 120, and the ball connection groove 412 is set on the side of the photovoltaic panel 110. Of course, the positions of the ball head 411 and the ball connection groove 412 can be interchanged.

[0046] The second hinge structure 420 includes a hinge shaft and an axis connection hole that cooperate with each other. The hinge shaft is rotatably inserted into the axis connection hole. One of the hinge shaft and the axis connection hole is arranged at one end of the guide part 322 away from the fixed part 321, and the other is arranged on the photovoltaic panel 110. Among them, the center line of the two ball heads 411 is parallel to the axis of the hinge shaft, ensuring that the photovoltaic panel 110 can swing around two parallel rotating shafts at the same time without tipping over. Specifically, the second hinge structure 420 also includes a limiting structure to prevent relative movement between the guide member 320 and the photovoltaic panel 110 along the axial direction of the hinge shaft. The limiting structure includes a limiting plate and a limiting groove that cooperate with the axial stop along the hinge shaft. The limiting plate is arranged at one end of the guide part 322 away from the fixed part 321, and the limiting groove is arranged on the photovoltaic panel 110.

[0047] In addition, there is a clearance gap between the photovoltaic panel 110 and the corresponding side panel 121 for the first hinge structure 410 to move, so that the photovoltaic panel 110 will not be interfered by the side bracket 120 when swinging around the two ball hinges.

[0048] In a specific embodiment, each photovoltaic panel 110 is an axisymmetric structure, the symmetry axis of the photovoltaic panel 110 is coplanar with the guide member 320 and the telescopic member 210, and the symmetry axis of the photovoltaic panel 110 is perpendicular to the hinge axis. Figure 4 As shown, the symmetry axis of the photovoltaic panel 110 corresponds to the hypotenuse of the triangle.

[0049] The adjustable foldable photovoltaic support provided by the embodiment of the present invention has the following working process: The support assembly 300 is installed on the ground. The photovoltaic panel assembly 100 is switched from the folded state to the unfolded state. Specifically, after the support plate 311 and the photovoltaic panel 110 are unfolded, each support plate 311 is fixed on the inclined top surface of the rotating sleeve 313, the fastening screws at the fixing holes 122 on the side plate 121 of the side bracket 120 are removed, and then the connecting plate 220 is fixedly connected to the side bracket 120, and the connecting plate 220 is connected to the telescopic end of the telescopic member 210.

[0050] By rotating the rotating sleeve 313 , the light-facing surface of the photovoltaic panel 110 is adjusted.

[0051] When the photovoltaic panel 110 is blown by wind, the side bracket 120 is compressed, and the movement of the telescopic member 210 is controlled by the pressure sensor and the controller. The telescopic end of the telescopic member 210 can lift the connecting plate 220, thereby driving the side bracket 120 to rise, and further driving the photovoltaic panel 110 to swing obliquely, so as to achieve the following effect: Figure 8 The adjustment state shown. Through the inclination of each photovoltaic panel 110 and the space formed between the photovoltaic panels 110, the push of the wind on the photovoltaic panels 110 can be reduced, making the photovoltaic support system more stable. The unfolded photovoltaic panels 110 form a triangular support mechanism, which can withstand greater wind force and increase the applicable range of the photovoltaic panels 110. At the same time, the corresponding height of the extension of the telescopic member 210 can be controlled according to the magnitude of the induced wind force.

[0052] When the photovoltaic panel 110 is to be folded up, the connecting plate 220 is removed, and then the side bracket 120 is fixed to the photovoltaic panel 110 through the fastening screws and the fixing holes 122, and finally the photovoltaic panel 110 is folded up and placed.

[0053] In the present invention, when exposed to wind, the side bracket 120 can be pushed up by the telescopic member 210, and the guide member 320 can be retracted, driving the photovoltaic panel 110 to swing and tilt up at the same time, so that the photovoltaic panel 110 forms a triangular support mechanism. This structure can not only resist wind force, reduce the shaking of the bracket, and make the bracket more stable, but also the triangular support mechanism is less likely to bend when resisting wind force, which greatly improves the stability and reliability of the photovoltaic bracket, prolongs the service life, and expands the scope of application.

[0054] The technical features of the above embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0055] The above-described embodiments only express several implementation methods of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the present invention. It should be pointed out that, for a person of ordinary skill in the art, several modifications and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the attached claims.
