Description

Technical Field

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

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

[0003] Currently, during the transportation and installation of photovoltaic brackets, due to their fixed structure and large volume, they require a large transportation space and installation site, increasing transportation costs and installation difficulties. Moreover, once installed, subsequent maintenance and inspection are inconvenient. When it is necessary to check the back of the photovoltaic panel or the internal components of the bracket, the operating space is limited, increasing maintenance costs and time. In addition, with the continuous expansion of the scale of photovoltaic power station construction, its installation environment has become increasingly diverse, including complex terrains such as mountainous areas and coastal areas, and changing climate conditions. In these environments, existing folding photovoltaic brackets are easily significantly affected by environmental factors. For example, in strong wind weather, photovoltaic panels are easily blown deformed or even damaged. In the face of strong winds, the gaps between multiple flat-laid and joined photovoltaic panels are small, and the underside of the photovoltaic panels is usually floating, making them easily overturned, with poor wind resistance and 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 art section of the present invention is only intended to deepen the understanding of the general background art of the present invention, and should not be regarded as an admission or any form of suggestion that this information constitutes prior art known to those skilled in the art.

[0019] Further, the support assembly includes a hinge structure;

[0020] The number of the hinge structures is one less than the number of the support plates, and each of the hinge structures is connected between two adjacent support plates;

[0021] When the photovoltaic panel assembly is in a folded state, one of the support plates is installed on the rotating sleeve, and the remaining support plates are separated from the rotating sleeve and are sequentially hinged through the hinge structure.

[0022] 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 is electrically connected to the cylinder through the controller.

[0053] As Figures 1 to 13 shown, an embodiment of the present invention provides an adjustable folding photovoltaic bracket, 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. The side brackets 120 correspond to the photovoltaic panels 110 one by one, and the photovoltaic panels 110 are hingedly connected to the corresponding side brackets 120 through a first hinge structure 410.

[0054] Among them, the adjustment assembly 200 includes a telescopic member 210. The telescopic member 210 has a fixed end and a telescopic end, and the telescopic end can move relative to the fixed end along the telescopic direction. All the side brackets 120 are detachably connected to the telescopic end of the same telescopic member 210.

[0055] Among them, the support assembly 300 includes a support frame and a guide member 320. The support frame includes a support plate 311, and the support plate 311 has a support surface 310. The telescopic member 210 is connected between the support assembly 300 and the side brackets 120, and the telescopic direction of the telescopic member 210 is perpendicular to the support surface 310 of the support plate 311. The support plates 311 correspond to the photovoltaic panels 110 one by one, and the guide members 320 correspond to the photovoltaic panels 110 one by one. The guide member 320 includes a fixed portion 321 and a guide portion 322 that can move relative to each other along the guide direction. Among them, the guide member 320 is vertically arranged with respect to 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 on the same plane to form a guide vertical surface. The fixed portion 321 is fixedly arranged on the support plate 311, and the photovoltaic panel 110 is hingedly connected to the guide portion 322 through a second hinge structure 420. In other embodiments, the angle between the guide member 320 and the telescopic member 210 may also be other angles other than a right angle, and the guide 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, so the telescopic member 210 and the guide vertical surface where the guide member 320 is located are also perpendicular to the support surface 310.

[0056] Among them, the photovoltaic panel assembly 100 has a deployed state, a folded state and an adjustment state. As Figure 5 、 Figure 6 、 Figure 7As shown, when the photovoltaic panel assembly 100 is in the unfolded state, 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.

[0057] When the photovoltaic panel assembly 100 is in the folded state, 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.

[0058] The embodiments of the present invention describe the spatial position relationship between various components from a geometric level, which is convenient for analyzing and explaining their movement modes (such as expansion and contraction, rotation, etc.) and the cooperation with other components.

[0059] When the photovoltaic panel assembly 100 is in the adjustment state, each photovoltaic panel 110 forms an angle with the corresponding support plate 311.

[0060] Specifically, as Figure 8 、 Figure 9 、 Figure 10 shown, during the process of the photovoltaic panel assembly 100 being in the adjustment state, when the telescopic member 210 extends, that is, the telescopic end moves along the telescopic direction away from the fixed end, the first angle a between each photovoltaic panel 110 and the telescopic member 210 decreases, and at the same time, the guiding member 320 shortens, that is, the guiding portion 322 moves towards the fixed portion 321, and the second angle b between the photovoltaic panel 110 and the guiding member 320 increases. That is to say, for one of the photovoltaic panels 110, when a part (such as one end) of the photovoltaic panel 110 moves with the telescopic member 210 in a telescopic manner, it also rotates relative to the telescopic member 210 in the first rotation direction through the first hinge structure 410; at the same time, when a part (such as the other end) of the photovoltaic panel 110 moves with the guiding member 320 in a guiding manner, it also rotates relative to the guiding member 320 in the second rotation direction through the second hinge structure 420, where the second rotation direction is opposite to the first rotation direction, and one of them can be the clockwise direction and the other can be the counterclockwise direction.

[0061] For example, Figure 4 shows the positional relationship of related components in the guiding vertical plane. The trajectory of the first hinge structure 410 moving along the telescopic direction forms a straight side of a 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 orthographic projection of the photovoltaic panel 110 in the guiding vertical plane forms the hypotenuse of the right triangle. Of course, in other embodiments, a non - right triangle can also be formed.

[0062] 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 inclined 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. That is to say, 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 inclined relative to the support plate 311. Under the constraints of structures such as the guide member 320, the telescopic member 210, and the side bracket 120, the photovoltaic panel 110 always remains perpendicular to the guide vertical surface and will not tip over or sway.

[0063] 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 received by 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 bears a certain wind force, it is pushed up by the telescopic member 210, and at the same time, the guide member 320 can retract, driving each photovoltaic panel 110 to be hinged and raised, so that the photovoltaic panel 110 forms a triangular support mechanism with the telescopic member 210 and the guide member 320. Different from the closely arranged manner between the multiple photovoltaic panels 110 in the unfolded state, a large gap will be formed between the multiple photovoltaic panels 110 after they are raised, which can increase the probability of air passing through. Taking the wind direction perpendicular to the photovoltaic panel 110 in the unfolded state as an example, the inclined photovoltaic panel 110 after being raised can relatively reduce the component force of the wind impact force in the direction perpendicular to the photovoltaic panel 110, thereby reducing the direct pushing effect of the wind on the photovoltaic panel 110 and reducing the possibility of the photovoltaic panel shaking. In addition, the photovoltaic panel 110 forms a spatial triangular support mechanism after being raised and inclined, which has strong stability, can effectively resist the damage of wind force, improves the wind resistance performance of the photovoltaic support, extends the service life, and expands its application range.

[0064] Such as Figure 3As shown, in one embodiment, the adjusting assembly 200 includes a connecting plate 220. The connecting plate 220 is disposed between the telescopic end of the telescopic member 210 and the side bracket 120. 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 an adjusting state, the connecting plate 220 is detachably fixed to the side bracket 120 by bolts. The connection between the connecting plate 220 and the telescopic end can be either detachable or abutting. When the telescopic end extends, the connecting plate 220 moves synchronously with the telescopic end. When the telescopic end retracts, the reset member can be used to make the connecting plate 220 drive the side bracket 120 back to the initial position. 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.

[0065] As Figure 12 shown, in one embodiment, a return spring 330 is disposed between the fixing portion 321 and the guiding portion 322. When the telescopic end of the telescopic member 210 retracts, the return spring 330 can reset the guiding member 320, so that the tilted photovoltaic panel 110 returns to the initial flattened position.

[0066] As Figure 10 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. Driven by the rotating motor, the rotating sleeve 313 can rotate about its own axis. The rotating sleeve 313 is disposed on the support column 312. The axis of the rotating sleeve 313 extends in the up and down direction. The rotating sleeve 313 has an inclined top surface. 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 received inside the rotating sleeve 313. In addition, the fixing portion 321 of the guiding member 320 is fixed to the support plate 311, and the guiding member 320 and the support plate 311 are coplanarly arranged. With such a setting, the rotating sleeve 313 can drive the inclined support plate 311 and the corresponding photovoltaic panel 110 to rotate together, so as to adjust the light-facing surface of the photovoltaic panel 110, and ensure that the photovoltaic panel 110 receives sunlight at a better angle, thereby improving the power generation efficiency.

[0067] When the photovoltaic panel assembly 100 is switched from the unfolded state to the adjusting state, the telescopic member 210 extends, so that the photovoltaic panel 110 is inclined relative to the support plate 311, forming a triangular support mechanism. The support plate 311 can serve as the bottom plate of the triangular support mechanism and play a supporting role.

[0068] Further, the support assembly 300 further includes a hinge structure 340. In the folded state, a part of the support plate 311 can be separated from the rotating sleeve 313. At this time, each photovoltaic panel 110 fits against 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 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 as to stack the removed photovoltaic panels 110.

[0069] Exemplarily, the number of the photovoltaic panels 110 is four. Correspondingly, the numbers of the side brackets 120 and the support plates 311 are four respectively. The number of the hinge structures 340 is three. In the unfolded state and the adjusted state, the four photovoltaic panels 110 can be respectively connected to the four support plates 311 through the triangular support mechanisms where they are located and surround the outer periphery of the telescopic member 210. In the unfolded state, the four rectangular photovoltaic panels 110 enclose 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 every two adjacent support plates 311 among the three support plates 311 are hinged through the hinge structure 340. Among them, two relatively arranged hinge structures 340 among the three hinge structures 340 are located on one side (such as the upper side) of the support plate 311, and the other hinge structure 340 is located on the other side (such as the lower side) of the support plate 311. With such an arrangement, the four photovoltaic panels 110 can be folded in the way of "folding in half first and then folding in half again". Of course, in other embodiments, the first photovoltaic panel is fixed, and then the photovoltaic panels can be sequentially hinged and stacked from the last photovoltaic panel to the previous one. Among them, the number of the hinge structures 340 is one less than the number of the support plates 311.

[0070] Further, the telescopic member 210 is a cylinder, and a pressure sensor and a controller are arranged between the side bracket 120 and the telescopic end. The pressure sensor and the cylinder are connected through the controller for signal connection.

[0071] When the photovoltaic panel 110 is blown by wind, the side bracket 120 is pressed, and the signal is transmitted to the controller through the pressure sensor. The controller controls the movement of the cylinder, and the telescopic end of the cylinder can push up the connecting plate 220, thereby driving the side bracket 120 to rise, and further driving the photovoltaic panel 110 to be obliquely unfolded and inclined, forming an adjusted state as shown in Figure 8 shown.

[0072] In a specific embodiment, the side bracket 120 includes two side plates 121 that are vertically connected, and fixing holes 122 are provided on each side plate 121. When the photovoltaic panel assembly 100 is in the folded state, the side bracket 120 is fixed to the photovoltaic panel 110 by passing a fastener through the fixing hole 122; when the photovoltaic panel assembly 100 is in the 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.

[0073] In a specific embodiment, two positioning platforms 314 are provided on the support plate 311. The two positioning platforms 314 are arranged on the 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 snapped into the limiting space between the two positioning platforms 314. The extending directions of the two positioning platforms 314 are perpendicular, and the formed right-angled limiting space can limit the side bracket 120. In addition, through holes are provided on the positioning platforms 314, and the through holes correspond to the fixing holes 122. When the photovoltaic panel assembly 100 is in the folded state, the side bracket 120 can be fixed to the photovoltaic panel 110 on the support plate 311 by passing a fastener through the fixing hole 122 and the through hole on the positioning platform 314.

[0074] In a specific embodiment, the first hinge structure 410 includes two ball hinges. The two ball hinges are respectively located on two adjacent sides of the photovoltaic panel 110. The ball hinge includes a ball head 411 and a ball socket 412 that cooperate with each other. The ball head 411 is fixedly installed on the side bracket 120, and the ball socket 412 is provided on the side of the photovoltaic panel 110. Of course, the positions of the ball head 411 and the ball socket 412 can be interchanged.

[0075] The second hinge structure 420 includes a hinge shaft and a shaft receiving hole that cooperate with each other. The hinge shaft is rotatably inserted through the shaft receiving hole. One of the hinge shaft and the shaft receiving hole is provided at one end of the guiding portion 322 away from the fixing portion 321, and the other is provided on the photovoltaic panel 110. Among them, the central connection 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 rotation shafts simultaneously and will not tip over. Specifically, the second hinge structure 420 further includes a limiting structure to prevent relative movement between the guiding 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 are axially blocked and matched along the hinge shaft. The limiting plate is provided at one end of the guiding portion 322 away from the fixing portion 321, and the limiting groove is provided on the photovoltaic panel 110.

[0076] In addition, there is a clearance for the movement of the first hinge structure 410 between the photovoltaic panel 110 and the corresponding side plate 121, so that the photovoltaic panel 110 will not be interfered by the side bracket 120 when swinging around the two ball hinges.

[0077] 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.

[0078] The adjustable foldable photovoltaic support provided by the embodiment of the present invention has the following working process:

[0079] 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.

[0080] By rotating the rotating sleeve 313 , the light-facing surface of the photovoltaic panel 110 is adjusted.

[0081] 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.

[0082] 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.

[0083] 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.

For the sake of concise description, 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, it should be considered as the scope recorded in this specification.
