Description

TECHNICAL FIELD

[0001] The present application discloses a photovoltaic panel support technology field, especially a foldable photovoltaic panel support and photovoltaic panel device. BACKGROUND

[0002] In recent years, with the growing demand for renewable energy worldwide, solar energy has received widespread attention as a clean and sustainable energy source. Photovoltaic technology, as one of the key links in the utilization of solar energy, has developed rapidly. Photovoltaic panels have become an important means for many countries and regions to promote green energy by converting sunlight into electricity. However, to fully utilize the efficiency of photovoltaic panels, the incident angle of sunlight and the variation of sunshine time must be considered, which directly affects the power generation efficiency of photovoltaic systems. In addition, with the increase in extreme weather events caused by climate change, the stability and durability of photovoltaic systems under harsh weather conditions have also become a focus of attention.

[0003] Most photovoltaic supports on the market currently adopt fixed-angle or manual adjustment methods. Although these supports can meet the basic installation requirements, they have certain limitations in flexibility. Fixed-angle supports usually set the installation angle according to the local geographical latitude. This setting can maintain high power generation efficiency in certain seasons, but it may lead to decreased energy absorption efficiency in other periods. Maintaining a certain inclination angle on the support makes the windward surface of the photovoltaic panel larger, and in windy weather, if not adjusted in time, the wind can easily cause damage to the photovoltaic panel. Although manually adjustable supports can overcome this defect to some extent, they rely on manual adjustment, increasing the operation and maintenance cost and being inefficient. The above problems need to be solved urgently. CONTENT OF THE INVENTION

At the same time, it can also be adjusted by driving the driving piece between the first state and the second state to adjust the inclination angle of the photovoltaic panel, so as to maintain a high power generation efficiency.

[0049] Embodiment one

[0050] The present application proposes a foldable photovoltaic panel support, comprising: a first folding piece 10, a second folding piece 20, a driving piece 30; the first end of the first folding piece 10 is hinged to the bearing surface; the second end extends away from the first end; the first end of the second folding piece 20 is hinged to the second end of the first folding piece 10, forming a first hinged end 70 at the connection between the first folding piece 10 and the second folding piece 20, the second end of the second folding piece 20 extends away from the first end of the second folding piece 20, and is used to connect with one side of the photovoltaic panel; the driving piece 30 is arranged on the bearing surface in a spaced manner with the first folding piece 10, and the driving end of the driving piece 30 is connected with the first hinged end 70, so that the first hinged end 70 and the driving end move synchronously;

[0051] The driving end drives the first hinged end 70 to be close to or away from the driving member 30, so that the first folding piece 10 and the second folding piece 20 are in the first state of folding or in the second state of extension.

[0052] In the first state, the first hinged end 70 is close to the driving member 30, so that the second end of the second folding piece 20 is close to the first end of the first folding piece 10.

[0053] In the second state, the first hinged end 70 is away from the driving member 30, so that the second end of the second folding piece 20 is away from the first end of the first folding piece 10.

[0054] Specifically, the first folding piece 10 is the basis of the entire support, which is used to cooperate with the second folding piece 20 to adjust the position of the photovoltaic panel by changing the angle between them. One end of the second folding piece 20 is connected to the other end of the first folding piece 10 through hinging, and the other end is connected to one side of the photovoltaic panel. The main function of the second folding piece 20 is to directly support the photovoltaic panel and transfer the weight of the photovoltaic panel to the first folding piece 10 and the final bearing surface. Through cooperation with the first folding piece 10, the second folding piece 20 can realize the adjustment of the inclination angle of the photovoltaic panel to capture the optimal solar radiation angle.

[0055] The first folding piece 10 and the second folding piece 20 can be made of high-strength and lightweight materials such as aluminum alloy or stainless steel, etc. to ensure that the folding piece has sufficient strength to support the photovoltaic panel while facilitating folding operation. The structure of the first folding piece 10 and the second folding piece 20 can be a strip-shaped piece with a certain length, which is sufficient to support the first folding piece 10 and the second folding piece 20 to complete the folding and extension actions. The first folding piece 10 and the second folding piece 20 can also be a frame 101 surrounded by a transverse connecting piece and a longitudinal connecting piece, which has higher stability.

[0056] The bearing surface can be the ground, can be a mounting platform, can also be a roof, and can also be the base 60 of the foldable photovoltaic support. It has a bearing end surface, which can be installed with other components.

[0057] The driving member 30 can be a motor, which serves as a driving force source and converts the high-speed rotation of the motor into low-speed large torque output through a gear reduction mechanism.

[0058] The driving member 30 can also be a hydraulic cylinder or a pneumatic cylinder. In this case, the driving end is the end of the piston rod, which uses the thrust or pull force generated by hydraulic pressure or air pressure to drive the folding piece. The fixed end of the hydraulic cylinder or pneumatic cylinder is arranged on the bearing surface and hinged with the bearing surface. The driving end is inclined and hinged with the first hinged end 70.

[0059] The driving member 30 can also be an electric cylinder, which wraps a telescopic rod. After being energized, it converts electrical energy into reciprocating linear motion of the telescopic rod.

[0060] When the driving member 30 is activated, the driving end drives the first hinged end 70, i.e. the connecting point of the first folding member 10 and the second folding member 20 to move. Under the action of the driving member 30, the first hinged end 70 moves away from the driving member 30, which stretches the distance between the first end of the first folding member 10 and the second end of the second folding member 20. As a result, one side of the photovoltaic panel is lifted and tilted to better receive sunlight. Conversely, under the action of the driving member 30, the first hinged end 70 moves towards the driving member 30, which shortens the distance between the first end of the first folding member 10 and the second end of the second folding member 20. As a result, one side of the photovoltaic panel is lowered and tilted towards the bearing surface until it almost adheres to the bearing surface, thereby entering the folded state.

[0061] In some embodiments, one end of the support member 40 is hinged to the driving end, and the other end is hinged to the first hinged end 70.

[0062] Specifically, the support member 40 has a certain length and can be made of high-strength, lightweight materials such as aluminum alloy, stainless steel, or carbon fiber composite materials to ensure sufficient strength and rigidity. The two ends of the support member 40 are hinged to the first hinged end 70 and the driving end, respectively, in the form of hinges, allowing relative rotation between the components to ensure smooth folding and unfolding of the first folding member 10 and the second folding member 20. By providing the support member 40, the driving member 30 can be horizontally arranged on the bearing surface, increasing the stability of the driving member 30 during driving. Additionally, by providing additional support, the support member 40 can improve the stability of the entire system, especially in the case of strong winds or large and heavy photovoltaic panels.

[0063] When the driving member 30 is activated, the driving member 30 moves one end of the support member 40 through the driving end. Since the other end of the support member 40 is hinged to the first hinged end 70, it can cause the first hinged end 70 to move accordingly.

[0064] In the first state of folding, when the driving member 30 drives the driving end to move towards the driving member 30 body, the support member 40 will fold inward, driving the first hinged end 70 to approach the driving member 30. At this time, the angle between the first folding member 10 and the second folding member 20 decreases, and the photovoltaic panel gradually approaches the bearing surface.

[0065] In the second state of unfolding, when the driving member 30 drives the driving end to move away from the driving member 30 body, the support member 40 will unfold outward, driving the first hinged end 70 to move away from the driving member 30. At this time, the angle between the first folding member 10 and the second folding member 20 increases, and the photovoltaic panel gradually moves away from the bearing surface and can be adjusted to the optimal light receiving position according to the set angle.

[0066] In some embodiments, a transmission assembly 50 is further included, which is arranged on the bearing surface and in transmission connection with the driving member 30, and the driving member 30 is an electric motor;

[0067] The transmission assembly 50 includes a lead screw 51, one end of which is in transmission connection with the rotating shaft of the electric motor, and the other end extends towards the first folding member 10. A nut 52 is arranged to slide on the lead screw 51, and one end of the support member 40 is hingedly connected with the nut 52, and the other end is hingedly connected with the first hinge end 70.

[0068] The electric motor drives the lead screw 51 to rotate, so that the nut 52 reciprocates along the length direction of the lead screw 51, serving as the driving end of the electric motor.

[0069] Specifically, the transmission assembly 50 is used to convert the rotary motion of the electric motor into linear motion, for driving the folding and unfolding of the photovoltaic panel support.

[0070] The electric motor can be a direct current servo motor or a stepping motor, and the nut 52 is usually a ball nut 52, which is installed on the lead screw 51 and can reciprocate along the length direction of the lead screw 51

[0071] The rotating shaft of the electric motor is connected with one end of the lead screw 51 through a shaft coupling. When the electric motor rotates, the lead screw 51 also rotates, and the rotation of the lead screw 51 will cause the nut 52 to slide along the length direction of the lead screw 51. Since the nut 52 is hingedly connected with one end of the support member 40, and the other end of the support member 40 is hingedly connected with the first hinge end 70, the sliding of the nut 52 will drive the support member 40 to push and pull the first hinge end 70, thereby changing the angle between the first folding member 10 and the second folding member 20, and further realizing the folding or unfolding of the photovoltaic panel.

[0072] Bearing seats are arranged at both ends of the lead screw 51, which are arranged on the bearing surface to support the flexible rotation of the lead screw 51.

[0073] In some embodiments, the transmission assembly 50 further includes a steering device 53, which is arranged in transmission between the electric motor and the lead screw 51.

[0074] Specifically, the steering device 53 can be a right-angle steering device 53 of the electric motor. By installing the steering device 53, the axial rotation torque of the electric motor can be converted into a rotation torque perpendicular to the direction of the electric motor axis, so that the electric motor can be installed in parallel with the lead screw 51, instead of directly along the direction of the lead screw 51. Through the right-angle arrangement, space can be saved, especially in the case of limited installation space.

[0075] The motor right-angle steering gear 53 contains a pair of mutually perpendicular gear sets, usually a pair of bevel gears or worm gears. One set of gear sets rotates while the other set follows. Through reasonable layout, one motor can be used to drive multiple groups of lead screws 51 to rotate, thereby realizing the synchronous folding or stretching action of multiple foldable photovoltaic panel supports.

[0076] Among them, the motor can be a speed reducer motor group equipped with a speed reducer.

[0077] In some embodiments, a base 60 is further included, and the driving member 30 and the first folding member 10 are arranged on the base 60; the base 60 is provided with a second hinge end 80 and a third hinge end 90, the second hinge end 80 is arranged in a spaced manner with the driving member 30 and is located in the extension direction of the driving end, the first end of the first folding member 10 is connected with the second hinge end 80, the third hinge end 90 is arranged in a spaced manner with the second hinge end 80 and is close to the driving member 30, and the third hinge end 90 is used to connect with the other side opposite to one side of the photovoltaic panel.

[0078] Specifically, the base 60 serves as the foundation of the foldable photovoltaic panel support and is used to provide stable support.

[0079] The base 60 can be in the form of a frame 101 or a flat plate and can be made of high-strength materials such as steel structures, aluminum alloys or composite materials to ensure that it has sufficient load-bearing capacity and wind resistance.

[0080] The second hinge end 80 is arranged on the base 60 and is arranged in a spaced manner with the driving member 30, and can be one or a group of bearing seats, a group of bearing seats containing at least two bearing seats and being arranged in a spaced manner;

[0081] The first end of the first folding member 10 is connected with the second hinge end 80, so that the first folding member 10 can rotate at this point.

[0082] The third hinge end 90 is arranged on the base 60 and is arranged in a spaced manner with the second hinge end 80 and is close to the driving member 30. The third hinge end 90 is used to connect with the other side opposite to one side of the photovoltaic panel, so that the photovoltaic panel can be connected with the base 60 through this point, so that one side of the photovoltaic panel is connected with the second end of the second folding member 20, and the other side of the photovoltaic panel is connected with the third hinge end 90 of the base 60. When the second folding member 20 drives the photovoltaic panel to tilt, the photovoltaic panel can rotate around the third hinge end 90.

[0083] In some embodiments, the driving member 30 is a pneumatic cylinder, a hydraulic cylinder or an electric cylinder.

[0084] Specifically, the air cylinder is generally low in cost and easy to maintain. The piston rod of the air cylinder is hinged to one end of the support 40. The support 40 is driven to move by the extension and retraction of the piston rod, thereby changing the angle of the photovoltaic panel. It is suitable for occasions that are cost-sensitive and require quick response, such as frequent adjustment of the angle of the photovoltaic panel.

[0085] The hydraulic cylinder can provide high thrust and pressure, and is suitable for driving heavy photovoltaic panels. The piston rod of the hydraulic cylinder is hinged to one end of the support 40. The support 40 is driven to move by the extension and retraction of the piston rod, thereby changing the angle of the photovoltaic panel. It is suitable for occasions that require high thrust, smooth movement, and precise control, such as large photovoltaic panels or applications in windy areas.

[0086] The electric cylinder has a relatively simple structure and low maintenance cost. The piston rod of the electric cylinder is hinged to one end of the support 40. The support 40 is driven to move by the linear motion of the piston rod, thereby changing the angle of the photovoltaic panel. It is suitable for applications that require high-precision position control and energy saving.

[0087] In some embodiments, the first folding part 10 includes a first transverse connecting rod 11 and a first longitudinal connecting rod 12. The two first longitudinal connecting rods 12 are arranged opposite to each other. The first transverse connecting rod 11 passes through one end of the first longitudinal connecting rod 12 and rotates through the second hinge end 80.

[0088] The second folding part 20 includes a second transverse connecting rod 21 and a second longitudinal connecting rod 22. The two second longitudinal connecting rods 22 are arranged opposite to each other. The second transverse connecting rod 21 simultaneously rotates through one end of the two second longitudinal connecting rods 22 and the other end of the two first longitudinal connecting rods 12. The second transverse connecting rod 21 connects the ends of the first longitudinal connecting rod 12 and the second longitudinal connecting rod 22 as the first hinge end 70. The other end of the two second longitudinal connecting rods 22 is connected with another second transverse connecting rod 21.

[0089] Specifically, in order to increase the stability of the first folding part 10 and the second folding part 20, the structure of the transverse connecting rod and the longitudinal connecting rod is adopted, so that the first folding part 10 and the second folding part 20 form a frame 101 structure. After the first folding part 10 and the second folding part 20 are connected, they jointly constitute a high-efficiency and stable photovoltaic panel support.

[0090] In the first folding part 10, the first transverse connecting rod 11 passes through one end of the two first longitudinal connecting rods 12 and passes through the second hinge end 80 on the base 60, so that the first transverse connecting rod 11 can rotate in the second hinge end 80.

[0091] The two first longitudinal connecting rods 12 are connected by the first transverse connecting rod 11 to form a stable structure, while ensuring that the first longitudinal connecting rod 12 can rotate around the first transverse connecting rod 11.

[0092] In the second folding piece 20, the second transverse connecting rod 21 is inserted into one end of the two second longitudinal connecting rods 22 and the other end of the two first longitudinal connecting rods 12, so that the first longitudinal connecting rod 12 and the second longitudinal connecting rod 22 can rotate around the second transverse connecting rod 21. At this time, the second transverse connecting rod 21 serves as the first hinge end 70, and one end of the support 40 is hinged to the second transverse connecting rod 21, and the other end is connected to the driving end.

[0093] The second longitudinal connecting rods 22 are arranged in pairs and connected by the second transverse connecting rod 21, and another second transverse connecting rod 21 is inserted into the other end of the second longitudinal connecting rod 22, so that the second folding piece 20 forms a rectangular frame 101 structure, forming a stable support structure that can support the photovoltaic panel.

[0094] In the folded first state, the support 40 drives the second transverse connecting rod 21 to approach the driving member 30, the first transverse connecting rod 11 rotates around the second hinge end 80, so that the two first longitudinal connecting rods 12 approach the driving member 30, and the two second longitudinal connecting rods 22 approach the driving member 30, so that the photovoltaic panel approaches the bearing surface.

[0095] On the contrary, the support 40 drives the second transverse connecting rod 21 to move away from the driving member 30, so that the two first longitudinal connecting rods 12 expand outward, and the two second longitudinal connecting rods 22 expand outward toward the driving member 30, and finally the photovoltaic panel moves away from the bearing surface and expands to a specified angle.

[0096] In some embodiments, the end of the first longitudinal connecting rod 12 and the second longitudinal connecting rod 22 is provided with a mounting hole, and a bearing is arranged in the mounting hole.

[0097] Specifically, in order to improve the stability and flexibility during folding and unfolding, bearings are designed at the ends of the longitudinal connecting rods, which can reduce friction when the connecting rods rotate, so that the photovoltaic panel is more smooth during folding and unfolding.

[0098] Embodiment two

[0099] The present disclosure provides a photovoltaic panel device, comprising a photovoltaic panel assembly 100 and a foldable photovoltaic panel support, the foldable photovoltaic panel support comprising:

[0100] The first folding piece 10 is hinged to the bearing surface at the first end, and extends away from the first end at the second end;

[0101] The second folding piece 20 is hinged to the second end of the first folding piece 10 at the first end, and a first hinge end 70 is formed at the connection between the first folding piece 10 and the second folding piece 20. The second end of the second folding piece 20 extends away from the first end of the second folding piece 20 and is used to connect to one side of the photovoltaic panel.

[0102] The driving member 30 is arranged on the bearing surface and spaced from the first folding member 10. The driving end of the driving member 30 is connected with the first hinge end 70 to make the first hinge end 70 move synchronously with the driving end.

[0103] The driving end drives the first hinge end 70 to move close to or away from the driving member 30, so that the first folding member 10 and the second folding member 20 are in the first state of folding or the second state of stretching.

[0104] In the first state, the first hinge end 70 moves close to the driving member 30, so that the second end of the second folding member 20 moves close to the first end of the first folding member 10.

[0105] In the second state, the first hinge end 70 moves away from the driving member 30, so that the second end of the second folding member 20 moves away from the first end of the first folding member 10.

[0106] The photovoltaic panel assembly 100 is arranged on the foldable photovoltaic panel support and hinged to the second end of the second folding member 20 on one side, and extends to the direction of the driving member 30 on the other side opposite to the one side.

[0107] Specifically, the photovoltaic panel assembly 100 is a part for capturing solar energy and converting it into electrical energy. It is composed of several photovoltaic panels connected in series or parallel and encapsulated in a sturdy frame 101 to protect the photovoltaic panels from the external environment. The photovoltaic panel assembly 100 is arranged on the foldable photovoltaic panel support and hinged to the second end of the second folding member 20 on one side, and extends to the direction of the driving member 30 on the other side opposite to the one side.

[0108] The unfolding process: when the driving member 30 starts, the driving end drives the first hinge end 70 to move away from the driving member 30. The movement of the first hinge end 70 drives the second end of the second folding member 20 to extend outward. The one side of the photovoltaic panel assembly 100 rises with the movement of the second folding member 20, away from the bearing surface, until it reaches a predetermined angle.

[0109] The folding process: when the driving member 30 is started in reverse, the driving end drives the first hinge end 70 to move close to the driving member 30. The movement of the first hinge end 70 drives the second end of the second folding member 20 to contract inward. The one side of the photovoltaic panel assembly 100 folds with the movement of the second folding member 20, close to the bearing surface, until it is completely folded; the photovoltaic panel device can automatically adjust the angle of the photovoltaic panel under different light conditions to obtain the best sunlight irradiation effect. At the same time, the whole device can reduce the occupied space when not in use, improve the convenience of installation and maintenance. Not only improves the flexibility and adaptability of the photovoltaic panel device, but also enhances the stability and durability, ensures the efficient operation of the photovoltaic panel in various environments.

[0110] In some embodiments, the photovoltaic panel comprises a frame 101, the frame 101 is assembled with at least one photovoltaic panel, and the frame 101 is further provided with a mounting seat 102, the mounting seat 102 is hinged with a second end of the second folding piece 20.

[0111] Specifically, the frame 101 is usually made of metal material, such as aluminum alloy or stainless steel, the photovoltaic panel is fixedly installed on the frame 101, and the mounting seat 102 is arranged at the lower end of the frame 101. The mounting seat 102 is arranged at four corners of the lower end of the frame 101, and is respectively used for being hinged with one end of the second folding piece 20 and the third hinge end 90.

[0112] When the mounting seat 102 is hinged with one end of the second folding piece 20, when the angle of the photovoltaic panel needs to be adjusted, the inclination of the photovoltaic panel can be changed by adjusting the second folding piece 20, and at this time, the frame 101 rotates around the third hinge end 90.
