Description

Technical Field

[0001] This utility model relates to the field of solar photovoltaic power generation technology, and more specifically to a windproof solar photovoltaic panel. Background Technology

[0002] In current technology, solar photovoltaic (PV) power generation equipment is typically installed directly on the sloping surface of a roof to maximize solar energy utilization. However, this installation method poses certain safety hazards in strong winds. Because there is a gap between the PV panels and the roof, strong winds can easily enter from below, creating a lifting force that can cause the PV panels to be overturned or damaged. This phenomenon is particularly common in coastal areas or areas with strong winds.

[0003] Traditional wind protection measures typically involve adding fixing bolts or using simple support structures to enhance the stability of photovoltaic panels. However, these methods have the following problems:

[0004] Limitations of fixing bolts: Although adding fixing bolts can improve the wind resistance of photovoltaic panels, under extreme weather conditions, the bolts may loosen or break due to excessive wind force, and the risk of photovoltaic panels being overturned cannot be completely avoided.

[0005] Shortcomings of the support structure: Although the traditional support structure can provide some support, its design is relatively simple, it cannot dynamically adapt to changes in wind force, and it occupies a large space, affecting the installation flexibility of photovoltaic panels.

[0006] Separation of wind protection and power generation functions: In existing technologies, wind protection measures and photovoltaic power generation functions are designed separately, which leads to complex equipment structure, increased costs, and failure to fully utilize the power generation potential of photovoltaic panels.

[0007] Therefore, how to design a solar photovoltaic power generation device that can effectively prevent photovoltaic panels from being blown over by the wind, maintain power generation efficiency, and is also compact and flexible in installation is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0008] In view of this, the present invention provides a windproof solar photovoltaic panel, which aims to solve the technical problem that the complex windproof structure of the traditional photovoltaic power generation panel affects the power generation efficiency.

[0009] A wind-resistant solar photovoltaic panel, which can be installed on a roof slope, includes:

[0010] The main panel is rectangular and is arranged parallel to and securely connected to the roof slope.

[0011] The side panel assembly includes strip one and strip two. There are two strips one, which are symmetrically distributed on both sides along the width direction of the main panel and are rotatably connected to the edge of the corresponding main panel along the length direction of the main panel. There are two strips two, which are symmetrically distributed on both sides along the length direction of the main panel and are rotatably connected to the edge of the corresponding main panel along the width direction of the main panel.

[0012] There is a preset gap between the main panel and the roof slope. The widths of strip one and strip two are arranged corresponding to the preset gap. During the rotation of strip one and strip two, they switch between a position coplanar with the main panel and a position that blocks the preset gap.

[0013] Through the above technical solution, this utility model has strip plate one and strip plate two rotatably connected around the main panel. During the rotation of strip plate one and strip plate two, they can switch between being flush with the main panel and blocking a preset gap. When flush with the main panel, they can participate in solar power generation without affecting the power generation efficiency. When blocking the preset gap between the main panel and the roof slope, they can reduce the negative pressure formed by air flow, thereby preventing wind blowing. It has the characteristics of flexible adjustment, strong stability and adaptability, and no impact on power generation efficiency.

[0014] Preferably, it also includes a support frame, the bottom end of which is fastened to the roof slope, and the top end of which is fastened to the back of the main panel.

[0015] Preferably, it also includes an electric actuator, the fixed end of which is hinged to the support frame, and the telescopic end of which is hinged to the back of strip one or strip two.

[0016] Preferably, it also includes four arc-shaped baffles. The inner arc surface of the arc-shaped baffles is fastened to the support frame. The four arc-shaped baffles are respectively arranged corresponding to the four corner points of the main panel. The arc-shaped baffles are used to block the triangular area formed between the wide side of the first and second strips and the roof slope when the first and second strips are switched to block the preset spacing.

[0017] Preferably, the outer arc surface of the arc-shaped baffle has a circular arc transition between the upper panels of the two adjacent strips one and two.

[0018] Preferably, the support frame includes a reinforcing mesh, a base plate, and support columns. The reinforcing mesh is attached to and securely connected to the back of the main panel. Multiple base plates are arranged opposite to the nodes of the reinforcing mesh and are all securely connected to the roof slope. Multiple support columns correspond to multiple base plates and are used to connect the nodes of the base plates and the reinforcing mesh.

[0019] Preferably, it also includes a support rod, one end of which is fastened to the inner arc surface of the arc-shaped baffle, and the other end is fastened to a support column close to the arc-shaped baffle.

[0020] Preferably, both panel one and panel two are photovoltaic panels.

[0021] Preferably, it also includes a storage battery, which is connected to the main panel, strip one, and strip two via wires.

[0022] Preferably, it also includes a controller, which is electrically connected to the control modules of the multiple electric actuators, and the power supply terminals of the controller and the multiple electric actuators are all connected to the battery via wires.

[0023] As can be seen from the above technical solution, compared with the prior art, the present invention discloses a windproof solar photovoltaic panel, which has the following beneficial effects:

[0024] The design of the side panel assembly allows panel one and panel two to block the pre-set gap between the main panel and the roof slope when needed, effectively preventing strong winds from entering the pre-set gap and forming a lifting force, thereby significantly improving the wind resistance of the photovoltaic panel in strong wind weather, while not affecting the normal power generation efficiency.

[0032] The principles and features of this utility model are described below with reference to the accompanying drawings. The examples given are only for explaining this utility model and are not intended to limit the scope of this utility model.

[0033] See appendix Figure 1-6 This utility model embodiment discloses a windproof solar photovoltaic panel that can be installed on a roof slope 10, including: a main panel 1 and a side panel assembly 2;

[0034] The main panel 1 is rectangular, and the main panel 1 is arranged parallel to the roof slope 10 and is fastened to the roof slope 10.

[0035] The side panel assembly 2 includes two strips 21 and two strips 22. There are two strips 21, which are symmetrically distributed on both sides along the width direction of the main panel 1 and are rotatably connected to the edge of the corresponding main panel 1 along the length direction of the main panel 1. There are two strips 22, which are symmetrically distributed on both sides along the length direction of the main panel 1 and are rotatably connected to the edge of the corresponding main panel 1 along the width direction of the main panel 1.

[0036] There is a preset distance between the main panel 1 and the roof slope 10. The widths of strip 1 21 and strip 2 22 are arranged corresponding to the preset distance. During the rotation of strip 1 21 and strip 2 22, they switch between a position coplanar with the main panel 1 and a position that blocks the preset distance.

[0037] In some embodiments, a support frame 3 is also included, with its bottom end securely connected to the roof slope 10 and its top end securely connected to the back of the main panel 1. Thus, the addition of the support frame 3 provides additional structural support to the main panel 1, enhancing overall stability.

[0038] In other embodiments, an electric actuator 4 is also included. The fixed end of the electric actuator 4 is hinged to the support frame 3, and the telescopic end of the electric actuator 4 is hinged to the back of the first strip 21 or the second strip 22. Thus, the introduction of the electric actuator 4 enables the dynamic adjustment function of the first strip 21 or the second strip 22. Through the telescopic movement of the electric actuator 4, the position of the first strip 21 or the second strip 22 can be precisely controlled, allowing it to quickly switch to a shielding gap state when needed, or to remain coplanar with the main panel 1 during normal power generation. This achieves flexible switching between windproof and power generation functions, improving the adaptability and intelligence level of the equipment, while reducing manual intervention and enhancing ease of use.

[0039] In one embodiment, four arc-shaped baffles 5 are also included. The inner arc surface of the arc-shaped baffles 5 is fastened to the support frame 3. The four arc-shaped baffles 5 are respectively arranged corresponding to the four corner points of the main panel 1. The arc-shaped baffles 5 are used to block the triangular area formed between the wide side of the first strip 21 and the second strip 22 and the roof slope 10 when the strip 21 and the second strip 22 are switched to the blocking position at the preset gap. Thus, the design of the arc-shaped baffles 5 further optimizes the windproof effect. When the first strip 21 and the second strip 22 are switched to the blocking gap position, the arc-shaped baffles 5 can effectively block the triangular area formed between the first strip 21 and the second strip 22 and the roof slope 10, preventing strong winds from entering from these parts, further reducing the negative pressure formed by air flow, and enhancing the windproof performance. At the same time, the structural design of the arc-shaped baffles 5 helps to guide the airflow smoothly, reduce local wind pressure, and further improve the overall windproof effect.

[0040] In one embodiment, the outer arc surface of the arc-shaped baffle 5 transitions to the upper panels of two adjacent strips 21 and 22 in an arc.

[0041] In some embodiments, the support frame 3 includes a reinforcing mesh 31, a base plate 32, and support columns 33. The reinforcing mesh 31 is attached to and securely connected to the back of the main panel 1. Multiple base plates 32 are arranged opposite to the nodes of the reinforcing mesh 31 and are all securely connected to the roof slope 10. Multiple support columns 33 correspond to multiple base plates 32 to connect the nodes of the base plates 32 and the reinforcing mesh 31. Thus, by attaching and securely connecting the reinforcing mesh 31 to the back of the main panel 1, the overall structural strength of the main panel 1 is improved.

[0042] In some embodiments, a support rod 34 is also included, one end of which is fastened to the inner arc surface of the arc-shaped baffle 5, and the other end is fastened to the support column 33 near the arc-shaped baffle 5.

[0043] In this embodiment, both panel 21 and panel 22 are photovoltaic panels. Therefore, designing panels 21 and 22 as photovoltaic panels not only achieves wind protection but also increases the power generation area and improves photovoltaic power generation efficiency. This design allows the entire device to fully utilize solar energy resources while providing wind protection, further improving the energy efficiency and economy of the equipment, and achieving an organic combination of wind protection and power generation functions.

[0044] In some specific embodiments, a storage battery is also included, which is connected to the main panel 1, strip 21, and strip 22 via wires. Thus, the addition of the storage battery provides energy storage functionality for the entire device.

[0045] In some other embodiments, a controller is also included, which is electrically connected to the control modules of the plurality of electric actuators 4, and the power supply terminals of the controller and the plurality of electric actuators 4 are connected to the battery via wires.

[0046] The specific principle and usage method of the windproof, hinged solar photovoltaic panel provided in this embodiment are as follows:

[0047] 1. There is a preset gap between the main panel 1 and the roof slope 10. The strip 1 21 and the strip 2 22 are rotatably connected to the edge of the main panel 1, and can cover the preset gap when needed.

[0048] 2. When strong winds strike, the electric actuator 4 drives the first strip 21 and the second strip 22 to rotate to the blocking position, completely covering the preset gap between the main panel 1 and the roof slope 10, preventing strong winds from entering and forming a lifting force;

[0049] 3. The curved baffle 5 further shields the triangular area formed between the first strip 21 and the second strip 22 and the roof slope 10, reducing the negative pressure formed by air flow and enhancing the windproof effect.

[0050] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
