Description

Technical Field

[0001] The utility model relates to the technical field of photovoltaics, in particular to a photovoltaic panel bracket for a roof. Background Art

[0002] Photovoltaic power generation is a technology that uses the photovoltaic effect of semiconductor interfaces to directly convert light energy into electrical energy. It is mainly composed of three parts: solar panels (modules), controllers and inverters. The main components are made of electronic components. Solar cells are packaged and protected after being connected in series to form large-area solar cell modules, which are then combined with power controllers and other components to form photovoltaic power generation devices.

[0003] Existing rooftop photovoltaic panel supports generally rely on their own weight to stabilize the photovoltaic panels when strong winds hit, preventing the photovoltaic panels from being blown away. Under long-term or extreme wind conditions, these support points may be damaged due to excessive force, thereby affecting the integrity and service life of the photovoltaic panels. Utility Model Content

[0004] Based on this, the purpose of the utility model is to provide a photovoltaic panel bracket for a roof to solve the technical problem that these supporting points may be damaged due to excessive force under long-term or extreme wind conditions.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a photovoltaic panel bracket for a roof, comprising a base, the top of the base is fixedly connected to an outer rod, the inner part of the outer rod is slidably connected to an inner rod, the inner rod is connected to a support plate through a ball joint, the support plate is fixedly connected to guide plates around, wing panels are arranged between the four guide plates, and the bottom of the wing panel is an arc-shaped structure.

[0006] By adopting the above technical solution, the roof photovoltaic panel bracket realizes stable support of the photovoltaic panel on the roof through the combined design of the base, the outer rod, the inner rod and the support plate. The inner rod is slidably connected inside the outer rod, so that the height of the support plate can be adjusted to meet the requirements of different roof heights and inclinations. The structure of the guide plate and the wing panel is utilized to achieve effective diversion and utilization of wind force, improve the stability of the photovoltaic panel bracket, and effectively prevent the risk of the photovoltaic panel being blown away in strong wind weather.

[0007] Furthermore, the guide plate is coated with a hydrophobic layer.

[0008] By adopting the above technical solution, by coating the hydrophobic layer on the guide plate, the adhesion of rainwater on the surface of the guide plate can be effectively reduced, making it easier for rainwater to form water droplets on the guide plate and roll down quickly, rather than staying on the plate surface to form a water film.

[0009] Furthermore, a mounting groove is provided inside the support plate, a photovoltaic panel is arranged inside the mounting groove, and a controller is fixedly connected to the bottom of the photovoltaic panel.

[0010] By adopting the above technical solution, by opening a mounting groove inside the support plate, a stable and safe installation position is provided for the photovoltaic panel, ensuring that the photovoltaic panel can be firmly fixed on the bracket and is not easy to fall off or be damaged even in strong winds or bad weather conditions.

[0011] Furthermore, cards are rotatably connected to the corners of the support plate, and four cards are provided, and the four cards are all in a fan-shaped structure.

[0012] By adopting the above technical solution, by rotating the cards connecting the four fan-shaped structures at the corners of the support plate, the edges around the photovoltaic panel can be engaged and protected, preventing the photovoltaic panel from falling off during use, thereby extending the service life of the photovoltaic panel.

[0013] Furthermore, four outer rods and four inner rods are provided, and the four outer rods and the four inner rods are provided in a rectangular structure.

[0014] By adopting the above technical solution, by setting four outer rods and inner rods and arranging them in a rectangular structure, the stability and load-bearing capacity of the entire photovoltaic panel bracket can be significantly enhanced, so that the photovoltaic panel has balanced support in four directions, effectively preventing deformation or tilting caused by wind, gravity or other external forces.

[0015] Furthermore, pin holes are provided on the four outer rods and the inner rod, and latch pins are engaged inside the pin holes.

[0016] By adopting the above technical solution, by opening pin holes on the four outer rods and the inner rod and engaging the pins inside the pin holes, the inner rod can be easily fixed and adjusted in the outer rod, so that the height of the support plate can be flexibly adjusted according to actual needs to adapt to the installation requirements of roofs with different heights and inclinations.

[0017] Furthermore, an empty slot is provided on the outer rod, and one side of the outer rod is rotatably connected to a locking mechanism via a torsion shaft.

[0018] By adopting the above technical solution, by opening a slot on the outer rod, a space is provided for the locking mechanism to engage with the inner rod, so that the locking mechanism can be tightly engaged with the inner rod to form an engaging structure.

[0019] Furthermore, the locking mechanism comprises a mounting block, a fin is fixedly connected to the top of the mounting block, and a ratchet is fixedly connected to one side of the mounting block.

[0020] By adopting the above technical solution, the mounting block in the locking mechanism provides a stable mounting base for the fins and ratchets, ensuring the structural firmness of the entire locking mechanism, so that the locking mechanism can remain stable when subjected to external forces such as wind and is not easily damaged or failed.

[0021] Furthermore, a tooth groove is provided on one side of the inner rod, and a plurality of the tooth grooves are provided, and the plurality of tooth grooves are linearly and equidistantly arranged.

[0022] By adopting the above technical solution, a plurality of linearly equidistantly arranged tooth grooves are opened on one side of the inner rod, which provides a reliable engagement position for the ratchet, so that the locking mechanism can be firmly fixed on the inner rod in the locked state to prevent it from sliding or displacing due to wind or other external forces.

[0023] Furthermore, the ratchet teeth and tooth grooves are matched.

[0024] By adopting the above technical solution, the matching design of the ratchet and the tooth groove enables the locking mechanism to tightly engage with the inner rod, effectively preventing the inner rod from sliding freely inside the outer rod, and ensuring the stability of the bracket during use.

[0025] In summary, the utility model mainly has the following beneficial effects:

[0026] 1. The utility model can press the photovoltaic panel against the roof by setting the base, guide plate and wing panel, effectively preventing the connection position from being broken due to excessive wind force, thereby avoiding the risk of the photovoltaic panel being blown away, and providing a strong guarantee for the long-term stable operation of the photovoltaic system;

[0027] 2. The utility model realizes effective diversion and anti-penetration of rainwater by setting the guide plate and the hydrophobic layer, thereby avoiding the continuous flow of rainwater on the surface of the photovoltaic panel due to surface tension, and further preventing the risk of water intrusion into the internal controller;

[0028] 3. The utility model cleverly realizes the function of automatically lowering the height in strong winds by setting a locking mechanism, thereby effectively reducing the windward area and wind resistance of the photovoltaic panel and significantly improving the wind resistance of the photovoltaic system.

DETAILED DESCRIPTION

[0034] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. The embodiments described below with reference to the drawings are exemplary and are only used to explain the utility model, and cannot be understood as limiting the utility model.

[0035] The following describes an embodiment of the utility model based on its overall structure.

[0036] Embodiment 1:

[0037] A photovoltaic panel support for a roof, such as Figure 1-Figure 4 As shown, it includes a base 1, the top of the base 1 is fixedly connected to an outer rod 2, the inner rod 3 is slidably connected to the inner part of the outer rod 2, the inner rod 3 is connected to a support plate 5 through a ball joint 4, the support plate 5 is fixedly connected to a guide plate 6 around, a wing panel 7 is arranged between the four guide plates 6, and the bottom of the wing panel 7 is an arc-shaped structure. The photovoltaic panel bracket for the roof realizes stable support of the photovoltaic panel 9 on the roof through the combined design of the base 1, the outer rod 2, the inner rod 3 and the support plate 5, and the inner rod 3 is slidably connected inside the outer rod 2, so that the height of the support plate 5 can be adjusted to adapt to different roof heights. In order to meet the requirements of degree and inclination, the structure of the guide plate 6 and the wing panel 7 is utilized to realize the effective diversion and utilization of wind force. Under the action of wind force, the guide plate 6 divides the wind force into two streams, one of which enters the inside of the wing panel 7, and the other flows through the surface of the photovoltaic panel 9. According to Bernoulli's theorem, the pressure under the wing panel 7 is relatively small, while the pressure on the surface of the photovoltaic panel 9 is relatively large, thereby generating a force that presses the photovoltaic panel 9 against the roof, enhancing the wind resistance of the bracket, improving the stability of the photovoltaic panel bracket, and effectively preventing the risk of the photovoltaic panel 9 being blown away in strong wind weather.

[0038] See also Figure 1 , Figure 2 and Figure 3The guide plate 6 is coated with a hydrophobic layer. By coating the guide plate 6 with the hydrophobic layer, the adhesion of rainwater on the surface of the guide plate 6 can be effectively reduced, making it easier for rainwater to form water droplets on the guide plate 6 and roll down quickly, rather than staying on the plate surface to form a water film. At the same time, because the rainwater is effectively diverted, the controller 10 inside the photovoltaic panel 9 is not easily burned due to water ingress, thereby improving the service life.

[0039] See also Figure 1 , Figure 2 and Figure 3 A mounting groove 8 is provided inside the support plate 5, and a photovoltaic panel 9 is arranged inside the mounting groove 8. A controller 10 is fixedly connected to the bottom of the photovoltaic panel 9. By providing the mounting groove 8 inside the support plate 5, a stable and safe installation position is provided for the photovoltaic panel 9, ensuring that the photovoltaic panel 9 can be firmly fixed on the bracket and is not easy to fall off or be damaged even in strong winds or bad weather conditions. At the same time, fixing the controller 10 at the bottom of the photovoltaic panel 9 not only saves space, but also enables the controller 10 to be tightly integrated with the photovoltaic panel 9, which is convenient for management and maintenance.

[0040] See also Figure 1 , Figure 2 and Figure 3 A card 11 is rotatably connected to the corners of the support plate 5. Four cards 11 are provided, and each of the four cards 11 is in a fan-shaped structure. By rotatably connecting the four fan-shaped cards 11 at the corners of the support plate 5, the edges around the photovoltaic panel 9 can be engaged and protected, preventing the photovoltaic panel 9 from falling off during use, thereby extending the service life of the photovoltaic panel 9. At the same time, the fan-shaped structure design of the cards 11 enables them to fit tightly at the corners of the photovoltaic panel 9, providing more comprehensive protection.

[0041] See also Figure 1 , Figure 2 and Figure 3 There are four outer rods 2 and inner rods 3, and the four outer rods 2 and inner rods 3 are arranged in a rectangular structure. By setting four outer rods 2 and inner rods 3 and arranging them in a rectangular structure, the stability and load-bearing capacity of the entire photovoltaic panel bracket can be significantly enhanced, so that the photovoltaic panel 9 has balanced support in four directions, effectively preventing deformation or tilting caused by wind, gravity or other external forces. At the same time, since the four outer rods 2 and inner rods 3 are independent of each other and adjustable, they can be flexibly arranged according to the actual size and shape of the roof, maximizing the use of available space and ensuring that the installation position and angle of the photovoltaic panel 9 are optimal.

[0042] See also Figure 1 , Figure 2 and Figure 3, pin holes 12 are provided on the four outer rods 2 and the inner rod 3, and latches 13 are engaged inside the pin holes 12. By providing pin holes 12 on the four outer rods 2 and the inner rod 3 and engaging the latches 13 inside the pin holes 12, the inner rod 3 in the outer rod 2 can be conveniently fixed and adjusted, so that the height of the support plate 5 can be flexibly adjusted according to actual needs to adapt to the installation requirements of roofs with different heights and inclinations. At the same time, the engaging connection between the latch 13 and the pin hole 12 also enhances the stability and safety of the entire bracket. The latch 13 can effectively prevent the inner rod 3 from sliding or falling off in the outer rod 2, ensuring that the photovoltaic panel 9 can maintain a stable position and angle after installation, and will not move or tilt due to wind or other external forces.

[0043] The implementation principle of the utility model is as follows: first, after the support plate 5 is lifted to a suitable position, the plug 13 is inserted into the pin hole 12 to complete the fixation of the photovoltaic panel 9. When a typhoon occurs, the wind blows from one side of the photovoltaic panel 9, and is divided into two streams through the guide plate 6. One stream enters the wing panel 7 below the photovoltaic panel 9, and the other stream flows through the surface of the photovoltaic panel 9. According to Bernoulli's theorem, the wing panel 7 has a long path, resulting in a smaller pressure below the wing panel 7 and a larger pressure on the surface of the photovoltaic panel 9, so that the photovoltaic panel 9 can be pressed against the roof to prevent the connection position from being broken due to excessive wind force, causing the photovoltaic panel 9 to be blown away;

[0044] The hydrophobic layer on the guide plate 6 can prevent rainwater from continuing to flow on the surface due to surface tension when it flows down the guide plate 6 .

[0045] Embodiment 2:

[0046] See also Figure 4 The outer rod 2 is provided with an empty slot 14, and one side of the outer rod 2 is rotatably connected with a locking mechanism 15 through a torsion shaft. By providing the empty slot 14 on the outer rod 2, a space is provided for the locking mechanism 15 to engage with the inner rod 3, so that the locking mechanism 15 can be tightly engaged with the inner rod 3 to form an engaging structure. At the same time, the outer rod 2 is rotatably connected with the locking mechanism 15 through the torsion shaft, so that the locking mechanism 15 can be flexibly rotated when needed to achieve locking or unlocking of the inner rod 3. The design of the torsion shaft provides a certain resistance for the locking mechanism 15, ensuring that when the wind force is small, the locking mechanism 15 can maintain the locked state of the inner rod 3 to prevent the inner rod 3 from accidentally sliding. When the wind force is too strong, the locking mechanism 15 can rotate in response to the change in wind force, unlock the inner rod 3, and allow it to slide down to reduce the windward area, thereby reducing wind resistance and protecting the photovoltaic panel 9 from being blown away.

[0047] See also Figure 4The locking mechanism 15 includes a mounting block 151, a fin 152 is fixedly connected to the top of the mounting block 151, and a ratchet 153 is fixedly connected to one side of the mounting block 151. The mounting block 151 in the locking mechanism 15 provides a stable mounting base for the fin 152 and the ratchet 153, ensuring the structural firmness of the entire locking mechanism 15, so that the locking mechanism 15 can remain stable when subjected to external forces such as wind, and is not easily damaged or failed. At the same time, the special shape and structure of the fin 152 enable it to generate an outward force under the action of wind. When this force is greater than the resistance provided by the torsion shaft, the mounting block 151 will drive the ratchet 153 to rotate, thereby realizing the unlocking function of the locking mechanism 15.

[0048] See also Figure 4 A tooth groove 154 is provided on one side of the inner rod 3, and a plurality of tooth grooves 154 are provided. The plurality of tooth grooves 154 are linearly and equidistantly arranged. By providing a plurality of linearly and equidistantly arranged tooth grooves 154 on one side of the inner rod 3, a reliable engagement position is provided for the ratchet 153, so that the locking mechanism 15 can be firmly fixed on the inner rod 3 in the locked state to prevent it from sliding or displacing due to wind or other external forces. At the same time, the linearly and equidistant arrangement of the plurality of tooth grooves 154 also provides a precise adjustment range for the sliding of the inner rod 3 in the outer rod 2. By selecting different tooth grooves 154 to engage with the ratchet 153, the height and angle of the support plate 5 can be precisely adjusted to meet the installation requirements of different roofs.

[0049] See also Figure 4 The ratchet 153 and the tooth groove 154 are adapted to each other. The adapted design of the ratchet 153 and the tooth groove 154 enables the locking mechanism 15 to be tightly engaged with the inner rod 3, effectively preventing the inner rod 3 from sliding randomly inside the outer rod 2, thereby ensuring the stability of the bracket during use. At the same time, due to the precise matching of the ratchet 153 and the tooth groove 154, the bracket can be accurately positioned when the height is adjusted. When the angle or height of the photovoltaic panel needs to be adjusted, the user only needs to lift the locking mechanism 15 to disengage the ratchet 153 from the currently engaged tooth groove 154, and then slide the inner rod 3 to the appropriate position, and then lower the locking mechanism 15 to enable the ratchet 153 to engage with the new tooth groove 154, thereby improving the adjustment accuracy and convenience of the bracket.

[0050] The implementation principle of the utility model is: first, when the wind speed is too high, the wind blows through the fin 152, so that the pressure on the outside of the fin 152 is less than the pressure on the inside, thereby generating an outward force. When the outward force is greater than the force provided by the torque shaft, the mounting block 151 rotates, so that the ratchet 153 and the tooth groove 154 are disengaged, and the inner rod 3 can slide to the bottom along the outer rod 2, reducing the windward area, reducing wind resistance, and preventing the photovoltaic panel 9 from being blown away.

[0051] Parts not involved in the present invention are the same as the prior art or can be implemented by using the prior art, and will not be described in detail here.

The specific features, structures, materials or characteristics described may be combined in a suitable manner in any one or more embodiments or examples.
