Description

Technical Field

[0001] The utility model relates to the technical field of photovoltaics, in particular to a strong wind protection device for a building-integrated photovoltaic power station. Background Art

[0002] Building-integrated photovoltaic systems are the perfect combination of solar photovoltaic systems and modern architecture. In architectural design, photovoltaic modules are installed on the exterior surface of the building structure to provide electricity, integrating the solar power generation system with the roof and other structures. On flat roofs, photovoltaic panels are typically installed with tilted brackets to better receive sunlight. In windy weather, when the wind direction is opposite to the tilt of the photovoltaic panels, the wind flows toward the raised side. At this time, the tilted design increases the contact area and prevents effective wind diversion. The wind will force the photovoltaic panels upward, posing a risk of overturning. To address this, we have designed a strong wind protection device for building-integrated photovoltaic power stations. Utility Model Content

[0003] In order to solve the technical problem that when the wind direction is opposite to the inclination direction of the photovoltaic panel, the wind cannot be effectively diverted, the wind force will cause the photovoltaic panel as a whole to have an upward force, and there is a risk of overturning, the utility model provides a strong wind protection device for a building-integrated photovoltaic power station.

[0004] The utility model adopts the following technical solution: a strong wind protection device for a building-integrated photovoltaic power station, comprising four support frames distributed in a rectangular structure, wherein the height of the two support frames on the left is lower than the two support frames on the right, a reinforcement frame is fixed between every two adjacent support frames, a mounting frame is fixed above the four support frames, and photovoltaic panels are installed on the mounting frame;

[0005] A guide plate is fixed with bolts on the right side of the mounting frame, and the lower end of the guide plate is fixed to the reinforcing frame on the right side by bolts. The guide plate is tilted downward, and a swing plate is rotatably installed between two adjacent support frames on the right side.

[0006] As a further improvement of the above solution, an upper straight plate is integrally formed above the guide plate, and a lower straight plate is integrally formed below the guide plate. The guide plate is fixed to the mounting frame and the reinforcement frame through the upper straight plate, the lower straight plate and bolts, which facilitates the installation and disassembly of the guide plate and improves convenience.

[0007] As a further improvement of the above scheme, a guide part is provided on the right side surface of the guide plate. The cross-section of the guide part is an arc-shaped structure, and the thickness of the guide part gradually increases from the front and rear ends to the middle. The middle thickness of the guide part is higher than the front and rear ends. When wind blows on the surface of the guide part, a part of it will flow up and down along the arc surface, and they can also diffuse toward the front and rear sides along the surface of the guide part, so that the force of the wind acting on the guide plate is reduced, thereby improving stability.

[0008] As a further improvement to the above solution, a connecting portion is integrally formed at the upper end of the swing plate, and a mounting shaft hole is formed through the connecting portion at the front and rear ends. A mounting shaft is rotatably sleeved in the mounting shaft hole, and the front and rear ends of the mounting shaft are respectively fixed to two support frames, so that the swing plate can deflect around the mounting shaft as the axis.

[0009] When the wind flows from left to right, the swing plate can swing to the right, reducing its contact area with the wind. When the wind flows from right to left, the swing plate swings to the left at a certain angle, so that the wind flows downward along its surface and does not contact the lower surface of the photovoltaic panel, reducing the upward force.

[0010] The middle thickness of the swing plate is higher than the thickness of the front and rear ends. When wind blows on the surface of the swing plate, part of it will flow up and down along the curved surface, and they can also diffuse toward the front and rear sides along the surface of the swing plate, so that the force of the wind acting on the swing plate is reduced.

[0011] As a further improvement of the above scheme, a limiting column is fixed between the front and rear reinforcement frames, and a sponge sleeve is sleeved on the outer ring surface of the limiting column. The limiting column is used to limit the deflection angle of the swing plate, so that when it is subjected to wind flowing to the left, the swing plate will be tilted at a certain angle by the limiting column, thereby causing the wind to flow downward, and the design of the sponge sleeve can play a buffering role, reducing the impact generated during collision. Soft rubber is also provided on the left surface of the swing plate as needed.

[0012] As a further improvement to the above solution, the bottom end of the lower straight plate of the deflector is 5-10 cm above the bottom end of the left side of the mounting frame, and the lower end of the swing plate is 5-10 cm below the bottom end of the left side of the mounting frame;

[0013] When the wind flows from left to right, most of the wind flows along the surface of the photovoltaic panel, which will exert upward and downward pressure on it. The wind flow rate flowing through the bottom of the photovoltaic panel is less than that above, and will not cause it to overturn. The swing plate can swing to the right, and the overall force is relatively small. The lower end of the guide plate is on the upper side below the mounting frame and will not come into contact with the wind. When the wind flows from right to left, the swing plate causes the wind to flow downward and will not come into contact with the bottom of the photovoltaic panel.

[0014] Compared with the prior art, the beneficial effects of the present invention are:

[0015] 1. The utility model has a guide plate fixed and tilted on the right side of the photovoltaic device, and a swing plate rotatably installed on the right side of the photovoltaic device and below the guide plate. When the wind flows from right to left, the wind will diffuse along the guide plate and the swing plate toward the upper surface, so that the wind will not directly contact the surface of the photovoltaic panel, so that the photovoltaic panel is subjected to less upward force and there is no risk of overturning upward;

[0016] 2. By setting an arc-shaped guide part on the surface of the guide plate, and the thickness of the middle part of the guide part and the swing plate is higher than the front and rear ends, the wind can diffuse toward the front and rear sides along the surface of the guide part and the swing plate, so that the force of the wind acting on the guide plate and the swing plate is reduced, thereby improving stability.

[0023] Below, the present invention is further described in conjunction with the accompanying drawings and specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0024] Example:

[0025] Please combine Figures 1-4The strong wind protection device for a building-integrated photovoltaic power station of this embodiment is characterized by comprising four support frames 1 distributed in a rectangular structure, wherein the height of the two support frames 1 on the left is lower than the two support frames 1 on the right, a reinforcement frame 11 is fixed between every two adjacent support frames 1, a mounting frame 2 is fixed above the four support frames 1, and a photovoltaic panel 3 is mounted on the mounting frame 2;

[0026] A guide plate 4 is fixed to the right side of the mounting frame 2 by bolts. The lower end of the guide plate 4 is fixed to the reinforcing frame 11 on the right side by bolts. The guide plate 4 is tilted downward. A swing plate 5 is rotatably installed between two adjacent support frames 1 on the right side.

[0027] An upper straight plate 43 is integrally formed above the guide plate 4, and a lower straight plate 42 is integrally formed below the guide plate 4. The guide plate 4 is fixed to the mounting frame 2 and the reinforcement frame 11 through the upper straight plate 43, the lower straight plate 42 and bolts, which facilitates the installation and disassembly of the guide plate 4 and improves convenience.

[0028] A guide portion 41 is provided on the right side surface of the guide plate 4. The cross-section of the guide portion 41 is an arc-shaped structure, and the thickness of the guide portion 41 gradually increases from the front and rear ends to the middle. The thickness in the middle of the guide portion 41 is higher than the front and rear ends. When wind blows on the surface of the guide portion 41, a part of it will flow up and down along the arc surface, and they can also diffuse toward the front and rear sides along the surface of the guide portion 41, so that the force of the wind acting on the guide plate 4 is reduced, thereby improving stability.

[0029] The upper end of the swing plate 5 is integrally formed with a connecting portion 51, and the connecting portion 51 is penetrated by a mounting shaft hole 52 at its front and rear ends. A mounting shaft 6 is rotatably sleeved in the mounting shaft hole 52. The front and rear ends of the mounting shaft 6 are respectively fixed to the two support frames 1. The swing plate 5 can deflect about the mounting shaft 6 as the axis.

[0030] When the wind flows from left to right, the swing plate 5 can swing to the right, reducing its contact area with the wind. When the wind flows from right to left, the swing plate 5 swings to the left at a certain angle, so that the wind flows downward along its surface and does not contact the lower surface of the photovoltaic panel 3, reducing the upward force.

[0031] The middle thickness of the swing plate 5 is higher than the thickness of the front and rear ends. When the wind blows on the surface of the swing plate 5, part of it will flow up and down along the curved surface, and they can also diffuse toward the front and rear sides along the surface of the swing plate 5, so that the force of the wind acting on the swing plate 5 is reduced.

[0032] A limiting column 7 is fixed between the front and rear reinforcement frames 11. The outer ring surface of the limiting column 7 is sleeved with a sponge cover 71. The limiting column 7 is used to limit the deflection angle of the swing plate 5, so that when it is subjected to wind flowing to the left, the swing plate 5 will be tilted at a certain angle by the limiting column 7, thereby causing the wind to flow downward, and the design of the sponge cover 71 can play a buffering role, reducing the impact caused by the collision. Soft rubber is also provided on the left surface of the swing plate 5 as needed.

[0033] The bottom end of the lower straight plate 42 of the guide plate 4 is 5-10 cm above the bottom end of the left side of the mounting frame 2, and the lower end of the swing plate 5 is 5-10 cm below the bottom end of the left side of the mounting frame 2;

[0034] When the wind flows from left to right, most of the wind flows along the surface of the photovoltaic panel 3, which will exert an upward and downward pressure on it. The wind flow rate flowing through the bottom of the photovoltaic panel 3 is less than that above, and will not cause it to overturn. The swing plate 5 can swing to the right, and the overall force is small. The lower end of the guide plate 4 is on the upper side below the mounting frame 2 and will not come into contact with the wind. When it is affected by the wind flowing from right to left, the swing plate 5 causes the wind to flow downward and will not come into contact with the bottom of the photovoltaic panel 3.

[0035] The implementation principle of a strong wind protection device for a building-integrated photovoltaic power station in the embodiment of the present application is as follows: in actual use, the photovoltaic panel 3 is fixed to the roof through the support frame 1 and the mounting frame 2, and the deflector 4 and the swing plate 5 are both installed on the right side of the mounting frame 2 and the support frame 1;

[0036] When the photovoltaic panel 3 is subjected to a strong wind flowing from left to right, since the photovoltaic panel 3 is installed at an angle and its left end is lower than the right end, most of the wind flows along the surface of the photovoltaic panel 3, which will exert a downward pressure on its upper surface. At this time, the wind flow rate flowing through the bottom of the photovoltaic panel 3 is smaller than that flowing through the top, so it will not overturn. Moreover, the swing plate 5 can swing to the right, and the overall force is small. Moreover, the lower end of the guide plate 4 is located on the upper side below the mounting frame 2 and will not be exposed to the wind.

[0037] When the photovoltaic panel 3 is subjected to a strong wind flowing from right to left, the wind will blow on the surface of the guide plate 4. Since the guide portion 41 is provided on the right side surface of the guide plate 4, and the cross-section of the guide portion 41 is an arc-shaped structure, and the thickness of the middle of the guide portion 41 is higher than the front and rear ends, when the wind blows on the surface of the guide portion 41, a part of it will flow up and down along the arc surface, and the wind will also spread to the front and rear sides along the surface of the guide portion 41. The wind that spreads upward and to the front and rear sides will flow out of its surface.

[0038] The downward-flowing wind will contact the swing plate 5 and be guided by the swing plate 5 so that part of it will flow downward and part of it will spread to the front and rear sides. The lower end of the guide plate 4 is located below and above the mounting frame 2, which prevents the wind from directly contacting the surface of the photovoltaic panel 3. As a result, the photovoltaic panel 3 is subjected to less upward force and does not have the risk of overturning upward.

[0039] By fixing the guide plate 4 at an angle on the right side of the photovoltaic device, and rotating the swing plate 5 on the right side of the photovoltaic device and below the guide plate 4, when the wind flows from right to left, the wind will diffuse along the guide plate 4 and the swing plate 5 toward the upper surface, so that the wind will not directly contact the surface of the photovoltaic panel 3, so that the photovoltaic panel 3 is subjected to less upward force and there is no risk of overturning upward;

[0040] By providing an arc-shaped guide portion 41 on the surface of the guide plate 4, and the thickness of the middle part of the guide portion 41 and the swing plate 5 is higher than the front and rear ends, the wind can diffuse toward the front and rear sides along the surface of the guide portion 41 and the swing plate 5, so that the force of the wind acting on the guide plate 4 and the swing plate 5 is reduced, thereby improving stability.

[0041] The above-mentioned embodiments are only preferred embodiments of the present invention and cannot be used to limit the scope of protection of the present invention. Any non-substantial changes and replacements made by technicians in this field on the basis of the present invention fall within the scope of protection required by the present invention.
