Description

Technical Field

[0001] The utility model relates to the technical field of photovoltaic installation and application, and in particular to an automatically adjustable photovoltaic carport. Background Art

[0002] The distributed carport system utilizes the planned "carport" site and replaces the original color steel and plastic roof with photovoltaic modules. It is a new application scenario suitable for distributed photovoltaic power generation systems. It does not take up more land, but can make full use of the application form of the carport. It can not only meet the basic needs of carport applications, but also combine with the basic design of facilities to realize the application of distributed local power generation and maximize the use of resources.

[0003] At present, the mainstream photovoltaic modules are basically developed around the crystalline silicon substrate. The photovoltaic modules with crystalline silicon substrate have relatively sensitive reaction characteristics to the incident angle and incident intensity of sunlight. The existing photovoltaic carports are generally fixedly installed. However, the mainstream photovoltaic modules are basically developed around the crystalline silicon substrate. The photovoltaic modules with crystalline silicon substrate have relatively sensitive reaction characteristics to the incident angle and incident intensity of sunlight. The incident angle of sunlight changes constantly during the day, and the angle between the incident angle of sunlight and the photovoltaic module will also change constantly. Technical data show that when the angle between the incident angle of sunlight and the normal line of the component surface exceeds 5 degrees, its power generation efficiency will lose about 5%; when this angle increases to 10 degrees, the power generation efficiency of the crystalline silicon photovoltaic module will lose about 15% or more; and the loss of power generation efficiency will directly cause the power generation capacity of distributed photovoltaic projects to decrease, the power generation will decrease, and the overall power generation income of the power station will be seriously affected. If the application effect is not good for a long time, the industry will abandon the application scenario such as photovoltaic carports, resulting in irreversible waste of resource development and economic investment.

[0029] The following is a detailed description of embodiments of the present invention, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments in the implementation manner are intended to be used to explain the present invention and should not be construed as limiting the present invention.

[0030] References in this specification to "one embodiment" or "an example" or "an example" mean that a particular feature, structure, or characteristic described in conjunction with the embodiment itself may be included in at least one embodiment of the present patent disclosure. The appearance of the phrase "in one embodiment" in various places in the specification does not necessarily refer to the same embodiment.

[0031] Example:

[0032] Reference Figures 1 to 5As shown, this embodiment provides an automatic adjustment photovoltaic carport, including a support mechanism 100, a photovoltaic module 200 and an angle adjustment mechanism 300. The support mechanism 100 is used to realize the basic support function of the automatic adjustment photovoltaic carport of this embodiment, and its purpose is to build the entire photovoltaic carport, which is equivalent to the bearing system of the parking carport. The photovoltaic module 200 serves as the roof of the carport, and the photovoltaic module 200 is hinged to the support mechanism 100. The angle adjustment mechanism 300 is arranged on the support mechanism 100, and the angle adjustment mechanism 300 is connected to the photovoltaic assembly 200. The angle adjustment mechanism 300 can adjust the rotation angle of the photovoltaic assembly 200 relative to the support mechanism 100 to change the inclination angle of the photovoltaic assembly 200, thereby making the angle between the light-receiving surface of the photovoltaic assembly 200 and the incident direction of the sunlight within a preset range, so that the incident angle of the sunlight and the light-receiving surface of the photovoltaic assembly 200 are always kept in a state of being perpendicular to each other or nearly perpendicular to each other, so as to achieve a better amount of sunlight absorption, so that the utility model can maximize the power generation efficiency of the roof photovoltaic system while having the function of a parking shed, ensure the power generation, and reduce the loss of power generation. A limiting portion 101 is arranged on the support mechanism 100, and the limiting portion 101 can limit the photovoltaic assembly 200 when the photovoltaic assembly 200 rotates to the initial position, so as to fix the photovoltaic assembly 200 in the initial position. It can be understood that the setting of the initial position provides a reference for the rotation angle of the photovoltaic assembly 200, which can be precisely controlled. In addition, when the intensity of solar radiation cannot support the photovoltaic assembly 200 to establish an open circuit voltage, the angle adjustment mechanism 300 will adjust the photovoltaic assembly 200 to rotate to the initial state of the carport, that is, the state when it is used as an ordinary carport.

[0033] Specifically, the limiting part 101 can adopt mechanical limiting. When mechanical limiting is adopted, the installation of the limiting part 101 is set according to the initial position of the photovoltaic component 200. The limiting part 101 can be a baffle, a block, or a limiting pin. When the photovoltaic component 200 rotates until it mechanically contacts the limiting part 101, it indicates that it has moved to the initial position. At this time, the angle adjustment mechanism 300 will stop rotating the photovoltaic component 200.

[0034] The limiter 101 can be electronically limited. When electronically limited, electronic limit elements can be installed on the support mechanism 100, such as magnetic proximity switches, photoelectric switches, etc., to limit the rotation angle of the photovoltaic module 200 in the control program. In order to ensure that the initial position is in place reliably, a redundant design can also be made, combining mechanical and electronic limits. Even if the electronic limit fails due to a fault, there is still a mechanical limit as a guarantee to ensure that the photovoltaic module 200 can move to the initial position as required.

[0035] Reference Figure 4 and Figure 5As shown, the angle adjustment mechanism 300 includes a first gear shaft 311, which is rotatably arranged on the support mechanism 100, and a plurality of first gears 312 are fixedly sleeved on the first gear shaft 311; a plurality of second gears 321 are arranged on the photovoltaic assembly 200, and the second gears 321 are meshed with the first gears 312 one by one; the first gear shaft 311 is fixedly connected to the driving motor 313, and the driving motor 313 is used to drive the first gear shaft 311 to rotate around its own axis. The driving motor 313 rotates to drive the first gear shaft 311 to rotate, and the first gear 312 on the first gear shaft 311 is meshed with the second gear 321 correspondingly, thereby driving the second gear 321 to rotate, and the second gear 321 is arranged on the photovoltaic assembly 200, thereby driving the photovoltaic assembly 200 to rotate relative to the support mechanism 100.

[0036] A plurality of bearing seats 314 are fixedly disposed on the support mechanism 100 , and the bearing seats 314 are rotatably connected to the first gear shaft 311 .

[0037] In order to improve the connection strength, a second gear shaft 322 is fixedly provided on the photovoltaic assembly 200 , and the second gear 321 is fixedly sleeved on the second gear shaft 322 .

[0038] In order to make the photovoltaic component 200 more evenly and reliably stressed, the spacing between two adjacent first gears 312 is equal, and correspondingly, the spacing between two adjacent second gears 321 is also equal. Therefore, when the photovoltaic component 200 adjusts the inclination angle under the drive of the angle adjustment mechanism 300, the size of each force point is equal.

[0039] The materials of the first gear shaft 311 , the first gear 312 , the second gear shaft 322 and the second gear 321 include, but are not limited to, stainless steel and high-strength polymer materials.

[0040] The driving motor 313 can be a servo motor or a high-precision variable frequency motor.

[0041] Reference Figure 1 and Figure 2 As shown, it can be understood that the support mechanism 100 includes a base 102 and a plurality of pillars 103. The base 102 is used to be installed and fixed with the ground foundation. A plurality of pillars 103 are arranged on the base 102 at intervals along the first direction, and the pillars 103 are provided with diagonal braces 104, and the diagonal braces 104 are arranged on one side of the plurality of pillars 103 along the first direction, and the diagonal braces 104 extend along the second direction, and the first direction intersects with the second direction. The photovoltaic module 200 is hinged to the diagonal brace 104, and the angle adjustment mechanism 300 is fixedly arranged on the diagonal brace 104. Specifically, the base 102 can be made of materials such as cement base 102 and steel base 102. The pillars 103 can be made of cement pillars 103, stainless steel pillars 103, or pillars 103 of other materials whose strength meets the design requirements.

[0042] Reference Figure 1 and Figure 2 As shown, in order to increase the number of vehicles parked in the photovoltaic carport and to improve the power generation efficiency, the automatically adjustable photovoltaic carport includes a pair of photovoltaic modules 200, which are symmetrically arranged on both sides of the plurality of pillars 103 along the first direction; each pillar 103 is provided with a pair of diagonal braces 104, and each pair of diagonal braces 104 is symmetrically arranged on both sides of the corresponding pillar 103 along the first direction. The two photovoltaic modules 200 form a gable roof in the initial state, which can adapt to rainy and snowy weather and keep the photovoltaic carport dry. It can be understood that the plurality of diagonal braces 104 are symmetrically distributed on both sides of the plurality of pillars 103 with the first direction as the symmetry reference, wherein the diagonal braces 104 located on one side of the first direction extend along the second direction, and the diagonal braces 104 located on the other side of the second direction extend along the third direction, and the third direction intersects with the first direction.

[0043] It can be understood that the pillars 103 are distributed at equal intervals along the first direction.

[0044] Reference Figures 1 to 5 As shown, it can be understood that the automatic adjustment photovoltaic carport also includes a light-chasing mechanism, which includes a first mounting rod 105 and a light tracker 106. The bottom end of the first mounting rod 105 is fixedly connected to the support mechanism 100, and the light tracker 106 is fixedly connected to the top end of the first mounting rod 105. The light tracker 106 is electrically connected to the angle adjustment mechanism 300, and the light tracker 106 is used to track and record the incident angle changes of sunlight in real time. The angle adjustment mechanism 300 can receive the incident angle information from the light-chasing mechanism, and then adjust the inclination angle of the photovoltaic module 200 in real time according to the incident angle information, so that the light-receiving surface of the photovoltaic module 200 remains vertical or nearly vertical to the incident direction of sunlight. Specifically, under the application of the automatic adjustment photovoltaic carport of this embodiment, the photovoltaic carport can automatically adjust the light-facing angle of the photovoltaic module 200 in real time according to the relationship between the sun's different latitudes, different seasons and different walking positions during the day, so that the incident angle of sunlight and the light-receiving surface of the photovoltaic module 200 are always kept perpendicular to each other or nearly perpendicular to each other, thereby adapting to the response requirements of the photovoltaic module 200 to the incident angle of the sun's incident light, improving the power generation efficiency to a certain extent, reducing the loss of power generation, and ensuring the power generation. Specifically, the angle between the light-receiving surface of the photovoltaic module 200 and the incident direction of the sunlight is precisely controlled within a preset range of 2 degrees.

[0045] Reference Figure 3 and Figure 4As shown, in order to avoid interference with the light-chasing mechanism when the photovoltaic component 200 rotates, the light-chasing mechanism also includes a second mounting rod 107, one end of the second mounting rod 107 is connected to the support mechanism 100, and the other end of the second mounting rod 107 extends along the first direction away from the support mechanism 100, and the bottom end of the first mounting rod 105 is fixedly connected to the end of the second mounting rod 107 away from the support mechanism 100. In this embodiment, the photovoltaic component 200 can rotate to any angle and the light tracker 106 can sense sunlight.

[0046] When the working place of the photovoltaic carport encounters extreme wind load, if the photovoltaic module 200 is adjusted to a tilted state with a large windward force area, the strong wind may deform the photovoltaic carport, and may even overturn the photovoltaic module 200. Therefore, a wind sensor is provided on the support mechanism 100 of the present embodiment, and the wind sensor is electrically connected to the angle adjustment mechanism 300. When the wind sensor identifies the extreme wind load, this information is transmitted to the angle adjustment mechanism 300. The angle adjustment mechanism 300 can quickly adjust the working angle of the photovoltaic module 200, reduce the windward force area of ​​the roof of the carport, and protect the working safety of the carport and the safety of its assets to the greatest extent possible. Specifically, when the wind force exceeds the wind load level 7, the angle adjustment mechanism 300 of the present embodiment should adjust the angle of the photovoltaic module 200.

[0047] In the case of extreme snow load, the angle adjustment mechanism 300 can also be controlled to adjust the angle of the photovoltaic module 200 during or after snowfall, and the photovoltaic module 200 can be adjusted to an angle that allows the snow covering the surface of the photovoltaic module 200 to slide off naturally, so as to achieve the purpose of removing the snow on the surface; when the snow is removed, the inclination angle of the photovoltaic module 200 can be adjusted according to the incident angle of sunlight to restore the optimal power generation state of the entire photovoltaic carport. This embodiment can not only remove the snow on the roof in time, reduce the pressure on the roof, and ensure the safe use of the photovoltaic carport, but also improve the power generation capacity of the photovoltaic power station.

[0048] In actual applications, the angle adjustment mechanism 300 of this embodiment can be connected to a remote control center for communication, and the remote control center can monitor the specific conditions of the photovoltaic carport in real time. In addition, the remote control center can obtain meteorological information and then set the angle adjustment instructions of the photovoltaic assembly 200 in advance according to the weather forecast to prevent strong winds or heavy snow and ensure the safety of the photovoltaic carport.

[0049] It is understandable that the automatically adjustable photovoltaic carport can be equipped with a remote controller, which is in communication with the angle adjustment mechanism 300. The angle of the photovoltaic assembly 200 can be manually adjusted through the remote controller to flexibly respond to emergencies.

[0050] It is understandable that the power source of the automatic regulating photovoltaic carport can be a self-contained battery system or the power grid on site where the carport is located.

[0051] It is understandable that all information can be transmitted through a wireless network or a wired network, and the operation of the entire system supports remote control. Wireless networks include but are not limited to 4G communication systems or 5G communication systems. Wired network systems include but are not limited to optical fibers or IoT cables.

[0052] The photovoltaic module 200 includes, but is not limited to, a crystalline silicon photovoltaic module, a perovskite photovoltaic module, and a thin-film photovoltaic module.

[0053] The above are only specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto. Those skilled in the art should understand that the present invention includes but is not limited to the contents described in the drawings and the above specific embodiments.
