Description

Technical Field

[0001] This utility model relates to the field of photovoltaic equipment, specifically a wind-resistant reinforcement structure for photovoltaic modules. Background Technology

[0002] In the current trend of energy transition, solar energy, as a clean and renewable energy source, is being utilized on an ever-expanding scale. Photovoltaic modules, as the core component of solar photovoltaic power generation systems, are widely used in various ground-mounted power plants, rooftop distributed power generation projects, and independent power supply systems in remote areas.

[0003] Regardless of the environment in which photovoltaic modules are installed, they must be laid on pre-installed brackets and positioned at the optimal angle for receiving sunlight, i.e., the photovoltaic modules must be tilted.

[0004] However, wind, as a common and complex natural climate factor, poses a severe challenge to the stable operation of photovoltaic (PV) modules. For example, in many regions, especially coastal areas, plateaus, and windy inland areas, strong winds frequently occur. These strong winds often impact PV modules, which are typically tilted, resulting in a larger contact area with the wind and consequently, varying degrees of damage. Reducing the tilt angle of the PV modules would decrease the damage caused by wind.

[0005] Increased wind speed not only generates strong horizontal thrust, causing photovoltaic modules to shift on their supporting structures, but also creates a pressure difference on the module surface due to Bernoulli's principle, resulting in an upward suction force on the modules. Currently, most supports for photovoltaic modules are made of angle iron, whose strength needs improvement; therefore, they are highly susceptible to bending under strong winds. Utility Model Content

[0006] The purpose of this utility model is to provide a wind-resistant reinforcement structure for photovoltaic modules, which aims to improve the situation where the photovoltaic modules are tilted and the strength of the brackets supporting the photovoltaic modules needs to be improved, so that the photovoltaic modules may change their state due to excessive force in strong winds.

[0007] This utility model is implemented as follows: A wind-resistant reinforcement structure for photovoltaic modules includes support legs, with triangular frames mounted on the support legs. The bottom of the triangular frames is fitted onto an adjustment mechanism, which is mounted on a horizontal plate located at the top of the support legs. The adjustment mechanism adjusts the tilt angle of the triangular frames. Multiple support legs are arranged in a straight line, and multiple sets of triangular frames are arranged in parallel above the support legs. Connecting plates are provided at both ends of the gap formed by two adjacent triangular frames. Photovoltaic modules are laid on the plane formed by the triangular frames and connecting plates.

[0008] As one embodiment of this utility model, the support leg is configured as a T-shaped structure, and the bottom of the support leg is embedded in a concrete pile; the support leg, the triangular frame and the connecting plate are all made of I-beams, and the edges of two adjacent photovoltaic modules are supported on the same triangular frame and the connecting plate.

[0009] As one embodiment of this utility model, the adjustment mechanism includes a sleeve plate, an outer ring plate and a first motor. The outer ring plate is sleeved on the sleeve plate through a bearing connection. A gear ring is provided on the edge of the outer side wall of the outer ring plate. A gear is meshed on the side of the gear ring. The gear is sleeved on the power output shaft of the first motor.

[0012] As one embodiment of this utility model, it also includes a braking mechanism, which includes a threaded rod, a moving block, and a second motor. The threaded rod is connected to one side of the horizontal plate via a bearing, and the second motor is connected to the other side of the horizontal plate via a second support plate. The second motor and the threaded rod are connected via a sprocket and chain. The moving block is fitted to the horizontal plate, and the end of the threaded rod is threaded into the moving block.

[0013] As one embodiment of this utility model, the structure of the movable block is adapted to the structure of the space formed by the horizontal plate and the sleeve plate, and one end of the movable block extends into the sleeve plate, while the other end of the movable block is connected to the outer ring plate.

[0014] As one embodiment of this utility model, a side plate is fixedly provided at one end of the movable block protruding from the sleeve plate, and a pin is fixedly provided at the end of the side plate.

[0033] Example 1

[0034] like Figure 1 , Figure 2 As shown, to enhance the wind resistance of photovoltaic modules, this embodiment provides a new structure for supporting the photovoltaic modules. This structure includes support legs 2, triangular frames 3, and connecting plates 31. The number of support legs 2 and triangular frames 3 is equal, and the bottom of the support legs 2 is embedded in concrete piles, while the triangular frames 3 are installed on top of the support legs 2. Therefore, the support legs 2 stably support the triangular frames 3 in a vertical plane. Connecting plates 31 are provided at both ends of the gap formed by two adjacent triangular frames 3, and the upper surfaces of the connecting plates 31 and the triangular frames 3 are on the same plane. Therefore, photovoltaic modules 1 can be laid on top of the triangular frames 3 and the connecting plates 31.

[0035] like Figure 1 , Figure 2 As shown, to enhance the wind resistance of the structure, the outrigger 2, triangular frame 3, and connecting plate 31 are all made of I-beams, utilizing the high strength of the I-beams to improve the structure's wind resistance. Furthermore, the outrigger 2 is designed as a T-shaped structure, with its right-angled bottom inserted into a concrete pile, further enhancing the outrigger 2 and triangular frame 3's ability to resist upward forces.

[0036] like Figure 1 , Figure 2As shown, due to the large cross-section of the I-beam, when laying the photovoltaic module 1, the edges of two adjacent photovoltaic modules 1 are supported on the same triangular frame 3 and connecting plate 31, and the frame of the photovoltaic module 1 and the I-beam are connected by multiple bolts, forcing the photovoltaic module 1 to be stably installed on the structure.

[0037] like Figure 3 , Figure 4 , Figure 5 As shown, in order to reduce the contact area between the photovoltaic module 1 and the wind, the triangular frame 3 can be adjusted and installed on the top of the support leg 2. Specifically, an annular frame 33 is provided at the bottom of the triangular frame 3, and a horizontal plate 21 is vertically installed at the top of the support leg 2. The horizontal plate 21 is designed as an I-beam structure. The annular frame 33 is connected to the horizontal plate 21 through an adjustment mechanism 4. The adjustment mechanism 4 can control the annular frame 33 to drive the triangular frame 3 to rotate around the central axis, thereby adjusting the tilt angle of the upper side of the triangular frame 3. This facilitates the adjustment of the tilt angle of the photovoltaic module 1 in strong winds, reducing its direct contact area with the wind and reducing the impact force of strong winds.

[0038] like Figure 7 As shown, in order to adjust the tilt angle of the photovoltaic module 1, the adjustment mechanism 4 includes a sleeve plate 41, an outer ring plate 42, and a first motor 45. The inner structure of the sleeve plate 41 is adapted to the horizontal plate 21, and the sleeve plate 41 is fixedly sleeved on the horizontal plate 21. The outer ring plate 42 is sleeved on the outer side of the sleeve plate 41 via a bearing connection. A gear ring 44 is provided on the edge of the outer wall of the outer ring plate 42, and a gear is meshed on the side of the gear ring 44. The gear is sleeved on the power output shaft of the first motor 45. The first motor 45 is mounted on a first support plate 46, and the first support plate 46 is mounted on the end of the horizontal plate 21. Therefore, when the first motor 45 is working, the gear ring 44 can be controlled to drive the outer ring plate 42 to rotate. Since the outer ring plate 42 is fixedly connected to the annular frame 33, when the outer ring plate 42 rotates, the annular frame 33 drives the triangular frame 3 to rotate around the central axis, thereby realizing the adjustment of the tilt angle of the photovoltaic module 1.

[0039] like Figure 4 , Figure 7 As shown, to ensure a stable connection between the annular frame 33 and the outer ring plate 42, multiple studs 32 are fixedly installed on the side of the annular frame 33, and the outer ring plate 42 extends through the annular frame 33. Multiple ear plates 43 are also fixedly installed on the protruding edge of the outer ring plate 42 from the annular frame 33. The number of ear plates 43 is equal to the number of studs 32, and the ear plates 43 are fitted onto the studs 32. Nuts are threaded onto the ends of the studs 32, thus ensuring a stable connection between the outer ring plate 42 and the annular frame 33 through the cooperation of the nuts and studs 32.

[0040] like Figure 5 , Figure 6As shown, in order to ensure that the photovoltaic module 1 with adjustable tilt angle is placed stably, a braking mechanism 5 is also required on the top of the support leg 1. The braking mechanism 5 can release the restriction of the photovoltaic module 1 before adjusting the tilt angle of the photovoltaic module 1, and control the photovoltaic module 1 to be installed stably after adjusting the tilt angle of the photovoltaic module 1.

[0041] like Figure 6 As shown, specifically, the braking mechanism 5 includes a threaded rod 51, a moving block 52, and a second motor 56. The threaded rod 51 is connected to one side of the horizontal plate 21 via a bearing, and the second motor 56 is connected to the other side of the horizontal plate 21 via a second support plate 55. The second motor 56 is connected to the threaded rod 51 via a sprocket and chain, so the threaded rod 51 can be rotated under the action of the second motor 56. The structure of the moving block 52 is adapted to the structure of the space formed by the horizontal plate 21 and the sleeve plate 41, and one end of the moving block 52 extends into the sleeve plate 41. At the same time, the end of the threaded rod 51 is threaded into the moving block 52. When the threaded rod 51 rotates, the moving block 52 can be controlled to move along the length direction of the horizontal plate 21. Since the moving block 52 is adapted to the structure of the sleeve plate 41 and the horizontal plate 21, it only moves in a straight line, which provides convenience for controlling the photovoltaic module 1 at a certain tilt angle or adjusting the tilt angle of the photovoltaic module 1.

[0042] like Figure 6 , Figure 7 As shown, in order to restrict the photovoltaic module 1 by moving the movable block 52, a side plate 53 is fixedly provided at one end of the movable block 52 protruding from the sleeve plate 41, and a post 54 is fixedly provided at the end of the side plate 53. Multiple slots are evenly distributed along the circumference of the side wall of the outer ring plate 42, and the post 54 is inserted into a slot. When the movable block 52 moves away from the sleeve plate 41, the post can disengage from the slot, releasing the restriction of the outer ring plate 42. Under the action of the first motor 45, the outer ring plate 42 can be rotated to adjust the angle of the photovoltaic module 1. When the movable block 52 approaches the sleeve plate 41, the post is inserted into the slot, which can control the outer ring plate 42 to remain stationary relative to the sleeve plate 41 and the horizontal plate 21, forcing the triangular frame 3 and the photovoltaic module 1 to be stably at a certain tilt angle.

[0043] like Figure 2 As shown, in order to reduce the cost of the structure, a transmission rod can be connected between two adjacent threaded rods 51 located on the same straight line through a coupling, so that multiple threaded rods 51 can be controlled to rotate under the action of a second motor 56.

[0044] To facilitate control of the motor operation and adjustment of the tilt angle of photovoltaic module 1 by the control center, the motor needs to be equipped with a motor controller with remote control capabilities. Common types include programmable logic controllers (PLCs) and motion controllers. These controllers typically have multiple communication interfaces, such as RS-232, RS-485, Ethernet, and CAN bus. The appropriate communication module is selected based on the controller's communication interface type and the network environment of the remote control center. For example, if the remote control center controls the motor via the internet, a communication module with an Ethernet interface or Wi-Fi functionality can be selected; in a local area network in an industrial setting, a CAN bus or RS-485 communication module may be more suitable. Connecting the communication module to the motor controller enables communication between the controller and the external network. The first and second motors mentioned above can be configured as stepper motors, servo motors, etc.

[0045] Example 2

[0046] like Figure 8 , Figure 9 As shown in Example 1, to reduce the gas velocity difference between the upper and lower sides of the photovoltaic module 1, a protective plate 6 can be provided at the bottom of the space formed by the triangular frame 3 and the connecting plate 31. The protective plate 6 is arranged parallel to the lower side of the photovoltaic module 1, and both ends of the protective plate 6 are connected to the connecting plate 31 through end plates 62. If the protective plate 6 is set as a flat plate structure, the side away from the photovoltaic module 1 is flat, which reduces the pressure difference generated by the gas on the upper and lower sides of the photovoltaic module 1, and prevents the photovoltaic module 1 from detaching due to the upward force.

[0047] like Figure 9 As shown, of course, the side of the protective plate 6 away from the photovoltaic module 1 can also be set as a raised arc surface 61 according to the needs. This setting reduces the impact of buoyancy on the support leg 2, triangular frame 3, etc.

[0048] Furthermore, the technical solutions of the various embodiments of this utility model can be combined with each other, but only if they are based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.

[0049] The above-described embodiments are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the appended claims.
