Description

Technical Field

[0001] The invention belongs to the technical field of solar photovoltaic power generation, and in particular relates to an adjustable support frame for solar photovoltaic power generation construction. Background Art

[0002] With the rapid development of solar photovoltaic power generation technology, the installation and maintenance of photovoltaic panels have put forward higher requirements on the stability, protection and adaptability of the support frame. In the existing technology, the solar photovoltaic support frame has the following shortcomings:

[0003] 1. Insufficient protection: Outdoor photovoltaic panels are exposed to the elements for long periods of time and are susceptible to erosion by wind, rain, dust, hail, etc. Surface scratches or damage will directly affect power generation efficiency. Traditional support frames lack targeted protective structures and rely solely on the strength of the photovoltaic panels themselves, resulting in a limited service life.

[0004] 2. Lack of emergency protection mechanism: When support components (such as connecting rods and sleeves) break due to long-term use or sudden external force, traditional support frames cannot achieve automatic correction or temporary fixation, and photovoltaic panels are prone to tipping over and damage, increasing maintenance costs and safety hazards. Summary of the Invention

[0005] In view of the above situation, in order to overcome the defects of the prior art, the present invention provides an adjustable support frame for solar photovoltaic power generation construction, which effectively solves the problems currently on the market.

[0006] The technical solution adopted by the present invention is as follows: The present invention proposes an adjustable support frame for solar photovoltaic power generation construction, including a mounting base structure for carrying components, and the mounting base structure is also used to connect a preset mounting base; a photovoltaic panel connection assembly, including a photovoltaic panel assembly and a mounting connection assembly, for generating electricity through photovoltaic panels; a buffer spring damping, provided on the mounting base structure, for connecting the photovoltaic panel connection assembly and the correction and protection mechanism; the correction and protection mechanism, provided on the mounting base structure, for supporting and protecting the photovoltaic panel connection assembly in emergency situations.

[0007] Furthermore, the photovoltaic panel assembly includes a photovoltaic panel and a sliding frame. The sliding frame is mounted on the photovoltaic panel and connected with the sliding frame by bolts. Transparent glass is embedded in the sliding frame.

[0008] Furthermore, the sliding frame and the photovoltaic panel may be detachably connected, or the sliding frame and the photovoltaic panel may be slidingly connected, or the sliding frame and the photovoltaic panel may be rotatably connected.

[0009] Furthermore, the mounting connection assembly includes a bearing assembly and a buffer assembly, and the bearing assembly and the buffer assembly are connected via a through shaft.

[0010] Furthermore, the corrective protection mechanism includes a rotary clamping assembly, a spiral spring and a limit assembly. The rotary clamping assembly is arranged on the mounting base structure, and the rotary clamping assembly is connected to the spiral spring for clamping the photovoltaic panel in an emergency situation. The limit assembly is installed on the mounting base structure to limit the rotary clamping assembly after the rotary clamping assembly is triggered.

[0011] Furthermore, one end of the buffer spring damper is fixedly connected to the photovoltaic panel connection assembly, and the other end of the buffer spring damper is fixedly connected to the correction and protection mechanism.

[0012] The beneficial effects achieved by the present invention using the above structure are as follows:

[0013] (1) The combined design of the sliding frame and transparent glass can not only prevent direct damage to the surface of the photovoltaic panel from the harsh outdoor environment, but also prevent light from being blocked, thus ensuring the normal power generation of the photovoltaic panel; the sliding frame's various connection methods (detachable, sliding, rotating) are adapted to different usage scenarios and are easy to install, clean and maintain;

[0014] (2) The correction protection mechanism is linked with the limit assembly through the volute spring. When a fault such as a connecting rod breakage occurs, it can automatically drive the clamping correction plate to fix the lifting sleeve and lock the position through the lifting limit rod to prevent the photovoltaic panel from tipping over and being damaged. At the same time, it can temporarily correct the angle to maintain the basic power generation function and reduce the loss caused by sudden faults.

[0015] (3) During the installation of the connection assembly, multiple groups of connecting rods and lifting sleeves form a stable support system. Combined with the buffering effect of the reset spring damping, it can effectively absorb the vibration energy generated by external forces such as strong winds, reduce the fatigue loss of photovoltaic panels and connecting components, and enhance the overall structure's wind and earthquake resistance in complex environments.

They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they should not be understood as limiting the present invention.

[0028] See also Figure 1-8 .

[0029] In some embodiments, the photovoltaic panel 202 can be a silicon-based photovoltaic panel (such as a monocrystalline silicon photovoltaic panel, a polycrystalline silicon photovoltaic panel), a thin-film photovoltaic panel (such as a copper indium gallium selenide photovoltaic panel, a perovskite photovoltaic panel), an organic photovoltaic panel, etc., and a monocrystalline silicon photovoltaic panel is described as an embodiment of the present invention.

[0030] Figure 1 Only some components of the photovoltaic panel 202 are shown schematically, and the actual shape, size, position and configuration of these components are not affected by the present invention. Figure 1 The photovoltaic panel 202 can also be compared with the Figure 1 May contain more or fewer parts.

[0031] In this embodiment, the photovoltaic panel assembly includes a photovoltaic panel 202 and a sliding frame 203 . The sliding frame 203 is mounted on the photovoltaic panel 202 and connected by bolts. Transparent glass 204 is embedded in the sliding frame 203 .

[0032] The sliding frame 203 is installed on the photovoltaic panel 202 to protect the photovoltaic panel 202 in an outdoor environment, effectively avoiding damage to the surface of the photovoltaic panel 202 in a relatively harsh outdoor environment, thereby avoiding affecting the normal use of the photovoltaic panel 202. The transparent glass 204 installed on the sliding frame 203 is used in conjunction with the sliding frame 203 to further protect the photovoltaic panel 202 and avoid blocking light, so that the photovoltaic panel 202 can be used normally.

[0033] The sliding frame 203 and the photovoltaic panel 202 may be detachably connected, or may be slidingly connected, or may be rotatably connected.

[0034] Among them, the sliding frame 203 and the photovoltaic panel 202 can be detachably connected, which means that the sliding frame 203 can be connected to the photovoltaic panel 202 by bolts and other common installation parts on the market, as long as the sliding frame 203 does not affect the photovoltaic panel 202 from receiving light.

[0035] Among them, the sliding frame 203 and the photovoltaic panel 202 can be slidably connected, which means that there is a sliding connection structure between the sliding frame 203 and the photovoltaic panel 202. The sliding connection structure can be a direct connection of a slide groove, or a structure such as a slide rail, pulley or ball.

[0036] The sliding frame 203 and the photovoltaic panel 202 may be connected in a rotational manner, which means that the sliding frame 203 is connected to the photovoltaic panel 202 at one point, and the connection is a rotational connection.

[0037] In some embodiments, the photovoltaic panel connection assembly further includes a mounting connection assembly, which includes a bearing assembly and a buffer assembly, and the bearing assembly and the buffer assembly are connected via a through-shaft 209.

[0038] In this embodiment, the bearing assembly includes a lifting sleeve 201, which is slidably connected to the mounting base structure 1; a connecting rod 205, which is evenly distributed on the lifting sleeve 201, and one end of the connecting rod 205 is rotatably connected to the lifting sleeve 201, for supporting the lifting sleeve 201 and the photovoltaic panel assembly; a fixed vertical plate 206, which is fixedly connected to the connecting rod 205; a limiting clamp 207, which is detachably connected to the fixed vertical plate 206 by bolts; a buffer assembly includes a sliding platform 208, which is arranged at one end of the connecting rod 205 away from the lifting sleeve 201; a through shaft 209, which penetrates and is rotatably connected to the connecting rod 205, for docking the bearing assembly and the buffer assembly.

[0039] The sliding platform 208 is slidably connected to the mounting base structure 1, and the buffer assembly also includes a return spring damper 210, which is arranged between the sliding platform 208 and the mounting base structure 1. One end of the return spring damper 210 is fixedly connected to the sliding platform 208, and the other end of the return spring damper 210 is fixedly connected to the mounting base structure 1.

[0040] Specifically, the lifting sleeve 201 is put on the mounting base structure 1, and then the connecting rod 205 is manually rotated so that the end of the connecting rod 205 away from the lifting sleeve 201 is rotated onto the sliding platform 208, and the through shaft 209 is used to pass through the sliding platform 208 and the connecting rod 205, so that the connecting rod 205 and the sliding platform 208 are connected as a whole. When the lifting sleeve 201 tilts, the return spring damper 210 can be squeezed by the sliding platform 208, so that the return spring damper 210 absorbs the energy generated when the lifting sleeve 201 shakes, thereby keeping the lifting sleeve 201 stable in windy weather outdoors.

[0041] It is understandable that there are four groups of connecting rods 205, which can reduce the shaking of the lifting sleeve 201 from all directions in a strong wind environment, which is beneficial to reducing the risk of damage to the photovoltaic panel 202 in harsh environments.

[0042] In some embodiments, the correction and protection mechanism 4 includes a rotary clamping assembly, a spiral spring 402 and a limiting assembly. The rotary clamping assembly is arranged on 1, and the rotary clamping assembly is connected to the spiral spring 402, and is used to clamp the photovoltaic panel 202 in an emergency situation. The limiting assembly is installed on 1 to limit the rotary clamping assembly after the rotary clamping assembly is triggered.

[0043] In this embodiment, the rotary clamping assembly includes a rotating disk 401, which is rotatably connected to the upper surface of the mounting base structure 1; a spiral spring 402, which is arranged between the rotating disk 401 and the mounting base structure 1, and is used to drive the rotating disk 401 to reset; a limiting slide groove 403, which is opened through the rotating disk 401, and is used to provide a limit for the sliding of the clamping correction plate 404; a fixed bracket 405, which is fixedly connected to the upper surface of the rotating disk 401; the limiting assembly includes columns 406, which are evenly distributed on the mounting base structure 1, and the columns 406 are fixedly connected to the mounting base structure 1; a lifting limit rod 407, which is slidably connected to the columns 406; a telescopic spring 408, which is arranged between the columns 406 and the lifting limit rod 407, one end of which is fixedly connected to the column 406, and the other end of which is fixedly connected to the lifting limit rod 407.

[0044] The lifting limit rod 407 abuts against the outer surface of the clamping and correcting plate 404 to limit the position movement of the clamping and correcting plate 404; the limiting clamping plate 207 is arranged between the fixed brackets 405, and the outer surface of the limiting clamping plate 207 abuts against the inner surface of the fixed bracket 405.

[0045] Among them, when the connecting rod 205 and the lifting sleeve 201 are damaged after long-term outdoor use, the connecting rod 205 will break. When the connecting rod 205 breaks, the connecting rod 205 will rotate around the through shaft 209. When the connecting rod 205 rotates, the limit card plate 207 connected to the connecting rod 205 will separate from the fixed bracket 405. After all the limit card plates 207 are separated from the fixed bracket 405, the rotating disk 401 rotates under the action of the spiral spring 402. As the spiral spring 402 rotates, the clamping Driven by the rotating disk 401, the correction plate 404 will slide along the limiting groove 403, so that the clamping correction plate 404 is close to the outer surface of the lifting sleeve 201. As the clamping correction plate 404 moves, the clamping correction plate 404 will gradually separate from the lifting limit rod 407. After the top of the lifting limit rod 407 is separated from the clamping correction plate 404, the lifting limit rod 407 moves upward under the action of the telescopic spring 408 until the side of the lifting limit rod 407 abuts against the outer surface of the clamping correction plate 404, so that the position of the clamping correction plate 404 is fixed.

[0046] It should be understood that the rotating disk 401, under the action of the spiral spring 402, provides auxiliary support to the lifting sleeve 201 when the connecting rod 205 breaks, which can prevent the photovoltaic panel 202 from tipping over and being damaged in extreme cases. At the same time, after the lifting limit rod 407 is attached to the outer surface of the lifting sleeve 201, the lifting limit rod 407 rises to limit the clamping correction plate 404, which can prevent the clamping correction plate 404 from displacing on its own. The clamping correction plate 404 can correct the angle of the lifting sleeve 201 under the joint action of the rotating disk 401 and the lifting limit rod 407, so that the lifting sleeve 201 can be used normally before maintenance.

[0047] In some embodiments, an installation base structure 1 is further included, and the installation base structure 1 includes a device base 101; a positioning column 102, fixedly installed in the middle position of the upper surface of the device base 101; a sliding groove 103, opened on the upper surface of the device base 101; an angle sensor 104, embedded in the device base 101, used to identify the rotation of the rotating disk 401 and send a signal; a protective cover 105, evenly distributed on the device base 101; and a rotation groove 106, opened in the center position of the device base 101.

[0048] In this embodiment, the sliding platform 208 is slidably connected to the sliding slot 103 , and the sliding platform 208 will not be separated from the sliding slot 103 due to the structure of the sliding slot 103 . The rotating disk 401 is rotatably connected to the rotating slot 106 .

[0049] When in use, the photovoltaic panel 202 is protected by the sliding frame 203. The sliding frame 203 can be matched with the photovoltaic panel 202 by a detachable connection (such as a bolt), a sliding connection (such as a slide groove, a slide rail, a pulley) or a rotating connection. The transparent glass 204 on the sliding frame 203 can not only avoid blocking the light, but also protect the surface of the photovoltaic panel 202 together with the sliding frame 203, reducing the damage to the photovoltaic panel 202 caused by the harsh outdoor environment (such as wind, rain, sand and dust). The installation connection assembly consists of a bearing assembly (lifting sleeve 201, connecting rod 205, fixed vertical plate 206, limit card plate 207) It is composed of a buffer component (sliding platform 208, through shaft 209, return spring damper 210), the lifting sleeve 201 is slidably connected to the mounting base, the connecting rod 205 is evenly distributed on the lifting sleeve 201 and connected to the sliding platform 208 through the through shaft 209, forming a support structure for the photovoltaic panel 202 assembly. When encountering external forces such as strong winds, the shaking of the lifting sleeve 201 is transmitted to the return spring damper 210 through the sliding platform 208. The spring damper absorbs energy to buffer vibration, and cooperates with multiple groups of connecting rods 205 (such as four groups) to reduce shaking in all directions and ensure structural stability.

[0050] The corrective protection mechanism 4 realizes protection in emergency situations through the rotating disk 401, the spiral spring 402, and the limiting assembly (column 406, lifting limiting rod 407, and telescopic spring 408). During normal operation, the connecting rod 205 abuts against the fixed bracket 405 on the rotating disk 401 through the limiting card plate 207 to limit the rotation of the rotating disk 401; when a fault such as the connecting rod 205 breaks occurs, the limiting card plate 207 disengages from the fixed bracket 405, and the rotating disk 401 rotates under the action of the spiral spring 402, driving the clamping correction plate 404 to slide along the limiting slot 403 and clamp the lifting sleeve 201. At the same time, the lifting limiting rod 407 is in contact with the telescopic spring 4 08, it rises and abuts against the clamping correction plate 404 to fix its position, thereby achieving angle correction and temporary support for the lifting sleeve 201 to prevent the photovoltaic panel 202 from tipping over. The installation base structure 1 (including the device base 101, positioning column 102, sliding groove 103, rotating groove 106, etc.) provides an installation basis for the overall structure. The sliding platform 208 slides along the sliding groove 103, and the rotating disk 401 rotates in the rotating groove 106. The angle sensor can identify the status of the rotating disk 401 and feedback signal to ensure that each component is linked in an orderly manner. The above is the overall workflow of the present invention. Just repeat this step when you use it next time. The actual operation process is very simple and easy.
