Description

Technical Field

[0001] This utility model relates to photovoltaic cell module technology, specifically to a windproof fixing structure for photovoltaic cell modules. Background Technology

[0002] With the global energy structure shifting towards cleaner and renewable energy, the photovoltaic industry, as a core sector of the new energy field, is expanding its application scenarios from traditional centralized photovoltaic power plants to diverse scenarios such as distributed rooftop photovoltaics, building-integrated photovoltaics (BIPV), and photovoltaic power plants in deserts and plateaus. As the core unit for photoelectric conversion in photovoltaic systems, the stability of photovoltaic modules after outdoor installation directly determines the operating efficiency and lifespan of the entire photovoltaic system.

[0003] When existing windproof fixing structures for photovoltaic (PV) modules are in use, the frequent strong winds and gusts in outdoor environments become a key factor threatening the safe operation of PV modules. If the stability of the fixing structure is insufficient, strong wind loads can easily cause PV modules to shift, tilt, or even fall off. This can not only cause physical damage to the PV modules themselves, but may also lead to safety accidents such as short circuits in the PV array and power generation interruptions, resulting in serious economic losses to PV projects. Utility Model Content

[0004] The purpose of this invention is to provide a windproof fixing structure for photovoltaic cell modules, so as to solve the problem of poor windproof performance of photovoltaic cell modules in the prior art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a windproof fixing structure for a photovoltaic cell module, comprising a photovoltaic cell module body, wherein a fixing mechanism is provided on the outside of the photovoltaic cell module body for positioning the photovoltaic cell module body;

[0006] The bottom of the fixing mechanism is provided with an adjustable mechanism for adjusting the photovoltaic cell module body;

[0007] The fixing mechanism includes a U-shaped frame, eight first shafts and four second shafts. The U-shaped frame is located at the bottom of the photovoltaic cell module body. The first shafts and second shafts are rotatably connected to the top of the U-shaped frame through bearings. A gear is fitted on the outer ring of each of the first shafts. A connecting block is fitted on the outer ring of each of the first shafts and second shafts. A connecting rod is rotatably connected to the top of every two connecting blocks through bearings. A positioning plate is fitted on the outer ring of every two connecting rods.

[0008] The fixed mechanism is externally equipped with a drive mechanism for operating the fixed mechanism.

[0009] Furthermore, the drive mechanism includes a drive component one fixedly connected to both sides of the U-shaped frame. The output end of the drive component one is fitted with a reciprocating lead screw through a coupling. The outer ring of the reciprocating lead screw is fitted with a slide table. The middle of the slide table is provided with a circular hole. The bottom of the slide table is provided with a sliding groove. The two sides of the slide table are fixedly connected with racks.

[0010] Furthermore, each of the racks is meshed with a gear, and none of the gears are in contact with the connecting block.

[0011] Furthermore, the contact surfaces between the positioning plate and the photovoltaic cell module body are both made of rubber.

[0012] Furthermore, the adjustable mechanism includes a semi-ring seat fixedly connected to the bottom of the U-shaped frame. A crossbar is provided through the middle of the semi-ring seat. A half gear is fitted on the outer ring of the crossbar. Fixed seats are rotatably connected to both sides of the crossbar through bearings. A second driving component is provided on the left side of one of the fixed seats. A second gear is fixedly connected to the output shaft of the second driving component. The second gear and the half gear are meshed together.

[0013] Furthermore, the bottom of the two fixed seats is fixedly connected to a crossbeam, and the front of the crossbeam is provided with four threaded holes, and the inner cavity of each threaded hole is threadedly connected to a fixing bolt.

[0014] Compared with existing technologies, this utility model provides a windproof fixing structure for photovoltaic cell modules. The fixing mechanism and the driving mechanism are closely integrated. The driving component one drives the reciprocating screw, slide, and rack to rotate, which in turn drives the gear one to rotate synchronously with the first shaft. This, in turn, drives the positioning plate through the connecting block and connecting rod to stably clamp the photovoltaic cell module body. At the same time, the contact surface between the positioning plate and the module is made of rubber, which can ensure the windproof clamping effect while avoiding damage to the module surface due to compression or friction. This improves the wind resistance stability of the module after installation and effectively protects the integrity of the photovoltaic cell module body, extending its service life. The adjustable mechanism allows the structure to be flexibly adjusted. The driving component two drives the gear two to mesh with the half gear, which can drive the semi-ring seat, U-shaped frame, and photovoltaic cell module body to rotate around the crossbar, easily adjusting the tilt angle of the module to adapt to different time periods and different regional light conditions, thereby improving photovoltaic conversion efficiency. In addition, the cooperation between the crossbeam and the fixing bolts can firmly install the entire structure on the foundation carrier, further enhancing the overall wind resistance and installation stability of the structure, taking into account both practicality and functionality.

[0026] As attached Figure 1 To be continued Figure 4 As shown:

[0027] Example 1:

[0028] This utility model provides a windproof fixing structure for a photovoltaic cell module, including a photovoltaic cell module body 1, and a fixing mechanism is provided on the outside of the photovoltaic cell module body 1 for positioning the photovoltaic cell module body 1.

[0029] An adjustable mechanism is provided at the bottom of the fixing mechanism for adjusting the photovoltaic cell module body 1;

[0030] The fixing mechanism includes a U-shaped frame 201, eight first shafts 202 and four second shafts 203. The U-shaped frame 201 is set at the bottom of the photovoltaic cell module body 1. The first shafts 202 and the second shafts 203 are rotatably connected to the top of the U-shaped frame 201 through bearings. The outer ring of each first shaft 202 is fitted with a gear 204. The outer ring of each first shaft 202 and the second shaft 203 is fitted with a connecting block 205. The top of every two connecting blocks 205 is rotatably connected to a connecting rod 206 through a bearing. The outer ring of every two connecting rods 206 is fitted with a positioning plate 207.

[0031] The fixed mechanism is externally equipped with a drive mechanism for operating the fixed mechanism.

[0032] The drive mechanism includes drive components 301 fixedly connected to both sides of the U-shaped frame 201. The output end of each drive component 301 is fitted with a reciprocating screw 302 via a coupling. Each reciprocating screw 302 has a slide table 303 fitted on its outer ring. Each slide table 303 has a circular hole 304 through its center. Each slide table 303 has a groove 305 at its bottom. Each slide table 303 has a rack 306 fixedly connected to both sides. Each rack 306 meshes with a gear 204. Each gear 204 does not contact the connecting block 205. The contact surfaces between the positioning plate 207 and the photovoltaic cell module body 1 are made of rubber.

[0033] Working principle: When fixed, the drive component 301 set for the motor is started. Its output end drives the reciprocating screw 302 to rotate through the coupling, causing the slide 303 to move along the screw axis. The racks 306 on both sides of the slide 303 move synchronously, driving the meshing gear 204 to rotate, which in turn drives the first shaft 202 to rotate. The connecting block 205 on the first shaft 202 and the second shaft 203 rotates with the shaft. Through the connecting rod 206, it pushes the positioning plate 207 to move closer to the photovoltaic cell module body 1 until the positioning plate 207 is tightly attached to the surface of the photovoltaic cell module body 1, completing the clamping and fixing, and achieving the windproof effect.

[0034] During maintenance, the drive component 301 rotates in reverse, causing the reciprocating screw 302 to rotate in reverse, the slide 303 and rack 306 to move in opposite directions, the gear 204 and the first shaft 202 to rotate in opposite directions, and the connecting block 205 pulls the positioning plate 207 away from the photovoltaic module body 1 through the connecting rod 206, releasing the clamping state, so that the photovoltaic module body 1 can be maintained or replaced.

[0035] Example 2:

[0036] This embodiment is basically the same as the previous embodiment, except that the adjustable mechanism includes a semi-ring seat 401 fixedly connected to the bottom of the U-shaped frame 201. A crossbar 402 is provided through the middle of the semi-ring seat 401. A half gear 403 is fitted on the outer ring of the crossbar 402. Fixed seats 404 are rotatably connected to both sides of the crossbar 402 through bearings. A second driving component 405 is provided on the left side of one of the fixed seats 404. A second gear 406 is fixedly connected to the output shaft of the second driving component 405. The second gear 406 and the half gear 403 are meshed. A crossbeam 407 is fixedly connected to the bottom of the two fixed seats 404. Four threaded holes 408 are provided through the front of the crossbeam 407. A fixing bolt 409 is threadedly connected to the inner cavity of each threaded hole 408.

[0037] Working principle: First, the crossbeam 407 is attached to the installation foundation, such as a bracket, ground embedded part, or wall, so that the threaded hole 408 is aligned with the hole position of the installation foundation. The fixing bolt 409 is screwed into the threaded hole 408 and locked, completing the installation and fixing of the entire windproof fixing structure. When adjusting the angle, the second drive component 405, which is set for the motor, is started. Its output shaft drives the second gear 406 to rotate. The second gear 406 drives the meshing half gear 403 to rotate, which in turn drives the crossbar 402 and the semi-ring seat 401 to rotate around the axis of the crossbar 402. The U-shaped frame 201 on the top of the semi-ring seat 401 rotates synchronously with the photovoltaic cell module body 1 until the target suitable angle is adjusted. The angle of the photovoltaic cell module body 1 is kept stable, thereby preventing the photovoltaic cell module body 1 from not absorbing sunlight. At the same time, the clamping and angle adjustment of the photovoltaic cell module body 1 by the fixing mechanism and the adjustable mechanism also ensure the stability of the windproof.

[0038] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
