Description

Technical Field

[0001] This utility model relates to the field of photovoltaic module installation technology, specifically a photovoltaic module installation spacing adjuster. Background Technology

[0002] Currently, in the construction of photovoltaic power plants, the installation and fixing of photovoltaic modules generally adopts a combination of guide rails and independent clamping blocks. In actual construction, installers need to use measuring tools to determine the position of each installation point on the guide rail according to the design drawings, and manually adjust and fix each mounting bracket or clamping block base. This process is tedious and time-consuming, and is very prone to human error, resulting in uneven spacing and poor parallelism of the module array. This affects the aesthetics and structural safety of the system, and may also cause microcracks in the modules due to insufficient space for thermal expansion and contraction.

[0003] While some existing technologies offer adjustment devices designed to improve installation efficiency, such as the utility model patent "A Photovoltaic Module Spacing Adjuster" (authorization announcement number: CN222785925U) authorized by Zhejiang Ming'an Chaoju Intelligent Technology Co., Ltd., this patent provides a device comprising a locking component, a clamping component, and a spacing adjustment component. By placing the adjuster between adjacent photovoltaic modules and tightening it using screw holes, it aims to avoid accumulated errors and parallelism errors, and claims to be reusable. However, such devices typically still require individual adjustment and tightening of each module, making it difficult to achieve synchronous, equidistant adjustment between multiple mounting brackets. Operational efficiency still has room for improvement, and it is not convenient enough when adapting to different module specifications or quickly adjusting the spacing of an entire row. Similarly, regarding the fixing method of the modules themselves, most existing solutions still rely on tools to tighten the clamps, failing to achieve truly rapid installation. Utility Model Content

[0004] To address the shortcomings of existing technologies, this invention provides a photovoltaic module installation spacing adjuster, which solves the problems mentioned in the background section.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a photovoltaic module installation spacing adjuster, including a base and an installation frame, wherein the base is provided with multiple sets of equidistantly distributed installation frames, and the installation frames are provided with quick-connect mechanisms for quickly connecting the installation frames; Two sets of symmetrically distributed guide frames are slidably sleeved on the base. The two sets of mounting frames on the outer side are fixedly connected to the two sets of guide frames respectively. A mounting rod is fixedly installed on the base, and two sets of symmetrically distributed first adjusting rods are slidably installed on the mounting rod. A second adjusting rod is slidably installed inside each of the two sets of first adjusting rods. The ends of the two sets of second adjusting rods away from the mounting rod are fixedly connected to the corresponding guide frames respectively.

[0006] Preferably, photovoltaic modules are fixedly installed on the mounting frame, and multiple sets of mounting brackets on the inner side are slidably connected to the base or guide frame. Adjacent sets of mounting brackets are movably connected by two sets of first and second connecting rods that are cross-distributed and hinged to each other in the middle. The left ends of the two sets of first connecting rods are rotatably connected by a rotating shaft, and the left ends of the two sets of second connecting rods are rotatably connected by a rotating shaft. The right ends of the two sets of first connecting rods are rotatably mounted with sliders, and the sliders are slidably connected to the corresponding mounting brackets. The left ends of the two sets of second connecting rods are rotatably connected to the corresponding mounting brackets by rotating shafts.

[0007] Preferably, a bidirectional screw is rotatably installed inside the mounting rod, a first bevel gear is sleeved on the bidirectional screw, and a second bevel gear that meshes with the first bevel gear is rotatably installed inside the mounting rod. The second bevel gear is rotatably connected to the mounting rod via a first handle. A screw tube is rotatably installed inside each of the two sets of first adjusting rods. The two ends of the bidirectional screw pass through the two sets of first adjusting rods respectively and are threadedly connected to the two sets of first adjusting rods respectively. The two sets of screw tubes pass through the corresponding second adjusting rods respectively and are threadedly connected to the second adjusting rods.

[0008] Preferably, the bidirectional screw has two sets of symmetrically distributed keyways, and each set of screw tubes has two sets of symmetrically distributed key blocks. The key blocks are correspondingly arranged with the keyways, and both sets of screw tubes are slidably sleeved with the corresponding bidirectional screw through the key blocks and keyways.

[0009] Preferably, the quick-connect mechanism includes a plug fixedly installed on the mounting frame and limiting blocks symmetrically distributed on both sides of the plug. The mounting frame is movably engaged with the corresponding mounting bracket through the plug and the two sets of limiting blocks. Two sets of slides are slidably installed in the mounting bracket, and plug rods are fixedly installed on both sets of slides. The two sets of plug rods are movably engaged with the plug. Racks are fixedly installed on both sets of slides, and gears are provided between the two sets of racks. The gears mesh with the two sets of racks respectively. The gears are rotatably connected to the mounting bracket through the mounting shaft. A second handle is rotatably installed on the mounting bracket and distributed perpendicular to the mounting shaft. Slide rods corresponding to the slides are fixedly installed in the mounting bracket.

[0010] Preferably, a third bevel gear is sleeved on the mounting shaft, and a fourth bevel gear meshing with the third bevel gear is sleeved on the second handle. Both the mounting shaft and the second handle are sleeved with torsion springs, and the two ends of the torsion springs are fixedly connected to the corresponding third or fourth bevel gear and the mounting bracket, respectively. The two sets of slides are centrally symmetrical about the mounting shaft.

[0011] Preferably, the slide is slidably sleeved with the corresponding slide rod, and two sets of symmetrically distributed springs are sleeved on the slide rod, with the two ends of the two sets of springs respectively fixedly connected to the slide and the mounting bracket.

[0012] Compared with the prior art, the present invention provides a photovoltaic module installation spacing adjuster, which has the following beneficial effects: (1) By using a centralized first handle to drive the bidirectional screw and bevel gear set, the extension and retraction of all the first and second adjustment rods can be controlled synchronously, thereby driving the guide frames on both sides and all the mounting frames to move together, realizing the synchronous, equidistant, and stepless adjustment of the installation spacing of multiple photovoltaic modules. This greatly simplifies the adjustment process, avoids human error from measuring and positioning one by one, and ensures the uniformity of the spacing of the entire row of modules and the parallelism of the array. This not only improves the installation efficiency and aesthetics, but also fundamentally eliminates the risk of hidden cracks in the modules caused by improper space reservation for thermal expansion and contraction, significantly enhancing the structural safety and long-term reliability of the photovoltaic array.

[0013] (2) The quick-connect mechanism further enhances the installation experience and maintenance convenience. This mechanism utilizes a gear and rack transmission, and the opening and closing of the two plug rods can be controlled synchronously by rotating a single second handle. With the automatic reset force provided by the spring, it realizes the quick snap-fit ​​and separation between the mounting frame and the mounting bracket. The operation process does not require any tools, and the assembly and disassembly of the components can be completed with one hand, which greatly simplifies the installation and subsequent maintenance and replacement steps. While ensuring a firm and reliable connection, it truly achieves rapid installation, saving a lot of manpower and time costs for the construction and operation and maintenance of large-scale power plants.

[0016] The following will describe in detail the implementation of this application with reference to the accompanying drawings and embodiments, so that the implementation process of how this application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0017] Figures 1-6 In one embodiment of this utility model, a photovoltaic module 2 mounting spacing adjuster includes a base 3 and a mounting frame 1. The base 3 has multiple sets of equidistantly distributed mounting brackets 4, and each mounting bracket 4 has a quick-connect mechanism 6 for quickly connecting the mounting frame 1. Two sets of symmetrically distributed guide brackets 501 are slidably sleeved on the base 3. The two outer sets of mounting brackets 4 are respectively fixedly connected to the two sets of guide brackets 501. Mounting rods 502 are fixedly installed on the base 3, and two sets of symmetrically distributed first adjusting rods 503 are slidably installed on the mounting rods 502. Second adjusting rods 504 are slidably installed within each of the two sets of first adjusting rods 503. The ends of the two sets of second adjusting rods 504 away from the mounting rods 502 are respectively fixedly connected to the corresponding guide brackets 501. The spacing between the two outer sets of guide brackets 501 is adjusted by the synchronous sliding of the two sets of first adjusting rods 503 and the two sets of second adjusting rods 504 in opposite directions. The quick-connect mechanism 6 simplifies the installation steps of the mounting frame 1 on the mounting brackets 4, saving manpower and time costs, and improving the installation experience and maintenance convenience.

[0018] In this embodiment, reference Figure 2 , Figure 3 , Figure 4As shown, a photovoltaic module 2 is fixedly installed on the mounting frame 1. Multiple sets of mounting brackets 4 on the inner side are slidably connected to the base 3 or guide frame 501. Adjacent sets of mounting brackets 4 are movably connected by two sets of cross-distributed first connecting rods 512 and second connecting rods 513 that are hinged together at the middle. The left ends of the two sets of first connecting rods 512 are rotatably connected by a rotating shaft, and the right and left ends of the two sets of second connecting rods 513 are rotatably connected by a rotating shaft. A slider 514 is rotatably mounted on the right end of the two sets of first connecting rods 512, and the slider 514 is slidably connected to the corresponding mounting bracket 4. The left ends of the two sets of second connecting rods 513 are rotatably connected to the corresponding mounting bracket 4 by a rotating shaft. A bidirectional screw 505 is rotatably mounted inside the mounting rod 502, and a first bevel gear 506 is sleeved on the bidirectional screw 505. A second bevel gear 507, meshing with the first bevel gear 506, is rotatably mounted inside the mounting rod 502. The second bevel gear 507 is connected to the first bevel gear 506 via a first... Handle 508 is rotatably connected to mounting rod 502. Each of the two sets of first adjusting rods 503 has a rotatably mounted screw tube 510. The two ends of the bidirectional screw 505 pass through the two sets of first adjusting rods 503 and are threadedly connected to them. The two sets of screw tubes 510 pass through the corresponding second adjusting rods 504 and are threadedly connected to them. The bidirectional screw 505 has two symmetrically distributed keyways 509. Each of the two sets of screw tubes 510 has two symmetrically distributed key blocks 511. The key blocks 511 correspond to the keyways 509, and both sets of screw tubes 510 are slidably sleeved with the corresponding bidirectional screw 505 through the key blocks 511 and keyways 509. During operation, rotating the first handle 508 on the mounting rod 502 rotates the second bevel gear 507 at its end, thereby driving the meshing first bevel gear 506 and the bidirectional screw 505 to rotate synchronously. The threads on both sides of the bidirectional screw 505 rotate in opposite directions, allowing the two sets of first adjusting rods 503 fitted onto it to move towards or away from each other. The screw tube 510 inside the first adjusting rod 503 rotates synchronously with the bidirectional screw 505 through the cooperation of the keyway 509 and the key block 511, converting the rotational motion into linear motion, which pushes the second adjusting rod 504 to extend or retract, and finally transmits the driving force to the guide frames 501 on both sides. At the same time, through multiple sets of first connecting rods 512 and second connecting rods 513 with cross-hinged joints in the middle, the synchronous motion of the guide frames 501 on both sides is efficiently transmitted to all intermediate mounting frames 4, thereby realizing the equidistant and synchronous unfolding or retraction of the entire row of mounting frames 4, and completing the precise and efficient adjustment of the installation spacing of all photovoltaic modules 2 in one go.

[0019] In this embodiment, reference Figure 5 and Figure 6As shown, the quick-connect mechanism 6 includes a plug 601 fixedly installed on the mounting frame 1, and limiting blocks 602 symmetrically distributed on both sides of the plug 601. The mounting frame 1 is movably engaged with the corresponding mounting bracket 4 through the plug 601 and the two sets of limiting blocks 602. Two sets of slides 603 are slidably installed in the mounting bracket 4, and plug rods 604 are fixedly installed on each of the two sets of slides 603. The two sets of plug rods 604 are movably engaged with the plug 601 respectively. Racks 605 are fixedly installed on each of the two sets of slides 603, and gears 606 are provided between the two sets of racks 605. The gears 606 mesh with the two sets of racks 605 respectively. The gear 606 is rotatably connected to the mounting frame 4 via the mounting shaft 607. A second handle 613, perpendicular to the mounting shaft 607, is rotatably mounted on the mounting frame 4. A slide rod 611, corresponding to the slide 603, is fixedly mounted inside the mounting frame 4. A third bevel gear 608 is sleeved on the mounting shaft 607, and a fourth bevel gear 609, meshing with the third bevel gear 608, is sleeved on the second handle 613. Torsion springs 610 are sleeved on both the mounting shaft 607 and the second handle 613, with each end of the torsion spring 610 engaging with either the corresponding third bevel gear 608 or fourth bevel gear 609. Mounting bracket 4 is fixedly connected. Two sets of slides 603 are centrally symmetrically distributed about mounting axis 607. The slides 603 are slidably sleeved with the corresponding slide rods 611, and two sets of symmetrically distributed springs 612 are sleeved on the slide rods 611. The two ends of the two sets of springs 612 are fixedly connected to the slides 603 and mounting bracket 4 respectively. When fixing the assembly, simply align the insert 601 on mounting frame 1 and insert it into the slot of mounting bracket 4. During the pressing process, the insert 601 will squeeze the inclined surfaces of the insert rods 604 on both sides, forcing the slides 603 with racks 605 to slide outward along the slide rods 611, compressing the springs 612. Driven by rack 605, gear 606 rotates. When insert block 601 is fully in place, gear 606 rotates in the opposite direction under the combined rebound action of torsion spring 610 and spring 612, driving rack 605 and insert rod 604 to reset and automatically engage in the limiting hole of insert block 601, achieving a secure lock. For disassembly, simply rotate second handle 613 in the opposite direction, driving third bevel gear 608 and gear 606 to rotate via fourth bevel gear 609, which will cause racks 605 on both sides to drive insert rod 604 to disengage from insert block 601, thereby quickly releasing the lock. The entire assembly and disassembly process is labor-saving, quick, safe and reliable.

[0020] In this embodiment, during operation, the first handle 508 on the mounting rod 502 is rotated, which drives the second bevel gear 507 at its end to rotate, thereby driving the first bevel gear 506 and the bidirectional screw 505 that mesh with it to rotate synchronously. The threads on both sides of the bidirectional screw 505 rotate in opposite directions, allowing the two sets of first adjusting rods 503 fitted onto it to move towards or away from each other. The screw tube 510 inside the first adjusting rod 503 rotates synchronously with the bidirectional screw 505 through the cooperation of the keyway 509 and the key block 511, converting the rotational motion into linear motion, pushing the second adjusting rod 504 to extend or retract, and finally transmitting the driving force to the guide frames 501 on both sides. At the same time, through multiple sets of first connecting rods 512 and second connecting rods 513 with cross-hinged joints in the middle, the synchronous movement of the guide frames 501 on both sides is efficiently transmitted to all the intermediate mounting frames 4, thereby achieving equidistant and synchronous expansion or contraction of the entire row of mounting frames 4, completing the precise and efficient adjustment of the installation spacing of all photovoltaic modules 2 in one go. When fixing the modules, it is only necessary to insert the plug 60 on the mounting frame 1. Align and insert the insert 601 into the slot of the mounting bracket 4. During the pressing process, the insert block 601 will press the inclined surfaces of the insert rods 604 on both sides, forcing the slide 603 with rack 605 to slide outward along the slide rod 611 and compress the spring 612. The rack 605 drives the gear 606 to rotate. When the insert block 601 is fully in place, under the combined rebound action of the torsion spring 610 and the spring 612, the gear 606 rotates in the opposite direction, driving the rack 605 and the insert rods 604 to reset and automatically lock into the limiting hole of the insert block 601, achieving a firm lock. When disassembling, simply turn the second handle 613 in the opposite direction. The fourth bevel gear 609 drives the third bevel gear 608 and the gear 606 to rotate, which will cause the racks 605 on both sides to drive the insert rods 604 to disengage from the insert block 601, thereby quickly releasing the lock. The entire assembly and disassembly process is labor-saving, quick, safe and reliable.
