Description

Technical Field

[0001] This invention relates to the field of photovoltaic power plant construction equipment technology, specifically to an adjustable positioning fixture for photovoltaic module installation and its construction method. Background Technology

[0002] With the continuous construction of photovoltaic power generation projects, application scenarios such as rooftop distributed photovoltaics, ground-mounted centralized photovoltaics, and agricultural-photovoltaic complementary photovoltaics are increasing. Photovoltaic modules are typically installed on rooftops or support structures using photovoltaic rails, supporting components, and connectors. The module installation process involves steps such as rail positioning, module spacing control, module elevation adjustment, and clamping and fixing. The installation accuracy of the rails and modules affects the overall flatness of the photovoltaic array, the consistency of the module arrangement, and the structural stability during subsequent operation.

[0003] In the current photovoltaic module installation process, construction workers typically use methods such as laying out lines, measuring with tape measures, checking with a spirit level, and using temporary clamps for positioning. Existing clamps or positioning devices are mostly connected to the installation rails via bolt tightening, pressure plate clamping, or snap-fit ​​connections. This type of structure requires repeated measurement and adjustment during installation; when there are undulations in the roof substrate, deviations in the installation position of supporting components, or cumulative errors between multiple installation points, the installation position and angle of the installation rails are prone to deviation, thus affecting the installation accuracy of subsequent modules.

[0004] Furthermore, different models of mounting rails vary in cross-sectional dimensions, slot sizes, and connection positions, limiting the compatibility of conventional temporary installation tools. During module installation, improper adjustments to component support positions, installation heights, component spacing, or installation tilt angles can lead to uneven component arrangement, insufficient panel flatness, and uneven localized stress. Therefore, improving the ease of mounting rail positioning and component installation adjustments during photovoltaic module construction remains a problem that those skilled in the art need to address. Summary of the Invention

[0015] This invention also provides a construction method for an adjustable positioning fixture for photovoltaic module installation, comprising the following steps: S1. Set up the photovoltaic module installation baseline at the installation site, and pre-adjust the base unit and auxiliary tooling according to the photovoltaic module specifications; S2. Arrange multiple base units at intervals along the installation baseline and fix each base unit with an angle clamp. S3. Pass the photovoltaic guide rail through multiple ring frames in sequence, so that the main clamp slider and the main clamp rough block enter the inner track of the photovoltaic guide rail; S4.

[0016] Compared with the prior art, the beneficial effects of the present invention are: This invention provides an adjustable positioning fixture for photovoltaic module installation and its construction method. Through base units spaced apart along the length of the photovoltaic guide rail, a ring frame that rotates with the ring rail, and auxiliary fixtures mounted on the photovoltaic guide rail, the photovoltaic guide rail can be positioned and installed among multiple base units. By rotating the ring frame to adjust the installation orientation of the photovoltaic guide rail, and by clamping and fixing the photovoltaic guide rail with main clamping components and auxiliary clamping components, positional and angular deviations generated during installation can be adjusted, reducing the reliance on repeated manual measurement and calibration during guide rail installation and improving the positioning convenience of photovoltaic guide rail installation.

[0017] This invention utilizes guide rods on a ring rail and annular grooves on the outer circumference of the ring frame to mate with the guide rods, allowing the guide rods to extend into the grooves and axially limit the ring frame. After the photovoltaic guide rail's installation orientation is adjusted, the guide rods are tightened to restrict the ring frame's rotation relative to the ring rail, maintaining the adjusted installation posture of the photovoltaic guide rail. Simultaneously, a main clamping slider and a main clamping rough block are positioned within the inner track of the photovoltaic guide rail. The smooth surface of the main clamping slider facilitates the insertion of the photovoltaic guide rail, while the rough surface of the main clamping rough block increases the frictional force after clamping. An auxiliary clamping screw drives a contact plate to abut against the outer surface of the photovoltaic guide rail, causing the contact plate and the main clamping assembly to clamp the photovoltaic guide rail from both the inner and outer sides, reducing the possibility of the photovoltaic guide rail shifting or deflecting under stress.

[0018] This invention comprises a base unit consisting of a substrate, side plates, inserts, through slots, and springs. The substrate is attached to the upper surface of the photovoltaic guide rail, and the two side plates are attached to both sides of the photovoltaic guide rail. The inserts slide within the through slots and cooperate with the springs, allowing the side plates to move relative to the substrate. A fastening screw drives a fastener located within the inner track of the photovoltaic guide rail to rotate, causing the rough edges at both ends of the fastener to contact the inner track, forming a multi-position clamping mechanism with the substrate and side plates. The sealing cover engages with the inserts via detachable clips, restricting the position of the side plates. The clamping position of the side plates can be adjusted by replacing different sized clips, improving the installation stability of the auxiliary tooling and its adaptability to different specifications of photovoltaic guide rails.

[0019] This invention hinges the two ends of the telescopic sleeve to the base unit and the frame structure respectively, and sets a flexible pad on the surface of the frame. By adjusting the length of the telescopic sleeve and the tilt angle of the frame structure, the frame is positioned in a support position corresponding to the installation position of the photovoltaic module. When the flexible pad contacts the photovoltaic module, it forms a buffer, reducing the rigid contact between the frame and the photovoltaic module, and facilitating the adjustment of the installation height, installation tilt angle and support position of the photovoltaic module.

Detailed Implementation

[0032] The present invention will be further described in detail below through specific embodiments, but it should not be construed as limiting the scope of the subject matter of the present invention to the following embodiments. All technologies implemented based on the above content of the present invention fall within the scope of the present invention.

[0033] In one embodiment of the present invention, an adjustable positioning fixture for installing photovoltaic modules is provided, the structural schematic diagram of which is shown below. Figure 1 As shown, it includes: multiple base units 1, photovoltaic guide rails 2, and auxiliary fixtures. The multiple base units 1 are arranged at intervals along the length of the photovoltaic guide rails 2, and the photovoltaic guide rails 2 are sequentially inserted into each base unit 1; the auxiliary fixtures are detachably installed on the photovoltaic guide rails 2 and are located below or to the side below the photovoltaic modules to be installed, so as to support and adjust the installation position of the photovoltaic modules.

[0034] like Figure 2 , Figure 3 and Figure 4 As shown, the base unit 1 includes a base assembly and a guide rail clamping mechanism. The base assembly includes an angle clamp 101, a rail seat 102, and a ring rail 103. The angle clamp 101 is clamped and fixed to the load-bearing part of the installation site. The rail seat 102 is fixedly connected to the top of the angle clamp 101, and the ring rail 103 is fixedly connected to the top of the rail seat 102. The ring rail 103 is configured as an annular structure with an inner hole. The ring frame 106 in the guide rail clamping mechanism is coaxially arranged in the inner hole of the ring rail 103. The outer circumferential surface of the ring frame 106 is rotatably engaged with the inner circumferential surface of the ring rail 103. The photovoltaic guide rail 2 passes through the inner hole of the ring frame 106.

[0035] like Figure 5 As shown, a guide rod 104 is threadedly connected to the top of the ring rail 103, and a handle 105 is fixedly connected to the upper end of the guide rod 104. An annular groove 107 extending circumferentially is formed on the outer circumferential surface of the ring frame 106, and the lower end of the guide rod 104 extends into the annular groove 107. When the guide rod 104 is in the loosened state, the ring frame 106 can rotate relative to the ring rail 103; after tightening the handle 105, the guide rod 104 moves towards the bottom of the annular groove 107, forming a circumferential limit on the ring frame 106.

[0036] like Figure 6 As shown, a first base platform 108 is fixedly connected to the lower part of one side of the ring frame 106, and a second base platform 109 is fixedly connected to the upper part of the same side of the ring frame 106.

[0037] A main clamping assembly is provided on the first base platform 108. The main clamping assembly includes a main clamping screw 110, a main clamping slider 111, a main clamping rough block 112, a main clamping bolt 113, and a main clamping sleeve 114. The main clamping screw 110 passes through the first base platform 108. The main clamping slider 111 and the main clamping rough block 112 are connected to one end of the main clamping screw 110 facing the photovoltaic guide rail 2. The main clamping bolt 113 is threadedly connected to the other end of the main clamping screw 110.

[0038] like Figure 7 and Figure 8 As shown, both the main clamping slider 111 and the main clamping rough block 112 extend into the inner track of the photovoltaic guide rail 2. The main clamping slider 111 is positioned near the bottom of the inner track, while the main clamping rough block 112 is positioned near the opening of the inner track. The main clamping sleeve 114 is movably fitted onto the main clamping screw 110 and engages with the opening of the inner track of the photovoltaic guide rail 2. The surface of the main clamping slider 111 that contacts the photovoltaic guide rail 2 is a relatively smooth contact surface, while the surface of the main clamping rough block 112 that contacts the photovoltaic guide rail 2 is a rough contact surface. When the photovoltaic guide rail 2 is installed between multiple base units 1, the main clamping slider 111 engages with the inner track, facilitating the movement of the photovoltaic guide rail 2 along the installation direction. After the main clamping bolt 113 is tightened, the main clamping rough block 112 contacts the inner track and forms a friction lock. The main clamping slider 111 and the main clamping rough block 112 are located at different depths within the inner track, forming layered support and clamping, restricting the movement, rotation, and offset of the photovoltaic guide rail 2 along its length, thus improving the stability of the photovoltaic guide rail after installation.

[0039] An auxiliary clamping assembly is provided on the second base platform 109. The auxiliary clamping assembly includes an auxiliary clamping screw 115, a mounting plate 116, and a clamp 117. The auxiliary clamping screw 115 passes through the second base platform 109. The mounting plate 116 is fixedly connected to one end of the auxiliary clamping screw 115 facing the photovoltaic guide rail 2. The clamp 117 is sleeved on the other end of the auxiliary clamping screw 115 and mates with the outer surface of the second base platform 109. When the auxiliary clamping screw 115 is adjusted, the mounting plate 116 moves toward or away from the photovoltaic guide rail 2. After the mounting plate 116 abuts against the outer surface of the photovoltaic guide rail 2, the mounting plate 116, together with the main clamping slider 111 and the main clamping rough block 112 extending into the inner track, form a clamping effect on both the inner and outer sides of the photovoltaic guide rail 2.

[0040] The auxiliary tooling includes a base unit 3, a telescopic adjustment unit 4, and a frame structure 5. For example... Figure 9As shown, the base unit 3 includes a substrate 301, through slots 302, side plates 303, inserts 304, and springs 305. The substrate 301 is attached to the upper surface of the photovoltaic guide rail 2, and multiple through slots 302 are spaced apart on both sides of the substrate 301; two side plates 303 are respectively disposed on both sides below the substrate 301, and multiple inserts 304 are fixedly connected to the upper part of each side plate 303. The inserts 304 are slidably inserted into the corresponding through slots 302, and the springs 305 are connected between the inserts 304 and the substrate 301.

[0041] The substrate 301 is attached to the upper surface of the photovoltaic rail 2, and the two side plates 303 are attached to the two sides of the photovoltaic rail 2. The insert 304 moves within the through groove 302 and moves the side plates 303 closer to or further away from the photovoltaic rail 2, so that the base unit 3 can be matched with photovoltaic rails 2 of different cross-sectional sizes; the spring 305 maintains the connection between the insert 304 and the through groove 302 and provides an elastic force to the side plates 303.

[0042] like Figure 10 As shown, the base unit 3 also includes a fastening screw 306, a fastener, a fastening bolt 309, and a fastening sleeve 310. The fastening screw 306 passes through the base plate 301, the fastener is connected to one end of the fastening screw 306 facing the photovoltaic guide rail 2, the fastening bolt 309 is threaded to the other end of the fastening screw 306, and the fastening sleeve 310 is movably sleeved on the fastening screw 306 and cooperates with the inner track opening of the photovoltaic guide rail 2.

[0043] The fastener is inserted into the inner track of the photovoltaic guide rail 2. The fastener includes a central body 307 and rough bodies 308 connected to both ends of the body 307. The fastener has a parallelogram-shaped structure. During the rotation of the fastening bolt 309, the fastening screw 306 drives the fastener to rotate within the inner track of the photovoltaic guide rail 2, and the two rough bodies 308 contact the inner track. The base plate 301, side plate 303, and fastener respectively mate with different surfaces of the photovoltaic guide rail 2, keeping the auxiliary tooling in the set position on the photovoltaic guide rail 2. The fastener adopts a rotational engagement method, so it is not necessary to completely remove the fastening bolt 309 when unlocking, which facilitates the assembly and disassembly of the auxiliary tooling.

[0044] like Figure 11As shown, the base unit 3 also includes a sealing cover 311 and a removable locking block 312. The sealing cover 311 is fastened to the top of the base plate 301 and covers the area where the fastening screw 306 and fastening bolt 309 are located. The lower surface of the sealing cover 311 is provided with a plurality of removable locking blocks 312, each of which is inserted into a corresponding through slot 302 and engages with the insert strip 304 located in the through slot 302. After the locking block 312 is inserted into the through slot 302, it restricts the position of the insert strip 304 and the side plate 303. When the cross-sectional specifications of the photovoltaic rail 2 change, the corresponding locking block 312 can be replaced so that the side plate 303 maintains a clamping position that is compatible with the photovoltaic rail 2.

[0045] like Figure 12 As shown, the telescopic adjustment unit 4 includes a telescopic sleeve 401 and an adjusting bolt 402, with the adjusting bolt 402 threadedly connected to the side wall of the telescopic sleeve 401. One end of the telescopic sleeve 401 is hinged to the base plate 301 of the base unit 3, and the other end is hinged to the frame structure 5. The frame structure 5 includes a stepped frame block 501 and a flexible pad 502 laid on the surface of the frame block 501, which contacts the photovoltaic module. By adjusting the telescopic length of the telescopic sleeve 401 and the hinge angle at both ends, the height and tilt angle of the frame block 501 relative to the photovoltaic guide rail 2 can be changed; after the frame block 501 is adjusted to the set position, the adjusting bolt 402 is tightened to maintain the length of the telescopic sleeve 401.

[0046] After the photovoltaic module has been initially positioned and leveled, the telescopic adjustment unit 4 can deflect downwards, causing the frame block 501 to press against the module frame or supporting part from above the photovoltaic module; the flexible pad 502 is located between the frame block 501 and the photovoltaic module to reduce rigid contact. Through the length adjustment of the telescopic sleeve 401, the hinge angle adjustment, and the locking engagement of the adjusting bolt 402, the frame block 501 is kept in a supporting or pressing state on the photovoltaic module.

[0047] This invention also provides a construction method for an adjustable positioning fixture for photovoltaic module installation, comprising the following steps: S1. Set up the photovoltaic module installation baseline at the installation site, and pre-adjust the base unit 1 and auxiliary tooling according to the photovoltaic module specifications; S2. Arrange multiple base units 1 at intervals along the installation reference line, and fix each base unit 1 by the angle clamp 101. S3. Pass the photovoltaic guide rail 2 through multiple ring frames 106 in sequence, so that the main clamping slider 111 and the main clamping rough block 112 enter the inner track of the photovoltaic guide rail 2. S4. Rotate the ring frame 106 to adjust the installation orientation of the photovoltaic guide rail 2, tighten the guide rod 104, and clamp the photovoltaic guide rail 2 through the main clamp assembly and the auxiliary clamp assembly; S5. Clamp the base unit 3 onto the photovoltaic guide rail 2, insert the fastener into the inner track of the photovoltaic guide rail 2, rotate the fastening screw 306 and tighten the fastening bolt 309. S6. Adjust the length of the telescopic sleeve 401 and the tilt angle of the frame block 501, tighten the adjusting bolt 402, and place the photovoltaic module on the frame block 501 to complete the installation.

[0048] To further understand the technical solution of the present invention, a detailed description is provided in conjunction with specific embodiments: The specific steps for installing photovoltaic modules for a certain photovoltaic power station model are as follows: Based on the photovoltaic power station construction drawings, determine the installation layout, installation direction, module spacing, and guide rail arrangement positions of the photovoltaic modules; inspect the area to be installed, clean debris from the roof or supporting structure surface, and check the integrity of the angle clamp 101, rail base 102, ring rail 103, ring frame 106, main clamping components, auxiliary clamping components, and auxiliary tooling. Based on the photovoltaic module dimensions and the cross-sectional specifications of the photovoltaic guide rail 2, pre-select a clamping block 312 that matches the photovoltaic guide rail 2, and pre-adjust the initial length of the telescopic sleeve 401 and the initial angle of the frame block 501.

[0049] Mark the installation baseline for the first row of photovoltaic modules on the installation site, and determine the installation position of each base unit 1 according to the design spacing; for multiple parallel photovoltaic guide rails 2, mark the corresponding guide rail installation baseline to ensure that the installation position of each guide rail corresponds to the arrangement direction of the modules.

[0050] Angle clamp 101 is clamped onto the load-bearing part of the installation site, so that the rail base 102 and the ring rail 103 are oriented towards the preset photovoltaic guide rail installation direction; the position of each angle clamp 101 is adjusted so that multiple ring rails 103 corresponding to the same photovoltaic guide rail 2 are roughly in the same straight line, and then the angle clamp 101 is fixed. During installation, the ring frame 106 is positioned in the inner hole of the ring rail 103, and the guide rod 104 is screwed into the top of the ring rail 103, so that the lower end of the guide rod 104 extends into the annular groove 107 on the outer circumference of the ring frame 106; at this time, the guide rod 104 is kept in a state of not being fully tightened, so that the ring frame 106 can rotate relative to the ring rail 103.

[0051] One end of the photovoltaic guide rail 2 is sequentially passed through the inner holes of multiple ring frames 106, and the main clamping slider 111, main clamping rough block 112, and main clamping sleeve 114 are inserted into the inner track of the photovoltaic guide rail 2. During the insertion process, the smooth contact surface of the main clamping slider 111 engages with the inner track of the photovoltaic guide rail 2, and the photovoltaic guide rail 2 moves sequentially along multiple base units 1. After the photovoltaic guide rail 2 reaches the predetermined position, the spacing between adjacent base units 1 and the extension length of the photovoltaic guide rail 2 are adjusted so that the photovoltaic guide rail 2 corresponds to the installation reference line.

[0052] Based on the installation baseline, the position of adjacent photovoltaic rails 2, and the actual installation status of the roof or supporting structure, rotate the ring frame 106 in each base unit 1 to ensure that the installation orientation of the photovoltaic rails 2 meets the module installation requirements. After adjusting the orientation, rotate the handle 105 to move the guide rod 104 downward and engage with the ring groove 107, thus creating a circumferential limit on the ring frame 106. Then, tighten the main clamping bolt 113 to make the main clamping slider 111 and the main clamping block 112 abut against the inner track of the photovoltaic rails 2. Next, adjust the auxiliary clamping screw 115 to make the plate 116 press against the outer surface of the photovoltaic rails 2, and maintain the position of the auxiliary clamping screw 115 through the clamp 117. After locking each base unit 1 in sequence, check the straightness, installation height, and installation orientation of the photovoltaic rails 2. If the check does not meet the requirements, loosen the guide rod 104, main clamping bolt 113, or auxiliary clamping screw 115 in the corresponding position, readjust, and then tighten again.

[0053] Based on the installation position of the photovoltaic module, determine the installation points of the auxiliary tooling on the photovoltaic guide rail 2. Attach the substrate 301 to the upper surface of the photovoltaic guide rail 2, so that the two side plates 303 are located on both sides of the photovoltaic guide rail 2. Push or pull the side plates 303 to move the insert 304 within the through groove 302 until the side plates 303 are in contact with the side of the photovoltaic guide rail 2. Insert the fastener into the inner track of the photovoltaic guide rail 2, so that the fastening sleeve 310 is located at the opening of the inner track. Rotate the fastening bolt 309 to cause the fastening screw 306 to drive the fastener to rotate until the rough parts 308 at both ends of the fastener abut against the inner track of the photovoltaic guide rail 2. After the position of the base unit 3 is adjusted, fasten the sealing cover 311 above the substrate 301 and insert the locking block 312 into the corresponding through groove 302, so that the locking block 312 engages with the insert 304, thus restricting the position of the side plate 303.

[0054] Based on the installation height, tilt angle, and design spacing between adjacent photovoltaic modules, adjust the length of the telescopic sleeve 401, and adjust the support angle of the frame block 501 by adjusting the hinge position between the telescopic sleeve 401 and the substrate 301 and the frame block 501.
