Description

Technical Field

[0001] This invention relates to the field of photovoltaic installation, specifically to a flat, lightweight plastic photovoltaic installation support frame. Background Technology

[0002] Flat-lay photovoltaic (PV) mounting supports are used to fix PV panels to rooftops, ground surfaces, or other load-bearing surfaces, and are a common support structure in PV power generation systems. With the increasing application of distributed PV power generation, lightweight plastic support frames that are easy to install quickly on-site are gaining importance.

[0003] In the existing technology, when using a flat support frame to install a photovoltaic panel array, the operator first places the first photovoltaic panel on the support frame, uses a ruler to measure the distance between its side and the end of the vertical frame and adjusts it for alignment. Then, the second photovoltaic panel is placed, and the distance is measured and adjusted again with a ruler so that its side is on the same straight line as the side of the first photovoltaic panel. In this way, a ruler needs to be used to measure each time a photovoltaic panel is installed. Summary of the Invention

[0004] The purpose of this invention is to provide a flat, lightweight plastic photovoltaic installation support frame to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A flat, lightweight plastic photovoltaic mounting support frame, including

[0007] Two crossbars;

[0008] Two longitudinal frames, each detachably connected between the top two sides of the two transverse frames;

[0009] A clamping mechanism, which is adjustablely mounted on the longitudinal frame;

[0010] A locking mechanism is adjustablely mounted on the crossbeam.

[0011] Furthermore, the clamping mechanism includes a T-shaped groove opened along the length of the longitudinal frame, and several T-shaped blocks slidably fitted in the T-shaped groove. A rectangular clamping plate is also slidably fitted inside the lower part of the T-shaped groove. A clamping block is detachably provided at the top of the T-shaped block. A coaxial through hole is opened through the middle part of the clamping block and the T-shaped block, and a locking screw is inserted through the through hole. A threaded hole that is threadedly fitted with the locking screw is opened through the middle part of the rectangular clamping plate.

[0012] Furthermore, a cross-shaped positioning groove is provided at the top of the T-shaped block, and a cross-shaped positioning block that matches the cross-shaped positioning groove is fixedly connected to the middle of the bottom end of the clamping block.

[0013] Furthermore, the clamping block is fixedly connected to the top side wall of the clamping block. The inclined block may be provided only on one side of the top of the clamping block, or symmetrically provided on both sides of the top of the clamping block.

[0014] Furthermore, the upper surfaces of both sides of the top of the vertical frame are evenly distributed with scale two, and pointers that cooperate with scale two are fixedly connected to the outer walls of both sides of the T-shaped block.

[0015] Furthermore, the locking mechanism includes fixed seats fixedly connected to both sides of the top of the cross frame, a crossbar fixedly connected between the two fixed seats, sliders fixedly connected to both sides of the bottom of the longitudinal frame, and a guide hole that passes through the middle of the slider and slides with the crossbar. Clamping sleeves are fixedly connected to both ends of the slider and outside the guide hole. Nuts are fitted on the outside of the clamping sleeves, and external threads that engage with the nuts are opened on the outer wall of the clamping sleeves.

[0016] Furthermore, the nut has several insertion holes evenly distributed around its outer periphery.

[0017] Furthermore, a scale is provided on the surface of the crossbar along its length, and mounting ear plates are fixedly connected to the outer sides of both sides of the crossbar.

[0018] Compared with the prior art, the beneficial effects of the present invention are:

[0019] 1. This invention allows for the direct determination of the photovoltaic panel's placement position by using the pointer and scale two together, eliminating the need for a ruler. The scale on the vertical frame aligns with the pointer on the T-block, and the photovoltaic panel's side edge corresponds to the scale line to complete the positioning, avoiding the tedious operation of measuring each panel individually.

[0020] 2. This invention uses the detachable combination of T-shaped blocks and clamping blocks. When placing adjacent photovoltaic panels, the clamping blocks can be installed first, and the T-shaped blocks can be used for abutment and positioning only. This avoids the inclined blocks of the clamping blocks interfering with the placement of the photovoltaic panels. When placing a new photovoltaic panel, since the inclined blocks have not yet been installed, the photovoltaic panel can smoothly abut against the T-shaped blocks. After it is in place, the clamping blocks are installed and locked. Throughout the process, the inclined blocks will not obstruct the placement of the panels. Attached Figure Description

[0028] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0029] like Figure 1-6 As shown, the present invention provides a technical solution:

[0030] A flat, lightweight plastic photovoltaic mounting support frame includes two horizontal frames 1, with mounting lugs 18 fixedly connected to the outer sides of both sides of the horizontal frames 1; two vertical frames 2, each detachably connected between the top sides of the two horizontal frames 1; and a clamping mechanism, adjustablely mounted on the vertical frames 2. The clamping mechanism includes a T-shaped groove 3 extending along the length of the vertical frame 2, and several T-shaped blocks 4 slidably fitted within the T-shaped groove 3. A rectangular clamping plate 5 is also slidably fitted inside the lower part of the T-shaped groove 3. A clamping block 6 is detachably mounted on the top of the T-shaped block 4. Coaxial through holes 20 are respectively opened through the middle portions of the clamping block 6 and the T-shaped block 4. A locking screw 7 passes through the through hole 20. A threaded hole 21, threaded with the locking screw 7, is opened through the middle portion of the rectangular clamping plate 5. A cross-shaped positioning groove 8 is opened on the top of the T-shaped block 4. A cross-shaped positioning block 9, matching the cross-shaped positioning groove 8, is fixedly connected to the middle of the bottom end of the clamping block 6. An inclined block 22 is fixedly connected to the top side wall of the clamping block 6. Block 22 can be located only on one side of the top of clamping block 6, or symmetrically located on both sides of the top of clamping block 6. Scales 19 are evenly distributed on the upper surface of both sides of the top of the longitudinal frame 2. Pointers 10, which cooperate with scales 19, are fixedly connected to the outer walls of both sides of the T-shaped block 4. A locking mechanism, adjustablely mounted on the transverse frame 1, includes fixed seats 11 fixedly connected to both sides of the top of the transverse frame 1, a crossbar 12 fixedly connected between the two fixed seats 11, and a crossbar 12 fixedly connected to... The sliders 13 on both sides of the bottom end of the longitudinal frame 2 and the guide hole 23 that is opened through the middle of the slider 13 and slides with the crossbar 12 are fixedly connected to the two ends of the slider 13 and outside the guide hole 23. The clamping sleeve 14 is fitted with a nut 15 on the outside of the clamping sleeve 14. The outer wall of the clamping sleeve 14 is provided with an external thread that is threaded with the nut 15. Several insertion holes 16 are evenly distributed on the outer circumference of the nut 15. The crossbar 12 is provided with a scale 17 along the length direction.

[0031] Preferably, the horizontal frame 1, the vertical frame 2, the T-shaped block 4, the clamping block 6, and the rectangular clamping plate 5 are all injection molded from engineering plastics.

[0032] Preferably, the bottom of the inner wall of the T-groove 3 is provided with a serrated anti-slip pattern along its length, and the bottom surface of the rectangular clamp 5 is provided with anti-slip teeth that match the serrated anti-slip pattern. When the locking screw 7 is tightened, the rectangular clamp 5 presses against the inner wall of the T-groove 3, and the anti-slip teeth engage with the anti-slip pattern, which can effectively prevent slippage and loosening under long-term outdoor vibration.

[0033] Preferably, the inclined block 22 of the clamping block 6 presses against the side wall surface of the photovoltaic panel with an elastic buffer pad, which is made of EPDM rubber or silicone rubber. The buffer pad is 1mm to 3mm thick and has anti-slip protrusions on its surface. The elastic buffer pad can prevent the inclined block 22 from making hard contact with the side of the photovoltaic panel, thus avoiding scratches or microcracks, while providing elastic preload.

[0034] Preferably, the threaded section of the locking screw 7 adopts a trapezoidal thread with a tooth profile angle of 30°, a pitch of 3mm, and a thread helix angle of 4° to 6°. The trapezoidal thread forms a sliding fit with the threaded hole 21 of the rectangular clamping plate 5, with a fit clearance of 0.2mm to 0.4mm. This structure can adaptively compensate for slight displacement of the photovoltaic panel due to thermal expansion and contraction by utilizing the axial clearance of the trapezoidal thread, avoiding damage or loosening of the photovoltaic panel caused by sudden changes in clamping force. At the same time, the large tooth profile angle of the trapezoidal thread ensures that it is not easily dislodged by vibration during long-term use.

[0035] Preferably, the mounting ear plate 18 and the cross frame 1 are integrally injection molded structures, and a metal reinforcing insert is embedded in the middle of the mounting ear plate 18. The metal reinforcing insert is an internally threaded copper sleeve or a galvanized steel plate with through holes. This can improve the tensile strength and creep resistance of the mounting ear plate 18 at the bolt fixing point while ensuring overall lightweight design.

[0036] Preferably, both the horizontal frame 1 and the vertical frame 2 have hollow interiors, with intersecting reinforcing ribs arranged within the hollow structure. The thickness of the reinforcing ribs is 1.5mm to 2.5mm, and the density of the reinforcing ribs is no less than 3 per square centimeter. The hollow reinforced structure can further reduce the overall weight and material cost while ensuring structural strength.

[0037] Preferably, the bottom sides of the T-block 4 are provided with chamfered guide surfaces, and the sides of the T-slot 3 are provided with guide slopes that match the chamfered guide surfaces. This structure facilitates the smooth sliding of the T-block 4 from the end of the T-slot 3, avoiding jamming caused by burrs or slight deformation.

[0038] Preferably, pointer 10 and T-block 4 are integrally injection molded, and the tip of pointer 10 is coated with a fluorescent coating or high-contrast paint. The scale lines of scale 19 are also coated with a corresponding fluorescent coating. This design facilitates rapid reading and positioning in low-light installation environments.

[0039] Preferably, the scale 17 on the surface of the crossbar 12 and the longitudinal frame 2 is a permanent scale, either concave or convex, with a scale accuracy of ±1mm.

[0040] In this embodiment, by using pointer 10 and scale 19 together, the placement position of the photovoltaic panel can be determined directly by referring to the scale, without the need to use a ruler for measurement. The scale on the vertical frame 2 is aligned with pointer 10 on the T-block 4, and the photovoltaic panel can be positioned by corresponding to the scale line on the side, thus avoiding the tedious operation of measuring each panel one by one.

[0041] By using the detachable combination of T-block 4 and clamping block 6, clamping block 6 can be used without first installing it when placing adjacent photovoltaic panels. Instead, T-block 4 can be used as a support and positioning block to avoid interference from the inclined block 22 of clamping block 6 when placing the photovoltaic panel. When placing a new photovoltaic panel, since the inclined block 22 has not yet been installed, the photovoltaic panel can smoothly rest against T-block 4. After it is in place, clamping block 6 can be installed and locked. Throughout the process, the inclined block 22 will not obstruct the placement of the panel.

[0042] Working principle: During installation, firstly, the cross frame 1 is fixed in the preset position by installing the ear plate 18. Referring to the scale 17 on the surface of the cross bar 12, the nut 15 is loosened and the slider 13 is slid along the cross bar 12 to adjust the distance between the longitudinal frame 2 and the cross frame 1. Then, the nut 15 is tightened so that the clamping sleeve 14 clamps the cross bar 12 to complete the locking. Then, according to the scale 19 evenly distributed on the top surface of the longitudinal frame 2, the first photovoltaic panel is placed directly on the longitudinal frame 2 and the side of the photovoltaic panel is aligned with the scale 19. The corresponding scale line 19 does not require measurement with a ruler; on one side of the first photovoltaic panel, the clamping block 6 of the single-sided inclined block 22 is used to insert the cross-shaped positioning block 9 into the cross-shaped positioning groove 8 of the T-shaped block 4, and the locking screw 7 is passed through the through hole 20 of the clamping block 6 and the T-shaped block 4 in sequence and then screwed into the threaded hole 21 of the rectangular clamping plate 5. Tightening the locking screw 7 makes the rectangular clamping plate 5 press against the inner wall of the T-shaped groove 3, and at the same time, the inclined block 22 of the clamping block 6 presses the side of the photovoltaic panel; on the first photovoltaic panel... On the other side of the photovoltaic panel, first slide a T-shaped block 4 along the T-shaped groove 3 to a position close to the side of the first photovoltaic panel. Then place the second photovoltaic panel so that the side of the second photovoltaic panel abuts against the T-shaped block 4. At this time, install the clamping block 6 with symmetrical double inclined blocks 22 on the T-shaped block 4. Insert the cross-shaped positioning block 9 into the cross-shaped positioning groove 8. After the locking screw 7 passes through the through hole 20, screw it into the threaded hole 21 of the rectangular clamping plate 5 and tighten it. Tighten the locking screw 7 to make the rectangular clamping plate 5 press upward. The inner wall of the T-shaped groove 3 allows the double inclined blocks 22 to simultaneously press the other side of the first photovoltaic panel and the side of the second photovoltaic panel. When installing them side by side, before placing each new photovoltaic panel, first place a T-shaped block 4 against the unclamped side of the already installed photovoltaic panel, then place the new photovoltaic panel against the T-shaped block 4, and then install the clamping blocks 6 of the symmetrical double inclined blocks 22 and tighten the locking screws 7. This process completes the clamping and fixing of all photovoltaic panels in sequence. There is no need to use a ruler to measure the position of the photovoltaic panels during the entire process.
