[0034] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0035] The core of the present invention is to provide a tracking system solar panel module installation mechanism that is easy to install and can stably install solar panels.

[0036] Please refer to Figures 1 to 12 , Figure 1 A schematic diagram of a solar panel module installation mechanism for a tracking system provided by the present invention; Figure 2 A schematic diagram of the connection between the main shaft and the diagonal brace provided by the present invention; Figure 3 A schematic diagram of a tensioning device provided by the present invention; Figure 4 A schematic diagram of a support block provided by the present invention; Figure 5 A front view of the support block provided by the present invention; Figure 6 A side view of the support block provided by the present invention; Figure 7 A top view of the support block provided by the present invention; Figure 8 This is a schematic diagram of the installation of the support block, the clamp and the support plate provided by the present invention; Fig. 9 A schematic diagram of an oblong hole provided by the present invention; Fig.10 A schematic diagram of a card provided by the present invention; Fig.11 A schematic diagram of a positioning block provided by the present invention; Fig.12 This is a schematic diagram of the clamp provided by the present invention.

[0037] A tracking system solar panel module installation mechanism includes: a plurality of parallel arranged rails 11 for supporting solar panels 1 and a main shaft 7 for supporting the plurality of rails 11, the rails 11 are provided with positioning devices for positioning the solar panels 1, the rails 11 are provided with a plurality of clamping devices for clamping the solar panels 1 along the length direction of the rails 11, and the main shaft 7 is provided with a diagonal brace 6 for stabilizing the rails 11.

[0038] It should be noted that the purlin is in an I-shaped, door-shaped or other shape, with openings at the connection position, and the diagonal brace 6 is in a C-shaped, I-shaped, rectangular, etc. One end of the diagonal brace 6 is hinged to the purlin through a fastener, and the other end is fixed to the diagonal brace 6 connecting piece. The hinge point at the connection between the diagonal brace 6 and the purlin is an oblong hole 9, so that after pre-installation at the factory, on-site installation is convenient to adapt to the processing deviation of the main shaft 7, thereby improving the convenience of installation.

[0039] The back panel fixing strength of the tracking bracket in the prior art is insufficient, the pressure block installation cannot limit the sliding, and the installation of the back panel pressure block is cumbersome and costly. The patent has efficient installation, economical manufacturing, and high strength. Except for the solar panel 1, other components can be pre-assembled in the factory and then shipped to the site for installation, saving on-site labor costs.

[0040] The present invention can limit six degrees of freedom of the solar panel 1 , while the traditional pressing block can only limit four degrees of freedom. Compared with the prior art, the present invention has stronger stability for the solar panel 1 .

[0041] The main shaft 7 is connected to the bottom of several sandalwood bars 11 for supporting the sandalwood bars 11. In order to stably support the sandalwood bars 11, a diagonal brace 6 for stably supporting the sandalwood bars 11 is provided on the main shaft 7. The sandalwood bars 11 are used as a skeleton to support the solar panel 1. The positioning device provided on the sandalwood bars 11 can stably place the solar panel 1 on the sandalwood bars 11, and can prevent the solar panel 1 from shaking at will. Then, several clamping devices are used to clamp the solar panel 1 on the sandalwood bars 11 to further stabilize the solar panel 1. The present invention uses a positioning device for positioning and uses several clamping devices for clamping to install the solar panel 1. No other fasteners are required, which avoids the shaking of the solar panel 1 caused by the inadequate tightening of the fasteners. In addition, the present invention has a simple structure, which can reduce the installation time and reduce the installation labor cost.

[0042] On the basis of the above embodiment, as a further preference, the clamping device includes a support plate 4 installed on the sandalwood bar 11 and a clamp 2 installed on the support plate 4, and the clamp 2 is provided with a first curved portion facing the surface of the solar panel 1 and capable of clamping the surface of the solar panel 1.

[0043] It should be noted that the support plate 4 can be clamped on the wooden bar 11, and the support plate 4 can be installed on the wooden bar 11 using fasteners such as bolts, rivets, and pins. The support plate 4 can be self-positioned and can limit the planar freedom of the solar panel 1 to prevent the components from loosening and sliding down. The positioning can be completed by tightening the fasteners during installation.

[0044] The pressing block can be installed on the support plate 4 using fasteners such as bolts, rivets, and pins. After pre-installation, it is delivered to the site for installation, and only one fastener needs to be installed.

[0045] The clamp 2 is made of metal and has a certain elasticity. The first curved portion is elastically deformed to increase the distance between the first curved portion and the support plate 4, and then the solar panel 1 is loaded. The first curved portion rebounds and presses and fixes the solar panel 1. The metal clamp 2 pierces the frame of the solar panel 1 after being pressed, achieving a grounding and conduction effect.

[0046] A single solar panel 1 and a clamp 2 are installed to form an independent module, thereby avoiding a chain reaction of overall failure caused by a single failure of a conventional pressing block.

[0047] On the basis of the above embodiment, as a further preference, the clamp 2 is a horn-shaped clamp 2 having a first curved portion and a second curved portion bent toward both sides, and a support block 3 for stabilizing the clamp 2 is provided between the second curved portion and the support plate 4.

[0048] It should be noted that in order to improve the application capabilities of the clips 2 and the pallets 4, since a plurality of clips 2 and pallets 4 are provided along the length direction of the sandalwood strip 11, and one clip 2 corresponds to one pallet 4, a support block 3 is provided between the second bent portion of the clip 2 at the end of the arrangement direction of the clip 2 and the pallet 4, so as to improve the stability of the fixation of the clip 2 and improve the overall reliability.

[0049] The clamp 2 and the support plate 4 are fixed to the purlin by fasteners. The clamp 2 is made of spring steel or other elastic materials and is in the shape of a horn. Both ends of the support plate 4 are raised toward the first curved portion to form a flange for positioning and shifting the solar panel 1 during installation. There are two protrusions on the bottom surface of the support plate 4 for clamping on the purlin bar 11, thereby increasing the stability of the installation.

[0050] During on-site construction, the main shaft 7 is connected to several parallel-arranged strips 11, with the intervals between the strips 11 being approximately the width of each solar panel 1. The solar panel 1 is then pushed between the clamp 2 and the support plate 4. The first bent portion of the clamp 2 is elastically deformed during pushing. After the solar panel 1 is in place, the lower frame is clamped in the flange, and the upper frame of the solar panel 1 is tightened by the first bent portion. The elastic deformation of the first bent portion is used to provide prestress for the installation of the solar panel 1. At the same time, the solar panel 1 is laid flat after being installed in place to ensure that the solar panel 1 will not fall out.

[0051] The clamping member 2 provided in this embodiment has a simple structure and fixes the solar panel 1 by clamping, which can improve installation efficiency and save labor costs.

[0052] On the basis of the above embodiments, as a further preference, the support block 3 is a convex-shaped support block 3, which includes a first step 21 and a second step 20, the width of the first step 21 is smaller than the width of the second step 20, the inner side surface of the second step 20 is pressed against the support plate 4, and the side of the first step 21 facing the horn-shaped clip 2 is provided with a folded edge 19, and the second bent portion is pressed against the folded edge 19.

[0053] It should be noted that the cross section of the convex support block 3 is convex, the second step 20 is below the first step 21, there is no sealing plate at the bottom of the second step 20, the inner side surface of the second step 20 is parallel to the sandalwood bar 11, and presses the support plate 4, the second curved portion presses the folding edge 19, the convex support block 3 is a special-shaped sheet metal part, when the convex support block 3 is installed, it is installed from the side of the clamp 2, after the second curved portion is pulled up, the inner side surface of the second step 20 is pressed against the support plate 4, and the second curved portion is aligned with the folding edge 19 and pressed. The convex support block 3 has a simple structure and is easy to process and install.

[0054] Based on the above embodiment, as a further preference, the end faces of the first curved portion and the second curved portion are both corrugated surfaces. After installation, the end face of the first curved portion contacts the solar panel 1, and the end face of the second curved portion contacts the folded edge 19. Providing corrugated surfaces on the end faces of the first curved portion and the second curved portion can increase friction.

[0055] On the basis of the above embodiment, as a further preference, the positioning device is a positioning block 5, and a positioning protrusion is provided along the edge of the positioning block 5. When the solar panel 1 is installed on the positioning block 5, the positioning protrusion is locked to position the frame at the bottom of the solar panel 1.

[0056] It should be noted that there is a flange under the positioning piece, which just catches the purlin, limiting the rotational freedom of the positioning piece relative to the purlin, and is hinged to the purlin through fasteners. The combined action of the flange and the fasteners firmly fixes the positioning piece and the purlin. There is also a protrusion or curling edge on the positioning piece, which is used for installation and positioning of the solar panel 1, and the protrusion or curling edge just catches the lower frame of the solar panel 1.

[0057] The positioning blocks 5 provided in this embodiment can make adjacent solar panels 1 easy to position and install quickly. The installation is simple and fast with low labor costs. The prestressing force makes the installation structure more solid and reliable.

[0058] On the basis of the above embodiment, as a further preference, a clamp 24 is installed on the main shaft 7 and is mounted on the outside of the main shaft 7. The outer periphery of the clamp 24 is provided with a first folding ear 23 for connecting the sandalwood bar 11 and a second folding ear 22 for connecting the diagonal brace 6 and the same number as the diagonal brace 6.

[0059] It should be noted that the purlins and diagonal braces 6 are installed on the clamps 24 to form a stable structure. One end of the diagonal brace 6 is installed on the purlin and the other end is installed on the folded ear, thereby ensuring that the diagonal brace 6 and the polygonal clamp 24 are both within the longitudinal projection of the purlin, and thus can be well adapted to both conventional components and double-glass bifacial components.

[0060] The clamp 24 provided in this embodiment has a simple structure and is easy to process and install.

[0061] On the basis of the above embodiment, as a further preference, the inner periphery of the clamp 24 is matched with the outer periphery of the main shaft 7. It should be noted that the clamp 24 can be installed in combination with the main shaft 7 of any profile such as round, triangular, rectangular, pentagonal, hexagonal, etc. The polygonal clamp 24 is made of a one-piece sheet metal bending and is made according to the cross-section of the connected main shaft 7. After installation, the clamp 24 fits with each surface of the main shaft 7 and is firmly installed. The clamp 24 fits with each surface of the main shaft 7 to limit the relative deflection of the main shaft 7 and the clamp 24.

[0062] On the basis of the above embodiment, as a further preferred embodiment, a tensioning device 8 for tightening or loosening the diagonal brace 6 is further provided on the main shaft 7. It should be noted that the tensioning device 8 can relatively tighten the two diagonal braces 6, apply prestress to the purlin, resist the deformation of the purlin bending downward under the load, improve the straightness of the purlin, and thus improve the protection of the solar panel 1.

[0063] On the basis of the above embodiment, as a further preference, the tensioning device 8 includes a mounting member 16 for being mounted on the outer periphery of the main shaft 7 and a tensioning rope 10 for tightening the diagonal brace 6, the two ends of the tensioning rope 10 are respectively connected to the diagonal braces 6 arranged on both sides of the main shaft 7, pulleys 14 for guiding the tensioning rope 10 are arranged on both sides of the mounting member 16, and an adjuster for adjusting the distance of the tensioning rope 10 relative to the mounting member 16 is also provided between the pulleys 14 on both sides.

[0064] It should be noted that the mounting member 16 is mounted on the outer periphery of the main shaft 7, and the pulleys 14 on both sides are mounted using mounting baffles 15. Mounting baffles 15 are provided on both sides of the pulley 14 on one side, and two pulleys 14 arranged vertically are provided between the two mounting baffles 15 on one side, and the pulleys 14 and mounting baffles 15 on both sides are symmetrically arranged about the regulator. The regulator includes a speed reducer 12 and a hand crank 13 and a rotating arm 18 provided on the speed reducer 12. The rotating arm 18 is provided with a tensioning wheel 17, and the tensioning wheel 17 can be of the same shape as the pulley 14. The speed reducer 12 is a worm gear transmission device. The two ends of the tensioning rope 10 are tied to the holes of the diagonal support 6, passing through the middle of the pulleys 14 arranged vertically at the mounting baffle 15, and the tensioning rope 10 bypasses the groove of the tensioning wheel 17 on the rotating arm 18 and passes through the middle of the pulleys 14 arranged vertically on the other side.

[0065] The hand crank 13 rotates to rotate the rotating arm 18, driving the pulley 14 thereon to rotate eccentrically, thereby achieving the tensioning of the tensioning rope 10. The tensioning device 8 tensions the tensioning rope 10, thereby tightening the diagonal brace 6, applying prestress to the purlin, resisting the deformation of the purlin bending downward under the load, improving the straightness of the purlin, and thus improving the protection of the components.
