Description

Technical Field

[0001] The invention relates to the field of mounting brackets, in particular to a self-adaptive adjustable photovoltaic component mounting bracket. Background Art

[0002] The photovoltaic module mounting bracket is a special bracket used for installing, placing, carrying, fixing and adjusting photovoltaic modules in photovoltaic power stations and other photovoltaic module fields. Together with photovoltaic modules, combiner boxes, inverters and other core equipment, it constitutes a photovoltaic power generation system. As an important supporting structure for photovoltaic modules, the safety and convenience of installation of the photovoltaic bracket are core requirements.

[0003] At present, in order to adapt to the terrain, most photovoltaic mounting brackets are distributed discretely, and the installation problem of uneven terrain is solved by adjusting the height of the column. For example, multiple adjustment mounting pin holes are set on the column, and the height adjustment is achieved by the cooperation of the pin shaft and the pin hole. This adjustment method cannot achieve self-adaptation, or can only adapt to a small angle adjustment range. It is difficult to meet the construction requirements of projects with large changes in ground height, and it is also impossible to avoid the impact of ground subsidence on system reliability, and it is even more impossible to meet the angle changes in any direction in space. The existing tracking brackets need to drive the panel to rotate in real time according to the changes in the solar altitude angle, so it is technically difficult to adapt to mountainous terrain and ground subsidence. At the same time, the technical solution of using the column of the bracket to adapt to the slope so that the main shaft can rotate and install on the column is time-consuming and labor-intensive, and inconvenient to install. Summary of the invention

[0004] 1. Technical issues to be resolved

[0005] In view of the deficiencies in the prior art, the present invention provides an adaptively adjustable photovoltaic module mounting bracket, which solves the problem that the photovoltaic bracket in the prior art cannot be adaptive, or can only adaptively adjust a small angle, making it difficult to meet the construction requirements of project sites with large changes in ground height, and cannot meet the angle changes in any direction in space.

Moving assemblies are installed on both sides of the outer wall of the adjustment screw;

[0009] The auxiliary support mechanism comprises an outer cylinder, an inner block is movably sleeved inside the outer cylinder, a fixed shaft is fixedly arranged on the rear end surface of the inner block, and connecting springs are fixedly arranged on the front and rear ends of the lower end surface, the bracket assembly comprises a bottom block, a mounting plate is fixedly arranged on the upper end of the bottom block, connecting blocks are fixedly arranged on the front and rear ends of the lower end surface of the mounting plate away from the bottom block, and a No. 2 shaft is rotatably arranged in the two connecting blocks, and a linkage rod is sleeved on the outer wall shaft of the No. 2 shaft;

[0010] The moving assembly comprises a moving block, which is threadedly sleeved on the outside of the adjusting screw and has connecting shafts fixedly arranged on one side of the front and rear ends of the outer wall of the moving block.

[0011] Preferably, one end of the adjusting screw passes through one side of the outer wall of the adjusting seat, the front and rear ends of the adjusting seat are both provided with through holes, and the connecting shaft passes through the through holes and is rotatably sleeved with the linkage rod.

[0012] Preferably, a through groove is provided on one side of the upper end surface of the top plate close to the bottom block, and the bottom block is fixedly sleeved on the No. 1 shaft.

[0013] Preferably, the worm is meshingly connected with the worm wheel, and a movable groove is provided at the front and rear ends of the upper end of the bottom plate at the lower end of the connecting plate, and the connecting plate is embedded in the movable groove when flipping.

[0014] Preferably, one end of the connecting plate away from the fourth axis is rotatably sleeved with the fixed axis, and a groove is provided on one side of the outer wall of the outer cylinder, and the position of the groove corresponds to the upper and lower parts of the connecting plate.

[0016] Preferably, the adjusting screw is a bidirectional threaded rod.

[0017] Working principle: When using the mounting bracket, first use the bracket legs at the lower end to install it to the specified position, then install the photovoltaic module on the mounting plate of the bracket assembly at the upper end. After the photovoltaic module is installed and fixed, it can be adaptively adjusted according to the specific situation, including adjusting the inclination angle of the mounting plate and the angle of the top plate;

[0018] The specific operation of adjusting the inclination angle of the mounting plate is as follows: after the photovoltaic module is fixed on the upper end of the mounting plate, the moving block with the threaded sleeve is driven to move by twisting the adjusting screw, and the movement of the moving block drives the outer connecting shaft to move. Since the lower end of the mounting plate is connected to the connecting shaft by the connecting block, the second shaft and the linkage rod, and the bottom block on the other side of the lower end of the mounting plate is rotatably arranged on the side block by the first shaft, when the moving block is displaced, the linkage rod is pulled to move, and the other end is rotatably connected by the first shaft, so that the tilt angle is changed by the flipping movement, thereby achieving the desired angle adjustment;

[0019] The specific operation for adjusting the angle of the top plate is as follows: after completing the inclination adjustment of the upper bracket assembly, the worm is driven to rotate by twisting the adjusting rod, and the No. 3 shaft connected to the inner side of the worm gear rotates to drive the outer top plate to flip and tilt. Since an auxiliary support mechanism is provided on the other side of the top plate, the connecting spring inside the auxiliary support mechanism ensures its retractability and a connecting plate linked to the auxiliary support mechanism is provided at the lower end. When the top plate flips, the inclination angle of the connecting plate changes synchronously, which not only provides an auxiliary support effect, but also enables linkage operation functions between multiple components.

[0020] (III) Beneficial effects

[0022] The present invention provides an adaptively adjustable photovoltaic component mounting bracket, which fixes the photovoltaic component on a mounting plate when in use, and the mounting plate is connected to the moving component at the lower end by an adjusting screw, an adjusting component, and a linkage rod so that the posture of the mounting plate can adaptively track the adjustment of the pitch angle of the photovoltaic bracket; at the same time, since the bracket assembly is mounted on the top plate, the top plate is fixedly connected to the third axis, and the top plate is driven to move when the third axis rotates, and the auxiliary support mechanism arranged at the lower end of the top plate performs an auxiliary support effect during the adjustment process, thereby ensuring the stability of its installation, so that it can rotate within a certain angle range during the installation process, and then the photovoltaic component can be set to the required installation angle according to actual needs. When the photovoltaic bracket is installed in a site with a slope, the mounting bracket can further adapt to the slope terrain. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0030] 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.

[0031] Example:

[0032] like Figure 1-6 As shown, the embodiment of the present invention provides an adaptively adjustable photovoltaic module mounting bracket, including a bottom plate 4 and a top plate 15, a fixing plate 11 is fixedly arranged on one side of the upper end surface of the bottom plate 4, a third shaft 19 is rotatably arranged at the front and rear sides of the fixing plate 11 near the upper end, a worm gear 18 is fixedly sleeved on one end of the third shaft 19, one side of the top plate 15 is fixedly sleeved on the third shaft 19, a mounting block 9 is fixedly arranged on one side of the front end surface of the bottom plate 4, an adjusting rod 10 is rotatably arranged on the mounting block 9, a worm 20 is fixedly arranged on the upper end of the adjusting rod 10, and the bottom plate Two side plates 23 are fixedly arranged at the front and rear ends of one side of the upper end surface of the bottom plate 4. A fourth shaft 22 is rotatably arranged between the two side plates 23 on the front and rear sides of the four side plates 23. A connecting plate 7 is fixedly sleeved on the outer side of the fourth shaft 22. Auxiliary support mechanisms 1 are installed at the front and rear ends of the upper end surface of the bottom plate 4 away from the fixed plate 11; the worm 20 is meshed and connected with the worm wheel 18. A movable groove 5 is opened at the front and rear ends of the upper end of the bottom plate 4 at the lower end of the connecting plate 7. When the connecting plate 7 performs a flipping movement, it is embedded in the movable groove 5.

[0033] Specifically, when in use, the worm 20 at the upper end is driven to rotate by twisting the adjusting rod 10, and the rotation of the worm 20 drives the meshing worm wheel 18 to rotate, and the third shaft 19 fixed on the inner side of the worm wheel 18 rotates accordingly, and when the third shaft 19 rotates, it drives the connected top plate 15 to flip together, and the auxiliary support mechanism 1 located on the bottom plate 4 provides auxiliary support force for the top plate 15, so that it can not only realize the rapid adjustment of the angle posture of the top plate 15, but also ensure that the adjusted top plate 15 is in a stable state, effectively providing a supporting effect.

[0034] The auxiliary support mechanism 1 includes an outer cylinder 102, an inner block 101 is movably sleeved inside the outer cylinder 102, a fixed shaft 103 is fixedly arranged on the rear end surface of the inner block 101, and a connecting spring 104 is fixedly arranged on the front and rear ends of the lower end surface, and one end of the connecting plate 7 away from the fourth shaft 22 is rotatably sleeved with the fixed shaft 103, and a groove 21 is opened on one side of the outer wall of the outer cylinder 102, and the position of the groove 21 corresponds to the upper and lower sides of the connecting plate 7;

[0035] Specifically, the upper end of the inner block 101 is fixedly connected to the lower end of the top plate 15, and the inner block 101 cooperates with the connecting spring 104 and the outer cylinder 102 to provide auxiliary support for the top plate 15. Since the connecting spring 104 is retractable, the retractability of the top plate 15 during pitch adjustment can be achieved, and since the connecting plate 7 is connected to the outer fixed shaft 103, the inner block 101 completes the change in the angle of inclination of the connecting plate 7 when following the top plate 15 to adjust the pitch.

[0036] Reference Figure 1-Figure 2 Side blocks 12 are fixedly provided at the front and rear ends of both sides of the upper end surface of the top plate 15, and a No. 1 shaft 13 is rotatably provided on one side of the front and rear ends of the two side blocks 12 on both sides, and a bracket assembly 14 is fixedly sleeved on the outer sides of the two No. 1 shafts 13. An adjustment seat 2 is fixedly provided at the midpoint of the upper end surface of the top plate 15, and an adjusting screw 3 is rotatably provided at the midpoint of one side of the inner wall of the adjusting seat 2, and moving assemblies 6 are installed on both sides of the outer wall of the adjusting screw 3, and the adjusting screw 3 adopts a bidirectional threaded rod.

[0037] Specifically, when in use, the movable assembly 6 with threads on both sides can be quickly moved laterally by twisting the adjusting screw 3; and since the bracket assembly 14 is fixed on the No. 1 shaft 13, the No. 1 shaft 13 is rotatably sleeved inside the side block 12, that is, the No. 1 shaft 13 can rotate, thereby driving the bracket assembly 14 connected on the outside to flip over.

[0038] Reference Figure 1-Figure 2 , the moving assembly 6 includes a moving block 602, the moving block 602 is threadedly sleeved on the outside of the adjusting screw 3, and a connecting shaft 601 is fixedly arranged on one side of the front and rear ends of the outer wall of the moving block 602, one end of the adjusting screw 3 passes through one side of the outer wall of the adjusting seat 2, and the front and rear ends of the adjusting seat 2 are provided with a through hole 16, and the connecting shaft 601 passes through the through hole 16 and is rotatably sleeved with the linkage rod 1405; the bracket assembly 14 includes a bottom block 1401, a mounting plate 1402 is fixedly arranged on the upper end of the bottom block 1401, and a connecting block 1403 is fixedly arranged at the front and rear ends of the lower end surface of the mounting plate 1402 away from the bottom block 1401, and a second shaft 1404 is rotatably arranged in the two connecting blocks 1403, and a linkage rod 1405 is sleeved on the outer wall shaft of the second shaft 1404, and a through groove 17 is opened on the upper end surface of the top plate 15 close to the bottom block 1401, and the bottom block 1401 is fixedly sleeved on the first shaft 13;

[0039] Specifically, when in use, twisting the adjusting screw 3 drives the outer moving block 602 to move laterally, the moving block 602 moves in the adjusting seat 2 and the connecting shafts 601 on the front and rear sides translate laterally in the through hole 16. Since the linkage rod 1405 is connected to the connecting shaft 601, when the connecting shaft 601 moves laterally, a pulling force is generated on the linkage rod 1405, and the other end of the linkage rod 1405 is rotationally connected to the second shaft 1404. At this time, the inclination angle of the linkage rod 1405 changes, resulting in a change in the height of the second shaft 1404 at the upper end, and then causing the height of the upper mounting plate 1402 to change. One end of the mounting plate 1402 is connected to the first shaft 13, and finally the rotation of the first shaft 13 and the change of the pitch angle of the mounting plate 1402 are realized.

[0040] Reference Figure 1 , bracket legs 8 are fixedly provided at the front and rear ends of both sides of the lower end surface of the bottom plate 4;

[0041] Specifically, when the mounting bracket is installed and used, the bracket leg 8 at the lower end is fixed at a specified position to complete the rapid positioning and installation.
