Description

Technical Field

[0001] The present application relates to the field of photovoltaic power generation technology, and specifically to a photovoltaic bracket. Background Art

[0002] Especially in recent years, with the increasing number of electric vehicles in my country, the batteries of electric vehicles need to be charged frequently, and the power consumption is large. Therefore, providing charging facilities for electric vehicle batteries in carports or parking spaces has become a problem that electric vehicle families must consider. Now some carports or parking spaces have been equipped with charging piles for charging electric vehicles as needed. These charging piles are generally powered by municipal power, which consumes a lot of electricity and causes energy waste. Therefore, more and more families choose to use solar photovoltaic power generation and charge electric vehicle batteries. In order to improve the photoelectric conversion rate of solar photovoltaic, most of the current solar photovoltaic brackets are set to track the angle of sunlight. The most common is a dual-axis tracking photovoltaic bracket, that is, the solar panels on the photovoltaic bracket can be driven by the driving mechanism to rotate around two mutually perpendicular axes to adjust the angle, so that the solar panels can rotate with the change of the angle of sunlight, thereby improving the photoelectric conversion rate of solar photovoltaic.

[0003] The structure of the dual-axis tracking photovoltaic bracket in the related technology includes a base installed on the ground, a column connected to the base, a rotating bracket and a driving mechanism for driving the rotating bracket to rotate to adjust the angle are installed on the upper end of the column, and a solar panel assembly is installed on the rotating bracket; the driving mechanism is generally two electric push rods, one electric push rod can drive the solar panel assembly to rotate around a first axis, and the other electric push rod can drive the solar panel assembly to rotate around a second axis, and the rotation axis of the first axis is perpendicular to the rotation axis of the second axis, such as the photovoltaic bracket in the patent application with publication number CN116795145A. The dual-axis tracking photovoltaic bracket of the related technology has the following defects during actual use: most of the supporting force of the solar panel assembly and the driving force for angle adjustment are provided by the electric push rod. In addition, the photovoltaic bracket is outdoors and is often exposed to wind and rain. Therefore, the electric push rod will fail after working for a certain period of time, which requires disassembly and replacement or disassembly for inspection; and when disassembling and replacing the electric push rod, the extension length of the failed electric push rod is uncertain, so the maintenance personnel need to fix the rotating bracket with a positioning rod in advance to make the rotating bracket in a stationary state, and then disassemble and replace the electric push rod. The operation is very troublesome, and the disassembly and replacement operation is time-consuming and laborious. In addition, because the rotating bracket carries the solar panel assembly, the overall weight is heavy, and it is difficult to fix it firmly with a positioning rod. Utility Model Content

[0039] Therefore, in this embodiment, a mounting position for installing a spare electric push rod is provided between the column assembly 2 and the first frame 300, and / or a mounting position for installing a spare electric push rod is provided between the first frame 300 and the second frame 302. In this way, when the first electric push rod 301 and / or the second electric push rod 303 fails and needs to be disassembled and replaced or disassembled for repair, it is only necessary to install a new spare electric push rod on the mounting position between the column assembly 2 and the first frame 300, and then disassemble the first electric push rod 301, and / or install a new spare electric push rod on the mounting position between the first frame 300 and the second frame 302, and then disassemble the second electric push rod 303. The entire disassembly and replacement process of the electric push rod does not require additional fixing of the first frame 300 and the second frame 302, so the operation is simple and labor-saving; furthermore, when the spare electric push rod is installed on the mounting position, it can replace the failed electric push rod, and at this time, it is only necessary to disassemble the failed electric push rod, making it very convenient to disassemble and replace the failed electric push rod.

[0040] In this embodiment, if Figure 2 , Figure 3 and Figure 4 As shown, the first frame 300 includes a horizontal arm 305 and an inclined arm 306 connected to one end of the horizontal arm 305. The horizontal arm 305 and the inclined arm 306 are arranged in an L shape as a whole. The portion between the horizontal arm 305 and the inclined arm 306 is rotatably connected to the upper end of the second rod 201 of the column assembly 2 through a rotating shaft 307. The upper connecting seat of the first connecting seat 308 and the upper connecting seat of the second connecting seat 309 are both connected to the outer end of the horizontal arm 305, and the lower connecting seat of the first connecting seat 308 and the lower connecting seat of the second connecting seat 309 are both connected to the column assembly 2. Further, the upper connecting seat of the third connecting seat 310 and the upper connecting seat of the fourth connecting seat 311 are both connected to the second frame 302, and the lower connecting seat of the third connecting seat 310 and the lower connecting seat of the fourth connecting seat 311 are both connected to the outer end of the inclined arm 306. That is, a spare electric push rod installation position is set on one side of the first electric push rod 301, and a spare electric push rod installation position is set on one side of the second electric push rod 303. The structure is simple and compact. The spare electric push rod installation position is set together with the first electric push rod 301 or the second electric push rod 303, which makes the operation more convenient when disassembling and replacing the electric push rod.

[0041] In this embodiment, if Figure 3As shown, the second frame 302 includes a beam 312 and a mounting frame 313 connected to the beam 312 for installing the solar panel 4 assembly; a rotating seat 314 is connected to the first frame 300, the beam 312 is arranged parallel to the horizontal arm 305 of the first frame 300, the beam 312 is rotatably connected to the rotating seat 314, and the rotation axis of the beam 312 coincides with the rotation axis of the second frame 302; specifically, the rotating seat 314 includes two parts, namely, a plurality of annular supports fixedly connected to the first frame 300 and a plurality of annular rotating blocks fixedly connected to the beam 312, the annular rotating blocks are rotatably connected in the inner holes of the annular supports one by one, so that the beam 312 can rotate around the axis of the rotating seat 314.

[0042] In some embodiments, Figure 3 As shown, a driving arm extending outward is connected to one side of the cross beam 312, and the upper connecting seat of the third connecting seat 310 and the upper connecting seat of the fourth connecting seat 311 are both connected to the driving arm. That is, the second electric push rod 303 drives the cross beam 312 to rotate by driving the driving arm.

[0043] In this embodiment, the first rod 200 and the second rod 201 are both hollow tubes, and the second rod 201 is slidably mounted on the first rod 200; Figure 1 , Figure 4 and Figure 5As shown, a driving assembly is connected to the column assembly 2, and the driving assembly is used to drive the second rod 201 to rise and fall relative to the first rod 200, so that the column assembly 2 has a lifting function. The driving assembly includes a winding wheel 5 with a handle 500, a cable 503 and at least one fixed pulley connected to the first rod 200, the winding wheel 5 is rotatably connected to the first rod 200, one end of the cable 503 is wound on the winding wheel 5, and the other end of the cable 503 is connected to the lower end of the second rod 201 after passing the fixed pulley; the photovoltaic bracket sets the column assembly 2 into two rods, namely the first rod 200 and the second rod 201 that can slide relative to the first rod 200; when the second rod 201 is at the lowest position, the height of the column assembly 2 is relatively high. The height of the solar panel 4 is low, and the user can save a lot of effort when installing, especially when erecting the column assembly 2; therefore, when installing the photovoltaic bracket, the second rod 201 can be lowered to the lowest height, the lower end of the first rod 200 of the column assembly 2 can be fixed to the ground, and then the rotating bracket 3 with the solar panel 4 can be installed on the upper end of the second rod 201, and finally the winding wheel 5 is rotated to wind the cable 503 to drive the second rod 201 to rise to the required or predetermined height. During the whole installation process, the installers are on the ground or at a lower height, so the safety is good, and the installation operation is simple, convenient and labor-saving. When the driving mechanism on the photovoltaic bracket is replaced or the solar panel 4 is overhauled, the second rod 201 can be lowered to the lowest height for easy maintenance and simple operation; furthermore, when encountering typhoons or strong winds, the second rod 201 can be lowered to the lowest height to reduce the shaking of the photovoltaic bracket by the wind and avoid damage to the photovoltaic bracket.

[0044] In this embodiment, if Figure 5 As shown, in order for the cable 503 to drive the second rod 201 to rise and fall smoothly when the winding wheel 5 is rotated, two fixed pulleys are provided: a first fixed pulley 501 and a second fixed pulley 502. The first fixed pulley 501 and the second fixed pulley 502 are respectively connected to the first rod 200 from top to bottom, and the first fixed pulley 501 is arranged near the upper end of the first rod 200, and the second fixed pulley 502 is arranged near the winding wheel 5; the cable 503 passes through the second fixed pulley 502 and the first fixed pulley 501 from bottom to top and is connected to the lower end of the second rod 201. In this embodiment, the first fixed pulley 501 and the second fixed pulley 502 are both installed on the first rod 200 through a pulley bracket and a screw. With the cooperation of the two fixed pulleys, the cable 503 can be prevented from being misplaced, so that the winding or release of the cable 503 is more stable, so that the second rod 201 can be smoothly raised and lowered.

[0045] In order to keep the second rod 201 fixed in the unfolded state or after it rises to a predetermined height, a locking mechanism is provided on the column assembly 2, and the locking mechanism is used to lock the second rod 201 on the first rod 200 after it rises to a predetermined height. In this embodiment, the locking mechanism is provided with a first positioning hole at the upper end of the first rod 200, and a second positioning hole corresponding to the first positioning hole is provided at the lower end of the second rod 201; when the second rod 201 is in the unfolded state relative to the first rod 200, the second positioning hole coincides with the first positioning hole 504 and is connected by a locking bolt.

[0046] For example, at least two groups of first positioning holes are provided at the upper end of the first rod 200, and at least two groups of second positioning holes corresponding thereto are provided at the lower end of the second rod 201. When the second rod 201 rises to a predetermined height, the at least two groups of second positioning holes are respectively aligned with the at least two groups of first positioning holes and are respectively fixed by locking bolts.

[0047] In other embodiments, the locking mechanism may also be at least one cam wrench disposed on the second rod 201 , and the cam portion of the cam wrench is pressed against the surface of the first rod 200 by rotating the cam wrench, thereby fixing the second rod 201 on the first rod 200 .
