Description

A double-push rod double-main-beam fixed adjustable photovoltaic bracket

Technical Field

The utility model belongs to the technical field of photovoltaic power generation, and in particular relates to a double-push-rod double-main-beam fixed adjustable photovoltaic bracket.

Background Art

As a renewable energy source that is abundant, widely distributed and permanently available, solar energy has great potential for development and utilization. The proportion of photovoltaic power generation capacity in the global energy supply has further increased. In the near future, it will become the main body of the world's energy supply, bringing revolutionary changes to energy development.

Photovoltaic brackets are one of the most critical contents and links in the construction of photovoltaic power stations. They are greatly affected by the construction conditions of the project site and the construction environment. They are large in quantity and wide in scope, and the construction period is long. At present, photovoltaic brackets are generally fixed or tracking. The construction and maintenance costs of tracking photovoltaic brackets are too high, and their promotion is limited; although the cost of fixed photovoltaic brackets is low, due to the different altitude angles of the sun in different seasons, the use of fixed brackets wastes a lot of solar energy.

The tilt angle of the fixed adjustable photovoltaic bracket is manually adjusted several times a year within a fixed period of time. This type of bracket structure is stable and reliable in operation. Compared with the fixed non-adjustable bracket, it only requires less investment to increase the power generation. Especially in the situation where the state's subsidies for photovoltaic power generation projects are reduced year by year and the power generation is advancing at parity, the optimization of power generation systems and the exploration of potential have received attention, and fixed adjustable brackets have become a good system solution.

However, most of the current fixed adjustable photovoltaic brackets usually use a main beam with a certain fixed inclination angle as the rotation axis, and then install transverse purlins on the main beam to fix the photovoltaic panels. As the power of the components increases, the size of the components also increases, thereby increasing the cantilever length of the purlins and reducing the stability of the purlins.

In addition, most of the current fixed adjustable photovoltaic brackets are fixed with bolt holes after the angle adjustment is completed. Therefore, not only is the adjustment angle controlled by the number of bolt holes, it is impossible to adjust any angle within the adjustment range. Therefore, compared with the tracking bracket, the photovoltaic conversion efficiency is limited. In addition, during the angle adjustment process, the locking component must be loosened first. After multiple people adjust to the required angle, multiple people pre-fix it, and then one of them locks the locking component to fix it. This adjustment method is time-consuming and labor-intensive, and has low work efficiency.

DETAILED DESCRIPTION

As shown in Figures 1-7, a double-push-rod double-main-beam fixed adjustable photovoltaic bracket includes a plurality of parallel and spaced columns 1 in the same straight line, two main beams 2 are symmetrically arranged above the columns 1, and the two main beams 2 are connected together by a plurality of inclined beams 3, and a plurality of purlins 4 for installing photovoltaic panels are arranged in parallel and spaced on the two main beams 2, and the purlins 4 are arranged perpendicular to the main beams 2, and the inclined beams 3 are arranged parallel to the purlins 4, the top of the column 1 is hinged to the inclined beam 3 through a connecting piece 5, and a double push rod assembly 6 for adjusting the angle of the bracket is arranged between the column 1 and the corresponding inclined beam 3, and adjacent double push rod assemblies 6 are connected by a transmission rod 7, and the double push rod assembly 6 at one end is connected to an external driving device.

With this design, the structure of two main beams 2 and multiple inclined beams 3 connected to each other not only makes the main beam 2 mainly bear the bending moment, but also the inclined beam 3 realizes rotation. This force distribution is more reasonable, which improves the bearing capacity of the bracket. At the same time, the torsion beam has a smaller span and a smaller torque, which reduces the risk of structural deformation, thereby enhancing the stability of the entire bracket and enabling it to better resist external pressure. In addition, there are two main beams supporting the purlins, which reduces the cantilever length, thereby enhancing the stability of the entire bracket and enabling it to better resist external pressure.

In addition, by cooperating with the double push rod assembly 6 and the transmission rod 7, the inclined beam 3 can be accurately adjusted to any angle within the adjustment range, and the angle can be flexibly adjusted according to actual needs, so that the photovoltaic panel can better adapt to different lighting conditions and improve power generation efficiency.

The double push rod assembly 6 includes two push rods 61 arranged in parallel and staggered on both sides of the column 1, and the two push rods 61 have a self-locking function. The telescopic directions of the two push rods 61 are opposite, and the input ends of the two push rods 61 are connected by a linkage rod 62. The telescopic ends of the two push rods 61 are connected to the inclined beam 3 through corresponding swing arm assemblies 63 respectively, and the other ends of the two push rods 61 are connected to the column 1 through an installation assembly 64.

With this design, firstly, the two push rods 61 arranged in parallel and staggered manner on both sides of the column 1 make the structure of the entire bracket more stable, improve the ability to resist external loads, and enhance the stability of the bracket; secondly, the push rods 61 are all equipped with a self-locking function, which can reliably lock the position after adjusting the angle, thereby enhancing safety, so that there is no need to use bolts or pins to lock after each adjustment, and then one person can complete the adjustment with tools, which is simple to operate and saves labor costs; thirdly, through the transmission of the linkage rod 62, the two push rods 61 can work synchronously and accurately to achieve fine adjustment of the bracket angle to meet the needs under different lighting conditions; fourthly, through the connection method of the push rod 61 with the inclined beam 3 and the column 1, the force can be evenly distributed on each component, thus avoiding local stress concentration and extending the service life of the bracket.

The column 1 is provided with a first through hole 8 for the linkage rod 62 to pass through, and the diameter of the first through hole 8 is greater than the diameter of the linkage rod 62 .

Such a design, by setting the diameter of the first through hole 8 to be larger than the diameter of the linkage rod 62, not only creates ample space for the movement of the linkage rod 62, ensuring its smooth movement; it also greatly reduces the friction resistance between the linkage rod 62 and the first through hole 8, making the linkage process smoother; at the same time, it also makes the installation and adjustment of the linkage rod 62 easier.

In the embodiment, the bottom of each of the columns 1 is fixedly connected to a pile foundation 9 .

This design, through the pile foundation 9 deep underground, provides a more solid support for the column 1, which can effectively prevent the column 1 from shaking or tilting, thereby not only improving the ability of the entire structure to resist external forces such as wind and earthquake, but also ensuring the stable installation of the column 1 even in places with poor geological conditions, while reducing structural damage caused by factors such as ground instability, thereby extending the service life of the photovoltaic bracket.

In addition to this embodiment, the column 1 can also be fixed on the ground.

With this design, the column 1 is directly fixed on the ground, which not only makes the installation process convenient and quick, but also reduces the installation cost.

The connecting member 5 includes a support seat fixedly mounted on the top of the column 1, a pin is passed through the support seat, and the support seat is hinged to the inclined beam 3 through the pin.

With this design, the support seat is hinged to the inclined beam 3 through a pin, which not only allows the inclined beam 3 to rotate flexibly relative to the support seat to adapt to different stress conditions; it also helps to maintain a stable connection between the column 1 and the inclined beam 3, and improves the stability of the overall structure; at the same time, the pin connection structure is relatively simple, easy to install and disassemble, and convenient for subsequent maintenance work.

The swing arm assembly 63 includes a mounting rod 631 fixedly mounted on the inclined beam 3 , a connecting seat 632 is fixedly connected to the bottom of the mounting rod 631 , and an output end of the push rod 61 is hinged to the connecting seat 632 .

The mounting assembly 64 includes two mounting seats 641 disposed on both sides of the column 1 , and the two mounting seats 641 are arranged opposite to each other in a staggered manner. The mounting seats 641 and the column 1 are connected together by a plurality of fixing bolts 642 .

The overall structure of the mounting seat 641 is "U"-shaped.

Two mounting positions are formed between the two mounting seats 641 , and the two mounting positions are symmetrically arranged, and the push rod 61 is arranged in the corresponding mounting position.

With this design, firstly, the two "U"-shaped mounting seats 641 are staggered and arranged relative to each other, so that the push rod 61 is more firmly fixed in the mounting position and is not easy to shake; secondly, the symmetrically arranged mounting positions can accommodate push rods 61 of different sizes and shapes; thirdly, the space is reasonably utilized to make the structure of the entire mounting assembly 64 more compact; fourthly, the mounting seat 641 is installed on the column 1 by a plurality of fixing bolts 642. This installation method is simple and quick, and is convenient for later maintenance and adjustment.

Two second through holes 643 are symmetrically formed on the two side walls of the mounting seat 641 , and the two input shafts of the push rod 61 rotate through the corresponding second through holes 643 .

When in use, firstly, the external driving device is started, and then the double push rod assembly 6 at one end of the driving device starts to operate.

At this time, the two push rods 61 in the double push rod assembly 6 are synchronously extended and retracted with the help of the linkage rod 62; because the two push rods 61 have opposite extension and retraction directions, one of the push rods 61 will push the inclined beam 3, while the other will pull the inclined beam 3.

Since the inclined beam 3 is hinged to the column 1 through a connecting assembly, the angle of the inclined beam 3 will change accordingly, thereby driving the position of the main beam 2 to change.

A plurality of purlins 4 are arranged in parallel and at intervals on the main beam 2, which are arranged perpendicular to the main beam 2, and the oblique beam 3 is parallel to the purlin 4. Therefore, the angle of the purlin 4 will also change with the change of the angle of the oblique beam 3. After such adjustment, the photovoltaic bracket can better adapt to different light angles, significantly improve the lighting effect of the photovoltaic panel, and thus improve the efficiency of photovoltaic power generation.

For ordinary technicians in this field, according to the teachings of the present invention, without departing from the principles and spirit of the present invention, changes, modifications, substitutions and variations made to the implementation methods are still within the protection scope of the present invention.
