Moreover, the terms "comprises," "comprising," or any other variation thereof, are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements does not include only those elements but may include other elements not expressly listed or inherent to such process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising … …" does not exclude the presence of other like elements in a process, method, article or apparatus that comprises the element. If not conflicting, the embodiments of the present utility model and the features of the embodiments may be combined with each other, which are all within the protection scope of the present utility model.

First, the terms involved in the present utility model will be explained:

photovoltaic power generation: and converting solar energy into electric energy by utilizing the photovoltaic effect. The solar energy power generation technology is a renewable energy power generation technology, solar radiation is converted into direct current through a photovoltaic cell, and then the direct current is converted into alternating current through an inverter, so that the alternating current is supplied to families, industries or power grids for use.

Currently, photovoltaic panels are installed in open air conditions and are typically required to be oriented at an incline to the sun, depending on the local latitude and longitude and sunlight conditions. For example, referring to fig. 1, the mounting frame 20 is fixedly connected to the third supporting mechanism 10, and the mounting frame 20 is disposed obliquely with respect to the third supporting mechanism 10, and the third photovoltaic panel 30 is mounted on the mounting frame 20. The installation mode maximally utilizes the irradiation of sunlight, and improves the efficiency of the photovoltaic power generation system. Under this configuration, sunlight irradiates onto the photovoltaic panel, electricity is generated by the photoelectric effect, and then transmitted to the inverter through the cable for conversion, and finally ac power is obtained to be supplied to the home and industrial electricity.

However, photovoltaic panels present challenges in certain areas, particularly in the harsh environments of deserts and the like. Climate conditions in desert areas are often accompanied by strong winds and sand storms, which can have a wind load on the photovoltaic power generation device. When strong winds strike the photovoltaic panel, significant compressive forces and forces may be generated, which may result in collapse and damage to the photovoltaic panel if the photovoltaic panel is not securely fastened and supported. This not only affects the stable operation of the photovoltaic power generation system, but can also result in high maintenance and replacement costs.

With reference to fig. 2 and 3, an embodiment of the present utility model provides a photovoltaic bracket, including:

a first support mechanism 100;

the fixing frame 200 is fixedly connected to the first supporting mechanism 100, the fixing frame 200 is obliquely arranged relative to the first supporting mechanism 100, and the fixing frame 200 is used for installing a photovoltaic panel;

the movable frame 300 has a deployed state and a supported state: in the supporting state, the telescopic supporting piece 500 compresses and drives the movable frame 300 to rotate relative to the fixed frame 200, so that the movable frame 300 is abutted against the second supporting mechanism 400, and the fixed frame 200 and the movable frame 300 form an inverted V-shaped structure; in the unfolded state, the telescopic support 500 stretches and drives the movable frame 300 to separate from the second support mechanism 400, so that the fixed frame 200 and the movable frame 300 are located on the same plane.

In some embodiments, one of the movable frame 300 and the fixed frame 200 is provided with a rotation shaft, and the other is rotatably connected thereto through the rotation shaft.

In other embodiments, the movable frame 300 and the fixed frame 200 are hinged to achieve a rotational connection of the movable frame 300 and the fixed frame 200.

The rotational connection mode of the movable frame 300 and the fixed frame 200 is not limited to the above two modes, and can be adjusted according to specific requirements, so long as the rotational connection of the two can be realized.

The photovoltaic bracket provided by the utility model is provided with the fixed frame 200 fixedly arranged, the movable frame 300 movably connected with the fixed frame 200 and the telescopic support piece 500 connected with the movable frame 300, and the movable frame is switched between the unfolding state and the supporting state by compressing and stretching the telescopic support piece 500, so that solar energy can be fully utilized in a conventional environment, and wind power can be resisted in a severe environment.

When in a supporting state, please refer to fig. 2, the telescopic supporting piece 500 compresses, the movable frame 300 is abutted with the second supporting mechanism 400, the fixed frame 200 and the movable frame 300 form an inverted V-shaped structure, the wind load applied to the inverted V-shaped structure is smaller, the supporting area of the bottom of the support is larger due to the inverted V-shaped structure, the wind-proof effect is good, the effect of the wind load applied to the photovoltaic panel is smaller even in areas with larger wind force such as deserts, and the supporting performance of the photovoltaic support structure is good, and the photovoltaic panel on the photovoltaic support is not easy to collapse.

In the unfolded state, referring to fig. 3, the telescopic support 500 is extended, and the fixed frame 200 and the movable frame 300 are positioned in the same plane, in which the photovoltaic panel can be completely unfolded, and solar energy can be collected to the maximum extent.

Referring to fig. 2 and 3, the photovoltaic bracket has a first supporting mechanism 100 and a second supporting mechanism 400, and the first supporting mechanism 100 can better set the fixing frame 200 to have a certain inclination angle, so that the fixing frame 200 can absorb solar energy to the greatest extent; in the supporting state of the movable frame, the second supporting mechanism 400 provides additional support for the movable frame 300, so that the supporting performance of the photovoltaic bracket is good, the structure is stable, wind power can be well resisted, a good installation environment is provided for the photovoltaic panel, and the normal operation of the photovoltaic panel is ensured.

In particular, the movable frame provides different support modes for the photovoltaic panel in the unfolded state and the support state.

When the photovoltaic bracket is in the unfolded state, referring to fig. 3, the telescopic support 500 is extended, and the movable frame 300 is separated from the second support mechanism 400, so that the fixed frame 200 and the movable frame 300 are located on the same plane. In this state, the photovoltaic panel can be fully unfolded, covering a relatively large area. The larger the surface area of the photovoltaic panel, the more solar radiation energy is received. Under good illumination conditions, the photovoltaic panel can more fully utilize solar energy to convert sunlight into electric energy. Therefore, the fixed frame 200 and the movable frame 300 are positioned on the same plane, so that solar energy can be collected to the greatest extent and the power generation efficiency of the photovoltaic power generation system can be optimized.

In the supporting state, referring to fig. 2, the movable frame 300 abuts against the second supporting mechanism 400, and the telescopic supporting member 500 is compressed, so that the fixed frame 200 and the movable frame 300 form an inverted V-shaped structure. By the design, when the photovoltaic bracket is impacted by strong wind and sand, the photovoltaic bracket can resist the effect of wind better, the stability and wind resistance of the photovoltaic panel are enhanced, and the collapse of the photovoltaic panel is effectively avoided. The design of the inverted V-shaped structure increases the stability and wind resistance of the stent mainly for several reasons:

firstly, the inverted V-shaped structure enables the whole bracket to better disperse wind force action when facing wind force impact by dispersing and arranging supporting points on two sides of the bracket. Therefore, the support is more uniformly stressed, the situation of overlarge local stress can not occur, and the possibility of deformation and damage of the support is reduced.

Second, the inverted V-shaped configuration allows for a greater support area at the bottom of the bracket. Thus, under the action of facing wind force, the bottom of the bracket can better resist the horizontal force blown by the wind, and the stability of the bracket is increased. In contrast, the fixed frame 200 and the movable frame 300 are located on the same plane, and under the action of wind force, the support bottom support area is smaller, and the horizontal force born by the support is relatively concentrated, so that the support is easy to topple over and damage.

The inverted V-shaped structure can better block the erosion of wind and sand through the design of the inclined plane. In areas with serious wind and sand, such as deserts, the erosion of wind and sand to the support and the photovoltaic panel can cause the damage of the photovoltaic power generation system. The inverted V-shaped structure reduces the direct impact of wind and sand on the bracket through the arrangement of the inclined plane, and protects the stable operation of the photovoltaic power generation system.

In addition, the inverted V-shaped structure reduces the contact area of the photovoltaic panel provided on the photovoltaic bracket with wind, compared to the structure in which the fixed frame 200 and the movable frame 300 are coplanar, thereby reducing wind resistance. When wind force acts on the photovoltaic board, the horizontal force that produces because of the windage can be reduced to the reverse V-arrangement structure of support, has reduced the wind-force impact that whole support system received.

In some embodiments, the telescoping support 500 compresses or expands and rotates the movable frame 300 relative to the fixed frame 200 such that the movable frame also has a horizontal state (not shown), a support transition state (not shown), and an expansion transition state (not shown): in the horizontal state, the movable frame 300 is parallel to the horizontal plane; in the process that the movable frame 300 rotates from a position parallel to the horizontal plane to a position abutting against the second supporting mechanism 400, the form of the movable frame changes from the horizontal state to the supporting state, and the form between the horizontal state and the supporting state is called a supporting transition state of the movable frame; in the process that the movable frame 300 rotates from a position parallel to the horizontal plane to a position where the fixed frame 200 and the movable frame 300 are positioned on the same plane, the form of the movable frame changes from the horizontal state to the unfolded state, and the form between the horizontal state and the unfolded state is called an unfolded transition state of the movable frame.

In the support transition state, the telescopic support 500 is contracted, the movable frame 300 is separated from the second support mechanism 400, and the fixed frame 200 and the movable frame 300 are inclined toward each other, that is, a support space is formed between the fixed frame 200 and the movable frame 300, which is gradually widened from top to bottom, and the first support mechanism 100, the second support mechanism 400 and the telescopic support 500 are all located in the support space. In this case, the photovoltaic support also has a certain windproof effect.

In the unfolded transition state, the movable frame 300 has an inclination angle consistent with the inclination direction of the fixed frame 200, in which case solar energy can be collected at different angles.

To facilitate understanding of the structure of the photovoltaic bracket, the photovoltaic bracket will now be further described in connection with the structure of the first support mechanism 100, the fixed frame 200, the movable frame 300, the second support mechanism 400, and the telescopic support 500, as follows:

Specifically, first, the height of the telescoping support 500 is greater than the height of the second support mechanism 400, providing additional support height for the photovoltaic bracket. The height of the telescoping support 500 enables the photovoltaic panel to tilt toward the sun when the photovoltaic stand is deployed. The inclined arrangement is favorable for receiving sunlight to the greatest extent, and improves the solar energy utilization efficiency of the photovoltaic panel. Through optimizing inclination, photovoltaic power generation system can collect solar energy more effectively, improves generating efficiency, increases electric power output.

Second, the telescoping support 500 is located between the first support mechanism 100 and the second support mechanism 400, providing enhanced support for the stability and wind resistance of the photovoltaic bracket. In the supported state, the telescopic support 500 maintains a high height, forms a support with the second support mechanism 400, and forms an inverted V-shaped structure. The structure can increase the support area of the bottom of the bracket and reduce the possibility of toppling of the bracket due to wind impact. Meanwhile, the high telescopic support 500 can also reduce the resistance of wind power, improve the stability of the photovoltaic bracket when the photovoltaic bracket is impacted by strong wind and sand, and effectively prevent the collapse and damage of the photovoltaic panel.

In some embodiments, referring to fig. 2 and 3, first support mechanism 100 includes at least one first upright 110 and at least one second upright 120, second upright 120 being positioned between first upright 110 and telescoping support 500, and second upright 120 having a height that is greater than a height of first upright 110. The height of the second upright 120 is higher than that of the first upright 110, increasing the support area of the bottom of the support, thereby enhancing the stability of the photovoltaic support in the face of wind impact. The second upright 120 is located between the first upright 110 and the telescopic support 500, and helps to disperse the stress of the support, reduce the possibility of local overstressing of the support, improve the structural stability of the support, and prevent collapse and damage of the photovoltaic panel. The at least one second upright 120 and the at least one first upright 110 means that the number of first uprights 110 and second uprights 120 can be adjusted according to specific requirements. This flexibility enables the photovoltaic rack to accommodate different site conditions and installation requirements.

In some embodiments, telescoping support 500 is fixedly coupled to second upright 120 (not shown) or to the ground, such as, but not limited to, the ground.

In the present utility model, referring to fig. 2 and 3, the telescopic support 500 is slidably connected to the movable frame 300, so that the telescopic support 500 moves within a predetermined stroke relative to the movable frame 300 during rotation of the movable frame 300.

The setting position of the telescopic support 500 is relatively fixed, one end of the movable frame 300 is rotationally connected with the fixed frame 200, the position of the fixed frame 200 is unchanged, one end of the movable frame 300 connected with the fixed frame 200 is unchanged, the telescopic support 500 is compressed or stretched along the axial direction of the movable frame 300 in the rotating process, the length of the telescopic support 500 is changed, the sliding connection position of the telescopic support 500 and the movable frame 300 is also changed along with the change of the telescopic support 500, and the preset stroke is the position change range of the connection point of the telescopic support 500 and the movable frame 300 and is used for limiting the rotating angle range of the movable frame 300.

In some embodiments, referring to fig. 2 to 5, the telescopic support 500 has a telescopic end 510, a sliding rod 520 is disposed on the telescopic end 510, a sliding slot 310 is disposed on a side surface of the movable frame 300, and the sliding rod 520 is slidably connected with the sliding slot 310. In this embodiment, the sliding rod 520 is perpendicular to the sliding slot 310 and can slide along the sliding slot 310, and this design allows the telescopic support 500 to slide relative to the movable frame 300 during the rotation of the movable frame 300. When the angle of the movable frame 300 needs to be adjusted to optimize the solar energy collection efficiency or realize the wind-proof function thereof, the sliding rod 520 can slide in the sliding groove 310 by adjusting the state of the telescopic support 500, thereby pushing the movable frame 300 to realize the rotation. In addition, the design is simpler, the materials are saved, and the slide way is only needed to be formed by opening holes in the bottom of the angle steel.

Further, the number of the telescopic supporting members 500 can be two, the telescopic supporting members are located at two sides of the movable frame 300, the sliding grooves 310 are formed in two sides of the movable frame 300, the sliding rods 520 at two sides are matched with the sliding grooves 310, and the supporting performance of the movable frame 300 is good.

The number of the telescopic supporting members 500 is not limited by the above two ways, and can be adjusted according to the requirements.

In other embodiments, a slider (not shown) is provided on the telescopic end 510 of the telescopic support 500, and a sliding rail (not shown) is provided on the movable frame 300, where the slider is slidably connected to the sliding rail. In this embodiment, the sliding rail is disposed on the movable frame 300 along the inclined direction of the movable frame 300, so that the telescopic support 500 can drive the movable frame 300 to rotate.

The sliding rail may be a rail mounted on the movable frame, or may be a rail opened on the movable frame. The utility model is not limited in this regard and can be adjusted according to requirements.

It should be noted that the sliding rail may be disposed in the middle of the bottom surface of the movable frame, or may be disposed on a side surface of the movable frame. When the slide rail sets up in the middle part of movable frame bottom surface, the telescopic support piece is in the middle part of bottom surface to the supporting position of movable frame, and the supporting performance is better. When the slide rail sets up the side at the movable frame, in order to guarantee the better supporting property of flexible support piece, can all set up the slide rail in the both sides of movable frame, realize two point support, the supporting property is better.
