Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of photovoltaic support, in particular to a solar photovoltaic support. BACKGROUND

[0002] In particular, in recent years, with the increasing number of electric vehicles in China, the consumption of commercial power is also increasing, resulting in a lot of 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 supports are set as tracking photovoltaic supports that can track the angle of sunlight. The most common one is a dual-axis tracking photovoltaic support, that is, the solar panels on the photovoltaic support can be rotated and adjusted in angle under the drive of the driving mechanism around two mutually perpendicular axes, so that the solar panels can rotate to follow the change of the angle of sunlight, thereby improving the photoelectric conversion rate of solar photovoltaic.

[0003] The dual-axis tracking photovoltaic support of the related technology includes a base installed on the ground, a stand connected to the base, a rotating support installed at the upper end of the stand, and a solar panel assembly installed on the rotating support. The photovoltaic support also includes a driving mechanism for adjusting the inclination angle of the solar panel assembly. The driving mechanism generally has two driving mechanisms. One driving mechanism can drive the rotating support to rotate around the first axis, so that the solar panel assembly adjusts the inclination angle in the first direction. The other driving mechanism can drive the solar panel assembly to rotate around the second axis, so that the solar panel assembly adjusts the inclination angle in the second direction. The rotation axis of the first axis is perpendicular to the rotation axis of the second axis, such as the photovoltaic support in the Chinese patent application with publication number CN116795145A.

[0004] In order to prevent damage caused by being blown down by strong winds, the stand of the photovoltaic support of the related technology is set as a liftable type, that is, the solar panel assembly is lowered to a lower height from the ground during strong winds to improve the wind resistance. For example, the photovoltaic support in the Chinese patent application with publication number CN117318591A, the lifting stand includes a hollow fixed rod fixedly connected to the ground, a movable rod slidingly fitted on the fixed rod, and a driving mechanism. The driving mechanism is an electric push rod. The upper end of the electric push rod is connected to the movable rod, and the lower end of the electric push rod is connected to the fixed rod. During strong winds, the electric push rod can drive the movable rod to slide downward to lower the height of the photovoltaic assembly.

[0005] The solar photovoltaic support system of this technology has the following defects in actual use: In order to facilitate the lifting and assembly of the lifting column, there is a certain gap between the fixed rod and the movable rod of the lifting column. Therefore, when the photovoltaic support system is blown by strong winds, the movable rod will sway or tilt relative to the fixed rod. The force borne by the movable rod is transmitted to the ground through the drive mechanism connecting the movable rod and the fixed rod. This not only easily causes the drive mechanism to be damaged by stress, but also makes the wind resistance of the photovoltaic support system weak. Utility Model Content

[0043] The present application will be further described in detail below in combination with the drawings and specific embodiments.

[0044] Referring to Figures 1-9 The present application discloses a solar photovoltaic support, which comprises a base 6, a lifting assembly 2, a driving assembly 3 and a photovoltaic assembly 1. The base 6 is fixedly connected with the ground through bolts, rivets and other fasteners. The lower end of the lifting assembly 2 is connected with the base 6, and the upper end of the lifting assembly 2 is connected with the photovoltaic assembly 1. The lifting assembly 2 is used for adjusting the height of the photovoltaic assembly 1. The photovoltaic assembly 1 comprises a photovoltaic mounting frame 100 and a plurality of solar power panels 101 fixedly connected with the photovoltaic mounting frame 100. The solar photovoltaic support can not only generate electricity through the solar power panels 101 of the photovoltaic assembly 1, but also can be used as a sunshade carport.

[0045] Referring to Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, the lifting assembly 2 comprises a first rod 200 fixedly connected with the base 6 and a second rod 201 axially sliding relative to the first rod 200, the second rod 201 being connected with the photovoltaic assembly 1; the second rod 201 axially extends and retracts relative to the first rod 200 to thereby adjust the height of the photovoltaic assembly 1; the driving assembly 3 comprises a housing 300, a driving rod 301 connected in the housing 300 and axially extending and retracting relative to the housing 300, and a driving mechanism drivingly connected with the driving rod 301 for driving the driving rod 301 to move; the housing 300 of the driving assembly 3 is connected with the first rod 200, and the free end of the driving rod 301 of the driving assembly 3 is universally connected with the second rod 201. The driving mechanism of the driving assembly 3 can drive the driving rod 301 to extend and retract, thereby driving the second rod 201 to linearly move relative to the first rod 200.

[0046] In the above embodiment, the solar photovoltaic support drives the lifting assembly 2 to lift and thereby adjust the height of the photovoltaic assembly 1 through the driving assembly 3, so that when installing the photovoltaic support, the second rod 201 of the lifting assembly 2 is lowered to the lowest height, and after the photovoltaic assembly 1 is installed, the driving assembly 3 drives the second rod 201 of the lifting assembly 2 to be raised to the required height, thereby making the whole installation process simple and safe. In addition, the free end of the driving rod 301 of the driving assembly 3 for driving and supporting the second rod 201 is universally connected with the second rod 201, so that when the second rod 201 or the photovoltaic assembly 1 is subjected to wind force in a non-vertical direction, the photovoltaic assembly 1 together with the second rod 201 will rotate at a certain angle relative to the driving rod 301 of the driving assembly 3, avoiding the transmission of the wind force to the driving assembly 3, thereby weakening the wind force borne by the driving assembly 3, preventing the driving assembly 3 from being damaged, and improving the wind resistance of the solar photovoltaic support. Furthermore, in windy weather, the height of the photovoltaic assembly 1 can be lowered through the driving assembly 3 to avoid the photovoltaic assembly 1 from being shaken by the wind and to avoid the photovoltaic support from being damaged.

[0047] In the foregoing embodiment, the second rod 201 axially slides relative to the first rod 200, which includes the following several embodiments: first, the second rod 201 is located outside the first rod 200, and the first rod 200 and the second rod 201 are arranged in parallel; second, the first rod 200 and the second rod 201 are both hollow, and the second rod 201 is sleeved outside the first rod 200; third, the first rod 200 and the second rod 201 are both hollow, and the second rod 201 is sleeved inside the first rod 200.

[0048] Specifically in the present embodiment, referring to Figure 2 and Figure 4As shown, the first rod member 200 and the second rod member 201 are both hollow rod members, and the second rod member 201 is slidingly sleeved outside the first rod member 200; the driving assembly 3 is arranged in the first rod member 200 in the vertical direction, the lower end of the housing 300 of the driving assembly 3 is fixedly connected with the lower part of the first rod member 200 by means of bolts, and the free end of the driving rod 301 of the driving assembly 3 is universally connected with the second rod member 201.

[0049] It can be understood that, in order to facilitate the axial sliding of the second rod member 201 relative to the first rod member 200, there is a sliding gap between the inner wall of the second rod member 201 and the outer peripheral wall of the first rod member 200, and when the second rod member 201 is subjected to a force in a non-vertical direction, it will be inclined in the vertical direction; the inclination of the second rod member 201 after being subjected to the force will cause the driving rod 301 of the driving assembly 3 to be inclined, so that the driving rod 301 of the driving assembly 3 bears a force in a non-vertical direction; in the related art, although the free end of the driving rod 301 of the driving assembly 3 can be rotatably connected with the second rod member 201 by means of a rotating pin, the rotation direction between the driving rod 301 and the second rod member 201 is fixed or only has one rotation direction, and when the second rod member 201 is subjected to a force in a non-vertical direction, especially under the blowing force of strong wind, the direction of the force is not fixed and variable, so that the photovoltaic support with only one rotation direction or a fixed rotation direction between the driving rod 301 and the second rod member 201 will still and inevitably cause the driving rod 301 to bear a large torsion force, resulting in damage to the driving rod 301 and affecting the lifting of the lifting assembly 2.

[0050] In the embodiment, the free end of the driving rod 301 of the driving assembly 3 is universally connected with the upper end of the second rod member 201 by means of a universal joint structure, so that no matter the direction of the force applied to the second rod member 201 in a non-vertical direction, the relative rotation between the second rod member 201 and the driving rod 301 of the driving assembly 3 will occur when the second rod member 201 is inclined in the vertical direction, so as to avoid transmitting the force to the driving assembly 3 and protecting the driving assembly 3.

[0051] Further in the embodiment, referring to Figure 5 and Figure 6As shown, the universal joint structure between the free end of the driving rod 301 and the upper end of the second rod 201 comprises a ball seat 305 connected to the free end of the driving rod 301 and a main shaft 206 connected to the second rod 201, the main shaft 206 passes through the ball seat 305, and the main shaft 206 is connected with a ball 306 which is connected with the ball seat 305 in a universal manner; thus when the second rod 201 bears a force in a non-vertical direction, the second rod 201 drives the main shaft 206 and the ball 306 to rotate around the ball seat 305 as a fulcrum, so as to avoid transmitting the force to the driving rod 301. Of course, when the driving rod 301 is driven to extend or retract by the driving mechanism, the second rod 201 can be driven to ascend or descend.

[0052] In other embodiments, the universal joint structure can also be as follows, as shown in Figure 10 and Figure 11 , the universal joint structure comprises a spherical body 307 connected to the free end of the driving rod 301 and a spherical seat 308 connected to the second rod 201, the spherical body 307 is connected with the spherical seat 308 in a universal manner, in Figure 10 , the spherical body 307 is fixedly connected to the free end of the driving rod 301, and the spherical seat 308 is fixedly connected to the top of the second rod 201; in Figure 11 , the spherical body 307 is integrally formed with the free end of the driving rod 301, or the spherical body 307 is integrally connected with a connecting head which is fixedly connected with the free end of the driving rod 301.

[0053] In other embodiments, as shown in Figure 12 and Figure 13 , the universal joint structure comprises a first connecting head 309 which is connected with the second rod 201 in a rotating manner, the first connecting head 309 is connected with a second connecting head 310 in a rotating manner, and the second connecting head 310 is connected with the free end of the driving rod 301 in a rotating manner through a bearing 311, and the rotating direction of the first connecting head 309 is perpendicular to the rotating direction of the second connecting head 310. The universal joint structure is also called a universal connector, the second connecting head 310 can rotate relative to the first connecting head 309, and the second connecting head 310 can rotate along the circumference of the driving rod 301 through the bearing 311; thus when the second rod 201 bears a force in a non-vertical direction, the second rod 201 can rotate relative to the driving rod 301, so as to avoid transmitting the force to the driving rod 301.

[0054] In the above embodiments, the driving mechanism is in transmission connection with the driving rod 301 for driving the driving rod 301 to move, and the driving mechanism can be an electric drive or a manual drive; the electric drive is to drive the driving rod 301 to extend or retract by a driving motor 302, and the manual drive can drive the driving rod 301 to extend or retract by a crank handle. Specifically, in the present embodiment, as shown in Figure 4 , Figure 5 and Figure 9As shown, the driving mechanism is a driving motor 302, and a screw nut assembly is connected with the driving motor 302 in the shell 300, the screw nut assembly is connected with the driving rod 301, and is used for driving the driving rod 301 to axially extend and retract relative to the shell 300. Specifically, the screw nut assembly comprises a screw rod 303 and a transmission nut 304, the driving motor 302 is in transmission connection with the screw rod 303 through a transmission gear or a worm gear, and is used for driving the screw rod 303 to rotate; the transmission nut 304 is threadedly connected on the screw rod 303, is circumferentially limited in the shell 300, and is slidingly fitted in the shell 300; the transmission nut 304 is fixedly connected with the driving rod 301, the driving motor 302 drives the screw rod to rotate, so that the transmission nut 304 extends and retracts together with the driving rod 301 to drive the second rod 201 to lift and lower.

[0055] In the embodiment, as shown in Figure 1 、 Figure 3 and Figure 5 , the top of the second rod 201 is rotatably connected with a rotating support 4, and the second rod 201 is connected with a first driving member 5 for driving the rotating support 4 to rotate in a first direction; the rotating support 4 is rotatably connected with the photovoltaic module 1, and the rotating support 4 is connected with a second driving member 500 for driving the photovoltaic module 1 to rotate in a second direction, wherein the first direction and the second direction are different. In this way, the photovoltaic module 1 can be inclined at any angle under the driving cooperation of the first driving member 5 and the second driving member 500, so as to adapt to the change of the sunlight irradiation angle and improve the solar energy conversion rate of the photovoltaic module 1.

[0056] For example, as shown in Figure 3 , the first driving member 5 and the second driving member 500 are both electric push rods; the solar photovoltaic support further comprises a controller, which is electrically connected with the first driving member 5, the second driving member 500 and the driving motor 302 of the driving assembly 3. The lifting of the lifting assembly 2 can be controlled through the controller, and the first driving member 5 and the second driving member 500 are controlled to act so that the photovoltaic module 1 can adapt to the change of the sunlight irradiation angle and improve the solar energy conversion rate of the photovoltaic module 1.

[0057] In the above embodiment, the rotating support 4 is rotatably connected with the top of the second rod 201 through a rotating shaft 400, the first end of the first driving member 5 is hinged to the second rod 201, and the other end is connected with the rotating support 4; the rotating support 4 is rotatably connected with a cross beam 402 through a rotating sleeve 401, the cross beam 402 is fixedly connected with the photovoltaic mounting rack 100, one end of the second driving member 500 is hinged to the photovoltaic mounting rack 100, and the other end is connected with the rotating support 4; the rotating direction of the rotating support 4 is perpendicular to the rotating direction of the photovoltaic mounting rack 100, that is, the first direction and the second direction are perpendicular. That is, the solar photovoltaic support of the embodiment is a double-axis photovoltaic support.

[0058] It is understandable that the solar photovoltaic support of the embodiment can be configured with a GPS control system, which controls the motion state of the first driving member and the second driving member according to astronomical algorithm, so as to control the rotation angle of the photovoltaic assembly, greatly improving the power generation efficiency of the photovoltaic; similarly, a wind sensor can be configured, when encountering strong wind, the sensor senses the strong wind, and the information is transmitted to the controller, which controls the tracking of the first driving member and the second driving member, drives the photovoltaic assembly to be horizontal, and controls the driving assembly in the lifting assembly, so as to greatly increase the wind resistance; when encountering heavy snow and other bad weather, the controller automatically controls the lifting assembly to shrink to the lowest state, thereby greatly increasing the compression resistance.

[0059] Further in the embodiment, as shown in Figure 4 、 Figure 5 and Figure 6 , the first rod member 200 and the second rod member 201 are both hollow rod members, and the second rod member 201 is slidingly sleeved on the first rod member 200; a force transmission plate 203 is arranged between the first rod member 200 and the second rod member 201 in the circumferential direction, for transmitting the non-vertical force to the ground through the force transmission plate 203 and the first rod member 200 when the second rod member 201 is subjected to a non-vertical force. It can be understood that when the photovoltaic assembly 1 and the second rod member 201 bear their own gravity or vertical pressure, the force is vertically downward from the second rod member 201, the driving assembly 3 and the first rod member 200 to the ground; when the photovoltaic assembly 1 and the second rod member 201 bear a non-vertical force, the second rod member 201 tilts, the second rod member 201 rotates relative to the driving assembly 3, and the non-vertical force on the second rod member 201 is transmitted to the first rod member 200 through the force transmission plate 203, and then transmitted to the ground by the first rod member 200. Therefore, the arrangement of the force transmission plate 203 not only compensates for the gap between the second rod member 201 and the first rod member 200, but also transmits the non-vertical force on the second rod member 201 to the first rod member 200 without passing through the driving assembly 3, which not only makes the structure of the photovoltaic support stable and strong, but also weakens the wind resistance of the driving assembly 3, prevents the driving assembly 3 from being damaged, and improves the wind resistance of the solar photovoltaic support.

[0060] For example, as shown in Figure 4 and Figure 6As shown, the first rod member 200 and the second rod member 201 are both hollow quadrangular tubes, the second rod member 201 is sleeved on the outside of the first rod member 200, a plurality of force transmission plates 203 are connected on the outer circumferential wall of the upper end of the first rod member 200 in the circumferential direction, and the force transmission plates 203 are in contact with the inner wall of the second rod member 201 or in contact with the inner wall of the second rod member 201 when the second rod member 201 is tilted by a non-vertical force. The force transmission plates 203 of the present embodiment are fixedly connected to the outer circumferential wall of the upper end of the first rod member 200 by screws, and the force transmission plates 203 are plates with a certain thickness, which can transmit force to the first rod member 200 when the second rod member 201 is subjected to a non-vertical force.

[0061] In some embodiments, the force transmission plates can also be connected on the inner wall of the second rod member in the circumferential direction, and the force transmission plates are in contact with the outer wall of the first rod member 200 or in contact with the outer wall of the first rod member when the second rod member is tilted by a non-vertical force.

[0062] In other embodiments, if the first rod member and the second rod member are both hollow circular tubes, the force transmission plates can be one and arranged in a ring shape.

[0063] In order to further improve the structural strength and stability of the photovoltaic support and enhance the wind resistance, as shown in Figure 4 , Figure 7 and Figure 8 , a plurality of friction members 204 are connected on the end of the second rod member 201 close to the base 6 in the circumferential direction, the friction members 204 are arranged in the sliding gap between the second rod member 201 and the first rod member 200, and the friction members 204 are in sliding contact with the first rod member 200. The arrangement of the friction members 204 can fill the gap between the second rod member 201 and the first rod member 200, further prevent the second rod member 201 from shaking relative to the first rod member 200, and the friction members 204 can be flexible friction plates made of rubber or plastic, which can make the sliding more stable when the second rod member 201 slides relative to the first rod member 200.

[0064] In some embodiments, as shown in Figure 8As shown, the second rod member 201 is threadedly connected with an adjusting rod 205, the inner end of the adjusting rod 205 is connected with the friction member 204, and the outer end of the adjusting rod 205 is exposed outside the second rod member 201 and forms a driving end. The adjusting rod 205 is used to adjust the gap between the friction member 204 and the first rod member 200. That is, the gap between the friction member 204 and the first rod member 200 is adjustable, so that not only the smoothness of the sliding of the second rod member 201 relative to the first rod member 200 can be ensured, but also in windy weather, the driving end of the adjusting rod 205 can be rotated to press the friction member 204 against the first rod member 200, so that the sliding gap between the second rod member 201 and the first rod member 200 can be eliminated, the shaking of the second rod member 201 relative to the first rod member 200 can be prevented, and thus the mechanical strength, the structural stability and the wind resistance of the lifting assembly 2 can be improved.

[0065] In some embodiments, in order to further improve the structural strength of the lifting assembly 2 and improve the wind resistance of the photovoltaic support, referring to Figure 4 and Figure 7 As shown, the outer side wall of the second rod member 201 outside the friction member 204 is fixedly connected with a reinforcing sleeve 202, and the outer end of the adjusting rod 205 is exposed outside the reinforcing sleeve 202. The reinforcing sleeve 202 is a metal sleeve made of metal, which is sleeved on the outer side wall of the second rod member 201 and located outside the friction member 204, that is, sleeved on the outer side wall of the lower end of the second rod member 201, so as to improve the mechanical strength of the lower end of the second rod member 201 and make the structural strength of the friction member 204 higher when it is adjusted to press the first rod member 200, and the wind resistance is stronger.
