[0002] Photovoltaic supports are deployed in the wild environment. If a shed-type support structure is adopted, on the one hand, as the sun angle changes, it is difficult to adjust the pitch angle of the photovoltaic panel accordingly. In addition, the shed-type support has many columns and a large span. In the piling link before installation, the pile parts of multiple columns need to be leveled in cooperation, which is difficult to construct in the wild environment and the construction period is relatively long. Summary of the Invention

[0003] In order to solve the problems existing in the above-mentioned prior art, the present invention provides an integrated adjustable photovoltaic support and an operation method thereof, which shorten the construction time, reduce the construction difficulty and improve the deployment efficiency by integrating the columns of the support on one support.

[0004] The specific technical solution adopted by the present invention is as follows:

[0005] An integrated adjustable photovoltaic support, the support is arranged on a pile body, and includes a base, a support assembly and a photovoltaic frame body erected on the base by means of the support assembly. The photovoltaic frame body is used for laying photovoltaic panels. The photovoltaic frame body is in a rectangular frame structure. The support assembly includes a first support rod, a second support rod hinged to the photovoltaic frame body, and an umbrella-shaped support fixedly connected to the photovoltaic frame body. The umbrella-shaped support includes a main umbrella bone and auxiliary umbrella bones. The main umbrella bone is fixedly connected to the photovoltaic frame body. There are multiple groups of auxiliary umbrella bones arranged around the main umbrella bone. The auxiliary umbrella bones are connected between the overhanging end of the main umbrella bone and the photovoltaic frame body. An expansion rod is further arranged between the overhanging end of the main umbrella bone and the base. The fixed point between the main umbrella bone and the photovoltaic frame body is arranged in a dislocation manner with the hinge axes of the first support rod and the second support rod and the photovoltaic frame body. The umbrella-shaped support enables the photovoltaic frame body to have a swinging freedom degree in the pitch direction by the push of the expansion rod.

[0006] The umbrella-shaped support further includes a reinforcing umbrella bone. One end of the reinforcing umbrella bone is connected to the overhanging end of the main umbrella bone, and the other end is connected to the upper cross beam or the lower cross beam in the swinging direction of the photovoltaic frame body.

[0007] A mask box is arranged on the base. The expansion rod is an electric expansion rod arranged in the mask box. The telescopic end of the electric expansion rod extends outside the mask box and is hinged to the overhanging end of the main umbrella bone. The fixed end of the electric expansion rod is hinged inside the mask box.

[0008] Photovoltaic guide rails for laying photovoltaic panels are further erected on the photovoltaic frame body. Two photovoltaic guide rails are in a group and multiple groups are arranged in parallel on the photovoltaic frame body.

[0009] A cleaning mechanism is further provided on the photovoltaic guide rail. The cleaning mechanism includes a cleaning vehicle and a rail-changing device. A roller brush driven by a motor is provided on the cleaning vehicle. Traveling wheels are provided on both sides of the cleaning vehicle. The traveling wheels and the cleaning vehicle are arranged in a C-shaped structure to surround the photovoltaic guide rail and the photovoltaic panel. The cross-section of the photovoltaic guide rail is a C-shaped groove structure. The traveling wheels are inserted into the groove structure of the photovoltaic guide rail. The cleaning vehicle has the freedom to move up and down along the photovoltaic guide rail by means of the traveling wheels.

[0010] The rail-changing device includes a fixing frame provided at the end of the photovoltaic guide rail. A conveyor belt is provided on the fixing frame. A carrier vehicle is provided on the conveyor belt. The conveyor belt has the freedom to reciprocate between adjacent groups of photovoltaic guide rails by means of a rail-changing motor provided on the fixing frame. The carrier vehicle is fixed on the belt surface of the conveyor belt. A rail-changing guide rail is provided on the carrier vehicle. The cross-section of the rail-changing guide rail is the same as that of the photovoltaic guide rail and is aligned with the photovoltaic guide rail by means of the movement of the conveyor belt.

[0011] The photovoltaic panels laid on the same group of photovoltaic guide rails are arranged in a row and spaced at equal intervals.

[0012] The operation method of the photovoltaic support described in this application includes the following construction steps:

[0013] S1. After the ground at the installation site is leveled, pile bodies are constructed according to the designed positions.

[0014] S2. After the photovoltaic support is transported to the site, the base, the support assembly and the photovoltaic frame body are assembled on the ground to form a complete empty frame body.

[0015] S3. Subsequently, the whole empty frame body is hoisted onto the pile bodies, and the base is fixed by the bolts reserved on the pile bodies to complete the installation of the empty frame body.

[0016] S4. Adjust the telescopic rod to place the photovoltaic frame body in a horizontal state, install the photovoltaic guide rail and lay the photovoltaic panels on the photovoltaic guide rail, and tie the photovoltaic panel lines to the back side of the photovoltaic guide rail to complete the laying of the photovoltaic panels.

[0017] The beneficial effects of the present invention are as follows:

[0018] Through the integrated design, a disc-shaped base is adopted, and the first and second support rods are diverged in a shape of an eight-character to support the photovoltaic frame body, reducing the number of columns. Only one column is required during installation, greatly shortening the installation process and improving the deployment efficiency.

[0019] Reinforcing ribs are provided to make full use of the effective length of the main ribs, so that the main ribs, the secondary ribs and the reinforcing ribs form a stable triangular structure, increasing the overall rigidity and reducing the overall tremor amplitude of the support during the operation of the cleaning mechanism.

[0020] An electric telescopic rod is installed in the mask box, which can follow the change of the sun's angle. The controller controls the telescopic movement of the electric telescopic rod according to the preset program to realize the adjustment of the photovoltaic bracket.

[0021] The cleaning vehicle is clamped in the groove of the photovoltaic track by means of walking wheels. The roller brush rotates to clean the dirt on the photovoltaic panel, and the transmission design of the walking wheels improves the adhesion to the photovoltaic guide rail, avoiding slipping and realizing the stable advancement and retreat of the cleaning vehicle.

[0022] The rail changing device enables the cleaning vehicle to move between adjacent groups of photovoltaic guide rails to complete the cleaning work of the photovoltaic panels on multiple groups of photovoltaic guide rails. Description of the Drawings

Detailed Embodiments

[0033] The present invention will be further described below in conjunction with the drawings and specific embodiments:

[0034] The specific embodiment is as followsFigure 1 , Figure 2 and Figure 3 , Figure 4 As shown, the present invention is an integrated adjustable photovoltaic bracket, which is arranged on a pile body and includes a base 1, a support assembly, and a photovoltaic frame body 2 erected on the base 1 by means of the support assembly. The photovoltaic frame body 2 is used for laying photovoltaic panels. The photovoltaic frame body 2 has a rectangular frame structure. The support assembly includes a first support rod 3, a second support rod 4 hinged to the photovoltaic frame body 2, and an umbrella-shaped bracket fixedly connected to the photovoltaic frame body 2. The umbrella-shaped bracket includes a main umbrella rib 5 and auxiliary umbrella ribs 6. The main umbrella rib 5 is fixedly connected to the photovoltaic frame body 2. A plurality of groups of auxiliary umbrella ribs 6 are arranged around the main umbrella rib 5. The auxiliary umbrella ribs 6 are connected between the overhanging end of the main umbrella rib 5 and the photovoltaic frame body 2. An expansion rod 7 is further arranged between the overhanging end of the main umbrella rib 5 and the base 1. The fixing point between the main umbrella rib 5 and the photovoltaic frame body 2 is offset from the hinge axes of the first support rod 3 and the second support rod 4 with respect to the photovoltaic frame body 2. The umbrella-shaped bracket enables the photovoltaic frame body 2 to have a swing freedom in the pitching direction by the push of the expansion rod 7.

[0035] In the present invention, by providing a disc-shaped base 1 and supporting the photovoltaic frame body 2 with a frame structure by spreading the first support rod 3 and the second support rod 4 in a V shape, as Figure 1 shown, the photovoltaic frame body 2 can swing around the hinge axes of the first support rod 3 and the second support rod 4 while being supported, as Figure 3 and Figure 4 shown. Among them, the thrust for swinging comes from the expansion rod 7 connected to the umbrella-shaped bracket. Through the integrated design of the present invention, the number of columns is streamlined, so that only one column is required for installing the photovoltaic bracket, greatly reducing the installation process and improving the deployment efficiency.

[0036] Furthermore, as Figure 3 and Figure 4 shown, the umbrella-shaped bracket further includes a reinforcing umbrella rib 8. One end of the reinforcing umbrella rib 8 is connected to the overhanging end of the main umbrella rib 5, and the other end is connected to the upper cross beam or the lower cross beam in the swinging direction of the photovoltaic frame body 2.

[0037] By providing the reinforcing umbrella rib 8, the effective length of the main umbrella rib 5 is fully utilized, so that the main umbrella rib 5, the auxiliary umbrella ribs 6, and the reinforcing umbrella rib 8 further form a stable triangular structure, increasing the overall rigidity, thereby reducing the overall tremor amplitude of the bracket when the cleaning mechanism is operating.

[0038] Furthermore, as Figure 1 and Figure 4As shown, a mask box 9 is provided on the base 1. The telescopic rod 7 is an electric telescopic rod arranged in the mask box 9. The telescopic end of the electric telescopic rod extends outside the mask box 9 and is hinged to the overhanging end of the main umbrella bone 5, and the fixed end of the electric telescopic rod is hinged inside the mask box 9.

[0039] The provided mask box 9 is used for installing the electric telescopic rod. By setting the electric telescopic rod, it can follow the change of the sun's angle to realize the adjustment of the photovoltaic bracket. The telescopic control of the electric telescopic rod is carried out by the controller according to the preset program.

[0040] Further, as Figure 2 shown, a photovoltaic guide rail 10 for laying photovoltaic panels is also installed on the photovoltaic frame 2. Two photovoltaic guide rails 10 form a group and multiple groups are arranged in parallel on the photovoltaic frame 2.

[0041] In the present invention, the photovoltaic panels are supported by the photovoltaic guide rails 10, so that the photovoltaic panels can be neatly arranged on the photovoltaic bracket, which is convenient for installation.

[0042] Further, as Figure 2 and Figure 5 、 Figure 6 shown, a cleaning mechanism is also provided on the photovoltaic guide rail 10. The cleaning mechanism includes a cleaning vehicle 11 and a rail-changing device. A roller brush 12 driven by a motor is provided on the cleaning vehicle 11. Traveling wheels 13 are provided on both sides of the cleaning vehicle 11. The traveling wheels 13 and the cleaning vehicle 11 are arranged in a C-shaped structure to surround the photovoltaic guide rail 10 and the photovoltaic panels. The cross-section of the photovoltaic guide rail 10 is a C-shaped groove structure. The traveling wheels 13 are inserted into the groove structure of the photovoltaic guide rail 10. The cleaning vehicle 11 has the freedom to move up and down along the photovoltaic guide rail 10 by means of the traveling wheels 13.

[0043] The cleaning vehicle 11 is clamped in the groove of the photovoltaic track by means of the traveling wheels 13. As Figure 5 shown, at this time, the photovoltaic panel is pressed under the roller brush 12 by the cleaning vehicle 11. The roller brush 12 is driven by a motor to rotate to clean the dirt covering the photovoltaic panel. As Figure 7 shown, the traveling wheels 13 are driven to rotate by a driving motor. Specifically, as shown in the figure, the driving motor drives the driving shaft 1301 to rotate. The driving shaft 1301 drives a set of bevel gears through a chain drive. Among them, the driven bevel gear is coaxially fixed with the driving pulley. The driving pulley is connected to the traveling wheel 13 through a belt drive. And the belt of this belt drive is also used as the wheel belt for the traveling wheel 13 to contact the photovoltaic guide rail 10, which improves the adhesion to the photovoltaic guide rail 10 and avoids slipping. The driving shaft 1301 straddles between the bases of the traveling wheels 13 on both sides and respectively makes the traveling wheels 13 on both sides rotate synchronously through a chain drive, so as to realize the stable forward and backward movement of the cleaning vehicle 11.

[0044] Further, the rail-changing device includes a fixing frame 14 provided at the end of the photovoltaic rail 10. A conveyor belt 15 is provided on the fixing frame 14. A carrier vehicle 16 is provided on the conveyor belt 15. The conveyor belt 15 has the freedom to reciprocate between adjacent groups of photovoltaic rails 10 by means of a rail-changing motor 17 provided on the fixing frame 14. The carrier vehicle 16 is fixed on the belt surface of the conveyor belt 15. A rail-changing rail 18 is provided on the carrier vehicle 16. The cross-section of the rail-changing rail 18 is the same as that of the photovoltaic rail 10 and is aligned with the photovoltaic rail 10 by the movement of the conveyor belt 15.

[0045] When the cleaning vehicle 11 travels back and forth along the photovoltaic rail 10, the photovoltaic panels on this group of photovoltaic rails 10 are cleaned. Subsequently, the cleaning vehicle 11 drives onto the rail-changing rail 18 of the carrier vehicle 16. At this time, the cleaning vehicle 11 is separated from the photovoltaic rail 10. Subsequently, the rail-changing motor 17 is started, causing the conveyor belt 15 to rotate and drive the carrier vehicle 16 to shift to the next group of photovoltaic rails 10. The cleaning vehicle 11 drives off the rail-changing rail 18 of the carrier vehicle 16 and enters the photovoltaic rail 10 connected to the rail-changing rail 18, thereby starting the next round of cleaning. This process is repeated until all the photovoltaic panels are cleaned. Subsequently, the cleaning vehicle 11 enters the carrier vehicle 16 and returns to the starting position with the conveyor belt 15.

[0046] As Figure 2 shown, the photovoltaic panels laid on the same group of photovoltaic rails 10 are arranged in a row and spaced at equal intervals. By spacing the photovoltaic panels, when dirt falls on the photovoltaic panels, the cleaning vehicle 11 can push the dirt off the photovoltaic panels nearby through cleaning, reducing the cleaning difficulty and improving the cleaning efficiency. Since the cleaning vehicle 11 travels along the photovoltaic rail 10, the separated photovoltaic panels do not affect its travel.

[0047] The operation method of the photovoltaic support described in this application includes the following construction steps:

[0048] S1. After the ground at the installation site is leveled, build piles according to the designed positions.

[0049] S2. After the photovoltaic support is transported to the site, assemble the base 1, the support assembly and the photovoltaic frame body 2 on the ground to form a complete empty frame body.

[0050] S3. Subsequently, hoist the entire empty frame body onto the piles and fix the base 1 through the bolts reserved on the piles to complete the installation of the empty frame body.

[0051] S4. Adjust the telescopic rod 7 to place the photovoltaic frame body 2 in a horizontal state, install the photovoltaic rail 10 and lay the photovoltaic panels on the photovoltaic rail 10, and tie the photovoltaic panel lines to the back side of the photovoltaic rail 10 to complete the laying of the photovoltaic panels.
