For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0027] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0028] See also Figure 1 The embodiment of the present application provides a photovoltaic bracket, including a power component 2 and a plurality of unit structures 1, wherein the unit structure 1 includes a column 10, a support component 20 and a transmission component 30, wherein the support component 20 is rotatably connected to the column 10 for supporting the photovoltaic panel; the transmission component 30 is arranged on the column 10, the transmission component 30 is transmission-connected to the support component 20, and is used to drive the support component 20 to rotate; wherein the power component 2 is transmission-connected to the transmission component 30, and is used to provide power to the transmission component 30.

[0029] In practical applications, the unit structure 1 usually includes two columns 10, the columns 10 are vertically set on the ground, the support component 20 is rotatably set on the column 10, and then the photovoltaic panel is laid on the support component 20. The power component 2 provides the support component 20 with rotational power through the transmission component 30, wherein the output torque of the power component 2 is amplified through the transmission action of the transmission component 30, so that the support component 20 can be driven to rotate relative to the column 10, thereby driving the photovoltaic panel to rotate. Optionally, the power component 2 can be a motor.

[0030] Compared with the prior art, the present application provides a photovoltaic bracket, including a power component 2 and a plurality of unit structures 1, wherein the unit structure 1 includes a column 10, a support component 20 and a transmission component 30, wherein the support component 20 is used to support the photovoltaic panel, so that the installation of the photovoltaic panel is more stable, and the power component 2 provides the support component 20 with rotational power through the transmission component 30, and the rotation of the support component 20 drives the photovoltaic panel to rotate, and the transmission component 30 amplifies the torque output by the power component 2, so that the power component 2 can achieve a large output torque with a small input torque. Compared with the traditional bracket structure, the size and weight of the power component 2 are greatly reduced, and the driving cost is reduced. By splicing and installing a plurality of unit structures 1, the phenomenon that a long axis of the traditional bracket passes through the bottom is changed. During installation, adjusting the position of the column 10 in the unit structure 1 is obviously more convenient than adjusting the positions of more than a dozen columns 10, thereby saving installation time.

[0031] See also Figure 2 and Figure 3 The supporting component 20 includes a plurality of supporting beams 201, and the transmission component 30 includes a pin wheel 301. The plurality of supporting beams 201 are symmetrically arranged on both sides of the column 10 and connected to the photovoltaic panels, and their length direction extends along the layout direction of the photovoltaic panels; the pin wheel 301 is arranged on the column 10 along a length direction perpendicular to the supporting beam 201, and its two ends are connected to the supporting beams 201 on both sides. The power component 2 is in transmission connection with the pin wheel 301 and drives the pin wheel 301 to rotate. By symmetrically arranging the support beams 201 on both sides of the column 10, the weight of the photovoltaic panel is dispersed to multiple support beams 201, reducing the burden of a single support beam 201, and the pin wheel 301 is connected to the support beams 201 on both sides. When the power component 2 drives the pin wheel 301 to rotate, the pin wheel 301 drives the support beam 201 to rotate. The weight borne by a single support beam 201 is smaller, so it is lighter when rotating; and the support beam 201 is equivalent to a fulcrum, shortening the force arm between the photovoltaic panel and the column 10, reducing the torque generated by the self-weight of the photovoltaic panel, making the installation of the photovoltaic panel more stable, and reducing the eccentric moment generated by the rotation of the photovoltaic panel, thereby reducing the rotational torque required to be provided by the power component 2.

[0032] The transmission component 30 includes a connection end 302, a driving member 303 and a gear 304. The driving member 303 is connected to the power component 2 through the connection end 302. The gear 304 is connected to the output end of the driving member 303. The pin wheel 301 is partially arc-shaped. The gear 304 is arranged at the arc position of the pin wheel 301 and meshes with the pin wheel 301. In this embodiment, the pin wheel 301 is semicircular, and the gear 304 is arranged in the middle of the pin wheel 301 and meshes with the pin wheel 301. When the power component 2 provides power to the driving member 303, the driving member 303 drives the gear 304 to rotate, and the gear 304 drives the pin wheel 301 to rotate, thereby realizing the rotation of the photovoltaic panel. The pin wheel 301 can amplify the torque transmitted by the gear 304, so the power component 2 can use a motor with a smaller torque to achieve a larger output torque with a smaller input torque. Optionally, the driving member 303 may adopt a reducer. The transmission member 30 of the above structure has a self-locking function. Placing the self-locking mechanism at the input end greatly reduces the volume and weight of the self-locking mechanism, and also reduces the cost.

[0033] Please refer again Figure 3The support component 20 also includes a support rod 202, which is rotatably arranged on the column 10 perpendicular to the length direction of the support beam 201. The support rod 202 is connected to the support beam 201, and the two ends of the pin wheel 301 are respectively connected to the two ends of the support rod 202. The support rod 202 is connected to the support beam 201 on both sides of the column 10 to bear the gravity of the support beam 201, and then the support rod 202 transfers the gravity to the column 10 to reduce the gravity borne by the transmission component 30. At the same time, the two ends of the pin wheel 301 are connected to the support rod 202, and the pin wheel 301 can drive the support rod 202 to rotate, thereby driving the support beam 201 to rotate, and then driving the photovoltaic panel to rotate.

[0034] Among them, the support rod 202 is detachably connected to the support beam 201. When in use, the support component 20 can be transported to the construction site in parts for easy transportation. Under long-term use, the operator can replace and repair the support component 20, and the support rod 202 can be detachably connected to the support beam 201 through stirrups or bolts.

[0035] The support member 20 further includes a support column 203, which is disposed between the photovoltaic panel and the column 10, the support column 203 is fixedly connected to the column 10, and the photovoltaic panel is rotatably connected to the support column 203. The support column 203 can be fixedly connected to the column 10 by bolts, which is convenient for disassembly and installation. In some complex areas, it is not suitable to transport the long column 10, so the support column 203 and the column 10 can be transported separately to the construction site, and then the two can be installed together.

[0036] The support member 20 further includes a rotating plate 204, which is rotatably connected to the column 10, the support rod 202 is connected to the rotating plate 204, and the photovoltaic panel is arranged on the rotating plate 204. In this embodiment, the rotating plate 204 is rotatably connected to the support column 203, the support rod 202 is rotatably connected to the support column 203 through the rotating plate 204, and the rotating plate 204 extends along the length direction of the photovoltaic panel, which increases the contact area between the support column 203 and the photovoltaic panel, plays a role in supporting the photovoltaic panel, and makes the photovoltaic panel more stable when rotating.

[0037] Please refer again Figure 2The photovoltaic bracket also includes a connector 40. The transmission components 30 in each unit structure 1 are connected in series with the power component 2 through multiple connectors 40 to form a series structure. In this device, multiple unit structures 1 share the same power component 2. To achieve this purpose, multiple transmission components 30 are connected in series through connectors 40. Specifically, the connecting ends 302 between two adjacent transmission components 30 are connected through connectors 40, and then the multiple transmission components 30 connected in series are connected to the output end of the power component 2 through connectors 40. When the power component 2 drives the connecting component 40 connected thereto to rotate, the connecting component 40 provides power to the driving component 303 through the connecting end 302, and the driving component 303 drives the gear 304 to rotate. At the same time, the connecting component 40 drives the next connecting component 40 connected thereto to rotate, and transmits the power to the last connecting component 40 in sequence, so that one power component 2 provides power to multiple transmission components 30.

[0038] In this embodiment, the power component 2 is arranged in the middle of the series structure. Multiple unit structures 1 are symmetrically arranged on both sides of the power component 2 and connected to the power component 2 through a connector 40. The power component 2 provides the same power to the unit structures 1 on both sides, and the distance of force transmission is the same. When the pin wheel 301 drives the photovoltaic panel to rotate, the rotation angles of multiple photovoltaic panels are consistent.

[0039] See also Figure 4 and Figure 5 The photovoltaic bracket also includes a universal joint 50, and the connecting member 40 is connected to the transmission component 30 through the universal joint 50. In actual applications, the length of photovoltaic laying is relatively long, and when constructing in some mountainous areas, the ground is undulating. The angle at which the traditional photovoltaic brackets can rotate relative to each other is very small, and it is difficult to be applied to such terrain. The present application adopts a universal joint 50 for connection. The universal joint 50 is connected at the input end. Compared with the traditional structure that uses a universal joint 50 to connect at the output end, the torque of the universal joint 50 is greatly reduced. Therefore, the present application can use a smaller universal joint 50, which is more convenient to install in mountainous areas or places with uneven ground. Through the universal joint 50, each unit structure 1 can rotate relatively at a larger angle to meet various terrain requirements. Among them, the universal joint 50 is two connecting shafts that are rotatably connected together, and the two connecting shafts can adjust the angle between the two from two dimensions.

[0040] Different from the prior art, the embodiment of the present application provides a photovoltaic bracket, including a power component 2 and a plurality of unit structures 1, wherein the unit structure 1 includes a column 10, a support component 20 and a transmission component 30, wherein the support component 20 is rotatably connected to the column 10 for supporting the photovoltaic panel; the transmission component 30 is arranged on the column 10, the transmission component 30 is transmission-connected to the support component 20, and is used to drive the support component 20 to rotate; wherein the power component 2 is transmission-connected to the transmission component 30, and is used to provide power to the transmission component 30. Compared with the prior art, the present application provides a photovoltaic support, including a power component 2 and a plurality of unit structures 1, wherein the unit structure 1 includes a column 10, a support component 20 and a transmission component 30, wherein the support component 20 is used to support the photovoltaic panel, so that the installation of the photovoltaic panel is more stable, and the power component 2 provides the support component 20 with rotational power through the transmission component 30, and the transmission component 30 amplifies the torque output by the power component 2, so that the power component 2 can achieve a large output torque with a small input torque, and compared with the traditional support structure, the size and weight of the power component 2 are greatly reduced, and the driving cost is reduced; the transmission component 30 of the device also has a self-locking function, and the self-locking mechanism is arranged at the output The input end is greatly reduced, the volume and weight of the self-locking mechanism are greatly reduced, and the cost is also reduced; by splicing and installing multiple unit structures 1, the phenomenon that a long axis of the traditional bracket runs through the end is changed. During installation, it is obviously more convenient to adjust the position of the column 10 in the unit structure 1 than to adjust the positions of more than a dozen columns 10, which saves installation time; the unit structures 1 are connected by a universal joint 50. Since the universal joint 50 is connected at the input end, a smaller universal joint 50 can be used, which is very convenient for installation in mountains or places with uneven ground, and plays a role in terrain tracking. Compared with the traditional structure with a universal joint 50 connected at the output end, the torque and cost of the universal joint 50 are greatly reduced.

[0041] The embodiments of this specific implementation method are all preferred embodiments of the present invention, and are not intended to limit the protection scope of the present invention. Therefore, any equivalent changes made based on the structure, shape, and principle of the present invention should be included in the protection scope of the present invention.
