TECHNICAL FIELD

[0001] The utility model belongs to the field of solar photovoltaic power generation, especially relates to a inclined single axis tracking photovoltaic array support. BACKGROUND

[0002] In the photovoltaic power generation system, the inclined single axis tracking support is one of the most commonly used photovoltaic array supports, and since the support is provided with an angle adjusting mechanism, the photovoltaic panel can track the rising and setting of the sun to rotate, so that the power generation capacity of the photovoltaic panel can be improved.

[0003] At present, the angle adjusting mechanism of the existing inclined single axis tracking photovoltaic support is one-to-one correspondence, and the angle adjusting mechanism can only adjust the angle of the photovoltaic panel itself, however, the photovoltaic support is generally arranged in an array, which requires the installation of the angle adjusting mechanism on each photovoltaic support, so as to cause complicated operation, high construction cost, and unnecessary waste of electric energy in the operation process, therefore, there are still defects and deficiencies in the prior art. CONTENT OF THE UTILITY MODEL

[0006] Preferably, the driving assembly comprises a bearing seat fixedly connected to the outer side of the support plate, a transmission rod is rotatably connected to the bearing seat, the transmission rod is in transmission connection with all the lead screws through bevel gear assemblies, a motor is fixedly connected to the outer side of the support plate through a support, and the output end of the motor is in transmission connection with the transmission rod.

[0007] Preferably, in order to increase the range of the angle of the photovoltaic panel tracking the sun, the telescopic rod has multiple sections.

[0008] Preferably, in order to stably support the inclined single shaft, the support assembly includes two vertically arranged columns, the bottom of which is installed on the ground, and the top of which is fixedly connected to a support bearing, and the inclined single shaft is rotatably connected in the support bearing.

[0009] Preferably, in order to stably support the photovoltaic panel, several support rods are fixedly connected to the top of the inclined single axis.

[0010] The beneficial effects of this utility model are as follows: (1) This utility model sets up a transmission rod so that the motor can drive several screw synchronous rotating shafts, and sets up an internal thread block and a telescopic rod so that the screw can drive several inclined single shafts to rotate synchronously, so that one motor can drive several photovoltaic panels to adjust their angles at the same time, thereby facilitating the simultaneous adjustment of the photovoltaic panel angle, reducing construction costs, reducing the consumption of electricity during operation, and thus promoting the application of inclined single-axis tracking photovoltaic brackets; (2) Since the extension range of the multi-section telescopic joint is larger, this can increase the range of horizontal movement of the internal thread block, thereby increasing the range of the photovoltaic panel tracking the sun angle, and thus increasing the power generation of the photovoltaic panel.

[0014] The present invention will be further described below with reference to the accompanying drawings. The following description is based on the accompanying drawings. Figure 1 The direction in the middle is the reference.

[0015] like Figures 1-2As shown, this utility model provides a single-axis tracking photovoltaic array support, including two opposing support plates 1. The bottom of the support plates 1 is installed on the ground. Several sets of arrayed support components are provided between the two support plates 1. Each set of support components is rotatably connected to a single-axis 2. A drive component is installed on the outer side of one of the support plates 1. Several horizontally arranged lead screws 5 are installed between the two support plates 1. The two ends of the lead screws 5 are rotatably connected to the two support plates 1 respectively. The end of each lead screw 5 near the drive component extends to the outer side of the support plate 1 and is connected to the drive component for transmission. The lead screw 5 is located below the single-axis 2. A telescopic rod 3 is installed between the lead screw 5 and the single-axis 2. One end of the telescopic rod 3 is fixedly connected to the single-axis 2. The other end of the telescopic rod 3 is hinged to an internal thread block 4, which is threaded onto the lead screw 5.

[0016] Specifically, in use, the photovoltaic array support is placed facing south, and the photovoltaic panels are fixed on the support rod 12. The drive device is connected to a PLC control system. The PLC control system can control the photovoltaic panels to rotate once every 15 minutes as the sun rises in the east and sets in the west. The photovoltaic panels and the PLC control system are not shown in the diagram. The connection relationship between the photovoltaic panels, the PLC control system, and the motor 6 is existing technology and will not be described here. When it is necessary to adjust the photovoltaic panels to rotate westward, the PLC control system starts the drive component. The drive component drives several lead screws 5 to rotate simultaneously. The rotating lead screws 5 drive several internal thread blocks 4 to move synchronously to the right. Since the telescopic end of the telescopic rod 3 is hinged to the internal thread block 4, the tilt angle between the telescopic rod 3 and the horizontal direction will increase as the telescopic end of the telescopic rod 3 moves to the right with the internal thread block 4. This causes the telescopic rod 3 to drive the inclined single shaft 2 to rotate westward, thereby enabling the photovoltaic panels on the inclined single shaft 2 to rotate with the sun rising in the east and setting in the west. Similarly, when it is necessary to adjust the photovoltaic panels to rotate eastward, the lead screw 5 is controlled to rotate in the opposite direction.

[0017] In some embodiments, the drive assembly includes a bearing seat 8 fixedly connected to the outside of the support plate 1, a transmission rod 7 rotatably connected to the bearing seat 8, and the transmission rod 7 being driven by all the lead screws 5 through a bevel gear assembly 9. A motor 6 is fixed to the outside of the support plate 1 by a bracket, and the output end of the motor 6 is driven by the transmission rod 7. Specifically, in use, when the motor 6 is started, the motor 6 can drive the transmission rod 7 to rotate, thereby causing the transmission rod 7 to drive several lead screws 5 to rotate simultaneously through the bevel gear assembly 9.

[0018] This invention sets up a transmission rod 7 so that the motor 6 can drive several lead screws 5 to rotate synchronously, and sets up an internal thread block 4 and a telescopic rod 3 so that the lead screws 5 can drive several inclined single shafts 2 to rotate synchronously. Thus, one motor 6 can drive several inclined single shafts 2 to track the photovoltaic bracket and adjust the angle at the same time, thereby reducing construction costs and energy consumption during operation, which is conducive to the promotion and application of inclined single shaft 2 tracking photovoltaic brackets.

[0019] In some embodiments, the telescopic rod 3 has multiple sections. Specifically, the multi-section telescopic joint has a larger extension range, which increases the range of horizontal movement of the internal threaded block 4, thereby increasing the range of the solar panel's tracking angle and thus improving the power generation of the solar panel.

[0020] In some embodiments, the support assembly includes two vertically arranged columns 10, with the bottom of the columns 10 mounted on the ground and the top of the columns 10 fixedly connected to a support bearing 11. The inclined single shaft 2 is rotatably connected within the support bearing 11. Specifically, the columns 10 can provide stable support for the inclined single shaft 2. Since the top of the columns 10 and the inclined single shaft 2 are rotatably connected through the support bearing 11, it is convenient to rotate the inclined single shaft 2.

[0021] In some embodiments, a plurality of support rods 12 are fixedly connected to the top of the inclined single shaft 2. Specifically, the support rods 12 facilitate the fixing of the photovoltaic panel, thereby improving the stability of the photovoltaic panel.

[0022] The above embodiments can be combined with each other.

[0023] The above embodiments are not intended to limit the shape, material, structure, etc. of this utility model in any way. Any simple modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of this utility model shall fall within the protection scope of this utility model.
