Detailed Description

In order to make the technical means, the creation features, the achievement purposes and the functions of the present invention easy to understand and understand, how to implement the present invention is further explained below with reference to the accompanying drawings and the detailed description.

Referring to fig. 1, the utility model provides a photovoltaic support adjusting system, which comprises a photovoltaic assembly 1, a support 2, a motor 3, a central control module and a vibration sensor 4; the support 2 is used for supporting the photovoltaic module 1, and the support 2 comprises a main shaft 21 which traverses the middle part of the photovoltaic module 1; the vibration sensor 4 is arranged on the main shaft 21, and the vibration sensor 4 is used for collecting current vibration data and transmitting the vibration data to the central control module; the motor 3 is used for controlling the rotation of the main shaft 21 so as to drive the photovoltaic module 1 to integrally rotate; the central control module is electrically connected with the motor 3 and the vibration sensor 4; the central control module is used for acquiring vibration data acquired by the vibration sensor 4, and when the vibration data is larger than a preset threshold value, the central control module automatically controls the motor 3 to work so as to adjust the angle of the photovoltaic assembly 1 and reduce the shaking of the photovoltaic assembly 1 and the support 2.

Preferably, the photovoltaic bracket adjusting system further comprises a speed reducer 5, wherein the speed reducer 5 is located in the middle of the main shaft 21; the main shaft 21 penetrates through the speed reducer 5 and is fixedly connected with the speed reducer 5 through a shaft sleeve; the motor 3 is located at one side of the speed reducer 5, and the motor 3 is used for directly controlling the rotation of the speed reducer 5 and indirectly controlling the rotation of the main shaft 21 through the speed reducer 5. By arranging the speed reducer 5, the violent rotation of the bracket 2 is avoided, and the reliability of the system is improved.

Preferably, the number of the vibration sensors 4 is two, and the two vibration sensors 4 are respectively disposed at both ends of the main shaft 21.

Further, the photovoltaic bracket adjusting system also comprises a tracking module electrically connected with the central control module; the tracking module is used for collecting the current illumination angle information and transmitting the illumination angle information to the central control module; when the vibration data are not greater than the preset threshold value, the central control module is also used for automatically controlling the motor 3 to work so as to adjust the angle of the photovoltaic assembly 1, and therefore the photovoltaic assembly 1 faces the illumination direction.

The utility model provides a photovoltaic support governing system's concrete work flow as follows: when no strong wind weather exists, the system works normally, and the photovoltaic module 1 automatically faces to the illumination direction. When the support shakes when being blown by wind, the support can be detected by the vibration sensor 4, and when the vibration data detected by the vibration sensor 4 is greater than a preset first threshold value, the situation that a large risk exists is shown. At the moment, the central control module automatically starts an adjusting program, the motor 3 is rotated by sending a command for operating the motor 3, and the bracket 2 is slowly rotated within a small range (such as-15 degrees to +15 degrees); meanwhile, the vibration sensor 4 continuously collects real-time vibration data, and the minimum jitter angle is obtained through real-time monitoring of the vibration data and data analysis; then the central control module controls the motor 3 to operate, and drives the bracket 2 to operate to the minimum shaking angle, so that the wind load borne by the bracket 2 can be protected to the maximum extent, and the photovoltaic solar panel is protected. In addition, when the support 2 is at the minimum shaking angle, if the vibration data detected by the vibration sensor 4 is smaller than a preset second threshold (the second threshold is far smaller than the first threshold), it indicates that the wind power may be recovered to normal, and the system recovers to normal operation; after normal work, if the vibration data are detected to be larger than the first threshold value again, the central control module starts the adjusting program again, and the like.

In addition, the system can also play a role in protecting the speed reducer 5, and can reduce the push-pull effect of the photovoltaic support on the speed reducer 5 due to wind load by adjusting the windward angle, reduce the stress condition of the speed reducer 5 and prolong the service life of the speed reducer 5.

For a plurality of photovoltaic devices in the same area, the system can also judge whether the speed reducer 5 fails in normal operation, through vibration data of different photovoltaic devices, if a certain vibration data and data of other devices have large deviation in a plurality of vibration data, the system can automatically give an alarm, and the speed reducer 5 or shaft sleeve on the support 2 is provided to cause problems and needs to be overhauled.
