Description

Technical Field

[0001] The utility model relates to a multi-push rod type photovoltaic tracking bracket anti-torsion system, belonging to the technical field of photovoltaic power generation systems. Background Art

[0002] A tracking photovoltaic bracket is a photovoltaic bracket system that can automatically adjust the angle of the component to follow the movement of the sun to maximize the efficiency of the photovoltaic component in capturing solar energy, and is therefore widely used.

[0003] Existing multi-push rod tracking systems are increasingly used in photovoltaic power generation. Electric push rods transmit force through linear drive rods, driving the main beam to rotate, enabling the photovoltaic system to track the sun. This drive system can cause torque discrepancies at various points on the main beam when the push rods lose synchronization due to failures such as inconsistent push rod performance or control signal discrepancies. Therefore, an anti-torsion design is required to ensure system reliability and safety. Utility Model Content

[0004] The technical problem to be solved by the present invention is how to solve the problem that the multi-push rod tracking bracket is prone to inconsistent driving synchronization due to differences in push rod performance and control signals, resulting in different torques at various points on the main beam and torsion, which in turn leads to poor reliability and safety of the multi-push rod tracking bracket.

[0005] In order to solve the above technical problems, the utility model provides a multi-push rod photovoltaic tracking bracket anti-torsion system to avoid secondary damage to the main beam caused by abnormal operation of the multi-push rods, thereby improving the reliability and safety of the system.

[0006] In order to achieve the above technical objectives and the above technical effects, the present invention is implemented through the following technical solutions:

[0007] A multi-push rod photovoltaic tracking bracket anti-torsion system includes an electric push rod, a linear transmission rod and a main beam. The electric push rod drives the main beam to rotate through the force transmitted by the linear transmission rod. It also includes a tilt sensor assembly, a signal cable and a tracking controller. The tilt sensor assembly is arranged on the main beam and is used to detect the tilt angle at multiple points on the main beam to measure the angle difference at each position. The tracking controller is arranged on the main beam and is connected to the tilt sensor assembly through the signal cable to receive the angle difference data transmitted by the tilt sensor assembly. The tracking controller is connected to the electric push rod signal to control the start and stop of the main beam rotation according to the angle difference data measured by the tilt sensor assembly.

[0008] Preferably, the tilt sensor assembly includes tilt sensor 1 and tilt sensor 2, and the tilt sensor 1 and tilt sensor 2 are respectively arranged at two ends of the main beam.

[0009] Furthermore, the tracking controller is provided with a transmission interface connected to the first tilt sensor and the second tilt sensor, and the transmission interface is connected to the signal cable.

[0010] Furthermore, when the angle difference between the first inclination sensor and the second inclination sensor is greater than 5°, the tracking controller controls the main beam to stop rotating.

[0011] The utility model provides a multi-push rod photovoltaic tracking bracket anti-torsion system with the following advantages:

[0012] When the utility model is used, the torsion angle data of each point in the length direction of the main beam is collected in real time by the inclination sensor 1 and the inclination sensor 2 respectively arranged on the main beam, thereby reflecting whether the electric push rod is in an operating state. At the same time, the inclination angles collected in real time by the two inclination sensors are judged by using the angle difference algorithm. That is, when the inclination angle difference is greater than 5°, the tracking controller sends an instruction to stop the rotation of the main beam and enter the protection state, thereby avoiding secondary damage to the main beam caused by abnormal operation of multiple push rods, improving the reliability of the system, and the automatic protection setting can improve the safety of the system.

[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention.

[0019] Reference Figure 1-Figure 3A multi-push rod photovoltaic tracking bracket anti-torsion system includes an electric push rod 1, a linear transmission rod 2 and a main beam 3. The electric push rod 1 drives the main beam 3 to rotate through the force transmitted by the linear transmission rod 2. This is an existing technology and will not be described in detail.

[0020] Furthermore, a multi-push rod photovoltaic tracking bracket anti-torsion system also includes a tilt sensor assembly 4, a signal cable 5 and a tracking controller 6. The tilt sensor assembly 4 is arranged on the main beam 3 to detect the tilt angle at multiple points on the main beam 3 to measure the angle difference at each position. The tracking controller 6 is installed on the main beam 3 and is connected to the tilt sensor assembly 4 through the signal cable 5 to receive the angle difference data transmitted by the tilt sensor assembly 4. The tracking controller 6 is connected to the electric push rod 1 to control the start and stop of the rotation of the main beam 3 according to the angle difference data measured by the tilt sensor assembly 4.

[0021] Furthermore, the inclination sensor assembly 4 includes an inclination sensor 1 41 and an inclination sensor 2 42. The inclination sensor 1 41 and the inclination sensor 2 42 are respectively installed at both ends of the main beam 3 and are preferably arranged on the same side to ensure that the reference points of the angle detection data and the angle difference data are consistent, thereby ensuring the accuracy of the data.

[0022] Furthermore, a transmission interface connected to the inclination sensor 1 41 and the inclination sensor 2 42 is reserved on the tracking controller 6, and the transmission interface is connected to the signal cable 5. The inclination data is transmitted to the inside of the tracking controller 6 through the signal cable 5, and the angle difference algorithm is used to judge the rotation angle at the two points of the inclination sensor 1 41 and the inclination sensor 2 42. When the angle difference between the inclination sensor 1 41 and the inclination sensor 2 42 is greater than 5°, the tracking controller 6 controls the main beam 3 to stop rotating and enter a protection state, thereby improving the safety of the system. In this embodiment, the use of the inclination sensor, the angle difference algorithm and the setting of the transmission interface are all existing technologies and will not be elaborated on.
