Description

Technical Field

[0001] The present invention relates to the technical field of monitoring equipment, and in particular to tracking-type photovoltaic power station monitoring equipment. Background Art

[0002] Since the contact between photovoltaic panels and sunlight is directly related to the power generated by them, the real-time angle between photovoltaic panels and sunlight is extremely important in photovoltaic power generation. The dimming photovoltaic panel used in photovoltaic modules with announcement number CN114389538B includes a base, and a direction adjustment mechanism is provided on the top side of the base. The direction adjustment mechanism includes a first electric push rod fixedly connected to the base, the extended end of the first electric push rod is rotatably connected to the support seat through a pin shaft, the top of the support seat is fixedly installed with a support plate, the top of the support plate is fixedly installed with a photovoltaic panel, the top of the base is hinged with a second electric push rod, the extended end of the second electric push rod is hinged to the bottom of the support plate, and the angle of the support plate is adjusted by the cooperation of the first electric push rod and the second electric push rod.

[0003] However, we found in actual use that the angle of the support plate is adjusted by telescoping the first electric push rod and the second electric push rod, but when using such a telescopic drive device, there are the following problems: When starting and stopping, the motor may suddenly accelerate or decelerate, resulting in a sudden change in torque, which in turn causes vibration of the mechanical structure. This will directly cause the photovoltaic panel to vibrate, and the degree of vibration of the photovoltaic panel is usually different at different angles. At low angles (close to horizontal), the center of gravity is biased backward (close to the bracket shaft), the inertia moment during start and stop is small, and the vibration is lighter. At high angles, the center of gravity moves forward (away from the bracket shaft), and the torque demand during start and stop increases, which can easily lead to high-frequency vibration. If the structure height is different, a "nodding" phenomenon may also occur. For this reason, we propose a tracking photovoltaic power station monitoring device. Summary of the Invention

[0004] A technical problem to be solved by this application is: how to design a device that can reduce the vibration of the telescopic drive device when starting and stopping. In order to solve the above technical problems, the present application provides a tracking photovoltaic power station monitoring device, including a mounting bracket and a photovoltaic panel assembly, the photovoltaic panel assembly is provided with a wing, the mounting bracket is provided with an encoder, and the mounting bracket is provided with a transmission assembly for controlling the rotation of the wing.

[0005] The mounting bracket of the present invention is provided with a driving motor, a screw rod connected to the output end of the driving motor is rotatably provided on the mounting bracket, a shift seat sliding on the mounting bracket is threadedly connected to the screw rod, and the shift seat is connected to the transmission assembly.

[0006] The present invention provides two winglets and two transmission components.

[0007] The photovoltaic panel assembly of the present invention is provided with two fixing brackets on both side edges of the back side. The fixing brackets are both rotatably provided with a rotation axis, and the fins are respectively provided on adjacent rotation axes.

[0008] The transmission assembly of the present invention includes a gear arranged on a rotating shaft, a rack meshing with the gear is slidably arranged on the fixed bracket, a connecting bent rod is arranged on the rack, a connecting support rod is arranged on the connecting bent rod, and a deflection rod is rotatably arranged on the connecting support rod.

[0009] The sides of the fixed brackets of the present invention are all provided with guide support plates.

[0010] The wing of the present invention is a hollow airbag structure. Two positioning brackets are provided at the edge positions on both sides of the back of the photovoltaic panel assembly, and the wing is respectively provided on adjacent positioning brackets.

[0011] The transmission assembly of the present invention comprises a fixed cavity communicated with the wing, a piston rod is slidably arranged in the fixed cavity, and a deflection rod is rotatably arranged on the piston rod.

[0012] The sides of the positioning bracket of the present invention are all provided with guide side plates.

[0013] The present invention provides two fixed cavities and two piston rods, both of which are connected to the wing. A synchronization rod is provided between the two piston rods, and the synchronization rod is rotationally connected to the deflection rod.

[0014] The present invention has at least the following beneficial effects: 1. When adjusting the angle of the photovoltaic panel assembly, the staff can monitor the rotation status through the encoder and cooperate with the transmission assembly to drive the flaps to rotate a certain angle. When the photovoltaic panel assembly rotates, the flaps open quickly, and the airflow generates a reverse torque to offset the inertial vibration during the start-stop stage, thereby reducing the vibration of the telescopic drive equipment during start-stop; 2. The setting of the transmission component enables the rapid rotation of adjacent blades, while the setting of the drive motor and the screw can synchronously drive the blades on both sides to rotate at the same angle, thereby ensuring that the aerodynamic torque symmetrically offsets the vibration.

[0017] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0018] Example 1 See also Figure 1-Figure 5 , the present invention provides a technical solution: A tracking photovoltaic power station monitoring device includes a mounting bracket 1 and a photovoltaic panel assembly 2, wherein the photovoltaic panel assembly 2 is provided with a fin 3, the mounting bracket 1 is provided with an encoder 4, and the mounting bracket 1 is provided with a transmission assembly 5 for controlling the rotation of the fin 3; The mounting bracket 1 is composed of a column set on the ground and a rotating bracket rotatably set on the column, and the rotating bracket is composed of a rotating frame, a hollow rod body and a plurality of U-shaped rods. The plurality of U-shaped rods are respectively installed on the hollow rod body by bolts and clamps. The column and the rotating frame are connected by a rotating shaft, and a rotating seat is provided on the column and the rotating frame. An electric push rod is provided between the two rotating seats. Rubber shock absorbers are provided at both ends of the electric push rod to absorb the kinetic energy of the electric push rod during the start and stop stages. The fins 3 are installed at the back edge of the photovoltaic panel assembly 2, which can effectively utilize the airflow when unfolded. At the same time, they do not interfere with the normal movement of the photovoltaic panel assembly 2 when folded. In addition, when in use, they can also be used with the wind speed sensor of the power station to form wind load overload protection. When the wind speed sensor detects >15m / s, the fins 3 are forcibly retracted and locked. The fins 3 are designed with a blunt leading edge and a sharp trailing edge to ensure efficient energy conversion and avoid additional wind resistance. The absolute encoder 4 is directly mounted via a coupling, transmitting angles with zero backlash, and is equipped with an IP69K stainless steel housing and a built-in heater to prevent condensation. When the electric push rod drives the photovoltaic panel assembly 2 to rotate, the encoder 4 provides high-precision angle feedback and transmits the signal to the transmission assembly 5, which in turn drives the blade 3 to rotate.

[0019] The mounting bracket 1 is provided with a drive motor 6, and the mounting bracket 1 is rotatably provided with a screw rod 7 connected to the output end of the drive motor 6. The screw rod 7 is threadedly connected to a shift seat 8 that slides on the mounting bracket 1. The shift seat 8 is connected to the transmission assembly 5. Specifically, the drive motor 6, the screw rod 7 and the shift seat 8 are all arranged inside the hollow rod body. The surface of the hollow rod body is provided with a sliding groove for the sliding of the shift seat 8, and heat dissipation holes are provided on both sides for ventilation and heat dissipation of the drive motor 6. The shift seat 8 slides in the hollow rod body on the mounting bracket 1; The driving motor 6 rotates to drive the screw rod 7 to rotate. Since the shift seat 8 slides in the hollow rod body, when the screw rod 7 rotates, the shift seat 8 will shift, thereby driving the transmission component 5 to make corresponding adjustments. The transmission component 5 will directly drive the wing 3 to rotate synchronously. There are two of each of the winglets 3 and the transmission assembly 5. The two winglets 3 are respectively arranged at the edges on both sides of the back of the photovoltaic panel assembly 2, which can effectively utilize the airflow when unfolded. Through the arrangement of the transmission assembly 5, the drive motor 6 and the screw 7, the winglets 3 on both sides can be synchronously driven to rotate at the same angle, thereby ensuring that the aerodynamic torque symmetrically offsets the vibration.

[0020] During use, when the electric push rod drives the photovoltaic panel assembly 2 to rotate, the encoder 4 provides high-precision angle feedback and transmits the signal to the drive motor 6 and the transmission assembly 5. The drive motor 6 rotates to drive the screw rod 7 to rotate, and the shift seat 8 slides in the hollow rod body. When the screw rod 7 rotates, the shift seat 8 will shift, thereby driving the transmission assembly 5 to work and driving the blade 3 to rotate synchronously.

[0021] Example 2 See also Figures 1-6 , the present invention provides a technical solution: A tracking photovoltaic power station monitoring device, wherein two fixing brackets 9 are provided on both sides of the back edge of the photovoltaic panel assembly 2, and a rotating shaft 10 is rotatably provided on each of the fixing brackets 9, and the fins 3 are respectively provided on adjacent rotating shafts 10; The two wings 3 are respectively arranged on the rotating shaft 10, which enables the wings 3 to rotate synchronously with the adjacent rotating shaft 10, and when the wings 3 are reset, they can be retracted into the fixed bracket 9. This can reduce the airflow interference of the wings 3 on the photovoltaic panel assembly 2 when the wings are not working, and improve the stability of the photovoltaic panel assembly 2 during non-rotating adjustment; The transmission assembly 5 includes a gear 51 provided on the rotating shaft 10, a rack 52 slidably provided on the fixed bracket 9 and meshing with the gear 51, a connecting bent rod 53 provided on the rack 52, a connecting support rod 54 provided on the connecting bent rod 53, a deflection rod 15 rotatably provided on the connecting support rod 54, and the other end of the deflection rod 15 is rotatably connected to the shift seat 8; When the electric push rod drives the photovoltaic panel assembly 2 to rotate, the encoder 4 provides high-precision angle feedback and transmits the signal to the drive motor 6 and the transmission assembly 5. The drive motor 6 rotates to drive the screw rod 7 to rotate, and the shift seat 8 slides in the hollow rod body. When the screw rod 7 rotates, the shift seat 8 will shift, thereby driving the deflection rod 15 to adjust, and the connecting support rod 54 and the connecting bent rod 53 will also slide accordingly, thereby causing the rack 52 to slide and adjust on the fixed bracket 9. The shift of the rack 52 will drive the gear 51 to rotate, thereby causing the flaps 3 on both sides to rotate synchronously; The sides of the fixed bracket 9 are provided with guide support plates 11. The installation of the guide support plates 11 can significantly improve the vibration reduction performance and system stability by optimizing the airflow distribution and enhancing the aerodynamic control. That is, when the wing 3 is retracted into the fixed bracket 9, the airflow interference of the wing 3 on the photovoltaic panel assembly 2 when it is not working can be further reduced.

[0022] Example 3 See also Figure 1-Figure 5 、 Figure 7-10 , the present invention provides a technical solution: A tracking photovoltaic power station monitoring device, wherein the fin 3 is a hollow airbag structure, two positioning brackets 12 are provided at the edges of both sides of the back of the photovoltaic panel assembly 2, and the fins 3 are respectively provided on adjacent positioning brackets 12; The wing 3 is made of a flexible composite material (such as polyurethane-coated polyester fiber), weighing only 15% to 30% of a rigid wing 3. Its thickness after deflation is less than 5 cm, reducing its transport volume by 90%. Its foldability makes transportation and installation more convenient. Furthermore, even if the wing 3 is broken, repairing it is simpler than repairing a rigid wing 3 structure. The wing 3 of this solution is also designed with a blunt leading edge and a sharp trailing edge to ensure efficient energy conversion and avoid additional wind resistance. In some unexpected situations, the flexible airbag significantly reduces the mortality rate of bird strikes, which is conducive to ensuring biocompatibility. The transmission assembly 5 includes a fixed cavity 13 connected to the wing 3, a piston rod 14 is slidably provided in the fixed cavity 13, a deflection rod 15 is rotatably provided on the piston rod 14, and the other end of the deflection rod 15 is rotatably connected to the shift seat 8; When the electric push rod drives the photovoltaic panel assembly 2 to rotate, the encoder 4 provides high-precision angle feedback and transmits the signal to the drive motor 6 and the transmission assembly 5. The drive motor 6 rotates to drive the screw rod 7 to rotate, and the shift seat 8 slides in the hollow rod body. When the screw rod 7 rotates, the shift seat 8 will shift, thereby driving the deflection rod 15 to adjust, and the piston rod 14 will also slide accordingly, pushing the gas inside the fixed cavity 13 into the inside of the wing 3, thereby making the wing 3 on both sides inflated synchronously. Conversely, the drive motor 6 is reversed, and the shift seat 8 and the piston rod 14 will also reset, which will cause the wing 3 to be compressed and retracted; The sides of the positioning bracket 12 are each provided with a guide side plate 16. After adopting the airbag wing 3, the thickness will be greatly reduced in the compressed state, which reduces the impact on the airflow to a certain extent. The installation of the guide side plate 16 can further improve the vibration reduction performance and system stability by optimizing the airflow distribution and enhancing the aerodynamic control. That is, when the wing 3 is retracted into the fixed bracket 9, the airflow interference of the wing 3 on the photovoltaic panel assembly 2 when it is not working can be further reduced.

[0023] Example 4 See also Figure 11 , the present invention provides a technical solution: A tracking photovoltaic power station monitoring device, wherein two fixed chambers 13 and two piston rods 14 are provided, both of which are connected to the fins 3. A synchronization rod 17 is provided between the two piston rods 14. The synchronization rod 17 is rotatably connected to the deflection rod 15, and the other end of the deflection rod 15 is rotatably connected to the shift seat 8. Under this design, both sides of the fin 3 can be ventilated inward, and the bilaterally symmetrical air intake forms convection. The pressure gradient is balanced through the Bernoulli effect in fluid dynamics, avoiding the low-pressure area at the end caused by unilateral inflation. Especially for the case where the airbag is longer in this solution, it is more conducive to the uniformity of airflow distribution. In addition, dual-sided air intake allows for simultaneous inflation from both sides, shortening the inflation time, which is very important for applications that require fast response (such as real-time adjustment of photovoltaic panel angles). In addition, the dual-sided synchronous pressure relief speed is also increased by 2 times; If one of the air intakes on a dual-side system fails, the other can continue to operate, potentially reducing downtime and maintenance costs. Whereas if a single-side intake fails, the entire airbag will not function properly and may require immediate repair. When the electric push rod drives the photovoltaic panel assembly 2 to rotate, the encoder 4 provides high-precision angle feedback and transmits the signal to the drive motor 6 and the transmission assembly 5. The rotation of the drive motor 6 drives the screw rod 7 to rotate, and the shift seat 8 slides in the hollow rod body. When the screw rod 7 rotates, the shift seat 8 will shift, thereby driving the deflection rod 15 to adjust, and the synchronization rod 17 and the piston rods 14 on both sides will also slide accordingly, and at the same time push the gas inside the two fixed cavities 13 into the interior of the vane 3, thereby making the vanes 3 on both sides inflated synchronously. Conversely, the drive motor 6 reverses, and the shift seat 8 and the piston rod 14 will also reset, which will cause the vane 3 to be compressed and retracted.
