[0032] Reference Figure 1 As shown, some embodiments of this application provide a new energy wind farm circuit stability control device, including: a control box 1, a locking structure and a base 9.

[0033] The control box 1 contains a power module 2, a control board 3, a main chip 4, a communication module 5, and a serial port 6. The control board 3 is located on one side of the power module 2, the main chip 4 is located in the central area of ​​the control board 3, and the communication module 5 and the serial port 6 are located on the side of the control board 3 away from the power module 2.

[0034] The locking structure includes a locking base 10 and a locking frame 11. The locking base 10 is located in the bottom peripheral area of ​​the control box 1, and the locking frame 11 is located in the top peripheral area of ​​the control box 1. The locking frame 11 and the locking base 10 are fixedly connected by a fastening structure. The base 9 is located at the bottom of the control box 1 and the locking structure and is used to support the control box 1 and the locking structure.

[0035] The new energy wind farm circuit stabilization control device provided in this application integrates key components such as a control box 1, a power module 2, a control board 3, a main chip 4, a communication module 5, a serial port 6, and a circuit module 7 to form a highly integrated control system. The fixed connection and reasonable layout between the modules effectively reduce interference during signal transmission, ensuring stable circuit operation. In particular, the main chip 4, located in the central area of ​​the control board 3, optimizes the signal processing path, effectively improving the system's response speed and stability. Simultaneously, by setting a base 9 and a locking structure on the outside of the control box 1, and fixing it to the locking base 10 via a locking frame 11, the control box 1 receives good mechanical support, effectively enhancing its overall structural strength and thus strengthening its anti-interference capability, reducing interference during signal transmission, and ensuring stable circuit operation. Furthermore, the locking structure on the outside of the control box 1 provides good protection, effectively preventing component loosening due to vibration or external impact, ensuring stable circuit operation while effectively improving the device's safety performance.

[0036] Specifically, control box 1 is the outer shell of the entire device, which can be made of high-strength metal materials and has good dustproof, waterproof and impact-resistant properties. The internal space of control box 1 can be rationally divided into multiple areas for installing different functional modules.

[0037] Power module 2 is located inside control box 1. The outer wall of power module 2 can be fixedly connected to control box 1, specifically through methods such as adhesive bonding, welding, or screw connection. The main function of power module 2 is to provide a stable power supply for the entire device. Power module 2 can adopt a highly efficient and energy-saving power design scheme, capable of adapting to the complex and variable power environment of new energy wind farms. The specific structure of power module 2 includes, but is not limited to, input terminals, filtering circuits, voltage regulation circuits, and output terminals.

[0038] The control board 3 is located inside the control box 1 and on one side of the power module 2. The control board 3 is the core control unit of the entire device, primarily responsible for coordinating the operation between the various modules. The control board 3 can use a high-performance PCB board with various electronic components mounted on its surface, including but not limited to resistors, capacitors, and transistors.

[0039] The main chip 4 is located in the central area of ​​the control board 3 and is the core component of the control board 3. The main chip 4 can use a high-performance microprocessor, possessing powerful data processing capabilities and abundant interface resources. The main chip 4 can achieve precise control of each module through its internal program.

[0040] The communication module 5 is located inside the control box 1, on the side of the control board 3 furthest from the power module 2. The outer wall of the communication module 5 can be fixedly connected to the control box 1, specifically through methods such as adhesive bonding, welding, or screw connection. The main function of the communication module 5 is to enable data communication between the device and external systems. The communication module 5 supports multiple communication protocols, including but not limited to RS485 and Ethernet, to meet the diverse communication needs of new energy wind farms.

[0041] Serial port 6 is located inside control box 1, on the side of control board 3 furthest from power module 2. Specifically, serial port 6 can be installed below communication module 5, with its outer wall fixedly connected to control box 1, thus securing it within the control box 1. Serial port 6 is primarily used to connect external devices for serial data transmission. It can adopt a standard serial interface design, offering strong compatibility and ease of expansion.

[0042] Circuit module 7 is located outside the control box 1, on the side away from the control board 3, opposite to the communication module 5 and serial port 6. Circuit module 7 is the power regulation unit of the device, primarily responsible for the stable control of the wind farm circuit. The internal components of circuit module 7 may include, but are not limited to, multiple relays, contactors, and protective elements, enabling rapid switching and protection of the circuit.

[0043] In addition, a main switch 8 can be installed on the outside of the control box 1, located on the same side of the control box 1 as the circuit module 7. Specifically, the main switch 8 can be installed below the circuit module 7. The main switch 8 is the main power control switch of the device, mainly used for manually controlling the power supply to and from the device. The main switch 8 can use highly reliable switching elements and has overload protection and short-circuit protection functions. The installation of the main switch 8 allows for rapid power cut-off in emergencies, avoiding safety accidents caused by circuit faults and effectively improving the safety performance of the device.

[0044] The locking structure is located in the outer perimeter of the control box 1. The locking structure includes a locking base 10 and a locking frame 11. The locking base 10 is located in the bottom outer perimeter of the control box 1, and the locking frame 11 is located in the top outer perimeter of the control box 1. The locking frame 11 and the locking base 10 are fixedly connected by a fastening structure to form a locking structure surrounding the outer perimeter of the control box 1. The locking structure effectively enhances the overall structural strength of the control box 1, thereby effectively enhancing the device's anti-interference capability, reducing interference during signal transmission, and ensuring stable circuit operation. It also provides good protection, effectively preventing components from loosening due to vibration or external impact. While ensuring stable circuit operation, it effectively improves the safety performance of the device.

[0045] The control box 1 is externally provided with a base 9, which is located at the bottom of the control box 1 and the locking structure to support them. The base 9 can be made of high-strength material to provide stable support for the control box 1 and the locking structure, thereby ensuring overall stability and durability. Specifically, a locking seat 10 can be installed on the top of the base 9, and a locking frame 11 is provided on the top of the locking seat 10. The locking frame 11 is fixed to the locking seat 10 by a fastening structure.

[0046] In some embodiments, refer to Figure 2 and Figure 3 As shown, the locking base 10 is an arc-shaped base with an open upper end, and the locking frame 11 is an arc-shaped frame with an open lower end. The arc-shaped frame and the arc-shaped base together form a ring structure surrounding the control box 1. With this arrangement, after the locking frame 11 and the locking base 10 are fixedly connected by the fastening structure, a ring-shaped clamping and locking structure surrounding the outer peripheral wall of the control box 1 can be formed. The ring structure can effectively distribute the force, enhance the overall structural strength of the control box 1, improve the stability of the structure, and thus effectively enhance the anti-interference ability of the device.

[0047] In specific implementation, the control box 1 can adopt a horizontally placed cylindrical structure. The outer peripheral wall of the control box 1 is cylindrical. The shape of the ring structure formed by the arc-shaped seat and the arc-shaped frame is adapted to the shape of the outer peripheral wall of the control box 1, so as to realize the function of clamping the outer peripheral wall of the control box 1 by using the arc-shaped seat and the arc-shaped frame.

[0048] In some embodiments, refer to Figure 3 As shown, the arc-shaped base has first connecting ears 101 at both ends along the circumference, and the arc-shaped frame has second connecting ears 111 at both ends along the circumference. The first connecting ears 101 and the second connecting ears 111 are arranged in a one-to-one correspondence. One of the first connecting ears 101 and the second connecting ears 111 has a mounting hole, and the other has a threaded seat 13. The fastening structure includes a fastening bolt 12, which passes through the mounting hole and is threadedly connected and fixed to the threaded seat 13. This arrangement allows the arc-shaped base and the arc-shaped frame to be fixedly connected by the threaded engagement of the fastening bolt 12 and the threaded seat 13. The structure is simple, the assembly is convenient, and the locking force of the fastening bolt 12 and the threaded seat 13 can be adjusted as needed.

[0049] In some embodiments, the first connecting ear 101 is provided with a threaded seat 13, and the second connecting ear 111 is provided with a mounting hole. The locking structure also includes an elastic sleeve 14, which is located on the side of the second connecting ear 111 facing away from the first connecting ear 101. The fastening bolt 12 passes through the elastic sleeve 14 and the mounting hole in sequence, and is threadedly connected and fixed to the threaded seat 13. Specifically, the elastic sleeve 14 is made of elastic material and has good extensibility and wear resistance. The function of the elastic sleeve 14 is to fix and support the fastening bolt 12 installed thereon, ensuring that the fastening bolt 12 will not be displaced during use, thereby ensuring the reliability of the fixed connection between the fastening bolt 12 and the threaded seat 13. The fastening bolt 12 passes through the elastic sleeve 14 and the mounting hole in sequence, and is threadedly connected and fixed to the threaded seat 13. The tightness of the elastic sleeve 14 can be adjusted by rotating the fastening bolt 12, thereby adjusting the locking force between the fastening bolt 12 and the threaded seat 13, and thus ensuring the reliability of the locking fit between the locking seat 10 and the locking frame 11.

[0050] Of course, the control box 1 is not limited to a horizontally placed cylindrical structure; it can also be a rectangular box structure, with the outer peripheral wall of the control box 1 having a rectangular surface. In this embodiment, the locking seat 10 and the locking frame 11 can be configured to match the shape of the outer peripheral wall of the control box 1. For example, the locking seat 10 can be a square groove structure with an open upper end, and the locking frame 11 can be a square groove structure with an open lower end. The locking frame 11 and the locking seat 10 together form a rectangular cross-section structure surrounding the outer peripheral wall of the control box 1, which can also achieve the clamping and locking effect on the outer peripheral wall of the control box 1, effectively enhancing the overall structural strength of the control box 1, thereby effectively enhancing the anti-interference capability of the device.

[0051] In some embodiments, refer to Figure 2 As shown, there are at least two locking structures, and these at least two locking structures are spaced apart along the length of the control box 1 on its periphery. (Refer to...) Figure 2 As shown, Figure 2 The horizontal arrow in the diagram indicates the length direction of control box 1. This means that the number of locking structures is not limited to one; it can be two, three, or more. This arrangement utilizes multiple locking structures to create a clamping and locking effect on control box 1, thereby improving the overall structural strength of control box 1.

[0052] For example, refer to Figure 2 and Figure 3As shown, two locking seats 10 can be installed on the top of the base 9, and the two locking seats 10 are symmetrically distributed on both sides of the top of the base 9. The locking seats 10 can adopt an arc-shaped design, which can effectively distribute the force and improve the stability of the structure. Each of the two locking seats 10 is provided with a locking frame 11 on its top. The locking frame 11 can adopt an arc-shaped design that matches the shape of the arc-shaped seat. The locking frame 11 is fixed to the locking seat 10 by fastening bolts 12 or other fasteners.

[0053] In some embodiments, refer to Figure 1 and Figure 4 As shown, the new energy wind farm circuit stability control device also includes a support structure connected to the bottom of the base 9, which provides good support for the control box 1, the locking structure, and the base 9. Specifically, the support structure includes a support frame 15 and a clamping ring 16. The support frame 15 is fixedly connected to the bottom of the base 9. One end of the support frame 15 is rotatably connected to one end of the clamping ring 16 via a hinge pin 17. A connecting seat 18 is fixed to the end of the support frame 15 away from the hinge pin 17, and a connecting frame 19 is fixed to the end of the clamping ring 16 away from the hinge pin 17. The connecting frame 19 and the connecting seat 18 are detachably fixedly connected by a fastening assembly. This arrangement allows the clamping ring 16 to rotate relative to the support frame 15 around the hinge pin 17, thereby changing the opening and closing state of the clamping ring 16 relative to the support frame 15, so as to facilitate the installation of the device in a suitable location in the new energy wind farm (e.g., on the support structure or other components of the new energy wind farm).

[0054] In practical implementation, a support frame 15 is installed at the bottom of the base 9. The support frame 15 can be made of sturdy metal material and has a high load-bearing capacity. A clamping ring 16 is connected to one end of the support frame 15. One end of the clamping ring 16 is hinged to one end of the support frame 15 via a hinge pin 17. The function of the hinge pin 17 is to realize the rotation and fixation of the clamping ring 16. The clamping ring 16 can be made of elastic material and can fit tightly against the support frame 15.

[0055] A connecting seat 18 is fixed to the end of the support frame 15 away from the hinge pin 17. The connecting seat 18 can be a U-shaped seat with a groove structure that opens away from the hinge pin 17. The U-shaped structure design of the connecting seat 18 provides high stability and load-bearing capacity, and facilitates the installation and fixation of fastening components on the connecting seat 18. A connecting bracket 19 is fixed to the end of the clamping ring 16 away from the hinge pin 17. The connecting bracket 19 can be made of lightweight material to facilitate the installation and disassembly of the connecting bracket 19.

[0056] In some embodiments, refer to Figure 4As shown, the support frame 15 has a first arc-shaped surface on its side facing the clamping ring 16, and the clamping ring 16 has a second arc-shaped surface on its side facing the support frame 15. An annular clamping area is formed between the first and second arc-shaped surfaces. This arrangement utilizes the first and second arc-shaped surfaces to clamp the brackets and other components of the new energy wind farm, enabling the device to be installed in a suitable location within the wind farm. The arc-shaped design effectively distributes the force, ensuring the stability of the installation.

[0057] In some embodiments, refer to Figure 4 As shown, the fastening assembly includes an adjusting bolt 20 and an adjusting nut 21. The adjusting bolt 20 passes through the connecting bracket 19 and the connecting seat 18, and the adjusting nut 21 is sleeved on the adjusting bolt 20, with the position of the adjusting nut 21 on the adjusting bolt 20 being adjustable. Specifically, the adjusting bolt 20 can be made of high-strength material with a special surface treatment, exhibiting good wear resistance and corrosion resistance. The adjusting nut 21 is connected to the adjusting bolt 20 via threads, and the position of the adjusting bolt 20 can be adjusted by rotating the adjusting nut 21, thereby achieving both fixing and position adjustment of the connecting bracket 19.

[0058] The working principle of the new energy wind farm circuit stability control device provided in the embodiments of this application will be described in detail below.

[0059] (1) Equipment startup preparation:

[0060] Check that the main switch 8 is in the off position to ensure the device is not powered on and to guarantee the safety of installation and inspection personnel. Perform a visual inspection of all components, including the control box 1, power module 2, control board 3, communication module 5, serial port 6, and circuit module 7, to confirm there is no damage, looseness, or other abnormalities. Inspect the mounting structure components, including the base 9, locking seat 10, locking bracket 11, ferrule, fastening bolt 12, threaded seat 13, support frame 15, clamping ring 16, hinge pin 17, connecting seat 18, connecting frame 19, adjusting bolt 20, and adjusting nut 21, to ensure secure connections and normal operation of the adjusting components.

[0061] (2) Power connection and power supply:

[0062] Connect the external power supply to the input terminal of power module 2 using a suitable cable, ensuring a secure connection that complies with electrical specifications. Close the main switch 8, and power module 2 will begin operation. Its input terminal receives the external power input, which is filtered by a filter circuit to remove noise and interference signals. The voltage is then stabilized at a suitable output value by a voltage regulator circuit. Finally, the output terminal provides a stable power supply to the control board 3, communication module 5, serial port 6, and other modules inside control box 1, as well as the external circuit module 7.

[0063] (3) Control board initialization and configuration:

[0064] Control board 3 starts up after receiving power. Main chip 4 begins executing its internal initialization program, performing self-tests on itself and all connected modules. Main chip 4 checks the status of electronic components such as resistors, capacitors, and transistors on control board 3 to ensure the hardware system of control board 3 is functioning correctly. Main chip 4 initializes and configures communication module 5, serial port 6, etc., through its internal program, setting communication parameters (such as communication protocol and baud rate) to enable normal data communication with external systems and devices.

[0065] (4) Data communication and interaction:

[0066] Based on the configuration of the main chip 4, communication module 5 establishes a communication connection with external systems (such as the monitoring center of a new energy wind farm, other control equipment, etc.). If the RS485 protocol is used, communication module 5 transmits data according to the corresponding electrical standards and data formats; if the Ethernet protocol is used, it interacts with external network devices through the network interface. External devices (such as sensors, other control devices, etc.) can communicate with the device through serial port 6. Serial port 6 receives serial data sent by external devices and transmits it to the main chip 4 of the control board 3 for processing; the main chip 4 can also send control commands to external devices through serial port 6.

[0067] (5) Circuit stability control:

[0068] The main chip 4 receives data from the communication module 5 and serial port 6 to obtain real-time operating parameters (such as voltage, current, frequency, etc.) and external control commands of the wind farm circuit. Based on preset control strategies and algorithms, the main chip 4 analyzes and processes the acquired data to determine whether the wind farm circuit is in a stable operating state. If an abnormality occurs in the circuit (such as excessively high or low voltage, current overload, etc.), the main chip 4 controls the relays, contactors, and other components inside the control circuit module 7 to perform rapid switching and protection operations. For example, when a current overload is detected, the main chip 4 controls the relay to disconnect the circuit to prevent equipment damage; when the circuit returns to normal, the main chip 4 controls the relay to re-close the circuit, restoring normal power supply.

[0069] (6) Installation and adjustment of the device:

[0070] During installation, the opening and closing state of the clamping ring 16 can be changed by adjusting the hinge pin 17 on the clamping ring 16, facilitating the installation of the device in a suitable location (such as on a support structure in a wind farm). Using the adjusting bolt 20 inside the connecting frame 19 and the adjusting nut 21 fitted onto the adjusting bolt 20, the position of the adjusting bolt 20 can be adjusted by rotating the adjusting nut 21, thereby adjusting the height and angle of the connecting frame 19 to adapt to different installation requirements. By rotating the fastening bolt 12, the tightness of the clamping sleeve is adjusted to ensure that the locking frame 11 and the locking seat 10 are firmly fixed, preventing displacement during operation.

[0071] (7) Equipment maintenance and repair:

[0072] Regularly inspect the device to check the working status of each component, including whether the output voltage of power module 2 is stable, whether the indicator lights on control board 3 are displaying normally, and whether the communication connection of communication module 5 is stable. When the device malfunctions, fault information can be obtained through the fault diagnosis function on control board 3 or external devices (such as diagnostic tools connected via serial port 6) to locate the faulty component. For components that need to be replaced, such as damaged relays or contactors, first disconnect the main switch 8 to ensure that the device is powered off, then disassemble the faulty component in the reverse order of installation, install the new component, and perform necessary debugging and testing to ensure that the device returns to normal operation.

[0073] The new energy wind farm circuit stability control device provided in this application has the following beneficial effects:

[0074] (1) Improve circuit stability:

[0075] This device integrates key components such as control box 1, power module 2, control board 3, main chip 4, communication module 5, serial port 6, and circuit module 7 to form a highly integrated control system. The fixed connections and rational layout between the modules effectively reduce interference in signal transmission and ensure stable circuit operation. In particular, the placement of main chip 4 in the central area of ​​control board 3 optimizes the signal processing path, further improving the system's response speed and stability.

[0076] (2) Enhance anti-interference capability:

[0077] The control box 1 is externally equipped with a base 9 and a locking structure, which includes a locking seat 10 and a locking frame 11. The locking seat 10 and locking frame 11 can adopt an arc-shaped design, which not only provides good mechanical support, but also reduces electromagnetic interference from the external environment to the internal circuit through its unique arc shape design.
