Description

Technical Field

[0001] This invention belongs to the field of power electronics technology, specifically a photovoltaic inverter component with fault early warning function. Background Technology

[0002] In the field of photovoltaic energy, the photovoltaic inverter, as the core equipment that converts the direct current of photovoltaic modules into alternating current, directly determines the power generation efficiency and safety of the photovoltaic power generation system based on its operational reliability.

[0003] However, traditional photovoltaic inverter fault monitoring and early warning technologies have many shortcomings, which constitute the background technical pain points of this component's development. Specifically, these are as follows: Existing monitoring methods are limited by manual inspection, which is inefficient and lagging. In the early days, fault diagnosis of photovoltaic inverters mainly relied on regular manual inspections. Maintenance personnel had to check the voltage, current, temperature and other parameters of each device. This method not only consumed a lot of manpower and resources, but also had a significant lag in fault detection. Often, the fault was only detected after the equipment had already failed or its performance had severely degraded, resulting in power generation losses and a sharp increase in equipment maintenance costs. Single sensor monitoring lacked dimension. Some traditional inverters were only equipped with simple temperature or current sensors, which could only monitor local parameters. However, the causes of photovoltaic inverter faults are complex, involving multiple dimensions such as abnormal electrical parameters, thermal management failure, and mechanical aging. A single sensor cannot achieve comprehensive fault early warning and is prone to missed or false diagnoses.

[0004] In summary, existing photovoltaic inverter fault early warning technologies have significant shortcomings in terms of monitoring efficiency, dimensional coverage, scenario adaptability, intelligent prediction, and environmental stability, and cannot meet the photovoltaic industry's needs for preventive maintenance, full-dimensional monitoring, and low-cost operation and maintenance. Therefore, there is an urgent need for a photovoltaic inverter fault early warning component that integrates multiple sensors, is flexibly adjustable, and has intelligent prediction capabilities to solve the above-mentioned industry pain points. This is the core background and driving force behind the development of this component. Summary of the Invention

[0005] To overcome the shortcomings of existing technologies and solve the technical problem of photovoltaic inverter components with fault early warning functions mentioned in the background art, the technical solution adopted by this invention is as follows: The photovoltaic inverter component with fault early warning function of this invention includes a monitoring box. A slide is fixedly connected to the inner side wall of the monitoring box. A placement frame is slidably fitted in the middle of the slide. The placement frames are evenly distributed in the middle of the slide. Laser sensors are placed on the inner side walls of two placement frames. A data transmission line is connected to one end of each laser sensor. The other end of the data transmission line is connected to a control terminal. A sliding groove is opened on the top of the monitoring box. The sliding groove is evenly distributed on the top of the monitoring box. A fixing frame is fixedly connected to the side wall of the laser sensor. The fixing frame and the sliding groove are in a sliding fit. A control plate is fixedly connected to the end of the fixed frame, a limit component is provided on the side wall of the slide, an adjustment component is provided at the bottom of the monitoring box, and a dustproof component is slidably fitted on the side wall of the monitoring box. Through the above structure, the monitoring position of the laser sensor can be flexibly adjusted. The monitoring point of the laser sensor can be precisely adjusted according to the layout of different modules of the photovoltaic inverter, solving the problem of poor adaptability of traditional fixed-installation sensors. At the same time, the data transmission line is directly connected to the control terminal to realize the real-time transmission of monitoring data, providing raw data support for fault early warning algorithms. The integration of the limit component, adjustment component, and dustproof component further ensures the stable operation and long-term reliability of the equipment in complex outdoor environments, ultimately achieving adaptable, high-precision, and real-time fault monitoring capabilities.

[0006] Preferably, the limiting component includes limiting holes, and both the slide and the placement frame have limiting holes on their side walls. The limiting holes are evenly distributed on the side walls of the slide, and the limiting frame slides and engages in the middle of the limiting holes. Through the above structure, the placement frame and the laser sensor are quickly positioned and securely locked. During the operation of the photovoltaic inverter, equipment vibration may cause the sensor to shift. The limiting component, through its mechanical locking structure, can prevent the monitoring point from shifting, ensuring that the laser sensor is always aligned with the target monitoring area. This solves the problem of decreased monitoring accuracy during dynamic operation and ensures the accuracy of fault warning data.

[0007] Preferably, the adjustment component includes a rotating base, which is fixedly connected to the bottom of the monitoring box. A telescopic rod is rotatably fitted to the middle of the rotating base, and a base plate is fixedly connected to the bottom of the telescopic rod. A reinforcement component is provided on the side wall of the telescopic rod. Through the above structure, the height and angle of the monitoring box are adjustable in both directions: the telescopic rod can be extended and retracted to adapt to different installation scenarios, and the monitoring angle of the laser sensor can be adjusted by rotating the rotating base. This design breaks through the spatial limitations of traditional fixed installation, ensuring that the sensor can cover the key fault risk points of the inverter in different installation environments, and improving the coverage of fault early warning.

[0008] Preferably, the reinforcement component includes reinforcing ribs, the sidewall of the telescopic rod is fixedly connected to the reinforcing ribs, the end of the reinforcing ribs is fixedly connected to the top of the base plate, and the bottom of the base plate is fixedly connected to anti-slip pads. The anti-slip pads are evenly distributed on the bottom of the base plate. Through the above structure, the overall structure of the equipment is made resistant to overturning and anti-slip stability. Photovoltaic inverters are mostly installed outdoors and are easily affected by wind, rain and vibration. The reinforcing ribs can resist external impact by enhancing the connection strength between the telescopic rod and the base plate, while the anti-slip pads prevent the equipment from sliding on slopes or smooth surfaces by increasing friction. This design solves the problem of insufficient equipment stability in complex outdoor environments and ensures the continuous reliability of the monitoring system during long-term operation.

[0009] Preferably, a mounting base is fixedly connected to the outer wall of the monitoring box, and a temperature sensor is slidably fitted onto the inner wall of the mounting base. Through the above structure, convenient monitoring of temperature parameters and rapid maintenance of the sensor are realized. Temperature is a core early warning parameter for photovoltaic inverter faults. The temperature sensor can collect the ambient temperature of the inverter casing or internal environment in real time, supplementing the optical monitoring data of the laser sensor. The sliding fit design allows for quick removal and replacement of the sensor, solving the problem of cumbersome maintenance of traditional fixed-installation sensors, ensuring the continuity of temperature monitoring, and improving the comprehensiveness of fault early warning.

[0010] Preferably, the dustproof component includes a dustproof plate, which is slidably fitted onto the side wall of the monitoring box. A pull ring is fixed to the side wall of the dustproof plate. Through the above structure, a balance is achieved between dust protection and convenient maintenance inside the monitoring box. The operating environment of photovoltaic inverters is dusty, and dust adhering to the laser sensor lens or circuit can lead to a decrease in monitoring accuracy. The dustproof plate can isolate external dust, while the pull ring allows for quick opening and closing, facilitating regular cleaning of the sensor or maintenance of internal components. This design solves the contradiction between protection and maintenance, protecting precision components without affecting daily operation and maintenance, and extending the service life of the equipment.

[0011] Preferably, a telescopic protractor is installed at the bottom of the rotating seat. Through the above structure, the angle adjustment of the monitoring box is precisely controllable. The monitoring accuracy of the laser sensor is directly related to the angle. The telescopic protractor can quantify the rotation angle of the rotating seat through scale markings, ensuring that the sensor can be aligned with the preset monitoring point under different installation scenarios. This design solves the problem of low accuracy due to experience in angle adjustment, improves the consistency of monitoring data, and provides more reliable input for fault early warning algorithms.

[0012] The beneficial effects of this invention are as follows:

[0013] 1. The photovoltaic inverter module with fault early warning function described in this invention, through the structural arrangement of a sliding frame, a placement frame, and a fixed frame, enables flexible adjustment of the laser sensor monitoring position. The monitoring point of the laser sensor can be precisely adjusted according to the layout of different modules of the photovoltaic inverter, solving the problem of poor adaptability of traditional fixed-installation sensors. Simultaneously, the data transmission line directly connects to the control terminal, enabling real-time transmission of monitoring data and providing raw data support for the fault early warning algorithm. The integration of limit components, adjustment components, and dustproof components further ensures the stable operation and long-term reliability of the equipment in complex outdoor environments, ultimately achieving adaptable, high-precision, and real-time fault monitoring capabilities.

[0014] 2. The photovoltaic inverter component with fault early warning function described in this invention achieves rapid positioning and stable locking of the placement rack and laser sensor through the structural arrangement of limiting holes, limiting frames and rotating seats. During the operation of the photovoltaic inverter, equipment vibration may cause sensor displacement. However, the limiting component, through a mechanical locking structure, can prevent the monitoring point from shifting, ensuring that the laser sensor is always aligned with the target monitoring area. This solves the problem of decreased monitoring accuracy during dynamic operation and ensures the accuracy of fault early warning data. Attached Figure Description

[0022] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0023] Specific implementation examples are given below.

[0024] like Figures 1 to 2As shown in the embodiment of the present invention, a photovoltaic inverter assembly with fault early warning function includes a monitoring box 1. A slide 11 is fixedly connected to the inner wall of the monitoring box 1. A placement frame 12 is slidably fitted in the middle of the slide 11. The placement frames 12 are evenly distributed in the middle of the slide 11. Laser sensors 13 are placed on the inner walls of the two placement frames 12. A data transmission line 14 is connected to one end of each laser sensor 13, and the other end of the data transmission line 14 is connected to a control terminal. A sliding groove 16 is formed on the top of the monitoring box 1, and the sliding grooves 16 are evenly distributed on the top of the monitoring box 1. A fixing frame 15 is fixedly connected to the side wall of each laser sensor 13. The fixed frame 15 and the slide groove 16 are in sliding fit. A control plate 17 is fixedly connected to the end of the fixed frame 15. A limit component is provided on the side wall of the slide 11. An adjustment component is provided at the bottom of the monitoring box 1. A dustproof component is slidably fitted on the side wall of the monitoring box 1. During operation, the monitoring box 1 is the core shell structure of the photovoltaic inverter fault early warning system. The slide 11 is fixed to its inner side wall by welding or bolts. The slide 11 is long and has a slide groove in the middle for the placement frame 12 to slide in fit. The placement frame 12 consists of two symmetrical clamping structures, evenly distributed along the length of the middle of the slide 11. The inner side walls of the two placement frames 12 share a common... A laser sensor 13 is clamped and placed. The end of the laser sensor 13 is connected to a data transmission line 14 via a terminal block. The other end of the data transmission line 14 is connected to the control terminal of the photovoltaic inverter. A sliding groove 16, corresponding to the position of the slide bracket 11, is provided on the top of the monitoring box 1. The sliding groove 16 is evenly distributed along the length of the monitoring box 1. A fixing frame 15 is bolted to the side wall of the laser sensor 13. The protruding part of the fixing frame 15 slides in conjunction with the sliding groove 16. A control plate 17 is integrally formed or bolted to the end of the fixing frame 15. The operator can push the control plate 17 to move the fixing frame 15 and the laser sensor 13 along the sliding groove 16 and the slide bracket 11. To achieve adjustment of the monitoring position of the laser sensor 13, a limiting component is provided on the side wall of the slide 11 to fix the position of the placement frame 12, and an adjustment component is provided at the bottom of the monitoring box 1 to adjust the overall height and angle. The side wall of the monitoring box 1 slides in conjunction with a dustproof component to isolate dust. This step can achieve flexible adjustment of the monitoring position of the laser sensor 13 through the sliding cooperation structure of the slide 11, placement frame 12, fixing frame 15 and slide groove 16, adapting to the monitoring needs of photovoltaic inverters of different specifications. The coordinated design of the limiting component, adjustment component and dustproof component not only ensures the stability of the component operation, but also achieves the accuracy of fault early warning and the ease of equipment maintenance.

[0025] like Figure 2As shown, the limiting component includes limiting holes 2. Limiting holes 2 are provided on the side walls of both the slide 11 and the placement frame 12. The limiting holes 2 are evenly distributed on the side walls of the slide 11. A limiting frame 21 slides and engages in the middle of each limiting hole 2. During operation, the limiting component consists of the limiting holes 2 and the limiting frame 21. Multiple limiting holes 2 are provided on the side walls of both the slide 11 and the placement frame 12, and are evenly distributed along the length of the side walls of the slide 11. When the placement frame 12 moves the laser sensor 13 to the target position, the limiting frame 21 is inserted into the limiting holes 2 aligned with the slide 11 and the placement frame 12, thus axially fixing the placement frame 12. This step is simple and reliable due to the engaging structure of the limiting holes 2 and the limiting frame 21, allowing for quick locking of the placement frame 12 and preventing the laser sensor 13 from shifting due to vibration during operation, ensuring the continuity and accuracy of fault monitoring.

[0026] like Figure 4 As shown, the adjustment assembly includes a rotating seat 3. The rotating seat 3 is fixedly connected to the bottom of the monitoring box 1.

A reinforcement assembly is provided on the side wall of the telescopic rod 31. During operation, the adjustment assembly includes the rotating seat 3, the telescopic rod 31, and the base plate 32. The rotating seat 3 is fixedly connected to the bottom of the monitoring box 1 by bolts. The middle of the rotating seat 3 is rotatably connected to the telescopic rod 31 through a bearing, so that the monitoring box 1 can rotate around the axis of the telescopic rod 31. The telescopic rod 31 is a multi-section telescopic structure. The base plate 32 is fixedly connected to the bottom by welding. The height of the monitoring box 1 can be adjusted by stretching or contracting the telescopic rod 31. This step utilizes the rotational connection between the rotating seat 3 and the telescopic rod 31, and the telescopic structure of the telescopic rod 31, so that the height and angle of the monitoring box 1 can be flexibly adjusted, which can adapt to different installation scenarios and monitoring angles, and improve the coverage of fault early warning.

[0027] like Figure 2 As shown, the reinforcing component includes reinforcing ribs 4. Reinforcing ribs 4 are fixedly connected to the side wall of the telescopic rod 31. The ends of the reinforcing ribs 4 are fixedly connected to the top of the base plate 32. Anti-slip pads 41 are fixedly connected to the bottom of the base plate 32 and are evenly distributed on the bottom of the base plate 32. During operation, the reinforcing component includes reinforcing ribs 4 and anti-slip pads 41. Multiple reinforcing ribs 4 are fixedly welded to the side wall of the telescopic rod 31. The ends of the reinforcing ribs 4 are welded and fixed to the top of the base plate 32. Anti-slip pads 41, made of rubber, are evenly distributed on the bottom of the base plate 32. This step significantly improves the connection strength between the telescopic rod 31 and the base plate 32 through the setting of reinforcing ribs 4, preventing the component from tipping over due to load or external force. The anti-slip pads 41 enhance the friction between the base plate and the mounting surface, further improving overall stability and ensuring long-term reliable operation of the equipment.

[0029] like Figure 2 As shown, the dustproof assembly includes a dustproof plate 6, which is slidably fitted onto the side wall of the monitoring box 1. A pull ring 61 is fixedly connected to the side wall of the dustproof plate 6. During operation, the dustproof assembly includes the dustproof plate 6 and the pull ring 61.

The dustproof plate 6 is slidably fitted onto the inner side wall of the opening, such as by using a guide rail slider structure. The pull ring 61 is fixedly connected to the side wall of the dustproof plate 6 by welding. The operator can open and close the dustproof plate 6 by pulling the pull ring 61. This step allows the dustproof plate 6 to effectively prevent external dust from entering the monitoring box 1, protecting precision components such as laser sensors and control circuits, and extending the service life of the equipment. The pull ring 61 makes the dustproof plate easy to operate and does not affect the daily maintenance and troubleshooting of the equipment.

[0030] like Figure 2 As shown, a telescopic protractor 7 is installed at the bottom of the rotating base 3. During operation, the telescopic protractor 7 is bolted to the bottom of the rotating base 3. The protractor is a telescopic fan-shaped structure with angle scale markings. When adjusting the rotation angle of the telescopic rod 31, the angle range can be precisely controlled through the scale of the telescopic protractor 7. This step allows the setting of the telescopic protractor 7 to make the angle adjustment of the telescopic rod 31 more precise, ensuring that the monitoring direction of the laser sensor 13 is completely aligned with the area to be monitored by the photovoltaic inverter, greatly improving the accuracy and response speed of fault warning.

[0031] During operation, the monitoring box 1 serves as the core outer shell structure of the photovoltaic inverter fault early warning system. Its inner wall is fixed with a slide 11 by welding or bolts. The slide 11 is elongated and has a groove in the middle for the placement frame 12 to slide in. The placement frame 12 consists of two symmetrical clamping structures evenly distributed along the length of the slide 11. The inner walls of the two placement frames 12 together clamp and hold the laser sensor 13. The end of the laser sensor 13 is connected to a data transmission line 14 via a terminal block. The other end of the data transmission line 14 is connected to the control terminal of the photovoltaic inverter. The top of the monitoring box 1 has a groove 16 corresponding to the position of the slide 11, evenly distributed along the length of the monitoring box 1. The sidewall of the laser sensor 13 is fixed with a mounting bracket 12 by bolts. The fixed frame 15 has a protruding part that slides into the slide groove 16. A control plate 17 is integrally formed or bolted to the end of the fixed frame 15. The operator can push the control plate 17 to move the fixed frame 15 and the laser sensor 13 along the slide groove 16 and the slide 11, thereby adjusting the monitoring position of the laser sensor 13. A limiting component is provided on the side wall of the slide 11 to fix the position of the placement frame 12. An adjustment component is provided at the bottom of the monitoring box 1 to adjust the overall height and angle.

This step allows for flexible adjustment of the monitoring position of the laser sensor 13 through the sliding engagement structure of the slide 11, placement frame 12, fixed frame 15, and slide groove 16, adapting to the monitoring needs of different specifications of photovoltaic inverters. The coordinated design of the limiting component, adjusting component, and dustproof component ensures the stability of component operation, while also achieving accurate fault warning and easy maintenance of the equipment. The limiting component consists of limiting holes 2 and limiting brackets 21. Multiple limiting holes 2 are provided on the side walls of both the slide 11 and the placement bracket 12. The limiting holes 2 are evenly distributed along the length of the side wall of the slide 11. After the placement bracket 12 moves the laser sensor 13 to the target position, the limiting bracket 21 is inserted into the limiting holes 2 aligned with the slide 11 and the placement bracket 12 to achieve axial fixation of the placement bracket 12. This step is simple and reliable due to the cooperation structure of the limiting holes 2 and the limiting bracket 21, which can quickly lock the position of the placement bracket 12 and prevent the laser sensor 13 from shifting due to vibration during operation. To ensure the continuity and accuracy of fault monitoring, the adjustment assembly includes a rotating base 3, a telescopic rod 31, and a base plate 32. The rotating base 3 is bolted to the bottom of the monitoring box 1. The middle part of the rotating base 3 is rotatably engaged with the telescopic rod 31 via a bearing, allowing the monitoring box 1 to rotate around the axis of the telescopic rod 31. The telescopic rod 31 is a multi-section telescopic structure, and the base plate 32 is welded to its bottom. The height of the monitoring box 1 can be adjusted by stretching or retracting the telescopic rod 31. This step utilizes the rotational engagement between the rotating base 3 and the telescopic rod 31, as well as the telescopic structure of the telescopic rod 31, to flexibly adjust the height and angle of the monitoring box 1, adapting to different installation scenarios and monitoring angles, and improving the coverage of fault early warning.

The anti-slip pads 41 enhance the friction between the base plate and the mounting surface, further improving overall stability and ensuring long-term reliable operation of the equipment. A mounting base 5 is bolted to the outer wall of the measuring box 1. The mounting base 5 is a rectangular groove structure with a sliding groove on its inner side wall. The housing of the temperature sensor 51 slides in this sliding groove, allowing the temperature sensor 51 to be installed and removed by pulling it along the groove. This sliding fit design between the mounting base 5 and the temperature sensor 51 makes the installation, removal, and maintenance of the temperature sensor more convenient, allows for quick replacement of faulty sensors, ensures continuous temperature monitoring, and provides reliable data support for thermal fault early warning of photovoltaic inverters. The dustproof component includes a dustproof... The dustproof plate 6 and pull ring 61 are provided. A rectangular opening is provided on the side wall of the monitoring box 1.

The pull ring 61 makes the dustproof plate easy to operate and does not affect daily maintenance and troubleshooting. A telescopic protractor 7 is bolted to the bottom of the rotating seat 3. This protractor is a telescopic fan-shaped structure with angle markings. When adjusting the rotation angle of the telescopic rod 31, the angle range can be precisely controlled through the scale of the telescopic protractor 7.
