Description

Technical Field

[0001] This utility model relates to the field of operation and maintenance technology of new energy power plants, and specifically to a new energy power plant detection system. Background Technology

[0002] With the rapid development of new energy industries such as solar and wind power, the scale of new energy power plants is constantly expanding. The stable operation and power generation efficiency of power plants are directly related to the return on investment. Currently, the inspection of power plants mostly adopts manual inspection or fixed-point monitoring. Manual inspection suffers from low efficiency, high cost, strong subjectivity, and difficulty in detecting hidden defects; while fixed-point monitoring (such as infrared cameras installed in specific locations) has monitoring blind spots and cannot cover the entire power plant, especially for large power plants with complex terrain, making it difficult to achieve comprehensive and detailed inspection of each photovoltaic module.

[0003] Existing technologies include some track-based or mobile robot inspection solutions. However, in actual use, dust covering some photovoltaic modules makes it impossible to acquire clear images of the modules, making it difficult to determine their operating status. Furthermore, these modules cannot be cleaned in a timely manner during inspections, thus affecting the final inspection results. Utility Model Content

[0004] The purpose of this invention is to provide a new energy power plant testing system to solve the aforementioned problems existing in the current testing process for new energy power plants.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A new energy power plant inspection system includes a central control platform, a walking unit, a track unit, and an inspection unit. The track unit is erected above the photovoltaic module array of the photovoltaic power plant. The walking unit is mounted on the track unit and is configured to move along the track unit. The inspection unit is mounted on the walking unit. Both the walking unit and the inspection unit are communicatively connected to the central control platform. The inspection unit includes a moving component, a photovoltaic module cleaning component, a visible light camera, and an infrared thermal imager. The moving component is connected to the walking unit. The photovoltaic module cleaning component is mounted on the moving component and is used to drive the photovoltaic module cleaning component to move along the photovoltaic modules to clean them. The visible light camera and the infrared thermal imager are both mounted on the walking unit and are used to collect image information of the photovoltaic modules.

[0006] Furthermore, the walking unit includes a U-shaped mounting plate, walking wheels, and a drive motor. The walking wheels are disposed on the inner side of the U-shaped mounting plate, and multiple sets of walking wheels are arranged in a rectangular pattern along the length of the U-shaped mounting plate. The drive motor is connected to the walking wheels for transmission. The track unit includes an I-shaped track, and the walking wheels are used to support themselves on the I-shaped track. The drive motor is used to drive the walking wheels to move along the I-shaped track.

[0007] Furthermore, the moving component includes a Z-axis linear module and a Y-axis linear module. The Z-axis linear module is disposed on the U-shaped mounting plate in the vertical direction and extends downward. The Y-axis linear module is connected to the Z-axis linear module and is disposed in the horizontal direction. The photovoltaic module cleaning component is disposed on the Y-axis linear module. The Z-axis linear module is used to drive the Y-axis linear module to move vertically, and the Y-axis linear module is used to drive the photovoltaic module cleaning component to move horizontally.

[0008] Furthermore, the photovoltaic module cleaning assembly includes a connecting plate, an air knife, and an air storage tank. The connecting plate is mounted on the Y-axis linear module, the air knife is mounted on the lower side of the connecting plate and is inclined downwards, an L-shaped support plate is mounted on the U-shaped mounting plate, the air storage tank is mounted on the L-shaped support plate, and the air knife and the air storage tank are connected by pipelines.

[0009] Furthermore, the photovoltaic module cleaning assembly also includes a water spray pipe and a high-pressure water storage tank. The water spray pipe is disposed on the lower side of the connecting plate and is inclined downwards. The high-pressure water storage tank is disposed on the L-shaped support plate. The water spray pipe and the high-pressure water storage tank are connected by pipelines.

[0010] Furthermore, the top surface of the I-shaped track is connected to a column for supporting the I-shaped track. The column includes a vertical support rod and a horizontal support rod. The vertical support rod is inserted into the ground, and the horizontal support rod is disposed at the upper end of the vertical support rod and connected to the I-shaped track.

[0011] The beneficial effects of this utility model are: This invention integrates a movable cleaning component into the detection unit, enabling immediate cleaning of dirty photovoltaic modules during inspections. This ensures the clarity and accuracy of subsequent visible light and infrared image acquisition, fundamentally solving the problem of detection failure caused by dirt obstruction. The entire system is coordinated and controlled by a central control platform, automating the entire process of movement, cleaning, and image acquisition, significantly reducing manual intervention, improving inspection efficiency, and lowering long-term maintenance costs. It primarily uses air-knife dry cleaning, with optional high-pressure water washing to adapt to different cleaning needs. Driven by Z-axis and Y-axis linear modules, the cleaning component can precisely move to the area to be cleaned and perform reciprocating cleaning, providing comprehensive and targeted cleaning coverage.

Detailed Implementation

[0014] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0015] like Figures 1 to 3 As shown in the figure, this utility model embodiment provides a new energy power plant detection system, which mainly includes a central control platform, a walking unit 2, a track unit 3, and a detection unit. The central control platform is usually located in the control room of the power plant and includes a computer, server, control software, and communication module, used for planning inspection paths, sending control commands, receiving and storing, and analyzing detection data.

[0016] Figure 1As shown, the track unit 3 is erected above the photovoltaic module array of the photovoltaic power station via multiple columns 9, and spans the entire area to be tested. Figure 1 As shown, each column 9 includes a vertical support rod 91 and a horizontal support rod 92. The lower end of the vertical support rod 91 is fixed to the power station ground by anchor bolts or direct casting. The horizontal support rod 92 is welded or fixed to the top of the vertical support rod 91 by flanges, extending horizontally in a cantilever shape. The main body of the track unit 3 is an I-shaped track 31, the bottom of which is fixedly connected to the free end of the horizontal support rod 92 of each column 9 by bolts, thus forming a stable aerial corridor.

[0017] like Figure 1 and Figure 2 As shown, the traveling unit 2 is mounted on an I-shaped track 31. Specifically, the traveling unit 2 includes a U-shaped mounting plate 21 with an opening facing downwards. Multiple sets (e.g., four sets) of traveling wheels 22 are mounted on the front and rear sides of the inner wall of the U-shaped mounting plate 21 (along the track direction) via axles. The grooves of the traveling wheels 22 match the upper flange of the I-shaped track 31, allowing the traveling wheels 22 to roll smoothly on the I-shaped track 31. A drive motor 23 is also mounted on the U-shaped mounting plate 21. The drive motor 23 is connected to the axles of at least one set of traveling wheels 22 via a gear transmission mechanism (not shown in the figure) to provide power and drive all traveling wheels 22 to roll along the I-shaped track 31, thereby realizing the movement of the entire traveling unit 2.

[0018] The detection unit is mounted on the traveling unit 2 and moves with it. The core functional components of the detection unit are a visible light camera 7 and an infrared thermal imager 8, which are typically mounted on the front or bottom of the U-shaped mounting plate 21 via a pan-tilt unit or fixed bracket, with their lenses facing downwards towards the photovoltaic modules. The visible light camera 7 is used to capture images of the surface appearance of the photovoltaic modules, and the infrared thermal imager 8 is used to capture images of the infrared thermal distribution of the photovoltaic modules.

[0019] like Figure 2 and Figure 3 As shown, the moving component 5 includes a Z-axis linear module 51 and a Y-axis linear module 52. The fixed end of the Z-axis linear module 51 is vertically mounted in the middle of the U-shaped mounting plate 21, and its sliding block can move up and down in the vertical direction. The fixed end of the Y-axis linear module 52 is connected to the sliding block of the Z-axis linear module 51, so that the guiding direction of the Y-axis linear module 52 is horizontal (usually perpendicular to the track direction, i.e., along the width direction of the photovoltaic module). The height of the cleaning component can be adjusted by the Z-axis linear module 51 to adapt to photovoltaic module arrays with different installation tilt angles or height differences. The Y-axis linear module 52 can drive the cleaning component to move back and forth in the horizontal direction.

[0020] The photovoltaic module cleaning assembly 6 is installed at the end of the movable assembly 5. In this embodiment, the photovoltaic module cleaning assembly 6 preferably adopts an air-water mixed cleaning scheme. It includes a connecting plate 61, which is fixed to the sliding block of the Y-axis linear module 52. A wind knife 62 and a water spray pipe 64 are arranged side by side on the lower side of the connecting plate 61, both of which are mounted by adjustable-angle brackets, so that their air outlets and water outlets are tilted downwards and aimed at the surface of the photovoltaic module below.

[0021] An L-shaped support plate 24 is welded onto the U-shaped mounting plate 21. An air tank 63 and a high-pressure water tank 65 are fixedly mounted on the horizontal portion of the L-shaped support plate 24. The air tank 63 is connected to the air knife 62 via a high-pressure air pipe, and the high-pressure water tank 65 is connected to the water spray pipe 64 via a high-pressure water pipe. The air tank 63 and the high-pressure water tank 65 can be equipped with a small air compressor and water pump (not shown in the figure) for real-time pressurization, or they can be designed to be detachable for easy replenishment at the base station.

[0022] Work process: When the system begins its inspection, the central control platform controls the walking unit 2 to move along the I-shaped track 31 to the starting position of the first row of photovoltaic modules. First, the control system initiates the cleaning program. The Z-axis linear module 51 moves, lowering the connecting plate 61 and the air knife 62 and water spray pipe 64 below it to a suitable distance close to the surface of the photovoltaic modules. If necessary, the air knife 62 and / or the water spray pipe 64 are activated. High-pressure gas is ejected at high speed from the narrow slits of the air knife 62, forming an "air curtain" to blow away dust from the module surface; simultaneously, high-pressure water is atomized from the nozzles of the water spray pipe 64, wetting and rinsing away stubborn stains. During the cleaning process, the Y-axis linear module 52 is activated, driving the connecting plate 61 and its air knife 62 and water spray pipe 64 to reciprocate at a constant speed along the width of the photovoltaic module once or multiple times, ensuring that the cleaning covers the entire surface of the module. After cleaning, the Z-axis linear module 51 lifts the cleaned module back to its original position to avoid affecting subsequent inspections.

[0023] Next, the inspection procedure is initiated: the walking unit 2 moves precisely, aligning the visible light camera 7 and the infrared thermal imager 8 with the freshly cleaned photovoltaic module. The visible light camera 7 captures a high-resolution surface image to identify cracks, scratches, snail trails, and whether any obvious dirt remains. The infrared thermal imager 8 captures an infrared thermal image of the module. Since the surface has been cleaned, the thermal image accurately reflects the operating temperature of the internal cells, junction boxes, etc., thus accurately identifying defects such as hot spots, diode failures, and poor wiring connections.

[0024] All collected image data is transmitted back to the central control platform in real time via a wireless communication module for analysis, storage, and alarm functions. Then, the walking unit 2 moves to the next component to be inspected, repeating the "cleaning-inspection" process until all inspection tasks are completed. This invention organically combines automatic cleaning with optical detection, achieving an intelligent inspection process of "clean first, then diagnose," greatly improving the reliability of condition monitoring and the level of operation and maintenance management in new energy power plants.

[0025] Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model are within the protection scope of this utility model.
