Description

Technical Field

[0001] This invention relates to the field of photovoltaic panel cleaning technology, specifically to a photovoltaic power station operation and maintenance device and its usage method. Background Technology

[0002] As a crucial component of renewable energy, photovoltaic (PV) power generation has experienced rapid development globally in recent years. With the continuous growth of PV power plant installed capacity, the demand for operation and maintenance (O&M) management has also increased. Traditional O&M models rely on manual inspections and operations, resulting in low efficiency, safety hazards, and high maintenance costs. For example, in large-scale PV power plants, PV modules are densely distributed, and conventional tools (such as climbing ladders and handheld testing instruments) are insufficient for efficient maintenance. Furthermore, relying on manual recording and judgment can easily lead to data errors and missed faults. In addition, PV modules are exposed to the outdoor environment for extended periods, making them susceptible to pollution, aging, or microcracks that can affect power generation efficiency. Therefore, intelligent and automated methods are urgently needed to improve O&M quality.

[0003] While existing photovoltaic (PV) operation and maintenance (O&M) equipment encompasses basic tools and some intelligent systems, it still faces numerous limitations. On one hand, traditional lifting tools (such as scaffolding and aerial work platforms) lack flexibility and are ill-suited to different terrains and array heights. On the other hand, data acquisition and analysis systems primarily focus on macroscopic power generation monitoring, lacking the ability to accurately locate component-level defects. Furthermore, the portability and storage management of O&M tools also have shortcomings; for example, the dispersed nature of tools and the ease with which consumables can be lost reduce on-site operational efficiency. Summary of the Invention

[0004] To address existing problems, this invention provides a photovoltaic power station operation and maintenance device and its usage method. Through the modular design of the lifting mechanism and cleaning mechanism, combined with camera recognition linked to the camera and controller, and the user-friendly design of the moving wheels and storage drawers, it effectively improves the efficiency, accuracy and economy of photovoltaic panel cleaning and maintenance, and significantly improves the overall efficiency of power station operation and maintenance.

[0005] To achieve the above objectives, the present invention provides the following technical solution.

[0006] This invention provides a photovoltaic power station operation and maintenance device, including a base mechanism, a lifting mechanism, a placement plate, and a cleaning mechanism. The placement plate is connected to the base mechanism via the lifting mechanism and is used for cleaning and maintaining photovoltaic panels. A gantry sliding groove is provided on both sides of the placement plate. The cleaning mechanism includes a cleaning screw, a cleaning motor, a gantry, a scanning camera, and a cleaning brush rod. The scanning camera is located on the side of the gantry, and the cleaning brush rod is located at the bottom. Slider blocks or rollers are located at the bottom of both sides, corresponding to the gantry sliding groove. The gantry has an upper screw hole through which the cleaning screw passes. The cleaning screw is driven by the cleaning motor to move the gantry within the gantry sliding groove.

[0007] As a further improvement of the present invention, the gantry frame is provided with downward-facing cleaning fluid holes evenly arranged along its length direction, and multiple liquid hoses are provided inside the gantry frame, which are respectively connected to each cleaning fluid hole, for conveying cleaning fluid to each cleaning fluid hole.

[0008] As a further improvement of the present invention, a controller is also included, which is electrically connected to the scanning camera and the cleaning motor respectively, and is used to respond to the abnormal local area of ​​the photovoltaic panel captured by the scanning camera and move the gantry to the abnormal local position.

[0009] As a further improvement of the present invention, the lifting mechanism includes at least two fixed rods, two fixed rod sliding rings, four tension springs, four upper sliding rings, two slide rods, two sets of scissor bars, four lower sliding rings, two bidirectional lead screws, and two lifting motors. The placement plate has at least two fixed rod sliding grooves perpendicular to the sliding groove of the gantry frame. The fixed rods pass over the two fixed rod sliding grooves from above the placement plate. The two ends of the fixed rods pass through the fixed rod sliding grooves and connect to the fixed rod sliding rings below the placement plate. The fixed rod sliding rings are sleeved on the slide rods and connected to the tension springs. The tension springs are connected to the upper sliding rings and sleeved on the slide rods. The upper sliding rings are connected to the upper side of the scissor bars and the lower side of the scissor bars are connected to the lower sliding rings. The lower sliding rings are sleeved on the bidirectional lead screws, which are driven by the lifting motors.

[0010] As a further improvement of the present invention, the tension spring is sleeved on the slide rod.

[0011] As a further improvement of the present invention, a lower sliding ring limiting block is sleeved in the middle of the bidirectional lead screw.

[0012] As a further improvement of the present invention, the base mechanism includes a fixed plate and a base plate, with the fixed plate disposed on the base plate; the fixed plate is provided with lower lead screw holes corresponding to both ends of the bidirectional lead screw; and the base plate is provided with movable wheels.

[0013] As a further improvement of the present invention, the base mechanism also includes a storage drawer and a handle; the fixed plate is also provided with a storage drawer, and the storage drawer is provided with a handle.

[0014] As a further improvement of the present invention, a tie rod and a tie rod limiting block are provided on one side of the base plate.

[0015] This invention also discloses a method for using a photovoltaic power station operation and maintenance device, comprising the following steps: Move the base mechanism to the area of ​​the photovoltaic panels to be inspected and cleaned; Start the lifting mechanism to adjust the placement plate to a suitable height; start the cleaning mechanism, the cleaning screw rotates and drives the gantry frame to slide in the gantry frame sliding groove of the placement plate, while the scanning camera captures the condition of the photovoltaic panel surface; the cleaning brush rod at the bottom of the gantry frame cleans the photovoltaic panel as it slides with the gantry frame.

[0016] Compared with the prior art, the present invention has the following beneficial effects: This device combines a base mechanism, a lifting mechanism, a placement plate, and a cleaning mechanism. The placement plate can be adjusted in height with the help of the lifting mechanism, which can facilitate the inspection and cleaning of photovoltaic panels at different heights, improving the convenience and applicability of operation and maintenance. The cleaning mechanism drives the gantry to slide through a lead screw, realizing automatic cleaning of the photovoltaic panel surface. The scanning camera on the side of the gantry can capture the surface condition of the photovoltaic panel in real time, assisting in the detection of abnormal areas.

[0017] Preferably, the gantry frame is evenly provided with downward-facing cleaning fluid holes, and multiple liquid hoses are used to deliver the cleaning fluid to each cleaning fluid hole. When cleaning the photovoltaic panels, the cleaning fluid can be sprayed evenly at the same time, improving cleaning efficiency. The cleaning fluid helps to remove stains (such as bird droppings and algae) and improve the power generation efficiency of the photovoltaic panels.

[0018] Preferably, the controller is electrically connected to both the scanning camera and the cleaning motor, enabling it to respond to abnormal localities on the photovoltaic panel captured by the scanning camera and move the gantry crane to the location of the abnormality. This allows for quick and accurate location of the problem area on the photovoltaic panel, improving the response speed of operation and maintenance.

[0019] Preferably, a lifting motor drives a bidirectional lead screw, which in turn moves the lower sliding ring, thereby extending or retracting the scissor bar to adjust the height of the placement plate. This structure is relatively stable and reliable, capable of smoothly raising and lowering the placement plate, and has a strong load-bearing capacity, meeting the needs of maintenance tools and personnel of different weights. It is also compact, occupying little space; the tension spring and sliding rod structure distribute stress during lifting and lowering, extending the mechanical life.

[0020] Preferably, the tension spring is sleeved on the slide rod, which can make the movement of the tension spring more stable, prevent the tension spring from deviating or shaking during the extension and contraction process, improve the reliability and stability of the lifting mechanism, and extend the service life of the device.

[0021] Preferably, a lower sliding ring limiting block is sleeved in the middle of the bidirectional lead screw, which can limit the movement range of the lower sliding ring on the bidirectional lead screw, prevent the lower sliding ring from moving excessively and detaching from the bidirectional lead screw, and improve the safety and stability of the device.

[0022] Preferably, the base mechanism consists of a fixed plate and a base plate, with the fixed plate positioned on top of the base plate. The separate design of the fixed plate and the base plate enhances wind resistance and stability, making it particularly suitable for strong wind environments outdoors. The casters allow the base mechanism to be quickly moved to different photovoltaic panel areas.

[0023] Preferably, a storage drawer and handle are provided on the fixed plate to facilitate the storage of tools, accessories and other items used during maintenance and cleaning, to prevent tools from being scattered on site and to improve work efficiency.

[0024] Preferably, a pull rod and a pull rod limiting block are provided on one side of the base plate. When it is necessary to move the base mechanism, the pull rod facilitates short-distance dragging of the device, and the pull rod limiting block can lock the position to prevent slippage during operation.

[0025] This method automates the entire process from mobile device to cleaning completion, reducing the need for manual intervention and making it suitable for the operation and maintenance of large-scale photovoltaic power plants. Real-time camera feedback and gantry-based cleaning reduce repetitive work time and allow for a larger coverage area in a single maintenance operation. Attached Figure Description
