[0002] With the popularization of photovoltaic power generation technology, the issue of cleaning photovoltaic modules has become increasingly prominent. Dust, bird droppings, snow, and other contaminants can reduce the power generation efficiency of photovoltaic modules. Currently, common cleaning methods include manual wiping, vehicle-mounted cleaning trucks, and fixed cleaning systems.

[0003] A photovoltaic panel cleaning device, with Chinese patent number CN220190806U, is described. This device includes a photovoltaic panel fixing frame to secure the photovoltaic panel to the device, preventing it from falling and breaking during cleaning. It also includes a second motor, an electric telescopic rod, and a sleeve, which automatically extend and retract according to the length of the photovoltaic panel to drive the roller brush to scrub the surface of the photovoltaic panel. The device is simple to operate, has low manufacturing cost, saves a lot of labor, and has a good cleaning effect.

[0004] Existing fixed-installation cleaning systems typically have their nozzles located on the sides or bottom of the photovoltaic array. When spraying water from the sides, the water flow is difficult to cover the entire surface of the panel, especially on the side furthest from the nozzle, which can easily create cleaning dead zones. Utility Model Content

[0005] To address the shortcomings of existing technologies, this invention provides a rotating nozzle at the top of a photovoltaic array, which solves the problems mentioned in the background section.

[0006] To achieve the above objectives, this utility model is implemented through the following technical solution: a top rotating nozzle for a photovoltaic array, comprising a photovoltaic panel, a frame fixedly connected to the outer end of the photovoltaic panel, and sliding grooves fixedly connected to the upper and lower ends of the inclined frame, with lead screws rotatably connected in both sliding grooves, a slider threaded onto the lead screw, a support plate fixedly connected to the top of the slider, a connecting rod fixedly connected to the top of the support plate, an adjustable rotating nozzle mounted on the top of the connecting rod, a bracket fixedly connected to the side end of the frame, a servo motor fixedly connected to the bracket, and the output end of the servo motor connected to one of the lead screws, with belt pulleys sleeved on the surfaces of both lead screws, and the two belt pulleys connected by a belt.

[0007] As a further technical solution of this utility model, a support plate is fixedly connected to the bottom of the chute, and a self-rebound winding shaft is installed on the support plate. A connecting wire is wound inside the self-rebound winding shaft, and the connecting wire extends to the outside of the self-rebound winding shaft and is electrically connected to the rotating nozzle.

[0008] As a further technical solution of this utility model, a movable rod is slidably connected to the top of the connecting rod, and a conveying pipe is fixedly connected to the bottom of the rotating nozzle, and the conveying pipe passes through the movable rod and extends to the outside of the connecting rod.

[0009] As a further technical solution of this utility model, a suction pump is connected to the end of the delivery pipe away from the rotating nozzle, and the input end of the suction pump is connected to a water tank through a water pipe.

[0010] As a further technical solution of this utility model, an electromagnetic block is sleeved on the surface of the connecting rod near the rotating nozzle, and a magnetic plate sleeved on the surface of the movable rod is fixedly connected to the bottom of the rotating nozzle, and the magnetic plate and the electromagnetic block are magnetically attracted to each other.

[0011] As a further technical solution of this utility model, the sliding groove located above the photovoltaic panel has the same tilt angle as the photovoltaic panel, and the sliding groove located below the panel is perpendicular to the ground.

[0012] As a further technical solution of this utility model, a controller for controlling the suction pump, electromagnetic block, servo motor and rotating nozzle is fixedly connected to the slide.

[0013] This invention provides a rotating nozzle at the top of a photovoltaic array, which has the following advantages compared with the prior art:

[0014] This design features a rotating nozzle on the top of a photovoltaic array. A controller activates a servo motor to drive one of the lead screws, which in turn rotates the upper and lower lead screws synchronously via a belt pulley and belt. This drives sliders on the two lead screws to move the rotating nozzle horizontally back and forth. During this movement, a suction pump is activated, delivering water to the rotating nozzle through a delivery pipe. The rotating nozzle itself is connected to a power source via an electrical wire and can rotate while moving, achieving comprehensive, maximum-area cleaning of the photovoltaic panel surface. Furthermore, the rotating nozzle's movement causes a self-returning rewind shaft to rotate, extending the electrical wire. When the rotating nozzle returns to its original position, the electrical wire automatically rewinds via the self-returning rewind shaft, effectively storing the wire. This invention, by providing a horizontally reciprocating rotating nozzle on both the upper and lower inclined sides of the photovoltaic panel, allows for cyclical movement and comprehensive cleaning of the photovoltaic panel surface, avoiding any blind spots.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0021] Please see Figures 1-2 This utility model provides a technical solution for a top rotating nozzle of a photovoltaic array: it includes a photovoltaic panel 1, a frame 18 fixedly connected to the outer end of the photovoltaic panel 1, a sliding groove 2 fixedly connected to the upper and lower ends of the inclined frame 18, a lead screw 3 rotatably connected in each of the two sliding grooves 2, a slider 15 threadedly connected to the lead screw 3, a support plate 4 fixedly connected to the top of the slider 15, a connecting rod 6 fixedly connected to the top of the support plate 4, an adjustable rotating nozzle 5 installed at the top of the connecting rod 6, a bracket 9 fixedly connected to the side end of the frame 18, a servo motor 10 fixedly connected to the bracket 9, and the output end of the servo motor 10 connected to one of the lead screws 3, and belt pulleys 17 sleeved on the surfaces of the two lead screws 3, and the two belt pulleys 17 are connected to each other by a belt 16;

[0022] Please see Figure 3 A support plate 19 is fixedly connected to the bottom of the chute 2. A self-rebound rewinding shaft 11 is installed on the support plate 19. A connecting wire 12 is wound inside the self-rebound rewinding shaft 11 and extends to the outside of the self-rebound rewinding shaft 11 to be electrically connected to the rotating nozzle 5. A movable rod 14 is slidably connected to the top of the connecting rod 6. A conveying pipe 13 is fixedly connected to the bottom of the rotating nozzle 5 and passes through the movable rod 14 and extends to the outside of the connecting rod 6. A suction pump is connected to the end of the conveying pipe 13 away from the rotating nozzle 5, and a water tank is connected to the input end of the suction pump through a water pipe.

[0023] Please see Figure 4An electromagnetic block 7 is fitted on the surface of the connecting rod 6 near the rotating nozzle 5. A magnetic plate 8 is fixedly connected to the bottom of the rotating nozzle 5 and fitted on the surface of the movable rod 14. The magnetic plate 8 and the electromagnetic block 7 are magnetically attracted to each other. The slide 2 located above the photovoltaic panel 1 has the same tilt angle as the photovoltaic panel 1. The slide 2 located below is perpendicular to the ground. A controller for controlling the suction pump, the electromagnetic block 7, the servo motor 10 and the rotating nozzle 5 is fixedly connected to the slide 2.

[0024] The working principle of this utility model is as follows: The servo motor 10 is activated by the controller to drive one of the lead screws 3 to rotate. This, in turn, drives the upper and lower lead screws 3 to rotate synchronously via the belt pulley 17 and belt 16. This, in turn, drives the sliders 15 on the two lead screws 3 to move the rotating nozzle 5 horizontally back and forth. During this movement, a suction pump is activated, and water is delivered to the rotating nozzle 5 through the delivery pipe 13 for spraying. The rotating nozzle 5 itself is connected to a power source via the connecting wire 12 and can rotate during movement, thus achieving comprehensive and maximum area spraying of the photovoltaic panel 1 surface. However, the rotating nozzle 5... When the rotating nozzle 5 is in motion, it drives the self-rebound rewinding shaft 11 to rotate and connect the wire 12 to be extended. When the rotating nozzle 5 returns to its original position, the wire 12 is automatically rewound by the self-rebound rewinding shaft 11. The wire 12 plays a storage role. When it is necessary to change the water pressure and area of ​​the spray, the controller can activate the electromagnetic block 7 to magnetically attract the magnetic plate 8, moving the rotating nozzle 5 downward. This allows the rotating nozzle 5 to get closer to the surface of the photovoltaic panel 1, reducing the spray area. After the distance to the photovoltaic panel 1 is shortened, the water jet force sprayed on the surface of the photovoltaic panel 1 becomes greater, which can wash off firmly adhered dirt.

It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model.
