Description

Technical Field

[0001] This application relates to the field of solar panel technology, and in particular to a solar panel cleaning system. Background Technology

[0002] Photovoltaic power generation is a technology that directly converts light energy into electrical energy using the photovoltaic effect at the semiconductor interface. Since solar panels are exposed to the elements for extended periods, dust easily accumulates on their surfaces. This dust not only reduces the amount of light radiation received by the photovoltaic modules, affecting system efficiency and power generation, but also causes hot spot effects, resulting in further power loss and impacting the lifespan of the photovoltaic modules. Therefore, it is necessary to clean the surface of the solar panels.

[0003] Using drones for cleaning can conveniently spray water to clean solar panels, but when the drone's water tank runs out, it takes a long time to refill it, requiring manual refilling and wasting manpower. Utility Model Content

[0004] The purpose of this section is to outline some aspects of the embodiments of this utility model and to briefly introduce some preferred embodiments. Some simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of this section, the abstract and the title of this utility model. Such simplifications or omissions shall not be used to limit the scope of this utility model.

[0005] In view of the problems existing in the prior art, the present invention is proposed.

[0006] A solar panel cleaning system for drone suspension, comprising a drone, the drone including a fuselage;

[0007] The drone is equipped with a spraying system, which includes a water tank that is detachably mounted on the bottom of the drone.

[0008] The water storage tank is equipped with an upward-facing water inlet;

[0009] The spraying system includes a water pumping pipe, which is located at the bottom of the machine body and is inserted into the water inlet.

[0010] It also includes a magnetic attraction system;

[0011] The magnetic attraction system includes a soft magnet disposed above the water storage tank;

[0012] The magnetic attraction system also includes a permanent magnet mechanism located at the bottom of the drone;

[0013] The permanent magnet mechanism adopts a Heilbeck permanent magnet mechanism, which includes a middle permanent magnet, two end permanent magnets and a yoke.

[0014] The yoke is positioned above the middle permanent magnet and the two end permanent magnets;

[0015] An electromagnetic induction coil is wound around the intermediate permanent magnet and the yoke. When the electromagnetic induction coil is energized, it generates a magnetic field that is opposite to that of the intermediate permanent magnet, and the magnetic force is not less than that of the intermediate permanent magnet.

[0016] The electromagnetic induction coil is connected to the power supply of the drone;

[0017] The electromagnetic induction coil is equipped with a switch that connects the power supply when the water tank is released, and the switch remains normally open.

[0018] The above design features a detachable water tank with the inlet facing upwards, facilitating the insertion of a pumping pipe and making tank replacement convenient. A Hellbeck permanent magnet mechanism attracts a soft magnet above the water tank, allowing a drone to lift the tank into the air. The concentrated magnetic force of the Hellbeck permanent magnet mechanism strengthens the attraction, preventing the tank from falling. An electromagnetic induction coil is wound around the central permanent magnet and yoke. This coil releases the magnetic force of the Hellbeck permanent magnet mechanism, causing the tank to fall due to gravity. The drone then flies to another full water tank, activates a switch to release the electromagnetic induction coil, and the Hellbeck permanent magnet mechanism lifts the new tank. This allows for automated and rapid tank replacement without stopping the water filling process, saving time and effort.

[0019] Preferably, a receiving groove is provided above the water tank, and the soft magnet is disposed at the bottom of the receiving groove; the bottom of the fuselage is provided with a downwardly protruding outward structure, which matches the shape of the receiving groove; the permanent magnet mechanism is installed in the outward protruding structure. By providing a receiving groove, the outward protruding structure is embedded in the receiving groove, making it convenient for the drone to align with the water tank, thus facilitating quick replacement of the water tank. Furthermore, the Haierbeck permanent magnet mechanism is less prone to slippage after attracting the water tank, making the water tank less likely to fall off and ensuring safer operation.

[0020] Preferably, the receiving groove is square, and the convex structure is also a square convex structure that mates with the receiving groove; at least four soft magnets are provided, with at least one soft magnet at each of the four corners of the receiving groove; at least four Hellbeck permanent magnet mechanisms are provided, with at least one Hellbeck permanent magnet mechanism at each of the four corners of the convex structure; the positions of the Hellbeck permanent magnet mechanisms and the soft magnets correspond one-to-one. The provision of at least one soft magnet at each of the four corners of the receiving groove ensures magnetic attraction in all directions, improving the stable adsorption force on the water storage tank.

[0021] Preferably, the water tank has two water inlets, symmetrically arranged on both sides of the receiving tank. This facilitates docking of drones from both directions with the water tank, eliminating the need to identify the orientation and simplifying the docking process.

[0022] Preferably, it also includes a pushing mechanism, which includes an electrically operated telescopic rod located at the bottom of the machine body, with the telescopic end of the rod facing the water tank. This is to prevent the water tank from failing to detach due to gravity after the electromagnetic induction coil is energized; the electrically operated telescopic rod assists in the detachment of the water tank.

[0023] Preferably, the pushing mechanism uses a lead screw motor to drive the electric telescopic rod. The force of the lead screw motor ensures the thrust of the electric telescopic rod.

[0024] Preferably, at least three of the electrically operated telescopic rods are arranged along the perimeter of the water tank at positions corresponding to the machine body. The coordinated operation of the three electric telescopic rods propels the water tank more smoothly.

[0025] Preferably, the drone is equipped with an electric hose reel, and the water pumping pipe is wound around the electric hose reel. The electric hose reel controls the water pumping pipe to extend from the water inlet into the water storage tank. The water pumping pipe is extendable, facilitating connection between the water pumping pipe and the water inlet.

[0026] Preferably, the soft magnet is made of silicon steel. The high magnetic permeability of silicon steel soft magnets allows for higher magnetic flux density within the same volume, thus improving the attraction force of the Heilbeck permanent magnet mechanism on the soft magnet.

The phrase "in an embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single embodiment or an embodiment selectively excluded from other embodiments.

[0037] Example 1

[0038] Reference Figures 1-4 This embodiment provides a solar panel cleaning system suitable for drone suspension, including drone 1, which includes a fuselage.

[0039] The drone 1 is equipped with a spraying system, which includes a water tank 2, which is detachably installed at the bottom of the drone body.

[0040] The water storage tank 2 is provided with an upward-facing water inlet 21;

[0041] The spraying system includes a water pumping pipe 3, which is located at the bottom of the machine body and is inserted into the water inlet 21.

[0042] It also includes a magnetic attraction system;

[0043] The magnetic attraction system includes a soft magnet 45 disposed above the water storage tank 2;

[0044] The magnetic attraction system also includes a permanent magnet mechanism located at the bottom of the UAV 1;

[0045] The permanent magnet mechanism adopts a Heilbeck permanent magnet mechanism 4, which includes a middle permanent magnet 41, two end permanent magnets 42 and a yoke 43.

[0046] The yoke 43 is positioned above the intermediate permanent magnet 41 and the two end permanent magnets 42;

[0047] An electromagnetic induction coil 44 is wound around the intermediate permanent magnet 41 and the yoke 43. When the electromagnetic induction coil 44 is energized, it generates a magnetism that is opposite to that of the intermediate permanent magnet 41, and the magnetic force is not less than that of the intermediate permanent magnet 41.

[0048] The electromagnetic induction coil 44 is connected to the power supply of the UAV 1;

[0049] The electromagnetic induction coil 44 is equipped with a switch that connects the power supply when the water storage tank 2 is released, and the switch is kept normally open.

[0050] The water tank 2 is detachable, with the water inlet 21 facing upwards to allow the water pipe 3 to extend into the water tank 2 from above, facilitating water tank 2 replacement. A Hellbeck permanent magnet mechanism 4 attracts the soft magnet 45 above the water tank 2, allowing the drone 1 to lift the water tank 2 into the air. The concentrated magnetic force of the Hellbeck permanent magnet mechanism 4 strengthens the attraction, preventing the water tank 2 from falling off. An electromagnetic induction coil 44 is wound around the central permanent magnet 41 and the yoke 43, which reduces the magnetic force of the Hellbeck permanent magnet mechanism 4. If the water tank 2 falls due to gravity, the drone 1 flies to another water tank 2 filled with water. The switch is turned on to release the magnetic force of the electromagnetic induction coil 44, and the Hellbeck permanent magnet mechanism 4 lifts the water tank 2 back up. This allows for automated and rapid water tank 2 replacement without stopping water filling, saving time and effort.

[0051] A receiving groove 22 is provided above the water tank 2, and the soft magnet 45 is disposed at the bottom of the receiving groove 22; the bottom of the fuselage is provided with a downwardly protruding outward structure, which matches the shape of the receiving groove 22; the permanent magnet mechanism is installed in the outward structure. By providing the receiving groove 22, the outward structure is embedded in the receiving groove 22, making it convenient for the drone 1 to align with the water tank 2, thus facilitating quick replacement of the water tank 2. Furthermore, after the Haierbeck permanent magnet mechanism 4 attracts the water tank 2, it is less likely to slip, and the water tank 2 is less likely to fall off, making operation safer.

[0052] The receiving groove 22 is square, and the convex structure is also a square convex structure that cooperates with the receiving groove 22. At least four soft magnets 45 are provided, with at least one soft magnet 45 located at each of the four corners of the receiving groove 22. At least four Hellbeck permanent magnet mechanisms 4 are provided, with at least one Hellbeck permanent magnet mechanism 4 located at each of the four corners of the convex structure. The positions of the Hellbeck permanent magnet mechanisms 4 and the soft magnets 45 correspond one-to-one. The presence of at least one soft magnet 45 at each of the four corners of the receiving groove 22 ensures magnetic attraction in all directions, improving the stable adsorption force on the water storage tank 2.

[0053] The water tank is equipped with two water inlets 21, which are symmetrically arranged on both sides of the receiving tank 22. This facilitates docking of the drone 1 from two directions with the water tank 2, eliminating the need to identify the orientation and simplifying the docking process.

[0054] The soft magnet 45 is made of silicon steel. The high magnetic permeability of the silicon steel soft magnet 45 allows for a higher magnetic flux density within the same volume, thus improving the attraction force of the Heilbeck permanent magnet mechanism 4 on the soft magnet 45.

[0055] In use, when the water tank 2 is attached to the drone body, the switch is turned on, the electromagnetic induction coil 44 is de-energized, and the Heilbeck permanent magnet mechanism 4 maintains the attraction, thus adhering to the water tank 2. When the water tank 2 detaches, the switch is turned off, the electromagnetic induction coil 44 is energized, and the Heilbeck permanent magnet mechanism 4 reduces the attraction. The water tank 2 detaches from the weakened Heilbeck permanent magnet mechanism 4 due to its own weight. Before loading the water tank 2, the switch is turned on, the electromagnetic induction coil 44 is de-energized, and the Heilbeck permanent magnet mechanism 4 maintains the attraction, and the switch is kept open. The drone 1 is positioned at the new water tank 2, the receiving slot 22 aligns and engages with the outward protruding structure, and the four Heilbeck permanent magnet mechanisms 4 correspond one-to-one with the four soft magnets 45, completing the attachment of the drone 1 to the water tank 2.

[0056] Example 2

[0057] Reference Figure 1 and Figure 2 This is the second embodiment of the present invention, which is based on the previous embodiment.

[0058] It also includes a pushing mechanism, which comprises an electric telescopic rod located at the bottom of the machine body, with the telescopic end of the electric telescopic rod facing the water tank 2. This is to prevent the water tank 2 from failing to detach due to gravity after the electromagnetic induction coil 44 is energized; the electric telescopic rod assists in the detachment of the water tank 2.

[0059] The pushing mechanism uses a lead screw motor to drive the electric telescopic rod. The force of the lead screw motor ensures the thrust of the electric telescopic rod.

[0060] At least three electric telescopic rods are arranged along the perimeter of the water tank at positions corresponding to the machine body. The three electric telescopic rods work together to propel the water tank 2 more smoothly.

[0061] The drone 1 is equipped with an electric hose reel, and the water pumping pipe 3 is wound around the electric hose reel. The electric hose reel controls the water pumping pipe 3 to extend from the water inlet 21 into the water storage tank 2. The water pumping pipe 3 is extendable to facilitate connection between the water pumping pipe 3 and the water inlet 21.

[0062] During use, when the water tank 2 is attached to the drone body, the electric telescopic rod of the screw motor is retracted. When the water tank 2 detaches, the switch closes, the electromagnetic induction coil 44 is energized, and the Heilbeck permanent magnet mechanism 4 reduces the suction force. The screw motor drives the electric telescopic rod to extend and push the water tank 2 away, preventing the water tank 2 from failing to detach due to gravity after the electromagnetic induction coil 44 is energized. The electric telescopic rod assists in the detachment of the water tank 2. Before loading the water tank 2, the electric telescopic rod retracts, and the electric hose reel controls the water pumping pipe 3 to retract. The switch opens, the electromagnetic induction coil 44 is de-energized, and the Heilbeck permanent magnet mechanism 4 restores the suction force. The drone 1 positions itself at the new water tank 2, attaches to the water tank 2, and the electric hose reel controls the water pumping pipe 3 to extend and insert into the water tank 2.
