Description

Technical Field

[0001] This utility model relates to the field of photovoltaic cleaning technology, specifically to an adsorption-type photovoltaic cleaning flying robot. Background Technology

[0002] Currently, most photovoltaic (PV) power generation systems utilize multiple PV panels to generate more electricity. However, after prolonged use, a large amount of dust accumulates on the surface of these panels, significantly impacting their power generation efficiency. Therefore, regular cleaning is necessary. To reduce the labor intensity of cleaning operations, various types of flying PV cleaning robots have emerged. However, existing flying PV cleaning robots still have the following drawbacks in actual operation: 1. The robots mostly rely on tracked walking components for movement. For PV panels with large tilt angles, this can easily lead to sideslip, greatly limiting the robot's application scenarios; 2. Traditional flying cleaning robots mostly use rotary-wing drones as their flight components. During takeoff, the drone quickly levels itself, making it highly susceptible to collisions between the drone's propellers and the PV panels, causing accidents. Therefore, this case study addresses these issues and has been developed. Utility Model Content

[0003] To address the shortcomings of existing technologies, this invention provides an adsorption-type photovoltaic cleaning flying robot, which solves the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model is implemented through the following technical solution: an adsorption-type photovoltaic cleaning flying robot, comprising a tracked robot and a rotary-wing drone mounted on the upper part of the tracked robot. The tracked robot is provided with electric cleaning rollers on its front and rear sides respectively. A semi-circular shell is fastened to the outside of the electric cleaning rollers. A negative pressure dust suction mechanism is provided on the shell. Two sets of negative pressure adsorption mechanisms are symmetrically arranged inside the tracked robot along its central axis. Telescopic leveling components are symmetrically arranged on both sides of the negative pressure adsorption mechanisms. The negative pressure adsorption mechanism includes an exhaust chamber and an adsorption chamber. The exhaust chamber is an L-shaped pipe, and a negative pressure fan is installed inside the exhaust chamber. The adsorption chamber is located at the lower end of the exhaust chamber. The connection between the adsorption chamber and the L-shaped pipe is a rigid material cavity structure, and a soft silicone gasket is provided at the lower part of the rigid material cavity structure.

[0005] The aforementioned negative pressure dust collection mechanism includes a dust collection hood mounted on the housing, a dust discharge channel inside the dust collection hood, a dust filter screen at the outlet end of the dust discharge channel, a dust collection fan outside the dust filter screen, and a dust collection component at the bottom of the dust discharge channel.

[0006] The aforementioned dust collection component includes a dust collection chamber located below the dust discharge pipe, and a dust collection box is inserted into the dust collection chamber. The dust collection box has a rectangular trough structure and is located below the dust filter screen.

[0007] The aforementioned telescopic leveling assembly includes four sets of electric telescopic rods and rubber pads. The four sets of electric telescopic rods are arranged in a rectangular array on the tracked robot and their telescopic ends can extend below the chassis. The rubber pads are placed on the telescopic ends of the electric telescopic rods. Beneficial effects

[0008] This utility model provides an adsorption-type photovoltaic cleaning flying robot. It has the following advantages: Based on an existing tracked robot, this adsorption-type photovoltaic cleaning flying robot combines a rotary-wing UAV with the tracked robot to achieve flight control of the tracked UAV. Two sets of electric cleaning rollers and a negative pressure suction mechanism are installed on the front and rear sides of the tracked robot. Dust stirred up by the rollers is collected by the negative pressure suction mechanism, preventing secondary contamination of the photovoltaic panels. Simultaneously, two sets of negative pressure adsorption mechanisms are added to the tracked robot, using negative pressure to adhere the robot to the photovoltaic panel surface, counteracting downward lateral slippage and preventing sideslip. When the cleaning robot passes through gaps in the photovoltaic panels, whether moving forward or backward, if one set of negative pressure adsorption mechanisms fails to adsorb due to the gap, the other set will continue to operate normally, ensuring the cleaning robot continues its work smoothly. Furthermore, a telescopic leveling component is added to provide auxiliary support during takeoff and landing, ensuring the rotary-wing UAV takes off and lands parallel to the photovoltaic panels and preventing collisions between the UAV's propellers and the photovoltaic panels.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Example: Refer to the appendix of the instruction manual Figure 1-7As can be seen, this application specifically designs an adsorption-type photovoltaic cleaning flying robot, including a tracked robot 1 and a rotorcraft drone 2 mounted on the tracked robot 1. Electric cleaning rollers 3 are respectively arranged on the front and rear sides of the tracked robot 1. A semi-circular shell 4 is fastened to the outside of the electric cleaning rollers 3, and a negative pressure suction mechanism is arranged on the shell. Two sets of negative pressure adsorption mechanisms are symmetrically arranged along the central axis inside the tracked robot 1, and telescopic leveling components are symmetrically arranged on both sides of the negative pressure adsorption mechanisms. Based on the existing tracked robot 1, the rotorcraft drone 2 is combined with the tracked robot 1 to achieve flight control of the tracked drone. Two sets of electric cleaning rollers 3 and negative pressure suction mechanisms are arranged on the front and rear sides of the tracked robot 1. The dust brushed up by the rollers is collected by the negative pressure suction mechanism to avoid secondary contamination of the photovoltaic panels. At the same time, two sets of negative pressure adsorption mechanisms are added to the tracked robot 1 to adsorb the robot onto the surface of the photovoltaic panel through negative pressure, counteracting the downward force. Side slip force is used to prevent side slippage. When the cleaning robot passes through the gaps in the photovoltaic panels, whether moving forward or backward, if one set of negative pressure adsorption mechanisms cannot produce adsorption due to the gaps, the other set of negative pressure adsorption mechanisms will work normally, and the cleaning robot will still operate normally, further ensuring the smooth progress of the cleaning operation. In addition, a telescopic leveling component is added to provide auxiliary support during takeoff and landing, thereby ensuring that the rotor drone 2 takes off and lands in parallel and avoids the upper blades of the drone colliding with the photovoltaic panels. The negative pressure adsorption mechanism includes an exhaust chamber 5 and an adsorption chamber 6. The exhaust chamber 5 is an L-shaped pipe, and a negative pressure fan 7 is installed inside the exhaust chamber 5. The adsorption chamber 6 is located at the lower end of the exhaust chamber 5. The connection between the adsorption chamber 6 and the L-shaped pipe is a rigid material cavity structure, which will not deform due to negative pressure. A soft silicone gasket is provided at the bottom of the rigid material cavity structure. The material is soft and can perfectly fit with the photovoltaic panel to form a sealed negative pressure space without scratching the surface of the photovoltaic panel.

[0019] In the specific implementation process, the above-mentioned negative pressure dust collection mechanism includes a dust collection hood 8 installed on the housing, a dust discharge channel 9 opened inside the dust collection hood 8, a dust filter 10 installed at the outlet end of the dust discharge channel 9, a dust collection fan 11 installed outside the dust filter 10, and a dust collection component installed at the bottom of the dust discharge channel 9. The dust collection component includes a dust collection chamber 12 opened below the dust discharge channel, and a dust collection box 13 inserted in the dust collection chamber 12. The dust collection box 13 has a rectangular groove structure and is located below the dust filter 10. Under the suction of the dust collection fan 11, the dust washed off is sucked into the dust collection hood 8 through the dust discharge channel 9. After the dust is intercepted by the dust filter 10, it falls into the dust collection box 13 below. After the operation is completed, the dust collection box 13 can be removed and cleaned.

[0020] In the specific implementation process, the above-mentioned telescopic leveling component includes four sets of electric telescopic rods 14 and rubber pads. The four sets of electric telescopic rods 14 are arranged in a rectangular array on the tracked robot 1, and the telescopic ends can extend below the chassis. The rubber pads are set on the telescopic ends of the electric telescopic rods 14. Four electric telescopic rods 14 are set at the lower part of the tracked robot 1, and the extension and retraction are controlled by an internal motor. When the overall cleaning robot flies to land above the photovoltaic panel at a large angle, when one side of the track contacts the photovoltaic panel while the other side does not, the electric telescopic rod 14 on the side that is not in contact starts to work and extends synchronously so that the lower rubber pad contacts the photovoltaic panel, keeping the cleaning robot in a horizontal state. After the rotor drone 2 stops working, the electric telescopic rods 14 retract, so that the robot sticks to the surface of the photovoltaic panel. At the same time, the negative pressure adsorption mechanism works synchronously to generate suction to adsorb the photovoltaic panel so that it does not slip.

[0021] It should be further noted that the adsorption-type photovoltaic cleaning flying robot can automatically calculate the suction force of the negative pressure adsorption mechanism corresponding to the downward force generated by the cleaning robot under different photovoltaic panel angles through the control system, and adjust it by the power of the wind pressure fan. This way, the suction force is neither too strong, which would make it difficult for the robot to walk, nor too weak, which would cause side slippage, thus making reasonable use of power resources. The tracked robot 1 can model and automatically plan its walking route on the photovoltaic panel, and can carry out normal cleaning operations without manual intervention.

[0022] After the cleaning robot finishes its work, the two electric telescopic rods 14 on one side extend directly, and the negative pressure suction mechanism stops working, allowing the robot to reach a horizontal position. The flight function is then activated, and the electric telescopic rods 14 retract, allowing the robot to proceed to the next work location or return to its previous position. It is particularly important to note that the robot should take off and land at the highest point of the photovoltaic panel. Because the rotorcraft 2 will level itself upon takeoff, and the propellers are in a parallel position, the photovoltaic panel is arranged at a certain angle. If the angle is large, the upper propellers of the drone are highly likely to collide with the photovoltaic panel, potentially causing an accident. Choosing the highest point for takeoff and landing can minimize the risk of such accidents.

[0023] It should be noted that, in this document, relational terms such as "first" and "second" are used merely to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitations, the phrase "comprising an element defined as..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.

[0024] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
