Description

Technical Field

[0001] The present invention relates to a cleaning device, specifically a cleaning device for photovoltaic panels based on an unmanned aerial vehicle (UAV). Background Art

[0002] With the increasingly deteriorating environment and the continuous reduction of non-renewable energy, photovoltaic power generation has gradually become one of the main clean energies. To ensure the power generation efficiency, photovoltaic power generation devices are usually installed in an unobstructed outdoor environment to ensure the light intensity. This makes the working environment of photovoltaic power generation devices relatively harsh, and various pollutants often accumulate on the surface of photovoltaic panels during use, seriously reducing the power generation efficiency of photovoltaic modules.

[0003] Currently, the method to solve this problem is to regularly clean the photovoltaic panels. The most common way is to use a UAV to clean the photovoltaic panels. However, existing UAVs usually need to carry their own water tanks to clean the photovoltaic panels. Due to the weight limit of the UAV itself, the capacity of the water tanks carried by the UAV is usually small, and during the cleaning process, it is necessary to frequently return to replenish the water in the water tank to continue cleaning the photovoltaic panels. This situation causes a large amount of time of the UAV to be wasted in returning to fetch water during operation, significantly reducing the cleaning efficiency of the UAV. Summary of the Invention

[0004] To solve the above-mentioned deficiencies in the prior art, the present invention aims to provide a cleaning device for photovoltaic panels based on a UAV, so as to achieve the purpose of enabling the UAV not to return to fetch water during the process of cleaning the photovoltaic panels, thereby improving the working efficiency when using the UAV to clean the photovoltaic panels.

One end of the power screw is fixedly connected to the power output end of the power motor, and the other end passes through the sliding frame and extends outside the mounting frame through a through hole opened on the mounting frame. The power screw is threadedly connected with the sliding frame, and the length of the power screw is greater than the length between the front and rear ends of the mounting frame.

[0008] As a further limitation of the present invention, a steering switch for changing the power output direction of the power motor is fixedly arranged on the side of the rotating frame facing the sliding frame and the front inner wall of the mounting frame.

[0009] As another limitation of the present invention, a water outlet hole is opened at the front end of the mounting frame, and a side plate for preventing the water sprayed by the cleaning unit from flowing away is also fixedly arranged inside the mounting frame; The water supply unit further includes a recovery tank and a filtering assembly.

[0012] As a further limitation of the present invention, sewage outlets are provided on the first cleaning box and the second cleaning box, and sewage doors are hinged at the sewage outlets.

[0013] As a third limitation of the present invention, the UAV body is a UAV capable of performing visual image processing, and the transport vehicle is an autonomous driving car.

[0014] Due to the adoption of the above technical solutions, the beneficial effects achieved by the present invention compared with the prior art are as follows: (1) The present invention designs a photovoltaic panel cleaning device that enables the UAV to continuously clean the photovoltaic panels. Specifically, a cleaning unit is suspended from the UAV, and the cleaning unit is fixed on the photovoltaic panel to clean the photovoltaic panel. At the same time, the present invention is also provided with a water supply unit for supplying water to the cleaning unit. The transport vehicle in the water supply unit will carry a water tank and move with the UAV to supply water to the cleaning unit at all times, so that the UAV does not need to return to fetch water, improving the cleaning efficiency of the photovoltaic panels.

[0015] (2) The cleaning unit of the present invention is provided with a fixing component. The rotating frame in the fixing component can slide on the mounting frame, and then drive the rear hook fixed on the rotating frame to move, so as to change the distance between the rear hook and the front hook. At the same time, the tension spring can provide a force to pull the rear hook towards the front hook, so that the front hook and the rear hook can clamp the photovoltaic panel to complete the fixation of the cleaning component on the photovoltaic panel. This fixing structure enables the cleaning unit to be fixed on photovoltaic panels of different sizes, enhancing the applicability of the present invention.

[0016] (3) The spray head in the present invention is fixed on the sliding frame. At the same time, the power motor can drive the power screw to rotate, so that the sliding frame threadedly connected to the power screw displaces along the power screw. And by changing the rotation direction of the power output end of the power motor, the displacement direction of the sliding frame can be changed, so that the spray head can clean every position of the photovoltaic panel, improving the cleaning effect.

[0017] (4) The mounting frame in the present invention is provided with a water outlet hole, and the water supply unit is provided with a recovery tank and a filtering component. The recovery tank is communicated with the water outlet hole through a water outlet pipe, so that the water sprayed by the cleaning unit will be recovered into the recovery tank after cleaning and filtered by the filtering component and then returned to the water tank for reuse. This method not only prevents the waste of water resources, but also improves the endurance of the present invention, enabling more photovoltaic panels to be cleaned without secondary water addition.

[0018] (5) In the mounting rack of the present invention, a side plate is fixedly installed. The side plate can collect the water sprayed by the cleaning unit, keeping it within the range of the mounting rack and the side plate all the time, and finally flowing into the water outlet hole, preventing water resource loss and waste.

At the same time, the filter mesh belt rotates driven by the first drive shaft and the second drive shaft. At this time, the first cleaning brush and the second cleaning brush will clean the filter mesh belt, so that the impurities on the filter mesh belt are swept into the first cleaning box and the second cleaning box, avoiding the situation that the filter mesh belt is blocked by impurities during operation, resulting in water blockage and filtration failure.

[0020] (7) In the present invention, sewage outlets are provided on both the first cleaning box and the second cleaning box, and sewage doors are hinged at the sewage outlets. After the work is completed, opening the sewage doors can discharge the impurities generated by filtration through the sewage outlets, facilitating the next use.

[0021] (8) The transport vehicle in the water supply unit of the present invention is an autonomous driving trolley.

Detailed implementation manners

[0025] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are only for the purpose of illustrating and understanding the present invention, and are not used to limit the present invention.

[0026] This embodiment discloses a cleaning device for photovoltaic panels based on a drone, including a drone body 1, a cleaning unit 2 and a water supply unit 3. In this embodiment, the drone body 1 is an existing drone capable of performing visual image processing. In actual use, by setting the path and training the actions, it can complete the work by itself.

[0027] As Figure 1 shown, the cleaning unit 2 includes a mounting frame 21, a fixing component 22 fixedly installed on the mounting frame 21, and a cleaning component 23. The fixing component 22 includes a hanging frame 221, a rotating frame 222, a tension spring 223, a front hook 224 and a rear hook 225. The rotating frame 222 is slidably installed on the mounting frame 21, and the rotating frame 222 is arranged parallel to the front and rear ends of the mounting frame 21. Both ends of the hanging frame 221 are rotatably connected to both ends of the rotating frame 222, so that the hanging frame 221 can rotate around the rotating frame 222 as an axis. The hanging frame 221 is hoisted on the drone body 1 through a towing rope. In this embodiment, two towing ropes are provided. The tension spring 223 is fixedly arranged between the rotating frame 222 and the front inner wall of the mounting frame 21. When the tension spring 223 is in a natural state, the rotating frame 222 is located in the latter half of the mounting frame 21, so that when the drone body 1 lifts the cleaning unit 2, the front end of the mounting frame 21 will be at a lower position. In this embodiment, two tension springs 223 are provided, and the two tension springs 223 are respectively located at positions close to both ends of the rotating frame 222. In this implementation, two front hooks 224 and two rear hooks 225 are provided. The two front hooks 224 are fixedly arranged on the front side of the mounting frame 21, and the two rear hooks 225 are fixedly arranged on the rotating frame 222.

[0028] During actual use, the UAV body 1 will identify the photovoltaic panel 4 through the vision system and fix the cleaning unit 2 on the photovoltaic panel 4 according to the pre-trained actions. Specifically, the UAV body 1 will first lift the cleaning unit 2 and fly above the target photovoltaic panel 4. At this time, the front end of the mounting frame 21 is at a lower position, so that the front hook 224 can hook on the lower end of the photovoltaic panel 4. Subsequently, the UAV body 1 moves towards the upper end of the photovoltaic panel 4. At this time, since the front hook 224 has been fixed, the UAV body 1 will pull the rotating frame 222 to move towards the upper end of the photovoltaic panel 4 during the process of moving towards the upper end of the photovoltaic panel 4. When the rotating frame 222 exceeds the upper end position of the photovoltaic panel 4, the UAV body 1 moves downward so that the mounting frame 21 is placed on the photovoltaic panel 4. Subsequently, the UAV body 1 moves towards the lower end of the photovoltaic panel 4, and the rotating frame 222 will also move towards the lower end of the photovoltaic panel 4 driven by the tension spring 223 until the rear hook 225 hooks on the upper end of the photovoltaic panel 4. As Figure 5 shown, at this time, the front hook 224 and the rear hook 225 will form a clamping fixation on the photovoltaic panel 4, so that the mounting frame 21 is fixed on the photovoltaic panel 4, and the cleaning unit 2 is also fixed on the photovoltaic panel 4.

[0029] As Figure 1 and Figure 2 shown, the cleaning assembly 23 includes a guide rod 231, a sliding frame 232, a spray head 233, a water inlet pipe 234, a power motor 235, a steering switch, and a power screw 236. Among them, a pair of guide rods 231 are provided, and the two guide rods 231 are respectively located at positions close to both ends of the rotating frame 222. The guide rods 231 are fixed between the front inner wall and the rear inner wall of the mounting frame 21, and the guide rods 231 are perpendicular to the front end and the rear end of the mounting frame 21. The sliding frame 232 is slidably mounted on the guide rod 231. The sliding frame 232 has a cavity structure inside, and the sliding frame 232 is connected to the water supply unit 3 through the water inlet pipe 234. In this embodiment, a plurality of spray heads 233 are provided, and the plurality of spray heads 233 are evenly fixed on the side of the sliding frame 232 facing the photovoltaic panel 4, and the spray heads 233 are connected to the inside of the sliding frame 232. The power motor 235 is fixed on the rotating frame 222. One end of the power screw 236 is fixedly connected to the power output end of the power motor 235, and the other end passes through the sliding frame 232 and extends outside the mounting frame 21 through a through hole opened on the mounting frame 21. The power screw 236 is threadedly connected to the sliding frame 232, and the length of the power screw 236 is greater than the length between the front and rear ends of the mounting frame 21. Two steering switches are provided, which are respectively fixed on the side of the rotating frame 222 facing the sliding frame 232 and the front inner wall of the mounting frame 21, and the steering switches are electrically connected to the power motor 235. When the steering switch is pressed, the power motor 235 will change the rotation direction of its power output end.

[0030] During actual use, the power motor 235 drives the power screw 236 to rotate. At this time, the sliding frame 232 threadedly connected to the power screw 236 slides on the guide rod 231 under the interaction of the threads. At the same time, the spray head 233 connected to the water supply assembly is driven by the sliding frame 232 to wash different positions of the photovoltaic panel 4.

[0031] It should be noted that the sliding frame 232 reciprocates between the rotating frame 222 and the mounting frame 21 to ensure that each position of the photovoltaic panel 4 is cleaned. Specifically, when the sliding frame 232 moves to the front end of the mounting frame 21, it contacts and presses the steering switch located on the inner wall of the front side of the mounting frame 21. At this time, the rotation direction of the power output end of the power motor 235 changes, causing the sliding frame 232 to continue moving to the other side; similarly, when the sliding frame 232 moves to one side of the rotating frame 222, it contacts the steering switch located on the rotating frame 222. At this time, the rotation direction of the power output end of the power motor 235 changes, causing the sliding frame 232 to continue moving to the other side.

[0032] As Figure 3 shown, the water supply unit 3 includes a transport vehicle 31, a water tank 32, a high-pressure water pump 33, a filtration assembly 35, and a recycling box 34. In this embodiment, the transport vehicle 31 is an existing self-driving vehicle. The water tank 32 is fixedly arranged on the transport vehicle 31, the high-pressure water pump 33 is fixedly arranged on the water tank 32, the water intake end of the high-pressure water pump 33 is located inside the water tank 32, and the water outlet end of the high-pressure water pump 33 is connected to the cleaning assembly 23 through a water inlet pipe 234. The filtration assembly 35 is fixedly arranged between the water tank 32 and the recycling box 34, and the recycling box 34, the filtration assembly 35, and the water tank 32 are all interconnected. During actual use, the path is input into the transport vehicle 31 in advance, and the transport vehicle 31 can travel along the path to work following the drone body 1. During the cleaning process, the high-pressure water pump 33 pumps the water in the water tank 32 into the cleaning unit 2 and sprays it through the spray head 233 to complete the cleaning of the photovoltaic panel 4.

[0033] It should be added that: a water outlet is provided at the front end of the mounting frame 21, and the water outlet is connected to the recovery box 34 through a water outlet pipe 237. A side plate 238 is also fixed inside the mounting frame 21. In this embodiment, two side plates 238 are provided, and the two side plates 238 are respectively located near the left and right ends of the mounting frame 21, and the ends of the two side plates 238 are fixed on the front inner wall of the mounting frame 21. When the mounting frame 21 is fixed on the photovoltaic panel 4, the two side panels 238 will contact the photovoltaic panel 4 and form a "U"-shaped structure together with the front side of the mounting frame 21. The cleaning water sprayed from the nozzle 233 will flow downward along the photovoltaic panel 4 after cleaning. When the cleaning water flows to the bottom of the photovoltaic panel 4, it will be blocked by the front end of the mounting frame 21. At this time, the side panels 238 at both ends of the "U"-shaped structure will limit the cleaning water within the range of the "U"-shaped structure, so that it will not flow out from both sides of the front end of the mounting frame 21, and the cleaning water can be collected into the recovery box 34 through the water outlet.

[0034] like Figure 4 As shown, the filter assembly 35 includes a shell 351, a filter mechanism, activated carbon 359, a first cleaning box 355, a second cleaning box 357, a first cleaning brush 356, a second cleaning brush 358 and a driving motor. Both ends of the shell 351 are hollow structures. A through hole penetrating the shell 351 is provided on the shell 351, and the height of the through hole is the same as the height of the filter mechanism. The first cleaning box 355 and the second cleaning box 357 are fixed at both ends of the shell 351, and the two ends of the through hole are respectively covered therein. The filter mechanism includes a first transmission shaft fixed in the first cleaning box 355, a second transmission shaft 353 fixed in the second cleaning box 357, and a filter belt 354 sleeved on the first transmission shaft 352 and the second transmission shaft 353, and the first transmission shaft 352 and the second transmission shaft 353 are flush with the two ends of the through hole. There are two drive motors, which are fixed in the first cleaning box 355 and the second cleaning box 357, respectively, and the power output ends of the two drive motors are fixedly connected to the first transmission shaft 352 and the second transmission shaft 353, respectively, for driving the first transmission shaft 352 and the second transmission shaft 353 to rotate. The filter belt 354 is penetrated in the shell 351 through a through hole. The first cleaning brush 356 is fixed on the inner bottom surface of the first cleaning box 355, and the second cleaning brush 358 is fixed on the inner top surface of the second cleaning box 357, and the top brush heads of the first cleaning brush 356 and the second cleaning brush 358 are in contact with the filter belt 354. It should be noted here that in this embodiment, the filter belt 354 that has not been cleaned will first pass through the first cleaning box 355 and then pass through the second cleaning box 357. Activated carbon 359 is placed in the shell 351, and the activated carbon 359 is located below the filter mechanism.

[0035] During actual use, the recycled water in the recycling box 34 will flow into the filtering component 35. After being filtered by the filter mesh belt 354 and the activated carbon 359, it will flow back into the water tank 32 to complete the recycling. During the filtering process, the filter mesh belt 354 is always kept rotating under the drive of the first transmission shaft and the second transmission shaft 353. When the part of the filter mesh belt 354 with impurities rotates into the first cleaning box 355, the first cleaning brush 356 located in the first cleaning box 355 will clean the filter mesh belt 354, causing the impurities on the filter mesh belt 354 to fall into the first cleaning box 355. Subsequently, this part of the filter mesh belt 354 will enter the second cleaning box 357, and the second cleaning brush 358 will perform secondary cleaning on this part of the filter mesh belt 354.

[0036] It should be supplemented here that: the first cleaning box 355 and the second cleaning box 357 are also provided with sewage outlets, and sewage doors are hinged at the sewage outlets. After the work is completed, opening the sewage doors can discharge the impurities in the first cleaning box 355 and the second cleaning box 357 from the sewage outlets.

[0037] When using this embodiment, first set the paths for the UAV body 1 and the transport vehicle 31, and input the pre-trained action instructions into the UAV body 1, then the cleaning work of the photovoltaic panel 4 can be started. During the work process, the UAV body 1 will automatically identify the target photovoltaic panel 4, fix the cleaning unit on the target photovoltaic panel 4, and then turn on the high-pressure water pump 33 to clean the photovoltaic panel 4. After the cleaning is completed, the UAV body 1 will automatically move to the next target photovoltaic panel 4 for cleaning according to the set path. At the same time, during the cleaning process, the used cleaning water will also be collected in the recycling box 34, filtered by the filtering component 35 and then refluxed to the water tank 32 for reuse.

[0038] It should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the above embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the above embodiments, or perform equivalent replacements on some of the technical features.
