Description

Technical Field

[0001] The present invention relates to the technical field of photovoltaic inspection, and in particular to a photovoltaic inspection drone with auxiliary cleaning function and a use method thereof. Background Art

[0002] As the global energy crisis and environmental issues become increasingly prominent, solar energy as a clean and renewable energy source has received widespread attention. Solar photovoltaic power generation systems have been rapidly developed in many countries and regions due to their environmental protection and sustainability. However, during the long-term operation of photovoltaic panels outdoors, they are easily affected by pollutants such as dust, sand, and bird droppings, which leads to a decrease in light energy conversion efficiency and affects the overall performance of the photovoltaic power generation system. Therefore, it is very necessary to clean the photovoltaic panels regularly.

[0003] At present, there are two main ways to clean photovoltaic panels: manual cleaning and mechanical automatic cleaning. Although manual cleaning is low-cost, it is inefficient and has certain safety hazards; although mechanical automatic cleaning equipment can improve cleaning efficiency, the initial investment cost is high and the scope of application is limited. In recent years, with the development of drone technology, drone inspection has become an emerging means of photovoltaic panel inspection. By carrying various sensors, drones can quickly complete the hot spot detection and fault location of photovoltaic panels in the air, greatly improving the operation and maintenance efficiency of photovoltaic power stations.

[0004] However, most existing drone inspection solutions focus on detection and monitoring, and cannot take effective cleaning measures in a timely manner for the stains or obstacles found. In addition, although there are a few drone products with integrated cleaning devices on the market, the cleaning mechanisms of these products are often fixed and have poor flexibility. They are difficult to adapt to photovoltaic panels of different shapes and sizes, and the cleaning effect is poor; Most drone inspection systems in the prior art lack the ability to clean photovoltaic panels immediately, and the cleaning components of existing drones with cleaning functions are usually fixed in design and cannot be adjusted in position or angle according to actual conditions, which limits their application scenarios. At the same time, the cleaning operations in the prior art often fail to achieve the ideal cleaning effect, and sometimes even damage the photovoltaic panels due to improper operation. In view of the above problems, the present invention provides a photovoltaic inspection drone with auxiliary cleaning function and a method of using the same. Summary of the invention

[0031] A mounting bracket 200 is installed at the bottom of the drone body 100; a movable sleeve 201 is installed on the right side of the mounting bracket 200, and a supporting slide bar 202 is slidably sleeved on the outer surface of the movable sleeve 201, and the axial end of the supporting slide bar 202 is fixedly connected to the surface of the support frame 160. Therefore, the supporting slide bar 202 and the movable sleeve 201 cooperate to stably support the mounting bracket 200, and a pushing frame 210 is installed at one end of the mounting bracket 200 away from the movable sleeve 201, wherein a telescopic member 220 is installed at the end of the pushing frame 210, and the end of the telescopic member 220 is fastened to the bottom of the water tank 120 by bolts, and the output end of the telescopic member 220 is movably connected to the end of the pushing frame 210 through a rotating shaft, so that the telescopic member 220 can be used to push the pushing frame 210 downward with the supporting slide bar 202 as the center of the circle, thereby driving the cleaning assembly 600 and the nozzle 320 to clean, so as to subsequently perform auxiliary cleaning work on the photovoltaic panel.

[0032] A retractable assembly 400 is installed at one end of the mounting bracket 200; the retractable assembly 400 includes a driving motor 410, wherein one end of the driving motor 410 is connected to the surface of the pushing frame 210, the output end of the driving motor 410 is connected to a transmission shaft 411, and the axial end of the transmission shaft 411 is movably connected to the adjacent pushing frame 210, the front and rear ends of the surface of the driving motor 410 are both provided with a flip main board 420, and the surface of the driving motor 410 and one side of the flip main board 420 is provided with an auxiliary support plate 421, the auxiliary support plate 421 and the flip main board 420 are used together to provide auxiliary support to the rotating shaft rod 1 510 and the rotating shaft rod 2 520.

[0033] A winding seat 430 is arranged on the left side of the flip main board 420, wherein the front and rear ends of the left side of the winding seat 430 are connected with a flip auxiliary plate 440, and the flip auxiliary plate 440 is used for the installation of the cleaning assembly 600, wherein the opposite sides of the two flip main boards 420 are connected with a limiting support plate 310, and the surface of the water supply pipeline 300 passes through the limiting support plate 310 and is in sliding contact with the connection therewith, therefore, the limiting support plate 310 can be used to assist in supporting and limiting the limiting support plate 310.

[0034] Among them, a flip assembly 500 is installed on the surface of the retractable assembly 400, which is used to drive the flip auxiliary plate 440 to flip; the flip assembly 500 includes a rotating shaft rod 510 that passes through one end of the flip main board 420, and a rotating shaft rod 2 520 is arranged on the left side of the rotating shaft rod 1 510, wherein the rotating shaft rod 2 520 is used in conjunction with the winding seat 430, and the inner surface of the winding seat 430 is sleeved with the outer surface of the rotating shaft rod 2 520, and the surfaces of the rotating shaft rod 1 510 and the transmission shaft body 411 are both sleeved with a tooth transmission component 530, wherein the tooth transmission component 530 is located in the inner cavity of the flip main board 420, and the two tooth transmission components 530 are connected by chain meshing.

[0035] As a further optimization of this solution, the tooth transmission component 530 can also be a pulley, and the two pulleys are connected by a belt drive, so that when the transmission shaft 411 rotates, the rotating shaft 510 can be driven to rotate through the two matching tooth transmission components 530.

[0036] The shaft end of the rotating shaft rod 1 510 is sleeved with a toggle gear plate 1 540, and the shaft end of the rotating shaft rod 2 520 is sleeved with a toggle gear plate 2 541, wherein the toggle gear plate 1 540 and the toggle gear plate 2 541 are meshed with each other. Therefore, when the rotating shaft rod 1 510 is subjected to force to rotate, the rotating shaft rod 2 520 can be driven to rotate by the toggle gear plate 1 540 and the toggle gear plate 2 541. In order to provide auxiliary support for the rotating shaft rod 2 520 and increase the stability of the flip auxiliary plate 440, the shaft ends of the rotating shaft rod 2 520 and the rotating shaft rod 1 510 are movably sleeved with a stabilizing plate 550, and the stabilizing plate 550 is connected to the side opposite to the auxiliary support plate body 421.

[0037] Furthermore, under the action of the transmission shaft 411, the flip main board 420 can be driven to flip, extend or extend with the transmission shaft 411 as the center. Under the joint action of the two gear transmission components 530, the rotating shaft 1 510, the rotating shaft 2 520, the toggle gear plate 1 540 and the toggle gear plate 2 541, when the flip main board 420 is flipped, the flip auxiliary board 440 can be flipped in the opposite direction to the flip main board 420 with the rotating shaft 1 510 as the center, so that the flip auxiliary board 440 and the flip main board 420 are flipped and stacked together, so that during inspection, the stained photovoltaic panels can be reasonably cleared, avoiding the problem of the fixed setting of the flip main board 420 and the flip auxiliary board 440 occupying space.

[0038] A cleaning brush assembly 600 is installed at one end of the retracting assembly 400 away from the mounting bracket 200, and the cleaning brush assembly 600 is used to clean stubborn stains on the photovoltaic panel; the cleaning brush assembly 600 includes a cleaning brush roller 610, and the cleaning brush roller 610 is movably installed on a side of the flip auxiliary plate 440 away from the flip main board 420, and a transmission motor 620 is installed on the surface of the flip auxiliary plate 440, wherein the output end of the transmission motor 620 passes through the inner cavity of the flip auxiliary plate 440, and the axial end of the cleaning brush roller 610 passes through the outer side of the flip auxiliary plate 440 and is rotatably connected to the connection with the flip auxiliary plate 440 through a sealed bearing, and the surface of the transmission motor 620 and the axial end of the cleaning brush roller 610 are both provided with a transmission disc 621, and the two transmission discs 621 are connected by belt drive.

[0039] Furthermore, the cleaning roller 610 is a soft brush, such as a nylon brush, which can remove dust and dirt on the surface of the photovoltaic panel by rotating.

[0040] Furthermore, a protective cover is provided on the outer side of the transmission motor 620, and one end of the protective cover is fastened to the surface of the flip auxiliary plate 440 by bolts, thereby protecting the transmission motor 620 from rain.

[0041] Therefore, when the flip main board 420 and the flip auxiliary board 440 are flipped outward and unfolded, the cleaning roller 610 can be extended outward, and then the transmission motor 620 is driven to work to drive the cleaning roller 610 to rotate through the transmission disc 621, and the cleaning roller 610 is used to clean the surface of the photovoltaic panel. When the cleaning roller 610 is brushing the stains on the surface of the photovoltaic panel, the nozzle 320 sprays water at the same time, which can prevent the cleaning roller 610 from dry brushing the photovoltaic panel, which can not only increase the cleaning efficiency, but also clean the surface of the cleaning roller 610, and at the same time avoid the cleaning roller 610 from dry brushing the photovoltaic panel, causing damage to the photovoltaic panel.

[0043] The working principle of the photovoltaic inspection drone with auxiliary cleaning is as follows: under the stabilizing effect of the drone body 100 and the gimbal 140, the inspection camera module 130 is used to perform daily inspections on the photovoltaic panels; during the inspection, when there are stains on the surface of the photovoltaic panels, the telescopic member 220 is controlled to work, so that its output end drives the push-connection frame 210 to tilt downward with the support slide bar 202 as the center, and adjusts the posture of the nozzle 320 and the cleaning component 600; then the driving motor 410 is driven to work, so that the flip mainboard 420 is flipped and extended with the transmission shaft 411 as the center, and at the same time, the winding seat 43 0 and the influence of the toggle gear plate 1 540 and the toggle gear plate 2 541, the rotating shaft rod 1 510 drives the rotating shaft rod 2 520 to control the flip auxiliary plate 440 to flip outward until the cleaning roller 610 is extended outward; then the water pump 110 is controlled to deliver water to the limiting support plate 310, and the nozzle 320 is used to spray clean water to remove stains on the surface of the photovoltaic panel; when facing stubborn stains, the transmission motor 620 is controlled to work, drive the cleaning roller 610 to work, and cooperate with the nozzle 320 to spray clean water to wipe off the stains on the surface of the photovoltaic panel, so as to assist in decontamination of the surface of the photovoltaic panel.

Control the drone body 100 to work, and use the inspection camera module 130 to perform daily inspections on the photovoltaic panels under the stabilization of the gimbal 140; S2. During the inspection, when there are stains on the surface of the photovoltaic panel, the telescopic member 220 is controlled to work, so that the output end drives the push-joint frame 210 to tilt downward with the support slide bar 202 as the center, and the posture of the nozzle 320 and the cleaning assembly 600 is adjusted; S3. During the decontamination process, the driving motor 410 is driven to work, so that the flip main board 420 is flipped and extended with the transmission shaft 411 as the center. At the same time, under the influence of the winding seat 430 and the shifting gear plate 1 540 and the shifting gear plate 2 541, the rotating shaft 1 510 drives the rotating shaft 2 520 to control the flip auxiliary plate 440 to flip outward until the cleaning roller 610 is displayed outward; S4. After the brush roller 610 is displayed outward, the pump 110 is controlled to deliver water to the limit support plate 310, and the nozzle 320 is used to spray clean water to remove stains on the surface of the photovoltaic panel; S5.
