Specific embodiments

[0022] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0023] Embodiment 1: Please refer to Figures 1 - 7 As shown, the present invention provides a technical solution: an inspection drone with a photovoltaic panel cleaning function, including a drone body 1, and an auxiliary mechanism 2 is arranged on the drone body 1; The auxiliary mechanism 2 includes a housing 201, a sealing plate 202 is installed on one side of the housing 201, an acceleration sensor 203 is installed on the surface of the housing 201, electric push rods 204 are installed at both the top and the bottom of the housing 201, a rectangular plate 205 is installed between the telescopic ends of the two electric push rods 204, four round rods 206 are fixed on the surface of the rectangular plate 205, an auxiliary rod 207 is fixed on the surface of the rectangular plate 205, a hanging ring 208 is arranged at one end of the auxiliary rod 207 away from the rectangular plate 205, five cylindrical holes 209 are opened in the inner wall of the housing 201, a rubber ring 210 is adhesively connected to the inner wall of each cylindrical hole 209, an installation shell 211 is installed inside the housing 201, an anti-slip ring 212 is adhesively connected to the inner wall of the installation shell 211, a colored smoke rod 213 is arranged inside the anti-slip ring 212, a telescopic tube 214 is installed on the surface of each electric push rod 204, one end of each telescopic tube 214 is installed on the surface of the rectangular plate 205, the telescopic ends of each electric push rod 204 are respectively located inside each telescopic tube 214, the four round rods 206 and the auxiliary rod 207 are respectively movably sleeved inside the five rubber rings 210, and the other side of the housing 201 is fixed to one side of the water tank 104.

[0024] In this embodiment, when the UAV body 1 needs to be used for work, first turn on the controller and set the acceleration threshold. Then, with the cooperation of the wireless remote controller, the UAV body 1 can work. During the work of the UAV body 1, the acceleration sensor 203 continuously detects the acceleration of the UAV body 1 in the vertical direction and transmits the detected acceleration data to the controller in the form of an electrical signal. At this time, the controller compares the received acceleration data with the pre-set acceleration threshold. When the received acceleration data is within the pre-set acceleration threshold range, the controller does not activate the two electric push rods 204. When the received acceleration data is greater than the pre-set acceleration threshold range, the controller activates the two electric push rods 204 simultaneously. At this time, the two activated electric push rods 204 drive the rectangular plate 205 to move horizontally with the cooperation of the housing 201. The horizontally moving rectangular plate 205 drives the four round rods 206 and the auxiliary rod 207 to move horizontally inside the corresponding rubber rings 210. At the same time, the horizontally moving rectangular plate 205 stretches the two telescopic tubes 214. Meanwhile, the horizontally moving auxiliary rod 207 drives the hanging ring 208 to move horizontally. The horizontally moving hanging ring 208 drives the pull ring on the colored smoke stick 213 to move horizontally with the cooperation of the mounting shell 211 and the anti-slip ring 212. When the rectangular plate 205 can no longer move, the pull ring on the colored smoke stick 213 is directly pulled off by the hanging ring 208, and the four round rods 206 all move out of the corresponding rubber rings 210. At the same time, the controller directly turns off the two electric push rods 204. The two turned-off electric push rods 204 stop the movement of the four round rods 206 and the hanging ring 208. Then, the colored smoke generated by the colored smoke stick 213 inside the anti-slip ring 212 is directly released inside the housing 201. Then, with the cooperation of the four corresponding rubber rings 210, the colored smoke inside the housing 201 is released into the environment. At this time, the staff can locate the UAV body 1 through the colored smoke released into the environment, so as to timely find the falling position of the UAV body 1.

[0025] Embodiment 2: According to Figures 1 - 4 and Figure 8As shown in the figure, the UAV body 1 includes a UAV main body 101. Four brackets 102 are installed on the UAV main body 101. An installation frame 103 is fixed between the four brackets 102. A water tank 104 is installed on the top of the installation frame 103. A water pump 105 is installed at the top groove of the water tank 104. Two fixing blocks 106 are fixed on the surface of the water tank 104. A servo motor 107 is installed on the surface of one of the fixing blocks 106. A rotating rod 108 is installed at the output end of the servo motor 107. A porous shell 109 is installed on the outer surface of the rotating rod 108. Hoses 110 are installed at both the water inlet end and the water outlet end of the water pump 105. A shunt pipe 111 is fixedly penetrated inside the porous shell 109. A spray head 112 is installed inside each through hole of the porous shell 109. One end of the rotating rod 108 movably penetrates the surfaces of the two fixing blocks 106. The water inlet end of one of the hoses 110 is installed with the water outlet end of the water tank 104. The water outlet end of the other hose 110 is installed with the water inlet end of the shunt pipe 111. Each water outlet end of the shunt pipe 111 is respectively installed with the water inlet end of each spray head 112.

[0026] In this embodiment, when it is necessary to inspect and clean the photovoltaic panel, first turn on the controller on the drone main body 101, and store the normal photo data of the photovoltaic panel in the storage module of the controller. Then, with the cooperation of the wireless transmitter on the drone main body 101, wirelessly connect the prepared wireless remote control to the controller (PLC controller). Next, set the flight route of the drone main body 101 and the parameters of the high-definition camera. When everything is ready, directly use the wireless remote control to start the drone main body 101 and make the drone main body 101 fly. At this time, the flying drone main body 101 will drive the components and the auxiliary mechanism 2 on it to fly together. When the drone main body 101 flies to a suitable position above the photovoltaic panel, at this time, with the cooperation of the wireless remote control, the controller, and the high-definition camera on the drone main body 101, take a photo of the photovoltaic panel. The high-definition camera will transmit the taken photo to the controller in the form of an electrical signal. At this time, the controller will compare the received photo data of the photovoltaic panel with the previously stored normal photo data of the photovoltaic panel. When the photo data of the photovoltaic panel received by the controller is the same as the previously stored normal photo data of the photovoltaic panel, at this time, the controller will not transmit the photo data of the photovoltaic panel to the wireless remote control. When the photo data of the photovoltaic panel received by the controller is different from the previously stored normal photo data of the photovoltaic panel, at this time, the controller will, with the cooperation of the wireless transmitter, transmit the photo data of the photovoltaic panel to the wireless remote control so that the staff can timely understand the situation of the photovoltaic panel. When the controller completes the photo-taking operation using the high-definition camera, at this time, the controller will, with the cooperation of the high-definition camera, directly start the servo motor 107. The started servo motor 107 will drive the rotating rod 108 to rotate with the cooperation of the two fixed blocks 106. The rotating rotating rod 108 will drive the flow dividing pipe 111 and the multiple nozzles 112 to rotate with the cooperation of the porous shell 109. When the multiple nozzles 112 all rotate to suitable angles, at this time, directly use the controller to turn off the servo motor 107. The turned-off servo motor 107 will, with the cooperation of the above components, make the multiple nozzles 112 all stop rotating. Then, directly use the controller to start the water pump 105. The started water pump 105 will pump out the water (previously injected) inside the water tank 104 and transport it to the inside of the flow dividing pipe 111 with the cooperation of the two hoses 110. Then, the water transported to the inside of the flow dividing pipe 111 will be respectively transported to the inside of the multiple nozzles 112 and sprayed out from the water outlet ends of the multiple nozzles 112. After that, use the remote control to start the drone main body 101 to make the drone main body 101 fly horizontally. At this time, the horizontally flying drone main body 101 will drive the multiple nozzles 112 to move horizontally with the cooperation of the four brackets 102, the mounting frame 103, the water tank 104, the two fixed blocks 106, the servo motor 107, the rotating rod 108, and the porous shell 109. At this time, it is possible to, with the cooperation of the multiple nozzles 112 that are moving horizontally and spraying water,Perform a cleaning operation on the dust on the surface of the photovoltaic panel. When the cleaning operation on the surface of the photovoltaic panel is completed, just operate according to the above operation steps.

[0027] The effects achieved by the entire mechanism and its working principle are as follows: When it is necessary to inspect and clean the photovoltaic panels, first turn on the controller on the drone body 101, store the normal photo data of the photovoltaic panels in the storage module of the controller, and set the acceleration threshold at the same time. Then, with the cooperation of the wireless transmitter on the drone body 101, wirelessly connect the prepared wireless remote control to the controller (PLC controller). Next, set the flight route of the drone body 101 and the parameters of the high-definition camera. When everything is ready, directly use the wireless remote control to start the drone body 101 and make the drone body 101 fly. At this time, the flying drone body 101 will drive the various components and the auxiliary mechanism 2 on it to fly together. When the drone body 101 flies to a suitable position above the photovoltaic panel, at this time, with the cooperation of the wireless remote control, the controller and the high-definition camera on the drone body 101, take a photo of the photovoltaic panel, and the high-definition camera will transmit the taken photo to the controller in the form of an electrical signal. At this time, the controller will compare the received photo data of the photovoltaic panel with the previously stored normal photo data of the photovoltaic panel. When the received photo data of the photovoltaic panel is the same as the previously stored normal photo data of the photovoltaic panel, the controller will not transmit the photo data of the photovoltaic panel to the wireless remote control. When the received photo data of the photovoltaic panel is different from the previously stored normal photo data of the photovoltaic panel, the controller will, with the cooperation of the wireless transmitter, transmit the photo data of the photovoltaic panel to the wireless remote control so that the staff can timely understand the situation of the photovoltaic panel. When the controller completes the photo-taking operation using the high-definition camera, at this time, with the cooperation of the high-definition camera, the controller will directly start the servo motor 107. At this time, the started servo motor 107 will drive the rotating rod 108 to rotate with the cooperation of the two fixed blocks 106, and the rotating rotating rod 108 will drive the shunt pipe 111 and the multiple nozzles 112 to rotate with the cooperation of the porous shell 109. When the multiple nozzles 112 all rotate to suitable angles, directly use the controller to turn off the servo motor 107. At this time, the turned-off servo motor 107 will, with the cooperation of the above-mentioned components, make the multiple nozzles 112 all stop rotating. Then, directly use the controller to start the water pump 105. At this time, the started water pump 105 will pump out the water (previously injected) inside the water tank 104 and transport it to the inside of the shunt pipe 111 with the cooperation of the two hoses 110. Then, the water transported to the inside of the shunt pipe 111 will be respectively transported to the inside of the multiple nozzles 112 and sprayed out from the water outlet ends of the multiple nozzles 112. After that, use the remote control to start the drone body 101 to make the drone body 101 fly horizontally. At this time, the horizontally flying drone body 101 will drive the multiple nozzles 112 to move horizontally with the cooperation of the four brackets 102, the mounting frame 103, the water tank 104, the two fixed blocks 106, the servo motor 107, the rotating rod 108 and the porous shell 109.At this time, the dust on the surface of the photovoltaic panel can be cleaned under the cooperation of multiple nozzles 112 that perform horizontal movement and spray water. When the cleaning operation of the surface of the photovoltaic panel is completed, just operate according to the above operation steps. During the use of the UAV body 1, the acceleration sensor 203 will continuously detect the acceleration of the UAV body 1 in the vertical direction, and transmit the detected acceleration data to the controller in the form of an electrical signal. At this time, the controller will compare the received acceleration data with the pre-set acceleration threshold. When the acceleration data received by the controller is within the pre-set acceleration threshold range, the controller will not activate the two electric push rods 204 at this time. When the acceleration data received by the controller is greater than the pre-set acceleration threshold range, the controller will activate the two electric push rods 204 at the same time. At this time, the two activated electric push rods 204 will drive the rectangular plate 205 to move horizontally under the cooperation of the housing 201. The horizontally moving rectangular plate 205 will drive the four round rods 206 and the auxiliary rod 207 to move horizontally inside the corresponding rubber rings 210. At the same time, the horizontally moving rectangular plate 205 will stretch the two telescopic tubes 214. At the same time, the horizontally moving auxiliary rod 207 will drive the hanging ring 208 to move horizontally. The horizontally moving hanging ring 208 will drive the pull ring on the colored smoke rod 213 to move horizontally under the cooperation of the mounting shell 211 and the anti-slip ring 212. When the rectangular plate 205 can no longer move, the pull ring on the colored smoke rod 213 will be directly pulled off by the hanging ring 208, and the four round rods 206 will all move out of the corresponding rubber rings 210. At the same time, the controller will directly turn off the two electric push rods 204. At this time, the two turned-off electric push rods 204 will stop the four round rods 206 and the hanging ring 208 from moving. Subsequently, the colored smoke generated by the colored smoke rod 213 inside the anti-slip ring 212 will be directly released inside the housing 201. Then, with the cooperation of the four corresponding rubber rings 210, the colored smoke inside the housing 201 will be released into the environment. At this time, the staff can locate the UAV body 1 through the colored smoke released into the environment, so as to timely discover the falling position of the UAV body 1.,

[0028] Among them, the hanging ring 208 is similar to the hanging ring on a safety rope, and the hanging ring 208 is connected to the pull ring of the colored smoke rod 213.

[0029] Among them, the controller is electrically connected to the battery, and the drive motor, high-definition camera, wireless transmitter, electronic speed controller, global positioning system module and inertial measurement unit are all electrically connected to the controller. The water pump 105, servo motor 107, acceleration sensor 203 and the two electric push rods 204 are all electrically connected to the controller.

[0030] Among them, the UAV main body 101 mainly includes the following components: Housing: Provides an installation base and support for other components; Battery: Provides power support for various components on the UAV body 101; Drive motor and propeller: Provide flight power for the UAV body 101, enabling it to take off, hover, fly, and land; Controller: Coordinates and controls various components of the UAV; Wireless transmitter: Enables data transmission and instruction interaction between the UAV body 101 and the ground remote controller; High-definition camera: Shoots high-definition images of the photovoltaic panels, used to detect the appearance condition of the photovoltaic panels and provide visual information for the staff; Electronic speed controller: Precisely controls the speed of the drive motor, and thus adjusts the thrust of the propeller; Global positioning system module: Provides accurate position information for the UAV body 101, and realizes functions such as navigation and route planning; Inertial measurement unit: Provides real-time attitude information of the UAV for the controller.

[0031] The working principle of the UAV body 101 is as follows: The staff sets flight tasks and parameters, such as inspection routes and photo-taking points, etc., through the remote controller. After the UAV body 101 takes off, the controller, based on the position information provided by the global positioning system module and the attitude information provided by the inertial measurement unit, precisely controls the speed of the drive motor through the electronic speed controller, so that the propeller generates appropriate thrust to keep the UAV body 101 flying according to the preset route and attitude. During the flight, the high-definition camera takes images of the photovoltaic panels at set time intervals or at specific positions, and these images are sent to the remote controller through the wireless transmitter. When the UAV body 101 completes the inspection task, the staff sends a landing instruction through the remote controller, and the UAV body 101 lands safely under the control of the controller.
