[0043] like Figure 1 , Figure 5 , Figure 6 and Figure 7As shown, the camera cleaning device 12 of the embodiment of the utility model includes: a liquid spraying component 121, a driving component 125 and a pneumatic component 126.

[0044] The camera cleaning device 12 is mainly used in the drone 1 , which includes a drone body 11 and a camera 13 disposed on the drone body 11 . Exemplarily, the camera 13 is disposed at the bottom of the drone body 11 .

[0045] The liquid spraying assembly 121 includes a liquid spraying pipe 1211 and a liquid storage tank 1212. The liquid spraying pipe 1211 is connected to the liquid storage tank 1212 and is suitable for spraying cleaning liquid to the camera 13. The air pressure assembly 126 includes a cylinder 1263, a piston 1266 and a piston rod 1262. The piston rod 1262 is penetrated through the cylinder 1263 and connected to the piston 1266. The driving assembly 125 is connected to the piston rod 1262. Under the drive of the driving assembly 125, the piston rod 1262 can drive the piston 1266 to reciprocate in the cylinder 1263. Among them, the cylinder 1263 is connected with an air inlet pipeline 1265 and an air outlet pipeline 1264, and the air outlet pipeline 1264 is connected to the liquid storage tank 1212.

[0046] It should be noted that the main purpose of the camera cleaning device 12 is to clean the camera 13 regularly or irregularly to remove impurities such as dust and oil that may be attached to the surface of the camera 13, so as to ensure that the camera 13 can capture clear and accurate images.

[0047] Specifically, the liquid spraying assembly 121 is composed of a liquid spraying pipe 1211 and a liquid storage tank 1212. The liquid spraying pipe 1211 is connected to the liquid storage tank 1212. When the camera 13 needs to be cleaned, the cleaning liquid is sprayed onto the surface of the camera 13 through the liquid spraying pipe 1211. The liquid storage tank 1212 is responsible for storing the cleaning liquid to ensure that the liquid spraying pipe 1211 has sufficient cleaning liquid supply.

[0048] In addition, the piston rod 1262 is inserted into the cylinder 1263 and connected to the piston 1266. The cylinder 1263 is connected with an air inlet line 1265 and an air outlet line 1264. The air inlet line 1265 is used to introduce external air, and the air outlet line 1264 is connected to the liquid storage tank 1212. The driving assembly 125 is connected to the piston rod 1262. Through the driving of the driving assembly 125, the piston rod 1262 can drive the piston 1266 to reciprocate in the cylinder 1263. At this time, the outside air is sucked in and compressed, and then pressed into the liquid storage tank 1212, thereby pushing the cleaning liquid to be sprayed out through the spray pipe 1211.

[0049] It should be noted that the air inlet pipeline 1265 is provided with an air inlet check valve, and the air outlet pipeline 1264 is provided with an air outlet check valve. In addition, the water outlet of the liquid spraying pipe 1211 is provided with a spray head.

[0050] In the embodiment of the utility model, when the camera 13 needs to be cleaned, the driving assembly 125 is started, and the piston 1266 reciprocates in the cylinder 1263. Air enters the cylinder 1263 through the air inlet line 1265, is compressed by the piston 1266, and enters the liquid storage tank 1212 through the air outlet line 1264. As the air pressure in the liquid storage tank 1212 changes, the cleaning liquid is pushed and sprayed onto the surface of the camera 13 through the liquid spray pipe 1211, so as to complete the automatic cleaning of the camera 13.

[0051] In an optional embodiment, if Figure 5 , Figure 6 and Figure 7 As shown, the driving assembly 125 includes a driving motor 1251 and a cam 1252 , the cam 1252 is arranged on the output shaft of the driving motor 1251 , and the pneumatic assembly 126 also includes a connecting plate 1261 , the connecting plate 1261 is connected to the free end of the piston rod 1262 , and the cam 1252 is connected to the connecting plate 1261 .

[0052] It should be noted that the drive motor 1251 serves as a power source to provide the required driving force, and the cam 1252 is arranged on the output shaft of the drive motor 1251 and rotates as the motor rotates. Through the profile of the cam 1252, the reciprocating motion of the piston rod 1262 can be realized, and the speed and stroke of its movement can be controlled. Among them, the connecting plate 1261 is connected to the free end of the piston rod 1262, and through the connecting plate 1261, the piston rod 1262 can be effectively connected to the cam 1252 of the drive assembly 125. When the drive motor 1251 rotates, the cam 1252 pushes the piston rod 1262 to reciprocate through the connecting plate 1261, thereby driving the piston 1266 to perform the same movement in the cylinder 1263.

[0053] It should be pointed out here that in order to increase the air intake volume, the air pressure assembly 126 may include at least two cylinders 1263, and each cylinder 1263 is correspondingly provided with a piston 1266 and a piston rod 1262.

[0054] In order to ensure the stability and accuracy of the piston rod 1262 during the reciprocating motion, in an optional embodiment, as Figure 5 , Figure 6 and Figure 7 As shown, the camera cleaning device 12 also includes a guide assembly 124, which includes a guide rod 1241 and an elastic member 1242. The guide rod 1241 is arranged on the liquid storage tank 1212 and passes through the connecting plate 1261. The elastic member 1242 is wrapped around the guide rod 1241 and is located between the liquid storage tank 1212 and the connecting plate 1261.

[0055] The connecting plate 1261 is used as the connection point between the piston rod 1262 and the driving assembly 125, and can stably move in the vertical direction under the guidance of the guide rod 1241. The elastic member 1242 is wound around the guide rod 1241 and is located between the liquid storage tank 1212 and the connecting plate 1261. The function of the elastic member 1242 is to provide necessary buffering and support during the reciprocating motion of the piston rod 1262, so as to prevent component damage or motion error caused by excessive impact force or unstable motion.

[0056] In specific applications, the guide rod 1241 can be designed as a smooth cylindrical shape to ensure that the connecting plate 1261 can slide smoothly thereon. The elastic member 1242 can be made of a material with suitable rigidity and elasticity, such as a spring or rubber, to adapt to different working environments and movement requirements.

[0057] In an optional embodiment, if Figure 6 As shown, a mounting groove is provided on one side of the connecting plate 1261 facing the cam 1252 , a roller 12611 is rotatably provided in the mounting groove, and the cam 1252 is connected to the roller 12611 .

[0058] It should be noted that the function of the mounting groove is to provide a mounting space for accommodating the roller 12611 and ensuring that it can rotate stably. For example, the roller 12611 is arranged in the mounting groove through the roller 12611 axis. The roller 12611 is rotatably arranged in the mounting groove, and its outer surface matches the profile of the cam 1252. When the driving motor 1251 drives the cam 1252 to rotate, the profile of the cam 1252 contacts the outer surface of the roller 12611, thereby driving the roller 12611 to rotate.

[0059] Since the roller 12611 can rotate freely in the mounting groove, when the cam 1252 rotates, the roller 12611 can smoothly follow the profile of the cam 1252 to roll, rather than being directly subjected to the friction resistance of the cam 1252. The rolling contact method greatly reduces friction loss, improves movement efficiency, and also reduces wear of components and prolongs service life.

[0060] In an optional embodiment, if Figure 5 As shown, the liquid spraying assembly 121 further includes a liquid replenishing pipeline 1213 , which is connected to the liquid storage tank 1212 , and a control valve is provided on the liquid replenishing pipeline 1213 .

[0061] The main function of the replenishment pipeline 1213 is to provide cleaning liquid replenishment to the liquid storage tank 1212, ensuring that the cleaning liquid in the liquid storage tank 1212 can maintain a sufficient supply during a long cleaning operation. The introduction of the replenishment pipeline 1213 solves the problem of cleaning interruption caused by insufficient cleaning liquid in the traditional design and improves the continuous operation capability.

[0062] The control valve provided on the liquid replenishment pipeline 1213 is mainly used to control the on-off of the liquid replenishment pipeline 1213, so as to realize the precise control of the liquid replenishment process. By adjusting the opening of the control valve, we can open or close the liquid replenishment pipeline 1213 in a timely manner according to the remaining amount of cleaning liquid in the liquid storage tank 1212, so as to ensure that the cleaning liquid in the liquid storage tank 1212 is always kept at an appropriate level. For example, we can set a minimum liquid level threshold of the cleaning liquid. When the cleaning liquid in the liquid storage tank 1212 is lower than this threshold, the control valve on the liquid replenishment pipeline 1213 is opened to replenish the cleaning liquid in the liquid storage tank 1212.

[0063] In an optional embodiment, if Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the camera cleaning device 12 also includes a wiping component 122 and a transmission component 123. The wiping component 122 includes an arc-shaped wiping block 1223, a rotating ring 1222 and an arc-shaped mounting plate 1221. The rotating ring 1222 is rotatably arranged at the bottom of the UAV body 11 and is located at the periphery of the camera 13. The arc-shaped mounting plate 1221 is arranged on the side of the rotating ring 1222 away from the UAV body 11. The arc-shaped wiping block 1223 is arranged on the side of the arc-shaped mounting plate 1221 facing the camera 13, and the arc-shaped wiping block 1223 can abut against the outer surface of the camera 13.

[0064] The driving assembly 125 is connected to the rotating ring 1222 via the transmission assembly 123 . Driven by the driving assembly 125 , the rotating ring 1222 can drive the arc-shaped wiper block 1223 to rotate relative to the camera 13 .

[0065] It should be noted that when the rotating ring 1222 rotates, it can perform a circular motion around the camera 13. The arc-shaped mounting plate 1221 is fixed on the rotating ring 1222 to support and fix the arc-shaped cleaning block 1223. The arc-shaped cleaning block 1223 is mounted on the arc-shaped mounting plate 1221, and its shape matches the surface of the camera 13 to ensure that it can fit tightly and wipe effectively. The material of the arc-shaped cleaning block 1223 is a soft material with a certain friction force, so that stains and dust on the surface of the camera 13 can be easily removed.

[0066] In addition, the function of the transmission assembly 123 is to connect the driving assembly 125 and the rotating ring 1222. It can transmit the power of the driving assembly 125 to the rotating ring 1222, thereby driving the rotation of the rotating ring 1222. Under the drive of the driving assembly 125, the transmission assembly 123 transmits the power to the rotating ring 1222. The rotating ring 1222 rotates accordingly, driving the arc-shaped mounting plate 1221 and the arc-shaped cleaning block 1223 to move together. Since the arc-shaped cleaning block 1223 is closely fitted with the outer surface of the camera 13, when the arc-shaped cleaning block 1223 rotates with the rotating ring 1222, it can wipe the surface of the camera 13 and effectively remove stains and dust.

[0067] In a specific application, the liquid spraying component 121 can be used to spray cleaning liquid on the camera 13, and at the same time, the wiping component 122 can be used to wipe it. In this way, it can be ensured that the stains and dust on the surface of the camera 13 are completely removed, and its original clarity and glossiness are restored.

[0068] In an optional embodiment, if Figure 3 and Figure 4 As shown, the wiping assembly 122 also includes a plurality of guide blocks 1224, which are sequentially arranged on the rotating ring 1222 along the circumferential direction of the rotating ring 1222, and the drone body 11 is provided with a guide groove 111 adapted to the plurality of guide blocks 1224, and the plurality of guide blocks 1224 are slidably arranged in the guide groove 111.

[0069] It should be noted that a plurality of guide blocks 1224 are sequentially arranged on the rotating ring 1222 along the circumferential direction of the rotating ring 1222. These guide blocks 1224 play a role of positioning and guiding, ensuring that the rotating ring 1222 can maintain a stable and precise motion trajectory during the rotation process. The shape and size of the guide blocks 1224 match the guide grooves 111 to ensure that they can slide smoothly in the guide grooves 111. In addition, the guide grooves 111 on the drone body 11 provide stable support and guidance for the rotating ring 1222. The guide blocks 1224 can be fully embedded in the guide grooves 111 and will not fall off or shake during the rotation process.

[0070] In an optional embodiment, if Figure 4 As shown, the transmission assembly 123 includes a transmission gear 1236, a ring gear 1238, a first bevel gear 1233 and a second bevel gear 1234, the driving assembly 125 is connected to the first bevel gear 1233, the first bevel gear 1233 is meshingly connected to the second bevel gear 1234, the transmission gear 1236 is coaxially connected to the second bevel gear 1234 through a first connecting shaft, and the ring gear 1238 is sleeved on the outer periphery of the rotating ring 1222 and meshingly connected to the transmission gear 1236.

[0071] It should be noted that the driving assembly 125 is connected to the first bevel gear 1233. The power generated by the driving assembly 125 can be directly transmitted to the first bevel gear 1233, thereby driving it to rotate. When the first bevel gear 1233 rotates, it drives the second bevel gear 1234 to rotate through meshing. When the second bevel gear 1234 rotates, the transmission gear 1236 also rotates. When the transmission gear 1236 rotates, it drives the ring gear 1238 to rotate through meshing, thereby driving the rotating ring 1222 to rotate.

[0072] In an optional embodiment, if Figure 4 As shown, the transmission assembly 123 also includes a first sprocket 1231, a second sprocket 1237 and a transmission chain 1232, the first sprocket 1231 is connected to the second sprocket 1237 through the transmission chain 1232, the first sprocket 1231 is connected to the driving assembly 125, and the second sprocket 1237 is coaxially connected to the first bevel gear 1233 through a second connecting shaft.

[0073] Specifically, the first sprocket 1231 is connected to the second sprocket 1237 through the transmission chain 1232, and the first sprocket 1231 is connected to the driving assembly 125, and the power generated by the driving assembly 125 can be directly transmitted to the first sprocket 1231, and then transmitted to the second sprocket 1237 through the transmission chain 1232. The second sprocket 1237 will drive the first bevel gear 1233 to rotate, thereby realizing the power transmission of the entire transmission assembly 123.

[0074] In an optional embodiment, if Figure 4 As shown, the transmission assembly 123 further includes a fixing plate 1235 , which is suitable for being connected to the drone body 11 , and the first bevel gear 1233 is rotatably disposed on the fixing plate 1235 .

[0075] During the installation process, the fixing plate 1235 is connected to the drone body 11. The connection method can be bolt connection, welding or other reliable connection methods to ensure that the connection between the fixing plate 1235 and the drone body 11 is firm and reliable. Through the connection of the fixing plate 1235, the transmission assembly 123 can be stably installed on the drone 1, thereby ensuring its stability and reliability during operation. Exemplarily, the second connecting shaft is inserted into the first bevel gear 1233 and rotatably arranged on the fixing plate 1235.

[0076] The working process of the camera cleaning device 12 according to the embodiment of the utility model is described in detail below.

[0077] During operation, when the drone 1 has been used for a long time, dust will adhere to the lens surface of the camera 13, and the dust will make the image taken by the camera 13 unclear. The lens surface of the camera 13 needs to be cleaned, and the drive motor 1251 is started. The output shaft of the drive motor 1251 rotates, and the output shaft drives the cam 1252 to rotate. The cam 1252 can cooperate with the elastic member 1242 to drive the connecting plate 1261 to move in the vertical direction. The connecting plate 1261 drives the piston rod 1262 and the piston 1266 to move, so that the piston 1266 reciprocates in the cylinder 1263. When the piston 1266 moves downward, the air in the cylinder 1263 is pressed into the liquid storage tank 1212 through the air outlet one-way valve and the air outlet pipe 1264. When the piston 1266 moves upward, the cylinder 1263 draws air from the outside through the air inlet one-way valve and the air inlet pipe 1265. The continuous movement of the piston 1266 can continuously inflate the liquid storage tank 1212, so that the air pressure in the liquid storage tank 1212 increases, and the cleaning liquid in the liquid storage tank 1212 is pressed into the spray pipe 1211. The cleaning liquid is sprayed from the nozzle to the camera 13 to clean the lens surface of the camera 13.

[0078] At the same time, during the operation of the driving motor 1251, the output shaft drives the first sprocket 1231 to rotate, the first sprocket 1231 drives the second sprocket 1237 to rotate through the transmission chain 1232, the second sprocket 1237 drives the first bevel gear 1233 to rotate, the first bevel gear 1233 drives the second bevel gear 1234 to rotate, the second bevel gear 1234 drives the transmission gear 1236 to rotate, the transmission gear 1236 drives the ring gear 1238 to rotate, the ring gear 1238 drives the rotating ring 1222 to rotate, the rotating ring 1222 drives the arc-shaped mounting plate 1221 to rotate, the arc-shaped mounting plate 1221 drives the arc-shaped wiper block 1223 to rotate, and the arc-shaped wiper block 1223 cooperates with the cleaning fluid sprayed from the nozzle to clean the lens surface of the camera 13.

[0079] In addition, if Figure 1 , Figure 2 and Figure 3 As shown, the drone 1 of the embodiment of the utility model includes: a camera 13, a drone body 11 and a camera cleaning device 12.

In this case, the liquid storage tank 1212 can be set on the two second crossbars. In addition, the drone body 11 is provided with a guide groove 111 adapted to the plurality of guide blocks 1224, and the plurality of guide blocks 1224 are suitable for being slidably arranged in the guide groove 111.

[0082] In order to further improve the intelligence and automation level of the drone 1, in an optional embodiment, the drone 1 also includes a control mainboard, a detection sensor and a power component, and the camera 13, the power component, the drive assembly 125 and the detection sensor are all electrically connected to the control mainboard.

[0083] It should be noted that the control mainboard, as the core control unit of the drone 1, is responsible for receiving and processing signals from various components and issuing corresponding control instructions. The camera 13, power components, drive assembly 125 and detection sensors are all electrically connected to the control mainboard, ensuring real-time transmission and accurate processing of information.

[0084] Specifically, the camera 13 is responsible for capturing image information and transmitting this information to the control mainboard in real time. The power component is the power source of the drone 1, and it provides the necessary flight power for the drone 1 according to the instructions of the control mainboard. Through the electrical connection with the control mainboard, the power component can respond to the control instructions in real time to ensure the stable flight of the drone 1. The drive component 125 is a key component of the camera cleaning device 12. Through the electrical connection with the control mainboard, the drive component 125 can receive the control signal from the control mainboard and start or stop the work of the drive motor 1251 according to the instruction. The detection sensor is used to monitor the flight environment and working state of the drone 1, such as detecting parameters such as wind speed, air pressure, temperature, and environmental information. The detection sensor transmits the data monitored in real time to the control mainboard, providing important reference information for the flight control and cleaning work of the drone 1. The detection sensor may include an obstacle avoidance sensor.

[0085] In addition, the drone 1 inspection system of the embodiment of the utility model includes: a control center, a drone 1 hangar and a drone 1.

[0086] When in use, the control center controls the opening of the drone 1 warehouse, and then the control center gives a flight command. The control mainboard of drone 1 controls the power components to start, and drone 1 can take off from drone 1 warehouse. During the flight of drone 1, drone 1 inspects according to the established route. Drone 1 can detect obstacles in front and avoid them through obstacle avoidance sensors. Camera 13 will take pictures in real time and transmit real-time picture information to the command center through the 5G communication module to complete the inspection task.

[0087] The drone inspection system has the following functions:

[0088] (1) Unattended automated operation

[0089] It is deployed outdoors, and provides a suitable controlled environment and physical security inside to ensure the storage of drones (one drone can be stored in a single hangar). Automation technology is used to realize automatic opening and closing of the top cover and automatic lifting of the platform. The platform provides a take-off and landing site for drones, and realizes automatic launch and recovery of drones (after completing the mission, the drone is autonomously guided to land on the hangar platform and stored inside the hangar), and automatic charging (battery replacement) to meet high-frequency operation needs.

[0090] (2) UAV automated inspection

[0091] The drone communicates with the smart hangar and cloud system through a dedicated 5G module, receives tasks from the cloud system and takes off autonomously, achieves automatic obstacle avoidance, autonomous flight along the planned flight path, and autonomously adjusts flight attitude / gimbal angle / shooting distance / camera parameters, etc., and can efficiently complete inspection tasks issued by the cloud system.

[0092] (3) Remote scheduling of cloud systems

[0093] It is equipped with a cloud-based visual operating system and remote supervision, which enables cloud-based task planning (including inspection objects, execution time, etc.), remote task issuance, remote operation of drones, and exclusive account management. Front-end data is transmitted back to the cloud system in real time via 5G, and staff can view real-time data remotely and centrally monitor and control drones / smart hangars. Videos can be viewed on multiple devices / at multiple points.

[0094] The large-scale commercial use of 5G provides a basic guarantee for the implementation of this system. It fully utilizes the characteristics of 5G's large bandwidth, low latency, and wide connection, and uses the 5G network slicing function to achieve the reliability of drone low-altitude flight data transmission.

[0095] First, 5G's wide connectivity ensures that drones can perform automated tasks beyond visual range. The 5G network's secure and stable features can effectively avoid interference from civilian WiFi, high-rise buildings, and various radio frequency facilities during drone flight. The drone-specific network built with 5G slicing technology ensures the stability and continuity of data interaction between drones and control platforms.

[0096] Secondly, the large bandwidth of 5G makes it possible to transmit 4K / 8k ultra-high-definition video in real time. The original 4G network transmission bandwidth could not guarantee the clarity of the images transmitted by drones, which once became the biggest obstacle to remote dispatch of drones. The peak rate of 5G can reach 20Gbps, which effectively ensures that the data images collected by drones are transmitted back to the remote command center in real time, so that government staff can obtain clear on-site images at the first time.

[0097] There is no need for pilots to operate the drone. If the control center needs to temporarily interrupt the drone during its mission, such as giving the drone a command to hover or stretch the camera lens, the millisecond-level latency of 5G can maximize the synchronization of information between the drone site and the backend command center, maximizing the effect of being on the scene.

[0098] 5G edge computing can effectively solve the computational offloading and resource allocation problems of 5G networked drones. The various data collected by drones combined with different algorithms provide a wealth of decision-making basis for various business demand departments. According to the requirements of different businesses for latency and computing power, the tasks that need to be performed on the cloud, local, and MEC servers are separated. Then, for cloud and local tasks, they can be directly offloaded, while for tasks on MEC servers, the tasks are scheduled through the computational offloading and resource allocation algorithm based on reinforcement learning, and the total energy consumption of the system is minimized under the constraints of latency, computing power, etc.

[0099] Based on automatic flight observation, the research and deployment of visual AI recognition algorithms completes the aerial collection and identification of hidden dangers in the 5G smart hangar deployment area. For social governance, smart parks, and police applications, it can greatly reduce the time consumed by manpower to view, identify and manage events, and improve the efficiency of event discovery and handling.

[0100] The algorithm is deployed according to demand. The algorithm can be deployed in the cloud and connected to the real-time video stream to achieve real-time recognition and statistics during the flight. In addition, the algorithm can be deployed in the 5G module on the drone side to form edge computing, real-time recognition and real-time return of recognition results.
