Detailed Implementation

[0018] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0019] This invention provides an intelligent connected drone urban inspection device, such as... Figure 1-10 As shown, the intelligent connected drone urban inspection device includes: an intelligent connected drone body 1 and a housing 2, the housing 2 being mounted below the frame of the intelligent connected drone body 1; a panoramic camera 3 installed inside the housing 2 and adjustable for entry and exit; a passage 4 on the housing 2 for the panoramic camera 3 to enter and exit; a control mechanism on the housing 2 for controlling the opening and closing of the passage 4; an adjustment mechanism inside the housing 2 for regulating the entry and exit of the panoramic camera 3; and a cleaning mechanism inside the housing 2 for cleaning the lens glass of the panoramic camera 3 housed inside the housing 2.

[0020] In this embodiment, during use, the adjustment mechanism controls the panoramic camera 3 to enter and exit the housing 2 through the opening 4. In the shooting state, the panoramic camera 3 extends out of the housing 2 to collect urban inspection images. In the non-shooting state, the panoramic camera 3 retracts into the housing 2, and the control mechanism simultaneously controls the opening 4 to close, reducing the contact between external dust and debris and the lens glass of the panoramic camera 3. After the panoramic camera 3 is housed in the housing 2, the cleaning mechanism cleans its lens glass without the need for manual disassembly, simplifying the lens cleaning process and reducing maintenance difficulty. The main body 1 of the intelligent connected drone drives the housing 2 and internal components to fly stably. The housing 2 provides a protective space for the panoramic camera 3. With the cleaning function of the cleaning mechanism, it helps to maintain the cleanliness of the lens glass, ensure the quality of inspection image acquisition, and support the normal operation of urban inspection work.

[0021] In a further preferred embodiment of the present invention, the control mechanism includes: a baffle 5 slidably mounted on the housing 2 for blocking the opening 4; a connecting plate 7 fixed to the bottom end of the baffle 5; and an electric telescopic rod 6 fixed inside the housing 2, wherein the push rod of the electric telescopic rod 6 is fixedly connected to the connecting plate 7.

[0022] In this embodiment, when the panoramic camera 3 needs to extend out of the housing 2 to capture images, the push rod of the electric telescopic rod 6 extends and drives the connecting plate 7 to move. The connecting plate 7 drives the baffle 5 to slide on the housing 2, so that the opening 4 is opened, providing a channel for the panoramic camera 3 to extend. When the panoramic camera 3 retracts into the housing 2, the push rod of the electric telescopic rod 6 retracts in the opposite direction, and drives the baffle 5 to reset through the connecting plate 7, blocking the opening 4 and reducing the entry of external dust and debris into the housing 2 to contact the lens glass of the panoramic camera 3. The control mechanism adopts a cooperative structure of electric telescopic rod 6, connecting plate 7 and baffle 5, which can realize the opening and closing of port 4 without manual operation. It is convenient to operate and helps to improve the protective effect of the enclosure 2, and provides support for maintaining the cleanliness of the lens glass of panoramic camera 3.

[0023] In a further preferred embodiment of the present invention, the adjustment mechanism includes: a screw 8 rotatably mounted in the housing 2 via a bearing; an assembly frame 9 threaded onto the screw 8 for fixing the panoramic camera 3; and a guide rod 10 fixed in the housing 2, the guide rod 10 passing through the assembly frame 9.

[0024] In this embodiment, when it is necessary to adjust the panoramic camera 3 to enter or exit the housing 2, the screw 8 rotates in the housing 2 through the bearing, driving the threaded mounting bracket 9 to move axially along the screw 8, and the panoramic camera 3 moves synchronously with the mounting bracket 9 to extend out of the housing 2; when it is necessary to retract, the screw 8 rotates in the opposite direction, driving the mounting bracket 9 and the panoramic camera 3 back into the housing 2. During the movement of the assembly frame 9, the guide rod 10 passes through the assembly frame 9 and restricts its direction of movement, so that the assembly frame 9 drives the panoramic camera 3 to move smoothly and reduces the situation of deviation or shaking. The adjustment structure achieves the entry and exit control of the panoramic camera 3 through the forward and reverse rotation of the screw 8. With the limiting function of the guide rod 10, the action is smooth and the operation is stable, providing a reliable position adjustment guarantee for the image acquisition of the panoramic camera 3. In a further preferred embodiment of the present invention, the cleaning mechanism includes: a first rotating shaft 16 rotatably mounted in the housing 2 via a bearing; a cleaning brush 17 fixed on the first rotating shaft 16 for cleaning the lens glass of the panoramic camera 3; and a spray pipe 24 fixed in the housing 2 via a bracket for spraying cleaning liquid.

[0025] In this embodiment, after the panoramic camera 3 is retracted into the housing 2, the nozzle 24 sprays cleaning fluid onto the lens glass of the panoramic camera 3 to assist in subsequent cleaning operations. Then the first rotating shaft 16 rotates in the housing 2 through the bearing, which drives the cleaning brush 17 fixed thereto to rotate synchronously. The cleaning brush 17 contacts the lens glass and performs the cleaning operation. The cleaning mechanism adopts a cooperative structure of first rotating shaft 16, cleaning brush 17 and nozzle 24, which can complete the cleaning without manual disassembly of the lens. It is easy to operate and helps to remove dust and debris from the lens glass surface, thus supporting the image acquisition effect of panoramic camera 3.

[0026] In a further preferred embodiment of the present invention, the cleaning mechanism further includes a liquid supply mechanism for supplying cleaning liquid to the nozzle 24. The liquid supply mechanism includes: a storage tank 42 disposed in the housing 2 for holding the cleaning liquid; a liquid guide shell 19 fixed in the housing 2, the inlet of the liquid guide shell 19 being fixedly connected to the storage tank 42 via a liquid extraction pipe 23, and the outlet of the liquid guide shell 19 being fixedly connected to the inlet end of the nozzle 24; a second rotating shaft 20 rotatably mounted in the liquid guide shell 19 via a sealed bearing; and an impeller 21 fixed on the second rotating shaft 20.

[0027] In this embodiment, when the cleaning mechanism starts the cleaning operation, the second rotating shaft 20 rotates in the liquid guide shell 19 through the sealed bearing, which drives the impeller 21 fixed thereon to rotate synchronously, thereby generating a stable suction force. The suction effect generated by the impeller 21 causes the cleaning liquid in the storage tank 42 to flow into the liquid guide shell 19 along the liquid extraction pipe 23, and is continuously transported to the spray pipe 24 through the liquid outlet of the liquid guide shell 19, providing power support for the spray pipe 24 to spray the cleaning liquid. The nozzle 24 sprays out the received cleaning fluid, causing the cleaning fluid to fall onto the lens glass of the panoramic camera 3 and the bristles of the cleaning brush 17, creating favorable conditions for the cleaning brush 17 to clean the lens glass subsequently.

[0028] In a further preferred embodiment of the present invention, a driving mechanism is provided inside the housing 2 for driving the first rotating shaft 16, the second rotating shaft 20, and the screw 8 to rotate. The driving mechanism includes: a motor 11 fixed inside the housing 2; a splined cylinder 12 rotatably mounted inside the housing 2 via a bearing seat, the top end of the splined cylinder 12 being fixedly connected to the output shaft of the motor 11 via a coupling; a splined rod 13 rotatably mounted on the connecting plate 7 via a bearing seat, the top end of the splined rod 13 being inserted into the splined cylinder 12; a first bevel gear 14 and a second bevel gear 15 respectively fixed to the splined rod 13 and the screw 8 and capable of meshing with each other; a third bevel gear 18 respectively fixed to the first rotating shaft 16 and the splined rod 13 and meshing with each other; and a fourth bevel gear 22 respectively fixed to the splined rod 13 and the second rotating shaft 20 and meshing with each other.

[0029] In this embodiment, when it is necessary to adjust the panoramic camera 3 to extend out of the housing 2, the push rod of the electric telescopic rod 6 extends and drives the connecting plate 7 to descend. The spline rod 13 descends synchronously with the connecting plate 7, so that the fourth bevel gear 22 on the spline rod 13 separates from the second rotating shaft 20 and the third bevel gear 18 separates from the first rotating shaft 16. After the passage 4 is opened, the electric telescopic rod 6 stops running. At this time, the first bevel gear 14 on the spline rod 13 meshes with the second bevel gear 15 on the screw 8. After the motor 11 is started, its output shaft drives the splined cylinder 12 to rotate, the splined cylinder 12 drives the splined rod 13 to rotate, and the screw 8 is driven to rotate through the meshing transmission of the first bevel gear 14 and the second bevel gear 15, which in turn drives the assembly frame 9 to move with the screw 8 and protrude from the through port 4, thereby realizing the extension control of the panoramic camera 3. When the panoramic camera 3 is in the retracted state, the first bevel gear 14 and the second bevel gear 15 are separated, the third bevel gear 18 on the spline rod 13 meshes with the first rotating shaft 16, and the fourth bevel gear 22 meshes with the second rotating shaft 20. Power is provided by the same motor 11, realizing the orderly switching of the driven object, providing stable power for the cleaning action of the cleaning mechanism, and simplifying the power structure of the device.

[0030] In a further preferred embodiment of the present invention, a collection hopper 25 for collecting sewage is fixed inside the box 2, and a sewage pipe 26 is fixedly connected to the bottom of the collection hopper 25. A first solenoid valve 27 is provided on the sewage pipe 26.

[0031] In this embodiment, when the cleaning mechanism cleans the lens glass of the panoramic camera 3, the panoramic camera 3 maintains the posture adapted to cleaning. The cleaning liquid will drip down naturally, and the collection bucket 25 will collect the dripping liquid to prevent the liquid from accumulating in the box 2 and to prevent the liquid from invading the shooting direction adjustment structure of the panoramic camera 3, thus ensuring its normal function. When the amount of sewage in the collection hopper 25 reaches a certain level, the first solenoid valve 27 can be opened to allow the sewage in the collection hopper 25 to be discharged to the outside of the box 2 through the drain pipe 26. The coordinated arrangement of the collection hopper 25, the drain pipe 26, and the first solenoid valve 27 enables the centralized collection and orderly discharge of cleaning wastewater, reducing the impact of wastewater on the internal components of the housing 2, supporting the cleanliness of the device's interior, and indirectly ensuring the stable operation of the panoramic camera 3's built-in functions.

[0032] In a further preferred embodiment of the present invention, a connecting frame 40 is symmetrically fixed below the frame of the main body 1 of the intelligent connected drone, and a connecting seat 41 adapted to the connecting frame 40 is symmetrically fixed on the top of the box 2. The bottom end of the connecting frame 40 is T-shaped, and a T-shaped groove is provided on the connecting seat 41.

[0033] In this embodiment, when installing the housing 2, align the T-shaped groove on the connector 41 with the connector frame 40 below the main body 1 of the intelligent connected drone, push the housing 2 along the direction of the T-shaped groove so that the T-shaped connector frame 40 is embedded in the T-shaped groove of the connector 41, and then fix it by tightening the bolts.

[0034] In a further preferred embodiment of the present invention, a stirring rod 37 is rotatably mounted in the liquid storage tank 42 via a bearing for stirring the cleaning liquid. The stirring rod 37 and the splined cylinder 12 are respectively fixed with pulleys 38, and a transmission belt 39 is sleeved on the corresponding pulleys 38.

[0035] In this embodiment, when the motor 11 starts and drives the splined cylinder 12 to rotate, the pulley 38 on the splined cylinder 12 rotates synchronously, and drives the pulley 38 on the stirring rod 37 in the liquid storage tank 42 to rotate through the transmission belt 39, thereby driving the stirring rod 37 to rotate in the liquid storage tank 42. The stirring rod 37 stirs the cleaning solution in the storage tank 42 during rotation, which helps to prevent the precipitation of the effective ingredients in the cleaning solution and maintain the cleaning effect of the cleaning solution.

[0036] In a further preferred embodiment of the present invention, the top of the liquid storage tank 42 is provided with a liquid replenishment port, a detachable cover plate is provided inside the liquid replenishment port, a pull ring is fixedly installed on the cover plate, and a door is assembled on one side of the tank body 2 by a hinge, and a door lock is provided on the door.

[0037] In this embodiment, when the cleaning fluid in the storage tank 42 is insufficient, the door can be opened, the pull ring can be held to remove the cover plate inside the replenishment port, and the cleaning fluid can be replenished into the storage tank 42 through the replenishment port. After replenishment, the cover plate can be put back into the replenishment port. The combination of the replenishment port and the cover plate facilitates timely replenishment of cleaning fluid, and the pull ring design improves the ease of disassembly and assembly of the cover plate; the configuration of the door and lock facilitates the inspection and maintenance of the internal components of the enclosure 2, helps to improve the maintenance efficiency of the device, and ensures the stable operation of each mechanism.

[0038] To further improve the performance of this device, in addition to the above-mentioned solutions, this solution also includes the following embodiments: In another embodiment of the present invention, a hot air supply mechanism is provided inside the housing 2 for blowing out hot air to remove water stains. The hot air supply mechanism includes: a hot air blower 28 fixed inside the housing 2, a diverter pipe 29 fixedly connected to the air outlet of the hot air blower 28, a first air outlet pipe 30 fixedly connected to the air blowing end of the diverter pipe 29, a first air diffuser 31 fixedly connected to the air outlet end of the first air outlet pipe 30, the first air diffuser 31 facing the cleaning brush 17, a second solenoid valve 35 provided on the first air outlet pipe 30, an air inlet opened on one side of the housing 2, and a dust filter plate provided inside the air inlet.

[0039] In this embodiment, after the cleaning mechanism completes the cleaning of the lens glass of the panoramic camera 3, it can start the hot air blower 28 and open the second solenoid valve 35 at the same time. The hot air generated by the hot air blower 28 is delivered to the first air outlet pipe 30 through the diversion pipe 29, and then blown towards the cleaning brush 17 and the lens glass surface through the first air diffuser 31. Hot air acts on the lens glass and cleaning brush 17, which can remove residual water stains from the surface, reduce the impact of water stains on subsequent shooting, and help keep the cleaning brush 17 dry.

[0040] In another embodiment of the present invention, a shielding shell 32 is fixedly installed on one side of the housing 2 for sunshading the panoramic camera 3 protruding outside the housing 2. A second air outlet pipe 33 is fixedly connected to the diverter pipe 29. The air outlet end of the second air outlet pipe 33 extends into the shielding shell 32. A second air diffuser 34 is fixedly connected to the air outlet end of the second air outlet pipe 33 for blowing air to drive away flying insects and reduce impurities adhering to the lens glass of the panoramic camera 3. A third solenoid valve 36 is provided on the second air outlet pipe 33.

[0041] In this embodiment, when the panoramic camera 3 extends out of the housing 2 to collect images, the shielding shell 32 is located on the side of the panoramic camera 3 to provide sun protection for the lens glass and reduce the impact of direct sunlight on shooting.

[0042] When it is necessary to drive away flying insects or reduce the attachment of impurities, the hot air blower 28 can be started and the third solenoid valve 36 can be opened without turning on the heating unit in the hot air blower 28, so that the normal temperature airflow is delivered to the second air diffuser 34 through the diversion pipe 29 and the second air outlet pipe 33. The second diffuser 34 blows ambient airflow to the periphery of the lens glass, forming an airflow barrier. This helps to drive away flying insects, reduce the adhesion of impurities, and ensure the cleanliness of the lens glass, thus providing support for the panoramic camera 3 to stably acquire images.

[0043] The combination of the shielding shell 32 with the second air outlet duct 33 and the second air diffuser 34 not only provides sun protection, but also drives away flying insects and reduces the adhesion of impurities through airflow, thus providing support for the panoramic camera 3 to stably acquire clear images.

[0044] In summary, compared with related technologies, the intelligent connected drone body 1 drives the housing 2 to fly stably, and the panoramic camera 3 moves in and out of the housing 2 with the help of the adjustment mechanism. The opening and closing of the opening 4 is achieved with the help of the control mechanism, which reduces the contact between external impurities and the lens glass. After being put into the housing 2, the cleaning mechanism completes the cleaning of the lens glass with the power support of the drive mechanism, the liquid supply mechanism ensures a stable supply of cleaning liquid, and the collection hopper 25 and the sewage pipe 26 realize the orderly discharge of sewage. At the same time, the hot air supply mechanism, the shielding shell 32 and other components further improve the cleaning effect and protection capability. The overall structure, through the coordinated cooperation of various mechanisms, can maintain the cleanliness of the lens glass of the panoramic camera 3 without frequent manual operation, ensuring the quality of inspection image acquisition and providing support for the efficient development of urban inspection work.

[0045] It is worth noting that in this invention, the shooting direction adjustment function of the panoramic camera 3 is implemented using existing mature technology. Its specific structure (such as the built-in drive motor, angle sensor, etc.) is not the key improvement point of this invention. The power and execution components involved in this device are all lightweight and low-power models adapted to the working conditions of the drone, ensuring that the overall weight of the device is controllable and does not affect the flight stability and endurance of the intelligent connected drone body 1. Among them, the motor 11 in the drive mechanism is a micro DC servo motor with a rated voltage of 24V and a power range of 50-80W. It has the characteristics of adjustable speed and stable torque. Its output shaft is connected to the spline cylinder 12 through a flexible coupling, which can effectively buffer the impact force during rotation and avoid jamming or wear when the bevel gear meshes. The motor 11 is fixed to the motor bracket inside the housing 2 by bolts. The bracket is made of aluminum alloy and is integrally formed, which is both lightweight and vibration resistant. It can reduce the impact of vibration generated during the flight of the UAV on the operating accuracy of the motor 11, ensure the meshing transmission stability of the spline cylinder 12, spline rod 13 and each bevel gear, and realize the precise drive switching of the screw 8, the first rotating shaft 16 and the second rotating shaft 20.

[0046] The hot air supply unit's hot air blower 28 uses an integrated hot air module with a built-in low-noise fan and PTC heating element. With a rated power of 100-150W, it can switch between ambient temperature air supply and hot air output. The hot air temperature can be controlled between 40-60℃, quickly removing water stains from the lens glass surface without damaging the panoramic camera 3's lens coating or internal electronic components due to excessive temperature. The air inlet of the hot air blower 28 is aligned with the air inlet on the side of the housing 2. The dust filter inside the air inlet is made of high-density non-woven fabric, filtering dust, particulate matter, and other impurities from the air, preventing impurities from entering the hot air blower 28 or being blown onto the lens glass, further ensuring cleaning effectiveness and equipment safety.

[0047] In addition, the electric telescopic rod 6 uses a miniature electric push rod with a stroke range of 50-80mm, a rated thrust of 500N, and a DC 12V power supply. Its operating noise is below 45dB. The end of the push rod is fixed to the connecting plate 7 via threads. Combined with the slider guide rail structure, it can drive the baffle 5 to slide smoothly, achieving rapid opening and closing of the port 4. The first solenoid valve 27, the second solenoid valve 35, and the third solenoid valve 36 are all normally closed electromagnetic directional valves, suitable for the delivery of cleaning fluid and airflow. Their working pressure range is 0.1-0.3MPa, and the response time is ≤0.5s. Their switching states can be precisely controlled by the UAV's control system, achieving orderly control of sewage discharge, hot air delivery, and ambient temperature airflow delivery. All electrical components are connected to the UAV's main control system and power module via waterproof connectors. Key electrical connections inside the housing 2 are sealed with waterproof adhesive, providing IP54 waterproof and dustproof capabilities. This allows them to adapt to complex weather conditions during urban inspections, preventing rainwater and dust intrusion that could cause component failure.

[0048] The selection and adaptation design of the above-mentioned components are all based on the actual working conditions of UAV urban inspection. While ensuring the stable functioning of each mechanism, they also take into account lightweight, low power consumption, vibration resistance and sealing, so that the device can adapt to urban inspection work under different climatic conditions, improving the practicality and reliability of the device. At the same time, all components adopt standardized specifications, which facilitates subsequent maintenance, replacement and mass production, meeting the needs of the industrial application of patented technology. Moreover, the circuits, electronic components and modules involved are all existing technologies, which can be fully implemented by those skilled in the art, and need not be elaborated. The content protected by this invention does not involve the improvement of software and methods.

[0049] It should be understood, in the several embodiments provided in this application, that the disclosed apparatus may be implemented in other ways.

[0050] The above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit the scope of protection of the invention.

Based on these embodiments, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
