Description
Technical Field
[0001] This utility model belongs to the field of unmanned aerial vehicle (UAV) structural technology, specifically relating to a waterproof and dustproof structure for an inspection UAV. Background Technology
[0002] A drone is an unmanned aircraft controlled by radio remote control equipment and its own program control device. Drones are equipped with many control units and precision instruments such as sensors. The control unit, as an essential component, is usually located inside a protective shell and connected to these precision instruments via data cables or wires. Depending on actual needs, drones may add or remove certain sensors. If a sensor is added and the shell has too few mounting holes, additional mounting holes must be made on the shell. If sensors are removed during use, the extra mounting holes are exposed, allowing moisture or dust to enter the control unit and damage it.
[0003] To address this, a waterproof and dustproof device for a drone, with publication number "CN209506110U", includes a flexible protective plug and a housing for housing a microcomputer. The housing has mounting holes that match the shape of the flexible protective plug, which is then inserted into the mounting holes. By first creating mounting holes on the housing and then sealing them with flexible protective plugs, the device achieves waterproofing and dustproofing. When a specific mounting hole is needed, the corresponding flexible protective plug is simply modified. The structure is simple and easy to use.
[0004] However, although the waterproof and dustproof devices for the aforementioned drones achieve waterproofing and dustproofing by first opening mounting holes on the shell and then sealing the mounting holes with flexible protective plugs, the following obvious defects still exist during use: the waterproof and dustproof devices of the aforementioned aircraft keep the control unit in a sealed space, and all openings are sealed by flexible protective plugs. Therefore, the control unit in the aircraft is prone to high temperatures when working in the sealed space, and the heat cannot be dissipated and the cool air can enter to cool it down. This makes the inspection aircraft prone to frequent failures due to high temperatures during operation. Utility Model Content
[0005] The purpose of this invention is to provide a waterproof and dustproof structure for inspection unmanned aerial vehicles to solve the problems mentioned in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a waterproof and dustproof structure for an inspection unmanned aerial vehicle, comprising:
[0007] The unmanned aerial vehicle (UAV) body has a magnetically sealed cover at its end, which facilitates battery installation and maintenance during inspection. Water baffles are installed at equal intervals from top to bottom through dustproof mesh panels in the openings on both sides of the UAV body. Rotary rotors extend outward from the four corners of the outer side of the UAV body for mounting the flight blades and drive motors. A foldable tarpaulin is provided around the outer perimeter of the UAV body, which can elastically retract and unfold to block dust and water splashed during UAV takeoff and landing. A sliding locking sleeve is mounted on the rotor rotor to unfold and lock the foldable tarpaulin.
[0008] Preferably, ventilation slots are provided on both sides of the exterior of the unmanned aerial vehicle body, and dustproof mesh plates are vertically installed inside the ventilation slots. On the one hand, this can effectively block external dust, debris and other objects from entering the body and prevent them from damaging electronic components. On the other hand, the vertically installed dustproof mesh plates can minimize the obstruction of airflow while ensuring ventilation, ensuring that air can pass smoothly through the ventilation slots and achieve efficient heat dissipation.
[0009] Preferably, the water baffle is stacked at equal intervals in the ventilation slot, and the water baffle is fixed at equal intervals on the dustproof mesh plate in the ventilation slot. The end of the water baffle located outside the unmanned aerial vehicle body has a downwardly stacked and inclined structure.
[0010] Preferably, the dustproof mesh and the inclined, stacked, and fixed water-blocking plate form a flow channel that provides waterproofing, dustproofing, and ventilation, preventing water from directly entering the ventilation slots and thus damaging the electronic components inside the drone. The structure of the water-blocking plates being stacked and inclined downwards at equal intervals at one end of the drone's exterior further enhances the waterproofing effect.
[0011] Preferably, a locking rod is threaded through the sliding lock sleeve, and one end of the locking rod is attached to the rotary blade rod to slide and lock the sliding lock sleeve. The four corners of the folded rain cloth are fixed to the ends of the sliding lock sleeve, which can effectively filter out larger particles of impurities such as dust and sand carried in the air, ensuring that the air entering the circulation channel is relatively clean. The inclined and stacked water baffles play a key role in waterproofing.
[0012] Preferably, the unmanned aerial vehicle (UAV) has a magnetic sealing groove around its end, and a sealing ring is provided at the lower end of the magnetic cover plate corresponding to the magnetic sealing groove. Magnetic blocks are evenly embedded in the lower surface of the sealing ring to ensure good waterproof and dustproof performance. Moreover, when the battery needs to be removed or repaired, the magnetic cover plate can be easily opened by overcoming the magnetic force, making the operation simple and convenient and greatly improving the efficiency of equipment maintenance.
[0013] Preferably, the unmanned aerial vehicle (UAV) is equipped with an inspection camera with a protective sealing cover at the bottom of its body, and landing gear is provided on the side of the bottom of the UAV. The UAV body is equipped with a removable battery pack and control unit. The removable battery pack and control unit are provided inside the UAV body, which facilitates battery replacement and equipment maintenance.
[0014] Compared with existing technologies, the technical effects and advantages of this utility model are: the waterproof and dustproof structure of this inspection unmanned aerial vehicle...
[0015] This invention effectively solves the problem by creating ventilation slots on both sides of the unmanned aerial vehicle (UAV) and vertically installing dustproof mesh panels within them. The dustproof mesh panels effectively block dust and debris while ensuring smooth airflow for efficient heat dissipation. Simultaneously, water deflectors are stacked at equal intervals and angles within the ventilation slots, forming a waterproof, dustproof, and ventilated channel with the dustproof mesh panels. This ensures good heat dissipation while preventing water from entering the internal structure and damaging electronic components, achieving a balance between heat dissipation and waterproofing / dustproofing. This significantly improves the stability and reliability of the inspection UAV and reduces frequent malfunctions caused by high temperatures.
[0016] This invention features a magnetically sealed cover at the end of the drone's fuselage. This cover, in conjunction with a magnetic sealing groove, sealing ring, and magnetic block at the end of the fuselage, ensures excellent waterproof and dustproof performance. Furthermore, it can be easily opened by overcoming magnetic force when the battery needs to be installed or removed for maintenance, making operation simple and convenient and improving equipment maintenance efficiency. In addition, the sliding lock sleeve and folding rain cover design effectively block dust and water during takeoff and landing, and the folding rain cover can be flexibly controlled by the locking lever. The drone's internal fuselage houses separate battery pack and control components, facilitating battery replacement and equipment maintenance, further enhancing the equipment's practicality and operability.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0023] Please see Figure 1-4 This utility model provides a technical solution: a waterproof and dustproof structure for an inspection unmanned aerial vehicle, comprising:
[0024] The unmanned aerial vehicle (UAV) body 1 ensures the orderly placement of internal components such as the removable battery pack 16 and control unit 17, and achieves good connection and cooperation with external components such as the rotor rod 5 and the magnetic cover 2. The end of the UAV body 1 is equipped with a magnetically sealed cover 2, facilitating battery removal and maintenance during inspection. Firstly, the magnetic seal ensures a relatively sealed space inside the aircraft, effectively preventing the entry of external dust and moisture, providing reliable protection for internal electronic components. Secondly, this design greatly facilitates battery removal and maintenance during inspection. When battery replacement or internal component maintenance is required, the cover can be easily opened by overcoming the magnetic force, making the operation simple and quick, and improving equipment maintenance efficiency.
[0025] Water deflectors 4 are installed at equal intervals and inclined downwards through the dustproof mesh panels 3 in the openings on both sides of the unmanned aerial vehicle (UAV) body 1. These water deflectors 4 are an important component of the waterproof and dustproof structure. They effectively prevent larger particles such as dust and debris from entering the interior of the UAV body, avoiding damage such as wear and short circuits to electronic components. Simultaneously, their vertical arrangement ensures ventilation while minimizing airflow obstruction, allowing cool outside air to smoothly pass through the ventilation slots 8 and enter the interior of the UAV body for heat exchange with the heat-generating components, achieving efficient heat dissipation. When rainwater or water splashed during takeoff and landing comes into contact with the ventilation slots 8, the water deflectors 4 guide the water flow down the inclined surface, preventing water from directly entering the ventilation slots 8 and damaging the internal electronic components. An additional structure, located at one end of the UAV body 1 and equidistantly inclined downwards, further enhances the waterproof effect. The multi-layered baffle 4 acts as a barrier and guide, making it more difficult for water to enter the ventilation slot 8, while not excessively obstructing airflow, thus ensuring that the ventilation and heat dissipation functions are not affected.
[0026] The unmanned aerial vehicle (UAV) body 1 has four outward-extending rotor rods 5 at its four corners for mounting the flight blades and drive motors. These rotor rods provide a stable support structure for the flight blades and drive motors, ensuring that the drive motors can reliably rotate the flight blades during flight, providing lift and power to the aircraft. Simultaneously, the rotor rods 5 cooperate with the sliding lock sleeves 7 to provide a slide rail for the unfolding and folding of the folded tarpaulin 6, allowing it to effectively block dust and water when needed. The outer perimeter of the UAV body 1 features a folded tarpaulin 6 that elastically contracts and unfolds to block dust and water splashed during the UAV's takeoff and landing. During takeoff and landing, dust and potential water on the ground are easily splashed up. The unfolded tarpaulin 6 forms an effective barrier, preventing this dust and water from splashing onto the aircraft body, especially preventing it from entering critical areas such as the ventilation slots 8 and the interior of the UAV body 1, thereby enhancing the aircraft's waterproof and dustproof capabilities. When the aircraft is in flight, the folding tarp 6 can be retracted and stored to reduce its impact on flight.
[0027] The rotary blade rod 5 is equipped with a sliding locking sleeve 7, which locks the unfolding and folding of the folded tarpaulin 6. The sliding locking sleeve 7 plays a crucial control role in the unfolding and folding of the folded tarpaulin 6. By sliding on the rotary blade rod 5, the sliding locking sleeve 7 can adjust the degree of unfolding of the folded tarpaulin 6 to adapt to different take-off and landing environments. The locking rod 10, threaded through the sliding locking sleeve 7, can lock the sliding locking sleeve 7 onto the rotary blade rod 5 after it has moved to the appropriate position, ensuring that the folded tarpaulin 6 remains stable in both unfolded and folded states. In addition, the four corners of the folded tarpaulin 6 are fixed to the ends of the sliding locking sleeve 7, ensuring the stability and reliability of the folded tarpaulin 6 during movement.
[0028] Ventilation slots 8 are provided on both sides of the exterior of the unmanned aerial vehicle (UAV) body 1, and dustproof mesh panels 3 are vertically installed inside the ventilation slots 8. The ventilation slots 8, located on both sides of the exterior of the UAV body 1, provide channels for air circulation. Cold outside air enters the interior of the UAV body through the ventilation slots 8, exchanges heat with the heat-generating electronic components, and then the hot air is discharged through the ventilation slots 8, achieving heat dissipation inside the UAV body. The ventilation slots 8, together with the dustproof mesh panels 3 and the water deflectors 4, effectively prevent dust and water from entering the interior of the UAV body while ensuring ventilation and heat dissipation. This allows the UAV to maintain a good thermal balance under waterproof and dustproof conditions, ensuring the normal operation of the electronic components.
[0029] The water-blocking plates 4 are stacked at equal intervals and inclined within the ventilation slots 8, and are also fixed at equal intervals and inclined on the dustproof mesh plates 3 within the ventilation slots 8. The end of the water-blocking plates 4 located outside the unmanned aerial vehicle (UAV) body 1 has a downward-facing, equidistantly stacked, inclined structure. A flow channel 9, providing waterproofing, dustproofing, and ventilation, is formed between the dustproof mesh plates 3 and the inclined, stacked, fixed water-blocking plates 4. This flow channel 9 is an important structure integrating waterproofing, dustproofing, and ventilation functions. The dustproof mesh plates 3, as the first layer of protection, filter out larger particles such as dust and sand carried in the air, ensuring relatively clean air entering the flow channel 9. The inclined, stacked water-blocking plates 4 play a crucial role in waterproofing, preventing water from entering layer by layer. Simultaneously, this channel ensures airflow, allowing air to flow smoothly and achieving heat dissipation, providing a good working environment for the electronic components inside the UAV, thus meeting the requirements of waterproofing, dustproofing, and heat dissipation.
[0030] A locking rod 10 is threaded through the sliding lock sleeve 7, and one end of the locking rod 10 is attached to the rotary blade 5 to slide and lock the sliding lock sleeve 7. The four corners of the folded tarpaulin 6 are fixed to the ends of the sliding lock sleeve 7. The locking rod 10 is threaded through the sliding lock sleeve 7, and one end is attached to the rotary blade 5. By rotating the locking rod 10, the degree of contact between it and the rotary blade 5 can be changed, thereby locking and unlocking the sliding position of the sliding lock sleeve 7 on the rotary blade 5. When it is necessary to adjust the unfolded or folded state of the folded tarpaulin 6, the locking rod 10 is released, and the sliding lock sleeve 7 can slide freely on the rotary blade 5; after adjusting to the appropriate position, the locking rod 10 is tightened to make it fit tightly against the rotary blade 5, and the sliding lock sleeve 7 is firmly locked to ensure that the folded tarpaulin 6 is kept in the desired state.
[0031] A magnetic sealing groove 11 is provided around the end of the unmanned aerial vehicle (UAV) body 1. The magnetic sealing groove 11 cooperates with the sealing ring 12 and magnetic block 13 at the lower end of the magnetic cover plate 2. This provides precise positioning for the magnetic cover plate 2, allowing the cover to accurately close onto the end of the body. At the same time, the magnetic force between the magnetic sealing groove 11 and the magnetic block 13 enhances the sealing effect, ensuring that external dust, moisture, etc., cannot enter the interior of the UAV, providing reliable waterproof and dustproof protection for the internal electronic components. Furthermore, the sealing ring 12 is provided at the lower end of the magnetic cover plate 2 corresponding to the position of the magnetic sealing groove 11, which can fill the tiny gap between the magnetic cover plate 2 and the end of the UAV body 1. It further enhances the sealing performance, working together with the magnetic block 13 and the magnetic sealing groove 11 to effectively prevent dust, moisture, and other contaminants from entering the aircraft, improving the waterproof and dustproof effect and protecting the internal electronic components from the influence of the external environment. Furthermore, the magnetic block 13 is evenly embedded in the lower end face of the sealing ring 12, and the magnetic block 13 and the magnetic sealing groove 11 attract each other, causing the magnetic cover 2 to tightly close to the end of the unmanned aerial vehicle body 1. This magnetic connection method not only provides excellent sealing performance, but also allows for easy operation by overcoming magnetic force when the magnetic cover 2 needs to be opened for battery removal, installation, or maintenance, making it convenient and quick, and improving the ease of equipment maintenance.
[0032] The unmanned aerial vehicle (UAV) body 1 is equipped with an inspection camera 14 with a protective sealing cover at its bottom. The protective cover protects the inspection camera 14 from external dust, moisture, collisions, and other factors, ensuring that the camera can operate normally and stably acquire clear inspection images or video data in various complex environments. This data is crucial for inspection tasks. For example, in power line inspections, the camera can capture the operating status of lines, poles, and other equipment, providing a basis for subsequent maintenance decisions. The UAV body 1 also has landing gear 15 on its bottom side. Inside the UAV body 1 are a removable battery pack 16 and a control unit 17. The removable battery pack 16, housed inside the UAV body 1, provides power for the aircraft's flight. Its removable design facilitates battery replacement; when the battery is depleted, it can be quickly replaced with a fully charged battery, ensuring the inspection UAV can continue to perform tasks and improving equipment efficiency and endurance. Simultaneously, this design also facilitates individual battery maintenance, upkeep, and testing, allowing for the timely detection of potential battery problems.
[0033] Control unit 17 is responsible for the comprehensive control and management of the aircraft's flight attitude, sensor data processing, and mission execution. It connects to various sensors and actuators on the aircraft via data cables or wires, receiving and processing various information, issuing corresponding commands, and ensuring that the aircraft can fly stably according to the predetermined program and mission requirements, and accurately complete the inspection task. The stable operation of control unit 17 is crucial to the performance and reliability of the entire inspection UAV, while the waterproof and dustproof structure of the airframe provides a good working environment guarantee.
[0034] Specifically, during use, the end of the UAV body 1 engages with the sealing ring 12 and magnetic block 13 at the lower end of the magnetic cover plate 2 via a magnetic sealing groove 11. Magnetic attraction ensures a tight seal, and the sealing ring 12 fills any gaps, effectively preventing external dust and moisture from entering, providing reliable protection for internal components and facilitating battery removal and maintenance. Dustproof mesh plates 3 are vertically installed in the ventilation slots 8 on both sides of the UAV body 1, with water-blocking plates 4 stacked at equal intervals on top, forming a circulation channel 9 that integrates waterproofing, dustproofing, and ventilation. The dustproof mesh plates 3 filter larger particles, while the water-blocking plates 4 prevent water stains and ensure airflow for heat dissipation. Cold outside air enters the body through the ventilation slots 8, exchanges heat with the heating elements, and is then discharged, maintaining thermal balance and ensuring the normal operation of electronic components. During UAV takeoff and landing, ground dust and water can easily splash up; at this time, the unfolded folded tarpaulin 6 forms a barrier around the outside of the UAV body 1, preventing dust and water from splashing onto critical parts of the aircraft. The sliding lock sleeve 7 on the rotor rod 5 adjusts the unfolding degree of the folded rain cloth 6 by sliding on the rotor rod 5. The locking rod 10 can lock the sliding lock sleeve 7 in the appropriate position. During flight, the folded rain cloth 6 can be retracted and stored. The inspection camera 14 at the bottom of the UAV body 1 is equipped with a protective sealing cover to resist external dust, moisture and impact, ensuring normal acquisition of inspection data. The internal removable battery pack 16 provides power to the aircraft, and its removable design facilitates replacement, maintenance and inspection. The control unit 17 is responsible for the comprehensive control and management of the aircraft's flight attitude, data processing and mission execution. The waterproof and dustproof structure provides a good environmental guarantee for its stable operation.
