Description

Technical Field

[0001] This utility model relates to the field of unmanned airship technology, and in particular to an unmanned airship for detection. Background Technology

[0002] Aerial reconnaissance platforms are in high demand in fields such as aerial patrol and monitoring, scientific research and exploration, and remote sensing and mapping. Among traditional reconnaissance methods, UAVs have high flexibility, but their loiter time is usually only a few hours due to the limitation of battery energy density, and their flight stability is insufficient in complex weather conditions. As a lighter-than-air aircraft, unmanned airships have the characteristics of long loiter time, stable payload capacity, and low energy consumption, thus promoting the development of unmanned airship technology.

[0003] However, existing unmanned airships usually have many shortcomings. For example, unmanned airships rely on battery packs for power, but the energy density of batteries is low, which limits their endurance and leads to frequent recovery and recharging for long missions. Unmanned airships mainly rely on airbag buoyancy to maintain their flight and are equipped with only a single propulsion device, which results in insufficient flight stability in complex environments. Traditional detection devices are mostly fixed-view cameras, which cannot adapt to diverse mission requirements. At the same time, the cameras lack protective measures and are prone to blurry images due to lens contamination or fogging in environments such as rain, fog, and dust, which affects the reliability of detection.

[0004] Therefore, it is necessary to improve the structure of existing unmanned airships to ensure output power and minimize environmental pollution, while also enhancing endurance to meet the requirements of long-duration, long-distance flight missions, improving flight stability, and installing protective devices around the detection equipment to ensure successful detection missions even in harsh environments, thereby improving the reliability of detection. Utility Model Content

[0005] In view of the current shortcomings of unmanned airships, the purpose of this utility model is to provide an unmanned airship for detection that can improve endurance while ensuring output power and causing less pollution to the environment, meet the needs of long-term and long-distance flight missions, enhance flight stability, and set up protective devices around the detection device so that it can successfully complete the detection mission in harsh environments, thereby improving the reliability of detection.

[0006] To achieve the purpose of this utility model, the present utility model provides an unmanned airship for detection, comprising:

A torque spring is sleeved on the torque spring shaft, with one end of the torque spring fixed to the left cover and the other end fixed to the right cover. The lens extends out of the protective cover, and the compression of the torque spring causes the left cover and the right cover to rotate outward about the torque spring shaft.

[0021] The auxiliary lift motor and tail thrust motor can be controlled to start or stop.

[0022] Furthermore, the airbag is installed on the top of the machine body, and a flexible solar panel is laid around the top of the airbag;

[0023] It also includes a battery pack, which is fixed inside the body and connected to a flexible solar panel for charging.

[0024] Furthermore, it also includes a data transmission unit, which is used to transmit image data, location data and environmental parameters of the detection area to the ground control station.

[0034] The following is in conjunction with the appendix Figure 1-7The present invention will be described in further detail below.

[0035] This utility model embodiment discloses an unmanned airship for detection, comprising:

[0036] The hull comprises a fuselage 1 and airbags 2. The fuselage 1 is typically made of lightweight, high-strength composite materials, such as carbon fiber reinforced composites, which reduces overall weight while ensuring sufficient structural strength and rigidity. An independent compartment is located inside the fuselage 1 for installing motor units, functional modules, and other necessary equipment and components, which will not be elaborated further here. The airbags 2 are typically made of flexible and airtight materials, such as polyvinyl chloride (PVC) or polyurethane (PU) coated fabrics, ensuring good sealing performance. The airbags 2 are filled with helium, providing stable buoyancy for the unmanned airship. The shape of the airbags 2 is generally approximately elliptical, which ensures a large volume while providing good aerodynamic performance, which will not be elaborated further here.

[0037] Data acquisition unit 3, installed on the main body 1, is used to acquire image data and environmental parameters of the detection area. The data acquisition unit 3 simultaneously acquires image data and environmental parameters of the detection area, such as temperature, humidity, light intensity, or gas concentration, achieving three-dimensional monitoring of the detection area and avoiding the limitations of single data sources. The data acquisition unit 3 can continuously acquire real-time data at a preset frequency, promptly detecting abnormal dynamics in the detection area, such as initial smoke in a fire or equipment malfunction warnings, shortening response time. The design of integrating the data acquisition unit 3 into the main body 1 allows for optimized layout based on application needs, adapting to complex environments, ensuring the stability and continuity of data acquisition, providing raw data for subsequent data processing, such as image recognition, big data analysis, or AI modeling, supporting automated decision-making. Furthermore, long-term collected data can form a historical database for analyzing periodic patterns or trend evolution, providing a basis for planning and prevention. Further details are omitted here.

[0038] Drive unit 4, located on fuselage 1, works with airbag 2 to provide power and adjust flight attitude. Drive unit 4, such as an electric motor, propeller, or jet engine, provides active propulsion, enabling rapid changes in flight speed and altitude. Airbag 2 provides passive lift through buoyancy adjustment, such as inflation / deflation control in existing technologies, reducing power consumption. During stable cruise, the buoyancy provided by airbag 2 can share some of the weight, reducing the energy consumption of drive unit 4. During acceleration or change of direction, drive unit 4 responds quickly to provide power. The combination of these two systems achieves high-efficiency power output. The dual-system power architecture provides fault redundancy; if drive unit 4 temporarily fails, airbag 2 can... Maintaining a short-term hover or slow descent prevents loss of control and a crash. If airbag 2 leaks, drive unit 4 can provide emergency lift to maintain flight. Drive unit 4 achieves rapid pitch, roll, and yaw control through vector thrust, such as motor steering or jet direction, with a response time of milliseconds. Airbag 2 achieves smooth attitude fine-tuning through center of gravity shift, such as inflation / deflation position control and airbag deformation, or buoyancy distribution adjustment. At the same time, the flexible structure of airbag 2 can buffer airflow impact and reduce the power overload of drive unit 4 caused by sudden airflow changes. The rapid response of drive unit 4 can counteract the drift of airbag 2 caused by wind. The combination of the two improves wind resistance and stability, which will not be elaborated further here.

[0039] Control unit 5 receives image data and environmental parameters from data acquisition unit 3 and sends control commands to the control mechanism of airbag 2 and drive unit 4. Control unit 5 receives image data from data acquisition unit 3 in real time and performs fusion processing using built-in algorithms, such as computer vision or machine learning models. Image data processing typically includes identifying target objects (e.g., equipment fault points in inspection scenarios), constructing a 3D environmental map (SLAM technology), and dynamically tracking moving objects. Environmental parameter processing typically includes analyzing airflow change trends (predicting turbulence risks), monitoring internal airbag pressure (preventing overcharging / leakage), and sensing the drive unit. Compared to manual interpretation or independent sensor processing, data fusion can improve the accuracy of environmental perception to over 95% for parameters such as operating temperature (overheating warning). Based on the fused multidimensional data, the control unit 5 generates control commands to the control mechanism of the airbag 2 and the drive unit 4 through preset control logic or autonomous learning model. The control unit 5 performs hierarchical and scenario-specific control of the airbag 2 and the drive unit 4 to avoid overload or action conflict of a single actuator. When hovering during aerial photography, the airbag 2 is the main control unit, which adjusts the buoyancy center by inflating and deflating to maintain a horizontal attitude. The drive unit 4 is an auxiliary unit, which triggers compensation power only when a slight deviation is detected, thus reducing energy consumption.

[0040] In this embodiment, the data acquisition unit 3 includes a high-definition camera 301 for acquiring image data of the detection area. The high-definition camera 301 can provide a resolution far exceeding that of ordinary cameras, and can capture subtle features within the detection area, such as the texture of target objects, marking details, and minor environmental changes, significantly improving the accuracy and analytical value of image data. It also supports maintaining image details in complex lighting environments such as strong light, backlight, or low light, avoiding overexposure or underexposure and ensuring the usability of image data in extreme environments. The high-definition camera 301 is equipped with optical image stabilization or electronic image stabilization to reduce image distortion caused by camera body issues. Vibration-induced image blurring ensures the stability of dynamically acquired data. It also adopts industrial-grade protection designs such as dustproof, waterproof and temperature-resistant, which can work continuously in harsh environments, improving the environmental adaptability of the system. It supports automatic adjustment of parameters such as focal length, aperture or shutter speed to adapt to different detection distances and scene requirements. Moreover, the high-definition camera 301 tends to be miniaturized and low-power, which is easy to integrate into the body 1, avoiding the impact of excessive device size or power consumption on the overall performance. Its high reliability and long service life can reduce the frequency of later maintenance and replacement. At the same time, high-quality image data can reduce the hidden costs caused by repetitive work or misjudgment.

[0041] It also includes a protective device 6, which is used to cover or open the high-definition camera 301. During takeoff, landing, or flight, the protective device 6 can reduce the damage to the high-definition camera 301 from external impacts through a buffer structure, such as an elastic material or a shock-absorbing frame, to prevent lens breakage or displacement of internal optical components. This design forms a physical barrier in the covered state, preventing foreign objects such as dust, rainwater, or insects from contacting the lens surface, avoiding image blurring or equipment malfunction due to contamination, and also preventing the lens from being scratched by sharp objects during long-term use, maintaining light transmittance and image clarity. In the covered state, it can maximize the protection of the high-definition camera 301. It automatically opens when image data needs to be acquired to ensure unobstructed imaging. It can be linked with the control unit 5 to automatically switch the protection state according to the equipment status or environmental parameters, reducing manual intervention. By reducing the frequency of lens cleaning and the probability of physical damage, it reduces the workload of daily maintenance, avoids downtime for maintenance due to lens contamination or damage, and improves the continuous operation capability of the system.

[0042] In this embodiment, the protective device 6 can also be controlled to remove fog and foreign objects from the surface of the high-definition camera 301. In environments with high humidity or drastic temperature changes, the protective device 6 can quickly disperse condensation on the surface of the high-definition camera 301 through a built-in heating element or airflow blowing function, avoiding image blurring or detection failure caused by fogging. Unlike the traditional method that relies on manual wiping, the automatic defogging function can be triggered the moment fog is generated, ensuring the continuity of image acquisition. In scenarios such as dust and rain / snow, the protective device 6 can use conventional methods to keep the lens clean, such as a built-in miniature electric brush or a telescopic brush. The scraper removes solid foreign objects such as dust through reciprocating motion, or blows away attached small particles by spraying high-pressure airflow using an air pump; there is no need to retract the body 1 for cleaning, the whole process is automated, reducing labor costs and operational risks, and extending uninterrupted operation time. The cleaning function of the protective device 6 can work in conjunction with the control unit 5 and the data acquisition unit 3 to determine whether defogging is needed through humidity sensors and air pressure sensors, or to detect the degree of lens contamination through image analysis algorithms and automatically start the cleaning program. Pre-cleaning is automatically performed during the take-off and landing phase of the drone, and the cleaning frequency is dynamically adjusted according to the degree of contamination during flight, which will not be elaborated here.

[0043] In this embodiment, the protective device 6 includes a protective shell 601 and a protective cover 602 that can be opened or closed. The high-definition camera 301 is located inside the protective shell 601 and can be manipulated to extend its lens out of the protective shell 601, simultaneously opening the protective cover 602. When the high-definition camera 301 is not in operation, the lens is completely retracted into the protective shell 601, and the protective cover 602 is closed, forming a double-layer protective structure. The protective shell 601 is typically made of high-strength material, which can withstand the effects of impact, vibration, and extreme weather. The inner side of the protective cover 602 can be equipped with a sealing strip. Combined with the waterproof and dustproof design of the protective shell 601, it effectively prevents liquids, dust, or insects from entering the interior, avoiding lens wear or short circuits. The lens assembly is driven to extend out of the protective shell 601 by a motor or pneumatic push rod, simultaneously opening the protective cover 602, like a toothed mechanism. The rack and pinion drive or electromagnetic attraction structure enables rapid response. After the lens is fully extended, the protective cover 602 rotates to the side or is stored in the groove inside the protective shell 601 to ensure that the shooting angle is not obstructed. Under normal circumstances, the lens remains extended and the protective cover 602 remains open to ensure the maximum field of view. In severe weather conditions, the lens can be partially retracted or the extension angle can be adjusted, using the edge of the protective shell 601 as a wind shield to reduce airflow interference to the lens. The lens extension and retraction and the opening and closing of the protective cover 602 adopt an integrated linkage mechanism, which does not require an additional independent drive module, saves installation space, and achieves a compact design. At the same time, the lens extension and retraction process can assist in light cleaning. When retracted, the soft cleaning ring on the inner wall of the protective shell 601 can wipe dust from the lens surface. When extended, the airflow generated by rapid movement can blow away some attached foreign objects, reducing the workload of the automatic cleaning module.

[0044] In this embodiment, the protective shell 601 is installed on the body 1 and its adjustable angle can be achieved using a conventional hinge method. The protective shell 601 is ball-jointed to the body 1, allowing it to rotate freely in both horizontal and vertical directions. This enables the high-definition camera 301 to adjust its viewing angle synchronously. The same device can achieve multi-area rotation of a single camera through angle adjustment, replacing the traditional multi-camera deployment method, saving manufacturing costs, and avoiding multi-lens data synchronization errors. The lens angle is dynamically adjusted according to the environment to avoid obstructions or interference sources. When sunlight shines directly on the lens, the angle of the protective shell 601 can be adjusted to deflect the lens away from the light source, reducing halos and overexposure. During movement, the position of obstacles is fed back in real time by LiDAR or visual sensors, and the lens angle is automatically adjusted to avoid obstructions. The angle adjustment and protective function are linked to improve the device's endurance under harsh conditions, which will not be elaborated further here. During non-working periods, the protective shell 601 can return to a dormant angle, such as vertically downward or close to the body, reducing the exposed area and reducing the wear and tear on the rotating mechanism caused by environmental factors such as wind and rain.

[0045] In this embodiment, the protective cover 602 includes a left cover 6021 and a right cover 6022. The left cover 6021 and right cover 6022 are simultaneously hinged to a torque spring shaft 603. A torque spring 604 is fitted onto the torque spring shaft 603. One end of the torque spring 604 is fixed to the left cover 6021, and the other end is fixed to the right cover 6022. The lens extends out of the protective cover 602. The compression of the torque spring 604 causes the left cover 6021 and right cover 6022 to rotate outward around the torque spring shaft 603. When the high-definition camera 301... When the lens extends from the protective housing 601, the front end of the lens directly pushes the left cover 6021 and right cover 6022 to rotate to both sides. No additional motors or electronic control components are needed; the opening is triggered by the physical displacement of the lens, avoiding opening failures caused by electronic control system malfunctions. The opening process is completed synchronously with the lens extension, resulting in a fast response speed. When the lens retracts from the protective housing 601, the torque spring 604 releases its stored elastic potential energy, driving the left cover 6021 and right cover 6022 to close quickly. The closing process requires no electricity, relying solely on the elastic potential energy of the torque spring 604. To achieve zero-energy protection, the torque spring 604 ensures a tight fit between the left cover 6021 and the right cover 6022, providing excellent sealing. The rotational resistance of the torque spring shaft 603 can be adjusted via spring preload, preventing accidental opening of the protective cover 602 due to minor external impacts. Simultaneously, the symmetrical double-cover structure balances the forces, preventing jamming caused by unilateral force. When closed, the left cover 6021 and right cover 6022 fit snugly against the surface of the protective shell 601 with minimal increase in thickness, saving over 50% of installation space compared to traditional sliding protective covers and avoiding damage caused by... If the protective device 6 is too large, it will affect the aerodynamic layout. During the extension of the lens, if the left cover 6021 and the right cover 6022 are not fully opened, and the opening angle is less than 30°, their edges can still partially block the lens, forming a progressive protection. The elastic coefficient of the torque spring 604 has low temperature sensitivity and can adapt to cold or high temperature environments. It does not require heating or cooling components, which reduces the difficulty of device installation. The core components only include the left cover 6021, the right cover 6022, the torque spring shaft 603, and the torque spring 604. There are no complex electronic control components, which reduces production costs.

[0046] In this embodiment, the data acquisition unit 3 further includes:

[0047] The weather sensor is used to acquire weather parameters of the surrounding environment. It integrates basic sensors such as temperature and humidity, air pressure, light intensity, wind speed and direction, and rainfall to achieve multi-dimensional real-time monitoring. It can also use an electromagnetic shielding shell and digital filtering algorithms to eliminate electromagnetic interference from equipment such as motors and frequency converters in industrial environments, ensuring the stability of weather parameters. It can use conventional preset environmental parameter thresholds to achieve threshold-triggered linkage control, and perform machine learning modeling based on historical data to predict the weather trend for the next 24 hours. It also has features such as early warning of extreme weather and safety protection, which will not be elaborated here.

[0048] The navigation device 7 is used to acquire the position data of the unmanned airship, accurately determining its real-time location. This allows operators to plan suitable flight routes in advance according to mission requirements. During flight, the unmanned airship automatically adjusts its flight attitude and direction by continuously comparing its current position with the preset route, ensuring strict adherence to the predetermined path and improving mission accuracy. If the unmanned airship malfunctions or encounters other emergencies, the position data provided by the navigation device 7 can help operators quickly determine the airship's location, facilitating rescue or recovery efforts, saving search time, increasing the likelihood of retrieval, and preventing greater losses.

[0049] In this embodiment, the drive unit 4 includes four auxiliary lift motors 401 and four tail thrust motors 402. The auxiliary lift motors 401 are located near the bottom end of the body 1, and the tail thrust motors 402 are located at the rear end of the body 1. The auxiliary lift motors 401 are located at each end of the bottom surface of the body 1. They provide additional lift during takeoff, landing, and flight of the unmanned airship. Especially under heavy loads or when encountering turbulent airflow, the auxiliary lift motors 401 help the unmanned airship maintain its altitude better, enhancing its performance. The airship's payload capacity and flight stability are enhanced by this layout, which facilitates precise attitude control. By adjusting the rotational speeds of the four auxiliary lift motors 401, various flight attitudes can be adjusted, improving the airship's maneuverability and controllability, and enabling it to adapt more flexibly to different flight missions and environmental conditions. The tail thrust motor 402, located at the rear of the fuselage 1, provides forward propulsion, allowing the airship to move at high altitudes. This design generates relatively stable thrust, propelling the airship to overcome air resistance and achieve long-distance flight, meeting the navigation requirements of different mission scenarios. The layout of the tail thrust motor 402 helps optimize the airship's aerodynamic performance. Applying thrust to the rear of the airship reduces interference with the overall airflow, lowers air resistance during flight, improves flight efficiency, reduces energy consumption, extends endurance, and helps maintain the airship's straightness and stability. The auxiliary lift motors 401 and tail thrust motor 402 work together to achieve comprehensive control of the airship's flight status, especially during takeoff. The auxiliary lift motor 401 and the tail thrust motor 402 work simultaneously to quickly provide lift and thrust, enabling the unmanned airship to take off rapidly. During flight, the working state of the auxiliary lift motor 401 and the tail thrust motor 402 can be flexibly adjusted according to different flight attitudes and mission requirements to achieve operations such as stable flight, turning, acceleration or deceleration. This collaborative working mode can give full play to the advantages of the auxiliary lift motor 401 and the tail thrust motor 402, optimize the overall flight performance of the unmanned airship, and improve its adaptability and mission execution capabilities in various complex environments.

[0050] The auxiliary lift motor 401 and tail thrust motor 402 can be controlled to start or stop. In the prior art, an electronic speed controller 8 is typically used to control the speed of the auxiliary lift motor 401 and tail thrust motor 402, thereby achieving precise control of the auxiliary lift motor 401 and tail thrust motor 402. Whether during takeoff, landing, or flight, the output power of the auxiliary lift motor 401 and tail thrust motor 402 can be accurately adjusted according to actual needs to achieve optimal flight performance and attitude control. The electronic speed controller 8 has a fast response capability, able to start or stop the motors in a short time according to the instructions of the control system, or quickly switch between different operating states, making it seamless. When faced with emergencies or needing to quickly adjust its flight status, the unmanned airship can react rapidly, improving its maneuverability and emergency response capabilities. It also avoids unnecessary high-power operation of the auxiliary lift motor 401 and tail thrust motor 402, achieving energy-saving effects and improving endurance. Multiple electronic speed controllers 8 are integrated inside the fuselage 1, ensuring good compatibility and collaborative operation with other electronic systems, such as the flight control system and battery management system. They can receive unified instructions from the flight control system, enabling centralized control and management of all motors, improving the reliability and stability of the unmanned airship. At the same time, it facilitates the maintenance and upgrade of the unmanned airship, reducing maintenance costs and difficulties.

[0051] In this embodiment, the airbag 2 is installed on the top of the body 1. Flexible solar panels 9 are laid around the top of the airbag 2. Adhesive is evenly applied to the top surface of the airbag 2, and then the flexible solar panels 9 are pasted one by one onto the top surface of the airbag 2 according to the set arrangement, ensuring that the flexible solar panels 9 are completely attached to the top surface of the airbag 2 without air bubbles or gaps affecting the pasting effect. This pasting method can tightly attach the flexible solar panels 9 to the curved surface of the top of the airbag 2. Compared with the rigid solar panels in the prior art, it is not limited by the irregular shape of the airbag 2, and can maximize the use of the space on the top of the airbag 2 to receive sunlight, improving the solar energy collection efficiency. At the same time, the lighter weight of the flexible solar panels 9 will not bring too much extra burden to the airbag 2 and the body 1, which is conducive to maintaining the overall weight balance of the unmanned airship and ensuring the flight performance of the unmanned airship. During flight, when encountering turbulence and other situations, the flexible solar panels 9 have a certain degree of flexibility and elasticity, which can better withstand impact and vibration, are not easily damaged, and extend their service life.

[0052] It also includes a battery pack 10, which is fixed inside the body 1 and connected to a flexible solar panel 9 for charging. The flexible solar panel 9 has a high photoelectric conversion efficiency and can effectively convert solar energy into electrical energy under different lighting conditions to quickly charge the battery pack 10, ensuring that the battery pack 10 can store enough power in time to meet the power needs of various devices on the unmanned airship. The flexible solar panel 9 can be flexibly laid according to the shape of the top of the airbag 2 to maximize the absorption of sunlight. No matter what flight attitude the unmanned airship is in, it can ensure a good charging effect, improving the flexibility and stability of charging. This charging method reduces the dependence on external charging equipment, reduces the risk of charging failure due to charging equipment failure or charging line damage, improves the reliability of the charging system, ensures continuous power supply to the unmanned airship, and enables it to perform tasks stably for a long time. Further details are omitted here.

[0053] This embodiment also includes a data transmission unit 11, which transmits image data, location data, and environmental parameters of the detection area to the ground control station. The high-definition camera 301 captures image data in real time, allowing operators to observe the surrounding environment of the unmanned airship, including the state of target objects and environmental changes. By transmitting location data and environmental parameters of the detection area, the ground control station can monitor the unmanned airship's precise location, flight trajectory, and speed in real time, helping operators to monitor and track the unmanned airship and ensure it flies along the predetermined route. It also facilitates quick location determination in case of abnormal situations and allows for rescue or other countermeasures. Based on the real-time transmitted image data, operators can assess the unmanned airship's mission performance. For example, during photogrammetry or agricultural patrol missions, they can adjust the shooting angle, flight altitude, or patrol area based on image feedback to obtain more accurate and comprehensive data, improving mission completion quality.

Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
