Description

Technical Field

[0001] The present invention relates to the technical field of unmanned aerial vehicle monitoring, and in particular to an unmanned aerial vehicle intelligent high-cold ecological monitoring device. Background Art

[0002] With the rapid development of drone technology, drones are playing an increasingly important role in various monitoring tasks, especially in the field of ecological environment monitoring. Due to their efficient and flexible flight capabilities, drones have been widely used in monitoring work in a variety of complex environments. Especially in high-altitude cold areas, drones can help collect remote sensing data, ecological environment information, and wildlife dynamics, etc., reducing the workload of manual inspections. However, extreme weather conditions in high-altitude cold areas, such as strong winds, low temperatures, and ice and snow cover, pose huge challenges to the normal flight and data collection of drones.

[0003] Existing drone technology has made some progress in the field of ecological monitoring. Especially in normal temperature environments, the flight stability, monitoring accuracy and endurance of drones can meet the needs of general monitoring tasks. Some high-performance drones already have relatively mature flight control systems, data transmission systems and camera monitoring functions, and can operate in complex terrain or relatively severe weather conditions. However, facing high-altitude cold environments, the functions of traditional drones are still insufficient. Especially in high-altitude cold areas, low temperatures will reduce the battery efficiency of drones, cameras are prone to frost at extremely low temperatures, strong winds may cause drones to fly unsteadily, and ice and snow covering the ground will also affect the safe landing of drones. These problems limit the application of drones in high-altitude cold environments.

[0004] In the existing technology, due to the lack of technical solutions specifically designed for high-cold environments, traditional drones are prone to problems such as insufficient power, unstable flight attitude, and damage to monitoring equipment during flight in high-cold areas. Especially in strong winds, the propellers of drones are easily disturbed by airflow, resulting in unstable flight and affecting the accuracy of monitoring data. Therefore, how to improve the flight stability of drones in high-cold areas, especially by improving the adjustment system of propeller blades to cope with wind speed changes, has become a technical problem that needs to be solved urgently. Summary of the invention

[0005] In view of the shortcomings of the prior art, the present invention provides an unmanned aerial vehicle intelligent high-cold ecological monitoring device, which solves the problem in the prior art of lacking a technical solution specifically designed for high-cold environments.

[0009] The angle of the propeller blade is adjusted by the mutual meshing of bevel gear 1, bevel gear 2, bevel gear 3 and bevel gear 4. Bevel gear 1 is connected to the motor output shaft, and bevel gear 4 transmits power to the propeller blade through a connecting rod. A propeller bearing seat is provided at the triangle of the outer shell, and the propeller blade rotates at the inner ring. The propeller blade is made of carbon fiber material;

[0010] A camera bracket is provided at the bottom of the body, which is connected to the body through a receiving member. The camera is installed on the camera bracket. The angle of the camera is adjusted by a gear shaft, and the gear shaft is locked in the card slot through the cooperation of a plunger and a card block;

[0011] The bottom of the fuselage is connected to a landing support frame by bolts, and a spring is provided on the surface to provide cushioning when the drone lands. The heating plate melts the ice and snow on the ground, and the rubber anti-skid pad prevents sliding.

[0012] Preferably, an integrated box is provided in the body, in which a control circuit board and a battery are installed, and the battery is used to supply power to various electrical systems of the drone.

[0013] Preferably, the propeller blades are connected to the motor via bevel gear one, bevel gear two is meshed with bevel gear one, bevel gear two is connected to the inner ring of the propeller bearing seat via a rotating shaft, bevel gear three is meshed with bevel gear two, and bevel gear four is used to transmit power and adjust the angle of the propeller blades.

[0014] Preferably, the camera is connected to the receiving part and the camera bracket through a threaded column at the bottom of the locking nut, the surface of the tooth shaft is provided with a thread, and a sleeve rod is fixed to one side of the receiving part. The tooth shaft is rotated to drive the plunger to move downward inside the sleeve rod, and the plunger opens the block and inserts it into the slot.

[0015] Preferably, the push column is connected to the camera bracket through a sleeve, and a tooth shaft is provided on the push column. A second spring is provided in the sleeve. When the push column is pressed, the second spring is compressed to push the limit block to slide into the limit groove. A tooth groove is provided inside the contact part between the receiving part and the push column, and the tooth shaft can be engaged in the tooth groove.

[0016] Preferably, the floor support frame is connected to the body via a spring 1 and a rubber anti-skid pad, the spring 1 is used to provide a buffering function, and the heating plate is connected to the drone battery and automatically starts when the drone lands to melt ice and snow on the ground.

[0017] Preferably, a cable channel is provided inside the drone arm, and the cable channel is used to connect the motor of the drone and the control circuit board in the body to ensure the transmission of power and control signals.

[0018] Preferably, the rubber anti-skid pad is designed in a strip shape and is installed at the bottom of the floor support frame.

[0019] Preferably, a solar auxiliary charging panel is provided in the integrated box on the top of the body to provide additional power support for the battery of the drone.

[0020] Working principle: When it is necessary to conduct inspections in high-cold areas, the camera can be placed on the outside of the sleeve in advance. At this time, the threaded column is rotated. Due to the threads on the surface, the threaded column continuously moves downward. At this time, the plunger is trapezoidal. As the threaded column continues to go deeper, the plunger stretches the blocks on both sides and inserts them into the slot, thereby achieving the effect of locking the installation. After installing the camera, press the push column with both hands. Since spring 2 is provided in the sleeve, spring 2 is compressed. At the same time, the tooth shaft on the surface of the push column is no longer limited by the tooth groove inside the receiving part. When the push column is pressed, the limit block inside the sleeve When the limit slot on the edge of the pressing column slides, due to the compression of spring 2, the limit slot is pressed to the point where it is no longer limited by the limit block, the receiving part can be bent to adjust the angle, and when the hand is released and no longer pressed, spring 2 is reset, and the limit slot is snapped back to the limit block, and the gear shaft is snapped in the gear slot for limited placement. Due to strong winds in high-altitude and cold regions, the camera may swing back and forth, causing unstable shooting. It can also improve the efficiency of monitoring. When the drone is not in use, the camera can be adjusted to be parallel and downward to prevent the lens from directly contacting the air surface and frosting when working in high-altitude and cold regions, which affects the monitoring work. During flight, the lens information input by the camera is transmitted back to the integrated box. The integrated box on the top of the fuselage carries battery and chip information, which is used to reserve power for the drone and transmit information to the central control in a timely manner, ensuring the timeliness of the information. The angle of the propeller blades can be adjusted according to the weather problems in the high-cold areas for a period of time. When adjustment is needed, propeller blades are set at the triangular part of the outer shell, and the motor on the lower surface of the top shell drives the bevel gear 1 to rotate. Due to the meshing relationship between the bevel gear 1, bevel gear 2, bevel gear 3 and bevel gear 4, the bevel gears on the three sides rotate. The inner ring of the propeller bearing seat is adjusted to a tilted state with the propeller blades to reduce the interference of airflow when the wind is strong. The motor is used to drive the rotation of the entire outer shell. When landing, the drone arm at the bottom of the side frame is made of hollow rubber material, which can adsorb the ground and provide buffering at the same time. At the same time, the surface of the landing support frame at the bottom of the body is provided with a spring for buffering. Before landing, the heating plate can be controlled to melt the ice and snow on the ground, and a stable landing can be carried out after melting. The rubber anti-skid pad is also an anti-skid strip to prevent the drone from slipping when landing, thereby improving the overall adaptability in high-altitude cold areas.

[0021] The present invention provides a UAV intelligent high-cold ecological monitoring device. It has the following beneficial effects:

[0022] 1. The present invention can flexibly adjust the propeller blade angle according to the real-time wind speed and airflow changes, so as to ensure that the UAV can maintain a stable flight attitude in a high-cold environment with strong winds or unstable airflow. This effectively reduces the impact of wind on the flight stability of the UAV and improves the UAV's wind resistance in adverse weather conditions.

[0023] 2. The camera installation and adjustment system of the present invention can not only quickly install and remove the camera, but also accurately adjust the angle of the camera and lock it through the cooperation of the gear shaft, plunger and block. Even in the case of strong wind in the high-cold environment, the camera can still maintain a stable shooting angle, avoiding the shaking or blurring of the monitoring picture caused by the swing of the camera, thereby improving the quality and reliability of the monitoring data.

[0024] 3. The present invention ensures that the drone can land safely and smoothly on snow-covered ground. The heating plate is activated before landing to quickly melt the ice and snow on the ground to prevent the drone from sliding. The rubber anti-skid pad further enhances the friction of the drone, ensuring that it will not slide or tip over when landing on snow and ice, significantly improving the landing stability of the drone under harsh ground conditions.

[0025] 4. The spring structure installed on the landing support frame of the present invention can provide effective buffering when the drone lands, reducing the impact force during landing. Especially on cold and hard ground, the buffering structure can protect the drone from damage caused by strong impact, thereby extending the service life of the equipment and improving the operational safety of the drone in harsh environments.

[0026] 5. The present invention realizes the real-time transmission of monitoring data through the wireless transmission module in the integrated box. Even in remote and cold areas, the real-time data collected by the camera can still be accurately transmitted to the ground control center. This not only improves the efficiency and accuracy of data collection, but also enables monitoring tasks to be carried out seamlessly under extreme conditions, facilitating subsequent environmental analysis and processing.

DETAILED DESCRIPTION

[0038] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0039] Please refer to the attached Figure 1 -Attached Fig.10 An embodiment of the present invention provides an unmanned aerial vehicle (UAV) intelligent high-cold ecological monitoring device, including: a body, an unmanned aerial vehicle (UAV) arm, a landing gear, propeller blades, a motor, a camera, a heating plate, a rubber anti-slip pad, etc.

[0040] The drone is designed to perform long-term and stable ecological monitoring work in extreme climate conditions, especially in high-cold environments. By combining an adjustable propeller system, a camera angle adjustment system, and a heating and buffering structure, the drone can work normally under conditions of changing wind speeds and extremely low temperatures, and ensure the accuracy of its monitoring data.

[0041] The propeller blades are the main flight control device of the drone and are rotated by the motor. At the end of the drone arm, the propeller blades are fixedly connected to the housing through the propeller bearing seat. The motor is installed under the housing and transmits power through the bevel gear transmission system to achieve the angle adjustment of the blades.

[0042] Specifically, the motor drives bevel gear 1 to rotate bevel gear 2. Bevel gear 2 and bevel gear 3 mesh with each other, and bevel gear 3 is connected to bevel gear 4. Bevel gear 4 transmits power to the propeller blades through a connecting rod. Through this multi-stage transmission structure, precise angle adjustment of the blades can be achieved.

[0043] In high-cold areas, wind speed varies greatly, especially in high-altitude areas, where airflow disturbances may have a significant impact on the stable flight of the drone. The angle adjustment of the propeller blades 9 can be adjusted according to the real-time wind speed conditions. When the wind speed is high, the propeller blades 9 can be adjusted to a tilted state to reduce the interference of the wind on the blades and improve the flight stability of the drone. This design greatly improves the adaptability of the drone in extreme environments and ensures the smooth progress of monitoring tasks.

[0044] The camera is used for real-time monitoring of the alpine ecological environment and is installed on the camera bracket at the bottom of the machine body. The camera can be installed and removed through the receiving parts. The angle adjustment of the camera is achieved through the gear shaft. The surface of the gear shaft is provided with threads. When the gear shaft is rotated, the plunger moves downward in the sleeve rod, and the plunger will push the block to expand and lock into the slot, thereby locking the angle of the camera.

[0045] In addition, the pressing column can release the angle lock of the camera 24 by the linkage with the sleeve through the compression of the spring 2, thereby adjusting the monitoring angle of the camera 24. In a high-cold environment, the direction of the camera 24 can be flexibly adjusted according to monitoring needs to ensure the accuracy of data collection.

[0046] In extremely cold regions, the temperature may be extremely low, and the camera 24 is prone to shaking due to the cold or wind speed, affecting the monitoring effect. The device can effectively reduce the swing of the camera 24 through a unique camera 24 locking and angle adjustment system, ensuring that the camera can shoot stably even in a strong wind environment. At the same time, the system is easy to disassemble and install, and the camera can be quickly replaced or adjusted to meet the monitoring needs in different environments.

[0047] When landing in cold regions, drones often face snow-covered ground, which may cause the drone to slide or even get damaged. To solve this problem, a heating plate and rubber anti-skid pad are installed at the bottom of the drone. The heating plate is powered by the battery in the drone. When the drone is about to land, the battery control system will start the heating plate, which quickly heats the snow and ice on the ground, melting it and creating a safe landing area.

[0048] At the same time, a rubber anti-skid pad is set at the bottom of the landing support frame to increase the friction of the drone when landing and prevent it from sliding. A spring is also set on the support frame to provide additional cushioning during landing, ensuring that the drone can land smoothly and safely.

[0049] This design effectively solves the problem of unstable landing of drones on ice and snow covered ground. By combining the melting of ice and snow with the anti-skid pad 12, the drone can be ensured to land steadily in bad weather conditions, avoiding the tipping or damage of the drone due to sliding. At the same time, the buffering function of the spring 13 can also reduce the impact force during landing and protect the electronic equipment inside the drone from damage. This function greatly improves the applicability of drones in extreme environments, especially when performing long-term monitoring tasks in cold areas.

[0050] The monitoring data captured by the camera will be transmitted to the drone's integrated box in real time through the wireless communication module. The control circuit board in the integrated box is responsible for processing this data and uploading it to the ground control center. A solar auxiliary charging panel is also installed on the top of the fuselage. In the case of sufficient sunlight, the solar charging panel can provide additional power support for the drone's battery and extend the flight time.

[0051] In addition, the battery also provides power for the camera, heating plate and propeller adjustment system, ensuring that the drone can continue to work in high-cold environments. Through reasonable power management and data transmission design, the drone can ensure real-time data and sufficient power in adverse weather conditions.

[0052] The design of the drone takes full account of the energy demand in high-altitude cold regions. High-altitude cold environments usually accelerate the energy consumption of batteries, and the solar-assisted charging panel can provide additional energy during flight, extending the flight time of the drone and reducing the problems caused by insufficient power. At the same time, the data transmission system ensures the real-time monitoring data, and can ensure accurate data transmission even in remote areas, which is convenient for subsequent analysis and processing.

[0053] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
