Specific embodiment two:

[0040] Reference Figures 1-8 The unmanned aerial vehicle cloud height measuring device mainly comprises an unmanned aerial vehicle main body 1 and a measuring bin 4, and the unmanned aerial vehicle main body 1 serves as a flight carrier and is responsible for carrying the measuring bin 4 to reach a target airspace for cloud height measurement operation; the clamping frame 2 welded on the bottom of the unmanned aerial vehicle main body 1 is matched with the clamping block 3 welded on the top of the measuring bin 4; the installation position of the measuring bin 4 is preliminarily positioned through sliding connection, and then fastened by bolts to ensure the stability of the measuring bin 4 during flight, so as to avoid loosening or displacement caused by factors such as vibration and air flow impact.

[0041] The barrier strip 5 is installed on the front of the measuring chamber 4 and is made of soft material such as rubber or silicone. Its main function is to block dust from entering the measuring chamber 4 during the flight of the unmanned aerial vehicle, preventing dust accumulation from damaging the precision electronic devices inside the chamber and affecting the measurement accuracy and equipment life.

[0042] The auxiliary camera 6 is located at the bottom of the measuring chamber 4 and can capture image information of the ground below the unmanned aerial vehicle. On the one hand, the images captured by the auxiliary camera 6 can provide visual reference for the landing of the unmanned aerial vehicle, assisting the pilot or the automatic driving system to accurately control the landing of the unmanned aerial vehicle; on the other hand, these image data can be correlated and analyzed with cloud height measurement data, such as combining with the ground terrain features to judge the trend of the height change of the cloud layer relative to the ground, assisting meteorological researchers to understand the particularity of the local meteorological environment.

[0043] The partition plate 9 is arranged at the bottom of the front of the measuring chamber 4 and serves as a limiting structure to ensure that the power supply 7 moves along the predetermined track inside the measuring chamber 4, preventing the power supply 7 from sliding out.

[0044] The drive motor 10 is installed in the middle of the front of the partition plate 9 and is the power source for the movement of the power supply 7. After receiving the control command from the unmanned aerial vehicle flight control system or the ground, the drive motor 10 starts to drive the power supply 7 to slide back and forth inside the measuring chamber 4 through the transmission device. The selected motor type should have the characteristics of small size, large torque and fast response speed, such as brushless DC motor, which can not only meet the installation requirements in limited space, but also quickly and accurately execute the movement command.

[0045] The power supply 7 and the measuring chamber 4 are connected by sliding. When it is necessary to switch the distance measuring instrument or perform equipment maintenance, the ground control personnel sends a command to drive the motor 10 to operate, which indirectly drives the power supply 7 to move back and forth along the guide rail inside the measuring chamber 4. When it moves to the front of the measuring chamber 4, due to the inclined design of the inclined strut 11 on the top of the power supply 7, the mounting disc 12 and the sleeve 13 on it will open the barrier strip 5 and protrude out of the measuring chamber 4, so that the distance measuring instrument can detect the external environment without obstacles.

[0046] The inclined strut 11 is made of lightweight high-strength material such as aluminum alloy or carbon fiber composite material, which can withstand a certain weight without adding too much load to the unmanned aerial vehicle. Its inclination angle is carefully designed to ensure that the barrier strip 5 can be smoothly opened when the power supply 7 moves, and to ensure that the sleeve 13 on the mounting disc 12 is in the right measuring position after it protrudes out of the measuring chamber 4, facilitating accurate pointing to the cloud layer. The mounting disc 12, as a transitional structure for carrying the sleeve 13, needs to have good stability, and the connection parts between it and the inclined strut 11 and the sleeve 13 are reinforced to prevent loosening during flight and measurement.

[0047] The wireless receiving controller 14 is installed on one side of the top of the set 13, and it is the information interaction hub of the entire measuring device and the ground control. Equipped with a high-performance antenna, it can stably receive the instructions sent by the ground control station, including selecting to use the millimeter wave radar range finder 21 or the laser range finder 23, starting or stopping the ranging operation, adjusting the measurement parameters, etc. At the same time, it can also feedback the working state information of the measuring device (such as battery power, instrument working temperature, measurement data transmission state, etc.) to the ground, so that the operator can master the equipment operation in real time.

[0048] The drive motor 15 is located in the middle of the top end of the set 13, and it is responsible for driving the chuck 16 to rotate, and then driving the rotating drum 17 to rotate. The drive motor 15 selects a high-precision servo motor, which has precise angle control capability, and can quickly and accurately rotate the required ranging instrument to the front measurement position according to the instructions from the wireless receiving controller 14. For example, when the cloud layer is thick and the weather conditions are complex, preliminary detection needs to be performed through the cloud and fog, and the drive motor 15 rotates the millimeter wave radar range finder 21 to the front; and when the weather is fine and high-precision cloud height data is needed, the laser range finder 23 is rotated to the front.

[0049] The chuck 16 is made of a metal material with a certain elasticity, such as stainless steel, which is tightly clamped with the bottom end of the rotating drum 17, which can not only ensure the stability of the rotating drum 17 during rotation, but also facilitate the disassembly of the rotating drum 17 during equipment maintenance. The rotating drum 17, as the core component of carrying two ranging instruments, has a good balance in its own structure, and will not produce excessive vibration during high-speed rotation, which will affect the measurement accuracy. Its material is selected from lightweight materials with certain electromagnetic shielding performance, such as aluminum alloy coated with nickel, which can not only reduce weight, but also reduce the influence of external electromagnetic interference on the ranging instrument.

[0050] Millimeter wave radar range finder 21 and laser range finder 23: The millimeter wave radar range finder 21 uses the electromagnetic wave characteristics of the millimeter wave frequency band to emit millimeter wave pulses and receive signals reflected by the cloud layer, and calculates the approximate distance range of the cloud layer through signal processing algorithms. It has good penetration in bad weather conditions such as cloud and rain, and can quickly obtain the contour information of the cloud layer. The laser range finder 23 uses high-frequency laser pulses (such as 905nm wavelength) as the detection means, and when the laser pulse meets the cloud bottom and reflects back, the cloud bottom height is accurately calculated according to the propagation speed and round-trip time of the light, and the measurement accuracy can reach centimeter level, which is suitable for high-precision measurement in fine weather. The bottom of the two ranging instruments is provided with a charging interface 24, so that the power can be supplemented in time when needed.

[0051] The rotating groove 19 is opened in the bottom of the sleeve 13, and the rotating ring 25 is located at the bottom of the rotating drum 17 and is matched with the rotating groove 19. They jointly provide stable support for the rotation of the rotating drum 17, ensure the smooth rotation of the rotating drum 17 under the driving of the driving motor 15, reduce the vibration and noise generated by rotation friction, and improve the reliability of the range measuring instrument switching and the stability of the measurement.

[0052] The telescopic power connection pipe 18 is installed on the front surface of the bottom of the sleeve 13, and has a telescopic function, which can freely adjust the length within a certain range. When it is necessary to power the range measuring instrument close to the front surface, the micro cylinder 26 is started, the embedded block 27 is pushed up, the embedded block 27 is clamped with the sleeve frame 22, so as to fix the position of the charging connector 20, the telescopic power connection pipe 18 is stretched, the charging connector 20 is connected with the charging interface 24 at the bottom of the range measuring instrument, and power transmission is realized. The power supply 7 supplies power to the overall assembly in the measuring bin 4. The charging line is installed in the inclined support rod 11 between the power supply 7 and the mounting disc 12. The two micro cylinders 26 indirectly drive the charging connector 20 to ascend and descend. When ascending, the charging connector 20 is inserted into the charging interface 24. When descending, the charging connector 20 is pulled out of the charging interface 24.

[0053] In summary:

[0054] 1. In the device, the unmanned aerial vehicle cloud height measuring device is mainly composed of an unmanned aerial vehicle body 1 and a measuring bin 4 to form an organic whole. The unmanned aerial vehicle body 1 serves as a flight carrier and is responsible for carrying the measuring bin 4 to the target airspace for cloud height measurement operation. The clamping frames 2 welded on the bottom of the unmanned aerial vehicle body 1 are matched with the clamping blocks 3 welded on the top of the measuring bin 4. The installation position of the measuring bin 4 is preliminarily positioned through sliding connection, and then fastened by bolts to ensure the stability of the measuring bin 4 during flight, avoiding loosening or displacement caused by factors such as vibration and airflow impact.

[0055] 2, the power supply 7 and the inside of the measuring bin 4 are slidably connected. When it is necessary to switch the distance measuring instrument or to maintain the equipment, the ground control personnel sends a command to drive the motor 10 to operate, which indirectly drives the power supply 7 to move back and forth along the guide rail inside the measuring bin 4. When moving to the front of the measuring bin 4, due to the inclined design of the top inclined strut 11 of the power supply 7, the mounting disc 12 installed at the top end of the inclined strut 11 and the sleeve 13 thereon will prop open the blocking strip 5 and protrude out of the measuring bin 4, so that the distance measuring instrument can detect the external environment without obstacles. The millimeter wave radar range finder 21 utilizes the electromagnetic wave characteristics of the millimeter wave frequency band to emit millimeter wave pulses and receive signals reflected back by the cloud layer, and calculates the approximate distance range of the cloud layer through a signal processing algorithm. It has good penetration in bad weather conditions such as clouds, rain, etc., and can quickly obtain the contour information of the cloud layer. The laser range finder 23 uses high-frequency laser pulses (such as 905nm wavelength) as a detection means. When the laser pulse meets the cloud bottom and reflects back, the cloud bottom height is accurately calculated according to the propagation speed and round-trip time of light, and the measurement accuracy can reach centimeter level, which is suitable for high-precision measurement in sunny weather. The bottom of the two distance measuring instruments is provided with a charging interface 24, so as to supplement the power in time when necessary.
