[0002] Existing airborne holographic cloud particle measuring instruments are mostly fixedly installed at fixed locations in the area to be measured. Multiple airborne holographic cloud particle measuring instruments are installed to monitor the points, and the data is finally processed by built-in software or a remote computer. The most obvious feature, and also the drawback, is that the monitoring points are fixed, the monitoring radius is limited, the monitoring data is discontinuous, and the final data obtained is biased because it is only calculated by balancing multiple points. In particular, the real-time performance is poor, which leads to a significant difference between the obtained results and the actual situation, resulting in inaccurate weather forecasts. There is also the problem of high cost for multiple installations and monitoring. Utility Model Content

The main control unit includes a cylindrical pod, a conical pod rear cover fixed to the rear end of the cylindrical pod, and a spherical front cover fixed to the front end of the cylindrical pod.

[0005] The rear end of the cylindrical pod is equipped with an optical transceiver unit and a main control circuit board.

[0006] The particle monitoring and acquisition unit includes a strip-shaped ellipsoidal shell, which is suspended from the front end of the cylindrical pod by a transition link.

[0007] The advantages of this utility model are: simple structure, convenient use and maintenance, especially the streamlined overall shape, which greatly reduces wind resistance and particle breakage, and has high timeliness, accuracy and reliability. Attached Figure Description

[0018] Figure 1The image shows an airborne holographic cloud particle measuring instrument, including a main control unit and a particle monitoring and acquisition unit. In order to enhance the guidance of the atmosphere, especially to avoid the occurrence of particle breakage, this embodiment adopts a streamlined design for the whole machine. This is mainly reflected in the main control unit, which includes a cylindrical pod 1, a conical pod rear cover 2 fixed to the rear end of the cylindrical pod 1, and a spherical front cover 3 fixed to the front end of the cylindrical pod 1. The shape of all components is mainly based on cylindrical and spherical design elements, which is conducive to the realization of the streamlined shape of the whole machine. The cylindrical pod 1 is equipped with an optical transceiver unit 4 and a main control circuit board 5 at its rear end, enabling the processing and remote transmission of collected data. The particle monitoring and acquisition unit includes a streamlined ellipsoidal shell 6, which resembles a flat body with an arc-shaped surface. This ellipsoidal shell 6 is suspended from the front end of the cylindrical pod 1 by a transition link 7. In this way, the whole machine is roughly divided into upper and lower layers, simulating a small aircraft. Each layer does not affect the others, yet they are connected as a whole, ensuring the stability of their respective airflows while also completing functions such as mutual cooperation, data guidance, and remote transmission.

[0019] Depend on Figure 1 Clearly visible, the front ends of the strip-shaped ellipsoidal shell 6 are fixedly connected to a first support arm 8 and a second support arm 9 arranged in parallel, providing a support structure for the relatively horizontal and parallel laser and camera, thus improving the reliability and stability of data acquisition; wherein, a first support arm 8 and a second support arm 9 are fixedly connected to their respective inner sidewalls. Figure 2 The first protective cover 10 and the second protective cover 11 are shown. More precisely, a camera 13 is installed inside a first support arm 8, and a first reflector cover 14 is installed at the front end of the first support arm 8. A first reflector 15 is installed inside the first reflector cover 14 at a 45° angle to the optical axis of the camera 13. A lens 16 is fixed inside the first protective cover 10 (a lens of a certain magnification can be installed as needed to improve clarity and detail). The optical axis of the lens 16 is parallel to the incident light of the first reflector 15, that is, the image of the lens 16 is projected after the first reflector 15 and reflected into the camera 13 to complete the capture.

[0020] The second protective cover 11 houses a laser 17, which emits laser light that is incident on the lens 16 and reflected by the first reflector 15 before entering the camera 13. This design ensures that the laser light is incident perpendicularly on the lens 16, maximizing the clarity and accuracy of particle imaging and avoiding stray light interference.

[0021] The entrances of the first protective cover 10 and the second protective cover 11 are each equipped with a protective glass and an electric heating ring, with the electric heating ring located inside the protective glass.

[0022] The drive circuit board 18 is fixed inside the strip-shaped ellipsoidal housing 6 and is connected to the camera 13, laser 17, optical transceiver unit 4 and main control circuit board 5 respectively. The electrical connection with the optical transceiver unit and the main control circuit board is mainly completed through the cable laid in the transition link 7.

[0023] Inside the cylindrical pod 1, a guide ring 19 is provided on the rear side of the optical transceiver unit 4. This facilitates the centering of the internal circuit boards or components, ensures the centered design of the internal structure, and makes the overall center of gravity stable and balanced, thus achieving overall stability.

[0024] The cylindrical pod 1 has an inner fixing ring 20 located at the rear end of the conical pod rear cover 2, which facilitates the fixed installation of the conical pod rear cover 2.

[0025] For ease of connection, the transition link 7 provided in this embodiment is clamped to the front end of the cylindrical pod 1 by a clamping sleeve 21. The clamping sleeve 21 can be connected by an upper and lower mating method, that is, it is composed of an upper clamping sleeve and a lower clamping sleeve. The upper clamping sleeve is mainly fastened to the cylindrical pod, while the lower clamping sleeve is mainly fixedly connected to the top end of the transition link 7. After completion, the upper clamping sleeve and the lower clamping sleeve can be fixedly connected by mating buckles or screws to form a clamp.

[0026] Depend on Figure 3 As can be seen, cable fixing blocks 22 are fixed at both the front and rear ends of the optical transceiver unit 4 inside the cylindrical pod 1.

[0027] Depend on Figure 4 As can be seen, a photoelectric hybrid socket 23 and a power socket 24 are provided on the top surface of the cylindrical pod 1. The cables connected to them are connected to the optical transceiver unit 4 and the main control circuit board 5 through the cable fixing block 22 to complete the establishment and transmission of power and channels.

[0028] See you later Figure 1 A first waterproof seat 25 and a second waterproof seat 26 are provided on the top surface of the cylindrical pod 1. A photoelectric hybrid socket 23 and a power socket 24 are respectively led out from the first waterproof seat 25 and the second waterproof seat 26. With the help of the first waterproof seat 25 and the second waterproof seat 26 which are higher than the top surface of the cylindrical pod 1, water vapor or liquid can be effectively prevented from entering the cylindrical pod 1, achieving a good hydrophobic and waterproof effect.

[0029] The airborne holographic cloud particle measuring instrument is mounted on a manned aircraft or other flight control system. After flying to the area to be measured, it monitors cloud droplet particles and stores the data. Then, the data is copied to a dedicated computer and specialized software is used to calculate the number, concentration, and size of particles in the sampled airspace.

[0030] The airborne holographic cloud particle measuring instrument has a simple overall structure, is easy to use and maintain, and its streamlined shape greatly reduces wind resistance and particle breakage, resulting in high accuracy and reliability.
