Description

Technical Field

[0001] This utility model belongs to the field of cloud precipitation particle observation technology in cloud precipitation theory, and specifically relates to an airborne holographic cloud precipitation particle imager. Background Technology

[0002] Most existing cloud precipitation particle imagers are fixedly installed at fixed locations in the area to be measured. Multiple holographic cloud precipitation particle imagers are installed to monitor the points, and the data is then processed by built-in software or a remote computer. The most obvious feature and drawback is that the monitoring points are fixed, the monitoring radius is limited, the acquired 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

[0003] The purpose of this invention is to overcome the shortcomings of existing fixed-position and multi-point monitoring, such as data errors, poor timeliness, and high cost.

[0004] To achieve the above objectives, this utility model provides an airborne holographic cloud precipitation particle imager, which is characterized by including a cylindrical pod, a conical pod cover fixed to the front end of the cylindrical pod, and a strip-shaped ellipsoidal end cover fixed to the rear end of the cylindrical pod.

[0005] A laser module mounting shell and a camera component mounting shell are respectively provided at both ends of the rear side of the strip-shaped ellipsoidal end cap;

[0006] The laser module is coaxially arranged with the laser module mounting housing, and the light emitting end of the laser module faces the first remote end of the laser module mounting housing away from the strip-shaped ellipsoidal end cap. The first remote end is provided with a first reflector cover plate at a 45° angle to the axis of the laser module, so that the emitted light of the laser module is reflected by the first reflector mounted on the first reflector cover plate, passes through the first light hole opened on the inner side of the first remote end, and is perpendicularly projected onto the camera assembly mounting housing;

[0007] The camera assembly and the camera assembly mounting housing are coaxially arranged; the camera assembly includes a camera and a telecentric lens.

[0008] A second reflector cover plate is provided at the second remote end of the camera assembly mounting housing, which is directly opposite the first remote end. The second reflector cover plate is symmetrical to the first reflector cover plate about the cylindrical pod axis.

[0009] A second reflector is installed on the inner side of the second reflector cover to reflect the laser reflected by the first reflector to the telecentric lens and then onto the camera;

[0010] A second light aperture is provided on the inner side of the second distal end, which is directly opposite to the first light aperture;

[0011] An optical transceiver unit is fixed inside the front end of the cylindrical pod.

[0012] 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

[0021] Figure 1 The image shows an airborne holographic cloud precipitation particle imager, comprising a cylindrical pod 1, a conical pod cover 2 fixed to the front end of the cylindrical pod 1, and a strip-shaped ellipsoidal end cover 3 fixed to the rear end of the cylindrical pod 1 (i.e., the surface is spherical and the whole is strip-shaped). The cylindrical pod 1 has excellent airflow guidance function and performance. Together with the conical pod cover 2, it can effectively reduce wind resistance and greatly avoid the breakage of cloud precipitation particles, which helps to improve the accuracy and reliability of particle detection.

[0022] Depend on Figure 1 As can be seen, a laser module mounting shell 4 and a camera component mounting shell 5 are respectively provided at both ends of the rear side of the strip-shaped ellipsoidal end cap 3; combined with Figure 2As can be seen, the laser module 6 and the laser module mounting housing 4 are coaxially arranged, and the light emitting end of the laser module 6 faces the first remote end of the laser module mounting housing 4 away from the strip-shaped ellipsoidal end cap 3. The first remote end is provided with a first reflector cover plate 7 at a 45° angle to the axis of the laser module 6, so that the emitted light from the laser module 6 is reflected by the first reflector 8 installed on the first reflector cover plate 7, passes through the first light hole 9 opened on the inner side of the first remote end, and is perpendicularly projected onto the camera assembly mounting housing 5; a camera assembly coaxial with it is installed in the camera assembly mounting housing 5, and the camera assembly includes a camera 10 and a telecentric lens 11; and the camera assembly mounting housing 5 A second reflector cover 12, at a 45° angle to the axis of the camera assembly, is provided at the second distal end, which is directly opposite the first distal end. This second reflector cover 12 is symmetrical to the first reflector cover 7 about the cylindrical pod 1. A second reflector 13 is installed inside the second reflector cover 12 to reflect the laser light reflected by the first reflector 8 to the telecentric lens 11, which then enters the camera 10, thus completing the detection of water mist particles. A second light aperture 14, directly opposite the first light aperture 9, is provided inside the second distal end. Both the first light aperture 9 and the second light aperture 14 are equipped with protective glass and an electric heating ring, with the electric heating ring located inside the protective glass. The electric heating ring helps to avoid the adverse effects of low temperature, thus ensuring the stability and reliability of the detection.

[0023] To facilitate remote operation and data transmission, this embodiment has two sets of optical transceiver units 15 fixed inside the front end of the cylindrical pod 1, which are symmetrically arranged about the axis of the cylindrical pod 1. Cable fixing blocks 19 are fixed at both the front and rear ends of the optical transceiver units 15 inside the cylindrical pod (1) to facilitate cable fixing and installation. The drive circuit board 15 is fixed inside the front end of the cylindrical pod 1, and the drive circuit board 15 is mounted on a circuit board fixing block 16 located at the center of the rear side of the strip-shaped ellipsoidal end cover 3. A circuit board cover plate 17 is provided at the front end of the circuit board fixing block 16 to enhance the protection of the drive circuit board.

[0024] To ensure the guidance of the entire airborne holographic cloud precipitation particle imager, this embodiment includes an internal guide ring 18 inside the cylindrical pod 1, located at the rear end of the optical transceiver unit 15. Ideally, it should be fixed at the geometric center (center of gravity) of the entire airborne holographic cloud precipitation particle imager to facilitate overall gravity balance and overall hoisting during use. Simultaneously, this embodiment includes a pod fixing ring 20 between the front end of the cylindrical pod 1 and the conical pod cover 2 to achieve a fixed connection between the conical pod cover 2 and the cylindrical pod 1.

[0025] Depend on Figure 1As can be seen, the top surface of the cylindrical pod 1 is provided with a photoelectric hybrid socket 21 and a power socket 22, and the top surface of the cylindrical pod 1 is provided with a first waterproof seat 23 and a second waterproof seat 24. The photoelectric hybrid socket 21 and the power socket 22 are respectively led out from the first waterproof seat 23 and the second waterproof seat 24, and are integrally installed with the cylindrical pod 1 through the first waterproof seat 23 and the second waterproof seat 24, and have a certain height, which effectively prevents liquid from entering the cylindrical pod 1 through the gap at the cable outlet.

[0026] The airborne holographic cloud precipitation particle imager is mounted on a drone or other flight control system. After flying to the area to be measured, it monitors cloud precipitation 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.

[0027] Furthermore, the airborne holographic cloud precipitation particle imager has a simple overall structure, making it easy to use and maintain. In particular, its streamlined shape greatly reduces wind resistance and particle breakage, resulting in high timeliness, accuracy, and reliability.
