Description

Technical Field

[0001] The utility model belongs to the field of electronic information equipment design, and specifically relates to a light-thunder integrated reconnaissance device. Background Art

[0002] At present, in the field of electronic information, integrated optical and radar equipment is needed. The radar can achieve 360° rotation in azimuth, the optoelectronics can achieve 360° rotation in azimuth, and the pitch can achieve ±30° rotation. The weight of the equipment is limited to 20 kg to meet the carrying requirements of a single soldier. The usual design mode is that the radar and optoelectronic structure are designed independently, and then installed as a whole through transitional structural parts. At the same time, the main drive control components of the radar servo mechanism and the optoelectronic servo mechanism, including motors, encoders, and slip rings, are usually independent components, and many structural parts need to be designed and installed as one. This results in a bloated overall structural link, uncontrollable weight, and inability to achieve portability requirements.

[0003] Due to the large amount of data processing in radar equipment, the heating problem is more prominent. Most of them use air cooling with high cost performance to achieve thermal balance of the equipment. However, the air cooling design needs to inhale cold air from the atmosphere and discharge hot air into the atmosphere after completing the heat exchange. Therefore, it is impossible to achieve perfect performance. In salt fog or sand and dust environment, the reliability of the equipment cannot be guaranteed, the equipment life is shortened, and even serious consequences may occur. Utility Model Content

[0037] A light-mine integrated reconnaissance device, see Figure 1 , including an optoelectronic servo assembly 1, a radar servo assembly 2, a radar sensor unit 3, and an optoelectronic device 4. The optoelectronic servo assembly 1 and the radar servo assembly 2 do not rotate about their main axes in azimuth.

[0038] Among them, the photoelectric servo component 1 refers to Figure 2 and Figure 3, including a base 101, an optoelectronic servo housing 102, an optoelectronic azimuth drive assembly device 103, an optical mine azimuth axis adapter 104, a mounting bracket 105, an optoelectronic pitch drive assembly device 106, and a pitch C-ring axis 107.

[0039] See also Figure 4 The photoelectric azimuth drive assembly 103 uses a first torque motor 1031, a first encoder 1032, a first slip ring 1033, a photoelectric azimuth assembly main shaft 1034 and a photoelectric azimuth assembly housing 1035, which can simultaneously realize the rotation, position signal detection, and static-dynamic signal transmission functions of the photoelectric servo component 1. During operation, the photoelectric azimuth assembly main shaft 1034 does not rotate, but the photoelectric azimuth assembly housing 1035 rotates. The base 101 and the light mine azimuth axis adapter 104 are integrally installed with the photoelectric azimuth assembly main shaft 1034 and do not rotate. The photoelectric servo housing 102, the mounting bracket 105, the photoelectric pitch drive assembly 106, and the pitch C-ring shaft 107 are integrally installed with the photoelectric azimuth assembly housing 1035, and rotate together around the photoelectric azimuth assembly main shaft 1034.

The optoelectronic pitch assembly device housing 1063 is installed as a whole with the mounting bracket 105. The rotating spindle drives the optoelectronic device 4 through the pitch C ring shaft 107 to realize the pitch dimension rotation.

[0041] See also Figure 6 The radar servo assembly 2 includes a radar azimuth drive assembly device 201, a radar servo housing 202, a light mine installation adapter 203 and a transition installation 204.

[0042] The optoelectronic azimuth drive assembly device 103, the optoelectronic pitch drive assembly device 106 and the radar azimuth drive assembly device 201 simultaneously have the functions of a torque motor, an encoder and a slip ring, which greatly reduces the number of installation links, improves the installation accuracy and reduces the weight of the system.

[0045] The first heat absorber 3043 is located between the TR assembly 303 and the antenna unit 302, and the first heat sink 3041 passes through the left side of the chassis 301 and is exposed to the air. The first heat absorber 3043 absorbs the heat generated by the TR assembly 303, and the first heat pipe 3042 quickly conducts the heat to the first heat sink 3041, and the heat quickly diffuses into the atmosphere to achieve natural heat dissipation.
