Description

Technical Field

[0001] The utility model relates to the field of laser warning, in particular to a quick-detachable laser warning device. Background Art

[0002] Laser warning technology is an important part of modern optoelectronic countermeasures. As a special-purpose reconnaissance method, it is generally fixed on aircraft, armored vehicles or important facilities to measure laser distance and detect, identify and warn signals in real time so that countermeasures can be taken.

[0003] At present, in order to have a full range of detection fields and sufficient bandwidth (detection signal range), most laser warning devices are of integrated design, which is large in size, heavy in weight, and has high power consumption; the working environment of the equipment is generally complex and changeable, and it is easy to suffer accidental damage during operation. The integrated design is extremely inconvenient for maintenance. For miniaturized laser warning equipment, in order to prevent signal detection from being blocked, the installation location is usually limited to the top of the facility, which has certain limitations. Therefore, for laser warning equipment that requires small size, light weight, and easy maintenance, especially in a relatively complex working environment, there are some shortcomings in such laser warning equipment on the market: First, the horizontal field of view angle of the common detection unit module is 30°, and at least 12 detection unit modules must be arranged at the same time to meet the full coverage of the detection field of view, and the overall volume is large; second, there are many internal modules, which are too scattered, the wiring is complex, the assembly is cumbersome, and the reliability is poor; third, in order to avoid signal shielding, the installation location is usually arranged on the top of the equipment, which has great limitations.

[0014] In order to make the purpose, technical scheme and advantages of the embodiments of the present application clearer, the technical scheme in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. The components of the embodiments of the present application described and shown in the drawings here can be arranged and designed in various different configurations. Therefore, the detailed description of the embodiments of the present application provided below in conjunction with the drawings is not intended to limit the scope of protection of the application claimed for protection, but merely represents the selected embodiments of the present application. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without making creative work belong to the scope of protection of the present application. The utility model is further described below in conjunction with the drawings.

[0015] like Figure 1As shown, the utility model specifically relates to a quick-detachable laser warning device, which is light in weight (about 2 kg), small in size (length * width * height: 166 * 145 * 130 mm), and highly integrated; it includes a plurality of detection unit modules 1, a side plate 2, a base 3, a back plate 4, a cover plate 5, a PCBA board 6, and a blower fan 7;

[0016] Among them, the blower fan 7 and the PCBA board 6 are arranged on the base 3, and the PCBA board 6 is arranged above the blower fan 7, the back plate 4 is arranged on one side of the base 3, and a side plate 2 is respectively arranged at both ends of the back plate 4, and is limited by a positioning pin, and a plurality of detection unit modules 1 are arranged between the two side plates 2, the detection unit module 1 and the side plate 2 are fixed to the base 3 by screws, and the cover plate 5 is fixed above the detection unit module 1 and the side plate 2 by screws.

[0017] Furthermore, if Figure 2 As shown, the detection unit module 1 includes a window seat 12, an aperture 11 is arranged on the window seat 12, a sealing ring 10 is arranged on the outer ring of the aperture 11, a shading sheet 9 is arranged above the aperture 11, a window pressing ring 8 is arranged above the shading sheet 9, the window pressing ring 8 is fixed to the window seat 12 by screws, and a detection unit 13 is fixed on the back of the window seat 12.
