Abstract

The utility model discloses a stable platform of a night-vision device for vessels, comprising two stable loops, a platform, a wind-force balance plate, and a weight block. The utility model is characterized in that: two loops are horizontally arranged, the position of a shaft is mutually perpendicular, the shaft of an inner loop is arranged on a bracket, another set of shafts of the inner loop is placed in an outer loop. The wind-force balance plate and the weight block are equipped at the surrounding positions of the outer loop, and the components, such as an inspection component, an illumination component, are pressed on the outer loop. As the wind effect of the upper and the lower parts of the outer loop is counteracted, the image is steady under the gravity of the weight block and two loops when the vessel body swings in the wind and waves. As the utility model does not adopt the expensive gyroscopic and electric steady platform, the utility model has low cost of manufacture and can be used for common night-vision devices.

Description

Night vision device stable platform peculiar to vessel

Technical field:

The utility model relates to a kind of night vision device stable platform peculiar to vessel

Background technology:

Present commercially available night vision device peculiar to vessel, passive type and active two kinds are arranged, the former is as thermal imaging system, low-light or lighting level pick up camera, the latter goes to shine target with infrared searchlight or visible light search lamp, with noctovisor or B, object is photographed, on read-out, show again then.

Above-mentioned two kinds of schemes all are proven technique.But a common shortcoming is arranged, be that price is expensive, can not adopt for general ship, reason is that ship is constantly shaking, image also will rock, manufacturer adopts the gyro of high speed revolution for this reason, utilizes its inertia, makes stable platform, though but effect is good, and cost an arm and a leg (needing hundreds of thousands of unit/platform), example is the sea lion 3R visible light gyrostabilized platform peculiar to vessel that other shore company produces, and also has in addition to adopt the calculating electronic solution to solve, for example Nanjing is liked to propose religion and is broadcast reportedly that the technology Co., Ltd produces, but also need tens thousand of unit/platforms, so stable platform is too expensive, has restricted user's purchase.For reducing the cost, the manufacturer that has is simply without stable platform, allows the image Free Slosh, can see target exactly.

Summary of the invention:

The utility model night vision device stable platform peculiar to vessel mainly is to have solved the expensive problem of stable platform, makes that it is simple in structure, firm, low cost, " stablizing " be obvious.

For achieving the above object, the utility model night vision device stable platform peculiar to vessel, mainly realize by following structure: promptly make the annulus of two horizontal positioned, (but also other shapes are now encircled, but that the fastness and the radius of gyration are annulus is best, minimum).

90 ° of their shaft position phase mutual deviations, be subjected to the influence of wind-force for counteracting finder itself, fix the wind power balance plate of (or with The Cloud Terrace rotation) in their other directions, downside at ring has also added saddle weight in addition, whole finder center of gravity is fallen, and above-mentioned is exactly formation i.e. two stabilizing rings, platform, saddle weight and wind power balance plates of stable platform.

The utility model compared with prior art has following distinguishing feature and good effect:

1, whole night vision device cost peculiar to vessel is declined to a great extent, reason is that wherein stable platform drops to hundreds of unit from hundreds of thousands of unit, several ten thousand yuan; 2, make camera coverage open; 3, simple in structure, easy to maintenance, sturdy and durable.

Below in conjunction with accompanying drawing and embodiment, the utility model is done further thin the description.

Accompanying drawing 1, for the utility model in conjunction with other devices after the integral structure block diagram.

Accompanying drawing 2 is the block diagram of another kind of embodiment.

The specific embodiment:

As shown in Figure 1, the utility model is made of two annulus 5 and 6 platforms 4 (comprising connecting rod), wind power balance plate 7, saddle weight 8.Pick up camera 1 is fixed on the The Cloud Terrace 3 with search lamp 2, and The Cloud Terrace 3 is fixed on the platform 4, and platform 4 is fixed on the outer shroud 5, and outer shroud 5 is penetrated by one group of axle of interior ring 6, and another group axle of interior ring 6 penetrates support 9.Fixing the wind power balance plate 7 of (or rotating with The Cloud Terrace 3) around below outer shroud 5, it fixing some saddle weights 8 bottom.Such structure is because the suffered wind-force of finder self basic neutralisation, so under the moment loading of the surplus gravity of saddle weight 8, overcome the friction moment that stabilizing ring 5,6 is equipped with spool, and made the member substantially maintenance level of outer shroud more than 5 motionless.

As shown in Figure 2, pick up camera 1, search lamp 2 are fixed on the The Cloud Terrace 3, and The Cloud Terrace 3 is fixed on the platform 4, are fixed with a saddle weight 8 below the platform 4, have 4 pull bars to link to each other with interior ring 6 on it, are provided with wind power balance plate 7 all around.The axle that the axle of interior ring 6 penetrates outer shroud 5, outer shroud 5 penetrates support 9.Like this under the gravitational moment effect of saddle weight 8 and The Cloud Terrace 3, overcome stabilizing ring 5 with 6 and 5 with support 9 countershafts on friction moment, and make interior each member maintenance level of encircling more than 6 motionless.

Above-mentioned two figure can upright setting aboard ship; The 180 ° of handstand of also can reversing are provided with aboard ship, and (for example on mast), but this moment, saddle weight 8 all should be cancelled.

The utility model is suitable for the stable platform of making various night vision devices peculiar to vessel.
