Abstract

The utility model discloses a night vision device for boats with a wind shield and capability of measuring distance, which is mainly characterized in terms of technology that a metal windproof upper shield is fixed on a bracket of a boat out of a night vision vidicon, and a half ball shaped transparent cover glass is fixed under the bracket by bolts, thus, the natural wind or the opposite wind produced during sailing of the boat is completely cut off from the self blow of the vidicon. The utility model is applicable to boats, in particular to boats sailing on the sea.

Description

Be provided with the night vision device peculiar to vessel that hurricane globe can be found range

Technical field

The utility model relates to a kind of physical construction of night vision device peculiar to vessel, especially relates to a kind of night vision device peculiar to vessel that hurricane globe can be found range that is provided with.

Background technology

At present commercially available night vision device peculiar to vessel seldom, very expensive, most 1,000,000 yuan/more than the platform, for example Huazhong Photoelectric Technology Inst. smart machine of YQZ series of products, other shore, Beijing company, Kawasaki, Japan, the Canada that produce add the product of creating group etc. and all are.

Because ship navigates by water in stormy waves, night vision camera confidential upper and lower with ship, about shake, and the blowing of apparent wind that produces himself also will be subjected to the navigation of natural wind or ship time the and swinging is so be dual influence.For head it off, above-mentioned each product all adopts expensive gyrostabilized platform, or the computing machine stable platform, and self can not measure the distance of target, need employ the radar conjunction measuring (precision is high certainly) on the ship.

For solve wave and wind-force directly to the problem that influences of viewer self, I had applied for two patents in last year, application number is respectively: 200520116479.1 and 200520117451.X, elaborate two stabilizing rings of what use is made of and measures such as ballast and wind power balance plate on it and solved stable problem, but in the actual detected, discovery wind power balance plate can not be offset the influence that wind-force blows viewer self fully, make image produce the additional swing of all directions frequently, also can't utilize target on The Cloud Terrace, to calculate the distance of target in the angle of depression of gained certainly.

Summary of the invention

The utility model mainly is with solving the apparent wind that produces when marine natural wind advances with ship to the blowing of night vision camera machine self, make its influence that is not subjected to this wind-force fully, also can reaching simultaneously and measure and the display-object approximate distance.

In order to achieve the above object, the utility model is mainly realized by following structure; Promptly below the fixing night vision device support of hull (or above), at viewer and The Cloud Terrace, the outside of parts such as stabilising arrangement, not with the hurricane globe that or two are made of metal cap and clear glass hemisphere (or greater than, less than hemisphere) or cylindrical enclosure that installs additional that contacts, wind can not be blown on the interior member of cover fully, under the effect of the stabilising arrangement of viewer in cover, just can not swing, like this so can utilize the angle of depression of target to calculate distance.The utility model compared with prior art has following distinguishing feature and effect:

1, makes viewer self not be subjected to the influence of natural wind and relative wind-force fully, in cover under the stabilising arrangement effect, reach the shown image that comes out except that the translation of upper and lower some rhythm, do not have any swing (that fearness gyrostabilized platform of translation problem also exists).

2, the night vision device peculiar to vessel that constitutes like this, because of not additional swing, so can utilize target can demonstrate the target approximate distance by calculating after meter is handled at the angle of depression on the The Cloud Terrace, simultaneously also may be to utilize on the The Cloud Terrace from the bow angle that turns round of starboard left, obtain the ship side angle of target, also can get orientation (orientation=course ± ship side angle).

Annotate: (d is to target range to utilize calculating formula d=hctg α certainly, h is the setting height(from bottom) of this sight device apart from the water surface, α is the angle of depression that obtains on the The Cloud Terrace) calculate target apart from the time, it is general because the α angle is too little, and near ctg α rate of change zero degree is very big, make the distance error that records can be bigger, but we can utilize the precision that manufactures that improves The Cloud Terrace, increase the setting height(from bottom) (for example be located at mast on) of viewer apart from the water surface, reduce the friction factor of stablizing on the annulate shaft, measure meticulously, in advance on each distance with radar contrast measures such as correction to reduce range error be fully possible.It is calculated that: for example the target actual range is 500 meters, and angular error is 0.1 degree, adorns high h=15 rice.The distance error that then records is about 30 meters; 1.3 meters of 100 meters time errors of distance, thus error and little, and the near more distance that records of target is also accurate more, and this also conforms with the requirement that boat is protected fully.If also can be used daytime, only need a visible light camera to be installed side by side and get final product on former night vision camera machine side.

The utility model is applicable to ship, particularly sea going ship.

Below in conjunction with accompanying drawing and embodiment the utility model is described in further detail.

Description of drawings

Fig. 1 is the whole cut-away view of the night vision device of the utility model after in conjunction with miscellaneous part.

Fig. 2 is another embodiment stereographic map of the utility model.

Embodiment

As shown in Figure 1, a metal hurricane globe 2 is being fixed in the below of support 6 of the present utility model, it links to each other with the translucent cover 1 of a semisphere by screw down, the hurricane globe of forming a sealing, the bearing bracket stand 5 that useful bolt 13 and support 6 fix in the cover, one group of axle of ring 4 is worn thereon in stable, penetrates outer shroud 3 after another group axle horizontal becomes 90 degree, and outer shroud is fixed with saddle weight 7, The Cloud Terrace 8, night vision camera machine 9 for 3 times successively.Except that interior ring 4, other are not all with sallying.(or upper and lower mobile average waterline is in this position) just can be by the angle of depression on the The Cloud Terrace 8 on the central horizontal line of the visual field time for the waterline (with the water osculatory) of observing target when video camera 9, by the COMPUTER CALCULATION in control and orientation, the range display 12 and on panel, demonstrate the range-azimuth of target, on display screen 11, demonstrate image.

As shown in Figure 2, be another embodiment, its difference from Example 1 is that the windproof shroud 14 of metal is located at the outside of support 6, continuing to use screw on it links to each other with a cylindrical glass cover 1, the upper edge of cloche 1 is fixed a windproof cover 2 of going up of metal again, the common hurricane globe of forming sealing, the order that assembly in the cover connects makes progress successively, promptly earlier the axle of stable outer shroud 3 is interted into bearing bracket stand 5, the axle horizontal of ring 4 penetrates outer shroud 3 after becoming 90 degree in stable, fixing saddle weight 7 above it successively, The Cloud Terrace 8, night vision camera machine 9.Except that outer shroud 3, remaining assembly is not all with sallying.So can record target direction, distance and image by the method for legend 1 equally.

The electric current of all electricity consumption devices all is connected by lead 10 with marking current.

The utility model is applicable to ship, particularly sea going ship.
