Definitions

• the present invention relates to a floating periscope, in particular for an underwater vehicle.
• Floating periscopes particularly for underwater vehicles of this type, which comprise a floating container having an elongate shape, one end of which is adapted to protrude above the level of the vessel, are already known in the state of the art.
• a stabilized platform itself carried by cardan suspension means.
• cardan suspension means Such a system is known for example from US 7,279,675.
• floating periscopes can be used as a replacement for or in addition to the periscopes of the massif of these, which need to be hoisted above the surface of the water and from the submarine, while this is periscopic immersion and at reduced speed.
• floating periscopes Compared to these periscopes hoisted from the submarine, floating periscopes have a number of advantages, insofar as submarine immersion is of little importance and where a floating periscope does not leave visible trail. However, in these floating periscopes as illustrated by the previous document, there is the problem of the stability of the shooting means.
• stabilization means of the shooting means may for example be gyroscopic stabilization means associated with the support platform of the shooting means, or else computer stabilization means by processing the images delivered by these shooting means.
• stabilization means may for example be gyroscopic stabilization means associated with the support platform of the shooting means, or else computer stabilization means by processing the images delivered by these shooting means.
• these different means are relatively complex and expensive to implement.
• the object of the invention is therefore to solve these problems.
• the subject of the invention is a floating periscope, in particular for underwater vehicles, of the type comprising a floating container having an elongate shape, one end of which is adapted to protrude above the water level and comprises means of shooting the environment, carried by a stabilized platform itself carried by cardan suspension means, characterized in that the stabilized platform is associated with at least one stabilizing rod extending according to the longitudinal axis of the container and one end of which is associated with the platform and the other end of which is associated with stabilizing weight means in position.
• the floating periscope comprises one or more of the following characteristics: the end of the container adapted to protrude above the level of the water and comprising the means for shooting of the environment, has a transparent porthole,
• the stabilization platform is articulated in a frame around a first axis, and this frame is articulated on the rest of the container around a second axis perpendicular to the first,
• the container is cylindrical
• the shooting means comprise means forming cameras
• the information transmission means are wire means
• the underwater vehicle is a submarine proper
• the underwater vehicle is a submarine drone
• FIG. 1 illustrates the principle of using a floating periscope according to the invention
• FIG. 2 represents a side view of such a periscope
• FIG. 3 represents a perspective view of the internal structure of such a periscope
• - Figure 4 shows a top view of this structure
• - Figure 5 shows a sectional view of such a structure.
• a floating periscope such as that designated by the general reference 1 in these figures, can be deployed for example from an underwater vehicle designated by the general reference 2 in Figure 1, this machine submarine being for example a submarine proper.
• a floating periscope may for example be used to complete or replace the use of a sub-massif periscope such as the periscope designated by the general reference 3 in FIG. 1, and then allows the environment of the submarine to be observed. this, and detect for example surface vessels, such as the building designated by the general reference 4 in this Figure 1.
• the periscope according to the invention comprises a floating container designated by the general reference 5 in this figure, this floating container having an elongated shape, one end of which is adapted to project above the water level and comprises means 6 for taking the environment, carried by a platform stabilized itself supported by cardan suspension means.
• the shooting means 6 are for example formed by camera means and are arranged under a transparent dome 7 of the corresponding end of the container 5.
• This container may for example be connected by information transmission means such as for example wired means to the underwater vehicle.
• the means 6 for shooting the environment are carried by a stabilized platform designated by the general reference 8 in these figures, associated with at least one stabilizing rod designated by the general reference 9, extending along the longitudinal axis of the container 5, the latter being for example cylindrical, and one end of which is associated with the platform and whose other end is associated with means for forming a stabilization weight in position, designated by the general reference 10.
• the stabilization platform 8 is articulated in a frame 11 along a first axis AA, this frame 1 1 itself being hinged to the rest of the container around a second axis BB perpendicular to the first .
• the platform and the frame are articulated with respect to each other, and with respect to the remainder of the periscope structure via hinge pin portions, one of which is for example designated by the general reference 12 in Figure 4.
• a floating periscope can be used from an underwater vehicle that can be in the form of a subset. marine proper, a submarine drone or underwater equipment provided for example by divers who can thus remain discreet in the context mentioned in the preamble of this description.
• the container may also be equipped with means of accelerating its speed of recovery to the surface after its release, to cause it to jump over the surface of the water and especially above the waves , and thus to improve the observation of the environment.
• mechanical, pyrotechnic, hydraulic or pneumatic means may be associated with the container to accelerate its ascent rate.
• the processed images can then be processed in real time or in deferred time.
• the means of shooting can be formed by means of different types, cameras, cameras, IR, etc ...
• the floating periscope As soon as the floating periscope is released, it is able to deliver information concerning the environment during its displacement under, at and above the surface of the water.
• cardan suspension means associated with the rod and the flyweight makes it possible to greatly limit the phenomenon of instability of the images obtained, and the result obtained can be improved by means of digital image processing, such as that is known.
• digital image processing such as that is known.
• other embodiments may be envisaged.
