Description

The invention relates to floating equipment, mainly to small submarines.

The known floating means containing the hull, periscope, diesel, devices for regulating buoyancy and stability, for example, submarines (according to [1], p. 283; according to [2] type M, p. 219, etc.).

Their disadvantage is that with a fairly slow course at the periscope depth and hovering without a stroke, they do not have sufficient stability. Therefore, the periscope is used on the fly, which unmasks the submarine, since behind the periscope they leave a noticeable mark on the surface of the water ..

Known floating means containing a hull, rudder, periscope, engine, propulsion device, engine operation at periscope depth, regulation of buoyancy, stability and landing, for example, the submarine "Baby" type M [2], s.219 - prototype.

The disadvantage is that the use of a watchdog as invisible to violators, for example for fish conservation, is ineffective because of the wake behind the periscope.

The technical result is the immovable hovering of a floating vehicle at a periscope depth and a rather slow course at that depth without a noticeable trace behind the periscope.

The essence of the invention is that a floating means comprising a body, rudder, propulsion device, periscope, engine, devices for operating the engine at a periscopic depth, regulation of buoyancy, stability and landing, in accordance with the invention also comprises a suspended ballast at the end of the rope with the possibility of deepening the floating means winch, its course and motionless hovering at depth with residual positive buoyancy.

Due to the combination of such signs, a visible space is observed from an imperceptible floating means, patrolling at the periscope depth slowly enough so that there is no noticeable trace behind the periscope, or they hang motionless at this depth. When intruders are discovered, they pop up, give the ship a full turn, overtake and delay the intruders.

A floating facility (hereinafter referred to as a craft) is arranged, for example, as follows.

The drawing shows a boat, side view. The level of the water surface when the watercraft is submerged to the periscope depth and the position of the rope with flexible solid ballast in the position of the stationary vehicle hovering at the periscope depth is shown by a dotted line. Legend:

1 - the hull of the craft with a transparent superstructure-cabin (hereinafter hull),

2 - steering wheel

3 - propulsor, for example a screw with a rotary cylindrical nozzle (hereinafter screw),

4 - periscope with a device for operating the engine at a periscope depth (hereinafter RPG),

5 - winch,

6 - rope

7 - suspended ballast attached to the end of the rope, for example, in the form of a ball (hereinafter the anchor).

The housing 1 is equipped with a steering wheel 2, a screw 3, an RPG 4. A winch 5 is located in the permeable compartment of the housing along the line of buoyancy force (buoyancy force), at the end of the rope 6 of which is anchored 7. Inside the housing 1 there is an engine with an effective silencer and known, for example, according to the book "Elementary theory of a submarine" [3] devices for regulating buoyancy, stability, landing, necessary for a small submarine, as well as a place for 2 ... 4 crew members.

Work, for example, on fish protection from violators, is performed as follows. They arrive at the protected area by the surface position of the craft, stop it, give anchor 7 to the ground, put the craft into position with a residual positive buoyancy of 0.001 ... 0.002 underwater displacement, deepen the craft with winch 5 to the periscope depth, freeze motionless “in secret”, and shut off the engine and shut off the engine conduct observation through the periscope.

For slow patrolling, the engine is started, the boat is given the appropriate stroke, the rope is lengthened at the same time, which is positioned at an angle to the horizon so that the vertical component of the rope tension forces balance the residual positive buoyancy of the craft at the desired depth of immersion and continue observation through the periscope.

When an intruder is found, they come closer to it, drain the ballast tanks, float to the surface, select anchor 7 with a winch 5, overtake and detain the intruder.

So, with the described watercraft they can hang motionlessly at the periscope depth and go on it without a noticeable trace behind the periscope, thereby increasing the effectiveness of the guard.
