Abstract

FIELD: transport.

SUBSTANCE: invention relates to diving, particularly, to diver underwater carriers. Proposed torpedo-shaped carrier is composed of two pod drives of left and right sides. Said pod drives are retracted into light case opening in turning about vertical axis. Pod drives are arranged in symmetry about carrier lengthwise axis to hinge from stern to bow. Left side pod drive is engaged with left side turning mechanism while right side pod drive is coupled with right side turning mechanism. Turning mechanisms (cylinders) are coupled via reduction gearboxes with their drive motors. Drive motors are arranged at top and bottom openings of carrier light case.

EFFECT: decreased sizes.

Description

The invention relates to the field of diving equipment, and in particular to means of transport for divers under water - transporters (carriers and towing) of divers.

Numerous designs of domestic and foreign carriers of divers are known, which provide divers with movement and cargo delivery under water. This is a native carrier of Triton-2 divers (AS USSR No. 91080 dated 11/03/1975), as well as torpedo-shaped carriers used from TA Siren-UM type AS (AS USSR No. 106966 from 12/16/1976).

All known carriers of divers (AS USSR No. 91080, 106966, 123043, 123763, 162877, 224317, 317434 - analogues of the invention) are miniature submarines having a sturdy and lightweight hull with general ship signage and trim systems, diving and surfacing , crew cabin, as well as a battery power plant, propulsion and steering complex, instrument compartment and control panel.

As a prototype of the invention, we will choose the domestic four-seater transporter (group tow) of divers "Grape", the description of which is given in the book by V.P. Troshin, P.V. Troshin "From the diver to the ichthionaut", Ed. St. Petersburg, SPbGMTU, 2004, p. 283-286.

The diver’s transporter has a torpedo-shaped hull in which (from bow to stern): engine-steering complex (DRC), made in the form of two helm columns (left and right), retractable into a niche of the light hull when turning around the vertical axis 90 °, instrument compartment with remote control, battery, cargo container. Divers lie on the carrier on top. The carrier’s DRC is tucked into the niche of the lightweight casing if the product is transported in a shipping container.

One of the disadvantages of the prototype is that it is retractable in a niche of the lightweight housing of the DRC and takes up a lot of space in length, since its WRCs are located on opposite sides of a single rotary mechanism. This reduces the technical characteristics of the transporter, as its permissible length is limited. You have to sacrifice either the volume of the cargo container or the volume of the battery.

The objective of the present invention is to provide a transporter of divers having a length of less than the prototype of the DRC light inside the prototype, with equal power and other equal thrust capabilities, noise efficiency, and controllability in the vertical and horizontal planes.

The problem was solved by creating a DRC that can be retracted into a niche of a light hull and made with two swivel mechanisms for left and right sides, located side by side on the left and right sides, while both throttle columns are piled from the stern in the bow and placed symmetrically next to the left and right from the longitudinal axis of the diver transporter. At the same time, the right-hand side of the sideboard is connected with the starboard rotary mechanism, the left side of the sideboard is connected with the left side rotary mechanism. These rotary mechanisms through gearboxes are connected with their drive motors installed in the upper and lower niches of the light body of the conveyor.

The design of the DRC transporter of the divers is presented in figure 1 and figure 2.

Figure 1 shows the DRC in the folded state (VRK removed).

Figure 2 shows the DRC in working condition (WRC disclosed).

DRC, located between the bow differential equalizing tank 1 and the instrument compartment of the transporter 2, contains: two WRC left and right sides 3; two brushless submersible propeller motors 4; swivel mechanism (cylinder) of the left-handed steering axle (heading control) 5; swivel mechanism (cylinder) of the right-handed steering axle (heading control) 6; rotary cylinder drive electric motor of the right VRK 7 with gear; rotary cylinder drive electric motor of the left VRK 8 with gear; an electric motor for turning the left-hand side with a gearbox (depth control) 9, located in the rotary cylinder of the left-hand side; 5; the rotation motor of the right-hand side with a gearbox (depth control) 10, located in the swivel cylinder of the right-hand side 6.

Used by the DRC as follows.

In the transport position, both VRK are littered with a niche in the light body (Fig. 1). After removing the transporter from the transport container, the driver diver turns on the electric motors 7 and 8 and deploys the left and right side steering axes 90 °, bringing them into working position (Fig. 2). In this case, the electric motors 7 and 8 rotate in different directions. To do this, special switches must be provided on the conveyor control panel. The same switches are used to reverse the movement of the air defense system from the working position to the transport one.

Then control according to the conveyor’s course is carried out using a single handle of the drive of electric motors 7 and 8. The electric motors begin to rotate synchronously when the handle is deflected to the left (turn left) or right (turn right).

Depth control is carried out by the same single handle when it is deflected forward (immersion) and backward (ascent). In this case, the motors 9 and 10 are synchronously switched on.

The proposed DRC can be controlled from the transporter’s control panel by the driver-diver in both manual and automatic modes (using the automatic control system).

The production of the declared DRC of the diver’s transporter can be organized at the FSUE Zavod Dvigatel (St. Petersburg).
