Description

The invention relates to shipbuilding, in particular to ship rescue equipment for receiving rescue craft on board a rescue ship.

A technical solution is known (copyright certificate SU No. 1625776 A1, 02/07/1991 [1]), the technical result of which is to increase the safety of delivery of rescue craft aboard a rescue ship in stormy conditions.

The known device ([1]) for receiving aboard life-saving craft includes a slip, a towing winch with a tow rope, and a gripper assembly for the rescue craft connected to the tow rope. The device is equipped with an unmanned aerial vehicle 6 with remote control, a propulsion device and a cargo winch mounted on the hull of the aircraft, as well as an additional towing winch mounted on the hull of the rescue vessel and a remote control unit for the unmanned aerial vehicle. The gripping unit of the rescue craft is made in the form of a mesh jump-shaped mash with a flexible elastic support ring in the lower part, a mesh dome in the upper part and tie rings installed around the perimeter of the elastic support ring on the tie cable. The technical result of the known invention is to increase the safety of the delivery of rescue craft aboard a rescue ship in stormy conditions.

However, the use of the known device ([1]) in a storm is a time-consuming operation due to the fact that it is necessary to ensure reliable positioning of the rescue device relative to the rescue vessel connected to the unmanned aerial vehicle via a cable - hose.

In addition, the hull, controls and propulsion of the unmanned aerial vehicle are connected to the remote control unit via a cable - hose, which significantly reduces the radius of rescue operations.

There is also known a method of remote reconnaissance (application RU No. 2009146819 A, 12/17/2009 [2]) when conducting emergency rescue operations, which consists in obtaining images of the object of work using a controlled video camera installed on a remotely piloted small-sized aircraft in which reconnaissance is carried out on the basis of multichannel radio communications, sequentially shooting inside and outside the object with a digital video camera and a heat finder located coaxially with it, digitally processing the image obtained, clearing the image about vibration, and thermal video overlay layers of the image on the screen of the portable computer, the co-processing of successive images to obtain a panoramic image, the use of sensors and a laser altimeter to exclude the aircraft colliding with the obstacle.

The development of control signals for a remotely piloted small-sized aircraft to interpret the obtained images under adverse weather conditions that adversely affect the production of high-quality images significantly limits the use of the known method and device for its implementation.

The objective of the proposed technical solution is to increase the safety of delivery of rescue craft aboard a rescue ship in stormy conditions.

The problem is solved due to the fact that in the device for receiving rescue equipment on board a rescue vessel, comprising a slip, a towing winch with a tow rope, and a rescue craft gripping unit connected to the tow rope equipped with an unmanned aerial vehicle with remote control, propulsion and a winch mounted on the body of this aircraft, and a remote control unit for an unmanned aerial vehicle, and The capture boat for the rescue craft is made in the form of a mesh net-shaped mash with a flexible elastic support ring in the lower part, a mesh dome in the upper part and with coupling rings installed around the perimeter of the elastic support ring on the coupling cable, while the coupling cable is on the flexible elastic support ring of the mesh-like mesh the mash is connected to the running end of the tow rope of the towing winch, and the dome of the net net-shaped mash is connected via the freight cable to the cargo winch of an unmanned aerial vehicle this with the remote control unit for an unmanned aerial vehicle, and the remote control unit for an unmanned aerial vehicle is connected to the control elements of an unmanned aerial vehicle by a radio channel and is made in the form of an automatic control system for the movement of an unmanned aerial vehicle in terms of roll, pitch, speed, heading and altitude, wherein the remote control unit for an unmanned aerial vehicle contains a complex of satellite radio navigation system such as GPS or GLONASS, dstvom which generate control signals for unmanned aircraft, taking into account environmental hydrometeorological situation in the area of rescue operations and the current motion parameters of a drone.

The essence of the proposed technical solution is illustrated by the drawing.

A device for receiving aboard a rescue vessel 1 rescue craft 2 comprises a slip 3 made at the aft end of the ship’s hull 1, a towing winch 4 with a tow rope 5, and a rescue craft gripper assembly connected to the tow rope 5. The device is equipped with an unmanned aerial vehicle 6 s remote control, propulsion 7 and a cargo winch 8 mounted on the body of the aircraft 6, the remote control unit 9 of the unmanned aerial vehicle 6. Capture unit rescue floating Food 2 is made in the form of a mesh net-shaped mash 10 with a flexible elastic support ring 11 in the lower part, a mesh dome 12 in the upper part and coupling rings 13 mounted around the perimeter of the elastic support ring 11 on the coupling cable 14.

The dome 12 of the net-shaped net-shaped mash is connected by means of a cargo cable 15 to a cargo winch 8 of an unmanned aerial vehicle 6, the hull of the latter, its mover 7 and controls are connected via a radio channel 16 to a remote control unit 9 of an unmanned aerial vehicle 6, and a coupling cable 14 on a flexible elastic support the ring 11 of the mesh net-shaped mash 10 is connected with the running end of the tow rope 5 of the towing winch 4.

The radio communication between the rescue vessel 1 and the unmanned aerial vehicle 6 is carried out by means of an ANLI A-100MU radio antenna 16 and an INTEGRA TR radio modem, which are installed on the unmanned aerial vehicle 6.

The ship module consists of a multiplexing and data synchronization module, as well as a personal computer.

The automatic control system for the movement of an unmanned aerial vehicle includes a central microcontroller module, which, according to a given program, controls an electric drive that ensures the movement of an unmanned aerial vehicle 6, taking into account the current speed, heading, roll and pitch angles, and flight altitude. The Atmel AVRMega 128 microcontroller, an MMC or SD flash memory slot, a real-time clock chip, two RS-232 ports, an Analog Device AD7718 ADC chip, an analog multiplexer chip for sharing one port are located on the microcontroller board of type chip45 SAVVY 128 RS-232 different measuring sensors of the current motion parameters of the unmanned aerial vehicle 6, propulsion controller 7 type IR3320S and voltage converters. Analog channels are digitized using a single 16-bit ADC. From the ship computer of the rescue vessel 1, the work program of the unmanned aerial vehicle 6 is entered and the received data is viewed and processed. The central microcontroller module transmits data using an SBE-44 type inductive modem to a similar ship's inductive modem. Inductive modems are used to transmit current telemetric information, which is used to generate control signals for the unmanned aerial vehicle 6, taking into account the surrounding hydrometeorological situation in the area of rescue operations and the current motion parameters of the unmanned aerial vehicle 6.

The positioning of the unmanned aerial vehicle 6 relative to the rescue vessel 1 and the location of the rescue vehicle 2 is carried out by the ship complex satellite radio-navigation system such as GPS or GLONASS.

Unmanned aerial vehicle 6 can be performed with vertical take-off and landing.

A device for receiving aboard rescue vessels of rescue craft from an abandoned crew of ships is operated with sequential execution of the following operations.

An unmanned aerial vehicle 6 rises from the tugboat - a rescue vessel 1, is controlled by radio channel 16, is brought to a hovering position above the watercraft 2 of the net-shaped landing gear 10, suspended from the unmanned aerial vehicle 6. Then the net-shaped net-shaped squash 10 is lowered onto the ship 2, so that its supporting the ring 11 has reached the depth of immersion of the watercraft 2. The support ring 11 of the mesh net-shaped mash is tightened, after which the towing cable 5 is selected and the slipway 3 is dragged along the slip 3 to the rescue vehicle udno 1.
