The invention relates to a device for detection over a large area of sunken objects and precise aiming lifting mechanism on the sunken submarine object (snag) in conditions of limited visibility, even its total absence, and can be used for floating in the works to find snags, and topscoring or dredging.

The number of known devices designed to capture and move the timber, characteristics which are reflected in copyright certificates and patents under№1594057, 1549898, 1553510, 1643409, 1616852, 1636298, 1615751, 1557071, 1650560, 1581678 [1-11]. The nature of these inventions is that they have in their construction, the drive mechanism of the jaws of the grapple, two pairs of teeth, rotating around a fixed axis, fixed to the housing of the device, and are designed to capture and move timber.

The disadvantages of existing designs is the narrow range of their responsibilities, limited capture of timber blind and their subsequent move. The operation of these mechanisms is characterized by the difficulty and sometimes impossibility of their use in conditions of limited visibility or no, and complete unsuitability for the detection of interest statement items even on a small at the Alenia them from design (the function “blind search”).

For lifting snag CRI rafting has designed a special grapple, which is well into the ground and retrieves silty drift wood. The design of this grapple described in the literature [12]. The disadvantages of this material should also include a narrow range of operations and the complexity of their implementation directly under and grab some from him removing, in an environment with limited visibility or no.

The technical result to be solved by the applicant, is expanding operations lifting device, and provide ease of working with it, enabling work on the detection and recovery of sunken objects lifting device over a large area in conditions of limited visibility and no.

The technical result is achieved by a device for detection and precise aiming lifting mechanism on sunken wood, including grapple, sonar sensor, the block signal processing, display and communication between them, according to the invention, the sonar sensor is installed directly on the end side of the jaw lifting mechanism, not in contact with the raised sinkers, with the possibility of the spread of the signal in the form of a cone with the vertex in the sensor and souped the processes with open jaws in the direction of the workspace lifting mechanism, and with closed jaws directed toward the bottom of the water body under non-normal angle and allowing the operator to determine the presence of sunk away from the lifting mechanism and to perform a precise alignment of the grapple to snag the image formed on the display echo sounder as a result of processing the reflected signal.

The proposed device is illustrated by drawings, where figure 1 - front view with open jaws; Fig 2. - front view with half-open jaws; Fig 3 is a front view with closed jaws.

Device for precise targeting lifting mechanism includes a sonar sensor 1, which is mounted directly on the jaw lifting of the gripper mechanism 2 and through the wire 3 is connected to the block signal processing (microcomputers) 4 and liquid crystal display 5, located in the operator's cab controls lifting mechanism.

The device operates as follows. In the examination mode of bottom of water body (search snags) the statement includes a sounder 1 and with closed jaws, the lifting mechanism 2 rotates around the vertical axis, for example, by means of the rotator. Sonar sensor 1 generates ultrasonic waves (signals), the incidence of which has the shape of a cone with the vertex in the sensor and sent to the site is on the water body, located in side, at some distance from the lifting mechanism 2. The signal is reflected from solid objects and surfaces in its path in the water column or on the bottom and back, is perceived by the sonar sensor 1. Returning to the sensor signal is converted into an electrical pulse and supplied to the processing unit 4, and then the display sonar 5. Thus, on the display 5, which is in the field of view of the operator, an image solid objects and surfaces that are at some distance from the grapple. Focusing on this image, the operator can determine the location, configuration, and dimensions discovered the sunken object.

In the capture mode of the detected object, the device operates as follows. After the discovery of the sunken object, the operator shall grab at him, opens the jaw lifting mechanism 2 so that the fixed jaw sonar sensor 1 is constantly kept right item in-band signal. At that moment, when the bandwidth of the signal is directed vertically down onto the captured object, the jaws of the grapple will be fully open (the signal has the shape of a cone with the vertex in the sensor and coincides in direction with the workspace lifting mechanism 2). Therefore clicks the zoom, on the display 5, which is in the field of view of the operator, an image solid objects and surfaces in the working area of the lifting mechanism. Focusing on this image, the operator produces a precise alignment of the lifting mechanism on the objective to capture it and rise to the surface.
