Demagnetizing stand with ring operating winding installed in coastal basing on the bench hard pole, while floating base between floating working modules. Device for measuring characteristics of the magnetic field of the object is the original and current data for processing. Post control is designed to control current in the operating winding of the signals of the measuring device. The object is pulled by a winch with a cable through the working coil. Control device with reference points and theodolite identify deviations to the longitudinal axis of the object from passing between remote hard supports the Central yaw axis, and when the floating base and the deviation of the longitudinal axis of the working modules from the left and right directional axes. Authorities testing deviations of the longitudinal axes of the object and working modules are designed as equipped with floating blocks of thrusters in the front and rear parts of the object and working modules. Control post is connected by radio with the control and propulsion devices. The system has RA is P> The invention relates to techniques demagnetization floating objects, in particular ships. Can be used for demagnetization of objects of transport machine-building turbines, diesel engines and other equipment.

Technical means of demagnetization of ferromagnetic floating objects is powered from an external source multiturn operating winding in the form of a solenoid, rings or frames, etc. that are placed in the building where you enter rozmagnesowanie object (1, 2, 3).

An important problem for such a technical solution is the exception error processing resulting from deviations rosmaridiphenol object from the directional axis passing through the center of the working winding. The most acute this problem occurs in the system, representing the working winding in the form of a ring mounted rigidly on the ground (onshore based) or on floating tool (floating base) with sensors measuring the magnetic field along its circumference, where the floating object when processing is pulled through the ring.

The ideal is a drawing of a floating object on the Central yaw axis passing through the center of the working winding, Thu the whole of its length, moving then the object fixed on her cart, strictly along the directional axis. The length of the drawing object is several lengths. However, the cost of building the embankment almost exceed the cost of the ring of the working winding and power supply.

There is an opportunity to provide, refusing promenade, drawing the processed floating object through the ring by means attached to the object pull rope associated with installed on rigid support at the beginning and end of the course the axis of the winch drum. However, there is a need to eliminate the offset of the longitudinal axis of the ferromagnetic mass of the object from the vehicle axis system for hoods cable, wind, waves, tide, etc.

To provide an exception offset to the longitudinal axis of the ferromagnetic mass of the object from the vehicle axis system installed on the floating tool, which itself under the influence of these causes may also be displaced, is even more difficult technical challenge.

Existing stabilization system hold at a given, the floating rate (or flying) object in the form of autopilot from the gyrocompass (or autopilot), etc. provide this process the AI object, when the speed of the haul-off minor (m/h), i.e., the high-speed stream flow is practically absent, the system may not be applicable.

The invention aims creatures systems demagnetization of ferromagnetic objects in the on-shore or floating hosting, free from the above disadvantages.

The problem is solved in that the demagnetization floating ferromagnetic object containing the operating winding in the form of a ring; a source of current supply winding; control; rigid supports, remote from the working winding on the Central yaw axis on both sides at a distance of a few lengths of the object; the rope associated with those on the corresponding rigid support winch and drum and attached to the object to pull it through the ring of the working winding

at the coastal base (when the operating winding with sensors measuring the magnetic fields of the object placed on a rigid support, and the power source and control post on the shore) it is entered:

control device for detecting the deviation of the longitudinal axis of the object from the Central yaw axis when drawing, made in the form of frames, to establish the; the nose and aft of the processed object, and a theodolite mounted in the center of the rigid support behind the subject;

- the bodies of testing deviations of the longitudinal axis of the object from the Central exchange rate of the axis in the form of thrusters in the composition of floating blocks that are installed in the fore and aft parts of the object, and a control station located on the Bank of providing according to theodolite, via a radio channel to enable or disable the thrusters and the return of the object on the Central directional axis;

when a floating base (when the operating winding is placed between the right and left working modules, connected via mechanisms pullups with individual floating anchors, and the power source and control post posted on floating adjacent to one of the working modules, unit) it is entered:

- in addition to the control device of the Central yaw axis of the object mentioned above, the control device for detecting the deviation of the longitudinal axis of the working modules, load-bearing, the working coil from the respective left and right directional axes parallel to the Central yaw axis, is made in the form of reference points set p is itow, set left and right on a rigid support behind the subject;

- the bodies of testing variations, the longitudinal axis of the right and left floating operating modules, supporting the working winding, made in the form of thrusters placed in the nose and aft of the working modules and control station in energomodule providing data theodolites through the channel enable and disable the appropriate thrusters and return floating working modules to exchange the left and right axis and, thus, the operating winding on the Central directional axis.

In Fig. 1 presents the system demagnetization of the ferromagnetic object at the coastal base of Fig.2 - when a floating base.

In Fig. 1 shows: rozmagnesowanie ferromagnetic object 1; thruster in the nose of the object 2 n, in the stern of the object 2 to; deleted rigid supports in front of the object 3.1, behind the object 3.2; traction device with hoist 4.1 (support 3.1. ), a traction rope 4.2 and drum 4.3 (on a support 3.2.), ring operating winding 5, and oriented along the Central yaw axis reference points 6 C (center support 3.1.), 7 C (the centre of the working windings 5), 8 C (in the nose of the object), 9 C (aft) and theodolite 10 C (in the centre of the new axes floating working modules benchmarks 6 l and 6 R (on the left and right ends of the support 3.1.), theodolites 10 l and 10 R (on the left and right ends of the support 3.2. ), power module 11, floating working module 12 l and 12 R (left and right operating winding 5) and oriented on the left and right directional axes of the frames 13 l 14 l 13 R 14 l (in the nose and aft of the left and right working modules 12 l and 12 R), thrusters working modules 15 LF and 15 male, 15 mo and 15 PC (in the fore and aft, left and right working modules 12 l and 12 R).

In Fig. 3 shows thruster (2 h, 2 K), which is a pipe 16 has mounted therein a propeller screw 17 and the drive screw 18, as part of the floating block. The rotation of the propeller provides corresponding movement of the floating block.

Position 19 in Fig.1, 2 marked post control, which together power supply (without specifying positions) in the shore-based system is installed on the shore, and the system floating-launched - in energomodule 11.

The frames 6 C, 7 C, 8 C, 9 C, and theodolite 10 C in the system of both species based shall constitute the control device to detect deviations of the longitudinal axis of the object from the Central exchange. Reference points: 6 l and 6 p 13 l 13 n 14 l and 14 p, and theodolites 10 l and 10 s at a floating base system is avago and right working modules 12 l and 12 R of the left and right directional axes.

The signal measurement information from all control devices are transmitted by radio to control 19.

In the shore-based system (Fig.1) operating winding 5 is placed on a hard bench support (on the ground).

In the system of floating base (Fig.2) operating winding 5 is placed between the left and right floating working modules 12 l and 12 p, connected via mechanisms pullups (spires) with individual floating anchors (no item) that provides the withholding system on the ground. The floating system-based power module 11 and the working module 12 l and 12 p can be installed in a working position (shown in Fig.2), and in transport. In the transport position working units 12 and 13 are adjacent to each other, forming a single craft, and power module, on the upper deck which fits the working winding 5, acts as a tug.

Floating blocks of thrusters (Fig.3) are installed in the bow and stern of the object to be processed so that the pipe axis 16 of the propeller 17 was oriented perpendicular to the longitudinal axis of the object. Propeller device 17 is controlled by radio signals from the position 19 on the shore.

The proposed system works as follows.

The object 1 to be processed, traction rope 4.2 through winch 4.1 installed on the hard support 3.1, extends through the annular working coil 5 mounted in the vertical plane firmly on the ground, powered from an external power source on the shore (out of position). The magnetic state of the object is estimated by measuring the magnetic field measurement, available on the circumference of the ring operating winding 5.

Feed object 1 is held by a rope unwinding from the drum 4.3 installed on a rigid support 3.2.

In normal conditions the longitudinal axis of the ferromagnetic mass of the object 1, taking into account the level of the water surface passes through the center of the ring operating winding 5 and further along the main course of the axis system. However, because of the extrusion of the cable 4.2, and under the influence of wind, waves or tides is the deviation (offset) of the longitudinal axis of the object 1 from the Central yaw axis, causing a measurement error of the magnetic field of the object and its processing. This deviation is recorded by the control device referee floating home, the deviation of the longitudinal axes working units 12 l and 12 R of the left and right directional axes, arising under the influence of the same phenomena are captured by the control device with frames 6 l 13 l 14 l 6 p 13 p 14 p and theodolites 10 l and 10 p.

Signals from the control device are transmitted over the radio channel control station 19, where the angles of deflection of the longitudinal axes of the object 1 and 12 l and 12 p are analyzed in magnitude and sign, and then generated command signals to enable and disable the respective thrusters 2 n and 2 to 15 IO and 15 C, 15 NP and 15 KP, in particular their actuators 18.

Under the influence of thrusters course of the object 1 or the situation of workers of the modules 12 l and 12 p, bearing the working winding, are aligned to match their longitudinal axis with a Central directional axis and the corresponding left and right directional axes.

Thus, the proposed system is compared with the known at low cost has high quality demagnetization (processing) of the ferromagnetic object through the implementation of more effective stabilization of the exchange rate of the object when exposed to different deflection factors.
