The USSR №1195178) 4 01 5 priority from 15.01.1981 g) containing a flexible strand connected at one end with the moving unit, the other with a fixed point, a drum for winding flexible strands, guides and potenzmitteln rollers interacting with the thread, a bracket mounted on the moving unit, the base frame and two brakes.

A disadvantage of the known devices is the inability to measure with it sediment and trim moving models floating tools.

It is also known towing device with six degrees of freedom (prototype - see U.S. patent No. 3916813 And IPC 63 21/64, published. 04.11.1975 g) containing locomotion by land towing a cart attached to it a bracket, made in the form of console, with the device for measuring the pitch of the model.

The disadvantage of this towing device is the inability to measure with it sediment moving models floating tools.

Appl is to measure displacement models floating funds for their testing in a towing tank basin.

The solution of the stated problem is achieved in that the device for measuring sediment and trim models floating means containing bracket, made in the form of console, mounted on the towing carriage and having a device for measuring the pitch model, the console bracket is made, for example, of channel, and the device has a flexible strands, guide rollers and support rollers, while in the side wall of the bracket is made a longitudinal groove, in which is mounted for movement along the groove of the guide rollers, and at the end of the bracket attached supporting rollers, flexible thread pinned to the model in place of measuring precipitation, around guide roller and passes through it to the other end of the flexible filament attached to the counterweight placed in the guides of the receiver balances, this device has a recording device with a linear position sensor on each flexible strands, made for example in the form of a pointer arrow on the panel with graduated scales installed on the bracket.

The use of the claimed device will allow you to extend the range of the measured parameters when testing models floating means and control the network: Fig.1 - General view of the device placed on the towing carriage; Fig.2 is a view As in Fig.1; Fig.3 - view of B in Fig.2; Fig.4 - view In Fig.2.

Device for measuring sediment and trim models floating means includes a bracket 1 made in the form of console, mounted on the towing carriage 2 and having a device for measuring the pitch model, flexible strands 3, guide rollers 4 and the supporting rollers 5. Bracket-console can be performed, for example, of channel. In the side wall of the bracket 1 has a longitudinal groove 6, which is mounted for movement along the groove of the guide rollers 4, and at the end of the bracket attached supporting rollers 5. Flexible filament 3 is fixed on the model 7 in place of measuring precipitation, around guide roller 4 and passes through it. To the other end of the thread attached to the counterweight 8, posted in the guides of the receiver balances 9. The device for measurement is the recording device 10 with the linear position sensor on each flexible strands, made for example in the form of a needle pointer 11 on the panel 12 with a graduated scale 13 mounted on the bracket 1.

The proposed device operates as follows. The tested model of Plav the sediment and trim, attach the ends of the flexible thread. Precipitation and trim models arising in the process of towing, fix by means of the recording device 10.
