The invention relates to a damping device installed in a primary connection to reduce the effort in them from dynamic loads acting on the supporting means of indigenous means. A device for depreciating the basic connection of the floating means is known, which has a rigid lever located on the bottom of this means its shoulder is a shock absorbing floating tank connected to the root link 1.

A disadvantage of the known device is that it does not allow to reduce the rolling of a floating object from the action of the dynamic forces of the reactions of the main bonds.

The purpose of the invention is to reduce the effect on the craft of the dynamic forces of the reactions of primary bonds.

The goal is achieved by the fact that in the device for damping the main link of the floating means, which contains a rigid lever located under the bottom of this means with a shock absorbing floating tank attached to the end of its shoulder, the said link is double-shouldered and L-shaped, moreover, the end of the second shoulder is provided with a butt, through which the root link is freely passed, while the lever in the knee is hinged on the bottom of the floating craft, made with the roof open below, in which is located hauling buoy capacity with the possibility of vertical movements.

FIG. 1 shows a part of a mainframe with a damping device, plan view; in fig. 2 shows section A-A in FIG. one.

The device contains an L-shaped double-arm lever 1, fixed in the knee with the help of hinge 2, on the bottom of the main floating craft 3. At the end of one arm (horizontal) lever 1, there is a shock absorbing floating tank 4, which is enclosed with the possibility of free vertical movement in the open to bottom niche 5 in the bottom of the craft 3. Anchor link 6, attached to

shock absorbing floating tank, passed through the butt 7, located at the end of the other arm of the lever 1.

The device works as follows.

When tensioning the crust 6, the force is transmitted to the damping floating tank 4, which, under the action of the vertical force component, comes out of the niche 5, is submerged and turns around the center 2 double-arm lever 1. At the same time, torque is not transmitted. In the process of reducing the force in the main link, the reducing forces of the displacement force the newly damped buoyant tank 4 to the poor 5 at the bottom of the main boat 3, which during all phases of the cycle of decrease or increase in the force in the main link 6 is in a stabilized mode.

In addition, the linkage 6, passed through the butt 7, is limited in its vertical movement during its tension, which allows it to ensure the preservation of the safe submerged clearance of the main floating craft 3 if it is necessary to moor another floating object 8 thereto.

Thus, the proposed device makes it possible to reduce the rolling motion of the primary object and to ensure the specified underwater clearance.

The effectiveness of the proposed device lies in the fact that, along with ensuring the specified damping parameters, the conditions for moored floating equipment behind an indigenous object equipped with the proposed device for depreciation are significantly improved. Favorable conditions are created for placing various devices and equipment on the main floating craft, whose operation is limited by pitching conditions (for example, drilling, radio electronic, etc.).

The shock-absorbing device can be widely used in equipping floating berths, drilling platforms, radios and other floating equipment.
