Description

(54) RISING BUOY

one

The invention relates to the improvement of remotely controlled sign buoys, namely, devices for indicating the diver’s descent point during repair and other types of work on the underwater sections of main oil pipelines.

The closest technical solution to the present invention is a pop-up buoy containing a hermetic case in which a drum with a buoyre associated with a bark-rope, an elastic shell and a gas generator connected with it to the control unit 1 are located.

The known device uses mechanical disconnecting devices such as grippers controlled by solenoids, or other types of locking mechanisms driven by electric motors.

Such types of disconnecting devices are structurally complex, not all of them have sufficient reliability necessary for a long stay under water. In addition, a sufficiently powerful source of electricity is needed to power them.

The aim of the invention is to simplify the design.

To achieve this goal, the buoy is provided with V-shaped brackets located on the body, a float mounted on the opposite side of the elastic sheath, and fixed on the cortex, interacting with the brackets.

FIG. 1 shows a general view of the bu, section; in fig. 2 is a view A of FIG. one;

10 in FIG. 3 - position of the bu after filling with elastic gas; in fig. 4 - position of bu after ascend.

In the hermetic cylindrical housing 1 there is a control unit including 5 ringing receiver 2 and battery 3. Gas generator 4 is located in a separate sealed compartment, which is connected to flexible sheath 6 laid in end part 20 through fitting with built-in valve 5 enclosures. In the opposite part of the body there is a drum 7 with a wound buyrep 8. On the same side, a float 9 is attached to the body, which gives the structure a small positive buoyancy. An antenna 10 for receiving a ring signal is located outside the housing. In addition, two V-shaped brackets 11 are welded to the body. Both brackets are passed through the eye 12 fixed on the coretrose 13. The body 1 is able to rotate around the eye 12. The free end of the buyrep 8 is attached to the eye 12. The lower end of the bore wire 13 is connected with bottom cow 14.

The device works as follows.

When a buoy is installed at the bottom of the reservoir, body 1, having positive buoyancy and being hooked to the eye 12 with V-shaped brackets 11, pulls the bark wire 13, which keeps the buoy from ascending. Since the housing 1 has the ability to rotate around the eye 12, but the rotation axis is outside the housing (extends through the eye plane), the resulting torque causes the housing to assume the position shown in FIG. 1 and 2, i.e. up the float 9.

After receiving the call signal, the gas generator 4 is actuated and the elastic casing 6 is filled with gas. At the same time, the structure acquires additional buoyancy, and since the gas volume in the elastic casing 6 exceeds the volume of cell / cap 9, the casing 1 turns and takes the position shown in FIG. . 3, i.e., the upwardly sheath 6. In this case, the staples 11, under the action of positive buoyancy, come out of engagement with the eye 12 and the buoy floats, unwinding the burep 8.

The buoy of the proposed design is made to be manufactured and in operation, and it does not require special equipment to activate (to give a ringing signal), since a typical generator from the search equipment kit is used as a ringing signal generator.

Because the device is activated immediately before

repair works, the losses of the said buoy are excluded, which, being left for some time on the surface of the water body, is often cut off by ships. Repeated searches of the place of damage require an overhead of working time,

sometimes reaching large quantities.
