(54) MACHINE FOR WATER BOTTOM WORKS

one

The invention relates to machines for excavating and moving soil and can be used for underwater hydraulic engineering construction, dredging, as well as in the development of underwater mineral deposits.

A known machine for working at the bottom of reservoirs, including underwater and surface parts. The underwater part is represented by a tractor, which is designed for dredging, and the surface part is made in the form of an amphibious longline equipped with a power plant, the underwater part is equipped with attachments and made as an underwater crawler truck with an operator capsule equipped with a control system 1.

The disadvantage of the machine is the complexity of the design and control.

The closest technical solution to the proposed is a machine for work on the bottom of a reservoir, including a working vessel floating on the surface of the water, equipped with a power plant, an underwater bulldozer with a drive and systems

control and life support, with the bulldozer moving along the bottom of the reservoir by remote control from the working vessel. The working vessel and the underwater bulldozer are interconnected by a ball joint with the help of hinged knots and connecting bar so that the working vessel can move in a vertical plane only along the hull of the bulldozer, which can freely rotate at an arbitrary angle. Also by car

10, for work at the bottom of the reservoir, a traction mechanism is installed, the compressive force of which returns the working vessel and the bulldozer body to a certain position 2.

The main disadvantage of the machine is low work efficiency

15 for leveling the bottom and underwater excavation, which is explained by its low maneuverability in the conditions of shallow depths and the inability of the bulldozer to emerge for its transportation from one working object

20 to another.

In addition, the remote control system of the bulldozer at the top is very large | 1 v-falsity, the presence of additional forensic equipment.

geodetic masts extending to the surface, increasing the overall dimensions of the bulldozer.

The purpose of the invention is to increase the efficiency of work on the leveling of the bottom and subsea excavation at shallow depths.

This goal is achieved by the fact that the connecting bar is made in the form of a composite tubular column with a tilting drive and an air valve, the lower part of which is made in the form of an operator's capsule mounted on the underwater bulldozer by means of a hinge assembly that is detachable, and the control system of the underwater bulldozer is equipped with a system of hydrostatic levels located along the perimeter of the underwater bulldozer and guides of the block.

In addition, in this mask, the life support system includes an installation for supply and exhaust ventilation, a diving ladder located inside the composite tubular column, an emergency hatch and cylinders with a supply of compressed air.

The drawing shows schematically a proposed mashina when working at the maximum depth and vertical position of the connecting beam.

Maschina bl work at the bottom of the reservoir contains floating on the surface of the water working vessel 1, United sharnarno. with underwater bulldozer 2. Working vessel 1 is equipped with power plant 3, and underwater bulldozer 2 with hydraulic drive 4 and control system 5, the console is located in the lower part of the connecting bar, made in the form of a composite tubular column b with hydraulic drive 7 tilt and air valve 8. Bottom: 1 part of the connecting bar is made in turn in the form of an operator's capsule 9, which is connected to the underwater bulldozer by a split hinge unit 10. The control system of the underwater bulldozer is equipped with guide blocks 11 and system 12 hydrostatic levels.

The life support system of the underwater bulldozer includes installation 13 for supply and exhaust ventilation, a diving ladder 14 located inside the composite tubular column 6, an emergency hatch 15 and cylinders 16 with a supply of compressed air. The working vessel 1 with a connecting bar in the form of a composite tubular column 6 is connected by means of a hinged node 17.

Machine for work on the bottom of reservoirs works as follows.

The maschine is delivered to the work site by means of a watercraft, since the working vessel is not self-propelled. Transportation underwater bulldozer 2 is provided afloat, for

which, with the help of the tilt actuator 7 of the composite tubular column 6, the underwater bulldozer 2 rises and is kept afloat due to the buoyancy of the working vessel 1 and the connecting bar in the form of the composite 5 tubular column 6. The working area at the bottom of reservoirs can also move under its own power, since the supporting area of the underwater bulldozer 2 prevents it from falling on weak soils.

 The operation of the machine for working at the bottom of the reservoirs is carried out from the console of the control system 5, located in the capsule 9 of the operator, which is the lower part of the connecting beam, made in the form of

5 composite tubular columns 6. The control panel of the control system 5 receives the data of the system 2 hydrostatic levels about the orientation of the masking for work on the bottom of the reservoirs relative to the bottom. From the console of the control system 5, the signals go to the actuator 4

0 underwater bulldozer 2, made hydraulically. M, and to the working body of the machine, which comes into operation, as well as to drive 7 tilt composite tubular column 6. Underwater bulldozer 2 mashiny

5 operations at the bottom of reservoirs move along the bottom of the reservoir and provide leveling of the bottom and underwater excavation of soils. In installation, zero visibility, as well as for laying the submarine cables, use the guide blocks 1 of the system 5

0 controls, by means of which the cable is pre-tensioned, along which the machine moves to work at the bottom of the reservoirs.

With a sufficiently flat bottom relief, the connecting bar in the form of a composite tubular column 6 is attached to a vertical position and fixed by the hinged nodes 10 and 17. Then the working vessel 1 rises above the surface of the water, thus significantly reducing the effect on the

o Works at the bottom of reservoirs wave loads and resistance to movement. In case of uneven bottom of the reservoirs, for the safety of work, the working vessel is lowered into the water and the hinge joints 10 and 17 are released.

5 The bottom of the reservoir controls the operator 1 operator, which is located in the operator’s capsule 9, where it descends from the working vessel 1 along the diving ladder 14 of the connecting bar in the form of a composite tubular column 6. The operator is provided with air at atmospheric pressure by installing 13 supply ventilation with normal open position of air valve 8. During air, air valve 8

closes, which interferes with flooding the operator capsule 9. In the event of failure of the installation 13, the supply and exhaust ventilation automatically switches on the output of the tank from the cylinders 16 with a margin

compressed air and emergency alarm. The operator must immediately leave the underwater part of the machine for work at the bottom of the reservoirs and come to the surface via the diving ladder 14. If it is impossible to climb to the surface through the diving ladder 14, the operator leaves the capsule 6 through the emergency hatch 15 using an individual breathing apparatus.

The reservoir machine is a universal earth-moving machine, since its underwater bulldozer can be equipped with various replacement equipment, allowing us, nm to dry, cut, scale, move and plan submerged soils and bulk materials. Platform with positive buoyancy can also serve as a working ship of the machine.
