Safety device of sluice gates

FIELD: construction.

SUBSTANCE: safety device of sluice gates is designed for protection of sluice gates against impact of vessels. The safety device comprises a flexible barrier with shock absorbers, two beams that rotate in the horizontal plane and a truss with drives. Two rotary beams are hingedly fixed on opposite sides of the sluice. The rotary truss is installed on one of the rotary beams. The flexible barrier comprises two ropes. Some ends of ropes are connected to shock absorbers. On free ends of ropes there are elements of a coupling unit. Each rope is equipped with stops. Stops, interacting with ends of rotary beams, provide during assembly the necessary tension of ropes. During installation of a barrier device, rotary beams and truss turn by drives perpendicularly to the sluice in one line. Free ends of two ropes are coupled with a coupling unit. The rotary truss turns with a drive relative to the rotary beam to the side opposite to the impact of the vessel, leaving the rope freely sagging only between rotary beams. Reduced capacity of drives and mass of metal structures is achieved by installation of beams and truss, which are rotary in the horizontal plane.

EFFECT: reduced force of rope tension is achieved by reduction of length of a rope freely sagging between rotary beams.

The invention relates to hydraulic engineering, in particular to a safety device gate gateway.

Known safety device gate gateway in the form of ropes with hydraulic shock, drop to the bottom of the channel (A.S. No. 1266927 from 12.06.1985 year).

The disadvantages of this design are:

the necessity of lowering rope with shock absorbers in the water and protect them from corrosion;

- complication of the maintenance mechanisms of the lifting rope and grommets in the water;

- environmental problems associated with the placement of the rope and mechanisms, using grease in the water.

Known safety device gate gateway Lemen (Germany) (see RIS, p.26 scientific and technical report on the topic №49 "Development of safety devices metal gate Maritime gateways" Saint-Petersburg state University of water communications, St. Petersburg, 2004), containing a flexible barrier in the form of a cable, gidroaerotsentr, lifting the farm-gate with hydraulic hoist, split the node, consisting of a gripping head, a receiving device and transmitting device placed on the end of the farm-gate.

The presence of material in the farm-gate hydraulic aggravates and complicates the design and unidirectional hydraulic shock absorbers leads to a shift from the bottom to the banks of the canal at its inhibition when Nabal.

Known safety device gate gateway installed on the gateways Belinskogo channel deep-water route of St. Lawrence (USA, Canada) (see RIS, p.23 scientific and technical report on the topic №49 "Development of safety devices metal gate Maritime gateways" Saint-Petersburg state University of water communications, St. Petersburg, 2004), which includes a flexible barrier of steel rope, shock absorbers, lifting the farm with the lifting mechanism and the split node. Before installing safety devices the rope loosened. In the working position of the boom stretched across the channel, farm raised.

The disadvantages of this design are:

- the inevitable increase in the mass of the farm and drive power lifting farm with increasing channel width;

- the presence of additional mechanisms for tensioning and loosening of the wire rope before hitch-recepcii, as well as a significant pre-tension force of the rope on the wide channels in order to reduce its deflection from its own weight.

The technical result of the present invention is to reduce the drive power and the mass of metal when installing safety devices, excluding additional mechanisms for regulating the tension decrease tension and p is ogiba rope safety devices in position before the bulk of the ship.

This is achieved in that the safety device gate gateway provides a flexible boom, done, for example, as two ropes, one end of which through the rollers and rods connected with the damper and at the free end of the anchor node hitch, made for example in the form of an eyelet and a hook and swivel farm with the drive installed on the end of one of the two rotatable in a horizontal plane beams, hinged on opposite sides of the gateway.

On turning the farm fixed end of the rope with eyelet with the possibility of breaking through a spring-loaded engagement with the actuator, for example an electromagnet.

At the end of the second pivoting beam fixed end of the rope with hook, made with the possibility of connection-disconnection from the eye through a spring-loaded stopper actuator, for example an electromagnet.

Turning the farm and the second pivoting beam is set so that when you turn it perpendicular to the gateway before the bulk of the ship bar meshed with the hook, thereby connecting two ropes into one flexible boom.

Each rope is equipped with stops interacting with the ends of the rotary beams and providing during installation of the safety devices necessary tension to ensure the minimum bend the and from its own weight.

The reducing power of the actuator and the mass of metal when installing safety devices is achieved by installing on opposite sides of the gateway beams rotating in a horizontal plane.

The exception of additional mechanisms for regulating the tension of the rope in the position of the safety device before the bulk of the vessel is achieved by setting the stops interacting with rotary beams, and a decrease in the tension of the rope is reduced migration sagging rope in position rotary beams, deployed perpendicular to the gateway before the bulk of the ship.

The safety device gate 1 gateway 2 includes a flexible boom, made in the form of the two cables 3 and 4, one ends connected to the absorber 5 by means of rollers 21, 22 and rods 23, and the free ends interconnected by node capture, made, for example, about the bus 6, a hook 7, a spring-loaded stopper 8 with the electromagnet 9, while the free end of the rope 3 is connected to the eyelet 6 and the free end of the rope 4 is connected to the hook 7.

On opposite sides of the gateway 2 swivel set swivel in the horizontal plane of the beams 10, 11 with drives from electrical equipment 12, the mechanism 12 is nicotinamidase to ensure the reversal of the rotary beams 10, 11 at the naval vessel 19. At the end of the swing beam 10 hinged farm 13 with drive ElectronicIndia 14. At the end of the swing beam 11 is made a hole with flats 24 and the groove 25, which has a hook 7, which is connected with the free end of the rope 4 and the groove 25 is made of a width larger than the diameter of the rope 4, but smaller than on the flats of the cylindrical part of a hook 7, which allows for the installation of the rope 4 in the rotary beam 11. At the end of the swivel farm 13 in lodgement-the safety device 15 is fixed, the free end of the rope 3 with the ring 6 by means of a spring-loaded gripper 16, kinematically associated with the electromagnet 17. Rope 3 has a hinge 26 that provides turn it in conjunction with rotary farm 13. The rope 3 is equipped with a stop 18, and a hook 7, which is connected with the rope 4, the stop 27. The lugs 18 and 27 of the cables 3 and 4 are drawn to the ends of the rotary beams 10 and 11, providing the necessary tension and deflection of the rope 3 and 4 that provides the exclude additional mechanisms tensioning ropes 3 and 4.

Flexible boom of the ropes 3 and 4 across the width of the gateway is divided into three parts: from the rollers 21 to the stops 18 and 27 (two parts) and from the stop lugs 18 to 6 (the third part), i.e. the length of each part of sagging rope ~ 3 times smaller than the width of the gateway, which allows to reduce the tension on the rope to achieve the allowable deflection.

The device operates as follows.

With the passage of the vessel 19 rotary beams 10 and 11 (dotted image) deployed actuators with electric 12 along the gateway 2 and the rotary farm 13-drive electroculogram 14 is deployed relative to the rotary beams 10 at an angle, e.g. 30°C...135°, ensuring its place on the wall of the gateway 2.

The end of the rope 4 with the hook 7 is retained by the hole 24 on the rotary beam 11. The end of the rope 3 is held on the rotary farm 13 in lodgement-the safety device 15 spring-loaded grip 16.

Before entering the vessel 19 to the gateway 2 rotary beams 10 and 11 are deployed actuators with electric 12 perpendicular to the gateway 2, the rotary farm 13 turns the drive electroculogram 14 in alignment with the rotary beams 10 and 11.

The eyelet 6 and the hook 7 are linked among themselves and are fixed by a spring-loaded stopper 8, after which the end of the rope 3 raskrasavitsa with swivel farm 13 by embedding a spring-loaded gripper 16 solenoid 17.
