Description

Device for laying and recovering equipment in water

Technical Field

The invention relates to the technical field of marine equipment, in particular to a device for distributing and recovering underwater equipment.

Background

In a sea test, objects such as boats, underwater vehicles, mine operation and the like are required to be arranged and recovered frequently, and at present, a crane on a boat is used for arrangement and recovery frequently. In the process of distribution and recovery, multiple operators are required to carry out cooperative operation. Under the condition of severe sea conditions, the ship and the hung object can shake greatly, and the personal safety of operators on the ship is seriously affected. Meanwhile, in the hoisting process, the object shakes too much and often collides with the ship body, so that the hoisted object and the ship body are damaged. In the recovery process, an operator is often required to fix and drag the rope, which is time-consuming, labor-consuming and unsafe.

The patent 201610996269.9 discloses a lifeboat lowering device, which is suitable for the lowering and releasing process of a lifeboat for a ship with a specific structure, and is difficult to be suitable for the lifting and releasing of general underwater vehicles, mines and other objects. The lifeboat is placed in the initial state of the laying process, so that certain operation difficulty is caused, and the laying efficiency is low. If the rope is not well controlled by personnel in the hoisting process, the rope still shakes, and the safety is not effectively solved. The lowering and releasing device does not consider the recovery process, and has large limitation in practical application.

Detailed Description

The embodiment is a device for distributing and recovering equipment in water.

Referring to fig. 1 to 7, the underwater equipment laying and recovery device of the embodiment is composed of a moving platform 2, a parallel guide rail 1, a hydraulic oil cylinder 3, a winch 4, a steel wire rope 5, a bracket 6, a spring 7, a fixed pulley 8, a remote control release hook 9 and a bracket connecting rod 1; the parallel guide rail 1 is fixed on the ship body 12, the moving platform 2 is located on the upper portion of the parallel guide rail 1 and is installed in a matched mode with the parallel guide rail 1, and the moving platform and the driving motor are matched to move along the parallel guide rail 1. The two winches 4 are respectively and fixedly arranged at one side end part of the movable platform 2, and the two supports are respectively arranged at the other side end part of the movable platform 2. The support 6 is of a semi-circular arc structure, the two supports are symmetrically installed, the center of the support 6 and the center of the winch are located on the same vertical plane, two groups of fixed pulleys 8 are symmetrically fixed on the two supports 6 respectively, and a plurality of springs 7 are uniformly distributed on the inner surface of the support 6 and used for protecting a hanging object 10 and the support 6. The two brackets 6 are fixedly connected by a bracket connecting rod 11, the bracket connecting rod 11 is connected with a hydraulic oil cylinder 3 on the mobile platform 2, and the hydraulic oil cylinder 3 is used for controlling the driving bracket 6 to rotate around a bracket hinge point; a steel wire rope 5 pulled by the winch 4 is connected with a hoisting object 10 by a remote control release hoisting hook 9 by bypassing a fixed pulley 8 on the bracket 6; the two winches 4 are operated synchronously. The hoisting object 10 is placed inside the two supports 6, the two supports 6 are respectively close to two ends of the hoisted object, and the connecting rods 11 of the supports 6 ensure that the two supports 6 are always positioned at the same horizontal position in the hoisting process.

In this embodiment, the pneumatic net gun 13 includes a net rope 14, a throwing net 15, and a net weight 16, the pneumatic net gun 13 is connected to the throwing net 15 through the net rope 14, the pneumatic net gun 13 is used for ejecting the throwing net, and the object to be recovered is caught under the gravity of the net weight 16, and the net mouth is closed to pull the object back.

In the embodiment, at least three fixed pulleys 8 are circumferentially distributed along the upper surface of the bracket; a fixed pulley 8 is arranged at the top end of one bracket; the fixed pulley 8 serves to adjust the direction of the wire rope 5 and, at the same time, to tension the wire rope 5.

The working process and the specific steps of the underwater equipment arrangement and recovery device of the embodiment are as follows:

when performing a deployment task, the device is first in an initial state. At this time, the suspended object 10 is placed in the rack 6. Under the protection of the bracket 6, even if the sea condition is severe, the object cannot swing and rock along with the steel wire rope. When the movable platform 2 moves to the horizontal stroke stop state along the parallel guide rails 1, the hydraulic oil cylinder 3 starts to drive the bracket 6 to rotate. When the hydraulic oil cylinder 3 rotates to a preset angle, the winch 4 starts to work, and the hoisting object 10 starts to be hoisted through the steel wire rope 5. When the hung object 10 enters a water entering state, the remote control release hook 9 acts to release the hung object. And ending the hoisting process. When the horizontal stroke is in a stop state, the movable platform 2 extends out of the ship board by a distance of 1.5m, so that the suspended object is prevented from colliding with the ship in the process of lowering.

When the recovery task is executed, the pneumatic net gun 13 is aligned to the direction of an object to be recovered, and the throwing net 15 is pushed out under the action of high pressure. The throwing net 15 is unfolded in the air, and under the gravity action of the net drop 16, the object is caught and the net opening is tightened. Then the pneumatic net gun 13 pulls the net rope 14 to drag the object to the water surface below the bracket 6, the remote control release hook 9 is connected with the throwing net 15, and the hanging device starts to lift the object. The winch 4 lifts the hoisted object by the wire rope 5 while the bracket 6 rotates. When the bracket 6 rotates to a horizontal stroke stop state, the hydraulic oil cylinder 3 stops acting, and the mobile platform 2 starts to move along the parallel guide rails 1 and finally reaches an initial state. By this point, the recycling process ends.
