Description

A device for deployment and recovery of underwater equipment

technical field

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

Background technique

During sea trials, it is often necessary to deploy and recover objects such as boats, underwater vehicles, and mines. Currently, ship cranes are usually used for deployment and recovery. During the deployment and recovery process, multiple operators are required to work together. In the case of severe sea conditions, the ship and the suspended object will shake a lot, which will have a serious impact on the personal safety of the operators on board. At the same time, during the hoisting process, the object shakes too much and often collides with the hull, causing damage to the hoisted object and the hull. During the recycling process, operators are often required to fix and drag the ropes, which is time-consuming, laborious and unsafe.

Patent 201610996269.9 discloses a "lifeboat launching device", which is suitable for the launching process of a marine lifeboat with a specific structure, but is difficult to apply to the lifting of general underwater vehicles, mine bodies and other objects. It is difficult to put the lifeboat in the initial state of the deployment process, and the deployment efficiency is low. If the personnel do not control the rope well during the hoisting process, shaking will still occur, and the safety has not been effectively solved. The lowering device does not consider the recovery process, which has great limitations in practical application.

Invention patent 201610863849.0 proposes a "deployment and recovery method for unmanned surface vehicles". The deployment and recovery requires maneuvering the aircraft to a fixed position, and then using a long bamboo pole to take out the guide rope. It is difficult to align the crane hook during the operation. For the conical hammer module, the recovery process is complicated and requires personnel assistance, making the operation difficult. Since the entire recovery process is carried out by using guide ropes, the aircraft is prone to violent shaking, which is easy to damage the hull and threaten the safety of people on board.

Two winches 4 are fixedly installed on one end of the mobile platform 2 respectively, and two supports are installed on the other end of the mobile platform 2 respectively. The support 6 is a semi-circular arc structure, and the two supports are installed symmetrically, and 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, and the inner surface of the support 6 is evenly distributed. A spring 7 is used to protect the suspended object 10 and the support 6. The two brackets 6 are fixedly connected by the bracket connecting rod 11, the bracket connecting rod 11 is connected with the hydraulic cylinder 3 on the mobile platform 2, and the hydraulic cylinder 3 is used to control the drive bracket 6 to rotate around the hinge point of the bracket; the wire rope drawn by the winch 4 5 bypass the fixed pulley 8 on the support 6 and hang the object 10 through the remote release hook 9; the two winches 4 run synchronously. Hanging object 10 is placed in the inside of two supports 6, and two supports 6 are close to the two ends of suspended object respectively, and support 6 connecting rod 11 guarantees that two supports 6 are in the same horizontal position all the time in the process of hanging.

In the present embodiment, pneumatic net gun 13 comprises net rope 14, throws net 15, net pendant 16, and pneumatic net gun 13 is connected with throwing net 15 by net rope 14, and pneumatic net gun 13 is used for throwing net and pushing out, in Under the gravitational effect of the net pendant 16, the object that needs to be recovered is netted, and the net mouth is drawn up to drag the object back.

In the present embodiment, there are at least three fixed pulleys 8 distributed circumferentially along the upper surface of the bracket; there should be a fixed pulley 8 at the top of a bracket; 5 role.

The working process and specific steps of the underwater equipment deployment and recovery device of this 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 support 6 . Under the protection of support 6, even if the sea condition is harsh, the object will not swing and shake with the wire rope. When the movable platform 2 moves along the parallel guide rail 1 to the cut-off state of the horizontal stroke, the hydraulic cylinder 3 starts to drive the support 6 to rotate. When the hydraulic cylinder 3 rotates to a preset angle, the winch 4 starts to work, and the hoisting object 10 is started to be hoisted by the wire rope 5 . When the suspended object 10 enters the state of entering water, the remote control release hook 9 generates an action to release the suspended object. So far, the hanging process is over. When the horizontal stroke is cut off, the mobile platform 2 stretches out to a distance of 1.5m from the side of the ship to prevent the suspended object from colliding with the ship during lowering.

When performing recovery tasks, the pneumatic net gun 13 is aimed at the direction of the object to be recovered, and throws the net 15 out under the action of high pressure. Throwing net 15 is launched in the air, and under the gravitational effect of net pendant 16, object is netted, and net mouth is tightened up simultaneously. Pneumatic net gun 13 pulls net rope 14 then, and object is dragged back to the water surface of support 6 below, and remote control releases hook 9 and throws net 15 and is connected, and hanging device starts lifting object. While the support 6 rotates, the winch 4 lifts the suspended object through the wire rope 5 . When the bracket 6 rotates to the cut-off state of the horizontal stroke, the hydraulic cylinder 3 stops, and the mobile platform 2 starts to move along the parallel guide rail 1, and finally reaches the initial state. At this point, the recovery process is over.
