Description

Marine exploration ship fixing system

Technical Field

The utility model relates to the field of marine instrument and equipment industries, in particular to a ship body stabilizing device on a marine exploration ship.

Background

Ocean exploration ships and light boats need survey in the ocean, the measurement operation, wind wave is great in the ocean, and the hull can rock along with the wave, and the hull floats along with the wave peak when the wave crest acts on the hull, and the hull sinks along with the wave trough when the wave trough acts on the hull, can't realize the stable fixed of hull, and the hull can produce violent roll, pitch and heave when the hull is under the great environment of wave during the construction and move to make operation difficulties such as measurement, survey, construction, the operation precision can't reach the requirement.

The existing solution is to break down the anchor and fix the hull by means of a mooring system, but the anchor chain can only fix the hull in one direction, the hull can only substantially achieve position fixation within a certain range, and can also move within a certain range, and in addition, the hull can also swing and rock.

Chinese patent publication No. CN110435819A discloses a ship fixing system and a ship fixing method, including a plurality of anchoring fixing units installed on a deck of a ship body, each anchoring fixing unit includes an anchor and a hydraulic cylinder connected and anchored, and a cylinder body of the hydraulic cylinder is fixedly installed on the deck of the ship body, so as to realize stable fixing of the ship body and avoid violent shaking and heaving of the ship body. When a transition operation is required, the weight blocks need to be lifted off the foundation bed or lifted above the water surface, and then the boat is moved to a new operation position. The weight is suspended outside the boat body, and under the complex water flow condition, the weight can influence the navigation of the boat.

SUMMERY OF THE UTILITY MODEL

The utility model aims to provide a ship body stabilizing device on an ocean exploration ship, which can stabilize a ship body during operations such as measurement, exploration, construction and the like, wherein when the ship does not need to put down a heavy object, the heavy object does not influence the operation of the ship.

In order to solve the technical problem, the ocean exploration boat fixing system comprises a lifting device arranged on a boat, wherein the lifting device is connected with a rope, the rope is connected with a heavy object block, a rope steering device is arranged at the edge of a boat body, and a placing frame for placing the heavy object block is arranged below the rope steering device.

During operation, the rope is placed through the lifting device, the heavy object is placed on the underwater foundation bed, meanwhile, the lifting device keeps certain tension, the tension is between the maximum tension when the heavy object is completely lifted and the minimum tension when the heavy object is completely put down, and therefore the draft of the ship body is between the maximum draft when the heavy object is completely lifted and the minimum draft when the heavy object is completely put down. Therefore, the weight blocks are stably placed on the underwater foundation bed, and the ship body receives pulling force, so that the amplitude of the ship body shaking along with sea waves is reduced. When the needs are transferred, the lifting device is started, the heavy blocks are lifted to leave the foundation bed, or the heavy blocks are lifted to a position above the water surface, then the boat is moved to a new operation position, and the heavy blocks are lowered again to a degree that the tension is appropriate. When the ships and light boats need not transfer the heavy object piece, can promote the position of rack with the heavy object piece to lay the heavy object piece on the rack, avoid the operation that the heavy object piece influences the ships and light boats.

Preferably, the rope diverting means are vertical diverting pulleys.

As a further limitation, the rope turns to the device and includes the shaft, hull edge installation frame, the rope turns to the device and installs on the frame, set up the rectangular groove that can install the shaft on the frame, rectangular groove both ends set up and can fix interior shaft position and the external fixation position of shaft, the shaft can be followed rectangular groove slides, the external fixation position sets up the fixed release device of shaft, the rack sets up in interior shaft position below, the rack is equipped with the opening towards one side of external fixation position, connect thrust unit on the rope turns to the device.
