Method for accurately throwing artificial reefs in open sea area

Abstract

The invention relates to a technology of artificial reef construction, in particular to a method for accurately throwing artificial reefs in the deep water open sea area far away from the bank. According to the principle that a triangle is stable, a throwing ship is located at three points and is accurate in location and good in stability, the throwing distance of a ship anchor cable is 3-5 times as large as the water depth, effects of sea flow and the flowing speed on the artificial reef throwing can be avoided by adjusting the three-point-located anchor cable, accurate artificial fish throwing can be conducted in the open area with large water depth and rotation flow, the throwing efficiency and accuracy are high, an excavator is adopted as the throwing device, and the throwing device is flexible to operate and safe in operation on the throwing ship.

Description

[0001] technical field [0002] The invention relates to the technology of artificial fish reef construction, in particular to a method for accurately placing artificial fish reefs in deep water open sea areas far from the shore. Background technique [0003] Marine ranching is a new model of marine resources development and utilization, which has changed the previous fishery production mode based on simple fishing and facility breeding, and basically solved the problems of resource depletion caused by local pollution and overfishing, and aggravated diseases caused by offshore farming. It is a major change in the production mode of marine fishery. The construction of marine ranching is an effective measure to realize the sustainable utilization of marine biological resources and protect the marine ecological environment. Artificial reefs are an important part of the construction of marine ranching, and play an important role in restoring the fishery environment and multiply...

Problems solved by technology

The construction of marine ranching is an effective measure to realize the sustainable utilization of marine biological resources and protect the marine ecological environment. Artificial reefs are an important part of the construction of marine ranching, and play an important role in restoring the fishery environment and multiplying fishery resources. The current fish reef technology The focus of research is still on the scientific research on the mechanism of artificial fish reef environment, but there is no in-depth research on artificial fish reef deployment technology and methods as an important part of artificial fish reef construction

[0003]The placement of existing artificial fish reefs all directly depends on the free operation of the placement unit, mainly using the lifting device to directly put the artificial fish reefs into the position to be placed. In seawater, the safety, efficiency, and accuracy of this delivery method are low, and the artificial reef is easily affected by inertia and currents during the falling process and deviates from the delivery position. After delivery, it is far from the planned layout before delivery, causing artificial fish The construction effect of the reef is not good; although "CN201010292697.6 Artificial fish reef delivery method in open sea area" patent application document discloses the artificial fish reef delivery method in the open sea area of ​​precise positioning, there are still following deficiencies:

[0005]2. Due to the influence of the flow direction and velocity of the sea current, there are errors in the accuracy of fish reef placement; the swirling current changes the flow direction with the tide, and the flow velocity will also change , the flow direction and velocity of the sea current can cause the anchor to leave the position, causing the release position of the ship and fish reef to deviate from the original planned release position;

[0006] 3. The work efficiency of releasing fish reefs is low and the operation time is long
