Problems solved by technology

There are certain problems in this positioning method: firstly, the operation is time-consuming and laborious, and the operation of anchoring and anchoring needs to be repeated, and there is still the problem of inaccurate positioning. At the same time, it is difficult to ensure that the navigation track is standard when the barge sails between two points after positioning. Straight line, so the fish reefs dropped between two points are not arranged in a straight line

Embodiment Construction

[0008] The specific implementation manner of the present invention will be described below with reference to the accompanying drawings. Such as figure 1 Shown: a method for locating and delivering artificial fish reefs. First, after the barge sails to the first delivery position, GPS positioning is performed, and at the same time, the first anchor with the anchor chain is thrown into the water, and then the barge continues to sail to the second delivery position. During the voyage, the anchor chain is continuously loosened. After the barge reaches the second release position, GPS positioning is carried out. The second anchor with the anchor chain is also thrown into the water, and then both anchor chains are tightened. After tension, the barge is in the On the line between the two points of the first delivery location and the second delivery location, and then download the navigation between the first delivery location and the second delivery location when the two anchor chain...

Abstract

The invention discloses a method for positioning throwing of artificial fish reefs. The method is characterized by comprising the steps of conducting global position system (GPS) positioning after a barge sails to a first throwing position, then throwing a first anchor with an anchor chain into water, releasing the anchor chain during the period when the barge continues to sail to a second throwing position, conducting GPS positioning after the barge arrives at the second throwing position, also throwing a second anchor with an anchor chain into the water, tightening two anchor chains, sailing between the first throwing position and the second throwing position on the condition that the two anchor chains are in the tightened state throughout, collecting and releasing anchor chains correspondingly during sailing, throwing fish reefs at a plurality of throwing points between the first throwing position and the second throwing position, and conducting GPS positioning at each of the throwing points. The method is convenient to operate, time-saving, effort-saving, capable of guaranteeing that artificial fish reefs are thrown in a line and applicable to straight-line fish reef throwing in shallow waters.

Description

technical field [0001] The invention relates to a method for positioning and placing artificial fish reefs, in particular to a method suitable for line-by-line placing of artificial fish reefs in grid-like layout and row-like layout in relatively shallow waters. Background technique [0002] When launching artificial reefs in the ocean, the traditional positioning method is: after the barge arrives at the launching position, perform GPS positioning, and at the same time adjust the attitude of the barge to keep it basically at the launching position, or drop anchor to realize that the barge is at the launching position positioning. There are certain problems in this positioning method: firstly, the operation is time-consuming and laborious, and the operation of anchoring and anchoring needs to be repeated, and there is still the problem of inaccurate positioning. At the same time, it is difficult to ensure that the navigation track is standard when the barge sails between two...
