中文说明: 近浅海观测网的传输节点由浮标系统、系泊系统和水声通讯系统组成(如图1所示)。某型传输节点的浮标系统可简化为底面直径2m、高2m的圆柱体,浮标的质量为1000kg。系泊系统由钢管、钢桶、重物球、电焊锚链和特制的抗拖移锚组成。锚的质量为600kg,锚链选用无档普通链环,近浅海观测网的常用型号及其参数在附表中列出。钢管共4节,每节长度1m,直径为50mm,每节钢管的质量为10kg。要求锚链末端与锚的链接处的切线方向与海床的夹角不超过16度,否则锚会被拖行,致使节点移位丢失。水声通讯系统安装在一个长1m、外径30cm的密封圆柱形钢桶内,设备和钢桶总质量为100kg。钢桶上接第4节钢管,下接电焊锚链。钢桶竖直时,水声通讯设备的工作效果最佳。若钢桶倾斜,则影响设备的工作效果。钢桶的倾斜角度(钢桶与竖直线的夹角)超过5度时,设备的工作效果较差。为了控制钢桶的倾斜角度,钢桶与电焊锚链链接处可悬挂重物球。
English Description:
The transmission node of near shallow water observation network is composed of buoy system, mooring system and underwater acoustic communication system (as shown in Figure 1). The buoy system of a transmission node can be simplified as a cylinder with a bottom diameter of 2M and a height of 2m, and the mass of the buoy is 1000kg. The mooring system consists of steel pipe, steel barrel, heavy ball, electric welding anchor chain and special anti dragging anchor. The mass of the anchor is 600kg, the ordinary chain link without stop is selected, and the common models and parameters of the near shallow water observation network are listed in the attached table. There are 4 sections of steel pipe, each section is 1m in length, 50mm in diameter, and the mass of each section is 10kg. The angle between the tangent direction of the end of the anchor chain and the anchor and the seabed should not exceed 16 degrees, otherwise the anchor will be towed and the node will be lost. The underwater acoustic communication system is installed in a sealed cylindrical steel drum with a length of 1m and an outer diameter of 30cm. The total mass of the equipment and the steel drum is 100kg. The steel drum is connected with the fourth section steel pipe on the top and the electric welding anchor chain on the bottom. When the steel barrel is vertical, the working effect of underwater acoustic communication equipment is the best. If the steel barrel is inclined, the working effect of the equipment will be affected. When the inclination angle of the steel barrel (the angle between the steel barrel and the vertical line) exceeds 5 degrees, the working effect of the equipment is poor. In order to control the inclination angle of the steel drum, the heavy ball can be suspended at the joint of the steel drum and the electric welding anchor chain.
