2kW直筒型集鱼灯水中照度分布及合理配置研究

Underwater irradiance and optimal allocation of 2 k W straight type fish aggregation lamps

根据2 k W直筒型集鱼灯的实测配光分布,以大型光诱鱿钓渔船"新世纪52号"为例,对该船的水中照度分布进行了计算。结果表明:渔船集鱼灯总功率为360 k W时,10.000 lx的等照度曲线水平方向最远约为80 m,水深方向为32 m;0.100 lx照度最深可约至50 m,最远约为260 m;当总功率减为180 k W时,等照度曲线所在水层仅减少约5 m。以0.010 lx为诱集鱿鱼的最低照度,集鱼灯功率从180 k W增加到360 k W,有效诱集距离从620 m增加到750 m,约能增加21.1%;如能将该船的灯高增大0.5 m,则可增加12.0%的有效水体体积;如能将灯距增大0.05 m,则可增加4.4%的有效水体体积。

Based on the actual measurement of 2 k W straight type fish aggregation lamps,we calculated the underwater illumination distribution of the squid jigging vessel Xinshiji No. 52. The results show that when the total power was 360 k W,the iso-illuminance curve contours of 10. 000 lx were at the depth of 32 m; in horizontal direction,it reached 80 m. The curve contours of 0. 100 lx were at 50 m vertically and 260 m horizontally. When the total power was 180 k W,the curve contours reduced about 5 m in depth. Regarding 0. 010 lx as the lowest limit to attract squid,if the power was increased from 180 k W to 360 k W,attracting distance could be increased from 620 m to 750 m,and 21. 1% of effective attracting distance increased horizontally. If the lamps＇ height increased for 0. 5m,12. 0% of the effective water volume increased. If the lamps＇ space increased for 0. 05 m,4. 4% of the effective water volume increased.
