The utility model discloses a multifunctional self weight sinking type anti trawling seabed foundation, which comprises a floating body, an instrument support, a rope cabin, a base bracket, an outer cover and a ballast board. The ballast plate is installed on the base bracket, the weight of the ballast plate is concentrated below the floating body, and the inverted triangle structure is formed with the floating body, which enhances the automatic sinking ability. At the same time, a leg is designed at the bottom of the base support to enhance the stability of the seabed foundation under the action of ocean currents, and reduce the risk of seabed foundation moving and overturning. A rope cabin is installed on the ballast plate, and a rope fixing device is installed in the rope cabin to prevent the floating and knotting of the rope under the action of the seawater. The instrument cabin is equipped with an instrument support, and the acoustic releaser, CTD, ADCP and ocean current meter are fixed on the instrument support by the card sleeve. The spring and dowel pin are designed at the joint of the instrument support and the base bracket, which can strengthen the stability of the instrument support and enhance the success rate of equipment recovery. The design of floating body is separated from instrument support, which not only increases the versatility of the carrying instrument, but also reduces the processing cost. The utility model has the advantages of multifunction self sinking anti trawl seabed base is mainly to increase the number of seabed based instruments and equipped with universal and simplified seabed based deployment process, strengthen the stability of seabed set bottom, improve the success rate of recovery of seabed base, can be used as water sea ocean environment real-time monitoring to provide protection use.
【技术实现步骤摘要】
多功能自重下沉式抗拖网海床基
本技术涉及一种海床基,具体说是一种多功能自重下沉式抗拖网海床基。本技术属于海洋技术监测领域。
技术介绍
海床基作为坐底式海洋监测装置,以其连续、长期测量,受海况影响小以及监测数据质量可靠等优势正在海洋监测
扮演者重要角色。随着海床基的广泛应用,其本身存在的问题也日益突出。其一,海床基搭载设备的单一性,难以满足现阶段对海洋中波、潮、流以及盐度等多方面的监测要求;其二,现阶段海床基搭载设备与浮体多为一体式结构,由于海洋监测设备型号种类繁多,同一种产品不同型号或同一产品不同厂商都存在较大的尺寸差异,浮体设备一体化结构就制约了海床基对设备的通用性,导致了海床基只能搭载固定的设备,缩小了设备的通用性;其三,现阶段海床基常规的布放方式主要有两种:一种是采用A型架或者折臂吊然后配合浮球及声学释放器布放,这种布放的主要缺点是海床基在布放下沉过程中单侧布放,并且要配合浮球及声学释放器,其布放流程复杂,海床基在海底的姿态难以保持水平。若在淤泥质海域,海床基极易斜插入淤泥中,影响了设备的监测精度及安全性,不利于海床基的安全回收。另一种布放方式为对称布 ...
