Planar sensor for ship log

船用计程仪平面传感器

Abstract

一种船用计程仪平面传感器,克服了现有技术中船用计程仪所采用的传统的杆式传感器电极处于测量杆两侧,测量杆细长,导致其机械强度低、在使用时需伸出船体外面一段距离才能进行测量,在近海浅水航行或通过渔网区时,经常由于测量杆提升不及时而造成测量杆被碰撞损坏的问题;特点是在杆体的底端安装有一个平面底板,在平面底板底部安装电极,所述的平面底板安装在杆体底端安装的螺母内。使用时,平面传感器通过球阀安装在船底,两电极平面与船底外表面相平,不突出船底,不会造成传感器因渔网等物体的刮、撞而毁坏,在保持原电磁计程仪的技术指标、工作稳定性、测量精度优点不变的情况下,提高了传感器的使用寿命。
A planar sensor for a ship log resolves the following problems of the prior art: since the electrodes of the conventional rod type sensor adopted by the ship log are positioned on both sides of the measuring rod and the measuring rod is thin and long, the mechanical strength of the sensor is low, the sensor needs to be extended out of the ship body for a certain distance when being used for measurement, and when the ship sails in an offshore shallow water area or passes through a fishing net area, the measuring rod can often be impacted to damage because of not being lifted in time. The planar sensor is characterized in that a planar bottom plate is mounted on the bottom of a rod body, electrodes are mounted on the bottom of the planar bottom plate, and the planar bottom plate is mounted in a nut mounted on the bottom of the rod body. When in use, the planar sensor is mounted on the bottom of the ship through a ball valve, the planes of the two electrodes are flushed with the outer surface of the bottom of the ship, not sticking out from the bottom of the ship, consequently, the sensor cannot be scraped and impacted by a fishing net or other objects to damage, and under the premise of maintaining the original technical indexes, working stability and measurement precision of the electromagnetic log, the service life of the sensor is prolonged.
