Description

高精度海洋磁力测量拖曳装置  High precision ocean magnetic measuring towing device
技术领域： Technical field:
本发明涉及一种 海洋磁力测量 辅助装置，尤其是一种吃水深度稳定、磁测位置定位准确且可防止与水下障碍物碰撞而损坏磁力仪的 高精度海洋磁力测量拖曳装置。 The invention relates to a marine magnetic measurement The auxiliary device, in particular, a high-precision marine magnetic measuring towing device which is stable in draft water, accurate in positioning of the magnetic measuring position and capable of preventing damage to the magnetometer by collision with underwater obstacles.
背景技术： Background technique:
目前，拖曳测量模式是获取海洋地理空间磁场信息的主要手段。公知的拖曳测量方法是将海洋磁力仪安置于拖曳装置上，由测船用缆绳直接拖带拖曳装置进行航行测量，即实时测量磁测位置（海洋磁力仪所处水平位置）的磁力。为了避免船磁干扰，按有关作业规范，拖带缆绳的长度一般为测船长度的三倍。由于现有的拖曳装置只是简单的无磁性浮球或救生衣，存在如下的问题： At present, the tow measurement mode is the main means to obtain the magnetic information of the ocean geospatial. The known drag measurement method is to place the ocean magnetometer on the towing device, and the tow device is directly towed by the ship cable for navigation measurement, that is, the magnetic force of the magnetic measurement position (the horizontal position of the ocean magnetometer) is measured in real time. In order to avoid ship magnetic interference, the length of the towing cable is generally three times the length of the ship according to the relevant work specifications. Since the existing towing device is simply a non-magnetic float or life jacket, the following problems exist:
（ 1 ）测船航速对磁力仪的吃水深度（即磁力仪距海面的深度）影响较大，当测船航速较低时，磁力仪的吃水深度等于设定的静态吃水深度，即磁力仪距浮球或救生衣的深度；当测船航速较高时，磁力仪受到拖带牵引力的作用产生一定的上浮（其上浮幅度与航速成正比），磁力仪吃水深度小于设定的静态吃水深度。磁力仪吃水深度的变化会影响磁力测量值归算至统一基准面的精度，也会影响对海底磁性目标的探测分辩率。 ( 1 The speed of the surveying ship has a great influence on the draft of the magnetometer (that is, the depth of the magnetometer from the sea surface). When the speed of the survey vessel is low, the draught depth of the magnetometer is equal to the set static draught depth, that is, the magnetometer is from the float. Or the depth of the life jacket; when the ship's speed is high, the magnetometer is subjected to the towing force to produce a certain floating (the floating amplitude is proportional to the speed), and the magnetometer's draft is less than the set static draft. The change in the depth of the magnetometer's draught affects the accuracy of the magnetic measurement to the uniform datum and also the detection resolution of the submarine magnetic target.
（ 2 ）磁测位置是由测船的位置按直线假设推算得到的，定位误差大，测量精度低，尤其是当测船及拖曳装置受风、流的影响，或者当测船及拖曳装置转弯，即航迹不处于直线状态时，推算得到的磁测位置误差更大，进一步降低了磁力测量的精度。 ( 2 The magnetic measurement position is calculated from the position of the ship according to the straight line assumption. The positioning error is large and the measurement accuracy is low, especially when the ship and the towing device are affected by wind and flow, or when the ship and the towing device turn, When the track is not in a straight line state, the calculated magnetic measurement position error is larger, which further reduces the accuracy of the magnetic measurement.
（ 3 ）在搜寻失事沉船、锚链、管道、海缆、水雷等水下目标时，或在水产养殖区作业时，测量拖体常与水下障碍物发生碰撞，昂贵的磁力仪则会因碰撞而损坏或丢失，增加了测量成本。 (3 When searching for underwater targets such as wrecks, anchor chains, pipelines, submarine cables, mines, etc., or when working in aquaculture areas, the measuring tows often collide with underwater obstacles, and expensive magnetometers will collide. Damage or loss increases the cost of measurement.

在 导流防护罩前端设有碰撞检测传感器，所述碰撞检测传感器的输出与数据处理模块相接。 A collision detecting sensor is disposed at a front end of the flow guiding shield, and an output of the collision detecting sensor is connected to the data processing module.
