CN104989913A 一种海底管道漏磁内检测装置 无效 - 驳回

一种海底管道漏磁内检测装置
摘要：
本发明公开了一种海底管道漏磁内检测装置，涉及海底油气管道检测技术领域。该海底管道漏磁内检测装置包括中心骨架以及安装于所述中心骨架两端的支撑皮碗，所述中心骨架上沿圆周方向设置有多个磁路模块，所述磁路模块通过弹性支撑组件安装于所述中心骨架上，并在所述弹性支撑组件的弹力作用下始终与所述海底管道的内壁相贴合。本发明提供的海底管道漏磁内检测装置的磁路模块在弹性支撑组件的弹力作用下能够始终与海底管道的内壁相贴合，当管道的内径发生变化时，检测装置的形状能够进行自适应的改变，因此磁路模块与海底管道内壁之间始终能够实现磁路闭环，保证检测装置沿途检测无遗漏点，大大提高了检测精度。
摘要（英）：

The invention discloses a submarine pipeline magnetic leakage internal detection device, and relates to the technical field of submarine oil and gas pipeline detection. The submarine pipeline magnetic leakage internal detection device comprises a central framework and supporting leather cups installed on two ends of the central framework, a plurality of magnetic circuit modules arranged on the central framework along the circumferential direction, the magnetic circuit modules are installed on the central framework through elastic support assemblies, and the magnetic circuit modules always adhere to the inner wall of a submarine pipeline under the elastic force action of the elastic support assemblies. According to the invention, the magnetic circuit modules of the submarine pipeline magnetic leakage internal detection device can always adhere to the inner wall of the submarine pipeline under the elastic force action of the elastic support assemblies, when the internal diameter of the pipeline is changed, the shape of the detection device can be changed in a self-adapting manner, and therefore the magnetic circuit modules and the submarine pipeline can always achieve a magnetic circuit closed loop, and the detection device is without missing points during the whole detection process, and the detection precision is greatly improved.
