Embodiment Construction

[0014] The present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.

[0015] figure 1 , 2 , 3 shows a structural view of an ROV underwater rapid installation and replacement device for anchor chain sensors on a deepwater platform. In the figure, the sensor installation and fixing device of the deepwater platform anchor chain includes an upper frame 1, a lower frame 2, a sensor load-bearing cylinder 3, a load-bearing cylinder seat 4 and a locking mechanism. The upper frame 1 and the lower frame 2 are fixed on the anchor chain by a locking mechanism. Above, the sensor load-bearing cylinder 3 is fixed on the upper frame 1 through the load-bearing cylinder seat 4 and the locking mechanism; the upper frame 1 and the lower frame 2 adopt a hollow rectangular cross-section structure, and the sensor load-bearing cylinder 3 adopts a cylinder with two handles Shaped structure, the handle of the cylinder is convenient for underwa...

Abstract

The invention provides a device for a remotely-operated vehicle (ROV) to quickly mount and replace a sensor on a deepwater platform anchor chain underwater and belongs to ocean platform equipment. By adopting the device, unmanned mounting and replacing of the sensor on the deepwater platform anchor chain can be achieved through the ROV. The device comprises an upper frame, a lower frame, a sensor bearing and positioning cylinder and a locking mechanism, wherein the upper frame and the lower frame are fixed to the anchor chain through the locking mechanism; the sensor bearing and positioning cylinder is matched with the upper frame in a clamped mode and fixed to the upper frame; the lower frame is of a hollow structure with a rectangular cross section; the upper frame is of a structure formed by welding a bent steel plate and a cylinder together; the sensor bearing and positioning cylinder is of a cylinder structure provided with a handle matched with an underwater robot arm, and the cylinder seals up the sensor and can resist external pressure. The sensor fixing device is simple in structure and brings convenience to the ROV to quickly mount and replace the self-contained sensor underwater, and the mounting accuracy and reliability are guaranteed.

Description

technical field [0001] The invention relates to a deep-sea platform anchor chain sensor ROV underwater rapid installation and replacement device, which belongs to an ocean platform equipment and realizes unmanned installation and replacement of sensors on the deep-sea platform anchor chain by an underwater robot ROV. Background technique [0002] The mooring system is the main fixing method for offshore floating production and drilling platforms. Environmental loads such as waves, currents, and typhoons acting on the floating body are mainly borne by the mooring system. Floating platforms in the Gulf of Mexico and the South my country Sea have experienced major accidents in which mooring breaks and floating bodies shifted due to typhoon action, resulting in breakage of oil production pipelines. Therefore, in order to obtain real-time information of the mooring system and ensure the normal operation of the mooring system, on-site monitoring of the mooring system is urgently ...
