Embodiment Construction

[0021] The present invention will be further described below in conjunction with accompanying drawing, protection scope of the present invention is not limited to the following:

[0022] Such as Figure 1~2 As shown, a anchor chain sensor fixing fixture for offshore platforms based on screw fastening, which includes an inwardly inclined inner hexagon locking screw (1), and an inner inward hexagon ensures that the ROV can insert the hexagonal wrench into the screw rod in a wide range; Nylon self-locking nut (2); disc-shaped stop spring (3) arranged on the inner hexagon locking screw (1), the spring is compressed after the screw is tightened to generate strain elastic force to prevent the screw from loosening; fixture frame (4) , the fixture frame is made of a stamped hollow corrugated plate (17), and the interior is a corrugated hollow structure, which reduces the overall mass while ensuring the strength; the reinforcing rib (5) welded to the deformable part of the fixture fram...

Abstract

The invention discloses an anchor chain sensor fixing clamp for an offshore platform based on screw fastening, which comprises inward inclining inner hexangular locking screw, a nylon self-locking nut, a disc retaining spring, a clamp frame, a screw-clamping plate connecting bearing, V-shaped guide clamping plate, a guide rail, sensor fixing hoops, a U-shaped positioning clamping plate and a positioning assistant magnet, and is characterized in that the screw-clamping plate connecting bearing is connected with the screw and the V-shaped guide clamping plate, the clamp frame is composed of a press-molding hollow corrugated sheet material, and the positioning assistant magnet is embedded in a groove at the inner side of the clamp frame. The advantages are that the anchor chain sensor fixing clamp is simple in structure and convenient to be assembled and disassembled, and assembly and disassembly of the whole clamp can be completed by an ROV remotely; the anchor chain sensor fixing clamp is accurate in positioning and tight and reliable in fixation, can ensure that a sensor and an anchor chain have no relative motion and relative acceleration therebetween and ensures normal and effective operations of the sensor.

Description

technical field [0001] The invention relates to a fixture for fixing a anchor chain monitoring sensor on an offshore platform that is installed and disassembled underwater by an ROV. The fixture effectively fixes the anchor chain monitoring sensor on a target anchor chain in deep water through the ROV. Background technique [0002] The mooring positioning system is an important part of the offshore platform. When the offshore platform is fixed in the operating sea area through anchor chain mooring or anchor chain mooring hybrid positioning, the anchor chain mooring system needs to ensure the normal operating conditions of the platform and the safety of the platform. working conditions. The deep sea environment is complex and special, and it is difficult to predict. The movement of the anchor chain in the anchor chain mooring system is related to the safety and reliability of the entire system. In actual production, it is necessary to ensure the safety control of the mooring ...
