Device for monitoring tension force of mooring anchor chain

Abstract

The invention relates to a device for monitoring the tension force of a mooring anchor chain, and the device comprises a watertight pressure bearing housing with a cavity. The interior of the cavity of the watertight pressure bearing housing is provided with a unidirectional full-bridge strain sensor and a sulfuration die metal housing. A signal collection communication circuit is disposed in thesulfuration die metal housing, and the interior of the sulfuration die metal housing is provided with a polyurethane resin adhesive encapsulation part. The unidirectional full-bridge strain sensor isconnected with the signal collection communication circuit through a signal line, and the signal collection communication circuit is connected with one end of a watertight connector through a signal line, wherein the other end of the watertight connector stretches out of the watertight pressure bearing housing to be connected with a watertight cable. The device is simple in structure, is convenient to use, can achieve the real-time monitoring of an internal tension force of the anchor chain, enables a person to know the tension changes of the anchor chain and to achieve the estimation of the remaining service life of the anchor chain, and also enables the person to take measures to avoid the dangers when the tension of the anchor chain is abnormal.

Description

technical field [0001] The invention relates to the field of stress monitoring of deep sea structures, in particular to a mooring anchor chain tension monitoring device. Background technique [0002] The marine floating platform is fixed in a certain sea area through a mooring system, so as to prevent the platform from drifting with the waves and ensure the normal operation of the platform. The floating platform mooring system usually consists of multiple anchor chains, and each anchor chain is generally composed of a grabbing anchor, an anchor cable, a seabed link, an inter-chain cable, a connecting shackle and a platform link. The main function of the mooring system is to control the horizontal movement of the floating platform under the action of environmental loads through the stiffness (or quality) of the anchor chain itself, so as to ensure the normal operation and survival of the floating platform. When designing the anchor chain of the mooring system, according to t...

Problems solved by technology

Since the mooring anchor chain has been working in a high-tension marine environment for a long time, its corrosion and fractures occur from time to time. In order to avoid the breakage of the anchor chain, it is necessary to monitor the tension of the mooring system in real time. The existing monitoring devices have complex implementation processes and cost Disadvantages such as high and poor versatility
