Problems solved by technology

The instrument used to measure the tension of the cable is a tension gauge. At present, there are crane tension gauges with luminous digital tube display at home and abroad, or liquid crystal display tension gauges with wireless transmission function, but for the tension that can be recorded for a long time in seawater environment Count, there is no corresponding product

Abstract

The invention relates to a real-time automatic recording type tension gauge for measuring the tension of underwater cables, which comprises a device for automatically recording data. A seal housing is arranged in the device. A cable used as a signal input end of the device for automatically recording data is connected with four strain discs in a through hole of an elastic strain transducer, and the device for automatically recording data is fixed on a supporting pillar through a screw bolt and a rubber block; and the supporting pillar is fixed on the elastic strain transducer through a screw hole. The real-time automatic recording type tension gauge has the advantages of small volume and light weight and can effectively measure and record the tension of underwater cables for more than 15 days. The recorded data is converted by a single chip computer and is stored in an SD card, the data can be read and a data curve can be displayed in the WinXP environment of a personal computer (PC).The invention provides an important measuring tool for researching the tension characteristics of cables of oceanic facilities such as culture cages, and the like.

Description

technical field [0001] The invention relates to a real-time automatic recording tension meter used for measuring the tension of underwater cables. Background technique [0002] Deep-sea aquaculture cages and other engineering facilities are placed in sea areas with strong winds, high waves, and rapid currents all year round. As an engineering carrier for fish farming, cage facilities will withstand huge environmental loads under complex sea conditions, especially disastrous climate conditions. , posing a great threat to facilities and farmed fish. Cage culture requires that the cage system (including rigid cage frame structure, net clothing box body, mooring system and other auxiliary structures) has sufficient strength to resist the attack of strong wind and waves, prevent fish from escaping, and avoid causing huge economic losses. loss. The frame system and netting system of aquaculture cages are anchored in specific sea areas by cables. Researching and mastering the for...
