Description
Technical Field
The utility model belongs to ocean resource investigation field specifically relates to a height measuring and calculating device is transferred perpendicularly to reality under loop wheel machine wire rope tilt state.
Background
In scientific investigation, a thermohaline depth detector (CTD) is often used for water collection and data collection; the CTD is divided into an autolysis type and a direct-reading type, the direct-reading type can read data such as water depth in real time, but the direct-reading type CTD cannot move after being installed because a steel wire rope and a data cable are integrated. Autolysis formula CTD need not take the cable to launch, consequently can use on different boats and ships as required, but need set for in advance according to the depth of water and adopt the water depth, influenced by the ocean current in the in-service use process, CTD is put in-process wire rope under and has the slope of certain angle, this length that has just led to actual wire rope to transfer is greater than the actual depth of water, rivers are big more, the deep gap is big more than the depth of water, consequently the degree of depth that can't accurate judgement actually transferred, cause the accident of touchdown easily. Enough safety distance needs to be reserved in the CTD setting, so that water and hydrological information of a lower layer cannot be acquired.
Disclosure of Invention
The invention aims to provide a device for measuring and calculating the actual vertical lowering height of a crane steel wire rope in an inclined state, which solves the problem of actual lowering deviation caused by ocean current and provides relatively accurate sinking depth of the crane steel wire rope.
