Problems solved by technology

Although the winch has achieved the required functions and technical performance, the whole machine has the problems of large volume, heavy weight and many operation steps.
Moreover, the winding machine that winds the wire rope back to the probe bobbin uses an AC speed-regulating motor. Due to the imperfect tension control function during winding, there is a problem that the winding quality is not high, which affects the success rate of putting the probe into the predetermined depth.

Embodiment Construction

[0038] It should be noted that, in the case of no conflict, the embodiments of the present invention and the features in the embodiments can be combined with each other.

[0039] The overall design principle of the present invention is as follows: from the perspective of the needs of marine scientific research, the profile data can better reflect the distribution of ocean thermohaline by lowering the instrument vertically at fixed points. If the vertical descending movement of the probe is realized when the ship is sailing, it is necessary to adopt the method of double-ended setting-out. In this way, the descending of the probe and the movement of the ship can be almost completely decoupled, that is, its descending speed is independent of the movement of the ship. like figure 1 shown.

[0040] The UCTD-marine dynamic parameter towed profile measurement system proposed by the present invention is composed of a portable special winch 1, a fast winding machine, a wire rope 2, a ...

Abstract

The invention discloses an underway conductivity temperature depth measuring system which comprises a winch, a winding machine, a recovery cotton rope, a UCTD (underway conductivity temperature depth)probe and a deck terminal computer. The winch is used for rapidly placing and recovering the probe, the winding machine is used for rapidly winding on a reel after the probe is recovered, the probe carries a self-contained CTD (conductivity temperature depth) instrument and is used for measuring CTD data of a marine profile, and the terminal computer collects probe data after the probe is recovered to a deck. The requirements of a research vessel for rapid installation, convenience in use, stability and reliability are met, and reliability, environmental adaptability and maintainability of UCTD equipment are improved.

Description

technical field [0001] The invention relates to the technical field of seawater detection, in particular to a towed profile measurement system for marine dynamic parameters. Background technique [0002] From the perspective of the needs of marine scientific research, the acquisition of profile data can better reflect the distribution of ocean thermohaloclines, but the cost of ocean profile surveys is high. Therefore, in recent years, the marine dynamic parameter towed profile measurement system ( UCTD) research. [0003] At present, the UCTD prototype developed in China, the winch adopts the principle of frequency conversion and speed regulation, and realizes the function of quickly launching and recovering the probe. When recovering, it adopts stepless speed change, the brake adopts belt brake, and the power transmission between the AC motor and the reel adopts a single-plate clutch. . Although the winch has achieved the required functions and technical performance, the ...
