Description

A put in and retrieve protector for CTD sea water sampling equipment

Technical Field

The invention relates to the technical field of an auxiliary device for operation of an ocean thermohaline depth gauge, in particular to a throwing and recovering protection device for CTD seawater sampling equipment.

Background

The CTD system is a Temperature and Depth (Depth) measuring system, generally called a warm and salt Depth system, and is used for measuring three basic physical parameters of a water body, namely, the Conductivity, the Temperature and the Depth. Sea water temperature and salinity observation and sea water temperature profile and salinity profile observation are important contents in marine hydrological environment investigation. According to the three parameters, other physical parameters such as sound velocity and the like can be calculated. Is necessary equipment for investigating oceans and other water bodies. Mainly by probe in water and record display and connecting cable constitute: the probe is composed of a thermosensitive element, a pressure-sensitive element and the like, is arranged on the bracket together with the inverted water sampler, and can be thrown to different depths; the recording display can receive, process, record and display various information data transmitted from the probe in the seawater through the armored cable, and can also play the function of a manipulator of the whole set of equipment. The device can measure the temperature, salinity, oxygen content, sound velocity, conductivity and pressure of seawater in different water layers or depths of the ocean, and is used for researching the physical and chemical properties, the water layer structure and the water mass motion condition of the seawater.

The application of the deep measuring apparatu of warm salt is also very many, for example CN 204999492U discloses a deep appearance of warm salt observation support with protection device, belongs to a deep appearance operation auxiliary device of warm salt, including the support body, the top of support body is equipped with rings, and the below of support body still is equipped with the balancing weight, the side movable mounting of support body has at least one fixation clamp, the top of support body still is equipped with the protection rope. Fix the inside at the support body with the deep appearance of warm salt through fixation clamp and protection rope on support body upper portion, put into under water with support body and inside deep appearance of warm salt through the balancing weight of support body below in the lump, because the deep appearance of warm salt passes through fixation clamp and protection rope and this body coupling of support as an organic whole, and then stability when effectively promoting to transfer, and can transfer the seabed perpendicularly to make the deep appearance of warm salt can acquire comparatively accurate data. The application forms comprise the use with ships, the installation in a fixed-point marine observation system, the installation on a marine mobile observation platform and the like. The device is used with a ship: when the survey ship reaches an observation point, the temperature and salinity depth measuring instrument is moved to the sea surface from the deck through a marine winch, and then is sent to a certain depth underwater from the sea surface, and meanwhile, the temperature and salinity data at different depths are measured. The device is installed in a fixed-point marine observation system for use: and hanging the thermohaline depth measuring instrument on a mooring rope of an anchoring observation system, and hanging the thermohaline depth measuring instrument according to different depths in layers. Above-mentioned patent can and then effectively promote stability and security when transferring, and can transfer the seabed perpendicularly.

In general, when marine hydrology is investigated using a large marine survey vessel or a scientific research vessel, a thermodepth gauge is thrown and recovered by a winch provided on the vessel. However, if the thermohaline depth measuring instrument recovered to the scientific investigation ship is placed on a deck or in a laboratory, the ship body can inevitably and irregularly rock due to the influence of wind waves and water flow on the sea, the worn thermohaline depth measuring instrument is easy to collide and slide, certain influence can be caused on the thermohaline depth measuring instrument on the scientific investigation ship, and once the instrument components are damaged, the instrument is expensive, data loss can be caused, and great loss is caused.
