Throwing and recycling protection device for CTD seawater sampling equipment

Abstract

The invention discloses a throwing and recycling protection device for CTD seawater sampling equipment. The throwing and recycling protection device comprises a winch provided with a hoisting beam. The hoisting beam comprises a fixed beam and a movable beam. A steel wire rope is released through the winch and penetrates the fixed beam and the movable beam. The steel wire rope further comprises a drive mechanism for driving the movable beam to telescopically move along the fixed beam. The tail end of the movable beam is provided with a rotation wheel for supporting the steel wire rope and a locking mechanism. The locking mechanism comprises a protection head connected to the tail end of the movable beam, an upper locking plate and a lower locking plate, wherein a damping component is arranged between the upper locking plate and the lower locking plate. The lower locking plate is provided with an electromagnet used for fixing the hoisted and recycled CTD seawater sampling equipment to the lower locking plate. After recycling, the problems that traditionally, the CTD seawater sampling equipment is placed on a ship, slides and suffers from collisions, and consequently the CTD seawatersampling equipment is damaged is solved, and the problem about storage of the CTD seawater sampling equipment in the field is solved.

Description

technical field [0001] The invention relates to the technical field of operation auxiliary devices for ocean temperature, salinity and depth instruments, in particular to a throwing and recovery protection device for CTD seawater sampling equipment. Background technique [0002] The CTD system is the Conductivity, Temperature, Depth (Conductivity, Temperature, Depth) measurement system, generally known as the temperature-salinity-depth system, which is used to measure the three basic water body physical parameters of conductivity, temperature and depth. Seawater temperature, salinity observation, seawater temperature profile and salinity profile observation are important contents in marine hydrological environment investigation. According to these three parameters, various other physical parameters, such as the speed of sound, can also be calculated. It is a necessary equipment for marine and other water surveys. It is mainly composed of underwater probes, recording displa...

Problems solved by technology

However, if the thermosalt depth measuring instrument recovered on the scientific research ship is placed on the deck or in the laboratory, due to the influence of wind, waves and currents on the ship at sea, the ship will inevitably shake irregularly. The depth measuring instrument is prone to collision and slippage, which will have a certain impact on the temperature, salinity and depth measuring instrument on the scientific research ship. Once the instrument components are damaged, not only the instrument is expensive, but also the data will be lost, causing heavy losses
