Sampling device for ocean monitoring of quality of seawater at different depths

Abstract

The invention discloses a sampling device for ocean monitoring of the quality of seawater at different depths. The device includes a base, wherein bottom portions of four side surfaces of the base areequipped with mounting tabs, a top end of the base is connected with a rotation seat, and one end of the rotation seat is connected with a mounting plate. The device is advantaged in that the structure is scientific and reasonable and is safe and convenient to use, when a sampling bucket is lowered, all solenoid valves are opened by a control switch, the seawater passes through a seawater sampling bin, the seawater at the sampling position can be sampled; when the sampling bucket is lowered, the corresponding solenoid valves are closed by the control switch to sample at different depth positions, a rotating handle is taken out by opening a storage cover, one end of the rotating handle is mounted on a hexagonal rotating block, the rotating handle is turned to drive the hexagonal rotating block and a rotating shaft to rotate, a cable storage roller can be driven to rotate, when a driving motor fails, the cable storage roller can be manually driven to rotate, and the sampling bucket is pulled out of the sea.

Description

technical field [0001] The invention relates to the technical field of seawater sampling, in particular to a seawater quality sampling device with different depths for ocean monitoring. Background technique [0002] The surface of the earth is divided into vast waters connected to each other by the major continents called oceans. Its total area is about 360 million square kilometers, accounting for about 71% of the earth's surface area. The average water depth is about 3795 meters. The ocean contains more than 1.35 billion Tens of thousands of cubic kilometers of water account for about 97% of the total water on the earth, but only 2% are available for human consumption. The four main oceans on the earth are the Pacific Ocean, the Atlantic Ocean, the Indian Ocean, and the Arctic Ocean. Most of them are land and seabed topographic lines As a boundary, the deep sea area is rich in oil, natural gas and other oil and gas resources. It is the largest potential strategic resource ...

Problems solved by technology

[0004] The present invention provides a technical solution, which can effectively solve the problem that seawater of different depths cannot be sampled at one time, and the sampler needs to be put into the sea for sampling for many times, the sampling efficiency is low, and the loss of the sampler is used. major problem
