Embodiment Construction

[0030] In order to clearly illustrate the technical characteristics of this solution, the following will describe this solution through specific implementation modes and in conjunction with the accompanying drawings.

[0031] Such as figure 1 As shown, a seawater sampling device based on different depths of the present invention needs to be used with a marine scientific research ship. The marine scientific research ship is equipped with a special winch and a CTD deck unit, and the CTD deck unit is connected to the computer control terminal through a communication line. The special winch is used to lower and recover the seawater sampling device, and the CTD deck unit is used to receive and convert the electrical signal from the underwater sensor and transmit it to the computer control terminal.

[0032] Such as Figure 2 to Figure 6 As shown, the seawater sampling device based on different depths includes a cabin body, an upper hatch cover 1 is provided at the upper end of the...

Abstract

The invention discloses a seawater sampling device based on different depths, which comprises a cabin body, an upper hatch cover is arranged on the upper end of the cabin body, a partition is arranged in the cabin body, and the partition board divides the inside of the cabin body into an equipment cabin and a power supply cabin; the equipment cabin Including the first cabin, the second cabin and the third cabin, the first cabin and the second cabin are closed cabins, the third cabin is an open cabin, and a communication unit is installed on the top of the first cabin; A seawater sampling device is installed in the first cabin, a biological sampler is installed in the second cabin, and a thermosalinity depth profiler and an ocean current profiler are installed in the third cabin. It solves the problem that the current seawater collector has single function and the sampling bottle is easy to be damaged and aged. The invention adopts the structure design of the cabin, and the water collection bottle is arranged in the cabin. The water collection bottle does not need to use high-strength pressure-resistant materials. The equipment has a long service life, small volume, reasonable structure, and is easy to put in. detection in one function.

Description

technical field [0001] The invention belongs to the technical field of ocean detection, and in particular relates to a seawater sampling device based on different depths. Background technique [0002] Marine environmental monitoring is an important part of marine ecological environment protection, and the analysis of seawater composition is an important content of marine environmental monitoring. Due to light, pressure and other reasons, the composition and content of plankton and inorganic substances in seawater at different depths are different, so it is necessary to collect seawater at different depths for experimental analysis. [0003] In order to achieve the above purpose, the commonly used seawater collection method is to use the seawater collector to be lowered into the sea for collection. The patent application number is 2016103152823, which discloses an intelligent multi-depth seawater collector, including a mounting bracket, a seawater collector and a sensor contr...
