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...

The invention discloses a seawater sampling device based on different depths. The device comprises a cabin body, an upper cabin cover is arranged at the upper end of the cabin body, a partition plateis arranged in the cabin body, and the interior of the cabin body is divided into an equipment cabin and a power supply cabin by the partition plate; the equipment cabin comprises a first cabin body,a second cabin body and a third cabin body, the first cabin body and the second cabin body are closed cabin bodies, the third cabin body is an open cabin body, and a communication unit is installed atthe top of the first cabin body; a seawater sampling device is arranged in the first cabin body, a biological sampler is arranged in the second cabin body, and a temperature-salinity-depth section plotter and an ocean current section plotter are arranged in the third cabin body. The problems that an existing seawater collector is single in function, and a sampling bottle is prone to damage and aging are solved. According to the invention, the structural design of the cabin body is adopted, a water sampling bottle is arranged in the cabin body, the water sampling bottle does not need to use ahigh-strength pressure-resistant material, the equipment is long in service life, small in size, reasonable in structure and convenient to put, and meanwhile, the function of integrating water sampling, biological sampling and detection is realized.
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...
