Problems solved by technology

[0003] At present, most ocean monitoring uses manual seawater sampling and laboratory analysis methods. A few common buoy-type sampling methods for ocean monitoring use a single rope suspension, which cannot control the monitoring and sampling of seawater at different heights. At the same time, the overall device The sampler and the buoy are separated, it is not easy to store and transport, and there are certain disadvantages

Embodiment 1

[0023] Embodiment 1 is used for the buoy type sampling device of marine monitoring

[0024] Such as Figure 1~3 As shown, the buoy type sampling device used for ocean monitoring in this embodiment includes a floating shell 1, a signal column 2 and a sampling tube 12, the top of the floating shell 1 is fixed to the bottom of the signal column 2, and the side wall of the signal column 2 The fastening frame 3 is fixedly connected to the top of the floating shell 1 . The top of the floating shell 1 is fixedly connected with a solar panel 4, and the cavity of the floating shell 1 is provided with a winding rod 6 and a first driving mechanism for driving the winding rod 6 to rotate. The first driving mechanism in this embodiment is The first motor 7. The bottom of the inner side wall of the cavity is fixedly connected with a fixed block 5, and one end of the winding rod 6 is connected to the fixed block 5 in rotation, and the other end of the winding rod 6 is fixedly connected wit...

Embodiment 2

[0034] Embodiment 2 sampling method

[0035] This embodiment provides a method for sampling based on the buoy sampling device in Embodiment 1, which specifically includes the following steps:

[0036] 1) Assembly and placement of the sampling device

[0037] Place the six sampling chambers in the sampling block 24, assemble the sampling tube 12, combine the sampling tube 12 with the floating shell 1, etc., and then place the buoy type sampling device in the water area to be sampled.

[0038] 2) First sampling

[0039] The first motor 7 is controlled to start, and the sampling tube 12 is lowered to a preset height for sampling through the two wire ropes 9 wound on the winding rod 6 .

[0040] Seawater flows into the sampling pipe 12 along the water inlet 30, rotates through the second motor 14, drives the slider 19 to push the seawater in the sampling pipe 12, and utilizes the push rod 20 to push the piston plate 27 into the sampling chamber 25, so that One end of the connec...

Abstract

The invention discloses a buoy type sampling device for ocean monitoring. The device comprises a floating shell, a sampling pipe and a rope for connecting the floating shell and the sampling pipe, a cavity is arranged in the floating shell, a winding rod and a first driving mechanism for driving the winding rod to rotate are arranged in the cavity, and the first driving mechanism is used for driving the winding rod to rotate. One end of the rope is wound on the winding rod, the other end of the rope is connected with the sampling pipe, and a water inlet is formed in the wall of the sampling pipe. According to the buoy type sampling device for ocean monitoring, the rope wound on the winding rod is fixedly connected with the sampling pipe, so that the sampling pipe can be placed at differentheights of seawater for sampling during sampling, the sampling pipe is collected after sampling is completed, and the whole device is convenient to store and transport.

Description

technical field [0001] The invention belongs to the technical field of seawater sampling methods, and in particular relates to a buoy-type sampling device for ocean monitoring and a seawater sampling method using the buoy-type sampling device. Background technique [0002] In marine monitoring, it is often necessary to collect water samples for monitoring sea water bodies, and analyze and measure them to obtain basic data on water body pollution. The water samples for analysis should be representative and able to reflect the chemical composition and characteristics of the water body. The sampling method, location, time, frequency, etc. are all determined according to the characteristics of the water body and the purpose of analysis. [0003] At present, most ocean monitoring uses manual seawater sampling and laboratory analysis methods. A few common buoy-type sampling methods for ocean monitoring use a single rope suspension, which cannot control the monitoring and sampling ...
