Background technique

Seawater sampling is the most routine survey content of marine related majors, and analyzing various indicators in seawater is an important way to research and develop the ocean. Usually, we need to collect seawater from different water layers. However, the mass of the ordinary water collector itself is very small, and it is easily affected by ocean currents, which makes it impossible for the water collector to sink vertically to a certain depth, which brings certain errors to the experiment. The researchers had to find another heavy object to tie to the water collector, but the heavy object was difficult to fix, and the probability of slipping was extremely high. Moreover, different water depths have different requirements on the quality of water collectors, which brings a lot of inconvenience to the experiment. However, the conventional rose-type water harvester needs to be equipped with a winch and has high requirements on the conditions of the ship.

Keep the water collection device 1 in a vertically falling state to improve the accuracy of sample water collection; when the water collection device reaches the specified depth, the control box 2 controls the valve 11 and the water inlet and outlet valves to close, the electric push rod 15 stops working, and the two-way push rod 103 shrinks, so that the tension rope 102 pulls the upper cover 6 and the lower cover 7 to open it, and the sample water enters the water collection device 1. After the water collection is completed, the control box 2 controls the extension of the two-way push rod 103, so that the tension rope 102 loses its tension. , the upper cover 6 and the lower cover 7 are re-closed due to the recovery of the rubber rope 101 and the effect of water pressure; after the water collection is completed, the rope is recovered, the water collection device rises, and the control box 2 controls the water inlet and outlet valves to open during the rise , the gas generator 14 gradually releases the gas, and the electric push rod 15 pushes the rubber plug to move downward, so that the water tank 3 gradually discharges the water body, reduces the quality, and facilitates recovery; the water collection device rises to the water surface to complete water collection; The pipe clamp 9 clamped by the water outlet pipe 8 takes out the sample water body.

The conventional technology in this embodiment is the prior art known to those skilled in the art, and will not be described in detail here.

Example 4:

Using the water collection device and water collection method described in Example 2, compared with the existing card cover type water collection device, purchased from Beijing Prime Instrument Co., Ltd. for comparative experiments, the water collection device in Example 2 was set as the experimental group , the existing card cover type water collector is the control group.

The experiment took place in the waters from Zhoushan Dinghai to Panzhi Island. The target depth of sampling water was 65m. During the experiment, the waves were suitable and the seawater flow in the waters was suitable. The experiment was divided into two groups. Horizontal line with a scale. In each experiment, two sets of water collectors are submerged in the water at the same time. The two sets of water collectors are lowered close to each other, and the seawater flow conditions are similar. On the horizontal plane, both groups of water collecting devices use ropes, and three groups of experiments are carried out, each group carries out 10 water collecting operations, and the average horizontal offset is calculated, which is recorded in the table below.

It can be obtained from the data in the above table that the horizontal offset of the water collector of the present invention is much smaller than that of the existing water collectors. High degree, with greater application prospects.

The water storage space 13 of the water tank 3 can store water body not only limited to 5～10kg, also should comprise 5kg or 5.1kg or 5.2kg or 5.3kg or 5.4kg...or 9.9kg or 10kg.

The central angle of the arc of the arc edge groove 124 is not limited to 23-31°, but also includes 23° or 23.1° or 23.2° or 23.3° or 23.4°...or 30.9° or 31°.

The conventional technology in this embodiment is the prior art known to those skilled in the art, and will not be described in detail here.

The above embodiments are only used to illustrate the present invention, but not to limit the present invention. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of the present invention. Therefore, all equivalent technical solutions also belong to the category of the present invention, and the scope of patent protection of the present invention should be defined by the claims.
