Detailed Description

The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic drawings and illustrate the basic structure of the present invention only in a schematic manner, and thus show only the components related to the present invention.

Fig. 1 is a schematic structural diagram of the present invention; fig. 2 is a sectional view of the water container of the present invention.

The utility model provides a water sampling device, includes flourishing water receptacle 1, the cap body 2, connecting piece 3, fragment 4, apron 5, floater 6, balancing weight 7, the open end of flourishing water receptacle 1 links together through connecting piece 3 and cap body 2 detachable, and connecting piece 3 internal fixation is used for sealing 1 open-ended fragment 4 of flourishing water receptacle, is equipped with the water inlet on the cap body 2, and swing joint has apron 5 in the flourishing

water receptacle

1, and 5 bottoms of apron are connected with

floater

6, and 1 bottoms of flourishing water receptacle is connected with balancing weight 7.

The connecting piece 3 is a ring-shaped piece, the inner wall of the connecting piece 3 is provided with threads, the outer wall of the port of the water container 1 is provided with threads, the outer wall of the bottom of the cap body 2 is provided with threads, and the bottom of the cap body 2 and the port of the water container 1 are respectively in threaded connection with the connecting piece 3.

One end of the cover plate 5 is movably connected with one end of the connecting rod 8, and the other end of the connecting rod 8 is movably connected in the water container 1.

The cap body 2 is a conical cap.

A filter screen is arranged at the water inlet of the cap body 2.

The water container 1 is provided with a hook 9, and the counterweight block 7 is provided with a hanging lug 10 for passing through the hook 9.

The water container 1 consists of a container body 11 and a straight pipe 12, wherein the opening of the container body 11 is in threaded connection with the straight pipe 12, and the straight pipe 12 is in threaded connection with the connecting piece 3.

And (3) calculating the external water pressure intensity of the target depth according to the water density and the water type of the sampling position by combining the attached drawings 1 and 2, and selecting the corresponding prefabricated fragments 4 to be installed in the sampling device. The sampling device is placed in water, when the pressure of the external water minus the pressure value of the atmospheric pressure in the inner cavity of the water container 1 is greater than the rupture threshold value of the prefabricated fragment 4, the fragment 4 ruptures, and the sample water entering from the water inlet on the cap body 2 enters the inner cavity of the water container 1.
