[0026] SeeFigures 1 - 3 , a sounding weight with a water sample collection function, comprising the body of the sounding weight and a scale 1; the body of the sounding weight is divided into upper and lower parts, the lower part is a hammer body 9, and the upper part is a cavity structure with the function of collecting and storing ballast water. The side wall of the connecting part between the cavity structure and the hammer body 9 is a hollow structure, and the hollow part forms a water inlet 8; a movable water inlet piece 5 is rotatably connected to the inner wall of the cavity structure above the water inlet 8; the upper part of the cavity structure has a vent hole 3; the scale 1 is fixedly connected to the top of the body of the sounding weight. This solution adopts a lower sounding weight body, a middle water inlet, an upper water sample storage area, a vent hole is provided at the top, a movable water inlet piece is provided at the connection between the upper and middle parts, and a hollow water inlet structure form is adopted.

[0027] In this embodiment, referring to Figures 1 - 2 , a ring-shaped movable water inlet piece base 7 is fixedly arranged on the inner wall of the cavity structure below the movable water inlet piece 5, which is used to carry and limit the movable water inlet piece base 7 and keep it horizontal.

[0028] In this embodiment, referring to Figure 1 , a movable water inlet piece seal ring 6 is provided on the movable water inlet piece base 7. The water sample storage seal adopts the form of a movable water inlet piece plus a base seal ring.

[0029] In this embodiment, referring to Figure 1 , the hammer body 9 is a brass or stainless steel solid.

[0030] In this embodiment, referring to Figure 1 , the movable water inlet piece 5 is made of silica gel.

[0031] In this embodiment, referring to Figure 1 , the upper part of the cavity structure is a water sample storage area 11.

[0032] In this embodiment, referring to Figure 1 , the volume of the water sample storage area 11 is larger than that of the hammer body 9.

[0035] Based on the sounding weight of the sounding rod commonly used at present, the sounding weight of the present utility model is divided into two parts. The lower body is still a conventional brass or stainless steel solid, and the upper body is a cavity structure capable of collecting and storing ballast water. There is a hollow structure between the cavity structure and the solid of the lower body. There is a ventilation hole above the cavity structure, and the controllable water inlet piece 5 below is made of silica gel. When the sounding weight enters the ballast tank along the sounding pipe, the ballast water enters the hollow water inlet area. Due to the action of water pressure, the movable water inlet piece 5 deflects along the movable center, and the ballast water enters the water sample storage area 11. When the sounding weight is pulled, under the action of the downward gravity of the ballast water, the movable water inlet piece 5 deflects downward to restore its original state, and contacts the cavity structure through the sealing ring 6 below the water inlet piece 5 to seal the lower part of the cavity structure. After the sounding weight is taken out of the sounding pipe, the collected ballast water can be obtained through the ventilation hole 3 above.
