Sampling through sounding pipes faces the problem that ballast water cannot be collected through narrow sounding pipes. Sampling through watertight manholes requires removing the screws of the manhole cover one by one, which is a complicated process and has poor safety. Ballast water sampling and collection through sounding pipes is impossible due to the narrowness of sounding pipes. Summary of the invention

DETAILED DESCRIPTION

[0024] The present invention is further described below in conjunction with the accompanying drawings and specific embodiments.

[0026] See also Figure 1-3A sounding hammer with a water sample collection function includes a sounding hammer body and a scale 1; the sounding hammer body is divided into two 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 connection part between the cavity structure and the hammer body 9 is a hollow structure, and a water inlet hole 8 is formed in the hollow part; the cavity structure is rotatably connected to a movable water inlet sheet 5 on the inner wall above the water inlet hole 8; the upper part of the cavity structure has an air vent 3; the scale 1 is fixedly connected to the top of the sounding hammer body. This scheme adopts a lower sounding hammer body, a middle water inlet hole, an upper water sample storage area, an air vent structure is arranged on the top, a movable water inlet sheet is arranged at the connection between the upper and middle parts, and a hollow water inlet structure is adopted.

[0027] In this embodiment, see Figure 1-2 An annular movable water inlet plate base 7 is fixedly arranged on the inner wall of the cavity structure at the lower part of the movable water inlet plate 5, which is used to support and limit the movable water inlet plate base 7 and keep it level.

[0028] In this embodiment, see Figure 1 A movable water inlet sheet sealing ring 6 is arranged on the movable water inlet sheet base 7. The water sample storage seal adopts the form of a movable water inlet sheet plus a base sealing ring.

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

[0030] In this embodiment, see Figure 1 The movable water inlet sheet 5 is made of silicone material.

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

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

[0033] In this embodiment, see Figure 1 A sounding hammer hanging handle 2 is fixedly provided on the upper part of the body of the sounding hammer, and the scale 1 is fixedly connected to the body of the sounding hammer through the sounding hammer hanging handle 2.

[0034] In this embodiment, combined with Figure 2 and Figure 3 It can be seen that the body of the sounding hammer is in a cylindrical shape.

[0035] The present invention is based on the sounding hammer of the currently commonly used sounding scale, and divides the sounding hammer into two parts. The lower body is still a conventional brass or stainless steel entity, and the upper body is a cavity structure with the function of collecting and storing ballast water. The cavity structure and the entity of the lower body are hollow structures, and there are air holes on the top of the cavity structure. The controllable water inlet sheet 5 below is made of silica gel. When the sounding hammer enters the ballast tank along the sounding pipe, the ballast water enters the hollow water inlet area. Due to the water pressure, the movable water inlet sheet 5 deflects along the movable center, and the ballast water enters the water sample storage area 11. When the sounding hammer is pulled, the movable water inlet sheet 5 deflects downward to restore the original state under the downward gravity of the ballast water, and the sealing ring 6 below the water inlet sheet 5 contacts the cavity structure to seal the bottom of the cavity structure. After the sounding hammer is taken out of the sounding pipe, the collected ballast water can be obtained through the air holes 3 above.

[0036] The key points of the structure of this embodiment include the following:

[0037] It adopts a sounding hammer at the bottom, a water inlet in the middle, a water sample storage area at the top, and a vent hole at the top;

[0038] A movable water inlet piece is provided at the connection between the upper part and the middle part;

[0039] Adopt hollow water inlet structure;

[0040] The water sample storage seal adopts the form of a movable water inlet piece and a base sealing ring.

[0041] The water sample collection operation process of the present invention is simple, avoiding the cumbersome process of collecting water samples through the manhole of the ballast tank in the past; at the same time, it has the functions of depth measurement and water sample collection, has a simple and practical structure, and has low manufacturing and procurement costs.

[0042] The above are preferred embodiments of the present invention. Those skilled in the art may also make respective changes or improvements thereon. Without departing from the general concept of the present invention, these changes or improvements shall fall within the scope of protection claimed by the present invention.
