[0002] Oil pollution refers to the pollution caused by the leakage and emission of oil during the processes of oil exploration, transportation, loading and unloading, processing and use, mainly occurring in the ocean. The oil floats on the sea surface and quickly spreads to form an oil film, which can migrate and transform through diffusion, evaporation, dissolution, emulsification, photodegradation, biodegradation and absorption, etc.

[0003] In order to better and accurately purify the ocean, it is necessary to take out the seawater polluted by oil for detection. However, the existing sampling equipment has a simple structure and requires staff to manually draw water. Inevitably, the outside of the sampling bottle comes into contact with seawater and is contaminated, which is not conducive to the next transfer. Therefore, we propose a sampling device for seawater oil pollution prevention and control analysis. Content of the Utility Model

The transmission shaft 24 is drivingly connected to the screw 23;

[0022] Oil pollution refers to the pollution caused by the leakage and emission of oil during the processes of oil exploration, transportation, loading and unloading, processing and use, mainly occurring in the ocean. Oil floats on the sea surface and quickly spreads to form an oil film, which can migrate and transform through diffusion, evaporation, dissolution, emulsification, photodegradation, biodegradation and absorption, etc.;

[0023] In order to better and accurately purify the ocean, it is necessary to take out the seawater contaminated with oil for testing. However, the existing sampling equipment has a simple structure and requires manual water intake by staff. Inevitably, the outer side of the sampling bottle comes into contact with seawater and gets contaminated, which is not conducive to the next step of transfer;

[0024] Start the motor 25. The motor 25 drives the screw 23 to rotate by means of the transmission shaft 24. The screw 23 rotates on its own under the action of the bearing. The threaded sleeve 31 rises or falls inside the limit chute 22 according to its rotation direction. Here, it is assumed to be in the descending state. The movable plate 3 drives the water pump 32 to move downward. The suction pipe 33 moves downward into the water. The water pump 32 is started, and water enters the suction pipe 33 and is then transmitted to the water delivery pipe 34 and finally enters the sample storage bottle 4;

[0025] It can ensure that the sample storage bottle 4 completes the loading of seawater without touching the seawater. At the same time, the entire sampling process can be handed over to components such as the water pump 32 and the movable plate 3. The suction pipe 33 can automatically enter the seawater to extract seawater, and the staff can then free their hands to observe the sampling situation without having to take water themselves, making it more convenient to use.

[0026] In other embodiments, this embodiment discloses, please refer to Figure 1 As shown, a connecting through groove 10 is opened at the corresponding position inside the device base 1 and the suction pipe 33. The suction pipe 33 is slidably connected to the inside of the connecting through groove 10; through this design, the structure of the sampling mechanism can be improved, enabling the suction pipe 33 to enter the water better.

[0027] In other embodiments, this embodiment discloses, please refer to Figure 1 As shown, the bottom end face of the device base 1 is provided with bottom supports 11 distributed at the four corners. Anti-slip pads are provided at the bottom ends of the four bottom supports 11; through this design, the use stability of the device base 1 can be improved, increasing the friction between the device base 1 and its placement platform and preventing it from slipping.

[0028] In other embodiments, this embodiment discloses, please refer to Figure 2 As shown, a limit placement groove 12 is opened on the top end face of the device base 1. The sample storage bottle 4 is movably connected to the inside of the limit placement groove 12. One end of the water delivery pipe 34 is connected to the sample storage bottle 4; through this design, the connection between the sample storage bottle 4 and the device base 1 is more stable and will not slip during use.

[0029] Embodiment 2:

[0030] In other embodiments, this embodiment discloses, please refer to Figure 2 、 Figure 4As shown, it further includes a reinforcement mechanism. The reinforcement mechanism includes a connection port 41, which is opened at the top port of the sample storage bottle 4. The water delivery pipe 34 is movably connected to the inside of the connection port 41 and one end extends to the inside of the sample storage bottle 4. An empty slot 42 is opened inside the connection port 41. A spring 43 is provided inside the empty slot 42. The other end face of the spring 43 is provided with a pressing plate 44. One end of the pressing plate 44 is located inside the connection port 41 and is movably connected to the outer side of the water delivery pipe 34;

[0031] Insert the water delivery pipe 34 into the connection port 41. The water delivery pipe 34 first touches the connection port 41 and pushes the connection port 41 backward. The spring 43 contracts to a suitable position, and at the same time, the pressing plate 44 is pushed to closely adhere to the outer side of the water delivery pipe 34, so that the water delivery pipe 34 can be fixed. When the water delivery pipe 34 slides up and down, the pressing plate 44 and the spring 43 both remain in their original states and do not completely fix the water delivery pipe 34; it can improve the connection tightness between the water delivery pipe 34 and the sample storage bottle 4, and at the same time does not affect the flexibility of the water delivery pipe 34 during lifting and lowering, and can better optimize the connection between the sampling mechanism and the sample storage bottle 4.

[0032] The above describes the embodiments of the present invention in detail with reference to the accompanying drawings. However, the present invention is not limited to this. Within the scope of knowledge possessed by those skilled in the art to which it belongs, various changes can be made without departing from the gist of the present invention.
