Rotating rod 11 side wall is fixedly connected with cam 12, and the rotation of cam 12 can convert the rotary motion of motor 10 into the reciprocating motion of rotating bar 13. Cam 12 side wall is rotatably connected with rotating bar 13, and rotating bar 13 reciprocates under the action of cam 12, to pull fixed block 14. Rotating bar 13 side wall is rotatably connected with fixed block 14, and fixed block 14 can move along with the swing of rotating bar 13, and transmits motion to connecting plate two 15. Fixed block 14 side wall is fixedly connected with connecting plate two 15, and connecting plate two 15 moves up and down under the drive of fixed block 14, to pull connecting rod 16. Connecting plate two 15 lower surface is fixedly connected with connecting rod 16, and connecting rod 16 plays the role of connecting connecting plate two 15 and piston 17, and transmits the up-and-down motion of connecting plate two 15 to piston 17, to drive piston 17 to move up and down inside sampler 5. Connecting rod 16 lower surface is fixedly connected with piston 17, and piston 17 slides up and down inside sampler 5 under the drive of connecting rod 16, and the upper surface of piston 17 is fixedly connected with batten 18, and batten 18 can increase the connection stability between piston 17 and connecting rod 16, to ensure that the connection of piston 17 and connecting rod 16 is firm and reliable during movement, without loose or falling off etc.Meanwhile, the gasket plate 18 is attached to the inner wall of the sampler 5, and the gasket plate 18 is made of silica gel, which has good flexibility and sealing performance, can effectively fill the small gap between the piston 17 and the inner wall of the sampler 5, prevent seawater from leaking from the gap during the movement of the piston 17, improve the sealing performance of the equipment, and the inner wall of the gasket plate 18 is fixedly connected to the side wall of the connecting rod 16, which further enhances the connection strength between the gasket plate 18 and the connecting rod 16.

When the device reaches the specified depth, start the motor 10, the motor 10 drives the cam 12 to rotate, and then the cam 12 drives the rotating bar 13 to rotate. The rotating bar 13, as a transmission component, can convert the rotation of the cam 12 into linear motion, pulling the connecting plate two 15 to move upwards. The connecting plate two 15 moves upwards under the pull of the rotating bar 13, playing the role of connection and transmission of motion, transmitting the pulling force of the rotating bar 13 to the connecting rod 16, so that the connecting rod 16 can move upwards together, thereby driving the piston 17 to move upwards. The piston 17 can stably move upwards inside the sampler 5. When the piston 17 moves upwards, a negative pressure is formed inside the sampler 5, thereby drawing seawater into the sampler 5, realizing the function of seawater extraction. During the extraction process, the backing plate 18 will slowly adhere to the inner wall of the sampler 5. The backing plate 18 is made of silicone material, which has good flexibility and sealing performance. When the backing plate 18 adheres to the inner wall of the sampler 5, it can effectively fill the small gap between the piston 17 and the inner wall of the sampler 5, preventing seawater from leaking from the gap during the movement of the piston 17, achieving good sealing effect, ensuring that seawater does not leak out during sampling, and avoiding the entry of shallow seawater into the device, thereby ensuring the accuracy and reliability of the detection effect of the device. When seawater is drawn into the sampler 5, the detector 6 can obtain the basic physicochemical parameters of seawater in real time. The detector 6 can quickly and accurately measure and analyze various basic physicochemical parameters in the seawater sample, such as pH, salinity, temperature, dissolved oxygen, etc. By obtaining these parameters in real time, timely and accurate data support can be provided for marine scientific research, environmental monitoring, etc. Through the setting of multiple samplers 5, multiple points can be simultaneously sampled and detected, and the setting of multiple samplers 5 greatly improves the working efficiency and detection range of the device. Thus, the spatial differences and variation rules of the marine environment can be more comprehensively and systematically understood.

The pull rope 9 also plays a key role in the recovery process of the device, which can bear the weight of the device, ensuring that the device remains stable during the recovery process, avoiding shaking, collision, etc. during the rising process, thereby protecting the device from damage, and also ensuring the safety and integrity of the obtained detection data.

The filter screen 19 is internally provided with a clamping hole 20, which cooperates with a clamping block 25 to fix the position of the filter screen 19, ensure the stable installation of the filter screen 19 in the collection head 7, and prevent displacement or shaking of the filter screen 19 under the impact of seawater flow and the like, thereby ensuring the stability of the filtering effect. The collection head 7 is internally provided with a mounting block 21, which serves as a mounting base for other components and plays a role in fixing and supporting related components, ensures the accurate relative position between components, and enables the filter assembly to work normally. The sidewall of the mounting block 21 is fixedly connected with a pressing block 24, which facilitates the operator to exert an external force, thereby realizing the installation and disassembly operation of the filter screen 19. The sidewall of the mounting block 21 is slidably connected inside the collection head 7, and this sliding connection mode enables the mounting block 21 to move smoothly and linearly inside the collection head 7, ensuring the consistency and coordination of the movement of components connected to the mounting block 21. The sidewall of the pressing block 24 is slidably connected inside the collection head 7. The mounting block 21 is internally fixedly connected with a fixing column 22, which provides a mounting support point for a spring 23. The sidewall of the fixing column 22 is sleeved with the spring 23, one end of which is fixedly connected inside the collection head 7, and the other end is fixedly connected to the sidewall of the fixing column 22. The spring 23 plays a role in elastic reset in the filter assembly. The sidewall of the mounting block 21 is fixedly connected with the clamping block 25, which is slidably connected to the inside of the collection head 7 and the inside of the filter screen 19, ensuring the stability and accuracy of the clamping block 25 during movement, enabling it to accurately insert or disengage from the clamping hole 20, realizing the stable connection or separation between the filter screen 19 and the collection head 7, and facilitating the replacement and maintenance of the filter screen 19.
