[0019] The present patent is further illustrated below with reference to specific embodiments. It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of the patent. Furthermore, it should be understood that after reading the teachings of this patent, those skilled in the art can make various alterations or modifications to this patent, and these equivalent forms also fall within the scope defined by the appended claims.

[0020] See Figure 1 , Figure 2 and Figure 3 This is a schematic diagram of the structure of this patent. A layered environmental protection water sample collector includes a base 1, a column 2 installed on the top of the base 1, a horizontal plate 3 fixedly installed on the top of the column 2, a cylinder 4 fixedly installed on the bottom right side of the horizontal plate 3, a mounting seat 5 fixedly installed on the bottom end of the piston rod of the cylinder 4, a motor 6 fixedly installed on the left side of the mounting seat 5, and a sampling plate 7 fixedly installed through the right end of the rotating shaft of the motor 6 through the mounting seat 5.

[0021] A PLC control system can be installed at the stern to facilitate the electrical control settings of cylinder 4 and motor 6.

[0022] Cylinder 4 is a standard SC series cylinder with a diameter of 50mm, a stroke of 500mm, a working pressure of 0.4-0.7MPa, and a thrust of 785-1374N.

[0023] The sampling disk 7 can be circular, with four sampling chambers located at the four ends of the sampling disk 7, and symmetrical in pairs.

[0024] The sampling tray 7 has sampling chambers at all four ends, and a sampling port 8 is provided on the right side wall of the sampling chamber. A filter screen 9 is fixedly installed on the inner side wall of the sampling port 8.

[0025] Filter 9 prevents floating objects on the water surface from entering the sampling chamber.

[0026] Connecting plates 10 are fixedly installed at both the upper and lower ends of the shaft sidewall of motor 6. The connecting plates 10 are provided with sliding holes. A sliding rod 11 is slidably installed on the inner sidewall of the sliding holes. A first circular plate 12 is fixedly installed at the left end of the sliding rod 11. A spring 13 is sleeved on the sidewall of the sliding rod 11. The two ends of the spring 13 are fixedly installed on the first circular plate 12 and the connecting plate 10, respectively. A baffle 14 is fixedly installed at the right end of the sliding rod 11 through the left sidewall of the sampling chamber and the sampling port 8.

[0027] Figure 1 The spring 13 shown is in a compressed state. The compression effect of the spring 13 can cause the baffle 14 to exert leftward pressure, thereby pressing the left side of the rubber ring 20 against the right side of the sampling disk 7.

[0028] Spring 13 is made of stainless steel with a wire diameter of 2mm, an outer diameter of 15mm, a free length of 50mm, and an elastic modulus of 10N / mm, ensuring that baffle 14 can generate sufficient sealing pressure under spring compression.

[0029] Specifically, mounting holes are provided at the four corners of the top of the base 1, and bolts 15 are provided inside the mounting holes.

[0030] The base 1 can be fixed to the top and stern of the hull by bolts 15.

[0031] Specifically, a circular groove is provided at the top center of the base 1, and a bearing 16 is fixedly installed on the inner side wall of the circular groove. The top of the inner ring of the bearing 16 is fixed to the bottom end of the column 2.

[0032] After sampling is completed, column 2 can be rotated around its axis to move the sampling disk 7 to the upper side of the hull. Figure 1 The sampling plate 7 is located on the upper side of the water surface, which facilitates the removal of water samples through the outlet pipe 21.

[0033] Specifically, a pull rod 17 is integrally formed on the side wall of the first circular plate 12.

[0034] The pull rod 17 is designed to facilitate the left and right movement of the first circular plate 12.

[0035] Specifically, a sliding sealing ring is installed on the inner wall of the through hole on the left side wall of the sampling chamber.

[0036] Specifically, the baffle 14 includes a second circular plate 18, and an annular groove 19 is provided at the left edge of the second circular plate 18. A rubber ring 20 is fixedly installed in the annular groove 19, and the left side of the rubber ring 20 is tightly attached to the outer right side wall of the sampling plate 7.

[0037] The sliding seal ring and rubber ring 20 are made of fluororubber, which has the characteristics of high temperature resistance, oil resistance and chemical corrosion resistance, and the working temperature range is -20℃ to 200℃, meeting the use requirements of different aquatic environments.

[0038] A detachable gland structure can be designed at the annular groove 19 where the rubber ring 20 is located and at the installation location of the sliding seal ring, so as to facilitate quick replacement after the seal wears or ages.

[0039] Specifically, the four ends of the outer wall of the sampling plate 7 are each equipped with a water outlet pipe 21, and the water outlet pipe 21 is equipped with a switch valve. The water outlet pipe 21 is connected to the sampling chamber.

[0040] Working principle: During sampling, the cylinder 4 controls the mounting base 5, sampling plate 7 and other structures to move downward until the bottom of the sampling plate 7 enters below the water surface, that is, the sampling port 8 below enters below the water surface. Then, the pull rod 17 is moved to the right to move the baffle 14 to the right, so that the water sample enters the corresponding sampling chamber through the sampling port 8. When the pull rod 17 is released, the rebound effect of the spring 13 causes the baffle 14 to re-seal the right side of the sampling port 8.

[0041] Move the vessel to another sampling area, and use motor 6 to rotate sampling disc 7 so that the remaining sampling chambers can be rotated to the bottom. Then, repeat the sampling operation as described above.

[0042] It should be noted that the device structure and accompanying drawings of this patent mainly describe the principle of this patent. In terms of the technical aspects of this design principle, the setting of the device's power mechanism, power supply system and control system is not fully described. However, those skilled in the art who understand the principle of the above patent can clearly understand the specifics of its power mechanism, power supply system and control system.

[0043] This patented device features a mounting base at the bottom of a cylinder, on which a motor is installed. The motor drives a sampling disc to rotate. The sampling disc has four sampling chambers inside. By rotating the sampling disc, water samples from different locations can enter different sampling chambers, allowing a single sampling structure to collect water samples from multiple locations. The device is easy to operate and can efficiently and accurately complete the task of stratified water sample collection, meeting the environmental testing field's requirements for water sample purity and ease of operation.
