[0002] Currently, quantitative sampling of phytoplankton in surface water is generally carried out by staff on-site using water samplers. Because it is a manual operation, it is difficult to control the sampling depth consistently each time, or to control different sampling depths according to actual needs. At the same time, if the sample volume at the same depth is large, staff need to stay on-site for a long time, which is time-consuming and labor-intensive. Mechanical operation is difficult to automate. Utility Model Content

They are only for the convenience of describing this utility model and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0019] like Figures 1-2 As shown, a remote automatic phytoplankton quantitative sampling device includes a sampling module, a control module, and a float 1. The sampling tube 2 of the sampling module passes through and extends out of the float 1 along the central axis of the float 1. The sampling tube 2 and the float 1 are detachably connected. The length of the end of the sampling tube 2 that extends out of the float 1 away from the sampling module is determined according to the sampling depth of the phytoplankton. The float 1 and the sampling tube 2 are fixed together. During operation, the end of the sampling tube 2 that extends away from the sampling module extends vertically downward into the water. In a preferred embodiment, the part of the sampling tube 2 that extends into the water is preferably made of a material with a certain degree of hardness to prevent the sampling tube 2 from bending in the water, which would affect the sampling depth of the phytoplankton. The part of the sampling tube 2 that connects to the sampling pump 4 is preferably made of a flexible hose to facilitate the reasonable setting of the positions of the float 1 and the device box 14.

[0020] The sampling module includes a sampling pump 4, a dosing pump 5, a drain pump 3, a reagent bottle 6, and a sampling bottle 7. The end of the sampling tube 2 furthest from the water source is connected to the inlet of the sampling pump 4, and the outlet of the sampling pump 4 is connected to the sampling bottle 7 via a first flexible hose 12. The inlet of the dosing pump 5 is connected to the reagent bottle 6 via a second flexible hose 15, and the outlet of the dosing pump 5 is connected to the sampling bottle 7 via a third flexible hose 11. The inlet of the drain pump 3 is connected to the sampling bottle 7 via a fourth flexible hose 13, and the outlet of the drain pump 3 is connected to the external environment via a fifth flexible hose. The sample bottle 7 has a detachable rain cover 8 that fits the external shape of the sample bottle 7. The opening of the rain cover 8 faces downward. The top of the rain cover 8 has an internal groove that fits the opening of the sample bottle 7. The opening of the sample bottle 7 is inserted into the internal groove to connect and fix the sample bottle 7 to the rain cover 8. The top of the rain cover 8 has three holes that allow the first hose 12, the third hose 11, and the fourth hose 13 to pass through, so that the ends of the first hose 12, the third hose 11, and the fourth hose 13 can all extend into the sample bottle 7.

[0021] The control module includes a controller and a wireless communication unit. The controller communicates with the power equipment of the sampling module through the wireless communication unit, thereby controlling the working status of the power equipment. The power equipment here includes a sampling pump 4, a dosing pump 5, and a drainage pump 3. Specifically, the wireless communication unit uses a wireless router 17. The wireless router 17 can send and receive wireless network signals through an IoT card. The power cords of the sampling pump 4, the dosing pump 5, and the drainage pump 3 are plugged into three smart sockets 18 respectively. The sampling time and sampling volume can be set remotely. The controller sends control signals to remotely control the circuit switch and control the working status of the sampling pump 4, the dosing pump 5, and the drainage pump 3, realizing remote operation and automatic editing, and realizing timed and quantitative sampling.

[0022] Preferred implementation methods, such as Figure 2 As shown, the rain cover 8 allows for free adjustment of the lengths of the first hose 12, the third hose 11, and the fourth hose 13 extending into the sampling bottle 7. It is recommended that the lengths of the first hose 12, the third hose 11, and the fourth hose 13 extending into the sampling bottle 7 be made of a material with a certain degree of hardness. The end of the first hose 12 extends to the bottom of the sampling bottle 7 to achieve stable sample collection. By controlling the height difference between the ends of the first hose 12 and the fourth hose 13, the sample volume in the sampling bottle 7 can be controlled. Excess liquid sample in the sampling bottle 7 is discharged through the fourth hose 13 and the drain pump 3. To avoid reagent contamination, the end of the third hose 11 is higher than the end of the fourth hose 13, approximately 1 cm higher.

[0023] In a preferred embodiment, the sampling device further includes a device housing 14, within which a horizontal partition 19 is provided. The upper part of the horizontal partition 19 houses the wireless communication unit, a power strip, and a smart socket 18, while the lower part houses the sampling pump 4, a dosing pump 5, a drain pump 3, and a reagent bottle 6. Multiple through holes 16 are provided on the side wall of the device housing 14, below the horizontal partition 19, to allow the sampling tube 2, the fifth flexible tube, the first flexible tube 12, the third flexible tube 11, and the fourth flexible tube 13 to pass through. Specifically, the sampling tube 2 passes through the first through hole 16 and connects to the float 1; the fifth flexible tube passes through the third through hole 16 to communicate with the external environment, facilitating the drainage of excess liquid from the sampling bottle 7; the first flexible tube 12, the third flexible tube 11, and the fourth flexible tube 13 pass through the second through hole 16 and connect to the sampling bottle 7.

[0024] Preferably, the sampling device further includes a sample box 9, the lower part of the sampling bottle 7 is fixed in the sample box 9, and the sampling bottle 7 and the sample box 9 are detachably connected to facilitate the installation and removal of the sampling bottle 7. A drain outlet 10 is provided on the side wall of the sample box 9. The drain outlet 10 is used to drain rainwater and excess sample in the sample box 9. Before the formal sampling begins, the sampling pump 4 is turned on to completely drain the sample remaining in the sampling tube 2 and the first flexible tube 12 from the previous sampling, so that it flows into the sample box 9 and is discharged from the drain outlet 10, and then the formal sampling begins.

[0025] In a preferred embodiment, the sampling pump 4, dosing pump 5, and drain pump 3 are preferably peristaltic pumps. The reagent bottle 6 contains Lugol's solution to achieve quantitative sample fixation. The device box 14 and sample container 9 can be placed on a floating platform, on a boat, on the shore, or in other locations.

[0026] The working process of a remote automatic phytoplankton quantitative sampling device is as follows: First, a new sampling bottle 7 is placed in the sample box 9, and a rain cover 8 is inserted into the opening of the sampling bottle 7. The operator sets the height of the fourth hose 13 port inside the sampling bottle 7 according to the required sampling quantity, and sets the length of the sampling tube 2 extending beyond the float 1 according to the sampling depth. The controller remotely controls the operation of the sampling pump 4 and the drainage pump 3. The sampling pump 4 draws the sample from the required sampling depth into the sampling bottle 7. When the liquid in the sampling bottle 7 comes into contact with the port of the fourth hose 13, the drainage pump 3 drains the excess liquid in the sampling bottle 7 into the external environment through the fifth hose. The controller remotely controls the operation of the dosing pump 5, which adds reagents to the sampling bottle 7 to fix the sample. The controller then remotely stops the operation of the sampling pump 4, the drainage pump 3, and the dosing pump 5, completing the automatic sampling. After sampling is completed, nearby personnel are notified to collect the collected samples and replace the sampling bottle 7 for future use.
