[0032] In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not limiting. Therefore, other examples of the exemplary embodiments may have different values.

[0033] It should be noted that like reference numerals and letters refer to like items in the following figures, and therefore, once an item is defined in one figure, it need not be further discussed in subsequent figures.

[0034] Example

[0035] like Figures 1 to 9 As shown, the water sample collection system for water quality detection in this embodiment includes a carrier and a sampling barrel 200, the sampling barrel 200 is arranged on the carrier, the carrier is a floating platform 111, the carrier includes a drone 112 and the floating platform 111, the sampling barrel 200 is arranged on the floating platform 111, and a vertical driving device is provided on the floating platform 111, and the vertical driving device drives the sampling barrel 200 to extend downward from the bottom of the floating platform 111; the sampling barrel 200 includes a sampling cavity 201, the sampling cavity 201 is a cylindrical structure with upper and lower openings, and a layering mechanism 240 is provided on one side of the sampling cavity 201, and the action of the layering mechanism 240 can divide the sampling cavity 201 into a plurality of vertically arranged separation cavities.

[0036] Through the scheme of this embodiment, a remote control module is provided on the floating platform 111, which can send sampling instructions to it by remote control; after the drone 112 drives the floating platform 111 to the position, the drone 111 releases the floating platform 111 to the water surface, and the vertical drive device is started to move the sampling cylinder 200 downward, so that the sampling cylinder 200 enters the water body. Due to the structure of the upper and lower openings, the water body to be sampled can enter the sampling cavity 201 from the bottom according to the original stratification, and the stratification mechanism 240 is started to divide the sampling cavity 201 into several separation cavities, so that different water layers are sealed and preserved, avoiding the mixing of different layers of water caused by shaking during transportation, and completing the stratified sampling of the water body.

[0037] After sampling is complete, drone 112 retrieves platform 111 by grabbing it. Platform 111 is topped with a hanger 113, which has a horizontal beam mounted on top. The bottom of drone 112 is equipped with a remotely controlled gripper 114. Gripper 114 grips the beam on top of hanger 113, lifting platform 111 and completing the recovery.

[0038] The sides of the partition chambers in this embodiment are all provided with output ports (not shown in the figure), and the output ports are provided with devices such as switch valves or plugs for sealing.

[0039] In this or other embodiments, a sampling trough 101 is provided at the bottom of the floating platform 111. The area of ​​the sampling trough 101 is larger than the diameter of the sampling barrel 200, and the sampling barrel 200 is disposed in the sampling trough 101. The provision of the sampling trough 101 prevents the floating platform 111 from disturbing the surface water during placement, ensuring that surface microorganisms can be collected and improving sampling accuracy.

[0040] In order to ensure the stability of the floating platform 111 after it is placed, extension blocks 115 are provided around the top of the floating platform 111 to reduce shaking during the sampling process.

[0041] In this or other embodiments, the vertical drive device includes a vertical motor 121 and a vertical gear 122. A first rack 211 is provided on the side of the sampling barrel 200, meshing with the vertical gear 122. The sampling barrel 200 is slidably connected to the floating platform 111. The rotation of the vertical motor 121 drives the vertical gear 122 to drive the first rack 211, thereby achieving the up and down movement of the sampling barrel 200. The delamination mechanism 240 is provided on the sampling barrel 200 and can move with the sampling barrel 200, allowing separation measures to be taken at any time.

[0042] In this embodiment or other embodiments, the sampling tube 200 includes a main body 210 and an extension tube 220. The extension tube 220 is slidably connected to the main body 210. The sampling chamber 201 is provided in both the main body 210 and the extension tube 220. The extension tube 220 is driven downwardly by an extension drive mechanism to extend out of the main body 210. After the main body 210 moves downward, the extension tube 220 can continue to extend downward, thereby increasing the depth of sampling; after the sampling is completed, the extension tube 220 can be retracted into the main body 210. While ensuring that the sampling tube 200 can collect water at a deeper depth, the height of the device is reduced, thereby lowering the center of gravity and reducing the shaking of the floating platform 111 during the movement, ensuring the accuracy of sampling, and reducing the influence of wind and water flow, thereby improving the stability of the device and ensuring that the device can operate safely.

[0043] In this embodiment or other embodiments, the extension drive mechanism includes a transmission gear set 230, which is rotatably connected to the lower end of the first rack 211, and the transmission gear set 230 is engaged with the second rack 221 on the side of the extension tube 220. The transmission gear set 230 is rotatably connected to the main body 210. When the main body 210 is at the top, the vertical movement motor 121 is engaged with the transmission gear set 230. The rotation of the vertical movement motor 121 can drive the transmission gear set 230 to rotate first, thereby driving the extension tube 220 to move downward and extend out of the main body 121. When the extension tube 220 extends to the bottom, the transmission gear set 230 is limited by the second rack 221, so that the vertical movement motor 121 drives the driving body 210 to move downward, and then engages with the first rack 211, and continues to rotate to drive the main body 210 to move downward.

[0044] When sampling is completed, the vertical shift motor 121 rotates in the opposite direction to drive the main body 210 to move upward. When it reaches the top, the vertical shift gear 122 contacts and engages with the transfer gear set 230, and continues to rotate to cause the transfer gear 230 to rotate and drive the extension tube 220 to move upward until it is completely retracted into the main body 210.

[0045] The transmission gear set 230 in this embodiment is composed of two meshing gears, one of which is meshed with the second rack 221, and the other is arranged below the first rack 211. This arrangement allows the vertical movement motor 121 to drive the extension tube 220 and the main body 210 to move in the same direction without switching the rotation direction.

[0046] A layered structure 240 is provided in both the extension tube 220 and the main body 210 to ensure that the sampling cavities 201 in the extension tube 220 and the main body 210 can be separated and sealed.

[0047] In this embodiment or other embodiments, a first suction cup 261 is concentrically fixed around the bottom of the main body 100, and the first suction cup 261 is fixed to a sliding sleeve 262, and the sliding sleeve 262 is slidably connected to the bottom of the main body 210; the top of the sliding sleeve 262 is connected to the main body 210 through a tensioning spring 263, and a sealing ring 264 is provided on the main body 210 above the tensioning spring 263.

[0048] As the main body 210 moves upward, the sealing ring 264 forms a piston structure with the floating platform until the first suction cup 261 is pressed against the bottom of the floating platform. The main body 210 continues to move upward, and the sealing ring 264 continues to move upward, generating negative pressure between the sealing ring 264 and the first suction cup 261, ensuring that the first suction cup 261 is sucked and pressed against the bottom of the floating platform 210. This ensures that the main body 210 and the floating platform 111 maintain a tight suction connection, reducing the load on the vertical movement mechanism and improving the stability of the device.

[0049] In order to ensure that the first suction cup 261 is tightly adsorbed to the bottom surface of the floating platform 111 and avoid a large gap, the main body is configured as a cylindrical structure to reduce the gap between the main body 210 and the floating platform 111 due to the corner.

[0050] like Figure 9 As shown, in another embodiment, second suction cups 250 are fixed to both sides of the bottom of the body 210. The second suction cups 250 can be sucked upward and fixed to the bottom surface of the floating platform 111. The second suction cups 250 can fix the body 210 to the floating platform 111, thereby preventing the body 210 from moving when the vertical movement motor 121 drives the extension cylinder 220, ensuring that the extension cylinder 220 and the body can move smoothly and sequentially.

[0051] In this embodiment or other embodiments, the layering mechanism 240 includes a layering driver and a plurality of layering sheets 242. The layering sheets 242 are arranged in parallel. The layering driver can drive the layering sheets 242 to be inserted into or removed from the sampling cavity 201. The sampling cavity 201 is divided into a main cavity 202 and a secondary cavity 203 by a partition 204. The layering sheets 242 are slidably connected to the partition 204. During sampling, the layering sheets 242 move through the secondary cavity 203 into the main cavity 202, dividing the main cavity 202 into a plurality of separate cavities.

[0052] The secondary cavity 203 can guide the movement of the layered sheet 242, ensuring that the layered sheet 242 can smoothly enter the main cavity 202, and the secondary cavity 203 can provide a temporary storage location for the layered sheet 242 to avoid extending into the main cavity 202 and causing interference with the water flow when the water enters the main cavity 202.

[0053] In this embodiment or other embodiments, the stratified drive includes a stratified drive motor 241, a drive screw 243 and a mounting plate 244, the stratified sheets 242 are vertically fixed to the mounting plate 244, the drive screw 243 is rotatably connected to the mounting plate 244 and is driven to rotate by the stratified drive motor 243.

[0054] The driving screw 243 is threadedly connected to the body 210 , and the layered driving motor 241 drives the driving screw 243 to rotate, so that the driving screw 243 pushes or pulls the mounting plate 244 to move.

[0055] In the figure, the drive screw 243 is fixedly connected to the mounting plate 244, and an end gear is threadedly connected to the drive screw 243. The end gear is rotationally connected to the main body 210, and the layered drive motor 241 is engaged with the end gear. The rotation of the end gear can push or pull the mounting plate 244 to move.
