During the rotation of the mounting rod, the slider 2 slides on the inner side of the slide groove 2 under the pull of the output end of the electric push rod. Then, after the distance adjustment mechanism is placed vertically on the sea level, the cylinder is started, and the output end of the cylinder is contracted, so that the main board moves downward with the distance adjustment mechanism at the same time, so that the sampling mechanism is submerged in the sea water;

[0015] S2: Then start the first motor to rotate the gear column, and simultaneously mesh the gear 1 and the gear 2 to rotate the drum 1 and the drum 2 at the same time.

[0018] Compared with the prior art, the present invention provides a water resource multi-point sampler and sampling method, which has the following beneficial effects:

[0019] 1. A multi-point sampler and sampling method for water resources, wherein the first and second rotating drums move downward while rotating, and under the connection of the first Y-shaped plate, the rotating rod moves downward together. During the process, as the first and second rotating drums rotate, and through the connection of the first and second sliding beads, the first sampling tank and the second sampling tank are driven to move upward, and the moving distance between the first sampling tank and the second sampling tank is equal to the moving distance between the second sampling tank and the third sampling tank, so that when the first and second rotating drums move downward to seawater of different depths, the first sampling tank, the second sampling tank, and the third sampling tank can be evenly distributed in the upper, middle, and lower layers of the sampled seawater for sampling, which can be applicable to seawater of different depths, improves versatility, and improves the monitoring accuracy of sampling.

[0020] 2. A multi-point sampler and sampling method for water resources. When the rotating drum 2 is connected to the second threaded rod and rotates downward, the rotating drum 2 will drive the rotary cutter to rotate together, so that the rotary cutter rotates and moves downward at the same time, and the seaweed or kelp in the sampled seawater area can be cut off to avoid the distance adjustment mechanism and the sampling mechanism being entangled by the seaweed when moving, affecting the sampling process.

[0021] 3. A multi-point water resource sampler and sampling method, starting the second motor to drive the gear four to rotate, and then through the gear transmission, the baffle and the blade are rotated and moved away from the opening position, so that seawater enters the first sampling tank, the second sampling tank, and the third sampling tank for sampling. The baffle and the blade rotate one circle and return to their original positions, and then block the opening. During the closing process of the baffle, if there is floating broken seaweed at the opening position, the baffle can rotate to shear the kelp with the cooperation of the blade and the arc plate to avoid the baffle being unable to close due to seaweed or kelp, thereby affecting the sampling.

[0055] S3: When the rotating drum 1 42 and the rotating drum 2 43 move downward in the seawater, the third sampling tank 512 will be driven to move downward together. When the rotating drum 1 42 and the rotating drum 2 43 move downward and rotate, the first sampling tank 510 slides on the inner side of the spiral ring groove 1 44 with the sliding ball 1 54, and moves upward. The second sampling tank 511 slides on the inner side of the spiral ring groove 2 45 with the sliding ball 2 56, and also moves upward. In the process of movement, the distance between the first sampling tank 510 and the second sampling tank 511 is the same as the distance between the second sampling tank 511 and the third sampling tank 512.

[0056] S4: When the rotating drum 1 42 and the rotating drum 2 43 stop moving downward, they also stop rotating. At this time, the first sampling tank 510, the second sampling tank 511 and the third sampling tank 512 are respectively located at different positions of the upper, middle and lower layers in the seawater. Then the second motor 51 is started to rotate the rotating rod 48 with the card strip 49. The card strip 49 is matched with the card slot 526, and the gear 4 525 is driven to rotate at the same time. Through the gear transmission, the baffle 516 and the blade 517 are rotated and moved away from the opening 513 to collect seawater samples.

[0057] When in use, the mobile platform 14 is pushed to the coast where sampling is required, and then the electric push rod 13 is started. The output end of the electric push rod 13 pushes the mounting rod 3 to flip from a vertical state to a horizontal state, and places the distance adjustment mechanism 4 and the sampling mechanism 5 on the sea level. Then the cylinder 16 is started, and the cylinder 16 retracts to cause the main board 1 to drive the distance adjustment mechanism 4 to move downward, and the sampling mechanism 5 is submerged in the sea water. Then, the first motor 422 is started, and the output end of the first motor 422 causes the gear column 423 to rotate. The gear column 423 meshes with the gear 1 417 and the gear 2 418, so that the rotating drum 1 42 and the rotating drum 2 43 rotate at the same time. Because the two are respectively connected with the first threaded rod 419 and the first threaded rod 419, The second threaded rod 420 is threadedly connected, so that the first rotating drum 42 and the second rotating drum 43 can move downward while rotating. At the same time, the rotary cutter 416 rotates with the second rotating drum 43 to rotary cut the seaweed or kelp when moving downward. During the process of the first rotating drum 42 and the second rotating drum 43 rotating downward, the first Y-shaped plate 46 and the second Y-shaped plate 47 that are movably connected to the outer sides of the two can make the rotating rod 48 move downward with the first rotating drum 42 and the second rotating drum 43. During the downward movement, the third sampling tank 512 will not move on the rotating rod 48 under the connection between the third Y-shaped plate 57 and the third ring 59. However, the first sampling tank 510 is moved downward in the first moving When the first sampling tank 510 is connected to the rotating plate 53 and the following sliding ball 54 slides on the inner side of the spiral ring groove 1 44, the first sampling tank 510 is moved upward, and when the second sampling tank 511 is connected to the second moving plate 55 and the following sliding ball 2 56 slides on the inner side of the spiral ring groove 2 45, the second sampling tank 511 is also moved upward, and in the process of the first sampling tank 510 and the second sampling tank 511 moving upward, the distance between the first sampling tank 510 and the second sampling tank 511 is the same as the distance between the second sampling tank 511 and the third sampling tank 512. When the rotating drum 1 42 and the rotating drum 2 43 stop rotating and move downward, the first sampling tank 510 and the second sampling tank 511 are moved upward. The second sampling tank 511 and the third sampling tank 512 are also located in the upper, middle and lower areas of the seawater, respectively. At this time, the second motor 51 is started to rotate the rotating rod 48. While the rotating rod 48 is rotating, the gear four 525 is rotated under the connection of the clamping strip 49. The gear three 520 drives the baffle 516 to rotate through the gear meshing, so that the baffle 516 is moved away from the opening 513, and the seawater enters the first sampling tank 510, the second sampling tank 511 and the third sampling tank 512 at the same time. Then, as the gear three 520 rotates, the baffle 516 moves back to its original position and stops rotating, blocking the opening 513, thereby completing the sampling of multiple layers of seawater.
