The invention activates the multi-head sampling mechanism through the operating control mechanism when sampling, and in the process of sampling, not only can water bodies at different positions be sampled, but the sampled samples can also be saved, and after sampling a position, it is not necessary to take it to the shore to take it down, and sampling can be continued, and in the sampling process, the water quality can be tested for pH in advance, so that the staff can understand the water quality in advance, and avoid the need to take away the sampled water body when sampling a water sample at a position during the sampling process. Sampling again will increase the sampling time and reduce the efficiency of sampling.

[0004] In the above-mentioned prior art, the staff puts the device on the water surface, drives the device to move on the water surface through the driving component, sinks the sampling component through the control structure, and uses the multi-head sampling mechanism to sample water bodies at different locations. However, the water environment is different in different water sources. When the sampling structure sinks to a deep depth, the sampling structure is likely to come into contact with aquatic plants. When the sampling device moves, it is likely to be entangled with the aquatic plants, thus affecting the movement of the sampling structure and sampling. Summary of the Invention

[0005] The purpose of the present invention is to solve the problem in the prior art that the water environment is different in different water sources.

The first motor 12 is fixedly connected on both sides of the bottom end of the support plate 11, and the side of the first motor 12 away from each other is transmission-connected with the first rotating shaft 13, and the end of the first rotating shaft 13 away from the first motor 12 is fixedly connected with a rotating paddle 14, and the pay-off assembly includes a bracket 21, and the bracket 21 is fixed to the top of the support plate 11, and the middle part of the bottom end of the bracket 21 is rotatably connected to the second rotating shaft 23, one end of the second rotating shaft 23 passes through the bracket 21, and the end of the second rotating shaft 23 located outside the bracket 21 is transmission-connected to the second motor 22, and the middle part of the second rotating shaft 23 is wrapped with a rope 24, and one end of the rope 24 slides through the support plate 11 and is fixedly connected to the top of the sampling barrel 31.

[0041] In this embodiment, the staff places the device into the water and starts the first rotating shaft 13. The first rotating shaft 13 drives the rotating paddle 14 to rotate. The rotating paddle 14 drives the positioning block 15 to rotate. The positioning block 15 rotates to drive the device to move in the water. When it moves to the specified position, the second motor 22 is started to drive the second rotating shaft 23 to rotate. The second rotating shaft 23 drives the rope 24 to unwind. At this time, the sampling bucket 31 sinks into the water for sampling. When the sampling is completed, the second motor 22 reverses to drive the rope 24 to reel in, and the sampling bucket 31 rises. The positioning block 15 is located inside the limit block, thereby limiting the sampling bucket 31 to prevent instability when the sampling bucket 31 moves.

[0042] Working principle: First, the staff puts the device into the water and starts the first rotating shaft 13. The first rotating shaft 13 drives the rotating paddle 14 to rotate, and the rotating paddle 14 drives the positioning block 15 to rotate. The positioning block 15 rotates and drives the device to move in the water. When it moves to the designated position, the second motor 22 is started to drive the second rotating shaft 23 to rotate, and the second rotating shaft 23 drives the rope 24 to unwind. At this time, the sampling barrel 31 sinks into the water, and the motor 332 is started to drive the fourth rotating shaft 333 to rotate. The fourth rotating shaft 333 drives the gear 334 to rotate. The gear 334 engages with the rack 335 to rotate, and the rotating ring 331 drives the camera 336 and the protective cover 337 to rotate at the top of the fixed ring 33. The staff can observe the environmental conditions in the water in real time according to the camera 336 to avoid The sampling bucket 31 sinks into the water environment with harsh terrain, and the protective cover 337 can waterproof and protect the camera 336 to prevent the camera 336 from being damaged in the water. When sampling, a solenoid valve 315 is opened, and water flows into a sampling chamber 312 along the water inlet pipe 314. When the sampling chamber 312 is full of water, the solenoid valve 315 is closed to stop sampling. At this time, the first rotating shaft 13 is started again to drive the positioning block 15 to rotate, so that the support plate 11 drives the sampling bucket 31 to move to another place and repeat the operation to sample again. When there are aquatic plants in the water, the third motor 321 is started to drive the third rotating shaft 322 to rotate, the third rotating shaft 322 drives the fixing seat 323 to rotate, the fixing seat 323 drives the L-shaped blade 324 to rotate, and the L-shaped blade 324 drives the cleaning The cleaning plate 325 rotates, and the L-shaped blade 324 rotates to cut the weeds near the sampling bucket 31, thereby preventing the water weeds from winding around the sampling bucket 31. When the L-shaped blade 324 rotates, the L-shaped blade 324 drives the cleaning plate 325 to rotate, and the cleaning plate 325 can clean the outer wall of the filter cover 313 to prevent the cut weeds or garbage in the water from adhering to the outer wall of the filter cover 313 and affecting the sampling work of the sampling bucket 31. When the L-shaped blade 324 cuts the water weeds, each time the L-shaped blade 324 rotates and passes through the first anti-winding blade 326, the first anti-winding blade 326 can cut the water weeds wound on the L-shaped blade 324, thereby preventing the L-shaped blade 324 from being unable to cut the water weeds near the sampling bucket 31 after the water weeds are wound around it, and the second anti-winding blade 329 can The second anti-winding blade 329 and the water grass wrapped around the movable limiting ring 328 are cut to prevent the movable limiting ring 328 from sliding with the rotation of the L-shaped blade 324, and the protective cover 337 will adhere to water grass or other garbage on the surface in the water. Therefore, when the cleaning plate 325 drives the fixed plate 34 to move, the cleaning wiper 343 will contact the protective cover 337, and the force generated by the contact will squeeze the cleaning wiper 343. After the cleaning wiper 343 is pressed, it will gradually slide to one side of the fixed plate 34. In the initial state, the cleaning wiper 343 will be in the same vertical device. When squeezed, it will fit into the outer wall of the protective cover 337 in an arc shape. Therefore, the outer wall of the protective cover 337 can be cleaned to avoid affecting the line of sight of the camera 336.
