DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] Example 1: Refer to the attached specification Figure 1-4 The utility model is an unmanned boat for water layer sampling, comprising a hull 1, see Figure 1 , the top of the hull 1 is hinged with a cover plate 2, see Figure 3A control component 3 and a first motor 4 are fixedly installed inside the hull 1, and a rotating shaft 5 is fixedly connected to the output shaft of the first motor 4. A limiting component 6 is inserted into the outer wall of the rotating shaft 5, and a plurality of sampling tanks 7 are inserted into the inner part of the limiting component 6. A pressure sensor 8 is provided at the bottom of one of the sampling tanks 7, and the pressure sensor 8 is fixedly installed inside the hull 1. The sampling tanks 7 are arranged inside the hull 1, and a plurality of sampling tanks 7 are fixedly connected to the tops of the plurality of sampling tanks 7. A sealing component 10 is rotatably connected between the sampling tanks 7 and the water bucket 9. An arc-shaped tooth plate 11 is provided on the outer wall of the sealing component 10, and the arc-shaped tooth plate 11 is fixedly installed inside the hull 1.

[0023] It should be noted that, when the staff needs to use an unmanned boat to sample water, first the staff needs to control the unmanned boat to move to the top of the water body where sampling is required through the controller, and then control the second motor 17 to work, so that the second motor 17 drives the support plate 16 to rotate, and then the support plate 16 relaxes the water pipe 15, allowing the water pipe 15 to be driven by the counterweight 19 to descend into the water body. When the counterweight 19 drives the water pipe 15 to descend to the depth required for sampling, the staff controls the second motor 17 through the controller to stop driving the support plate 16 to rotate, so that the counterweight 19 stops driving the water pipe 15 to continue to descend, and then the staff can control the sampling pump 12 to work, so that the sampling pump 12 extracts water from the water body through the connecting pipe 13, the connecting sleeve 14, and the water pipe 15, and then the extracted water is discharged into the interior of one of the water buckets 9, and the water is discharged into the corresponding sampling tank 7 through the water bucket 9. When the water inside the sampling tank 7 reaches a certain weight, the pressure sensor 8 at the bottom of the sampling tank 7 will transmit the signal to On the controller, the controller controls the sampling pump 12 to stop working, and then the controller controls the first motor 4 to work. The first motor 4 drives the limiter 6 to rotate sixty degrees through the rotating shaft 5. The rotation of the limiter 6 will drive the sampling tank 7 filled with water samples to move away, leaving from the top of the pressure sensor 8 and the bottom of the water outlet of the sampling pump 12, so that the empty sampling tank 7 rotates to the top of the pressure sensor 8 and the bottom of the water outlet of the sampling pump 12, waiting for the subsequent sampling of water at different depths and positions in the water body, and the sampling tank 7 filled with water samples will be driven to rotate toward the arc-shaped tooth plate 11, so that the seal 10 on the sampling tank 7 will mesh with the arc-shaped tooth plate 11 and be rotated, and then the seal 10 rotates to seal the opening between the water bucket 9 and the sampling tank 7, so as to prevent the subsequent unmanned boat from shaking on the water body, causing the water sample in the sampling tank 7 to scatter, and even the water in multiple sampling tanks 7 to splash into different sampling tanks 7, causing different water samples to mix with each other, causing problems with the collected water samples;

[0024] It should be noted that when the staff needs to sample water samples at different depths and positions, the staff can control the sampling pump 12 to discharge excess water inside the connecting pipe 13, the connecting sleeve 14, and the water pipe 15 to prevent the remaining water inside the water pipe 15 from mixing with the water in other water layers when water samples at different depths and positions are subsequently extracted, causing sampling problems. Then, the previous steps are repeated to sample water samples at different depths and positions. It should be noted that when the staff needs to take out the water samples collected inside the unmanned boat, the staff can control the unmanned boat to approach the staff, and then the staff can open the cover 2 and take out the water samples from the inside of the limiter 6.

[0025] Embodiment 2: A sampling pump 12 is fixedly installed inside the hull 1, and the water outlet of the sampling pump 12 is arranged at the top of one of the water buckets 9. A connecting pipe 13 is fixedly connected to the outer wall of the sampling pump 12, and a connecting sleeve 14 is fixedly connected to one end of the connecting pipe 13. A water pipe 15 is rotatably connected inside the connecting sleeve 14. For details, see Figure 2 The outer wall of the water pipe 15 is provided with a support plate 16, which is rotatably connected to the inside of the hull 1. A second motor 17 is fixedly installed inside the hull 1, and the support plate 16 is fixedly connected to the outer wall of the output shaft of the second motor 17. Figure 4 One end of the water pipe 15 is fixedly connected to a pressure valve 18 , the outer wall of the water pipe 15 is fixedly connected to a counterweight 19 , the pressure valve 18 is arranged inside the counterweight 19 , and a filter hole 20 is opened on the outer wall of the counterweight 19 .

[0026] It should be noted that, through the setting of the pressure valve 18, when the sampling pump 12 is not working, the pressure valve 18 will seal the water pipe 15 to prevent the water inside the water body from entering the water pipe 15 and mixing with the water samples collected at different depths and positions subsequently, affecting the final water sample detection results. As a result, when the sampling pump 12 is working, it will eventually apply suction to the water pipe 15, so that the suction force will suck open the pressure valve 18 through the water pipe 15, so that the water sample inside the external water body can enter the water pipe 15 and finally be discharged into the sampling tank 7. By opening the filter hole 20 on the counterweight 19, the filter hole 20 can filter the water body and filter out some larger impurities in the water body to prevent the impurities from entering the interior of the sampling pump 12 and causing the sampling pump 12 to get stuck.
