A supporting structure 3 is provided on the surface of the carrier 202. By setting the supporting structure 3, the sealed layered water sample collection device can be supported on the ground, making it convenient for the staff to pour out the water sample in the collection box 211.

[0029] The specific settings and functions of the sampling structure 2 and the supporting structure 3 are described in detail below.

[0030] Reference Figure 2 、 Figure 4 and Figure 5 As shown, in this embodiment: the sampling structure 2 includes a limiting rod 212, the surface of the limiting rod 212 is fixedly connected to the circular plate 1, and a collection box 211 is fixedly installed on the end of the limiting rod 212 away from the circular plate 1. A plurality of circular holes 209 are evenly opened on the surface of the collection box 211, and a plurality of storage spaces are evenly arranged inside the collection box 211. A sealing sleeve 206 is slidingly sleeved on the surface of the collection box 211, and a connecting ring 210 is fixedly installed on the surface of the sealing sleeve 206. A supporting frame 202 is fixedly installed on the surface of the circular plate 1, and the supporting frame 202 slides through the circular plate 1. The surface of the circular plate 1 is rotatably connected to the positioning frame 203, and the surface of the positioning frame 203 is slidably connected to the supporting frame 202. The positioning frame 203 can fix the circular plate 1 and the supporting frame 202. Two balancing frames 204 are fixedly connected to the surface of the circular plate 1. The surfaces of the two balancing frames 204 are fixedly installed with grip plates 205. Two balancing rods 208 are fixedly inserted into the interior of the connecting ring 210. The two balancing rods 208 are fixedly installed with a connecting frame 207 at one end away from the fixing ring. The surface of the connecting frame 207 is fixedly connected to the sealing sleeve 206. A brush is provided on the surface of the connecting frame 207. The brush on the connecting frame 207 can remove debris near the circular hole 209 so that the debris will not block the circular hole 209. An air bag 201 is fixedly installed on the surface of the circular plate 1. The air bag 201 can make the circular plate 1 float on the water.

[0031] Reference Figure 3 As shown, specifically, the support structure 3 includes two elastic sleeves 32, the surfaces of the two elastic sleeves 32 are fixedly connected to the carrier frame 202, the surfaces of the elastic sleeves 32 are rotatably sleeved with support blocks 31, the surfaces of the two support blocks 31 are fixedly installed with clamping plates 33, and the surface of the connecting ring 210 is fixedly installed with two support frames 34, the surfaces of the support frames 34 are in contact with the clamping plates 33, and the support frames 34 and the clamping plates 33 can assist the support blocks 31 in supporting the carrier frame 202.

[0032] Working principle: when it is necessary to collect water samples at different levels at the same location, first put the sampling structure 2 underwater, then fix the circular plate 1 with the help of the grip plate 205 and the balance frame 204, and then rotate the positioning frame 203. After the positioning frame 203 rotates to a certain angle, the surface of the positioning frame 203 is no longer in contact with the carrier frame 202, and then slide the carrier frame 202 upward. When the carrier frame 202 slides, it drives the connecting ring 210 to slide. When the connecting ring 210 slides, it drives the sealing sleeve 206 to slide. After the sealing sleeve 206 slides a certain distance, the surface of the sealing sleeve 206 no longer blocks the circular hole 209 on the collection box 211. At this time, the water sample enters the collection box 211 along the circular hole 209. After collecting the water sample, slide the carrier frame 202 downward. The carrier frame 202 When sliding, it drives the connecting ring 210 to slide, and when the connecting ring 210 slides, it drives the sealing sleeve 206 to slide. After the sealing sleeve 206 slides a certain distance, the surface of the sealing sleeve 206 blocks the circular hole 209 on the collection box 211, so that the water sample in the collection box 211 will not flow out. During this process, the sealing sleeve 206 will drive the connecting frame 207 to slide. When the connecting frame 207 slides, the brush on the connecting frame 207 will remove the debris near the circular hole 209. In this way, when sampling, the staff only needs to collect once to collect water samples of different layers required at the same position. By setting the sampling structure 2, when collecting water samples from the surface of the water body, water samples of different layers required at the same position can be collected, so that the data collected by the water sample can be more accurate.

[0033] When the water sample in the collection box 211 needs to be poured out, the layered water sample sealing collection device is first placed horizontally, and then the support block 31 is rotated. After the support block 31 is rotated to a certain angle, the card plate 33 on the support block 31 contacts the card plate 33. At this time, the support block 31 is fixed by the elastic sleeve 32 using elastic force. At this time, the support block 31 can support the layered water sample sealing collection device, so that the layered water sample sealing collection device cannot rotate, thereby making it convenient for the staff to pour out the water sample in the collection box 211. By setting the support structure 3, the layered water sample sealing collection device can be supported on the ground, making it convenient for the staff to pour out the water sample in the collection box 211.

Those skilled in the art will understand the specific meanings of the above terms in this utility model based on specific circumstances.
