[0022] The classification mechanism 2 includes a first septum 201, a second septum 202, a first water inlet 203, a second water inlet 204, a third water inlet 205, a first water pipe 206, a second water pipe 207, a first through hole 208, a second through hole 209, a first water outlet 210, a second water outlet 211, a third water outlet 212 and a cap 213. The first septum 201 is fixedly connected to one side of the sampling bottle 1, the second septum 202 is fixedly connected to one side of the sampling bottle 1, the first water inlet 203 is opened at one end of the sampling bottle 1, the second water inlet 204 is opened at one end of the sampling bottle 1, the third water inlet 205 is opened at one end of the sampling bottle 1, the first septum 201 is fixedly connected to the first water pipe 206, and the second septum 202 is fixedly connected to the second water pipe 207.

A cap 213 is threadedly connected to the surface of one side of the first water outlet 210. During use, when samples of different depths or different areas need to be collected, the three independent spaces formed by the first septum 201 and the second septum 202 can be used for storage. When taking out the samples, it is only necessary to open the caps 213 on the first water outlet 210, the second water outlet 211 and the third water outlet 212 in turn, and then take out the samples in turn.

[0023] Furthermore, the second water inlet 204 is connected to the first through hole 208 through the first water pipe 206, and the third water inlet 205 is connected to the second through hole 209 through the second water pipe 207. By setting the second water inlet 204, the first water pipe 206, and the first through hole 208, the water source to be collected will not seep into the sample storage space where the first water inlet 203 is located, thereby avoiding mutual penetration between samples and making the detection results more accurate. By setting the third water inlet 205, the second water pipe 207, and the second through hole 209, the water source to be collected will not seep into the sample storage space where the second water inlet 204 is located, thereby avoiding mutual penetration between samples and ensuring the accuracy of the detection results.
[0024] Furthermore, there are three groups of caps 213, the second water outlet 211 is threadedly connected to the cap 213, and the third water outlet 212 is threadedly connected to the cap 213. Through the arrangement of three groups of caps 213, the first water outlet 210, the second water outlet 211, and the third water outlet 212, samples of each level can be taken out in sequence, thereby increasing the collection efficiency.
[0025] Furthermore, the switch mechanism 3 includes a plug 301, a water stop groove 302, a first limit block 303, a second limit block 304, a waterproof rubber ring 305, a transmission shaft 306, a rotating block 307, a first connecting column 308, a line 309, a second connecting column 310, a hanging ring 311, a hook 312, a fixing block 313, a fixing ring 314, a support rod 315, a first sliding groove 316, a second sliding groove 317, a third sliding groove 318 and a connecting block 319, one side of the surface of the first water inlet 203 is engaged with the plug 301, one side of the plug 301 is provided with a water stop groove 302, one end surface of the sampling bottle 1 is fixedly connected to the first limit block 303, the inner end of the sampling bottle 1 is fixedly connected to the second limit block 304, and the water stop groove 302 A waterproof rubber ring 305 is fixedly connected to the surface of the plug 301, a transmission shaft 306 is fixedly connected to one end of the surface of the plug 301, a rotating block 307 is rotatably connected to one side of the transmission shaft 306, one end of the rotating block 307 is fixedly connected to a first connecting column 308, the other end of the first connecting column 308 is fixedly connected to a line 309, the other end of the line 309 is fixedly connected to a second connecting column 310, the other end of the second connecting column 310 is fixedly connected to a hanging ring 311, a hook 312 is movably sleeved on the surface of one side of the hanging ring 311, one end of the hook 312 is fixedly connected to a fixed block 313, one side of the fixed block 313 is fixedly connected to a fixed ring 314, the interior of the fixed ring 314 is penetrated by a support rod 315, and the interior of the support rod 315 is provided with a first sliding The support rod 315 is provided with a second sliding groove 317, a third sliding groove 318 is provided inside the support rod 315, and the other end of the support rod 315 is fixedly connected with a connecting block 319. Here, the first water inlet 203 is taken as an example. During use, when it is necessary to collect samples at a specified position or depth, the hanging ring 311 can be manually pulled, and the pulling of the hanging ring 311 will drive the line 309 to slide in the first sliding groove 316. At the same time, the line 309 will drive the first connecting column 308 to move, and the movement of the first connecting column 308 will drive the rotating block 307 to move, and the movement of the rotating block 307 will drive the transmission shaft 306 to move, and the movement of the transmission shaft 306 will drive the plug 301 at the first water inlet 203. When the surface is flipped, the sample water source will enter the storage space in the sampling bottle 1 along the first water inlet 203, thereby achieving the effect of opening the first water inlet 203 to collect the sample water source. When the collection is completed, it is only necessary to place the hanging ring 311 on the hook 312, and the plug 301 will flip due to its own gravity. At the same time, due to the action of the first limit block 303 and the second limit block 304, the plug 301 will completely close the first water inlet 203, thereby achieving the effect of stopping sampling. When it is necessary to change the position or depth, at this time, it is only necessary to directly move the sampling bottle 1 to the specified position or depth, and then find the hanging rings 311 corresponding to the second water inlet 204 and the third water inlet 205 in turn, and operate according to the method of operating the first water inlet 203.There is no need to lift the sampling bottle 1 again, and the sampling work can still be completed underwater.
[0026] Furthermore, the number of stoppers 301 is three groups, and the number of lines 309 is three groups. Through the three groups of stoppers 301, the sampling bottle 1 can collect samples at different positions or different depths. Through the setting of three groups of lines 309, the lines 309 can control the stoppers 301 in sequence, thereby improving the sampling efficiency.
[0027] Furthermore, the surface of the first sliding groove 316 is slidably connected to the line 309, the surface of the second sliding groove 317 is slidably connected to the line 309, and the surface of the third sliding groove 318 is slidably connected to the line 309. Through the setting of the first sliding groove 316, the second sliding groove 317, the third sliding groove 318 and the line 309, the movement of the lines will not interfere with each other, thereby improving the sampling efficiency.
[0028] Working principle: During use, when it is necessary to collect samples at a specified position or depth, the hanging ring 311 can be manually pulled, and the plug 301 can be turned over on the surface of the first water inlet 203, and the sample water source will enter the storage space in the sampling bottle 1 along the first water inlet 203, thereby opening the first water inlet 203 to collect the sample water source. When the collection is completed, it is only necessary to place the hanging ring 311 on the hook 312. When it is necessary to change the position or depth, it is only necessary to directly move the sampling bottle 1 to the specified position or depth, and then find the second water inlet 204, the third water inlet 204 in turn. The hanging ring 311 corresponding to 5 can be operated in the same way as the first water inlet 203. There is no need to lift the sampling bottle 1 again, and the sampling work can still be completed underwater. When it is necessary to collect samples at different depths or in different areas, the three independent spaces formed by the first diaphragm 201 and the second diaphragm 202 can be used for storage. When taking out the samples, it is only necessary to open the caps 213 on the first water outlet 210, the second water outlet 211 and the third water outlet 212 in turn, and then take out the samples in turn. After taking out the samples, the caps 213 can be manually tightened, which greatly improves the sampling efficiency.
