After the fixing step is completed, the user cancels fixing of the sliding shells 6 distributed at equal intervals, the sliding shells 6 distributed at equal intervals and the sampling block 7 are downwards moved to the river surface under the influence of gravity, then the user drives away from the river channel by taking a ship, after the state in the river channel is recovered, the user injects air into the upper side elastic bag 9 through the air pump, simultaneously, the user injects water into the lower side elastic bag 9 through the water pump, along with the gradual increase of water in the lower side elastic bag 9, the lowest sliding shell 6 is downwards moved gradually, the lowest sliding shell 6 drives the middle three sliding shells 6 and the sampling block 7 to downwards move through the scissor type expansion frame 10, the distance between every two adjacent sliding shells 6 is always equal, then the lowest sliding shell 6 is moved to the bottom part of the river channel, the user stops injecting water into the lower side elastic bag 9 through the water pump, at the moment, the five sliding shells 6 are uniformly distributed at different heights in the river channel, then the sampling step is carried out, the states of the elastic bags 9 are respectively changed, the buoyancy and the gravity are utilized to uniformly divide the sliding shells 6 distributed at different levels in the river channel, the same height level, the same time, the same amount of sample is guaranteed between different levels, the different levels are adapted to different levels, the same level sample level ratio is guaranteed, and the sample level ratio is improved.
When river water in a river channel is sampled, because the flow rates are different between different levels of the river channel and the biological communities and microorganism distributions are also different between different levels, in order to ensure that samples have referential property, the river water of different levels needs to be sampled for multiple times, while the prior sampling technology is only single sampling with fixed depth, in order to ensure the comparability between different levels, the sampling base (namely the total amount of flowing river water) between different levels needs to be kept consistent, and in addition, because the flow rates of the river water between different levels are different, the sampling frequency of the sliding shell 6 between different levels also needs to be synchronously changed, so that the following operations are needed to solve the problems:
in the process that the lowermost slide housing 6 gradually moves downwards, the slide housing 6 drives the adjacent first rotating rod 1203 to move downwards, the first rotating rod 1203 drives the adjacent spur gear 1208 to move downwards, the spur gear 1208 drives the adjacent third slide frame 1209 to move downwards, as the lowermost third slide frame 1209 gradually moves downwards, the rear end of the third slide frame 1209 contacts and presses to the upper inclined surface of the second limiting block 1212, the lowermost third slide frame 1209 is pressed by the upper inclined surface of the second limiting block 1212 to gradually move leftwards, the lowermost third slide frame 1209 drives the adjacent spur gear 1208 and the fourth slide frame 1211 to move leftwards, meanwhile, the spring between the fourth slide frame 1211 and the second fixed frame 1210 is pressed, the fourth slide frame 1211 drives the upper four third slide frames 1209 to synchronously move leftwards, the third slide frames 1209 distributed equidistantly drive the adjacent spur gears 1208 to move leftwards until the lowermost slide housing 6 moves downwards to the limit, at this time, all the gears 1208 are engaged with the gears on the output shaft of the adjacent gear box 1201, and all the slide housings 6 are moved to the sampling positions.
When all the straight gears 1208 are meshed with the gears on the output shafts of the adjacent gearboxes 1201, taking one gearbox 1201 as an example, the river water flows to drive the turbofan 1202 to rotate, the turbofan 1202 drives the gearbox 1201 to rotate the input shaft, the gearbox 1201 output shaft is meshed with the straight gears 1208 through the upper gears thereof to drive the first rotating rod 1203 to rotate, the first rotating rod 1203 drives the gear deficiency 1204 to rotate, the gear deficiency 1204 also gradually rotates along with the continuous flow of river water until the first part of teeth on the gear deficiency 1204 are meshed with the gears on the second rotating rod 1205, the gear deficiency 1204 drives the second rotating rod 1205 to rotate through the meshing with the gears on the second rotating rod 1205, the bevel gear on the second rotating rod 1205 is meshed with the bevel gear ring 1206 and drives the sampling block 7 to rotate until the first part of teeth on the gear deficiency 1204 are out of mesh with the gears on the second rotating rod 1205, at this time, the sampling block 7 rotates 45 DEG, one of the sampling chambers in the sampling block 7 rotates to be communicated with the through hole on the sliding shell 6 and the through hole on the sealing ring 1207, because the volume of the sampling chamber in the sampling block 7 gradually decreases from outside to inside, river water flows to the inside of the sampling chamber through the outside of the sampling chamber in the sampling block 7, air in the sampling chamber is extruded to be discharged outwards through the through hole on the sealing ring 1207, as the gear-lack 1204 continues to rotate, a second part of teeth on the gear-lack 1204 are meshed with the gear on the second rotating rod 1205 and drive the second rotating rod 1205 to rotate, the second rotating rod 1205 drives the sampling block 7 to rotate 45 DEG again through the meshing of the bevel gear and the bevel ring 1206 thereon, at this time, the sampling chamber after sampling is no longer communicated with the outside, the next sampling chamber to be sampled rotates to a position 45 DEG from the through hole on the sliding shell 6, then the river water is sampled after the same amount of step intervals are repeated, the river flow rate among different levels in the river channel is monitored through the turbofan 1202, so that the sampling state of the sampling block 7 is controlled and regulated, the sampling block is used for equally dividing and sampling the same river total amount, the sampling base numbers and the sampling amounts of the sampling blocks 7 distributed at equal intervals are equal, and the sample comparability among different levels is ensured.
After all the four sampling cavities on the sampling block 7 are sampled, the user pumps out water in the lower elastic bag 9, after the water is pumped out, the user pumps quantitative gas into the lower elastic bag 9 through the air pump, the buoyancy of the lower elastic bag 9 gradually increases along with the gradual increase of the gas in the lower elastic bag 9, the lower elastic bag 9 drives the bottommost sliding shell 6 to move upwards, the bottommost sliding shell 6 drives the upper three sliding shells 6 to move upwards through the scissor type telescopic frame 10 until the lower elastic bag 9 floats out of the water, at the moment, the user takes a ship to the vicinity of the five sliding shells 6 and takes out samples one by one, after the sample is taken out, the user controls the air pump to discharge air in the two elastic bags 9, and then the user resets and fixes the five sliding shells 6, at the moment, the sampling work is completed.
In the process of moving up the lowermost slide housing 6, the slide housing 6 drives the third slide frame 1209 to move up through the adjacent first rotating rod 1203 and the spur gear 1208, along with the gradual upward movement of the lowermost third slide frame 1209, the second limiting block 1212 gradually loses the limit on the lowermost third slide frame 1209, the spring between the fourth slide frame 1211 and the second fixed frame 1210 drives the second fixed frame 1210 to move rightward and reset, the second fixed frame 1210 drives all the third slide frames 1209 to move rightward and reset, and the adjacent spur gear 1208 of the third slide frame 1209 moves rightward and resets, so that the spur gear 1208 loses the engagement with the gear on the output shaft of the adjacent gearbox 1201, and the reset is completed at this time.
