When the elasticity of the coil spring is released, the measuring frame is driven to rotate. When the push block slides inwards to one side close to the axis, the clamping block can be pushed out of the clamping groove, and meanwhile, the clamping block cannot enter the clamping groove; the upper control mechanism is used for simultaneously pushing the adjacent push blocks to one side close to the axis so that the clamping block can cross the clamping grooves corresponding to the corresponding push blocks when being separated from the clamping grooves; the lower control mechanism is used for changing the push blocks of the upper control mechanism acting on different positions when the measuring frame slides downwards along the measuring column, so that the clamping block entering the clamping groove again is pushed out. The angle of rotation of the measuring frame is smaller, so that the single water collection amount of the sampling assembly is less, and when the measuring group descends more, the single water collection amount of the sampling assembly is more, so that the device can sample at different water depths, and the water collection amount of the sampling assembly is more uniform for different water layers at each time.

The measuring column 460 is vertically disposed for measuring the depth of water deep into the water. The measuring stand 120 is slidably and rotatably provided on the measuring post 460 in an up-and-down direction, and is initially positioned to be flush with the horizontal surface, so that the measuring stand 120 descends along the measuring post 460 when the lower end of the measuring post 460 is in contact with the water bottom. The survey pole 460 is first lowered with respect to the survey frame 120, and when the lower end of the survey pole 460 is in contact with the water bottom, the survey frame 120 slides down along the survey pole 460.
The sampling component 260 is arranged below the measuring rack 120, so that the sampling component 260 rotates to extract a water sample from the measuring rack 120, the water sampling amount of the sampling component 260 is in positive correlation with the rotation angle of the measuring rack 120, the larger the rotation angle of the measuring rack 120 is, and the larger the water sampling amount of the sampling component 260 is. The first adjustment assembly is within the measurement stand 120 and includes a coil spring 150 and an adjustment ring 140. The coil spring 150 is slidably sleeved on the measuring column 460 up and down, the initial state of the coil spring 150 is in an initial contraction force storage state, the coil spring 150 is connected with the measuring frame 120 so as to drive the measuring frame 120 to rotate when the elastic force of the coil spring 150 is released, and a sliding block is fixedly arranged on the axis column of the coil spring 150, so that the coil spring 150 can be slidably arranged on the measuring column 460 up and down. One end of the coil spring 150, which is far away from the axis, is provided with a fixture block 152, the outer end edge of the coil spring 150 is provided with the fixture block 152, and the fixture block 152 rotates counterclockwise around the measuring column 460 under the driving of the elastic force release of the coil spring 150. The adjusting ring 140 is slidably disposed on the measuring post 460 and on the coil spring 150, and the adjusting ring 140 is slidably disposed on the measuring post 460 only. A plurality of slots are uniformly distributed on the circumferential wall of the adjusting ring 140, and the slots penetrate through the circumferential wall of the adjusting ring 140 along the radial direction of the adjusting ring 140. The latch 152 can be inserted into the slot, so that when the latch 152 is inserted into the slot, the coil spring 150 is in a state of non-releasing power.
The slots penetrate through the circumferential wall of the adjusting ring 140 along the radial direction, a pushing block 290 is slidably disposed in each slot, so that when the pushing block 290 slides inward on one side close to the axis, the pushing block 152 can be pushed out of the slot, and meanwhile, the pushing block 152 cannot enter the slot, the pushing block 290 and the slot are connected with an elastic member, so that when the pushing block 290 moves inward under the pushing force, the elastic member accumulates force, and when the pushing force disappears, the pushing block 290 returns to the initial state. When the pushing block 290 pushes the block out of the slot, the inner side surface of the pushing block 290 and the inner wall of the adjusting ring 140 are in the same plane, the fixture block 152 is separated from one slot and rotates counterclockwise along the inner wall of the adjusting ring 140, and meanwhile, the fixture block 152 cannot be inserted into one slot where the pushing block 290 slides inward until entering the next slot where the pushing block 290 does not slide inward. The more the adjacent pushing blocks 290 are not moved inward, the larger the angle of the fixture block 152 rotating along the inner wall of the adjusting ring 140 away from the fixture groove is, and the larger the angle of the measurement rack 120 rotating is driven to be increased.
The control mechanism comprises an upper control mechanism and a lower control mechanism. The upper control mechanism is used for simultaneously pushing out a plurality of adjacent pushing blocks 290 to one side close to the axis, so that the fixture block 152 can cross over the corresponding fixture slot of the plurality of pushing blocks 290 when being separated from the fixture slot. The lower control mechanism is used for changing the pushing block 290 acting on different positions of the upper control mechanism when the measuring rack 120 slides downwards along the measuring column 460, so that the fixture block 152 entering the fixture groove again is pushed out, specifically, when the fixture block 152 rotates for a certain angle along the adjusting ring 140 and is inserted into one fixture groove again, the position of the pushing block 290 acting on the upper control mechanism is changed, the number of the pushing blocks 152 is unchanged, and the pushing block 152 is pushed out from the fixture groove again by the pushing block 290.
The second adjustment assembly is configured such that the distance that the measuring column 460 moves downward relative to the measuring rack 120 is inversely related to the number of pushers 290 that the upper control mechanism can push out, such that the more the measuring column 460 is lowered, the fewer pushers 290 the upper control mechanism can push out, and thus the less water per sampling of the sampling assembly 260. The more water is collected in a single time by the sampling mechanism.
In this embodiment, as shown in fig. 2 to 6, the upper control assembly includes an upper telescoping rod 160 and a pushing ring 130.

Each of the ejector blocks 270 corresponds to one of the push blocks 290, so that when the ejector block 270 extends inward out of the ejector groove and the ejector ring 130 slides upward relative to the adjusting ring 140 by a predetermined distance, the ejector block 270 pushes the push block 290, and specifically, when the lower end of the push block 290 is provided with an inclined surface, so that when the ejector block 270 contacts the inclined surface of the push block 290, the ejector block 270 moves upward along the inclined surface of the push block 290 and pushes the push block 290 inward. Go up telescopic link 160 and be the arcuation and be telescopic structure, the radian of telescopic link 160 is 360 on the initial condition, and the suit is on ejection ring 130 for extrude ejector pad 270 inwards, so that ejector pad 270 stretches out the top and pushes away the groove to one side of keeping away from the axle center, go up telescopic link 160 initial condition and exert inside thrust with whole ejector pad 270, along with the shrink of last telescopic link 160, make the thrust on the ejector pad 270 withdraw one by one. Particularly, the outer end surface of the top block 270 is an inclined surface, so that when the upper telescopic rod 160 is restored to the initial state, the top block 270 is conveniently restored to the initial state again. The second adjusting component is configured to measure the distance that the column 460 moves downwards relative to the measuring rack 120 and the contracted length of the upper telescopic rod 160 to be in positive correlation, and simultaneously drive the push ring 130 to rotate by a preset angle.
