[0029] In the utility model, the floating plate 1 provides buoyancy for the entire device when it floats on the water surface. The plug rod 14 is inserted into the plug groove 15 so that the plugged movable back plate 19 will not shake left and right to affect the docking of the bottle stopper 11 and the sampling bottle 10. The fixing bolt 13 is inserted into the positioning hole 16 of the upper and lower plates and the nut 12 is rotated to clamp the upper and lower plates to make the connection between the plates more secure. The sampling bottle 10 can be installed and disassembled by combining the threaded groove and the threaded column 18 at the bottom of the sampling bottle 10, which is convenient for transferring and storing the samples after the collection is completed. The movable plate 24 below can be driven to move by moving the slider 8, thereby driving the bottle stopper 11 plugged on the plug block 20 to move, so as to realize the opening or closing of the bottle mouth of the sampling bottle 10. Example

[0030] Reference Figure 1-Figure 5, which is basically the same as Example 1, and further, the movable back plate 19 and the movable plate 24 can be connected in multiple groups, a plurality of springs 22 are fixed on the movable plate 24, and the other end of the spring 22 is connected to a circular push plate 23, and the push plate 23 is sleeved on the plug-in block 20, and a limiting groove 25 is provided on the bottle stopper 11 and the plug-in block 20, and a thread is provided in the limiting groove 25 on the plug-in block 20, and a plug-in bolt 17 threadedly connected to the limiting groove 25 is provided on the limiting groove 25, and a baffle 3 and a bottom plate 5 are fixed on both sides of the upper end surface of the floating plate 1, and a driving part 4 is fixed on the baffle 3, and a threaded rod 7 is connected to the output end of the driving part 4, and the other end of the threaded rod 7 is connected to the bottom plate 5, and a slider 8 is sleeved on the threaded rod 7, and a limiting plate 6 fixed to the floating plate 1 is provided on both sides of the slider 8.

[0031] In the present invention, the sampling personnel can determine the number of movable back plates 19 and movable plates 24 to be assembled according to the sampling depth and sampling points required, so as to flexibly cope with different sampling requirements and sampling environments.

[0032] The push plate 23 slides on the plug block 20. When the movable plate 24 is pushed forward, the push plate 23 also acts on the bottle stopper 11. When the push rod 21 pushes the bottle stopper 11 to block the bottle mouth of the sampling bottle 10, the spring 22 is in a compressed state, so that it can continuously generate thrust on the bottle stopper 11 to avoid a gap between the bottle stopper 11 and the bottle mouth of the sampling bottle 10 due to external reasons such as shaking, which may cause the collected sample to be contaminated.

[0033] The plug bolt 17 can be inserted into the limit groove 25 on the bottle plug 11 to fix the bottle plug 11 to prevent the bottle plug 11 from being washed away by the water flow when collecting in water. The plug bolt 17 is installed and fixed through the thread in the limit groove 25 on the plug block 20.

[0034] The collector can remotely control the driving unit 4 to rotate the threaded rod 7 to make the slider 8 reciprocate. The slider 8 is connected to the movable plate 24 below, thereby driving the bottle stopper 11 below to move and open or close the mouth of the sampling bottle 10.

[0035] The limit plates 6 at both ends of the slider 8 limit the slider 8 to prevent the slider 8 from rotating along with the threaded rod 7 , and the slide groove 9 provides movement space for the connection between the slider 8 and the fixed back plate 2 below.

[0036] The baffle 3 is used to fix the driving part 4 to prevent the driving part 4 from contacting the water surface and damaging the internal parts of the driving part 4. The bottom plate 5 is used to support the threaded rod 7 to prevent the threaded rod 7 from sinking due to weight, causing the bottle stopper 11 below to be misaligned with the bottle mouth of the sampling bottle 10.

[0037] When in use, the user splices the movable plate 24 and the movable back plate 19 in advance according to the number and depth of samples to be collected. After the splicing is completed, the sampling bottle 10 is installed on the corresponding threaded column 18, the bottle plug 11 is plugged into the corresponding plug block 20 and positioned and fixed by installing the plug bolt 17, and then the driving unit 4 is started to make the bottle plug 11 plug the bottle mouth of the sampling bottle 10, and the nuclear device can be placed on the water surface. When the device stops, the driving unit 4 can be controlled to drive the bottle plug 11 away from the sampling bottle 10, and the sampling bottle 10 can sample the water quality at the corresponding point. After the sampling is completed, the driving unit 4 can be controlled to make the slider 8 drive the bottle plug 11 to plug the bottle mouth of the sampling bottle 10 and retract the device. After the device is retracted, the user only needs to remove the plug bolt 17 and remove the sampling bottle 10 from the threaded column 18 to obtain a complete sample.

[0038] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
