The electronic three-way valve B311, the electronic three-way valve C312 and the electronic three-way valve D313 are all fixedly provided with a shunt pipe 314 connected to the sample collecting bottle A36, the sample collecting bottle B37, the sample collecting bottle C38 and the sample collecting bottle D39; the adjustment component is arranged on the base 1 for adjusting the position of the sampling head 34, the adjustment component 4 includes a pillar 41, a rotating groove is opened on the top of the pillar 41, a rotating shaft is rotatably arranged inside the rotating groove, a fixing nut A42 is fixedly arranged at one end of the rotating shaft, a connecting plate is fixedly arranged on the rotating shaft, an electric telescopic rod 43 is fixedly arranged on the connecting plate, and an electric A guide roller 44 is rotatably provided at the end of the telescopic rod 43, and a limit rod is fixedly provided on one side of the guide roller 44. The volume of the sample collecting bottle D39 is greater than the sum of the volumes of the sample collecting bottles A36, B37 and C38. Limit blocks are fixedly provided on both sides of the collecting plate, and a limit groove matching the limit block is provided inside the sample storage cavity. The inner wall of the sampling head 34 is filled with lead blocks, and a filter screen 8 is fixedly provided at the end of the sampling head 34. The filter screen 8 is used to block impurities in the water to prevent impurities from entering the water pump 31, thereby increasing its service life.

[0027] The water flow collected by the water pump 31 is transported to the sample collecting bottle A36, the sample collecting bottle B37, the sample collecting bottle C38 and the sample collecting bottle D39 through the electronic three-way valve A310, the electronic three-way valve B311, the electronic three-way valve C312 and the electronic three-way valve D313 on the sample transport tube 35, so as to realize the collection of water samples at different water levels in the water source, thereby improving the collection efficiency.

[0028] Figure 1-2 A second embodiment is shown, which mainly differs from the first embodiment in that a box door 5 is rotatably provided on the front of the sampling box 2, a turntable 6 is rotatably provided on the sampling box 2 located at the position of the winding roller 33, a handle 7 is fixedly provided on the turntable 6, a non-slip rubber pad is fixedly provided on the handle 7, the turntable 6 is fixedly connected to the winding roller 33, a fixing nut B is provided on the turntable 6, and a plurality of sets of moving wheels 9 are fixedly provided at the bottom of the base 1.

[0029] The device can be moved by the moving wheels 9 under the base 1, thereby improving its convenience. At the same time, the position of the electric telescopic rod 43 can be rotated by the rotating shaft above the pillar 41, so that it can be placed on the top of the sampling box 2, reducing the long-term support of the pillar 41 on the electric telescopic rod 43, thereby increasing its service life.

[0030] Meanwhile, the contents not described in detail in this specification belong to the prior art known to those skilled in the art, and the model parameters of each electrical appliance are not specifically limited, and conventional equipment can be used.

[0031] When in use, the sampling head 34 is driven by the electric telescopic rod 43 to move to the top of the required sampling water source, and then the sampling head 34 drives the sampling tube 32 to move under its own weight until it sinks to the required sampling water level, and the position of the sampling head 34 is fixed by the fixing nut on the turntable 6, and then the water source of the adopted water level is transported to the sample delivery tube 35 through the sampling tube 32 by the water pump 31, and at the same time, the electronic three-way valve A310 is opened, and the electronic three-way valve B311, the electronic three-way valve C312 and the electronic three-way valve D313 are closed, so that the water flow is transported to the sample collection bottle A36 through the diversion tube 314. When the sample collection bottle A36 is collected, the water pump 31 stops working, the electronic valve A is closed, and then the handle 7 on the turntable 6 drives the winding roller 33 to rotate, so that the sampling head 34 is driven to rise through sampling. When it rises to the middle water level, the position of the sampling head 34 is fixed by the fixing nut B, and the water source is transported to the sample delivery tube 35 by the water pump 31, and at the same time, the electronic valve D is opened. Thus, the water flow of the lower water level remaining in the sample delivery tube 35 is transported to the sampling bottle D through the shunt tube 314. After several seconds, the electronic valve D is closed and the electronic valve B is opened, so that the water flow passes through the shunt tube 314 on the electronic valve B and is transported to the sampling bottle B. When the water flow in the sampling bottle B is collected, the water pump 31 is closed, and the fixing nut B is rotated to release the limit on the position of the sampling head 34. At the same time, the turntable 6 is rotated to drive the sampling head 34 to move upward to the upper water level through the sampling tube 32, and the position of the sampling head 34 is fixed by the fixing nut B. Then the water pump 31 starts the electronic valve D to open synchronously, so that the water flow remaining in the sample delivery tube 35 is transported to the sampling bottle D. After several seconds, the electronic valve D is closed and the electronic valve C is opened, so that the water flow is transported to the sampling bottle C. When the sampling bottle C is collected, the electronic valve C is closed and the electronic valve D is opened, so that the water flow at the upper water level is transported to the sampling bottle D, thereby realizing the collection of different water levels and the collection of the entire water source.
