[0021] Depend on Figures 1 to 4It is given that a traction rope 17 is provided on one side of the mobile control component 2, and a cable 18 is provided inside the traction rope 17, which is inserted into the outer cylinder 4 and electrically connected to the controller 16. The mobile control component 2 is composed of a float 19, a plurality of small thrusters 20, a solar panel 21, a handle 22 and a connecting ring 23. The float 19 is fixedly connected to the top of the outer cylinder 4, the small thruster 20 is fixedly connected to the side of the float 19, the solar panel 21 and the handle 22 are both fixedly connected to the top of the float 19, the connecting ring 23 is fixedly connected to one side of the float 19 and fixedly connected to one end of the traction rope 17, the small thruster 20 and the solar panel 21 are both electrically connected to the controller 16, the counterweight water inlet pipe 8 is provided with a solenoid valve 1 24, the sampling water inlet pipe 9 is provided with a solenoid valve 25, and the sampling drainage pipe 13 is provided with a valve 26, and the solenoid valve 1 24 and the solenoid valve 25 are both electrically connected to the controller 16;
[0022] The sampler is placed in the water, connected to the connecting ring 23 through the traction rope 17, and the cable 18 is connected to the controller 16. The sampler is powered and controlled through the cable 18. When water does not enter the counterweight chamber 6 and the sampling chamber 7, the gravity of the sampler is the same as the buoyancy of the float 19. Therefore, the entire sampler floats on the water surface, and the small propeller 20 is started. The small propeller 20 pushes the entire sampler to move in the water. When it moves to the specified position, the solenoid valve 24 on the counterweight water inlet pipe 8 is opened, and water enters the counterweight chamber 6 through the counterweight water inlet pipe 8, and the water entering the counterweight chamber 6 is controlled.

At the same time, the micro water pump 11 is started to perform sampling through the sampling water inlet pipe 9, so that water enters the interior of the sampling chamber 7, and the water inside the counterweight chamber 6 is discharged through the micro water pump 11, thereby preventing the sampler from sinking. After the sampling is completed, the solenoid valve 25 and the micro water pump 11 are closed, and the sampler can be pulled back by the traction rope 17. The sampler is retrieved, and then the valve 26 is opened to discharge the water into the specified container through the sampling drain pipe 13.
[0023] During operation, by setting up a mobile control component composed of a float, several small thrusters, a solar panel, a handle and a connecting ring, the entire sampler can be pushed to move in the water, so that water at different positions can be sampled. The solar panel can use solar energy for auxiliary charging. By setting up a traction rope, the sampler can be prevented from being lost, thereby improving the safety of use. By setting up an outer cylinder, an inner cylinder, a counterweight chamber, a sampling chamber, a counterweight water inlet pipe, a sampling water inlet pipe, a counterweight drain pipe and a sampling drain pipe, the sampler can be lifted and lowered by controlling the water inlet and drain, thereby sampling water at different depths, thereby improving the practicability of the sampler.
