Example 2:

the present embodiment is different from embodiment 1 in that the annular slider 10 is disposed at a different position and the annular slider 5 is driven in a different manner.

Referring to fig. 5, an annular slide block 5 is arranged outside a sampling bottle 2, the inner side wall of the annular slide block 5 abuts against the outer side wall of the sampling bottle 2, a sealing gasket is arranged inside the annular slide block 5, a plurality of lifting pieces 7 are circumferentially arranged on the sampling bottle 2, the lifting pieces 7 drive the annular slide block 5, the lifting pieces 7 select waterproof electric cylinders, and the waterproof electric cylinders drive the annular slide block 5 to slide to close and seal a water inlet 4; the sampling bottle 2 is fixedly provided with a waterproof cover 8, the waterproof cover 8 covers the outer side of the lifting piece 7, and the waterproof cover 8 can reduce the probability of impact of sundries on the waterproof electric cylinder and can further play a waterproof role; the sampling bottle 2 is close to top department and sets up the sensor, and behind liquid level contact sensor, sensor drive lifting 7 makes annular slider 5 seal inlet opening 4.

The implementation principle of the embodiment 2 is as follows: the bottle cap 202 is installed on the bottle body 201, then the sampling bottle 2 is fixed on the aircraft 1 through the rotating rope 33, the aircraft 1 is moved to a lake or a middle section of a water source, the driving piece 34 is started to enable the rotating roller 32 to rotate, the sampling bottle 2 is made to sink into water, a water sample enters the sampling bottle 2 through the water inlet 4, the annular sliding block 5 is driven to gradually seal the water inlet 4, when the water sample is sufficiently collected, the lifting piece 7 is driven by the water sample contact sensor to drive the lifting piece 7, the lifting piece 7 enables the annular sliding block 5 to slide, the annular sliding block 5 completely seals the water inlet 4, then the rotating roller 32 is driven to rotate, the sampling bottle 2 is made to be separated from the lake, then the sampling bottle 2 is made to return through the aircraft 1, then the adjusting rod 14 is shifted to detach the bottle cap 202, the sampling bottle 2 is.

The above embodiments are preferred embodiments of the present application, and the protection scope of the present application is not limited by the above embodiments, so: all equivalent changes made according to the structure, shape and principle of the present application shall be covered by the protection scope of the present application.
