A base block 113 is fixed to the outer wall of the bottom of the outer cylindrical shell 111, and a movable clamping rod 114 is rotatably mounted on the base block 113.

[0026] The inner shell component 12 is disposed inside the outer shell component 11 and is used to cooperate with the outer shell component 11 to perform stratified water intake control.

[0027] In this embodiment, the inner shell assembly 12 includes an inner cylindrical shell 121 rotatably mounted on the inner wall of the outer cylindrical shell 111 , and a strip-shaped opening 122 is provided on the outer surface of the inner cylindrical shell 121 .

[0028] In this embodiment, a threaded cover 123 is screwed onto the inner wall of the top of the inner cylindrical shell 121, and a screw bar 124 is fixed to the upper end of the threaded cover 123. A crossbar 125 is fixed to the bottom side of the inner cylindrical shell 121. A rotating rod 126 that penetrates the bottom wall of the outer cylindrical shell 111 and rotates freely is fixed to the lower end of the crossbar 125.

A plurality of groups of groove bars 128 are arranged in an array around the disk 127, and the groove bars 128 are provided with a slot for the movable clamping rod 114 to match and engage with. By rotating the rotating rod 126, the inner cylindrical shell 121 is driven to rotate, thereby adjusting the relative positions of the strip-shaped openings 122 and the block-shaped openings 112. Since the number of block-shaped openings 112 and groove-shaped strips 128 is consistent, the water flow of a specific layer can enter the inner cylindrical shell 121 through the overlapping openings by rotation, and when a groove-shaped strip 128 on the disc 127 is engaged with the movable clamping rod 114, the inner cylindrical shell 121 stops rotating, and the water sample of this layer is retained in the inner cylindrical shell 121.

[0029] In this embodiment, a mounting plate 3 is fixed to the connecting rod 2 on the side away from the sampler 1, and a pH detector 4 is installed on the upper part of the mounting plate 3, and both the mounting plate 3 and the pH detector 4 are provided with Velcro 5 and are bonded together.

The inner cylindrical shell 121 is driven to rotate by rotating the rotating rod 126, thereby adjusting the relative position of the strip-type openings 122 and the block-type openings 112. Since the number of block-type openings 112 and groove-type strips 128 is consistent, a specific layer of water can be rotated to enter the interior of the inner cylindrical shell 121 through the overlapping openings, and when a groove-type strip 128 on the disc 127 is engaged with the movable clamping rod 114, the inner cylindrical shell 121 stops rotating, and the water sample of this layer is retained in the inner cylindrical shell 121.

[0033] A disc 127 is fixed to the middle section of the rotating rod 126, and a grooved bar 128 is provided on the disc 127.
