Specific embodiment
The utility model is described in detail below with reference to attached drawing:
It is as shown in Figs 1-4:
A kind of designated depth water sampling device, including water intaking cylinder 1 and the piston switch 2 being mounted on water intaking 1 side wall of cylinder, the work
Inlet opening 15 and apopore 10 are provided on plug switch 2, the apopore 10 is communicated with water intaking cylinder 1；The piston switch 2 is bottom
The hollow cylinder structure of portion's opening, is slidably matched in the piston switch 2 and is provided with upper piston block 14 and lower piston block 17, institute
It states and is connected between upper piston block 14 and lower piston block 17 by connecting column 16, the diameter of the connecting column 16 is less than upper piston block 14
Diameter, make upper piston block 14 and lower piston block 17 can be with synchronous slide；Pressure is installed in the upper surface of the upper piston block 14
Contracting spring 13, the other end of the compressed spring 13 is connected in can be described along the position disk 12 that 2 inner wall of piston switch slides
The other end of position disk 12 is against the end of precession bolt 11；The thickness of the upper piston block 14 and lower piston block 17 is big
Diameter in inlet opening 15, the inlet opening 15 is identical as 10 diameter of apopore and is coaxially disposed, the axis of the inlet opening 15
It is vertical with the axis of piston switch 2；Escape pipe 3 is provided on the upper surface of the water intaking cylinder 1.
