Specific embodiment
Below with reference to attached drawing, the present invention is described in detail:
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.
By the improvement of above structure, the depth bounds that can be fetched water as needed, the piston switch 2 of water intaking cylinder 1 selects to close
Simultaneously accurate initial compression amount is arranged by precession bolt 11 in suitable compressed spring 13, under natural conditions, due to upper piston block 14
Thickness be greater than inlet opening 15 diameter, upper piston block 14 is blocked between inlet opening 15 and apopore 10 at this time, water intaking cylinder 1
In sinking watching, hydraulic pressure suffered by lower piston block 17 is gradually increased, and pushes upper piston block 14 by connecting column 16, specified when reaching
When depth of fetching water, upper piston block 14 goes just past 15 bottom end sideline of inlet opening, and continues to move up in the water intaking depth bounds, makes
The channel that obtaining water sample can be flowed through between upper piston block 14 and lower piston block 17 by inlet opening 15 enters apopore 10, hence into
It fetches water in cylinder 1, air is discharged by escape pipe 3 in cylinder, water intaking is completed, until moving on to apopore 10 and water inlet on lower piston block 17
When between hole 15, water stream channel blocking, piston switch 2 is in closed state, realizes water intaking in certain depth bounds.
Pouring weight 6 is installed in the lower end of the water intaking cylinder 1, upper end is equipped with the cover center connection ring that can connect traction rope
5.In this way convenient for the sink-float of control water intaking cylinder 1, multiple designated depth water sampling devices can also be selected to connect by rope as needed, be assembled into
Multiple spot designated depth water sampling device.
Unidirectional elastomeric ball valve 4 is also equipped on the upper surface of the water intaking cylinder 1.The unidirectional elastomeric ball valve 4 is mounted on
The open end of escape pipe 3 only allows fluid to be flowed outward by escape pipe 3, and in the case where cylinder 1 of fetching water submerges in water, this is unidirectional
Elastomeric ball valve 4 is closed in the presence of hydraulic pressure, prevents the water of non-sampling water layer from entering in water intaking cylinder 1.
Offer sliding slot 9 on the piston wall 8 of the piston switch 2, the side of the upper piston block 14 be provided with
The protrusion that the sliding slot 9 is slidably matched.The length of the sliding slot is at the completely plugged inlet opening of lower piston block, and the protrusion is just
It is against well on the top cell wall of sliding slot.In this way, on the one hand can prevent piston block from rotating so that compressed spring 13 deforms, on the other hand
Compel compressed spring prevented also from 14 excessive pressure of upper piston block, plays the role of limit.
The position disk 12 is that two disk compositions, the compressed spring 13 up and down being hinged are connected on lower disk,
The end of precession bolt 11 is against on disk, and the other end of the precession bolt 11 runs through the top plate 7 of piston switch 2, described
Precession bolt 11 is used to adjust the precompressed tightness of compressed spring 13.In this way, can make compressed spring 13 that can oneself in stress
By rotating, the concentricity of compressed spring 13 and piston switch 2 is kept, stress change of sensitivity caused by deforming is prevented, makes to fetch water
Range is more accurate.
Beneficial effects of the present invention: device for fetching water is only in specifically water intaking depth bounds water intaking, good leak tightness, not by lifting speed
Spend the influence of mutation, it is ensured that the accuracy of sampling；One people can be operated, and structure is simple, easy to disassemble, be easy to carry about with one；It is not required to use
Electricity is not necessarily to cable, without danger of hazardous electrical discharges；Water intaking is completed, and device for fetching water can be used repeatedly after cleaning out, economize on resources, subtract
Few cost.
The above examples are only used to illustrate the technical scheme of the present invention and are not limiting, although referring to preferred embodiment to this hair
It is bright to be described in detail, those skilled in the art should understand that, it can modify to technical solution of the present invention
Or equivalent replacement should all cover without departing from the objective and range of technical solution of the present invention in claim of the invention
In range.
