Specific embodiment
The technical solution of the patent is explained in further detail With reference to embodiment:
Embodiment 1
Fig. 1-4, a kind of water quality detection sample collecting device, including movable base plate 1 are please referred to, is equipped with vertically on movable base plate 1 vertical
Column 12,12 top horizontal of column are fixed with cantilever lever 10, and 10 bottom of cantilever lever is fixed with fixed plate 7, and 7 bottom of fixed plate is hinged with
The turning-bar 6 for driving it to turn to by regulating mechanism, 6 lower end of turning-bar are opened up by being hinged with water intaking cylinder 13, water intaking 13 side wall of cylinder
There is inlet tube 21, vertical sliding is sealed and installed with baffle 22 in inlet tube 21, and inlet 28,22 bottom of baffle are offered on baffle 22
Portion is equipped with resetting-mechanism.
Movable base plate 1 in the present apparatus is moved to by the waters to be fetched water, is driven and is turned to by the regulating mechanism of setting
Bar 6 rotates, and then realizes and the water intaking cylinder 13 on turning-bar 6 is extend into inside waters, adopts water sampling to realize.
Specifically, regulating mechanism includes the servo motor II11 for being fixed on 10 bottom of cantilever lever, and servo motor II11's is defeated
Shaft is coaxially fixed with threaded rod 8, and screw thread is connected to thread bush block 9 on threaded rod 8, is hinged between thread bush block 9 and turning-bar 6
Support rod 5.
By above-mentioned setting, servo motor II11 can drive threaded rod 8 to rotate, and threaded rod 8 drives thread bush block 9 thereon
Transverse shifting, thread bush block 9 drive turning-bar 6 to be rotated by support rod 5, thus realize the lifting effect of water intaking cylinder 13,
Water intaking cylinder 13 drops to the water surface or less and fetches water, and the position of 6 lower end of turning-bar can be adjusted, and realizes to different depth
Water layer is fetched water.And during turning to horizontal position when turning-bar 6, water intaking cylinder 13 gradually risen to from water the water surface with
On, left end is finally displaced into close to the position of movable base plate 1, also facilitates the acquisition of operator.
In order to which be able to achieve the specific depth of water adopts water effect, without being mixed into inside water intaking cylinder 13 by the water of other depth, this
Device further comprises resetting-mechanism, specifically includes the open sleeve 25 for the bottom opening being fixed on water intaking cylinder 13, opening set
Sealing sliding is equipped with piston head 26 in cylinder 25, and 26 upper end of piston head is vertically fixed sealing sliding through the piston of open sleeve 25
Bar 23, piston rod 23 are fixed with 22 bottom of baffle, be arranged on piston rod 23 both ends respectively with open sleeve 25 and piston head 26
Fixed reset spring 24.
When original state, the region of non-inlet 28 is corresponding with inlet tube 21 on baffle 22, i.e. baffle 22 is by inlet tube 21
It is obstructed with water intaking cylinder 13, the water in waters cannot enter in water intaking cylinder 13, when water intaking 13 dive of cylinder to the waters of certain depth
When interior, since hydraulic pressure constantly increases, the water in waters has upward extruding force to piston head 26 in open sleeve 25, at this time
Piston head 26 moves up, 24 deformation of reset spring compression, and piston rod 23 drives 22 upward sliding of baffle, the inlet on baffle 22
28 are overlapped with inlet tube 21, enter in water intaking cylinder 13 at this point, the water in waters can pass through inlet 28 along inlet tube 21
Realize water intaking.
Being subsequently diverted to bar 6 drives water intaking cylinder 13 to move up, and the water pressure that piston head 26 is subject to reduces, in reset spring 24
Downward elastic-restoring force effect under, 26 slide downward of piston head, baffle 22 is gradually moved down and is resetted at this time, inlet 28 with
Inlet tube 21 is not overlapped, and realizes again barrier of the baffle 22 to inlet tube 21, avoid the water near nonspecific depth into
Enter into water intaking cylinder 13, the purity for adopting water sampling of certain depth is higher, greatly improves the accuracy of sampling.It samples simultaneously
To water energy in time be enclosed in water intaking cylinder 13 inside, not will cause and spill.
Embodiment 2
In order to slide the adjusting of required hydraulic pressure pressure to piston head 26, realizes that different depth adopts the accuracy of water, implementing
On the basis of example 1, it is fixed with bracket 19 on cylinder 13 of fetching water, screw thread, which wears to be connected with, on bracket 19 adjusts stud 18, adjusts stud
18 lower ends, which abut, pressing plate 20, and preloading spring 17 is vertically fixed between pressing plate 20 and baffle 22.
By above-mentioned setting, pressing plate 20 can be carried out to realize that preloading spring 17 is initial to moving by adjusting stud 18 by rotation
The adjusting of elastic force is pre-tightened, i.e., when 17 compression degree of preloading spring is higher, when 22 upward sliding of baffle, is acted on piston head 26
Required water pressure is bigger, i.e., when water intaking 13 dive of cylinder to deeper waters position, is just able to achieve baffle 22 with respect to inlet tube 21
Upward sliding is connected to inlet 28 with inlet tube 21, adopts water effect to realize.Conversely, when 17 compression degree of preloading spring is got over
Low, the depth that water intaking cylinder 13 can adopt water is more shallow.
In addition, being fixed with screw thread male connector 15 in water intaking 13 top vertical of cylinder, it is threadedly coupled and is arranged with admittedly in screw thread male connector 15
It is scheduled on the screw thread female 14 of 16 bottom of sunpender, 16 upper end of sunpender is hinged on 6 lower-left end of turning-bar.Cylinder 13 of fetching water passes through screw thread male connector
15 with the connection for being threadedly engaged realization Yu sunpender 16 of screw thread female 14, the installation and removal of water intaking cylinder 13 are simple and convenient.
For the balance for guaranteeing water intaking cylinder 13, prevent it from shaking, it is fixed on side wall of the cylinder 13 far from inlet tube 21 of fetching water
There is balance weight 27, lead or the biggish material of iron block isodensity can be selected in balance weight 27, to promote the weight of water intaking cylinder 13, is convenient for
Its dive.
In order to expand the region of water intaking, column 12 is articulated on movable base plate 1, and movable base plate 1 is equipped with for driving
The steering mechanism that column 12 rotates, steering mechanism includes the servo motor I2 being fixed on movable base plate 1, and servo motor I2's is defeated
Shaft is coaxially fixed with worm screw 4, and the worm gear 3 for being fixed with and engaging with worm screw 4 is arranged on column 12.
By above-mentioned setting, when servo motor I2 drives worm screw 4 to rotate, worm gear 3 is rotated with it, and column 12 is with snail
3 rotation of wheel, to realize that the steering of cantilever lever 10 is adjusted, it can be achieved that cylinder 13 of fetching water to be turned to the different location in waters, significantly
The range of sampling water intaking is improved, convenient for carrying out adopting water sampling in a big way.
In conclusion the present invention is adjusted by the depth that the regulating mechanism being arranged can use the progress of water drum 13 dive to waters
Section, realizes the water intaking movement of different water depth, and the resetting-mechanism being arranged realizes water intaking cylinder 13 drop to after certain depth just can be real
Water sampling effect is adopted in the connection of existing inlet 28 and water intaking cylinder 13 and inlet tube 21, realization, when water intaking cylinder 13 leaves water intaking region
Afterwards, baffle 22 can block in time inlet tube 21, and the water for avoiding other depth water layers enters in water intaking cylinder 13, realize spy
Depthkeeping degree adopts water sampling effect.
