Abstract
The utility model relates to a deep-water fixed depth sampling device, which belongs to sampling equipment for collecting deep-water water samples. The deep-water fixed depth sampling device has the technical scheme that the upper end and the lower end of a water storage device are respectively connected with a valve which is controlled to be automatically opened and closed by water pressure and is used for controlling the flowing direction of the water to obtain the fixed depth water samples, the outer side of the valve is connected with a conical protective cover lined with a filter screen, and the conical protective cover is used for preventing impurities from entering the sampling device and ensuring the smooth passing of the whole body of the sampling device under the condition of bulge obstacle existence. The deep-water fixed depth sampling device is mainly applicable to water sample sampling in deep wells, particularly the deep-well sampling of the small-caliber sleeve-pipe-free wall protection device, the depth can be freely selected according to the requirement, the operation is simple, the cost is low, the practicability is strong, and the popularization and the application are convenient.
Description
Technical field
The utility model relates to a kind of sampling equipment that is used to gather water sample, and particularly the small diameter deep well depthkeeping is gathered the sampling equipment of water sample.
Background technology
Environmental protection and other relevant departments carry out water quality or hydroplankton etc. when analyzing, and need the water sample of required depths be gathered, and also cry the depthkeeping water sampling.The water sample of depthkeeping collection will be got rid of the interference of other degree of depth water layers just need isolate taking-up to institute's water sampling.The method that depthkeeping is gathered water sample in the prior art mainly contains two kinds, and a kind of is to adopt small pump to carry out depthkeeping to draw water and obtain water sample; Another kind is to adopt container to transfer to predetermined depth to take a sample.The drawback of first method is that sampling depth is limited and cost is higher, and the at present main problem that exists of second method is that the unreasonable and equipment profile of sampling equipment sealing and size design can't be carried out the depthkeeping sampling to small-bore drilling well etc.
Summary of the invention
The technical problems to be solved in the utility model provides a kind of sampling equipment that can carry out the depthkeeping water sampling to small-bore drilling well.
The technical scheme that its technical matters that solves the utility model adopts is:
Deep water depthkeeping sampler; comprise water receiver; described water receiver below is connected with into water one-way cock; described water inlet one-way cock below is provided with the conical protective cover of water inlet, and the conical protective cover of described water inlet lower end is provided with suspension ring, and described suspension ring lower end is connected with weight; described water receiver top is connected with the water outlet one-way cock; described water outlet one-way cock top is provided with the conical protective cover of water delivering orifice, and the conical protective cover of described water delivering orifice upper end is provided with suspension ring, and described suspension ring link to each other with ropes.
Described unidirectional inlet valve inside is provided with the hydraulic pressure unidirectional water inlet piston of control automatically, is used for the control water inlet, prevents seepage.
Described unidirectional flowing water Valve inside is provided with hydraulic pressure automatically control is unidirectional and goes out water piston, is used to control water outlet, anti-backflow.
The conical protective cover of described water inlet inside is provided with the foreign material screen pack.
The conical protective cover of described water delivering orifice inside is provided with the foreign material screen pack.
The beneficial effect that the utility model produced is: carry out in the process of water sampling in not carrying out the small-bore naked hole drill well of sleeve pipe panelling construction, unidirectional water inlet and flowing water Valve can be because the pressure of current open and close automatically, the interference of isolated effectively other water layers obtains the water sample of predetermined depth.In addition, the taper protective cover at two ends can make sampler pass through the obstruction trouble-free operation of projection barrier up and down, thereby netted foreign material screen pack can stop larger particles in the water to enter effectively to be avoided causing one-way cock to close situation not in place occurring.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is the contour structures synoptic diagram of a kind of embodiment of deep water sampling device of the present utility model;
Fig. 2 is the vertical view of one-way cock of the present utility model;
Fig. 3 is the cross sectional representation of the one-way cock of this utility model;
Fig. 4 is the fundamental diagram of the deep water sampling device of this utility model.
Among the figure: 1. lifting rope, 2. suspension ring, 3. water delivering orifice foreign material screen pack; 4. water delivering orifice, 5. one-way cock, the 6. conical protective cover of water delivering orifice; 7. water receiver; 8. hydraulic pressure is controlled one-way piston automatically, 9. conical protective cover, 10. water inlet of water inlet; 11. water inlet foreign material screen pack; 12. pin, 13. sealing draw-in grooves, 14. weights.
Embodiment
As shown in Figure 1; deep water sampling device of the present utility model comprises water receiver 7; the bottom of water receiver 7 is water inlet one-way cock 5; connect the conical protective cover 9 of water inlet in the bottom of water inlet one-way cock 5; be provided with water inlet 10 above the conical protective cover 9 of water inlet; the inside of water inlet 10 is lined with water inlet foreign material screen pack 11, and the conical protective cover of water inlet 9 lower ends are provided with suspension ring 2, are used for linking to each other with weight 14.
As shown in Figure 2, be provided with circular hydraulic pressure in the one-way cock 5 and control one-way piston 8 automatically, hydraulic pressure is controlled one-way piston 8 automatically and can be opened and closed automatically under the control of hydraulic pressure pressure differential.
As shown in Figure 3, one-way cock 5 is provided with pin, controls one-way piston 8 opening and closing flexibly automatically to guarantee hydraulic pressure, and hydraulic pressure is controlled one-way piston 8 automatically and is provided with sealing draw-in groove 13, is used to ensure the water receiver good seal, prevents seepage.
As shown in Figure 4, the principle of work of deep water sampling device of the present utility model is: during sampling, with lifting rope 1 sampler is transferred to predetermined depth, in transferring process, because the action of gravity of weight, sampler has certain decline rate, make sampler and extraneous water generation relative motion, extraneous water enters water inlet one-way cock 5 by water inlet 10, larger-size foreign material by 11 interceptions of water inlet foreign material screen pack outside, the pressure of the mobile generation of water forces water inlet one-way piston 8 to be opened automatically, current enter water receiver 7 smoothly, current arrive top water delivering orifice one-way cock 5 by water receiver 7, and the pressure of the mobile generation of water forces water delivering orifice one-way piston 8 to be opened automatically, and current flow out smoothly by water delivering orifice 4 then.When reaching predetermined depth, the sampler stop motion, water receiver 7 internal and external pressure balances, one-way piston 8 is closed under the deadweight effect automatically, the water sample of being gathered is sealed in the water receiver 7, pulling rope 1 is upwards put forward sampler, this moment sampler and extraneous water generation relative motion, water delivering orifice one-way piston 8 on the 7 top water delivering orifice one-way cocks 5 of water receiver under the effect of water flow pressure is closed tightly, also closed tightly under the action of gravity of the water inlet one-way piston institute's water sample in water receiver 7 on the water receiver 7 lower water inlet one-way cocks 5, promote sampler to the face of land this moment, and water sample collection work is finished.
