Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings.
Referring to fig. 1 and 2, for the utility model discloses a small-bore well drilling layering water sample sampler, including cylindrical sampling bottle 1, the bottleneck internal diameter of sampling bottle 1 is less than its body internal diameter. The top of sampling bottle 1 is provided with handle 2, and handle 2 is "Jiong" font along the cross-section of vertical direction, and its top surface middle part has been tied up first rope 3 and has seted up the round hole on its surface, and the metal pull rod 4 that has vertical setting runs through in the round hole, and the top welding of pull rod 4 has the link, has tied up second rope 6 on the link, and in this embodiment, first rope 3 and second rope 6 adopt different colours to make, are convenient for observe, and are equipped with scale mark 11 on it. The bottom of pull rod 4 is corresponding and is provided with bottle plug 5 with the bottleneck, and the diameter of bottle plug 5 is greater than the aperture of round hole, and the bottom of sampling bottle 1 is provided with drain pipe 7, is equipped with the stagnant water on the drain pipe 7 and presss from both sides 8. During sampling, the bottle stopper 5 is firstly ensured to seal the bottle mouth, the water stop clamp 8 is used for clamping the liquid outlet pipe 7, and after the situation that no error exists is confirmed, the sampling bottle 1 is slowly placed into a drilling well through the first rope 3. Observe scale mark 11, when sampling bottle 1 arrived appointed sample water layer, with the help of the pressure of water to sampling bottle 1, pulling second rope 6 makes bottle plug 5 extract, and liquid gets into in sampling bottle 1 this moment until filling whole sampling bottle 1. Subsequently, the second rope 6 is pulled, the sampling bottle 1 is taken out from the drilled well, and the sample detection can be carried out through the liquid outlet pipe 7. It is thus clear that the utility model has the advantages of easy operation, high practicality.
Referring to fig. 2 and 3, if the bottle stopper 5 is fixed too tightly to the mouth of the sampling bottle 1, the second rope 6 is pulled, and the bottle stopper 5 may not be pulled out, so that, as an optimization, a conical weight 12 with a downward tip is detachably connected to the bottom surface of the sampling bottle 1, a groove 13 is formed in the bottom surface of the sampling bottle 1, a first hook 14 is integrally formed in the groove 13, and a second hook 15 matched with the first hook 14 is integrally formed on the top surface of the weight 12. The arrangement of the heavy hammer 12 enables the bottle stopper 5 to be subjected to larger tension, so that the bottle stopper 5 is convenient to separate from the bottle opening, and meanwhile, the conical heavy hammer 12 is also more beneficial to the sampling bottle 1 to enter a water layer of a drilled well, so that the sampling time is shortened.
Referring to fig. 2, after sampling, in the process of lifting the sampling bottle 1 out of the well, sample liquid of different liquid layers may be mixed with the sample liquid in the bottle due to bumping, and detection results may be affected. Therefore, a hollow floating ball 9 made of rubber is arranged in the sampling bottle 1, the diameter of the floating ball 9 is larger than the inner diameter of the bottle mouth, when the sampler continuously enters the sample liquid, the floating ball 9 floats in the sampling bottle 1, and when the top end of the floating ball is completely attached to the bottom of the bottle mouth, other sample liquid is prevented from continuously entering. Furthermore, a connecting line 10 is connected between the floating ball 9 and the bottle stopper 5 in a hot melting mode, the length of the connecting line 10 is larger than the height of the bottle opening, and the distance between the bottle stopper 5 and the top surface of the lifting handle 2 is larger than the height of the connecting line 10. After sampling is finished, the second rope 6 is pulled, the floating ball 9 is completely attached to and abutted against the bottom of the bottle opening, the sealing effect of the floating ball 9 on the bottle opening is further improved, and sample liquid of different liquid layers is prevented from being mixed with sample liquid in the bottle; in addition, the setting up of connecting wire 10 makes the in-process that the sampling bottle 1 advanced appearance liquid, stimulates second rope 6 at any time, can make floater 9 plug up the bottleneck, stops advancing kind, has realized the effect of ration sample, very big reinforcing the practicality of this sampler.
Referring to fig. 1 and 2, when the sample liquid is detected, the sampling bottle 1 needs to be cleaned, but the pull rod 4 and the handle 2 affect the cleaning operation, so the following optimization is made: the bottom end of the handle 2 is rotatably connected with the sampling bottle 1, and the pull rod 4 comprises a first fixing rod 41 and a second fixing rod 42 which are connected through threads. When the sampling bottle 1 needs to be cleaned, the pull rod 4 can be rotated, so that the first fixing rod 41 and the second fixing rod 42 are separated, the pull rod 4 is conveniently taken down from the upper part of the handle 2, and the handle 2 is rotated to avoid the bottle mouth.
The implementation principle of the embodiment is as follows: during sampling, the bottle stopper 5 is used for slightly sealing the bottle mouth, the water stop clamp 8 is used for clamping the liquid outlet pipe 7, and then the heavy hammer 12 is fixed on the sampling bottle 1 through the first hook 14 and the second hook 15. After the fixing, the sampling bottle 1 is slowly placed into the borehole by means of the first cable 3, without pulling the second cable 6 in the process. And observing the scale mark 11, and when the sampling bottle 1 reaches a specified sampling water layer, pulling the second rope 6 to pull out the bottle stopper 5 to start sampling. After removal, the weight 12 is removed, and the pull rod 4 is rotated to separate the first fixing rod 41 and the second fixing rod 42, and then the sample bottle 1 is removed. Subsequently, place sampling bottle 1 level and transport to the detection center, during the detection, open water-stop clamp 8, take out the appearance liquid through drain pipe 7.
The embodiment of this specific implementation mode is the preferred embodiment of the present invention, not limit according to this the utility model discloses a protection scope, so: all equivalent changes made according to the structure, shape and principle of the utility model are covered within the protection scope of the utility model.
