Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments.

Referring to fig. 1-2, the groundwater sampling device for geological exploration comprises a collecting cylinder 1, wherein the bottom of the collecting cylinder 1 is arranged in a conical shape; the three closing plate 3 of the inner wall fixedly connected with of collection section of thick bamboo 1, three closing plate 3 will gather section of thick bamboo 1 and cut apart into four and collect the chamber, and four are collected the chamber and all run through collection section of thick bamboo 1 and are provided with two relative first through-holes 4, and first through-hole 4 is located the upper end setting of collecting the chamber, so can collect more groundwater.

The outer part of the collecting cylinder 1 is sleeved with an outer cylinder 2 which is connected with the collecting cylinder in a sliding way, the center of the upper end of the outer cylinder 2 is fixedly connected with a pull rope 7, and the pull rope 7 is connected with external power equipment; be equipped with four stop gear between urceolus 2 and the collection section of thick bamboo 1, stop gear is including setting up spacing groove 8 on the outer wall of a collection section of thick bamboo 1, and sliding connection has sliding block 9 in the spacing groove 8, sliding block 9 and the inner wall fixed connection of urceolus 2 to guarantee that urceolus 2 can not separate with a collection section of thick bamboo 1.

The inner top of the outer cylinder 2 and the upper end of the collecting cylinder 1 are fixedly connected with a spring 5, and eight second through holes 6 opposite to the eight first through holes 4 penetrate through the outer cylinder 2.

Go through on the urceolus 2 and be equipped with cell body 10, be equipped with four drain pipes 11 in the cell body 10, four drain pipes 11 are linked together with four collection chambeies respectively, all install valve 12 on four drain pipes 11, and the groundwater that conveniently will gather through drain pipe 11 is discharged.

When the utility model is used, the pull rope 7 is connected with external power equipment, so that the collecting cylinder 1 and the outer cylinder 2 move downwards, the collecting cylinder 1 moves downwards under the gravity of the collecting cylinder 1, and the first through hole 4 is positioned at the lower side of the second through hole 6 at the moment, as shown in figure 1; when the collecting cylinder 1 and the outer cylinder 2 move downwards and enter underground water, the collecting cylinder 1 is subjected to buoyancy force at the moment, so that the tension force applied to the spring 5 is gradually reduced, the collecting cylinder 1 can move upwards under the action of the spring 5, namely, the first through hole 4 and the second through hole 6 are close to each other, when the collecting cylinder 1 and the outer cylinder 2 completely enter the water, the first through hole 4 and the second through hole 6 are just opposite, so that the underground water can enter a collecting cavity through the first through hole 4 and the second through hole 6, and the underground water with different water layers can be collected by arranging four collecting cavities which are arranged up and down;

after several minutes, the pull rope 7 is pulled upwards to be separated from the underground water, and moves downwards under the gravity of the collecting cylinder 1 and the underground water, at the moment, the spring 5 is stretched, and the first through hole 4 and the second through hole 6 are not opposite to each other, so that the collected underground water cannot leak out;

then, the valves 12 are opened to discharge the groundwater in the four collecting cavities through the drainage pipes 11, which is convenient and simple.
