In the figure: the device comprises a lifting system 1, a connector 2, a water inlet joint 3, a steel pipe standard joint 4, a straight joint 5, a one-way valve 6, a bracket 7, a fixed pulley 8, a rope 9, a power source 10, a steel pipe clamp 11, a hole 12, water 13, a first cross beam 14, a second cross beam 15 and a taper pin 16.
Detailed Description
As shown in figure 1, the water sample collecting device with different depths in the hole comprises a lifting system 1, wherein the lifting system 1 comprises a support 7, and the support 7 is arranged at the upper end of a hole 12. The top end of the bracket 7 is provided with a fixed pulley 8, one end of the rope 9 which bypasses the fixed pulley 8 is connected with the connector 2, and the other end is connected with a power source 10. The power source 10 may be a winch or a chain block.
The upper end of the connecting head 2 is provided with a lug plate with holes, the lower end of the connecting head is provided with external threads, and the connecting head 2 is in threaded connection with the water inlet joint 3 through a straight joint 5. The water inlet joint 3 comprises a steel pipe standard joint 4, the steel pipe standard joint 4 is a hollow steel pipe, the upper part and the lower part of the steel pipe are both threaded to form a threaded interface, and the adjacent steel pipe standard joints 4 are in threaded connection through a straight joint 5. The straight joint 5 here is a threaded sleeve with a threaded inner bore. The unique serial number (1, 2 … N) is coded on the outer wall of the steel pipe standard knot 4, and the lowest end of the first steel pipe standard knot 4 is connected with the one-way first knot valve 6 to form a water sample inlet knot 3.
There is also a steel pipe clamp 11 for fixing into the water section 3 during removal or installation. The concrete structure of the steel pipe clamp 11 comprises a first beam 14 and a second beam 15, wherein the first beam 14 and the second beam 15 are spliced through a taper pin 16, a hole is formed in the center of the spliced first beam 14 and the spliced second beam 15, and the hole can allow a standard section 4 of a steel pipe to pass through and limit a straight joint 5.
The working principle and the process are as follows:
installation: arranging a lifting system 1, connecting a connector 2 with the lifting system 1, connecting a steel pipe standard joint 4 with a one-way valve 6 in a threaded manner to form a water inlet joint 3, and connecting the water inlet joint 3 with the connector 2 through a straight connector 5. The lift system 1 is activated to extend the check valve 6 to the planned depth of water intake in the bore. After the one-way valve 6 enters the water to a certain depth, the one-way valve 6 is automatically opened due to the water pressure, and the water sample flows into the steel pipe.
Before each section of steel pipe standard joint 4 is lengthened, the steel pipe fixture 11 is used for fixing the water inlet joint 3 in the hole 12 at the orifice, then the connector 2 is separated from the water inlet joint 3 in the hole, and then the new steel pipe standard joint 4 sleeved with the straight joint 5 is respectively connected with the connector 2 and the water inlet joint 3 in the hole.
Sampling: after the water inlet joint 3 extends into water, the one-way valve 6 is opened by the pressure of the water, so that a water sample enters the steel pipe. After the planned water sample enters the steel pipe, the water inlet joint 3 is lifted by the lifting system 1, and the one-way valve 6 is automatically closed to prevent the water sample from flowing outwards.
Disassembling: after taking the water sample, will go into water festival 3 and wholly promote, check valve 6 will self-closing this moment, and the water sample no longer outflows. After the water sample is lifted to the ground, the water sample is poured into a water sample collecting bottle. According to the collection plan, the water samples of corresponding degree of depth are adorned in the collection bottle of difference when dismantling the steel pipe to reach the purpose of gathering the different degree of depth water samples.
When each standard knot 4 is disassembled, the steel pipe is integrally lifted to the uppermost standard knot 4 and is positioned above the ground. Then, the steel pipe fixture 11 is used for fixing the water inlet joint 3 in the hole at the hole opening, then the steel pipe standard joint 4 on the ground is disassembled, and the lower end of the disassembled standard joint 4 can be artificially plugged in order to reduce the outflow of water in the standard joint 4 after the disassembly until the water is transferred into the water sample collecting bottle.
The device is successfully applied to water sample collection of underground water erosion test of an Angola Kykah hydropower station project and is well verified in experimental analysis. The device is suitable for underground water sampling in various environments, and is particularly suitable for water sample collection work with small aperture and large depth.
