step three: the well is still for more than twenty-four hours after the well is washed, a water taking pipe is a copper pipe 9, the diameter is 45mm, the length is 1m, 1.5L of water can be taken at one time, a winding and unwinding device 2 is fixed at the top end of a hollow pipe 1 at the top end through a connecting device 5 before water is taken, when an induction probe 10 touches the water surface, an indicator lamp 4 on a well head box 3 gives an alarm to prompt the user to reach the water surface, a connecting rope 12 is slowly put through the winding and unwinding device 2 at the moment, the copper pipe 9 slowly sinks under the action of self weight, two unidirectional water inlet devices 7 which can freely turn upwards are connected at the center of a counterweight metal block 8, the unidirectional water inlet devices 7 can be opened upwards under the action of water pressure, the copper pipe 9 can continuously sink until the copper pipe is filled with water along with the increase of the weight of the underground water, then the copper pipe 9 is lifted upwards, and the unidirectional water inlet devices 7 at the bottom of the water taking pipe can be automatically closed under the action of water gravity, therefore, the underground water is collected, and finally, the water is poured out from the water outlet on the upper left of the copper pipe 9.
The working process is as follows: all electrical appliances in the device are external power supplies, when the device is used, a drilling machine is used for drilling a drill bit 13 into the ground to form a well, after the drill bit 13 is drilled below the water level, a hollow pipe 1 is placed, the hollow pipe 1 is kept in the middle of a drill hole, sand and stones are uniformly backfilled into the drill hole at the periphery of the hollow pipe 1 after installation is finished, then according to the field environment, a drilling machine is adopted as a hole forming machine, a DPP100-4E type automobile drilling machine is adopted, a threaded drill bit 13 with the diameter of 240mm is installed on the hollow pipe 1, during installation, the connecting part of the drill bit 13 is connected with the hollow pipe 1 at the bottom end through a connecting mechanism, then the drill bit 13 fixed with a connecting block 602 to be used is inserted into a fixed sleeve 601, then a second threaded shaft 608 is rotated, when a rack 607 is meshed with a fixed gear 603 on the outer side of the connecting block 602, a supporting block 605 continuously compresses a second spring 606, because the maximum torque forces which can be borne by different drill bits 13 are different, when the scale value of the rotating handle of the second threaded shaft 608 on the dial 609 just reaches the maximum torque force range which can be borne by the drill bit 13, the second threaded shaft 608 stops rotating, at the moment, the gear 603 continuously slips when the drill bit 13 reaches the maximum torque force and is not clamped with the rack 607, so that the drill bit 13 is well protected, the phenomenon that the drill bit 13 is broken and deformed is avoided, after the drill bit 13 drills below the water level, the drill bit 13 at the bottom end of the PVC hollow tube 1 at the bottom end is detached, the PVC hollow tube 1 is inserted into a drill hole to collect underground deep water, the maximum depth can drill to 70m, and the requirement of underground water collection in a large-thickness loess plateau area can be met; the hollow pipes 1 can be connected through a connecting mechanism, when the drill bit 13 is detached, the drill bit 13 can be detached only by pulling the bottom end pull rod 504 to compress the first spring 505 at the bottom end, so that the fixture block 503 at the bottom end is disengaged from the lower sleeve 501 at the bottom end, at the moment, the upper sleeve 502 at the bottom end is separated from the lower sleeve 501 at the bottom end, the biggest difficulty in collecting water samples in a large-thickness loess area is that after the drill bit 13 is drilled below the water level, loess below the underground water level is in a soft plastic or flow plastic state due to long-time water soaking, if the wall protection is not carried out timely, the underground water samples cannot be collected, and therefore, the PVC hollow pipe 1 with the diameter of 160mm is processed, and water taking failure caused by necking is prevented; in order to ensure the quality and accuracy of water taking, the well forming depth should be 10-20 m below the water level in principle, so that five diagonal cross holes 14 are arranged at the end part of the PVC hollow pipe 1 below the water level to facilitate the smooth flow of underground water into the pipe, the well washing is carried out immediately after the well forming, a deep well submersible pump 220V stainless steel pump with a lift of 70m is adopted for the well washing, the diameter of the pump is 10cm, a generator is self-provided, the well washing is carried out until the water is clear, no silt is taken as a standard, the well washing is stopped for more than 24 hours after the well washing is finished, a water taking pipe is a copper pipe 9 with the diameter of 45mm and the length of 1m, 1.5L of water can be taken at one time, before the water is taken, a collecting and releasing mechanism is positioned at the top end of the hollow pipe 1 at the top end through a connecting mechanism, then a first threaded shaft 203 is rotated anticlockwise, at the moment, the connecting frame 202 drives a left rubber wheel 204 to move leftwards, and then a connecting rope 12 is placed between the two rubber wheels 204, finally, the rubber wheel 204 on the left side is reset, after the operations are completed, the control motor 208 drives the driving gear 207 and the driven gear 206 to be positively and reversely meshed, so that the rubber wheel 204 can be driven to rotate positively and reversely under the driving of the fixed shaft 205, the copper pipe 9 is driven to move up and down through the friction between the rubber wheel 204 and the connecting rope 12, the labor intensity of workers is reduced, when the copper pipe 9 moves down to take water, when the induction probe 10 touches the water surface, the indicator lamp 4 on the wellhead box 3 gives an alarm to prompt the arrival at the water surface, the motor 208 slowly rotates, so that the connecting rope 12 is slowly controlled to move down, the copper pipe 9 slowly sinks under the action of self weight, because the center of the counterweight metal block 8 is connected with two unidirectional water inlet mechanisms which can freely turn upwards, under the action of water pressure, the piston 702 continuously compresses the third spring 703, so that the water inlet at the bottom end of the water inlet pipe 701 is opened, water this moment can enter into copper pipe 9 through inlet tube 701 in, along with groundwater constantly gets into copper pipe 9, copper pipe 9 weight gain can continue to sink until filling up water, then control motor 208 reversal is upwards lifted up copper pipe 9, and the one-way mechanism of intaking of copper pipe 9 bottom is under the action of water gravity, and piston 702 can automatic re-setting close to gather groundwater, at last from the left water outlet department in copper pipe 9 top pour out the water of taking out can.
