[0002] A groundwater sampler is a tool used to extract groundwater for technicians to test the groundwater. Currently, samplers on the market usually use a rope to tie a sampling bottle, and the sampling bottle is lowered into the groundwater through the rope for collection.

The double-position pulling and winding measuring assembly is used to release and rewind the multi-point sampling storage assembly by double-point pulling, and to allow personnel to clearly judge the lowering depth when lowering. The counterweight block 2 is used to drive the multi-point sampling storage assembly to move down into the groundwater when lowering. The multi-point sampling storage assembly is used to perform fixed-depth sampling of groundwater at multiple depths one by one according to the requirements of multi-point fixed-depth sampling. The conical rubber sleeve 15 is used to squeeze and lock the outer side of the counterweight block 2 when it is lifted after use to prevent it from shaking, so as to ensure the anti-shaking and stable effect of the internal structure of the storage box 1 when it is carried.

[0024] Specifically, the double-position pulling and winding measuring assembly includes a rotating shaft 10 rotatably mounted on the left inner wall of the circular seat 9, wherein a second bearing is fixedly connected to the left inner wall of the circular seat 9, and the inner ring of the second bearing is fixedly sleeved on the outer side of the rotating shaft 10, which has the effect of rotatably mounting the rotating shaft 10.

In addition, the two measuring ropes 12 are pulled and released simultaneously to form a two-point pulling effect.

[0025] Furthermore, the multi-point sampling and storage assembly includes a circular sampling seat 3 fixedly mounted on the top of the counterweight 2, a plurality of water sample storage tanks 4 are provided on the top of the circular sampling seat 3 in an annular shape and at equal intervals, a sealing plate 5 is fixedly connected to the top of the sealing plate 5, a plurality of one-way exhaust valves are fixedly mounted on the top of the sealing plate 5 and are respectively connected to the interior of the corresponding water sample storage tanks 4, the top of the one-way exhaust valve is an outlet, the bottom ends of the two measuring ropes 12 are fixedly connected to the top of the sealing plate 5, and a plurality of protective shells 6 and a plurality of solenoid valves 7 are fixedly connected to the outer bottom of the circular sampling seat 3 in an annular shape and at equal intervals, and the solenoid valves 7 are located at the corresponding In the protective shell 6, multiple solenoid valves 7 are arranged in a one-to-one correspondence with multiple water sample storage tanks 4. One end of the solenoid valve 7 extends into the corresponding water sample storage tank 4, and the other end of the solenoid valve 7 extends to the outside of the corresponding protective shell 6 and is fixedly connected with a filter screen. The outer side of the protective shell 6 is provided with a through hole that is bonded and fixed to the outer side of the other end of the corresponding solenoid valve 7. The front side of the solenoid valve 7 is fixed and electrically connected to a wireless remote control switch 8. Multiple wireless remote control switches 8 are matched with the same external remote control. Multiple solenoid valves 7 are controlled by the external remote control separately through multiple wireless remote control switches 8, which is used to facilitate personnel to pass The multiple solenoid valves 7 are remotely opened and closed one by one through an external remote controller. A groove is provided on the top of the counterweight 2, and a first battery 201 is fixedly installed on the inner wall of the bottom of the groove. The multiple solenoid valves 7 are electrically connected to the first battery 201 through a wire, which plays the role of powering the multiple solenoid valves 7; the circular sampling seat 3, the water sample storage tank 4, the protective shell 6 and the solenoid valve 7 are arranged in coordination, and the circular sampling seat 3 is driven to move down into the groundwater by the downward moving counterweight 2. When the measuring rope 12 is lowered to the first depth required for sampling by observing the scale line, the personnel opens one of the solenoid valves 7 Because it is in the water body, the water pressure causes the water to automatically enter the corresponding water sample storage tank 4 through the opened solenoid valve 7. After waiting for ten seconds for the water to fully enter, the personnel closes the opened solenoid valve 7 and turns on the brake motor 13 again to lower it to the next depth required for sampling, and then opens the next solenoid valve 7 to carry out sampling in the next water sample storage tank 4. And so on, it can achieve the effect of sampling the groundwater at multiple depths one by one according to the requirements of multi-point fixed-depth sampling. There is no need to obtain a sample, lift it up, discharge the water sample, and then lower it again for sampling, thereby improving the convenience of multi-point sampling.

[0026] The method of use of this embodiment is as follows: when taking multi-point fixed-depth sampling of groundwater, the personnel first starts the brake motor 13 in the positive direction to drive the rotating shaft 10 to rotate, and the rotating shaft 10 drives the two winding wheels 11 to rotate synchronously, and the two measuring ropes 12 are released synchronously. As they are released, the counterweight block 2, the circular sampling seat 3 and the sealing plate 5 move downward under the action of their own gravity, and drive the bottom ends of the two measuring ropes 12 to move downward, and use the downward-moving counterweight block 2 to drive the circular sampling seat 3 to move down and sink into the groundwater. The personnel can clearly judge the lowering depth by observing the scale line of the measuring rope 12. When it is lowered to the first depth required for sampling, the personnel turn off the brake motor 13, and then use the external remote control to control the corresponding The wireless remote control switch 8 controls one of the solenoid valves 7 to open. Since the water pressure in the water body is much greater than the pressure in the water sample storage tank 4, the water automatically enters the corresponding water sample storage tank 4 through the opened solenoid valve 7. After waiting for ten seconds for the water to fully enter, the personnel closes the opened solenoid valve 7 and opens the brake motor 13 in the positive direction again to lower it to the next depth where sampling is required. Then, the next solenoid valve 7 is opened to inject the sample into the next water sample storage tank 4. And so on, the effect of sampling the groundwater at multiple depths one by one according to the requirements of multi-point fixed-depth sampling is achieved. There is no need to lift and discharge the water sample after obtaining a sample and then lower it again for sampling, thereby improving the convenience and efficiency of multi-point sampling.

[0027] After the sampling is completed, the personnel starts the brake motor 13 in the reverse direction, so that it drives the two winding wheels 11 to rotate through the rotating shaft 10, and the two measuring ropes 12 are wound synchronously. At this time, the two measuring ropes 12 pull the circular sampling seat 3 and the counterweight block 2 up through the sealing plate 5. After moving out, the personnel can control the corresponding solenoid valve 7 to open and let the water sample flow out. The water samples flowing out of the corresponding solenoid valve 7 can be collected by using multiple bottles for placing water samples outside. After the water samples are taken out, the personnel can start the brake motor 13 in the reverse direction again to make the circular sampling seat 3 continue to When the measuring rope 12 is moved upward, the circular sampling seat 3 is gradually moved upward and stored in the storage box 1. The circular sampling seat 3 drives the outer side of the truncated cone structure on the top of the counterweight 2 to be squeezed tightly with the inner side of the conical rubber sleeve. Under the squeezing friction between the two, the sampling structures such as the circular sampling seat 3 that are stored and protected are stabilized and prevented from shaking, and the sampling structure is prevented from shaking, colliding and being damaged when carried due to the flexibility of the measuring rope 12. The anti-sway and stable effect of the internal structure of the storage box 1 when carried is ensured, and it is convenient for personnel to directly carry it as a whole through the U-shaped handle 14.

[0028] Finally, it should be noted that the above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art will be able to modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein with equivalents.
