[0023] Embodiment 1

[0024] like Figure 1As shown:

[0025] A multi-layer groundwater sampling device for a hydrogeological hole comprises a suspension rope 1.

[0026] In this embodiment: the existing {public announcement number}: CN210375800U discloses a multi-layer groundwater sampling device for a hydrogeological hole. This patent discloses a rope, and the suspension rope 1 in the present application document adopts the same technical means in this prior art. This technical means will not be described one by one here. For details about the improvement of this prior art, please refer to the disclosed technology below; to solve the technical problems existing in this prior art, as disclosed in the background technology above, "when the device is sampling in a geological hole, its body may touch the inner wall of the hole, thereby causing debris to fall into the interior of the container, thereby affecting the water quality, and when the device is in contact with the water surface, it may float on the water surface, making it difficult for water to enter the container, thereby increasing the difficulty of sampling." In terms of combined use, this problem is obviously a real problem that exists and is relatively difficult to solve. In view of this, in order to solve the above problems, a sealing plate 2 and a slide chute 3 are added on this basis.

[0027] More specifically:

[0028] like Figure 1 - Figure 5 As shown:

[0029] In combination with the above content: it also includes a blocking piece 2, a slide groove 3, a slider 4, a spring 5, a positioning block 6, a sampling bucket 7, a water permeable hole 8, a balancing frame 9 and a sealing cover 10 arranged on one side of the lifting rope 1. One end of the lifting rope 1 passes through the sealing cover 10 and is fixedly connected to the balancing frame 9 fixedly installed on the surface of the sampling bucket 7 and one end of the blocking piece 2. The slide groove 3 opened on the surface of the blocking piece 2 and the slider 4 fixedly installed on the inner surface of the lifting rope 1 are slidably connected, and one end surface of the slider 4 is fixedly connected to one end of the spring 5, and the other end of the spring 5 is fixedly connected to the inner surface of the lifting rope 1. The other side of the slider 4 is also provided with a spring 5 that forms an integrated structure with the sampling bucket 7. The surface of the sampling bucket 7 is also provided with a water permeable hole 8, and the surface of the sampling bucket 7 and the sealing cover 10 are fitted and connected.

[0030] In this embodiment: when it is necessary to put the sampling bucket 7 into the geological hole to collect water samples, the sealing cover 10 and the sampling bucket 7 can be put into the geological hole through the lifting rope 1. At this time, the sampling bucket 7 and the sealing cover 10 will gradually descend. At this time, the sampling bucket 7 will inevitably touch the inner wall of the geological hole, and the sealing cover 10 can prevent the debris on the inner wall from falling into the interior of the sampling bucket 7. At the same time, the lifting rope 1 has a certain pulling force on the sealing piece 2, but the pulling force is small at this time, the sealing piece 2 does not contact the water permeable hole 8, and the length of the spring 5 on one side of the sealing piece 2 is also short. When the sampling bucket 7 contacts the water surface, moisture will enter the sampling bucket 7 through the water permeable hole 8 opened on the surface of the sampling bucket 7. Inside, the sampling barrel 7 is subjected to a certain buoyancy, and the tension between the sealing piece 2 and the lifting rope 1 also begins to decrease. The spring 5 is also completely contracted at this time. As the sampling barrel 7 and the sealing cover 10 gradually descend, the water will gradually fill the inside of the sampling barrel 7 through the water permeable hole 8. When the water surface completely submerges the top surface of the sampling barrel 7 and contacts the sealing cover 10, the sealing cover 10 floats on the water surface and separates from the sampling barrel 7. At this time, the water sample collection work is completed inside the sampling barrel 7. At this time, the lifting rope 1 can be pulled. Under the stability of the balance frame 9, the sampling barrel 7 will be in a vertical state. Move in the direction of the sealing cover 10 from the bottom of the water to the surface of the water. When the sampling barrel 7 and the sealing cover 1 0, the sealing cover 10 will seal the top of the sampling barrel 7 again, and with the continuous pulling of the hanging rope 1, the sampling barrel 7 will gradually float to the surface from the bottom of the water. At this time, the gravity carried by the hanging rope 1 will become larger. Under the influence of the gravity of the sampling barrel 7 and the water inside it, the hanging rope 1 will pull the sealing piece 2 and drive the sealing piece 2 and the sliding groove 3 and the slider 4 opened on its surface to slide in the direction of the positioning block 6. At this time, the other side of the sealing piece 2 will stretch the spring 5 to make it reach the extreme value of the stretching. When the sealing piece 2 and the positioning block 6 are in contact, the sealing piece 2 will seal the water permeable hole 8 at the bottom, and under the joint action of the sealing cover 10, the sampling barrel The interior of 7 is in a sealed state. At this time, when the sampling barrel 7 is lifted out of the geological hole, the sealing cover 10 on the top of the sampling barrel 7 can still block the debris falling from the hole or the inner wall for the sampling barrel 7, ensuring that the water quality inside is not affected. When the sampling barrel 7 is taken out of the geological hole, the water permeable hole 8 opened at the bottom of the sampling barrel 7 can be placed at the bottle mouth for storing water samples. When the sampling barrel 7 is connected to the bottle mouth, the force between the hanging rope 1 and the blocking piece 2 disappears, and the blocking piece 2 will be separated from the water permeable hole 8 under the contraction of the spring 5. At this time, the water taken in the sampling barrel 7 will flow into the sampling bottle through the water permeable hole 8, and the sampling of groundwater is completed.

[0031] It should be noted that the density of the sealing cover 10 is lower than the density of water, and the density of the sampling barrel 7 is higher than the density of water.

[0032] Going further:

[0033] In an optional embodiment, the blocking piece 2 and the slider 4 are arranged at equal angles inside the suspension rope 1, and the angle between each blocking piece 2 is 90 degrees.

[0034] In this embodiment: the blocking piece 2 and the slider 4 set at equal angles can provide a stable fulcrum for the blocking piece 2 and the sampling bucket 7 when the suspension rope 1 and the blocking piece 2 are connected, and the connection between the blocking piece 2 and the slider 4 can also enable a stable connection and separation between the blocking piece 2 and the water permeable hole 8.

[0035] Going further:

[0036] In an optional embodiment, the slide groove 3 is in the shape of an elliptical groove.

[0037] In this embodiment: the grooves opened on the surface of the slide groove 3 can enable the sealing piece 2 to form a stable sliding operation with the slider 4, and at the same time provide a precise moving direction for the sealing piece 2, thereby ensuring that the sealing piece 2 can seal the water permeable hole 8 to prevent water from flowing out of the sampling bucket 7.

[0038] Going further:

[0039] In an optional embodiment, the water-permeable holes 8 are opened at equal angles on the inner surface of the sampling barrel 7 .

[0040] In this embodiment: the water-permeable holes 8 opened at equal angles can allow moisture to enter the interior of the sampling barrel 7 through the water-permeable holes 8, and the water-permeable holes 8 located on the same straight line as the sealing piece 2 can block the water-permeable holes 8 when the sealing piece 2 is pulled by the suspension rope 1, thereby enabling the sampling barrel 7 to smoothly take out the water sample.

[0041] Going further:

[0042] In an optional embodiment, a circular through hole is opened on the surface of the balance frame 9, and the shape of the balance frame 9 is a "cross" shape.

[0043] In this embodiment, the "cross"-shaped balance frame 9 with a through hole can provide a stable fulcrum for the suspension rope 1, and the hole opened on the surface of the balance frame 9 is located at the midpoint of the cylinder where the sampling bucket 7 is located, so that the sampling bucket 7 can be more balanced when rising or falling.

[0044] Going further:

[0045] In an optional embodiment, the sealing cover 10 is in the shape of an umbrella-shaped structure with a circular through hole in the center.

[0046] In the present embodiment: the umbrella-shaped structure of the sealing cover 10 can be used to seal the top of the sampling barrel 7, so that the top surface of the sampling barrel 7 can be sealed when it rises or falls, thereby effectively preventing impurities from entering the interior and affecting the water quality. The through holes opened on the surface of the sealing cover 10 can accurately return to the position of the sealing cover 10 when the sampling barrel 7 rises from the bottom of the water and reconnect with the sealing cover 10, further ensuring the sealing of the interior of the sampling barrel 7.

[0047] The working principle and use process of the utility model are as follows: when it is necessary to put the sampling bucket 7 into the geological hole to collect water samples, the sealing cover 10 and the sampling bucket 7 can be put into the geological hole through the hanging rope 1. At this time, the sampling bucket 7 and the sealing cover 10 will gradually descend. At this time, the sampling bucket 7 will inevitably touch the inner wall of the geological hole, and the sealing cover 10 can prevent the debris on the inner wall from falling into the interior of the sampling bucket 7. At the same time, the hanging rope 1 has a certain pulling force on the plugging piece 2, but the pulling force is small at this time, the plugging piece 2 does not contact the water permeable hole 8, and the extended length of the spring 5 on one side of the plugging piece 2 is also short. When the sampling bucket 7 contacts the water surface, water will enter through the water permeable hole 8 opened on the surface of the sampling bucket 7. When the water level is lowered to the bottom of the sampling barrel 7, the sampling barrel 7 is subjected to a certain buoyancy, and the tension between the sealing piece 2 and the lifting rope 1 also begins to decrease. The spring 5 is also completely contracted at this time. As the sampling barrel 7 and the sealing cover 10 gradually descend, the water will gradually fill the inside of the sampling barrel 7 through the water permeable holes 8. When the water surface completely covers the top surface of the sampling barrel 7 and contacts the sealing cover 10, the sealing cover 10 floats on the water surface and separates from the sampling barrel 7. At this time, the water sample collection work is completed inside the sampling barrel 7. At this time, the lifting rope 1 can be pulled up. Under the stability of the balance frame 9, the sampling barrel 7 will move vertically from the bottom of the water to the direction where the sealing cover 10 is located on the water surface. When the sampling barrel 7 When in contact with the sealing cover 10, the sealing cover 10 will seal the top of the sampling barrel 7 again, and with the continuous pulling of the hanging rope 1, the sampling barrel 7 will gradually float to the surface from the bottom of the water. At this time, the gravity carried by the hanging rope 1 will become larger. Under the influence of the gravity of the sampling barrel 7 and the water inside it, the hanging rope 1 will pull the sealing piece 2 and drive the sealing piece 2 and the slide groove 3 and the slider 4 opened on its surface to slide in the direction of the positioning block 6. At this time, the other side of the sealing piece 2 will stretch the spring 5 to make it reach the extreme value of the stretching. When the sealing piece 2 and the positioning block 6 come into contact, the sealing piece 2 will seal the water permeable hole 8 at the bottom, and under the joint action of the sealing cover 10, The interior of the sampling barrel 7 is in a sealed state. At this time, when the sampling barrel 7 is lifted out of the geological hole, the sealing cover 10 on the top of the sampling barrel 7 can still block the debris falling from the hole or the inner wall for the sampling barrel 7, ensuring that the water quality inside is not affected. When the sampling barrel 7 is taken out of the geological hole, the water permeable hole 8 opened at the bottom of the sampling barrel 7 can be placed at the bottle mouth for storing water samples. When the sampling barrel 7 is connected to the bottle mouth, the force between the hanging rope 1 and the blocking piece 2 disappears, and the blocking piece 2 will be separated from the water permeable hole 8 under the contraction of the spring 5. At this time, the water taken in the sampling barrel 7 will flow into the sampling bottle through the water permeable hole 8, and the sampling of groundwater is completed.
