[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] Embodiment 1

[0023] like Figure 1 As shown:

[0024] A hydrogeological water level observation device comprises a measuring cylinder 1.

[0025] In this embodiment: the existing {public announcement number}: CN219223861U discloses a water level observation device; in order to solve the technical problems existing in this prior art, as disclosed in the background technology above, "when the device is observing the water level, it can only be read when it is placed in the water body, and when it is taken out of the water, the marks of water stains on its surface will evaporate quickly, which will cause inconvenience in observation and recording work." In terms of combined use, this problem is obviously a real problem that is difficult to solve. In view of this, in order to solve the above problems, a pull rod 2 and a handle 3 are added on this basis.

[0026] More specifically:

[0027] like Figure 1 - Figure 4 As shown:

[0028] In combination with the above content: it also includes a pull rod 2, a handle 3, a buoy 4, a counterweight 5, a water permeable hole 6, a water level bin 7 and a drainage hole 8 arranged on one side of the measuring cylinder 1, the measuring cylinder 1 and the surface of the pull rod 2 are slidingly connected, and one end of the pull rod 2 is fixedly connected to the handle 3, and the other end of the pull rod 2 is fixedly connected to the inner surface of the measuring cylinder 1 and the surface of one side of the counterweight 5, and at the same time, the pull rod 2 is also slidingly connected to the buoy 4 that is fitted with the counterweight 5, a water permeable hole 6 is opened on the surface of the counterweight 5, and the counterweight 5 is also slidingly connected to the water level bin 7 opened inside the measuring cylinder 1, and a drainage hole 8 is also opened on the side of the measuring cylinder 1 away from the handle 3.

[0029] In this embodiment: when it is necessary to observe the water level at a certain place, the measuring cylinder 1 can be held and gradually sunk into the water. At this time, the pressure outside the measuring cylinder 1 gradually increases and is applied to the surface of the counterweight 5 through the drain hole 8. At this time, the counterweight 5 is located at the bottom of the measuring cylinder 1 and the water level bin 7 and is statically filled. When the measuring cylinder 1 reaches the bottom of the water level, the water pressure outside the measuring cylinder 1 is at its maximum. At this time, the handle 3 and the pull rod 2 can be pulled upward from the top of the measuring cylinder 1. At this time, the pull rod 2 will drive the counterweight 5 and the buoy 4 to rise. When the lowest point of the counterweight 5 is higher than the lowest point of the drain hole 8, the external water flow will flow through the drain hole 8 and the water-permeable holes 6 opened on the surface of the counterweight 5 to the top of the counterweight 5 and lift the buoy 4. When the water pressure inside the measuring cylinder 1 is consistent with the water pressure outside the measuring cylinder 1, the bottom surface of the buoy 4 is at the same height as the horizontal plane outside the measuring cylinder 1. At this time, The counterweight 5 is lowered. During this process, the change in water flow caused by the movement of the counterweight 5 in height will cause the water flow at the bottom of the counterweight 5 to flow to the top of the counterweight 5 through the water-permeable hole 6, without affecting the water level. When the counterweight 5 reaches the bottom of the measuring cylinder 1 and blocks the drainage hole 8 again, the measuring cylinder 1 can be held to remove the entire device from the water body. Due to the blocking effect of the counterweight 5, the buoy 4 will always remain in its current position under the action of buoyancy, so that the staff can read its data. After the reading is completed, the handle 3 and the pull rod 2 can be pulled again to open the drainage hole 8 through the water-permeable hole 6 and the space where the water level bin 7 is located. At this time, the water inside the measuring cylinder 1 will be discharged through the drainage hole 8, and the buoy 4 will also drop again and fit the counterweight 5. Finally, the counterweight 5 can be returned to the bottom of the measuring cylinder 1 again for the next water level observation.

[0030] It should be noted that the measuring cylinder 1 is made of glass. When the buoy 4 is raised, the height and position pointed by the buoy 4 can be clearly observed from the outside of the measuring cylinder 1, so that the data can be read conveniently.

[0031] Going further:

[0032] In an optional embodiment, a through hole matching the pull rod 2 is opened on the surface of the measuring cylinder 1 , and the through hole at the position of the pull rod 2 is communicated with the internal space of the water level bin 7 .

[0033] In the present embodiment, through the through hole opened on the top surface of the measuring cylinder 1, the handle 3 can be used to pull the pull rod 2 from the outside of the measuring cylinder 1 to generate displacement, thereby achieving the purpose of filling the measuring cylinder 1 with water. When the buoy 4 is lifted, the excess air inside the water level bin 7 can be discharged through the connection between the measuring cylinder 1 and the pull rod 2, thereby avoiding the occurrence of water level height errors.

[0034] Going further:

[0035] In an optional embodiment, the buoy 4 is in the shape of a truncated cone with a circular hole on the surface.

[0036] In this embodiment: the circular hole opened on the surface of the buoy 4 can provide favorable conditions for the sliding of the buoy 4 and the pull rod 2, and the truncated cone-shaped buoy 4 can observe the water level through the reading pointed by the edge of its bottom surface when it is in a floating state.

[0037] Going further:

[0038] In an optional embodiment, the balancing weight 5 is cylindrical in shape, and the diameter of the balancing weight 5 is the same as the diameter of the water level bin 7 .

[0039] In this embodiment: the cylindrical counterweight block 5 and the water level bin 7 can slide smoothly, thereby ensuring that the counterweight block 5 can block the drain hole 8 when it is located at the bottom of the measuring cylinder 1, so that the staff can observe the reading on the surface of the measuring cylinder 1.

[0040] Going further:

[0041] In an optional embodiment, the water-permeable holes 6 are opened at equal angles on the surface of the counterweight 5 .

[0042] In this embodiment: the water-permeable hole 6 opened on the surface of the counterweight block 5 can allow the water outside the measuring cylinder 1 to flow smoothly between the buoy 4 and the counterweight block 5 through the drainage hole 8 and the water-permeable hole 6 when the counterweight block 5 is lifted, which can provide good power for the marking work of the buoy 4.

[0043] Going further:

[0044] In an optional embodiment, the drain holes 8 are connected to the inner space of the water level bin 7 , and the drain holes 8 are opened at equal angles on the surface of the measuring cylinder 1 .

[0045] In this embodiment, the drainage holes 8 opened at equal angles can allow water to flow into the interior of the measuring cylinder 1 through the drainage holes 8 when the measuring cylinder 1 is placed under water, so that the observation of the water level height can be smoothly realized.

[0046] The working principle and use process of the utility model are as follows: when it is necessary to observe the water level at a certain place, the measuring cylinder 1 can be held and gradually sunk into the water. At this time, the pressure outside the measuring cylinder 1 gradually increases and is applied to the surface of the counterweight 5 through the drain hole 8. At this time, the counterweight 5 is located at the bottom of the measuring cylinder 1 and the water level bin 7 and is statically filled. When the measuring cylinder 1 reaches the bottom of the water level, the water pressure outside the measuring cylinder 1 is at its maximum. At this time, the handle 3 and the pull rod 2 can be pulled upward from the top of the measuring cylinder 1. At this time, the pull rod 2 will drive the counterweight 5 and the buoy 4 to rise. When the lowest point of the counterweight 5 is higher than the lowest point of the drain hole 8, the external water flow will flow through the drain hole 8 and the water-permeable holes 6 opened on the surface of the counterweight 5 to the top of the counterweight 5 and lift the buoy 4. When the water pressure inside the measuring cylinder 1 is consistent with the water pressure outside the measuring cylinder 1, the bottom surface of the buoy 4 is at the same height as the horizontal plane outside the measuring cylinder 1. At this time, the counterweight 5 can be lowered. In this process, the change of water flow caused by the movement of the moving height of the counterweight 5 will cause the water flow at the bottom of the counterweight 5 to flow to the top of the counterweight 5 through the water-permeable hole 6, without affecting the water level height. When the counterweight 5 reaches the bottom of the measuring cylinder 1 and blocks the drainage hole 8 again, the measuring cylinder 1 can be held to take the entire device out of the water body. Due to the blocking effect of the counterweight 5, the buoy 4 will always remain in its current position under the action of buoyancy, so that the staff can read its data. After the reading is completed, the handle 3 and the pull rod 2 can be pulled again to open the drainage hole 8 through the water-permeable hole 6 and the space where the water level bin 7 is located. At this time, the water inside the measuring cylinder 1 will be discharged through the drainage hole 8, and the buoy 4 will also drop again and fit with the counterweight 5. Finally, the counterweight 5 can be returned to the bottom of the measuring cylinder 1 again for the next water level observation.

[0047] Finally, it should be noted that the above are only preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions described in the above embodiments or replace some of the technical features therein by equivalents.
