[0019] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0020] Referring to Figures 1 to 5 , in the embodiment of the present invention, a water level monitoring device for hydrogeological tests includes a sinking prevention plate 1. A fixed cylinder 4 is fixedly connected to the sinking prevention plate 1. A fixed rod 8 is slidably connected in the fixed cylinder 4. One end of the fixed rod 8 passes through the fixed cylinder 4 and is slidably connected to a floating tube 5. A plurality of groups of scales 6 are arranged on the outer wall of the floating tube 5. The end with a lower value of the scale 6 is arranged on the side of the scale 6 away from the sinking prevention plate 1, while the end with a larger value of the scale 6 is arranged on the side of the scale 6 close to the sinking prevention plate 1. A hollow groove 7 is arranged in the scale 6. A light-shielding cover 9 and a mounting bracket 10 are slidably connected in the floating tube 5. A light-transmitting mirror 11 is fixedly connected between the light-shielding cover 9 and the mounting bracket 10. A mounting seat 13 is fixedly connected in the light-shielding cover 9, and a light source 14 is installed in the mounting seat 13. A connecting frame 15 is fixedly connected to the outer wall of the floating tube 5, and a floating body 16 is fixedly connected to the connecting frame 15. A group of insertion rods 2 are fixedly connected to the bottom of the sinking prevention plate 1. A plurality of groups of supporting nails 3 fixedly connected to the sinking prevention plate 1 are arranged around the insertion rods 2. In the present invention, the insertion rods 2 are inserted into the bottom of the water to support and fix the device, and the stability of the device is improved through the arrangement of the supporting nails 3. According to the different water depths, the relative height of the fixed rod 8 in the fixed cylinder 4 is adjusted, so as to adjust the relative height of the floating tube 5 and the bottom of the water. At this time, the floating body 16 floats on the water surface under the push of the buoyancy generated by the water body, and the floating tube 5 is also pushed by the floating body 16 to float on the water surface. That is, when the water level changes, the relative height of the floating tube 5 and the bottom of the water will also change. At this time, relative sliding occurs between the floating tube 5 and the fixed rod 8, so that the relative distance between the light-shielding cover 9 and the floating tube 5 changes, that is, the relative distance between the light source 14 and the scale 6 changes. And the light emitted by the light source 14 is incident into the hollow groove 7 through the light-transmitting mirror 11 and then emitted along the hollow groove 7. At this time, the staff can judge the water surface height by observing the scale at the position where the light is emitted on the scale 6.

[0021] In a case of this embodiment, please refer to Figures 1 to 5 , one ends of a plurality of groups of connecting ropes 17 distributed in a circumferential manner are connected to the floating body 16, and a counterweight 18 is installed at the other ends of the connecting ropes 17. In the present invention, the counterweight 18 is installed through the arrangement of the connecting ropes 17, and the stability and anti-wave ability of the floating body 16 are increased through the arrangement of the counterweight 18, so as to reduce the influence of the waves on the measurement results.

[0022] In one case of this embodiment, please refer to Figures 1 to 5 , a sliding connection cylinder 19 is fixedly connected to the top of the floating pipe 5. A support rod 12 is slidably connected in the sliding connection cylinder 19. One end of the support rod 12 is fixedly connected to the mounting frame 10, and a photovoltaic panel 20 is installed at the other end of the support rod 12. The output end of the photovoltaic panel 20 is connected to a storage battery, and the storage battery is connected to the light source 14. First, the present utility model realizes the sliding connection between the floating pipe 5 and the support rod 12 through the setting of the sliding connection cylinder 19. At the same time, the light energy dissipated by the natural light source 14 is converted into electrical energy through the setting of the photovoltaic panel 20 and input into the storage battery. When the external light source 14 weakens and disappears, the storage battery releases energy to provide electrical energy for the light source 14.

[0023] In one case of this embodiment, please refer to Figures 1 to 5 , a threaded cylinder 21 is provided on the outer wall of the fixed cylinder 4. A fastening bolt 22 is threadedly connected in the threaded cylinder 21, and the fastening bolt 22 cooperates with the fixed rod 8. The threaded connection between the threaded cylinder 21 and the fastening bolt 22 of the present utility model installs and fixes the fastening bolt 22 into the fixed cylinder 4. When the present utility model needs to relatively fix the fixed rod 8 and the fixed cylinder 4, the staff can tighten the fastening bolt 22, and the fastening bolt 22 fastens and clamps the fixed rod 8 through the cooperation with the fixed rod 8, so that the fixed cylinder 4 and the fixed rod 8 are relatively tightly clamped. After that, when it is necessary to adjust the relative position between the fixed cylinder 4 and the fixed rod 8, just loosen the fastening bolt 22.
