[0018] The exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although the exemplary embodiments of the present invention are shown in the accompanying drawings, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments described herein. On the contrary, these embodiments are provided to enable a more thorough understanding of the present invention and to fully convey the scope of the present invention to those skilled in the art.

[0019] Refer to the attached Figure 1 As shown, the experimental device for simulating the interaction between groundwater and surface water in this embodiment includes a transparent box 1 and a first permeable baffle 2 and a second permeable baffle 3 arranged inside the transparent box 1. The first permeable baffle 2 and the second permeable baffle 3 are arranged in parallel, and the inner cavity of the transparent box 1 is divided into a first space 10, a second space 20 and a third space 30 in sequence. A horizontal interactive conduit 4 is provided on the outer side of the upper part of the transparent box 1, one end of the horizontal interactive conduit 4 is communicated with the inside of the first space 10, and the other end thereof is communicated with the inside of the third space 30, and a peristaltic pump 5 is provided on the horizontal interactive conduit 4.

[0020] A submerged flow exchange conduit 6 is provided on the outer side of the bottom of the transparent box 1, one end of the submerged flow exchange conduit 6 is inserted from the bottom of the first space 10 and communicated with the interior of the first space 10, and the other end of the submerged flow exchange conduit 6 extends upward from the outer side of the bottom of the transparent box 1, and then inserted from the side wall of the third space 30, and communicated with the interior of the third space 30.

[0021] In this embodiment, the transparent box 1 is used to fill sand, gravel, silt and the like with different particle sizes, so as to accurately simulate the occurrence and migration environment of groundwater, so that the simulation of the experimental device is closer to the actual field environment. Of course, the selected sand is preferably colorless or white, otherwise it will affect the flow direction of water inside the box, which is not conducive to observation.

[0022] The peristaltic pump 5 used in this embodiment can be stably installed on the side wall of the box, providing sufficient power for the water inside the box to ensure the normal progress of the experiment. This embodiment uses a peristaltic pump with a power of 100ml / min, which can normally maintain the flow of the interaction between groundwater and surface water.

[0023] The transparent box 1, the horizontal exchange conduit 4 and the undercurrent exchange conduit 6 described in this embodiment are all made of acrylic material, which facilitates the observation of the water flow direction inside the box.

[0024] In order to prevent sand and gravel inside the box from entering the peristaltic pump 5, filter screens are provided at both ends of the horizontal interactive conduit 4.

[0025] In this embodiment, both ends of the subsurface exchange conduit 6 are also provided with filter screens to prevent sand and gravel from entering the conduit.

[0026] When the experimental device for simulating the interaction between groundwater and surface water in this embodiment is used, the first space 10, the second space 20 and the third space 30 of the transparent box 1 are filled with gravel and sand to simulate the underground environment; then, the transparent box 1 is filled with water to completely cover and submerge the gravel in the box, and the peristaltic pump 5 is started. The water in the box is driven to flow by the power of the peristaltic pump 5, such as driving the water to circulate in the first space 10, the second space 20, the third space 30, the horizontal interaction conduit 4, and the first space 10 to simulate "horizontal interaction". After the water flow is stable, an appropriate amount of dye is added to the water in the first space 10. At this time, the flow direction of the water dyed by the dye is observed, and it is found that the water not only flows horizontally along the first space 10, the second space 20, and the third space 30, but also flows into the undercurrent exchange conduit 6 at the bottom of the box 1, and flows into the upper part of the third space 30 along the undercurrent exchange conduit 6, indicating that there is a phenomenon of "undercurrent exchange" between groundwater and surface water. That is, the experimental device can simultaneously observe the interactive process of horizontal interaction and undercurrent exchange between surface water and groundwater, and can be used for teaching and research.

[0027] A more preferred embodiment is as shown in the attached Figure 2 As shown, the experimental device for simulating the interaction between groundwater and surface water in this embodiment also includes a plurality of permeable panels 7 for being arranged inside the second space 20, as shown in the figure, two permeable panels are shown. The plurality of permeable panels 7 are arranged parallel to the first permeable partition 2. The function of the permeable panels 7 is to provide different resistances for the interaction of groundwater in the experiment, so that the flow rate of the water body changes, which is conducive to more detailed research and observation of the interactive changes of the water body under different flow conditions, and meets the needs of system research, and is flexible and practical.

[0028] Of course, the horizontal interaction conduit 4 and the subsurface exchange conduit 6 in the experimental device for simulating the interaction between groundwater and surface water in this embodiment are both detachably connected to the transparent box 1, which is conducive to the installation and modification of the box and provides convenient conditions for different uses of the box.

[0029] The utility model discloses an experimental device for simulating the interaction between groundwater and surface water, which can, under the action of a peristaltic pump, truly simulate the interactive process of horizontal interaction and undercurrent exchange between surface water and groundwater, and can achieve an intuitive display effect, thereby providing physical equipment for the popular science work on the mutual interaction between groundwater and surface water, being beneficial to teaching and research and development, and meeting the needs of teaching aids and research use.

[0030] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any form. Those skilled in the art may make some simple modifications, equivalent changes or modifications using the technical contents disclosed above, which are all within the protection scope of the present invention.
