Description
Technical Field
[0001] The utility model relates to the technical field of soil monitoring, and specifically relates to a simplified device suitable for collecting soil leachate water. Background Art
[0002] Leaching refers to the process in which certain mineral salts, heavy metals, or organic substances in the upper soil layer dissolve and transfer to the lower soil layer due to natural infiltration of rainwater or artificial irrigation. In heavy metal contaminated soil, heavy metal ions dissolve in water and migrate deep into the soil with water, and ultimately can transfer to groundwater, thereby polluting groundwater. In the treatment of soil heavy metal pollution, an important pollution treatment method is to add passivation and adsorption materials to the soil to passivate and adsorb heavy metals on the materials, preventing heavy metals from migrating with leachate water in the soil. An important manifestation of the passivation and adsorption effect is to detect the change in the heavy metal content in soil leachate water.
[0003] Currently, there is no very suitable device for collecting soil leachate water. Most of them bury collection bottles deep in the soil. When collecting filtrate, the soil needs to be dug out, the collection bottle needs to be buried in the soil at an appropriate depth, and when taking it out, it needs to be dug out again, which greatly increases the difficulty of collecting filtrate. Therefore, there is an urgent need to design a simplified device suitable for collecting soil leachate water. Content of the Utility Model
[0004] In order to solve the above deficiencies in the prior art, the purpose of the utility model is to provide a simplified device suitable for collecting soil leachate water.

The bottom end of the push rod penetrates through the grid frame and is fixed with a second filter screen. The second filter screen is slidably matched inside the collection box. A fastener for fixing the push rod is provided on the cylinder.
[0007] Further, a sealing strip is fixed on the peripheral side surface of the grille frame, and a plurality of hinge seats are fixed on the lower surface of the grille frame. The top end of the rubber grille plate is rotatably connected to the hinge seats.
[0008] Further, an inner lining plate is arranged inside the rubber grille plate. Two hinge plates are fixed at the top end of the inner lining plate, and the two hinge plates are respectively rotatably connected to the two end parts of the hinge seat.
[0009] Further, limiting plates are fixed on both end faces of the hinge seat, and the rubber grille plate is made of rubber material.
[0010] Further, a concave platform is formed on the inner side wall of the collection box, and a plurality of magnets for adsorbing the first filter screen are fixed on the concave platform.

[0013] Compared with the prior art, the beneficial effects of the present utility model are as follows:
[0014] 1. The simplified device applicable to the collection of soil leaching water in the example of the present utility model drives the second filter screen to move upward by pulling up the push rod, and uses the second filter screen to squeeze the rubber grille plate, so that the rubber grille plate can rotate and be closely attached to the lower surface of the grille frame, realizing the closing of the leakage groove. The push rod and the cylinder are fixedly connected through the fastener. At this time, the grille frame is pushed downward, and under the action of pressure, the soil leaching solution collected after filtration at the bottom of the collection box can be pushed into the collection bottle through the drain pipe.

[0033] Embodiment 1:
[0034] Reference Figures 1-7A simplified device suitable for collecting soil leachate water shown in the figure includes a collection box 1 and a collection bottle 3. A drain pipe 2 is fixedly connected to the bottom of the collection box 1. The top end of the drain pipe 2 is connected to the collection bottle 3. A check valve is installed at the bottom of the drain pipe 2. A first filter screen 10 is detachably fixed inside the collection box 1. A grille frame 11 is slidably fitted at a position below the first filter screen 10 inside the collection box 1. A number of leakage grooves 14 are formed on the grille frame 11. And a number of gelatinous grille plates 13 for closing the leakage grooves 14 are rotatably connected to the lower surface of the grille frame 11. A cylinder 4 is fixed on the upper surface of the grille frame 11. A push rod 9 is slidably fitted inside the cylinder 4. And the top of the cylinder 4 slidably penetrates through the first filter screen 10. The bottom end of the push rod 9 penetrates through the grille frame 11 and is fixed with a second filter screen 12. The second filter screen 12 is slidably fitted inside the collection box 1. A fastener for fixing the push rod 9 is provided on the cylinder 4.
[0035] In the utility model, the top end of the drain pipe 2 is exposed on the soil surface, which is convenient for the collection bottle 3 to receive water. The setting of the check valve enables the soil leachate solution in the drain pipe 2 not to flow back into the interior of the collection box 1. It can make the soil leachate solution in the collection box 1 be completely discharged into the collection bottle 3 through the drain pipe 2 under the repeated pressing of the grille frame 11, avoiding the mixing of the residual soil leachate solution in the drain pipe 2 with the subsequently collected soil leachate solution and affecting the detection result. The water in the soil passes through the leakage grooves 14 after being filtered by the first filter screen 10 and is filtered again by the second filter screen 12, and finally is collected at the bottom of the collection box 1. By pulling up the push rod 9 to drive the second filter screen 12 to move upward, the gelatinous grille plates 13 are squeezed by the second filter screen 12, so that the gelatinous grille plates 13 rotate upward and closely fit the lower surface of the grille frame 11, realizing the closing of the leakage grooves 14. The push rod 9 is fixedly connected to the cylinder 4 through the fastener. At this time, when the grille frame 11 is pushed downward, under the push of the pressure, the filtered soil leachate solution collected at the bottom of the collection box 1 can be pushed into the interior of the collection bottle 3 through the drain pipe 2.
[0036] In order to improve the closing effect of the rubberized grille plate 13 on the leakage trough 14, in this embodiment, a sealing strip 16 is fixed on the peripheral side surface of the grille frame 11, and a plurality of hinge seats 15 are fixed on the lower surface of the grille frame 11. The top end of the rubberized grille plate 13 is rotatably connected to the hinge seats 15. An inner lining plate 17 is provided inside the rubberized grille plate 13. Two hinge plates 18 are fixed at the top end of the inner lining plate 17, and the two hinge plates 18 are respectively rotatably connected to the two end portions of the hinge seats 15. Limiting plates 19 are fixed on the two end surfaces of the hinge seats 15. The rubberized grille plate 13 is made of rubber material. The setting of the inner lining plate 17 improves the structural strength of the rubberized grille plate 13, so that the rubberized grille plate 13 is not easily deformed under pressure. The setting of the limiting plates 19 plays a role in limiting, restricting the amplitude of the downward swing of the rubberized grille plate 13 under its own gravity, and preventing the rubberized grille plate 13 from being perpendicular to the second filter screen 12, thereby affecting the extrusion and closing of the second filter screen 12 on the rubberized grille plate 13. The rubberized grille plate 13 made of rubber material can make the rubberized grille plate 13 closely fit the surface of the grille frame 11 by using the elastic deformation of the rubber, improving the sealing effect on the leakage trough 14. The setting of the sealing strip 16 makes the peripheral side surface of the grille frame 11 closely fit the inner side wall of the collection box 1, ensuring that after the leakage trough 14 is closed, a squeezing force can be formed on the soil leaching solution inside the collection box 1 during the downward movement of the grille frame 11.
[0037] Embodiment Two:
[0038] The features that are the same as those in Embodiment One will not be described in detail. The features that are different from those in Embodiment One in this embodiment are as follows: As Figure 2 shown, a concave platform 20 is formed on the inner side wall of the collection box 1, and a plurality of magnets 21 for adsorbing the first filter screen 10 are fixed on the concave platform 20.
[0039] The first filter screen 10 is adsorbed and fixed by the magnets 21, which facilitates the quick disassembly and installation of the first filter screen 10. At the same time, the setting of the concave platform 20 facilitates the extraction of the grille frame 11 and the second filter screen 12 from the inside of the collection box 1, facilitating the later maintenance of the first filter screen 10, the grille frame 11, and the second filter screen 12.
[0040] Embodiment Three:
[0041] The features that are the same as those in Embodiment Two will not be described in detail. The features that are different from those in Embodiment Two in this embodiment are as follows: As Figure 2 、 3 shown, in this embodiment, the fastener includes an adjusting cylinder 6 and a bolt column 7. The bolt column 7 is fixed at the top end of the push rod 9, and the bottom of the bolt column 7 is slidably fitted inside the cylinder 4. The adjusting cylinder 6 is rotatably connected to the top end of the cylinder 4. The bolt column 7 passes through the adjusting cylinder 6 and is threadedly connected to the adjusting cylinder 6. A end plate 8 is fixed at the top end of the bolt column 7, and a handle 5 is installed on the peripheral side surface of the top of the cylinder 4.
[0042] By utilizing the threaded fit between the bolt column 7 and the adjusting cylinder 6, the bolt column 7 can be driven to rise or fall vertically, enabling easy control of the sliding of the push rod 9 in the vertical direction. Moreover, through the mechanical self-locking between the threads, the push rod 9 can be fixedly connected to the cylinder 4. The setting of the end plate 8 can prevent the bolt column 7 from sliding into the interior of the cylinder 4, playing a role in restricting the downward displacement range of the cylinder 4. The setting of the handle 5 facilitates the user to press down the cylinder 4.
[0043] Operation process: First, select an appropriate soil depth and dig a soil pit of appropriate size. Bury the collection box 1 in the dug soil pit, fill the soil to the natural height to make it flush with the surrounding soil, leaving only the drain pipe 2 and the collection bottle 3 exposed. It is possible to simulate rainfall watering or wait for natural rainfall. After a period of time, the soil leachate will accumulate at the bottom of the collection box 1. At this time, close the leakage trough 14 and press down the grille frame 11, then the soil leachate inside the collection box 1 can be pressed into the collection bottle 3.
