Description

Technical Field

[0001] The present invention relates to the technical field of soil detection and sampling equipment, and in particular to a soil seepage liquid collection device. Background Art

[0002] Soil measurement usually requires collecting soil seepage liquid for testing. There are two common ways to collect soil seepage liquid. The first is to dig a pit of a certain depth vertically on the land, then put a collection bottle into the pit, and then place a collection bucket on the collection bottle. Then, the separated soil layer is backfilled and compacted. The seepage liquid collected by the collection bucket flows into the collection bottle, and then a water pump is used to extract the seepage liquid in the collection bottle for testing. However, this method will destroy the original structure of the soil layer, resulting in the seepage liquid collection being unable to reflect the actual situation, thereby affecting the test results.

[0003] Another is in the related technology, which can refer to the Chinese utility model patent with authorization announcement number CN220508540U, which discloses an insertable soil seepage liquid collection system, including a collecting hopper, a water storage tank and a water intake pipe, the collecting hopper includes a horizontally arranged cross plate, a rectangular cavity is provided at one end of the cross plate, a filter is provided in the rectangular cavity, a drainage hole is provided at the bottom of the rectangular cavity, a water inlet and a water outlet are provided at the top of the water storage tank, the water inlet of the water storage tank is connected to the drainage hole of the collecting hopper through a guide pipe, the lower end of the water intake pipe is connected to the water outlet of the water outlet tank, the collecting hopper is directly inserted into the soil layer to collect the seepage liquid, and the rectangular cavity limits and protects the filter to prevent the soil from damaging the filter. The collected leachate is filtered and then enters the water tank through the drainage hole and the silicone tube. When a certain amount of leachate is collected, a silicone suction pipe is extended into the bottom of the water tank. The other end of the suction pipe is connected to a water pump. The water outlet of the water pump is connected to a two-way sampling bottle for collecting the leachate. This method requires a water pump, which is costly and inconvenient to carry. In addition, the amount of leachate collected in the water tank cannot be known, thereby reducing the convenience of collecting soil leachate. Summary of the invention

[0004] In order to improve the convenience of collecting soil seepage liquid, the present invention application provides a soil seepage liquid collecting device.

[0005] The soil seepage liquid collection device provided in this application adopts the following technical solution:

[0006] A soil seepage liquid collection device comprises a collection box, a liquid collecting hopper and a water guide pipe, the collection box is buried in the soil, the collection box has a collection cavity, a plurality of sampling bottles are arranged in the collection cavity, one of the sampling bottles is located at a sampling position, the liquid collecting hopper is inserted in the soil, a filter is arranged in the liquid collecting hopper, the water guide pipe connects the liquid collecting hopper and the collection box and is used to guide the seepage liquid into the sampling bottle located at the sampling position, the collection box is provided with a liquid level assembly for marking the liquid level in the sampling bottle located at the sampling position, the collection cavity is provided with a moving mechanism for driving the next sampling bottle to move to the sampling position after the sampling bottle located at the sampling position is removed, the collection box is provided with a sampling column extending upward to the ground, the sampling column has a vertical moving cavity, the moving cavity is connected to the collection cavity, the moving cavity is provided with a moving mechanism for moving the sampling bottle located at the sampling position out, and the top of the sampling column is provided with a closing cover for closing the moving cavity.

[0007] By adopting the above technical solution, the collection box is buried in the soil, and the upper part of the sampling column extends out of the ground. The leakage liquid is filtered by the filter element and then enters the sampling bottle located at the sampling position through the water pipe. At the same time, the liquid level component indicates the liquid level in the sampling bottle. When the liquid level reaches the sampling amount, the closing cover is opened, and the moving mechanism is started to move the sampling bottle located at the sampling position into the moving cavity and the sampling bottle is taken out by the moving mechanism. At this time, the moving mechanism starts to drive the next sampling bottle to the sampling position, so as to realize multiple samplings by one burial. The sampling amount in the sampling bottle is displayed in time through the liquid level component. The soil layer will not be damaged during repeated sampling, and there is no need to carry large equipment such as water pumps. The sampling bottle can be directly taken back for testing after being taken out, thereby improving the convenience of collecting soil leakage liquid.

[0008] Optionally, the liquid level assembly includes a liquid level cylinder and a float rod, the liquid level cylinder is arranged on the collecting box and extends vertically upward to above the ground, the part of the liquid level cylinder located above the ground is a transparent column, and the top cover of the liquid level cylinder is provided with a shielding cover; the float rod is vertically penetrated in the liquid level cylinder, and a float is provided at the bottom end of the float rod, the lower end of the float rod extends into a sampling bottle located at the sampling position and the float floats on the surface of the leaked liquid in the sampling bottle.

[0009] By adopting the above technical scheme, the leaked liquid is collected into the sampling bottle through the water pipe. As the liquid level rises, the float rod rises under the action of the float. The collected amount of leaked liquid in the sampling bottle can be known by observing the position of the top of the float rod in the liquid level cylinder. When the sampling amount is reached, the moving mechanism is started to move the sampling bottle out. At the same time, the shielding cover is opened, and the top of the float rod is pulled so that the float does not affect the movement of the sampling bottle. After the next sampling bottle moves to the sampling position, the float rod is lowered. The float rod descends under the action of gravity and the lower end extends into the sampling bottle at the sampling position. During the collection of the leaked liquid, the shielding cover blocks the top of the liquid level cylinder to reduce the probability of external dust and impurities entering the sampling bottle through the liquid level cylinder, which not only improves the convenience of collecting the leaked liquid, but also reduces the probability of the leaked liquid being contaminated by external impurities.

[0010] Optionally, the moving mechanism includes a guide rail, a base and a limit assembly, wherein two guide rails are provided, the two guide rails are arranged in parallel in the collecting chamber and extend along the length direction of the collecting chamber, and a plurality of sampling bottles are arranged on the guide rails in sequence, the guide rail includes an inclined section and a smooth section, the inclined section extends downwardly from the other end toward the smooth section, and the sampling bottle moved to the smooth section is located at the sampling position; the base corresponds to the sampling bottle one by one, the sampling bottle is fixed in the corresponding base, and rollers that roll with the guide rails are respectively provided on both sides of the base; the limit assembly is arranged at one end of the smooth section away from the inclined section and is used to prevent the roller from sliding out of the guide rail.

[0011] By adopting the above technical solution, multiple sampling bottles are arranged on the guide rail in sequence, the sampling bottle on the smooth section is located at the sampling position, the limiting component blocks the sampling bottle at the sampling position, and prevents the roller from sliding out of the guide rail during the sampling process. When the sampling bottle at the sampling position completes sampling, the moving mechanism drives the base to move out of the guide rail. At this time, the sampling bottle on the inclined section moves to the smooth section through the roller until the next sampling bottle is located at the sampling position. At this time, the limiting component blocks the sampling bottle at the sampling position, and the operation is repeated to achieve multiple samplings, thereby improving the convenience of collecting soil seepage liquid.

[0012] Optionally, the limiting assembly includes a limiting plate and a torsion spring, wherein the limiting plate is rotatably arranged at one end of the smooth section away from the inclined section and is used to block the front end of the guide rail; one end of the torsion spring is connected to one end of the smooth section away from the inclined section and the other end is connected to the limiting plate.

[0013] By adopting the above technical solution, during normal sampling, the limit plate blocks the front end of the guide rail and the base will not slide out of the guide rail. After sampling of a single sampling bottle is completed, the moving mechanism starts to drive the base to move. Under the external force of the moving mechanism, the roller pushes the limit plate to rotate, and the torsion spring is deformed. When the roller is separated from the limit plate, the torsion spring restores the deformation, the limit plate rotates back to the initial position, and blocks the next sampling bottle, thereby achieving the limitation of the sampling bottle at the sampling position, improving the stability of the sampling bottle, and thus improving the convenience of collecting the leaked liquid.

[0014] Optionally, the removal mechanism includes a lifting rod and a connecting assembly, the lifting rod is arranged in the movable cavity and extends vertically; the connecting assembly is arranged at the bottom end of the lifting rod and is used to connect the lifting rod and the sampling bottle.

[0015] By adopting the above technical solution, after sampling of the sampling bottle located at the sampling position is completed, the connecting component connects the lifting rod and the sampling bottle, opens the closing cover, pulls the lifting rod to drive the sampling bottle to move, and the roller pushes the limit plate to rotate and move out of the guide rail. At this time, the sampling bottle moves from the collection chamber to the moving chamber, and then pulls the lifting rod upward, the lifting rod drives the base and the sampling bottle to move upward as a whole until the sampling bottle moves out of the moving chamber, thereby completing the removal of a single sampling bottle. After removal, put the lifting rod back in place, and the connecting component reconnects the lifting rod and the next sampling bottle located at the sampling position. After sampling is completed Repeat the operation to remove the sampling bottle, thereby improving the convenience of soil seepage liquid sampling; when the sampling bottles in the collection box have been sampled, a new sampling bottle can be placed in reverse through the lifting rod and the connecting assembly, and the lifting rod is pushed to drive the sampling bottle to move into the collection chamber and be located on the smooth section, and multiple bottles are placed in sequence, and the later placed sampling bottle pushes the earlier placed sampling bottle to move from the smooth section to the inclined section, so that large-scale seepage liquid sampling of the soil at the same position can be achieved without damaging the soil structure and without the need for a water pump, thereby improving the convenience of continuous sampling of seepage liquid in the same piece of soil.

[0016] Optionally, the connecting component includes a clamping piece, a first magnetic plate and a second magnetic plate, two clamping pieces are provided and are arranged on both sides of the lifting rod, and hanging ears are provided on both side walls of the base, the clamping piece corresponds to the hanging ears one by one, and when the clamping piece is inserted into the corresponding hanging ears, the lifting rod can be moved to move the sampling bottle located at the sampling position out; the first magnetic plate is detachably provided on the side wall of the lifting rod facing the base through a thread; the second magnetic plate is detachably provided on the side wall of the base facing the lifting rod through a thread, and when the sampling bottle is moved out, the first magnetic plate and the second magnetic plate are adsorbed.

[0017] By adopting the above technical solution, when the sampling bottle needs to be taken out, the first magnetic plate is threadedly connected to the bottom end of the lifting rod, and then the lifting rod is moved so that the clamping piece is inserted into the corresponding hanging ear. At this time, the first magnetic plate and the second magnetic plate are adsorbed together, and the two clamping pieces clamp the base. At this time, the lifting rod is pulled to drive the base to move, and the roller drives the limit plate to rotate. After the base moves into the moving cavity, the lifting rod is pulled upward to drive the base and the sampling bottle to move upward as a whole until the sampling bottle is moved out, and then the lifting rod is put back to the initial position, and the lifting rod is connected to the next sampling bottle located at the sampling position, so as to improve the convenience of removing the sampling bottle, thereby improving the convenience of collecting soil seepage liquid; when the sampling bottle needs to be added, the first magnetic plate is removed from the lifting rod, and then The clamping piece is inserted in the corresponding hanging ear, and the lifting rod is pushed to drive the new base and the sampling bottle to move down as a whole to the connection between the collecting chamber and the movable chamber. At this time, the base is located above the limiting plate, and the lifting rod is pushed to move the base to the sampling position, and then the lifting rod is moved down so that the roller is located in the guide rail, and then the lifting rod is pulled to make the clamping piece separate from the hanging ear. Since there is no magnetic attraction between the lifting rod and the base, the limiting plate can block the roller. Repeat the operation to place multiple sampling bottles, and the next sampling bottle to be placed pushes the sampling bottle on the smooth section to move to the inclined section. Repeat the placement of all sampling bottles, thereby realizing large-scale seepage liquid sampling of the same position of the soil, will not damage the soil structure, and no water pump is required, thereby improving the convenience of continuous sampling of seepage liquid in the same piece of soil.

[0018] Optionally, two opposite inner side walls of the movable cavity are provided with placement grooves for placing the lifting rod, and an outer side wall of the lifting rod is rotatably provided with a handle for facilitating leverage.

[0019] By adopting the above technical solution, the placement groove limits the lifting rod. When the lifting rod is located in the placement groove close to the sampling bottle, the clamping piece is just inserted into the corresponding hanging ear, thereby improving the convenience of connecting the lifting rod to the base. The convenience of pulling the lifting rod to move is improved by leveraging the handle, thereby improving the convenience of removing and placing the sampling bottle, thereby improving the convenience of collecting soil seepage liquid.

[0020] Optionally, a rotating shaft is fixedly provided on the inner wall of the top of the sampling bottle, and the rotating shaft extends radially along the sampling bottle. The float and the water conduit are respectively located on both sides of the rotating shaft. A rotating cover is rotatably provided on the rotating shaft, and the rotating cover covers the sampling bottle in an initial state.

[0021] By adopting the above technical scheme, when sampling is not performed, the rotating cover blocks the opening of the sampling bottle, thereby reducing the probability of impurities and dust entering the sampling bottle. For the sampling bottle located at the sampling position, the float rod moves downward under the action of gravity, and the float pushes the rotating cover to rotate around the rotating axis, and the float extends into the sampling bottle. At this time, due to the rotation of the rotating cover, the rotating cover located below the float rotates into the sampling bottle, and the rotating cover located below the water pipe rotates upward and opens the bottle mouth of the sampling bottle. At this time, the leakage liquid can drip into the sampling bottle through the water pipe. As the leakage liquid is collected, the float gradually rises, and the rotating cover gradually rotates. After reaching the sampling amount, the rotating cover moves back to the initial position and blocks the bottle mouth of the sampling bottle. At this time, the sampling bottle that has completed sampling is moved out by the lifting rod, and the next sampling bottle moves to the sampling position for repeated sampling, thereby improving the accuracy of soil leakage liquid sampling and reducing the probability of impurities mixing into the leakage liquid.

[0022] Optionally, a water outlet is coaxially provided at the bottom end of the water pipe, and the diameter of the water outlet is smaller than the inner diameter of the water pipe. A plug is provided in the water pipe, and the diameter of the plug is smaller than the inner diameter of the water pipe and larger than the diameter of the water outlet. A linkage component is provided between the float and the plug, and when the page in the sampling bottle at the sampling position reaches a set value, the float drives the plug from top to bottom through the linkage component to seal the water outlet.

[0023] By adopting the above technical scheme, when the float moves downward, the plugging head is driven to move upward in the water pipe through the linkage component. At this time, the leakage liquid drips into the sampling bottle through the water pipe and the water outlet. When the float gradually moves upward, the plugging head is driven from top to bottom through the linkage component. When the sampling amount is reached, the plugging head moves to the water outlet position and blocks the water outlet. At this time, the leakage liquid in the water pipe is blocked, so as to control the sampling amount in a single sampling bottle. When heavy rain or flood disasters occur, the leakage liquid suddenly increases and impacts the plugging head. The plugging head moves downward quickly and seals the water outlet. The plugging head drives the float to move upward through the linkage component, and the rotating cover rotates and blocks the bottle mouth of the sampling bottle. After heavy rain, re-sampling can be achieved by manually pushing the float rod. Only the sampling bottle currently located at the sampling position may have residual rainwater or other water sources. Switch to the next sampling bottle for re-sampling. Heavy rain and other water sources will not pollute the collected liquid in all sampling bottles, thereby improving the convenience and accuracy of soil leakage liquid collection.

[0024] Optionally, a moving rod with a diameter smaller than the inner diameter of the water outlet is provided for vertical sliding in the water outlet, the plugging head is fixed at the top of the moving rod, and the linkage assembly includes a central axis, a central connecting rod, a main connecting rod and a secondary connecting rod. The central axis is fixed in the collecting chamber and is located above the sampling position, and the central axis extends horizontally in a direction perpendicular to the moving direction of the sampling bottle; the central connecting rod is rotatably arranged on the central axis, and the end of the central connecting rod close to the float has a first hinge point, and the end of the central connecting rod close to the water outlet has a second hinge point; the two ends of the main connecting rod are respectively hinged to the float and the first hinge point; the two ends of the secondary connecting rod are respectively hinged to the second hinge point and the bottom end of the moving rod.

[0025] By adopting the above technical solution, when the float moves downward, the float pulls the main connecting rod to rotate counterclockwise, the main connecting rod pushes the central connecting rod to rotate clockwise and then counterclockwise around the central axis, the other end of the central connecting rod pulls the secondary connecting rod to push the moving rod upward, the moving rod pushes the plugging head upward, at this time the leakage liquid passes through the water pipe and the water outlet and drips into the sampling bottle, when the float moves upward, it drives the plugging head to move downward until the plugging head blocks the water outlet, and the sampling bottle completes sampling, similarly, when it rains heavily, rainwater enters the water pipe and impacts the plugging head, the plugging head moves quickly under the impact and blocks the water outlet, the movement of the plugging head drives the float to move upward, and the rotating cover rotates to the initial position, thereby realizing the linkage between the float and the plugging head, thereby improving the convenience of sampling and collecting soil leakage liquid.

[0026] In summary, the present application includes at least one of the following beneficial technical effects:

[0027] 1. The collection box is buried in the soil, and the upper part of the sampling column extends out of the ground. The leakage liquid is filtered by the filter element and then enters the sampling bottle located at the sampling position through the water pipe. At the same time, the liquid level component indicates the liquid level in the sampling bottle. When the liquid level reaches the sampling amount, the closing cover is opened, and the moving mechanism is started to move the sampling bottle located at the sampling position into the moving cavity and the sampling bottle is taken out by the moving mechanism. At this time, the moving mechanism starts to drive the next sampling bottle to the sampling position, so as to realize multiple samplings with one burial. The sampling amount in the sampling bottle is displayed in time through the liquid level component. The soil layer will not be damaged during repeated sampling, and there is no need to carry large equipment such as water pumps. The sampling bottle can be taken out and directly taken back for testing, thereby improving the convenience of collecting soil leakage liquid.

[0028] 2. The convenience of observing the collected amount in the sampling bottle is improved by setting a float rod, and the continuity and stop of sampling are realized through the linkage between the float and the plugging head, thereby improving the convenience of collecting soil seepage liquid.

[0029] 3. When it is necessary to take out the sampling bottle, the sampling bottle that has been sampled is moved out through the cooperation of the first magnetic plate, the second magnetic plate, the clamping piece and the hanging ear, and the next sampling bottle slides from the inclined section to the sampling position for sampling, thereby realizing continuous sampling and improving the convenience of removing the sampling bottle. When it is necessary to add a sampling bottle, the first magnetic plate is removed from the lifting rod, and then the clamping piece is inserted into the corresponding hanging ear, and the lifting rod is pushed to drive the new base and the sampling bottle to move down as a whole to the connection between the collection chamber and the moving chamber. At this time, the base is located above the limit plate, and the lifting rod is pushed to make the base Move to the sampling position, then move the lifting rod downward so that the roller is located in the guide rail, and then pull the lifting rod to make the clamping piece separate from the hanging ear. Since there is no magnetic attraction between the lifting rod and the base, the limit plate can block the roller. Repeat the operation to place multiple sampling bottles. The next sampling bottle to be placed pushes the sampling bottle on the smooth section to move to the inclined section. Repeat the placement of all sampling bottles to achieve large-scale seepage liquid sampling in the same position of the soil without damaging the soil structure and without the need for a water pump, thereby improving the convenience of continuous sampling of seepage liquid in the same piece of soil.

[0049] Reference Figure 7 , Figure 8 and Fig. 9The limiting component 73 is arranged at one end of the smooth section 712 away from the inclined section 711 and is used to prevent the roller 721 from sliding out of the guide rail 71. Two limiting components 73 are provided and correspond one to one with the guide rail 71. The following only takes one limiting component 73 as an example for explanation; the limiting component 73 includes a limiting plate 731 and a torsion spring 732. The limiting plate 731 is rotatably arranged at one end of the smooth section 712 away from the inclined section 711 and is used to block the front end of the guide rail 71. One end of the torsion spring 732 is connected to one end of the smooth section 712 away from the inclined section 711 and the other end is connected to the limiting plate 731. When the roller 721 abuts against the side wall of the limiting plate 731, the sampling bottle 4 on the base 72 provided with the roller 721 is just located at the sampling position.

[0050] Reference Figure 2 , Figure 7 and Fig.10 The movable chamber 131 is provided with a moving out mechanism 8 for moving the sampling bottle 4 located at the sampling position out. The moving out mechanism 8 includes a lifting rod 81 and a connecting assembly 82. The lifting rod 81 is arranged in the movable chamber 131 and extends vertically. The movable chamber 131 has two opposite inner side walls provided with placement grooves 133 for placing the lifting rod 81. A handle 811 for facilitating leverage is rotatably provided on the outer side wall at the top of the lifting rod 81. The connecting assembly 82 is arranged at the bottom end of the lifting rod 81 and is used to connect the lifting rod 81 and the sampling bottle 4. The connecting assembly 82 includes a clamping piece 821, a first magnetic attraction plate 822 and a second magnetic attraction plate 823. Two clamping pieces 821 are provided and are arranged on both sides of the lifting rod 81. Both side walls of the base 72 are provided with hanging ears 722. The clamping piece 821 corresponds to the hanging ears 722 one by one. When the clamping piece 821 is inserted into the corresponding hanging ears 722, the lifting rod 81 can be moved to move the sampling bottle 4 located at the sampling position out.

[0051] Reference Figure 2 , Figure 5 and Fig.10 The first magnetic plate 822 is provided with a first threaded column 824, and the first threaded column 824 is detachably arranged on the side wall of the lifting rod 81 facing the base 72 through a thread. The second magnetic plate 823 is provided with multiple and corresponds to the sampling bottle 4 one by one. The second magnetic plate 823 is provided with a second threaded column 825, and the second threaded column 825 is detachably arranged on the side wall of the base 72 facing the lifting rod 81 through a thread. When the sampling bottle 4 is removed, the first magnetic plate 822 and the second magnetic plate 823 are adsorbed. In order to extend the service life of the first magnetic plate 822 and the second magnetic plate 823, an anti-rust coating can be applied to the first magnetic plate 822 and the second magnetic plate 823 as needed in actual applications; when the lifting rod 81 is located in the placement groove 133 close to the sampling bottle 4, the clamping sheet 821 is inserted in the hanging ear 722, and the first magnetic plate 822 and the second magnetic plate 823 are adsorbed.

[0052] Reference Figure 2 , Figure 5 and Figure 7 Before burying the collecting box 1, take out the sampling bottles 4 that need to be used, rotate and remove the external cover, first lift the float rod 52 upwards through the lifting ring 521, and then place multiple sampling bottles 4 on the inclined section 711 in sequence through the placement port 12. The base 72 drives the sampling bottles 4 to move toward the smooth section 712 under the action of the roller 721, and the limit plate 731 blocks the front end of the guide rail 71, and the base 72 will not slide out of the guide rail 71 until all the sampling bottles 4 are placed on the guide rail 71, cover with the sealing cover 121, and then insert the liquid collecting hopper 2 at the soil sampling point, and then bury the collecting box 1 in the soil, connect the liquid collecting hopper 2 and the collecting box 1 through the water pipe 3, and then place the lifting rod 81 in the placement groove 133, cover with the closing cover 132, and then backfill the excavated soil, and insert an identification plate on the soil surface.

[0053] Reference Figure 3 , Figure 6 and Figure 7 , put down the float rod 52 and cover it with a shielding cover 512. The float rod 52 falls under its own gravity, and the float 53 pushes the rotating cover 43 to rotate around the rotating shaft 42. The float 53 extends into the sampling bottle 4. At this time, due to the rotation of the rotating cover 43, the rotating cover 43 located below the float 53 rotates into the sampling bottle 4, and the rotating cover 43 located below the water pipe 3 rotates upward and opens the bottle mouth of the sampling bottle 4. At the same time, the float 53 pulls the main connecting rod 63 to rotate counterclockwise, and the main connecting rod 63 pushes the central connecting rod 62 to rotate. The other end of the central connecting rod 62 pulls the secondary connecting rod 64 to push the moving rod 33 to move upward, and the moving rod 33 pushes the plugging head 32 to move upward. At this time, the filtered leakage liquid can drip into the sampling bottle 4 through the water pipe 3 and the water outlet 31.

[0054] Reference Figure 5 and Figure 7 As the leaked liquid is collected, the float 53 gradually rises. The amount of leaked liquid collected in the sampling bottle 4 can be determined by the change in the position of the top end of the float rod 52 in the transparent column 511. The float 53 rises, and the rotating cover 43 gradually rotates. After reaching the sampling amount, the rotating cover 43 moves back to the initial position and blocks the mouth of the sampling bottle 4. For the other sampling bottles 4 that are not sampled, the rotating cover 43 blocks the opening of the sampling bottle 4, thereby reducing the probability of impurities and dust entering the sampling bottle 4.

[0055] Reference Figure 5 and Figure 7When the sampling volume is reached, without manually controlling the position of the float rod 52, the float 53 moves up to the top of the rotating cover 43, which means that the sampling volume is reached, and the plugging head 32 moves to the position of the water outlet 31 and blocks the water outlet 31. At this time, the leakage in the water pipe 3 is blocked, thereby controlling the sampling volume in a single sampling bottle 4. When heavy rain or flood disasters occur, the leakage suddenly increases and impacts the plugging head 32, and the plugging head 32 quickly moves down and seals the water outlet 31. The plugging head 32 drives the float 53 to move up, and the rotating cover 43 rotates to block the bottle mouth of the sampling bottle 4. After the heavy rain, the float 53 can be manually pushed to Rod 52 realizes resampling. Only rainwater or other water sources may remain in the sampling bottle 4 currently located at the sampling position. It is sufficient to switch to the next sampling bottle 4 for resampling, thereby controlling the sampling time point. For example, sampling and testing are carried out before the heavy rain, 48 hours after the heavy rain, 4 days after the heavy rain, and 7 days after the heavy rain, respectively, to explore the changes in the components of soil seepage liquid before and after the heavy rain. There is no need to dig out the collection box 1 again and bury it again for sampling according to the sampling time, thereby reducing the probability of damaging the soil layer. At the same time, heavy rain and other water sources will not pollute the collected liquid in all sampling bottles 4, thereby improving the convenience and accuracy of soil seepage liquid collection.

[0056] Reference Figure 2 , Figure 5 and Figure 7 When a single sampling bottle 4 completes sampling, the shielding cover 512 is first opened, and the floating rod 52 is manually pulled so that the floating rod 52 continues to be located above the rotating cover 43, and then the lifting rod 81 is moved so that the lifting rod 81 is located in the placement groove 133 close to the sampling bottle 4. At this time, the clamping piece 821 is inserted into the corresponding hanging ear 722, and the first magnetic plate 822 and the second magnetic plate 823 are adsorbed. Under the clamping and adsorption action, the lifting rod 81 and the base 72 are connected together, the handle 811 is turned and the lifting rod 81 is pulled horizontally, and the lifting rod 81 drives the base 72 to move, and the rolling The wheel 721 pushes the limit plate 731 to rotate. After the roller 721 is separated from the limit plate 731, the limit plate 731 rotates under the action of the torsion spring 732 and blocks the roller 721 of the next base 72. After the base 72 moves into the moving cavity 131, the lifting rod 81 is pulled upward to drive the base 72 and the sampling bottle 4 to move upward as a whole until the sampling bottle 4 is moved out. After the lid is covered, it can be taken back to the laboratory for testing, and then the lifting rod 81 is put back to the initial position, and the lifting rod 81 is connected to the next sampling bottle 4 located at the sampling position, so as to improve the convenience of removing the sampling bottle 4.

[0057] Reference Figure 7 , Figure 8 and Fig.10When the sampling bottle 4 in the collection box 1 is used up and a sampling bottle 4 needs to be added, the first magnetic plate 822 is removed from the lifting rod 81, and the clamping piece 821 is inserted into the ear 722 of the base 72 of the corresponding sampling bottle 4 to be placed, and the lifting rod 81 is pushed to drive the new base 72 and the sampling bottle 4 to move down as a whole to the connection between the collection chamber 11 and the moving chamber 131. At this time, the base 72 is located above the limiting plate 731, and the lifting rod 81 is pushed to move to the placement groove 133 near the sampling bottle 4, so that the base 72 moves to the top of the smooth section 712 of the sampling position, and then the lifting rod 81 is moved downward so that the roller 721 is located in the guide rail 71, and then the water Pulling the lifting rod 81 horizontally causes the clamping piece 821 to disengage from the hanging ear 722. Since there is no magnetic attraction between the lifting rod 81 and the base 72, the limit plate 731 can block the roller 721. Repeat the operation to place multiple sampling bottles 4. The next sampling bottle 4 to be placed pushes the sampling bottle 4 on the smooth section 712 to move to the inclined section 711. Repeat the process to complete the placement of all sampling bottles 4. During this process, the float 53 is always kept above the rotating cover 43, so as to achieve large-scale sampling of seepage liquid from the same soil position without digging out the sampling box, and without destroying the soil structure and without using a water pump, thereby improving the convenience of continuous sampling of seepage liquid from the same piece of soil.

[0058] Reference Figure 5 and Figure 7 The floating rod 52 is provided to improve the convenience of observing the collected amount in the sampling bottle 4, and the continuity and stop of sampling are realized through the linkage between the float 53 and the plugging head 32, and the soil layer will not be damaged during repeated sampling. There is no need to carry large equipment such as water pumps. After the sampling bottle 4 is taken out, the lid is covered and it can be taken back for testing directly, thereby improving the convenience of collecting soil seepage liquid.

[0059] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
