DETAILED DESCRIPTION

[0036] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0037] like Figures 1 to 4 As shown:

[0038] Embodiment 1: The present invention provides a field portable combined quantitative soil seepage collection device, comprising:

[0039] The seepage collection mechanism 1 comprises a soil leaching column assembly 11 and a seepage collection bottle assembly 12 arranged at the bottom of the soil leaching column assembly 11;

[0040] The soil leaching column assembly 11 comprises a soil leaching column body 111, the lower end of which is fixedly connected to a seepage fluid conduit 112, a filter screen 113 is arranged near the bottom wall of the soil leaching column body 111, a plurality of extension conduits 114 are arranged outside the soil leaching column body 111, one end of the extension conduit 114 extends into the interior of the soil leaching column body 111 and is horizontally fixedly connected to a soil solution sampling head 115, a sampling joint 116 is arranged at the other end of the extension conduit 114, and the intersection of the extension conduit 114 and the soil leaching column body 111 is sealed by glass glue 117;

[0041] The seepage collection bottle assembly 12 includes a seepage collection bottle body 121, and an air pressure balance pipe 122 is provided through the seepage collection bottle body 121. A silicone protective cover 123 is detachably provided on the upper end of the air pressure balance pipe 122.

[0042] The bottom of the permeate conduit 112 always extends into the interior of the permeate collection bottle body 121, and the air pressure balance pipe 122 extends into the interior of the permeate collection bottle body 121 near the bottom wall;

[0043] Among them, when using:

[0044] Step 1: insert the seepage fluid conduit 112 at the bottom of the soil leaching column body 111 into the seepage collection bottle body 121, insert the air pressure balance tube 122 into the seepage collection bottle body 121, and then fill the soil prepared in advance into the soil leaching column body 111, keeping the soil layer consistent with the natural soil structure;

[0045] Step 2: Connect the extension conduit 114 and the soil solution sampling head 115 to form a soil solution sampler as a whole, and finally insert the connected soil solution sampler into the sampling holes corresponding to different soil layers in the soil leaching column body 111 and seal them with glass glue 117;

[0046] Step 3: At the field monitoring point (the location where the original soil is obtained), dig in the vertical direction according to the height required by the device (usually 5-10 cm greater than the total height of the device for placement and adjustment), then place the portable combined quantitative soil seepage collection device into the dug pit, and then backfill the soil in sequence to ensure that the gap between the soil leaching column body 111 and the pit is filled and ensured to be stable, and at the same time, pay attention to expose the sampling joints 116 of the soil solution samplers of different soil layers to the soil surface;

[0047] The fourth step is to mark the location of the portable combined quantitative soil seepage collection device in the field, and the rest of the agricultural activities are consistent with the surrounding natural soil treatment methods;

[0048] Finally, according to different monitoring time points (different crop growth periods or dry and wet seasons), the soil solution of different soil layers is extracted through the sampling joint 116 with a vacuum sampler, and the volume is recorded and sent to the laboratory. If the runoff volume is large in the rainy season, after removing the silicone protective cover 123, the hose is passed through the air pressure balance tube 122 and extended into the inside of the seepage collection bottle body 121. The water pump is connected to the hose so that the liquid in the seepage collection bottle body 121 can be collected in batches, and the volume record and chemical analysis are done each time.

[0049] Specifically, the sampling joint 116 and the silica gel protective sleeve 123 are located on the ground surface, and the soil layer filled inside the soil leaching column body 111 is consistent with the external soil layer.

[0050] Specifically, the inside of the seepage collection bottle body 121 is also provided with a liquid level sensor, a turbidity sensor, a power module and a wireless data transmission module. The liquid level sensor is installed inside the seepage collection bottle body 121 for real-time monitoring of the collection amount of the seepage liquid, and sending the data to a remote receiving device through the wireless data transmission module to realize remote monitoring and data recording.

[0051] As can be seen from the above, the sampling connector 116 and the silicone protective sleeve 123 are located on the surface, which can facilitate the staff to perform sampling operations. The soil layer filled inside the soil leaching column body 111 is consistent with the external soil layer, which can maximize the reliability of the sample after sampling. The liquid level sensor is used to monitor the collection amount of the seepage liquid in real time, and the data is sent to the remote receiving device through the wireless data transmission module to achieve remote monitoring and data recording, so that the staff can extract the solution in the seepage collection bottle body 121 in time. The turbidity sensor can timely understand the changes in the content of suspended matter, colloidal particles or soluble substances in the soil seepage process. At the same time, the power module provides stable and reliable power support for the liquid level sensor, turbidity sensor and wireless data transmission module to ensure the normal operation of the entire monitoring system. Considering the complexity and uncertainty of the field environment, a combined power supply method of solar panels and batteries can be used to meet the needs of long-term monitoring.

[0052] like Figure 1 , 2 and 7:

[0053] Embodiment 2: This embodiment is basically the same as the previous embodiment, except that it further comprises a protection mechanism 2, including a protection component 21 disposed outside the seepage collection bottle component 12;

[0054] The protection assembly 21 includes a protection tube 211 , and a base 212 is provided at the bottom of the protection tube 211 ;

[0055] The protective tube 211 is made of high-strength, corrosion-resistant materials, such as stainless steel or special alloys, to ensure that it can maintain good physical properties and appearance integrity in various harsh environments. The protective tube 211 is cylindrical, with a smooth interior and no sharp edges and corners, to reduce friction and damage to the soil leaching column body 111 and the seepage collection bottle body 121;

[0056] The base 212 is also made of strong and durable materials, such as weighted cast iron or concrete, to increase the stability of the entire device; the upper surface of the base 212 is provided with a slot that matches the protective tube 211 and the seepage collection bottle body 121, ensuring that they can be firmly embedded in the base and are not easy to loosen.

[0057] The bottom of the base 212 may be designed to be a pointed cone or have an anti-skid pad to facilitate fixing the device in the soil and prevent sliding.

[0058] Specifically, the soil leaching column body 111 is slidably embedded in the protective tube 211, the protective tube 211 and the seepage collection bottle body 121 can be embedded in the base 212, the seepage collection bottle body 121 is located inside the protective tube 211, and the protective tube 211 can slide up and down along the air pressure balance tube 122.

[0059] As can be seen from the above, the design of the protective tube 211 allows the soil leaching column body 111 to be slidably embedded thereon, thereby facilitating installation and disassembly, and ensuring the stability of the soil leaching column body 111 in the vertical direction. The protective tube 211 also provides additional protection for the seepage collection bottle body 121. Placing it inside the protective tube 211 can effectively prevent the damage to the seepage collection bottle body 121 caused by external impact.

[0060] The stability of the entire device is further enhanced by the base 212. The soil leaching column body 111 and the seepage collection bottle body 121 can be embedded in the base 212. This design allows the entire device to remain stable in the horizontal direction and is not prone to tipping over.

[0061] The design that the protective tube 211 can slide up and down along the air pressure balance tube 122 makes it possible to conveniently adjust the position of the protective tube 211 when necessary, such as when taking samples, replacing seepage collection bottles, or performing other maintenance operations, without affecting the normal operation of the soil leaching column body 111 and the seepage collection bottle body 121.

[0062] like Figures 5 to 9 As shown:

[0063] Embodiment 3: This embodiment is basically the same as the previous embodiment, except that the seepage collection mechanism 1 further includes a positioning component 13;

[0064] The positioning assembly 13 includes a positioning block body 131, a positioning clamping edge 132 is provided at the upper end of one side of the positioning block body 131, a movable groove 133 is provided at the bottom of the positioning block body 131, a guide rod 134 is fixedly connected to the bottom of the positioning block body 131 in the movable groove 133, an L-shaped lever 135 and a spring 136 are slidably connected to the outer side of the guide rod 134, and a positioning inclined block 137 is fixedly connected to one side of the L-shaped lever 135;

[0065] The positioning edge 132 is provided at the upper end of one side of the positioning block body 131 and is designed to cooperate with the limit block 223 in the lifting assembly 22 to achieve precise vertical positioning;

[0066] The movable groove 133 is located at the bottom of the positioning block body 131, providing a movable space for the L-shaped lever 135 and the spring 136, allowing them to perform necessary movements;

[0067] The guide rod 134 is fixedly connected to the movable groove 133 at the bottom of the positioning block body 131, providing a guide for the L-shaped lever 135 to ensure its stability and directionality during movement;

[0068] The L-shaped lever 135, the spring 136 and the guide rod 134 are slidably connected to each other in a limited position. The user can change the position of the positioning bevel 137 by operating the L-shaped lever, thereby achieving separation from the positioning groove 224.

[0069] The positioning bevel block 137 is fixedly connected to one side of the L-shaped lever 135 and is designed with an inclined surface to facilitate quick and stable engagement with the positioning groove 224. Under the action of the spring 136, the positioning bevel block 137 can automatically extend and engage with the positioning groove 224 to achieve stable positioning.

[0070] Specifically, the protection mechanism 2 further includes a lifting component 22 installed inside the protection component 21;

[0071] The lifting assembly 22 includes a threaded rod 221, a slider 222 connected by a thread is arranged on the outer side of the threaded rod 221, one end of the threaded rod 221 is located on the outer side of the protective tube 211 and is fixedly connected to a rotating handle, a limit block 223 is fixedly connected to the upper end of one side of the slider 222, and a positioning groove 224 is also opened on one side of the slider 222;

[0072] The protection assembly 21 further includes a support block 213 disposed inside the protection cylinder 211;

[0073] The threaded rod 221 is the core component of the lifting assembly 22, and is threadedly connected to the slider 222 through the threads on its outer side. When the threaded rod 221 rotates, it can drive the slider 222 to move in the vertical direction.

[0074] The rotating handle is fixedly connected to one end of the threaded rod 221 and is located outside the protective tube 211, so that the user can manually operate to rotate the threaded rod 221;

[0075] The slider 222 is connected to the threaded rod 221 through a thread, and moves vertically under the drive of the threaded rod 221. The limit block 223 fixedly connected to the upper end is used to cooperate with the positioning edge 132 to achieve vertical positioning;

[0076] The limit block 223 is fixedly connected to the upper end of one side of the slider 222, and is used to be embedded in the positioning edge 132 to ensure accurate positioning;

[0077] The positioning groove 224 is provided on one side of the slider 222 and cooperates with the positioning bevel block 137 to achieve a stable connection between the slider 222 and the positioning block body 131 .

[0078] Specifically, the threaded rod 221 is fixedly installed on the protective tube 211 and the support block 213 through bearings. The rotation of the threaded rod 221 can drive the slider 222 to move, the limit block 223 can be embedded in the positioning edge 132, and the spring 136 can drive the positioning bevel block 137 to extend out of the positioning block body 131 and be embedded in the positioning groove 224.

[0079] From the above, we can see that during installation

[0080] Step 1: First, slide the soil leaching column body 111 from the bottom of the protective tube 211, and make the limit block 223 and the positioning edge 132 engage, and at the same time, the positioning inclined block 137 will be driven by the spring 136 to be embedded in the positioning groove 224, so as to achieve the effect of fixed connection;

[0081] Step 2: Connect the extension conduit 114 and the soil solution sampling head 115 to form a soil solution sampler as a whole, and finally insert the connected soil solution sampler into the sampling holes corresponding to different soil layers in the soil leaching column body 111 and seal them with glass glue 117;

[0082] Step 3: Slide the seepage collection bottle body 121 from the bottom of the protective tube 211 and insert the seepage liquid conduit 112 into the inside of the seepage collection bottle body 121, and then insert the protective tube 211 and the seepage collection bottle body 121 into the base 212 to complete the installation;

[0083] When adjusting the height, adjusting the rotating handle can make the threaded rod 221 rotate on the protective tube 211 and the support block 213. The rotation of the threaded rod 221 will cause the slider 222 to move up and down. The up and down movement of the slider 222 will cause the positioning block body 131 to drive the soil leaching column body 111 to move up and down, thereby adjusting the height of the soil leaching column body 111 relative to the soil layer, so that the soil layer filled inside the soil leaching column body 111 is consistent with the natural soil structure.

[0084] Application Process:

[0085] 1. Equipment preparation and installation

[0086] Preparation stage:

[0087] Confirm that all components (soil leaching column assembly, seepage collection bottle assembly, protection mechanism, positioning assembly, etc.) are intact.

[0088] Check whether the electronic devices such as liquid level sensor and turbidity sensor are properly installed and connected to the power module and wireless data transmission module.

[0091] The soil leaching column body 111 is slidably inserted from the bottom of the protective tube 211 , and the limiting block 223 is ensured to be engaged with the positioning edge 132 , and the positioning inclined block 137 is inserted into the positioning groove 224 under the drive of the spring 136 to achieve a stable connection.

[0092] The extension conduit 114 and the soil solution sampling head 115 are connected to form a whole soil solution sampler, and then the connected soil solution sampler is inserted into the sampling holes corresponding to different soil layers in the soil leaching column body 111 and sealed with glass glue 117.

[0096] Overall device fixing and height adjustment:

[0097] The protective tube 211 and the seepage collection bottle body 121 are snapped onto the base 212 to ensure that the device is stable.

[0098] If the height of the soil leaching column body 111 relative to the soil layer needs to be adjusted, the threaded rod 221 can be rotated by rotating the rotating handle, thereby driving the slider 222 to move up and down, and driving the soil leaching column body 111 to move up and down to a suitable position.

[0099] Place the entire device into a pre-dug pit (the pit depth should be 5-10 cm greater than the total height of the device), and backfill the soil in sequence to ensure that the gap between the soil leaching column body 111 and the pit is filled and stable.

[0100] Special attention should be paid to exposing the sampling joints 116 of the soil solution samplers of different soil layers to the soil surface to facilitate subsequent sampling operations.

[0101] 2. Field Monitoring and Sampling

[0106] Based on the monitoring results, timely evaluate the soil seepage conditions and prepare a sampling plan.

[0107] Sampling operation:

[0108] At different monitoring time points (such as different crop growth periods or dry and wet seasons), a vacuum sampler is used to extract soil solutions from different soil layers through the sampling joint.

[0109] The sample volume was recorded and the sample was sent to a laboratory for analysis.

[0110] 3. Maintenance and Adjustment

[0111] Regular inspection:

[0112] Regularly check whether all parts of the device are intact, especially whether the filter screen 113 of the soil leaching column body 111 is blocked and whether the seepage fluid conduit 112 is unobstructed.
