[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0025] Example 1;

[0026] Please see Figure 1 , Figure 2 , Figure 3 and Figure 4This utility model provides a technical solution: a field saline-alkali contaminated soil improvement device, which is mainly used in field saline-alkali contaminated soil improvement scenarios. It includes a solar panel 1, with a battery 3 connected to the lower end of the solar panel 1 via wires. Both ends of the upper surface of the battery 3 are fixedly connected to pull rods 8. A device box 9 is fitted onto the outer surface of the battery 3. A heat dissipation vent 10 is provided on one side of the device box 9, and a filter screen 11 is clipped onto the inner wall of the heat dissipation vent 10. A box cover 12 is connected to the upper end of the device box 9 via a hinge. A handle 13 is detachably connected to the middle of the upper end of the box cover 12. The lower part of the device box 9... The surface is detachably connected to the upper end of the placement plate 14. The output end of the battery 3 is connected to the electrochemical remediation mechanism 2 via a wire. The electrochemical remediation mechanism 2 includes a first soil tank 201. Both ends of the first soil tank 201 are bolted to an electrolyte tank 203. The contact surfaces of the first soil tank 201 and the electrolyte tank 203 are provided with silicone pads 202. An ion membrane 204 is provided between the two silicone pads 202 on the same side. The inner walls of the two electrolyte tanks 203 are detachably connected to a first electrode plate 209. The input end of the first electrode plate 209 is connected to the output end of the battery 3 via a wire. The electrolyte tank 203... A transmission pipe 205 is detachably connected to the side of the solar panel 1. A peristaltic pump 206 is detachably connected to the other end of the transmission pipe 205. A display panel 207 is provided on the upper end of the peristaltic pump 206. A control button 208 is provided on the side of the upper end of the peristaltic pump 206 near the display panel 207. A support frame 5 is connected to both ends of the center of the solar panel 1 through an adjustment mechanism 4. The adjustment mechanism 4 includes a connecting shaft 401, which is installed horizontally through the center of the solar panel 1. Bearing seats 402 are sleeved on both ends of the connecting shaft 401. The lower end of the bearing seat 402 is connected to the upper end of the support frame 5 by bolts. One end of the connecting shaft 401 passes through one of the bearing seats 402 and is connected to a limiting plate 403. The other end of the connecting shaft 401 passes through another bearing seat 402 and is threadedly connected to a handle 404. A positioning plate 406 is provided on the side of the bearing seat 402 adjacent to the limiting plate 403. Multiple through holes are provided on the surfaces of the positioning plate 406 and the limiting plate 403. A pin 405 is inserted through any one of the corresponding through holes. Mounting plates 6 are symmetrically welded to both ends of the bottom of the support frame 5. Fastening bolts 7 are provided at the four corners of each mounting plate 6. A placement plate 14 is welded to the middle of the lower surface of one of the support frames 5.

[0027] Through the above technical solution, when the equipment is used indoors, the support frame 5 is first fixed in a suitable position by the mounting plate 6 and fastening bolts 7. At the same time, the solar panel 1 is connected to the bearing seat 402 by the connecting shaft 401. When the operator holds the handle 404 and applies external force, the connecting shaft 401 rotates. Due to its linkage effect, it synchronously drives the connected solar panel 1 and the limiting plate 403 to rotate. When the solar panel 1 reaches a suitable light position, the pin 405 is inserted into the limiting plate 403 and the positioning plate 406 for mechanical limiting. Through mechanical limiting, the connecting shaft 401 is effectively locked, ensuring that the solar panel 1 remains stable in the predetermined position and avoiding displacement due to external disturbance. After the solar panel 1 converts light energy into electrical energy, it is transmitted to the storage battery 3 in real time for storage. Through the coordinated arrangement of the first soil tank 201, electrolyte tank 203, first electrode plate 209 and ion membrane 204, after the storage battery 3 powers the first electrode plate 209, the first... An electric field is generated inside the soil tank 201, and an electrolytic reaction occurs in the electrolyte inside the electrolyte tank 203. The generated ions migrate directionally under the driving force of the electric field. Positive and negative ions in the soil move towards the electrodes of corresponding polarities under the action of the electric field force and selectively pass through the ion membrane 204, eventually entering the electrolyte tank 203, reducing the content of harmful ions in the contaminated soil. At the same time, harmful ions are stored in the corresponding electrolyte tank 203. During the improvement process, the operator can precisely adjust the delivery volume and speed of the peristaltic pump 206 by operating the control button 208. During the soil improvement process, the electrolyte can circulate in the electrolyte tank 203. When the peristaltic pump 206 is working, the display panel 207 on its upper end can display its working status in real time. When the soil is improved by this device, the soil moisture content is not less than 10%. The battery 3 can provide a voltage of 40V to 60V for the equipment, providing reliable power support for the normal operation of the equipment.

[0028] Meanwhile, the device box 9 protects the internal components such as the battery 3 from damage caused by external factors such as dust and rain. When the battery 3 is running, the heat generated by it can be discharged through the heat dissipation vent 10 on one side of the device box 9. The filter 11 inside the heat dissipation vent 10 can filter dust in the outside air to prevent it from entering the device box 9. At the same time, the box cover 12 can seal the device box 9, further protecting the battery 3 inside. The handle 13 on the top of the box cover 12 not only makes it easy for staff to open the box cover 12 for inspection and maintenance, but also makes the entire device box 9 easier and more convenient to move, greatly improving the practicality of the equipment in the field. In addition, the pull rod 8 on the top of the battery 3 can provide a gripping point for staff when the battery 3 needs to be replaced, making it easy for staff to take the battery 3 out of the device box 9 for replacement.

[0029] Example 2;

[0030] Please see Figure 5 , Figure 6 and Figure 7 Compared with Embodiment 1, the difference in this embodiment is that the electrochemical remediation mechanism 2 and the second soil tank 210 have different structures than those in Embodiment 1. The electrochemical remediation mechanism 2 also includes a second soil tank 210. The inner wall of the second soil tank 210 is detachably connected to a second electrode plate 211. The input end of the second electrode plate 211 is connected to the output end of the battery 3 through a wire.

[0031] Through the above technical solution, when the device is used outdoors, the support frame 5 is securely installed above the soil to be improved by fastening bolts 7 and mounting plate 6. Then, the second soil trough 210 is placed at the lower end of the support frame 5 in the soil area to be improved, so that the solar panel 1 can be erected on the top of the second soil trough 210 through the support frame 5, forming an efficient energy collection layout. At the same time, the staff adjusts the angle of the solar panel 1 in this embodiment by following the angle adjustment steps of the first embodiment, so that the solar panel 1 reaches a suitable elevation angle and can obtain sufficient sunlight. After the solar panel 1 converts light energy into electrical energy, it is transmitted to the storage battery 3 in real time for storage. Since the storage battery 3 is connected to the second electrode plate 211 through wires, it can supply power to the second electrode plate 211, so that an electric field is generated inside the second soil trough 210. Under the driving force of the electric field, harmful ions migrate in a direction and move to the electrodes of corresponding polarity, thereby improving the soil in the second soil trough 210. When the soil is improved by this device, its soil moisture content is not less than 10%.

[0032] The outdoor battery 3 can generate a voltage of 110V to 220V, providing reliable power support for the normal operation of the equipment in the field. The second soil trough 210 has a diameter of 1.6m. 1m The 50cm height significantly increases the volume of soil treated in a single application, enabling efficient improvement of large areas of soil in field environments and fully meeting practical engineering needs. The support frame 5 has a 2m specification. 1.5m The height and width of 80cm ensure that there is a suitable space between the solar panel 1 and the second soil tank 210, avoid mutual interference, and allow the solar panel 1 to maintain a good elevation angle to suit the light conditions of different regions. This height also facilitates the installation, debugging and daily maintenance of the equipment by the operators.

[0033] All electrical components mentioned in this article are connected to an external main controller and 220V AC mains power, and the main controller can be a conventional known device such as a computer that can control it.
