Description

Technical Field

[0001] This invention relates to the field of soil remediation technology, specifically to an in-situ activation and remediation device for soil microbial agents. Background Technology

[0002] Soil is a vital carrier of the ecological environment and a fundamental element for agricultural production and ecological balance. With the continuous advancement of industrial and agricultural production activities, some areas have experienced organic matter residues and the accumulation of harmful substances in the soil, impacting soil ecological structure, crop growth environment, and ecosystem security. In-situ activation and remediation of soil microbial agents is a green ecological remediation technology developed based on the principles of soil microecology. This technology focuses on in-situ treatment, eliminating the need for large-scale soil transportation and off-site processing. By adding functional microbial agents to the target soil, supplemented by appropriate agent diffusion and activation methods, the metabolic and reproductive activities of functional microorganisms are fully stimulated. Utilizing the degradation, transformation, and passivation effects of microorganisms on harmful substances in the soil, soil pollutants are gradually eliminated, soil microbial community structure is optimized, and the soil's natural purification capacity and tillage performance are restored. This technology adheres to the concept of eco-friendly remediation, minimizes disturbance to the surrounding environment, and aligns with the needs of green and sustainable governance, making it an important technical approach in the field of contaminated soil ecological remediation.

[0003] Existing traditional soil remediation technologies have significant shortcomings. They require pre-drilling, with large-scale operations necessitating the drilling of hundreds or even thousands of holes. This relies on drilling rigs for each hole, resulting in lengthy construction periods and high labor costs. Furthermore, the need to assemble and connect pipelines, valves, and probes one by one leads to high material and installation costs. The overall construction process involves multiple independent steps, such as drilling, pipeline laying, and equipment transportation, requiring the coordinated operation of multiple sets of equipment. This fragmented and cumbersome process, coupled with redundant and complex equipment, results in the core drawbacks of numerous construction steps, low operational efficiency, high labor and material costs, and complex equipment requirements.

[0004] Therefore, a solution is needed. Summary of the Invention

[0035] Solution Analysis: 1. Highly efficient integration, significantly improving operational efficiency. Integrated operation process: This equipment integrates the three core processes of static pressure penetration, bacterial liquid spraying, and in-situ mixing into one vehicle-mounted device, completely eliminating the cumbersome process of "drilling → pipeline laying → multi-equipment collaboration" in traditional technology.

[0036] Quick switching of operating heads: Through the lateral movement of the transmission mechanism 3 and the vertical lifting of the repair mechanism 4, the pressure head, spray head and mixing head can be quickly switched, and the single-hole operation cycle is greatly shortened, which is especially suitable for the efficient treatment of large-area contaminated sites.

[0037] 2. Precise and controllable, improving repair quality. Precise depth control: The hydraulic cylinder 42, in conjunction with the sensing probe 44, can accurately locate the depth of the most severely contaminated soil layer, ensuring that the repair effect reaches the lesion directly.

[0038] Uniform bacterial agent diffusion: The wide-angle nozzle 415 injects the bacterial solution into the bottom of the hole, and the centrifugal stirring bar 434 rotates at high speed to fully mix the bacterial solution with the soil, effectively expanding the remediation radius of a single hole and avoiding the problem of uneven distribution of the bacterial agent.

[0039] Intelligent sensing: The application of tactile sensor 432 and sensing probe 44 enables automated perception and feedback during the operation process, improving operational accuracy and safety.

[0040] 3. Cost optimization and reduction of resource consumption. Reduced labor and consumables: Eliminating the need for extensive manual labor in drilling, pipeline laying, and equipment transportation significantly reduces labor costs. Simultaneously, it avoids the use and waste of large quantities of pipes, valves, and other consumables common in traditional technologies.

[0041] Reduced equipment investment: One piece of equipment can complete all operations, eliminating the need to purchase multiple sets of equipment such as drilling rigs and spraying trucks, which greatly reduces the equipment investment and maintenance costs of the project.

[0042] 4. Environmentally friendly with minimal ecological disturbance In-situ remediation: The entire process is carried out on-site, without the need for large-scale earthwork transportation, minimizing damage to soil structure and the surrounding ecological environment.

[0043] Green concept: Relying on the natural degradation of microbial agents, there is no secondary pollution, which is in line with the concept of green and sustainable ecological restoration.

[0044] 5. Easy to operate and highly adaptable Mobile and flexible: The vehicle-mounted platform design allows for easy relocation and adaptability to different terrains and site conditions.

[0045] High degree of automation: The core operation process can be completed automatically by motors and hydraulic cylinders 42, which is simple to operate and reduces the requirements for the professional skills of operators.

[0046] Working principle: During operation, first, threaded connector 418 is passed through pipe hole 47 from left to right and mates with threaded connector 414. Then, the moving box 314 is positioned in the rear half of the conveyor box 35. Next, the hydraulic cylinder 42 is activated, driving the threaded pressure head 43 to press into the ground until the sensing probe 44 detects the deepest point requiring repair, at which point it stops and retracts to its original position. The next step involves motor 312 driving transmission roller 37 to rotate via shaft 311. This rotation, through the meshing between toothed chain 38 and toothed chain 310, causes toothed chain 310 to rotate, aligning the top of toothed chain 38 with the bottom of toothed chain 310. This causes the moving box 314 to move forward one-third of its length before stopping. Subsequently, driven by motor 2 48, the lead screw 1 49 rotates, and the fixed block 1 412, along with the infusion tube 1 413, moves downward until it is below the top of the pressure hole. The solenoid valve 416 is then opened, and the bacterial solution is sprayed from top to bottom into the pressure hole through the infusion tube 2 417, the infusion tube 1 413, and the wide-angle nozzle 415 until it reaches the bottom of the pressure hole. After a certain amount has been filled, the fixed block 1 412 returns to its original position. Then, the moving box 314 is moved forward by one-third of its length and stops. Then, driven by motor 3 421, the lead screw 2 422 rotates, and the fixed block 2 425, along with motor 429 and the rotating rod 430, descends until the touch sensor 432 senses the bottom of the pressure hole. Then, motor 429 drives the rotating rod 430 to rotate rapidly. Under the influence of centrifugal force, each stirring bar 434 expands outward until it reaches ninety degrees, which rapidly stirs the already softened soil at the bottom, facilitating the diffusion of the bacterial solution in all directions. After rotation stops, the mixing bar 434 automatically closes due to loss of centrifugal force, and then the fixing block 425 returns to its original position. Finally, the moving box 314 returns to its original position to complete one repair cycle, which is convenient, quick, and saves time and effort. Afterwards, the equipment vehicle 1 moves a distance and continues to repeat the above workflow until the repair work on the entire land is completed.

[0047] Technical effects of implementing this solution: This solution, through its integrated vehicle-mounted design, precise and controllable operating procedures, and efficient microbial agent diffusion mechanism, fundamentally solves the pain points of traditional soil remediation technologies, such as cumbersome procedures, low efficiency, and high costs. It not only significantly improves remediation efficiency and quality but also substantially reduces economic costs and environmental disturbance.
