Description

Technical Field

[0001] The utility model belongs to the technical field of groundwater restoration, and specifically relates to a drug delivery device for groundwater restoration and management. Background Art

[0002] Groundwater remediation refers to the use of extraction, gas extraction, bioremediation, infiltration reaction wall and chemical remediation technologies to restore contaminated groundwater to its original water quality. The delivery of reducing agents to groundwater belongs to the chemical remediation-related technology. With the continuous development of the social industrialization process, wastewater discharge, industrial waste residue, agricultural irrigation, landfill leakage, damage to petrochemical raw material transportation pipelines and storage tanks, etc. may cause groundwater pollution. In addition, groundwater resources are an important part of freshwater resources and the main source of drinking water in my country. Therefore, the use of groundwater remediation drug delivery devices to deliver purification and decontamination liquid to groundwater to carry out groundwater pollution control and remediation work is of great significance to the sustainable utilization of groundwater resources.

[0003] When repairing groundwater, a drug delivery device is needed. For example, Chinese utility model patent CN220573218U discloses a drug delivery device for groundwater repair and management. The drug delivery device for groundwater repair and management pushes the drug delivery cart to the drug delivery location, and uses the first motor to drive the active gear rod. The active gear rod engages and drives two driven gear rods to make the two threaded screws rotate synchronously, driving the second motor, the connecting shaft and the drill rod to move up and down. When the drill rod moves to a suitable height, the second motor drives the spiral assembly and the connecting rod at the same time, so that the drill rod rotates at high speed to drill down the soil layer, and then uses a pump to send the decontamination liquid in the medicine storage box into the internal cavity of the connecting shaft cylinder through the telescopic tube. The spiral wheel performs secondary stirring at the same time, and then sends it into the drill rod through the filter mesh plate to evenly spray it to the groundwater at high speed, thereby achieving the effect of drilling holes in the soil layer and delivering drugs at the same time.

[0004] Although the above-mentioned prior art can achieve the effect of drilling holes in the soil layer and injecting medicine at the same time, the device requires two power devices to output separately for rotating holes and stirring the medicine solution, which wastes power transmission and increases production and use costs.
