Detailed Description

The underground water restoration agent injection device of the present invention will be further described with reference to fig. 1, fig. 2 and fig. 3.

Example 1

The utility model discloses a groundwater remediation medicament injection device, including fixing base 1 and well casing 2, the inside at the monitoring well is installed to its well casing 2, fixing base 1 is being connected to the top fixed connection of well casing 2, gear motor 3 is being installed on the upper portion of fixing base 1, well casing 2 embeds there is the threaded shaft pole 4 of being connected with 3 transmissions of gear motor, threaded shaft pole 4 is going up the screw connection and is being poured into dish 5, the inside equipartition of pouring into dish 5 is pouring medicine propeller 6 of radial movement, the equipartition is adding medicine filling hole 7 on the lower part pipe wall of well casing 2, it is feeding through on the propeller 6 with the pencil 11 to pour medicine.

Example 2

The utility model discloses a groundwater remediation medicament injection device, including fixing base 1 and well casing 2, the inside at the monitoring well is installed to its well casing 2, fixing base 1 is being connected to the top fixed connection of well casing 2, gear motor 3 is being installed on the upper portion of fixing base 1, well casing 2 embeds there is the threaded shaft pole 4 of being connected with 3 transmissions of gear motor, threaded shaft pole 4 is going up the screw connection and is being poured into dish 5, the inside equipartition of pouring into dish 5 is pouring medicine propeller 6 of radial movement, the equipartition is adding medicine filling hole 7 on the lower part pipe wall of well casing 2, it is feeding through on the propeller 6 with the pencil 11 to pour medicine. The medicine injection propeller 6 is driven to move radially through the pneumatic cylinder 12, the threaded shaft rod 4 is driven to rotate through the speed reduction motor during medicine adding, the position of the injection disk 5 is adjusted, then the pneumatic cylinder 12 is opened, the medicine injection propeller 6 is pushed out from the injection disk 5, the medicine injection end at the front end of the medicine injection propeller 6 is in butt joint with the medicine adding injection hole 7, and then a medicine adding pump at the ground end of the medicine adding pipe 11 is started or pressurized to add medicine through pressure. Two sliding rods 8 parallel to the threaded shaft rod 4 are fixed on the fixed seat 1, and the injection disk 5 is in sliding connection with the sliding rods 8, so that the injection disk 5 can only move longitudinally along the sliding rods 8.
