Description

Technical Field

[0001] The utility model relates to the technical field of groundwater pollution control, in particular to a drug placement device for groundwater pollution repair. Background Art

[0002] When treating groundwater pollution, a chemical injection device is needed to inject chemicals into the water body deep below the surface.

[0003] Chinese patent publication number CN 217148606 U discloses a groundwater pollution control dosing device, comprising a vertically arranged central tube comprising a tube body and end caps. The tube body is closed at the bottom and open at the top. The end caps are detachably connected to the top opening of the tube body. A drug supply tube is connected to the end cap, communicating with the inner cavity of the tube body. The end of the drug supply tube, remote from the end cap, is connected to a drug supply box containing a pollution control liquid. The drug supply tube is provided with a water pump. The tube body is provided with a plurality of drug dispensing devices, comprising a drug delivery tube and a drug dispensing tray. The drug delivery tube is connected to the central tube at one end and to the drug dispensing tray at the other end. The drug dispensing tray is arranged perpendicular to the drug delivery tube, and the surface of the drug dispensing tray, remote from the drug delivery tube, is provided with an array of drug dispensing holes. This device is capable of dispensing drugs into groundwater, which has the advantage of fully mixing the drug solution with the groundwater.

[0004] The above device has the following problems: 1. It does not have a drilling structure, and when administering the medicine, it is necessary to carry an additional drilling device with it, which is not convenient to use;

[0005] 2. When near groundwater, the nearby soil is relatively moist and easily adheres to the one-way valve, causing the device to be unable to completely deliver the agent into the water and soil, resulting in waste. Even if the one-way valve is severely blocked, it will lead to the inability to deliver the agent.

[0006] In order to solve the above problems, this application proposes a device for injecting chemicals for groundwater pollution remediation. Utility Model Content

[0018] Through the two-way driving mechanism and the dosing mechanism, the ejection cylinder can push the agent out of the drug storage tank when the opening and closing piece is opened, so that it is pushed into the water body, avoiding the possibility that the agent may stick to the inside of the drug storage tank after contact with the water body, increasing the contact effect between the groundwater pollution remediation agent and the groundwater, making it melt more thoroughly. At the same time, the ejection structure can further reduce the risk of the dosing port being blocked. BRIEF DESCRIPTION OF THE DRAWINGS

[0040] Working principle:

[0041] After the medicine storage tank 405 is filled with the groundwater pollution remediation agent, the electric telescopic rod 3 drives the fixed box 402 and the conical head 403 to descend, and the infrared transmitter 604 is used to start the motor 603 to drive the conical head 403 to rotate, so that the fixed box 402 and the conical head 403 descend while the spiral blades 404 on the outside of the conical head 403 dig a hole, thereby eliminating the need for additional drilling equipment. When the fixed box 402 and the conical head 403 are lowered into the groundwater, the infrared transmitter 604 controls the output shaft of the motor 603 to rotate in the opposite direction of drilling, so that the ratchet 605 and the pawl 607 cooperate to drive the limit plate 606 to rotate, thereby driving the threaded rod 406 and the active disk 507 to rotate, so that the threaded rod 406 drives the ejection cylinder 407 under the action of the thread. At this time, the two sides of the ejection cylinder 407 cannot rotate due to the cooperation of the limit groove 408 and the limit block 409. , so that when the threaded rod 406 rotates, the pushing cylinder 407 moves vertically downward in the medicine storage tank 405, pushing the groundwater pollution remediation agent in the medicine storage tank 405 downward. At the same time, the active disk 507 drives the rotating disk 502 to rotate, so that the rotating disk 502 drives the opening and closing piece 503 to rotate. At this time, since the bottom of the opening and closing piece 503 is limited by the slide groove 504 and the fixed shaft 505, the opening and closing piece 503 slides along the slide groove 504 under the action of the fixed shaft 505, so that the opening and closing piece 503 spreads in a circular shape to the surrounding areas, and no longer closes the bottom of the medicine storage tank 405. At this time, the pushing cylinder 407 is in a descending state under the action of the threaded rod 406, thereby realizing that the pushing cylinder 407 pushes the groundwater pollution remediation agent downward while the opening and closing piece 503 is opened synchronously, sending the groundwater pollution remediation agent into the groundwater, and only one motor is needed, which reduces the manufacturing cost of the device.

Therefore, the appended claims are intended to be interpreted as including the preferred embodiments and all changes and modifications that fall within the scope of the present invention.
