Abstract: Provided are a centrifugal battery liquid injection mechanism and a liquid injection method thereof. The centrifugal battery liquid injection mechanism comprises a liquid injection device and a driving device, the liquid injection device is provided with a piston mechanism and a liquid outlet head capable of being opened and closed, and one end of the liquid injection device close to the liquid outlet head is further provided with a liquid injection port capable of being opened and closed; and the liquid injection port is used for injecting a wetting liquid into the liquid injection device. The liquid injection device is connected with a to-be-wetted device through the liquid outlet head, so as to inject the wetting liquid into the to-be-wetted device. The driving device is connected with the to-be-wetted device for driving the to-be-wetted device to move.

Abstract: An interaction processing method and apparatus for an information flow includes displaying the information flow in an information flow region. The interaction region is inserted into the information flow and an interaction material corresponding to the interaction region is displayed in a search region. In response to an interaction operation for the interaction region, an interaction process based on the interaction material in the interaction region is displayed.

Abstract: The invention discloses a retrievable sand consolidation anchor head prestressed anchor rod, an anchoring jack and an application method thereof, and belongs to the technical field of geotechnical engineering. The retrievable sand-consolidated anchor head pre-stressed anchor includes a bolt body 6, a rigid frame 5, a load member 1, a sand column 2, a pressure receiving member 4, a cut-off member 3, and an anchor pier 8. The anchoring jack includes a force transmitting frame 12, a first guiding plate 25, a second guiding plate 28, and a housing 13. The application method includes an anchoring method using the retrievable sand-consolidated anchor head prestressed anchor rod and a method of recovering the retrievable sand-consolidated anchor head pre-stressed anchor rod. After the anchoring of the reclaimed sand-consolidated anchor head pre-stressed anchor rod, the bolt body can be recovered and reused, and the operation is simpler and more environmentally friendly.
