This invention relates to the field of brine drainage technology for salt caverns, and provides a wellbore structure for brine drainage from salt caverns, comprising at least: a gas injection well located above the salt cavern and extending from the surface into the salt cavern; a first row of brine wells located above the salt cavern and extending from the surface to the bottom of the salt cavern, with drill pipes installed in the first row of brine wells; and a second row of brine wells located outside the boundary of the salt cavern and extending from the surface beyond the bottom of the salt cavern, with the well body of the second row of brine wells extending towards the first row of brine wells so that the drill pipes at least partially extend into the second row of brine wells. In this wellbore structure for brine drainage from salt caverns, the first and second rows of brine wells are designed with vertical alignment, wherein the second row of brine wells is located at the edge of the salt cavern and extends towards the first row of brine wells via a double-angle drilling method, forming a connection with the first row of brine wells. This allows for the complete drainage of brine from the salt cavern, increasing the gas storage space.

The utility model provides a powder feeding device for inductor integral forming equipment, which comprises a hopper, a strip-shaped feed opening is arranged at the bottom of the hopper, and a feed roller for quantitative discharge is mounted at the feed opening; a stirring mechanism is mounted on the inner side of the bottom of the hopper and used for stirring materials collected at the bottom of the hopper, so that the materials are uniformly distributed; a vibration motor is installed on the outer side of the bottom of the hopper and used for promoting materials to enter a material groove of the discharging roller to form a unified compaction effect and further used for promoting the discharging roller to discharge materials completely. Materials can be effectively stirred, the vibration effect is provided, and it is ensured that the material groove is completely filled with the materials; and complete blanking can be ensured through vibration.
