The present invention discloses a large-section water-blocking conductor for a submarine cable. The large-section water-blocking conductor comprises a supporting core; n round wire stranded layers are arranged at the outer side of the supporting core, wherein n is a natural number greater than or equal to 1; a plurality of round wire compressing stranded layers are arranged at the outer side of the round wire stranded layers; the round wire pressing stranded layers and shaped wires stranded layers are arranged in a staggered manner; and water-blocking layers are arranged between the round wire stranded layers, the round wire pressing stranded layers and the shaped wires stranded layers. The compressing degree of the large-section water-blocking conductor is improved, and the overall deformation of the large-section water-blocking conductor is more uniform, and therefore, a water blocking effect can be effectively improved. The large-section water-blocking conductor has the advantages of simple structure, low transformation cost, long service life and the like.

The invention relates to the technical field of articles for daily use, and discloses an auxiliary fastening mechanism for a thermos bottle plug, which comprises a plug body, an adjusting cavity is formed in the middle of the inner cavity of the plug body, a pull rod movably sleeves the middle of the plug body, a vent groove is formed in the middle of the pull rod, and an auxiliary block positioned on the outer side of the lower end of the pull rod movably sleeves the lower end of the adjusting cavity. The lower end of the auxiliary block is fixedly connected with an adjusting block, and the middle of the adjusting block is provided with an air suction groove communicating the vent groove with the lower portion of the plug body. Through the arrangement of an automatic pressurizing mechanism, when the interior of the thermos bottle is gradually cooled, internal air pressure is rapidly reduced, and a bottle plug is adsorbed to a bottle opening, under the action that negative pressure and a ball block the lower end of a vent groove, a pull rod moves downwards, and after an ejector rod ejects the ball upwards, an inner cavity of the bottle is communicated with the outside through the vent groove; therefore, outside air can quickly flow into the bottle to be pressurized, and the situation that the bottle plug cannot be pulled out due to the fact that the air pressure in the bottle is small is avoided.
