This invention belongs to the field of sanitary ware technology and discloses a low-consumption vacuum toilet pulse flushing mechanism and sewage discharge method; it includes a toilet body, a water tank fixedly mounted on the toilet body, a toilet seat rotatably hinged to the toilet body, two independently detected infrared sensors fixedly mounted on the toilet body, and five water outlets arranged in a circumferential pattern on the inner wall of the toilet body's rim, each water outlet specifically arranged at a 35-degree angle to the inner wall of the toilet body; the five 35-degree circumferential water outlets spray a vortex thin water film with a water pressure of 0.35-0.5MPa, forming a full-coverage lubricating layer on the inner wall of the toilet in advance, preventing feces from directly adhering to the ceramic glaze from the source, eliminating the need for subsequent water replenishment and achieving water-saving pre-lubrication of the wall upon sitting. The water outlets are all designed with a 35-degree inner wall angle, and the water flow is sprayed out along the tangent of the inner wall of the rim, forming a closed-loop vortex water flow. Compared with vertical water outlets, the flushing coverage area of ​​the inner wall is comprehensively improved, and no dirt in the dead corners of the rim is missed.

This invention relates to a live-installable anti-adhesion isolation clamp and method for transmission line sub-conductors, belonging to the field of transmission line operation and maintenance technology. The technical solution is as follows: a lightweight heavy-duty drone (22) lifts the isolation clamp (24) and flies it above the double-split sub-conductors, with the two split sub-conductors (21) entering the upper and lower clamps of the isolation clamp respectively; after monitoring the split sub-conductors entering the upper or lower trench, the drone locks the split sub-conductors within the upper and lower trenches; the installation device separates from the isolation clamp, and the installation device is brought back by the lightweight heavy-duty drone for reuse. This invention uses a drone as a carrier, combined with the anti-adhesion isolation clamp and installation device, eliminating the need for contact with the conductors and high-altitude operations, resulting in high safety, fewer personnel, and low operating costs; it can eliminate the defects of adhesion and whipping of split sub-conductors in transmission lines, avoiding the resulting equipment damage and greatly improving the safety level of transmission line operation.
