The utility model discloses a quick disconnecting type disconnecting device for a rigid contact network. The quick disconnecting type disconnecting device comprises a first fixed busbar, a second fixed busbar and a movable busbar, an electric connection device is arranged between the first fixed busbar and the movable busbar, and an electric connection device is arranged between the movable busbar and the second fixed busbar; the first fixed busbar is hinged with the movable busbar; the movable busbar is provided with a movable busbar second wire clamp, the movable busbar second wire clamp is provided with a lower connecting part, the upper portion of the lower connecting part is in threaded connection with an upper connecting part, the upper connecting part is rotatably connected with the busbar suspension supporting structure, and the upper connecting part is connected with a driving motor. The rotating axis of the upper connecting part coincides with the axes of the threads of the upper connecting part and the lower connecting part. According to the scheme, the motor is adopted to drive the threads to be screwed in and screwed out, the structure stability under normal conditions can be guaranteed, rapid triggering under emergency conditions can be guaranteed, and the recovery process is easy to operate.

The present application belongs to the technical field of shaft flow pump seal flushing, and particularly relates to a machine seal flushing self-adaptive compensation system for a polyethylene shaft flow pump. The present application comprises a pump body with a pump cavity, and a front end bearing arranged in the pump body. The present application is characterized in that it comprises a compensation type piston cylinder with an axis arranged vertically, and a return cavity of the compensation type piston cylinder is located above a feed cavity. An oil inlet compensation pipeline is connected to the return cavity at one end and to a front end flushing pipeline where a high speed pump is located at the other end. A balance pipeline is connected to the feed cavity at one end and to a lubricating cavity where the front end bearing is located at the other end. The present application realizes an instant online compensation function of flushing liquid after interruption of flushing, thereby ensuring continuous lubrication and cooling effect of the bearing in the pump cavity and ensuring safety and continuity of high density polyethylene production.

This application belongs to the field of precast bamboo pile structures and discloses a sleeve-type precast bamboo pile structure, including a central bamboo pile and branch bamboo piles. The central bamboo pile is vertically inserted into the soil to bear vertical loads; the branch bamboo piles are inserted into the soil at a predetermined angle, with the lower end embedded and connected to the central bamboo pile, and the upper end extending outward in a direction away from the central axis of the central bamboo pile, thus forming a spatial force-bearing system. The inclined branch bamboo piles are equivalent to setting rigid barbs on the central bamboo pile in terms of mechanical transmission, and work together to create an "inverted cone soil locking" effect. When the pile is subjected to an upward pull force, the pressure exerted by each branch bamboo pile on the soil above and around it forces the pile foundation area to form an inverted cone-shaped soil plug or soil compression zone. Based on this mechanical mechanism, to pull out the pile, the self-weight and cohesion of the inverted cone-shaped soil must first be overcome, thereby significantly consuming the pull-out force and greatly improving the pull-out bearing capacity of the pile foundation.
