The invention discloses a siphon treatment pipeline sludge clearing system. The system comprises a water storage tank, a sludge pipeline, a clearing device, a horizontal shifting device and a locking device, a siphon pipe is arranged in the water storage tank in a sleeved mode, a siphon opening is formed in one side of the siphon pipe, an external hose is arranged in the sludge pipeline in a sleeved mode, one end of the external hose is fixedly connected with a water outlet pipe, one end of the water outlet pipe is fixedly provided with a transfer box, the clearing device is arranged in the sludge pipeline, the horizontal shifting device is arranged in the siphon pipe, the output end of the horizontal shifting device is connected with a sealing plate, the position of the sealing plate is controlled through the horizontal shifting device, and the locking device is arranged on one side of the water storage tank. The system has the beneficial effects that by means of the arrangement of the siphon pipe, water flow in the water storage tank is pumped out through the siphon effect of the siphon pipe, use of a water pump is reduced, and meanwhile the water flow can enter the external hose through the siphon pipe at a constant speed.

The invention discloses a dustbin room capable of intelligently classifying and stacking, and particularly relates to the technical field of dustbin rooms, the dustbin room comprises a protection frame, the inner wall of the protection frame is fixedly connected with a protection motor, and the output end of the protection motor is provided with a working screw rod; the outer wall of the working screw is in threaded connection with a threaded sliding block slidably connected with the inner wall of the protection frame, the outer wall of the threaded sliding block is rotationally connected with a supporting rod, the end, away from the threaded sliding block, of the supporting rod is rotationally connected with a telescopic block, and the outer wall of the telescopic block is fixedly connected with a telescopic plate slidably connected with the inner wall of the protection frame. By arranging the telescopic hole plate, compared with the prior art, in the protection frame, the telescopic block moves to drive the telescopic plate to slide along the inner wall of the protection frame to drive the telescopic hole plate to move, so that the telescopic hole plate moves to drive the turnover plate to rotate through the linkage sliding groove, and the turnover plate rotates through synchronous movement of the telescopic plate and the turnover plate; opening and closing operation of the protective door of the protective frame is achieved, and the influence of household garbage on the environment is reduced.

An isolating and grounding switch mechanism (1) and a gas-insulated metal-enclosed switchgear. The isolating and grounding switch mechanism (1) comprises a housing (19), an isolating switch (12), and a grounding switch (11). The isolating switch (12) comprises an isolating switch moving contact (124) and an isolating switch stationary contact (123) that are provided in parallel along an axial direction. The grounding switch (11) comprises a grounding switch moving contact (112) and a grounding switch stationary contact (113). The interior of the housing (19) is provided with a transformer connection terminal (145), an external connection terminal for connection to a main loop access conductive structure, and a guide contact base (14) and a connection contact base (15) horizontally provided in parallel along the axial direction. The transformer connection terminal (145) is provided on the guide contact base (14). The isolating switch stationary contact (123) is provided at a position of the connection contact base (15) facing the guide contact base (14). The external connection terminal is provided at a position of the connection contact base (15) that allows access of the main loop access conductive structure along the axial direction. The isolating switch moving contact (124) is axially guided to pass through the guide contact base (14), and has a switching-on station that is in contact fit with the connection contact base (15).
