The invention belongs to the technical field of gas turbine power station units, and relates to a flue gas damper, in particular to a flue gas damper driving mechanism. The flue gas damper driving mechanism comprises a front support seat arranged at the front end of a three-way shell and a rear support seat arranged at the rear end of the three-way shell, the front support seat and the rear support seat are arranged coaxially, a front shaft is rotationally connected on the front support seat, a rear shaft is rotationally connected on the rear support seat, connection ends of the front shaft and the rear shaft both extend into the three-way shell, two ends of a torque tube are fixed on the rear shaft and the front shaft respectively, and reversing baffles are welded on the torque tube. The flue gas damper driving mechanism is simple and reasonable in structure, is technically improved focusing on the problems of flue gas damper driving devices in the prior art, and is effectively suitable for controlling opening and closing of the flue gas damper.

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.

The invention provides a transfer window for high-grade biological safety laboratory, which belongs to the technical field of transfer window for biological laboratory. The invention includes a bracket, the inner bottom side of the bracket is rotatably connected with pedals, the pedals are provided at two places, and the two pedals are respectively rotatably connected to the front and rear sides inside the bracket, and the inner bottom ends of the two brackets are also fixedly connected with PLC controller, two PLC controllers are located under the two pedals respectively, and buttons are installed on the top of the two PLC controllers. The drive of the motor C makes the fan tilt, and the dust on the fan is shaken off to the inner position of the transfer box for storage through the tilt of the fan, thereby achieving a more practical purpose, and solving the problem that the existing transfer windows are opened manually. potential pollution problems.
