A base serves as the fulcrum of a balancing plate, a rotor wing of the rotor wing system is mounted reversely, so that the lifting force direction goes downwards vertically, a torque sensor is used for measuring a torque generated in the rotating process of the rotor wing of the rotor wing system, a weight is placed in a weight disk soas to balance the weights of the two ends of the balancing plate, thus the balancing plate can be in a balanced state, and a force cell is used for measuring the lifting force generated in the rotating process of the rotor wing of the rotor wing system. The lever type hovering characteristic test simulating device is used for testing the hovering characteristic of the Mars unmanned aerial vehiclerotor wing system.

Special sealing tank for heating and filtering type gastric lavage machine for medical operation
The invention provides a special sealing tank for a heating and filtering type gastric lavage machine for medical operation, wherein the sealing tank comprises an upper cavity and a lower cavity. Thebottom of the upper cavity and the top of the lower cavity are provided with circular openings respectively. A connecting catheter and a cylindrical regulating block are arranged on an upper sealing cover, and an L-shaped catheter is arranged in the inner part of the cylindrical regulating block. A rotating handle is arranged at the top of the cylindrical regulating block, and the cylindrical regulating block can be rotated by rotating the rotating handle. When the L-shaped catheter in the cylindrical regulating block is connected with the connecting catheter, the connecting catheter can be connected with the upper chamber. When not in use, the rotating handle can be rotated to make the liquid outlet end of the connecting conduit connected with the outer wall of the cylindrical regulatingblock, so as to play a sealing role.

Electric cooking device
ActiveCN107752717AChange the pressureEvenly heatedCooking-vessel lids/coversVessels with intergral heatingElectricityEngineering
The invention discloses an electric cooking device. The electric cooking device comprises a pot body in which a cooking cavity is formed, a pot cover which is arranged on the pot body for opening or closing the cooking cavity and in which a plurality of pressure relief openings with different areas are formed, a plugging structure which is arranged on the pot cover, a plurality of sealing deviceswhich are used for sealing the corresponding pressure relief openings, and a driving device which is used for driving the plugging structure to move above any one of the pressure relief openings to seal the pressure relief opening, wherein the sealing device of the pressure relief opening sealed by the sealing structure is in the open position and the rest sealing devices are in the sealing position of sealing the corresponding pressure relief openings. In this way, the electric cooking device can change the pressure in the cooking cavity, so that the food can be tumbled under the pressure difference and heated more uniformly.
