The utility model discloses a high-temperature flue gas circulation ejector for a waste incineration system, which comprises a machine base, a driving mechanism, an ejector shell and a conical shrinkage pipe are arranged on the machine base, and a flue gas inlet and a flue gas outlet are arranged on the ejector shell; the conical shrinkage pipe is connected with the ejector shell, the large-caliber end of the conical shrinkage pipe is communicated with the flue gas outlet, and the small-caliber end of the conical shrinkage pipe is provided with a flue gas injection pipe; a rotatable driving main shaft is arranged in the ejector shell, the output end of the driving mechanism is connected with the driving main shaft, the driving mechanism can drive the driving main shaft to rotate, the driving main shaft is sleeved with spiral fan blades, and the spiral fan blades are used for blowing air towards the smoke outlet. According to the utility model, the residence time of flue gas in the furnace can be prolonged, so that harmful substances in the flue gas can be fully decomposed; flue gas is injected, turbulent mixing of the flue gas and oxygen in the combustion chamber is enhanced, and decomposition of harmful substances is accelerated; the whole structure is compact, and placing, carrying and maintaining are convenient.

The utility model relates to a kind of medical mechanical claw hand, including handle, the left side rotation of handle is equipped with clamping finger, the top of handle is equipped with transition connecting box, the top of transition connecting box is fixedly installed with bent pole, the inside of transition connecting box is provided with locking assembly, the side fixedly installed with extension rod of bent pole away from transition connecting box.This medical mechanical claw hand, by setting transmission work component, cooperate with finger shaft and winding wheel etc., only need to be by thumb and index finger to be inserted into the clamping finger on handle, control the opening and closing of clamping finger, it can be controlled by finger shaft etc. Structure to control clamping tooth plate work, by the above setting, not only the required mechanical structure is less, and operation is simple, reduce its upper hand threshold, reduce minimally invasive surgery training cost, improve surgical efficiency, with practicality, by setting locking assembly, realize the locking and relaxation of left and right swing and pitch angle during the operation of the device.

The utility model discloses a kind of car wiper of easy installation, it includes: quick-release wiper support rod and support rod connecting block, the quick-release wiper support rod lower end inner wall is fixedly connected with support rod connecting block, the support rod connecting block inside is hollowed out and is equipped with drainage facility, support rod connecting block middle lower end is fixedly connected with connecting bearing, the connecting bearing lower end is fixedly connected with car wiper, by: quick-release wiper support rod upper end setting press and anti-escape buckle device, portable quick removal and installation operation to support rod connecting block are realized, support rod connecting block is provided with elastic buckle device, integrated connection design saves the installation of component, help machine automation production, reduce manufacturing cost and maintenance cost, and support rod slide rail inside is made to reduce hollowing and internal drainage processing, reduce motor operation load, simultaneously avoid internal waterlogged rust problem.

The application provides a variable dihedral angle inflatable folding wing based on an electric response shape memory polymer and a control method, which comprises a wing shell, a control system and a pump; the wing shell comprises a framework, an elastic body electrothermal layer and a flexible skin, the framework comprises a wing rib and a spar, and the spar is provided with an electric response shape memory polymer; an upper air bag and a lower air bag which are not conductive to each other are symmetrically installed inside the wing contour between adjacent wing ribs; adjacent upper air bags are connected to each other, and adjacent lower air bags are connected to each other; the upper air bag and the lower air bag at one end of the wing contour are connected with the pump respectively; the control system controls the electric response shape memory polymer to conduct electricity, so that the spar generates thermal deformation; and the control system controls the pump to make the upper air bag or the lower air bag negative pressure, so as to change the upper or lower dihedral angle of the wing. The application can realize variable dihedral angle under different flight requirements.
