The invention relates to an epoxy-pouring full-insulation solid isolating switch, which comprises an isolation body, a grounded contact, an isolation contact, a middle contact, an isolation moving contact, a driving screw rod, a fixed nut and a driving gear part, wherein the grounded contact and the isolation contact are arranged at two ends of the isolation body respectively, the middle part of the isolation body is provided with the middle contact, the upper end of the isolation contact is connected with a bus contact through a bus-bar, the bus contact is arranged on the top of the isolation body, and the isolation moving contact is always contacted with the middle contact through a watch chain sensing finger. The isolation switch slides between two positions of the middle contact and the isolation contact or the middle contact and the grounded contact to form the conduction or the isolation grounding of the isolating switch. The entire isolating switch is poured into a fully-sealed integral structure with epoxy resin. The epoxy-pouring full-insulation solid isolating switch provided by the invention has the advantages of full insulation, insulation structure, small volume, extensibility, easy installation, free maintenance, long life, stable and reliable performance, and the like.

The invention relates to a method for improving quality of a doped DLC (diamond-like carbon) film. A shielding device is arranged around a workpiece before plasma CVD (chemical vapor deposition) of the doped DLC film on the workpiece, and an opening is formed in the shielding device and directly faces a plasma outlet; during plasma CVD of the doped DLC film, the shielding device does not rotate with the workpiece but is equipotential with the workpiece. According to the method provided by the embodiment, the shielding device is mainly arranged around the rotating workpiece during deposition, so that the position with extremely uneven plasma density distribution nearby the circumference of the workpiece is shielded, only deposition of high-density ions of plasma right facing the plasma outlet is received, the uniformity, binding force and the like of the finally obtained film are greatly improved, and the method is quite suitable for industrial mass production.

A gas wing airflow directional aircraft comprises a machine body and a control room and is characterized in that the control room is arranged at the front part of the machine body, a lifting duct is arranged in the middle of the machine body, a propeller is arranged in the lifting duct, a gas separation bin plate with a herringbone longitudinal section is arranged below the propeller in the lifting duct, a transmission shaft of the propeller penetrates through a central hole of the air separation bin plate and is connected with a power transmission system in the control room, gas spraying windows are symmetrically formed in side walls of left and right sides of the lifting duct, the bottom end of the air separation bin plate is connected with the gas separation bin plate, wing-shaped airfoils are symmetrically arranged at the parts, outside the gas spraying windows, at the side walls of left and right sides of the lifting duct; the sections of the airfoils are outwards bulged arc surfaces; rear half parts, close to the machine body, of a propelling duct are symmetrically arranged at two sides of the machine body, and the rear part is connected with a propelling spraying tube, and a fan is arranged in the propelling duct. The gas wing airflow directional aircraft can form directional airflows, the airflows flow to the inside of the airfoils, and are then sprayed out from the bottom ends of the airfoils to form counter-acting force to the machine body so as to fast support the machine body.

The invention discloses an active infrared camouflage structure based on vanadium dioxide, which comprises: a heating base, a vanadium dioxide film and an electrode pair; the vanadium dioxide film is coated or evaporated on the upper surface of the heating base; the heating base is vanadium dioxide While the film provides support, the temperature of the vanadium dioxide film is changed by current heating; the electrode pairs are located at both ends of the heating substrate, connected to the external power supply and the heating substrate, and used to change the temperature of the heating substrate, thereby adjusting the change of the vanadium dioxide emissivity. Infrared camouflage capable of low power consumption and fast adjustment.

A constant flow rate smoking machine, comprising a cigarette holder arranged on the upper panel, a total particulate matter trap connected to the mainstream smoke pipe at the rear end of the holder, a reversing valve, a gas flow detection and control device, It is composed of a vacuum pump and a mainstream smoke collection port. A plexiglass cover for collecting side flow smoke is installed on the upper panel, and a side flow smoke outlet is opened on the upper panel inside the glass cover, and a side flow smoke outlet is added to the outlet. The flue gas filter is in communication with the side flow flue gas fan and the side flow flue gas collection port; the total particulate matter trap is installed on the upper panel, and the reversing valve, gas flow detection control device, and vacuum pump are arranged on the bottom plate. The valve is provided with a purge gas path interface. The invention can stabilize the suction flow rate of cigarettes and realize the setting and control of constant flow rate; it can clean the smoke channel in time, which greatly reduces the influence on the experimental results; and it can expand the collection of mainstream smoke and side smoke when cigarettes are burning. Flow flue gas, realize the analysis and detection of main and side flow flue gas components.

The invention discloses a material level detecting method and a detection device based on vibration signal of ball mill rotary drum. The invention is characterized in that the method comprises the following procedures: (A) installing a vibration acceleration transducer on the ball mill rotary drum; (B) setting data collection parameters, and calculating a circumferential angle L when the transducer collects a group of data measuring points; (C) determining the circumferential area of the transducer for data collection, and acquiring the relation between the maximum impact point of a steel ball on the ball mill rotary drum and the level; (D) acquiring the impact vibration signal between the steel ball in the drum and the coal, steel ball and steel ball, as well as the steel ball and the drum wall; (E) determining the maximum impact point of the steel ball on the drum; (F) calculating the level value of the ball mill in the state. The detection device comprises a ball mill drum and a vibration accelerator arranged on the ball mill drum. The invention has the advantages of real-time and accurate level detection, and avoidance of influence on measurement results caused by changes of category of coal, water content of coal, particle size of coal and other factors.
