The utility model discloses an inorganic composite insulation board with anti -drop protection relates to the technical field of insulation board, including wall and insulation board main part, the wall's outside coincides and is connected with insulation board main part, the inner surface of wall is provided with a plurality of positioning protruding. This inorganic composite insulation board with anti -drop protection through the hemispherical positioning protruding of wall inner surface and outer surface positioning groove eight groups corresponding coincides, realizes accurate positioning, prevents the deviation of insulation board main part when installing, the T type connecting groove of matrix distribution of insulation board main part outer surface and T type connecting column inlay, cooperate and connect the mechanical locking force that the end tapered expansion head of column inlay into wall connecting hole produces, and the fastening of second internal thread hole of installing plate through screw and wall, form multidirectional, multi -point stress connection system, the connection stability of insulation board main part and wall is strengthened significantly, effectively prevent the problem of falling due to external force, temperature change or long -term use, improve the building security.

The application discloses a kind of three-dimensional shape reconstruction methods of magnetic continuum interventional instrument, belong to magnetic interventional medical instrument technical field, comprising the following steps: S1, the magnetic field of magnetic interventional instrument is detected by external sensor;S2, the corresponding relationship model of guide wire magnetic segment magnetic field and its shape is established;S3, fusion intraoperative image and magnetic field information are three-dimensional shape reconstruction.The three-dimensional shape reconstruction method of magnetic continuum interventional instrument described above is used, without additional sensor on interventional instrument, also without changing the mechanical properties of interventional instrument, the shape and position of interventional instrument in patient body can be obtained, and have higher precision.

This utility model relates to the technical field of underground communication and electrical explosion-proof equipment in coal mines, and particularly to a flameproof and intrinsically safe gateway for coal mines. It includes a housing assembly, a flameproof battery chamber, an intrinsically safe chamber, a battery module, a data exchange unit, a power supply unit, a battery information display unit, an intrinsically safe component, an observation window assembly, a light panel assembly, an explosion-proof cable entry device, and an explosion-proof cable connector. The housing is made of metal, and an internal partition divides it into the flameproof battery chamber and the intrinsically safe chamber. The flameproof battery chamber houses the battery module and a rotary switch that provide independent power to the equipment. The data exchange unit collects and converts multiple RS485 signals, and the power supply unit provides intrinsically safe power and monitors the status in real time. The intrinsically safe component in the intrinsically safe chamber converts the signals into standard Ethernet and optical signals for output to the ground system. The battery information display unit displays the equipment's operating status in real time through the observation window, and the light panel assembly provides auxiliary lighting. This gateway possesses excellent flameproof and intrinsically safe performance.
