The invention relates to the technical field of fire fighting, in particular to intelligent fire fighting equipment based on remote control of the Internet of Things, which comprises a mounting mechanism, two side plates arranged at an interval, a support, two side shafts, a mounting shaft and a camera, the two side plates are mounted on the mounting mechanism, and the end parts of the side shafts are rotatably mounted on the side plate on the same side; the mounting shaft is rotatably mounted on the support, and the camera is fixedly connected to the upper end of the mounting shaft; dense smoke particles adsorbed on the camera are cleaned through the cleaning mechanism, so that the camera can clearly shoot a clear picture of a fire scene, and firefighters can accurately know the condition of the fire scene through the camera.

The utility model relates to the technical field of surveying and mapping rulers, and provides an adjustable intelligent surveying and mapping ruler, which comprises a transverse ruler, a movable seat and a brake assembly, a clamping block is arranged at the bottom of the movable seat, the clamping block is connected to the inner wall of the transverse ruler in a sliding manner, and the brake assembly is arranged on the outer wall of the movable seat; an angle sensor is arranged on the outer wall of the movable seat, a fixed block is arranged at the detection end of the angle sensor, and a laser range finder is placed above the fixed block. Through the arrangement of the movable seat, the fixed block can stably move on the transverse ruler, in order to avoid position deviation of the laser range finder in the moving process, through the arrangement of the angle sensor, the rotation angle can be accurately known when the laser range finder is rotated, and then calculation is more convenient; the laser range finder can hover at any angle when rotating, and angle deviation of the laser range finder during measurement is avoided.

This utility model discloses an angle measuring device for oral surgical guides, relating to the field of medical measuring instruments. It includes a connecting base block, a vertical rod fixedly connected to the center of the upper surface of the connecting base block, and a positioning rod fixedly connected to the center of the bottom surface of the connecting base block. A reference plate is provided at the upper end of the vertical rod, and an indicator plate adapted to the reference plate is rotatably connected to the side wall of the vertical rod. By inserting the positioning rod into the implant hole, the positioning plate abuts against one side of the tooth, aligning the connecting base block. Then, the indicator plate is rotated so that the abutment plate abuts against the outer side of the adjacent tooth. At this time, the pointer at the upper end of the indicator plate also rotates with it and is positioned on the surface of the reference plate by a resistance strip. The device is then removed to observe the scale data from the front. By removing the device to observe the data, the angle data can be obtained more accurately, and the fixed indication after the pointer is removed further improves the accuracy of the data.
