The utility model has the following advantages and effects: through the arrangement of the rotary display device, the single adjustment and recording of year, month and date are realized by controlling the rotation of the roller after the maintenance is finished, so that the last maintenance time can be accurately known during the next maintenance, and the maintenance time is not afraid of forgetting and losing; therefore, the effect of conveniently recording the maintenance time is achieved.

The present invention provides a method for determining the safe thickness of a deep-buried, water-rich fault-broken zone tunnel against sudden changes and a test component thereof, including a test component, wherein the test component consists of a test box, a ground stress loading system, a water supply system, and a monitoring system. The test box is filled with ordinary surrounding rock and constructed with surrounding rock of a fault-broken zone, and high ground stress is loaded on the test box, and then tunnel excavation is performed. When the value calculated by the detection data is greater than the safety limit, tunnel excavation is stopped. At this time, the safe thickness of sudden changes recorded at the excavation distance of the tunnel face is the difference between the distance between the middle of the face and the fault plane before tunnel excavation and the distance of the tunnel face that has been excavated. Then, the specific value of the safety limit is obtained by weighted averaging the detection data, and the sudden change point can be intuitively obtained, thereby deducing the distance of the tunnel that has been excavated, and then directly obtaining the sudden change safety thickness, which is finally embodied in digital form, so that the sudden change safety thickness is directly quantified, and it is convenient to accurately know the sudden change safety thickness.

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 embodiment of the invention provides a fire scene information processing method based on intelligent wearable equipment and a related device, and the method comprises the steps: obtaining the first position information and fire behavior information of a target fire area; determining a target water source for fire extinguishing according to the first position information; the fire behavior information comprises fire behavior area, fire behavior height and combustible information; target working power needed by each water pump is determined; and sending the water pump number target working power to the monitoring management system. The server obtains the total length of water pipes required by fire extinguishing, the number of water pumps and the target working power of each water pump by obtaining and analyzing the first position information, the fire behavior information, the water pump information, the target water pipe information and the water source information of the target fire area, so that firefighters can timely and accurately know the equipment information required by fire extinguishing; and the fire scene information processing intelligence of the server can be improved.

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.
