In the construction process, a cross joint measurement module passes through a pipe joint, a convex flange one end is connected with a concave flange at the tail of the shield machine, the concave flange one end is connected with a convex flange at the bottom of the one-dimensional workbench, two circular grating angle sensors and a circular grating reading head are arranged on the cross joint, the rotation angle measurement of two mutually perpendicular axes of the cross joint is realized, a Bluetooth wireless transmission module reads the rotation angles of each joint at the same time, and the rotation angles are transmitted to a computer, the computer collects each data every moment, the position coordinates of the top end of the shield machine relative to a reference coordinate system are obtained through calculation, and the pose of the shield machine is detected in real time.

This utility model discloses a multifunctional measuring and recording ruler for wound undermining and sinus tracts. It includes a right-angle measuring ruler with connecting measuring rulers fixed at both ends, and a movable measuring ruler at the end of the connecting measuring ruler furthest from the right-angle measuring ruler. It also includes a movable sleeve connected to the top of the right-angle measuring ruler, with a colored pen inside the sleeve. This multifunctional measuring and recording ruler for wound undermining and sinus tracts allows for precise measurement of wound undermining and sinus tracts within the patient's wound using the right-angle measuring ruler, movable measuring ruler, and connecting measuring ruler. When wound depth needs to be measured, the ruler is held vertically, and one end of the movable measuring ruler is inserted into the wound to measure the depth. The depth is then marked with a colored pen according to the different depths of the wound, allowing for accurate and convenient recording of wound undermining and sinus tract size and depth, providing a basis for scientific wound assessment and treatment adjustments.

This invention provides a method and apparatus for measuring the intensity distribution of high-energy laser light, relating to the field of laser intensity measurement technology. The apparatus includes: a beam sampling element, a sampling material, a sampling material control platform, a damage spot monitoring system, and a data processing terminal. The beam sampling element is used to sample a single beam of fixed diameter from the high-energy laser to be measured, obtaining the incident laser. The sampling material control platform, connected to the sampling material, is used to adjust the incident angle of the incident laser onto the surface of the sampling material and to adjust the position of the incident laser acting on the surface of the sampling material. The damage spot monitoring system is used to monitor the radius of the laser damage spot on the surface of the sampling material. The data processing terminal determines the intensity distribution of the high-energy laser to be measured based on the prior data of the damage threshold of the sampling material and the radius of the laser damage spot. This invention achieves direct measurement of the intensity and intensity distribution of high-energy laser light without using a beam attenuation element, providing intuitive results and simple operation.

This utility model relates to a multi-range flow measurement device, including a main cavity, a rotating shaft, a damping adjustment module, a sealing assembly, a swing rod assembly, a swing arm assembly, a baffle, a base, and an angle sensor. The rotating shaft is disposed within and extends through the main cavity. One end of the rotating shaft is connected to the damping adjustment module, and the other end is connected to the angle sensor. One end of the swing rod assembly is sleeved on the rotating shaft and securely connected, while the other end of the swing rod assembly is connected to the swing arm assembly, which has a baffle. The main cavity is installed at the flow measurement position via the base. During measurement, the baffle is in direct contact with the fluid. One end of the sealing assembly is connected to the main cavity, and the other end is connected to the swing rod assembly or the swing arm assembly, isolating and sealing the baffle and the fluid outside the main cavity. This utility model enables flexible adjustment and wide-range measurement. The damping adjustment module can adjust the damping force according to actual working conditions, avoiding the measurement inaccuracy caused by the baffle reaching its maximum range at high flow rates.
