Description

Technical Field

[0001] The invention relates to the technical field of pressure-bearing special equipment measurement, and in particular to a rapid measurement device for the diameter of a container barrel and a pipeline. Background Art

[0002] In industrial production, energy supply, water treatment and many other fields, containers and pipelines are core components for fluid transmission and storage. The stability and efficiency of their operating status are directly related to the safety performance of the entire production system. During use, changes in the diameter of the container barrel and pipeline (such as diameter reduction due to corrosion, wear, etc.) may affect the pressure bearing capacity and sealing performance of the system. Regularly measuring the diameter of the container barrel and pipeline can timely discover potential safety hazards and take corresponding repair or replacement measures to ensure the safe operation of the system. Diameter measurement plays an important role in ensuring flow demand, controlling pressure loss, optimizing material costs, evaluating safety performance, maintenance and replacement basis, design verification, compliance inspection, and improving system efficiency. At present, indirect measurement methods are usually used for on-site measurement of container barrels and pipelines. The diameter is calculated by the corresponding formula after a steel tape measure is wrapped around the container barrel and pipeline, or the diameter is calculated after a soft rope is wrapped around the circumference and the length is measured with a ruler. The above measurement method has a large error because the steel tape measure cannot completely fit the container barrel and pipeline, and although the soft rope can be completely fitted, there is a secondary measurement, which also has a large error. At the same time, since secondary calculation is required, the measurement efficiency is low. Summary of the invention

The device overcomes the defects of traditional measuring methods, realizes automatic real-time measurement of the diameter of a container barrel and a pipe, solves the problem of large measurement errors, and effectively improves the efficiency of the measuring operation.

[0005] Furthermore, the device also includes a winding mechanism, which is arranged on the rotating shaft so that the tape measure is wound tightly around the rotating shaft.

[0006] Furthermore, the angle sensor is a capacitive multifunctional precision macro angle measurement sensor, and the microprocessor is a single chip microcomputer. Since the rapid measuring device for the diameter of a container barrel and a pipe of the present invention adopts the above technical solution, that is, the device includes a tape measure, a shell with an opening, a rotating shaft, an angle sensor and a microprocessor with a display screen, the rotating shaft is arranged at the center of the shell, the angle sensor is arranged in the shell and connected to the rotating shaft, the angle sensor detection signal is transmitted to the microprocessor, and the tape measure is wound around the rotating shaft and the end thereof extends out of the opening of the shell.

BRIEF DESCRIPTION OF THE DRAWINGS

[0007] The present invention is further described in detail below in conjunction with the accompanying drawings and embodiments: Figure 1 The figure is a schematic diagram of a rapid measuring device for the diameter of a container cylinder and a pipeline according to the present invention. DETAILED DESCRIPTION

[0008] Implementation example Figure 1 As shown, the rapid measuring device for the diameter of a container barrel and a pipeline of the present invention comprises a tape measure 1, a shell 2 with an opening 21, a rotating shaft 3, an angle sensor 4 and a microprocessor 5 with a display screen 51, wherein the rotating shaft 3 is arranged at the center of the shell 2, the angle sensor 4 is arranged in the shell 2 and connected to the rotating shaft 3, the detection signal of the angle sensor 4 is transmitted to the microprocessor 5, and the tape measure 1 is wound around the rotating shaft 3 and the end thereof extends out of the opening 21 of the shell 2.

[0009] Preferably, the device further comprises a winding mechanism (not shown in the figure), which is arranged on the rotating shaft 3 so that the tape measure 1 is wound tightly on the rotating shaft 3. The winding mechanism allows the tape measure to fit the container body or the pipe body during the measurement process, thereby avoiding measurement errors caused by the steel tape measure not being able to fit completely.

[0010] Preferably, the angle sensor 4 is a capacitive multifunctional precision macro angle measurement sensor, and the microprocessor 5 is a single chip microcomputer. The model of the angle sensor is SGC7626C, and the model of the microprocessor is BST-V51 single chip microcomputer.

[0011] When measuring the diameter of a container barrel or a pipe, pull the tape measure out of the shell, wrap around the container barrel or pipe body for one circle, and then lock it. After the tape measure is pulled out, the angle sensor rotates with the shaft and measures the angle of rotation. If the shaft rotates α°, the value is first calculated, and then divided into the integer part N and the decimal part n. The length of the tape measure moving is, where D is the total diameter of the shaft and the tape measure wrapped around the shaft, and T is the thickness of the tape measure. After the above detection data and calculation formula are calculated by the microprocessor, the length of the tape measure moving is directly displayed on the display screen, so as to quickly obtain the measurement data of the container barrel or pipe diameter.

[0012] This device is used in regular inspection projects such as gas storage tanks and nitrogen pipelines in steel plants, solving the problem of large indirect measurement errors. With two people operating, this device can complete the measurement and calculation of the diameter of a cylinder or pipe within 30 seconds, increasing the efficiency by at least 3 times.

[0013] The device can be placed on the container cylinder or pipeline body in multiple directions, and then quickly measure the diameter of the cylinder and the tube at the same section, which can realize the automatic measurement of the cylinder and tube diameters, avoid the large error of the indirect measurement method, and improve the measurement accuracy and efficiency.
