Specific embodiments

[0024] In order to make the purpose, features and advantages of the utility model more obvious and easy to understand, the technical scheme in the utility model embodiment will be described clearly and completely in the following with reference to the drawings in the utility model embodiment. Obviously, the following described embodiments are only a part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor belong to the scope of protection of the utility model.

[0025] It should be noted that in the description of the utility model, the terms "upper", "lower", "left", "right", "inner", "outer" and other terms indicating direction or positional relationship are based on the direction or positional relationship shown in the drawings, which is only for the convenience of description, and does not indicate or imply that the device or element must have a specific orientation, be constructed and operated in a specific orientation, therefore it cannot be understood as a limitation of the utility model.

[0026] In addition, it should be noted that in the description of the utility model, unless otherwise specified and limited, the terms "installation", "connection", "connection" should be understood broadly, for example, it can be fixed connection, or detachable connection, or integrally connected; it can be mechanical connection, or electrical connection; it can be directly connected, or indirectly connected through intermediate medium, or the communication between two elements. For those skilled in the art, the specific meaning of the above terms in the utility model can be understood according to the specific circumstances.

[0027] For example, Figures 1 to 4As shown, the embodiment proposes an underground pipeline diameter measuring device, which comprises a handheld rod 1, which can be a straight rod, a bent rod or a foldable multi-section rod, for lowering the component for measuring the diameter to a certain depth; further comprises a main telescopic rod 2, which is hinged with the handheld rod 1, and is rotated to be perpendicular to the handheld rod 1 through the hinge point, so as to be conveniently inserted into the transverse pipeline to be measured; further comprises a measuring telescopic rod 3, which is hinged on the upper and lower sides of the main telescopic rod 2 respectively, and can be adjusted to be in a vertical state through the hinge point, and the end of the measuring telescopic rod 3 is installed with a touch point 14, which can adopt a mechanical touch switch, a pressure sensor or a touch sensor, and is used for sensing the inner wall of the pipeline to be measured, when the two touch points 14 touch the inner wall of the pipeline, the distance between the two touch points 14 is the diameter of the pipeline to be measured; further, a displacement sensor 4 is connected between the main telescopic rod 2 and the end of the measuring telescopic rod 3, in the embodiment, the displacement sensor 4 can be selected according to the application environment and the cost, such as a mechanical sensor, a laser ranging sensor and an ultrasonic ranging sensor, and the length of the measuring telescopic rod 3 can be obtained; wherein, the main telescopic rod 2, the measuring telescopic rod 3, the touch point 14 and the displacement sensor 4 are electrically connected with the intelligent device through a communication module, the communication module is used for realizing the bidirectional data interaction between the main telescopic rod, the measuring telescopic rod, the touch point 14 and the displacement sensor and the intelligent device, including the transmission of the measurement data and the issuing of the control instruction, the two telescopic rods are controlled to be extended through the intelligent device, the touch point 14 is ensured to touch the inner wall of the pipeline to be measured, when the touch point 14 touches the inner wall of the pipeline, the measuring telescopic rod 3 stops continuing to extend, the displacement sensor 4 transmits the lengthening distance of the measuring telescopic rod 3 to the intelligent device, and the distance between the two touch points 14 is the diameter through calculation.

[0028] In the actual measuring process, it is found that the bottom of the pipeline to be measured often accumulates various sundries, such as Figure 2As shown in the prior art, these sundries can seriously affect the accuracy of the measurement. For example, the underground pipeline diameter measuring device with patent application number 202320773533.8, the crossbar may be pressed on sundries during measurement, resulting in errors in the measurement of the pipe diameter; and the urban underground pipeline diameter measuring device with patent application number 202322897291.6, which uses laser ranging, may also produce errors due to the reflection of sundries, resulting in inaccurate measurement results. In order to solve this problem, in the present scheme, two measuring telescopic rods 3 are used for detection, which can adapt to various complex environments of the pipeline. The length of the measuring telescopic rod 3 can be adjusted according to the size of the pipeline to ensure that it can accurately contact the inner wall of the pipeline. Unlike the traditional crossbar side face method, the present scheme uses point contact to detect the inner wall of the pipeline, which can effectively avoid the interference of sundries. During measurement, the measuring telescopic rod 3 can also push away the sundries, so that the touch point 14 directly contacts the inner wall of the pipeline, and cooperates with the displacement sensor 4, so as to obtain more accurate pipe diameter data, real-time feedback of the measurement data, and transmission of the data to the intelligent device through the communication module transmission technology, facilitating subsequent data analysis and processing by the staff.

[0029] In some embodiments, the telescopic rod end is fixedly connected with an extension seat 5, recesses 6 are formed on the upper and lower sides of the end of the extension seat 5, a base 7 is hinged in the recesses 6, and the measuring telescopic rod 3 and the displacement sensor 4 described above are fixedly connected to the base 7. In this design, the measuring telescopic rod 3 and the displacement sensor 4 are adjusted to be stored or in working condition according to the needs by the hinged way, so that they can save space when idle.

[0030] In some embodiments, a storage groove 8 is formed at the bottom of the telescopic rod, and the main telescopic rod 2 and the measuring telescopic rod 3 and the displacement sensor 4 connected thereto can be rotated to the storage groove 8 through the hinge point, so that the whole forms a structure as shown in Figure 3 for easy carrying, transferring and placing.

[0031] Further, considering that some components are exposed, they may be damaged or affect the accuracy of the measurement during carrying and transferring. A magnetic recess 9 is formed on the top surface of the storage groove 8, and a protective shell 10 in a "U" shape is also included, and a magnetic plug 11 is fixedly connected to the top of the protective shell 10. The magnetic plug 11 can be inserted into the magnetic recess 9, so that the protective shell 10 is covered outside the storage groove 8, thereby achieving the purpose of protecting the internal components.

[0032] In some embodiments, a scale line 12 is arranged on one of the outer sides of the handheld rod 1. This design not only improves the versatility of the device, but also brings more convenience to the user. The arrangement of the scale line 12 enables the handheld rod 1 to be used as a ruler when not measuring the diameter of a horizontal pipeline. For example, when the height of a vertical pipeline needs to be measured, the user can directly use the scale line 12 on the handheld rod 1 to measure, saving the trouble of carrying additional measuring tools.

[0033] Further, a plurality of anti-slip convex sleeves 13 are fixedly arranged on the outer side of the handheld rod 1. The anti-slip convex sleeves 13 are made of anti-slip materials such as rubber, which can effectively enhance the stability of holding and prevent the handheld rod 1 from slipping during measurement.

[0034] In some embodiments, the handheld rod 1 and the main telescopic rod 2, as well as the groove 6 and the base 7, are connected by friction hinges. The main telescopic rod 2 or the measuring telescopic rod 3 can be controlled to rotate or lock within a range of 0°~90°. When in use, it can be manually rotated to 90°, so that the two measuring telescopic rods 3 are in a vertical state in the pipeline to be measured, so as to obtain more accurate measurement data.

[0035] Further, a gyroscope can be installed in the handheld rod 1 to control the handheld rod 1 to remain in a vertical state, so as to obtain more accurate measurement data.

[0036] The use of the tool is as follows:

[0037] S1: manually rotate the main telescopic rod 2 to 90°, perpendicular to the handheld rod 1, and then rotate the two telescopic rods perpendicular to the main telescopic rod 2;

[0038] S2: calibrate the initial distance between the two touch points 14, denoted as P;

[0039] S3: the worker lowers the handheld rod 1 to the bottom of the vertical pipeline, and then activates the main telescopic rod 2 to extend into the horizontal pipeline to be measured;

[0040] S4: activate the upper and lower measuring telescopic rods 3 to extend upward and downward, respectively, until the touch points 14 touch the top and bottom of the pipeline;

[0041] S5: measure the lengths of the two telescopic rods, denoted as L1 and L2, by the displacement sensor 4, and the distance between the two touch points 14 is the diameter of the pipeline;

[0042] S6: the inner diameter D of the pipeline to be measured is L1+L2+P.

[0043] The above describes the specific embodiments of the application in combination with the drawings, but is not a limitation on the protection scope of the application. Various modifications or variations made by those skilled in the art on the basis of the technical solutions of the application without creative labor are still within the protection scope of the application.
