Description

Technical Field

[0001] This utility model relates to the field of water conservancy engineering technology, and in particular to a distance measuring device for water conservancy engineering supervision. Background Technology

[0002] In water conservancy projects, a large number of water transmission pipelines, drainage ditches, steel or PVC conveying pipelines, and nested water-passing components with multiple interconnected sections are used. During the construction phase, the project supervisor must check parameters such as pipe size, pre-embedded length, interface depth, inner diameter spacing, and installation location multiple times to ensure that the pipeline installation meets the design and hydraulic requirements.

[0003] In current pipeline supervision practices, the primary method for measuring pipeline length is by measuring the external length along the outer wall with a measuring tape. However, for common types of pipes in water conservancy projects, such as interlocking, nested, or irregularly shaped pipes, external surface measurements are affected by protrusions, interface differences, and variations in pipe wall curvature, leading to significant length errors. When accurate measurement of the internal effective length or interface depth is required, it is difficult to accurately reflect the actual effective length of the pipeline. Inserting a measuring tape, probe, or flexible ruler into the pipe for depth reading is inconvenient, resulting in frequent measurement deviations. Furthermore, it is difficult to ensure that the measurement direction is perfectly aligned with the pipe axis, thus affecting measurement accuracy. Utility Model Content

[0004] The technical problem this invention aims to solve is that existing methods for measuring distances within monitoring pipes are affected by the complexity of the pipe structure, resulting in large external measurement errors and difficulty in stable internal positioning, leading to low measurement efficiency and poor accuracy.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: a distance measuring device for water conservancy engineering supervision, including a connecting arm, the connecting arm being configured as an arc-shaped plate structure, and a push rod motor being fixedly installed on one side of the connecting arm. The output end of the push rod motor is detachably provided with a limiting plate for limiting one end of the measuring tape. Side plates are also fixedly connected to both sides of the connecting arm. A winding frame for fixing the measuring tape is fixedly installed at the top of the side plate, and a winding roller is rotatably installed at the top of the winding frame via a rotating shaft. Multiple guide roller frames are provided on the other side of the winding frame, and the multiple guide roller frames are evenly spaced and fixedly installed at the top of the connecting arm. An abutment plate is also fixedly connected to the bottom of the connecting arm, and the abutment plate is located below the side plate.

[0006] As a further improvement of this utility model, the limiting disk is configured as a disc-shaped structure, and a magnetic block one is fixedly connected to the top of the limiting disk, and a magnetic block two is also magnetically attracted to one side of the magnetic block one.

[0007] As a further improvement of this utility model, the center of the limiting plate is provided with a threaded hole, and the end of the push rod motor output rod is fixedly connected with a threaded column, and the outer periphery of the threaded column is provided with a thread that matches the threaded hole.

[0008] As a further improvement of this utility model, the guide roller frame includes a pair of support rods fixed to the top side of the connecting arm. The inner side of the support rods is rotatably connected to the guide cylinder through two rotating shafts, and a gap is reserved between the two guide cylinders for the tape measure to pass through.

[0009] As a further improvement of this utility model, a grip is fixedly provided at one end of the connecting arm, and a rectangular grip slot is provided through the center of the grip.

[0010] As a further improvement of this utility model, a rubber mounting strip is fixedly provided at the bottom of the connecting arm.

[0011] The beneficial effects of this utility model are as follows: The winding and guiding structure arranged at the top of this device forms a continuous guiding path, which forces the tape measure to be corrected in direction before entering the pipe and keeps it straight throughout the entire process of advancement, thereby effectively solving the problems of the tape measure being soft, easy to bend, and difficult to ensure the center line is consistent when measuring distances inside the pipe.

[0012] The electric telescopic mechanism at the limiting end uses stable axial thrust to allow the measuring tape to penetrate the pipe in a constant direction, avoiding the poor repeatability of distance measurements caused by uneven force and angle changes during manual pushing. Simultaneously, the magnetic limiting structure further ensures a constant and reliable reference position for the measuring tape end, preventing slippage or rotation during insertion, thus ensuring consistent and verifiable depth readings. Because the positioning area is below and the reading area is above, the operator can directly read the scale value from the top of the device during measurement, without needing to bend or adjust posture to find the scale position, making the reading process quick and less prone to errors.

It should be understood that the embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0021] This utility model provides a distance measuring device for water conservancy project supervision, including a connecting arm 1;

[0022] As attached Figure 1 , 2 As shown in Figures 3 and 4, the connecting arm 1 is configured as an arc-shaped plate structure. A handle 3 is fixedly installed at one end of the connecting arm 1, and a rectangular gripping slot is opened through the center of the handle 3 for easy gripping during operation. A push rod motor 2 is fixedly installed on one side of the connecting arm 1. A limiting plate 4 for limiting one end of the measuring tape is detachably installed at the output end of the push rod motor 2. The measuring tape is preferably made of thickened knitted fabric. Side plates 5 are also fixedly connected to both sides of the connecting arm 1. A winding frame 6 for fixing the measuring tape is fixedly installed at the top of the side plate 5. A winding roller 7 is rotatably installed on the top of the winding frame 6 via a rotating shaft.

[0023] As attached Figure 1 , 2As shown in Figures 3 and 4, multiple guide roller frames 8 are provided on the other side of the winding frame 6. These guide roller frames 8 are evenly spaced and fixedly installed on the top of the connecting arm 1. Each guide roller frame 8 includes a pair of support rods 81 fixed to the top side of the connecting arm 1. Guide cylinders 82 are rotatably connected to the inner side of the support rods 81 via two rotating shafts, and a gap is reserved between the two guide cylinders 82 for the tape measure to pass through, ensuring the tape measure can pass through. An abutment plate 9 is also fixedly connected to the bottom of the connecting arm 1, located below the side plate 5. The abutment plate 9 allows the device to be abutted against the edge of the tube being measured. Since the abutment plate 9 is located below the side plate 5, and the winding frame 6 and guide roller frames 8 are located above it, the abutment allows the operator to directly observe the tape measure scale from above. Furthermore, a rubber mounting strip 14 is fixedly installed at the bottom of the connecting arm 1 to prevent scratching the inner wall of the tube during the abutment operation.

[0024] As attached Figure 1 , 2 As shown in Figures 3 and 4, the limiting plate 4 is configured as a disc-shaped structure, and a magnetic block 10 is fixedly connected to the top of the limiting plate 4. A magnetic block 21 is also magnetically attracted to one side of the magnetic block 10. The magnetic blocks 10 and 21 reliably limit one end of the measuring tape. A threaded hole 12 is opened in the center of the limiting plate 4, and a threaded post 13 is fixedly connected to the end of the output rod of the push rod motor 2. The threaded post 13 has threads on its outer periphery that match the threaded hole 12. The limiting plate 4 and the output end of the push rod motor 2 are designed as a combination, which facilitates modular adaptation according to different measuring tape widths.

[0025] Working Principle: In practical implementation, the operator gently presses the bottom abutment plate 9 against one side of the pipe end, and the flexible contact of the mounting strip 14 avoids scratching the pipe wall. After the operator starts the push rod motor 2, the push rod motor 2 drives the end limiting plate 4 to push outward in a straight line, allowing the tape measure to be stably advanced along the pipe axis. The magnetic block 10 and magnetic block 2 11 on the top of the limiting plate 4 attract each other and clamp the end of the tape measure, so that the tape measure maintains a stable force boundary during the extension and retraction process. As the push rod motor 2 pushes forward, the measuring tape is guided step by step through the gaps between the multiple guide cylinders 82 of the guide roller frame 8, ensuring that the measuring tape always enters the pipe in a direction consistent with the pipe axis. After extending to one end of the pipe, the operator can directly observe the scale of the measuring tape from above the side plate 5, achieving real-time and accurate reading of the pipe depth or effective length. After the measurement is completed, the push rod motor 2 drives the limit plate 4 to retract in the opposite direction, and the measuring tape is automatically retracted with the cooperation of the winding roller 7 and the winding frame 6, so that the entire distance measurement process can be completed stably and continuously.
