Abstract

Technical Field
[0001] This utility model relates to the field of measuring equipment technology, and in particular to a pipe depth measuring device. Background Technology
[0002] In municipal engineering projects such as the repair, reconstruction, and expansion of urban drainage pipelines, the initial design phase requires a current status survey and assessment. This includes collecting design drawings, maintenance records, and operational reports of the existing drainage system, as well as conducting on-site surveys and explorations of existing storm and sewage pipelines to understand their actual condition, including pipeline layout, materials, damage, depth, location, diameter, and direction. This helps identify problems in the existing system, such as poor drainage, leakage, and structural damage. Only after completing these preliminary tasks can the detailed design phase begin, ensuring the smooth implementation and operation of the project.
[0003] In existing technologies for measuring pipeline depth, the complex conditions within the manhole, including obstructions, debris, siltation, and blockages, significantly complicate the measurement task and greatly increase costs and time. Therefore, this paper proposes a pipeline depth measurement device to address these issues. Utility Model Content
[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a pipe depth measuring device.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: a pipe depth measuring device, comprising two stainless steel square tubes, each of which has a scale mark on its surface, a U-shaped block is slidably connected to the surface of a single stainless steel square tube, a circular level is fixedly installed on one side of the outer surface of the U-shaped block, and an auxiliary mechanism is installed on the outer surface of the stainless steel square tube, and a crossbar is installed on one side of the other stainless steel square tube.
[0006] The auxiliary mechanism includes a positioning frame that is slidably connected to the outer surface of a stainless steel square tube. A first stud is threadedly connected to the side wall of the positioning frame. One end of the first stud abuts against the outer surface of the stainless steel square tube, and a first torsion block is fixedly connected to the other end of the first stud. Two lead screws are symmetrically fixedly connected to both sides of the outer surface of the positioning frame, and threaded sleeves are threadedly connected to the outer surfaces of the two lead screws.

[0008] Furthermore, a second stud is fixedly connected to one end of the crossbar, and one end of the second stud is threadedly connected to the inner cavity of a single threaded hole.
[0009] Furthermore, a metal spring is fixedly connected to one side of the U-shaped block, and one side of the metal spring abuts against the outer surface of the stainless steel square tube.
[0010] Furthermore, a third stud is threaded through the side wall of the U-shaped block, one end of the third stud abuts against the outer surface of the stainless steel square tube, and the other end of the third stud is fixedly connected to a second torsion block.

[0021] like Figure 1 - Figure 5 As shown, a pipe depth measuring device is disclosed, comprising two stainless steel square tubes 1, each with a scale mark 2 on its surface. A U-shaped block 4 is slidably connected to the surface of each stainless steel square tube 1. A circular level 5 is fixedly installed on one side of the outer surface of the U-shaped block 4. By observing the circular level 5, the staff can easily identify whether the stainless steel square tube 1 is vertically in a horizontal position. An auxiliary mechanism 6 is installed on the outer surface of the stainless steel square tube 1, and a crossbar 3 is installed on one side of the other stainless steel square tube 1.
[0022] Among them, such as Figure 5 As shown, the auxiliary mechanism 6 includes a positioning frame 601 that is slidably connected to the outer surface of the stainless steel square tube 1. A first stud 602 is threadedly connected to the side wall of the positioning frame 601. One end of the first stud 602 abuts against the outer surface of the stainless steel square tube 1, and the other end of the first stud 602 is fixedly connected to a first torsion block 603. Two lead screws 604 are symmetrically fixedly connected to both sides of the outer surface of the positioning frame 601. The outer surfaces of the two lead screws 604 are threadedly connected to threaded sleeves 605. One end of the threaded sleeve 605 is fixedly connected to an anti-slip block 606. The anti-slip block 606 is made of rubber. By setting the anti-slip block 606 made of rubber, the stability of the auxiliary mechanism 6 can be improved and the sliding of the auxiliary mechanism 6 when fixing the stainless steel square tube 1 can be avoided.
[0023] And such Figure 1 and Figure 2 As shown, the inner cavities of the two stainless steel square tubes 1 are provided with slots 7, and the tops of the two stainless steel square tubes 1 are fixedly connected with square connecting tubes 8 that match the slots 7. By setting the auxiliary mechanism 6, the stainless steel square tubes 1 can be positioned, improving the stability of the stainless steel square tubes 1 in use. When two or more stainless steel square tubes 1 are inserted and assembled at the same time, the measurement efficiency of the pipeline can be improved.
[0024] Correspondingly, threaded holes 9 are provided on both sides of the outer surface of the square connecting tube 8 and the stainless steel square tube 1. A second stud 10 is fixedly connected to one end of the crossbar 3. One end of the second stud 10 is threadedly connected to the inner cavity of the single threaded hole 9. The slot 7, the square connecting tube 8 and the threaded hole 9 cooperate to facilitate the connection and fixation of the stainless steel square tube 1 by the staff, increase the length of the main rod and improve the measurement efficiency.
[0025] Furthermore, by setting a second stud 10 and threaded hole 9 to cooperate, it is convenient for staff to replace crossbars 3 of different lengths, thereby improving the stability of the measuring device.
[0026] like Figure 4 As shown, a metal spring 11 is fixedly connected to one side of the U-shaped block 4. One side of the metal spring 11 abuts against the outer surface of the stainless steel square tube 1. By setting the metal spring 11, the U-shaped block 4 can be pre-fixed, which makes it convenient for the staff to vertically move the U-shaped block 4 to adjust the position of the circular level 5. A third stud 12 is threaded through the side wall of the U-shaped block 4. One end of the third stud 12 abuts against the outer surface of the stainless steel square tube 1, and the other end of the third stud 12 is fixedly connected to a second torsion block 13. By using the cooperation of the third stud 12 and the second torsion block 13, the U-shaped block 4 can be fixed, thereby improving the stability of the U-shaped block 4 in use.
[0027] The scale mark 2 is formed by laser engraving, and the scale mark 2 is engraved on both sides of the stainless steel square tube 1. The scale mark 2 set by laser engraving not only has a long service life, but also has a good display effect.
[0028] In use: First, the staff fixes the square connecting tube 8 to one side of one of the stainless steel square tubes 1, then inserts the bottom of the other stainless steel square tube 1 into the top of one of the stainless steel square tubes 1, and fixes the two together with external bolts.
[0029] After fixing, the positioning frame 601 and the U-shaped block 4 are installed on the surface of the stainless steel square tube 1. Then, the stainless steel square tube 1 is inserted into the inner cavity of the pipe. When the stainless steel square tube 1 moves the crossbar 3 downward and touches the bottom, the operator rotates the two threaded sleeves 605. The threaded sleeves 605 rotate on the surface of the screw 604 and move outward. When the threaded sleeves 605 move, they drive the anti-slip block 606 to contact the inner wall of the pipe, which can position the stainless steel square tube 1, thereby improving the stability of the stainless steel square tube 1. In addition, by observing the circular level 5 on one side of the U-shaped block 4, the operator can easily check whether the stainless steel square tube 1 is in a vertical and horizontal position. When the stainless steel square tube 1 is in a horizontal position, the depth of the pipe can be determined by observing the scale mark 2.
[0030] The aforementioned auxiliary mechanism can position the stainless steel square tube 1, improving its stability. Simultaneously, by connecting two or more stainless steel square tubes 1, the measurement efficiency of the pipeline can be improved. Furthermore, by using the observation circular level 5, it is convenient for staff to identify whether the stainless steel square tube 1 is vertically aligned with a horizontal position. This solves the problem that current pipeline measurements are hampered by the complex conditions inside the manhole, including obstructions, debris, siltation, and blockages, which greatly increase measurement costs and time.

Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
