Abstract
Description
Technical Field
[0001] This utility model relates to the field of measuring benchmark technology, and in particular to a measuring benchmark for quality inspection of water conservancy projects. Background Technology
[0002] Quality inspection of water conservancy projects is a key link in ensuring the safe and stable operation of water conservancy projects. Its work scenarios are widely distributed in various water conservancy facility construction sites, such as reservoir dams, river embankments, and irrigation canals. These site environments are complex and varied, and may be located in remote mountainous areas or places with inconvenient transportation, or in areas with narrow construction sites and a large number of equipment.
[0003] In some special water conservancy project quality inspection scenarios, such as crossing obstacles like rivers and gullies, it is difficult to deliver the integral measuring rod to the inspection point through conventional transportation methods. Due to its size and weight limitations, it cannot be transported in parts, which forces the inspection personnel to spend more time and effort to find suitable transportation tools or take detours, increasing the difficulty and time cost of the inspection work. Utility Model Content
[0004] The technical problem to be solved by this utility model is that most of the measuring rods used for quality inspection of water conservancy projects in the prior art adopt an integral structure design. The length of the rod is usually determined according to the actual measurement needs, and generally varies from several meters. This integral structure makes the rod take up a lot of space when it is stored and carried. Therefore, we propose a measuring rod for quality inspection of water conservancy projects.
[0005] To achieve the above objectives, this application adopts the following technical solution: a measuring rod for quality inspection of water conservancy projects, comprising a first measuring rod, an adjustment groove at the top of the first measuring rod, a rotating column rotatably connected inside the adjustment groove, a connecting rod inside the rotating column, a second measuring rod fixedly connected to the top of the connecting rod, arc-shaped blocks fixedly connected to both ends inside the adjustment groove, control grooves at both ends of the rotating column, a push block slidably connected inside the control groove, an insertion rod fixedly connected to the side of the push block near the inside of the control groove, and insertion holes at both ends of the connecting rod.
[0006] Preferably, the control groove has sliding grooves on both sides, and the push block has sliders fixedly connected to both sides, with the surface of the sliders slidingly connected to the inside of the sliding grooves.
[0007] Preferably, the size of the insertion rod is adapted to the size of the insertion hole, and the surface of the insertion rod is inserted into the interior of the insertion hole.
[0008] Preferably, a storage spring is fixedly connected to the side of the push block near the insertion rod, and the side of the storage spring away from the push block is fixedly connected to the inside of the control groove.
[0009] Preferably, both ends of the rotating column are provided with shrinkage grooves, and an insertion rod is slidably connected inside the shrinkage groove. A return spring is fixedly connected to the side of the insertion rod near the inside of the shrinkage groove, and the side of the return spring away from the insertion rod is fixedly connected to the inside of the shrinkage groove. Both ends of the first measuring rod are provided with insertion holes.
[0010] Preferably, sliding grooves are provided on both sides of the shrinkage groove, and sliding blocks are fixedly connected to both sides of the insertion rod, with the surface of the sliding block slidingly connected to the interior of the sliding groove.
[0011] Preferably, the adjusting groove has two annular grooves inside, and an annular block is fixedly connected to the outer diameter surface of the rotating column. The surface of the annular block is slidably connected to the inside of the annular groove.
[0012] The technical effects and advantages of this utility model are as follows:
[0013] In this invention, the operator inserts the connecting rod into the inside of the rotating column and rotates the column. As the column rotates, it moves the push block and the insertion rod, causing the push block to contact the thicker end of the arc-shaped block. This causes the arc-shaped block to push the push block, which in turn moves the insertion rod into the insertion hole, thus completing the splicing. This makes it convenient for the operator to transport and carry the first and second measuring rods. Attached Figure Description

[0021] The present invention will now be described in further detail with reference to the accompanying drawings and preferred embodiments. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.
[0022] Reference Figures 1-6 As shown, this utility model provides a technical solution: a measuring rod for quality inspection of water conservancy projects, including a first measuring rod 1. The top of the first measuring rod 1 is provided with an adjustment groove 2. A rotating column 3 is rotatably connected inside the adjustment groove 2. A connecting rod 4 is provided inside the rotating column 3. A second measuring rod 5 is fixedly connected to the top of the connecting rod 4. Arc-shaped blocks 6 are fixedly connected to both ends inside the adjustment groove 2. Control grooves 7 are provided at both ends of the rotating column 3. Push blocks 8 are slidably connected inside the control grooves 7. An insertion rod 9 is fixedly connected to the side of the push block 8 near the inside of the control groove 7. Insertion holes 10 are provided at both ends of the connecting rod 4. By inserting the connecting rod 4 into the inside of the rotating column 3 and rotating the rotating column 3, the rotating column 3 drives the push block 8 and the insertion rod 9 to move, and drives the push block 8 to contact the thicker end of the arc-shaped block 6. The arc-shaped block 6 pushes the push block 8 to drive the insertion rod 9 into the inside of the insertion hole 10, thereby completing the splicing. This facilitates the transportation and carrying of the first measuring rod 1 and the second measuring rod 5 by the staff.
[0023] Reference Figure 4 and Figure 5 As shown in this embodiment: sliding grooves 11 are provided on both sides of the control slot 7, and sliders 12 are fixedly connected to both sides of the push block 8. The surface of the slider 12 is slidably connected to the inside of the sliding groove 11. When the operator moves the push block 8, the push block 8 drives the slider 12 to slide inside the sliding groove 11. Through the above settings, the movement of the push block 8 is more stable, avoiding the push block 8 from shaking or deviating during the movement, thereby improving the stability and reliability of the equipment.
[0024] Reference Figure 4 and Figure 6As shown in this embodiment: the size of the insertion rod 9 is adapted to the size of the insertion hole 10, and the surface of the insertion rod 9 is inserted into the interior of the insertion hole 10. By adapting the size of the insertion rod 9 to the size of the insertion hole 10, the insertion rod 9 can be tightly inserted into the interior of the insertion hole 10, and it is not easy for it to fall off or loosen.
[0025] Reference Figure 4 As shown in this embodiment: a storage spring 13 is fixedly connected to the side of the push block 8 near the insertion rod 9, and the side of the storage spring 13 away from the push block 8 is fixedly connected to the inside of the control groove 7. When the operator pushes the push block 8 to push the insertion rod 9, the push block 8 compresses the storage spring 13 to store force, and drives the insertion rod 9 to be inserted into the insertion hole 10. When the operator releases the push block 8, under the action of the rebound force of the storage spring 13, the push block 8 is quickly pushed to drive the insertion rod 9 to release the limit between it and the insertion hole 10.
[0026] Reference Figure 4 and Figure 5 As shown in this embodiment: both ends of the rotating column 3 are provided with shrinkage grooves 14, and an insertion rod 15 is slidably connected inside the shrinkage groove 14. A return spring 16 is fixedly connected to the side of the insertion rod 15 near the inside of the shrinkage groove 14, and the side of the return spring 16 away from the insertion rod 15 is fixedly connected to the inside of the shrinkage groove 14. Both ends of the first measuring rod 1 are provided with insertion holes 17. When the operator rotates the rotating column 3 to drive the insertion rod 9 into the insertion hole 10, the shrinkage groove 14 and the insertion hole 17 are parallel, and the return spring 16 is also released. Under the action of the rebound force of the return spring 16, the insertion rod 15 is quickly inserted into the inside of the insertion hole 17, so that the rotating column 3 avoids rotation.
[0027] Reference Figure 4 and Figure 5 As shown in this embodiment: sliding grooves 18 are provided on both sides of the shrinkage groove 14, and sliding blocks 19 are fixedly connected to both sides of the insertion rod 15. The surface of the sliding block 19 is slidably connected to the inside of the sliding groove 18. When the operator moves the insertion rod 15, the insertion rod 15 drives the sliding block 19 to slide inside the sliding groove 18. Through the above settings, the stability of the insertion rod 15 during the movement can be guaranteed, and the insertion rod 15 can be prevented from shaking or deviating from the track during the movement, which further improves the practicality and reliability of the device.
[0028] Reference Figure 3 and Figure 4As shown in this embodiment: the inside of the adjusting groove 2 is provided with two annular grooves 20, and the outer diameter surface of the rotating column 3 is fixedly connected with an annular block 21. The surface of the annular block 21 is slidably connected to the inside of the annular groove 20. When the operator rotates the rotating column 3 inside the adjusting groove 2, the rotating column 3 drives the annular block 21 to slide inside the annular groove 20. Through the above setting, the rotating column 3 can be made more stable during rotation, avoiding shaking or jamming caused by rotation, thereby improving the operating efficiency and stability of the entire device.
[0029] Working Principle: The operator inserts the connecting rod 4 into the rotating column 3 and rotates the column. As the column rotates, it moves the push block 8 and the insertion rod 9, causing the push block 8 to contact the thicker end of the arc-shaped block 6. This pushes the push block 8, causing the insertion rod 9 to insert into the insertion hole 10, thus completing the splicing. This facilitates the transport of the first measuring rod 1 and the second measuring rod 5. When the operator moves the push block 8, it causes the slider 12 to slide within the groove 11. This design ensures stable movement of the push block 8, preventing wobbling or deviation during movement, thus improving the stability and reliability of the equipment. The size of the insertion rod 9 is matched to the size of the insertion hole 10, ensuring a tight fit and preventing it from falling out or loosening. When the operator pushes the insertion rod 9 with the push block 8, the push block 8 compresses the storage spring 13, storing energy and causing the insertion rod 9 to insert into the insertion hole 10. When the operator releases the push block 8… Under the action of the rebound force of the storage spring 13, the push block 8 is quickly pushed to release the insertion rod 9 from the limit between it and the insertion hole 10. When the operator rotates the rotating column 3 to insert the insertion rod 9 into the insertion hole 10, the contraction groove 14 is parallel to the insertion hole 17. At the same time, the return spring 16 is also released. Under the action of the rebound force of the return spring 16, the insertion rod 15 is quickly inserted into the insertion hole 17, preventing the rotating column 3 from rotating on its own. When the operator moves the insertion rod 15, the insertion rod 15 drives the sliding block 19 in the sliding groove 18. The sliding mechanism ensures the stability of the insertion rod 15 during movement, preventing it from wobbling or deviating from its track. This further improves the practicality and reliability of the device. When the operator rotates the rotating column 3 inside the adjusting groove 2, the rotating column 3 drives the ring block 21 to slide inside the ring groove 20. This mechanism makes the rotating column 3 more stable during rotation, avoiding wobbling or jamming caused by rotation, thereby improving the overall operating efficiency and stability of the device.
