[0002] The main function of measuring poles in rivers, canals, etc. is to help surveyors measure water levels, depths and other data. Taking into account the special needs of water transport engineering measurements, such as wind and wave resistance and stability in water, and saving manpower, fixed devices are added to the poles, making the use of the poles more convenient and the measurement data more accurate. It is an indispensable and important tool in modern water transport engineering.

[0003] Currently, surveying operations require the use of a measuring instrument in conjunction with a benchmark. The benchmark fixing device used is generally a bracket placed on the ship, which is connected to the benchmark to improve the stability of the benchmark, so that the benchmark can stand alone in the water, saving manpower.

[0004] Although the currently used benchmark fixing device for water transport engineering measurement can maintain balance without the help of manpower, it is not stable enough due to the different water flow conditions in each water area and the sediment on the bottom of the water by placing a bracket on the ship. Usually, manpower is still needed to fix it, which makes it difficult to effectively measure in complex waters, resulting in inaccurate measurement results and a waste of manpower. Therefore, a benchmark fixing device for water transport engineering measurement is proposed to solve the above problems. Utility Model Content

One side of the movable rod 1 is fixedly connected to the mobile box 4, and the interior of the mobile box 4 is fixedly connected to the spring 2 21. The other end of the spring 21 is fixedly connected to the clamping claw 6, and the clamping claw 6 The end is made of rubber material to increase the friction of the clamping end and improve the stability of the clamping claw 6 during work. The internal sliding connection of the clamping claw 6 is connected with the connecting rod 22. The clamping claw 6 is driven to move on the periphery of the connecting rod 22 by the expansion and contraction of the spring 21. The two ends of the connecting rod 22 are fixedly connected to the inside of the mobile box 4. The interior of the clamping claw 6 is fixedly connected with the connecting rod 1 20. The two ends of the connecting rod 1 20 are connected to the internal sliding connection of the mobile box 4. Under the action of the connecting rod 1 20, the clamping claw 6 is more stable during work. The internal sliding connection of the mobile box 4 is connected with a push rod 19. One end of the push rod 19 is slidably connected to one end of the clamping claw 6. When the push rod 19 is squeezed, the spring 21 will be squeezed through the clamping claw 6, so as to achieve the clamping and opening of the clamping claw 6. The inside of the clamping claw 6 is slidably connected with the benchmark 7. The clamping claw 6 is used to clamp the benchmark 7. By squeezing the push rod 19, the clamping claw 6 is opened under the action of the spring 21 and the connecting rod 22, so that the benchmark 7 is placed inside the clamping claw 6 to achieve the installation of the benchmark 7.

[0033] Reference Figure 1 and Figure 3The top of the locking block 5 is fixedly connected with a disassembly assembly for disassembling and installing the sliding frame 3. The disassembly assembly includes a connecting block 12. The bottom of the connecting block 12 is fixedly connected to the top of the locking block 5. The outer periphery of the connecting block 12 is slidably connected to the inner side of the sliding frame 3, so that the sliding frame 3 can slide on the outer periphery of the connecting block 12. The inner rotation of the connecting block 12 is connected to a knob 15. The inner part of the knob 15 is fixedly connected to a pull rope 17. The pull rope is retracted by rotating the knob 15. Both ends of the pull rope 17 are fixedly connected to a card block 13. The inner part of the card block 13 is connected to the inner part of the card block 13. A spring 18 is fixedly connected to the side, and one end of the spring 18 is fixedly connected to the gasket 16. By rotating the knob 15, the pull rope 17 is contracted, thereby driving the spring 18 to squeeze the spring 18 under the action of the block 13 and the gasket 16.

[0034] Reference Figure 1 、 Figure 3 and Figure 4 The interior of the fixed block 2 is slidably connected with a screw 2 11, and the outer side of the screw 2 11 is threadedly connected with a nut 2 10. The threaded connection between the screw 2 11 and the nut 2 10 makes the tightness of the fixed block 2 adjustable. There are two clamping blocks 13 and two slots 14. The two clamping blocks 13 are slidably connected in the two slots 14, so that the stability of the sliding frame 3 is higher in the installed state. There are two gaskets 16, and the middle parts of the two gaskets 16 are slidably connected to the outer periphery of the pull rope 17.

[0035] Working principle: First, install the locking block 5 to the hull through the screw 9 and nut 8. When the knob 15 is turned, the pull rope 17 will drive the clamping block 13 through the gasket 16 to squeeze the spring 18, so that the clamping block 13 can be separated from the inside of the card slot 14, thereby completing the installation of the sliding frame 3. Therefore, repeating the above operation can complete the disassembly of the sliding frame 3. By turning the nut 2 10 under the action of the screw 2 11, the tightness of the fixing block 2 can be adjusted. When the fixing block 2 is loosened, the movable rod 1 can be moved forward. After adjustment, turn nut 2 10 to clamp the fixed block 2 and the movable rod 1. When the benchmark rod 7 is clamped, the spring 21 is forced to shrink by squeezing the push rod 19, thereby driving the clamping claw 6 to slide outward on the outer periphery of the connecting rod 22 and the connecting rod 1 29 to slide on the inner side of the movable box 4, so that the clamping claw 6 can be opened. When the push rod 19 is released, the tension of the spring 21 will drive the clamping claw 6 to slide in the outer box of the connecting rod 22, thereby clamping the benchmark rod 7.
