[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0034] Example:

[0035] like Figures 1-7 As shown, this utility model provides a technical solution: a water level measuring device for water conservancy operation and management, including a fixed rod 1, and further comprising:

[0036] The transmission assembly 2 includes a fixed disk 21 slidably connected to the fixed rod 1, a transmission frame 26 slidably connected to the fixed disk 21, a first sliding shaft 27 slidably connected to the transmission frame 26, a second transmission rod 28 fixedly connected to the first sliding shaft 27, a fixed plate 25 fixedly connected to the transmission frame 26, a first transmission rod 23 slidably connected to the fixed plate 25, the first transmission rod 23 being rotatably connected to the fixed disk 21, and a fourth transmission rod 211 being rotatably connected to the side of the fixed disk 21 away from the first transmission rod 23, the fourth transmission rod 211 being connected to the fixed plate 25.

[0037] The transmission disc 3 is slidably connected to the bottom of the first transmission rod 23 and the fourth transmission rod 211. The transmission disc 3 has an opening, and a second sliding shaft 36 is fixedly connected in the opening. The fixed rod 1 has an opening, and the second sliding shaft 36 is slidably connected in the opening on the fixed rod 1. A torsion spring 11 is rotatably connected to the fixed rod 1, and a mounting disc 32 is rotatably connected to the torsion spring 11. A detector body 35 is fixedly connected to the mounting disc 32.

[0038] In this invention, the motor rotation drives the mounting frame 212 to rotate. The mounting frame 212 drives the second transmission rod 28 to slide the transmission frame 26 on the fixed disk 21. When the transmission frame 26 slides, it drives the first transmission rod 23 to rotate on the first rotating shaft 24. At the same time, it pulls the third transmission rod 210 to move through the universal joint 29. Since the third transmission rod 210 is connected to the fourth transmission rod 211, it drives the fourth transmission rod 211 to rotate on the first rotating shaft 24. The fourth transmission rod 211 and the first transmission rod 23 rotate together, causing the transmission disk 3 to slide down. The second sliding shaft 36 on the transmission disk 3 slides on the fixed rod 1, thereby pulling the end of the fixed rod 1 to retract inward, achieving a tighter connection with the ground. This causes the end of the fixed rod 1 away from the detector body 35 to retract inward and clamp the ground, forming a reinforcement effect similar to a ground anchor. This can actively resist flood impact, soil subsidence, and strong wind loads, and prevent sensor position displacement caused by bracket tilting or collapse.

[0039] Furthermore, such as Figures 1-7 As shown, openings are provided on the side of the fixed disk 21 near the fourth transmission rod 211 and the first transmission rod 23. First rotating shafts 24 are rotatably connected to the openings on both sides of the fixed disk 21. The first transmission rod 23 and the fourth transmission rod 211 are rotatably connected to the openings on both sides of the fixed disk 21 through the first rotating shafts 24 on both sides of the fixed disk 21. By setting the first rotating shafts 24 on both sides of the fixed disk 21 as rotation fulcrums, a movable mechanical connection structure is constructed, so that the first transmission rod 23 and the fourth transmission rod 211 can rotate flexibly around the axis. The opening design avoids the physical interference of the fixed disk 21 on the rotation path of the rods, ensuring that the transmission assembly 2 can smoothly complete the angle change when subjected to force, and providing basic support for subsequent multi-rod linkage.

[0040] like Figure 6 , Figure 7 As shown, a second transmission rod 28 is fixedly connected to the transmission disk 3, and a mounting disk 32 is slidably connected to the second transmission rod 28. A mounting frame 212 is slidably connected to the bottom of the mounting disk 32 near the second transmission rod 28. The second transmission rod 28 is fixedly connected to the mounting frame 212. The second transmission rod 28 serves as an intermediary carrier for the transmission of motor power, converting the rotational motion of the motor in the mounting frame 212 into linear transmission power. The sliding fit design between the mounting disk 32 and the second transmission rod 28 allows the mounting frame 212 to move along the rod direction under the drive of the motor, thereby realizing the tossing operation of the transmission frame 26 and forming a power transmission link from the motor to the transmission assembly 2.

[0041] like Figures 1-2As shown, the bottom of the fixing disc 21 is fixedly connected with a fixing column 22, a rigid connection node of the device with the ground is constructed through the fixing column 22, the bottom of the fixing column 22 is anchored to the ground foundation by means of bolts, a stable support base point is formed, the overall load of the equipment is transmitted to the ground, the dynamic reinforcement effect of the subsequent transmission mechanism is matched, a composite stable system of static anchoring plus dynamic clamping is constructed, and the overturning resistance of the device in a complex environment is improved.

[0043] An opening is formed in the mounting disc 32, and the fifth transmission rod 31 is in sliding connection in the opening in the mounting disc 32, a sliding opening suitable for the fifth transmission rod 31 is formed in the mounting disc 32, a guide constraint structure is constructed, and the movement track of the fifth transmission rod 31 is limited to the vertical direction, so that the vertical transmission of force in the transmission process is guaranteed, transverse deviation of the rod is prevented through mechanical limiting, and it is ensured that the clamping operation of the fixed frame 34 on the detector body 35 is controllable.
