[0002] In the construction of water conservancy and hydropower projects, water level measuring devices play a crucial role, serving as key equipment to ensure project quality, construction safety, and progress. Their core function is to obtain real-time and accurate water level data of the construction area, providing a basis for many key processes. For example, during dam construction, water level measurement is needed to control the water level in the surrounding waters to prevent abnormal water levels from affecting the stability of the dam structure. Therefore, the reliability and accuracy of water level measuring devices are directly related to the overall construction quality and safety benefits of water conservancy and hydropower projects.
[0003] In existing technologies, when measuring areas with fast water flow, the measuring instruments lack effective guiding and anti-interference structures. Existing measuring instruments generally use ropes connected to counterweights, and the water level depth is obtained based on the rope's lowering distance. However, when measuring in areas with fast water flow, the stability of the measuring instrument during the sinking process is poor, and the rope in the measuring instrument is easily curved due to the impact of the water flow, leading to inaccurate rope lowering distance and deviation of the measurement point at the bottom of the water. The measurement efficiency and accuracy are difficult to meet the requirements of water conservancy and hydropower construction. Therefore, this utility model provides a water level measuring device for water conservancy and hydropower construction. Utility Model Content
[0004] To overcome the shortcomings of existing technologies and address the lack of effective guiding and anti-interference structures in measuring instruments when measuring areas with high water flow velocity, current measuring instruments typically use ropes connected to counterweights. The water depth is obtained based on the rope's lowering distance. However, when measuring in areas with high water flow, the stability of the measuring instrument during the sinking process is poor, and the rope in the measuring instrument is prone to arcing due to the impact of the water flow. This leads to inaccurate rope lowering distance and deviation of the measurement point at the bottom of the water. Consequently, the measurement efficiency and accuracy are difficult to meet the requirements of water conservancy and hydropower construction.

[0020] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0021] Example 1
[0022] like Figures 1 to 5 As shown in the figure, a water level measuring device for water conservancy and hydropower construction according to an embodiment of the present invention includes a workbench 1; the top of the workbench 1 has a through hole 11, the bottom of the workbench 1 has an extension kit, the top of the workbench 1 is fixedly connected to a motor 12 and a fixing block, the output end of the motor 12 is fixedly connected to a rotating shaft 13, and the rotating shaft 13 is rotatably connected to the side wall of the fixing block, a winding roller 14 is sleeved on the rotating shaft 13; a rope 15 is provided on the winding roller 14, the bottom end of the rope 15 passes through the through hole 11 and is fixedly connected to a lead block 16, the lead block 16 has a conical cross section and the conical tip is set downward; when working, the motor 12 is started, the motor 12 drives the rotating shaft 13 to rotate, the rotating shaft 13 causes the winding roller 14 to rotate, the winding roller 14 releases the rope 15, the rope 15 carries the lead block 16 with the conical tip pointing downward through the through hole 11, the lead block 16 sinks under the action of gravity until it contacts the water surface, and the water level height is calculated by recording the length of the rope 15 released by the winding roller 14.
[0023] The extension kit includes an outer cylinder 2, which is fixed to the bottom of the workbench 1. The center of the outer cylinder 2 corresponds to the center of the through hole 11. An extension cylinder 21 is fitted inside the outer cylinder 2. The cross-sections of the outer cylinder 2 and the extension cylinder 21 are L-shaped and Z-shaped, respectively. The top end of the extension cylinder 21 is adapted to the bottom end of the outer cylinder 2, and the bottom and top of a pair of adjacent extension cylinders 21 are adapted to each other. The top of the lead block 16 corresponds to the bottom of the outer cylinder 2 and the extension cylinder 21. During operation, when the lead block 16 needs to sink deeper, the extension cylinder 21 extends out from the outer cylinder 2. Because the cross-sections of the outer cylinder 2 and the extension cylinder 21 are L-shaped and Z-shaped, respectively... The shape is such that the bottom and top of the adjacent extension tubes 21 are adapted to each other, so that they can be connected and hooked section by section. The setting of the outer tube 2 and the extension tube 21 allows the lead block 16 to fall to the ground when the water level is not deep and the extension tube 21 is not fully extended, so the depth can be measured. If the water flow is too strong and the water level is deep, the extension tube 21 may not touch the bottom when fully extended. At this time, the extension tube 21 is located in the upper part of the water flow, where the water flow speed is the fastest. This can avoid the problem of the water flow impacting the rope 15 into an arc shape. The extension tube 21 retracts according to the movement of the lead block 16 driven by the rope 15.
[0024] Example 2
[0025] like Figures 1 to 5 As shown, a locking groove 3 is provided on the rotating shaft 13, a locking block 31 is fixedly connected to the inner wall of the take-up roller 14, and the locking block 31 is slidably connected in the locking groove 3. A fixing ring 32 is rotatably connected to the end of the take-up roller 14, and a limiting block 33 is fixedly connected to the fixing ring 32. A limiting groove 34 is provided on the top of the worktable 1, and the limiting block 33 is slidably connected in the limiting groove 34. A power component is provided near the fixed ring 32, and the reciprocating movement of the take-up roller 14 is controlled by... Driven by a power component, during operation, the power component drives the fixed ring 32 to move, and the limiting block 33 on the fixed ring 32 slides along the limiting groove 34, while simultaneously driving the take-up roller 14 to move; the locking block 31 on the inner wall of the take-up roller 14 slides in the locking groove 3 of the rotating shaft 13. When the rotating shaft 13 rotates, the take-up roller 14 releases or retracts the rope 15 with its rotation, and also moves back and forth with the fixed ring 32, so that the rope 15 is evenly wound on the take-up roller 14, preventing the rope 15 from getting tangled.
[0026] The power component includes support blocks; a pair of support blocks are fixedly connected to the top of the workbench 1, and a first shaft 4 is rotatably connected between the opposite sidewalls of the pair of support blocks. A rotating wheel 41 is fixedly connected to the first shaft 4, and a circulation groove 42 is provided on the rotating wheel 41. A guide post 43 is fixedly connected to the outer circular wall of the fixed ring 32, and the guide post 43 is slidably connected in the circulation groove 42; gears 44 are fixedly connected to the rotating shaft 13 on the first shaft 4, and the pair of gears 44 mesh with each other; during operation, the motor 12 drives the rotating shaft 13 to rotate, and the gears 44 on the rotating shaft 13 drive the gears 44 on the first shaft 4 to rotate, so that the first shaft 4 and the rotating wheel 41 rotate; the circulation groove 42 of the rotating wheel 41 drives the guide post 43 on the fixed ring 32 to move, thereby allowing the fixed ring 32 to drive the winding roller 14 to move back and forth; at the same time, the rotating shaft 13 drives the winding roller 14 to rotate, so as to achieve uniform winding and unwinding of the rope 15 and ensure smooth measurement process.
[0027] A set of hooks 5 are fixed to the conical surface of the lead block 16. When the lead block 16 sinks to the bottom during operation, the hooks 5 can hook onto underwater weeds or stones to prevent the lead block 16 from being moved by the water flow.
[0028] Working principle: When the device is working, the motor 12 drives the rotating shaft 13 to rotate, which drives the take-up roller 14 to release the rope 15. The rope 15 pulls the conical lead block 16 through the through hole 11 and sinks. In shallow water, the lead block 16 directly touches the bottom, and the water level is measured by the length of the rope 15 released by the take-up roller 14. In deep water, the Z-shaped extension tube 21 of the extension kit extends from the L-shaped outer tube 2 to form a guide channel to prevent the water flow from impacting the rope 15 and causing it to be arc-shaped. At the same time, the gear 44 on the rotating shaft 13 drives the first shaft 4 gear 44 to rotate, which causes the rotating wheel 41 to move through the circulation groove 42 and the guide column 43 to drive the fixed ring 32 to move. This allows the take-up roller 14 to move back and forth while rotating and releasing the rope, ensuring that the rope 15 is evenly wound. After the lead block 16 touches the bottom, the conical hook 5 hooks and fixes the underwater debris, completing the water level measurement.
