Description

Technical Field

[0001] This utility model relates to the field of water level benchmarks, and more specifically, to a water level benchmark for water conservancy and hydropower projects. Background Technology

[0002] Water level benchmarks are fundamental tools for water level monitoring in water conservancy and hydropower projects, widely used in monitoring water levels in rivers, reservoirs, canals, and other water bodies. Accurate water level data is of great guiding significance for engineering decisions such as flood control scheduling, irrigation management, power generation operation, and water environment management.

[0003] Currently, most water level markers used in water conservancy and hydropower projects are rod-shaped structures, fixed at the bottom by inserting into the riverbed soil or connecting to a pre-embedded base. The main body of the marker has water level markings, and observers determine the water level by reading the corresponding position of the water surface and the markings. However, these markers are susceptible to tilting due to the impact of water flow. Water level markers are constantly subjected to the impact of water flow, especially in areas with high current speeds or strong waves. The impact force of the water flow on the marker is significant, easily causing it to sway or even tilt. Furthermore, the structure of multi-section markers connected by screws is prone to loosening of the threads due to water flow impact after prolonged use, leading to a shift in the overall verticality of the marker. Once the marker tilts, its markings deviate from the vertical direction, directly affecting the accuracy of the water level readings. Therefore, we propose a new type of water level marker for water conservancy and hydropower projects. Utility Model Content

[0004] The purpose of this invention is to solve the problem that the accuracy of reading is affected by the tilting of the current marker caused by water flow.

[0005] To achieve the aforementioned objectives and address the aforementioned problems, this utility model provides a water level indicator for hydropower projects, comprising a base, a connector fixedly connected to the upper surface of the base, a marker rod mounted on the connector, a threaded hole at the upper end of the marker rod, a fixed plate on the upper side of the marker rod, a threaded post fixedly connected to the lower surface of the fixed plate, the threaded post being threadedly connected to the threaded hole, a plurality of connecting rods fixedly connected to the outer surface of the fixed plate, a top plate fixedly connected to the end of each connecting rod, a mounting base fixedly connected to the lower surface of the top plate, a movable ball movably connected to the mounting base, a vertical rod fixedly mounted on the movable ball, a counterweight fixedly connected to the lower end of the vertical rod, and an indicating component mounted on the fixed plate.

[0006] As a preferred technical solution of this application, the indicator component includes two arc-shaped indicator plates, both of which are fixedly connected to the upper surface of the fixed disk, and the two arc-shaped indicator plates are arranged crosswise.

[0007] As a preferred technical solution of this application, both of the arc-shaped indicator plates are provided with angle indicators, and the outer surface of the indicator rod is provided with a water level indicator.

[0008] As a preferred technical solution of this application, a movable ring is movably fitted on the outer surface of the marker, and a gap is provided between the inner wall of the movable ring and the marker.

[0009] As a preferred technical solution of this application, a buoyancy disk is fixedly connected to the outer surface of the movable ring.

[0010] As a preferred technical solution of this application, a lever is fixedly connected to the outer surface of the buoyancy disk, and the lever is inclined.

[0011] As a preferred technical solution of this application, the connector is provided with a fixing pin.

[0012] As a preferred technical solution of this application, the lower end of the fixing pin slides through to the lower surface of the base.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: In the scheme of this application: 1. Through the cooperation of structures such as base, plug-in seat, marker rod, threaded hole, fixed plate, threaded column, connecting rod, top plate, mounting seat, movable ball, vertical rod, counterweight, arc-shaped indicator plate, and angle indicator, when the marker rod tilts due to water flow impact, the counterweight drives the vertical rod to always remain vertical, and the arc-shaped indicator plate tilts synchronously with the marker rod. The tilt angle can be directly read through the angle indicator, and then the true water depth can be obtained by calculation and correction through formula. This realizes the function of intuitively prompting observers when the marker rod tilts and assisting in correcting readings, effectively solving the problem of water level data distortion caused by marker rod tilt. 2. Through the cooperation of structures such as the marker, movable ring, buoyancy disc, and lever, the buoyancy disc rises and falls with the water surface, causing the movable ring to slide up and down along the marker. The inclined lever generates a tangential force under the impact of the water flow, driving the buoyancy disc and movable ring to rotate continuously around the marker. This achieves continuous dispersion and clearing of floating objects near the marker, preventing debris from accumulating and obstructing the water level indicator, and improving the convenience and reliability of water level reading.

Detailed Implementation

[0016] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention 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 invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.

[0017] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.

[0018] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0019] Example 1 Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 A water level indicator for water conservancy and hydropower includes a base 1. A connector 2 is fixedly connected to the upper surface of the base 1. A marker 3 for displaying the water level is provided on the connector 2. A threaded hole 4 is opened at the upper end of the marker 3. A fixed plate 5 is provided on the upper side of the marker 3. A threaded post 6 for connecting is fixedly connected to the lower surface of the fixed plate 5. The threaded post 6 is threadedly connected to the threaded hole 4. A plurality of connecting rods 7 are fixedly connected to the outer surface of the fixed plate 5. A top plate 8 is fixedly connected to the end of the connecting rod 7. A mounting base 9 is fixedly connected to the lower surface of the top plate 8. A movable ball 10 is movably connected to the mounting base 9. A vertical rod 11 for indicating the level is fixed on the movable ball 10. A counterweight 12 is fixedly connected to the lower end of the vertical rod 11. An indicating component is provided on the fixed plate 5.

[0020] The marker 3 is fixed by the plug-in connector 2, and the fixed plate 5 is fixed by the threaded post 6 and the threaded hole 4. The vertical rod 11 is always perpendicular to the horizontal plane by gravity and the counterweight 12. The movable ball 10 provides rotation space for the vertical rod 11. When the marker 3 tilts due to the ground depression caused by water flow, the tilt of the marker 3 can be judged by the intersection of the vertical rod 11 and the connecting rod 7 or the marker 3.

[0021] Example 2 The water level benchmark for water conservancy and hydropower provided in Example 1 has been further optimized, specifically, as follows: Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, the indicator assembly includes two arc-shaped indicator plates 13 for indicating tilt angles. Both arc-shaped indicator plates 13 are fixedly connected to the upper surface of the fixed plate 5. The two arc-shaped indicator plates 13 are arranged crosswise. An angle indicator 14 is provided on each of the two arc-shaped indicator plates 13. A water level indicator 15 is provided on the outer surface of the rod 3. A movable ring 16 is movably fitted on the outer surface of the rod 3. A gap is provided between the inner wall of the movable ring 16 and the rod 3. A buoyancy disk 17 for providing buoyancy is fixedly connected to the outer surface of the movable ring 16. A lever 18 is fixedly connected to the outer surface of the buoyancy disk 17. The lever 18 is inclined. A fixing pin 19 is provided on the plug-in seat 2. The lower end of the fixing pin 19 slides through to the lower surface of the base 1.

[0022] Furthermore, after the marker 3 is tilted, the tilt angle can be read using two staggered arc-shaped indicator plates 13 in conjunction with the counterweight 12. Then, the true water depth can be calculated by reading the water depth along the tilted rod × cos(θ), where θ is the tilt angle. At the same time, the fixed pin 19 can improve the stability of the base 1 connection and prevent the marker 3 from tilting due to the shaking of the base 1. Meanwhile, the buoyancy plate 17 can make the lever 18 and the movable ring 16 rise with the rise of the water level. At the same time, the water flow pushes the lever 18, which in turn pushes the buoyancy plate 17 to rotate. When the lever 18 rotates, it can push away the surrounding floating objects, reduce the floating objects accumulated near the marker 3, and increase the convenience of reading.

[0023] The application process of the water level benchmark for water conservancy and hydropower provided by this utility model is as follows: First, during the installation phase of the marker 3, the base 1 is fixed to the riverbed or pre-buried foundation of the target water area. The marker 3 is positioned and installed using the plug-in connector 2, and the base 1 is further reinforced by the fixing pin 19 to improve the overall structure's impact resistance and stability. The fixing plate 5 is threadedly fixed to the upper end of the marker 3 through the threaded post 6 on its lower side, thus completing the assembly of the upper structure.

[0024] During use, when the marker 3 tilts due to long-term water flow impact, foundation settlement, or external collisions, the vertical rod 11 remains vertical under the weight of the counterweight 12. The movable ball 10 provides the vertical rod 11 with omnidirectional rotation space, allowing it to swing freely relative to the tilted marker 3 and the fixed plate 5. Simultaneously, the two arc-shaped indicator plates 13, fixedly connected to the upper surface of the fixed plate 5, tilt along with the marker 3, while the vertical rod 11 remains vertical. This creates an angle difference between the vertical rod 11 and the arc-shaped indicator plates 13, which is the tilt angle of the marker 3. Observers can directly read this tilt angle value using the angle indicator 14 set on the arc-shaped indicator plate 13.

[0025] After obtaining the tilt angle θ, the observer reads the scale value of the water level indicator 15 corresponding to the water surface along the tilted pole 3, and records it as the reading along the pole L. Substituting it into the formula: true water depth = L × cosθ, the corrected true water level data can be calculated, effectively avoiding the error caused by directly reading the scale due to the tilt of the pole 3.

[0026] In addition, during normal water level monitoring, the movable ring 16 is movably fitted onto the outer surface of the marker 3 with a gap between it and the marker 3, allowing it to slide freely up and down along the marker 3. The buoyancy disk 17 is fixedly connected to the outer surface of the movable ring 16 and floats up and down with the rise and fall of the water level under the action of buoyancy. The lever 18 is fixed to the outer surface of the buoyancy disk 17 and is inclined. When the water flow direction remains constant, the water flow impacts the inclined lever 18, generating a tangential force that pushes the buoyancy disk 17 and the movable ring 16 to rotate slowly and continuously around the marker 3. The rotating lever 18 can continuously disperse floating objects (such as aquatic plants, branches, fallen leaves, etc.) accumulated near the marker 3, preventing debris from accumulating around the marker 3, thereby ensuring that the water level indicator 15 is clearly visible and easy for observers to read accurately.
