Description

Technical Field

[0001] This utility model relates to the technical field of water level monitoring, and more specifically, to a water level monitoring device. Background Technology

[0002] Water level monitoring is a core function in water conservancy projects and hydropower station operations. Accurate water level data is crucial for the safety of water conservancy facilities, water resource allocation, and flood warning. Currently, traditional water level monitoring relies heavily on electronic sensors. While these sensors can achieve automated monitoring, they have significant limitations in extreme situations—such as power outages causing equipment failures or strong electromagnetic interference leading to data distortion—potentially causing monitoring interruptions and posing risks to water conservancy safety. Therefore, the industry urgently needs a non-electronic backup monitoring device that uses physical vision to monitor water levels, thus compensating for the shortcomings of electronic equipment.

[0003] Existing non-electronic water level monitoring devices mostly use a guide rod with graduated lines as the core, with a float indicating the scale as the water level changes. However, for large bodies of water such as hydropower stations, in order to avoid interference from siltation on the shore and wave reflection, monitoring points often need to be set up in areas far from the shore. In this case, the graduated lines on the guide rod are difficult to clearly see with the naked eye due to the distance, making it impossible for staff to quickly judge water level changes and seriously affecting monitoring efficiency.

[0004] Therefore, in order to solve the above-mentioned technical problems, this utility model proposes a water level monitoring device. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a water level monitoring device.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a water level monitoring device, comprising a guide rod, a float seat disposed on the guide rod, a monitoring component disposed on the float seat, the monitoring component comprising multiple movable floating mechanisms, the multiple movable floating mechanisms being arranged circumferentially around the guide rod; The movable floating mechanism includes a movable part and a floating part, which are connected. The movable part is movably mounted on the float, and the floating part floats on the water surface. The water level can be monitored by observing the distance between multiple floating parts. When multiple floating parts are close to each other, it indicates that the water level is rising; when multiple movable floating mechanisms are far apart, it indicates that the water level is falling. The guide rod is provided with a connection hole.

[0007] Furthermore, the number of active floating mechanisms is at least three.

[0008] Furthermore, the floating part includes a float; the movable part includes a first hinge seat disposed on the float base, the first hinge seat is hinged to a limit rod, one end of the limit rod is hinged to a connecting rod, one end of the connecting rod is hinged to a second hinge seat, and the second hinge seat is connected to the float.

[0009] Furthermore, a power supply compartment is provided inside the guide rod, and a battery is placed inside the power supply compartment. A light source is installed inside the float, and the battery supplies power to the light source.

[0010] Furthermore, a photovoltaic device is installed on the guide rod, which is connected to the battery and charges the battery.

[0011] Furthermore, the float is provided with reflective stickers on its exterior.

[0012] Furthermore, the float is slidably connected to the guide rod, and the float is provided with screws, which fix the float to the guide rod.

[0013] Furthermore, a floating disk is slidably connected to the guide rod, and scale lines are provided on the guide rod.

[0014] Compared with the prior art, the present invention has the following beneficial effects: This utility model, as a non-electronic backup monitoring device, effectively solves the core pain points of water level monitoring in large water bodies, significantly improving the reliability and convenience of monitoring. By setting at least three floats to form a stable triangular support structure, combined with the rigid connection design of the limiting rod and connecting rod, it ensures that the floats accurately move closer to or away from the guide rod as the water level rises and falls. Staff can intuitively judge water level changes by observing the changes in the spacing between the floats, solving the problem of difficulty in identifying scale lines on distant shores. At the same time, the mutual restraining force formed by the distribution of multiple floats greatly reduces the device swaying caused by wind, waves, and water flow, ensuring the vertical state of the guide rod and the stability of the monitoring benchmark, thus improving the accuracy of physical visual monitoring.

[0018] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in this utility model embodiment are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure).

Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature.

[0020] In this utility model, unless otherwise explicitly specified and limited, the terms "connection," "fixing," etc., should be interpreted broadly. For example, "fixing" can mean a fixed connection, a detachable connection, or an integral part; it can mean a mechanical connection or an electrical connection; it can mean a direct connection or an indirect connection through an intermediate medium; it can mean the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0021] Furthermore, the technical solutions of the various embodiments of this utility model can be combined with each other, but only if they are based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.

[0022] like Figures 1-4As shown, this utility model provides a water level monitoring device, including a guide rod 1. The guide rod 1 serves as the support and reference component of the entire device. Its material needs to balance strength and corrosion resistance, and is usually made of high-strength alloy or engineering plastic to adapt to the complex water quality environment that may exist in large water bodies. For example, the water in a hydropower station may contain a certain amount of minerals or impurities. These materials can effectively resist the wear and tear caused by long-term immersion. A float 3 is slidably mounted on the guide rod 1. The design of the float 3 makes full use of the buoyancy principle and uses low-density materials such as plastic or foam. These materials not only ensure that the float 3 floats stably on the water surface, but also have the characteristics of being lightweight and not easily damaged. Even when there are slight fluctuations in the water surface, it can maintain good following performance. The diameter of the groove opened on the float 3 is larger than the diameter of the guide rod 1, which allows the float 3 to slide flexibly on the guide rod 1 without getting stuck due to slight unevenness on the surface of the guide rod 1, ensuring that the float 3 can move up and down accurately with changes in water level. Meanwhile, the guide rod 1 is also evenly equipped with scale lines 15. These scale lines 15 are precisely calibrated, and the minimum scale can be set according to actual monitoring needs. By observing the scale line 15 corresponding to the edge of the float 3, the staff can quickly and clearly know the water level at this time. The operation is simple and intuitive.

[0023] The guide rod 1 is also equipped with a float 9, which is also made of a lightweight and highly buoyant material. The float 9 allows the guide rod 1 to float in the water, ensuring it remains vertical and guaranteeing the accuracy of the scale line 15. One end of the guide rod 1 has a connecting hole 4, through which different sizes of anchor chains or fixing devices can be fitted. The guide rod 1 can be connected to the anchor chain or fixed to the dam via the connecting hole 4, thus providing a stable position and effectively preventing it from drifting away under the impact of water flow or wind, ensuring the stability of the monitoring position.

[0024] Considering the needs of hydropower stations, which often involve large bodies of water, it is necessary to monitor water levels far from the shore to avoid interference from the shore environment. For example, factors such as siltation and wave reflection may cause deviations in water level measurements. However, because these water level monitoring devices are far from the shore, the scale lines 15 on their guide rods 1 are often difficult to clearly identify, causing inconvenience to the monitoring work. Therefore, based on the above embodiment, as shown in Figures 1 and 3, multiple first hinge seats 5 are provided on the float 9. Each first hinge seat 5 is hinged to a limit rod 6. The limit rod 6 is made of high-strength plastic rod to ensure that it is not easily bent or deformed under force. One end of the limit rod 6 is rotatably connected to the float 7 through a connecting rod 12. The limit rod 6 is hinged to the connecting rod 12 through a bolt structure. A second hinge seat 13 is provided on the float 7. The second hinge seat 13 is hinged to the connecting rod 12 to ensure flexible rotation between the connecting rod 12 and the float 7.

[0025] Typically, there are at least three floats 7. Three or more floats 7 form a stable triangular support structure, enhancing the stability of the entire water level monitoring device. Multiple floats 7 can be attached to the water surface and simultaneously move the limiting rod 6. Because the limiting rod 6 is restricted by the first hinge 5, its rotation trajectory is fixed. Therefore, when the water level rises, the floats 7 need to rise with the water surface, causing the limiting rod 6 to rotate upwards based on the first hinge 5. Simultaneously, the floats 7 move closer to the guide rod 1 under the influence of the limiting rod 6's rotation. Conversely, when the water level falls, the floats 7 sink, causing the limiting rod 6 to rotate downwards, and the floats 7 move away from the guide rod 1. By observing the changes in the distance between the floats 7, staff can roughly determine whether the water level is rising or falling, achieving convenient water level monitoring. Furthermore, the floats 7 are relatively large, typically with a diameter between 30-50 cm. Even when placed far from the observation point, the changes in the distance between the floats 7 can be clearly observed with the naked eye, solving the problem of the distant shore scale line 15 being difficult to identify.

[0026] In addition to monitoring water levels, the multiple floats 7 also stabilize the entire water level monitoring device. When there are waves or fluctuations in the water surface, the multiple floats 7, distributed in different positions, can form a mutually counteracting force, reducing the shaking of the device and keeping the guide rod 1 in a relatively stable state, thus improving the accuracy of monitoring.

[0027] It is worth noting that the float 7 and the limiting rod 6 are directly rigidly connected through the connecting rod 12. Compared with the rope connection, this connection method can effectively prevent the float 7 and the limiting rod 6 from shifting due to rope slackness or swing, ensuring that the movement trajectory of the float 7 is always precisely correlated with the rotation of the limiting rod 6, thereby making the measurement results more accurate and reliable.

[0028] In addition, the float 9 has a groove for the guide rod 1 to pass through, and a screw 16 is also provided on the float 9. One end of the screw 16 extends into the groove. By adjusting the position of the float 9 on the guide rod 1, the operator can flexibly adjust it according to different water level ranges, water depths, and other conditions, enhancing the practicality of the device. After the float 9 is adjusted to a suitable position on the guide rod 1, the screw 16 is tightened. The end of the screw 16 will press tightly against the surface of the guide rod 1, generating sufficient friction to fix the float 9 on the guide rod 1 and prevent it from shifting during the operation of the device.

[0029] To ensure visibility of the buoy 7 even in low-light conditions, such as at night or in rainy weather, the buoy 7 is made of transparent or semi-transparent materials, such as acrylic or polycarbonate. These materials not only have good light transmittance but also good impact resistance and weather resistance. A light source 14 is installed inside the buoy 7, preferably a low-power LED light. LED lights have advantages such as low energy consumption, long lifespan, and stable brightness, reducing energy consumption while ensuring lighting effects. The guide rod 1 is hollow, a design that not only reduces its weight and facilitates buoyancy but also provides space for internal wiring. A power compartment 11 is located inside the guide rod 1, housing a battery 10. The battery 10 is a rechargeable battery, such as a lithium battery, providing continuous power to the light source 14. The battery 10 is connected to the light source 14 via a wiring harness arranged in grooves inside or on the surface of the limiting rod 6, preventing the wiring harness from being exposed to water flow and waves, ensuring stable power transmission. The light source 14 can illuminate the floats 7, so that even in poor lighting conditions, staff can clearly observe the positional relationship between the floats 7 through the illuminated floats 7, ensuring the normal operation of monitoring work at night or in bad weather.

[0030] In addition, to improve the endurance of the light source 14 and reduce the frequency of battery replacement 10, a photovoltaic device 2 is installed on the guide rod 1. The photovoltaic device 2 typically includes a solar panel 10 and a charging controller. The solar panel 10 protrudes above the water surface to fully receive sunlight, generating electricity through solar power and charging the battery 10 under the action of the charging controller, thus achieving sustainable energy utilization. To prevent the float 7 from failing to emit light due to a malfunction of the battery 10 or the light source 14, a reflective sticker 8 is also installed on the float 7. The reflective sticker 8 is made of a material with a high reflectivity, which can reflect bright light under external light such as moonlight or flashlight beam, making it easier for staff to observe the position of the float 7 and further improving the reliability of the device.

[0031] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model in any way. Those skilled in the art can readily implement this utility model based on the accompanying drawings and the above description. However, any modifications, alterations, or equivalent variations made by those skilled in the art without departing from the scope of the utility model's technical solution, utilizing the disclosed technical content, are considered equivalent embodiments of this utility model. Furthermore, any equivalent changes, alterations, or variations made to the above embodiments based on the essential technology of this utility model are still within the protection scope of this utility model's technical solution.
