Description

Technical Field

[0001] This invention relates to the field of water level measurement technology, and specifically to a water level measurement device for river monitoring. Background Technology

[0002] Water level is the most direct factor reflecting the water condition of a water body. Its changes are mainly caused by the increase or decrease in the amount of water in the body. Water level monitoring is an indispensable part of water conservancy project monitoring.

[0003] Currently, water level gauges are commonly used to monitor river water levels. However, traditional water level gauges are mostly simple in structure and require manual measurement. Furthermore, the surface of the water level gauge is easily contaminated by pollutants, resulting in unclear readings and an inability to provide timely feedback on water level information. To address this issue, a Chinese patent discloses a water level monitoring device (authorization announcement number CN218238997U). This patent involves sliding a floating plate and a sliding sleeve on the surface of a sliding rod. The floating plate floats under the buoyancy of the water flow, while the sliding sleeve slides on the surface of the scale. A shovel at the bottom of the floating plate slides across the surface of the scale as the water level changes, removing any adhering substances from the scale surface and preventing contamination from the water from causing unclear readings.

[0004] However, the aforementioned public documents still have some shortcomings, as they cannot reflect changes in river water levels in real time when monitoring river water levels. Summary of the Invention

[0005] In view of the above-mentioned shortcomings of the existing technology, the present invention provides a river monitoring water level measuring device, which can effectively solve the problems that the existing technology cannot record real-time changes in river water level and does not have early warning capabilities.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] This invention provides a water level measuring device for river monitoring, including a fixing frame, and further comprising:

[0008] The measuring assembly includes a measuring cylinder disposed in the river channel and a floating plate movably installed inside the measuring cylinder. The top of the measuring cylinder is provided with a fixed cover, the measuring cylinder is provided with a rope connected to the floating plate, and the bottom of the measuring cylinder is provided with a water passage pipe.

[0009] The recording component includes a gear rotatably mounted on a fixed cover and driven by a rope, a movable plate slidably connected to the fixed cover and driven by the gear, an inclined guide groove on the movable plate, a transmitting probe extending into the inclined guide groove slidably mounted on the fixed cover, and a receiving screen located above the transmitting probe on the fixed cover.

[0010] Furthermore, the rope is mounted on the measuring cylinder via multiple sets of rotating wheels, and the gear is coaxially mounted with the rotating wheels. The floating disc is equipped with a limiting component connected to the rope. When the floating disc rises or falls due to buoyancy, it moves the rope, thereby driving the gear to rotate.

[0011] Furthermore, the bottom of the movable plate is provided with a rack that meshes with the gear, and the transmitting probe is set on the fixed cover through a guide bar. The direction of the guide bar is perpendicular to the rack in the same horizontal plane, and the transmitting probe and the guide bar are slidably connected. When the gear drives the movable plate to move, the inclined guide groove will guide the transmitting probe to move, and the direction of movement of the transmitting probe is perpendicular to the direction of movement of the movable plate under the restriction of the guide bar.

[0012] Furthermore, the mounting frame is equipped with an information display screen, which is communicatively connected to the receiving screen. When the transmitting probe moves, it sends a signal to the receiving screen, which is then displayed and recorded through the information display screen.

[0013] Furthermore, the bottom of the measuring cylinder is provided with a mounting base, and the measuring cylinder is provided with a spring-shaped guide groove.

[0014] Furthermore, it also includes a warning component that is movably mounted on the floating platform. The warning component includes a buzzer that is rotatably mounted on the floating platform, and the side of the buzzer is provided with a guide block that extends into a spring-shaped guide groove. When the water level in the river rises rapidly, the floating platform pushes the buzzer up and, in conjunction with the spring-shaped guide groove, drives the buzzer to rotate rapidly.

[0015] Furthermore, the buzzer has a power supply inside, and electrode plates that are electrically connected to the positive and negative poles of the power supply are provided inside the buzzer. A conductive strip is elastically installed inside the buzzer, and a conductive plate is provided on the side of the conductive strip near the center of the buzzer.

[0016] Furthermore, the conductive strip and the buzzer are slidably connected, and the sliding direction of the conductive strip is towards the center of the buzzer and away from the center of the buzzer. An elastic element is provided between the conductive strip and the buzzer. The elastic element is used to always push the conductive strip towards the center of the buzzer, that is, in the initial state, the conductive sheet on the conductive strip is not in contact with the electrode sheet.

[0017] Furthermore, a sound amplification cover is provided between the top of the measuring cylinder and the fixed cover.

[0018] Beneficial effects

[0019] The technical solution provided by this invention has the following advantages compared with the known prior art:

[0020] 1. The measuring cylinder is kept in contact with the river water flow through a water pipe on the measuring cylinder. Under the siphon principle, the float is at the same height as the river water level when the water level rises or falls. At this time, the limit device drives the rope to move, which in turn drives the gear to rotate with the rotating wheel. Finally, the rack moves the movable plate. When the movable plate moves, the position changes, which guides the transmitting probe to slide on the guide bar and send the signal to the receiving screen. Finally, the information is recorded and displayed on the information display screen. This method can effectively monitor and record the river water level, making it easy to find changes in the river water level.

[0021] 2. When the water level in the river rises rapidly, the float will push the warning component to rise rapidly. At this time, the guide block on the buzzer will cooperate with the spring-shaped guide groove inside the measuring cylinder, causing the warning component to rotate during rapid ascent. Under the action of centrifugal force, the two sets of conductive strips will be thrown to one side of the inner wall of the measuring cylinder. At this time, the conductive plates set on the conductive strips will contact the electrode plates, thereby connecting the power supply and the buzzer. The buzzer will then sound to provide an early warning. At the same time, the loudspeaker can amplify the sound of the buzzer to improve the warning effect. Attached Figure Description

[0030] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0031] The present invention will be further described below with reference to embodiments.

[0032] See attached document Figure 1-6 A water level measuring device for river monitoring includes a mounting frame 1, which is installed on a riverbank and has a solar panel mounted on it. The solar panel converts solar energy into electrical energy to power the device, thus saving energy. The device also includes:

[0033] Measurement component 2 includes a measuring cylinder 21 installed in the river channel and a floating plate 25 movably installed inside the measuring cylinder 21. A mounting base 213 is provided at the bottom of the measuring cylinder 21. The measuring cylinder 21 is connected to the fixing frame 1 via a bracket, and the mounting base 213 also helps to fix the measuring cylinder 21, preventing instability caused by river water impact. A fixing cover 22 is provided at the top of the measuring cylinder 21. The fixing cover 22 is used to prevent rainwater and debris from entering the measuring cylinder 21 and also serves as a support for the installation of subsequent components. A rope 24 connected to the floating plate 25 is provided on the measuring cylinder 21. The rope 24 is set via multiple sets of rotating pulleys 241. On the measuring cylinder 21, part of the rope 24 is located inside the measuring cylinder 21 and the other part is located outside the measuring cylinder 21. When the float 25 is raised or lowered by buoyancy, the rope 24 is driven to move on the rotating wheel 241. The bottom of the measuring cylinder 21 is provided with a water pipe 212. The water pipe 212 is used to keep the measuring cylinder 21 always connected to the water flow in the river. The water inlet of the water pipe 212 faces the same direction as the water flow in the river and faces the downstream direction of the river. This can prevent debris in the water flow from entering the measuring cylinder 21. Due to the water pipe 212, the water level in the measuring cylinder 21 will always be consistent with the water level in the river through the siphon principle.

[0034] The system includes a recording component 23 for monitoring changes in river water level. The recording component 23 includes a gear 231 rotatably mounted on a fixed cover 22 and driven by a rope 24, and a movable plate 232 slidably connected to the fixed cover 22 and driven by the gear 231. The movable plate 232 is provided with an inclined guide groove 2321. A transmitting probe 234 extending into the inclined guide groove 2321 is slidably mounted on the fixed cover 22. When the movable plate 232 moves, it guides the transmitting probe 234 to slide within the inclined guide groove 2321. By changing the direction of movement of the movable plate 232, the transmitting probe 234 is guided to move in different directions to record changes in river water level. A receiving screen 235 is provided on the fixed cover 22 above the transmitting probe 234. When the transmitting probe 234 moves, it sends information to the receiving screen 235 to reflect changes in river water level.

[0035] Specifically, gear 231 is coaxially arranged with rotating wheel 241. Rotating wheel 241 rotates under the drive of rope 24. The floating plate 25 is provided with limiting member 251 connected to rope 24. When the floating plate 25 rises and falls due to buoyancy, it moves rope 24, thereby driving gear 231 to rotate.

[0036] Furthermore, the bottom of the movable plate 232 is provided with a rack 2322 that meshes with the gear 231, and the transmitting probe 234 is set on the fixed cover 22 through the guide bar 233. The direction of the guide bar 233 is perpendicular to the rack 232 in the same horizontal plane, and the transmitting probe 234 and the guide bar 233 are slidably connected. When the gear 231 drives the movable plate 232 to move, the inclined guide groove 2321 will guide the transmitting probe 234 to move, and the direction of movement of the transmitting probe 234 is perpendicular to the direction of movement of the movable plate 232 under the restriction of the guide bar 233.

[0037] Furthermore, the mounting frame 1 is equipped with an information display screen 11, which is connected to the receiving screen 235. When the transmitting probe 234 moves, it sends a signal to the receiving screen 235, which is then displayed and recorded through the information display screen 11. The information display screen 11 is equipped with a storage module for receiving and storing the information on the receiving screen 235.

[0038] In the above technical solution, the water pipe 212 on the measuring cylinder 21 keeps the inside of the measuring cylinder 21 connected to the river water flow. Under the siphon principle, the float 25 is at the same height as the river water level in the measuring cylinder 21. When the water level rises or falls, the float 25 rises or falls accordingly. At this time, the limiter 251 drives the rope 24 to move, which in turn drives the gear 231 to rotate with the rotating wheel 241. Finally, the rack 232 moves the movable plate 232. When the movable plate 232 moves, the inclined guide groove 2321 changes position, and then guides the transmitting probe 234 to slide on the guide bar 233 and sends the signal to the receiving screen 235. Finally, the signal is recorded and displayed on the information display screen 11. This method can effectively monitor and record the river water level, making it easy to find changes in the river water level.

[0039] In addition, it includes a warning component 26 that is movably mounted on the floating plate 25, and a spring-shaped guide groove 2101 is provided inside the measuring cylinder 21. The warning component 26 includes a buzzer 261 that is rotatably mounted on the floating plate 25, and a guide block 262 that extends into the spring-shaped guide groove 2101 is provided on the side of the buzzer 261. When the water level in the river rises rapidly, the floating plate 25 pushes the buzzer 261 up and, in conjunction with the spring-shaped guide groove 2101, drives the buzzer 261 to rotate rapidly.

[0040] The buzzer 261 contains a power supply 263 and electrode plates 265 that are electrically connected to the positive and negative terminals of the power supply 263. A conductive strip 264 is elastically installed inside the buzzer 261, and a conductive plate is provided on the side of the conductive strip 264 near the center of the buzzer 261. There are two sets of conductive strips 264 symmetrically distributed on the buzzer 261. When the buzzer 261 rotates rapidly, the two sets of conductive strips 264 are forced to move away from each other due to centrifugal force, that is, the two sets of conductive strips 264 move away from each other and connect to the power supply 263, thereby powering the buzzer 261 and sounding the alarm.

[0041] In addition, the conductive strip 264 and the buzzer 261 are slidably connected, and the sliding direction of the conductive strip 264 is towards the center of the buzzer 261 and away from the center of the buzzer 261. An elastic element is provided between the conductive strip 264 and the buzzer 261. The elastic element is used to always push the conductive strip 264 towards the center of the buzzer 261, that is, in the initial state, the conductive sheet on the conductive strip 264 does not contact the electrode sheet 265.

[0042] It is worth noting that a loudspeaker cover 211 is provided between the top of the measuring cylinder 21 and the fixed cover 22. The loudspeaker cover 211 is used to amplify the sound emitted by the buzzer 261.

[0043] In the above technical solution, when the water level in the river rises rapidly, the float 25 will push the warning component 26 to rise rapidly. At this time, the guide block 262 on the buzzer 261 will cooperate with the spring-shaped guide groove 2101 in the measuring cylinder 21, so that the warning component 26 will rotate when it rises rapidly. Then, under the action of centrifugal force, the two sets of conductive strips 264 will be thrown to one side of the inner wall of the measuring cylinder 21. At this time, the conductive sheet set on the conductive strip 264 will contact the electrode sheet 265, thereby connecting the power supply 263 and the buzzer 261. At this time, the buzzer 261 will sound to give an early warning. At the same time, the loudspeaker cover 211 can amplify the sound of the buzzer 261 to improve the warning effect.

[0044] Working principle: First, the fixing frame 1 is set up on the riverbank. Then, the measuring cylinder 21 is placed in the river. The water pipe 212 on the measuring cylinder 21 keeps the inside of the measuring cylinder 21 connected to the river flow. The inlet of the water pipe 212 faces the same direction as the river flow and towards the downstream direction, preventing debris in the water from entering the measuring cylinder 21. Under the siphon principle, the float 25 is at the same height as the river water level when the water level rises or falls. At this time, the limiter 251 drives the rope 24 to move, which in turn drives the gear 231 to rotate, and finally, the rack 232 moves the movable plate 232. When the movable plate 232 moves, the inclined guide groove 2321 changes position, guiding the transmitting probe 234 to slide on the guide bar 233 and transmitting the signal. The signal is sent to the receiving screen 235 and finally recorded and displayed on the information display screen 11. It can effectively monitor and record the river water level, making it easy to find changes in the river water level. When the water level in the river rises rapidly, the float 25 will push the warning component 26 to rise rapidly. At this time, the guide block 262 on the buzzer 261 will cooperate with the spring-shaped guide groove 2101 in the measuring cylinder 21, so that the warning component 26 will rotate when it rises rapidly. Then, under the action of centrifugal force, the two sets of conductive strips 264 will be thrown to one side of the inner wall of the measuring cylinder 21. At this time, the conductive sheet set on the conductive strip 264 will contact the electrode sheet 265, thereby connecting the power supply 263 and the buzzer 261. At this time, the buzzer 261 will sound to give an early warning. At the same time, the loudspeaker cover 211 can amplify the sound of the buzzer 261 to improve the warning effect.

Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
