Description

Technical Field

[0001] The invention relates to the technical field of water level measurement, and in particular to a water level measuring device for river channel monitoring. Background Art

[0002] Water level is the most intuitive factor reflecting the water conditions of water bodies. Its changes are mainly caused by the increase or decrease of water volume in water bodies. Water level monitoring is an indispensable part of water conservancy project monitoring work.

[0003] At present, water level gauges are commonly used to monitor river water levels. However, most traditional water level gauges have simple structures and require manual readings. The surface of the water level gauge is easily contaminated by pollutants, resulting in unclear readings and failure to provide timely feedback of water level information. For this reason, a Chinese patent discloses a water level monitoring device (authorization announcement number CN218238997U). The patent connects a floating plate and a sliding sleeve by sliding on the surface of a sliding rod. The floating plate floats under the buoyancy of the water flow, and the sliding sleeve slides on the surface of the scale. The scraper at the bottom of the floating plate slides on the surface of the scale as the water level changes, thereby removing attachments on the surface of the scale to prevent dirt in the water from adhering to the surface of the scale and causing unclear scale readings.

[0004] However, there are still some deficiencies in the above-mentioned public documents, which cannot reflect the 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 prior art, the present invention provides a water level measuring device for river monitoring, which can effectively solve the problems in the prior art that the real-time changes of the river water level cannot be recorded and the early warning capability is not provided.

[0006] To achieve the above objectives, the present invention is implemented through the following technical solutions: The present invention provides a water level measuring device for river channel monitoring, comprising a fixing frame and further comprising: A measuring assembly, the measuring assembly comprising a measuring tube arranged in a river channel and a floating plate movably installed in the measuring tube, a fixed cover is arranged on the top of the measuring tube, a rope connected to the floating plate is arranged on the measuring tube, and a water pipe is arranged at the bottom of the measuring tube; And a recording component, the recording component includes a gear rotatably set on the fixed cover and connected to the rope drive, a movable plate slidably connected to the fixed cover and connected to the gear drive, the movable plate is provided with an inclined guide groove, the fixed cover is slidably installed with a transmitting probe extending into the inclined guide groove, and the fixed cover is provided with a receiving screen located above the transmitting probe.

[0007] Furthermore, the rope is arranged on the measuring cylinder through multiple sets of rotating wheels, and the gear is coaxially arranged with the rotating wheel. A limiting piece connected to the rope is provided on the floating plate. When the floating plate rises or falls due to buoyancy, the rope is moved to drive the gear to rotate.

[0008] Furthermore, a rack meshing with the gear is provided at the bottom of the movable plate, and the transmitting probe is set on the fixed cover through a guide bar. The setting direction of the guide bar and the rack are perpendicular to each other 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 movement of the transmitting probe, and under the restriction of the guide bar, the moving direction of the transmitting probe is perpendicular to the moving direction of the movable plate.

[0009] Furthermore, an information display screen is provided on the fixing frame, and the information display screen is communicatively connected with the receiving screen. When the transmitting probe moves, the signal is sent to the receiving screen, which is then displayed and recorded through the information display screen.

[0010] Furthermore, a mounting seat is provided at the bottom of the measuring cylinder, and a spring-shaped guide groove is provided inside the measuring cylinder.

[0011] Furthermore, it also includes a warning component movably arranged on the floating plate, the warning component includes a buzzer rotatably arranged on the floating plate, and a guide block extending into a spring-shaped guide groove is provided on the side of the buzzer. When the water level in the river channel rises rapidly, the floating plate pushes the buzzer to rise and cooperates with the spring-shaped guide groove to drive the buzzer to rotate rapidly.

[0012] Furthermore, a power supply is provided inside the buzzer, and electrode sheets 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 sheet is provided on one side of the conductive strip close to the center of the buzzer.

[0013] Furthermore, the conductive strip and the buzzer are slidably connected, and the sliding direction of the conductive strip is toward the center of the buzzer and away from the center of the buzzer. An elastic member is provided between the conductive strip and the buzzer, and the elastic member is used to always push the conductive strip toward 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.

[0014] Furthermore, a sound amplification cover is provided between the top of the measuring tube and the fixed cover.

[0015] Beneficial Effects Compared with the known prior art, the technical solution provided by the present invention has the following beneficial effects: 1. The water pipe on the measuring tube is used to keep the inside of the measuring tube connected to the river water flow. Under the siphon principle, the height of the floating plate in the measuring tube is the same as the river water level. When the water level rises or falls, the floating plate rises and falls accordingly. At this time, the limiter drives the rope to move, and then the rotating wheel drives the gear to rotate, and finally the rack is used to move the movable plate. When the movable plate moves, the position changes, and then the transmitting probe is guided to slide on the guide bar, and the signal is sent to the receiving screen. Finally, it is recorded and displayed on the information display screen, which can well monitor the river water level and record the river water level, making it easy to find the river water level change; 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 in the measuring tube, causing the warning component to rotate during rapid rise. Then, under the action of centrifugal force, the two sets of conductive strips will be thrown to the side of the inner wall of the measuring tube. At this time, the conductive sheet set on the conductive strip will contact the electrode sheet, thereby connecting the power supply and the buzzer. At this time, the buzzer will sound for early warning. At the same time, the sound amplification cover can amplify the sound of the buzzer to improve the early warning effect.

[0020] The present invention will be further described below in conjunction with the embodiments.

A mounting seat 213 is arranged at the bottom of the measuring tube 21. The measuring tube 21 is connected to the fixing frame 1 through a bracket, and the measuring tube 21 is fixed with the mounting seat 213 to prevent the equipment from being unstable due to the impact of river water. A fixing cover 22 is arranged on the top of the measuring tube 21. The fixing cover 22 is used to prevent rainwater and debris from entering the measuring tube 21 and is also used as a support for the subsequent installation of components. A rope 24 connected to the floating plate 25 is arranged on the measuring tube 21 through a plurality of sets of rotating wheels 241. On the measuring cylinder 21, a 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 floating plate 25 rises or falls due to buoyancy, the rope 24 is driven to move on the rotating wheel 241. A water pipe 212 is provided at the bottom of the measuring cylinder 21. The water pipe 212 is used to keep the measuring cylinder 21 always connected with the water flow in the river channel, and the water inlet of the water pipe 212 is oriented in the same direction as the water flow in the river channel and toward the downstream direction of the river channel, which can prevent debris in the water flow from entering the measuring cylinder 21. Due to the provision of the water pipe 212, the water level in the measuring cylinder 21 will always be consistent with the water level in the river channel through the siphon principle. And a recording component 23, the recording component 23 is used to monitor the change of the water level in the river. The recording component 23 includes a gear 231 rotatably set on the fixed cover 22 and drivingly connected to the rope 24, a movable plate 232 slidably connected to the fixed cover 22 and drivingly connected to the gear 231, an inclined guide groove 2321 is provided on the movable plate 232, and a transmitting probe 234 extending into the inclined guide groove 2321 is slidably installed on the fixed cover 22. When the movable plate 232 moves, the transmitting probe 234 is guided to slide in the inclined guide groove 2321. The moving directions of the movable plate 232 are different, and the moving directions of the transmitting probe 234 are guided to be different to record the change of the water level in the river. A receiving screen 235 located above the transmitting probe 234 is provided on the fixed cover 22. When the transmitting probe 234 moves, information is sent to the receiving screen 235 to reflect the change of the water level in the river.

[0022] Specifically, the gear 231 is coaxially arranged with the rotating wheel 241. When the rotating wheel 241 is driven by the rope 24, it rotates. A limiting member 251 connected to the rope 24 is provided on the floating plate 25. When the floating plate 25 rises or falls due to buoyancy, the rope 24 is moved to drive the gear 231 to rotate.

[0023] Furthermore, a rack 2322 meshingly connected to the gear 231 is provided at the bottom of the movable plate 232, and the transmitting probe 234 is set on the fixed cover 22 through the guide bar 233. The setting direction of the guide bar 233 is perpendicular to the rack 2322 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 under the restriction of the guide bar 233, the moving direction of the transmitting probe 234 is perpendicular to the moving direction of the movable plate 232.

[0024] Furthermore, an information display screen 11 is provided on the fixed frame 1, and the information display screen 11 is communicatively connected with the receiving screen 235. When the transmitting probe 234 moves, the signal is sent to the receiving screen 235, which is then displayed and recorded through the information display screen 11. A storage module is provided inside the information display screen 11 for receiving and storing the information on the receiving screen 235.

[0025] In the above technical scheme, the water pipe 212 on the measuring tube 21 is used to keep the inside of the measuring tube 21 connected with the river water flow. Under the siphon principle, the height of the float 25 at the measuring tube 21 is the same as the river water level. When the water level rises or falls, the float 25 rises and falls accordingly. At this time, the limit member 251 drives the rope 24 to move, and then cooperates with the rotating wheel 241 to drive the gear 231 to rotate, and finally cooperates with the rack 2322 to move 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, and finally records and displays it through the information display screen 11, which can well monitor the river water level and record the river water level, making it easy to find the river water level change.

[0026] In addition, it also includes a warning component 26 movably arranged on the floating plate 25, and a spring-shaped guide groove 2101 is provided in the measuring tube 21. The warning component 26 includes a buzzer 261 rotatably arranged on the floating plate 25, and a guide block 262 extending into the spring-shaped guide groove 2101 is provided on the side of the buzzer 261. When the water level in the river channel rises rapidly, the floating plate 25 pushes the buzzer 261 to rise and cooperates with the spring-shaped guide groove 2101 to drive the buzzer 261 to rotate rapidly.

[0027] Among them, a power supply 263 is provided inside the buzzer 261, and an electrode sheet 265 is provided inside the buzzer 261 to electrically connect the positive and negative poles of the power supply 263 respectively. A conductive strip 264 is elastically installed inside the buzzer 261, and a conductive sheet is provided on the side of the conductive strip 264 close to the center of the buzzer 261. The conductive strip 264 is provided in two groups and is symmetrically distributed on the buzzer 261. When the buzzer 261 rotates rapidly, the two groups of conductive strips 264 are forced to send displacements due to centrifugal force, that is, the two groups of conductive strips 264 move away from each other and connect to the power supply 263, thereby supplying power to the buzzer 261 and sounding an early warning.

[0028] In addition, the conductive strip 264 and the buzzer 261 are slidably connected, and the sliding direction of the conductive strip 264 is toward the center of the buzzer 261 and away from the center of the buzzer 261. An elastic member is provided between the conductive strip 264 and the buzzer 261, and the elastic member is used to always push the conductive strip 264 toward the center of the buzzer 261, that is, in the initial state, the conductive sheet on the conductive strip 264 is not in contact with the electrode sheet 265.

[0029] It is worth noting that a sound amplifying cover 211 is provided between the top of the measuring tube 21 and the fixed cover 22, and the sound amplifying cover 211 is used to amplify the sound emitted by the buzzer 261. In the above technical solution, when the water level in the river channel 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 tube 21, so that the warning component 26 rotates when it rises rapidly, and then under the action of centrifugal force, the two groups of conductive strips 264 are thrown to the side of the inner wall of the measuring tube 21. At this time, the conductive sheet arranged on the conductive strip 264 contacts the electrode sheet 265, and then the power supply 263 and the buzzer 261 are connected. At this time, the buzzer 261 sounds for warning, and at the same time, the sound amplifier 211 can amplify the sound of the buzzer 261 to improve the warning effect.

[0030] Working principle: when in use, first set the fixing frame 1 on the bank of the river channel, then put the measuring tube 21 into the river channel, and keep the inside of the measuring tube 21 connected with the river water flow through the water pipe 212 on the measuring tube 21. The water inlet of the water pipe 212 faces the same direction as the river water flow and faces the downstream direction of the river channel, which can prevent debris in the water flow from entering the measuring tube 21. Under the siphon principle, the height of the floating plate 25 at the measuring tube 21 is the same as the river water level. When the water level rises or falls, the floating plate 25 rises and falls accordingly. At this time, the limiter 251 drives the rope 24 to move, and then the rotating wheel 241 drives the gear 231 to rotate, and finally the rack 2322 is used to move 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 transmits the signal The signal is sent to the receiving screen 235, and finally recorded and displayed through the information display screen 11, which can well monitor the water level of the river and record the water level of the river, so as to facilitate the search for changes in the water level of the river. 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 tube 21, so that the warning component 26 rotates when it rises rapidly, and then under the action of centrifugal force, the two groups of conductive strips 264 are thrown to the side of the inner wall of the measuring tube 21. At this time, the conductive sheet arranged on the conductive strip 264 contacts the electrode sheet 265, and then the power supply 263 and the buzzer 261 are connected. At this time, the buzzer 261 sounds for warning, and the sound amplifier 211 can amplify the sound of the buzzer 261 to improve the warning effect.
