[0039] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0040] Please refer to Figures 1 to 8 , the present invention provides a technical solution: a water conservancy flood control monitoring system, including a vertical frame arranged on a river and a floating plate 13 thereon that rises and falls along with the water level line. The vertical frame is provided with a data analysis module remotely and electrically connected to a terminal module. The top of the vertical frame is provided with a photovoltaic panel and a storage battery for supplying power to multiple groups of modules. The vertical frame is provided with an early warning structure for detecting the height of the water level line and predicting the rising degree of the water level line;

[0041] The early warning structure includes a rectangular support plate 23 fixedly connected to the vertical frame. The floating plate 13 is provided with a pressing plate 25 that rises and falls synchronously with it at a position corresponding to the rectangular support plate 23. The pressing plate 25 is located below the rectangular support plate 23. A pressure sensor 24 is fixedly connected to one side of the rectangular support plate 23 facing the pressing plate 25. The pressure sensor 24 is electrically connected to the data analysis module;

[0042] A rain storage frame 1 for receiving rainwater is arranged at the top of the vertical frame. A water discharge hole 29 is opened at the bottom of the rain storage frame 1. Below the rain storage frame 1, there is an upper power connection copper sheet 21 that controls the horizontal height according to the rainwater volume in it and the horizontal position of the floating plate 13. A lower power connection copper sheet 22 is fixedly connected to the rectangular support plate 23 at a position corresponding to the upper power connection copper sheet 21;

[0043] Both the upper power connection copper sheet 21 and the lower power connection copper sheet 22 are electrically connected to the storage battery. The lower power connection copper sheet 22 is electrically connected to an alarm. The alarm is fixedly connected to the vertical frame and is electrically connected to the data analysis module;

[0044] The upper power connection copper sheet 21, the lower power connection copper sheet 22 and the alarm are electrically connected in series.

[0045] A vertical sliding groove for the vertical sliding of the floating plate 13 is opened on the vertical frame. A stretching column 27 is fixedly connected to the bottom of the floating plate 13. One end of the stretching column 27 away from the floating plate 13 is fixedly connected to a floating bladder 28 floating on the river surface. The vertical frame is provided with a co-location sliding seat 4 and a longitudinal moving component that drives the co-location sliding seat 4 to move in the vertical direction according to the weight of the rainwater in the rain storage frame 1. The upper power connection copper sheet 21 is fixedly connected to the co-location sliding seat 4.

[0046] As Figures 1 - 3As shown, the vertical frames are fixedly arranged on both sides of the riverbed or river channel. Among them, the floating bladder 28 floats above the river water level line and can move vertically with the rise and fall of the river water level. The floating bladder 28 and the floating board 13 are fixedly connected by the extending column 27. When the river water level line rises or falls, the floating board 13 can be driven by the floating bladder 28 to move up and down on the vertical frames.

[0047] Meanwhile, a pressure-receiving plate 25 that moves synchronously with the floating board 13 is provided on the floating board 13, and a pressure sensor 24 corresponding to the pressure-receiving plate 25 is provided on the vertical frame. When the river water level line rises, as the floating board 13 moves upward, the distance between the pressure-receiving plate 25 and the pressure sensor 24 gradually decreases. After the water level line reaches the first set value, the pressure-receiving plate 25 contacts the pressure sensor 24 and can apply pressure to it. At the same time, if the river water level line further rises, the floating board 13 continues to rise driven by the floating bladder 28, but the pressure-receiving plate 25 cannot move upward due to the obstruction of the pressure sensor 24. At this time, as the floating board 13 continues to rise, the pressure value received by the pressure sensor 24 will gradually increase.

[0048] Among them, the pressure sensor 24 is electrically connected to the data analysis module. The pressure sensor 24 transmits the received pressure signal to the data analysis module. The data analysis module processes the received signal and remotely transmits the processed signal to the terminal module. It should be noted that when the pressure-receiving plate 25 just contacts the pressure sensor 24, at this time, it represents that the water level line has reached the first warning position. At this time, the data analysis module processes the pressure signal and remotely transmits the primary warning signal to the terminal module. When the pressure received by the pressure sensor 24 reaches the set value, at this time, it represents that the water level line has reached the second or third warning position. The data analysis module processes the pressure signal and remotely transmits the warning signal of the corresponding level to the terminal module.

[0049] Meanwhile, an upper power connection copper sheet 21 that jointly controls the horizontal height according to the rainwater volume in the rain storage frame 1 and the horizontal position of the floating board 13 is provided on the vertical frame. A water discharge hole 29 is opened on the rain storage frame 1. When it is rainy, rainwater falls into it through the open end at the top of the rain storage frame 1. However, due to the existence of the water discharge hole 29, the rainwater inside it will naturally flow out of the rain storage frame 1 under the action of gravity. However, when the rainfall is large, the amount of rainwater flowing out of the rain storage frame 1 is less than the amount of rainwater accumulating. At this time, the mass of the rainwater in the rain storage frame 1 becomes larger and larger, and thus can drive the upper power connection copper sheet 21 to move downward.

[0050] It should be noted that when the river water level line is low, that is, when the pressure plate 25 is not in contact with the pressure sensor 24, the existence of the floating plate 13 will limit the horizontal height of the upper power connection copper sheet 21. At this time, when the water level line is low, no matter whether the rainfall is too large or not, the upper power connection copper sheet 21 can never be in contact with the lower power connection copper sheet 22, that is, the alarm cannot be in an alarm state at this time.

[0051] At the same time, when the river water level line is at the first-level warning position, that is, when the pressure plate 25 has been in contact with the pressure sensor 24, the floating plate 13 will no longer limit the vertical movement process of the upper power connection copper sheet 21. However, when the rainfall is small, the accumulation amount of rainwater in the rain storage frame 1 is less than the escape amount. Therefore, the upper power connection copper sheet 21 will not fall to the position of the lower power connection copper sheet 22, and thus the alarm will still not be in an alarm state at this time.

[0052] However, when the river water level line is at the first-level warning position and the rainfall is large, at this time, the accumulation amount of rainwater in the rain storage frame 1 is greater than the escape amount. The upper power connection copper sheet 21 moves downward under the action of the gravity of the rainwater and finally comes into contact with the lower power connection copper sheet 22, causing the circuit where the alarm is located to be unobstructed and in an alarm state. At this time, it means that the river water level line has reached the first-level warning position and its water level growth rate may be too fast due to rainfall factors. The alarm transmits the alarm signal to the signal analysis module. The signal analysis module combines the received alarm signal and pressure signal, and transmits the signals of the water level line height and the water level line rising speed to the terminal module to remind the terminal module to prevent this phenomenon.

[0053] Among them, after the data analysis module receives the electrical signal from the pressure sensor 24, it processes and analyzes the signal, specifically including:

[0054] Signal filtering: Remove noise and interference signals to ensure the accuracy of the data.

[0055] Signal amplification: Enhance the signal strength so that weak signals can be effectively recognized.

[0056] Data calibration: Calibrate the signal according to the preset calibration data to ensure the accuracy of the measurement results.

[0057] Threshold judgment: According to the preset water level warning threshold, judge whether the current water level reaches or exceeds the warning line. Different pressure values correspond to the first-level warning line, the second-level warning line, and the third-level warning line.

[0058] When the pressure detected by the pressure sensor 24 reaches the preset warning value, the data analysis module generates a corresponding warning signal and sends the warning signal to the remote terminal module by means such as radio or mobile network. The terminal module can be a computer, a mobile device or other receiving devices in the monitoring center. After receiving the warning signal, the terminal module performs corresponding processing and display, displays the current water level, warning level and real-time data chart on the terminal interface. When a higher warning signal is reached, the terminal module triggers an audible or visual alarm to remind the monitoring personnel to take corresponding measures.

[0059] In one relatively preferred embodiment, the longitudinal movement assembly includes a base 2 fixedly connected to the inner wall of the vertical frame. A vertical sliding seat 3 is provided on the base 2 and a first groove for its vertical sliding is formed. The vertical sliding seat 3 is fixedly connected to the rain storage frame 1.

[0060] A co-position sliding seat 4 that moves vertically synchronously with the vertical sliding seat 3 is provided on the vertical sliding seat 3. A limiting component for limiting the movement of the co-position sliding seat 4 is provided on the base 2. A second groove for the co-position sliding seat 4 to vertically slide is formed on the vertical sliding seat 3.

[0061] An end resistance block 5 is fixedly connected to the vertical sliding seat 3. A guiding pin 6 is fixedly connected to the side of the co-position sliding seat 4 facing the end resistance block 5. A round hole for the guiding pin 6 to slide through is formed on the end resistance block 5. A co-position spring 7 is sleeved on the outer peripheral surface of the guiding pin 6. The two ends of the co-position spring 7 are respectively fixedly connected to the end resistance block 5 and the co-position sliding seat 4.

[0062] A reset spring is provided on the vertical sliding seat 3. The two ends of the reset spring are respectively fixedly connected to the vertical sliding seat 3 and the vertical frame.

[0063] A rectangular groove for the pressure-receiving plate 25 to slide in the vertical direction is formed on the floating plate 13. A pressure-receiving spring 26 is provided on the pressure-receiving plate 25. The two ends of the pressure-receiving spring 26 are respectively fixedly connected to the pressure-receiving plate 25 and the floating plate 13.

[0064] As Figures 2 - 4 shown, when the accumulation amount of rainwater in the rain storage frame 1 is greater than the escape amount, the vertical sliding seat 3 is driven to move downward under the action of the gravity of the rainwater, and then the reset spring is driven to undergo a compressive deformation. At this time, under the action of the elastic potential energy of the co-position spring 7, the co-position sliding seat 4 is driven to move synchronously with the vertical sliding seat 3, and then the upper power connection copper sheet 21 fixedly arranged below the co-position sliding seat 4 is driven to approach the lower power connection copper sheet 22.

[0065] It should be noted that a pressing spring 26 is provided between the floating plate 13 and the pressing plate 25. When the water level line in the river rises and drives the floating plate 13 to move upward, under the action of the elastic potential energy of the pressing spring 26, the pressing plate 25 and the floating plate 13 rise synchronously. However, when the pressing plate 25 contacts the pressure sensor 24, the pressing plate 25 cannot continue to move upward. At this time, as the water level line continues to rise, the pressing spring 26 undergoes a compressive deformation, and the pressure exerted by the pressing plate 25 on the pressure sensor 24 gradually increases. Therefore, the pressure value received by the pressure sensor 24 is proportional to the height of the water level line. The data analysis module processes the strength of the pressure signal and then remotely transmits the processed signal result to the terminal module.

[0066] Based on the embodiment of the longitudinal movement assembly, the limiting assembly includes a side vertical rod 12 fixedly connected to the base 2. A transverse shaft 10 is rotatably fixed on the side vertical rod 12. A swing rod 9 is fixedly connected to the transverse shaft 10. One side surface of the swing rod 9 facing the same-position sliding seat 4 includes an integrally formed triangular portion 901.

[0067] A pointed corner block 8 is fixedly connected to the same-position sliding seat 4 corresponding to the position of the triangular portion 901.

[0068] A positioning assembly for restricting the rotation of the transverse shaft 10 is provided on the floating plate 13.

[0069] As Figure 2 、 Figure 3 、 Figure 4 and Figure 8 shown, when the same-position sliding seat 4 and the vertical sliding seat 3 move downward synchronously, the pointed corner block 8 provided on the same-position sliding seat 4 abuts against the triangular portion 901 and cannot continue to move downward. At this time, the same-position spring 7 undergoes a compressive deformation as the vertical sliding seat 3 continues to move. When the positioning assembly does not restrict the rotation of the transverse shaft 10, as the vertical sliding seat 3 continues to descend, the end resistance block 5 contacts the swing rod 9. At this time, under the obstruction of the end resistance block 5, the swing rod 9 and the transverse shaft 10 deflect, and then the same-position spring 7 resumes deformation and drives the same-position sliding seat 4 to move downward until the upper power connection copper sheet 21 and the lower power connection copper sheet 22 contact.

[0070] It should be noted that the positioning assembly will not restrict the rotation of the transverse shaft 10 only when the water level line is at the first-level warning position or a higher-level warning position. If the water level line is lower than the first-level warning position, under the restriction of the positioning assembly, the swing rod 9 will not be able to deflect, and thus the upper power connection copper sheet 21 will never be able to contact the lower power connection copper sheet 22, so that the alarm cannot be in an alarm state.

[0071] Among them, the prerequisite for the vertical sliding seat 3 to move downward is that the accumulation amount of rainwater in the rain storage frame 1 is greater than the escape amount. However, the prerequisite for whether the positioning component will restrict the transverse axis 10 is whether the water level line is at the first-level warning position or a higher-level warning position. Therefore, when the water level line is low, the positioning component restricts the transverse axis 10. At this time, no matter how much the rainfall is, the alarm cannot be triggered. After the water level line reaches the first-level warning position or a higher-level warning position, the pressure sensor transmits the detected pressure signal to the data analysis module in real time. If the rainfall is too large, the alarm can be triggered. At this time, the river channel state is that the water level line has exceeded the first-level warning position and the subsequent upward speed of the water level line may be relatively fast. Therefore, when the alarm is in the alarm state, it means that the subsequent water level rising speed may be too fast.

[0072] On the basis of the embodiment of the limiting component, the positioning component includes a side swing rod 11 coaxially fixed at the end of the transverse axis 10. The floating plate 13 includes an integrally formed convex straight portion 131 and a concave straight portion 132 corresponding to the position of the side swing rod 11. The end of the side swing rod 11 away from the transverse axis 10 contacts the surface of the convex straight portion 131 in the initial state.

[0073] As Figure 4 and Figure 5 As shown, when the river channel water level line does not reach the first-level warning position, the side swing rod 11 contacts the convex straight portion 131. At this time, under the restriction of the convex straight portion 131, the side swing rod 11 cannot deflect, so as to achieve the purpose of restricting the rotation of the transverse axis 10.

[0074] At the same time, when the river channel water level line reaches the first-level warning position or a higher-level warning position, the position of the side swing rod 11 corresponds to the position of the concave straight portion 132. At this time, the swinging process of the side swing rod 11 is no longer hindered, and then it can deflect with the continuous descent of the vertical sliding seat 3. It should be noted that a torsion spring for driving the transverse axis 10 to return to the initial deflection position is provided on the side vertical rod 12. This torsion spring is an existing device and a technical means well known to those skilled in the art, so it is not shown in the figure.

[0075] Furthermore, the main function of the vertical frame in this article is to support and protect the components inside it. Considering that the design and structure of the vertical frame are conventional technologies in the field, and its specific shape and size will vary according to actual application requirements, it is not shown in the figure.

[0076] Furthermore, a sealing component for adjusting the opening area at the top of the rain storage frame 1.

[0077] The sealing component includes a sealing plate 30 arranged on the rain storage frame 1 and moving freely in the horizontal direction. One side of the rain storage frame 1 facing the sealing plate 30 includes an integrally formed convex portion. A horizontal sliding groove for the horizontal sliding of the convex portion is opened on the sealing plate 30;

[0078] The sealing assembly further comprises a vertical lever 15 arranged on the vertical frame, the middle part of the vertical lever 15 is fixedly rotated on the vertical frame, a connecting plate 14 is fixedly connected to the floating plate 13, a positioning pin 16 is fixedly connected to one end of the vertical lever 15 facing the connecting plate 14, and a positioning groove 17 for the positioning pin 16 to slide is provided on the connecting plate 14;

[0079] The positioning groove 17 includes an integrally formed top straight groove portion 171, a middle oblique groove portion 172 and a bottom straight groove portion 173;

[0080] The sealing plate 30 is fixedly connected with a U-shaped frame 18 , and one end of the vertical lever 15 facing the U-shaped frame 18 is fixedly connected with a yield pin 19 . The U-shaped frame 18 is provided with a yield groove 20 for the yield pin 19 to slide.

[0081] like Figure 1 , Figure 2 , Figure 4 , Figure 6 and Figure 7 As shown, when the water level of the river gradually rises and is at the first-level warning position or a higher-level warning position, the floating plate 13 drives the connecting plate 14 to move upward, so that the positioning pin 16 still passes through the top straight groove portion 171, the middle oblique groove portion 172 and the bottom straight groove portion 173. Among them, when the positioning pin 16 passes through the position of the middle oblique groove portion 172, the horizontal position of the positioning pin 16 changes, thereby driving the vertical lever 15 to swing in the vertical direction.

[0082] When one end of the vertical lever 15 where the locating pin 16 is located swings away from the floating plate 13, it drives one end of the vertical lever 15 where the yield pin 19 is located to swing toward the side of the rain storage frame 1. When the vertical lever 15 swings, the horizontal height of the yield pin 19 thereon will change. Therefore, a yield groove 20 is provided on the U-shaped frame 18 to avoid the existence of the U-shaped frame 18 causing motion interference in the swinging process of the vertical lever 15.

[0083] At the same time, when the positioning pin 16 is converted to correspond to the top straight groove portion 171 to correspond to the bottom straight groove portion 173, the U-shaped frame 18 can drive the sealing plate 30 to move horizontally, and the horizontal movement of the sealing plate 30 can reduce the opening area of the rain storage frame 1. The purpose is to avoid the accidental phenomenon that the amount of water accumulated in the rain storage frame 1 is greater than the amount of water escaping due to short-term concentrated rainfall or the impact of river water flow. By reducing the opening size of the rain storage frame 1, the area for receiving rainwater is reduced. If the amount of rainwater accumulated in the rain storage frame 1 is still greater than the amount of water escaping at this time, the amount of rainfall can be expressed more accurately.

[0084] Although embodiments of the present invention have been shown and described, it will be understood by those of ordinary skill in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
