Technical Field
[0001] This invention relates to the field of water and electricity detection and alarm technology, and in particular to a smart water conservancy leakage detection and early warning system. Background Technology
[0002] In water conservancy and water pipe engineering, some important pipelines need to be leak detected. Strengthening the real-time and accurate location of leaks in water conservancy projects is of great significance to ensuring the safe and reliable operation of the projects.
[0003] To address the limitation of existing equipment in detecting only a small area of pipeline, Chinese Patent Publication No. CN114777032B discloses an automatic alarm device for detecting water leakage in water conservancy and hydropower projects. This device includes a detection mechanism with multiple water collection tanks on one side. Each water collection tank has a filter screen fixedly installed on its upper part. The detection mechanism and the multiple water collection tanks are buried under a water supply pipeline. Connecting pipes connect the multiple water collection tanks. Each water collection tank has a sealing mechanism that controls the unobstructed flow of the connecting pipes. The detection mechanism includes: a protective box, which is fixedly connected to and communicates with the internal cavity of the water collection tanks; a water immersion sensor, installed inside the protective box and positioned on the portion of the connecting pipe within the protective box; and a controller, installed inside the water immersion sensor and electrically connected to it. The controller integrates an alarm mechanism capable of sending alarm signals to an external terminal. While this solves the existing technical problems, the following issues remain:
[0004] The process of detecting the specific location of the leak in this technical solution is quite cumbersome, so corresponding improvements have been made to address this issue. Summary of the Invention
[0005] Based on the technical problems existing in the prior art, this invention proposes a smart water conservancy leakage detection and early warning system.
[0006] This invention proposes a smart water conservancy leakage detection and early warning system, comprising a pre-buried pipe embedded beneath a water conservancy pipeline, a drainage device installed within the pre-buried pipe, drainage outlets at both ends of the pre-buried pipe, and multiple evenly distributed water inlets at the top of the pre-buried pipe, located at the connection points of two adjacent water conservancy pipelines. A mesh plate is fixed inside each water inlet. The drainage device includes multiple sets of partitions located on both sides of the water inlets, with a pair of guide posts inserted at the top of each partition. The two ends of the guide posts are fixed to the inner wall of the pre-buried pipe. A lifting assembly and multiple detection mechanisms are installed within the pre-buried pipe. The lifting assembly is used to lift all the partitions upwards. The water accumulated in the pre-buried pipe is drained. Multiple detection agencies are located below the water inlet to detect leaks in the water pipe. A set of baffles forms a water storage area below the corresponding water inlet. The detection agencies can then detect each water storage area individually, thus pinpointing the location of the leak and sending an alert to the terminal to remind staff to carry out repairs. Once the staff has repaired the leak, they can lift all the baffles upwards using the lifting assembly. This allows the accumulated water to be quickly drained from the drain outlets on both sides of the pre-buried pipe, preventing water from accumulating in the pre-buried pipe for a long time and causing false alarms from the detection agencies.
[0007] Preferably, the lifting assembly includes a motor fixed to the inner wall of the top of the pre-buried pipe. The motor output shaft is fixedly connected to a drive shaft. Multiple fixed rods are also fixed at intervals on the inner wall of the top of the pre-buried pipe. The drive shaft is rotatably connected between the multiple fixed rods. A driven shaft located between a set of partitions is rotatably connected to each fixed rod. Cams for lifting the partitions are fixedly sleeved at both ends of the driven shaft. Two synchronous pulleys are fixedly sleeved on the driven shaft. Multiple synchronous pulleys are fixedly sleeved on the drive shaft. A set of adjacent synchronous pulleys are connected by a synchronous belt. A controller is fixed to the inner wall of the top of one end of the pre-buried pipe. The terminal operator can send a drainage command to the motor through the controller. The motor output shaft will drive the drive shaft to rotate. The drive shaft will drive all the driven shafts to rotate through the cooperation of the synchronous pulleys and the synchronous belt. Then, the cams will lift the partitions upward to drain water.
[0008] Preferably, the detection mechanism includes a humidity acquisition module located between a set of partitions and fixed to the inner wall of one side of the pre-buried pipe. A dehumidification device is also installed inside the pre-buried pipe. When water accumulates in a certain water storage area, and the air humidity in this water storage area reaches the threshold set by the humidity acquisition module, the humidity acquisition module will send an early warning to the terminal through the controller. Considering that although some water remains in the pre-buried pipe after drainage, the inside of the pre-buried pipe is still very humid, which will affect the air humidity inside the pre-buried pipe and cause false alarms from the humidity acquisition module, the remaining water can be removed by the dehumidification device after drainage.
[0009] Preferably, the detection mechanism includes a liquid level sensor, which is fixed on the inner wall of one of the partitions in a set of partitions. When water accumulates in a certain water storage area, and the liquid level in this water storage area reaches the position of the liquid level sensor, the liquid level sensor will send an early warning to the terminal through the controller. After the water accumulated in the pre-buried pipe is drained, the humid environment inside the pre-buried pipe will not cause false alarms from the liquid level sensor, thus eliminating the need for dehumidification.
[0010] Preferably, the dehumidification device includes multiple electric heating tubes and an exhaust fan. The electric heating tubes are fixed on the inner wall of one side of the pre-embedded pipe, and the exhaust fan is fixed on the inner wall of the top of the pre-embedded pipe. The electric heating tubes and the exhaust fan are located between a set of partitions. When the electric heating tubes and the exhaust fan are turned on, the electric heating tubes can heat the air, and the exhaust fan can accelerate the discharge of moisture inside the pre-embedded pipe, thereby achieving the purpose of dehumidification.
[0011] Preferably, it further includes:
[0012] Multiple current acquisition modules are located between a set of partitions. The current acquisition modules are installed on the inner wall of one side of the pre-embedded pipe to obtain the actual output current of the heating element when it is working in real time, and generate the current change coefficient through the controller.
[0013] The humidity acquisition module is also used to acquire the air humidity in the water storage area in real time and generate a humidity change coefficient through the controller;
[0014] The controller performs a comprehensive analysis of the generated humidity change coefficient and current change coefficient to generate an evaluation coefficient. By comparing the evaluation coefficient with a pre-set evaluation coefficient reference threshold, it is determined whether the heating element needs to change its working mode, and the working state of the heating element is controlled according to the comparison result.
[0015] Preferably, the output terminal of the controller is electrically connected to the input terminals of the heating element and the exhaust fan, respectively, and the input and output terminals of the current acquisition module and the humidity acquisition module are electrically connected to the output and input terminals of the controller, respectively.
[0016] Preferably, the logic for obtaining the humidity variation coefficient is as follows:
[0017] S1. Obtain the actual air humidity in the water storage area at different times during the working time T of the electric heating element using the humidity acquisition module, and calibrate the actual air humidity in the water storage area at different times during the working time T of the electric heating element as... , where n represents the number of the actual air humidity in the water storage area at different times within time T when the electric heating element is working. , It is a positive integer;
[0018] S2. Calculate the humidity variation coefficient. The expression for the calculation is:
[0019] In the formula, This is the humidity variation coefficient.
[0020] Preferably, the logic for obtaining the current variation coefficient is as follows:
[0021] S1. Obtain the actual output current of the heating element at different times during the working time T using the current acquisition module, and calibrate the actual output current of the heating element at different times during the working time T as follows: , m represents the number of the actual output current of the heating element at different times within time T during operation. , It is a positive integer;
[0022] S2. Calculate the current variation coefficient. The expression for the calculation is:
[0023] In the formula, This is the coefficient of current variation.
[0024] Preferably, the analysis is performed using a formulaic approach by the controller, based on the following formula:
[0025] ;
[0026] In the formula, For evaluation coefficients, and These are the preset proportional coefficients for humidity change coefficient and current change coefficient, respectively. and All are greater than 0;
[0027] Set the pre-defined evaluation coefficient reference threshold to The controller compares the calculated evaluation coefficients with pre-set reference thresholds to determine whether the dehumidifier needs to change its operating mode. Based on the comparison results, it controls the operating status of the heating element and the exhaust fan. The specific determination is as follows:
[0028] when When the dehumidifier does not need to change its working mode, it generates a normal signal. After receiving the normal signal, the controller generates a hold signal and transmits the hold signal to the heating element and the exhaust fan respectively. After receiving the hold signal, the heating element and the exhaust fan control the dehumidifier to maintain the working mode.
[0029] when When the dehumidifier needs to change its operating mode, a potential hazard signal is generated. After receiving the potential hazard signal, the controller generates an adjustment signal and transmits the potential hazard signal to the heating element and the exhaust fan respectively. After receiving the potential hazard signal, the heating element and the exhaust fan control the dehumidifier to adjust its operating mode.

Detailed Implementation
[0044] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.
[0045] In the description of this invention, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.
[0046] Reference Figures 1-8 A smart water conservancy leakage detection and early warning system includes a pre-buried pipe 1 buried under a water conservancy pipeline. A drainage device is installed inside the pre-buried pipe 1. Drainage outlets 18 are opened at both ends of the pre-buried pipe 1. Multiple evenly distributed water inlets 2 are provided at the top of the pre-buried pipe 1. The water inlets 2 are located at the connection of two adjacent water conservancy pipelines. A mesh plate 3 is fixed inside the water inlet 2. The drainage device includes multiple sets of partitions 4 located on both sides of the water inlet 2. A pair of guide columns 5 are inserted at the top of the partitions 4. The two ends of the guide columns 5 are fixed to the inner wall of the pre-buried pipe 1. A lifting component and multiple detection mechanisms are installed inside the pre-buried pipe 1. The lifting component is used to lift all the partitions 4 upward to drain the water accumulated in the pre-buried pipe 1. The multiple detection mechanisms are located below the water inlets 2 and are used to detect leakage in the water conservancy pipeline.
[0047] It should be noted that a set of baffles 4 forms a water storage area below the corresponding water inlet 2. The testing agency can test each water storage area separately, so as to specifically determine the location of the water pipe leak and send an early warning to the terminal to remind the staff to carry out maintenance. After the staff has completed the maintenance of the leak location, they can lift all the baffles 4 upwards by lifting components. In this way, the accumulated water can be quickly discharged from the drain outlets 18 on both sides of the pre-buried pipe 1, thereby avoiding the long-term accumulation of water in the pre-buried pipe 1 and causing false alarms by the testing agency.
[0048] The lifting assembly includes a motor 6 fixed to the inner wall of the top of the pre-embedded pipe 1. The output shaft of the motor 6 is fixedly connected to a drive shaft 7. Multiple fixed rods 8 are also fixed at intervals on the inner wall of the top of the pre-embedded pipe 1. The drive shaft 7 is rotatably connected between the multiple fixed rods 8. A driven shaft 9 located between a set of partitions 4 is rotatably connected to the fixed rods 8. Cams 10 for lifting the partitions 4 are fixedly sleeved at both ends of the driven shaft 9. Two synchronous pulleys 11 are fixedly sleeved on the driven shaft 9. Multiple synchronous pulleys 11 are fixedly sleeved on the drive shaft 7. A set of adjacent synchronous pulleys 11 are connected by a synchronous belt 12. A controller 13 is fixedly installed on the inner wall of the top of one end of the pre-embedded pipe 1.
[0049] It should be noted that the terminal staff can send a drainage command to the motor 6 through the controller 13. The output shaft of the motor 6 will drive the drive shaft 7 to rotate. The drive shaft 7 will drive all the driven shafts 9 to rotate through the cooperation of the synchronous pulley 11 and the synchronous belt 12. Then, the cam 10 will push the partition 4 upward to drain the water.
[0050] In Example 1, the detection mechanism includes a humidity acquisition module 14, which is located between a set of partitions 4. The humidity acquisition module 14 is fixed on the inner wall of one side of the pre-embedded pipe 1, and a dehumidification device is also provided inside the pre-embedded pipe 1.
[0051] It should be noted that when water accumulates in a certain water storage area, if the air humidity in the water storage area reaches the threshold set by the humidity acquisition module 14, the humidity acquisition module 14 will send an alarm to the terminal through the controller 13. Considering that although there is still some water left in the pre-buried pipe 1 after drainage, the inside of the pre-buried pipe 1 is still very humid, which will affect the air humidity in the pre-buried pipe 1 and cause false alarms from the humidity acquisition module 14, the remaining water can be removed by a dehumidification device after drainage.
[0052] In embodiment 2, the detection mechanism includes a liquid level sensor 19, which is fixed on the inner wall of one of the partitions 4 in a set of partitions 4.
[0053] It should be noted that when water accumulates in a certain water storage area, and the liquid level in that water storage area reaches the position of the liquid level sensor 19, the liquid level sensor 19 will send an early warning to the terminal through the controller 13. After the water accumulated in the pre-buried pipe 1 is drained, the humid environment inside the pre-buried pipe 1 will not cause false alarms from the liquid level sensor 19, thus eliminating the need for dehumidification operation.
[0054] The dehumidification device includes multiple electric heating tubes 16 and exhaust fans 17. The electric heating tubes 16 are fixed on the inner wall of one side of the pre-embedded pipe 1, and the exhaust fans 17 are fixed on the inner wall of the top of the pre-embedded pipe 1. The electric heating tubes 16 and the exhaust fans 17 are located between a set of partitions 4.
[0055] It should be noted that when the heating element 16 and the exhaust fan 17 are turned on, the heating element 16 can heat the air, and the exhaust fan 17 can accelerate the discharge of moisture inside the pre-embedded pipe 1, thereby achieving the purpose of dehumidification.
[0056] Furthermore, it also includes:
[0057] Multiple current acquisition modules 15 are located between a set of partitions 4. The current acquisition modules 15 are installed on the inner wall of one side of the pre-embedded pipe 1 to acquire the actual output current of the heating tube 16 in real time when it is working, and generate the current change coefficient through the controller 13.
[0058] The humidity acquisition module 14 is also used to acquire the air humidity of the water storage area in real time and generate a humidity change coefficient through the controller 13;
[0059] The controller 13 performs a comprehensive analysis of the generated humidity change coefficient and current change coefficient to generate an evaluation coefficient. The evaluation coefficient is compared with a pre-set evaluation coefficient reference threshold to determine whether the heating element 16 needs to change its working mode, and the working state of the heating element 16 is controlled according to the comparison result.
[0060] The current acquisition module 15 can be a current sensor or other device that can acquire the actual output current in real time, and the humidity acquisition module 14 can be a humidity sensor or other device that can acquire the air humidity in real time. No specific limitation is made here.
[0061] Furthermore, the output terminal of the controller 13 is electrically connected to the input terminal of the heating element 16 and the exhaust fan 17, respectively, and the input and output terminals of the current acquisition module 15 and the humidity acquisition module 14 are electrically connected to the output and input terminals of the controller 13, respectively.
[0062] It should be noted that electrical connection refers to the process of transferring current from one part of an electronic device or circuit to another through conductive materials or conductive elements. This connection is a key component for the operation of electronic devices and circuits, ensuring the effective transmission and connection of electron flow in electronic devices. Electrical connections can be made using wires. The method of electrical connection in this solution is not specifically limited and can be selected according to actual needs.
[0063] In this embodiment, the humidity change coefficient is the difference between the actual humidity of the water storage area at the initial moment and the actual humidity of the water storage area at different times during the working time T of the heating element 16, as obtained by the humidity acquisition module 14. The larger the difference, the larger the humidity change coefficient, indicating that the working mode of the heating element 16 can meet the requirements of normal dehumidification; conversely, it indicates that the working mode of the heating element 16 does not meet the requirements of normal dehumidification.
[0064] The logic for obtaining the humidity variation coefficient is as follows:
[0065] S1. Obtain the actual air humidity of the water storage area at different times during the working time T of the electric heating tube 16 through the humidity acquisition module 14, and calibrate the actual air humidity of the water storage area at different times during the working time T of the electric heating tube 16 as... , where n represents the number of the actual air humidity in the water storage area at different times within time T during the operation of the electric heating element 16. , It is a positive integer;
[0066] S2. Calculate the humidity variation coefficient. The expression for the calculation is:
[0067] In the formula, This is the humidity variation coefficient.
[0068] The current variation coefficient is the difference between the actual output current of the heating element 16 at the initial moment and the actual output current at different moments during the working time T obtained by the acquisition module 15. The larger the difference, the larger the current variation coefficient, indicating that the air humidity changes greatly and that the working mode of the heating element 16 can meet the normal dehumidification. Conversely, the smaller the difference, the smaller the air humidity changes, indicating that the working mode of the heating element 16 does not meet the normal dehumidification.
[0069] Furthermore, the logic for obtaining the current variation coefficient is as follows:
[0070] S1. The actual output current of the heating element 16 at different times during the working time T is obtained through the current acquisition module 15, and the actual output current of the heating element 16 at different times during the working time T is calibrated as follows: , m represents the number of the actual output current of the heating element 16 at different times within time T during operation. , It is a positive integer;
[0071] S2. Calculate the current variation coefficient. The expression for the calculation is:
[0072] In the formula, This is the coefficient of current variation.
[0073] Furthermore, a formulaic analysis is performed using controller 13, based on the following formula:
[0074] ;
[0075] In the formula, For evaluation coefficients, and These are the preset proportional coefficients for humidity change coefficient and current change coefficient, respectively. and All are greater than 0;
[0076] The calculated expression shows that the humidity variation coefficient... The smaller the coefficient of variation of current, the better. The larger the value, the larger the evaluation coefficient.
[0077] Set the pre-defined evaluation coefficient reference threshold to The controller 13 compares the calculated evaluation coefficient with the preset evaluation coefficient reference threshold to determine whether the dehumidifier needs to change its working mode, and controls the working status of the heating element 16 and the exhaust fan 17 according to the comparison result. The specific determination is as follows:
[0078] when When the dehumidifier does not need to change its working mode, it generates a normal signal. After receiving the normal signal, the controller 13 generates a hold signal and transmits the hold signal to the heating element 16 and the exhaust fan 17 respectively. After receiving the hold signal, the heating element 16 and the exhaust fan 17 control the dehumidifier to maintain its working mode.
[0079] The "maintain working mode" means that after receiving the "maintain" signal, the heating element 16 and the exhaust fan 17 maintain their current continuous dehumidification power.
[0080] when When the dehumidifier needs to change its working mode, a hazard signal is generated. After receiving the hazard signal, the controller 13 generates an adjustment signal and transmits the hazard signal to the heating element 16 and the exhaust fan 17 respectively. After receiving the hazard signal, the heating element 16 and the exhaust fan 17 control the dehumidifier to adjust its working mode.
[0081] Adjusting the working mode: After receiving the adjustment signal, the electric heating element 16 and the exhaust fan 17 respectively change the current continuous dehumidification and switch to a higher power dehumidification state.
