[0017] Embodiment: A buoy - type water level monitoring and alarm device As Figures 1-4 shown, a buoy - type water level monitoring and alarm device, its specific structure includes: Base 10, support assembly 20, radar detection assembly 30, lifting mechanism 40, monitoring pipe 50, buoy detection assembly 60. A support assembly 20 is fixedly provided on the top surface of the base 10. A radar detection assembly 30 is provided on one side of the upper part of the support assembly 20. A monitoring pipe 50 is fixedly installed on one side of the support assembly 20. A buoy detection assembly 60 is slidably and fittingly installed in the monitoring pipe 50. A lifting mechanism 40 is provided on the upper part of the support assembly 20. The lifting mechanism 40 is connected to the buoy detection assembly 60; Among them, the support assembly 20 includes: Support rod 201, a support rod 201 is fixedly installed on the top surface of the base 10. A cross bar is fixedly installed on one side of the support rod (201). The outer end of the cross bar is fixedly connected to one side of the monitoring pipe 50; Extension rod 202, an extension rod 202 is fixedly installed on the upper part of one side of the support rod 201. A radar detection assembly 30 is fixedly provided on one side of the bottom of the extension rod 202 away from the support rod 201. A lifting mechanism 40 is provided in the middle of the extension rod 202. The above working principle: The overall structure of this float - type water - level monitoring and alarming device is built on the basis of the base 10. When in use, the lower part of the monitoring tube 50 extends into the water. During installation, at least the water surface should be located in the middle of the monitoring tube 50. The support rod 201 of the support assembly 20 is fixed on the top surface of the base 10 to provide overall structural support. The extension rod 202 is fixed on the upper part of one side of the support rod 201, and an acoustic - optical alarm is provided at the top of the support rod 201. The radar detection assembly 30 is installed on the side of the bottom of the extension rod 202 away from the support rod 201 for water - level monitoring from above. The monitoring tube 50 is fixed on one side of the support assembly 20. The buoy detection assembly 60 slides in the monitoring tube 50 and can float up and down according to the water - level change. The lifting mechanism 40 is arranged on the upper part of the support assembly 20 and is connected to the buoy detection assembly 60 to control the position of the buoy detection assembly 60. The overall structure is stable. The base 10 and the support assembly 20 provide a reliable installation foundation for each component, ensuring that the device can operate stably in various environments. Combining the two detection methods of the radar detection assembly 30 and the buoy detection assembly 60, the water level can be monitored from different angles, and multiple groups of data can be measured and summarized for analysis, improving the accuracy and reliability of water - level monitoring.

[0018] The radar detection assembly 30 includes: The control cabinet 301 is fixedly installed in the middle of the support rod 201, and a controller is provided inside the control cabinet 301; The solar power supply panel 302 is fixedly installed on one side of the support rod 201. The solar power supply panel 302 is electrically connected to the storage battery. The position of the storage battery can be installed according to the actual situation. The storage battery is used to supply power to the controller and the radar water - level detector 303 to ensure the normal operation of the device; The radar water - level detector 303 is fixedly installed on the side of the bottom of the extension rod 202 away from the support rod 201.

[0019] In the radar detection assembly 30, the controller in the control cabinet 301 is responsible for the overall control logic. The solar power supply panel 302 converts solar energy into electrical energy to charge the storage battery, and the storage battery then supplies power to the controller and the radar water - level detector 303 to ensure the normal operation of the device. The radar water - level detector 303 measures the water - level height by emitting and receiving radar waves. It uses solar power supply, which is energy - saving and environment - friendly, reduces the operation cost of the device, and at the same time reduces the dependence on external power sources, improving the applicability of the device. It can be used in remote areas without external power sources. The radar water - level detector 303 has the advantages of high measurement accuracy and fast response speed, and can accurately obtain the water - level height information in real time.

[0020] The controller includes: A microprocessor for executing a control program to control the parameters of the radar water level detector 303, receive the water level height information obtained by the radar water level detector 303, process and analyze the water level height data, and be able to issue a warning message through an audible and visual alarm; A memory connected to the microprocessor for storing water level height data, system parameters, and program codes; A communication interface connected to the microprocessor for transmitting the water level height data to an external device or a monitoring center. The communication interface includes a wired communication interface and a wireless communication interface.

[0021] The microprocessor in the controller executes a preset control program to control the parameters of the radar water level detector 303, such as the transmission frequency, reception sensitivity, etc. At the same time, the microprocessor receives the water level height information obtained by the radar water level detector 303 and performs processing and analysis, such as filtering, calculating the average value, etc. The memory is used to store the water level height data, system parameters, and program codes for convenient subsequent data query and analysis. The communication interface transmits the processed water level height data to an external device or a monitoring center to implement the functions of remote monitoring and alarm.

[0022] The buoy detection component 60 includes: A floating block 601, which is slidably fitted in the monitoring tube 50. The diameter of the floating block 601 is smaller than the inner diameter of the monitoring tube 50, and the floating block 601 is connected to the lifting mechanism 40; A metal ring 602, which is fixedly installed on the top surface of the floating block 601; Hall sensors 603, several Hall sensors 603 are fixedly installed on one side of the monitoring tube 50 and arranged in sequence from top to bottom. The Hall sensors 603 are electrically connected to the controller. A protective cover 604 is fixedly installed outside the monitoring tube 50, and the Hall sensors 603 are all located inside the protective cover 604. The controller encodes the Hall sensors 603 in sequence from top to bottom and sets a height value for each Hall sensor 603. The metal ring 602 follows the floating block 601.

[0023] In the buoy detection component 60, the floating block 601 floats up and down in the monitoring tube 50 with the change of water level. The metal ring 602 is fixed on the top surface of the floating block 601 and moves with the floating block 601. A number of Hall sensors 603 installed on one side of the monitoring tube 50 are electrically connected to the controller. When the metal ring 602 passes by the Hall sensor 603, the Hall sensor 603 generates a signal and transmits it to the controller. The controller determines the water level height according to the preset coding and height value. The protective cover 604 protects the Hall sensor 603 from external environmental interference. Through the cooperation of the floating block 601 and the Hall sensor 603, the buoy detection component 60 realizes the intuitive monitoring of the water level and has high precision.

[0024] The lifting mechanism 40 includes: A wire winding wheel 401 which is rotatably installed in the middle of the extension rod 202; A support frame 402 which is fixedly installed at the bottom of the extension rod 202; A stepping motor 403 which is fixedly installed on one side of the support frame 402. The stepping motor 403 is electrically connected to the storage battery and the controller; A first gear 404 which is fixedly installed on one side of the outer circumference of the wire winding wheel 401; A second gear 405 which is fixedly installed on the output shaft of the stepping motor 403. The second gear 405 meshes with the first gear 404; A traction rope 406 which is wound around the outer circumference of the wire winding wheel 401; A connecting rod 407 which is fixedly installed at one end of the traction rope 406; A counterweight 408 which is fixedly installed at the lower end of the connecting rod 407. The connecting rod 407 passes through the metal ring 602 and the floating block 601 in sequence, and the floating block 601 is slidably matched with the connecting rod 407.

[0025] After the controller obtains the water level information through the radar water level detector 303, it judges whether it is necessary to adjust the position of the buoy detection component 60 according to the preset logic to further accurately monitor the water level or perform specific operations. The stepping motor 403 starts to work under the precise control of the controller. The output shaft of the stepping motor 403 starts to rotate, driving the second gear 405 fixedly connected to it to rotate synchronously. Since the second gear 405 meshes with the first gear 404, the first gear 404 also rotates under the drive of the second gear 405, and then drives the wire winding wheel 401 to rotate; When the winding wheel 401 rotates, the towing rope 406 wound around its outer periphery will be retracted and released. When it is necessary to lower the buoy detection assembly 60, the towing rope 406 is gradually released, driving the connecting rod 407 and the counterweight 408 to move downward. As the connecting rod 407 moves downward, the floating block 601 is lowered into the water. At this time, a part of the connecting rod 407 will extend into the water. Due to its own buoyancy, the floating block 601 will float on the water surface and can float up and down with the dynamic change of the water level. When the water level rises, the floating block 601 floats upward, driving the connecting rod 407 to have an upward movement tendency relative to the monitoring tube 50 (actually, the floating block 601 slides upward in the monitoring tube 50 due to the structural limitation of the monitoring tube 50); when the water level drops, the floating block 601 drops accordingly. Through the contact and floating of the floating block 601 with the water surface and its cooperation with the Hall sensor 603, the dynamic detection of the water level can be realized and accurate water level information can be obtained. When it is necessary to lift the buoy detection assembly 60, the towing rope 406 is wound up, driving the connecting rod 407 and the counterweight 408 to move upward, so that the floating block 601 leaves the water surface; By precisely controlling the lowering and lifting positions of the floating block 601 through the stepper motor 403 and combining the characteristics of the floating block 601 floating with the water level, the dynamic change information of the water level can be obtained more accurately, improving the accuracy and real-time performance of water level monitoring. According to different water level conditions or monitoring requirements, the position of the floating block 601 in the water can be flexibly adjusted, enabling the device to adapt to various complex water level monitoring scenarios. For example, in waters such as rivers and lakes with large water level fluctuations, through the cooperation of the lifting mechanism 40, the buoy detection assembly 60 and the radar water level detector 303 can work together. The radar water level detector 303 provides macroscopic water level information, and the buoy detection assembly 60 conducts microscopic dynamic monitoring. The two monitoring methods complement each other, further enhancing the reliability and comprehensiveness of water level monitoring. The entire process is automatically controlled by the controller, reducing manual intervention, improving the monitoring efficiency and automation level, and reducing labor costs and operation errors.

[0026] The counterweight 408 is a conical structure with a larger upper part and a smaller lower part, and a number of uniformly distributed through holes 409 are opened around the top surface of the counterweight 408. The counterweight 408 is a conical structure with a larger upper part and a smaller lower part. The through holes 409 opened around its top surface can enable water to enter and drain smoothly when the counterweight 408 enters the water, reducing the resistance when the counterweight 408 enters the water, ensuring the stability of the counterweight 408 in the water, and at the same time ensuring the contact between the water inside the monitoring tube 50 and the floating block 601, enabling the floating block 601 to float on the water surface.

[0027] A support ring 605 is fixedly installed at the bottom of the floating block 601. The support ring 605 is sleeved outside the connecting rod 407 and is in sliding fit with it. The lower end of the support ring 605 abuts against the top of the counterweight block 408. The support ring 605 provides stable support for the floating block 601, ensures the normal sliding of the floating block 601 on the connecting rod 407, improves the reliability of the buoy detection assembly 60, and at the same time prevents the floating block 601 from blocking the through hole 409.

[0028] An anti - detachment baffle 70 is fixedly installed at the upper end of the connecting rod 407. The anti - detachment baffle 70 is fixedly installed at the upper end of the connecting rod 407, which can prevent components such as the floating block 601 from coming out of the connecting rod 407.
