Description

Technical Field

[0001] This utility model relates to the field of water level monitoring devices, and in particular to water level flood control monitoring devices. Background Technology

[0002] Flood level monitoring devices are equipment systems that use mechanical, electronic, or sensor technologies to monitor and transmit data on changes in water levels in rivers, lakes, reservoirs, and urban flooding points in real time. These devices cover contact, non-contact, and integrated systems. Using these devices, water level dynamics can be captured in real time to provide early warnings, reduce disaster losses, provide a basis for the scientific allocation of flood control resources, and replace manual inspections, improving efficiency and safety. At the same time, they accumulate data to support long-term flood control decisions, making them a key tool for achieving proactive early warning and scientific flood control.

[0003] Existing flood control water level monitoring devices are divided into contact and non-contact types. Among the contact types, float-type water level gauges use buoyancy to make the float rise and fall with the water level, and convert the displacement into an electrical signal through mechanical transmission. Submersible level gauges calculate the water level by measuring pressure with a pressure sensor based on the relationship between liquid pressure and depth. Bubble-type water level gauges calculate the water level by measuring the air pressure value when the air pressure in the air tube is balanced with the water pressure. In the non-contact type, radar water level gauges and ultrasonic water level gauges emit electromagnetic waves and ultrasonic waves respectively, and calculate the water level by using the time difference of the reflected signals. Video image recognition systems identify the water level by recognizing the position of scales or reference objects in the image. These devices often integrate transmission, power supply and control units to realize data uploading and early warning closed loop.

[0004] However, current flood control water level monitoring devices have a significant limitation in practical applications: the probe angles are mostly fixed, making it difficult to adapt to different water surface conditions. For example, the water surface in the rapids of a river often presents a sloping wave shape, while the still water area of ​​a reservoir is a horizontal mirror surface. In urban flooding areas, the impact of drainage outlets can create vortex-like water surfaces. When facing such complex water surfaces, fixed-angle probes are prone to measurement errors due to deviations in signal reflection angles. In rapids, wave reflection signals are scattered, and in still water areas, strong light can create blind spots in mirror reflection. Vortexes can cause the signal focusing point to shift. This lack of angle adaptability directly affects data accuracy, limits the practical value of the device in diverse hydrological environments, and increases the cost and lag of manual adjustments. Summary of the Invention

[0005] To overcome the above shortcomings, this utility model provides a water level flood control monitoring device, which aims to improve the problem in the prior art that different angle probes are needed for different water surface conditions during equipment use.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] Reference Figures 1-3 This utility model provides an embodiment of a water level flood control monitoring device, including a support rod 1. A power distribution box 2 is installed on the outer wall of the support rod 1, which serves as a power hub to provide power to the monitoring component and the detection component. Multiple connecting rods 3 are fixedly connected to the top of the support rod 1 for connecting the monitoring component and the detection component. One end of one connecting rod 3 is equipped with a monitoring component for monitoring the water surface and the surrounding area. One end of another connecting rod 3 is fixedly connected with a connecting block 8 for connecting a detection component. Multiple positioning components are installed inside the connecting block 8 for fixing the angle of the detection component. A rotating shaft 9 is rotatably connected inside the connecting block 8 to provide mechanical support for the rotation of the monitoring component. Rotating bars 10 are fixedly connected to both ends of the rotating shaft 9 for driving the rotating shaft 9 to rotate. A monitoring component is installed on the outer wall of the rotating shaft 9 for monitoring the water surface conditions.

[0034] Each positioning component includes a ratchet 14, an actuating bar 15, and a fixing tooth 16. The inner wall of the ratchet 14 is fixedly connected to the outer wall of the rotating shaft 9 to limit the angle of the rotating shaft 9. The outer wall of the actuating bar 15 is slidably connected to the inside of the connecting block 8 to move the fixing tooth 16. One side of the fixing tooth 16 is fixedly connected to the bottom end of the actuating bar 15 to fix the ratchet 14. A rotating shaft 17 is fixedly connected inside the actuating bar 15 to provide mechanical support for the rotation of the actuating bar 15. A spring 18 is provided on one side of the actuating bar 15 to provide elastic force to the actuating bar 15. One end of the spring 18 is fixedly connected to one side of the actuating bar 15, and the other end of the spring 18 is fixedly connected to the inside of the connecting block 8. The monitoring component includes a solar panel 4, a mounting plate 5, and a camera 6. The bottom of the solar panel 4 is fixed. Connected to the top of the support rod 1, it is used to absorb solar energy to generate electricity. The outer wall of the fixed plate 5 is fixedly connected to one end of one of the connecting rods 3 for fixing the camera 6. The top of the camera 6 is fixedly connected to the bottom of the fixed plate 5 for monitoring the surrounding area and the water surface. The outer wall of the other connecting rod 3 is fixedly connected to a rain gauge 7 for collecting rainfall to monitor the rainfall. The monitoring components include a rotating block 11, a level gauge 12, and a probe 13. The inner wall of the rotating block 11 is fixedly connected to the outer wall of the rotating shaft 9 for connecting the level gauge 12 and the probe 13. The bottom of the level gauge 12 is fixedly connected to the top of the rotating block 11 for displaying the data detected by the probe 13. The top of the probe 13 is fixedly connected to the bottom of the rotating block 11 for detecting the water surface.

[0035] Specifically, when it is necessary to adjust the angle of the probe 13 to adapt to different water surface conditions, firstly, hold the lever 15 and pull it toward the level gauge 12. At this time, the fixed tooth 16 connected to the lever 15 will smoothly disengage from the tooth groove of the ratchet 14, releasing the lock on the angle of the probe 13. Next, hold the rotating bar 10 and use the smooth rotating shaft 9 to slowly rotate the probe 13 to the required angle. After the angle is calibrated, release the lever 15, and the built-in spring 18 will quickly rebound, pushing the fixed tooth 16 into the corresponding tooth groove of the ratchet 14, thus completing the firm locking of the angle of the probe 13, ensuring that it maintains a stable measurement angle under water flow impact or strong wind environment, and ensuring the accuracy of data acquisition.

[0036] Reference Figure 4 and Figure 5The distribution box 2 has a sliding groove 19 inside to accommodate sliding blocks 20. Multiple sliding blocks 20 are slidably connected inside the distribution box 2 to move fixed ring 1 24 and fixed ring 25. Multiple sliding posts 21 are fixedly connected to both sides of each sliding block 20 to limit its movement. A mating block 22 is fixedly connected to one side of each sliding block 20 to connect two sliding blocks 20. A mating groove 23 is opened on one side of each sliding block 20 to accommodate the mating block 22. The outer wall of each mating block 22 is slidably connected inside the mating groove 23. One of the sliding blocks 20 has a fixed ring 1 24 fixedly connected to one side to facilitate the movement of the distribution box. The electrical box 2 is fixed on the support rod 1. Another sliding block 20 has a fixed ring 25 fixedly connected to one side to fix the electrical box 2 on the support rod 1. The fixed ring 24 and the fixed ring 25 are both slidably connected to the insertion pin 26 to connect the fixed ring 24 and the fixed ring 25. Each insertion pin 26 has a moving strip 27 fixedly connected to one side to drive the insertion pin 26 to move. Each fixed ring 24 and the fixed ring 25 has a rotating column 28 rotatably connected to one side to provide mechanical support for the rotation of the fixing plate 29. Each rotating column 28 has a fixing plate 29 fixedly connected to the outer wall to fix the fixed ring 24 and the fixed ring 25 together.

[0037] Specifically, when installing the distribution box 2, firstly, hold the first fixing ring 24 and the second fixing ring 25 with both hands and slide them smoothly inward along the direction of the support rod 1. At this time, the sliding block 20 connected to the fixing ring will move synchronously until the mating block 22 between the sliding blocks 20 is embedded in the corresponding mating groove 23, forming a preliminary splicing and fixing. Next, hold the two moving strips 27 and pull them outward with a little force, causing the insertion pin 26 to slide along the preset track. Finally, the insertion pin 26 will pass into the inside of the first fixing ring 24 and the second fixing ring 25 respectively, further reinforcing the splicing structure. Finally, pull the fixing plate 29 upward so that the slot at its end catches the outer wall of the moving strip 27, completing the rigid fixing of the moving strip 27. The whole process can be done without the help of additional tools, so that the distribution box 2 can be firmly installed on the support rod 1, and good connection stability can be maintained even in outdoor wind and rain environments.

[0038] Working principle: When installing the distribution box 2 during the use of the water level flood control monitoring device, first hold the first fixing ring 24 and the second fixing ring 25 and slide them inward so that the mating block 22 between the sliding blocks 20 is inserted into the mating groove 23. Then hold the two moving strips 27 and pull them outward so that the insertion pins 26 are inserted into the first fixing ring 24 and the second fixing ring 25 respectively. Then move the fixing plate 29 to fix the moving strips 27, thereby installing the distribution box 2 on the support rod 1. When it is necessary to adjust the angle of the probe 13, first hold the lever 15 and pull it towards the liquid level gauge 12 so that the fixing tooth 16 is disengaged from the ratchet 14. Then hold the rotating bar 10 and use the rotating shaft 9 to adjust the angle of the probe 13 to the required angle. After the angle adjustment is completed, release the lever 15 so that the fixing tooth 16 rebounds into the ratchet 14 under the action of the spring 18, thereby fixing the angle of the probe 13.
