Description

Technical Field

[0001] This utility model relates to the field of water level monitoring devices, specifically a water level monitoring device. Background Technology

[0002] Water level monitoring involves collecting water level data in real time using various sensors to enable remote monitoring and early warning of dynamic changes in water levels. It is widely used in flood control and drought relief, water resource management, urban waterlogging early warning, and water conservancy project monitoring, providing real-time data support for disaster prevention, water allocation, and emergency decision-making.

[0003] The water level monitoring process begins with equipment deployment. Sensors such as ultrasonic and radar are installed at appropriate locations in the water body and connected to the data acquisition terminal and power supply system. Then, water level data is collected in real time and transmitted wirelessly or via wired to the monitoring platform. The platform processes and calibrates the data before storing it in the database and displays the water level through a visual interface. When the water level exceeds a preset threshold, an alarm is triggered. Finally, the monitoring and analysis data provide decision-making basis for flood control, drought relief, and water resource allocation.

[0004] Most existing water level monitoring devices are electrically powered, which makes power traction cumbersome in remote areas and makes the installation of the monitoring equipment difficult. Therefore, a water level monitoring device is proposed to address the above problems. Utility Model Content

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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 scope of protection of the present utility model.

[0023] Specific implementation examples are given below.

[0024] like Figures 1 to 5 As shown in the embodiment of this utility model, a water level monitoring device includes a fixed plate 1; multiple sets of fixed rods 11 are fixedly connected to the bottom end of the fixed plate 1; pins 12 are fixedly connected to the bottom end of the fixed rods 11; a support frame 13 is fixedly connected to the top end of the fixed plate 1; a first fixed seat 14 is fixedly connected to the side wall of the support frame 13; a second fixed seat 15 is fixedly connected to the side wall of the first fixed seat 14; a crossbar 16 is rotatably connected to the middle of the second fixed seat 15; a float 17 is fixedly connected to the top end of the crossbar 16; a pressure plate 19 is fixedly connected to the top end of the crossbar 16; the pressure plate 19 is located near the end of the support frame 13; an alarm 18 is fixedly connected to the top end of the first fixed seat 14; during operation, the fixed plate 1 is placed at the water level to be monitored, and pressure is applied to the fixed plate 1, causing the multiple sets of pins 12 to insert into the soil, thus fixing the water level. The plate 1 is fixed as a whole. When the water level at the detection location rises, the float 17 contacts the water level, and the water level gradually rises. The float 17 drives the crossbar 16 to rotate in the middle of the first fixed seat 14. When the float 17 and the water level rise to the moving height, the pressure plate 19 at the top of the crossbar 16 will contact the alarm 18. The pressure plate 19 applies pressure to the alarm 18 and presses it down. After the alarm 18 is pressed down, it can send a water level detection signal to detect the water level. The float 17 is driven to rotate by buoyancy, which drives the fixed plate 1 and triggers the pressure plate 19 to contact the alarm 18, realizing a purely mechanical water level detection. It does not rely on an external power source, solves the problem of cumbersome power traction in remote areas, reduces the difficulty of equipment deployment, reduces the failure rate when using electronic components, improves the stability and durability of the fixed plate 1, and reduces maintenance costs and frequency.

[0025] like Figures 1 to 3As shown, a sliding seat 2 is slidably connected to the side wall of the support frame 13; a third fixed seat 21 is fixedly connected to the side wall of the sliding seat 2; a pin 22 is slidably connected to the middle of the third fixed seat 21; multiple sets of insertion holes 23 are fixedly connected to the side wall of the support frame 13; and a marking line 24 is fixedly connected to the side wall of the support frame 13. During operation, after the fixed plate 1 is fixed as a whole, pressure can be applied to the sliding seat 2 to slide it on the side wall of the support frame 13. After the sliding seat 2 slides to a specified height, the pin 22 can be inserted into the middle of the third fixed seat 21 until it is inserted into the middle of the insertion hole 23 to fix the sliding seat 2 as a whole. The marking line 24 can be used as a reference for adjusting the height of the sliding seat 2, so that the sliding seat 2 can be freely set for different water level thresholds. By sliding the sliding seat 2 on the side wall of the support frame 13, the height of the sliding seat 2 can be freely adjusted, and different water level monitoring thresholds can be flexibly set, enabling the device to play an effective monitoring role in various complex scenarios and expanding the application range of the water level monitoring device.

[0026] like Figures 1 to 3 As shown, a magnetic block 3 is fixedly attached to the top of the pin 22; a square hole 31 is provided on the side wall of the pin 22; a blocking rod 32 is fixedly attached to the side wall of the third fixing seat 21; the blocking rod 32 passes through the middle of the square hole 31; during operation, after the pin 22 is inserted into the middle of the third fixing seat 21, the magnetic block 3 at the top of the pin 22 can be attracted to the middle of the insertion hole 23, so that the pin 22 is tightly fitted into the inside of the insertion hole 23 after the fixed sliding seat 2 is fixed. The blocking rod 32 and the square hole 31 cooperate to keep the pin 22 fixed in place. The third fixing seat 21 is located in the middle, so that the pin 22 will not be lost. The magnetic block 3 is attached to the middle of the socket 23. The magnetic force makes the pin 22 fit tightly with the socket 23, effectively resisting the loosening caused by water flow impact or vibration, and ensuring that the height setting of the sliding seat 2 remains stable during long-term monitoring. The blocking rod 32 locks the pin 22 inside the third fixing seat 21. Even if it is pulled by external force or frequently adjusted, the pin 22 will not fall off or be lost from the third fixing seat 21, ensuring the integrity of the adjustment mechanism.

[0027] like Figure 1 As shown, a baffle 4 is fixedly connected to the side wall of the sliding seat 2; the baffle 4 is located in the middle of the crossbar 16; multiple sets of round holes 41 are opened at the top of the baffle 4; the round holes 41 are evenly distributed at the top of the baffle 4; during operation, when the water level rises to a certain height and contacts the float 17, floating objects in the water will contact the float 17. The baffle 4 can block the floating objects around the float 17, so that the floating objects do not contact the float 17, and the water flow can continue to flow into the float 17 from the round holes 41 and contact the float 17; by blocking the floating objects around the float 17 by the baffle 4, the direct attachment or entanglement of floating objects such as leaves and debris on the float 17 is reduced, and the accumulation of floating objects can reduce the inability of the float 17 to rotate normally or trigger the water level signal, thus ensuring the accuracy of the monitoring data.

[0028] like Figures 4 to 5As shown, a weight-adding box 5 is fixedly attached to the top of the fixed plate 1; a pair of drainage grooves 51 are provided on the side wall of the weight-adding box 5; during operation, after the fixed plate 1 is fixed at the detection position, a heavier item can be added to the inside of the weight-adding box 5, so that the weight of the fixed plate 1 increases after it is fixed, and the drainage grooves 51 can accumulate more liquid inside the weight-adding box 5 and then flow in; by adding a heavier item to the weight-adding box 5, the overall weight of the fixed plate 1 can be significantly increased, reducing the risk of displacement caused by water flow impact, increasing the fixed plate 1's ability to maintain a fixed posture under complex water conditions, and improving the reliability of monitoring data.

[0029] like Figure 5 As shown, a resistance rod 6 is fixed to the side wall of the insertion foot 12; the resistance rod 6 is correspondingly arranged with the insertion foot 12; during operation, after the insertion foot 12 is inserted into the soil to fix the fixing plate 1, pressure can be applied to the top of the resistance rod 6, and the pressure is transmitted to the insertion foot 12 to insert the insertion foot 12 into the soil, making it easier for the insertion foot 12 to be inserted into the soil; by applying stable pressure to the resistance rod 6 in soils with different hardness, the insertion depth of the insertion foot 12 is controllable and uniform, reducing the difficulty of inserting the insertion foot 12 due to excessively hard soil.

[0030] Working principle: The fixing plate 1 is placed at the water level to be detected. Pressure is applied to the fixing plate 1, causing multiple sets of pins 12 to insert into the soil and fix the fixing plate 1 in place. When the water level at the detection location rises, the float 17 contacts the water level, and the water level gradually rises. The float 17 drives the crossbar 16 to rotate in the middle of the first fixing seat 14. When the float 17 and the water level rise to the moving height, the pressure plate 19 at the top of the crossbar 16 contacts the alarm 18, and the pressure plate 19 applies pressure to the alarm 18. Pressing the alarm 18 sends a water level detection signal to monitor the water level. Once the fixing plate 1 is fixed, pressure is applied to the sliding seat 2 to slide it against the side wall of the support frame 13. After the sliding seat 2 reaches the specified height, the pin 22 can be inserted into the middle of the third fixing seat 21, all the way to the middle of the socket 23, to fix the sliding seat 2. The marking 24 serves as a reference for adjusting the height of the sliding seat 2, allowing it to freely adjust to different water level thresholds. When the pin 22 is inserted into the middle of the third fixing seat 21, the magnet 3 on the top of the pin 22 can be attracted to the middle of the insertion hole 23, so that the pin 22 is tightly fitted into the inside of the insertion hole 23 after the fixing sliding seat 2 is fixed. The blocking rod 32 and the square hole 31 cooperate to fix the pin 22 in the middle of the third fixing seat 21, so that the pin 22 will not be lost. When the water level rises to a certain height and contacts the float 17, the floating objects in the water will contact the float 17. The baffle 4 can block the floating objects around the float 17, so that the floating objects are not lost. The floating object does not contact the float 17, and the water can continue to flow into the round hole 41 and contact the float 17. After fixing the fixing plate 1 at the detection position, a heavier item can be added to the inside of the weight box 5, so that the weight of the fixing plate 1 increases after it is fixed. The trough 51 can accumulate more liquid inside the weight box 5 and then flow in. After the pin 12 is inserted into the soil to fix the fixing plate 1, pressure can be applied to the top of the resistance rod 6. The pressure is transmitted to the pin 12 and inserts the pin 12 into the soil, making it easier to insert the pin 12 into the soil.

[0031] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
