Description

Technical Field

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

[0002] Water level monitoring and early warning devices play a crucial role in the water conservancy field. They can monitor water level changes in real time, provide key data support for the safe operation of water conservancy facilities, and issue timely warnings when water levels are abnormal, thereby effectively preventing potential flood risks.

[0003] Existing water level monitoring and early warning technologies often suffer from fixed structures and poor versatility, making them unsuitable for monitoring waters of varying depths. Furthermore, traditional equipment typically requires lifting or retracting the measuring components to view water level measurements, a cumbersome and inefficient process. In addition, existing technologies lack robust early warning mechanisms for abnormal water levels, often relying on manual inspections or simple mechanical triggers, failing to achieve automated monitoring and timely warnings, thus increasing safety risks to water conservancy facilities. Therefore, those skilled in the art have proposed a water level monitoring and early warning device to address the problems described in the background. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a water level monitoring and early warning device. This addresses the problems of fixed structures and poor versatility often found in existing water level monitoring and early warning devices, making them unsuitable for monitoring waters of varying depths. Furthermore, the process of viewing water level measurement results using traditional equipment is cumbersome and inefficient. In addition, the early warning mechanisms for abnormal water levels in existing technologies are inadequate, often relying on manual inspections or simple mechanical triggers, failing to achieve automated monitoring and timely warnings, thus increasing the safety risks to water conservancy facilities.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a water level monitoring and early warning device, comprising a bracket, a fixing bolt installed at one end of the bracket, a through hole opened at the end of the bracket away from the fixing bolt, a sleeve inserted into the through hole, a connecting rod installed on one side of the sleeve, a scale installed on the connecting rod, a toothed groove opened on the side of the sleeve facing the connecting rod, a float installed inside the sleeve, a scale indicator rod vertically installed at the middle of the float, a laser rangefinder installed on the upper side of the float, an audible and visual alarm installed on the bracket, a main control circuit board installed on one side of the audible and visual alarm, the main control circuit board including a data processing module, a water level monitoring module, a wireless communication module and an early warning module, a motor installed at the end of the bracket facing the through hole, a gear installed at the output end of the motor, a pressing block installed below the gear, and a hydraulic rod installed below the pressing block.

[0006] Preferably, one side of the gear engages with the tooth groove, and the bottom side of the gear engages with the pressing block. A limit rod is installed on the bracket, and the end of the connecting rod away from the sleeve is slidably sleeved with the limit rod. The gear is driven to rotate by the motor, causing the sleeve to penetrate deeper into the water surface until the bottom of the sleeve contacts the bottom. This structure allows the depth of the sleeve to be adjusted, making the device suitable for waters of different depths. When the gear stops rotating, the hydraulic rod can extend and retract to engage the pressing block with the gear, thereby locking the gear.

[0007] Preferably, a limiting strip is installed on the side of the sleeve away from the connecting rod, and a limiting groove is formed on the inner wall of the through hole. The limiting groove and the limiting strip are slidably engaged. Through the sliding engagement between the limiting strip and the limiting groove, it can be ensured that the sleeve will not rotate in the through hole.

[0008] Preferably, the scale indicator rod is slidably sleeved with the top of the sleeve, and the scale indicator rod is L-shaped to ensure the stability of the scale indicator rod.

[0009] Preferably, the sleeve has a water inlet on its peripheral sidewall, and the bottom of the sleeve is open to facilitate water intake and allow it to float.

[0010] Compared with the prior art, this utility model provides a water level monitoring and early warning device, which has the following beneficial effects:

[0011] Through design, the water level monitoring and early warning device in this utility model includes a bracket, a sleeve, a float, a scale indicator rod, a laser rangefinder, a main control circuit board, and an audible and visual alarm. The motor-driven gear on the bracket drives the sleeve to penetrate below the water surface until it contacts the bottom. Then, the hydraulic rod drives the pressure block locking gear to fix the depth of the sleeve. This design makes the depth of the sleeve adjustable, which can adapt to waters of different depths and improves the versatility and applicability of the device.

[0012] The scale moves up and down with the depth of the sleeve via a connecting rod, and the initial 0 mark is aligned with the top of the sleeve. The float floats up under the pressure of the water. The L-shaped scale indicator rod on the top of the float works in conjunction with the scale to intuitively display the water level height. The water level measurement results are moved to a position on the support away from the water surface, making it convenient for on-site personnel to view. This avoids the trouble of having to lift or retract the traditional equipment to view the water level measurement results.

[0013] A laser rangefinder is installed on the upper part of the float. When the laser rangefinder detects that the distance between the float and the top side wall of the sleeve exceeds the preset distance, the data processing module of the main control circuit board receives the data and transmits it to the remote monitoring center in real time through the wireless communication module, reminding relevant personnel to take timely measures. At the same time, the data processing module sends a control signal to the early warning module, causing the audible and visual alarm to emit an audible and visual alarm signal, reminding on-site personnel to respond in time. This realizes the automation of water level monitoring and the timeliness of early warning, effectively ensuring the safe operation of water conservancy facilities. Attached Figure Description

A connecting rod 14 is installed on one side of the sleeve 10, and a scale 15 is installed on the connecting rod 14. A toothed groove 12 is opened on the side of the sleeve 10 facing the connecting rod 14. A float 16 is set inside the sleeve 10, and a scale indicator rod 17 is vertically installed in the middle of the float 16. A laser rangefinder 18 is installed on the upper side of the float 16. An audible and visual alarm 20 is installed on the bracket 1. A main control circuit board 19 is set on one side of the audible and visual alarm 20. The main control circuit board 19 includes a data processing module, a water level monitoring module, a wireless communication module, and an early warning module. A motor 6 is installed at the end of the bracket 1 facing the through hole 4. A gear 7 is installed at the output end of the motor 6. A pressing block 9 is set below the gear 7, and a hydraulic rod 8 is installed on the lower side of the pressing block 9.

[0021] Please see Figure 1 , Figure 2 , Figure 3 and Figure 4 One side of gear 7 meshes with tooth groove 12, and the bottom side of gear 7 meshes with pressing block 9. A limit rod 3 is installed on bracket 1. The end of connecting rod 14 away from sleeve 10 is slidably sleeved with limit rod 3. Motor 6 drives gear 7 to rotate, causing the meshing sleeve 10 to penetrate deeper into the water until the bottom of sleeve 10 contacts the bottom. This structure allows the depth of sleeve 10 to be adjusted, making the device suitable for waters of different depths. When gear 7 stops rotating, it can... The hydraulic rod 8 extends and retracts, causing the pressure block 9 to mesh with the gear 7, thereby locking the gear 7. A limit strip 13 is installed on the side of the sleeve 10 away from the connecting rod 14. A limit groove 5 is formed on the inner wall of the through hole 4. The limit groove 5 and the limit strip 13 are slidably engaged. Through the sliding engagement of the limit strip 13 and the limit groove 5, it can be ensured that the sleeve 10 will not rotate within the through hole 4. The scale indicator rod 17 is slidably sleeved on the top of the sleeve 10. The scale indicator rod 17 is L-shaped to ensure the scale indication. To ensure the stability of the rod 17, a water inlet 11 is opened on the circumferential wall of the sleeve 10. The bottom of the sleeve 10 is open to facilitate water intake, allowing the float 16 to float. When the float 16 floats to the water surface, the position indicated by the scale indicator rod 17 is the water level. Through the interaction of the scale ruler 15 and the scale indicator rod 17, the water level measurement result can be moved to a position on the support 1 away from the water surface for on-site personnel to observe. A laser rangefinder 18 is installed on the upper part of the float 16. When the laser rangefinder 18 detects that the distance between the float 16 and the top side wall of the sleeve 10 exceeds the preset distance, it sends data to the main control circuit board 19. The data processing module in the main control circuit board 19 receives the data and transmits it to the remote monitoring center in real time through the wireless communication module, reminding relevant personnel in the monitoring center to take timely measures. At the same time, the data processing module immediately sends a control signal to the early warning module, causing the audible and visual alarm to emit an audible and visual alarm signal, reminding relevant personnel on-site to take timely measures.

[0022] The water level monitoring and early warning device in this utility model includes a bracket 1, a sleeve 10, a float 16, a scale indicator rod 17, a laser rangefinder 18, a main control circuit board 19, and an audible and visual alarm 20.

[0023] A number of fixing bolts 2 are provided at one end of the bracket 1 for insertion into the ground to position the bracket 1. A through hole 4 is provided at the end of the bracket 1 away from the fixing bolts 2, and the sleeve 10 is slidably inserted into the through hole 4. A limit groove 5 is vertically provided on the inner wall of the through hole 4. A limit strip 13 is vertically installed on the outer wall of the sleeve 10. Through the sliding engagement of the limit strip 13 and the limit groove 5, it can be ensured that the sleeve 10 will not rotate in the through hole 4. A connecting rod 14 is installed on one side of the sleeve 10. The connecting rod 14 is slidably sleeved with the limit rod 3 vertically installed on the bracket 1. A scale 15 is provided on the connecting rod 14.

[0024] A toothed groove 12 is provided on the outer wall of the sleeve 10 away from the limiting strip 13. A motor 6 is installed on the side of the through hole 4. The output end of the motor 6 drives the gear 7. The gear 7 meshes with the toothed groove 12 on the outer wall of the sleeve 10. A pressing block 9 is provided on the lower side of the gear 7. The pressing block 9 meshes with the teeth of the gear 7. A hydraulic rod 8 is installed at the bottom of the pressing block 9. When the gear 7 stops rotating, the hydraulic rod 8 can extend and retract to drive the pressing block 9 to mesh with the gear 7, thereby locking the gear 7.

[0025] When using the device, the bracket 1 is fixed to the ground. Then, the motor 6 drives the gear 7 to rotate, causing the sleeve 10 to engage and penetrate deeper into the water until the bottom of the sleeve 10 contacts the bottom. Then, the hydraulic rod 8 drives the pressure block 9 to lock the gear 7, fixing the depth of the sleeve 10. This structure allows the depth of the sleeve 10 to be adjusted, making the device suitable for waters of different depths. When the depth of the sleeve 10 is fixed, the scale 15 moves up and down with the depth of the sleeve 10 via the connecting rod 14, ensuring that the initial 0 mark of the scale 15 is aligned with the top of the sleeve 10.

[0026] The float 16 inside the sleeve 10 floats upward under the pressure of the water. An L-shaped scale indicator rod 17 is installed on the top of the float 16. When the float 16 is at the bottom of the sleeve 10, the scale indicator rod 17 is aligned with the 0 mark of the scale 15. As the float 16 floats out of the water, the position indicated by the scale indicator rod 17 is the water level. Through the action of the scale 15 and the scale indicator rod 17, the water level measurement result can be moved to a position away from the water surface on the support 1 for on-site personnel to view, avoiding the problem that the water level measurement result of traditional equipment needs to be lifted or retracted to view.

[0027] A laser rangefinder 18 is installed on the upper part of the float 16, and a main control circuit board 19 and an audible and visual alarm 20 are installed on the bracket 1. The main control circuit board 19 includes a data processing module, a water level monitoring module, a wireless communication module, and an early warning module. The laser output end of the laser rangefinder 18 faces the top side wall of the sleeve 10. As the buoy rises and falls, when the laser rangefinder 18 detects that the distance between the float 16 and the top side wall of the sleeve 10 exceeds the preset distance, it sends data to the main control circuit board 19. The data processing module in the main control circuit board 19 receives the data and transmits it to the remote monitoring center in real time through the wireless communication module, reminding the relevant personnel in the monitoring center to take timely measures. At the same time, the data processing module immediately sends a control signal to the early warning module, causing the audible and visual alarm to emit an audible and visual alarm signal, reminding the relevant personnel on site to take timely measures.
