Description

Technical Field

[0001] This utility model relates to the technical field of flood control detection and early warning equipment, specifically a flood control detection and early warning device. Background Technology

[0002] To ensure the safety of rivers, lakes, reservoirs, and other water bodies, flood control detection and early warning equipment is often used to detect and warn of water levels. A utility model patent with patent application number CN202323428977.7 discloses a water conservancy flood control early warning device. This device uses a protective pipe to shield the outside of the device, ensuring that water flow is filtered by the filter screen on the filter cover before entering the protective pipe through the inlet. This prevents debris or impurities from adhering to the surface of the float plate and affecting the accuracy of detection. Simultaneously, an air vent is used to balance the pressure inside the protective pipe, ensuring that the detected water level matches the water level outside the protective pipe. The filter plate also filters the air vent. However, according to the disclosed technical solution, existing flood control detection and early warning equipment often fails to accurately detect water depth when there are large waves, thus compromising the reliability of early warning. Furthermore, after installation, it cannot adjust the warning depth in real time based on the reinforcement or damage status of the surrounding riverbanks and embankments, which is detrimental to ensuring water safety.

[0003] Therefore, how to design flood prevention detection and early warning devices has become a problem we need to solve. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a flood control detection and early warning device to solve the problems mentioned in the background technology. This utility model is reasonably designed, convenient to use, and suitable for water level detection and early warning.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a flood prevention detection and early warning device, comprising a base and a top plate. A measuring component is installed on the base, the measuring component including a measuring cylinder and a scale. A floating component is located inside the measuring cylinder, the floating component including a float and a roller. An observation component is installed inside the measuring cylinder, the observation component including a camera and an observation port. An early warning component is installed on the measuring cylinder, the early warning component including a flap and a button. A lifting component is installed on the top plate, the lifting component including a motor and a lead screw. A stabilizing component is installed on the measuring cylinder, the stabilizing component including a filter hole and a partition.

[0006] Furthermore, the bottom end of the measuring cylinder is welded to the top of the base, the top end of the measuring cylinder is welded to the bottom of the top plate, the float is placed inside the measuring cylinder, the rollers are bolted to both sides of the float, and the rollers are clamped to the inner wall of the measuring cylinder.

[0007] Furthermore, the top plate has an air hole on its inner side, the inner side of the top of the measuring cylinder is connected to the outer side of the measuring cylinder through the air hole, the filter hole is opened at the bottom of the measuring cylinder, the inner side of the bottom of the measuring cylinder is connected to the outer side of the measuring cylinder through the filter hole, the partition is welded to the inner wall of the bottom of the measuring cylinder, and the inner side of the partition has a through hole.

[0008] Furthermore, the camera is bolted to the inside of the float, a light is installed on the camera, the scale is opened on the inner wall of the measuring cylinder, and the observation port is installed on one side of the measuring cylinder.

[0009] Furthermore, the motor is bolted to the top of the top plate, the top end of the lead screw is keyed to the output shaft of the motor, and the bottom end of the lead screw passes through the top plate through a bearing and extends to the inside of the measuring cylinder.

[0010] Furthermore, a sliding sleeve is fitted on the outer side of the lead screw, and the inner side of the sliding sleeve is threaded onto the outer side of the lead screw. A stop block is integrally formed at the bottom end of the sliding sleeve.

[0011] Furthermore, both sides of the flap are fitted onto the outer side of the sliding sleeve, the bottom of the flap is locked onto the top of the stop block, and the button is installed on the inner side of the flap by bolts.

[0012] Furthermore, the bottom of the button extends to the bottom of the flap, and an external alarm is connected to the top plate. The button is connected to the alarm via a wire.

[0013] Beneficial effects: 1. When using this flood detection and early warning device, the base is installed at the bottom of water bodies such as rivers, lakes, and reservoirs. Water enters the inner side of the measuring cylinder through the filter holes, and then flows to the top of the measuring cylinder through the through holes in the partition. Air in the measuring cylinder is discharged outward from the top plate through the air holes. The float moves up and down inside the measuring cylinder under buoyancy via rollers, which also moves the camera. By observing the water level in the measuring cylinder at the corresponding scale mark, the water depth can be effectively detected. When large waves are generated on the water surface, the water pressure inside the measuring cylinder is kept consistent with the water pressure in the water body through the filter holes and through holes, so that the waves on the water surface will not be transmitted to the inner side of the measuring cylinder, effectively ensuring the stability of the float's up and down movement. The float moves up to the bottom of the movable plate and presses the button to perform the early warning work, which can effectively ensure the accuracy of water level detection and thus ensure the reliability of the early warning work.

[0014] 2. When this flood control detection and early warning device is in use, after the dikes, riverbanks, and other embankments around the water body are damaged or repaired and reinforced, the warning depth of the water level is adjusted according to the condition of the dikes. During the adjustment, the motor is turned on, and the motor drives the lead screw to rotate in the forward or reverse direction. This causes the lead screw to drive the sliding sleeve to move up and down through the thread. The sliding sleeve drives the movable plate to rise and fall through the stop block until the water level value of the scale at the bottom of the movable plate matches the required warning depth. This allows for quick adjustment of the warning value of the water level depth according to the condition of the dikes, improving the adaptability of the early warning monitoring work for water bodies and enhancing the safety of the early warning detection of water bodies.

The top end of the lead screw 16 is keyed to the output shaft of the motor 15. The bottom end of the lead screw 16 passes through the top plate 2 via a bearing and extends to the inside of the measuring cylinder 3. A sliding sleeve 17 is fitted onto the outer side of the lead screw 16. The inner side of the sliding sleeve 17 is threaded onto the outer side of the lead screw 16. A stop block 18 is integrally formed at the bottom end of the sliding sleeve 17. Both sides of the movable plate 12 are fitted onto the outer side of the sliding sleeve 17. The bottom of the movable plate 12 is locked onto the top of the stop block 18. The button 13 is bolted onto the inner side of the movable plate 12. When the dikes, riverbanks, and other embankments around the water body are damaged or repaired and reinforced, the warning depth of the water level is adjusted according to the condition of the dikes.

[0023] In this embodiment, the bottom end of the measuring cylinder 3 is welded to the top of the base 1, and the top end of the measuring cylinder 3 is welded to the bottom of the top plate 2. The float 9 is placed inside the measuring cylinder 3, and the rollers 11 are bolted to both sides of the float 9. The rollers 11 are secured to the inner wall of the measuring cylinder 3. An air hole 14 is provided on the inner side of the top plate 2, and the inner side of the top end of the measuring cylinder 3 is connected to the outer side of the measuring cylinder 3 through the air hole 14. The filter hole 5 is located at the bottom end of the measuring cylinder 3. The inner side is connected to the outer side of the measuring cylinder 3 through the filter hole 5. The partition 6 is welded to the inner wall of the bottom end of the measuring cylinder 3. The inner side of the partition 6 has a through hole 7. The camera 10 is bolted to the inner side of the float 9. The camera 10 is equipped with a light. The scale mark 8 is opened on the inner wall of the measuring cylinder 3. The observation port 4 is installed on one side of the measuring cylinder 3. The bottom of the button 13 extends to the bottom of the flap 12. An alarm is externally connected to the top plate 2. The button 13 is open to the outside of the measuring cylinder 3. The device is connected to an alarm via an electrical wire. In use, the base 1 is installed at the bottom of a body of water such as a river, lake, or reservoir. Water enters the inside of the measuring cylinder 3 through the filter hole 5, and then flows to the top of the measuring cylinder 3 through the through hole 7 in the partition plate 6. Air inside the measuring cylinder 3 is discharged outward from the top plate 2 through the air hole 14. The float 9 moves up and down inside the measuring cylinder 3 under buoyancy via the roller 11, which also moves the camera 10. The camera 10 observes the position of the water level inside the measuring cylinder corresponding to the scale mark 8, which can effectively detect the water depth. When large waves are generated on the water surface, the water pressure inside the measuring cylinder 3 is kept consistent with the water pressure through the filter hole 5 and the through hole 7, so that the waves on the water surface will not be transmitted to the inside of the measuring cylinder 3, effectively ensuring the stability of the up and down movement of the float 9. The float 9 moves up to the bottom of the flap 12 and presses the button 13 to start the warning. This can effectively ensure the accuracy of water level detection and thus ensure the reliability of the warning work.

[0024] This flood control detection and early warning device provides power to all electrical equipment via an external power source. In use, the base 1 is installed at the bottom of rivers, lakes, reservoirs, or other bodies of water. Water enters the inner side of the measuring cylinder 3 through the filter hole 5, and then flows to the top of the measuring cylinder 3 through the through-hole 7 in the partition plate 6. Air inside the measuring cylinder 3 is discharged outwards from the top plate 2 through the air hole 14. The float 9 moves up and down inside the measuring cylinder 3 under buoyancy via the roller 11, moving the camera 10. The camera 10 observes the water level inside the measuring cylinder at the corresponding scale mark 8, effectively detecting the water depth. When large waves occur on the water surface, the water pressure inside the measuring cylinder 3 remains consistent with the water pressure through the filter hole 5 and through-hole 7, preventing the waves from being transmitted to the inner side of the measuring cylinder 3. This effectively ensures the stability of the float 9's up-and-down movement until the float... Move 9 upwards to the bottom of the flap 12 and press button 13 to initiate the warning operation. This effectively ensures the accuracy of water level detection and the reliability of the warning operation. When the dikes, riverbanks, and other embankments around the water body are damaged or repaired and reinforced, the warning depth of the water level can be adjusted according to the condition of the dikes. During the adjustment, the motor 15 is turned on, and the motor 15 drives the lead screw 16 to rotate in the forward or reverse direction. This causes the lead screw 16 to drive the sliding sleeve 17 to move up and down through the thread. The sliding sleeve 17 drives the flap 12 to rise and fall through the stop block 18 until the water level value at the bottom of the flap 12 corresponds to the scale mark 8 and matches the required warning depth. This allows for quick adjustment of the warning value of the water level depth according to the condition of the dikes, improving the adaptability of the water body warning monitoring operation and enhancing the safety of the water body warning detection.
