Description

Technical Field

[0001] This utility model relates to the field of natural disaster early warning technology, and in particular to an early warning device based on the flood volume of small watersheds in mountainous areas. Background Technology

[0002] Mountainous watersheds are prone to sudden flooding due to their complex terrain and concentrated rainfall. Flood magnitude early warning equipment is needed to predict and warn of potential flooding in advance, protecting people's lives and property.

[0003] Existing flood magnitude early warning equipment is usually installed on the bank with a base, and then the monitoring equipment is placed in the water by extending the extension rod to predict flood disasters. However, after the extension rod is extended, the base is prone to instability due to the shift of the center of gravity, which increases the risk of the whole system overturning.

[0004] Therefore, an early warning device based on the flood volume of a small watershed in a mountainous area has been developed that can enhance the stability of the fixed pole and prevent it from tilting when the extension pole is extended. Utility Model Content

[0005] To overcome the shortcomings of existing flood magnitude early warning devices, which are prone to instability due to center of gravity shift after the extension rod is extended, increasing the risk of overall overturning, this utility model provides an early warning device based on flood magnitude in small mountain watersheds that can enhance the stability of the fixed rod when the extension rod is extended, thus preventing the fixed rod from tipping over.

[0006] An early warning device based on the flood volume of a small watershed in a mountainous area includes a fixed rod, a support column, a fixed base plate, a connecting block, a second gear, a bidirectional motor, a chain, a third gear, an extension rod, a rotating gear, a rack, a stabilizing component, and an early warning component. The support column is connected to the lower left side of the fixed rod, and the fixed base plate is connected to the lower side of the support column. Connecting blocks are connected to both the front and rear sides of the middle of the fixed rod. A bidirectional motor is connected to the front connecting block, and a second gear is connected to the output shaft at the rear of the bidirectional motor. A third gear is rotatably connected to the right side of the front connecting block. A chain is wound between the second and third gears, and both the second and third gears mesh with the chain. An extension rod is slidably connected to the right side of the fixed rod, and a rotating gear is connected to the rear of the third gear. A rack is connected inside the extension rod, and the rotating gear meshes with the rack. A stabilizing component is provided on the connecting block to enhance stability. An early warning component for monitoring and warning of water conditions is provided between the fixed rod and the extension rod.

[0007] To further explain, a diagonal brace is provided between the fixed rod and the support column.

[0008] To further explain, the base plate has multiple mounting holes.

[0009] To further explain, the stabilizing component includes a gear frame, a first gear, and a fixed base. The gear frame is slidably connected between the connecting blocks. The first gear is connected to the output shaft on the front side of the bidirectional motor. The first gear meshes with the gear frame. Fixed bases are connected to the lower sides of both the front and rear parts of the gear frame.

[0010] To further explain, multiple fixing pins are provided on the lower side of each fixing base.

[0011] To further explain, the early warning component includes an alarm, a reel, a connecting rope, a drive motor, a flow detector, and a water level detector. The alarm is connected to the upper left side of the fixed rod, and the drive motor is connected to the front right side of the extension rod. The reel is connected to the output shaft of the drive motor, and the reel is rotatably connected to the extension rod. The connecting rope is wound around the reel, and the flow detector is connected to the lower side of the connecting rope. The flow detector and the alarm are electrically connected. The water level detector is connected to the right side of the extension rod, and the water level detector and the alarm are electrically connected.

[0012] The beneficial effects of this utility model are as follows: This utility model uses the rotation of the first gear to mesh with the gear frame, causing the gear frame to move downward along the connecting block, which in turn moves the fixing seat downward and inserts it into the soil. This achieves the effect of strengthening the stability of the fixing rod when the extension rod is extended, and preventing the fixing rod from tipping over. Attached Figure Description
