Description

TECHNICAL FIELD

[0001] The utility model relates to water conservancy engineering technical field especially is related to a water conservancy water level monitoring devices. BACKGROUND

[0002] Water level refers to the height of the free water surface of a river or other water body above a certain base, and the change of water level is an important reference for displaying the water flow of the water body, which can be used for the prediction of hydrological information through the change of water level of the water body. Flood prevention and drought resistance, irrigation, navigation and water conservancy construction in practical application can play an important role. The data obtained by long-term monitoring of water level is the basic basis for the planning and design of water conservancy, hydropower, bridge, channel, port and urban water supply and drainage construction.

[0003] In related technology, reference can be made to the Chinese utility model patent with the authorization announcement number CN221764606U, which discloses a water conservancy water level monitoring device, which comprises a fixing mechanism, a supporting rod, an adjusting assembly and an ultrasonic water level detection mechanism. The supporting rod is fixedly connected with the fixing mechanism. The adjusting assembly comprises a rotating piece, a fixed piece, a driving piece, a storage battery, a supporting seat and a solar panel. The rotating piece is fixedly connected with the supporting rod. The fixed rod is fixedly connected with the rotating piece. The driving piece is rotatably connected with the fixed rod. The storage battery is fixedly connected with the fixed rod. The supporting seat is fixedly connected with the storage battery. The solar panel is fixedly connected with the supporting seat and located above the supporting seat. The ultrasonic water level detection mechanism is fixedly connected with the driving piece and located on the outer side of the driving piece. When in use, the solar panel converts light energy into electrical energy and stores it in the storage battery. The rotating piece is used to adjust the angle of the ultrasonic water level detection mechanism. The driving piece is used to adjust the installation height of the ultrasonic water level detection mechanism.

[0004] The length of the supporting rod used to install the water level detection component is usually long, so that the detection component on the supporting rod can be as far away from the edge of the water surface as possible, avoiding the exposure of the water bottom in the monitoring area of the water level radar after the water surface narrows down. The supporting rod is usually thin and light to reduce the tension at the connection between the supporting rod and the fixed rod. Due to the characteristics of the thin and long supporting rod, the bearing capacity of the supporting rod is poor, and it is easy to bend in the use process due to the collision of objects or wind impact. The water level detection component such as water level radar or ultrasonic water level monitor needs to be perpendicular to the water surface. If the supporting rod is bent, the stability of the monitoring equipment will be affected, thereby reducing the accuracy of the monitoring value. UTILITY MODEL CONTENTS
