[0002] A diversion-type hydropower station is a hydropower station that generates electricity by diverting water through a gentle-slope diversion channel to form a required head (water level difference) with the natural water surface at a section of a river with a relatively steep slope and concentrated drop, or at a place where the riverbed elevations of adjacent rivers or river bends differ greatly. In order to ensure the normal operation of the diversion-type hydropower station, the use of a water level monitoring device is essential.

[0003] At present, with the development of technology, non-contact radar water level gauges are mostly used for water level monitoring of diversion-type hydropower stations. However, in the process of using the existing water level monitoring device with a radar water level gauge, after the upright rod and the extension rod are combined, it needs to be installed above the monitored water level, which makes the device have a certain distance from the shore, and the structure is fixed after installation, resulting in great inconvenience when the device needs to be repaired or replaced later. Therefore, we propose a water level monitoring device for a diversion-type hydropower station. Content of the Utility Model

[0004] The purpose of the utility model is to provide a water level monitoring device for a diversion-type hydropower station, which has the advantages of convenient maintenance or replacement, and solves the problem that in the process of using the existing radar water level gauge, after the upright rod and the extension rod are combined, it needs to be installed above the monitored water level, which makes the device have a certain distance from the shore, and the structure is fixed after installation, resulting in great inconvenience when the device needs to be repaired or replaced later.

[0006] Preferably, the outer diameter dimension of the supporting ring is larger than the outer diameter dimension of the movable sleeve.

[0007] Preferably, the positioning insertion rod is located inside the spring, and the positioning insertion rod and the positioning hole are adapted to each other.

[0008] Preferably, the inverted T-shaped push block penetrates through the bottom of the right end of the extension arm, and the lower end of the inverted T-shaped push block extends below the extension arm.
