[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] 1. The utility model provides a guide rod and a floating ring. The floating ring rises along the guide rod on the water surface as the water level rises and lowers as the water level decreases. The floating debris on the water surface can be blocked outside the floating ring, so that the ultrasonic wave emitted by the ultrasonic water level meter is not blocked by the floating debris on the water surface, resulting in inaccurate water level detection. In this way, the accuracy of ultrasonic water level detection can be improved.

[0013] 2. The utility model provides a telescopic cross bar, the length of which can be adjusted as needed, thereby adjusting the distance between the water surface measuring point and the shore, so as to facilitate flexible adjustment of the device according to the on-site installation environment.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] See also Figure 1 and Figure 3 In the embodiment of the utility model, a water level detection device for a water conservancy project includes a column 1, a telescopic cross bar 3, a water level monitoring terminal 11 and a photovoltaic power supply component 12. A telescopic cross bar 3 is arranged on one side of the upper part of the column 1. One end of the telescopic cross bar 3 is fixedly connected to a first pipe clamp 2 installed on the column 1. The telescopic cross bar 3 includes a rod barrel 301, a rod body 302 and a threaded rod 304. The rod body 302 is clearance-matched with the rod barrel 301. Threaded holes 303 are opened on the rod body 302 at equal intervals. The threaded rod 304 is rotatably installed on the rod barrel 301. 304, the threaded rod 304 is threadedly matched with the threaded hole 303, and an oblique support rod 4 is arranged between the column 1 and the telescopic cross bar 3, and the two ends of the oblique support rod 4 are respectively fixedly connected with the column 1 and the rod tube 301 of the telescopic cross bar 3, and the oblique support rod 4 can improve the firmness of the connection between the telescopic cross bar 3 and the column 1. When it is necessary to adjust the length of the telescopic cross bar 3, first screw the threaded rod 304 out of the threaded hole 303, and then the rod body 302 can be freely extended from the rod tube 301. After adjusting to the appropriate length, the threaded rod 304 is installed and locked.
