[0028] like Figure 1-4 As shown, a water conservancy engineering measurement bridge of the utility model comprises a bridge body 1, a side plate 2 is welded at the bottom of the bridge body 1, a first external threaded rod 4 is welded on the side of the side plate 2, an extension plate 3 is arranged on the side of the side plate 2, a first slide groove 20 is arranged on the side of the extension plate 3, the first external threaded rod 4 is located inside the first slide groove 20, and the surface of the first external threaded rod 4 is on the extrusion turntable 5. By installing the extrusion turntable 5, when the first slide groove 20 lowers the extension plate 3 to a suitable position, the extrusion turntable 5 is used to increase the friction between the extension plate 3 and the side plate 2 to fix it. When in use It is very convenient. The bearing 8 is welded inside the extension plate 3, the fixing rod 7 is welded inside the bearing 8, the frame 9 is welded on the surface of the fixing rod 7, a cavity 10 is opened inside the frame 9, a slideway 11 is opened on the surface of the frame 9, a pulp board 13 is installed inside the cavity 10, a second externally threaded rod 14 is welded on the surface of the pulp board 13, the second externally threaded rod 14 is located inside the slideway 11, and a nut 12 is installed on the surface of the second externally threaded rod 14. By installing the frame 9, the frame 9 can be used to provide the pulp board 13 with installation and disassembly effects, and the pulp board 13 can be cleaned more conveniently, which is very convenient to use.

[0029] A limiting rod 15 is welded on the side of the side plate 2, and a second sliding groove 19 is opened on the side of the extension plate 3. The limiting rod 15 is located inside the second sliding groove 19. A limiting ring 16 is welded on the surface of the limiting rod 15, and the side of the limiting ring 16 is attached to the side of the extension plate 3. By installing the limiting rod 15, the limiting rod 15 can provide a limiting effect for the extension plate 3, so that the extension plate 3 will not rotate with the first external threaded rod 4, and the stability is strong during use.

[0030] A fixed plate 17 is welded to the bottom of the extension plate 3, and a speed measuring device 18 is welded to the side of the fixed plate 17. The extension plate 3 is symmetrically distributed. By installing the speed measuring device 18, when the paddle plate 13 is impacted by the water flow, the fixed rod 7 will rotate, and the paddle plate 13 will rotate along with the fixed rod 7.

Then the bridge body 1 is installed in a suitable position until the paddle board 13 is immersed in water. When the paddle board 13 is impacted by the water flow, the fixing rod 7 will rotate, and the paddle board 13 will rotate with the fixing rod 7. At this time, the speed measuring device 18 is used to measure the rotation of the paddle board 13, so as to understand the situation here. The water flow rate is such that when the water level at the bottom of the bridge frame drops during the use of the water conservancy project measurement bridge frame, the extrusion turntable 5 can be rotated to release the fixation of the extension plate 3, and then the extension plate 3 can be lowered to a suitable position through the first slide groove 20, and then the extrusion turntable 5 can be rotated again to increase the friction between the extension plate 3 and the side plate 2 to fix it. At this time, the extension plate 3 can provide a moving effect for the water conservancy project measurement bridge frame, and it can be adjusted according to the position of the water surface during use, which is very convenient to use. When it is necessary to clean the paddle board 13, the nut 12 can be removed first, and then the paddle board 13 can be directly taken out. At this time, it is more convenient to clean the paddle board 13, and it is very convenient to use.
