[0026] The pulley assembly 3 is slidably mounted inside the support frame 1, can be moved to the top of the support frame 1 and spread out toward both sides, and is fixedly connected to the positioning plate;

[0027] The winding wheel 4 is arranged on one side of the support frame 1, and a rope is wound on the outer wall;

[0028] The mounting frame 5 is arranged at a distance on one side of the supporting frame 1, and is used to fix and install the test box, and a counterweight block 6 is added at the bottom;

[0029] There are four groups of movable positioning components 7, which are respectively arranged at the four corners of the fixing plate 2 at the bottom of the support frame 1, and are mainly used to cooperate with the support frame 1 for movement and fixation.

[0031] The pulleys are divided into a first fixed pulley 33, a second fixed pulley 34 and a third fixed pulley 35, wherein the first fixed pulley 33 and the second fixed pulley 34 are respectively located at the ends of the two connecting plates 32, and the third fixed pulley 35 is located at the top of the connecting seat 31. The three constitute Figure 3 In the structure shown, the rope on the winding wheel 4 is moved to the top of the mounting frame 5 through the cooperation of the first fixed pulley 33, the second fixed pulley 34 and the third fixed pulley 35, so that the staff can control the depth of the water flow measured by the test box by releasing or reeling in the winding wheel 4, and the adjustment is very convenient.
