DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. 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.

[0022] like Figures 1 to 4 As shown, a hydraulic water level measuring device comprises a base 1, and air bags 2 are fixedly installed on the four sides of the base 1, which are used to provide buoyancy to the device so that the device floats on the water surface. A door-shaped bracket 3 is fixedly installed on the top of the base 1 by bolts, and a horizontally extending winding wheel 4 is rotatably installed on the bracket 3. The left and right ends of the winding wheel 4 are coaxially provided with mounting shafts 5, and the two mounting shafts 5 are rotatably installed on the left and right vertical walls of the bracket 3 through bearings. The mounting shaft 5 at the right end extends to the outside of the bracket 3 and is fixedly installed with a crank handle, which is convenient for rotating the winding wheel 4; and a positioning plate 6 is also fixedly installed on the mounting shaft 5 at the right end by bolts, and a locking screw 7 for pressing against the vertical wall on the right side of the bracket 3 is screwed on the positioning plate 6, which is convenient for locking the winding wheel 4. A measuring rope 8 is wound around the winding wheel 4, and a scale is provided on the measuring rope 8. A counterweight block 9 is fixedly connected to the free end of the measuring rope 8. A vertical through-groove is provided on the base 1 below the winding wheel 4, which is convenient for the measuring rope 8 to pass downward.

[0023] like Figure 3 As shown, a swing rod 10 is movably mounted on the base 1, and the swing rod 10 includes a swing arm 11 extending vertically, a handle is provided at the upper end of the swing arm 11, and a cross bar 12 bent backward at 90 degrees is integrally formed at the lower end of the swing arm 11, a connecting plate 13 is fixedly mounted on the front end of the top wall of the bracket 3 by bolts, and a rotating shaft 14 extending forward and backward is fixedly mounted on the middle part of the swing arm 11 by bolts, and the rotating shaft 14 is rotatably mounted on the connecting plate 13 through a bearing. One end of the cross bar 12 away from the swing arm 11 extends to the bottom of the winding wheel 4, and a first wire hole 15 vertically penetrated is provided on the cross bar 12 located below the winding wheel 4.

[0024] A horizontal plate 16 is fixedly installed between the two vertical walls of the bracket 3 located below the horizontal rod 12 by bolts. A second wire hole 17 is vertically penetrated in the middle of the horizontal plate 16, and the measuring rope 8 passes through the first wire hole 15 and the second wire hole 17 in sequence.

[0025] A movable plate 18 is installed on the bracket 3 for transverse sliding. Figure 2As shown, a slide bar 19 is fixedly installed between the two vertical walls of the bracket 3 by bolts. The slide bar 19 extends horizontally to the left and right parallel to the axis of the winding wheel 4, and two slide bars 19 are arranged side by side up and down. A slide seat 20 matching the slide bar 19 is fixedly installed on the rear side of the movable plate 18 by bolts, thereby providing support and guidance for the movable plate 18. A guide wheel 21 matching the measuring rope 8 is rotatably installed on the front side of the movable plate 18. The height of the guide wheel 21 is located between the first wire hole 15 and the second wire hole 17. The axis of the guide wheel 21 extends horizontally and the axis of the guide wheel 21 extends forward and backward perpendicular to the moving direction of the movable plate 18, so that the guide wheel 21 and the first wire hole 15 and the second wire hole 17 remain in the same vertical plane. A spring 22 is provided on the bracket 3 for driving the guide wheel 21 to deviate from the upper side of the second wire hole 17. Specifically, a stopper 23 matching the slide 20 is fixedly installed on the slide rod 19 located on the left side of the slide 20 by bolts. When the slide 20 contacts the stopper 23, the guide wheel 21 deviates to the left above the second wire hole 17, and the stopper 23 limits the movement of the slide 20. Springs 22 are respectively mounted on the two slide rods 19, and the right end of the spring 22 abuts against the vertical wall on the right side of the bracket 3, and the left end abuts against the right side of the corresponding slide 20.

[0026] When measuring the water level, firstly, the swing rod 10 is rotated to adjust the first wire hole 15 so that the first wire hole 15 is moved to the position just above the second wire hole 17; Figure 1 As shown, the measuring rope 8 between the first wire hole 15 and the second wire hole 17 is wound around the left side of the guide wheel 21, and the counterweight 9 is pulled downward by gravity to pull the measuring rope 8, and the measuring rope 8 between the first wire hole 15 and the second wire hole 17 is vertically tensioned and straightened, so that the measuring rope 8 acts on the guide wheel 21 and drives the movable plate 18 to move to the right along the slide bar 19 and compresses the spring 22; the staff rotates the winding wheel 4 in a specific direction and releases the measuring rope 8. When the counterweight 9 sinks to the bottom of the water, the measuring rope 8 is no longer pulled downward by the counterweight 9. If the staff continues to release the measuring rope 8, the compressed spring 22 will stretch and drive the movable plate 18 and the guide wheel 21 to move to the left and deviate from the top of the second wire hole 17, as shown in FIG. Figure 4 As shown, the measuring rope 8 between the first wire hole 15 and the second wire hole 17 is bent. Therefore, when the staff observes that the measuring rope 8 between the first wire hole 15 and the second wire hole 17 is bent, it means that the counterweight 9 has sunk to the bottom of the water. At this time, stop releasing the measuring rope 8 and observe the scale line on the measuring rope 8 to read the value.

[0027] In order to facilitate the fixation of the swing rod 10, an ear plate 24 is welded on one side of the swing arm 11, and a positioning hole 25 is provided on the ear plate 24 and runs through the front and back. A limiting screw 26 is inserted in the positioning hole 25, and a screw hole 27 matching the limiting screw is provided on the connecting plate 13. When the limiting screw 26 is screwed into the screw hole 27, the first wire hole 15 is vertically aligned with the second wire hole 17.

[0028] Specifically, during the water level measurement process, when the winding wheel 4 is rotated forward to release the measuring rope 8, the limit screw 26 needs to be screwed into the screw hole 27 to limit the rotation of the swing rod 10 and keep the first wire hole 15 and the second wire hole 17 in a vertically aligned state; when the water level measurement is completed, the measuring rope 8 is reeled in by rotating the winding wheel 4 in the reverse direction. During the process of reeling in the measuring rope 8, the measuring rope 8 can be removed from the guide wheel 21, and the limit screw 26 can be screwed out of the screw hole 27. By swinging the swing rod 10 back and forth, the measuring rope 8 located below the winding wheel 4 is driven to move back and forth along the length direction of the winding wheel 4, so that the measuring rope 8 is evenly reeled on the winding wheel 4.

[0029] In order to prevent the measuring rope 8 from accidentally escaping from the guide wheel 21 , an annular groove 28 matching the measuring rope 8 is provided on the outer circumference of the guide wheel 21 .
