[0002] A portable water surface line measurement device is a tool for measuring the water surface line. The existing method for measuring the water surface line in a hydraulic model test is as follows: Select a model reference point, read the scale reading at the reference point through a level, obtain the elevation of the horizontal line of the center line of the level's objective lens, and then use the level and a water level gauge to successively measure the scale readings at each measured point when the end of the scale is flush with the upper surface of the water flow. Then, through the difference between the readings at the measured points and the reference point, calculate the elevation of the upper surface of the water flow at the measured points.

[0003] Currently, when measuring the water surface line in the market, the position of the level is generally adjusted manually, with a small adjustment range, unstable adjustment, and a limited number of adjustments, resulting in unstable and inaccurate measurement data. Utility Model Content

An adjustment component is installed on the inner wall of the transverse adjustment frame 11. A controller 2 is fixedly connected to the right side of the top end of the moving frame 1.

[0024] The fixing component includes a hydraulic push rod 14. The top end of the hydraulic push rod 14 is fixedly connected to the middle of the top inner wall of the moving frame 1. The driving end of the hydraulic push rod 14 is fixedly connected to a connecting rod 4. The front and rear sides of the outer wall of the connecting rod 4 are slidably connected to the inner wall of the moving frame 1. The left and right sides of the connecting rod 4 penetrate through the outer wall of the moving frame 1 and are fixedly connected to positioning plug boards 3. The opposite ends of the outer walls of the positioning plug boards 3 are slidably connected to the outer wall of the moving frame 1.

[0025] Traveling wheels 15 are installed at the four corners of the bottom end of the moving frame 1. The hydraulic push rod 14 is electrically connected to the controller 2.

[0026] The adjustment assembly includes a driving motor 18. The outer wall of the driving motor 18 is fixedly connected inside the right cavity of the inner wall of the horizontal adjustment frame 11. The front end of the right screw rod 17 penetrates through the inner wall of the horizontal adjustment frame 11 and is fixedly connected to the driving end of the driving motor 18. Pulley wheels are fixedly connected to the outer wall of the screw rod 17 near one side of the horizontal adjustment frame 11. The outer walls of the left and right pulley wheels are meshed and connected with a transmission belt 6. The left and right sides of the bottom outer wall of the sliding frame 7 are slidably connected inside the inner wall of the extension frame 8.

[0027] On the left and right sides of the top inner wall of the sliding frame 7, the same linear motor 10 is fixedly connected. The top inner wall of the distance measuring instrument 9 is fixedly connected to the outer wall of the driving end of the linear motor 10.

[0032] When this application is used, the moving frame 1 is moved to the edge of the test model to be measured or the edge of the water area to be measured through the traveling wheels 15. Then, the controller 2 controls the hydraulic push rod 14 to push the connecting rod 4 downward to slide inside the moving frame 1, so that the positioning plug board 3 is in close contact with the ground stably. If it is a mud surface, it is directly inserted into the mud, so that the position of the moving frame 1 is fixed. Then, by rotating the rotating wheel 5 to drive the threaded rod 13, the horizontal adjustment frame 11 slides left and right inside the moving frame 1 by a specified distance. The controller 2 controls the driving motor 18 to drive the right screw rod 17 to rotate, and at the same time drives the left screw rod 17 to rotate through the transmission belt 6 on the outside of the pulley wheel, so that the sliding frame 7 slides back and forth inside the inner wall of the extension frame 8 under the action of the screw rod 17, which is convenient for the device to measure at a position farther from the shore or the edge of the model. The controller 2 controls the linear motor 10 to drive the distance measuring instrument 9 to slide left and right on the top of the sliding frame 7, and under the control of the controller 2, the laser emitter 12 emits laser at a specified position to measure the elevation between the specified point on the water surface and the reference point, and the elevation average value of the water surface line is obtained by changing the position multiple times, thereby improving the measurement accuracy.

Any person skilled in the art within the technical scope disclosed by the present application, according to the technical solution of the present application and its application concept, making equivalent replacements or changes, shall be covered by the protection scope of the present application.
