Detailed Implementation

[0020] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0021] like Figures 1-4 As shown, this utility model provides a water depth measuring device for hydraulic engineering, including a base 1. A column 2 is fixedly mounted on the base 1, and an L-shaped extension column 3 is fixedly mounted on the top of the column 2. A translation motor 4 is mounted above the extension column 3, and the output end of the translation motor 4 is connected to a translation screw 5. The other end of the translation screw 5 is rotatably connected to the column 2, and a guide groove 31 is provided on the extension column 3 along its length. A movable plate 6 is threadedly connected to the translation screw 5, and one end of the movable plate 6 is provided with a rotatable guide wheel 18. The guide wheel 18 is designed to be embedded in the guide groove 31 and slide therein. This design can further improve the stability of the movable plate 6 on the extension column 3, prevent it from shaking, and thus improve the measurement accuracy. The movable plate 6 integrates the core measurement and protection functions of this utility model, namely the wave-damping component 7. Multiple casters 19 are installed under the base 1 to facilitate the movement of the device on the ground or platform. A push rod 20 is fixedly mounted on one side of the base 1 to assist in pushing the device.

[0022] The wave-damping assembly 7 includes a lifting motor 71, a driving bevel gear 72, a driven bevel gear 73, a lifting screw 74, and a wave-damping cover 75. The lifting motor 71 is fixedly mounted on the upper surface of the movable plate 6. The output shaft of the lifting motor 71 is connected to the driving bevel gear 72. The lifting screw 74 is vertically positioned, passing through the movable plate 6, and its top end is connected to the driving bevel gear 72. The driven bevel gear 73 is connected to the bottom of the movable plate 6 and meshes with the driving bevel gear 72. The threaded portion of the lifting screw 74 mates with a threaded hole inside the wave-damping cover 75. At the bottom of the movable plate 6, two guide rods 9 are also provided, parallel and symmetrically distributed with the lifting screw 74. The top of the wave-damping cover 75 is fitted onto the guide rods 9 and is raised and lowered by a threaded connection with the lifting screw 74. To improve the wave-damping effect, two layers of annular baffles 751 are coaxially arranged on the inner side of the wave-damping cover 75. These two layers of annular baffles 751 further block water waves. To facilitate water flow, the bottom of the wave shield 75 and the annular baffle 751 are provided with multiple staggered buffer openings 752, which reduce water wave interference while allowing a certain amount of water to pass through. The bottom ends of the lifting screw 74 and the guide rod 9 are provided with limit blocks 17 to provide protection and positioning when the lifting is at the lowest point.

[0023] A through hole 61 is provided in the middle of the movable plate 6 for the traction rope 14 to pass through. A rotatable guide pulley 10 is provided above the through hole 61, and the traction rope 14 passes over the guide pulley 10 and enters the through hole 61. Support frames 11 are fixedly provided on both sides of the upper end of the column 2. A rotary motor 12 is installed on one of the support frames 11, and its output end is connected to a take-up roller 13. The take-up roller 13 is installed between the two support frames 11, allowing it to rotate freely. A certain length of traction rope 14 is wound on the take-up roller 13. One end of the traction rope 14 is led out from the take-up roller 13, passes over the guide pulley 10, passes through the through hole 61 of the movable plate 6, and its end is connected to a counterweight 15. The weight of the counterweight 15 ensures the tension of the traction rope 14 and can drive the liquid level sensor 16 to sink. The liquid level sensor 16 is installed on the counterweight 15, and the water depth is determined by the liquid level sensor 16.

[0024] The translation motor 4, lifting motor 71, rotary motor 12, and liquid level sensor 16 are all electrically connected to the control board 8. The control board 8, as the control core of the entire device, receives sensor data and controls the operation of each motor according to a preset program to achieve automated measurement.

[0025] Working principle:

[0026] The operator moves the measuring device to the area to be measured using the casters 19 and push rod 20 on the base 1. Upon receiving the command, the control board 8 activates the translation motor 4. The translation motor 4, via the translation screw 5, drives the movable plate 6 connected to it to move horizontally along a preset path on the L-shaped extension column 3. This allows for the measurement of water depth at different lateral positions.

[0027] During this process, the control board 8 can also adjust the height of the wave deflector 75 as needed by driving the lifting screw 74 through the lifting motor 71. The lifting screw 74 obtains power through the meshing of the driving bevel gear 72 and the driven bevel gear 73, and the guide rod 9 ensures the stable lifting and lowering of the wave deflector 75. The wave deflector 75 and its internal annular baffle 751 and buffer port 752 can effectively reduce the interference of water waves and currents on the measurement process.

[0028] Once the moving plate 6 reaches the target measurement position, the control board 8 begins to control the rotary motor 12. The rotary motor 12 drives the traction rope 14 on the take-up roller 13 to gradually loosen. One end of the traction rope 14 is connected to a counterweight 15, on which a liquid level sensor 16 is mounted. As the traction rope 14 is lowered, the counterweight 15 and the liquid level sensor 16 sink into the water together. The traction rope 14 first passes around the guide pulley 10 on the moving plate 6, then through the through hole 61 in the middle of the moving plate 6, and finally connects to the counterweight 15. The guide pulley 10 ensures the smooth lowering of the traction rope 14.

[0029] During its descent, the liquid level sensor 16 monitors the water depth in real time. When the liquid level sensor 16 touches the bottom or reaches the preset minimum water depth, the control board 8 receives a sensor signal. The water depth at the current measurement point can be accurately calculated from the reading of the liquid level sensor 16 (usually the depth from the water surface).
