Technical Field

[0002] Water conservancy survey is an important part of water conservancy project design and construction. It includes investigation, measurement and analysis of natural conditions such as topography, geology, hydrology, and meteorology of water conservancy projects to obtain necessary data and information, and provide scientific basis for the design and construction of water conservancy projects. Water level measurement usually requires the use of water level gauges. There are many existing measurement methods. Different water level gauges are required according to different hydrological conditions. The existing water level gauges include radar water level gauges, float water level gauges, pressure water level gauges and ultrasonic water level gauges. Ultrasonic water level gauges are non-contact, highly reliable, cost-effective, and easy to install and maintain level measuring instruments. It can meet most level measurement requirements without contacting the medium. The ultrasonic pulse emitted by the transmitting ultrasonic transducer is transmitted to the surface of the object to be measured through the transmission medium, and then returned to the receiving transducer through the sound transmission medium after reflection, and the time of ultrasonic pulse propagation from emission to reception in the sound transmission medium is measured. However, the existing ultrasonic water level gauge is not convenient for replacing the position of the ultrasonic water level gauge during use, which reduces the convenience of subsequent maintenance of the ultrasonic water level gauge.

The gear 46 is driven, and the hand crank 11 is rotated to drive the storage box 2 to rotate through the worm gear reducer 12, the sun gear 13, the planetary gear 14 and the inner ring gear 15. The driving motor 2 44 drives the rack 43 to slide along the slide groove through the worm gear reducer 2 45 and the driving gear 46. The rack 43 and the telescopic rod 41 extend from the inside of the telescopic sleeve 4. The ultrasonic probe 24 cooperates with the ultrasonic host 22 to detect the water level. In this way, the position of the ultrasonic water level meter can be conveniently and quickly adjusted, which is convenient for subsequent maintenance. A bearing is installed at the connection between the storage box 2 and the device base 1, and the storage box 2 and the device base 1 are arranged to coincide with the center line. The bearing can make the storage box 2 reliable and stable under the drive of the hand crank 11. The rotation of the storage box 2 is more reliable and stable. The data transmission line 23 is wound around the outer side of the winding roller 31, and the winding roller 31 and the device base 1 are arranged in parallel with each other. When the drive motor 3 drives the winding roller 31 to rotate, the data transmission line 23 wound around the outer side of the winding roller 31 can be wound.

At this time, the hand crank 11 is rotated to drive the worm gear reducer 12 to rotate, and then the power is transmitted to the sun gear 13. The sun gear 13 transmits the power to the inner ring 15 through the planetary gear 14. The inner ring 15 drives the storage box 2 to rotate, and the telescopic sleeve 4 and the mounting block 42 are rotated to the water surface. At this time, the driving motor 2 44 drives the driving gear 46 to rotate through the worm gear reducer 2 45, and the driving gear 46 drives the rack 43 to slide along the slide groove, thereby adjusting the position of the mounting block 42. During the adjustment, the driving motor 13 drives the winding roller 31 to rotate to transmit the data transmission line 23. Quantitative release is carried out to ensure that the data transmission line 23 is neatly rolled up. After the adjustment is completed, the ultrasonic probe 24 detects the water level and transmits the data to the ultrasonic host 22. After measuring one point, the hand crank 11 drives the storage box 2 to rotate, and the driving motor 2 44 drives the telescopic rod 41 and the mounting block 42 to extend or retract, so that the water level of a fan-shaped area on the water surface can be measured. In this way, the position of the ultrasonic water level meter can be conveniently and quickly adjusted, which is convenient for subsequent maintenance. After the measurement is completed, the hand crank 11 drives the storage box 2 to rotate, and the mounting block 42 reaches the ground position. At this time, the operator can replace and adjust the ultrasonic probe 24. In this way, the replacement and adjustment of the ultrasonic probe 24 can be convenient.
