[0001] The present invention relates to the technical field of water conservancy flow measurement equipment, in particular to a flow measurement device for water conservancy geological survey and a use method thereof. Background Art

[0002] Hydrogeological survey refers to the process of conducting detailed investigations and surveys of the geological characteristics, geological structure, groundwater conditions, and geological hazards of the project area before the construction of a water conservancy project. Through hydrogeological surveys, project planners and designers can understand the geological conditions of the project area, providing the necessary basic geological data and information for the site selection, design, and construction of water conservancy projects. There are various types of equipment used to measure water flow, including radar flowmeters, Doppler flowmeters, and ultrasonic open channel flowmeters. To facilitate the measurement of water flow in a watershed, it is usually necessary to install the flowmeter on the bank of the watershed with a special mounting bracket and measure the water flow through the flowmeter.

[0003] However, existing flowmeters for hydraulic surveys present the following challenges: Before installing the flowmeter, a foundation pit must be dug at the installation location and the mounting frame must be buried and fixed to the shore to ensure stability. However, this approach makes it difficult to relocate the mounting frame as needed. Furthermore, the mounting frame is located at a considerable height, requiring manual retrieval or removal of the mounting frame to inspect and replace the flowmeter. Consequently, a corresponding technical solution is needed to address these challenges. Summary of the Invention

[0016] When the support frame needs to be installed, the staff will open a foundation pit at the installation location in advance. The depth of the foundation pit is controlled at 0.8m-1m. Then the staff will insert the split landfill base into the foundation pit and pour water into the main tube. The handheld rocker will drive the floating mounting seat to move downward. During the downward movement, the floating column will move downward synchronously and resist the moving rod and the hollow insert plate to move outward. During the outward movement, the hollow insert plate will be inserted into the soil and the floating limit column will extend.

The support frame is then inserted into the split landfill base, and the automatic tractor climbs along the support frame and moves the flow meter to the end of the support frame. At the same time, the photovoltaic charging component converts solar energy into electrical energy and provides partial power for the flow meter. When the flow measuring equipment needs to be towed, the support frame is detached and the split landfill base is quickly taken out.

During the outward movement, the hollow inserter 23 will be inserted into the soil and the floating limit column 26 will be extended. At the same time, the water will flow along the diversion cavity 27 and be discharged from the drainage channel 28 to moisten the soil, making it easier for the hollow inserter 23 to be inserted into the soil, thereby achieving the purpose of fixed installation of the split landfill base. After the installation is completed, the lower end of the support frame will be inserted into the socket 36 to complete the installation of the support frame, and then the motor 18 will be driven The dynamic driving gear 17 rotates, and the driving gear 17 moves along the guide groove 19 and climbs to the end of the support frame to complete the position adjustment of the flow meter 1.
