Description

Technical Field

[0001] The utility model belongs to the technical field of water body flow velocity detection, in particular to a propeller type flow meter used for water body flow velocity detection. Background Art

[0002] A propeller current meter is a device used to measure the flow rate of water. It usually consists of a rotating blade or spiral structure installed on a buoy or fixed bracket. It measures the speed of the water flow through the rotational motion. When the water flows through the propeller, the rotation speed is proportional to the water flow speed.

[0003] The function of a propeller flow meter is to measure flow velocity in water bodies, which is very important in fields such as hydrology, environmental monitoring, and water conservancy project design. By understanding the water flow velocity, it can help predict flood conditions, design dams, hydropower stations, and other water conservancy facilities. It can also evaluate the hydrodynamic processes in rivers, lakes, or oceans, which is of great significance to water resources management and environmental protection.

[0004] The propeller flowmeter currently used for water flow velocity detection can adjust the operating height, but it needs to be adjusted in advance and then placed in running water. When you want to adjust the operating height, you can only take it out and adjust it. This easily increases the workload of detection and is cumbersome to use.

[0005] To this end, we provide a propeller flow meter for water flow velocity detection to solve the above problems. Utility Model Content
