Description

Technical Field

[0001] The utility model relates to the technical field of flow velocity detectors, in particular to a water flow velocity detector. Background Technique

[0002] Hydrological engineering includes hydrological analysis. The tasks of hydrological analysis and calculation are to estimate the hydrological situation during the long-term operation after the completion of the project and provide a basis for the planning and design of the project. The task of hydrological forecasting is to predict the water situation during the upcoming period and provide a basis for the construction, management and planned control and utilization of the project. Both of them are based on the historical hydrological conditions of the basin or region where they are located. Therefore, hydrological surveys and flood and low-flow investigations are also an important part of engineering hydrology work, and a propeller detector is required to detect the water flow velocity when carrying out hydrogeological engineering work.

[0003] The propeller detector is used to measure the time-average flow velocity at a predetermined measuring point in flowing water. The characteristics of this instrument are small volume, light and delicate shape, compact and precise structure, convenient to carry and use. It is suitable for small rivers, shallow beaches during the low-water period of large rivers, irrigation and drainage channels, water conservancy surveys, runoff experiments, etc., and is widely used in the pipe flow measurement for testing the efficiency of small and medium-sized pumping stations and the efficiency experiments of hydraulic machinery, as well as the sewage monitoring and seepage flow measurement by environmental protection departments.

[0004] When in use, the flow velocity detector is generally held by an operator with a operating rod, and then the propeller is put into the water to measure the water flow velocity. Although the basic purpose of detecting the water flow velocity can be achieved, due to the way of usually putting the hand-held detector into the water, the detector will constantly swing under the impact of the water flow, thus reducing the accuracy of the operator's detection of the water flow velocity. Therefore, a water flow velocity detector is proposed to solve the above problems. Content of the Utility Model

The other end of the body frame component is rotatably connected with a tail fin. One end of the body frame component is screwed with a first locking screw, and the first locking screw is in contact with the sleeve. The bottom end of the sleeve is rotatably connected with a support ring, and the support ring is fixedly connected with the measuring rod. A position adjusting mechanism is arranged at one end of the measuring rod, and a fixing mechanism is arranged at one end of the position adjusting mechanism.

A third locking screw is spirally connected to one end of the outer shell, and the other end of the third locking screw is in contact with the cross bar. A second locking screw is spirally connected to the other end of the outer shell, and the second locking screw is in contact with the vertical rod.

[0012] Preferably, scale lines are arranged on the outer side of the vertical rod.

[0013] Compared with the prior art, the utility model has the following beneficial effects:
