Problems solved by technology
The measurement of surface velocity is often carried out in different environments. In watersheds with relatively low water temperature, it has a great influence on the measurement results of flow velocity. The measurement of flow velocity needs to be performed at a specific temperature to achieve more accurate results, while the general surface velocity The sensor cannot effectively avoid the influence of temperature, and the error can only be reduced through data analysis and calculation, and the actual effect is not good

Embodiment Construction
[0019] The core of the present invention is to provide a surface flow velocity sensor, which can avoid the influence of water temperature on flow measurement results and obtain more accurate measurement data.
[0020] In order to enable those skilled in the art to better understand the technical solutions provided by the present invention, the surface flow velocity sensor of the present invention will be described in detail below with reference to the drawings and specific embodiments.
[0021] like figure 1 As shown, it is an exploded view of each component of the surface velocity sensor provided by the present invention. The device specifically includes a front shell 1, a heating device 2 and a rear shell 3, and the three are connected in fixed phases in turn. The front shell 1 is conical and is first in contact with the water flow. The streamlined structure can adapt to the water flow and avoid the impact on the water flow. The influence of the flow reduces the influence o...

The invention discloses a surface flow velocity sensor comprising a conical front shell, an annular heating device fixedly connected with the front shell, a filter net fixed between the front shell and the heating device, a rear shell fixed to the other end of the heating device, and a sensor fixed between the heating device and the rear shell. The conical front shell contacts water first, and the conical shape provides a streamlined design which adapts to the flow of water. The heating device, which is fixedly connected to the rear end of the front shell, has a very good heating effect on the water flowing through, and therefore, the water temperature needed by the sensor can be achieved. The filter net is fixedly arranged between the heating device and the front shell, and the filter net can filter the water entering the inside from the front shell to prevent impurities from blocking the sensor. The rear shell is arranged at the rear end of the heating device, and the sensor is arranged between the rear shell and the heating device. When the water flow heated by the heating device flows through the sensor, the temperature for normal work of the sensor is achieved.
Description
technical field [0001] The invention relates to the technical field of water flow velocity measurement, in particular to a surface flow velocity sensor. Background technique [0002] Among many hydrological indicators, the flow rate of river water is an important measurement data, which has important applications in monitoring river water flow, disaster prevention and mitigation, etc. The measurement of surface velocity is often carried out in different environments. In watersheds with relatively low water temperature, it has a great influence on the measurement results of flow velocity. The measurement of flow velocity needs to be performed at a specific temperature to achieve more accurate results, while the general surface velocity The sensor cannot effectively avoid the influence of temperature, and the error can only be reduced through data analysis and calculation, but the actual effect is not good. [0003] Therefore, for those skilled in the art, how to design a sur...
