Description

Technical Field

[0001] The utility model relates to the technical field of water level flow monitoring equipment, and specifically to a positioning and regulating device for radar water level flow monitoring equipment. Background Art

[0002] The water level flow detection equipment is an integrated non-contact monitoring device for flow velocity, water level and flow. It applies radar planar microwave technology and uses the Doppler radar principle to calculate the average flow velocity of the water flow by measuring the difference between the incident wave and the reflected wave frequency on the water surface. Then, by presetting different water flow cross-sectional shapes, it combines the area empirical formula and the hydraulic model algorithm to calculate the flow rate. In order to improve the accuracy of the difference between the radar incident frequency and the reflected frequency, it is necessary to adjust the angle between the water level flow probe that transmits the radar wave and the water surface during the installation process to ensure that the radar receiving antenna can effectively receive the radar wave reflected from the water surface.

[0003] During the actual operation, it was found that since the water level flow probe needs to be installed on a horizontal arm above the water surface, the manual adjustment of the angle requires the cooperation of large equipment such as cranes, which is not only difficult to ensure accuracy but also involves certain risks.
