Description

Anti-floating object counterweight flow velocity sensor Technical Field The utility model relates to the technical field of hydraulic engineering, in particular to an anti-floating object counterweight flow velocity sensor. Background In the field of hydraulic engineering, a counter weight flow rate sensor is generally required to monitor the flow rate of water flow under the water surface, the water surface is firstly required to be divided into a plurality of sections, the counter weight flow rate sensor is placed on each section, the flow rates measured by the sections are counted, and then the average flow rate of the whole water surface is calculated. Most of the flow rate sensors are thrown into water manually, but buoyancy in water or sundries such as algae tend to block sinking of the flow rate sensors, so that the flow rate sensors float on the water surface and are difficult to effectively submerge. Therefore, the anti-floating object counterweight flow velocity sensor is provided, so that a counterweight baffle frame capable of blocking sundries such as algae can be conveniently arranged, the flow velocity sensor can be smoothly submerged in water, and the accuracy of a measurement result is improved. Disclosure of utility model Aiming at the problems in the prior art, the utility model provides the anti-floating counterweight flow velocity sensor which is convenient for arranging the counterweight baffle frame capable of blocking sundries such as algae and the like, so that the flow velocity sensor is smoothly immersed in water, and the accuracy of a measurement result is improved.
