Description

Technical Field

[0001] The utility model relates to the field of water conservancy detection, in particular to a drainage outlet flow rate detection device used for water conservancy detection. Background Art

[0002] At present, a Chinese utility model with a publication number of CN219036032U discloses an acoustic Doppler current meter, which belongs to the technical field of current meters. An acoustic Doppler current meter comprises a Doppler current meter body, a carrier plate is installed below the Doppler current meter body, a buoyancy box is symmetrically arranged at the edge of the lower surface of the carrier plate, a base is arranged below the carrier plate, and a sleeve is installed between the base and the carrier plate, a telescopic rod is movably connected to the top of the sleeve, a limit block is arranged at the bottom end of the telescopic rod, and the limit block is located on the inner side of the sleeve, so that the Doppler current meter body installed on the base floats on the water surface by utilizing the buoyancy box installed at the bottom edge of the carrier plate and the telescopic rod to cooperate with the sleeve to extend and retract, and at the same time, the detection end of the Doppler current meter body corresponds to the direction of water flow, so as to detect the flow velocity of the water body, so that the Doppler current meter body can be adjusted automatically according to the depth of different water bodies, thereby improving the applicability during detection.

[0003] Existing flow velocity detection equipment cannot be adjusted according to the size of the drain outlet. The Doppler flowmeter is generally installed at the outlet of the drain pipe to detect the water flow velocity. The size of the bracket of the general Doppler flowmeter is fixed and can only be used for water pipes of a specific size. If it needs to be used for drain pipes of different sizes, the bracket needs to be replaced, which increases the cost of use, reduces practicality and applicability, and is not convenient for installation and disassembly. The Doppler flowmeter and the bracket are generally fixed and installed by multiple bolts. When assembling and disassembling them, tools are required to disassemble and assemble them, which is cumbersome, increases workload, and reduces work efficiency. In order to solve the above-mentioned problems, we propose a drain outlet flow velocity detection device for water conservancy detection. Utility Model Content
