Problems solved by technology

[0007] Aiming at the deficiencies of the prior art, the present invention provides a new type of flow velocity detector for water conservancy measurement, which overcomes the deficiencies of the prior art, has a reasonable design and a compact structure, and aims to solve the problem that the existing flow velocity detectors are single-pass sensors. Detecting the flow rate of water takes a long time to respond, and the data is not accurate; at the same time, there is no comparison data, and the results cannot be applied to the problem of water conservancy construction

Embodiment 1

[0035] A new type of flow rate detector for water conservancy measurement, comprising a horizontally arranged frame 1, four electric telescopic legs 2 are fixedly installed on the lower end edge of the frame 1, and fixing nails are fixedly installed on the telescopic ends of the electric telescopic legs 2 Plate 3 is used to extend the electric telescopic legs 2 downward when the detector enters the water, and locate the fixed nail plate 3 on the bottom of the water, so as to realize accurate measurement. The lower end of the frame 1 is provided with a flow velocity measurement mechanism 4 and a flow velocity correction mechanism 5 The flow velocity measuring mechanism 4 is used to measure the water flow velocity in the river channel or the canal, and the flow velocity correction mechanism 5 is used to assist measurement and give data, and to calibrate in combination with the flow velocity of the flow velocity measuring mechanism 4, so as to ensure accurate measurement;

Embodiment 2

[0043] The difference between this embodiment and embodiment 1 is that, as image 3 As shown, the upper end of the drive shaft 42 is covered with a lifting plate 43, and the upper edge of the lifting plate 43 is connected with the lower plate 45 through a plurality of oil cylinders 44, through the synchronous start and stop of a plurality of oil cylinders 44, the liquid level adjustment can be realized. The detection of water flow velocity at different liquid levels can meet the needs of water conservancy measurement.

[0044] In this example, if image 3 As shown, a plurality of the oil cylinders 44 are distributed in an annular array, and the number of the oil cylinders 44 is more than or equal to three, effectively ensuring the movement of the rotating impeller 41 and the plastic moving block 51. At the same time, the annular arrangement of the oil cylinders 44 can effectively Ensure the positioning of the drive shaft 42 and the sleeve shaft 46, and the protection device w...

Abstract

The invention relates to the technical field of water conservancy measurement, provides a novel flow velocity detector for water conservancy measurement, and aims to solve problems that the existing flow velocity detector only detects the flow velocity of water through an inductor, the reaction time is long, and the data is not accurate. The detector is characterized by comprising a horizontally-arranged rack, four electric telescopic legs are fixedly installed on an edge of a lower end of the rack, fixing nail plates are fixedly installed at telescopic ends of the electric telescopic legs, and a flow velocity measuring mechanism and a flow velocity correcting mechanism are arranged at the lower end of the rack; the flow velocity measuring mechanism comprises a rotating impeller horizontally arranged in the middle of the lower end of the rack, a driving shaft is installed in the middle of the rotating impeller, a spline shaft is integrally formed at the upper end of the driving shaft,and the spline shaft is inserted into an inner cavity of the sleeve shaft. The detector is especially suitable for flow velocity measurement of water conservancy construction, and has high social usevalue and application prospect.

Description

technical field [0001] The invention relates to the technical field of water conservancy measurement, in particular to a novel flow velocity detector for water conservancy measurement. Background technique [0002] The term water conservancy was first seen in the chapter "Filial Piety and Caution for People" in "Lu Shi Chunqiu" published at the end of the Warring States period, but the "water conservancy" it talks about refers to the benefits of fishing. Due to the continuous development of modern society, economy and technology, the connotation of water conservancy is also constantly enriched and expanded. In 1933, the resolution of the third annual meeting of the Chinese Hydraulic Engineering Society clearly pointed out: "The scope of water conservancy should include flood control, drainage, irrigation, water power, waterways, etc. , water supply, sewage drains, and port engineering projects." [0003] The term water conservancy can be summarized as: human society takes v...
