Portable water flow velocity measuring device for water conservancy detection

Abstract

The invention discloses a portable water flow velocity measuring device for water conservancy detection. The device comprises a water flow velocity measuring instrument, a conical balancing weight isarranged below the water flow velocity measuring instrument; a cover plate is fixedly installed at the top of the conical balancing weight, a rectangular hole is formed in the top of the conical balancing weight, a fixing base is fixedly connected to the bottom of the water flow velocity measuring instrument, the bottom of the fixing base extends into the rectangular hole, the cover plate is fixedly arranged on the fixing base in a sleeving mode, and a rectangular box with an opening in the top is arranged in the rectangular hole in a sealed sliding and sleeving mode. The design is reasonable,four spiral drilling blades are arranged; the device is convenient to screw into a river bottom after being put into water, the effect of rooting at the river bottom is achieved, the risk of being flushed away or flushed down by a river is effectively reduced, the stability during the measurement is improved, the four spiral drill ground blades are conveniently stored into the rectangular hole after being used, the phenomenon that people are stabbed or the spiral drill ground blades are broken due to exposure when the spiral drill ground blades are carried or not used is avoided, and the useof the device is facilitated.

Description

technical field [0001] The invention relates to the technical field of water flow velocity measurement equipment, in particular to a portable water flow velocity measurement device for water conservancy testing. Background technique [0002] The principle of water flow measurement is to use a water velocity measuring instrument to measure the speed of the water flow, and then convert the flow rate of the water according to the water flow speed, which can quickly measure the flow, measure the average horizontal flow velocity of the river according to the induction of the measuring rod to the water flow, and then pass the measuring rod The upper sensor transmits the data to the instrument, and the instrument panel calculates the water flow velocity in this section through calculation. The state of the water flow is not easy to accumulate sludge, and the water flow rate is also a very important indicator in the water conservancy inspection. The authorized announcement number CN...

Problems solved by technology

[0003] Although the above-mentioned patent prevents the current meter from being washed away and lost by stuffing stones inside the device, the way of lowering it into the water as a whole does not require some supporting equipment such as external brackets, and it is convenient to carry; but this method needs to be used every time. When the device is filled with stones, and the stones are placed in the river when taken out, a large amount of stones will be lost after repeated...
