A portable water flow rate measuring device for water conservancy detection

Abstract

The invention discloses a portable water flow rate measuring device for water conservancy detection, which comprises a water flow rate measuring instrument, a conical counterweight is arranged under the water flow rate measuring instrument, and a conical counterweight is fixedly installed on the top of the conical counterweight. Cover plate, the top of the conical counterweight is provided with a rectangular hole, the bottom of the water flow rate measuring instrument is fixedly connected with a fixed seat, and the bottom of the fixed seat extends into the rectangular hole, the cover plate is fixedly sleeved on the fixed seat, and the rectangular hole The inner sealing sliding sleeve is provided with a rectangular box with an opening at the top. The design of the invention is reasonable, and the setting of four auger ground blades facilitates screwing into the river bottom after being lowered into the water, so as to achieve the effect of being rooted in the river bottom, effectively reducing the risk of being washed away or knocked down by the river, and improving the stability of the measurement , and after use, it is convenient to store the four auger ground leaves in the rectangular hole, avoiding the phenomenon of being stabbed or broken when it is exposed outside when carrying or not in use, which is beneficial to use.

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 use, and it is easy to find or not find the stones and stones on site during use. In some Clean places require labor and time for workers to find, and they also have the disadvantage of low stability after being lowered into the water. There is a greater risk of being shaken, displaced and dumped by the water flow, which cannot meet the needs of use. Therefore, we propose a water conservancy inspection. Portable water velocity measurement device is used to solve the above problems
