Description

A propeller type current meter fixing frame

technical field

The utility model relates to a tool for measuring flow velocity in a hydraulic test, in particular to a fixed frame of a propeller type flow velocity meter.

Background technique

In hydraulic tests, flow velocity is a very important indicator. At present, there are many instruments for measuring flow velocity in hydraulic tests, but the propeller type flow meter is an instrument with relatively high measurement accuracy and easy operation. However, there is not yet a suitable propeller-type flow meter fixing frame at present, and it is usually manually fixed for hydraulic test flow velocity measurement. One is to manually hold the propeller type flow meter for measurement, which requires the propeller type flow meter to be placed at each measuring point of each section of the laboratory tank, which is not only time-consuming and laborious, but also has low measurement efficiency; the second is to measure the flow rate in the hydraulic laboratory. To obtain more reasonable data, multiple measurements are required, so that the propeller flowmeter needs to be continuously switched between the horizontal and vertical positions of the space. If it is manually operated, it will lead to inaccurate measurement data and affect the experiment. Effect.

The utility model is a fixed frame of a propeller-type current meter, which has the following technical effects:

1) By setting mutually perpendicular supports and rotating screws, the rotary flow meter can be guaranteed to move in the horizontal position, and can also move in the vertical direction at the same time, so as to achieve the purpose of accurately measuring the cross-sectional flow velocity in the hydraulic laboratory, so that It can be operated without manual hand-holding and fixing, which is convenient and fast to measure, reduces the labor workload of measuring personnel, improves labor efficiency, and reduces costs.

2) By setting the vertical scale scale on both sides of the vertical support and the horizontal scale scale on the rectangular side of the rotating screw, the spatial position of the propeller flowmeter can be adjusted up and down, left and right, which not only meets the requirements of hydraulic tests. Cross-sectional velocity measurement space requirements, while making the measurement data more accurate, improving the accuracy and accuracy of the test.

3) In the past, when the hydraulic laboratory used the propeller-type flowmeter to measure, someone needed to fix the flowmeter, someone to move the support, and someone to observe the flowmeter, and this propeller-type flowmeter fixed frame just solved such problems. It only needs one person to operate, which simplifies the equipment operation process.

4) Simple structure, easy to install, disassemble and carry, convenient for laboratory operation.

detailed description

As shown in Figure 1-2, a propeller-type current meter fixing frame includes a vertical support 1, and the bottom of the vertical support 1 is a triangular bracket for convenient placement on both sides of the laboratory sink. Sliding on the two vertical bearings 1 is provided with a rectangular slider 9, between the two rectangular sliders 9, a rotating screw 2 and a slide bar 3 are arranged, and the rotating screw 2 drives the circumferential rotation through the rotating wheel, and the slide bar 3 Then be fixed between two rectangular slide blocks 9. By adjusting the slide block 9, the rotating screw 2 and the slide bar 3 can be moved up and down, and when they are moved to a certain position, they are locked by the friction of the fixing bolt 4. The moving carriage 5 is provided with a threaded hole and a square through hole, and the moving carriage 5 passes through the threaded hole and the square through hole to pass through the rotating screw 2 and the slide bar 3 respectively. The slide frame 5 is positioned and moved left and right. The propeller type flow meter 7 is installed on the lock ring 6 of the mobile carriage 5 and locked. There is a propeller probe at the bottom of the propeller type flow meter and a connecting device at the top. Instrument connection.
