Abstract
The invention discloses a device for moving an entrained air concentration meter sensor. The device is characterized by comprising a fixing device, a base and a support, wherein the fixing device is arranged on the base through a bolt; the base is provided with a sliding groove and the support; two sides of the base are provided with two bolts respectively; the support is used for supporting a conducting wire which is connected with the entrained air concentration meter sensor; the fixing device can transversely move on the sliding groove and is a square clamping groove; the clamping groove is used for fixing the entrained air concentration meter sensor; and the entrained air concentration meter sensor can be adjusted to move longitudinally on a water tank or fixed through the bolts on two sides of the base. The device is easy to operate, can be flexibly adjusted, and can adjust the entrained air concentration meter sensor to move transversely or longitudinally on the water tank or fix the entrained air concentration meter sensor, accurately fix the entrained air concentration meter sensor at an appointed position of the water tank, and prevent the error caused by the jitter of the sensor.
Description
Technical field
The present invention relates to a kind of novel aeration concentrater appearance sensor mobile device that is applied to hydraulic experiment chamber tank aeration concentrater mensuration.
Background technology
When the high water head outlet structure escape works were crossed water, because head is high, flow velocity was big, and regular meeting has a large amount of air to mix in the current under certain condition, formed milky gas-vapor mix stream, and this current are called aerated flow.The aeration phenomenon of high-velocity flow generally betides in the outlet structure escape works such as high speed chute, overfall dam, open channel flood discharging tunnel, gate slot.Aerated flow has increased the pulsation and the vibration of current, the safety of serious threat outlet structure escape works on the one hand; But can reduce or remit the destruction of cavitation corrosion on the other hand, alleviate current washing away outlet structure escape works and underwater bed.Therefore, the hydraulic performance of research aerated flow has important directive significance to design, operation and the management of high water head outlet structure escape works.The hydraulic performance of aerated flow is relevant with its aeration concentrater, and aeration concentrater (representing with C) is the ratio that the volume of gas accounts for the volume of gas-vapor mix body in the aerated flow, may be defined as:
Qa in the formula, Qw are respectively gas flow and discharge.
When studying the high-velocity flow aeration, adopt the aeration concentrater appearance to measure the aeration concentrater of current usually in the hydraulic experiment chamber.The aeration concentrater appearance mainly is made up of sensor, main frame and lead, can measure the aeration concentrater of any degree of depth in the tank simply.
Because producer does not provide and the supporting mobile device of aeration concentrater appearance sensor; Measure in the tank aeration concentrater with the aeration concentrater appearance in the laboratory very inconvenient; Often through manual work fixing aeration concentrater appearance sensor simply; It is cumbersome that fixing on the one hand back changes the position, and simple fixation is stable very poor on the other hand, has shake then can influence measurement slightly.
Summary of the invention
For overcoming not convenience of the operation that aeration concentrater occurred that the aeration concentrater appearance measures current in the tank; Improve the accuracy of determination data, the present invention proposes a kind of novel aeration concentrater appearance sensor mobile device that is applied to hydraulic experiment chamber tank aeration concentrater mensuration.
The technical scheme that the present invention adopts is: aeration concentrater appearance sensor mobile device; It is characterized in that: comprise stationary installation, base and support, described stationary installation is installed on the said base through bolt, and said base is provided with chute and support; Two bolts respectively are equipped with in both sides; Said support is used for the lead of support and connection aeration concentrater appearance sensor, and said stationary installation can move laterally on said chute, and described stationary installation is square draw-in groove; Said draw-in groove is used for fixing aeration concentrater appearance sensor, can regulate that aeration concentrater appearance sensor vertically moves or fixing on tank through the bolt of said base both sides.
Beneficial effect of the present invention is embodied in: easy and simple to handle, regulate flexibly; Can regulate aeration concentrater appearance sensor does on tank laterally and vertically moves or fixing; Accurately aeration concentrater appearance sensor is fixed on the assigned address of tank, and prevents the error that the sensor shake causes.
