Description
Technical field
The utility model relates to a kind of measuring apparatus, particularly a kind of can fast measuring high concentration of sediment state under the channel water-carrying section fast measuring equipment of channel water-carrying section.
Background technology
Channel as the transporting water resource, water-carrying section is the basic foundation of metering water flow accurately, the physical dimension that channel is built---bottom width, slope are than size etc., generally be that design is determined with known, having only the water water level is dynamic change, as long as in real time, accurately measure height of water level, just can calculate discharge area and corresponding water flow.
At present, the method for conventional metering channel water level has following several: float gauge, pressure water level gauge, gas Jie ultrasonic water level gauge.
Float type level meter---traditional metering method, accurate measurement, stable and reliable for performance in clear water, but backward in technique, automaticity is low, generally must be placed in the stilling well of construction to use.If but use the high concentration of sediment water body, the silt of carrying secretly in the water, depositing will soon silt intake tunnel and stilling well up, causes and can't use, and has both made before silting up and can use several times, also its water level elevation can only be surveyed, but the mud height and the actual water level of channel can't be measured.
The pressure type water level gauge---be to measure water level because of different heights of water level induces corresponding hydraulic pressure, the pressure sensing work that partly sinks under water in case have mud to adhere to or buried by mud, causes and can't use.Equally, this instrument also can't be measured the mud height and the actual water level of channel.
The aerosphere type ultrasonic water level gauge---be with the level measuring instrument of air as acoustic-pulse propagation, its application mode is fixedly to uphang on the water surface, launch sound pulse and be received from the acoustical signal that water-reflected is returned to the water surface, by sound wave working time and sound velocimeter calculating height of water level.Shortcoming with aforementioned two kinds of methods is the same, can only measure water level elevation and can't measure silting height at the bottom of the canal, can't the true water-carrying section of reflection channel.
Therefore, above-mentioned general water level measuring products and method are feasible limpid the change under the canal cross sections state of water body, but in the canal for water conveyance of high sediment charge, owing to can precipitating silt gradually in course of conveying, the channel water body deposits, the bottom width and the end height of channel have been changed, simple water level metering can't truly reflect the discharge area, because the water level instrument that the silt alluvial causes loses application function.
Summary of the invention
The purpose of the utility model embodiment is the defective at above-mentioned prior art, and a kind of channel water-carrying section fast measuring equipment is provided, can be truly, fast measuring channel water-carrying section effectively, can dynamically measure two indexs of water level and mud.
The technical scheme taked of the utility model embodiment is to achieve these goals: a kind of channel water-carrying section fast measuring equipment, across on channel, comprise the aqueous medium ultrasonic transducer, propulsion system, track across described channel, wherein, track is placed on described channel both sides embankment and gets on the right track and shelve on the seat, described propulsion system inside is provided with the aqueous medium ultrasonic measurement system, described aqueous medium ultrasonic measurement system can make described propulsion system to do level and vertical movement by described relatively track, described aqueous medium ultrasonic transducer is assemblied in the guiding device, and described guiding device is drawn by described propulsion system.
For the accuracy that guarantees to measure, it is contour with described canal top that described track is shelved seat.
As preferably, described guiding device is a fish lead.
In order to reach the real effectiveness of measurement, the aqueous medium ultrasonic measurement system in the described propulsion system comprises that also control aqueous medium ultrasonic transducer touches the self-con-tained unit that water promptly stops.
The utility model uses the propulsion system of measurable range ability that the aqueous medium ultrasonic transducer is reduced to the water surface from fixed starting-point; The self-induction signal that touches water of aqueous medium ultrasonic transducer is input to the power control system of propulsion system, and the ultrasonic transducer entry is promptly stopped, and measures and export the distance of the water surface to water-bed alluvial face simultaneously.Immediately, the system-computed unit calculates former total elevation given data of having measured and power range ability and ultrasonic water level gauge measuring distance, just can draw the elevation of the husky alluvial of real-time actual water level elevation of certain measuring point and canal bed mud simultaneously; Propulsion system make the displacement of ultrasonic transducer along continuous straight runs and carry out point-to-point measurement, form water-bed elevation curve, in view of the above, can truly measure and reflect the channel discharge section area.
The beneficial effect of the utility model embodiment is: compared to existing technology, the utility model can be truly, fast measuring channel water-carrying section effectively, can dynamically measure two indexs of water level and mud, especially be fit to the quick measurement of channel water-carrying section under the high concentration of sediment state.
