Description
Technical field
The present invention relates to the hydrology and geology correlative technology field, specifically, relate to a kind of irregular section flow measurement dress
Put and measuring method.
Background technology
China's water resource is enriched, and carries out one of the important content that water flow measurement is survey for the purpose of locating hydrogeological resources.
During common irregular section channel flow measurement, installation tank weir on channel, the size of flow in channel is turned
It is changed to the height of liquid level, by the liquid level in liquidometer measuring flume weir, by flow converter, according to the liquid level on all kinds of groove weirs
Discharge relation calculates the flow of liquid.
Under field conditions (factors), open channel size differs, and need to select groove weir, and flume weir according to situ flow weight range size
Make, carry, installation inconvenience.Meanwhile, triangular-notch weir, rectangular weir, wide weir are relatively big to the resistance of current, solids
It is prone to be deposited on upstream.And the shortcomings such as Baxeer slot, cut_throat flume weir cost of manufacture height.
In prior art, there is part about cross-section of river stream quantifier elimination.Such as Application No. 201310181539.7
Chinese patent literature provide a kind of flow velocity self-correcting open channel flow rate measurement apparatus, specifically include that base, be provided with
Drive motor, flow velocity transmitter and lower end to pass the vertical tub of base, vertical tub is provided with by driving motor-driven
Elevating mechanism；Liquid level sensor I, is arranged on base；Connecting rod, is enclosed within vertical tub, and its upper end is with elevating mechanism even
Connecing, vertical tub is extended in lower end；Flow sensor, is connected to the lower end of connecting rod, and electrically connects with flow velocity transmitter；Liquid
Level sensor II, is arranged on flow sensor, is used for detecting flow sensor in the subsurface degree of depth；And TT&C system.
The program by steel wire rope drive flow sensor lift, during lifting between signal in real time return to control system
System, and according to the depth signal of liquid level sensor II feedback, flow sensor is corrected the mean flow rate point to section, final root
According to the height of water level value detected and flow speed value and tested open channel sizecalculation outflow value.
But, there is more defect in the program, specifically includes:
1, being limited to self structure, during it uses, base must be fixedly arranged at the object (such as surveying vessel) floating on river surface
On.Meanwhile, steel wire rope is utilized to drive Diffuse Coptosapelta sensor to rise.But, during measuring, surveying vessel is cannot be relative
The most stable in water-bed holding position, because of the reason of current and wind, a certain degree of displacement will necessarily occur.Another factor is,
Steel wire rope substantially has certain flexibility and wilful rope, and during flow sensor rises, it is necessarily by current
, there is certain deformation in thrust.For the current of differing heights, its flow velocity is the most different.
Based on above-mentioned multiple factors effect, can cause flow sensor movement locus during rising is irregular curve,
Make the flow velocity signal collected there are differences with actual signal, affect the process of follow-up data.
2, the calculating of the cross-section of river, not only relevant with flow velocity, also relevant with the area of the cross-section of river.The program is only capable of measurement
The flow velocity of cross-section of river water, based on existing formula and the physical dimension of known measured open channel thus calculate flow value.
But, when measured object is irregular section, the area of the cross-section of river just cannot be known so that this device is basic
Cannot use.
Therefore, it is necessary to design a kind of device with relatively high universalizable, realize the measurement to various section flows.
