Abstract
The utility model relates to a non-contact tidal current measuring device. The dynamic range measured by the conventional current meter is too narrow. The utility model comprises a radar electric wave current-meter; wherein, the radar electric wave current-meter is fixed on a holder with a tripod, and pins of the holder are arranged on an under-bridge extension section. An adjusting rod which can adjust the holder surface in upper, lower, left, and right directions is arranged on the holder, so that the electric wave current-meter is aligned with the water flow direction, and an included angle between the electric wave current-meter and the river surface A is less than 45 degrees. The under-bridge extension section and the bridge bottom are in rigid connection; an output interface of the radar electric wave current-meter is directly input in a signal box which is placed at a pier protrusion; and a tidal indicator light is arranged on the top of the signal box, and a remote output interface is arranged at the bottom of the signal box. By adopting wide-range and non-contact radar electric wave current-meter measurement method, the utility model realizes tidal flow velocity and direction measurement during tidal surge. The utility model has the advantages of simple structure, installation, and low maintenance cost.
Description
Technical field
The utility model belongs to the automatic control technology field, relates to a kind of non-contact measurement apparatus of tide current flow speed and direction.
Background technology
The dynamic range of integrated in the market flow rate and direction instrumentation amount is too little, generally can only reach 0 to 5 meter per second.And on a large scale velocimeter (0.1 to 12 meter per second) can only measurement flow rate and simultaneously output stream to.This has brought difficulty for the tidal bore flow rate and direction measurement in many big tidal bores river.Also have some flow rate and direction meters,, can't satisfy the tidal bore river the anticorrosive requirement of equipment though dynamic range is big, measuring accuracy is high.Meanwhile, the contact type measurement mode is also very high to the requirement of the installation of equipment, particularly big tidal bore river, and the impulsive force of its morning and evening tides makes many common flow rate and direction measuring methods to implement therein.
Summary of the invention
Order of the present utility model is at the deficiencies in the prior art, and a kind of non-contact measurement apparatus of tide current flow speed and direction is provided.
The utility model comprises the radar wave current meter, and the radar wave current meter is fixed on the The Cloud Terrace of band tripod, and the pin of The Cloud Terrace is arranged at the bottom of the bridge on the extension.
The Cloud Terrace is provided with and the The Cloud Terrace table top can be carried out the adjusting lever that direction is up and down adjusted, make electric wave current meter and water (flow) direction over against, and spend less than 45 with the angle of river surface A.
At the bottom of the bridge at the bottom of extension and the bridge for being rigidly connected.
The output interface of radar wave current meter is directly inputted in the signal box that is placed on the outstanding position of bridge pier.
The top of signal box is provided with tidal lights, the bottom is provided with long-range output interface.
Adopt the utility model wide range, non-contacting radar wave current meter measuring method have realized the flow rate and direction measurement of the morning and evening tides of spring tide between flood season.The utility model is simple in structure, the installation and maintenance expense is low.

Embodiment
As shown in Figure 1, a kind of contactless tide current speed measuring device comprises radar wave current meter 1, and radar wave current meter 1 is fixed on the The Cloud Terrace 2 of band tripod, and the pin of The Cloud Terrace 2 is arranged at the bottom of the bridge on the extension 3.The bridge base should be higher than river surface more than 8 meters, and the distance of radar wave current meter Lijiang River surface current speed measurement point is no more than 100 meters.
The Cloud Terrace 2 is provided with and the The Cloud Terrace table top can be carried out the adjusting lever 4 that direction is up and down adjusted, make electric wave current meter 1 and water (flow) direction over against, and with the angle of river surface A less than 45 degree.
Extension 3 and B at the bottom of the bridge are for being rigidly connected at the bottom of the bridge.
The output interface 5 of radar wave current meter is the RS232 standard signal, is directly inputted in the signal box 6 that is placed on the outstanding position C of bridge pier.
Tidal lights 7 are equipped with at the top of signal box 6, and when detecting morning and evening tides, tidal lights are bright.
The bottom of signal box 6 is provided with long-range output interface 8, and conversion of signals can be carried out remote transmission after becoming fieldbus signals such as RS485 or Lonworks.
During measurement, the radar wave current meter is connected the output signal of receiving sensor with signal box.The interface of current meter adopts RS232 usually, can directly read the flow velocity and the flow direction by the RS232 agreement.Owing to adopted non-cpntact measurement, can avoid the impact and the corrosion of tidewater.The direction of measurement of noting sensor should be less than 45 degree angles with water (flow) direction.
