Abstract
The utility model relates to a double-rod tide flow velocity measuring device, aiming to solve the problem of narrow measurement dynamic range of a conventional flow velocity and direction metering device. The measuring device provided by the utility model comprises two fixing rods with the upper parts above the water surface and the bottom parts fixed on a concrete block buried in the sand in the river; sliding rings are sleeved on the two fixing rods respectively; a floating platform and an equipment box are arranged between the two fixing rods and the equipment box is arranged on the floating platform; a float rod is vertically arranged in the center at the top of the equipment box; the side wall of the float rod and the top of the equipment box are connected through a fixed reinforcing rod; two connecting rods are arranged at the bottom of the equipment box; and a velocity meter is arranged below each connecting rod. The utility model adopts two velocity meters with wide measurement range and corrosion resistance, and the two velocity meters are arranged in two opposite directions, so as to realize tidal flow velocity measurement during spring-tide high water season.
Description
Technical field
The utility model belongs to the automatic control technology field, relates to a kind of pair of bar tide current speed measuring device.
Background technology
Present flow rate and direction meter not at the tidal current survey design, exists many problems.Dynamic range as 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 demanding demand of equipment though dynamic range is big, measuring accuracy is high.
Summary of the invention
The utility model purpose is exactly at the deficiencies in the prior art, and a kind of pair of bar tide current speed measuring device is provided.
The utility model comprises two fixed bars that vertically are provided with, and the top of fixed bar is positioned at more than the water surface, and the bottom of fixed bar is fixedly installed on the concrete block, and concrete block is embedded in the silt at the bottom of the river; Be with slip ring respectively on two fixed bars, slip ring can slide up and down along fixed bar.
Be provided with floating platform and equipment box between two fixed bars, equipment box is arranged on the floating platform; Floating lever vertically is arranged on the center at equipment box top, and the sidewall of floating lever is connected by fixing stiffener with the top of equipment box; A two pull bars end, other end fixedly connected with floating lever are respectively fixedlyed connected with two corresponding slip rings.
The bottom of equipment box is that the center symmetry vertically is provided with two connecting links with the floating lever, and every connecting link is arranged with velocimeter, and the direction of measurement of two velocimeters is opposite, and parallel with water (flow) direction.
The top of equipment box is provided with the sensor output interface, and the sensor output interface is connected with velocimeter.
The utility model adopt two on a large scale, corrosion-resistant velocimeter is by opposite both direction configuration, realized the fluid-velocity survey 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.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
