Abstract
The utility model provides a hose type optical fiber displacement transducer which comprises an enclosed pipe fitting, an internal magnetic component, an external magnetic component, a floater, an optical code disc, an upper guide wheel, a lower guide wheel and a slide wire. The hose type optical fiber displacement transducer is characterized in that the enclosed pipe fitting adopts flexible hoses which have enough strength, such as a metal corrugated pipe, a spiral pipe, a rubber pipe, a nylon pipe, etc. The upper guide wheel is a gear type guide wheel, and the slide wire is a metal soft wire or a rack sliding wire or a chain slide wire or a metal hole strip type slide wire which is matched with the slide track of the upper guide wheel and the lower guide wheel. The outer cover of the pipe end of the enclosed pipe fitting is provided with a gear which is meshed with the gear type upper guide wheel each other. The horizontal shaft of the gear is connected with a rotary shaft of a mechanical counter by a set of bevel gears. The signals of the optical code disc are sent to a secondary instrument by the optical fiber. The hose type displacement transducer is especially suitable for checking the liquid level of a very large and very deep container. The liquid level values can be read directly by the mechanical counter under the situation that the power is cut off, and can be checked with the reading values of the secondary instrument.
Description
Technical field:
The utility model belongs to the displacement measurement technical field, particularly a kind of hose type optical fibre displacement sensor.
Background technology
Displacement transducer all is widely used in fields such as chemical industry, metallurgy, papermaking.Existing displacement transducer has mechanical type, electromagnetic type is arranged, and photoelectric type is also arranged.The range of application that these sensors have is narrower, the complex structure that has, and the measuring accuracy that has is not high, and result of use is bad.Utility model patent ZL9922358.6 provides a kind of displacement transducer, formed by a displacement sensing assembly and a rotary encoder, the displacement sensing assembly comprises a closed stationary pipes, the a pair of guide wheel that is arranged on the stationary pipes upper and lower end, be centered around the slip between lower tumbler, be fixed on the interior magnetic cell on the sideslip line, the outer magnetic cell that can slide up and down that is enclosed within on the stationary pipes outer wall is formed, rotary encoder is fixed on the guide wheel shaft, can adopt incremental or absolute type optical code disk or code disc.This displacement transducer is used as displacement transducer and obtains good effect.When existing various displacement transducers being used for detecting the liquid level that is contained in the very big very dark container, the length of stationary pipes just must be very long, and what have reaches several meters, and tens meters, even tens meters.In this case, make stationary pipes, bring inconvenience will for transportation, installation etc. with inflexible hard tube.In addition,, must just can draw liquid level signal, can't directly read liquid level signal with mechanical system through after the data processing because output is light or electric signal.
Summary of the invention
The purpose of this utility model provides a kind of optical fiber liquid level survey sensor of hose type, when needs are made very long displacement transducer, it can be bent to circle or U-shaped, recovers its original form during installation again.
Another purpose of the present utility model provides a displacement transducer that has mechanical counter, can directly read liquid level data from counter.
According to hose type optical fibre displacement sensor of the present utility model, comprise outer tube, lower tumbler and lower guide wheel shaft thereof, upper block and upper block axle, slip, be fixed on the interior magnetic cell on the sideslip line, be contained in the outer magnetic cell that can on the outer wall of outer tube, slide up and down in the float, be contained in the digital disk on the upper block axle, the pipe end outer cover, described outer tube is the flexible flexible pipe with sufficient intensity, and described upper block is the gear type guide wheel, described slip is and upper and lower guide wheel slideway matches metal flexible cord or tooth bar, chain or metal aperture banding pattern slip.
A gear that is meshed with the gear type upper block is set in the described pipe end outer cover, and this gear transverse axis is connected by the turning axle of one group of conical gear and mechanical counter.
The transverse axis of this gear is connected by the turning axle of one group of conical gear and mechanical counter.
According to the utility model, described tool can adopt metallic bellows, metal thin-wall spiral pipe, rubber tube, nylon tube or plastic tube with the flexible flexible pipe of sufficient intensity.
The slideway of magnetic cell in can also in this has the flexible flexible pipe of sufficient intensity, being provided with.
According to hose type optical fibre displacement sensor of the present utility model, except characteristics that can be crooked, because the gear type sliding wheel and the rack type slip that adopt, not only prevented the relative slippage between guide wheel and the slip, and can drive mechanical counter by conical gear, can't work and influence a difficult problem that reads liquid level signal thereby solved under power-off condition electro-optical system.
