Abstract
The utility model relates to a liquid level gauge for flexible tank, consisting of a telescopic guy rope mechanism, a transmission mechanism, an angle sensor, a heavy hammer and a shell body, wherein, the lower end of a guy rope of the telescopic rope hauling mechanism is connected with the heavy hammer, and the telescopic guy rope mechanism is connected with the angle sensor through the transmission mechanism, and the telescopic guy rope mechanism, the transmission mechanism and the angle sensor are jointly arranged in the shell body. A measuring instrument is arranged on the top of a flexible tank, the guy rope and the heavy hammer are extended into the flexible tank, and the heavy hammer is suspended to the bottom of the tank. When liquid level in the tank changes, a height between the top of the tank and the bottom of the tank changes, and so does the guy rope. The angle sensor collects such displacement change, measures a displacement electric signal of tank height, and then calculates a capacity volume of the medium in the flexible tank. The utility model has the advantages of simple structure, high measurement precision, low cost, convenient installation without changing main body structure of the flexible tank, and can be used for liquid level height measurement of oil, water, chemical raw materials and other liquid medium stored in the flexible tank.
Description
Technical field
The utility model relates to a kind of level gauging technology, particularly a kind of instrument that the liquid level of soft pot is measured.
Background technology
Soft pot is a kind of soft, Foldable vessel, aspect the liquid mediums such as oil storage, water, industrial chemicals the usefulness of reflecting is being arranged all.Because its unique flexibility, it is carried out the mode that level gauging can not adopt conventional hardware jar, at present indirect metering system is mainly adopted in the measurement of soft pot liquid level, as mainly being to adopt the mode that installs type double flow meter on the pipeline that is connected pumped (conveying) medium with soft pot additional, the medium cumulative amount that promptly detects the turnover jar converses the level value and the capacity of jar interior medium, and this mode exists flowmeter that complicated, shortcomings such as measuring accuracy is low, cost height are installed.Now also there are not direct measuring method and special-purpose measuring instrument.
Summary of the invention
The purpose of this utility model is the deficiency at the prior art existence, propose a kind of simple in structure, measuring accuracy is high, cost is low, easy-to-install soft pot fluid level measuring instrument, need not to change the agent structure of soft pot, satisfy the requirement that soft pot is used for explosion-proof place simultaneously.
The technical solution of the utility model is as follows:
The soft pot fluid level measuring instrument mainly is the characteristic according to soft pot, reflects the height value that is stored in soft pot medium liquid level by the height change of measuring between soft pot tank body top and the tank base.This measuring instrument is made of extension type pull rope mechanism, gear train, angular transducer, weight and housing.The stay cord lower end of extension type pull rope mechanism connects weight, and is connected with angular transducer by gear train, and extension type pull rope mechanism, gear train, angular transducer are contained in the housing jointly.
Described angular transducer can be selected present existing multiple sensors, as rotary-type current potential device, rotary coder or rotary-type photoelectric commutator etc.
Described gear train adopts magnetic transmission mechanism or other mechanical type gear trains.Magnetic transmission mechanism can be a contact, for the soft pot of flammable and combustible liquids such as oil in storage, adopts contactless magnetic transmission mechanism, be convenient to like this angular transducer and the liquid of surveying are effectively isolated,
Described housing is separated into two chambers, telescopic pull rope mechanism and angular transducer be loaded on respectively these two indoor, to reach, meet requirement of explosion proof with mechanical transmission mechanism and electric signal transducer purpose independently.
In addition, for the soft pot of flammable and combustible liquids such as oil in storage, the housing of measuring instrument adopts explosion-proof casing.
During use measuring instrument is installed in the soft pot top, the stay cord and the weight of extension type pull rope mechanism are put in the soft pot, stay cord is terminal to be connected weight and it was hung down to a jar end, variation along with liquid level in the soft pot, height between tank body top and the tank base changes, and the length that drives stay cord changes, and measures the displacement electric signal of tank body height by angular transducer, because the characteristic of soft pot, the displacement signal of tank body height can reflect the variation of soft pot medium liquid level.The electric signal of secondary instrument by special use and the output of computer processing system acquisition angles sensor can calculate the capability value of soft pot medium.
Compared with prior art, the utlity model has following advantage: measuring instrument is simple in structure, and simple installation can be directly used in the level gauging of soft pot; The mode that employing is isolated the sensor and the medium of surveying fully is not subjected to the restriction of the dielectric behavior of surveying, the measuring accuracy height; The agent structure cost that need not to change soft pot is low; Substantially be not subjected to the restriction of environmental baseline, satisfy the requirement that soft pot is used for explosion-proof place simultaneously.The utility model can be used for the liquid level of liquid mediums such as oil storage, water, industrial chemicals and measures.
Description of drawings
Fig. 1 is the structural representation of this measuring instrument;
Fig. 2 is the scheme of installation of this measuring instrument on collapsible fuel tank.
Embodiment
Below be that example is elaborated to the utility model with the level gauging of collapsible fuel tank.
Referring to Fig. 1, this is a kind of structure realization of soft pot fluid level measuring instrument, is made of extension type pull rope mechanism, gear train, angular transducer, weight 18 and housing 11.Housing 11 is an explosion-proof casing, is separated into two chambers, extension type pull rope mechanism and angular transducer be spaced be loaded on these two indoor, the chamber part at extension type pull rope mechanism place has and the tank connected joint 19 of software.The extension type pull rope mechanism is made of reel assembly 16 and stainless steel stay cord 17, and weight 18 is connected stainless steel stay cord 17 lower ends, and the weight of weight 18 will make it hang down to collapsible fuel tank 3 bottoms (seeing shown in Figure 2).What gear train adopted is a pair of magnet steel 14 and 15, is installed in reel assembly 16 axle heads of extension type pull rope mechanism and wheel set assembly 13 axle heads of angular transducer relatively, with the noncontact form rotation of extension type pull rope mechanism is passed to angular transducer.What angular transducer adopted is rotary-type current potential device, is made up of wheel set assembly 13 and potentiometer assembly 12, and magnet steel 14 drives wheel set assemblies 13 rotations, and wheel set assembly 13 drives potentiometer assembly 12 again, and potentiometer assembly 12 passes signal by pin.
