Abstract
The utility model is related to a kind of heat-insulated magnetic flux transducer, belongs to road and bridge engineering, and industry is monitored applied to structure safety and Health.It includes cover plate, outer protection tube, skeleton, asbestos board and aluminium foil thermal isolation film；It is fitted into after skeleton coiling in outer protection tube；The two ends of outer protection tube are sealed by cover plate respectively, and are integrally inserted in cable, and along the surface of outer protection tube and cover plate around one layer of asbestos board, one layer of band glue aluminium foil thermal isolation film is pasted in the outer layer of asbestos board.The utility model is solved because external high temperature is delivered to inside magnetic flux transducer, is internal temperature rise, and influence measurement force value obtains problem.Reflected by surface and isolate double thermal insulation, reduce magnetic flux transducer internal temperature by external influence, it is ensured that normal operation of sensor.And outside aluminium foil thermal insulation layer seals sensor outer surface, plays certain waterproof action.
Description
Technical field
The utility model is related to a kind of heat-insulated magnetic flux transducer, belongs to road and bridge engineering, strong safely applied to structure
Health monitors industry.
Background technology
Prior art：The physical principle that existing magnetic flux transducer is changed by cable stress magnetic conductivity, measure cable by
Power；Magnetic flux transducer shell is the strong stainless steel of thermal conductivity, and internal threads skeleton is the engineering plastics of easy processing；Due to
Magnetic flux transducer is affected by temperature larger, and the accuracy that sensor measures cable stress can be reduced when temperature change is larger.When
External temperature is higher, especially when summer, sun direct projection was stronger, and temperature is passed by the stainless steel jacket of magnetic flux transducer
Sensor internal is delivered to, is that internal temperature constantly increases, so as to directly affect the accuracy of measured data.
The content of the invention
The purpose of this utility model is to provide a kind of heat-insulated magnetic flux transducer, in existing magnetic flux transducer structure and
Technically, magnetic flux transducer surface heat transfer process is improved by increasing surface heat-barrier material, so as to reduce inside and outside sensor
The temperature difference.Especially when relatively strong, external temperature is higher for sun direct projection, heat can be prevented to enter sensor internal, temperature is reduced
Influence to measured value, to reach the purpose for improving measurement accuracy.
The utility model to achieve these goals, is adopted the following technical scheme that：A kind of heat-insulated magnetic flux transducer, it is wrapped
Include cover plate, outer protection tube, skeleton, asbestos board and aluminium foil thermal isolation film；
It is fitted into after skeleton coiling in outer protection tube；
The two ends of outer protection tube are sealed by cover plate respectively, and are integrally inserted in cable, along outer protection tube and the surface of cover plate
Around one layer of asbestos board, one layer of band glue aluminium foil thermal isolation film is pasted in the outer layer of asbestos board.
Outer protection tube is stainless-steel seamless pipe.
Asbestos board is the heat-insulating material for insulation.
Aluminium foil thermal isolation film not only has the advantages that moistureproof, airtight, shading, wear-resisting, nontoxic, and do not influence outside sensor
See.
When ambient temperature is too high, and sun direct projection is stronger, aluminium foil thermal isolation film can reflect away most of light and hot spoke first
Penetrate, then by the heat-insulated again of asbestos board, prevent external temperature from being delivered to inside, so that the temperature of sensor internal is maintained at
In certain limit, influence of the temperature to measurement force value is reduced, the accuracy and reliability of data is improved.
The beneficial effects of the utility model：
The utility model is solved because external high temperature is delivered to inside magnetic flux transducer, is internal temperature rise, influence
Measurement force value obtains problem.Reflected by surface and isolate double thermal insulation, reduce magnetic flux transducer internal temperature by extraneous shadow
Ring, it is ensured that normal operation of sensor.And outside aluminium foil thermal insulation layer seals sensor outer surface, plays certain waterproof action.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
The utility model is described in detail below in conjunction with the accompanying drawings：
A kind of heat-insulated magnetic flux transducer, it includes cover plate 1, outer protection tube 2, skeleton 3, asbestos board 4 and aluminium foil thermal isolation film 5;
It is fitted into after the coiling of skeleton 3 in outer protection tube 2；
The two ends of outer protection tube 2 are sealed by cover plate 1 respectively, and are integrally inserted in cable, along outer protection tube 2 and cover plate 1
One layer of band glue aluminium foil thermal isolation film 5 is pasted in the outer layer of asbestos board 4 in surface around one layer of asbestos board 4.
Outer protection tube 2 is stainless-steel seamless pipe.
Asbestos board 4 is the heat-insulating material for insulation.
Magnetic flux transducer is typically mounted on bridge cable, naked to be exposed on the external, can be by external environment influence.When extraneous temperature
Height is spent, when sun direct projection is stronger（Such as summer）, aluminium foil thermal isolation film 5 has reflected light and the function of heat radiation, then passes through tool
There is the asbestos board 4 of thermal-insulation function heat-insulated again, prevent external temperature from being delivered to inside, the temperature of sensor internal is maintained at one
Determine in scope, reduce influence of the temperature to sensor.
