Description
Technical field
The invention belongs to electricity chromatography image-forming data acquisition and fields of measurement and structure fields.
Background technology
In recent years, the method for electricity tomography is used in various aspects, but due to many testee surfaces
It is unsmooth so that partial electrode piece can not achieve full contact, and the mutual spacing that distributing electrode is placed every time also is difficult to do
To consistent, therefore the difference of placement location also results in imaging and is likely to occur more serious distortion every time, electrode when measurement data
Placement problem be the key that tomographic data acquisition technique.
Invention content
The object of the present invention is to provide a kind of arc-spark stands making electrode and surface realization Full connected.Technical solution is as follows：
A kind of deflation formula folding electrode frame for electricity tomography, including protection band, expansion bracket and multiple electrodes piece
Part, wherein protection band has elasticated, is covered in the periphery of expansion bracket；Expansion bracket includes the elasticity branch of multiple embowments
Strut, the end of adjacent spring supporting rod are fixed on the back side of the same electrode slice, the maximum deflection part support of elastic supporting bar
On the inner wall of protection band.
When the object to various sizes measures, expansion bracket can stretch different degree to fit according to different sizes
Various testee edges are answered, while electrode slice is tightly pressed against testee surface by the structure for tightening formula, makes electrode and surface
It realizes Full connected, and can easily adjust the distance between each electrode slice, greatly subtract at data source to realize
Small Acquisition Error.The present invention can adapt to various measuring environments, the maximum raising precision on hardware configuration, reduce Acquisition Circuit
With the calibration complexity of programmed algorithm.If the arc-spark stand as wearable measuring device, filled compared to large-scale wearable measurement
It sets and Mechanical measurement equipment, the design is small, and light-weight and wearing is simple.
Description of the drawings
Fig. 1 is the schematic diagram of electricity chromatography imaging measurement system arc-spark stand in the ideal situation.In Fig. 1：
1 protection band；2 expansion brackets；3 electrode slices；4 testee edges；5 elastic supporting bars.
Its internal testee can change according to the practical difference for measuring object, and elastic deflation frame 2 is suitable for
Each type objects of different shapes.
Specific implementation mode
The present invention is based on electricity to chromatograph imaging measurement system, is uniformly distributed measuring electrode simultaneously with a kind of telescopic structure
It is close to testee surface, and the structure of elasticity can arbitrarily adjust the position of each electrode according to actual demand, meets and survey
Amount needs.As shown in Figure 1, the design includes mainly three parts：
Protection band 1：Protection band does not have the effect in structure, since expansion bracket 2 has elasticity, external sharp parts
Have certain acutance, external structure is wrapped up with the protection band 1 with elasticated, is played a protective role.
Expansion bracket 2：Stretching structure is the core of design, all fixed two connected expansion brackets 2 above each plate electrode,
It, which makes, selects specific flexible material, and pressure is generated to two lateral electrodes 3 after each stretch.
Electrode slice 3：Electrode is a part for imaging system gathered data, and electrode 3 is exactly fixed on by the purpose of the design
On holder, keep its position controllable, is close to testee edge 4.
Electricity tomography has very wide application range, can not only be imaged to human organs such as thoracic cavities, also may be used
To be applied to the devices such as pumping conduit, therefore there is different design schemes in different application environments, is described as follows：
This structure has material very high requirement, material must have elasticity, to meet the flexible purpose pressed；And want root
Corresponding shelf size is determined according to the magnitude range at testee edge 4.
Since tomography is useful in various environment, this structure should also be selected according to the difference of actual operating condition
Suitable making material and fixed structure.If applied in large-scale pipeline imaging system, the rigid material that intensity is larger is needed
Screw or welding manner can be used under the premise of carrying out insulation in the interface of material, electrode slice 3 and expansion bracket 2.To large-diameter pipe
When road is imaged, the steel plate of thinner thickness can be used in expansion bracket 2, it is ensured that the elasticity of expansion bracket, structural stability and resistance to
With property, screw or welding manner can be used in electrode slice 3 and the connection of expansion bracket 2, and insulation is fixed between electrode and steel plate
Gasket or in electrode backside coating insulating layer.When being imaged to torso model, the elastic insulator material of expansion bracket 2 can
Using the lightweights material such as ABS plastic, both can guarantee that the elasticity of material, lighter weight were also beneficial to operate, electrode slice 3 with stretch
The connection of contracting frame 2 can use the modes such as hot melt.
Since the outside of structure is more sharp, in order to protect operating personnel and tested personnel, one is added in the outside of structure
Layer protection band 1, this protection band will also have elasticity, and the soft material such as elastic cloth band can be used.
3D printing technique or foundry engieering may be used according to actual demand to make, expansion bracket 2 can be opened up completely
It opens, surround testee when in use one week and generates the power inwardly pressed.When measurement, package unit is directly sleeved on measured object
Outside body, since expansion bracket 2 has elastic telescopic performance, it can tightly be attached to testee edge 4, elastic nature
The position between each electrode slice 3 can be adjusted, the status requirement to electrode spacing when measuring is met.
