Description
Technical field
The utility model relates to a kind of novel vibrating wire piezometer, relate in particular to the improvement of the sensing unit of string formula osmometer.
Background technology
The measurement of seepage water pressure is the important component part of safety monitoring, and its monitoring result directly influences the result that dam safety is analyzed, and therefore, needs the sensor of precision height, dependable performance to be used for long-term measurement.
At present, traditional vibrating wire piezometer mainly is made up of three parts: pressure imports parts, sensing unit and outgoing cable seal member.Wherein, sensing unit is the core component of osmometer, and interference fit is mainly adopted in the connection between each parts of sensing unit; Be threaded and auxiliary assemble with the mode of glue bond, therefore, each part need for bonding, be threaded and reserve certain space structure; Cause the sensing unit complex structure, size is bigger than normal, simultaneously; The resulting sensing unit of above-mentioned fit is not stable whole parts, receives external environmental interference easily, and the measured value reliability is lower; After on-the-spot long-term use of instrument, the performance of glue bond reduces greatly, is difficult to reach the better seal effect.Therefore, the major defect of traditional vibrating wire piezometer has: 1) osmometer one-piece construction size is bigger, can't adapt to the installation environment requirement of miniaturization; 2) it is relatively poor that vibrating wire piezometer is measured consistance, and measuring error is bigger; 3) sealing of traditional vibrating wire piezometer is relatively poor, receives external environmental interference easily, and long-time stability are relatively poor.
The utility model content
To the deficiency that exists on the prior art, the utility model provides a kind of novel vibrating wire piezometer, has changed the structure of traditional osmometer sensing unit; It is bigger than normal to have solved present vibrating wire piezometer physical dimension; Sealing property is unreliable, and long-time stability are general, defectives such as homogeneity of product difference.
To achieve these goals, the utility model is to realize through following technical scheme:
A kind of novel vibrating wire piezometer comprises:
Cable seal parts, containment vessel body component, sensing unit and pressure import parts, and said vibrating wire piezometer top is the cable seal parts, is used for fixing and the sealed electrical cable; Said cable seal parts bottom connects the containment vessel body component, and said sensing unit is positioned at the containment vessel body component, and said containment vessel body component bottom is provided with pressure and imports parts.
Above-mentioned sensing unit is formed and is comprised termination, top, intermediate host, base pressure reaction diaphragm; Termination, said top and intermediate host; Intermediate host and base pressure reaction diaphragm adopt the form of laser bonding to realize that the sensing unit sealing is welded as a whole after assembling.
The effect that the utility model is compared with prior art useful is:
(1), novel string formula osmometer one-piece construction is compact more; Further widened installation environment: novel string formula osmometer has changed the mode that original sensing unit each several part connects the glue bond of generally adopting at present; Need not on the each several part of sensing unit, to reserve the space structure that supplies bonding; Further reduced the size of sensing unit; Make the osmometer one-piece construction compact more, have present diameter generally to be reduced within the 21.5mm overall dimensions of osmometer, can adapt in the miniaturized environment such as a writing brush inside and install greater than 26mm.
(2), novel string formula osmometer stability is higher; Sealing is more reliable, and anti-external interference ability is stronger: the each several part of sensing unit after assembling, is adopted the high-precision laser welding; Form the sensing unit of more stable one, reduced because of artificially assembling having produced error.Because sensing unit inside has formed totally enclosed cavity; Sealing is more reliable on the one hand; Have the higher measuring value accuracy and the measurement capability of overrange, also greatly reduce the interference of external environment sensing unit, can adapt to more abominable external environment and measured value more reliable and more stable.
Description of drawings
Specify the utility model below in conjunction with accompanying drawing and embodiment;
Fig. 1 is the structural representation of this practicality;
Fig. 2 is the structural representation of sensing unit structure among Fig. 1.
Embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and be easy to understand understanding with effect, below in conjunction with embodiment, further set forth the utility model.
Like Fig. 1, as shown in Figure 2, a kind of novel vibrating wire piezometer comprises: cable seal parts 1, and containment vessel body component 2, sensing unit 3 and pressure import parts 4; Vibrating wire piezometer cable seal parts 1 are connected in containment vessel body component 2 tops, are used for fixing and the sealed electrical cable; Sensing unit 3 is positioned at containment vessel body component 2 inside, and containment vessel body component 2 bottoms are provided with pressure and import parts 4; Sensing unit 3 comprises termination, top 5, intermediate host 6, base pressure reaction diaphragm 7.
Between termination 5, osmometer top and the intermediate host 6, after having assembled, adopt the form of laser bonding to realize that the sensing unit integral sealing is welded as a whole between intermediate host 6 and the base pressure reaction diaphragm 7.
Novel string formula osmometer one-piece construction is compact more; Miniaturization: novel osmometer has adopted new cable seal parts, and has changed the connected mode that original sensing unit each several part part adopts glue bond, has further reduced the one-piece construction size of osmometer; With the integral outer diameter of present osmometer generally greater than 26mm; Be reduced within the 21.5mm, structure is compact more, and installation environment is further widened.
Novel string formula osmometer stability is higher; Sealing is more reliable, and anti-external interference ability is stronger: sensing unit each several part part after having assembled, is adopted the high-precision laser welding; Form one-piece construction more reliably, reduced because of artificially assembling having produced error.Because sensing unit inside has formed totally enclosed cavity; Sealing is more reliable on the one hand; Measurement capability with higher overrange; Simultaneously, also greatly reduce the interference of external environment to sensing unit, make sensor can adapt to more abominable external environment and measured value more reliable and more stable.
Novel string formula osmometer dependable performance, accuracy of measurement is higher: owing to adopted the pressure of stainless steel to import parts, help the infiltration of water pressure more, the measured value of sensing unit approaches real force value more.
More than show and described ultimate principle of the utility model and the advantage of principal character and the utility model.The technician of the industry should understand; The utility model is not restricted to the described embodiments; The principle of describing in the foregoing description and the instructions that the utility model just is described; Under the prerequisite that does not break away from the utility model spirit and scope, the utility model also has various changes and modifications, and these variations and improvement all fall in the utility model scope that requires protection.The utility model requires protection domain to be defined by appending claims and equivalent thereof.
