Abstract
A strain measuring apparatus used for ocean platform is disclosed that includes: first and second mounting bases, seal cavity, and strain bridge. The first and second mounting bases are mounted symmetrically on the both sides of seal cavity; the seal cavity is mounted on the measuring location of ocean platform, said strain bridge is mounted in seal cavity, the two ends connect with first and second mounting bases, strain gages are mounted on the strain bridge. The measurement results are got by strain gages via the measuring location of ocean platform and the variation of location measured by the strain bridge. So it can improve the measurement tolerance greatly, be used in deep ocean to prevent the strain gages form corrosion.
Description
Technical field
The present invention relates to a kind of strain gauge means that is used for ocean platform.
Background technology
Ocean platform is one of important foundation facility of submarine oil detection, exploitation etc.Ocean platform is owing to be to build on the seabed, so it is subjected to the impact of seawater and ice load for a long time.In order to detect the tension and compression mechanics influence that is subjected on its foundation structure, normally stick foil gauge in relatively more responsive place, directly measure the strain at this position.Though this way is simple, is subjected to detecting the influence of position bulk deformation, its strain measurement data on certain specific direction have very big error, thereby cause that seawater and ice load are had very big deviation to the interpretation of result of the influence of ocean platform.In addition, also can make measuring error bigger to the measurement that is deep into seawater part owing to corrosion and other influence that foil gauge is subjected to seawater.
Summary of the invention
At the problem of above-mentioned existence, the object of the present invention is to provide a kind of strain gauge means that is used for ocean platform, this device not only can improve the sensitivity of measurement greatly, but also can measure under water.
For achieving the above object, a kind of strain gauge means that is used for ocean platform of the present invention comprises: first and second mount pad, seal chamber and strain bridge, first and second mount pad symmetry is fixed on the both sides of seal chamber, the sealing cavity can be fixed on the measured position of ocean platform by first and second mount pad, described strain bridge is arranged in the seal chamber, its two ends fix with described first and second mount pad respectively, are fixed with foil gauge on this strain bridge.
Further, described strain bridge has suitable width and thickness, and is made by toughness material.
Further, described strain bridge is linear or S shape or stepped appearance.
The present invention is by directly being fixed on the measured position of ocean platform, by the variation of strain bridge response measurement position, and then obtain measurement result, therefore can improve the error of measurement greatly by foil gauge, and can be used for the deep-sea, prevent the corrosion of seawater to foil gauge.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Fig. 2 is that strain bridge is the structural representation of S shape.
Fig. 3 is that strain bridge of the present invention is step-like structural representation.
Embodiment
As shown in Figure 1, the present invention includes: first and second mount pad 4,5, seal chamber 1 and strain bridge 3, first and second mount pad 4,5 symmetries are fixed on the both sides of seal chamber 1, seal chamber 1 can be fixed on the measured position of ocean platform by first and second mount pad 4,5, strain bridge 3 is arranged in the seal chamber 1, its two ends fix with first and second mount pad 4,5 respectively, are fixed with foil gauge 2 on this strain bridge 3; Wherein, strain bridge 3 has suitable width and thickness, and make by toughness material, mainly be when changing in order to be subjected to tension and compression in measured position, make this variation can obtain reflection more realistically along the length direction of strain bridge 3, thereby the strain variation strain bridge 3 of measuring this position exactly can be to make with seal chamber 1 one, also can be to be fixed in the seal chamber 1 by modes such as welding.Among Fig. 1, strain bridge 3 is a linear, also can adopt as shown in Figure 2 S shape or stepped appearance shown in Figure 3, specifically as a result shown in the table 1 of test:
The relation of load that table 1 adds and strain
