Abstract
This utility model be related to it is a kind of be horizontally mounted for what tunnel-side level gauge was installed, the protective cover is divided into left and right two sections, and every section of protective cover includes cover plate（1）With horizontal U-shaped side plate (2), the side plate（2）On have wire hole（4）, wire hole（4）Top is wing plate（3）, protective cover wing plate（3）Upper perforate is mechanically connected with fixed hole position on clamp of sensor；The opening of the U-shaped side plate (2) of left and right two sections of protective covers is oppositely arranged.A kind of underwater performance strain gauge protective cover of the present utility model can avoid sensor from causing data unstable or destruction because of modes such as current scour or mechanical impacts; sensor protective cover can be just arranged on clamp of sensor in the sensor production stage in addition, the installation exercise time of reduction underwater sensor.
Description
Technical field
This utility model is related to a kind of underwater performance strain gauge protective cover, is mainly used in optical fiber optical grating stress sensing
The sensor of the two ends such as device, displacement transducer clamping is encapsulated in inside protective cover.
Background technology
Fiber-optic grating sensor has been commonly used for the structure monitorings such as bridge tunnel.Due to fiber grating moisture resistance itself
Can be good, therefore it is applied to underwater monitoring.But install sensor can be affected by flowing water impulsive force in flowing water, cause sensing
Device test data misalignment, or receiving mechanical impacts causes sensor to be destroyed.Sensor protective cover before is both needed to enter structure
Row drilling is installed, and sensor protective cover as in the previous is not directly installed on clamp of sensor by the way of drilling is installed, then
The test effect of sensor can be eventually affected because of the stressing influence of protective cover itself, and the set-up time is longer.
Utility model content
The purpose of this utility model is to provide a kind of underwater performance strain gauge protective cover, can avoid sensor because of current
Wash away or the mode such as mechanical impacts cause data unstable or destruction, in addition sensor protective cover can the sensor production stage just
On clamp of sensor, the installation exercise time of underwater sensor is reduced.
The technical scheme in the invention for solving the above technical problem is：A kind of underwater performance strain gauge protection
Cover, the protective cover are divided into left and right two sections, and every section of protective cover includes cover plate and horizontal U-shaped side plate, on the side plate
There is wire hole, be wing plate above wire hole, perforate on protective cover wing plate is mechanically connected with fixed hole position on clamp of sensor；
The opening of the U-shaped side plate of left and right two sections of protective covers is oppositely arranged.
Further, described underwater performance strain gauge protective cover, wire hole are ear formula square hole.
The protective cover adopts stainless steel.
Compared with prior art, the utility model has the advantage of：
Protective cover adopts separation design, both sides to be separately mounted on the fixture of two sections of sensor, due between protective cover
It is not rigidly connected, therefore the stress of sensor and displacement effect will not be impacted.
Protective cover side has ear formula square hole to design, and clamp of sensor is drawn from square hole, therefore can be in sensing
Device production period is just installed the installation time under water for reducing sensor on a sensor by protective cover, and raising is installed under water
Construction working efficiency.
Sensor protective cover adopts high-quality stainless steel, is affected to lead by corrosion oxidation when can avoid operation under water
Protective cover corrosion is caused, is damaged or is come off.
Description of the drawings
Fig. 1 is a kind of integral assembling figure of underwater performance strain gauge protective cover of this utility model.
Side plate construction diagrams of the Fig. 2 for this utility model underwater performance strain gauge protective cover.
Wherein：
1. protective cover cover plate；2. protective cover side plate；3. protective cover wing version；4. wire hole.
Specific embodiment
This utility model is described in further detail below in conjunction with accompanying drawing embodiment.
As shown in figure 1, a kind of underwater performance strain gauge protective cover in the present embodiment, the protective cover is divided into left and right
Two sections, per section includes cover plate 1 and side plate 2, has wire hole 4 on side plate 2, is wing plate 5 above wire hole 4, protective cover wing plate 5
Upper perforate is mechanically connected with fixed hole position on clamp of sensor.
Wire hole 4 is ear formula square hole.
The side plate is made up of a horizontal U-shape structure, the U-shaped opening end of the side plate of the two sections of protective covers in left and right three blocks of sheet materials
First to arranging.
The protective cover adopts 304 stainless steel of high-quality
In addition to the implementation, this utility model also includes other embodiment, all employing equivalents or equivalent
The technical scheme that substitute mode is formed, all should fall within this utility model scope of the claims.
