Abstract
The utility model belongs to the technical field of optical sensing engineering application, and relates to a fixture for fixing a strain sensing cable, which is characterized in that: an upper groove and a lower groove with arc curved surfaces are respectively arranged on the corresponding positions of a base and a cover plate, and are fastened with each other to form an elliptic cable clamping groove. The utility model has the beneficial effects that: the elliptic cable clamping groove clamps and fixes the strain sensing cable, the arc curved surface of the cable clamping groove is fit with the surface of the strain sensing cable, when the fixture is used for fixing, the cable is uniformly stressed, part of the fixing part of the cable does not deform, and no added losses is caused; and moreover, the base and the cover plate are separately fixed, so the construction and installation carried out in the engineering field are convenient, and the prestress of the cable can be reasonably distributed.
Description
Technical field
The utility model belongs to light sensing engineering applied technical field, relates to a kind of anchor clamps that are used for fixing straining sensing optical cable.
Background technique
That the distributing optical fiber sensing technology has is highly sensitive, be easy to lay, to detected object do not have destruction and interference, anti-electromagnetic interference capability strong, can carry out distribution measuring and heat transfer agent is easy to by characteristics such as Optical Fiber Transmission and networkings, development in recent years is swift and violent.The off-line that will extensively adopt at present based on the distributive fiber optic strain sensed system of Brillouin scattering, static state, passive damage check, change online, dynamic, real-time monitoring and control into, can realize monitoring structural health conditions tunnel, dykes and dams, heavy construction etc.Because the existing sensing function of optical fiber has signal transfer functions again in the distributive fiber optic strain sensed system, engineering practicability difficulty is bigger.At present, the engineering that the distributive fiber optic strain sensed system carries out monitoring structural health conditions is applied in domestic at the early-stage, and relevant engineering practical technique rarely has report.
For distributive fiber optic strain sensed system engineering, during the laying of straining sensing optical cable, need usually to fix with anchor clamps, the clamp groove in the present conventional anchor clamps mostly is flat bottomed recess, and the anchor clamps folder is too loose, may cause producing relative displacement between optical cable and the anchor clamps; Anchor clamps hold tension, may cause optical cable local deformation again, introduce added losses; And flat bottomed recess clamp groove and optical cable side face can't coincide and fit tightly consistently, and fixedly degree of tightness is appropriate to be difficult to accomplish optical cable in the work progress, and then have influence on the effective monitoring distance and the sensing sensitivity of whole strain sensing system.
The model utility content
For overcoming above-mentioned shortcoming, the purpose of this utility model is: a kind of anchor clamps that are used for fixing straining sensing optical cable are provided, and it is the arc-shaped curved surface groove that the clamp groove levels off end groove, is convenient to optical cable laying installation at the construction field (site), and optical cable prestressing force can rationally be set.
For achieving the above object, the technological scheme that adopts is: a kind of anchor clamps that are used for fixing straining sensing optical cable, comprise base, cover plate and place clamp groove between described base and the cover plate, it is characterized in that: be equipped with the upper and lower groove of curved curved surface on the relevant position of described base and described cover plate respectively, and upper and lower groove fastens composition ellipticity clamp groove mutually.
Be equipped with base on the described base and install and fix the hole; The relevant position is equipped with through hole on the described cover plate.
The beneficial effects of the utility model are: the ellipticity clamp groove that described base and described cover plate fasten composition mutually grips straining sensing optical cable, clamp groove arc-shaped curved surface coincide consistent with the straining sensing optical cable surface, straining sensing optical cable is evenly stressed fixedly the time, fixed position local invariant shape, does not introduce added losses; And base and cover plate separate fixingly, and the engineering site construction install convenience can rationally be provided with optical cable prestressing force.
Description of drawings
The utility model is described in further detail below in conjunction with description of drawings and embodiment.
Fig. 1 is the utility model structural representation;
Fig. 2 is the A-A cross-sectional view of Fig. 1;
Fig. 3 is the B-B cross-sectional view of Fig. 1.
Among the figure, the 1-base; The 2-base installs and fixes the hole; The 3-low groove; The 4-cover plate; 5,5 '-cover plate whorl of base is connected and fixed the hole; The 6-upper groove; 7-cover plate through hole.
Embodiment
From Fig. 1 the utility model structural representation, and the cross-sectional view shown in Fig. 2 and Fig. 3 as seen, a kind of anchor clamps that are used for fixing straining sensing optical cable described in the utility model, comprise base 1, cover plate 4 and place clamp groove between described base 1 and the cover plate 4, it is characterized in that: described base 1 is equipped with the low groove 3 of curved curved surface, be equipped with the upper groove 6 of curved curved surface on the relevant position of described cover plate 4, and described upper groove 6 and the low groove 3 mutual composition ellipticity clamp grooves that fasten.
Be equipped with base on the described base 1 and install and fix hole 2; The relevant position is equipped with through hole 7 on the described cover plate 4.
During use, for ease of processing, clamp base 1 and cover plate 4 all adopt copper to do, and utilize setscrew to pass and install and fix hole 2 on the base 1, earlier base 1 are mounted on body surface to be monitored.Extraordinary strain optical cable laying is positioned in the low groove 3 on the described base 1, and the cover plate 4 and align with base 1 of closing utilizes screw to pass the cover plate whorl of base and is connected and fixed hole 5 and 5 ', realizes cover plate 4 is fixedlyed connected with the screw thread of base 1, uses easily.Through hole 7 is given setscrew cap vacating space on the cover plate 4, makes cover plate 4 and base 1 can fit closely.Because upper groove 6 and low groove 3 curved curved surfaces, and fasten composition ellipticity clamp groove mutually.The particular design of arc-shaped curved surface, make clamp groove arc-shaped curved surface coincide consistent with the straining sensing optical cable surface, optical cable is evenly stressed fixedly the time, fixed position local invariant shape, does not introduce added losses, thereby guarantees that effectively effective monitoring distance of strain sensing system and sensing sensitivity are unaffected.
