Abstract
The utility model discloses a kind of stationary installation of circumference intrusion detection vibration optical fiber, belong to the erecting tools field of vibration optical fiber in perimeter protection technology, comprise the anchor ear portion of cuff enclosure wall railing and connected fixed head; Fixed head is vertically arranged, and the plate face of fixed head is provided with the groove holding vibration optical fiber.The face that is fixed as of vibration optical fiber is contacted, and stabilized structure is firm, quick for installation, simple and convenient.
Description
Technical field
The utility model relates to the erecting tools field of vibration optical fiber in perimeter protection technology along the line, in particular to a kind of stationary installation of circumference intrusion detection vibration optical fiber.
Background technology
Vibration optical fiber perimeter protection facility is being subject in extraneous vibration situation based on specialty optical fiber, the light signal causing inside of optical fibre to transmit changes, be arranged on the change of on-the-spot defence area Module recognition light signal and identification invades behavior, carry out interlink warning, widespread use on railway perimeter protection.Current vibration optical fiber mostly adopts and is tied on enclosure wall top or metal mesh sheet fence by vibration optical fiber sticking type, and bearing is generally point cantact and fixes, and fixing steadiness is poor.
Utility model content
The purpose of this utility model is the stationary installation providing a kind of circumference intrusion detection vibration optical fiber, to solve the problem of the existing steadiness difference directly the ground colligation of vibration optical fiber sticking type brought on enclosure wall or fence.
For realizing the utility model object, the technical scheme of employing is: a kind of stationary installation of circumference intrusion detection vibration optical fiber, comprises the anchor ear portion of cuff enclosure wall railing and connected fixed head; Fixed head is vertically arranged, and the plate face of fixed head is provided with the groove holding vibration optical fiber.
Further, described anchor ear portion is U-shaped anchor ear, and fixed head is fixedly connected on the openend of U-shaped anchor ear.
Further, the notch of described groove is towards side, anchor ear portion.
The beneficial effects of the utility model are, enclosure wall keeps at a certain distance away this jig is installed, by anchor ear portion cuff on enclosure wall railing, vibration optical fiber is put into the groove on fixed head plate face, the installation realizing vibration optical fiber is fixed, this bearing is groove inside surface, the face that is fixed as of vibration optical fiber is contacted, stabilized structure is firm, install with sticking type or directly adopt compared with jig is fixedly mounted on enclosure wall by bolt, improve the fastness that vibration optical fiber is installed, and the notch of groove towards side, anchor ear portion time, namely towards the enclosure wall rail surface of anchor ear portion cuff, the surface of such enclosure wall railing and groove inside surface serve the spacing fixation to vibration optical fiber jointly, install also more quick, do not need by other extra retaining elements, vibration optical fiber is loaded in groove and can realize fixing, simple and convenient, installation jig of the present utility model is not limited in railway perimeter protection, it can be widely used in the installation of the vibration optical fiber that the place enclosure walls such as community are monitored.
Accompanying drawing explanation
Fig. 1 is the front view of the stationary installation of the circumference intrusion detection vibration optical fiber that the utility model provides;
Fig. 2 is the vertical view of stationary installation shown in Fig. 1;
Fig. 3 is the using state schematic diagram that stationary installation shown in Fig. 1 is mounted to enclosure wall railing.
Embodiment
Also by reference to the accompanying drawings the utility model is described in further detail below by specific embodiment.
Fig. 1, Fig. 2 show the stationary installation of the circumference intrusion detection vibration optical fiber that the utility model provides, and comprise anchor ear portion 1 and the connected fixed head 2 of cuff enclosure wall railing; Fixed head 2 is vertically arranged, and the plate face of fixed head 2 is provided with the groove 3 holding vibration optical fiber.
Anchor ear portion 1 can be U-shaped anchor ear, simple and practical, and fixed head 2 is fixedly connected on the openend of U-shaped anchor ear, and namely fixed head is while being fixed on enclosure wall railing by U-shaped anchor ear, also installs fixing vibration optical fiber by the groove 3 on its plate face.Fixed head 2 can be sheet metal component, and groove 3 can be bent to form by the side of sheet metal component, and the making of such integral type is more simple and convenient.
The notch of groove 3 is towards side, anchor ear portion 1, and the surface of enclosure wall railing and groove can be utilized jointly to fix vibration optical fiber, and using state as shown in Figure 3 simultaneously.
The foregoing is only preferred embodiment of the present utility model, be not limited to the utility model, for a person skilled in the art, the utility model can have various modifications and variations.All within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
