Description

Technical Field

[0001] The utility model belongs to the technical field of building detection, and in particular relates to a vibration monitoring sensor arrangement device for a building steel structure. Background Art

[0002] Optical fiber sensing technology is widely used in aviation, civil engineering, deep-sea engineering, oil extraction, and geological exploration due to its advantages of electrical insulation, corrosion resistance, fire and explosion resistance, easy network integration, long-term stability, absolute measurement, and high sensitivity. In the measurement of engineering structure parameters, optical fiber sensors will inevitably have the problem of interaction between the matrix structure and the sensing optical fiber element. This problem is directly related to whether the optical fiber sensor can effectively and accurately extract the characteristic parameters of the engineering structure. Accurate parameter extraction has a very direct and critical guiding role in optical fiber sensing technology and its application in optics and optoelectronics. Due to the brittle characteristics and weak shear resistance of the constituent materials, optical fiber sensing elements usually need to be encapsulated and protected during the application process to adapt to the harsh construction and operation environment in the engineering field. When optical fiber sensors are used to measure structural deformation, the optical fiber needs to be desensitized and encapsulated to ensure its survival rate and the effectiveness and long-term stability of the measurement. Due to the existence of the optical fiber encapsulation protective layer, the deformation information of the measured structure needs to be transmitted to the sensing optical fiber through the intermediate medium layer. During the transmission of deformation information, the intermediate medium layer will receive part of the deformation information of the measured structure, resulting in the strain sensed by the optical fiber being smaller than the actual strain of the measured structure, thereby introducing a strain transmission error. For sensors with different constraint types, the transmission error can be eliminated through calibration experiments, improved calibration experiments or strain transfer theory modeling analysis.

[0003] Currently, when fiber optic sensors are used for building vibration detection, it is usually necessary to destructively drill holes in the building, then install the fiber optic sensors, and then start the building vibration detection. However, doing so will destroy the original structural integrity of the building and affect the main structure of the building. Utility Model Content

[0050] It should be noted that the equipment structure and drawings of the utility model mainly describe the principle of the utility model. In terms of the technology of the design principle, the settings of the power mechanism, power supply system and control system of the device are not fully described. On the premise that the technical personnel in this field understand the principle of the above-mentioned utility model, the details of its power mechanism, power supply system and control system can be clearly known. The control method of the application document is automatic control through a controller, and the control circuit of the controller can be realized by simple programming by technical personnel in this field.

[0051] The standard parts used therein can all be purchased from the market and can be customized according to the instructions and drawings. The specific connection methods of each part adopt conventional means such as mature bolts, rivets, welding, etc. in the prior art. The machinery, parts and equipment all adopt conventional models in the prior art, and the structures and principles of the components known to technical personnel in this field can be known by these technical personnel through technical manuals or through conventional experimental methods.

[0052] The working principle of the vibration monitoring sensor arrangement device for building steel structure provided by the utility model embodiment is as follows:

[0053] First, the mounting base plate 1 is used as the foundation of the entire device, and the device can be conveniently fixed on the building steel structure through the mounting ears 15 and fixing bolts 16 on both sides thereof. Since the fixing bolts 16 are threaded, the damage to the wall is small, and even when disassembling, the wall will not be damaged too much.

[0054] The groove on the upper surface of the mounting substrate 1 is designed to accommodate the rubber clip 2. The rubber clip 2 has a certain elasticity and toughness, and can fit tightly in the groove. At the same time, the clip 3 on the outside can be locked with the mounting substrate 1 to prevent it from falling off. The inner stopper 4 of the rubber clip 2 is used to fix the optical fiber sensor 5 to ensure that the optical fiber sensor 5 can remain stable in a vibration environment.

[0055] During the installation of the device, the staff can position and fix the substrate through the alignment plate 10. The design of the first spring 11 and the first limit block 12 inside the alignment plate 10 allows the first limit block 12 to be compressed and compress the first spring 11 when the two mounting substrates 1 are close to each other during the installation process. When the two mounting substrates 1 are completely docked, the first spring 11 will return to its original state and push the first limit block 12 to move outward, thereby locking the two mounting substrates 1 and achieving a fixing effect.

[0056] After installation, the cover plate 7 cooperates with the rectangular slot 9 on the mounting substrate 1 through the connecting plate 8 on its lower surface to close the upper part of the mounting substrate 1. At the same time, the second spring 13 and the second stopper 14 inside the mounting substrate 1 also play a role in fixing the cover plate 7. When the cover plate 7 is placed in place, the second stopper 14 will be squeezed and compress the second spring 13. When the cover plate 7 is completely closed, the second spring 13 will return to its original state, push the second stopper 14 to move outward, and lock the cover plate 7.

[0057] One end of the optical fiber sensor 5 is connected to the DVS system 6, and is used to transmit the collected vibration signal to the DVS system 6 for processing and analysis. The DVS system 6 can determine the vibration state of the building steel structure based on the received signal, thereby realizing health monitoring of the steel structure.

[0058] The vibration monitoring sensor arrangement device for building steel structures provided by the utility model embodiment realizes stable installation and efficient monitoring of sensors through a series of ingenious structural designs, providing strong technical support for health monitoring of building steel structures.

[0059] The above description is only a specific implementation method of the present invention, but the protection scope of the present invention is not limited thereto. Any modification, equivalent substitution and improvement made by any technician familiar with the technical field within the technical scope disclosed by the present invention and within the spirit and principle of the present invention shall be covered by the protection scope of the present invention.
