Technical Field

[0001] The utility model relates to the field of cable internal force measuring devices, in particular to a cable force monitoring device for a cable net curtain wall of a high-rise building. Background Technique

[0002] The cable net structure in the cable net glass curtain wall serves as a key load-bearing member, playing an important role in bearing the self-weight of the curtain wall and the external wind load. Among them, the cable force of the cable is the core element to ensure the normal operation and stability of the cable net structure.

[0003] However, the cable force of the cable will gradually weaken due to various factors such as material aging, structural deformation, or component damage, which poses a potential threat to the bearing capacity of the cable net structure. Therefore, during the use of the cable net structure, it is particularly important to monitor the cable force of the cable.

[0004] Regularly detecting the cable force of the cable is a direct basis for analyzing whether the cable is in a normal operating state. Detecting the cable force can timely reflect the working state of the cable, which is of great significance for timely taking economic and effective countermeasures and scientifically and effectively maintaining the cable. It is an important content of the cable health and safety monitoring.

[0005] However, for the measurement of the cable net structure of high-rise buildings, when measuring the cable force, due to working at heights, there are problems such as inconvenient measurement and low safety of the staff. Moreover, regularly measuring the cable force of the cable net structure cannot timely feedback the change of the cable force, and the effectiveness of the measurement is poor. Summary of the Utility Model

[0033] Embodiment 1

[0034] As Figure 1 and Figure 2 shown, this embodiment provides a cable force monitoring device for a cable net curtain wall of a high-rise building, including a strain gauge 1, a first fixer 2, a second fixer 3, a third fixer 4, a fourth fixer 5, a communication component 6, and a built-in power supply 7. The first fixer 2, the second fixer 3, the third fixer 4, and the fourth fixer 5 are all arch structures. A semi-circular card slot 9 matching the shape of the cable 8 is provided on one side of the arch structure, and an installation plane 10 is provided on the opposite side.

[0035] The cable 8 is stuck in the semi-circular card slot of the arch bridge structure. The first fixator 2 is connected to the second fixator 3 and symmetrically distributed on both sides of the cable 8. The third fixator 4 is connected to the fourth fixator 5 and symmetrically distributed on both sides of the cable 8. The communication component 6 and the built-in power supply 7 are both fixed on the installation plane. The built-in power supply 7 is respectively connected to the strain gauge 1 and the communication component 6;

[0036] The distance between the first fixator 2 and the third fixator 4 corresponds to the length of the strain gauge 1. Both ends of the strain gauge 1 are respectively fixed on the installation planes of the first fixator 2 and the third fixator 4. The strain gauge 1 is connected to the communication component 6, and the communication component 6 is wirelessly connected to the remote display terminal.

[0037] Working principle: The first fixator 2 and the second fixator 3 are stuck on the cable through the semi-circular card slot and connected and clamped on the cable. The fixing methods of the third fixator 4 and the fourth fixator 5 are the same as those of the first fixator and the second fixator. Then, the strain gauge 1, the communication component 6 and the built-in power supply are fixed on the installation plane of the arch bridge structure. During the service process of the cable net structure, the strain gauge 1 measures the deformation of the cable 8 in real time, and wirelessly transmits the measurement result to the remote display terminal through the communication component 6. The staff judges the cable force of the cable according to the measurement result.

[0038] By fixing the fixator of the arch bridge structure on the cable, and cooperating with the installation plane arranged outside the fixator, the strain gauge is fixed on the installation plane to measure the cable force in real time, and wirelessly transmit it to the remote display module through the communication module 6 for the staff to view. The installation plane arranged on the fixator of the arch bridge structure can avoid the situation that the surface of the cable is uneven, resulting in large measurement errors of the strain gauge, improving the measurement accuracy. Moreover, with the wireless transmission of the communication module, the cable can be monitored in real time and the measurement result can be feedback in real time, so that the problems of the cable can be found in time and the timeliness of the measurement can be ensured.

[0039] Among them, the installation planes of the first fixator 2 and the third fixator 4 are in the same plane, and this plane is parallel to the axis of the cable 8. The strain gauge 1 is parallel to the axis of the cable 8. The strain gauge 3 is a vibrating wire surface strain gauge and is connected to the communication component 6 by cable. The vibrating wire surface strain gauge is used to monitor the cable force.

[0040] The strain gauge 1 is fixed on a flat end face and is arranged parallel to the axis of the cable 8, improving the accuracy of the measurement result of the vibrating wire surface strain gauge.

[0041] Preferred embodiment, a protective shell 11 is provided outside the device. The protective shell 11 is a columnar structure and is fixed on the cable 8.

[0042] Among them, the protective shell 11 includes a first sub-shell 111 and a second sub-shell 112 that are snap-connected. The first sub-shell 111 and the second sub-shell 112 are symmetric semi-cylindrical structures, and the first sub-shell 111 and the second sub-shell 112 surround the outside of the cable force monitoring device.

[0043] A protective shell is provided on the outside of the cable force monitoring device to enclose the monitoring device, which can prevent the sensor from being eroded by environmental factors such as light, rain, and corrosive liquids, isolate the monitoring device from the outside world, ensure the normal use of the device, and extend the service life of the monitoring device.

[0044] Among them, the first fixture 2 and the second fixture 3 are connected by a double-headed bolt, and the third fixture 4 and the fourth fixture 5 are connected by a double-headed bolt. The fixture is fixed by double-row bolts. Compared with the existing solution, this solution can provide stronger fastening force to ensure that the fixture will not fall off due to the vibration of the cable net.

[0045] Furthermore, the communication component 6 is fixed on the installation plane of the second fixture 3. The built-in power supply 7 is fixed on the installation plane of the fourth fixture 5.

[0046] The fixture has a certain width, and an internal battery and a wireless module can be attached to its surface to realize the wireless transmission of sensor data. And the fixture has a large stiffness and is not easily deformed, which can ensure that when the cable undergoes longitudinal deformation, the sensor simultaneously generates the same longitudinal strain. Compared with the existing solution, the measurement accuracy is higher.

[0047] Specifically, the strain gauge 1, the communication component 6, and the built-in power supply 7 are all fixed on the installation plane of the arch bridge structure by bolts.

[0048] The cable force monitoring device has real-time feedback and warning functions. By adopting wireless transmission technology, the cable force data collected by the strain gauge 1 can be transmitted to the remote display terminal in real time. The terminal can evaluate the operating state of the cable net structure in real time according to these data. If the cable force is abnormal or there are potential risks, the terminal can immediately send out a warning signal so that the maintenance personnel can take measures to repair or reinforce in time to ensure the safety and stability of the cable net glass curtain wall.

[0049] The preferred specific embodiments of the present invention have been described in detail above. It should be understood that those of ordinary skill in the art can make many modifications and variations based on the concept of the present invention without creative labor. Therefore, all technical solutions that can be obtained by those skilled in the art in the technical field based on the concept of the present invention through logical analysis, reasoning, or limited experiments on the basis of the existing technology should be within the protection scope determined by the claims.
