[0002] In the fields of electric power, communication, bridge monitoring and the like, it is crucial to accurately monitor the tension or pressure of electric wires and cables, structural members and the like. Traditional tension or pressure monitoring methods usually rely on mechanical sensors or resistance strain gauges and the like, but these methods have many shortcomings. For example, mechanical sensors have complex structures, high installation and maintenance costs, and are susceptible to environmental factors, which can cause the measurement accuracy to decrease; although resistance strain gauges have high measurement accuracy, they are inconvenient to install and are susceptible to interference.

[0003] Currently, there is no pressure display for the anchoring wire (cable) hardware used on high-speed rail catenary lines. If the tension of the electric wires on the pole tower of the span can be monitored in real time, it can provide a safeguard for the operation of the line, especially under special weather conditions, such as icing, which can increase the load bearing capacity of the wires. If the icing condition on the wires can be known in the first time, measures can be taken in time to avoid the event of wire breakage and pole tower collapse. SUMMARY

[0026] It should be noted that in this document, the terms "comprise", "comprise" or any other variant thereof are intended to cover non-exclusive inclusion, so that a process, article or device including a series of elements not only includes those elements, but also includes other elements not explicitly listed or inherent to such a process, article or device. Without more limitations, the element defined by the statement "comprises a" does not exclude the presence of another identical element in the process, article or device comprising the element.

[0027] The utility model discloses an embodiment provides a pressure type wire hanging hardware, as shown in Figure 1 、 2 It comprises a buckle 1, a protruding head 2, an elastic metal film 3 and an electrode 4.

[0028] The buckle 1 is connected with the protruding head 2.

[0029] The elastic metal film 3 is arranged on the inner side of the buckle 1 and abuts against the protruding head 2 when the protruding head 2 is connected with the buckle 1, and is used for changing the resistance value after being deformed by the force from the protruding head 2.

[0030] The electrode 4 is connected with the elastic metal film 3 and is used for obtaining the resistance value of the deformed elastic metal film 3.

[0031] When the protruding head 2 is connected with the buckle 1, the elastic metal film 3 will be subjected to the force from the protruding head 2, which will cause the elastic metal film 3 to be deformed and change the resistance value. Through the connection between the electrode 4 and the elastic metal film 3, the resistance value after deformation can be accurately obtained, so as to indirectly measure the size of the pressure or tension received, thereby reflecting the bearing capacity of the wire.

[0032] In the resistance measurement, the electrode 4 is responsible for leading the current into and out of the elastic metal film 3. When the current passes through the elastic metal film 3, a voltage drop is generated, which is proportional to the resistance value and the current size. By measuring this voltage drop and current value, and then using Ohm's law (R = V / I, where R is the resistance, V is the voltage drop, and I is the current), the resistance value is calculated.

[0033] Further, it also includes a smart integrated transmission chip, which is arranged in the buckle 1 and connected with the electrode 4, for sending the acquired resistance value to the control end.

[0034] In this way, the measured resistance value (or converted into pressure / tension value) is transmitted to the computer or mobile phone in real time through the smart integrated transmission chip, providing the user with the ability to monitor the data in real time, facilitating data analysis, early warning and decision-making.

[0035] Illustratively, the smart integrated transmission chip adopts WS4460 model or XL4456 model.

[0036] Further, it also includes a power module connected with the smart integrated transmission chip, for providing stable working voltage for the smart integrated transmission chip.

[0037] Illustratively, the power module is a rechargeable battery or a solar power module, which can be conveniently charged or powered by solar energy.

[0038] The end of the lug 2 connected with the buckle 1 is provided with a bottom plate 21, and the curved surface of the bottom plate 21 facing the elastic metal film 3 is matched with the curved surface of the elastic metal film 3, and the other end is connected with the hanging point on the cross arm 5.

[0039] The curved surface of the bottom plate 21 is in more uniform contact with the elastic metal film 3, and the force applied to the elastic metal film 3 is also more uniform, so that the elastic metal film 3 deforms more uniformly, thereby accurately evaluating the stress condition of the wire.

[0040] The bottom plate 21 is a key component for connecting the lug 2 with the buckle 1, which plays a role in increasing the contact area and dispersing the pressure.

[0041] Through the bottom plate 21, the lug 2 can be more stably in contact with the buckle 1, reducing the wear or deformation caused by pressure concentration.

[0042] The bottom plate 21 is usually made of wear-resistant and corrosion-resistant materials, further improving the reliability and durability of the connection.

[0043] When the buckle 1 is connected with the lug 2, the bottom plate 21 is in abutment with the elastic metal film 3.

[0044] When the wire is subjected to external force, the bottom plate 21 can cause the elastic metal film 3 to deform, thereby determining the external force condition borne by the wire.

[0045] When the external force disappears, the elastic metal film 3 can quickly recover to the original state, ensuring the stability and safety of the power line.

[0046] By adjusting the tightness between the protrusion 2 and the buckle 1, the tension of the fitting can be adjusted, so that the fitting can better adapt to the needs of different lines, improving the flexibility and applicability of installation.

[0047] The protrusion 2 is of a detachable structure, facilitating replacement or maintenance.

[0048] The elastic metal film 3 is attached to the inner side of the buckle 1.

[0049] The inner side of the buckle 1 is provided with a space for accommodating the protrusion 2.

[0050] The intelligent integrated transmission chip is fixed on the buckle 1 through a binding belt or a sticky layer, improving the integration of the device, helping to reduce the occupied space, and facilitating installation and use in limited space.

[0051] The utility model can be applied to various occasions requiring measurement of pressure or tension, such as tension monitoring of electric wires and cables, health monitoring of bridge structures, etc.

[0052] The above is only a preferred embodiment of the utility model, and is not used to limit the protection scope of the utility model.
