Description

Technical Field

[0001] This utility model relates to the field of crossarm stress monitoring, specifically to crossarm stress monitoring hardware. Background Technology

[0002] A crossarm is an angle iron fixed horizontally at the top of a power pole. It is mainly used to support overhead power lines. Its function is not only to support signal lines and insulators, but also to ensure that signal lines maintain a safe distance and prevent short circuits. As an important component of power poles, the crossarm undertakes the important tasks of fixing power line equipment, supporting insulator strings, and bearing power loads.

[0003] In power transmission systems, crossarms are crucial components supporting signal lines, and their stress state directly affects the safe and stable operation of the lines. However, traditional methods for monitoring crossarm stress mainly rely on periodic manual inspections and limited online monitoring devices. These methods suffer from problems such as untimely monitoring, inaccurate data, and inability to reflect crossarm stress changes in real time. Especially under complex and ever-changing natural environments and ever-increasing power loads, the stress conditions borne by crossarms are even more complex, and traditional monitoring methods are no longer sufficient to meet the high requirements of modern power grids for safety and reliability. Utility Model Content

These methods suffer from problems such as untimely monitoring, inaccurate data, and inability to reflect crossarm stress changes in real time. Especially under complex and ever-changing natural environments and increasing power loads, the stress conditions borne by the crossarm are even more complex, and traditional monitoring methods can hardly meet the high requirements of modern power grids for safety and reliability. This utility model proposes a crossarm stress monitoring fitting.

Signal lines are fixedly connected to the bottom of each surface strain gauge, with opposite ends of each signal line penetrating to the inner wall of the housing. Two data acquisition units are fixedly installed on the inner wall of the housing. The input end of each data acquisition unit is electrically connected to the output end of the surface strain gauge.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0024] The following is in conjunction with the appendix Figure 1-6 This application will be described in further detail.

[0025] This application discloses a crossarm stress monitoring fitting. (Refer to...) Figures 1-6 The stress monitoring fitting for the crossarm includes a mounting plate 1, an angle iron crossarm 4 fixedly connected to one side of the mounting plate 1, a support plate 3 fixedly installed to one side of the mounting plate 1, a connecting column 17 fixedly connected to one side of the support plate 3, a housing 7 fixedly connected to one side of the connecting column 17, and a stress monitoring mechanism 2 provided on the inner wall of the housing 7.

[0026] The stress monitoring mechanism 2 includes two surface strain gauges 201. Both surface strain gauges 201 are fixedly connected to both sides of the bottom of the angle iron crossarm 4. Signal lines 202 are fixedly connected to the bottom of each surface strain gauge 201. The opposite ends of the two signal lines 202 pass through the inner wall of the housing 7. Data acquisition units 204 are fixedly installed on the inner wall of the housing 7. There are two data acquisition units 204. The input end of the data acquisition unit 204 is electrically connected to the output end of the surface strain gauge 201. A transmission unit module 203 is fixedly connected to the inner wall of the housing 7. The input and output ends of the transmission unit module 203 are bidirectionally electrically connected to the input and output ends of the two data acquisition units 204.

[0027] Reference Figure 1 , Figure 3 and Figure 5 A protective cover 8 is movably connected to one side of the housing 7. A rotating shaft 16 is fixedly connected to the top of the protective cover 8. There are two rotating shafts 16. The connection between the protective cover 8 and the housing 7 is rotatably connected through the rotating shafts 16. An auxiliary block 9 is fixedly connected to one side of the protective cover 8. There are two auxiliary blocks 9. By setting two auxiliary blocks 9, it is convenient for users to open the protective cover 8 to inspect or operate the components inside the housing 7. The protective cover 8 is made of a material that matches the housing 7. It has good sealing and protection properties and can effectively prevent external factors such as dust and moisture from damaging the components inside the housing 7.

[0028] Reference Figure 3 and Figure 4An iron block 11 is fixedly connected to the bottom of the housing 7, and a magnet 12 is fixedly connected to one side of the protective cover 8. One side of the magnet 12 is in close contact with one side of the iron block 11. By setting the magnet 12 and the iron block 11 in close contact, the protective cover 8 can remain stable in the closed state, effectively preventing the protective cover 8 from being accidentally opened due to external vibration or collision, thereby further ensuring the safety and stability of the internal components of the housing 7. At the same time, this design also makes it easy for users to quickly check whether the protective cover 8 is in a fully closed state, improving the convenience and reliability of use.

[0029] Reference Figure 1 , Figure 2 , Figure 3 and Figure 5 Two ultrasonic bird repellers 6 are fixedly installed at the bottom of the housing 7. By setting two ultrasonic bird repellers 6, the surrounding birds can be effectively driven away, preventing birds from staying or nesting near the stress monitoring hardware of the angle iron crossarm 4. This prevents bird activities from interfering with or damaging the monitoring hardware, ensuring the normal operation of the monitoring hardware and the accuracy of the monitoring data. At the same time, the ultrasonic bird repellers 6 use an environmentally friendly and pollution-free method to drive away birds, and will not have an adverse impact on the surrounding environment.

[0030] Reference Figure 3 and Figure 4 A connecting plate 10 is fixedly connected between the two ultrasonic bird repellers 6 on opposite sides. The inner wall of the connecting plate 10 is provided with a mounting post 15. The use of the connecting plate 10 and the mounting post 15 together can enhance the connection stability between the two ultrasonic bird repellers 6, ensuring that they maintain a relatively fixed position during operation and will not shift or shake due to external factors. At the same time, the mounting post 15 can increase the stability and firmness of the connecting plate 10 and the housing 7 after connection.

[0031] Reference Figure 4 The inner wall of the mounting column 15 is movably connected with two locking blocks 14. The top of the locking blocks 14 contacts the bottom of the connecting plate 10. A spring 13 is fixedly connected between the opposite sides of the two locking blocks 14. By setting the locking blocks 14 and the spring 13 to work together, the locking blocks 14 can move flexibly within the mounting column 15. At the same time, the locking blocks 14 will not detach when moving within the mounting column 15. When it is necessary to install or remove the connecting plate 10, the locking blocks 14 can be retracted inward by compressing the spring 13, so as to easily connect or separate the connecting plate 10 from the mounting column 15. Under normal working conditions, the elasticity of the spring 13 will cause the locking blocks 14 to extend outward and press tightly against the bottom of the connecting plate 10, further enhancing the connection stability between the connecting plate 10 and the mounting column 15, and effectively preventing the connecting plate 10 from loosening or falling off during operation.

[0032] Reference Figure 2 and Figure 5 Both sides of the support plate 3 are provided with threaded rods 5. The support plate 3 and the mounting plate 1 are connected by threaded rods 5. By setting threaded rods 5, the support plate 3 and the mounting plate 1 can be connected and disassembled conveniently and quickly, and the connection is firm and reliable. The design of threaded rods 5 enables the support plate 3 to withstand greater stress after installation, and it is not easy to loosen or shift. At the same time, this threaded connection method also facilitates the maintenance and replacement of the support plate 3, improving the flexibility of use and maintenance efficiency of the entire device.

[0033] Working Principle: To better understand the stress changes of the angle iron crossarm 4, when the angle iron crossarm 4 is subjected to stress, it will undergo minute deformations. The surface strain gauge 201 installed at the bottom of the angle iron crossarm 4 can accurately sense these minute changes and convert them into electrical signals. These electrical signals are transmitted to the data acquisition unit 204 through the pre-set signal line 202. The data acquisition unit 204 performs detailed analysis and processing of the received electrical signals, converting them into data that intuitively reflects the magnitude and changes of stress in the angle iron crossarm 4. Subsequently, this data is transmitted through the transmission unit module 203. Operators can view the stress state of the angle iron crossarm 4 in real time and clearly through an external display device, enabling analysis and research on the stress change trend of the angle iron crossarm 4, providing valuable information for equipment maintenance and safe operation. According to the requirements, in order to prevent birds from staying or nesting near the stress monitoring hardware of the angle iron crossarm 4, and to prevent bird activities from interfering with or damaging the monitoring hardware, and to ensure the normal operation and data accuracy of the stress monitoring mechanism 2, an ultrasonic bird repeller 6 needs to be installed. During installation, the connecting plate 10 is inserted into the mounting post 15. When the connecting plate 10 contacts the two locking blocks 14, the locking blocks 14 slide against the inner wall of the mounting post 15 under force, while squeezing the spring 13. When the connecting plate 10 moves to contact the housing 7, the locking blocks 14 separate from the connecting plate 10. Under the elastic action of the spring 13, the locking blocks 14 return to their original position, thereby fixing the connecting plate 10 and enhancing the overall stability and firmness of the connecting plate 10 and the ultrasonic bird repeller 6. When the user needs to open the protective cover 8, the moving auxiliary block 9 drives the protective cover 8 to rotate under the action of the rotating shaft 16, and the protective cover 8 can be opened.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
