Description

Technical Field

[0002] Transmission line equivalent icing monitoring is to monitor the icing condition of the conductor in real time so that the power department can deal with the icing condition in time. When the transmission line equivalent icing monitoring is performed, a tension sensor needs to be installed at the end of the conductor when the transmission line is installed. The tension value after icing is monitored by the tension sensor. The existing tension sensor is a device used to monitor the tension generated by the conductor after icing during the transmission line equivalent icing monitoring. The tension sensor is easy to strengthen the fixed installation when in use, and is stably installed and monitored, thereby improving the enhanced fixation of the tension sensor body during the transmission line equivalent icing monitoring and the accuracy of monitoring tension.

[0003] When the existing tension sensor monitors the tension of the conductor during the equivalent ice coverage monitoring of the transmission line, the fixing piece at the end of the conductor is directly connected to the bottom end of the tension sensor, and then the bolts are penetrated into the inside of the fixing hole to reinforce the installation. Therefore, after the bolts fix the bottom end of the tension sensor to the fixing piece at the end of the conductor, it is not convenient to reinforce the installation of the bolts, so that when the tension sensor is subjected to the tension of the conductor, the fixed end and the conductor will shake and become unstable. Long-term shaking can easily cause the bolts to loosen or even fall off, thereby affecting the problem of strengthening the fixation of the tension sensor during the equivalent ice coverage monitoring of the transmission line. For this reason, the utility model proposes a tension sensor device for equivalent ice coverage monitoring of the transmission line. Utility Model Content

When the tension sensor body 100 is fixedly installed and exposed to the outside for use, and when it is touched by external objects, the buffer protection mechanism buffers and protects the outer surface of the tension sensor body 100 to reduce the impact and improve the protection effect of the tension sensor body 100 when monitoring the equivalent ice cover of the transmission line.

[0031] In order to facilitate the buffering and protection of the outer surface of the tension sensor body 100 during monitoring and use after installation through the buffering and protection assembly, in the present embodiment, preferably, the buffering and protection assembly includes an upper buffer cover 1011 arranged on the upper surface of the main structure 101, a lower buffer cover 1012 is arranged on the lower surface of the main structure 101, and buffer springs 1013 are welded to the inner surfaces of the upper buffer cover 1011 and the lower buffer cover 1012.

At this time, when the surfaces of the upper buffer cover 1011 and the lower buffer cover 1012 are impacted, the buffer spring 1013 is deformed and buffered to reduce the impact and is not easily damaged.

[0033] Working principle and use process of the utility model: When using the tension sensor device for monitoring equivalent ice coverage of power transmission lines, firstly fix the mounting end 102 with one end of the outside world, then connect the bottom end of the fixed end 104 to the wire end fixture of the external power transmission line, and the bolts penetrate the inside of the fixing hole 105 to fix the fixed end 104 with the external wire end fixture, so as to fix the tension sensor body 100 with the end of the wire, and connect the end of the connection port 103 to the external monitoring equipment for wire connection, so as to facilitate the stress and tension test of the main structure 101 when the wire is subjected to tension;

[0034] Then, when the tension sensor body 100 is installed, the bolt passes through the interior of the fixing hole 105 to fix the fixed end 104 to the fixing piece at the end of the external wire. When the bolt is in the fixing hole 105, it is threadedly connected with the inner surface of the internal thread reinforcement plate 1051. At the same time, the bottom end of the fixed end 104 is reinforced by the reinforcing connecting plate 1052 during fixation. The locking nut 1053 is loosened again, and the threaded rod 1054 is rotated inside the reinforcing connecting plate 1052. When the threaded rod 1054 rotates, the rotating ring rotates inside the movable plate 1055, so that when the threaded rod 1054 rotates, the movable plate 1055 is moved. When the moving plate 1055 moves, it drives the reinforcement tooth plate 1059 to slide inside the moving adjustment groove 1056, and then drives the limit block 1057 to limit the inner position of the limit groove 1058, so that the reinforcement tooth plate 1059 can move stably and bite on the outer surface of the bolt for reinforcement installation, and the locking nut 1053 is rotated again to reinforce the installation of the screwed threaded rod 1054, so that the fixed end 104 and the wire end of the transmission line are strengthened and fixed, and the connection is more stable and not easy to loosen when subjected to tension shaking, and the tension monitoring is stably performed, thereby improving the enhanced fixity of the tension sensor body 100 during the equivalent ice coverage monitoring of the transmission line;

[0035] Finally, before the installation of the tension sensor body 100, the upper buffer cover 1011 and the lower buffer cover 1012 are closed on the outer surface of the main structure 101. After closing, the screw 1015 is rotated to penetrate the interior of the two fixing plates 1014 to fix the upper buffer cover 1011 and the lower buffer cover 1012 to be fixedly connected. After fixed installation, the end of the buffer spring 1013 is tightly pressed and contacted with the surface of the main structure 101. At this time, when the tension sensor body 100 is installed for tension monitoring and exposed to the outside world for use and is impacted, when the object hits the surface of the upper buffer cover 1011 and the lower buffer cover 1012 and the buffer spring 1013 is subjected to force, the buffer spring 1013 is deformed to elastically buffer the upper buffer cover 1011 and the lower buffer cover 1012, which is easy to reduce the impact, convenient for buffering protection, and improves the protection effect of the tension sensor body 100 during the equivalent ice coverage monitoring of the transmission line.
