Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of intelligent composite insulator core rods and relates to an intelligent composite insulator core rod and a production device thereof. Background Art
[0002] With the rapid development of economy, the demand for electric power resources in my country is also increasing year by year. Composite insulators play a key role in line operation. To ensure the safe operation of the line, it is necessary to monitor the line.
[0003] Composite insulator core rods are subject to variable stress, temperature changes, and the influence of natural disasters such as strong winds and rainstorms, which may lead to some mechanical and electrical damage factors. The intelligent composite insulator core rods can monitor the working conditions, temperature, variable stress, etc. of the composite insulators and their own status in real time by connecting communication devices at both ends of the optical fiber. The data collected by the signal device is accessed and recorded by the background data processing center through the wireless network, providing good data support for the analysis of the causes of composite insulator operation failures.
[0004] Currently, there is a need for an intelligent composite insulator core rod with optical fiber embedded inside. However, the existing process for embedding optical fiber is to cut a groove on the core rod and then place the optical fiber into the groove, which can easily damage the core rod. Some are located in the middle of the rubber layer outside the core rod and are not attached to the core rod. Since the core rod is the bearing component of the mechanical load of the load insulator, it can withstand and transmit related mechanical properties. The farther the optical fiber is from the core rod, the less likely it is to sense changes in the mechanical properties inside the core rod. Another method is to spirally wrap the optical fiber around the core rod, but this solution wastes optical fiber and is costly.
[0005] In addition, the structure of the intelligent composite insulator core rod production mold provided in the prior art includes a molding mold and a sampling cover, wherein the molding mold has a molding cavity inside, the upper end surface of the molding mold is provided with a glue injection port, and the front side wall or / and the rear side surface of the molding mold are provided with a sampling port for taking out the prefabricated core rod of the optical fiber composite insulator, and the glue injection port and the sampling port are both connected to the molding cavity; the sampling cover is detachably arranged at the sampling port, and the sampling cover is provided with a core rod hole for the core rod body to pass through and at least one optical fiber hole for the optical fiber to pass through, and the optical fiber hole is located outside the core rod hole. After vacuuming, the glue is poured into it from top to bottom, which is easy to be not fully filled, which is easy to cause the product to be scrapped and the yield rate is low. Summary of the invention

[0012] and a right end cover, wherein the right end cover and the left end cover are provided with a positioning hole one for passing the glass fiber core rod and a positioning hole two for passing the optical fiber, and the positioning hole one is connected with the positioning hole two; after the upper mold and the lower mold are closed, the right end cover and the left end cover are respectively installed on the left and right ends of the upper mold and the lower mold.
[0013] The center line of the overflow glue port is perpendicular to the center line of the upper semicircular through groove, one end of the overflow glue port is connected with the interior of the upper semicircular through groove, and the other end extends to the outside of the upper mold.
[0014] The center line of the glue injection port is perpendicular to the center line of the lower semicircular through groove, one end of the glue injection port is connected with the interior of the lower semicircular through groove, and the other end extends to the outside of the lower mold.

The bolts are installed in the corresponding bolt holes after passing through the clearance, and the right end cover, the left end cover, the upper die and the lower die are connected and fixed.
[0016] The lower semicircular through groove on the upper end surface of the lower die is concavely provided with sealing strip installation grooves at both ends, and sealing strips are installed in the sealing strip installation grooves.
[0017] An intelligent composite insulator core rod is produced by the intelligent composite insulator core rod production device described in the above technical solution, comprising a glass fiber core rod and an optical fiber. The outer wall of the glass fiber core rod is coated with an epoxy resin layer, the optical fiber is prefabricated in the epoxy resin layer, the optical fiber is attached to the outer wall of the glass fiber core rod, and the central axis of the optical fiber is parallel to the central axis of the glass fiber core rod.

For example, the temperature of the core rod will rise when struck by lightning, and the temperature can be sensed more quickly. Since the core rod is the bearing component of the mechanical load of the load insulator, it can withstand and transmit relevant mechanical properties. The optical fiber is close to the core rod, which makes it easier to sense the changes in the mechanical properties inside the core rod.
[0019] The device for producing the intelligent composite insulator core rod of the utility model first evacuates the glue material and then injects the glue from bottom to top, while injecting, the air inside the device is discharged, so the injection effect is better.
