Description

Technical Field

[0001] The present application relates to the technical field of high-power broadcast communications, and in particular to an insulating device for the bottom of a parallel feed body of a medium-wave parallel-fed antenna. Background Art

[0002] A medium-wave parallel-fed antenna consists of a quadrilateral antenna mast and a parallel feeder. The mast height typically ranges from 90 to 150 meters. There are 12 or 16 parallel feeders, extending from the center of the quadrilateral mast between 50 and 80 meters from the center. There are two or four parallel feeders on each side of the mast. The mast stands vertically on the ground, with the parallel feeder attached to a specific location in the center of the mast and its lower end connected to the ground with a tension anchor.

[0003] Insulators are located approximately 3 to 5 meters above the ground at the bottom of the parallel feeder, insulating each parallel feeder from the ground. The parallel feeder is tilted from a specific location in the middle of the mast to the ground, with an angle of 8 to 10 degrees between it and the vertical polygonal mast. A wire extends from 0.3 to 0.4 meters above the insulator at the bottom of each parallel feeder. The other end of the wire converges parallel to a point in the center of the quadrilateral mast, serving as the antenna feed point.

[0004] Currently, the bottom of the feeder body of a medium-wave parallel-fed antenna is typically insulated by connecting a ceramic insulating rod. This rod is typically made by processing the ends of a 95% porcelain high-frequency insulating rod and then bonding it to a pull-rope fitting. However, due to the characteristics of ceramic insulating rods, such as being vulnerable to impact, prone to breaking when stretched, complex processing and high processing costs, the feeder body in a medium-wave parallel-fed antenna is long and subject to large expansion forces. This expansion force also varies with wind speed, resulting in high tension exerted by the feeder body on the high-frequency insulating rod, causing fatigue fracture of the ceramic insulating rod. The rod is also prone to breakage due to bumps and collisions during transportation and suspension. Furthermore, the use of ceramic insulating rods requires processing of both ends of the insulating rod, which is complex and expensive.

[0005] Therefore, it is necessary to provide a new technical solution to improve one or more problems existing in the above solutions. Utility Model Content

[0035] In this exemplary embodiment, a medium wave parallel-fed antenna parallel-fed body bottom insulation device is first provided. Figures 1 to 6 As shown in, the device for insulating the parallel feed body of the medium wave parallel fed antenna includes: an insulator 100, a pressure plate mechanism 200 and a pulling plate mechanism 300; wherein, the insulating mechanism 100 includes two insulators 110 and a connecting plate 120, and the two insulators 110 are located on both sides of the connecting plate 120 and are connected by the connecting plate 120; the pressure plate mechanism 200 includes a first pressure plate 210 and a second pressure plate 230; the insulating mechanism 100 is arranged between the first pressure plate 210 and the second pressure plate 230; the pulling plate mechanism 300 includes a first pulling plate 310 and a pulling plate screw 320; the first pulling plate 310 is fixedly connected to the connecting plate 120 through the pulling plate screw 320.

[0037] It should be noted that, through the structure of the above scheme, a slender ceramic rod subjected to tension in the prior art can be replaced with two ceramic tubes that are thicker and shorter respectively and subjected to compression, thereby greatly improving the bearing capacity of the insulating device. Moreover, through the structure of the above scheme, the ceramic tube does not need to bear tension, and its two ends do not need to be processed, and can be simply bonded, thereby reducing the processing cost of the ceramic tube.

[0038] Optionally, the limiting cap 112 is bonded to the ceramic tube 111 by resin glue.

[0039] Optionally, a high-frequency insulating cap is hung on the outer surface of the ceramic tube 111, with a length of 80 mm, an outer diameter of 60 mm, and an inner diameter of 30 mm. The limiting cap is a circular structure made of δ16 alloy aluminum plate, with a depression on one side for embedding the insulator 1, with a diameter of 72 mm and a depth of 8 mm.

[0041] It should be noted that the two ends of the two connected insulators 110 are respectively connected to the inner sides of the first pressing plate 210 and the second pressing plate 230 of the pressing plate mechanism 200 through the limiting caps 112, so there is no need to process the two ends of the ceramic tube 111 in the insulator 110.

[0042] In one embodiment, the limiting cap 112 has a limiting block on a side away from the ceramic tube 111 , the connecting plate 120 has a first limiting hole 121 , and the limiting block engages with the first limiting hole 121 .

[0049] Optionally, the diameter of the lifting hole of the first lifting lug plate 211 is 40 mm.

[0050] It should be noted that the first lug plate 211 is welded to the lug pressure plate 212 to form a T-shaped structure. The first lug plate 211 is used to connect to the upper end of the pull wire at the bottom of the medium wave parallel feed body.

[0051] In one embodiment, the first pull plate 310 includes: a second lug plate 311 and a lug pull plate 312 ; the second lug plate 311 is fixedly connected to an end of the lug pull plate 312 away from the insulator 110 .

It is fastened by nuts. The two pressure plate screw rods 220 can protect the insulator 110 and prevent collision.

[0056] In one embodiment, the first pressing plate 210, the second pressing plate 230 and the two pressing plate screw rods 220 of the pressing plate mechanism 200 form a first rectangular metal frame; the first pulling plate 310 and the two pulling plate screw rods 320 of the pulling plate mechanism 300 and the connecting plate 120 form a second rectangular metal frame, and the first rectangular metal frame and the second rectangular metal frame are vertically arranged.

When the first lug plate 211 and the second lug plate 311 are subjected to thrust, the thrust is converted into pressure exerted by the connecting plate 120 and the first pressure plate 210 on the insulator 110.
