Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of antennas, and particularly relates to an asymmetric reconfigurable hexagonal long-wave antenna. BACKGROUND

[0002] Long-wave antennas are usually used in the fields of submarine communication, navigation, time service, etc., and common forms include single-tower umbrella antennas, multi-tower multi-umbrella antennas, valley antennas, etc., which are characterized by large land occupation, large radiation range, strong penetration, high antenna height, etc. An antenna is usually composed of a support body and a top load, and has a T-shaped or Γ-shaped structure, and the support body is usually a mast tower or a mountain body with a height of more than 200 meters; the top load is usually composed of a wire to form a rectangular or diamond-shaped net structure and is suspended and fixed on the support body. At present, the existing long-wave antennas mainly adopt single-tower umbrella antennas and valley antennas.

[0003] A single-tower umbrella antenna is mainly composed of one 250-meter insulating tower and a plurality of single-wire umbrella top loads, one end of the top load is connected to the top end of the insulating tower, and the other end is connected to a ground anchor on the ground through a steel wire rope, and the shape is similar to a rib of an umbrella. In order to ensure balanced force bearing, the antenna must have a central symmetric structure and be constructed on flat or gently sloping land, and the insulating tower and the single-wire top load form a radiator to broadcast signals.

[0004] A multi-tower multi-umbrella antenna is usually composed of four towers and a symmetric quadrilateral wire net as a group, and four or six groups form an antenna system, and the single group and the whole antenna have a symmetric structure and are constructed on flat land.

[0005] A valley antenna must rely on two parallel peaks, and a plurality of parallel wire top loads are designed in the valley, and the antenna has a rectangular structure on the ground projection plane; due to the limitation of the terrain, two rows of parallel mast towers can also be designed in the plain area, which is similar to the valley form, and parallel wire top loads are designed between the two rows of towers.

[0006] These large long-wave antennas have special requirements for the terrain and landform of the construction site, and once the design and construction are completed, the electrical characteristics and structural characteristics are fixed and cannot be adjusted.

[0007] At present, single-tower umbrella antennas, multi-tower multi-umbrella antennas, and valley antennas are mainly limited by the position of the antenna, the constraint of the terrain and landform, etc., and the main shortcomings are as follows:

[0008] 1. The single-tower umbrella antenna has a small spatial volume and a small power capacity, and cannot meet the requirements of large power and super-long distance communication;

[0009] 2. The valley antenna must select a valley formed by two parallel peaks as a support carrier;

[0010] 3. The antenna composed of multiple towers and multiple groups of top wires has a rectangular structure or a symmetric structure on the plane and is only suitable for construction in plain areas.

[0011] 4. The antenna top loads are all fixed in shape, which makes the antennas poorly adaptable to extreme conditions. Furthermore, the antenna parameters are fixed and cannot be reconstructed structurally to adjust the antenna electrical parameters after construction. Summary of the Invention

[0012] To overcome the shortcomings of existing technologies, this invention discloses an asymmetric reconfigurable hexagonal longwave antenna, comprising an asymmetric hexagonal heterogeneous wire mesh, an insulated mast over 250 meters high, six edge-grounded masts, and six multi-mode control systems. The insulated masts and the asymmetric hexagonal heterogeneous wire mesh form the radiator of the longwave antenna, while the edge-grounded masts support the asymmetric hexagonal heterogeneous wire mesh. The multi-mode control systems achieve morphological control and adaptive adjustment of the asymmetric hexagonal heterogeneous wire mesh. The edge-grounded masts are arranged at arbitrary positions around the insulated mast, with their heights consistent with those of the insulated mast. This invention allows for adjustment of the antenna's spatial volume capacity according to requirements, achieving high power capacity, high radiation efficiency, and ultra-long radiation distance, improving performance parameter redundancy, and reducing the technical risks of large-scale longwave antenna engineering construction.

[0013] The technical solution adopted by this invention to solve its technical problem is as follows:

DETAILED DESCRIPTION

[0032] The application is further illustrated below in combination with the drawings and examples.

[0033] The design scheme adopted by the application is: under any terrain, the asymmetric hexagonal heterogeneous wire net is adopted for the top load of the long wave antenna; the support body adopts seven 250-meter or more guyed masts, including six edge ground masts and one center area insulation mast; the insulation mast and the wire net jointly form the antenna radiator, and the multi-modal control system is arranged near the bottom of the six edge masts to pull the top load tail line.

[0034] The application is not restricted by the terrain conditions and can be constructed in various geological environments such as plains, hills and mountains. After the center mast position is determined, six edge mast towers are distributed around the center mast position as the reference, and the absolute height of the top of the seven mast towers is consistent, and the top load height and the space coverage volume can be expanded according to the requirements. The guyed mast tower can solve the asymmetric stress and the uneven stress problem caused by the terrain factors by adjusting the tension of the guyed masts in different directions.

[0035] As Figure 1 , Figure 2The diagram shows the overall elevation and plan views of the asymmetric reconfigurable hexagonal longwave antenna structure. The antenna consists of one asymmetric hexagonal heterogeneous wire mesh 1, one insulating mast 2 exceeding 250 meters in height, six edge grounding masts 3 exceeding 250 meters in height, and six multimode control systems 4. The insulating masts and the hexagonal heterogeneous wire mesh form the radiating element of the longwave antenna, while the edge grounding masts support the wire mesh. The multimode control systems enable morphological control and adaptive adjustment of the hexagonal antenna wire mesh. The overall antenna structure can be deployed in various terrain conditions such as slopes, hills, mountains, swamps, and tidal flats. Once the position of the central insulating mast is determined, the edge grounding masts can be placed in any surrounding location. Only the height of the edge grounding masts needs to be adjusted to ensure that all vertices and the center point of the wire mesh are at the same height.

[0036] like Figure 3 As shown, the insulated mast 2 adopts a guyed mast structure, and the mast body 5 has a triangular truss structure in cross section; the fiber rope 6 is a steel wire rope, with a total of 15 ropes distributed in three sides and five layers, one end of which is connected to the mast body and the other end of which is connected to the ground concrete foundation 9; the mast bottom is equipped with a base insulator 8, and the fiber ropes are equipped with insulator strings 7 at both ends to insulate the mast body from the ground and realize its radiating function.

[0037] like Figure 4 As shown, the insulated mast body is a triangular truss structure composed of steel pipe chords 10 and web members 11; the upper and lower ends of the fiber rope 6 are connected to the mast body and concrete foundation 9 by alloy sleeves 12, thereby ensuring the mast's upright stability; the fiber rope insulates the mast body from the ground through two insulator strings 7 at the top and bottom, which consist of hardware 13 and disc insulators 14. Figure 5 As shown, the mast is insulated from the ground by the cylindrical base insulator 8, which also provides support for the mast.

[0038] The edge mast 3 has the same structure as the insulated mast 1, except that the mast root and the fiber rope do not contain base insulators or insulator strings, and are directly connected to the concrete foundation to achieve the grounding effect.

[0039] like Figure 2 As shown, the top-load network is an asymmetric arbitrary hexagonal network composed of six side suspension cables and 28 top wires. The span of any opposite side of the hexagon can reach 2-3 km. The network is connected to the central tower on one side of the central mast, thus forming a complete long-wave antenna radiator together with the central insulated mast, achieving high power capacity, high radiation efficiency, and ultra-long radiation distance. Figure 6 As shown, this is a partial view of the hexagonal vertex. On one side of the side tower, the insulator string 7 intersects at a point, and the tail wire connects to the top of the edge tower, which realizes the support of the top load network while ensuring the electrical insulation between the top load and the edge mast.

[0040] like Figure 7As shown, a schematic diagram of the multi-modal control system 4 is composed of a force-effect mode converter 15, a wire net control tail wire 16, a guide conversion pulley 17, and an adaptive traction device 18; the length of the wire net control tail wire 16 is adjusted by the adaptive traction device 18 to realize coupling control of the hexagonal wire net shape, change the top load shape and height, and thus change the antenna electrical static capacitance, radiation efficiency, power capacity and other parameters.

[0041] During maintenance of the antenna top load, the wire net is adjusted to rise and fall by the adaptive traction device 18, and the antenna top load is lowered to the ground for detection and maintenance.

[0042] According to the maximum bearing capacity of the wire net, a threshold is set for the force on the umbrella-shaped wire net tail wire by the adaptive traction device 18. When encountering typhoon and other severe weather, if the force on the tail wire is greater than the threshold, the traction device can adaptively pay out the wire until the force on the tail wire is less than the threshold to stop, thereby realizing the adaptive protection function of the top wire net.

[0043] The antenna radiation top wire and the six edge suspension cables of the present application form an arbitrary hexagonal net structure, and the center insulating mast constitutes a long wave antenna umbrella-shaped radiator. The six edge ground mast supports and ensures the contour shape of the wire net, and the antenna occupies an area not limited by the terrain. After the position of the center mast is determined, the six edge masts are arranged arbitrarily with the center mast as the center. The guyed mast balances the horizontal load generated by the terrain and the top wire net through three-party fiber ropes, and ensures the force balance of the overall structure. The present application designs a multi-modal control system at the edge mast, realizes coupling control of the hexagonal wire net shape through the tail wire, changes the top load shape and height, and thus changes the antenna electrical static capacitance, radiation efficiency, power capacity and other parameters. The traction device can adaptively pay out the wire according to the tail wire threshold, thereby realizing the adaptive protection function of the top wire net, and adapting to various different working conditions and severe environments.
