Description

The invention relates to antenna technology, in particular to helical antennas, and can be used to create mobile communication nodes of the DKMV range operating at short stops.

Known spiral antenna of the DKMV range, made in the form of a four-way equiangular spiral, containing four isolated conductor antennas, a support mast made of separate sections with guy wires and mast anchors [1]. The disadvantage of an analog device is a long time to deploy the antenna.

Closest to the proposed solution is a spiral antenna of the DKMV range, made in the form of a four-way equiangular spiral, containing four antenna conductors isolated from each other, a support mast with guy wires and mast anchors; a metal case, inside of which there is an antenna power unit with high-frequency connectors for connecting feeders and antenna inputs, to which the upper ends of the antenna conductors are connected; the lower ends of the conductors are connected to one of the terminals of the resistive loads; four dielectric guy wires with clamps installed on them for fastening the antenna conductors, dielectric guy wires form a pyramidal structure, the top of which is located near the top of the mast, and the base is near the surface of the ground on which the mast is installed, these conductors are wound on the pyramidal structure with a certain step [2].

The disadvantage of the prototype device is also the large time that it takes to deploy the antenna, due to:

firstly, the fact that the mast is used as a support mast from separate sections, connected to each other using bolted connections, and the installation of all sections except the lower one requires the work of installers at a height and the use of hand winches and rigging tools to lift each section ;

secondly, since the spiral antenna is powered from the top of the mast, the metal housing in which the power unit is located must be located on the top of the mast. The installation of this body on the mast in a known design, the connection of high-frequency feeders to the connectors, as well as the antenna conductors to the antenna inputs mounted on the metal body, must be carried out by the installer at a height after the mast has been fully installed;

thirdly, the process of creating a pyramidal structure on which the antenna sheet is deployed requires a lot of time, since it is also possible only after the mast is fully installed. At the same time, fixing the antenna conductors in clamps mounted on dielectric guy wires is possible either by installers using additional lifting vehicles, for example aerial platforms with a cradle to accommodate installers, or when placing dielectric guy wires on the ground, completely forming the antenna blade and lifting the upper ends of all guy wires to the top of the mast at the same time. Moreover, the need to create a spiral configuration of each of the four conductors of the antenna while ensuring a given step leads to confusion and requires a lot of time to untangle the conductors.

The objective of the invention is to reduce the complexity of installing the antenna. The task is achieved by the fact that in the spiral antenna the support mast is made telescopic, a mounting unit is introduced between the metal body and the support mast, formed by the upper, lower and middle parts rigidly connected to each other; a hole is made in the metal casing, into which the upper part of the mounting unit and a strip fixing the relative position of the casing and the mounting unit enter; the lower part of the mounting unit is movably docked with the upper link of the mast; the middle part is made in the form of upper and lower disks, the diameters of which are selected larger than the diameters of the upper and lower parts; four holes are made in the lower disk so that the angle between any adjacent holes is 90 degrees, each of the holes includes a snap hook snap hook secured to the upper end of each dielectric guy, and a tension device is installed mechanically connected to the other end of each guy with guy anchor; Four counterweights are placed near the anchors on the soil surface, each of which is formed by a group of wires galvanically connected to each other, and each of the resistive loads is connected between the counterweight and the lower end of the antenna conductor.

An additional reduction in the time for deployment of the antenna is achieved when the color marking is fully or partially applied to the surface of each of the antenna conductors, clips, the metal body and the middle part of the mounting unit, and the colors and marking pattern for each of the four conductors are different from each other, and the color of the marking of the clamps, the metal case and the middle part of the mounting unit corresponds to the color of the marking of the fixed conductor.

Achievable technical result is to reduce the time for deployment of the antenna.

The design of the device is shown in Fig.1-4. Figure 1 presents a General view of a spiral antenna, figure 2 is a drawing of the mounting unit, figure 3 is an assembly drawing with an installed mounting unit, figure 4 - connection of the resistive load to the counterweight.

Figure 1 presents a General view of a spiral antenna. The antenna contains four isolated from each other antenna conductor 1, four resistive loads 2, a support mast 3 with guy wires 4 and mast anchors 5; a metal case 6, inside of which there is an antenna power unit with high-frequency connectors for connecting feeders and antenna inputs, to which the upper ends of the antenna conductors 1 are connected, four dielectric guy wires 7 with latches 8 installed on them for fixing the antenna conductors, guy wires 7 form a pyramidal structure, the top of which is located near the top of the mast, and the base is near the surface of the soil on which the mast is mounted, on the guy anchors 9, these conductors are wound on a pyramid structure with a certain step.

Figure 2 shows the design of the mounting node 10. The node consists of rigidly connected to each other upper 11, lower 12 and middle 13 parts. The middle part is made in the form of the upper 14 and lower 15 disks, the diameters of which are selected larger than the diameters of the upper 11 and lower 12 parts, four holes 16 are made in the lower disk 15 so that the angle between any adjacent holes is 90 degrees.

Figure 3 presents the Assembly drawing with the mounted Assembly. A hole is made in the metal case 6, into which the upper part of the mounting unit 11 and the strap 12, fixing the relative position of the body 11 and the mounting unit, enter;

the lower part of the mounting unit 12 is movably docked with the upper link of the mast 3; in each of the holes 16 there is a hook of the snap hook 17 fixed on the upper end of each of the dielectric guy wires 7, and at the other end of each guy there is a tension device 18, mechanically connected with the guy anchor 9; Four counterweights 19 are placed near the anchors 9 on the soil surface, each of which is formed by a group of wires galvanically connected to each other, and each of the resistive loads 2 is connected between the counterweight and the lower end of the antenna 1 conductor.

The essence of the invention lies in the fact that the supporting mast is made telescopic, a mounting unit is introduced between the metal body and the supporting mast, formed by the upper, lower and middle parts rigidly connected to each other; a hole is made in the metal casing, into which the upper part of the mounting unit and a strip fixing the relative position of the casing and the mounting unit enter; the lower part of the mounting unit is movably docked with the upper link of the mast; the middle part is made in the form of upper and lower disks, the diameters of which are chosen larger than the diameters of the upper and lower parts, four holes are made in the lower disk so that the angle between any adjacent holes is 90 degrees, a snap hook snap hook is included in each hole, fixed at the upper end of each of the dielectric guy wires, and at the other end of each of the guy wires installed tensioning device, mechanically associated with the anchor guy wires; Four counterweights are placed near the anchors on the soil surface, each of which is formed by a group of wires galvanically connected to each other, and each of the resistive loads is connected between the counterweight and the lower end of the antenna conductor.

Additional advantages are provided in the case when in a spiral antenna on the surface of each of the antenna conductors, clips, the metal body and the middle part of the mounting unit, color marking is fully or partially applied, and the colors and marking pattern for each of the four conductors are different from each other, and the color of the marking of the clamps, the metal case and the middle part of the mounting unit corresponds to the color of the marking of the fixed conductor.

The device operates as follows. The deployment of a wide-range helical antenna with a telescopic mast is carried out in the following sequence. They are placed on the platform for installing the antenna of the mast anchor 5 and the anchor for dielectric guy wires 9.

Mount the telescopic mast 3 in a vertical position. The mast guy wires are hooked to the ears of the first tier of the mast telescopic, and the other ends to the anchor chains 5. By adjusting the position of the telescopic mast vertically, stretch guy wires 4. At the same time, the telescopic mast 3 takes a strictly vertical position.

On top of the telescopic mast 3 install the lower part of the mounting unit 12. The upper part of the mounting node 11 is inserted into the hole of the metal housing 6 and fixed with a strap 12.

Connect high-frequency cables 19 to the connectors mounted on the housing, and through the guy wires 16 fasten them to the mounting site. Hooks are fastened to the ears of the second and subsequent tiers of the telescopic mast 3 and laid out in the direction of the mast anchors 5.

In accordance with the color coding of the carabiners of the dielectric guy wires 7, the hook of each carabiner is inserted into the hole 16 of the lower disk 15 on the middle part of the mounting unit 13. The free ends of the dielectric guy wires are laid out in the direction of the tie rod anchors 7.

The antenna conductor 1 is unwound to a length of not more than 4 meters and hooked, observing the color coding, to the antenna input of the metal housing 6. Next, the antenna wire is subsequently hooked onto the clips 8 of the corresponding color located on the guy wires 7, while moving from the guy to the guy on clockwise. Reaching the guy line, the antenna conductor 1 hooks onto the first free lock 8 from above, the color of which corresponds to the color of the antenna conductor. During the deployment of the antenna conductor, it must always pass over all already installed and hooked guy wires, antenna conductors, as well as high-frequency cables. In this way, the antenna conductor is completely unwound. Similarly, the remaining three conductors of antenna 1 are deployed.

Extend all sections of the telescopic mast 3. After extending all sections of the telescopic mast and guy 4, they hook onto the mast anchor chains. By adjusting the position of the telescopic mast vertically, pull the braces finally with lanyards. The telescopic mast should take a strictly vertical position, while the tension of all guy wires should be the same.

The free ends of the dielectric guy wires 7 are hooked to the tie rod anchor 9. Having selected the opposite guy wires 4 in pairs, they are evenly tensioned using the tension devices 18. After the tension is carried out, the “antenna sheet” takes the form of a rectangular pyramid.

The lower ends of the conductors of the antenna 1 are connected to resistive loads 2. Lay out four counterweights 19 in the form of a fan in the direction from the installation site of the telescopic mast 3 and connect the second ends of the resistive loads to them.

When using an additional mounting unit as a supporting telescopic mast and introducing an additional mounting unit into the known structure, all work is performed at a height not exceeding the height of the first link of the telescopic mast without using bolted joints; operational fastening of dielectric guy wires on the top of the mast is carried out using carbines mounted on them; placement of the metal body on the top of the mast is also performed at a height corresponding to the height of the first link of the antenna mast; the antenna conductors are fixed in the clamps during the extension of the mast links when the installers are placed directly on the ground; the pyramidal structure is maintained in the process of extension; and there is no confusion when creating a spiral configuration due to the clear color marking of the antenna wires and devices involved in creating the antenna structure.

Thus, the proposed spiral antenna allows you to perform operations for its deployment in a shorter period of time than known devices.
