Description

The proposed utility model relates to signaling barriers containing electrified and (or) signaling (capacitive) elements that carry out a non-lethal effect on intruders and (or) detect the fact of an attempt to overcome, in particular, to the design of dielectric elements (insulators) to which electrically conductive elements are attached.

From RF patent No. 189752, a beam insulator of an electrified barrier is known, characterized in that it is equipped with several levels of attachment points for electrified wire-type elements, each of which contains at least one tensioner, fixed by a collapsible connection on a beam insulator, made of a metal strip folded in half with the formation in the area of the bend of an oval cavity, at the end of which there is a hole for passing the electrified element of the wire type, and in the middle part, across the electrified element, there is a shaft with a ratchet mechanism that provides unidirectional rotation for tension; the ends of the metal strip are connected together to form a platform for fastening.

The common essential features of the known technical solution are the following - the beam insulator of the electrified barrier is equipped with several levels of attachment points with electrified wire-type elements, each attachment point includes a tensioner fixed by a collapsible connection on the beam insulator and equipped with a ratchet mechanism that provides unidirectional rotation for tension.

The use of this design in the form of a beam insulator, fixed on the fence, allows you to mount the electrically conductive fence on the base, fixing the entire beam insulator, and also due to the presence of tensioners with a ratchet mechanism, eliminate the sagging of the electrically conductive elements fixed on the beam insulator. However, the installation of this barrier (each level of the electrified wire type element) requires a significant installation time (including re-installation at a new location), associated with the need to cut the electrified wire element of the required length, its tension, fastening, etc.

The technical problem to be solved by the proposed solution is to accelerate the installation of levels of electrified wire-type elements.

To solve this technical problem in a beam insulator of an electrified barrier, equipped with several levels of attachment points with electrified wire-type elements, where each attachment point includes a tensioner fixed by a collapsible connection on the beam insulator and equipped with a ratchet mechanism that provides unidirectional rotation for tension, in contrast from the prototype, the tensioner is made in the form of a coil with a manual drive with a switchable ratchet mechanism (gear mechanism of intermittent movement), and the electrified wire-type element is made in the form of a cable (usually galvanized steel).

Additionally, to minimize leakage currents, incl. during precipitation, the tensioners are fixed on the beam insulator through additional insulators (for example, made according to the type of pin insulators of electrical networks).

Also, in addition, to prevent sagging of the cables, as well as their excessive tension (for example, when the ambient temperature drops), the free ends of the electrified elements (unwound from the coil) are equipped with linear elongation compensation mechanisms (springs).

Thanks to the proposed solution, the following technical result is achieved - due to the use of a tensioner in the form of a coil with a manual drive with a switchable ratchet mechanism, beam insulators can be delivered to the site with installed electrified elements, for which it is enough to unroll the required length (even several levels are possible at the same time). Also, after using the barrier, the electrified elements can be rewound on reels and unwound in another place quickly and with a different working length. This is achieved incl. due to the use of a cable that eliminates the effect of twisting, it has greater flexibility and elasticity. In addition, through the use of additional insulators, leakage currents are minimized, and due to the mechanisms for compensating for linear elongation (springs), sagging of the cables is prevented, as well as their excessive tension (manual tension or loosening can be performed by twisting or loosening the coil).

The proposed technical solution can be used in the construction of electrically conductive barriers with beam-type insulators and electrically conductive wire elements. This solution can be used both for electrified type barriers, where the elements are always energized or connected in the presence of a violation signal, and for capacitive type alarm barriers. Its use is especially relevant for mobile and rapidly deployable obstacles, incl. reusable.

The solution is illustrated in Fig. 1-5, which show respectively:

- fig. 1 - general view of the linear part of the electrified barrier;

- fig. 2 - beam insulator, fixed on the support (stand) of the barrier;

- fig. 3 - view of the reel-tensioner from the side of the ratchet switch;

- fig. 4 - view of the tensioner coil from the side (from the side of the winding-winding of the cable of the electrified element);

- fig. 5 is a view of the tensioner reel from the side of the handles for its rotation.

The figures indicate:

1 - end post;

2 - device for fixing the free end of the electrified element - cable;

3 - electrified element - cable;

4 - clip for movable fastening of the cable;

5 - intermediate stand;

6 - rack of a beam insulator with attachment points for electrified elements - cables;

7 - reel-tensioner - winding device of the electrified element - cable;

8 - bracket for attaching the beam insulator post to the barrier support;

9 - handles for rotating the coil;

10 - fastening carabiner;

11 - linear elongation compensation mechanism - extension spring;

12 - switch of the ratchet (ratchet) mechanism;

13 - additional insulator;

14 - support (rack) of the barrier.

Shown in FIG. 1-5, the electrified barrier contains supports 14 fixed on them with the help of brackets 8 of the rack 1, 5, 6 of beam insulators (for example, made of dielectric fiberglass). Fixing devices 2 are fixed on the terminal posts 1. Clips 4 are installed on the intermediate posts 5 to support the electrified element - cable 3, ensuring its spatial arrangement while maintaining horizontal mobility. Coils 7 with a ratchet mechanism and handles 9 are installed on the racks 6 through additional insulators 13. At the same time, one end of the cable 3 is fixed to the coil 7 motionless. And the other free end of the wound cable 3 is equipped with a spring 11 and a carabiner 10. Coils 7 can be manufactured depending on the parameters of the fence (length of spans, cable thickness, etc.), but known mass-produced inertial fishing reels can also be used, which have all the necessary parameters and details.

Installation of an electrified barrier is carried out as follows:

- to the place of installation (deployment), the electrified barrier is delivered in the form of assembled beam insulators - coils 7 with a cable 3 wound on them (up to 100 m, depending on the maximum length of the barrier with a small margin), free the ends of which are equipped with a spring 11 and a carabiner 10. The delivery set also includes brackets 8 and stands 1 and 5 with fixing devices 2 and clips 4 installed on them;

- at the installation site, posts 1, 5, 6 are fixed to the barrier supports 14 (already existing or newly installed) by means of brackets 8;

- the switches 12 of the ratchet mechanisms are transferred to the neutral position and then, by pulling, the cables 3 are unwound, during which the cables 3 are inserted into the clips 4 of the racks 5, and then, with the help of carabiners 10, they are fixed on the fixing devices 2 of the racks 1;

- the switches 12 of the ratchet mechanisms are switched to the working position and the cables 3 are tensioned by rotating the coils 7;

- the electrified barrier is connected to the power supply in a regular way and put into operation.

During operation, a slight elongation of the cables can be self-compensated by their own elasticity and springs. With more significant deformations, you can easily wind up or unwind the cable with coils manually.

When moving (mounting in a new place) or changing the shape and (or) size of the barrier, the free ends of the cable are released, and it is wound onto coils. Further, at a new location or at a changed perimeter, the installation described above is carried out with the rewinding of the already required new length of the cable.
