Abstract

An alarm fence, which is an integral part of the means of detecting the vibration principle of action, containing load-bearing racks, a mesh web and a cable sensing element, is designed to build extended, closed lines of guard for perimeters of objects. This fence is distinguished by the fact that it is equipped with straight peaks that are equipped with a flat safety barrier made of reinforced barbed tape, or L-shaped peaks that are equipped with a mesh or flat safety barrier made of reinforced barbed tape, or Y-shaped peaks that are equipped with a spiral safety barrier from reinforced barbed tape. The tops of the fence, equipped with a mesh or safety barriers made of reinforced barbed tape, create an additional obstacle and significantly complicate the overcoming of the signaling barrier by climbing over it.

Description

The proposed utility model relates to the constituent parts of the technical means of guarding the perimeters of the objects - signaling barriers, and can be used as a physical obstacle to protect against unauthorized entry into the territory of the guarded object and work as a part of a detection tool for recording the direct impact of the detection object on the fence.

Known design signaling barriers, consisting of load-bearing racks, mesh cloth and cable sensing element.

Signs of analogues that match the features of the proposed utility model:

1. The presence in the composition of the fence load-bearing racks, mesh cloth and cable sensing element.

2. The cable sensing element is mounted on a mesh cloth.

The disadvantage of these devices is the absence of barrage elements that impede the overcoming of the barrage by climbing over it.

As a prototype of the selected "Mesh signaling fence" (Patent No. 2266382, 03/26/2004), which contains load-bearing racks, mesh cloth and cable sensing element.

Structurally, the mesh signal fence is a single-row mesh fence on metal load-bearing posts installed in the ground at a distance of (3 ÷ 4) meters from each other, with a cable sensing element mounted on the mesh web. The fence has a height of 2.3 meters, from ground level. As mesh

cloths are used welded, galvanized mesh type SSCP or OC. The mesh web is attached to the supporting posts using washers, bolts and trims. To ensure anti-tar properties, the mesh web of the fence is buried in the ground by 300 mm.

The support column consists of a bent, perforated, U-shaped profile (56 × 33 × 3) mm, 2500 mm long, with a U-shaped profile (50 × 18 × 2) mm welded in the lower part, 1250 mm long, forming a box section , and vertices from a bent, perforated U-shaped profile (30 × 20 × 2) mm, 1020 mm long, fixed with a bolted connection. Perforation on load-bearing racks allows the use of various types of nets, simplifies installation with a complex perimeter relief with a large number of height differences. To ensure the necessary tension of the mesh web, the support racks installed along the edges of the linear sections of the signal fence are equipped with braces in the form of steel cables, with their length adjustment using lanyards. At the turning points of the route, two load-bearing racks are installed in one well at a distance from each other so that the angle formed by these racks when tensioning the mesh webs in each direction of the route does not create obstacles for the mesh webs to vibrate in the vertical plane when the object is exposed detection on the security fence.

To exclude the possibility of landing on the signal boom of large birds at the mesh web, a longitudinal thread is cut from above and vertical pins 50 mm high are formed from the transverse threads of the mesh cloth.

Signs of an analogue that match the features of the proposed utility model:

1. The presence in the composition of the fence load-bearing racks, mesh cloth and cable sensing element.

2. The cable sensing element is mounted on a mesh cloth.

3. Bearing racks consist of a bent, perforated, U-shaped profile and are made of parts having different stiffness due to a change in the cross section of the profile of each part over an area that decreases when moving from the lower to the upper.

4. The lower part of the mesh web is buried in the ground.

5. Bearing racks installed along the edges of the linear sections of the signal fence are equipped with braces in the form of cables, which are adjustable in length using lanyards.

6. At the turning points of the route, two load-bearing racks are installed in one well at a distance from each other so that the angle formed by these racks, when tensioning the mesh webs in each of the directions of the track, does not create obstacles for the vibrations of the mesh webs in the vertical plane.

The disadvantages of this prototype device include:

1. The low height of the fence (2.3 meters), which in winter conditions with an average snow depth of 0.8 meters creates conditions that facilitate overcoming the obstacle by climbing.

2. The absence of barrage elements that impede the overcoming of the fence by the method of climbing through it.

The objective of the utility model is to create an alarm fence in which the above disadvantages would be eliminated.

The technical result obtained by the implementation of the utility model:

- increase the barrage properties of the signal barrage.

The problem is solved due to the fact that in the signal boom containing the supporting racks, mesh cloth and cable sensing element, the following difference is provided - the boom is equipped with straight peaks that are equipped with a flat safety barrier made of reinforced barbed tape, or L-shaped peaks that are equipped with a mesh or flat safety barrier

reinforced barbed tape, or Y-shaped peaks that are equipped with a spiral safety barrier made of reinforced barbed tape.

Between the set of essential features of the claimed object and the achieved technical result there is a causal relationship, namely:

1. Due to the installation of peaks above the mesh fence equipped with a mesh or a flat safety barrier or a spiral safety barrier made of reinforced barbed tape, the overall height of the fence is increased, which makes it difficult to overcome the obstacle by climbing.

2. L-shaped peaks equipped with a mesh, due to the inclination of the mesh, create an additional obstacle when overcoming the obstacles by the climb method.

3. Due to the significant cutting effect and springing properties, a flat security barrier made of reinforced barbed tape on vertical and L-shaped vertices represents an insurmountable physical obstacle, and a spiral security barrier made of reinforced barbed tape on Y-shaped vertices is a particularly difficult physical obstruction, due to its volumetric designs.

The utility model can significantly complicate the overcoming of the signal barrage by the method of climbing through it.

The above structural elements are made as follows:

1. Structurally, the signal fence is a single-row mesh fence on metal load-bearing racks installed in the ground 11 at a distance of (3 ÷ 4) meters from each other. Bearing racks installed at the edges of straight sections of the fence and at the points of turn of the route, as well as every fifth - tenth rack of a straight section of the fence, depending on the density

soil, fixed in soil 11 using concrete 5. Next to these uprights are fixed using concrete 5 hooks 4 for attaching cable braces with turnbuckles 1. At the turning points of the track, two load-bearing posts are installed in one well at a distance from each other in such a way so that the angle formed by these struts, when pulling the mesh blades 10 and the safety barriers 7 and 14 in each of the directions of the route, does not create obstacles for the oscillations of the barrier in the vertical plane when the detection object acts on the alarm th barrier. The signal fence is 3.3 meters high, from ground level, and unfolds up to 250 meters in length, forming one signal area. The growth of the fence is provided by connecting the signaling sections in series with each other to organize an extended closed line of guard of the perimeter of the object.

2. Bearing racks contain upper beams 2 and lower beams 3 of perforated, U-shaped profile, which are interconnected by bolts. Beams 2 and 3 have different stiffness due to changes in the cross-sectional profile of the beams by area. Perforation on beams 2 and 3 allows the use of various types of grids, simplifies installation in difficult terrain with a large number of vertical differences.

To ensure the necessary tension of the mesh web 10 and the safety barriers 7 and 14, the support racks installed along the edges of the linear sections of the alarm fence are equipped with braces in the form of steel cables, with their length adjustment using lanyards 1.

3. To increase the barrage properties of the signal boom, the support racks are additionally equipped with:

- in the first embodiment, with straight peaks 9 equipped with a flat safety barrier made of reinforced barbed tape 7;

- in the second embodiment - L-shaped peaks 12, equipped with a mesh cloth 10;

- in the third embodiment - L-shaped peaks 12, equipped with a flat safety barrier of reinforced barbed tape 7;

- in the fourth embodiment - Y-shaped peaks 13, equipped with a spiral security barrier of reinforced barbed tape 14.

To fasten the safety barriers from reinforced barbed tape 7 and 14 at the peaks 9, 12 and 13, two rows of steel, galvanized wire 6 with a diameter of 3 mm are fixed, which holds the safety barriers in a horizontal position in the spaces between the tops of the load-bearing racks of the fence.

Safety barriers made of reinforced barbed tape 7 and 14 are attached to wire 6 with inter-turn pitch using pieces of steel, galvanized wire with a diameter of 1 mm.

4. As the mesh fabric 10, a welded, galvanized mesh of the SSCP type is used. The mesh web 10 is attached to the supporting racks and L-shaped tops 12 using bolts, washers and straps. To ensure anti-undermining properties, the mesh web 10 of the signal fence is buried in the ground 11 by 300 mm.

5. Cable sensing elements 8 are placed along the fence: one in the upper part of the mesh cloth 10 or a safety barrier made of reinforced barbed tape 7, 14, the other in the lower part of the mesh cloth 10 at a distance of (800 ÷ 1000) mm from the ground level. Fastening of cable sensitive elements 8 to the mesh web 10 is carried out with a pitch of 600 mm, using light-resistant plastic ties. Fastening of cable sensitive elements 8 to safety barriers from reinforced barbed tape 7, 14 is carried out with inter-turn step, using pieces of steel, galvanized wire with a diameter of 1 mm.

The applicant developed sets of design documentation GKAZH.425719.044, GKAZH.425719.045, GKAZH.425719.047, GKAZH.425719.048, made prototypes of the proposed options for signaling barriers and tested them.
