RU59677U1 - VIBRATION DETECTION DEVICE "DELPHIN-M" - Google Patents

Abstract

The utility model relates to the components of technical vibrational means of guarding the perimeters of objects equipped with a mesh, trellis, concrete or brick fence and is used as part of a detection tool to record the direct impact of a detection object on a fence. The vibration detection means "Dolphin-M" contains a mesh alarm fence, a cable sensitive element and a system (unit) for collecting and processing information. Mesh alarm fence is a single-row mesh fence on metal racks installed in the ground at a distance of 3-4 meters from each other, with a cable sensing element mounted on a mesh cloth. The mesh security fence has a height of 2.3 meters from ground level, and is deployed with a length of up to 250 meters. To ensure anti-tamper properties, the reticulum of the detection means is 300 mm deep in the ground. In the embodiment of a full-profile direct signaling fence, each carrier rack consists of three parts, fastened to each other and having a different degree of rigidity. Bearing racks installed along the edges of the signal fence are equipped with cable extensions, adjustable in length.

To exclude the possibility of landing on the signal boom of large birds at the mesh of the detection tool, the longitudinal thread is cut off and vertical pins 50 mm high are formed from the transverse threads of the mesh fabric.

Description

The proposed utility model relates to the constituent parts of the protection of the perimeters of objects and can be used as a means of detecting attempts to unauthorized to overcome the protected boundary of the perimeter of the object.

Vibration detection tool "DELPHIN-M" provides processing according to a certain algorithm of signals coming from sensitive elements when exposed to an alarm obstacle in the process of its overcoming by an intruder, generating an output response signal and issuing it to an information collection and processing system (SSOI) or to a reception control equipment.

According to the mode of application (functioning), the vibration detection means "DELFIN-M" refers to equipment for continuous long-term use without daily maintenance.

Known designs of vibration detection means with an extended boundary of protection, consisting of load-bearing racks, mesh web and cable sensing element. A common drawback of the constructions of the known detection means is the high rigidity of the load-bearing posts, determined by their constant cross-section in height, which allows the detection object to overcome the obstacle using improvised means, for example, a ladder, without registering the impact on the barrier.

The purpose of the utility model is to create a design of vibration detection means, which would eliminate the above drawback.

The technical result from the use of the utility model is the creation of the design of the support strut of the vibration detection means, having variable stiffness in height, stepwise decreasing with increasing height, while maintaining all the properties of the vibration detection means.

The technical result in this case is achieved due to the fact that the design of the support rack consists of three parts having different stiffness, interconnected in the lower part - by welding, in the upper part - by bolts. The cross-sectional profile of each part of the support rack varies both in shape - from the box-shaped in the lower part, to the U-shaped in the middle and upper part, and in area that decreases with the transition from the middle part to the upper. As a result, the entire structure of the support rack receives three degrees of rigidity in height.

Vibratory detection tool "DELPHIN-M" provides blocking of one section equipped with a protective device, up to 250 m long.

Vibratory detection tool "DELFIN-M" is designed to work in various seasonal conditions in the presence of the following climatic and interference factors:

- solar radiation;

- rain with an intensity of up to 40 mm / h;

- snowfall with an intensity of up to 10 mm / h;

- wind at a gust speed of up to 30 m / s;

- snow cover up to 1 m high;

- ice with a crust thickness of up to 10 mm with a wind of up to 10 m / s;

- electromagnetic and seismomagnetic disturbances during a thunderstorm. And also from the work of industrial enterprises;

- grass cover of arbitrary height;

- melt water up to 0.3 m high;

- power lines under voltage up to 330 kV, crossing

boundary at an angle of at least 45 ° or passing along at a distance of at least 50 m;

- the presence of underground power cables under voltage up to 40 kV per

distance not closer than 1 m from the fence;

- the passage of aircraft such as YAK-42, AN-24 at a height of not less than

1000m, helicopters of various types at a height of not less than 100 m;

- overcoming barriers (through special manholes

size 150 × 150 mm) animals not larger than

100 × 100 × 500, gathering and landing on a means of barricade birds weighing

up to 3 kg (up to 10 pcs.).

Structurally, the vibration detection tool "Dolphin-M" is a single-row mesh fence on metal support posts 1, installed in the ground at a distance of 3-4 meters from each other, with a cable sensing element 7, mounted on a mesh cloth 5 and a collection system (unit) and information processing connected to the cable sensor 9.

Vibratory detection tool "DELFIN-M" has a height of 2, 3 meters from ground level and is deployed up to 250 meters long. As the mesh fabric 5, a welded, galvanized mesh of the SSCP or OTs type is used. The mesh web 5 is attached to the supporting posts 1 with washers, bolts and trims.

To ensure anti-tampering properties, the mesh web 5 of the DELFIN-M detection tool is buried in the ground 8 by 300 mm.

The support column 1 consists of a bent, perforated, U-shaped profile (56 × 33 × 3) mm, 2500 mm long, with a U-shaped profile 9 (50 × 18 × 29 mm, 1020 mm long, welded to using a bolted connection, perforation on load-bearing posts 1 allows the use of various types of nets, simplifies installation with a complex perimeter relief with a large number of height differences.

To exclude the possibility of landing on a vibrational detection tool "DELPHIN-M" large birds at the mesh fabric, a longitudinal thread is cut from above and vertical pins 6 with a height of 50 mm are formed from the transverse threads of the mesh fabric.
