FR2852432A1 - Immovable e.g. historical monument wall, and movable object e.g. bus, protecting device, has turbine driven by motor for inhaling air into tube and sending air charged with solvent to solvent detector - Google Patents

Abstract

The device has a turbine (1) driven by a motor (2) for inhaling air into a tube (3) and sending the air charged with solvent (7) to a solvent detector (4). The solvent detector provides information about the air, where the information is transmitted by all electric, optic, and electro-mechanic units closely connected to a remote station.

Description

i

  The present invention relates to a device making it possible to protect “taggers” the walls of historic monuments the walls of private dwellings to protect rolling stock such as bus, train, metro or any other material liable to be damaged by wild paint.

  Rolling stock is often stopped during its hours of non-operation on garage tracks located kilometers from stations and it is often difficult to monitor them; similarly, the walls of buildings are liable to be degraded by wild paint; these degradations cost tens of millions each year.

  The device according to the invention allows monitoring and protection of an infinite number of points simultaneously, which it would be impossible to carry out with a security team or a video system. According to a first characteristic, it in fact comprises an air suction system to be monitored and a system for analyzing the chemical components and the solvents contained in the paint aerosols; these aerosols being used to make these graffiti. This chemical component analysis system is housed in the body of the suction system, is connected to an electronic measurement system; so when the detection of a solvent and validated the system sends an alarm which can trigger a camera, a camera system, or any other system allowing to identify the "taggers"; or alert a group of guards in order to put in escape or take the "taggers" in flagrant elite.This Alarm can be transmitted by high frequency, by optical fiber or any other information transmission system.

  The accompanying drawings illustrate the invention: Figure 1 shows in section, the device of the invention.

  FIG. 2 represents in section, a description of the possible installation of this device in a wall or a wall.

  With reference to these drawings, the device comprises A turbine (1) driven by a motor (2) sucks the air to be analyzed and sends this air to the solvent detector (4) the air is guided in the tube (3) , the system is housed in the tube (3) in order to have a quick response time.

  For operation, the air is sucked in by the turbine then led into the tube and conveyed to the detector. This air is expelled at the other end of the tube.

  In the embodiment according to FIG. 2, the system is integrated into the wall (8) or wall (8) to be protected, the aerosol (6) propels paint and solvents (7). These solvents (7) are guided by the guide (5) then aspirated by the turbine (1) then directed towards the detector (4) through the tube (3). In the case of rolling stock to extend the life of the detector, the valve (9) can shut off the air supply.

  The valve (9) can be closed for vehicle or building maintenance operations.

Claims (1)

  1) Device intended to protect real estate and transport equipment from taggers and wild paints by detection of the solvents contained in the aerosols of painted paint, characterized in that it comprises a turbine (1) sucking air into a tube (3) bringing the air charged with solvent (7) to a detector (4), the information given by the detector can be transmitted by all electrical electromechanical optical means in order to be used by a distant or non-distant station.
