    SAFETY SCREEN AGAINST ARCBOWS AND / OR FLAME REPORTS
    TECHNICAL FIELD OF THE INVENTION
    The present invention describes a safety screen comprising a visor and one or more legs, which can preferably be placed over a conductive cable or sleeve and has the property of neutralizing arcs and / or flashover. The safety screen allows work to be carried out safely on a conductive cable or sleeve.
    BACKGROUND OF THE INVENTION
    Work on electricity cables, electricity sleeves, ... pose enormous risks. Incorrect handling can lead to electrocution, serious injuries and even death. Arcs can arise in such operations, which originate in a powerful discharge between two or more conductors. Due to this discharge, the current will choose a random path, where a plasma arc can be formed and large amounts of energy can be released. The result is a powerful blowtorch (flashover), which can burn and / or kill the skilled person.
    The skilled person can protect against such arcs and / or flashover by means of specially developed clothing, i.e. a protective suit, thick gloves and a helmet.
    For example, US3458864 describes a headgear with veil, in which the veil covers a sufficiently large area of the upper body and thus protects the user against blow flames, etc.
    US3427660, US2638592 and US20110030114 similarly describe headgear with visor and / or veil according to different embodiments.
    However, such helmets are often poorly breathable, heavy and can quickly sweat the user on hot days. As a result, those skilled in the art are more likely to strip off their homesickness, the face shield is lost and the risk of burns and / or injury increases again.
    The present invention therefore describes a safety screen, comprising a visor and one or more legs, which can preferably be placed over a conductive cable or sleeve and has the property of neutralizing arcs and / or flashover. The safety screen allows work to be carried out on a conductive cable or sleeve in a safe manner, and ensures that the skilled person can move freely and unrestrained around the conductive cable or sleeve and does not have to wear a helmet.

    Some Arc Flash Protection Systems have already been described:
    - US6020560, which describes an enclosure to protect high voltage cables from flashover from contact with a grounded object or other conductor. The sheath consists of a flexible panel, the ends of which can be clicked together and the inside of which contains an additional sheath that firmly encloses the high-voltage cable.
    US2010218988 which describes an envelope consisting of 2 dees which can be oriented at a specified angle relative to each other and which encase a high voltage wire which is held by gripping elements.
    However, the above references do not have the same functionality as the invention described below.
    SUMMARY OF THE INVENTION
    The present invention describes a safety screen, comprising a visor and one or more legs, which can be placed over an object, preferably a conductive cable or sleeve, and has the property of neutralizing arcs and / or flashover.
    In a specific embodiment, the visor of the safety shield is curved with a convex exterior and a concave interior.
    In a specific embodiment, the inside of the visor is placed over the object in question.

    DETAILED DESCRIPTION OF THE INVENTION
    The present invention describes a safety screen (1), comprising a visor (2) and one or more legs (3), which can be placed over an object (5), preferably a conductive cable or sleeve, and has the property of arcing and / or neutralize flashover.
    In a specific embodiment and as schematically shown in Figures 1 and 2,
    - 4 BE2®Œ2ÆW6440, the visor (2) of the safety shield (1) is curved with a convex exterior and a concave interior, the concave interior of the visor being placed over the object in question. This conformation with concave interior ensures that arcs and / or flashover are collected by the screen and directed away from the skilled person, thus optimally protecting the skilled person.
    The dimensions of the safety screen (1) will be adapted to the size of the object over which it is placed and must at least include the necessary free work space for the skilled person. In a preferred application, the safety screen according to the invention is placed over a sleeve connection on the electricity network, and more particularly over sleeve connections on both transmission (high voltage) and distribution networks (medium voltage and low voltage distribution networks). Such sleeve joints are typically 40 cm long. In such an application, the safety shield (1) will be at least 50 cm long and 40 cm wide. Since the legal working space for such an application is set at at least 1m 3 , this ensures that the skilled person still has sufficient space when the screen is placed on an electrical socket.
    In certain embodiments, the visor (2) is made of plastic, preferably polycarbonate, which has the property of being non-conductive and thus prevents the arc from further advancing through the visor to the outside of the screen. In addition, the visor (2) is transparent, which allows the person skilled in the art to keep an overview during his actions on the object concerned (5), such as a conductive cable or sleeve. The visor (2) is preferably adjustable in height, so that the safety screen can be placed over the object (5) while retaining sufficient working space for the user without compromising the safe shielding of the object to be processed, in particular a conductive cable or sleeve. The flexibility in use can possibly be further increased by ensuring that the visor (2) is rotatable and / or tiltable relative to the object in question (5). Thus, in one embodiment of the invention, the safety shield (1) is further characterized in that it is height adjustable. In another embodiment of the invention, the safety shield (1) is further characterized in that the visor (2) is rotatable and / or tiltable relative to the respective object (5). In a preferred form of the present invention, the safety screen (1) is further characterized in the fact
    - 5 BE2®Œ2ÆW6440 that it is height adjustable, and that the visor (2) is rotatable and / or tiltable relative to the object concerned (5). All this ensures that the professional is not inhibited in his movements, can coordinate his actions better and the screen is not unnecessarily in the way. The current embodiments also allow to operate on the air network.
    If the visor (2) is worn (i.e. presence of cracks, tears, ...), it is possible to replace the visor.
    The one or more legs (3) are preferably located on the inside of the visor (2). Again ensuring that the clear working space is safeguarded under the safety screen, the one or more legs (3), preferably two or four, are arranged on the periphery, of the visor (2), more in particular peripherally and on the inside (concave side) of the visor. In the specific embodiment as shown in Figures 1 and 2, the visor (2) has a more or less rectangular curved shape and the legs (3) are located on the short sides of the visor.
    As already indicated above, the safety screen (1) is preferably adjustable in height. It will be clear to the skilled person that this functionality can be achieved in various ways, such as a height-adjustable frame on which the visor (2) is fixed, or a height-adjustable post (s) (3) and each of these known variants are within the scope of the present invention. Likewise, the rotatable and / or tiltable mounting of the visor (2) can also be realized in different ways, and each of these solutions known to the skilled worker are within the scope of the present invention. In a specific embodiment, both previous features are integrated in the leg or legs (3) of the safety screen (1). Integration of the height adjustability and rotatability in the legs (3) saves time, which only benefits the already limited working space. Thus, in an embodiment according to the invention, the safety screen (1) is characterized in that the one or more legs (3) are adjustable in height, preferably extendable. In a further embodiment, the safety screen (1) is characterized in that the one or more legs (3) are hingedly connected to the visor (2), so that the visor is rotatable and / or tiltable opposite the one or more legs . In a specific embodiment of the present invention, the safety screen (1) is characterized in that the one or more legs (3)
    - 6 BE2®Œ2ÆW6440 are extendable and are hingedly connected to the visor (2).
    The safety screen (1) is placed over an object (5) in order to protect the manipulator against the dangers of working on the object such as solid particles or chips such as dust and splinters when working on the object; liquid splashes, for example when working with dangerous liquids; infrared or UV radiation; flames, such as arcs and / or flashover when working on a sleeve connection to the electricity network, and more particularly over sleeve connections on both transmission (high voltage) and distribution networks (medium voltage and low voltage distribution networks).
    The energy associated with such hazards may be high, such as with an arc or flashover, that the safety shield is best anchored to prevent the shield from being knocked out when such a hazard occurs. Thus, in a further embodiment of the present invention, the safety screen (1) is provided with one or more anchoring elements (4), such as clamps, pins, and the like. In a specific embodiment, the one or more legs (3) are provided with anchoring elements (4).
    For application to a sleeve connection to the mains, and more particularly to sleeve connections on both transmission (high voltage) and distribution networks (medium voltage and low voltage distribution networks), the anchoring elements (4) will preferably consist of clamps which electricity cable can be secured; more particularly clamps on the free ends of the one or more legs. By clamping the cable on either side of the sleeve, according to an embodiment of the present invention, such safety screens prevent the cable from swinging uncontrollably when an arc or flashover occurs, thereby increasing safety for the user.
    In certain embodiments, the one or more legs (3) are extendable, so that the safety shield (1) can optimally cover each cable or sleeve, and / or have clamps (4) for fastening the safety shield to the object (5) concerned and it can be guaranteed at all times that the screen will stay securely in place and not fall over. In addition, these legs provide additional grounding. In the embodiment as shown in Figure 1, the clamps (4) are also rotatable opposite the power cable and provide or contribute to the rotatable and / or
    - 7 BE2®Œ2ÆW6440 can be tilted from the safety screen (1) opposite the object (5) (sleeve) over which it is placed. In a further embodiment, the one or more legs (3) are made of high impact polyamide.
    Furthermore, a method of working safely on an object (5), preferably on a conductive cable or sleeve, is described by using a safety shield (1) as described above and below.
