Description

The utility model relates to lighting equipment, namely to radiation-resistant luminaires, and can be used to create the required illumination in radiation-shielding chambers.

A device for illuminating radiation chambers is known [RU 1238482, 02.17.1984], including a housing with a protective glass located in the penetration of the chamber wall and a light source fixed in the holder. The light source holder is equipped with rolling bearings for interacting with the inner surface of the penetration, and the housing has a device for connecting it to the light source holder, while the housing has longitudinal through grooves for the passage of the rolling bearings, and the light source holder is rigid and mounted coaxially in the housing. The device allows to reduce the risk of exposure to maintenance personnel during containerless replacement of the light source.

A disadvantage of the known device is the risk of exposure to maintenance personnel during maintenance of the device, in particular when replacing it. This drawback is due to the fact that the replacement of the device installed in the penetration of the chamber wall is done manually.

A device is known, which is a lighting system of a radiation chamber [KR 100777435, publ. November 21, 2007], comprising a housing with a sliding groove; a lamp holder detachably connected to the sliding groove and including a slider and an insulator provided on the upper surface of the slider; a lamp connected to the lamp holder. The housing is equipped with a reflective plate for reflecting the light emitted by the lamp in the forward direction, the housing further comprises a protective cover for protecting the lamp installed in it. This device allows you to perform the operation of replacing the lamp using a manipulator installed inside the radiation chamber.

A disadvantage of the known device is the difficulty of replacing the lamp, due to the large number of operations performed by the manipulator.

The technical result that can be obtained by using the inventive utility model is to reduce the time for maintenance of the lighting device in a radiation protective chamber by reducing the number of operations performed by the manipulator when installing and replacing the light source.

The indicated technical result is achieved in that the lighting device comprises a bracket, a holder, a light source fixed on the holder, connecting cables, pressure leads for connecting cables, a metal hose, a coaxial electrical connector, the male part of which is installed in the holder, and the socket part is installed in the bracket.

The bracket has the form of a vertical hollow cylinder closed at the bottom, equipped with fasteners for fastening to the wall of the radiation-shielding chamber, while the socket part of the coaxial electrical connector is installed in the lower part of the bracket.

A metal hose is attached to the bottom of the bracket for a connecting cable that provides power to the connector.

The open end of the bracket can be equipped with a guide funnel.

The holder has the form of a hollow cylinder closed at the top, at the lower end of which is located the male part of the coaxial electrical connector. The external diameter of the holder is smaller than the internal diameter of the bracket and is selected so as to ensure that the holder is installed in the bracket.

The holder contains a pressure seal for the connecting cable.

A protective cover may be welded to the holder, the diameter of which coincides with the diameter of the bracket funnel guide and located at a level at which the protective cover is tightly contacted with the upper edge of the funnel guide during fixing the holder in the bracket.

The light source may be attached to the holder using a base mounted on the upper end of the holder.

The base can be equipped with a gripping bracket.

The light source contains a pressure seal for the connecting cable.

The light source may be, for example, LED or halogen.

The bracket is used to fix the light source on the inner wall of the radiation protection chamber.

The holder serves to fix the light source in the bracket, and also protects the connecting cable and electrical connector.

The coaxial electrical connector, the plug and socket parts of which are installed in the holder and the bracket, respectively, allows electrical contact at the time of fixing the light source with the holder in the bracket.

The guide funnel located on the bracket facilitates the convenience of installing the light source with the holder in the bracket using a power manipulator.

A protective cover welded to the holder provides protection against the penetration of foreign objects, dust and moisture into the connector.

The base serves to fix the light source on the holder.

The gripping bracket, mounted on the base, serves to facilitate the capture of the light source with the holder using the manipulator.

The metal hose protects the connecting cable from ionizing radiation.

In the drawing of FIG. 1 shows a general view of a lighting device.

In the drawing of FIG. 2 shows a longitudinal section through a lighting device.

The lighting device includes: a bracket (1) with a guiding funnel (2), a holder (3) with a pressure seal (4) and a protective cover (5), a base (6) with a gripping bracket (7), a light source (8) with a pressure seal ( 9), the female part of the coaxial connector (10), the male part of the coaxial connector (11), the connecting cable (12) and (13), the metal sleeve (14).

The bracket (1) is located inside the radiation-protective chamber and is fixed on its inner wall. The connecting cable (13) is led to the socket part of the coaxial connector installed inside the bracket (1)

(10) through the metal sleeve (14). The light source (8) is fixed on the base (6). The base (6) is mounted on the holder (3). One end of the connecting cable (12) is connected to the light source (8) through a pressure seal (9). The other end of the connecting cable (12) is inserted into the internal cavity of the holder (3) through the pressure seal (4) and connected to the male part of the coaxial connector

(eleven). In the working position, the holder (3) is fixed in the bracket (1), while the male part of the coaxial connector (11) is in contact with the socket part of the coaxial connector (10), providing electrical contact. The guide funnel (2) provided on the bracket (1) is closed by a protective cover (5) welded to the holder (3).

If it is necessary to repair the lighting device, a power manipulator located in the radiation-protective chamber grabs the gripping bracket (7) located on the base (6) and removes the holder (3) with the light source (8) from the bracket (1). When the holder (3) is removed from the bracket (1), the electrical contact is disconnected at the same time and the light source (8) is disconnected from the power supply.

To connect the lighting device, the power manipulator, capturing by the gripping bracket (7), installs the holder (3) with the light source (8) in the bracket (1). At the moment of fixing the holder (3) in the bracket (1), the male part of the coaxial connector (11) is combined with the socket part (10) and the electrical contact closes, as a result of which the light source (8) is connected to the power supply.

Thus, the connection of the light source occurs directly when the holder is fixed in the bracket, and the disconnection occurs when the holder is removed from the bracket, which significantly reduces the time for replacement and maintenance of the lighting device in a radiation protective chamber.

When conducting a search on the sources of patent and scientific and technical information, no solutions were found containing the entire set of proposed features, which allows us to conclude that the claimed utility model meets the criterion of "novelty."

The inventive utility model meets the condition of patentability "industrial applicability", since its implementation is possible using existing equipment and using well-known technologies.
