Description

A hot-cell lighting device

The present invention relates to a hot cell lighting device, and more particularly, to a hot cell lighting device that facilitates replacement of a frame module in which a lamp and a lamp are installed, and enables a stable replacement of the lamp.

Nuclear fuel and irradiated specimens irradiated with radiation have strong radioactivity, so they are treated in an enclosed space called a hot cell which is shielded from radioactivity to avoid radiation exposure of the tester.

The hot cell is a shielding facility which can be operated by a remote control device while making a room with a transparent lead glass. In order to handle and test the irradiated fuel and irradiated specimen, the illumination device in the hot cell should always be operated normally.

However, since the lamp of the lighting apparatus is not used permanently, it is necessary to replace it with a new bulb after a certain usage time, that is, when the life time of the bulb is exhausted, or to repair the lighting apparatus if the lighting apparatus fails .

At this time, in a nuclear facility that can not be accessed by a person, that is, a hot cell, a crane or a manipulator is used to replace the lamp or to maintain the lighting device.

Hereinafter, a lighting apparatus of a conventional hot cell will be briefly described with reference to FIG.

1, the hot cell illumination device comprises a housing 10 having a slide groove 11, a lamp holder 20, and a lamp 30.

The housing 10 constitutes an appearance of the hot cell illumination device and forms an entire frame so that the respective components can be installed.

At this time, the support ring 12 for fixing the illumination device in the hot cell is installed at the upper end of the housing 10. [

The lamp holder 20 is coupled to and disconnected from the housing 10 while moving in and out of the slide groove 11 of the housing 10 and a socket 21 is provided at one side thereof to which the lamp can be detached.

At this time, a thread is formed on the inner peripheral surface of the socket 21.

The lamp 30 emits light through power supply to illuminate the inside of the hot cell.

At the lower end of the ramp 30, a thread is formed for screw connection with the socket 21. [

The hot cell illumination device having the above structure is characterized in that the lamp 30 is screwed to the socket 21 of the lamp holder 20 and the lamp holder 20 to which the lamp 30 is coupled is inserted into the slide of the housing 10 The lamp installation in the housing 10 is completed by being coupled to the groove 11.

Meanwhile, in order to replace the lamp of the hot cell illumination device having the above-described configuration, a gripper serving as a jaw of the remote controller is operated by using the remote controller described above.

The gripper separates the power cable 22 connected to the lamp holder 20.

Thereafter, the gripper opens the door D of the housing 10, draws the lamp holder 20 coupled with the lamp 30 from the slide groove 11, Dispose of it at the disposal site.

Thereafter, the gripper draws the lamp holder 20 with the new lamp into the slide groove 11 in the housing 10, connects the power cable 22, and then closes the door D, The replacement operation is completed

However, the hot cell illumination device according to the related art has the following problems.

First, there is a problem that economical efficiency due to the replacement of the lamp is deteriorated as the lamp holder 20 in which the lamp 30 is installed is completely disposed to replace the lamp 30.

That is, not only the cost of producing a new lamp holder but also the cost of processing the radioactive waste has increased, which is not economical to replace the lamp.

Of course, it is also possible to replace the new lamp 30 after the lamp 30 has been removed from the lamp holder 20. In this case, the gripper grips the glass portion of the lamp 30 and rotates the lamp 30, Since the lamp 30 must be separated from the lamp 21, a great deal of attention must be paid to the operation of the gripper, and if the lamp 30 is broken, the lamp replacement operation becomes impossible.

In addition, since the operation of pulling out the plug from the outlet by using the gripper has to be performed, there has been a problem that the operator needs to pay close attention.

Also, even if the lamp holder is fixed to the floor as described in the Japanese Patent No. 10-0874760 and the lamp socket is fitted to the lamp holder and separated from each other, the power cable is disconnected from the outlet when the lamp is replaced There was a cumbersome problem that accompanied the process.

At this time, since the gripper has to grip the glass portion of the lamp, there has been a problem that more attention must be paid to the lamp replacement work.

Second, since the hot cell illumination device of the related art is fixed to one side of the hot cell through the support ring 12, there is a problem that it is difficult to replace the illumination device itself.

That is, when the hot cell lighting device is used, the entire lighting device or the housing 10 must be replaced due to a failure of the lighting device itself as well as replacement of the lamp 30. In the hot cell lighting device of the related art, ) Is fixed to the inside of the hot cell, it was very difficult to separate and replace it.

Thirdly, there is a problem that the stability of the lighting device placed on the floor of the hot cell is lowered when the lighting device is placed on the floor of the hot cell for maintenance of the lighting device.

That is, the power cable 22 exposed downward from the lighting apparatus is pressed against the housing 10 to be damaged by interference between the bottom of the hot cell and the housing 10, ) Can provide anxiety.

When the power cable 22 is exposed to the side of the housing 10 without exposing downward, the power cable 22 between the bottom of the hot cell and the housing 10, Since the power cable 22 is exposed on the side surface, when the housing 10 is installed on the side of the hot cell, the power cable 22 has a high possibility of interference with the surrounding structure, The power cable 22 may be damaged due to the tilting of the cable 22.
