[0002] A hot room is a special laboratory for handling or processing highly radioactive materials. It usually has thick concrete shielding walls for radiation shielding and a special radiation-proof observation window for observation from the outside of the hot room. Operators need to use manipulators to operate items inside the hot room. Hot rooms have high requirements for internal lighting. Metal halide lamps such as sodium lamps and dysprosium lamps are commonly used for lighting inside hot rooms. This type of lighting has high power and brightness, and can well meet the lighting requirements inside the hot room.

[0003] Hot chamber lighting lamps usually use glass lampshades to isolate the lighting lamps from the air inside the hot chamber to prevent radioactive contamination. Since metal halide lighting lamps generate a lot of heat and the glass lampshade is a closed environment, the heating of the lighting lamp will cause the temperature inside the glass lampshade to be very high, which will increase the light decay of the lighting lamp and reduce the service life of the lighting lamp. In addition, the lighting lamp needs to be frequently inspected and replaced, which increases the burden on maintenance personnel and also brings certain radiation risks to maintenance personnel.

[0028] In the following detailed disclosure, these embodiments are fully described with reference to the accompanying drawings. In order to make the technical scheme of the present invention more clear and specific to those skilled in the art, the implementation methods described below are not limited to this.

[0030] In the description of the present invention, it is necessary to understand that the directions or positional relationships indicated by the terms "up", "down", "left", "right", "front", "back", etc. are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or unit referred to must have a specific direction, be constructed and operated in a specific orientation, and therefore, cannot be understood as a limitation on the present invention.

[0031] The first aspect of the present invention, as Figure 1-3 As shown, a cooling device for a hot chamber lighting lamp is provided, comprising a bracket assembly 1 and a lamp 2 connected to the bracket assembly 1, a lampshade 3 being provided on the lamp 2, the lamp 2 and the lampshade 3 being both located in the hot chamber, a hole 4 for the lamp 2 to pass through is provided in a radiation-proof wall 10 of the hot chamber, the bracket assembly 1 is arranged in the hole 4 for supporting the lamp 2, the hole 4 forms an air inlet channel 6 and an air outlet channel 7 connected to an inner chamber of the lampshade 3 through the bracket assembly 1, and an exhaust channel 5 connected to the air outlet channel 7 is provided in the radiation-proof wall 10.

[0032] The heat chamber lighting lamp cooling device is connected to the lamp 2 through a bracket assembly 1. The bracket assembly 1 is placed in a channel 4 and divides the channel 4 into an air inlet channel 6 and an air outlet channel 7. The gas outside the heat chamber enters the inner chamber of the lampshade 3 through the air inlet channel 6, and the hot air is discharged through the air outlet channel 7, and is discharged from the exhaust channel 5 to take away the hot air in the lampshade 3, so that the outside world can continuously supply air to the lamp 2 for cooling, reduce the temperature of the working environment of the lamp 2, increase the service life of the heat chamber lamp 2, reduce the frequency of maintenance or replacement, reduce radiation damage to maintenance personnel, and have higher safety.

[0033] In one possible implementation, Figure 1 As shown, the air flow can sequentially pass through the air inlet channel 6, the inner chamber of the lampshade 3, the air outlet channel 7 and the exhaust channel 5 to lead out the hot air in the inner chamber of the lampshade 3.

[0034] The present embodiment provides a structure of a channel 4 and a bracket assembly 1, wherein a lamp 2 is connected to one end of the bracket assembly 1, and the lamp 2 is sent into the lampshade 3. At this time, the bracket assembly 1 is placed in the channel 4, and the bracket assembly 1 divides the channel 4 into an air inlet channel 6 and an air outlet channel 7. The air inlet channel 6 and the air outlet channel 7 can only interact with each other through the inner chamber of the lamp 2, that is, the external gas passes through the air inlet channel 6, the inner chamber of the lampshade 3, the air outlet channel 7 and the exhaust channel 5 in turn. Continuous ventilation can lead out the hot air around the lamp 2, thereby achieving the effect of cooling the inner chamber of the lampshade 3.

[0035] Among them, a negative pressure system can be connected to the exhaust channel 5, and cooling air can be sucked in through the provided negative pressure air inlet channel 6 and transported to the position of the lamp 2 for ventilation and cooling, and then the heated air is discharged from the exhaust channel 5 through the air outlet channel 7.

[0036] Among them, the channel 4 is pre-buried in the radiation proof wall 10 of the hot chamber, and the exhaust duct is also pre-buried in the radiation proof wall 10 of the hot chamber. The exhaust duct is arranged as close to the inner side of the radiation proof wall 10 as possible, so that the exhaust duct has a sufficient distance from the radiation proof wall 10. When the exhaust duct is contaminated with radioactivity, the radiation proof wall 10 still maintains a good radiation shielding effect for the exhaust duct. The radiation proof wall 10 is usually a concrete shielding wall.

[0037] In one possible implementation, Figure 1-Figure 3 As shown, the bracket assembly 1 includes a spindle 11, a fin 14 and a wind shield 15, one end of the spindle 11 is used to connect with the lamp 2, the fin 14 is arranged on the spindle 11, and the wind shield 15 is arranged at the end of the fin 14 away from the lamp 2, the fin 14 and the wind shield 15 divide the channel 4 into an air inlet channel 6 and an air exhaust channel 5, and the air inlet channel 6 and the air exhaust channel 5 can only be connected through the inner chamber of the lampshade 3.

[0038] Among them, the bracket assembly 1 is installed in the channel 4, and is used to install the lamp 2 and push the lamp 2 to the lampshade 3 in the hot chamber. The bracket assembly 1 can use the main shaft 11 as a support, and install the fins 14 and the wind shield 15 on the main shaft 11. The wind shield 15 is arranged on the fins 14 and extends in the direction of the exhaust channel 5, so that the fins 14 and the wind shield 15 cooperate to divide the channel 4 into an air inlet channel 6 and an air outlet channel 7. The air inlet channel 6 is located on the side of the fins 14 and the wind shield 15 away from the exhaust channel 5, and the air outlet channel 7 is located on the side of the fins 14 and the wind shield 15 facing the exhaust channel 5, and the exhaust channel 5 is connected with the air outlet channel 7.

[0039] Among them, there can be two fins 14, which are arranged on the core shaft 11, and the angle between the two fins 14 is 90°-180°. The two fins 14 can be arranged on both sides of the core shaft 11 along the same plane, or they can be arranged at an angle. One end of the wind shield 15 is connected to one fin 14, and the other end of the wind shield 15 is connected to another fin 14. The shape of the wind shield 15 is set according to the cross-sectional shape of the channel 4. When the cross-sectional shape of the channel 4 is circular, the wind shield 15 can be semicircular or fan-shaped.

[0040] Among them, the outer edge of the fin 14 cooperates with the small gap between the inner wall of the channel 4, and the outer edge of the wind shield 15 cooperates with the small gap between the inner wall of the channel 4, which makes it easy to send the fin 14 and the wind shield 15 into the channel 4. The small gap between the fin 14 and the wind shield 15 and the channel 4 has little effect on the ventilation and cooling effect.

[0041] It is understandable that the mandrel 11 may be a round tube structure, the interior of the round tube is used for threading cables, and other components are connected in series through the mandrel 11.

[0042] Among them, Figure 1 As shown, the outer edge of the fin 14 contacts the inner wall of the hole 4, and the outer edge of the wind shield 15 contacts the inner wall of the hole 4. The outer edge of the fin 14 and the outer edge of the wind shield 15 are both in contact with the inner wall of the hole 4, which can avoid air leakage between the air inlet channel 6 and the air outlet channel 7, and further improve the ventilation and cooling effect.

[0043] The fins 14 and the wind shield 15 can be made of elastic materials to ensure that the fins 14 and the wind shield 15 are in contact with the duct 4, thereby improving the sealing between the air inlet duct 6 and the air outlet duct 7 and improving the ventilation and cooling effect.

[0044] In one possible implementation, Figure 1-Figure 3 As shown, the bracket assembly 1 also includes a flow regulating plate 16, which is arranged on the core shaft 11. The flow regulating plate 16 is adapted to the wind shield 15. The flow regulating plate 16 can move to adjust the minimum cross-sectional size of the air inlet channel 6 to adjust the gas flow of the air inlet channel 6.

[0045] Among them, the flow regulating plate 16 is arranged to cooperate with the wind shield 15 to block the air inlet channel 6, that is, the flow regulating plate 16 can move and adjust the gap between it and the wind shield 15, so as to achieve the effect of adjusting the minimum cross-sectional size of the air inlet channel 6, and then adjust the gas flow of the air inlet channel 6.

[0046] Among them, the flow regulating plate 16 can be set on the main shaft 11, and the flow regulating plate 16 can complement the shape of the wind shield 15, that is, the flow regulating plate 16 and the wind shield 15 can both be semicircular, or the flow regulating plate 16 and the wind shield 15 are both fan-shaped and have complementary angles, and the flow regulating plate 16 can rotate with the main shaft 11 as the rotation center to adjust the non-overlapping area with the wind shield 15, and the two can be fixed by fasteners such as nuts to achieve the function of adjusting the gas flow rate of the air inlet channel 6.

[0047] Among them, the flow regulating plate 16 can be set on the main shaft 11, and the flow regulating plate 16 can complement the shape of the wind shield 15, that is, the flow regulating plate 16 and the wind shield 15 can both be semicircular, or the flow regulating plate 16 and the wind shield 15 are both fan-shaped and have complementary angles, and the flow regulating plate 16 can move along the length direction of the main shaft 11 to adjust the gap distance with the wind shield 15, and the two can be fixed by fasteners such as nuts to achieve the function of adjusting the gas flow rate of the air inlet channel 6.

[0048] Among them, the main shaft 11 may include a first pipe section and a second pipe section that are connected, the wind shield 15 is arranged on the first pipe section, and the flow regulating plate 16 is arranged on the second pipe section. The flow regulating plate 16 can be driven to rotate or move by rotating or stretching the second pipe section, that is, the position of the flow regulating plate 16 can be adjusted by simply operating the end of the main shaft 11 away from the lamp 2, thereby adjusting the gas flow in the air inlet channel 6.

[0049] In one embodiment, a first support plate 12 and a second support plate 13 are axially arranged on the core shaft 11, and ventilation holes for air flow are opened on the first support plate 12 and the second support plate 13. The first support plate 12 and the second support plate 13 are adapted to the channel 4 to support and limit the core shaft 11.

[0050] Among them, the shapes of the first support plate 12 and the second support plate 13 are adapted to the cross-sectional shape of the channel 4, and the first support plate 12 is arranged at one end of the core shaft 11 for installing and fixing the lamp 2, and the outer diameters of the first support plate 12 and the second support plate 13 are basically the same as the inner diameter of the channel 4, and are used to support the core shaft 11 in the channel 4, so that the bracket assembly 1 remains in a centered position in the channel 4, and the core shaft 11 basically coincides with the axis of the channel 4.

[0051] Among them, Figure 3 As shown, ventilation holes are provided on the first support plate 12 and the second support plate 13 for air flow to pass through.

[0052] In one possible implementation, Figure 1-Figure 3 As shown, the bracket assembly 1 further includes a handle 17 , which is disposed at an end of the spindle 11 away from the lamp 2 .
