DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a detaching mechanism for a device mounted on a satellite, and more particularly, a thermal filler is attached to a mounting surface of the mounted device in order to radiate heat generated from the mounted device to a structure of the satellite. The present invention relates to a detachment mechanism for a device mounted on a satellite.

[0002]

2. Description of the Related Art As shown in FIG. 4, a conventional satellite-mounted device radiates heat generated inside the device.
(See reference numeral 57).
For this reason, in order to largely radiate the internal heat of the device to the satellite structure, a thermal filler 52 (for example, a silicon-based adhesive or a filler) is applied between the mounting surface of the on-board device 51 and the satellite structure 53. The heat conduction between the equipment and the satellite structure is increased by securing a large contact area of the equipment mounting surface.

[0003]

As described above, the conventional satellite-mounted equipment has a thermal filler applied between the equipment mounting surface and the satellite structure. For this reason, the equipment and the satellite structure are stuck together via the thermal filler, and when it becomes necessary to remove the equipment from the satellite structure, there has been a disadvantage that it is very difficult to remove the equipment.

[0004]

SUMMARY OF THE INVENTION It is an object of the present invention to provide a detaching mechanism for a satellite-mounted device capable of remedying the drawbacks of the prior art and, in particular, for relatively easily removing the device from the satellite structure. And

[0005]

According to the present invention, a concave groove is provided on a contact surface of a satellite-mounted device with an artificial satellite structure, and a predetermined length is set in the concave groove from both ends of the concave groove. Equipped with a lever member for removal by protruding. Further, the adhering the artificial satellite equipment and the artificial satellite structure except the concave groove in a thermal filler, concave described above removal for lever member
It is configured to be arranged in the groove . This achieves the purpose described above.

[0006]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below with reference to FIGS. In the embodiment shown in FIGS. 1 to 3, a concave groove 5 is provided on a contact surface of the satellite-mounted device 1 with the satellite structure 3. In the concave groove 5, a lever member 4 for removal is provided so as to project a predetermined length from both ends of the concave groove 5. The above-described artificial satellite mounted device 1 and the artificial satellite structure 3 except for the concave groove 5 are adhered by the thermal filler 2. Further, for removal lever member 4 is arranged in a loosely concave groove 5.

This will be described in more detail. FIG. 1 shows that a satellite-mounted device 1 includes a thermal filler 2 on an artificial satellite structure 3.
(For example, the state which attached via the silicone adhesive or the thin layer of a silicone filler) is shown.

Then, to remove the mounted device 1 from the structure 3, first, as shown in FIG. 3A, the lever member 4 for removal is moved in the direction of reference numeral 6 in the figure. At this time, as shown in FIG. 2, since there is a clearance between the pry lever member 4 and the groove 5, a part of the pry lever member 4 is not in contact with the support <br/> Maru-filler 2 from the fact that the contact <br/> area as shown is small compared to the mounting apparatus 1, the adhesion between the thermal filler 2 is rather weak, it is detached for lever member 4 for the Fig. 3 (a) It can be easily moved in the direction of reference numeral 6 in the figure.

Further, as shown in FIG. 3A, the lever member 4 for removal is moved in the direction of reference numeral 6 in the figure, and one end of the lever member 4 for removal is moved to near the center of the mounted device 1. Subsequently, as shown in FIG. 3 (B), or lift the other end of the pry lever member 4 in the direction of reference numeral 6 in FIG.
Et al., Te This principle easily mounted device 1 a satellite structure 3
Can be removed from.

Further, if not remove the mounting device 1 from the satellite structure 3, its removal for lever member 4 for weight reduction at the time of the satellite flight direction shown in FIG. 3 (A)
It may be moved as it is and pulled out from the bottom surface of the mounted device 1.

[0011]

Since the present invention is constructed and functions as described above, according to the present invention, the on-board equipment having the thermal filler attached thereto can be easily removed from the satellite structure by the action of the lever member for removal and the groove of the on-board equipment. It is possible to provide an unprecedented excellent detachment mechanism for a device mounted on an artificial satellite that can be detached.
