Embodiment
The utility model is described in further detail below by embodiment:
See also Fig. 1, this figure is the structural representation of quiet base unit one better embodiment of the utility model high-precision optical gyro incubator.In the present embodiment, the quiet base unit of described high-precision optical gyro incubator, it comprises quiet pedestal 1, incubator 2, base clamp 3 and rotating disk 4.Wherein, base clamp 3 is cylindrical, and these base clamp 3 one ends are in incubator 2, and its top is quiet pedestal 1, and the other end passes incubator base station 5 and links to each other with rotating disk 4, and this rotating disk 4 is arranged on the end pier 9, and this end pier 9 is the Dali stone pier.Be provided with heat-barrier material 6 between base clamp 3 and the incubator base station 5 in addition, this heat-barrier material 6 is flexible heat insulation foam, and it closely contacts around base clamp 3 and with the inside surface of incubator base station 5 center pits.The described in addition base clamp 3 that is positioned at incubator base station 5 is divided into two parts, be folded with heat insulation post 7 between two parts base clamp, this heat insulation post 7 is made by the entity heat-barrier material, and it is fastenedly connected by the some screw locking realizations in base clamp 3 screw channels 8 and two parts base clamp 3.
In the present embodiment, heat-barrier material 6 and heat insulation post 7 that the quiet base unit of described high-precision optical gyro incubator is arranged between base clamp 3 and incubator 2 inside surfaces can be isolated incubator effectively by the heat transferred between the base clamp 3 and the external world.Because heat insulation foam is a flexible material, and it fits tightly between base clamp 3 and incubator 2, therefore have vibration isolating effect simultaneously, can reduce the influence of external disturbance and incubator 2 vibration of compressor gyro.Therefore the quiet base unit of the utility model high-precision optical gyro incubator can be realized vibration isolation in heat insulation, disturb thereby help eliminating, realization is to gyro zero inclined to one side accurate measurement, comprise zero measurement of average partially, and zero stability, zero measurement of laying particular stress on indexs such as renaturation and random walk coefficient partially.
