钻孔摄影仪
borehole camera
zuankong sheyingyl钻孔摄影仪(borehole eamera)用于检查和记录钻孔内岩石裂缝、离层的空间方位和张开大小的光学仪器。它可用于矿山沉陷、大坝安全预报等。 钻孔摄影仪有刚性结构的和光导纤维的两种。如图所示是刚性结构的钻孔摄影仪,它包括管子1,位十前端及用玻璃封闭的叹望孔2.把图像反射给物镜4的反射镜子3,透镜系统5及目镜6。仪器用矿灯蓄电池供电。光导纤维钻孔摄影仪是通过多股光纤维缆将摄像头与摄像控制设备联结起来。摄像头为一可移动的抛光不锈铬钢制成的套管,内有镜头、摄像管、低噪音放大器、聚焦电机,外径32mm。~妒 钻孔摄影仪 (章J于)
