Infrared visual detection device in goaf hole

The utility model provides an infrared visual detection device in a goaf hole, which comprises a host, and a data lead is arranged on one side of the host. The lower part of the data lead is provided with an infrared probe, and one side of the host is provided with an auxiliary guide frame structure; and a connecting guard bar structure is mounted in the middle of the auxiliary guide frame structure. The right side of the connecting screw rod on the shaft rod is longer than the left side, so that the guide pipe and the connecting screw rod can form a T shape when the upper side is not connected with the guide pipe, and the guide pipe can be prevented from easily falling into the inner side of a drill hole. 本实用新型提供一种采空区孔内红外可视探测装置，包括主机，所述的主机的一侧设置有数据导线；数据导线的下部安装有红外探头，其特征在于，所述的主机的一侧设置有辅助引导架结构；辅助引导架结构的中间位置安装有连接护杆结构。本实用新型连接螺杆在轴杆的右侧长于左侧，从而在上侧没有连接导向管时导向管与连接螺杆能够呈T型，从而能够避免导向管轻易掉落到钻孔的内侧。
