Description

Downhole periscope system Technical Field The utility model relates to the field of measurement, in particular to a set of underground pipeline wireless detection system. Background With the development of urban novel basic mapping and live-action three-dimensional construction, three-dimensional construction of underground space pipelines becomes an important part. The accurate measurement and real-time dynamic reflection of underground space pipeline types, materials, pipe diameters, burial depths, auxiliary facility positions, attributes and the like become important links of urban construction and development, and in view of the important links, the unit applies for a periscope device for wireless detection of underground pipelines, the application number is 2025204010398, and the application date is 2025, 03 and 10. However, in practical application, because the underground pipeline has a small internal space, sludge, accumulated water, harmful gas and the like, the problems of inaccurate image acquisition, insufficient light source intensity, incapability of measuring the size of a well chamber and the like exist. Disclosure of utility model The utility model aims to provide an underground periscope system, which is based on an optical principle, and realizes the non-contact acquisition of key data such as underground pipeline interior and underground imaging, pipeline trend and connection relation recognition, branch pipe viewing, well depth, buried depth, pipe diameter, well chamber size and the like by carrying a high-definition camera, a strong-light flashlight, a green light level meter and a laser range finder on a telescopic rod. The technical scheme is that the underground periscope system is characterized in that the top of a multifunctional telescopic rod is fixed on one or two stainless steel plates through an adjustable screw, a multifunctional telescopic rod body is rotationally fixed through a rotary buckle after being rotationally telescopic, the length is freely adjusted, and a green light level meter, a laser range finder and a camera are all installed on one or two stainless steel plates through an adapter. Further, when there are two corrosion resistant plates, the buckle passes through the adapter to be fixed on the corrosion resistant plate, places the highlight flashlight in the buckle, utilizes buckle bottom screw to adjust elasticity and opens the buckle. Further, when a stainless steel plate exists, the support is fixed at the lower end of the multifunctional telescopic rod, a strong light flashlight is placed in the buckle, the tightness is adjusted and the buckle is opened by utilizing screws at the bottom of the buckle, one side of the buckle is rotationally fixed with the support, and the direction of the flashlight can be adjusted through 360-degree rotation of the buckle. Further, when there is a corrosion resistant plate, the buckle passes through adjustable screw to be fixed on the corrosion resistant plate, places another highlight flashlight in the buckle, utilizes buckle bottom screw to adjust elasticity and opens the buckle. Further, the mounting positions of the green light level meter, the laser range finder and the camera can be adjusted in the up-down sequence of the two stainless steel plates. The utility model has the following beneficial effects: 1. The risk caused by the traditional limited space operation is reduced, the working time is shortened, and the working cost is reduced; 2. The non-contact acquisition of key data such as the interior and underground imaging of an underground pipeline, the identification of the trend and connection relation of the pipeline, the inspection of a branch pipe, the depth of a well, the depth of burial, the diameter of the pipe, the size of a well chamber and the like is realized; 3.
