Description
Technical field
The utility model relates to underground cable construction aid, is specially a kind of cable tunnel sight glass.
Background technology
Along with urbanization process is accelerated, the quantity of laying of underground cable also grows with each passing day, and just becomes an important routine work to the Inspection and maintenance of cable.In reality, most cable is all laid in tunnel, and minority adopts direct-buried mode, and the cable in tunnel just needs people and enters Inspection and maintenance.
Make maintainer be difficult to enter because the reasons such as construction quality, long operational time, outside destroy can cause the serious ponding in cable tunnel, meanwhile, ponding can cause again harmful gas to produce, and more threatens to personal safety.Therefore, prejudge cable tunnel inner case and the safety of personnel is just seemed most important.Fibre-optical probe can be used at present to observe in cable tunnel, and this equipment costly, and needs to carry accurate heavy display, needs power supply supply simultaneously, unusual inconvenience in practical application.Therefore a kind of with low cost, structure simple cable tunnel viewing tool is starved of.
Summary of the invention
The utility model, for solving current cable tunnel viewing tool awkward technical matters with high costs, provides a kind of cable tunnel sight glass.
The utility model adopts following technical scheme to realize: a kind of cable tunnel sight glass, comprises a vertical tube, and the two ends up and down of vertical tube are bent into horizontal; Composition periscope light path that upper and lower bending place is equipped with catoptron and two-face mirror cooperatively interacts; Described riser middle is provided with support; Vertical tube bottom is Collapsible structure.
In real work, when needing the situation of checking in cable tunnel, the utility model is placed on inspection chamber porch, support is supported in inspection chamber well head, vertical tube lower end is Collapsible structure, can go deep in tunnel from inspection chamber porch, also can be deep under ponding, judge the situation in the depth of water and water by periscope light path.
Further, support is arranged on vertical tube by a horizontally disposed bearing seat; Be connected by bearing between vertical tube with bearing seat; Vertical tube is provided with turning handle.
The inner ring of bearing is fixedly connected with vertical tube, and the outer ring of bearing is fixed in bearing seat; Just can vertical tube be rotated by rotary handle, and then the situation in 360 ° of observation inspection chambers.
Further, described vertical tube comprises vertical tube and lower vertical tube; Lower vertical tube from bottom to top activity is nested in vertical tube inside; Described bearing seat is arranged on vertical tube; Turning handle is located on vertical tube; Upper vertical tube is also provided with the bolt for locating lower vertical tube.
Lower vertical tube is nested in vertical tube, the upper and lower telescopic adjustment of realization that can be convenient, flexible, and bolt is used for positioning lower vertical tube, makes it remain on a position, is convenient to observe.
Further, outside the horizontal mouth of pipe of lower vertical tube, border is provided with LED group lamp.
LED group lamp is used for tunnel internal illumination, is beneficial in dark surrounds and observes.
Vertical tube described in the utility model adopts scalable design, is furnished with rotary handle, support, LED group lamp.During use, sight glass is fixed on well head by useable holder, and by stretching, sight glass is goed deep into (collapsing length can have multiple choices) in tunnel, rotary handle can control the range of observation of 360 °, observe end and be furnished with LED illumination, can accurate orientation problem place in the dark.Whole apparatus structure is simple, uses assembling all very convenient, and with low cost, reliability and durability.
