Abstract
An improved construction of pipeline closure with wireless positioning and warning system are disclosed. The improved pipeline closure is composed of an upper platen, an expansion body, a lower platen, a plurality of bolts, and a plurality of compression rings, on which a plurality of clamping holes arc provided for holding and fixing a cable line. A gas sensing, device is provided inside the pipeline closure to detect gas concentrations within the space inside a manhole channel when being installed in the underground manhole channel. The measured data is transferred to a monitoring device through wireless transmissions to keep monitoring gas concentrations within the manhole channel. This prevents injuries and deaths of people working inside the manhole channel due to a lack of oxygen or inhalation of harmful gases.
Description
IMPROVED CONSTRUCTION OF PIPELINE CLOSURE WITI
WIRELESS POSITIONING AND WARNING SYSTEM
BACKGROUND OF THE INVENTION
Field of the Invention The present invention relates to an improved construction of pipeline closure with wireless positioning and warning system , particularly to a pipeline closure which allows cable line to be mounted and fixed.
I() Compression rings having a wedge are provided to the closure for fixedly holding the cable line. A gas sensing device is provided on the main body of the pipeline closure fbr detecting gas concentrations inside the space of manhole channel. The detected data is transmitted to a monitoring device through wireless transmission, so that people on the ground can monitor the gas concentration state at any time inside the space of manhole channel for security processing to prevent from casualties of workers.
Description of the Prior Art As to conventional cable or pipeline constructions perlbrmed inside the channels under the ground, a plurality of pipeline closures are disposed at intervals for ensuring a cable line to be mounted fixedly. The internal axial of a conventional pipeline closure is provided with a plurality of inner pipe holes. The cable line must be individually aligned with each of the inner pipe holes for penetration. However, the distance from the entrance of manhole to the mounting place of the pipeline closure is long, and individual alignment is required in the performance of long-distance penetration. This increases the difficulty of assembly, making the pipeline closure difficult to be fixed. Further, the cable line is likely to be displaced due to the traction caused by cars driven on the road.
In addition, manhole channels of electric power and telecommunications are used as places for underground cable diffeing continuing, connection, and accommodating, as well as placing space for cable accessory equipment such as relays, care iron, and inflatable test equipment. The manhole channels are constructed of a reinforced concrete structure and are belonging to a confined construction space.
After manholes are created in the underground tunnel and laying of cable lines, electricity, telecommunications personnel usually do not need to go into and out of manholes unless cable, fiber optic equipment malfunction Is and need repair or expansion/grafting. Since the manhole channel belongs to the underground confined space, bad ventilation may exist, and harmful gases such as carbon monoxide, hydrogen sulfide, and carbon dioxide may be produced when people entering and treading mud inside the manhole channel. Since the gases are mostly colorless and odorless, the human body may not sense them based on the sense of smell.
Therefore, injuries and deaths of workers may occur frequently due to excessive inhalation of toxic gas or oxygen deficiency.
In fact, different types of mortal dangers exist in different confined spaces, but the highest percentage of dangers is gas hazards. According to the report and analysis on major occupational hazard inspection relevant
