Abstract

An environmental monitoring pipeline closure and a wireless positioning and warning system thereof are disclosed. The environmental monitoring 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 are 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.

Claims

wherein the pipeline closure is composed of an upper platen, an expansion body, and a lower platen, a plurality of clamping holes are provided in the pipeline closure for passing and fixing of a plurality of cable lines, and, a gas sensing device is provided in the main body by which gas data is detected and transmitted from a wireless communication module to a remote monitoring device for remotely monitoring the gas content in a manhole channel at any time to ensure the safety of people who work within the manhole channel, and

wherein the gas sensing device detects gas using a gas detector, the detected gas data is converted to an analog signal, amplified by a signal amplifier, undergone analog/digital data conversion through a microcontroller, and then the digitalized data is transmitted through a first wireless communication module, through Zigbee agreements and/or a wireless sensor network (WSN), to a monitoring device, and then analyzed and compared by a gas data processing APP within the monitoring device, and the compared results are displayed or a warning sound is issued.

2. The wireless positioning and warning system of the environmental monitoring pipeline closure as claimed in claim 1, wherein the monitoring device is a PDA (Personal Digital Assistant), a smart phone, or a notebook computer.

3. The wireless positioning and warning system of the environmental monitoring pipeline closure as claimed in claim 1, wherein a control center is also provided to transfer data through TCP (Transmission control protocol)/IP (Internet protocol) with the monitoring device.

4. The wireless positioning and warning system of the environmental monitoring pipeline closure as claimed in claim 1, wherein a radio frequency identification (RFID) system is provided on the pipeline closure for quickly identifying the location.

7. The wireless positioning and warning system of the environmental monitoring pipeline closure as claimed in claim 1, wherein,

the pipeline closure is further composed of a plurality of bolts and a plurality of compression rings,

the upper platen is provided with a plurality of through holes with notches and punch holes, as well as an assembly hole to assemble a gas sensing device;

the expansion body is provided below the upper platen, in which a plurality of circular through holes and sleeve holes are provided;

the circular through holes are connected with the through holes with notches of the upper platen;

the compression rings are C-shaped ring body with notches, on which a wedge is provided in the upper end for increasing a tensile clamping force against the cable line, the lower end being used for being sleeved into the circular through hole of the expansion body, its outer wall being provided with a stepped portion by which the through holes with notches on the upper platen are sleeved and fixed into the stepped portion of the compression rings simultaneously when the upper platen is assembled with the expansion body;

the surface of the lower platen relative to the circular through hole of the expansion body is provided with a plurality of through holes with notches;

the upper end relative to the sleeve holes of the expansion body is provided with bumps by which the upper end is inserted into the sleeve hole and assembled with the expansion body; and

the internal of the bump is provided with a punch hole;

whereby the whole body is adapted to be assembled into one when the bolts pass through each of the punch holes, and the interlinked through holes with notches, compression rings, and through holes with notches constitute the interlinked clamping holes for clamping the cable line.

5. A wireless positioning and warning system of an environmental monitoring pipeline closure,

wherein the pipeline closure is composed of an upper platen, an expansion body, and a lower platen, a plurality of clamping holes are provided in the pipeline closure for passing and fixing of a plurality of cable lines, and, a gas sensing device is provided in the main body by which gas data is detected and transmitted from a wireless communication module to a remote monitoring device for remotely monitoring the gas content in a manhole channel at any time to ensure the safety of people who work within the manhole channel, and

wherein the pipeline closure is a direct reading pipeline closure whose surface color is changed when exposed to a certain amount of the gas concentration due to the selection and use of inductive materials or sensing pigments so as to provide timely protection for on-site workers.

6. The wireless positioning and warning system of the environmental monitoring pipeline closure as claimed in claim 5, wherein the direct reading pipeline closure also has a high temperature color display function, whereby contact between internal media of the pipeline closure and harmful gases causes a color reaction to be produced on the pipeline closure due to attachment of chemical substances on the internal media.
