Abstract
The utility model relates to a ventilation display device for underground pipeline safety. The ventilation display device comprises an underground pipeline. A fan fixing box is installed on the outer side of the pipe wall in the length direction of the underground pipeline. A fan is installed inside the fixing box. A control panel is installed at the bottom of a well lid and controls the fan. A gas concentration sensor is installed on the outer wall of the pipeline. The gas concentration sensor is provided with a socket through a wire, and the socket is fixed into a vertical well below the well lid. The ventilation display device further comprises a displayer. The displayer is connected with a USB plug through a wire, and the USB plug is connected with the socket in a plug mode. The ventilation display device for underground pipeline safety has the advantages that the fan is started by the control panel to exhaust air forcibly, data collected by the gas concentration sensor are displayed on the display screen, and then whether the concentration of gas under the well allows a person to go down to the well or not can be determined, so that the ventilation display device is convenient to use.
Description
Technical field
The utility model relates to a kind of ventilation display unit for underground pipeline safety, belongs to safety article field.
Background technology
In the time carrying out the maintenance of underground pipeline, the person of needing repairing goes into the well, due to underground be that air flow property is poor, be unfavorable for gas diffusion, cause gas concentration larger, although maintenance person is gone into the well after conventionally distributing a period of time, just carry out according to sensation, whether the gas concentration that can not learn down-hole is applicable to the work of going into the well, and has potential safety hazard.
Summary of the invention
For overcoming the defect of prior art, the utility model provides a kind of ventilation display unit for underground pipeline safety, the technical solution of the utility model is: a kind of ventilation display unit for underground pipeline safety, comprise underground pipeline, the outside of the tube wall on the length direction of this underground pipeline is provided with fan fixed case, in described fixed case, fan is installed, described fan is powered by portable power source, on the side plate of described fan fixed case, is provided with air inlet port; The outside of described pipeline is also provided with the exhaust duct be arrangeding in parallel with pipeline, and one end of this exhaust duct communicates with fixed case, and the other end extends in the vertical shaft of bottom of well lid, and control panel is arranged on the bottom of well lid, and fan is controlled; On the outer wall of described pipeline, gas concentration sensor is installed, described gas concentration sensor is provided with socket by wire, and this socket is fixed in the vertical shaft of well lid bottom; Also comprise a display, this display is connected with USB plug by wire, and described USB plug and socket plug.
The utility model has the advantages that: start fan by control panel and carry out powerful air draft, the data that then gather according to gas concentration sensor show to learn whether the concentration of mine gas is applicable to going into the well on display screen, easy to use.
Brief description of the drawings
Fig. 1 is agent structure schematic diagram of the present utility model.
Detailed description of the invention
Further describe the utility model below in conjunction with specific embodiment, advantage and disadvantage of the present utility model will be more clear along with description.But these embodiment are only exemplary, scope of the present utility model are not formed to any restriction.It will be understood by those skilled in the art that and do not departing under spirit and scope of the present utility model and can the details of technical solutions of the utility model and form modified or be replaced, but these amendments and replacement all fall in protection domain of the present utility model.
Referring to Fig. 1, the utility model relates to a kind of ventilation display unit for underground pipeline safety, comprise underground pipeline 1, the outside of the tube wall on the length direction of this underground pipeline 1 is provided with fan fixed case 2, fan 4 is installed in described fixed case 2, described fan 4 is powered by portable power source, on the side plate of described fan fixed case 2, is provided with air inlet port 3; Air inlet port flare, for large-scale water conservancy diversion gas; The outside of described pipeline 1 is also provided with the exhaust duct 5 be arrangeding in parallel with pipeline 1, one end of this exhaust duct 5 communicates with fixed case 2, the other end extends in the vertical shaft 9 of bottom of well lid 8, and control panel (not shown) is arranged on the bottom of well lid 8, and fan is controlled; Gas concentration sensor 6 is installed on the outer wall of described pipeline 1, and described gas concentration sensor 6 is provided with socket by wire, and this socket is fixed in the vertical shaft 9 of well lid bottom; Also comprise a display 7, this display 7 is connected with USB plug by wire, and described USB plug and socket plug.
The utility model when in use, is first opened well lid, will be plugged on socket with the display of USB plug, start control panel and utilize fan to carry out air draft, the gas concentration of down-hole is declined, in the time reaching suitable definite value, can go into the well, ensure operator's safety; After finishing using, display can be taken away.
