Like elements in the various figures are denoted by the same or similar reference numerals. For purposes of clarity, the various features in the drawings are not necessarily drawn to scale.
The following describes in detail a specific embodiment of the present invention with reference to fig. 1 and 2.
The invention provides a movable gas supply device, which comprises a movable platform 10 and a plurality of gas storage container groups arranged on the movable platform 10, wherein each gas storage container group respectively comprises a gas cylinder (9) and a gas storage tank (3), the gas storage tank 3 is provided with a gas inlet pipe 4 and a gas outlet pipe 5, and the gas storage tank 3 is communicated with the gas cylinder 9 through the gas inlet pipe 4; and the air inlet pipe 4 is provided with a control valve 8 for controlling the air bottle 9 to convey air to the air storage tank 3.
Wherein, each gas storage container group is used for storing different gases respectively, uses when supplying the site operation. Each gas storage tank 3 stores different gases, such as nitrogen, argon, carbon dioxide or oxygen, and the like, and the different gases are conveyed to construction gas equipment through an output pipe, so that the practicability is high.
Preferably, at least two gas bottles 9 are arranged on each gas storage tank 3, and each gas bottle 9 is communicated with the gas storage tank 3 through the respective gas inlet pipe 4. In this embodiment, every gas holder 3 communicates two gas cylinders 9, and two gas cylinders 9 can carry out the air feed to gas holder 3 simultaneously, also can carry out the air feed in turn, and when the gas in one of them gas cylinder 9 was not enough, can last the air feed by another gas cylinder 9, change the gas cylinder 9 that is not enough, have guaranteed incessant air feed, improve work efficiency.
in this embodiment, each of the air outlet pipes 5 is provided with the control valve 8, the air outlet pipe is used for communicating with construction gas equipment, and the control valve 8 on the air outlet pipe 5 is used for controlling the air storage tank 3 to convey air to the construction gas equipment. The construction gas equipment in the present embodiment is, for example: welding gas equipment or some gas pipelines.
In this embodiment, the system further comprises an electric control cabinet, wherein the electric control cabinet is composed of a power supply 1 and a PLC control cabinet 2; the control valves 8 on the air inlet pipe 4 and the air outlet pipe 5 are electrically connected to the PLC control cabinet 2, and the PLC control cabinet 2 is used for controlling the opening or closing of the control valves 8.
in this embodiment, the air storage tank 3 and the air inlet pipe 4 are both provided with pressure transmitters 6, and the pressure transmitters 6 are respectively electrically connected to the PLC control cabinet 2; wherein, the pressure transmitter 6 on each air inlet pipe 4 corresponds to one control valve 8. Each pressure transmitter 6 monitors the gas pressure in the gas storage tank 3 and each gas inlet pipe 4 in real time and feeds the gas pressure back to the PLC control cabinet 2 in real time, and when the pressure transmitter 6 reaches a set value in the PLC control cabinet 2, the PLC control cabinet 2 sends a signal to the control valve 8 corresponding to the pressure transmitter 6 to control the pressure transmitter to open or close.
