Along with the development of society, the transportation requirements of goods are higher and higher, the requirements of rain prevention, sun protection, heat preservation and the like on the endless transportation cannot be met, and the head horn is exposed in the air-filled sealed transportation process. At present, the surface of the storage and transportation box or the container is usually provided with a ventilation port, and the replacement of the gas in the box body is completed through the ventilation port, which has several problems: firstly, two sets of equipment (air extraction and air inflation) are needed and are operated separately and sequentially, the time consumption is long, and the intellectualization degree and the automation degree are not high; secondly, air suction and inflation are carried out through the same gas exchange port, the efficiency is low for a large storage box, the uniformity and consistency of the gas pressure and components in the large box body in a short time are difficult to ensure, the air is difficult to be sucked away at the position far away from the gas exchange port, and meanwhile, the fresh gas is difficult to diffuse, and the requirements can be met only by repeatedly sucking air and inflating for a plurality of times; thirdly, the gas in the box lacks an effective detection means and is difficult to be effectively controlled.
In addition to the inflatable seal transportation requirements, certain fluid media are required to be constantly rolled at an angle during transportation or storage to prevent settling or delamination from affecting product quality. In fact, the traditional commercial concrete transport vehicle (cement tank car) has provided a solution, and the vehicle-mounted motor and the gear are used for driving the tank body to rotate, so that the state and the position of products in the tank can be continuously changed. This solution, although having some advantages, also presents a number of problems: firstly, the rotating speed is too high, and the rotating angle is difficult to accurately control; the auxiliary equipment such as the motor, the electric wire and the like is very close to the tank body, so that large potential safety hazards exist for certain flammable and explosive products; and thirdly, the tank body and the vehicle body are fixed together and cannot be separated, so that the problem of protective atmosphere in the transportation process is difficult to consider.
At present, no transportation and storage device which can provide protective atmosphere and can realize regular rolling of products is available on the market.

All the electromagnetic valves, the sensors (such as a pressure gauge and a nitrogen analyzer which can only be digitally displayed), the vacuum pump and the like are electrically connected with and controlled by the PLC through leads, and an external power supply is connected with and supplies power to all the electric equipment.
The use method of the gas replacement and detection device is as follows: firstly, the methodCalibrating nitrogen analyzer (measuring range: 70% -99.99%, precision: 98-99.99 + -0.03% N)2) The method comprises the steps of respectively connecting a test pipeline with external atmosphere and pure nitrogen (an inflation gas source) after starting up and stabilizing for 3 minutes, turning a knob of a nitrogen analyzer to a calibration gear, and observing whether a test result is 79 percent (the content of nitrogen in the air) and a nominal value of the gas source. In the manual mode (the control switch on the operation panel is turned to manual operation in advance), a vacuum pumping switch is turned on, and a vacuum pump operation indicator lamp is turned on; when the pressure in the box body is lower than the lower limit of the pressure, the pressure gauge feeds back data to the PLC, and the PLC sends out an instruction to stop the operation of the vacuum pump; opening a nitrogen filling switch to fill nitrogen into the box body, feeding back data to the PLC by the pressure gauge when the pressure in the box body is higher than the upper limit of pressure, and sending an instruction to the solenoid valve to cut off the gas filling pipeline by the PLC to stop filling gas; when the purity and pressure of the nitrogen in the box body both meet the index requirements, the 'standard reaching indication' lamp is lightened to prompt the completion, and the manual vacuum-pumping and nitrogen-filling operation is stopped.
In the automatic mode (the control switch on the operation panel is turned to the automatic state in advance), the start button is pressed, and then the automatic running indicator lamp is turned on. Need not artificial intervention among the whole automatic operation process, PLC controller and each sensor cooperate jointly, accomplish bleeding, aerify and pressure, nitrogen gas purity test, the adjustment in the box automatically, stop automatically up to the back of reaching standard, light "indicating to reach standard" lamp is accomplished in order to indicate simultaneously. If the stop button or the scram button is pressed during the period, the operation is automatically stopped, and the indicator light is turned off. In the pressure fine adjustment stage at the end of the automatic mode, as the gas in the box body has a balance and stability process during inflation and air exhaust, the standard-reaching indication lamp can be turned on or off for a while and can be stabilized after a short time of minutes.
