Description
Technical Field
The invention relates to a plugging device and a working method thereof, in particular to an emergency plugging device of a dangerous chemical tank truck and a working method thereof.
Background
The chemical industry occupies an important position in the national economy of China. However, hazardous chemical transport is always in a special transportation industry. Compared with transportation modes such as railway, waterway, aviation and pipeline, the road transportation mode has the advantages of economy, rapidness, flexibility and the like, and has high transportation efficiency, so that the road transportation becomes the most main transportation mode in dangerous chemical transportation. However, dangerous chemicals are greatly influenced by uncertain factors in the road transportation process and have unstable chemical properties, so that accidents such as leakage, corrosion, fire and explosion are extremely easy to occur. In recent years, dangerous chemical leakage accidents frequently occur, and toxic gas and inflammable gas are easy to diffuse in a short time, so that personnel poisoning accidents are caused, and serious explosion accidents occur once the dangerous chemical leakage accidents come into contact with a fire source, so that the life health of surrounding personnel is threatened; for liquid leakage of dangerous chemicals, the flow diffusivity is strong, and if the control or treatment is improper, fire sources are often encountered in unexpected places so as to cause accidents such as fire explosion and the like; for solid leakage of dangerous chemicals, static electricity is easily generated when the dangerous chemicals are shocked by vibration and tank wall impact, so that explosion is caused. Therefore, the quick and effective emergency plugging treatment is very important by utilizing safety measures and technical means in the road transportation process of dangerous chemicals.
At present, some technical means and special devices exist in the aspect of plugging the dangerous chemical tank truck. Such as chinese patent publication No. CN203294607U, which provides a manual leak stopper comprising a leak stopping retention screw, a leak stopping cap, a pressure hand wheel, and the like. Because of the special attribute of the dangerous chemical, the life safety of operators is easily endangered, but the device is operated manually, does not intelligently sense to leak the operators, and has slower leak stopping speed. In addition, the plugging device has poor adaptability, can only solve a small-range leakage port, and cannot perform integral plugging on the surface of the tank body. In addition, the Chinese patent with the publication number of CN209943502U is a glue injection type plugging device, and the glue is supplied by arranging a fixed pipe so as to achieve the effect of extruding and plugging a leakage part. However, the device is generally suitable for flange leakage, and can not perform plugging operation on a vehicle tank body, and dangerous chemicals often cause leakage accidents due to the fact that the tank body is impacted, pierced or corroded in the transportation process. In addition, the glue injection material cannot be supplied in time, and the chemical property of the glue injection material can react with hazardous chemicals, so that a more serious secondary accident is generated. The leakage blocking mode is one-time leakage blocking, and when the later period of the leakage opening of the tank body is repaired, grouting at the grouting part is required to be removed, and then the disassembly and the repair are carried out, so that the working flow is complex.
The plugging mode is only suitable for small-range leakage, manual operation is needed, and the defects that the plugging effect is slow, the later repair work of a leakage port is complex and the like exist. In order to ensure the running safety of the dangerous chemical tank truck in the transportation process, the damage and the loss caused by leakage accidents are reduced and avoided as much as possible, and therefore, the emergency plugging device which is safe and reliable and can rapidly and effectively solve the problem of dangerous chemical leakage in the transportation process is an urgent need to be solved at present.

C. in the normal transportation process of the tank truck, each monitoring probe group monitors the concentration value of dangerous chemical substances on the outer surface of the tank truck in real time and feeds back monitoring data to the control device, the control device compares the monitoring data with stored data, and if the concentration value of the dangerous chemical substances of each monitoring probe does not exceed a set threshold value, the control device judges that the tank truck is in a normal state and continues to monitor; d, if the concentration value of the dangerous chemical of any monitoring probe exceeds a set threshold value, the control device judges that the tank body of the tank truck is in a leakage state, and the step D is entered;
D. the control device firstly determines a monitoring probe group in which the monitoring probe is positioned, and further obtains four electric control valves of the monitoring probe group corresponding to the same bracket group; the control device sends out a control instruction to enable the four electric control valves to be opened, inert gas enters the two gas curtain gas guide pipes in the bracket group from the gas supply pipe, and then is sprayed out from the gas outlet holes of the two gas curtain gas guide pipes, and as the gas outlet holes of the two gas curtain gas guide pipes are oppositely arranged, an air flow curtain is formed on the outer surface of the tank body between the bracket group, the leakage points are primarily plugged, the leakage speed of dangerous chemicals is reduced, and the concentration of the leaked dangerous chemicals is diluted; simultaneously, the two air curtain air ducts enable inert gas to enter the air bags of the two circular tube type brackets in the same bracket group through the air bag connecting pipe, so that the two air bags are inflated, at the moment, the two air bags start to expand, one ends with magnetic materials extend out of the air bag extending openings, and because the air bag extending openings of the two circular tube type brackets in the same bracket group are oppositely arranged, and because the magnetic materials at the end parts of the two opposite air bags are attracted mutually, the air bags in the two circular tube type brackets extend rapidly and oppositely along the outer surface of the tank body until the two opposite air bags are contacted mutually and the magnetic materials of the two air bags are attracted mutually, at the moment, the two air bags wrap the outer surface of the tank body between the bracket group, so that pressure is applied to the leakage point to seal and leak the dangerous chemical is prevented from continuously leaking;
E. when the dangerous chemical in the tank body is safely discharged and the leakage point of the tank body needs to be repaired, the air pump is firstly used for communicating the air supply pipe, inert gas in the air bag is pumped through the air supply pipe, the air curtain air duct and the air bag connecting pipe until the inert gas is completely pumped out, and after the two air bags which are mutually attracted are separated, the two air bags are respectively folded and contracted in the two circular pipe type supports from the air bag extending outlets of the two circular pipe type supports, so that the air bag recovery and resetting work is completed, and the leakage point can be repaired at the moment.
