The utility model has the advantages that, operating personnel can advance the installation work such as mouth-to-mouth, welding, nondestructive test, anticorrosive repaired mouth in sealing the floating bin, very big improvement operating personnel's security and work efficiency.
Description
Technical Field
The utility model relates to a be used for welded to seal and float storehouse, in particular to seal and float storehouse with emergent function.
Background
The applicant builds a Zhejiang petrochemical 4000 ten thousand tons/year refining integrated water supply and drainage and a fire-fighting pipe network in a secondary oil refining area and meets with abundant underground water, more dead mouths and fractures cannot be connected, the closed floating bin for underwater welding operation aims to solve the problem that in the laying and installation process of underground pipelines, the underwater environment or the environment which cannot be supported and easily collapses limits the installation work problems of pipeline alignment, welding, nondestructive testing, anticorrosion joint filling and the like, the occupation and consumption of temporary electricity resources are reduced, but the existing closed floating bin has no emergent function and is mainly judged by operators to the safety of the closed floating bin, for example, the carbon dioxide exceeds the standard, and the safety of the operators is not facilitated.
Disclosure of Invention
The utility model provides a seal and float storehouse with emergent function, operating personnel can seal and float storehouse interior pipe orifice of advancing installation work such as mouthful, welding, nondestructive test, anticorrosive repaired mouth, very big improvement operating personnel's security and work efficiency.
The technical scheme of the utility model is that the closed floating bin with emergency function comprises a hollow sleeve, two ends of the sleeve are respectively provided with an annular inflatable ring, the upper end of the sleeve is provided with an emergency access door, and the emergency access door is controlled by an emergency electric control cylinder;
the sleeve upper end be equipped with inlet channel, exhaust passage inlet channel be equipped with the air exhauster exhaust passage be equipped with carbon dioxide concentration detector on the exhaust passage, carbon dioxide concentration detector pass through the controller with emergent automatically controlled cylinder be connected.
Further, the carbon dioxide concentration detector is connected with the alarm through the controller.
Further, the air inlet channel is communicated with an induced air pipe through the exhaust fan, the induced air pipe is arranged inside the sleeve, and an air outlet of the induced air pipe is close to the lower surface of the inner wall of the sleeve.
And further, a liquid level sensor is arranged at the air outlet of the induced air pipe and is connected with the emergency electric control cylinder through a controller.
The utility model has the advantages that, 1) the carbon dioxide concentration detector is real-time to be monitored the gas concentration of exhaust gas's carbon dioxide, and after the gas concentration of carbon dioxide exceeded standard, emergent passway door was opened to the emergent automatically controlled cylinder of controller control, and fresh air got into behind the opening emergent passway door, can reduce carbon dioxide concentration fast, makes things convenient for operating personnel to escape simultaneously, or the rescue personnel gets into fast.
2) The carbon dioxide concentration detector is connected with the alarm through the controller, when the carbon dioxide concentration detector detects that the carbon dioxide concentration exceeds the standard, the controller starts the alarm, and after the alarm is started, an operator is reminded of leaving away immediately, or outside personnel are reminded of paying attention to the fact that the carbon dioxide concentration in the closed floating cabin exceeds the standard, and the rescue is immediately prepared.
3) The air inlet channel is communicated with the induced duct through the exhaust fan, the induced duct is arranged inside the sleeve, and the air outlet of the induced duct is close to the lower surface of the inner wall of the sleeve, so that the air inlet is directly communicated with the bottom inside the sleeve, the air inlet is prevented from passing through the upper surface of the sleeve and not reaching the bottom of the sleeve, and the new air is unevenly distributed in the sleeve.
4) The air outlet of the induced air duct is provided with a liquid level sensor, the liquid level sensor is connected with the emergency electric control cylinder through a controller, and after water in the sleeve is accumulated to a certain degree and blocks the air outlet of the induced air duct, the liquid sensor controls the emergency passage door to be opened through the controller.
Drawings
Fig. 1 is a schematic structural view of a closed floating bin with an emergency function.
Fig. 2 is a schematic diagram of the control of the closed floating bin with an emergency function.
As shown in the figure, the device comprises a sleeve 1, an annular inflatable ring 2, an emergency access door 3, an emergency electric control cylinder 4, an exhaust passage 5, an exhaust fan 6, a carbon dioxide concentration detector 7, a controller 8, an alarm 9, an induced draft tube 10 and a liquid level sensor 11.
Detailed Description
As shown in fig. 1 and 2, the closed floating cabin with the emergency function comprises a hollow sleeve 1 (two ends of the sleeve 1 are open), two annular inflation rings 2 are respectively arranged at two ends of the sleeve 1, two steel pipes of a pipe orifice need to be inserted into the sleeve 1 from two ends respectively during work, the two ends of the sleeve 1 are sealed after the annular inflation rings 2 are inflated, an emergency passage door 3 is arranged at the upper end of the sleeve 1, and the emergency passage door 3 is controlled by an emergency electric control cylinder 4;
The working principle is as follows: after the annular inflatable rings 2 at the two ends of the sleeve 1 are deflated, the sleeve 1 is hung into a construction foundation pit, one end of the sleeve 1 is sleeved on one steel pipe to be butted, the other end of the sleeve 1 is sleeved on the other steel pipe to be butted, then two steel pipes are butted in the sleeve 1 mechanically, a welder enters the sleeve 1 and welds the two steel pipes to be butted, after mud, stones and water are prevented from entering the sleeve in the welding process, the annular inflatable rings 2 at the two ends of the sleeve 1 are inflated to lock the steel pipes and simultaneously isolate water from entering the sleeve 1, an air inlet channel is communicated with an air guiding pipe 10 through an exhaust fan 6 in the welding process, the air guiding pipe 10 is provided with air sucked by the exhaust fan 6 and led into the lower surface in the sleeve, namely, the air is led to the bottom in the sleeve directly, the air inlet channel is discharged from an exhaust channel 5, a carbon dioxide concentration detector 7 detects the concentration of carbon dioxide in the sleeve 1 in real time in the exhaust process, if the concentration exceeds the standard, a controller 8 controls an electronic control emergency cylinder 4 to open an emergency channel door 3, and an alarm 9 starts to give an alarm.
