Fig. 2 is an assembly diagram (i) of the present invention.
Fig. 3 is a schematic assembly diagram (ii) of the present invention.
Fig. 4 is a third assembly diagram of the present invention.
As shown in the figure, the device comprises a right sealed cabin 1, a left sealed cabin 2, an expansion joint 3, a sealed head 4, a fixed steel ring 41, a fastening chain 42, a rubber sealing ring 43, an exhaust fan 51 and a carbon dioxide concentration detector 52.
Detailed Description
As shown in fig. 1, a combined closed floating bin structure comprises a right sealed bin 1 and a left sealed bin 2 with two open ends, wherein the right sealed bin 1 is connected with the left sealed bin 2 through an expansion joint 3, and the expansion joint 3 is preferably a water-proof plastic casing;
the non-connecting end of the right sealed cabin 1 and the left sealed cabin 2 is respectively provided with a sealed head 4, preferably, the sealed head 4 comprises a fixed steel ring 41 and a rubber sealing ring 43 arranged on the inner surface of the fixed steel ring 41, the outer surface of the rubber sealing ring 43 is provided with a fastening chain 42,
the fixed steel ring 41 is tightly attached to the inner wall of the right sealed cabin or the inner wall of the left sealed cabin, the surface of one end of the pipe is wrapped by the rubber sealing ring 43 when the pipe is used, and then the rubber sealing ring 43 is tightly pressed on the outer surface of one end of the pipe after being adjusted by the fastening chain 42, so that the water seepage amount of a contact sealing surface is less than 0.018L/h;
the fixed steel ring 41 is tightly attached to the inner wall of the right sealed cabin 1 or the inner wall of the left sealed cabin 2;
a ventilation component is arranged on the right sealed cabin 1 and/or the left sealed cabin 2;
the ventilation component comprises an exhaust fan 51 arranged in the right sealed cabin 1 and the left sealed cabin 2, if the volume of the right sealed cabin 1 and the left sealed cabin 2 is small, the ventilation component can be arranged in the right sealed cabin 1 or the left sealed cabin 2, if the volume of the right sealed cabin 1 and the left sealed cabin 2 is large, the ventilation component can be respectively arranged in the right sealed cabin 1 and the left sealed cabin 2, the exhaust fan extracts air in the right sealed cabin 1 and the left sealed cabin 2, new air enters the ventilation component, and therefore harmful gas components in the right sealed cabin 1 and the left sealed cabin 2 are reduced, the ventilation component further comprises a carbon dioxide concentration detector 52 arranged in the right sealed cabin 1 and/or the left sealed cabin 2, the carbon dioxide concentration detector 52 is connected with the exhaust fan 51, and when the carbon dioxide concentration detector 52 detects that the carbon dioxide concentration in the right sealed cabin 1 and/or the left sealed cabin 2 exceeds a preset value, the exhaust fan 51 is started immediately to extract harmful gas in the right sealed cabin 1 and the left sealed cabin 2.
