Detailed description of the invention
Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is explained.
Embodiment one
As shown in Figure 1, square cell body 2, honeycomb core 5, groove lid 1, sealed fixing device 3 is comprised for the grooved buoyancy aid of inner floating roof in the utility model embodiment.
Honeycomb core 5 is aluminum honeycomb core, and oil resistant is lost, good seal performance.Honeycomb core 5 is fixedly bonded in square cell body 2.
Square cell body 2 is square structure, the complete opening in top and two ends.The height of honeycomb core 5 is less than the height of square cell body 2.
The cross-sectional plane of groove lid 1 is right-angled U, and shape is identical with the shape of square cell body 2, and the length of groove lid 1 is greater than the length of square cell body 2.Groove lid 1 is positioned at square cell body 2, is bonded in the upper surface of honeycomb core 5.Groove lid 1 is not only easy for installation, and is convenient to trample on grooved buoyancy aid when staff overhauls.
The sections transverse face of groove lid 1 right-angle surface and square cell body 2 is superimposed, is alongst filled with sealed fixing device 3 between lamination portion, and the sealed fixing device 3 in this embodiment is injecting glue.Injecting glue plays effect that is fixing, sealing, not only makes between groove lid 1 with square cell body 2 together with strong bond, can also prevent oil gas from revealing simultaneously.In addition, between lamination portion, be not only provided with injecting glue, but also make both be fixed together by bolt (not shown).
When using grooved buoyancy aid, the open end of square cell body 2 is called the open end of grooved buoyancy aid, and two sides of square cell body 2 are called the sealing surface of grooved buoyancy aid.
Due to the complete opening in two ends of square cell body 2, therefore honeycomb core 5 contacts completely with medium, because aluminium honeycomb core 5 is filled with having living space of cell body 2, and aluminium honeycomb core 5 tightly glueds joint with cell body 2 and groove lid 1, medium is intercepted by aluminium honeycomb core cannot penetrate into square cell body 2, ensure that the leak tightness of whole grooved buoyancy aid, fundamentally stop the possibility of heavy dish.
In addition, be fixedly connected with by bolt 4 between two grooved buoyancy aids that sealing surface is adjacent, and be provided with sealing joint strip 6 between adjacent two sealing surfaces, as shown in Figure 4, the groove lid 1 of side grooved buoyancy aid, the lamination portion of cell body 2 are fixedly connected with by bolt 4 with the groove lid 1 of opposite side grooved buoyancy aid, the lamination portion of cell body 2, and are provided with sealing joint strip 6 between abutting closure face.Such design can not only strengthen the sealing property between grooved buoyancy aid, prevents oil and gas loss, also can combine between adjacent two grooved buoyancy aids securely simultaneously, improve the intensity of whole floating plate, is also convenient to install and maintenance simultaneously.
Because the cellular board-like inner floating roof of immersion type is in operational process, immerse below medium liquid level 2-3cm, there is not oil-gas space, medium volatilizees nowhere, reduces the volatilizing loss of medium, ensure that safety.
Embodiment two
As shown in Figure 2, the difference of the present embodiment and embodiment one is the shape of groove lid 1 and the position of sealed fixing device 3.
The present embodiment middle slot lid 1 is dull and stereotyped.Groove lid 1 is alongst provided with sealed fixing device 3 with the junction of square cell body 2.Sealed fixing device 3 in the present embodiment adopts injecting glue, and injecting glue can not only prevent oil gas from revealing, but also groove lid 1 and square cell body 2 is closely fixed together.Staff's installation and maintenance are not only convenient in the structure of groove lid 1 and sealed fixing device 3 and annexation design, and can prevent oil gas from revealing, and improve the quality of grooved buoyancy aid, thus improve the quality of whole floating plate.
Embodiment three
As shown in Figure 3, the present embodiment is the different of sealed fixing device 3 from the difference of embodiment two.
The present embodiment middle slot lid 1 is dull and stereotyped, form right angle between groove lid 1 and square cell body 1.
Be provided with sealed fixing device 3 along groove lid 1 and square cell body 1 junction, sealing anchor fitting 3 is angle block of right angle.The right angle of angle block of right angle and the right angle formed between groove lid 1 and square cell body 2 closely superimposed.Be fixed together by bolt (not shown) between angle block of right angle and square cell body 1.Adopt angle block of right angle as sealed fixing device, can sealing property be strengthened, prevent oil gas from revealing, simultaneously angle block of right angle manufacture, installation, convenient disassembly, be convenient to safeguard, be applicable to actual use.
Above embodiment of the present utility model has been described in detail, but described content being only preferred embodiment of the present utility model, can not being considered to for limiting practical range of the present utility model.All equalizations done according to the utility model application range change and improve, and all should still belong within patent covering scope of the present utility model.
