The skeleton comprises an outer ring frame, a radial beam, a center disk, and a cylinder-shaped float. The utility model has the advantages of simple structure, reliable performance, energy saving, reduced pollution, etc. Besides, the utility model can prevent or reduce the evaporation loss of petroleum. The utility model is used for the storage and the transportation of petroleum.
Description
The utility model is a kind of device that belongs to energy-conservation and reduce environmental pollution, and it is assembled among the petroleum storage tank, is used to prevent or reduce the evaporation loss of petroleum products.
Up to now, the skeleton that is adopted in the tradition petroleum storage tank floating plate mainly comprises two kinds of structures, a kind of is by float and L (or the gridiron skeleton of [) type aluminium formation, its feature is the combination of being convenient between top board and the skeleton, weak point just is that integral rigidity is poor, and causes the stable not ideal enough of floating plate.The radiation-like skeleton that another kind is made up of radially float beam and dowel, though it has overcome the defective of gridiron skeleton integral rigidity difference, but bring inconvenience for the combination between skeleton and the top board, for example, when adopting rivet combination between skeleton and the top board, adjacent two rivet spacinges do not wait, and are not excessive, be exactly too small, cause linking intensity not ideal enough etc.
The purpose of this utility model is that a kind of improved petroleum storage tank compound type floating plate will be provided, and makes floating plate have enough rigidity and stability, again can actv. be convenient to the combination between skeleton and the top board, guarantees enough linking intensity and cost-cutting.
The purpose of this utility model is achieved in that a kind of petroleum storage tank compound type floating plate, it mainly comprises grommet type seals, top board, the static let-off gear(stand), automatic connection for bbreather pipe, anti-rotation device, pillar, spider and skeleton parts such as (H), top board is a garden disk body of being made by metallic material, be assembled in above the skeleton by fastener, and outside garden week top, be assembled with grommet type seals, the jar end of one end of anti-rotation device and storage tank, link, the other end is the pilot hole that passes top board, tank deck with storage tank fixes again, the two ends of static let-off gear(stand) connect with the tank deck of top board and storage tank respectively, automatically connection for bbreather pipe is by fastener and top board combination, among skeleton, be assembled with pillar, it is characterized in that said skeleton, mainly by the outer shroud frame, radial girders, compositions such as spider and tubular float, between adjacent two radial girders, be assembled with some, the tubular float that axis is parallel to each other, its included angle B
1=(180 °-B
2)/2, B
1＜90 °, radial girders is that the center-point with spider is that the garden heart is radiation-like and arranges, forms an integral structure by fastener and outer shroud frame and spider.It comprises monomer and two kinds of structures of complex the tubular float, and complex structure is the surface at shell, the position that is parallel to each other with tubular float axis, is assembled with the top board dowel.
The utility model is compared with traditional floating plate, has tangible good effect:
A. because radial girders is a center-point with spider is that the garden heart is radiation-like and arranges, compare, have enough rigidity and stability with the gridiron skeleton;
B. again owing between adjacent two radial girders, be assembled with the tubular float that some, axis are parallel to each other, it is compared with the skeleton that float is the radiation-like layout, can save material, cost-cutting by actv., be more convenient for combination between skeleton and the top board, can make the spacing equalization between the rivet, stressed even, guarantee to have enough linking intensities;
C. because on the shell of tubular float, combination has the top board dowel, and it can increase the rigidity of tubular float, can make the top board dowel have the small construction size again, reach the purpose of saving material, cost-cutting.
Concrete structure of the present utility model is provided by following embodiment and accompanying drawing thereof.

Describe in detail according to concrete device and the service condition that the utility model proposes below in conjunction with Fig. 1, Fig. 2.This floating plate comprises grommet type seals (1), top board (2), static let-off gear(stand) (4), automatic connection for bbreather pipe (5), anti-rotation device (6), pillar (9), spider (14) and skeleton (H).Skeleton (H) is made up of outer shroud frame (3), radial girders (12), spider (14) and tubular float (13) etc., is assembled with the tubular float (13) that some, axis are parallel to each other between adjacent two radial girders (12), its included angle B
1=(180 °-B
2)/2, B
1＜90 °, B
2=360 °/n (n: the radical of radial girders 12), radial girders (12) is that the center-point with spider (14) is that the garden heart (that is axis 11) is radiation-like and arranges, by fastener (for example bolt, Connection Card) and outer shroud frame (3), tubular float (13) and spider (14) composition one integral structure; On skeleton (H), by rivet or screw retention top board (2) is arranged, top board (2) is a garden disk body, by the grommet type seals (1) that oil resisting material is made, is by being bolted to the top of outer garden week of top board (2); The pillar (9) that is made of metal tube is to be assembled among the skeleton (H); By the anti-rotation device (6) that steel rope (or steel pipe) constitutes, the jar end of its end and storage tank (7), link, the other end is the pilot hole that passes top board (2), fixes with the tank deck of storage tank (7) again; Static let-off gear(stand) (4) is made up of the multiple twisted wire of some soft coppers, the two ends of the every multiple twisted wire of soft copper, connect with the tank deck and the top board (2) of storage tank (7) respectively, automatically connection for bbreather pipe (5) by fastener (for example bolt or rivet) be assembled in top board (2) above.
Combination by said structure, liquid level (8) in storage tank (7) rises to and tubular float (13) when contacting, make tubular float (13) produce a buoyancy F, buoyancy F is greater than the deadweight (comprising the friction force that floating plate produces) of floating plate, because the effect of buoyancy F, make floating plate along anti-rotation device (6), move along with the lifting of liquid level (8), because liquid level (8) is blocked by top board (2) and grommet type seals (1), thereby avoid or reduced the evaporation loss of pasta (8), when floating plate with liquid level (8) when dropping to extreme lower position, the deadweight of its floating plate is all born by pillar (9), at this moment automatic connection for bbreather pipe (5), under the effect of valve rod own, self-opening is to the desired location.
