Description
Technical field
The utility model belongs to offshore boosting station platform lightning protection field, is applicable to the lightning Protection Design coordinating offshore boosting station platform helideck, is specifically related to a kind of novel lifting lightning rod being applicable to offshore boosting station platform.
Background technology
Offshore boosting station platform is based upon the even farther place of offshore tens kilometers, is the buildings that periphery is the highest, compares with land wind-powered electricity generation, and because sea more lacks protruding building, therefore, offshore boosting station platform is more easily struck by lightning.Therefore, lightning rod is widely used in the lightning Protection Design of offshore platform.
Marine damage to crops caused by thunder is much more serious than land, and offshore boosting station platform, as the hinge of Oversea wind power generation, must strict and thoughtful lightning Protection Design be carried out.And in order to satisfied construction, maintenance and the needs met in emergency circumstances, offshore boosting station platform must have helideck.According to the relevant regulations of " flying field, MH5013-2008 civil helicopter field technical standard ", helideck is different according to used helicopter kind, has strict restriction for the obstacle height around airplane parking area.The area of helideck is at 400m
2above, due to the limited area of offshore platform, be difficult to accomplish to arrange lightning rod outside the scope of regulation in Practical Project.And traditional terminal height is very high, is difficult to booster stations platform lightning Protection Design at sea and while requiring, meets again the design specification of helideck.
Visible, be applied in the lightning rod of offshore boosting station platform, must can either meet the needs of lightning protection, meet again the code requirement of helideck.Current lightning rod, height is certain, and the scope of protection is larger, and the height of lightning rod is higher, if be directly arranged in around helideck by traditional lightning rod, may bring potential safety hazard when helicopter landing.
CN201120285666.8 discloses the arrester device that a kind of Miniature wind electric field protects direct lightning strike completely, and aspect ratio rolling ball method calculates and has more 20% ~ 30%, effectively can be applied to the lightning protection of Miniature wind electric field.But offshore boosting station platform is larger, and this lightning rod cannot be elevated, and cannot solve helideck and to remove obstacles requirement and the contradiction of lightning protection requirement.
CN200920171412.6 discloses a kind of folding lightning rod, terminal height can be adjusted to a certain extent, but, adopt the limited height that folding lifting structure is elevated, and the undercapacity of accordion structure, be difficult to the environment of tackling offshore platform strong wind, the lightning protection measures of offshore boosting station platform can not be applied to.
In addition, be all about for convenience detach and prevent direct lightning strike about the patent of lightning rod mostly, shielding, and the function of not mentioned lightning rod lifting.
Utility model content
The utility model is just in order to overcome the shortcoming that above-mentioned existing lightning rod cannot be elevated flexibly; and devise a kind of novel lifting lightning rod being applicable to offshore boosting station platform; this lightning rod can effectively easily according to the height of actual conditions adjustment lightning rod; when being applied to offshore boosting station platform; the requirement of offshore platform lightning protection can either be met, the specification that helideck is removed obstacles can be met again.
The technical problems to be solved in the utility model is, for different helicopters, has different Clearance requirements to the airplane parking area that it uses.Such as tandem rotors helicopter airplane parking area regulation; in barrier sector region, barrier must not higher than 1.1m, and single rotor and laterally disposed dual rotor type helicopter airplane parking area regulation; in barrier sector region, barrier can not higher than captain's 0.05 times.
For solving the problems of the technologies described above, the utility model adopts following technical scheme:
Be applicable to a novel lifting lightning rod for offshore boosting station platform, comprise lightning rod body (1), lifting structure; Lifting structure comprises base (6), three grades of stretching structures, and three grades of stretching structures comprise the first order support bar (3), second level support bar (4), the third level support bar (5) that connect successively from the bottom to top; Lightning rod body (1) is fixed on the top of third level support bar (5), and first order support bar (3) is fixed on base (6), and base (6) fixes on the ground.
Also include supporting bracket (2); Described first order support bar (3) is provided with retainer ring (7), one end of supporting bracket (2) is connected with retainer ring (7), the other end is connected with the pad (8) being fixed on ground, and supporting bracket (2), ground, first order support bar (3) form triangular structure.
Described base (6) is provided with ground interface (9), lightning rod body (1) is connected with the ground interface (9) on base (6) by being placed in the wire of the support bar inside at different levels in three grades of stretching structures, and is connected with building earth mat by ground interface (9).
The length of described first order support bar (3) is lightning rod shortest length, and connection, the third level support bar (5) of described base (6) and first order support bar all adopt rotating helical structure with the connection of lightning rod body (1).
Know-why of the present utility model: according to the lightning Protection Design requirement of offshore boosting station platform, determine the maximum height H of arranged lightning rod, and the particular location that lightning rod is arranged; According to the helicopter kind using offshore platform helideck, determine the minimum altitude h of arranged lightning rod.The length of the every one-level of lightning rod telescopic supporting rod is determined according to H and h, buckle is arranged at the top of every one-level telescopic supporting rod, hole clipping is arranged at bottom, the flexible and fixing of every one-level telescopic supporting rod is completed by such form, by being connected to the retainer ring of afterbody expansion link, supporting bracket is firmly connected with lightning rod, prevents because the lightning rod that strong wind causes rocks.Finally each assembling parts is got up to form the lightning rod that can be applied to offshore boosting station platform.
When this lightning rod is arranged on offshore boosting station platform, at ordinary times based on lightning protection effect, require lightning rod to be elevated to higher position according to Practical Project.When because construction, when maintenance or the needing of emergency, by regulating the support bars at different levels of lightning rod, lightning rod is dropped to the height meeting helicopter landing requirement.By the time after helicopter leaves offshore platform, more again lightning rod is returned to original height.
Compared with prior art, the utility model can according to the height of the Clearance requirement adjustment lightning rod of helideck, and flexibility is high, practical.
