Description
Technical field
The present invention relates to a kind of derrick and the illuminating derrick anti-explosion LED of rig floor face light fixture with Yu Haiyang or land oil exploitation.
Background technology
The vapor-proof derrick light tool is the necessary product in the derrick of oil exploitation and the illumination of rig floor face.
On-the-spot actual demand situation: the illuminator with 9000 meters supporting rigs of drilling platforms is an example: the high 52M of derrick; The infield is outdoor; On-the-spot wind speed 36M/S (70knots), atmospheric temperature are-20 ℃～50 ℃; Humidity: in the time of+45 ℃, relative humidity≤95% ± 3%, trim rolling: 22.5o.The derrick geometry form is: turriform bottleneck formula, derrick body are that a cross section is that foursquare detachable, bolt is adorned closed steel construction, and quadruple board platform is above to be pyramidal structure; Use about 50 of the explosion-proof double tube fluorescent lamps of 2X40W approximately.That field requirement product integral body has is explosion-proof, shockproof, fire prevention, waterproof, anti-salt fog, performance such as anticorrosion, is adapted at that land or ocean are moist, moves under the salt mist environment condition, meets drilling platforms safety operation requirement.
The structure of on-the-spot existing explosion-proof lamp does; Bracket bottom end face and support base plate side welding (right angle welding), at the scene vibrations frequently, under the high situation of intensity; Being prone to produce weld bond snaps; Light fixture landing phenomenon only depends on a slight anti-decylization can not play very protection and does usefulness, is prone to cause near the operating personnel's of derrick personal injury.And the support of existing explosion-proof lamp is that fixed-direction uses, and unadjustable direction is installed complicated, time-consuming, effort.
The upper shell of existing explosion-proof lamp is more smaller than lower house, and lower house is provided with a circle groove, and upper shell crouches in the groove of lower house; Be embedded with a circle sealing strip in the groove; In last lower house extrusion process, the part of sealing strip can be exposed to the outside of housing, the corrosion of gases such as the salt that contains in 3-5 month wind and weather of process and the air, alkali, acid; Thereby make the sealing of lamp casing not strong, can not satisfy waterproof, anti-salt fog, on-the-spot environmental requirement such as anticorrosion.
The material of on-the-spot existing explosion-proof lamp is aluminium alloy, so product coat of paint large tracts of land obscission all occurs after using 3-5 month.
Existing every explosion-proof lamp is the conventional fluorescent lamps fluorescent tube, and light efficiency is low, light source service life short, waste a large amount of electric energy, and toxic element, contaminated environment such as the broken back of fluorescent tube is mercurous; Because of derrick high (52M); Use light fixture quantity many again (about 100 fluorescent tubes of the two-tube anti-explosion fluorescent lamp of 50 2X40W); And conventional fluorescent lamps fluorescent tube ubiquity, and anti-seismic performance is not strong, fluorescent tube is frangible; After every lamp failover is extinguished, all to climb up derrick and in time change, increase site operation personnel's the working strength and the danger of the person by the site operation personnel.
Summary of the invention
Deficiency in view of prior art exists the invention provides a kind of derrick anti-explosion LED light fixture.This light fixture adopts new light sources, scalable direction, sealing strong.
