Abstract
The utility model discloses an earth surface overflow drainage cover for a buried natural gas pipeline, and belongs to the technical field of oil-gas storage and transportation as well as safe operation. A middle gas guide spliced plate consists of a V-shaped funnel cover, a sled type middle main plate, rotating shaft sleeves, pre-assembled hinge shafts and auxiliary tongs; the V-shaped funnel cover is provided with a hollow funnel cavity; the upper part of the V-shaped funnel cover is sleeved with an air distribution and gas guide pipe; the lower part of the V-shaped funnel cover is integrally welded with the sled type middle main plate; two ends of the sled type middle main plate are provided with curled arc warpings; a hole in the middle part of the sled type middle main plate is matched with the lower end of the V-shaped funnel cover; the rotating shaft sleeves and the pre-assembled hinge shafts are combined to form six sets which are uniformly arranged on two sides of the middle gas guide spliced plate; the auxiliary tongs are welded to the middle parts of two ends of the middle gas guide spliced plate. When the buried natural gas pipeline leaks gas, the drainage cover device is arranged at an earth surface overflow position in time, so that damage, caused by overflowing gas due to a fact that the conventional pipeline cannot stop transportation and reduce the pressure in time, to the surrounding environment, entering of rescue personnel and rescue equipment, digging work and the like is avoided.
Description
Technical field
The utility model relates to the excessive drainage hood in a kind of buried natural gas line earth's surface, belongs to Oil & Gas Storage safe operation technical field.
Background technique
The buried natural gas line leaking as early as possible stopping transportation step-down is very necessary for repairing, so just can not cause leakage point earth's surface rock gas to fill the air in a large number, and surrounding environment is marched into the arena and brought potential safety hazard with the personnel of speedily carrying out rescue work.And, only have exposed pipeline to be just convenient to rush to repair operation, make the natural gas line of buried leakage expose earth's surface, all very large of the Security of excavation, complexity.But reality is but due to every aspect, if occur suddenly to leak to destroy at the pipeline of operation, be difficult to stopping transportation step-down at once, this just makes near rock gas harm leakage point sharply raise.If can, by the rock gas carrying-off isolation of this part leakage, will put earth's surface environment around to pipe leakage so, and follow-up repairing excavation, personnel are frequent etc. that very large support is provided.Therefore, researching and developing excessive drainage system for the buried natural gas line leaking, to reaching most leakage rock gas carrying-offs, create necessary condition for pipe leakage accident treatment, is a problem that is worth further investigation.
Summary of the invention
In order to overcome the deficiencies in the prior art, the utility model provides a kind of buried natural gas line earth's surface excessive drainage hood, while solving buried natural gas line generation leakage, how by see through the inflammable gass such as the excessive methane in earth's surface of buried soil layer as early as possible drainage walk the problem so that digging in-situ, repair personnel are marched into the arena etc. fast.
The excessive drainage hood in a kind of buried natural gas line earth's surface, middle bleed jigsaw is made up of mainboard, rotating shaft cover, prepackage hinging shaft and auxiliary handgrip in V-type funnel cover, Sledge type; V-type funnel cover band hollow funnel chamber, V-type funnel cover top socket cloth wind air entraining pipe, in V-type funnel cover bottom and Sledge type, mainboard is welded; In Sledge type, there is the arc warpage twisting at mainboard two ends, and in Sledge type, mainboard middle part hole and V-type funnel cover lower end match; Rotating shaft cover is combined into six covers with prepackage hinging shaft and is evenly arranged in middle bleed jigsaw both sides; Middle part, bleed jigsaw two ends in the middle of auxiliary handgrip is welded in; Left and right expansion jigsaw is made up of left and right wing plate and rotating shaft cover; Left and right wing plate profile is band major axis semiellipse and long rectangle combination; Rotating shaft cover is corresponding with the rotating shaft cover dislocation on middle bleed jigsaw, is fixedly welded on the long straight flange of left and right wing plate; Under cloth wind air entraining pipe, be terminated at the osculum end of V-type funnel cover; Cloth wind air entraining pipe communicates with leaking analog channel, leaks analog channel and communicates with buried natural gas line.
A using method for the excessive drainage hood in buried natural gas line earth's surface, contains following steps;
First cloth wind air entraining pipe is raised to high-altitude by assistance for lifting lever arrangement, makes air entraining pipe produce atm difference up and down and there is nature suction; Pull lid and be pressed onto excessive gas top being hinged to overall bleed jigsaw and left and right expansion jigsaw again, under the excessive pressure of excessive gas itself and the draught head acting in conjunction of the different generations of the upper and lower rarefaction of air degree of air entraining pipe, realize the excessive inflammable gas of the carrying-off earth's surface overwhelming majority; Simultaneously by manually earthing compacting suitably being done in jigsaw top.
Excessive like this gas, by the excessive pressure of itself and the suction of air entraining pipe, has just been directed into high-altitude, has reduced near the combustable gas concentration in earth's surface, has realized drainage target, for condition has been created in follow-up processing.
The beneficial effects of the utility model are: when buried natural gas line occurs to leak, by timely drainage hood device being covered in to excessive place, earth's surface, solve the harm that excessive gas that pipeline stopping transportation step-down in time produces is marched into the arena to surrounding environment, the personnel equipment of speedily carrying out rescue work and excavated operation etc.The application of the excessive drainage hood in earth's surface, the response efficiency by riser tubing operation maintenance business scope to accident, is the important supplementary equipment of pipe first-aid accident treatment, therefore, the excessive drainage hood in buried rock gas earth's surface will have good application prospect.
