Description
Technical field
Compressed-air energy storage facility the invention belongs to be used for storage station, specifically related to one kind can enter for storage station
Row defects detection, the zawn gas storage library structure of monitoring.
Background technology
Underground natural gas storage tank compressed air energy storage station is mainly cooperation wind energy, tide energy and HYDROELECTRIC ENERGY, electricity in power network
There is underground natural gas storage tank in the potential energy that unnecessary electric energy during power load low ebb changes into compressed air, in the release of peak of power consumption period
Generated electricity by compressed air, play a part of " battery ", there is peak load shifting, optimization power network and emergency use to make in power system
With.
This seminar proposes to carry out high-pressure gas seal using zawn first, and its structure is on the basis of naked hole is excavated
Successively sealed with just lining concrete layer, waterproof layer, two lining concrete layers and glass-reinforced plastic material.Fiberglass is due to certain
Intensity, rigidity, deformability and cheap, are the cost performance highest materials that can be applied to underground natural gas storage tank sealing at present.
But there is problems with pure fiberglass sealed material sealing zawn gas storage：
1）How is fiberglass construction effect, if there is the defects such as microfissure, hole, it is impossible to by the Site Detection hand such as electric spark
Section detection.
2）During gas storage inflation/deflation, how is the sealing effectiveness of fiberglass, if there is the phenomenons such as gas leakage, it is impossible to enter
Row real-time monitoring.
The content of the invention
Regarding to the issue above, the present invention is intended to provide defect is detected a kind of convenience and the glass-reinforced plastic material monitored is close
The zawn gas storage library structure of envelope.
The technical scheme of solve problem of the present invention is：It is a kind of to carry out defects detection, the zawn gas storage knot of monitoring
Structure, is included in the air storing cavity of subterranean body cutting, and the air storing cavity includes just lining concrete layer, waterproof layer, two linings from outside to inside
Concrete layer, carbon fiber layer, fiberglass sealed layer；
Distributed optical fiber sensing system is provided between the two lining concrete layer and carbon fiber layer；
To being equipped with hermatic door, the hermatic door is fixed on subterranean body for one end of the air storing cavity, and hermatic door is provided with and gas storage
The filling channel and bleed passage of chamber connection；
Hermatic door is sealed with the joint of air storing cavity.
In such scheme, using the electric conductivity of carbon fiber layer, can be using the fine fisssure in electric spark detection fiberglass sealed layer
Seam and defect, so as to detect the air-tightness of fiberglass sealed layer.
Under conduction of heat, during gas storage inflation/deflation, between two lining concrete layers and fiberglass sealed layer everywhere
Temperature reaches unanimity, and using distribution type fiber-optic to the sensitiveness of temperature, can monitor temperature change everywhere, occurrence temperature mutation
Place is then likely to occur fiberglass gas leakage, realizes real-time monitoring.
Further, the optical fiber of the distributed optical fiber sensing system axially, two is served as a contrast in concrete layers along air storing cavity
Spiral winding arrangement on wall.
Further, the two ends of the air storing cavity are the sphere for seamlessly transitting.
In such scheme, two ends are using the purpose of sphere, can be smoothed with end joining place in air storing cavity chamber body
Cross, be not in mutation, fiberglass sealed material can be avoided to occur being come off caused by stress concentration.
The hermatic door is cirque structure, and its front end closing, rear end open, front end is provided with installation filling channel and deflation
The groove of passage, open end is docked with air storing cavity one end；
Hermatic door is fixed by axially fastening bolt and ring fastening bolt with rock mass.
Preferably, the hermatic door passes through rubber seal with the joint of air storing cavity.
Further, fiberglass sealed layer is made up of field-applied.Scene directly makes sealant, will not produce and connect
Seam.
Remarkable result of the invention is：
1. setting carbon fiber layer can easily carry out spark test, to check defect, crack in fiberglass sealed layer,
Construction effect to fiberglass makes evaluation, excludes risk, improves security.Carbon fiber layer also has thickness small simultaneously, volume
It is small, small, the advantage of easy construction of conducting oneself with dignity.
2. setting distributed optical fiber sensing system can continuously be sensed in very big spatial dimension, certainty of measurement
Can determine that within 0.5 meter.There is simple structure simultaneously, easy to use, cost performance advantage high.
In a word, to add carbon fiber layer and distributed optical fiber sensing system to reach in gas storage library structure close to fiberglass
The envelope effect purpose that is detected respectively and monitored, and there is simple structure, easy construction, cheap, with good
Good application value.
