Description
Technical field
The present invention relates to a kind of External floating roof tank floating plate static conductive state of earth wire on-Line Monitor Device.
Background technology
Large-scale crude oil tank farm determines once there is storage tank accident because of its storage medium and scale thereof, and its consequence is extremely serious.2010, point out in the article " ReducingtheCostofTankFarmandTerminalOperationsSafetyComp liancewhileIncreasingBusinessValue " that Snyder company delivers, major part oil company is improving management aspect, the improvement of POL depot management is often left in the basket, and most of fund is all put in the middle of refinery equipment, thus cause most of oil depot can only rely on manual site's operation, major part monitoring relies on artificial, information feed back has certain hysteresis quality, and human activity causes the rising of error risk, this has a significant impact the safety of oil depot and environmental protection tool.
Storage tank accident is still in generation in recent years, and oil company and security fields technician constantly sum up storage tank accident experience and lessons to prevent similar accident, and experience and lessons still cannot stop the generation again of accident.Annex on External floating roof tank floating plate all adopts static conductive ground wire to be connected with floating plate, once static conductive ground wire disconnects, these annexes probably become isolated conductor, and its electric discharge may be ignited the oil gas on floating plate, thus has an accident.These static conductive ground wires all carry out human at periodic intervals's inspection at present, and not only add workload, human activity too increases the probability of happening of accident.
Summary of the invention
The object of the present invention is to provide a kind of External floating roof tank floating plate static conductive state of earth wire on-Line Monitor Device, this device can be monitored automatically to the static conductive state of earth wire on External floating roof tank floating plate and annex, with the problem that the static conductive state of earth wire solved on current External floating roof tank floating plate and annex relies on human at periodic intervals to check for a long time, Timeliness coverage accident potential.
The technology used in the present invention solution is:
A kind of External floating roof tank floating plate static conductive state of earth wire on-Line Monitor Device, comprises photoresistance observation circuit and Double-layer flexible sleeve pipe; Photoresistance observation circuit comprises solar panel, photoresistance and hummer, and solar panel, photoresistance and hummer are connected to form closed-loop path by wire; Double-layer flexible sleeve pipe is arranged along static conductive ground wire, and fits tightly with static conductive ground wire, and Double-layer flexible sleeve pipe comprises outer layer sleeve and inner layer pipe, forms interlayer between outer layer sleeve and inner layer pipe, in interlayer, fill colored solutions; Described photoresistance is arranged in inner layer pipe, and outer layer sleeve and inner layer pipe are water white transparency pipeline.
Preferably, the two ends of described Double-layer flexible sleeve pipe are provided with fixing termination, and described solar panel and hummer are all arranged on fixing termination.
Preferably, described photoresistance observation circuit also comprises singlechip control panel, and singlechip control panel connects wireless transport module, and after the conducting of photoresistance observation circuit, singlechip control panel transmits signals to duty room by wireless transport module.
Preferably, the number of described photoresistance observation circuit arranges multiple.
Advantageous Effects of the present invention is:
The Double-layer flexible sleeve pipe that the present invention adopts has higher flexibility, can fit tightly with static conductive ground wire.Double-layer flexible sleeve pipe is water white transparency pipeline, and containing intermediate course gap, interlayer inner space fills colored solutions, once colored solutions flows out interlayer gap, sunlight can shine directly into pipe interior, after photoresistance is subject to sunlight irradiation, the conducting of photoresistance observation circuit, hummer is reported to the police.
Accompanying drawing explanation
Below in conjunction with accompanying drawing and embodiment, the invention will be further described:
Fig. 1 is External floating roof tank floating plate static conductive state of earth wire on-Line Monitor Device wiring layout of the present invention.
Fig. 2 is External floating roof tank floating plate static conductive state of earth wire on-Line Monitor Device exploded view of the present invention.
Fig. 3 is the sectional view of inner layer pipe in the present invention.
In figure: 1-fixes termination, 2-hummer, 3-solar panel, 4-outer layer sleeve, 5-inner layer pipe, 6-singlechip control panel, 7-photoresistance, 8-colored solutions, 9-wire.
Embodiment
By reference to the accompanying drawings, a kind of External floating roof tank floating plate static conductive state of earth wire on-Line Monitor Device, comprises photoresistance observation circuit and Double-layer flexible sleeve pipe.Photoresistance observation circuit comprises solar panel 3, photoresistance 7 and hummer 2, and solar panel 3, photoresistance 7 and hummer 2 are connected to form closed-loop path by wire 9.Double-layer flexible sleeve pipe is arranged along static conductive ground wire, and fits tightly with static conductive ground wire.Double-layer flexible sleeve pipe comprises outer layer sleeve 4 and inner layer pipe 5, forms interlayer between outer layer sleeve 4 and inner layer pipe 5, fills colored solutions 8 in interlayer.Photoresistance 7 is arranged at the inside center of inner layer pipe 5, and outer layer sleeve 4 and inner layer pipe 5 are water white transparency pipeline.The two ends of Double-layer flexible sleeve pipe are provided with fixing termination 1, and described solar panel 3 and hummer 2 are all arranged on fixing termination 1.
As to further improvement of the present invention, described photoresistance observation circuit also comprises singlechip control panel 6, and singlechip control panel 6 connects wireless transport module.After the conducting of photoresistance observation circuit, singlechip control panel 6 transmits signals to duty room by wireless transport module, thus operator on duty can be made to process in time, avoids having an accident.
Further, the number of described photoresistance observation circuit is set to two covers, adds the alarm reliability of monitoring device.
Installation of the present invention and use procedure are roughly as follows:
When static conductive ground wire is installed, the two ends of Double-layer flexible sleeve pipe in this device are connected with the two ends of static conductive ground wire respectively, the Double-layer flexible pipeline of centre and static conductive ground wire are sticked together, then static conductive ground wire is connected on floating plate annex and floating plate by fixing termination 1 respectively with this device.When static conductive ground wire ruptures, adhere to superincumbent Double-layer flexible pipeline also can rupture, and photoresistance observation circuit is owing to adopting armouring, its strength ratio Double-layer flexible pipeline is high, thus can not destroy, colored liquid now in Double-layer flexible pipe sandwich gap flows out because of the destruction of pipeline, thus sunlight can shine directly in inner photoresistance 7, thus make the conducting of photoresistance observation circuit, hummer 2 is reported to the police, duty room is transferred signals to by wireless transport module after singlechip control panel detects circuit turn-on simultaneously, thus can process in time, avoid having an accident.
