Description
Technical field
The present invention relates to LNG storage tank internal monitoring device, more specifically, relate to one and improve the internal prison of LNG storage tank
The structure of view apparatus, improves safety, moving up and down and rotating and easily carry out tank inside by means of monitoring arrangement
Supervision, thus improve monitor performance LNG storage tank internal monitoring device.
Background technology
The LNG storage tank used for keeping or conveying LNG, only keeps with extremely low temperature (about-163 DEG C) liquid
The temperature changed just will not form gasification, keeps the state of liquefaction, thus is provided with cooling facility.
If described LNG storage tank temperature rises, then gassing gasifying, thus volumetric expansion so that blast
Dangerous increase, so that persistently monitor.
But, keep extremely low temperature state, therefore, if photographic head is installed on inside, then owing to LNG storage tank is internal
Due to extreme variations in temperature, the life-span of photographic head can be shortened or be likely damaged.
It addition, for monitoring the photographic head within LNG storage tank, in the installation carrying out the device tilting and moving up and down
Time, operate at inner utilization electric power, thus sparklet can occur inside LNG storage tank.This sparklet is in pole
LNG storage tank inside and the gas reaction gasified along with variations in temperature of low temperature state, can make the dangerous increase of blast.
Particularly when flashing, if contacted with oxygen, then there is combustion phenomena, the danger of blast can be made to increase the weight of,
Thus should use and there is the photographic head that oxygen inflow can be made to realize minimizing the explosion prevention function that maybe can bear blast, thus
Expense can increase.
It addition, the photographic head within supervision LNG storage tank, the cold air of extremely low temperature will be exposed in the inside of LNG storage tank,
Temperature drastically changes due to the presence or absence along with the LNG stored in LNG storage tank, thus the intrusion of cold air and temperature drastically
Degree changes and photographic head can be produced impact so that it is damage extremely cannot operating condition.
And, supervision photographic head within LNG storage tank is inside LNG storage tank, and surface tension is lower than water, thus cruelly
Under the state being exposed to LNG gas, if implementing the inclination operating moving up and down and carrying out to rotate, then send out in obliquity
Raw friction, by means of friction so that the LNG gas that surface tension is lower than water forms attachment, and operating interference occurs,
Thus be difficult to accurately operate, the machinery at photographic head can damage.
Therefore, a kind of LNG storage tank internal monitoring device of an urgent demand exploitation, in the extremely low temperature within isolation LNG storage tank
Under the state of cold air, by means of moving up and down and rotating, LNG storage tank can be monitored, it is possible to contact preventing oxygen
Keep the temperature of photographic head simultaneously.
Summary of the invention
Solve the technical problem that
The present invention is precisely in order to improve described problem and invent, and the problem that the invention solves the problems that is to provide a kind of LNG storage
Tank internal monitoring device, installs photographic head, to monitor inside LNG storage tank, and by implement the moving up and down of photographic head,
The driving means of rotation and inclination movement is installed on the outside of LNG storage tank, thus improves supervision efficiency, gives holding and takes the photograph
As head temperature and explosion prevention function, thus improve safety.
