The insulating oil in face, the method for transporting transformer under no oil condition, but transport the transformer without oil, it is easy to cause absolutely
Edge dampness, so traditional oil-free transport requires to fill nitrogen, dry air or other inert gases in transformer, to subtract
A possibility that few humidified insulation, therefore, the inside transformer air pressure after inflation remains between 0.01-0.05MPa, to reach
To safe and reliable, and this also requires to install impact record instrument inside it to be also able to bear bring pressure after inflation,
The electronic type impact record instrument of especially present mainstream, electronic device is more sensitive to pressure, therefore installs electronic type impact note
It needs to carry out electronic type impact record instrument pressure test before record instrument, passes through pressure vessel testing electronic type impact record instrument at present
Pressure resistance during, it is also necessary to it is synchronous to carry out vibration-testing, to imitate true transportational process, still, currently used for test
Pressure vessel sealing cover be all mostly it is flanged, fit sealing is carried out by screw or bolt, pressure vessel by plus
After pressure, in the vibration processes of the frequency conversion acceleration of shake table, screw or bolt easily loosen, and cause stress the close of container
Envelope failure, influences the accuracy rate of pressure test, loses the meaning of pressure test.
Summary of the invention
To solve the deficiencies in the prior art, the present invention provides a kind of anti-loosening sealing cover of pressure vessel, and structure is simple, behaviour
Facilitate, loosen the sealing cover of pressure vessel will not because the frequency conversion acceleration of shake table vibrates, ensure that and be placed on
Test effect of electronic type impact record instrument during the synchronous pressure test carried out and vibration-testing inside pressure vessel,
Improve the pressure test and vibration-testing accuracy rate of electronic type impact record instrument.
The technical scheme adopted by the invention is as follows：
A kind of anti-loosening sealing cover of pressure vessel, the sealing including pressure vessel ontology and sealed pressure vessel ontology
It covers, is formed with multiple equally distributed screw holes, the opening of the pressure vessel ontology on the circumferencial direction of the sealing cover
It is formed with threaded hole corresponding with multiple equally distributed screw holes, the sealing cover is screwed by fixing piece across screw hole
It is fastenedly connected in threaded hole with pressure vessel ontology, the fixing piece includes threaded rod and locating rod, and the threaded rod passes through close
Screw hole in capping is screwed into the threaded hole on pressure vessel ontology, the threaded rod and locating rod rotation connection, described close
Locating slot corresponding with locating rod is provided on capping outer surface, the locating rod rotation is fastened in locating slot.
Further, in order to improve the rotation flexibility of locating rod and threaded rod, the threaded rod and locating rod are hinged.
Further, the locating rod being fastened in locating slot in order to prevent is influenced by external force and pops up locating slot, the positioning
Bar is connected with locating slot magnetic absorption.
Further, the thickness of the locating rod be equal to locating slot depth, ensure that sealing exterior surface aesthetics and
Consistency.
Further, in order to improve the contact area of locating rod and locating slot, so that locating rod is preferably played positioning and make
With the section of the locating rod and locating slot is T shape.
Further, it is provided with the arc slot communicated with locating slot on the sealing exterior surface, conveniently opens and is fastened on positioning
Locating rod in slot.
Further, card slot is formed in the locating slot in locating rod corresponding with the arc slot, raising opens button
That closes the locating rod in locating slot opens efficiency.
Further, knob is provided on the sealing exterior surface, it is convenient that sealing is lifted during installation and removal
Lid.
The beneficial effects of the present invention are：The screw hole that threaded rod passes through on sealing cover is screwed into the spiral shell on pressure vessel ontology
It can be rotated in the locating slot being fastened on sealing cover in pit with locating rod that threaded rod is hinged, the screw thread after preventing fastening
Bar loosens, and structure is simple, easy to operate, makes the sealing cover of pressure vessel will not be due to the frequency conversion acceleration of shake table vibrates
It loosens, ensure that the electronic type impact record instrument being placed on inside pressure vessel in the synchronous pressure test and vibration carried out
Test effect in test process improves the pressure test and vibration-testing accuracy rate of electronic type impact record instrument.
