Detailed description of the invention
Attached drawing is used to provide further understanding of the present invention, and is constituted part of this application, schematic reality of the invention
It applies example and its explanation is used to explain the present invention, do not constitute improper limitations of the present invention.In the accompanying drawings:
Fig. 1 is the structure principle chart for the device that embodiment detects watertight compartment system watertight state；
Fig. 2 is the schematic illustration that embodiment detects electronics cabin sealing system；
Fig. 3 is the schematic illustration that embodiment docks plug seal system detection；
Fig. 4 is schematic illustration of the embodiment to general assembly system detection.
Specific embodiment
The present invention will be further explained below with reference to the attached drawings.
The device of detection watertight compartment system watertight state as shown in Figure 1, has electronics cabin 1, connect with electronics cabin 1
Electrical system 8 and underwater electrical connector system 2, the gas nozzle 3 being connect with electronics cabin 1；The compressed gas gas being connect with gas nozzle 3
Source.Electronics cabin 1 has electronic compartment tank body 9 and electronics hatchway cover 10, and electronic compartment tank body 9 and electronics hatchway cover 10 pass through bolt 11
Connection is equipped with electronic compartment sealing ring 5, underwater electrical connector system 2 and electronics cabin between electronic compartment tank body 9 and electronics hatchway cover 10
It is equipped with connector seal ring 6 between 1, gas nozzle gasket 7 is equipped between gas nozzle 3 and electronics cabin 1.Electronic compartment sealing ring 5 patches
Part sealing ring 6, gas nozzle gasket 7 are used to guarantee the leakproofness of electronics cabin 1.When detection, compressed gas is passed through into electronic compartment,
Substep detection electronics cabin sealing pair, underwater electrical connector system sealing pair, the leakproofness of gas nozzle sealing pair and general assembly system；Scene
When state changes or leaks accidentally, then substep detection is carried out according to situation or general assembly detects.
The characteristic of each sealing subsystem are as follows: the sealing ring 5 of electronics cabin sealing pair is O-ring sealing, can be born inside and outside double
To pressure；The connector seal ring 6 of underwater electrical connector system sealing pair can only generally bear unidirectional external pressure or lower internal pressure；Gas
The gas nozzle gasket 7 of mouth sealing pair can bear inside and outside bidirection press.It is passed through compressed gas in electronics cabin 1, soaks electronics cabin 1
Enter in water, detected whether that bubble is emerged, with judge its whether good seal；The sealing detection of electronics cabin 1 mainly detects
The sealing reliability for the sealing pair that tank body 1 and electronic compartment sealing ring 5 are constituted.Due to electrical system 8, some components can only be held
When carrying the pressure of very little, therefore detecting, electrical system 8 is not filled.Since connector seal ring 6 can only bear lower internal pressure, so
When detecting, underwater electrical connector counter should fill, or replace underwater electrical connector with plug bolt pair 4.
As shown in Fig. 2, in the sealing system detection to electronic compartment tank body, the whole anti-dress or with plug spiral shell of underwater electrical connector
Bolt pair 4 is blocked.The electronics cabin 1 that assembly is sealed when detection immerses in water tank 12, is filled with from gas nozzle 3 into electronics cabin 1
Compressed gas makes electronics cabin 1 generate internal pressure, checks whether electronics cabin 1 has bubble to emerge: bubble-free, detection are qualified；There is company
Continuous bubble, then have leak source.Reason is analyzed according to leak source and is handled.
As shown in figure 3, all instead fill underwater electrical connector system 2 in the sealing system detection to electronic compartment tank body, it will
Electronics cabin 1 and underwater electrical connector system 2 immerse in water tank 12, are filled with the gas of 0.2 ~ 0.3Mpa into electronics cabin 1 from gas nozzle 3
Pressure, detected whether that bubble is emerged, with judge its whether good seal.2 sealing detection of underwater electrical connector system predominantly detects O-shaped
The sealing reliability of circle and core.Cable knob is inserted into water, checks nut junction, the outlet of underwater electrical connector system 2
Whether vulcanization port has bubble to emerge, bubble-free, and detection is qualified；There are continuous air bubbles, then have leak source, reason is analyzed simultaneously according to leak source
Processing, underwater electrical connector system 2 detect after qualification assembles that then hold mode no longer changes.
As shown in figure 3, being that the electronic compartment sealing ring 5 for checking electronics cabin 1 and gas nozzle 3 exist when to general assembly system detection
State changes the sealing reliability after general assembly.It is filled with the air pressure of 0.2 ~ 0.3Mpa into electronic compartment, checks 5 He of electronic compartment sealing ring
The sealing reliability of gas nozzle 3 because of its load performance mistake after tested, therefore need to only check its leakproofness after reassembling.
This detection method carries out watertight detection using watertight cabin system self structure, therefore in design, the phases such as design gas nozzle 3
Close functional interface.Watertight detection is carried out using self structure, large-scale and expensive hydraulic pressure kettle is needed not rely on, is detected with hydraulic pressure kettle
It compares, easy to operate, good manufacturability, high reliablity.
Compressed gas gas source needed for this detection method includes compressed air, compressed oxygen, compressed nitrogen.
For those skilled in the art, the invention may be variously modified and varied.It is all to be wanted in right of the present invention
Within the spirit and principle asked, any modification, equivalent replacement, improvement and so on should be included in protection scope of the present invention
Within.
