Brief description of the drawings
Fig. 1 is the profile of cooperation frock of the present utility model and object under test；
In all of the figs, identical reference is used for representing identical element or structure, wherein：
1- housings；2- objects to be tested；3- connectors；4-O type sealing rings；5- compressing members；6- hold-down bolts.
Embodiment
In order that the purpose of this utility model, technical scheme and advantage are more clearly understood, below in conjunction with accompanying drawing and implementation
Example, the utility model is further elaborated.It should be appreciated that specific embodiment described herein is only explaining
The utility model, it is not used to limit the utility model.
The utility model proposes a kind of cooperation frock for underwater installation voltage-withstand test, the cooperation frock includes：One
The housing 1 of end face opening, it is shaped as hemisphere, semiellipsoid, semicylinder, half round estrade, cylinder, round estrade, terrace with edge
Body or cuboid；Connector 3, is arranged at the circumference at the open end edge of housing 1, and extends to the outside of housing 1；It is more
Individual compressing member 5, the week of connector 3 is uniformly distributed in up and away from the housing 1.
The semicylinder, half round estrade are the half after cylinder, round estrade are splitted along shaft section respectively.
The housing 1 is hemisphere, semiellipsoid, semicylinder, half round estrade, the non-curved end face of the housing 1
Opening；Or the housing 1 is cylinder, round estrade, the bottom surface opening of the housing 1；Or the housing 1 is half terrace with edge
Body, prismoid or cuboid, the end face opening of the area maximum of the housing 1.
Illustrated below so that hemispherical treats voltage-withstand test object as an example.
As shown in figure 1, a kind of cooperation frock for underwater installation voltage-withstand test, including：It is shaped as hemispheroidal housing
1, the non-curved end face opening of the housing 1；Located at the open end edge of housing 1 circumference and extend to the housing 1
The connector 3 in outside；It is uniformly distributed in multiple compressing members 5 of the week up and away from the housing 1 of connector 3.In compressing member 5
On be also equipped with hold-down bolt 6, for hold-down bolt 6 through compressing member 5 and connector 3, wherein connector 3 is flange.
When carrying out voltage-withstand test using cooperation frock of the present utility model, shape is similarly hemispheroidal object under test 2
The outside of housing 1 is located at, makes housing 1 be connected to form closing space with object under test 2 by flange, in Fig. 1, two among bottom
Bar horizontal line is the contour line of flange inner surface.It is object under test 2 to be put into water in view of the requirement for carrying out voltage-withstand test,
The entirety that cooperation frock must then combined with object under test 2 makes a concerted effort to be zero suffered by water, i.e., buoyancy suffered by entirety is equal to weight
Power, meet following equation：
ρLiquidgVRow=mObjectg (1)
Wherein, ρLiquidRepresent environment liquid density, kg/m3；
VRowRepresent closing space, coordinate frock, three's volume sum of object under test, m3；
mObjectRepresent and coordinate frock and mass of object sum to be tested, kg；
G represents acceleration of gravity, m/s^2；
Above-mentioned formula is deformed：
Wherein housing 1 and the shape identical purpose of object under test 2 are to make on the premise of Whole power is zero, described in guarantee
Housing 1 is connected the closing space volume minimum formed with object under test 2, reduces the weight of counterweight most possibly.
In view of the hydraulic pressure and experimentation cost and experimental enviroment born in equipment investment water, object under test 2 is sub- gram
Power lucite material, it is 304 stainless steels to determine housing 1.Consider the influence such as hydraulic pressure, safety coefficient, service life
Factor, calculate the thickness for determining housing 1.Finally determined according to material density, spheroid volume calculation formula and above-mentioned formula (2)
The radius of hemispherical shell 1.
,, will in order to reduce cost because overall processing has certain difficulty during processing housing 1 with flange
Housing 1 and flange separate machined, then make housing 1 and flange welding integral with the mode of welding again.Simultaneously in view of welding
The influence of deformation, Analysis on Welding Deformation is carried out using simulation software, it is final to determine to thicken flange in welding region, simultaneously
Side welding edge carries out stress elimination so that welding deformation influences to be reduced to minimum.
After the completion of welding, O-ring seal 4 is set on flange, O-ring seal 4 is close to object under test 2 and flange,
So as to which the fluid ensured in environment cannot be introduced into closing space.According to applying working condition, O-ring seal 4 uses ethylene propylene diene rubber
Material, this material is cost-effective, can meet that sealing demand is simultaneously cheap.Finally, with compressing member 5 be compacted flange with
Object under test 1, hold-down bolt 6 is inserted into compressing member 5 with inside flange, cooperation frock is bonded with object under test 1 completely.
Complete above-mentioned steps, you can it is put into measuring targets in water and carries out underwater voltage-withstand test experiment, while without adding again
Fill counterweight.
It should be noted that the utility model proposes the cooperation frock for underwater installation voltage-withstand test can be various
Shape, reasonable selection, meet demand can be carried out according to the shape of object under test
As it will be easily appreciated by one skilled in the art that preferred embodiment of the present utility model is the foregoing is only, not
To limit the utility model, any modification of all made within spirit of the present utility model and principle, equivalent substitution and change
