The position of latch 41 is adjusted, especially after sampling, enables to locking by pulling downward on gripping block 44
Block 41 retracts inside the first cavity 11, so that the lock state of driving mechanism releases, facilitates using driving mechanism to piston mechanism
Extension elongation be adjusted.
As shown in figure 9, sealing unit 33 includes sealing ring for the cut-away illustration of sealing unit 33 described in the present apparatus
331 and pedestal 332.The sealing ring 331 is arranged on the top surface of pedestal 332, for realizing between the present apparatus and sampling valve 7
Sealing is equipped with the connecting hole 3322 being connected with oil guiding hole 322 on pedestal 332, can be led insulating oil by connecting hole 3322
To the inside of oil guiding hole 322.Specifically, after sealing unit 33 is in contact with the end face of thread segment 72, due to squeezing for piston head 31
Pressure can apply the extruding force of an axial direction to sealing ring 331, this pressure can promote sealing ring 331 that elastic deformation will occur, make
Sealing ring 331 internal diameter reduce, outer diameter increases, therefore the inner wall of sealing ring 331 can fit with flowline 71, and outer wall can be with
The inner wall of connecting cylinder 5 fits, so that flowline 71 is completely isolated with external environment, air is avoided to be in contact with insulating oil.
Further, since sealing ring 331 needs to occur during the work time elastic deformation, therefore the degree of aging of sealing ring 331 determines
The sealing performance of the present apparatus.In the present embodiment, sealing unit 33 is detachably connected with piston head 31, optionally, in piston
First 31 top surface is equipped with cyclic annular grooving 311, and connection screw thread is equipped with inside cyclic annular grooving 311, in the bottom surface of pedestal 332
It is equipped with matched nipple joint 3321.When being installed, the nipple joint 3321 is inserted into cyclic annular grooving 311
Portion, and the connection between pedestal 332 and piston head 31 is realized by screw thread, once aging occurs for sealing ring 331, can in time into
Row disassembly replacement, ensures that the present apparatus possesses good sealing performance always.
Optionally, the inside of the sealing ring 331 be equipped with ring cavity 3311, the axis of the ring cavity 3311 with it is close
The axis of seal 331 coincides.Extruding force needed for ring cavity 3311 is arranged can reduce sealing ring 331 deformation occurs, makes

By length, after piston mechanism rises, second back-moving spring 35 will be stretched.Due to the presence of lockable mechanism, piston mechanism
In extension elongation, its position will be fixed, therefore when the present apparatus is worked, and second back-moving spring 35 is always in stretching shape
State, once sampling work terminates, lockable mechanism will release the locking of driving mechanism, and second back-moving spring 35 will be right at this time
Piston mechanism applies a downward pulling force, promotes piston mechanism to reset rapidly, improves the removal efficiency of the present apparatus.
In addition, further to promote the working efficiency of the present apparatus, the indexing circumference of the toothed wheel 21 is tooth-like recesses
2-4 times of length.Since toothed wheel 21 is the state that is meshed with tooth-like recesses 321, the rotational travel of toothed wheel 21 is
The lifting travel of tooth-like recesses 321, when the perimeter of toothed wheel 21 be greater than tooth-like recesses 321 length when, toothed wheel 21 it is small size
Degree rotation can trigger the significantly displacement of piston mechanism.Illustratively, when the indexing circumference of toothed wheel 21 is tooth-like recesses
At 3 times of 321 length, toothed wheel 21 rotates 120 ° of height that piston mechanism can be driven to rise a tooth-like recesses 321.In reality
In the work of border, oil-immersed transformer may be arranged at higher position, therefore operator is in the sampling for carrying out insulating oil
It needs to carry out high altitude operation in journey, the installation and removal efficiency by promoting the present apparatus can effectively shorten staff in height
The aerial time can not only promote the sample rate of insulating oil, additionally it is possible to reduce the construction risk of staff.
The course of work of the present embodiment is illustrated below:
Before being sampled work, check that the degree of aging of sealing ring 331 can carry out the present apparatus if aging does not occur
Installment work need to replace sealing unit 33, then carry out the installment work of the present apparatus if aging has occurred.
When being installed, the static of pedestal 1 is kept, and makes connecting cylinder 5 and the thread segment 72 of sampling valve 7 relatively just, with
It is rotatablely connected cylinder 5 afterwards, so that the relative position between the present apparatus and sampling valve 7 is fixed.Next, rotation handwheel 23, leads to
Mechanism of overdriving promotes piston mechanism to be risen, until sealing unit 33 and sampling valve 7 fit closely position.
Sampling valve 7 is then turned on, so that the insulating oil in transformer flows into the present apparatus by flowline 71, recycles sampling
Syringe is sampled work, so that insulating oil to be measured enters in sampling bottle.
After sampling, first drop-down holds block 44, so that latch 41 exits backlash, by second back-moving spring 35
Elastic force makes piston mechanism restore home position, cylinder 5 to be then rotatablely connected, so that the present apparatus is separated with sampling valve 7.
Effect explanation is carried out to the present embodiment below:
A kind of insulating oil detection sampler is present embodiments provided, it is real using the cooperation of driving mechanism and piston mechanism
