Description
Technical field
the utility model relates to a kind of pick-up unit, relates in particular to a kind of leak detecting device.
Background technology
Oil tank of transformer, after the use through the long period, inevitably there will be surface damage, and the blind crack that this surface damage brings will cause oil tank of transformer to leak.This blind crack normally naked eyes is inconspicuous, and after leaking, near bulk zone leakage point, will be covered with greasy dirt, and it is very difficult that this makes to find out leakage point by naked eyes.
In order to find out the leakage point of oil tank of transformer, after conventionally oil tank of transformer disassembly, cleaning need to being completed, relend and help professional magnify tool to scan oil tank of transformer surface, just so can accurately determine the position of leakage point.Whole process is very loaded down with trivial details, wastes time and energy.
Utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of oil tank of transformer sniffer that can detect the leak source position of oil tank of transformer without dismounting oil tank of transformer is provided.
The purpose of this utility model is achieved through the following technical solutions:
Oil tank of transformer sniffer, comprising: sucker; The delivery pipe that upper end is communicated with sucker, delivery pipe consists of transparent plastic; Liquid storage cartridge, liquid storage cartridge is communicated with the rear end of delivery pipe, and liquid storage cartridge consists of transparent plastic; Wherein, the rear end of delivery pipe is run through the top of liquid storage cartridge and is extended to the bottom of liquid storage cartridge; Wherein, delivery pipe is positioned on the tube wall of part of liquid storage cartridge inside and is provided with cavity, and the top of cavity offers the duct being communicated with outside, stores acid base indicator in cavity.
The utility model, when work, is adsorbed on a bit on oil tank of transformer by sucker, and this some place is doubtful leakage point.If this some place is leakage point really, from the transformer oil of this leakage, by delivery pipe, enter in liquid storage cartridge so, along with the liquid level of the transformer oil in liquid storage cartridge raises gradually, transformer oil passing hole channel enters in cavity and contacts with acid base indicator, because transformer oil is acid, acid base indicator variable color.Staff can confirm whether the point of sucker absorption is leakage point intuitively according to the color of acid base indicator.If sucker is in the long period after this point of absorption, acid base indicator does not have variable color, can determine that this point is not leakage point, and near other doubtful leakage point that staff can be adsorbed on sucker this point detects.
Further, also comprise the arm A being communicated with the top of described liquid storage cartridge; Also comprise the flexiplast ball being communicated with the end of described arm A.
By extruding flexiplast ball, the gas in liquid storage cartridge can be drawn in flexiplast ball, make maintenance negative pressure in liquid storage cartridge, thereby can make the transformer oil that leakage point place spills enter faster in liquid storage cartridge, shortened detection time.
Further, also comprise the arm B being arranged on described arm A, be arranged at the retaining valve B on arm B, be arranged at the retaining valve A on arm A; Retaining valve A is between described liquid storage cartridge and arm B, and retaining valve A is configured to make the gas in described liquid storage cartridge to enter described flexiplast ball; Retaining valve B is configured to make outside the gas exhaust outlet B in described flexiplast ball.
Extruding flexiplast ball, the gas in flexiplast ball is discharged by retaining valve B, unclamps flexiplast ball, and the gas in liquid storage cartridge is inhaled in flexiplast ball by retaining valve A.So repeatedly, can negative pressure will be evacuated in liquid storage cartridge.
Further, the top of described liquid storage cartridge offers up big and down small conical through-hole; Also comprise taper plug, on taper plug, offer manhole; Described delivery pipe runs through manhole, and taper plug embeds in conical through-hole.
Taper plug in inserting conical through-hole after, conical through-hole extruding taper plug deforms taper plug, thereby makes the inwall of manhole be close to delivery pipe outside surface, to realize sealing, prevents from that foreign material from entering in liquid storage cartridge testing result is impacted.
Further, also comprise the draw ring being connected with described taper plug top.
By draw ring, can easily taper plug be extracted to conical through-hole, thereby delivery pipe is taken out from liquid storage cartridge, so that acid base indicator is changed.
Further, also comprise the sheet metal pasting with described cavity inner wall surrounding, on sheet metal, offer at least one viewport.
Because delivery pipe integral body consists of transparent plastic, in liquid storage cartridge, to be pumped into after negative pressure, the part that may cause delivery pipe to be positioned at liquid storage cartridge inside produces distortion, and the acid base indicator in cavity is overflowed.For fear of above-mentioned situation, sheet metal is set in cavity, increase the structural strength of cavity, prevent Wall deformation.Meanwhile, on sheet metal, offer viewport, so that staff observes the color of acid base indicator.
In sum, advantage of the present utility model and beneficial effect are:
1. by the utility model, without dismounting oil tank of transformer, can detect the leakage point of oil tank of transformer;
2. by the utility model, staff can confirm whether the point of sucker absorption is leakage point intuitively according to the color of acid base indicator, easy to use directly perceived;
3. flexiplast ball is set, by extruding flexiplast ball, the gas in liquid storage cartridge can be drawn in flexiplast ball, make maintenance negative pressure in liquid storage cartridge, thereby can make the transformer oil that leakage point place spills enter faster in liquid storage cartridge, shorten detection time;
4. arm B, retaining valve A and retaining valve B are set, by extruding flexiplast ball, can will in liquid storage cartridge, be evacuated to negative pressure more reliably;
5. by taper plug and conical through-hole, realize sealing, prevent from that foreign material from entering in liquid storage cartridge testing result is impacted;
6. draw ring is set, by draw ring, can easily taper plug be extracted to conical through-hole, thereby delivery pipe is taken out from liquid storage cartridge, so that acid base indicator is changed;
7. sheet metal is set in cavity, increases the structural strength of cavity, prevent Wall deformation, meanwhile, on sheet metal, offer viewport, so that staff observes the color of acid base indicator.
