The utility model devises, and the mode of amplifying according to application line wheel transmission ratios is coupled to each other wheeled to float, pointer, stretcher and line amplifier.
The utility model devises, the wheeled amplifier of line be set to comprise wiredly take turns I, line wheel II and cotton rope, stretcher is set to corrugated tube,
Line wheel I and line wheel II are set to rotary type connection respectively and cotton rope is set to be wound around on online wheel I and line wheel II respectively, corrugated tube is arranged in transformer oil sap cavity body and float is set to connect with corrugated tube, the end, one end of cotton rope exports after being set to wrap wire wheel I and to connect with the free end of corrugated tube and the other end end of cotton rope is set to wrap wire that to take turns II rear output be the free end connected with balancing weight, and the other end end of cotton rope is provided with pointer.
The utility model devises, and diameter and the line of line wheel II take turns the ratio setting of the diameter of I for being greater than.
The utility model devises, and line wheel I and line wheel II are set to coaxial-type rotation connection and line wheel I and line wheel II are set to superposing type distribution.
The utility model devises, and the side of pointer is provided with rule and the spacing distance of rule is set to linearly distribute.
In the technical program, float, pointer, stretcher and the wheeled amplifier of line that application line wheel transmission ratios is amplified are important technical characteristic, in the technical field of the oil level display device for transformer, have novelty, creativeness and practicality, the term in the technical program is all to make an explanation with patent documentation in the art and to understand.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
Fig. 1 is schematic diagram of the present utility model:
Fig. 2 is scheme of installation of the present utility model.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
Fig. 1 is an embodiment of the present utility model, illustrates the present embodiment by reference to the accompanying drawings, comprise wiredly take turns I 1, line wheel II 2, corrugated tube 3, float 4, cotton rope 5 and pointer 6,
Line wheel I 1 and line wheel II 2 are set to rotary type connection respectively and cotton rope 5 is set to be wound around on online wheel I 1 and line wheel II 2 respectively, corrugated tube 3 is arranged in transformer oil sap cavity body and float 4 is set to connect with corrugated tube 3, the end, one end of cotton rope 5 exports after being set to wrap wire wheel I 1 and to connect with the free end of corrugated tube 3 and the other end end of cotton rope 5 is set to wrap wire that to take turns II 2 rear outputs be the free ends connected with balancing weight, and the other end end of cotton rope 5 is provided with pointer 6.
In the present embodiment, line wheel II 2 diameter and line take turns the ratio setting of the diameter of I 1 for being greater than 1.
In the present embodiment, line wheel I 1 and line wheel II 2 be set to coaxial-type rotate connect and line wheel I 1 and line wheel II 2 be set to superposing type distribution.
In the present embodiment, the side of pointer 6 is provided with rule and the spacing distance of rule is set to linearly distribute.
When transformer oil level changes, by float 4, corrugated tube 3 is changed, drive pointer 6 to move by cotton rope 5, the ratio of taking turns the diameter of I 1 according to diameter and the line of line wheel II 2 changes distance to corrugated tube 3 and amplifies.
