Abstract
A kind of water-level gauge, it is cursory to comprise, it is characterized in that arranging a level scale plate be fixed on base, fixed mount above level scale plate connects cursory rope sheave and vernier rope sheave by rotating shaft coaxle, large cursory rope sheave and little vernier rope sheave are two radiuses differences and the concentric circles be fixedly connected with together, and the ratio of their rotation girth is radius ratio, and the radius ratio of cursory rope sheave and vernier rope sheave is 2.5, cursory rope sheave is fixedly connected with cursory rope, and it is cursory that cursory rope lower end connects; Vernier rope sheave is fixedly connected with vernier rope, vernier rope lower end concatenation pointer.Intuitively can show water bunker level, conveniently observe at any time, utilize safety, meet requirement of explosion proof.
Description
Technical field
The utility model belongs to a kind of water-level gauge, particularly one and is applied in underground main drainage pump sump, the water-level gauge of display water bunker level.Overcome the requirement of down-hole to explosion-proof aspect, also overcome the problem that space is little, ensure safety in production.
Background technology
Coal master's unwatering pump is the Unique Device whole water bursts of mine being discharged to ground.Just along with swallet in shaft production, can strengthen at the exploiting field water yield running into complicated hydrogeological conditions, threaten the safety of personnel.Mine main drain pump is one of the important production link in colliery.
Existing water plant water bunker level height is determined to use borehole wall ladder lattice number observation always.Also used the mode of the iron plate of mounting strap scale in water in the past, but iron plate has just been corroded use a period of time in water after.When using borehole wall ladder lattice number observation, observer need stand near sump mouth, irradiates ladder with mine lamp.The each lattice spacing of ladder is 0.3m.If ladder lattice number is 8 lattice.Using height overall 5m-8 × 0.3m=2.6m again, is water bunker level.The shortcoming of this method is as follows: 1, intuitively can not show water level.2, sump internal light is dark, mine lamp need be used to irradiate and observe.3, need to stand near sump mouth, have the danger of landing.4, the change observing water level is at any time unfavorable for.Ladder and water pump, not in the same side, can not be observed simultaneously.Therefore a kind of novel water level meter is urgently provided, to overcome the problems referred to above.
Summary of the invention
The purpose of this utility model is to overcome the problems referred to above, provides one intuitively can show water bunker level, conveniently observes at any time, utilizes safety, meet the water-level gauge of requirement of explosion proof.
The technical solution of the utility model is as follows: it is cursory to comprise, it is characterized in that: a level scale plate be fixed on base is set, fixed mount above level scale plate connects cursory rope sheave and vernier rope sheave by rotating shaft coaxle, large cursory rope sheave and little vernier rope sheave are two radiuses differences and the concentric circles be fixedly connected with together, the ratio of their rotation girth is radius ratio, the radius ratio of cursory rope sheave and vernier rope sheave is 2.5, cursory rope sheave is fixedly connected with cursory rope, and it is cursory that cursory rope lower end connects; Vernier rope sheave is fixedly connected with vernier rope, vernier rope lower end concatenation pointer.
Effect of the present utility model is as follows: 1, intuitively show water bunker level, does not need to calculate.2, water-level gauge is on sump top, well lighted, conveniently observes at any time.3, do not need to stand in sump mouth to observe, utilize safety.4, just can observe water bunker level in water pump side, be beneficial to safety.5, be entirely physical construction, meet requirement of explosion proof.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Embodiment
See Fig. 1, concrete structure is as follows: on base 6, be fixedly connected with level scale plate 4, and arrange gliding groove in the middle of level scale plate 4, transversal section is that I-shaped pointer 5 is arranged in chute; Fixed mount 8 above level scale plate 4 coaxially connects cursory rope sheave 1 and vernier rope sheave 3 by turning axle 2, large cursory rope sheave 1 and little vernier rope sheave 3 are two radiuses differences and the concentric circles be fixedly connected with together, the ratio of their rotation girth is radius ratio, the radius ratio of cursory rope sheave 1 and vernier rope sheave 3 is 2.5, cursory rope sheave 1 is fixedly connected with the upper end of cursory rope 10, cursory rope 10 lower end connects cursory 7; Vernier rope sheave 3 is fixedly connected with vernier rope 9 upper end, vernier rope 9 lower end concatenation pointer 5.Consider mine water pump house limited space, as used simply cursory, pulley, display board structure to make water level 1:1 show, space is inadequate, so use two groups of nebenkerns, the radius ratio of cursory rope sheave 1 and vernier rope sheave 3 is 2.5, to shorten length of the scale, and meets request for utilization.Therefore the scale on scaleplate 4 determines scale according to cursory rope sheave 1 and the girth ratio of vernier rope sheave 3.
The principle of work of water-level gauge: be fixed on by water-level gauge on platform, is placed on cursory in water.During water level decreasing, cursory 7 declines drive cursory rope sheave 10 to be rotated counterclockwise, and cursory rope sheave 10 drives vernier rope sheave 3 to rotate, and vernier rope sheave 3 rotarily drives pointer 5 and moves upward, and indicates water-level gauge registration.When water level goes up, cursory 7 rise, and cursory rope sheave 10 and vernier rope sheave 3 will rotate clockwise.Pointer 5 will drop to corresponding scale, reflects the change of water level accurately.
