Abstract
The utility model belongs to the technical field of gas tank engineering, relates to a thin oil seal-type gas tank, and particularly discloses an anti-freeze mechanical gauge aiming at the north dry-type gas tank mechanical gauge. By adding a baffle plate at the entry slot of a wire cable and leading the height of the baffle plate to exceed the local largest snow depth in winter, or changing the entry direction of the wire cable into a gear box by a guide wheel and leading the entry slot of the wire cable to be positioned on the side wall or the bottom of the gear box body, the melted snow is prevented from entering the gear box, thus guaranteeing the normal operation of the mechanical gauge in winter and creating conditions for the safe and reliable operation of the gas tank in winter. The utility model is simple and reliable, and can be widely applied to the north dry-type gas tank mechanical gauge.
Description
Technical field
The utility model belongs to the gas cabinet field of engineering technology, relates to a kind of thin-oil sealed gas tank, particularly open a kind of anti-freeze type machinery level meter at northern dry gas holder machinery level meter.
Technical background
The gas cabinet gas-storing capacity signal parameter of machinery level meter transmission is very important concerning the operator, even because under situation about having a power failure, the operator also can recognize the gas-storing capacity of gas cabinet by mechanical level meter, formulates safe and reliable counter-measure.The gas-storing capacity of the dry gas holder of using is measured by a kind of mechanical level meter measurement position of piston height at present.Its principle is as depicted in figs. 1 and 2:
In dry gas holder 1, be fixed with wire rope 3 on the piston 2, wire rope 3 arrives the outside of gas cabinet 1 after upper saw pulley 4 is changed direction on the gas cabinet cabinet top, through the wire rope inlet slot 12 of tens meters high backs to the mechanical level meter transmission case cover plate 5 that is installed in gas cabinet 1 outside; Because the general about 50～100m of the piston stroke of dry gas holder, the general velocity ratio that changes in transmission case casing 6 is so that the signal of output piston height.Cable drum is supported on the transmission case casing 6 by axle 9, and the parent roll 7 that is connected with wire rope 3 is connected with the rouleau tube 10 that hangs with tension steel wire rope and weight 11 through sprocket wheel 8.
According to investigation to the dry gas holder of having gone into operation, discovery is at upper saw pulley place, cabinet top, taked the measure of prevention ice and snow disaster, but to winter, the north is still because the cover plate of mechanical level meter transmission case is a level, and accumulated snow is on the cover board because cause melts such as sunshine are fallen frozen on the reel, causes wire rope not reach the requirement of gas cabinet stroke and pulls apart, cause mechanical level meter to lose efficacy, tension steel wire rope and weight are pounded earthward.
Summary of the invention
The purpose of this utility model is to provide a kind of a kind of antifreeze mechanical level meter that prevents northern dry gas holder wire cable rupture.By adding baffle plate at wire rope inlet slot place, the height of baffle plate surpasses locality maximum snow depth in winter, perhaps upper saw pulley change wire rope enter transmission case Way in, the wire rope inlet slot is positioned at the sidewall of transmission case casing or is positioned at the bottom of transmission case casing.Prevent that the snow-broth that melts from entering transmission case inside, guarantee the normal operation in winter of mechanical level meter, the safe and reliable operation of gas cabinet creates conditions for winter.
Description of drawings
Fig. 1 is a dry gas holder machinery level meter schematic diagram
Fig. 2 is mechanical level meter transmission case cover plate schematic representation
Fig. 3 is the utility model transmission case cover plate overhead gage schematic representation
Among the figure, part 1 is a dry gas holder; Part 2 is a piston; Part 3 is a wire rope; Part 4 is a upper saw pulley; Part 5 is the transmission case cover plate; Part 6 is the transmission case casing; Part 7 is a parent roll; Part 8 is a sprocket wheel; Part 9 is an axle; Part 10 is little reel; Part 11 is tension steel wire rope and weight; Part 12 is the wire rope inlet slot; Part 13 is a baffle plate.
Embodiment
3 the utility model is described in further detail in conjunction with the accompanying drawings:
Increase baffle plate 13 around the wire rope inlet slot on the existing transmission case cover plate 5 12, the height of baffle plate 13 surpasses maximum snow depth in local winter, prevents that the snow-broth that melts from entering transmission case inside, guarantees the normal operation in winter of mechanical level meter.
Adopt the mechanical level meter of the utility model patent, can solve the problem that machinery level meter wire rope is pulled apart when snowing winter effectively.Though a small amount of snowflake can waft in the transmission case when snowing, snow at temperature at that time and can not melt and have not big harm; When snow melting, a small amount of snow-broth in the case can flow out from the hole of lower box very soon, baffle plate will be isolated in snow-broth on the casing and the transmission case, guaranteed the reliable operation of gas cabinet machinery level meter, thus for severe winter gas cabinet safety operation and production scheduling gas-storing capacity information accurately is provided.
The utility model can also by upper saw pulley change wire rope enter transmission case the Way in mode of isolating snow-broth realize that the wire rope inlet slot is positioned at the sidewall of transmission case casing or is positioned at the bottom of transmission case casing.
The utility model is simple and reliable, can be widely used on the northern dry gas holder machinery level meter.
