Seat, spring and liquid nitrogen container, the spring are placed on pedestal, and liquid nitrogen container is placed on spring, and report is also equipped on the pedestal
Device is warned, touch block is installed on liquid nitrogen container, when liquid nitrogen weight is greater than predetermined low value in liquid nitrogen container, spring is in contraction state,
The underface that block is located at alarm switch is touched, when liquid nitrogen weight is less than or is equal to predetermined low value in liquid nitrogen container, touches block
Touch alarm switch.
The pedestal is made of lower supporter with the traveling wheel for being mounted on lower supporter bottom end, and the lower supporter includes five connecting rods
With the perpendicular bar being connected on five connecting rod outer ends, the inner segment of five connecting rods is interconnected to constitute pentagon, every connecting rod outer end
A traveling wheel is installed in lower section respectively, wherein being equipped with alarm, the connection component by connection component on a perpendicular bar
Including fixed link and rotating bar, rotating bar is mounted in fixed link by shaft, and rotational positioning bar is provided in fixed link, alarm
Device is mounted in rotating bar.
It further include having the anti-down component of guiding, the anti-down component of guiding includes annular sleeve and the branch for being mounted on annular sleeve lower end
The internal diameter of support leg, the annular sleeve is outer through big 1-5cm than liquid nitrogen container.
The alarm is combined aural and visual alarm.
Due to the adoption of the above technical scheme, the utility model has the following beneficial effects:
1, structure is simple, cheap.The utility model only needs to increase pedestal and spring, alarm, does not need
Expensive electronic system, is a kind of mechanical alarming devices using gravity.Spring is installed in the submounts of liquid nitrogen container,
When filling it up with liquid nitrogen in liquid nitrogen container, gravity is big, and liquid nitrogen container is pressed downward that spring is made to sink, and spring is in contraction state, liquid nitrogen
Touch block on tank is located at the underface of alarm switch, i.e. touch block is not contacted with alarm switch；When liquid nitrogen is with the time
And volatilize, the gravity spring that becomes smaller bounces, and when liquid nitrogen weight is less than or is equal to predetermined low value in liquid nitrogen container, touches block touching report
Alert device switch, alarm equipment alarm remind laboratory worker to add liquid nitrogen.
2, the expenditure of alarm expense is reduced.Existing alarm system is import equipment, it is also necessary to which expensive electronic system needs
It will carry out telephone recharge every month, replacement battery yet needs an expense, and the utility model does not need these expenses, at
This is low.
3, the ratio for wrong report occur, prolonging report is reduced.The utility model is purely mechanic equipment, the electronic system of no precision,
The case where reporting by mistake because of accidentally electronic system is touched will not occur in addition liquid nitrogen or other operating process.In addition, this is practical new
Type be not in because forget to replace battery and pay the fees telephone expenses due to can not Normal Alarm the case where, therefore the case where prolonging report hair can be reduced
It is raw.
In the following, in conjunction with the accompanying drawings and embodiments to a kind of gravity type embryo experiments liquid nitrogen warning device of the utility model
Technical characteristic is further described.
