Description

A kind of gravity triggering break pin signal measurement alarm element
Technical field
The present invention relates to a kind of signal measurement techniques.
Background technique
The triggering mode of general existing shear pin signal device is started using spring tension contact:
Such method will be locked in discontinuities by pull rod after spring compression, be fractureed when discontinuities meet with shearing force, Pull rod returns to closure contact under spring force, and circuit is connected, and realizes warning output.
Its drawback is:1. spring tension loss causes contact effectively closed when element active time is too long;
Cause contact that can not be closed by cutting portion card resistance 2. pull rod has certain probability.
Meanwhile warning output only provides passive normally opened or normally closed type contact structure;Alarm means are single, after alarm occurs It can not quickly indicate abort situation, bring bulk redundancy to work for subsequent maintenance.
Summary of the invention
The purpose of the present invention is to solve the triggerings of existing break pin signal measurement element to fail, alarm means are single, event Barrier searches difficult problem, proposes a kind of gravity triggering break pin signal measurement alarm element.
A kind of gravity triggering break pin signal measurement alarm element of the present invention include ceramic bottom case, full copper weight, Conductor part, battery warehouse and warning circuit;
The conductor part includes positive plate, negative plate and conductor plate;
Conductor plate is basin body structure;
The inside of conductor plate basin body structure is arranged in the battery warehouse, and battery warehouse is for placing battery;Battery is just Pole is connected with positive plate, and the cathode of battery is connected with negative plate;
For issuing alarm signal, the electrode input end of warning circuit is connected the warning circuit with positive plate, alarm electricity The negative input on road is connected with conductor plate;
One end elasticity of the full copper weight is mutually connected on the bottom surface of negative plate;The other end of full copper weight is non-contact to be passed through It extends to behind conductor plate bottom in ceramic bottom case, it is carried by the bottom of ceramic bottom case, negative plate and conductor plate are disconnected at this time Open state;When the bottom of ceramic bottom case is crushed by shearing force, negative plate and conductor plate are on state.
The operation principle of the present invention is that:When the measurement alarm element is not by shearing force, full copper weight is held by ceramic bottom case It carries, negative plate does not issue any alarm signal at this point, warning circuit can not constitute access in not contact condition with conductor plate;When When the measurement alarm element is by shearing force, ceramic bottom case bottom is broken, and full copper weight is due to losing carrying, in the work of gravity It is moved straight down under, full copper weight is caused to contact with conductor plate, at this point, the electrode input end of warning circuit passes through positive plate Be connected with anode, the cathode output end of warning circuit pass sequentially through after conductor plate, full copper weight and negative plate with battery Cathode is connected, i.e., warning circuit constitutes access, issues alarm signal, realizes the monitoring to break pin signal.
The beneficial effects of the invention are as follows the gravity by full copper weight to trigger alarm, therefore the measuring cell is with highly reliable Property, improve the accuracy of device action;Since the alarm signal of warning circuit is not limited to one or more, alarm Means are abundant, and due to the cleaning of alarm signal fault point as it can be seen that easy-to-look-up failure, to exclude in time.
The present invention is applied to vertical hydrogenerator.
