Abstract

A gravity-triggered shear pin signal measuring alarm component relates to the signal measuring technology and solves the problems that the existing shear pin signal measuring component is failed in triggering, the alarm means is single, and the fault finding is difficult. A conductor plate of the gravity-triggered shear pin signal measuring alarm component is a basin structure; a battery compartment is disposed inside the conductor plate structure, and the battery compartment is used for arranging a battery; the positive electrode of the battery is connected with a positive plate, and the negative electrode of the battery is connected with a negative plate; an alarm circuit is used for sending an alarm signal, the positive input end of the alarm circuit is connected to the positive plate,and the negative of the alarm circuit is connected to a conductor plate; one end of an all-copper counter weight is elastically connected to the bottom surface of the negative plate; the other end ofthe all-copper counter weight passes through the bottom of the conductor plate without contact, then extends into a ceramic bottom case, and is supported by the bottom of the ceramic bottom case, at this time, the negative plate is disconnected with the conductor plate; when the bottom of the ceramic bottom case is broken by shear force, the negative plate and the conductor plate are in a conducting state. The beneficial effect is that the high reliability alarm means is rich and timely.

Description

technical field [0001] The invention relates to a signal measurement technique. Background technique [0002] Generally, the trigger mode of the existing shear pin signal device is to start with a spring tension contact: [0003] This method relies on the pull rod to compress the spring and lock it on the discontinuous part. When the discontinuous part encounters shear force, it breaks, and the pull rod returns to the closed contact under the force of the spring to make the circuit conduct and realize the alarm output. [0004] The disadvantages are: 1. When the component is in service for too long, the spring tension is lost and the contacts cannot be effectively closed; [0005] 2. There is a certain probability that the pull rod will be blocked by the shearing part and the contact cannot be closed. [0006] At the same time, the alarm output only provides a passive normally open or normally closed contact structure; the alarm means is single, and the fault location cann...
