Embodiment
Describe in detail below in conjunction with accompanying drawing.
Present embodiment comprises copper sheet 1, electromagnet 2, spring 3, armature 4, pillar 5, moving contact 6, stationary contact 7, alarm 8, accumulator 9, protective sleeve 10, compound substance 11, Graphite cloth 12.Electromagnet 2 one ends are connected with copper sheet 1, and electromagnet 2 other ends are connected with Graphite cloth 12, and electromagnet 2 tops are armature 4; Electromagnet 2 is 5mm with armature 4 distances, and armature 4 is hingedly fixed on the pillar 5, can be around the rotation of pillar 5 fulcrums; Armature 4 one ends are connected with spring 3; Armature 4 other ends are connected with moving contact 6, and moving contact 6 belows are stationary contact 7, and moving contact 6 is 4mm with stationary contact 7 distances; Stationary contact 7 is connected with alarm 8 and accumulator 9; Protective sleeve 10 is made in copper sheet 1, electromagnet 2, spring 3, armature 4, pillar 5, moving contact 6, stationary contact 7, alarm 8, accumulator 9 outsides, and protective sleeve 10 outsides are compound substance 11, and Graphite cloth 12 is pasted in compound substance 11 outside embeddings.
When cement stone receives earthquake pressure; Compound substance 11 can produce electric current, and copper sheet 1, electromagnet 2, compound substance and Graphite cloth 12 form closed circuit, and electromagnet 2 energisings are magnetic; Inhale lower armature 4; Moving contact 6 is contacted with stationary contact 7, and alarm 8 operating circuits are closed, and alarm 8 sends alarm sound.When compound substance recovered normal condition, electromagnet 2 outages lost magnetism.Spring 3 tightens up reinstatement, and armature 4 pull-ups, moving contact 6 separates with stationary contact 7 through leverage, and alarm 8 operating circuits break off, and alarm 8 stops to send alarm sound.
Earthquake alarm cement is made of stones to be comprised as step:
(1) pre-service zinc paste
Zinc paste is carried out hydrogen anneal process.
Hydrogen anneal process zinc paste can make resistivity decreased 5～6 one magnitude of Zinc oxide particles, and lowest resistivity reaches 8 * 10
-3Ω cm.Hydrogen anneal process makes carrier concentration and mobility increase; Thereby making resistivity decreased. the reason that causes carrier concentration to increase mainly is summed up as hydrogen anneal process makes electronics free the constraint and the effusion of grain boundary adsorb oxygen of trap level; The grain boundary potential barrier is descended, thereby film resiativity is descended.
(2) pre-service volcanics fiber
The volcanics fiber is put into water, and the water yield is about 60% of total water amount, carries out pre-dispersedly with ultrasonic continuous vibration 30min, and temperature is controlled between 38～42 ℃ during concussion.
(3) add spreading agent hydroxyethyl cellulose and foam-breaking agent tributyl phosphate and water reducer wood calcium
Adopt batch (-type) to control automatically and stir appearance stirring 3min; Speed is 20～30r/min, and drips foam-breaking agent tributyl phosphate, ultrasonic again concussion 30min; Stir 5min with stirring appearance again; Speed is 30～40r/min, and this moment, the volcanics fiber was the monofilament state basically, in mixed liquor, adds water reducer wood calcium.
(4) add cement and surplus water
The employing batch (-type) stirs, and first quick and back slow, speed is 50～70r/min, and mixing time is 4～5min.
(5) moulding
The material for preparing is joined mould, and copper sheet 1, electromagnet 2, spring 3, armature 4, pillar 5, moving contact 6, stationary contact 7, alarm 8, accumulator 9, protective sleeve 10 are placed by mould central authorities.Forming method adopts compression moulding, and forming pressure adopts 12MPa, the inboard Graphite cloth of pasting 3 * 3cm of mould, and conductive wire inweaves Graphite cloth, and Graphite cloth is as powered electrode.
Closely knit forming pressure can influence the resistivity of earthquake alarm cement stone.Forming pressure is high more, and earthquake alarm cement stone is more closely knit, and porosity is little, thereby electric conductivity is better; Pressure acts on the spacing that also can shorten the volcanics fiber greatly to " compression " of compound, increases the overlap joint degree of volcanics fiber, makes along the electronic conduction of volcanics network of fibers to be able to strengthen; Simultaneously, volcanics fiber under the pressure effect and cement stone get an electric shock indirectly to hinder and also will diminish.In addition, the shortening of volcanics fiber spacing, also making former between part volcanics fiber is that main electricity leads that to become with the electronic conduction be that main electricity is led with the ionic conduction, all these has strengthened the electric conductivity of earthquake alarm cement stone greatly.Test shows that other forming pressures were minimum relatively for earthquake alarm cement stone resistivity when forming pressure was 12MPa.
(6) drying
Put into reverse-flow tunnel drier to warning cement stone.The relative humidity of preheating section hothouse air-flow remains 80%～95%, and temperature is 35～45 ℃.After this get into dryer section, the relative humidity of dryer section hothouse air-flow remains 30%～40%, and temperature is 55～65 ℃.
