Description

A kind of Simple seismometer

Technical field

The utility model relates to seismic surveying field, is a kind of Simple seismometer specifically.

Background technology

Known by everybody, earthquake is the great natural hazard of a kind of destructive power, along with the increase of earthquake magnitude, its destructive power also significantly promotes, there is Tangshan Earthquake, Wenchuan violent earthquake in China, all caused huge loss to society, and earthquake while just having started people be often not aware of, and quality time of having lost escape.

At present, the existing seismograph predicting an earthquake is a lot, domestic earthquake prediction net builds up, but the seismograph using is advanced in performance, complex structure, bulky, and price is very high, be not suitable for extensively universal and popularization of town and country, common people cannot have such seismograph, and China is an earthquake the take place frequently country in district, carry out the outreach work of Earthquake Knowledge, make people understand more quakeproof escape knowledge, simultaneously in family, office, the place that the people such as school are many is used placement seismograph to make people can grasp in time the information before earthquake occurs, strive for the more time and reduce the loss for hiding earthquake.

Summary of the invention

In view of this, the utility model provide a kind of and simple in structurely, convenient resetted, with low cost and be convenient to universal Simple seismometer and control circuit thereof.

In order to solve the problems of the technologies described above, the utility model provides a kind of Simple seismometer, comprise rectangular housing and be positioned over the Metal Ball in housing, the centre position of housing is provided with a circular cavity, cavity uses translucent cover sealing, and the bottom centre position of cavity is fixed with the pillar of a Metal Ball, and pillar edge is provided with by the down-side tilt smooth bevel in upper end, the upper end on this inclined-plane is undertaken in pillar outer, between lower end, inclined-plane and the sidewall of cavity, has certain spacing; Housing be provided with warning light, warning horn and battery, between warning light, warning horn and battery by gauge tap and contact-making switch control; Between the positive pole of battery and negative pole, series connection accesses gauge tap, warning light and contact-making switch successively, at the two ends of warning light access in parallel warning horn.

As improvement of the present utility model, non-conductive between described inclined-plane and cavity sidewalls, the spacing between lower end, inclined-plane and cavity sidewalls is less than the diameter of Metal Ball.

As improvement of the present utility model, described contact-making switch is made up of two conducting metal circles that are arranged on annular slope and cavity sidewalls, is connected two quoits and realized the break-make of contact-making switch by Metal Ball.

As further improvement of the utility model, described translucent cover is by the chimeric cavity surface that is fixed on.

Compared with prior art, the utlity model has mechanism simple, easily manufacture, with low cost, workable, be convenient to universal in society and promote; Can detect in advance that earthquake occurs, warning personnel, for the valuable time is striven in escape, can use in the many places of the people such as family, office, school.Also there is auto-reset function simultaneously, convenient operation, practical.

Embodiment

In order to allow those skilled in the art understand better the technical solution of the utility model, below in conjunction with accompanying drawing, the utility model is further elaborated.

As Fig. 1, shown in Fig. 2 and Fig. 3, the utility model provides a kind of Simple seismometer, comprise rectangular housing 1 and be positioned over the Metal Ball 2 in housing, the centre position of housing 1 is provided with a circular cavity 11, cavity 11 openings use translucent cover 12 to seal, the bottom centre position of cavity 11 is fixed with the pillar 13 of a Metal Ball, pillar 13 center is provided with the concave surface of placement and balance Metal Ball, pillar 13 edges are provided with by the down-side tilt smooth bevel 14 in upper end, the upper end on this inclined-plane 14 is undertaken in pillar 13 outers, between 14 lower ends, inclined-plane and the sidewall of cavity 11, there is certain spacing.Be equipped with quoit 3 on inclined-plane 14 and cavity 11 sidewalls, quoit 3 is respectively along the annular spread of inclined-plane and cavity sidewalls.Non-conductive between inclined-plane 14 and cavity 11 sidewalls, the spacing between inclined-plane 14 and the sidewall of cavity 11 outers is less than the diameter of Metal Ball 3.Be provided with warning light 4 and warning horn 5 in the upper surface of housing, for warning light 4 and warning horn 5 provide the battery 6 of power supply to be placed in housing, between warning light 4, warning horn 5 and battery 6, control by gauge tap 71 and contact-making switch 72; Between the positive pole of battery 6 and negative pole, series connection accesses gauge tap 71, warning light 4 and contact-making switch 72 successively, at the two ends of warning light 4 access in parallel warning horn 5.Excessive in order to prevent electric current, the resistance R of having connected between warning lamp 4 and contact-making switch 72.Contact-making switch 72 is made up of two conducting metal circles that are arranged on annular slope and cavity sidewalls, is connected two quoits and realized the break-make of contact-making switch 72 by Metal Ball.After Metal Ball 2 vibrations, fall between lower end, inclined-plane and cavity sidewalls, and be connected in the quoit of inclined-plane and cavity sidewalls.

When original state, in the concave surface of Metal Ball 2 in pillar 13.In the time detecting that earthquake occurs, because making Metal Ball 2, vibration departs from the concave surface of pillar 13, now, because inertia Metal Ball 2 falls between an inclined-plane 14 and cavity 11 sidewalls along inclined-plane, the Metal Ball falling between inclined-plane 14 and cavity 11 sidewalls contacts with two quoits 3.

In the time of every day use, by gauge tap 71 closures, contact-making switch 72 is made up of two conducting metal circles 3 that are arranged on annular slope 13 and cavity 11 sidewalls, in the time there is not earthquake, Metal Ball 2 is on pillar 13, quoit 3 between inclined-plane 13 and cavity 11 sidewalls cannot conducting, thereby circuit is disconnected; In the time that earthquake will occur, the vibration of earthquake shakes Metal Ball 2 from pillar 13, fall between inclined-plane 14 and cavity 11 sidewalls from pillar 13, thereby realize the conducting of contact-making switch 72 by the circuit of two quoits 3 of Metal Ball 2 conduction connections, the conducting of circuit makes warning lamp 4 and attention device 5 that warning information occur, and realizes earthquake pre-warning.

When seismograph need to disconnect gauge tap 71 when changing battery, now Metal Ball 2 falls between inclined-plane 13 and cavity 11 sidewalls, and circuit still disconnects, warning light 4 and warning horn 5 cisco unity malfunctions.

Above-described embodiment is only wherein specific implementation of the present utility model, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to the utility model the scope of the claims.It should be pointed out that for the person of ordinary skill of the art, without departing from the concept of the premise utility, can also make some distortion and improvement, these apparent replacement forms all belong to protection domain of the present utility model.
