Description

The high precision seismic pen recorder

Technical field

The utility model relates to a kind of seismograph, particularly a kind of high precision seismic pen recorder.

Background technology

Earthquake is a kind of spontaneous phenomenon of the kinetic ground vibration of earth interior, and mutual extrusion collision between earth plate and the plate causes that plate edge and plate are inner to be produced the changing of the relative positions and break, and is to cause the earth shock main cause.Earthquake has caused tremendous loss for people's lives and properties, for the loss that earthquake is brought is relieved to bottom line, many observation devices have been made in people's summing up experience for many years, but various advanced persons' seismological observation apparatus cost height, equipment complexity, need the observer to possess certain professional knowledge.

Summary of the invention

The utility model provides a kind of high precision seismic pen recorder cheap, easy to use.

The technical solution adopted in the utility model is, designs a kind of high precision seismic pen recorder, it is characterized in that; Which comprises at least the supporting mechanism of fixed support, back shaft formation, the back shaft top is a concaver, the concaver upper end is connected with balanced controls by a contact, in the closed housing of balanced controls illuminating circuit is arranged, there is the light hurdle at the corresponding closed housing of the light path of illuminating circuit place, light marge side has photoelectricity curtain sensor around one week of back shaft, and photoelectricity curtain sensor is electrically connected with interface circuit.

Described photoelectricity curtain sensor comprise at least can discern 360 the degree and up and down each 80 the row photoelectric sensor battle arrays.

In the middle of the described balanced controls balancing shaft is arranged, balancing shaft and round closed housing connect as one, and the closed housing below is divided equally around balancing shaft at least the rotation wing; The balancing shaft lower end is cone or spherical surface body, contacts with the concaver point at back shaft top.

Described rotation wing quantity is 2,3,4,6.

The described rotation wing can be round tubular body.

Described supporting mechanism and supporting mechanism are fixed in the housing, and the signal I/O of interface circuit is fixed on the opening of housing one side.

The course of work of the present utility model and advantage are: the back shaft top is a concaver, the concaver upper end is connected with balanced controls by a contact, when earthquake takes place, ground produces and rocks, balanced controls rock with ground, illuminating circuit in the balanced controls forwards sends light signal by the light hurdle, and light marge side is around the photoelectric sensor curtain is arranged in one week of back shaft, the photoelectric sensor curtain will be noted ground and produce intensity and angle displacement information when rocking, this information of photoelectric sensor curtain record outputs to computing machine by interface circuit or remote control center is handled, the true record of situation is rocked on ground when showing the earthquake generation, rolls over back-up.Owing to be connected with balanced controls by a contact, balanced controls send light signal, and by photoelectricity curtain sensor record, therefore have highly sensitive, high-precision characteristics.

Description of drawings

The utility model is described in further detail below in conjunction with the embodiment accompanying drawing.

Fig. 1 is the utility model example structure synoptic diagram;

The record synoptic diagram of situation was rocked on ground when Fig. 2 was the earthquake generation.

Among the figure: 1, casing; 2, Guang Lan; 3, closed housing; 4, photoelectricity curtain sensor; 5, the rotation wing; 6, conehead; 7, conehead support slot; 8, interface circuit; 9, light emitting diode; 10, fixed support; 11, photoelectric sensor; 12, back shaft; 13, balancing shaft; 14, illuminating circuit.

Embodiment

As shown in Figure 1, be included in the fixed support 10 on the casing 1, the supporting mechanism that back shaft 12 constitutes, back shaft 12 is vertically fixed on the fixed support 10, and back shaft 12 tops are concaver.One balanced controls are fixing by contacting with concaver point, and when not having the shake generation, balanced controls are in equilibrium state.

Balanced controls comprise balancing shaft 13, illuminating circuit 14, photoelectricity curtain sensor 4, the rotation wing 5 and closed housing 3.Balancing shaft 13 connects as one with round closed housing 3, and balancing shaft 13 lower ends are cone or spherical surface body, and the conehead 6 of cone or spherical surface body is connected by the some contact with the conehead support slot 7 of the concaver at back shaft 12 tops, increases the sensitivity of earthquake detection.The rotation wing 5 is fixed as one below closed housing 3.The quantity of the rotation wing 5 can be 2,3,4,6 (perhaps being designed to round tubular body).

Illuminating circuit 14 in the balanced controls is fixed in the closed housing 3, and illuminating circuit 14 comprises one or two luminotron at least, and makes the light hurdle 2 of the corresponding closed housing of the luminous light path outer of luminotron, and is outwards luminous by light hurdle 2.There is photoelectricity curtain sensor 4 in 2 outsides, light hurdle around 12 1 weeks of back shaft, photoelectricity curtain sensor 4 be by can discern 360 the degree and up and down each 80 the row photosensor arrays constitute.

When earthquake takes place, ground produces and rocks, balanced controls rock with ground, the light emitting diode 9 of illuminating circuit outwards sends light signal by light hurdle 2 in the balanced controls, and 2 outsides, light hurdle will be noted ground around the photoelectricity curtain sensor 4 in 12 1 weeks of back shaft and produce intensity and angle displacement information when rocking, and this information of photoelectricity curtain sensor 4 records outputs to computing machine by interface circuit 8 or remote control center is handled.But because photoelectricity curtain sensor 4 identification 360 degree and up and down photosensor arrays of each 80 row constitute.Therefore show that the ground situation of rocking will be all by photoelectricity curtain sensor 4 records when earthquake took place.

The earthquake information of photoelectricity curtain sensor 4 records can provide time, seismic location and relative intensity degree information.These information output to computing machine by interface circuit 8 or remote control center is handled.

Fig. 2 is the photoelectricity curtain sensor 4 record earthquake informations that computing machine or remote control center show by special software.Form among the figure by grid coordinates provide 360 the degree and up and down each 80 the row intensity scale values.Each value all is by photoelectric sensor 11 digital recordings in the photoelectricity curtain sensor 4.

Time when the starting point of the curve among the figure is the earthquake generation, vertical lattice are represented angle, are divided into 360 degree, and intensity is start bit with the thick black line of centre, are divided into 80 row up and down and represent intensity.Record 360 degree forward-reverse speed are increase and decrease representative degree of splitting suddenly.

During photoelectricity curtain sensor 4 record earthquake informations, carry out record,, can understand time situation in the generating process by each point of curve if know the time the when starting point of curve or earthquake take place with the unit interval.Certainly computing machine or remote control center also can be by clicking photoelectric sensor 11 position display angles, the time and intensity on each photoelectricity curtain sensor 4, because these a little information have all been carried out record by photoelectricity curtain sensor 4 by special software.
