Abstract
The utility model provides an earthquake science measuring instrument used for students, and belongs to the field of gas stoves. The earthquake science measuring instrument used for students is characterized by comprising an ampere meter, a resistance meter, a control rocker, a direction switch, electricity connecting ports, a wire, and a metal measuring stick. The ampere meter and the resistance meter are arranged side by side. The ampere meter and the resistance meter are respectively connected with the control rocker. An upper part and a lower part of a left side and a right side of the earthquake science measuring instrument used for students are respectively provided with one electricity connecting port. The electricity connecting port is connected with the wire, and the wire is connected with the metal measuring stick. The earthquake science measuring instrument used for students is simple in structure, low in manufacturing cost, and easy in use and operation.
Description
Technical field
The utility model student belongs to the seismic survey application with earthquake science popularization measuring instrument, and a kind of the exploration for student's science popularization of special design uses the student of record earth's surface activity data to use earthquake science popularization measuring instrument.
Background technology
For improving the student to the interest of popular science knowledge, enrich the remaining activity time of students in class, for the application of earthquake popular science knowledge, a kind of measuring instrument of measuring the earth's surface activity data is proposed.Because existing measuring instrument generally is to use for science and technology research, its cost is somewhat expensive, is not suitable for the science popularization Exploratory behavior, and therefore a kind of simple and easy and cheap earthquake science popularization measuring instrument just seems necessary.Active degree according to the earth's surface activity is different, and its earth's surface resistance is also different with electric current, therefore by measuring resistance and the current data of different time, observe the rate that changes, in conjunction with the situation of earth's surface activity, the changing value of resistance and current data when drawing earthquake is surveyed the earth's surface activity with this again.
The utility model content
The purpose of this utility model is to avoid the deficiencies in the prior art part, provides a kind of simple in structure, cheap, can be used by the student of student's self manufacture earthquake science popularization measuring instrument.
The purpose of this utility model is that following measures reaches, the student comprises reometer, ohmmeter, control rocking bar, direction switch, connects electricity mouth, wire, metal measuring stick with earthquake science popularization measuring instrument, reometer and ohmmeter are arranged side by side, reometer is connected the control rocking bar and is connected with ohmmeter, the student respectively is provided with respectively up and down one with earthquake science popularization measuring instrument the right and left and connects the electricity mouth, connect electricity mouthful connection wire, wire connection metal measuring stick.
The utility model is simple in structure, and is cheap, uses easy and simple to handle.
Description of drawings
Accompanying drawing 1 is structural representation of the present utility model.
Accompanying drawing 2 is circuit diagrams of the present utility model.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
Among the figure: reometer 1, ohmmeter 2, control rocking bar 3, direction switch 4, connect electricity mouthfuls 5, wire 6, metal measuring stick 7.
Shown in accompanying drawing 1, accompanying drawing 2, the utility model student comprises reometer 1, ohmmeter 2, control rocking bar 3, direction switch 4, connects electricity mouth 5, wire 6, metal measuring stick 7 with earthquake science popularization measuring instrument, reometer and ohmmeter are arranged side by side, reometer is connected the control rocking bar and is connected with ohmmeter, the student respectively is provided with respectively up and down one with earthquake science popularization measuring instrument the right and left and connects the electricity mouth, connect electricity mouthful connection wire, wire connection metal measuring stick.
By four metal measuring sticks are inserted in the earth's surface of all directions four direction, by forming a loop circuit with the earth's surface between the metal measuring stick, measure current data and resistance data by reometer and ohmmeter, by direction switch can the State selective measurements four direction resistance and current data between in twos, can State selective measurements resistance data or current data by the control rocking bar.
